Description

Relates distribution method and mobile management device of the present invention is mobile location information, acquires location information from the mobile in particular mounting the position detecting means, the moving object position for displaying the position of the moving object based on the acquired positioning information The present invention relates to an information distribution method and a mobile management device.

  2. Description of the Related Art Conventionally, in a mobile management system that manages the position of a mobile body that moves at an arbitrary point such as a vehicle, the mobile body equipped with the position detection means and the management center are connected via a wireless network and exchange data with each other. Yes. The management center periodically collects the position information of the moving objects and displays the position of each moving object on the map based on the collected position information. On the other hand, each moving body includes a map display unit together with a position detection unit, and displays its own position detected by the position detection unit on a map on the display. The management center confirms the position of each moving object displayed on the map and gives various instructions. However, since the position information of the moving body held by the management center is not distributed to each moving body, each moving body cannot confirm the position of another moving body.

  However, for example, during an emergency response, each mobile object may want to act while confirming not only its own position but also the position of another mobile object. For this reason, it is desired that the position information of the moving bodies collected by the management center is distributed to each moving body so that each moving body can display the positions of other moving bodies together with its own position.

Accordingly, a vehicle information transmission system has been proposed that acquires position information of fellow vehicles (moving bodies) in an emergency and displays the positions of other vehicles on the map along with the position of the own vehicle (for example, a patent). Reference 1).
JP 2005-258932 A

  However, even if the position information of all the moving bodies collected by the management center is simply distributed to each moving body and the positions of other moving bodies are displayed on each moving body, the positions can be displayed in real time. There is a problem that it is difficult.

  In the management center, it is not necessary to grasp the position of the moving body in real time, and therefore the position information of the moving body is collected at a constant cycle necessary and sufficient for management. Therefore, even if this position information is distributed and position display is performed using the distributed position information, there is a high possibility that the target moving body has already moved from the display point. For example, when the position information is collected every 5 minutes, the position information of up to 5 minutes before is distributed, so there is a case where it is confused when trying to use it for displaying the position of another moving body.

  In order to eliminate the time lag between the display and the actual position, it is necessary to collect the position information of the management center and distribute the position information to each moving body in real time. However, if the collection and distribution of location information are to be processed in real time, the amount of communication with each mobile unit increases, an excessive load is applied to the management center, and the processing of the management center may be delayed. Furthermore, if the number of mobile objects to be managed increases, the amount of communication increases dramatically, making real-time processing difficult. Further, there is a problem that the communication cost increases as the communication amount increases.

  On the other hand, since the mobile body side has to receive and process the positional information of all mobile bodies distributed in real time from the management center, a considerable load is applied. Further, for example, when tracking a predetermined moving body, if the positions of all the moving bodies are displayed on the screen, there is a problem that it becomes difficult to confirm the target moving body.

The present invention has been made in view of such points, and when necessary, a mobile body location information distribution method and mobile body management device capable of displaying the position of another mobile body on a map in real time. The purpose is to provide.

  In order to solve the above problem, a mobile body location information distribution method by a mobile body management device that generates and distributes display information based on position information collected from a plurality of mobile bodies, and reports an emergency occurrence Received a specific mobile object that selected a display target mobile object based on the distance from the point corresponding to the emergency, updated the display information delivery cycle, and confirmed the tracking target. The mobile body is a leader mobile body, and the display information is information that highlights the reader mobile body so that it can be distinguished from the other mobile bodies. Is provided.

  In addition, in order to solve the above-described problem, there is provided a mobile body location information distribution method by a mobile body management device that generates and distributes display information based on position information collected from a plurality of mobile bodies. When the report is received, based on the distance from the point corresponding to the emergency situation, the primary range moving body existing in a certain range and the secondary range moving body located outside the certain range are classified. When the tracking target is confirmed from the specific primary range moving body, the mobile body is the leader moving body, and the display information distributed to the secondary range moving body is the primary range moving body. There is provided a method of distributing mobile body position information, characterized in that only the leader mobile body among the mobile bodies is displayed.

  Further, in order to solve the above-mentioned problem, a mobile management device that generates and distributes display information based on position information collected from a plurality of mobiles. When a mobile object is selected based on the distance from the point corresponding to the situation, the display information distribution cycle is updated, and the tracking target is confirmed by the specific mobile object, the mobile object is read. There is provided a moving body management apparatus comprising: a moving body; and a control unit configured to display the display information so that the reader moving body is highlighted so as to be distinguishable from other moving bodies.
  Further, in order to solve the above-mentioned problem, a mobile management device that generates and distributes display information based on position information collected from a plurality of mobiles. Based on the distance from the point corresponding to the situation, the tracking target was confirmed by classifying the primary range moving body existing in a certain range and the secondary range moving body located outside the certain range. When received from the specific primary range mobile body, the mobile body is the leader mobile body, and the display information distributed to the secondary range mobile body is the leader mobile body of the primary range mobile body. There is provided a moving body management apparatus including a control unit that displays only the information.

  In the present invention, when a predetermined condition for displaying the position of another moving body is established in the moving body, the moving body to be subjected to position display is selected according to the distance from the predetermined point. Then, only for the selected target moving body, position information collection and distribution of display information in the distribution cycle are performed, and the positions of itself and other target moving bodies are displayed on the target moving body. In this way, by limiting the target mobile bodies, it is possible to greatly reduce the amount of communication compared to the case where the location information of all mobile bodies is transmitted, and at the same time, suppress the increase in the load of the mobile body management device. Can do. As a result, the moving body can display the position of the other moving body together with its own position with necessary and sufficient accuracy.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, the concept of the invention applied to the embodiment will be described, and then the specific contents of the embodiment will be described.
FIG. 1 is a conceptual diagram of the invention applied to the embodiment.

  The mobile object management system according to the present invention is arranged in a management center that manages a mobile object A (2a), mobile object B (2b),. A mobile unit management apparatus 1 that collects location information of a mobile unit and displays the location is connected via a wireless network. In addition, in the following description, when it is not necessary to limit a mobile body in particular, a number is not attached.

  The mobile object management apparatus 1 includes a position information storage unit 11 that stores the position information of all mobile objects to be managed, a periodic position information collection unit 12 that collects position information at a regular collection period, and a mobile unit on the display device of the management center. The map display means 13 for displaying the position of the mobile body, the mobile body display control means 14 for displaying the position of another mobile body on the mobile body when a predetermined condition is satisfied, and the position information of the mobile body that is the position display target in the distribution cycle Distribution period position information collecting means 15 for collecting and display information distributing means 16 for distributing display information for displaying the position of another moving body on the moving body are provided.

  The position information storage means 11 stores the position information of the moving body collected every periodic collection cycle or every delivery cycle set when a predetermined condition for displaying the position of another moving body is established in the moving body. The storage means is stored in association with the mobile object. The position information storage unit 11 stores other information necessary for position display along with the position information.

  The regular position information collecting means 12 normally collects the position information from all mobile objects to be managed in the regular collection cycle and stores the collected position information in the position information storage means 11. The normal time refers to a time during which a predetermined condition is not established.

  The map display means 13 arranges the positions of all the moving bodies on the map based on the map data and the position information of all the moving bodies stored in the position information storage means 11, and displays them on a display device (not shown).

  The mobile body display control means 14 checks whether or not a predetermined condition for displaying the position of another mobile body is established for each mobile body, and if so, all mobile bodies stored in the position information storage means 11 Based on the position information, a mobile body located within a certain range from a predetermined point is identified and set as a display target mobile body. The predetermined condition is a condition that makes it necessary to display the position of other moving bodies in each moving body, for example, when an instruction to start tracking of arbitrary moving bodies is issued at the same time. Predetermined points are points that are targets for movement of mobile objects, such as points where emergencies that cause the establishment of predetermined conditions have occurred, or points where targets that each mobile object must track Point to. Therefore, it may change with the elapsed time. Further, the distance from a predetermined point that determines a certain range is determined according to the moving speed of the target (predetermined point) and the moving speed of the moving body. In addition to the primary range within a distance X from a predetermined point, a plurality of ranges may be set such that the range is a secondary range further outside the distance Y from X from the predetermined point. Further, the identification of the target moving body is performed based on the renewed position information after collecting the position information of the selected target moving body after performing the primary determination based on the position information stored in the position information storage means 11. The target moving body may be set again. Furthermore, the mobile body display control means 14 sets a delivery cycle for delivering display information to the target mobile body. The delivery cycle is at least a cycle shorter than the periodic collection cycle in which the periodic position information collecting unit 12 executes collection, and a time during which the position display of the other mobile body by the mobile body can maintain necessary and sufficient accuracy is set. When a plurality of ranges such as a primary range and a secondary range are set, the setting of the distribution cycle may be changed according to the range. A delivery cycle to a mobile body in the primary range is a primary delivery cycle, and a delivery cycle to a mobile body in the secondary range is a secondary delivery cycle. The period is set so that the primary distribution period <secondary distribution period <regular collection period. When the predetermined condition is not satisfied, the setting of the target mobile body and the distribution cycle is canceled, and the processing by the distribution cycle position information collecting unit 15 and the display information distributing unit 16 is stopped.

  The distribution cycle position information collection unit 15 collects the position information from the target mobile unit for each distribution cycle set by the mobile unit display control unit 14 and stores the collected position information in the position information storage unit 11.

  The display information distribution unit 16 moves the display information used for the position display of the target moving body based on the position information collected by the distribution cycle position information collecting unit 15 for each distribution cycle set by the mobile body display control unit 14. Deliver to the body. In the display information, in addition to the position information of the target moving body, a display instruction such as a display color of an arbitrary target moving body, message information describing a message to be displayed, and the like are set. Further, when the process is stopped by the moving body display control unit 14, the process is stopped after notifying the target moving body of the stop of the display process based on the display information.

  The mobile object A (2a) is a position detection means 21 for detecting its own position, a map display means 22 for displaying its own position based on the map data, and a display based on the display information. Position information transmitting means 23 for transmitting to the apparatus 1 and display information receiving means 24 for receiving display information for position display of other moving bodies excluding itself from the moving body management apparatus 1 are provided. In addition, all the mobile bodies including the mobile body B (2b) have the same configuration.

  The position detecting means 21 is a detecting means for detecting the position of the moving object A (2a), and is, for example, a GPS (Global Positioning Systems). Position information is generated from the detected latitude and longitude.

  The map display means 22 displays the position of the moving object A (2a) on the map based on the map data and the position information generated by the position detecting means 21 at normal times when the display information is not distributed from the moving object management device 1. indicate. Further, when the display information receiving unit 24 acquires display information from the mobile body management device 1, the position of other mobile bodies, messages, and the like are displayed on the map based on the acquired display information.

The position information transmission unit 23 transmits the position information generated by the position detection unit 21 in response to a request from the mobile management device 1.
When the display information receiving unit 24 receives display information of another mobile unit from the mobile unit management device 1, the display information receiving unit 24 sends the received display information to the map display unit 22.

A moving object display method executed in the moving object management system having such a configuration will be described in the case where the moving object A (2a) is a target.
During normal times, that is, while the predetermined condition is not satisfied, the moving body A (2a) detects its own position by the position detection means 21 and generates position information. Further, the map display means 22 displays its own position on the map based on the generated position information and map data.

  On the other hand, in the moving body management apparatus 1, the periodic position information collecting unit 12 requests position information from the moving body A (2a) every periodic collection period. Then, the position information transmitted from the position information transmitting means 23 of the moving object A (2a) is stored in the position information storage means 11 in response to the request. The same processing is executed for mobile bodies other than the mobile body A (2a), and all the position information of the mobile bodies to be managed is collected. The map display means 13 displays a map and the position of each mobile object on the map on a display device (not shown) based on the position information and map data of each mobile object stored in the position information storage means 11. .

  As described above, at the normal time, the position of each mobile body to be managed is displayed on the map by the mobile body management apparatus 1 on the display device of the management center. The position display is updated every periodic collection cycle. On the other hand, in the display device of the moving object A (2a), only its own position is displayed on the map. The same applies to mobile bodies other than the mobile body A (2a).

  When a predetermined condition such as emergency response is established, the mobile object display control unit 14 exists within a certain range from a predetermined point based on the position information of each mobile object stored in the position information storage unit 11. A moving body is extracted and set as a target moving body to which display information is distributed. In addition, a distribution cycle for collecting position information from the target moving body and distributing display information to the target moving body is also set. The delivery cycle is set to a value (real time) that maintains display accuracy. In addition, when the secondary range is set on the outer side, the target moving body located in the secondary range and the secondary distribution cycle are also set. When the target mobile unit and the distribution cycle are set by the mobile unit display control unit 14, the distribution cycle position information collecting unit 15 collects the position information of the target mobile unit for each distribution cycle and stores it in the position information storage unit 11. To do. When there are a primary delivery cycle and a secondary delivery cycle, processing is performed for the corresponding mobile object in each cycle. The map display means 13 updates the display according to the updated position information. Moreover, the display information distribution means 16 produces | generates the display information of a target moving body based on the positional information stored in the position information storage means 11 for every delivery cycle, and distributes it to a target moving body.

  The moving body A (2a) is also a target moving body, and the display information received via the display information receiving means 24 is sent to the map display means 22. The map display means 22 displays the position of the target mobile body including the mobile body A (2a) on the map based on the display information, and displays the position of the mobile body A (2a) to the passenger of the mobile body A (2a) and a predetermined range. The position of the other moving body set as the target moving body is notified.

  As a result, while a predetermined condition such as an emergency response is established, the passenger of the moving body A (2a) located within the predetermined range can be moved to another mobile body within the predetermined range on the map. The position can be confirmed in real time. At this time, the same map display is also performed on other moving objects within a predetermined range. As a result, based on the display, it is possible to quickly and accurately link the moving bodies within the range.

  When the predetermined condition is not satisfied, the mobile object display control unit 14 detects this, cancels the setting of the target mobile object and the distribution cycle, and distributes the distribution cycle position information collection unit 15 and the display information distribution unit 16. Stop processing by. At this time, the display information distribution means 16 may stop the processing after notifying the target mobile body of the stop of the display process based on the display information, or receives the display information for a certain time on the mobile body A (2a) side. If not, the display may be automatically returned to display only its own position. Thus, the normal state before the predetermined condition is established is restored.

Hereinafter, an embodiment will be described in detail with reference to the drawings, taking as an example a case where the embodiment is applied to a position management system for a police vehicle (moving body).
A position management system for a police vehicle (hereinafter simply referred to as a vehicle) includes a vehicle-mounted terminal mounted on each vehicle and a vehicle management device that collects and manages position information from the vehicle-mounted terminal of each vehicle. Connected through. The vehicle management apparatus is installed in a management center that centrally manages vehicles, displays vehicle positions based on position information collected from moving vehicles on a map, and supports the position confirmation of the vehicle by an administrator. Hereinafter, this state is referred to as a normal mode.

  In police operations, in addition to vehicle management in the normal mode, vehicle management for emergency deployment is required. Hereinafter, the state in which the emergency response process is executed is referred to as an emergency response mode. In addition, emergency deployment refers to the initial action in which a large number of police officers are mobilized and deployed in an intensive manner in order to secure suspects (early clearance of criminals) in the event of an important criminal law crime. A form of investigative activity. Therefore, when the emergency deployment is instructed, each vehicle is instructed to track the moving target (suspect) in cooperation with a plurality of vehicles. At this time, if each vehicle that tracks the target can operate while confirming the position of each other in real time, an appropriate and smooth investigation activity can be performed. Therefore, in the present embodiment, while emergency deployment is issued, the position information of other vehicles that track the target is displayed in real time on the vehicle-mounted terminal mounted on each vehicle.

FIG. 2 is a diagram showing an outline of functions of the vehicle management system of the present embodiment.
The figure shows an example of a vehicle displayed on the display device of the management center. A vehicle A (51), a vehicle B (52), and a vehicle that move at any position in the entire map area 50 to be managed. The positions of C (53), vehicle D (54), and vehicle F (55) are displayed.

Here, when notified that an emergency has occurred, the vehicle management device enters an emergency response mode, and selects a vehicle within a predetermined range from the emergency occurrence point where the emergency occurred based on the notification. The predetermined range is, for example, a range in which it is assumed that there is a tracking target (suspect), and is calculated according to the elapsed time from the occurrence of an emergency, the moving speed of the tracking target, and the like. The predetermined range is set as a real-time communication range 56, a vehicle located within this range is set as an emergency response vehicle, the position information acquisition interval is set as a real-time cycle, and the acquired position information is distributed to all emergency response vehicles. In the example of the figure, vehicle A (51), vehicle B (52), and vehicle C (53) are selected as emergency response vehicles, and position information of each vehicle is collected and distributed in real time. Thereby, vehicle A (51), vehicle B (52), and vehicle C (53) located in the real-time communication range 56 can confirm each other's position with the vehicle mounting terminal of the own vehicle.

  When one of the vehicles confirms the target and issues a report, the vehicle management device that received the report highlights the display so that the notified vehicle can be the emergency leader and other vehicles can confirm it. To. In the example of the figure, when the vehicle B (52) becomes an emergency leader, the “vehicle B” display is set to “tracking vehicle Z”, and this is notified to each vehicle. The center of the real-time communication range 56 is a tracking vehicle Z (52) that is an emergency leader. As a result, the vehicle A (51), the vehicle B (52), and the vehicle C (53) can easily confirm the tracked vehicle Z (52) that is the tracking target. The emergency leader may be selected by the vehicle management device.

  Further, in the present embodiment, a short regular communication range 57 is provided outside the real-time communication range 56, and a vehicle located there is detected. In the illustrated example, the vehicle D (54) is detected. Since the vehicle located in the short regular communication range 57 is highly likely to enter the real-time communication range 56, the vehicle in this range is set as an emergency response candidate vehicle. For emergency response candidate vehicles, a short periodic period shorter than the regular periodic collection period and longer than the real-time period is set, and the location information of the emergency response candidate vehicles is acquired in a short period of time. Display on the display device to increase the accuracy of position confirmation. On the other hand, the position information of the tracking vehicle Z (52) serving as the tracking target is distributed to the emergency response candidate vehicle. Thereby, the vehicle D (54) can confirm the position of the tracking vehicle Z (52) as a tracking target with higher accuracy than usual.

The regular position management unit 111 performs processing in the emergency mode when the communication timing setting unit 112, the real-time information distribution unit 113, the short regular information distribution unit 114, and the regular information distribution unit 115 are in the normal mode.

  The regular position management unit 111 collects position information from each vehicle at each normal periodical collection period that is set in advance in the normal mode, and stores the collected position information in the vehicle position information DB 106b. Further, the position of each vehicle is displayed on the map based on the data stored in the vehicle position information DB 106b and the map data DB 106a. Furthermore, the issue of the emergency deployment command is checked, and if issued, the management processing unit 110 is shifted to the emergency response mode.

In the emergency response mode, the communication timing setting unit 112 specifies the position of the tracking vehicle or the emergency occurrence point obtained from the latest vehicle position information stored in the vehicle position information DB 106b, and the real-time communication range 56 and the short periodical A communication range 57 is determined. Moreover, the distribution cycle of each communication range is set. Here, it is assumed that the real-time communication range 56 is set to a real-time cycle, and the short regular communication range 57 is set to a short regular cycle.

  The real-time information distribution unit 113 refers to the vehicle position information DB 106b, extracts vehicles selected as emergency response vehicles, collects position information from the emergency response vehicles, and updates the vehicle position information DB 106b for each real-time cycle.

The emergency deployment command / command 413 indicates whether the emergency deployment is commanded. It is set when an emergency deployment is issued and reset when an emergency deployment is canceled. The suspicious person (suspected vehicle) tracking notification 414 is set in response to a notification that tracking of the suspected person (suspected vehicle) at the time of emergency deployment is started. Each vehicle is searching for a tracking target suspect (suspected vehicle), and if found, notifies the vehicle management apparatus 100. The vehicle management apparatus 100 detects the notification and sets that there is a notification in the corresponding vehicle column. In the tracking vehicle flag 415, identification information for identifying the tracking vehicle is set. For example, when the tracked vehicle is indicated by “Z” at the time of display, “Z” is set in the column corresponding to the vehicle selected as the tracked vehicle. In the vehicle position information 416, the position coordinates of the vehicle are set. In the example of the figure, the position of the two-dimensional coordinate is indicated by (x, y) coordinates. In the communication timing 417, a communication timing determined for each vehicle ("regular" at normal time / "real time" within the real-time communication range / "short-period" within the short regular communication range) is set. The communication timing set for each vehicle is determined according to the determination result of the range where the vehicle is located by the communication timing setting unit 112. The real-time flag 418 is set when collection / distribution processing is performed in a real-time cycle for the corresponding vehicle. The short regular flag 419 is set when collection and distribution are performed for the corresponding vehicle in a short regular cycle.

  In the normal mode, no setting is registered in the emergency deployment command / command 413, the suspect (suspected vehicle) tracking notification 414, and the tracking vehicle flag 415 for all vehicles. Further, the communication timing 417 is all set to “periodic”, and the real-time flag 418 and the short periodical flag 419 are also set to OFF.

  Next, the state of the vehicle position information in the emergency response mode will be described. FIG. 6 is a diagram illustrating a configuration example of vehicle position information (during emergency deployment) according to the present embodiment. The same elements as those in FIG.

  The vehicle position information (during emergency deployment) 410b indicates a state after the emergency deployment is commanded from the state of the vehicle position information (normal time) 410a shown in FIG. By issuing an emergency deployment, “emergency deployment” is set in all vehicle situations 412. Further, when a report is received from the vehicle that has started tracking the suspect, the suspect (suspected vehicle) tracking notification 414 and the tracking vehicle flag 415 of the vehicle that has reported are set. The tracking vehicle may be set by the vehicle management device 100 or the administrator, for example, selecting a vehicle closest to the emergency occurrence point. The figure shows an example in the case where a report is issued from the vehicle B, where “tracking start” is set in the suspected person (suspected vehicle) tracking notification 414 corresponding to the vehicle B, and the tracking vehicle Z is set in the tracking vehicle flag 415. The

  Further, “real time” is set in the corresponding communication timing 417 for a vehicle located in the real time communication range 56 set around the tracking vehicle Z. In the example of the figure, the vehicle A, the vehicle B, and the vehicle D are set. Similarly, “short period” is set in the corresponding communication timing 417 for the vehicle located in the short period communication range 57. The real-time flag 418 and the short regular flag 419 represent the execution status of the real-time information distribution unit 113, the short regular information distribution unit 114, and the regular information distribution unit 115. In each process, it is turned ON / OFF when the distribution process is completed.

Hereinafter, when there is no need to limit in particular, it will be described as vehicle position information 410.
The investigation range DB 106 c stores parameters for calculating the real-time communication range 56 and the short regular communication range 57.

FIG. 7 is a diagram illustrating a configuration example of the investigation range information according to the present embodiment.
In the search range information 420 stored in the search range DB 106c, X (real-time communication range) 422 and Y (short periodic communication range) 423 are stored in association with the escape method 421 of the tracking target (suspect).

  X (real-time communication range) 422 stores a calculation formula for X that defines the real-time communication range. Y (short regular communication range) 423 stores a calculation formula for Y that defines the short regular communication range. In the illustrated example, if the escape method 421 is “walking”, the X (real-time communication range) 422 is calculated as 2+ (elapsed time × 0.16) km. Similarly, 3+ (elapsed time × 0.4) for “bicycle” and 5 + elapsed time for “vehicle”. The elapsed time refers to the elapsed time from the emergency occurrence time heard from the reporter at the time of reporting. The communication timing setting unit 112 calculates X and sets the Xkm range as the real-time communication range with the emergency occurrence point or the tracking vehicle as the center. Also, Y is calculated, and a portion that is (X + Y) km from the center point common to the real-time communication range and that excludes the real-time communication range is set as the short regular communication range.

The vehicle IP address DB 106d stores the IP address of the vehicle to be managed.
FIG. 8 is a diagram illustrating a configuration example of vehicle IP address information according to the present embodiment.
In the vehicle IP address information 430 stored in the vehicle IP address DB, an IP address 432 of the vehicle is set in association with the vehicle name 431. The management processing unit 110 refers to the IP address and performs communication processing with each vehicle.

The emergency deployment DB 106e stores the contents of the emergency deployment being issued.
FIG. 9 is a diagram showing a configuration of emergency deployment information according to the present embodiment.
The emergency deployment information (normal time) 440a stored in the emergency deployment DB 106e indicates data setting in a state where emergency deployment is not issued. Moreover, emergency deployment information (at the time of emergency deployment) 440b has shown the data setting in the state where emergency deployment is instructed.

  The case identifier 441 is identification information for identifying an emergency deployment command, and it is possible to search registration information regarding detailed contents of emergency deployment from the identifier. The emergency deployment information 440a and 440b are associated with the case identifier 441, an emergency deployment command 442 indicating the current state of the issued emergency deployment command, an emergency deployment cancellation 443 set when the emergency deployment command is canceled, and tracking A tracking vehicle 444 that specifies an emergency leader set in the vehicle, an escape method 445 indicating an escape method to be tracked, and an emergency occurrence date and time 446 are set.

  No information is set in the emergency deployment information (normal time) 440a in a state where no emergency deployment is issued. On the other hand, in the example of the figure, the emergency deployment information (at the time of emergency deployment) 440b after the emergency deployment is issued is associated with the case identifier 441, “emergency is issued” in the emergency deployment announcement 442, and “vehicle is in the tracking vehicle 444”. “B”, “Vehicle” is set in the escape method 445, and “3/31 AM 10:00” is set in the occurrence date and time 446.

Hereinafter, when it is not necessary to limit in particular, it is described as emergency deployment information 440.
The real-time DB 106f stores vehicle information detected in the real-time communication range 56 and selected as an emergency response vehicle.

FIG. 10 is a diagram showing a configuration of real-time information according to the present embodiment.
In the real-time information 450 stored in the real-time DB 106f, an emergency response vehicle to be subjected to real-time communication is set together with the IP address 452 associated with the vehicle name 451. In the example of the figure, vehicle A, vehicle B, and vehicle D are set.

  Here, the DB stored in the HDD 208 of the vehicle-mounted terminal 200 will be described. As shown in FIG. 3, the vehicle-mounted terminal 200 has a map data DB 208a and a reception data DB 208b.

Similar to the vehicle management apparatus 100, the map data DB 208a stores map data to be displayed on the display screen.
The received data DB 208b stores data transmitted from the vehicle management device 100 to the vehicle-mounted terminal 200 in the emergency response mode.

FIG. 11 is a diagram showing a configuration of received data information according to the present embodiment.
The received data information (tracked vehicle) 460a stored in the received data DB 208b is an example of data stored in the tracked vehicle designated as the emergency leader, and the received data information 460b is stored in other emergency response vehicles. It is an example of data.

  The received data information 460a, 460b includes a message 461 displayed on the display screen, another vehicle (information) 462 regarding other vehicles located in the real-time communication range, and a tracking vehicle indicating whether the vehicle of the other vehicle 462 is a tracking vehicle. It has a flag 463.

  In the example of the figure, in the received data information (tracking vehicle) 460a, “Now dispatching order” is stored in the message 461, and “Vehicle A” and “Vehicle D” in the real-time communication range are stored in the other vehicle 462. The vehicle coordinates are stored. Based on these pieces of information, the vehicle-mounted terminal 200 displays other vehicles on the map along with “Now dispatching order”.

  Further, in the other vehicle 462 of the emergency response vehicle 460b that is located in the real-time communication range and is not a tracking vehicle, “vehicle B” and “vehicle D” in the real-time communication range and the vehicle coordinates thereof are stored. Is done. The tracking vehicle flag 463 is set so that “vehicle B” is the tracking vehicle and the vehicle name is highlighted in blue.

  Although not shown, when the vehicle is an emergency response candidate vehicle located in the short period communication range, only the tracking vehicle information is set in the other vehicle 462. In the tracking vehicle flag 463, an instruction to highlight the vehicle name in another color (other than blue) is set.

When the vehicle is located outside the short period communication range, only the message 461 is set.
Next, the operation of the vehicle management system and the vehicle display method will be described sequentially using the management center and the vehicle display screen. Also, assume that processing is performed using the data examples shown in FIGS.

FIG. 12 is a diagram showing an example of a display screen in the normal mode in the vehicle management system of the present embodiment. A, B, and D in the figure represent vehicle A, vehicle B, and vehicle D, respectively.
In the normal mode, the regular position management unit 111 collects the position information of all the vehicles every regular collection period, and displays the position of each vehicle on the display device of the management center based on the position information. In the management center display screen 501, the vehicles A, B, and D are displayed on a map indicating positions that are specified based on the collected position information.

  On the other hand, in the normal mode, the regular position management unit 111 does not distribute the position information to each vehicle. Therefore, the position information detected by the position detection unit of the own device is displayed on the display screen of the vehicle-mounted terminal 200 of each vehicle. The position of the own vehicle is displayed. In the illustrated example, the position of the vehicle B is displayed on the vehicle B display screen 511 of the vehicle B. Similarly, the vehicle A display screen 521 displays the position of the vehicle A, and the vehicle D display screen 531 displays the position of the vehicle D.

  Here, it is assumed that an emergency occurred at “3/31 AM 10:00” to the police, and that the suspect had escaped in “vehicle” and emergency deployment was announced. As a result of the notification, emergency deployment information 440 is set, “emergency deployment” is set in the vehicle situation 412 corresponding to the emergency case response vehicle in the vehicle position information 410, and “present” is set in the command / command 413 for emergency deployment.

  When the emergency deployment is issued, the regular location management unit 111 changes the operation mode from the normal mode to the emergency response mode, the communication timing setting unit 112, the real-time information distribution unit 113, the short regular information distribution unit 114, and the regular information. The emergency deployment response process by the distribution unit 115 is started.

FIG. 13 is a diagram showing an example of a display screen at the start of the emergency response mode in the vehicle system of the present embodiment.
The management processing unit 110 distributes the message information so that the message “tight dispatch order” is displayed for each vehicle when the normal mode is changed to the emergency response mode. The message is distributed all at once to emergency response vehicles determined according to the emergency response case. As a result, messages of “tight dispatching instructions” 512a, 522a, and 532a are displayed on all of the vehicle B display screen 512, the vehicle A display screen 522, and the vehicle D display screen 532.

  Next, X and Y are calculated based on the information of the emergency deployment information 440 and the investigation range information 420, and the real-time communication range 541 and the short periodic communication range 542 are determined around the emergency occurrence point based on the notification. The emergency response vehicle in 541 and the emergency response candidate vehicle in the short regular communication range 542 are selected. Since the escape method is “vehicle”, based on the investigation range information 420, X for determining the real-time communication range is calculated from 5 + elapsed time, and Y for determining the short periodic communication range is calculated from 0.5 + elapsed time / 10. Based on X thus calculated, a range inside the circle of radius X centering on vehicle B is defined as a real-time communication range 541. Further, a short regular communication range 542 is defined as a range inside the circle of radius (X + Y) with the vehicle B as the center and outside the real-time communication range 541. The elapsed time is the elapsed time from “3/31 AM 10:00”. In the example of the figure, vehicle A and vehicle B are selected as emergency response vehicles.

  Thereafter, it is assumed that there is a report that “vehicle B” has started tracking. In the vehicle position information 410, for example, as shown in the vehicle position information (during emergency deployment) 410b, “tracking start” is set in the suspect (suspected vehicle) tracking notification 414 corresponding to “vehicle B”.

  The management processing unit 110 sets the vehicle B as the emergency leader vehicle and sets “Z” representing the tracked vehicle in the tracked vehicle flag 415 when the tracking is started. Subsequently, the real-time communication range and the short regular communication range are calculated with the position of the tracking vehicle as the center. In this case, the real-time communication range 541 and the short regular communication range 542 are calculated with the vehicle B as the center. Thereafter, the vehicle B becomes the center of the real-time communication range 541 and the short regular communication range 542 until the emergency leader changes.

  Thus, the real-time communication range 541 centered on the emergency leader (tracking vehicle Z) and the short regular communication range 542 are calculated, and the communication timing setting unit 112 determines the emergency response vehicle located in the real-time communication range 541 and the short regular communication range. An emergency response candidate vehicle located in the communication range 542 is detected. In the example of the figure, vehicle A and vehicle B (emergency leader) are detected as emergency response vehicles, and emergency response candidate vehicles are not detected. Therefore, the communication timing 417 of the vehicle position information 410 corresponding to the vehicles A and B in the real-time communication range 541 is set to “real time”, and the communication timing 417 of the vehicle D outside the short-period communication range 542 is “ Set Periodic. The vehicle position confirmation by the communication timing setting unit 112 is performed at a cycle shorter than at least the real-time cycle. In addition, if position information is collected from vehicles determined to be in the real-time communication range 541 and the short periodic communication range 542, and the determination is performed again based on the collected latest position information, the old position information is erroneously detected. It is possible to prevent the determination and to make a highly accurate determination.

  The real-time information distribution unit 113 checks the vehicle position information 410 in the vehicle position information DB 106b for each real-time cycle, extracts the vehicles A and B for which “real time” is set in the communication timing 417, and registers them in the real-time information 450. . Then, using the IP addresses of the vehicles A and B set in the IP address 452 of the real-time information 450 as destinations, the location information is requested and the vehicle location information 410 is updated. Then, display information including updated latest position information of other vehicles in the real-time communication range 541 and an instruction of the tracking vehicle is transmitted to the vehicle A and the vehicle B. Also, the display device of the management center is updated based on the collected position information.

  Based on this information, the vehicle B displays the position of its own vehicle as the tracking vehicle Z as shown on the vehicle B display screen 512, and also displays the position of the vehicle A to which the position information is transmitted. As shown in the vehicle A display screen 522, the vehicle A displays the position of the vehicle B together with the position of the host vehicle as the tracking vehicle Z (522b). The tracking vehicle Z is highlighted by changing the display color (for example, blue). Thereafter, the position display of the tracking vehicle Z (vehicle B) and the vehicle A is updated in real time.

  As a result, even in the management center, for example, if the regular collection period is 1 minute and the real-time period is 1 second, the position of the vehicle that could only be confirmed every minute so far can be confirmed every second. . Further, the vehicles can grasp each other's position, and the occupant of the vehicle A can perform tracking while confirming the position of the tracking vehicle Z displayed in real time. In addition, the occupant of the tracking vehicle Z (vehicle B) can check in real time the position of the vehicle A that can be tracked other than the own vehicle, and can track in cooperation.

  The short regular information distribution unit 114 does not perform distribution processing because there is no corresponding vehicle. The regular information distribution unit 115 collects the position information from the vehicle D outside the short regular communication range 542, and updates the display on the display device of the management center. However, position information of other vehicles is not transmitted to the vehicle D. Accordingly, only the “tight dispatching instruction” 532 a is displayed on the vehicle D display screen 532 of the vehicle D.

Next, the case where the vehicle D that has been outside the short period communication range 542 from the state of FIG. 13 enters the short period communication range 542 will be described.
FIG. 14 is a diagram showing an example of a display screen when a vehicle enters the short period communication range in the emergency response mode in the vehicle system of the present embodiment.

As shown in the management center display screen 503, it is assumed that the vehicle D has entered the short regular communication range 542 from the outside of the short regular communication range 542.
The communication timing setting unit 112 compares the position of each vehicle with the real-time communication range 541 and the short regular communication range 542 based on the vehicle position information 410 and detects that the vehicle D has entered the short regular communication range 542. Therefore, the communication timing 417 corresponding to the vehicle D in the vehicle position information 410 is set to “short period”.

  The real-time information distribution unit 113 collects and distributes the position information of the vehicles A and B in the real-time communication range 541 in a real-time cycle. Accordingly, the positions of the vehicle A and the tracking vehicle Z (vehicle B) are updated and displayed in real time on the vehicle B display screen 513 and the vehicle A display screen 523. Since the vehicle located outside the real-time communication range 541 is not displayed, it is not displayed that the vehicle D has entered the short period communication range 542.

  When the short periodical information distribution unit 114 detects that the vehicle D has entered the short periodical communication range 542 based on the vehicle position information 410, the short periodical information distribution unit 114 collects the position information of the vehicle D and transmits the vehicle position information every short period. While updating 410, the tracking vehicle information, the positional information of the tracking vehicle Z, and the display information including a display message are distributed to the vehicle D. The display message is, for example, “A real-time communication range has been approached”. The position information is only for the tracking vehicle Z. In the vehicle D, the tracking vehicle Z (533a) and the message 533b are displayed along with the position of the own vehicle based on the received display information. At this time, the tracking vehicle Z (533a) is highlighted so that the tracking target can be immediately identified. In addition, a display color (for example, red) different from that of the tracking vehicle Z (522b) of the vehicle A that is an emergency response vehicle is set to distinguish them.

  For the short periodic period, when the real-time period is 1 second, a longer value, for example, 10 seconds is set. Therefore, although the position display of the vehicle D in the short regular communication range 542 has a lower accuracy than the emergency response vehicle, each option is displayed with sufficient accuracy on the display device of the management center. Further, the occupant of the vehicle D can recognize that the tracking target vehicle is approaching and the position of the tracking vehicle Z and prepare for tracking.

  When a certain period of time has elapsed since the transition to the emergency response mode, the periodic information distribution unit 115 distributes an instruction to each vehicle to update the message display of “tight dispatch order” to “during tight dispatch order”. To do. As a result, the message display on the vehicle B display screen 513, the vehicle A display screen 523, and the vehicle D display screen 533 is changed from “tight dispatch order” to “tight dispatch order”.

Next, a case where the vehicle D enters the real-time communication range 541 from the state of FIG. 14 will be described.
FIG. 15 is a diagram showing an example of a display screen when a vehicle enters the real-time communication range in the emergency response mode in the vehicle system of the present embodiment.

As shown in the management center display screen 504, it is assumed that the vehicle D has entered the real-time communication range 541 from the short regular communication range 542.
The communication timing setting unit 112 checks the position of each vehicle based on the vehicle position information 410 and detects that the vehicle D has entered the real-time communication range 541. Therefore, the communication timing 417 corresponding to the vehicle D in the vehicle position information 410 is set to “real time”. The vehicles B and A remain “real time”.

  The real-time information distribution unit 113 confirms the vehicle position information 410 for each real-time cycle, and registers the vehicle A, the vehicle B, and the vehicle D in the real-time information 450. Then, using the IP addresses of the vehicles A, B, and D set in the IP address 452 of the real-time information 450 as destinations, the location information is requested and the vehicle location information 410 is updated. Based on the updated position information, the position information of other vehicles in the real-time communication range 541 and the tracking vehicle information are transmitted to the vehicle A, the vehicle B, and the vehicle D.

  In the vehicle B, the position information of the newly distributed vehicle D is acquired, and the vehicle D (514a) is displayed on the vehicle B display screen 514. Similarly, vehicle D also displays vehicle D (524a) on vehicle A display screen 524. In the vehicle D, the vehicle A (534a) is displayed on the vehicle D display screen 534 based on the position information of the vehicle A that has been newly distributed due to entering the real-time communication range 541.

Next, the case where the vehicle A leaves the real-time communication range 541 from the state of FIG. 15 will be described.
FIG. 16 is a diagram showing an example of a display screen when the vehicle leaves the real-time communication range in the emergency response mode in the vehicle system of the present embodiment.

As shown in the management center display screen 505, it is assumed that the vehicle A that has been in the real-time communication range 541 has moved outside the real-time communication range 541.
The communication timing setting unit 112 checks the position of each vehicle based on the vehicle position information 410 and detects that the vehicle A has traveled outside the real-time communication range 541. Therefore, the communication timing 417 corresponding to the vehicle A in the vehicle position information 410 is set to “short period”. The vehicles B and D remain “real time”.

  The real-time information distribution unit 113 confirms the vehicle position information 410 for each real-time cycle, and registers the vehicle B and the vehicle D in the real-time information 450. Then, the position information is collected from the vehicles B and D, and the vehicle position information 410 is updated. Then, based on the updated position information, the position information of other vehicles in the real-time communication range 541 and the tracking vehicle information are transmitted to the vehicle B and the vehicle D.

  The short regular information distribution unit 114 collects position information from the vehicle A whose communication timing is set to “short regular period” for each short regular period, and reflects it on the management center display screen 505. Further, the position information of the vehicle B corresponding to the tracking vehicle Z and the tracking vehicle information of the tracking vehicle Z = the vehicle B are distributed to the vehicle A. In addition, the message “I have left the real-time communication range” is transmitted.

  In the vehicle A, the host vehicle (vehicle A), the tracking vehicle Z (525a), and the message 525b are displayed on the vehicle A display screen 525 based on the transmitted position information, tracking vehicle information, and message information. The tracking vehicle Z (525a) is displayed differently from the display when the host vehicle is in the real-time communication range 541.

In the vehicle B, the vehicle D (514a) is displayed on the vehicle B display screen 515 based on the delivered position information of the vehicle D. The display of the vehicle A outside the real-time communication range 541 disappears. Similarly, also in the vehicle D, only the tracking vehicle Z is displayed on the vehicle D display screen 535.
Next, the case where the vehicle A further moves away from the real-time communication range 541 and also away from the short-period communication range 542 from the state of FIG.

FIG. 17 is a diagram showing an example of a display screen when the vehicle leaves the short period communication range in the emergency response mode in the vehicle system of the present embodiment.
As shown in the management center display screen 506, it is assumed that the vehicle A that has been in the short regular communication range 542 has advanced to the outside.

  The communication timing setting unit 112 checks the position of each vehicle based on the vehicle position information 410 and detects that the vehicle A has traveled out of the short period communication range 542. Therefore, the communication timing 417 corresponding to the vehicle A in the vehicle position information 410 is set to “periodic”. The vehicles B and D remain “real time”.

  The real-time information distribution unit 113 checks the vehicle position information 410 every real-time cycle (1 second), and registers the vehicle B and the vehicle D in the real-time information 450. Then, the position information is collected from the vehicles B and D, and the vehicle position information 410 is updated. Then, based on the updated position information, the position information of other vehicles in the real-time communication range 541 and the tracking vehicle information are transmitted to the vehicle B and the vehicle D.

  The regular information distribution unit 115 collects the position information from the vehicle A outside the short regular communication range 542 and updates the display on the display of the management center. On the other hand, the position information of other vehicles is not transmitted to the vehicle A, but only the message “out of real-time communication range” is transmitted. Therefore, only the position of the host vehicle (vehicle A) and the message 526a are displayed on the vehicle A display screen 526 of the vehicle A.

Next, a case where emergency deployment is canceled will be described.
FIG. 18 is a diagram illustrating an example of a display screen when the emergency deployment is canceled in the vehicle system of the present embodiment.

  When the emergency deployment is canceled, the vehicle management device 100 distributes the message “restricted dispatch” to each vehicle in response to the emergency case, and displays the message on the display screen. Further, all information such as the communication timing, real time flag, and short period flag set in the vehicle position information 410 is deleted, and the vehicle position information 410 is returned to the state of the vehicle position information (normal time) 410a. And it changes to emergency mode from emergency response mode. In the normal mode, the position information of each vehicle is collected regularly, but the position information of other vehicles is not distributed. Therefore, the positions of all vehicles are displayed on the management center display screen 507 based on the position information collected periodically.

  Since the vehicle B does not receive position information, the position of the host vehicle (vehicle B) is displayed on the vehicle B display screen 517, and the position display of other vehicles is deleted. Also, the distributed message “canceled release” is displayed. Similarly, only the position and message of the host vehicle (vehicle A) are displayed on the vehicle A display screen 527 for the vehicle A as well. Also on the vehicle D display screen 537, only the position and message of the host vehicle (vehicle D) are displayed.

  As described above, in the present embodiment, the vehicle management device 100 specifies the tracking vehicle Z, and is positioned in real time only with the vehicle positioned within the predetermined real-time communication range with the tracking vehicle Z as the center. Collect and distribute information. As described above, since the communication target is limited to vehicles in the range closest to the tracking vehicle Z, real-time communication can be performed without increasing the load on both the vehicle management device 100 side and the vehicle-mounted terminal 200 side. .

  In addition, a short regular communication range is provided outside the real-time communication range, and position information is collected from vehicles in the short regular communication range for a period longer than the real-time period and shorter than the regular period, and displayed on the display device of the management center. ing.

  In this way, the emergency response vehicle within the real-time communication range that is the mainstay of tracking and for which the position is most desired to be confirmed can be confirmed in real time on the display device of the management center. Further, the position of the emergency response candidate vehicle that is likely to enter the real-time communication range is displayed on the display screen with relatively high accuracy. Therefore, the headquarters (administrator) can give accurate instructions based on highly accurate position information, and can support appropriate and smooth investigation activities.

  Furthermore, since the position of the other vehicle that is being tracked is also displayed on the display screen in real time in each vehicle, it is possible to perform the tracking while confirming the position of the other vehicle. That is, not only an instruction from the headquarters but also a passenger of the vehicle at the site can make a quick and accurate judgment by referring to the display.

  In the above description, the emergency response vehicle and the emergency response candidate vehicle are selected by the communication timing setting unit 112. However, the real-time information distribution unit 113 and the short-term information distribution unit 114 perform selection during distribution processing. It is good.

  As described above, the vehicle display method and the vehicle position management system according to the present embodiment can improve the activity efficiency related to searching and tracking of the suspected vehicle and the like, and can improve the probability of finding / securing the suspected vehicle at an early stage. . Furthermore, the amount of communication is limited, and the communication cost can be kept low.

Next, a processing procedure of the vehicle (moving body) display method according to the embodiment of the present invention will be described.
FIG. 19 is a flowchart showing a processing procedure of the vehicle display method of the present embodiment.
First, it operates in the normal mode, and transitions to the emergency response mode when an emergency deployment is issued.

[Step S01] Position information collection processing in the normal mode set in advance is performed.
[Step S02] It is determined whether an emergency deployment command or command has been issued. If so, the process proceeds to step S04.

  [Step S03] When the emergency deployment is not issued, an instruction to end the message display is distributed to each vehicle, and the display of “Now dispatching tightly” is deleted from each vehicle. The delivery of the message display end instruction may be executed when necessary, such as when returning from the emergency response mode to the normal mode. Thereafter, the process returns to step S01, and the processing in the normal mode is continued.

  [Step S04] When an emergency deployment command or command is issued, an instruction to display a “tight dispatch command” message is distributed to the vehicle corresponding to the emergency case. The vehicle to be distributed is selected according to the contents of the emergency deployed case with reference to the emergency deployment information 440. Then, “emergency deployment” is set in the vehicle status column corresponding to the selected vehicle in the vehicle position information 410, and the command / command for emergency deployment is set to “present”. Further, the operation mode is changed from the normal mode to the emergency response mode, and the following procedure is repeated until the emergency deployment is canceled.

  [Step S05] With reference to the data of the vehicle position information 106b, the emergency deployment 106e, and the investigation range 106c, the communication timing of each vehicle is set. Details of the processing will be described with reference to FIG.

[Step S06] It is determined whether it is a real-time communication timing. If it is not the real-time communication timing, the process proceeds to step S08.
[Step S07] Real-time distribution processing is performed for a vehicle whose communication timing is set to “real time”. Details of the processing will be described with reference to FIG.

[Step S08] It is determined whether it is the timing of the short periodical communication. If it is not the timing of the short periodical communication, the process proceeds to step S10.
[Step S09] A short-period delivery process is performed for a vehicle for which “short period” is set as the communication timing. Details of the processing will be described with reference to FIG.

[Step S10] It is determined whether it is the timing of regular communication. If it is not the timing of regular communication, the process proceeds to step S12.
[Step S11] Periodic distribution processing is performed for vehicles for which “periodic” is set as the communication timing. Details of the processing will be described with reference to FIG.

[Step S12] It is determined whether or not emergency deployment is cancelled. If canceled, the process proceeds to step S16.
[Step S13] If the emergency deployment has not been canceled, the tracking notification of the vehicle position information 410 is confirmed, and it is determined whether or not the tracking vehicle has changed. If they are the same, the process proceeds to step S15.

[Step S14] If the tracked vehicle is different, the Z setting of the tracked vehicle flag in the vehicle position information 410 is moved to the vehicle that has newly become the tracked vehicle.
[Step S15] The display instruction of the message “Now dispatching order” is distributed to the vehicle corresponding to the emergency case, and “Now dispatching order” is displayed on each vehicle. Thereafter, the process proceeds to step S05, and the emergency response process is continued.

[Step S16] When the emergency deployment is cancelled, the display instruction of the message “tight dispatch cancellation” is distributed to the vehicle corresponding to the emergency case, and the “strict dispatch cancellation” is displayed on each vehicle.
[Step S17] The vehicle data corresponding to the tightly distributed case in the vehicle position information 410 is updated to the value in the normal mode. That is, the communication timing is “periodic”, the real-time flag is cancelled, and the short periodic flag is cancelled. Also, the setting of the tracking vehicle flag is reset. Thereby, it returns to the state of vehicle position information (normal time) 410a.

  [Step S18] It is determined whether there is an instruction to terminate the system. If there is no system termination instruction, the process returns to step S01 to start processing in the normal mode. If there is a system termination instruction, the process is terminated.

  By executing such processing procedure, in the normal mode, normal position information collection (step S01) is executed, and the position of each vehicle is displayed only on the display of the management center. When an emergency deployment is instructed, communication timing setting (step S05), real-time distribution processing (step S07), short periodic distribution processing (step S09), and periodic distribution processing (step S11) are executed, and the real-time communication range The vehicle position information is collected in real time, and the vehicle position information in the short regular communication range is collected in a short period and reflected on the display of the management center. In addition, position information of vehicles in the real-time communication range is distributed to each vehicle in the real-time communication range, and position information of the tracking vehicle is distributed to vehicles in the short-term communication range so that the position of other vehicles can be confirmed by each vehicle. become.

  Hereinafter, position information collection processing in the normal mode (S01), communication timing setting processing in the emergency response mode (S05), real-time distribution processing (S07), short regular distribution processing (S09), and regular distribution processing (S11) Detailed processing will be described.

First, processing in the normal mode will be described.
FIG. 20 is a flowchart showing the position information collection processing procedure in the normal mode of the present embodiment.

[Step S101] It is checked whether or not it is a periodical reception timing for collecting position information in the normal mode. If it is not the regular reception timing, the process is terminated.
[Step S102] If it is a regular reception timing, position information of each vehicle to be managed is acquired. For each vehicle IP address set in the vehicle IP address information 430, a position information request is sequentially transmitted, and the position information is received as a response.

[Step S103] Based on the received position information, the vehicle position information 416 of the vehicle position information 410 is updated.
[Step S104] Based on the updated data of the vehicle position information 410, the display of the management center is updated, and the latest position of each vehicle is displayed on the map.

  By executing the above processing procedure, the position of each vehicle is displayed on the map display of the management center in the normal mode. Further, the position of each vehicle is updated at a regular timing in the normal mode. On the other hand, position information is not distributed to each vehicle.

Next, processing in the emergency response mode will be described.
FIG. 21 is a flowchart showing a communication timing setting process procedure in the emergency response mode of the present embodiment.

  Emergency deployment is commanded and processing is started. In the process so far, as shown in the vehicle position information (at the time of emergency deployment) 410b, “present” is set in the command / command of emergency deployment for the emergency response vehicle. In addition, if it is notified that the suspect (suspected vehicle) has been found and tracking has been started, “tracking start” is set in the suspected person (suspected vehicle) tracking notification corresponding to the vehicle that made the notification, and tracking is performed. The vehicle flag is set. The tracking vehicle may be set by the management center.

  [Step S501] The tracking vehicle flag in the vehicle position information 410 is searched to detect the tracking vehicle Z. And the position information is requested | required with respect to the vehicle corresponding to the tracking vehicle Z, and the newest position information is obtained. The acquired position information is stored in the vehicle position information 410.

  [Step S502] Based on the suspect's escape method stored in the emergency deployment information 440, an X (real-time communication range) calculation method is selected from the search range information 420, and X is calculated.

  [Step S503] Similar to step S502, based on the suspect's escape method stored in the emergency deployment information 440, a Y (short periodic communication range) calculation method is selected from the search range information 420, and Y is calculated. .

[Step S504] The position information of the emergency response vehicle is read from the vehicle position information 410, and a determination procedure for determining whether or not each of the following vehicles is located in the real-time communication range is started.
[Step S505] The target vehicle α to be determined is set as the vehicle in the first record of the vehicle position information 410.

  [Step S506] Based on the position information of the target vehicle α, it is determined whether the target vehicle α is located within a radius Xkm around the tracked vehicle Z. If not within X, the process proceeds to step S510.

  [Step S507] When the target vehicle α is located within the radius Xkm (real-time communication range) from the tracked vehicle Z, position information is acquired from the target vehicle α, and the latest position information is stored in the vehicle position information 410.

  [Step S508] Based on the latest position information of the target vehicle α, it is confirmed whether the target vehicle α is located within the radius Xkm (real-time communication range) from the tracked vehicle Z. Since the position information used in step S506 is not the latest, the current position is confirmed and the determination is performed again. If not within X, the process proceeds to step S510.

  [Step S509] When it is confirmed that the target vehicle α is located within the radius Xkm (real-time communication range) from the tracked vehicle Z, “real time” is set in the communication timing column corresponding to the target vehicle α in the vehicle position information 410. Then, the process proceeds to step S512.

  [Step S510] When the target vehicle α is not located within the radius Xkm (real-time communication range) from the tracked vehicle Z, it is confirmed whether the communication timing column corresponding to the target vehicle α in the vehicle position information 410 is “real time”. To do. If not, the process proceeds to step S512.

  [Step S511] When the target vehicle α is not in the real-time communication range and “real time” is set in the corresponding communication timing column, the communication timing column is updated to “periodic”.

[Step S512] It is confirmed whether α is the last record. If it is the last record, the process ends.
[Step S513] If α is not the final record, α is advanced to the next record, and the processing from step S506 is performed on the next target vehicle.

  By executing the above processing procedure, it is determined whether or not each vehicle corresponding to the emergency case is located in the real-time communication range. If “real time” was previously set, “periodic” is set.

FIG. 22 is a flowchart showing a real-time delivery processing procedure in the emergency response mode of the present embodiment.
After the communication timing setting (step S05) in FIG. With the communication timing setting, the vehicle in the real-time communication range has the communication timing column of the vehicle position information 410 set to “real time”.

  [Step S701] The communication timing column of the vehicle position information 410 is searched, a vehicle whose communication timing column is “real time” is extracted, and the real time information 450 is set with reference to the vehicle IP address information 430.

[Step S702] The target vehicle α to be subjected to real-time distribution is set as the first record of the real-time information 450.
[Step S703] The display on the display of the management center is updated. In addition, since the latest position information of the vehicle in the real-time communication range including the target vehicle α is acquired in the communication timing setting (step S05), the position information is not collected again here. The position display of the vehicle in the real-time communication range on the display of the management center is updated based on the position information acquired in the communication timing setting (step S05).

[Step S704] With reference to the real-time information 450, the position information of other vehicles set in the real-time information 450 is extracted from the vehicle position information 410.
[Step S705] The vehicle position information 410 is searched to detect a vehicle for which the tracking vehicle flag is set. If not detected, the process proceeds to step S707.

  [Step S706] A display change instruction for highlighting a vehicle for which the tracking vehicle flag is set is set. For example, an instruction is given to change the name of the tracked vehicle or to display the display color in a color different from other vehicles. Note that the vehicle management device side may only specify the tracking vehicle, and the vehicle name or display color may be changed on the vehicle-mounted terminal side.

  [Step S707] The position information of the other vehicle extracted in step S704 and the display instruction when the display instruction of the tracking vehicle is set in step S706 are distributed to the target vehicle α.

[Step S708] The contents of the vehicle position information 410 are updated. The real-time flag of the target vehicle α is turned on and the short period flag is turned off.
[Step S709] It is confirmed whether α is the last record. If it is the last record, the process ends.

[Step S710] If α is not the final record, α is advanced to the next record, and the processing from step S704 is performed on the next target vehicle.
By executing the above processing procedure, the position information of other vehicles in the real-time communication range is distributed to the vehicles in the real-time communication range based on the position information collected in real time. Thereby, in each vehicle, other vehicles in the real-time communication range can be displayed in real time on the display of the own vehicle. At this time, the tracked vehicle is highlighted so that the position of the tracked vehicle as the tracking target can be easily grasped. The display on the management center side also updates the position display in real time for vehicles in the real-time communication range.

FIG. 23 is a flowchart showing a procedure for short-period delivery processing in the emergency response mode of the present embodiment.
After the communication timing setting (step S05) in FIG. With the communication timing setting, the vehicle in the real-time communication range has the communication timing column of the vehicle position information 410 set to “real time”.

[Step S <b> 901] The target vehicle α to be subjected to short-period delivery is set in the first record of the vehicle position information 410.
[Step S902] The communication timing of the target vehicle α is read from the record, and it is confirmed whether or not the communication timing is set to “real time”. If it is real time, the process proceeds to step S913, and the subsequent short periodical distribution process is not performed.

  [Step S903] When “real time” is not set in the communication timing of the target vehicle α, the position information of the target vehicle α is read, and X (real time communication range) and Y (calculated in the communication timing setting (step S05)) are read. (Short periodic communication range) is used to determine whether the target vehicle α exists within a radius (X + Y) km centered on the tracking vehicle Z. If not (X + Y), the process proceeds to step S907.

  [Step S904] If the target vehicle α is within a radius (X + Y) range centered on the tracked vehicle Z, it is determined that the target vehicle α is within the short period communication range. (Vehicles in the real-time communication range are excluded in step S902.) Then, the position information is acquired from the target vehicle α, and the latest position information is stored in the vehicle position information 410.

  [Step S905] Based on the latest position information of the target vehicle α, it is confirmed whether the target vehicle α is located within a radius (X + Y) km (short period communication range) from the tracked vehicle Z. Since the position information used in step S903 is not the latest, the current position is confirmed and the determination is performed again. If not (X + Y), the process advances to step S907.

  [Step S906] When it is confirmed that the target vehicle α is located within the radius (X + Y) km (short regular communication range) from the tracked vehicle Z, the communication timing column corresponding to the target vehicle α in the vehicle position information 410 is displayed. “Short period” is set, and the process proceeds to step S908.

  [Step S907] When the target vehicle α is not located within the radius (X + Y) km (short regular communication range) from the tracking vehicle Z, “periodic” is set as the communication timing corresponding to the target vehicle α in the vehicle position information 410. Then, the process proceeds to step S913, and the subsequent short periodical distribution process is not performed.

  [Step S908] It is determined whether or not the target vehicle α is within the short period communication range including the real time communication range at the time of the previous processing. Specifically, the vehicle position information 410 is searched to determine whether or not the real-time flag or the short period flag of the target vehicle α is ON. If not within the short period communication range, the process proceeds to step S910.

  [Step S909] If the target vehicle α is still within the short-term communication range at the time of the previous processing, the message “I have left the real-time communication range” is transmitted to the target vehicle α, and a transmission message is displayed. Let Subsequently, after the real-time flag of the target vehicle α in the vehicle position information 410 is turned off and the short period flag is turned on, the process proceeds to step S911.

  [Step S910] When the target vehicle α is not located in the short period communication range at the time of the previous processing, that is, when the target vehicle α enters the short period communication range, the message “approaching the real time communication range” is displayed. "" Is transmitted to the target vehicle α, and a transmission message is displayed.

  [Step S911] The display on the display of the management center is updated. As a result, the latest position of the target vehicle α is displayed on the display of the management center based on the position information acquired in step S904.

  [Step S912] The position information of the tracking vehicle Z is distributed to the target vehicle α. At this time, in order to highlight the vehicle for which the tracking vehicle flag is set, an instruction is given to change the display color to a color different from the normal state.

[Step S913] It is confirmed whether α is the last record. If it is the last record, the process ends.
[Step S914] If α is not the final record, α is advanced to the next record, and the processing from step S902 is performed on the next target vehicle.

  By executing the above processing procedure, the position information of the tracked vehicle is distributed to the vehicles in the short period communication range. Thereby, in each vehicle, the tracking vehicle can be displayed on the display of the own vehicle in real time. At the same time, a message informs that it is close to the real-time communication range. In addition, the tracking vehicle is highlighted so that the position of the tracking vehicle as a tracking target can be easily grasped. Further, the display on the management center side also updates the position display in a short period for vehicles in the short period communication range.

FIG. 24 is a flowchart showing a regular delivery processing procedure in the emergency response mode of the present embodiment.
After the communication timing setting (step S05) in FIG. 21, it is activated at regular intervals. By the processing so far, “periodic” is set in the communication timing column of the vehicle position information 410 of the target vehicle.

[Step S <b> 1101] The target vehicle α that is the target of periodic distribution is set in the first record of the vehicle position information 410.
[Step S1102] The communication timing of the target vehicle α is read from the record, and it is confirmed whether or not “periodic” is set as the communication timing. If it is not “periodic”, the process proceeds to step S1108, and the subsequent periodic distribution process is not performed.

  [Step S1103] When “regular” is set as the communication timing of the target vehicle α, the real-time flag and the short periodic flag of the target vehicle α in the vehicle position information 410 are read. First, it is confirmed whether or not the real time flag is ON. If not ON, the process proceeds to step S1105.

  [Step S1104] If the real-time flag of the target vehicle α is ON, the target vehicle α is located in the real-time communication range in the previous process, so the message “Out of real-time communication range” is targeted. It transmits to the vehicle α and displays a transmission message. Subsequently, after turning off the real-time flag of the target vehicle α in the vehicle position information 410, the process proceeds to step S1108.

  [Step S1105] When the real-time flag of the target vehicle α is OFF, it is confirmed whether or not the short period flag of the target vehicle α read in Step S1102 is ON. If not, the process proceeds to step S1107.

  [Step S1106] If the short-term flag of the target vehicle α is ON, the target vehicle α is located in the short-term communication range in the previous process, so the message “Out of real-time communication range” is targeted. It transmits to the vehicle α and displays a transmission message. Subsequently, after the short period flag of the target vehicle α in the vehicle position information 410 is turned off, the process proceeds to step S1108.

  [Step S1107] When the short regular flag of the target vehicle is OFF, the target vehicle α acquires the position information from the target vehicle α because the communication timing is “periodic” even in the previous process, and the latest position information. Is stored in the vehicle position information 410.

  [Step S1108] The display on the management center is updated. Thereby, based on the position information acquired in step S1107, the latest position of the target vehicle α is displayed on the display of the management center.

  [Step S1109] It is determined whether the information on the target vehicle α is the final record of the vehicle position information. If it is the last record, the process ends. If it is not the last record, the process proceeds to the next step.

  [Step S1110] α indicating the target vehicle is changed to indicate the vehicle of the next record of the vehicle position information. And it returns to step S1102 and processes the next object vehicle.

  By executing the above processing procedure, position information is collected from a vehicle outside the short-term communication range including the real-time communication range, and the display on the management center side is updated. Only the host vehicle is displayed on the vehicle display. Further, when the vehicle is within the short period communication range in the previous process, a message that the vehicle is out of the real time communication range is notified on the display of the vehicle.

  Next, a processing procedure in the vehicle-mounted terminal 200 will be described. Here, a processing procedure for displaying a map on a display device based on received data and position information will be described. In the communication process, the position information is transmitted in response to the collection request from the vehicle management apparatus 100, and when the display data is received, the data is stored in the reception buffer.

FIG. 25 is a flowchart showing a processing procedure in the vehicle-mounted terminal according to the present embodiment.
[Step S21] It is determined whether or not the position information has been updated by the GPS 206 of the host vehicle. In this vehicle-mounted terminal 200, it is assumed that the display is updated at the timing of updating the position information of the host vehicle. If the position information has not been updated, the process proceeds to step S24.

  [Step S22] If the position information of the host vehicle has been updated, it is determined whether the received data is stored in the reception buffer. If not saved, the process proceeds to step S24.

[Step S23] The reception data information (460a, 460b) is updated based on the reception data stored in the reception buffer.
[Step S24] The position of the host vehicle is displayed on the map based on the position information of the host vehicle. Further, based on the message stored in the received data information (460a, 460b) and the other vehicle (information), the position of the other vehicle is displayed on the map and the message is displayed. In the normal mode, nothing is set in the received data information (460a, 460b), so only the position of the host vehicle is displayed on the map. In the emergency response mode, if the host vehicle is in the real-time communication range or short-term communication range, information data to be stored in the received data information (460a, 460b) is sent, so a display based on this information is displayed. Perform together.

[Step S25] It is determined whether an emergency deployment cancellation notice has been received. If not received, the process proceeds to step S28.
[Step S26] When an emergency deployment cancellation notification is received, a message “Tight Release” is displayed on the display screen.

[Step S27] Since the emergency response mode ends, the data of the received data information (460a, 460b) is deleted.
[Step S28] It is determined whether or not to terminate the on-vehicle terminal system. When not ending, it returns to Step S21 and repeats processing. If it is to be terminated, the process is terminated.

  By performing the above processing procedure, the vehicle-mounted terminal 200 displays a message for display from the vehicle management device 100 when displaying the position of the host vehicle on a map based on the position information detected by the GPS 206 of the host vehicle. If the position information of the other vehicle is received, the position and message of the other vehicle are displayed on the position display of the own vehicle. Thus, the vehicle-mounted terminal 200 can display the position of another vehicle without executing complicated processing.

  The above processing functions can be realized by a computer. In that case, a program describing the processing contents of the functions that the mobile management device and the mobile terminal device should have is provided. By executing the program on a computer, the above processing functions are realized on the computer. The program describing the processing contents can be recorded on a computer-readable recording medium. Examples of the computer-readable recording medium include a magnetic recording device, an optical disk, a magneto-optical recording medium, and a semiconductor memory. Examples of the magnetic recording device include a hard disk device (HDD), a flexible disk (FD), and a magnetic tape. Examples of the optical disc include a DVD (Digital Versatile Disc), a DVD-RAM (Random Access Memory), a CD-ROM (Compact Disc Read Only Memory), and a CD-R (Recordable) / RW (ReWritable). Magneto-optical recording media include MO (Magneto-Optical disk).

  When distributing the program, for example, portable recording media such as a DVD and a CD-ROM in which the program is recorded are sold. It is also possible to store the program in a storage device of a server computer and transfer the program from the server computer to another computer via a network.

  The computer that executes the program stores, for example, the program recorded on the portable recording medium or the program transferred from the server computer in its own storage device. Then, the computer reads the program from its own storage device and executes processing according to the program. The computer can also read the program directly from the portable recording medium and execute processing according to the program. Further, each time the program is transferred from the server computer, the computer can sequentially execute processing according to the received program.
