Description

  The present invention relates to a crossing emergency notification system, a terminal device, a crossing emergency notification method, and a program.

Several techniques for improving safety at level crossings have been proposed.
For example, in the railroad crossing control system described in Patent Document 1, train information is transmitted from the vehicle upper side to the ground side. On the ground side, the level crossing is controlled based on the received train information (particularly, whether the vehicle passes or stops at the station before the level crossing). Furthermore, the ground side transmits the train information received from the vehicle upper side to the vehicle upper side. On the vehicle upper side, when the transmitted train information does not match the received train information, emergency stop control is performed.
In the level crossing control system described in Patent Document 1, this makes it possible to make an emergency stop at an early stage when the system is abnormal, and in this respect, safety at the level crossing can be improved.

Hereinafter, although embodiment of this invention is described, the following embodiment does not limit the invention concerning a claim. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.
FIG. 1 is a schematic block diagram showing a functional configuration of a railroad crossing emergency notification system according to an embodiment of the present invention. As shown in the figure, the crossing emergency notification system 1 includes a terminal device 100, an access point device 210, a router device 220, a crossing information server device 300, a crossing controller 400, and a special signal light emitter 500. Prepare. The railroad crossing controller 400 includes a relay (PBR) 410 and a relay (ERPR) 420.

  The level crossing emergency notification system 1 is a system for notifying an abnormality in a level crossing. In particular, the railroad crossing emergency notification system 1 detects an abnormality in the railroad crossing based on a user operation on the terminal device 100, and notifies the railcar driver of the abnormality. The rail vehicle here may be a train or a one-car train. Hereinafter, the driver of the railway vehicle is simply referred to as a driver.

The terminal device 100 is a portable terminal device. When the terminal device 100 receives an emergency notification operation, the terminal device 100 transmits an emergency notification signal. Here, the emergency notification operation is a user operation for notifying an abnormality in a level crossing. The emergency notification signal is a signal for notifying an abnormality in the level crossing.
Hereinafter, a case where the small tablet terminal device operates as the terminal device 100 dedicated to the level crossing emergency notification system 1 after receiving the installation of the application program (Application Program) will be described as an example. By operating the terminal device 100 as a terminal dedicated to the level crossing emergency notification system 1, the resources of the small tablet terminal device can be reserved exclusively for the function as the terminal of the level crossing emergency notification system 1. In this regard, the terminal device 100 can promptly transmit an emergency notification signal when receiving an emergency notification operation. Hereinafter, an application program for operating a device such as a small tablet terminal device as a terminal device for the crossing emergency notification system 1 is referred to as this application. Hereinafter, the application program is referred to as an application.

However, the terminal device 100 may be realized as a function in a general-purpose terminal device. For example, a smartphone may function as the terminal device 100 upon receiving an application program download.
Alternatively, the function as the terminal device 100 may be configured by hardware, such as the terminal device 100 including an ASIC (Application Specific Integrated Circuit).

The access point device 210 relays communication between the terminal device 100 and the crossing information server device 300. In particular, the access point device 210 performs wireless communication with the terminal device 100. When the emergency notification signal is received from the terminal device 100, the access point device 210 transmits (transfers) the received emergency notification signal to the crossing information server device 300.
The number of access point devices 210 included in the railroad crossing emergency notification system 1 is not limited to four as shown in FIG. 1, and it is sufficient that the terminal device 100 can identify the position of the terminal device 100 itself. For example, when the terminal device 100 specifies the positional relationship between the terminal device 100 itself and the level crossing only by a method other than communication with the access point device 210, the access point device 210 can communicate with the terminal device 100. Good. In this case, the number of access point devices 210 provided in the railroad crossing emergency notification system 1 may be one or more.

  The router device 220 relays communication between the access point device 210 and the crossing information server device 300. Thereby, the router device 220 connects the communication path between the terminal device 100 and the access point apparatus 210 and the communication path between the access point apparatus 210 and the crossing information server apparatus 300. The router device 220 may be configured integrally with any of the access point devices 210. That is, any of the access point devices 210 may be configured as an access point device with a router function. Alternatively, the router device 220 may be configured as a device different from the access point device 210.

  When the railroad crossing information server device 300 receives the emergency notification signal from the terminal device 100, the crossing information server device 300 operates (emits light) the special signal light emitter 500 based on the received emergency notification signal. By operating the special signal light emitter 500, the crossing emergency notification system 1 notifies the driver of an abnormality in the crossing. The crossing information server apparatus 300 is configured using a computer.

The level crossing controller 400 controls each device provided in connection with the level crossing such as the special signal light emitter 500.
The relay (ERPR) 420 switches the presence / absence of the operation of the special signal light emitter 500. Specifically, the relay (ERPR) 420 functions as a switch that switches whether the special signal light emitter 500 emits light. The relay (ERPR) 420 is provided in a fail safe, and causes the special signal light emitter 500 to emit light when it is dropped, and stops light emission of the special signal light emitter 500 when it is lifted.
The relay (PBR) 410 is a relay that operates the relay (ERPR) 420. The relay (PBR) 410 is provided to drop the relay (ERPR) 420 when the relay (PBR) 410 itself is dropped.

When the access point device 210 receives from the terminal device 100 an emergency notification signal for notifying an abnormality in a level crossing, the special signal light emitter 500 outputs an alarm indicating the abnormality in the level crossing. The special signal light emitter 500 emits light to notify the driver of an abnormality in the crossing.
However, as a method for the railroad crossing emergency notification system 1 to notify the driver of an abnormality in the railroad crossing, not only the method in which the special signal light emitter 500 emits light but also various methods can be used. For example, the railroad crossing emergency notification system 1 may display a message notifying the abnormality on a display device provided on the driver's seat or the side of the track. Alternatively, the railroad crossing emergency notification system 1 may output a warning sound to a speaker provided in the driver's seat.
Hereinafter, the level crossing area is also referred to as a level crossing road. Therefore, the inside of a level crossing is also referred to as the inside of a level crossing, and the outside of a level crossing is also referred to as outside of a level crossing.

FIG. 2 is an explanatory diagram illustrating an arrangement example of the access point device 210. The X coordinate shown in the figure indicates the direction of the line, and the Y coordinate indicates a direction orthogonal to the direction of the line. In the example of FIG. 2, four access point devices 210 are provided at one level crossing. One access point device 210 is provided at each of the four corners of the railroad crossing.
The emergency notification area A11 is an area where the terminal device 100 receives an emergency notification operation.

The emergency notification area A11 is determined according to the level crossing position. In the following, a case where an area in a railroad crossing is set as an emergency notification area A11 will be described as an example. However, the setting of the emergency notification area A11 is not limited to the setting that matches the area in the railroad crossing. For example, the emergency notification area A11 is not limited to the area in the railroad crossing but may include the surrounding area. In this case, a user who has witnessed an abnormality in the railway crossing near the railway crossing can operate the terminal device 100 to notify the abnormality in the railway crossing. The user here is a user of the terminal device 100.
The surrounding area A12 is an area provided around the emergency notification area A11. The surrounding area A12 is set as an area where the terminal device 100 itself detects that the terminal device 100 is located near the railroad crossing.

Next, with reference to FIG. 3, the flow of the procedure for using the terminal device 100 will be described.
FIG. 3 is an explanatory diagram illustrating an example of a procedure flow for using the terminal device 100. In the figure, the flow of the procedure is shown as a flowchart.
A person who wishes to use the terminal device 100 registers information such as an address and a name in a public organization (step S1), and then receives the terminal device 100 (step S2). The public organization here may be a railway operator, an administrative organization such as a municipality or a prefecture, or a trustee entrusted by a railway operator or an administrative organization. Also good.
However, the distribution method of the terminal device 100 is not limited to a method by a public organization or the like, and various methods can be used. From the viewpoint of preventing unauthorized use such as mischief, it is preferable to distribute the terminal device 100 by a method that can identify the user.

  The terminal device 100 is given a terminal ID (Identifier) for identifying the terminal device 100. When transmitting the emergency notification signal, the terminal device 100 transmits the emergency notification signal including the terminal ID. Thereby, the administrator of the railroad crossing emergency notification system 1 can identify the terminal device 100 of the transmission source based on the terminal ID. Furthermore, the administrator of the level crossing emergency notification system 1 can specify the owner of the terminal device 100 based on the information registered in step S1. Thus, the deterrent effect with respect to the abuse of the terminal device 100 is expected by identifying the owner of the terminal device 100 that has transmitted the emergency notification signal.

  Further, the terminal device 100 stores information on railroad crossings in advance. Here, as the crossing information, for example, the positional relationship between the terminal device 100 and the crossing, such as the position of the access point device 210 installed at the crossing, the total length of the crossing, the full width of the crossing, and an estimation formula for estimating the position of the crossing. The information used for the estimation is stored in the terminal device 100 in advance. Further, information to be displayed by the terminal device 100 such as a name of a crossing is stored in the terminal device 100 in advance. However, information for the terminal device 100 to display is not essential.

  When there is a change in the level crossing targeted by the level crossing emergency notification system 1 (step S3: YES), the owner of the terminal device 100 receives an update of the level crossing information registered in the terminal device 100 (step S4). . As an example of a change in the level crossing targeted by the level crossing emergency notification system 1, when a new level crossing is established, when an existing level crossing is newly targeted by the level crossing emergency notification system 1, and when a level crossing emergency occurs A case where the level crossing targeted by the notification system 1 is abolished.

  The owner of the terminal device 100 receives an update notification by postcard or e-mail from a public institution, for example. Various methods can be used as a method for the owner (user) of the terminal device 100 to update the information on the crossing registered in the terminal device 100. For example, the owner of the terminal device 100 may update through the Internet, such as downloading an update program from the Internet. Alternatively, the owner of the terminal device 100 may bring the terminal device 100 into a public institution or the like. Alternatively, the terminal device 100 may update the information through communication with the access point device 210.

  Further, an expiration date is set in this application in order to reduce the possibility of misuse or malfunction of the terminal device 100. When the expiration date approaches (step S5: YES), the owner of the terminal device 100 can continue to use the terminal device 100 after receiving the extension of the time limit (step S6). Hereinafter, the expiration date of this application is also referred to as the expiration date of the terminal device 100.

Here, when the terminal device 100 is stolen, it is difficult to identify an operator even if an emergency notification operation is performed on the terminal device 100, and deterrence against misuse such as mischief does not work. In this respect, there is a relatively high possibility that the stolen terminal device 100 is misused. Even if the owner of the terminal device 100 leaves the terminal device 100 unnecessary and left unattended, the left terminal device 100 may be misused.
Therefore, by setting an expiration date for the function of the terminal device 100 transmitting the emergency notification signal, it is possible to avoid abuse after the expiration of the expiration date. When a legitimate holder uses the terminal device 100, the terminal device 100 can continue to be used after the expiration date is extended as in step S6.

In addition, when there is a change in the crossing targeted by the crossing emergency notification system 1, if the crossing information registered in the terminal device 100 is not updated, the terminal device 100 may not operate correctly. For example, when an existing level crossing becomes a new target of the level crossing emergency notification system 1, the terminal device 100 cannot detect an emergency notification area of this level crossing unless information on the level crossing is registered in the terminal device 100. Thereby, the terminal device 100 does not execute a function of receiving an emergency notification operation and transmitting an emergency notification signal.
Therefore, in addition to the process of extending the expiration date of the terminal apparatus 100, the process of updating the level crossing information registered in the terminal apparatus 100 is performed. As a result, the terminal device 100 operates correctly even at a level crossing newly targeted for the level crossing emergency notification system 1.

Next, with reference to FIG.4 and FIG.5, the function structure of the terminal device 100 and the crossing information server apparatus 300 is demonstrated.
FIG. 4 is a schematic block diagram illustrating a functional configuration of the terminal device 100. As shown in the figure, the terminal device 100 includes a first communication unit 110, a display unit 120, an operation input unit 130, a first storage unit 180, and a first control unit 190. The first control unit 190 includes an expiration date processing unit 191, a terminal position determination unit 192, and an emergency notification processing unit 193. The emergency notification processing unit 193 includes a transmission processing unit 194 and a post-transmission period processing unit 195.

The first communication unit 110 communicates with the access point device 210 wirelessly. The first communication unit 110 corresponds to an example of an emergency notification signal transmission unit. When the display unit 120 displays an emergency notification operation screen and an emergency notification operation is performed by the operation input unit 130, an emergency notification is performed. Send a signal.
Here, the emergency notification operation screen is a screen indicating that the terminal device 100 is in a state of receiving an emergency notification operation. As described above, the emergency notification operation is a user operation for notifying an abnormality in a level crossing. In the following, an example will be described in which the emergency notification operation is an operation of long pressing the display screen displaying the emergency notification operation screen. However, the emergency notification operation is not limited to this. From the viewpoint of preventing malfunction, it is preferable that an operation with a relatively low possibility of being detected accidentally, such as a long press on the screen, a tap more than a predetermined number of times, or a flick operation, be an emergency notification operation.
Alternatively, the terminal device 100 may be provided with a push button for an emergency notification operation, and an emergency notification operation may be received by pressing the push button. In this case, in order to reduce the possibility of erroneous operation of the push button, an open / close type cover may be provided on the push button. Alternatively, an operation of continuing to press the push button for 3 seconds or more may be an emergency notification operation, and the erroneous operation may be reduced by a push button pressing method.
Alternatively, the terminal device 100 may be provided with a string, and an operation of pulling the string like an operation of a security buzzer may be detected as an emergency notification operation.

  The display unit 120 includes a display screen such as a liquid crystal panel, and displays various images. In particular, the display unit 120 displays an image corresponding to the state of the terminal device 100. For example, when the terminal position determination unit 192 determines that the terminal device 100 is located in the emergency notification area A11 (FIG. 2), the display unit 120 displays an emergency notification operation screen. The display unit 120 corresponds to an example of a notification unit. The emergency notification operation screen displayed by the display unit 120 corresponds to an example of notification that the terminal device 100 is in a state of receiving an emergency notification operation.

However, the method of notifying the user that the terminal device 100 is in a state of receiving the emergency notification operation is not limited to the method of displaying the emergency notification operation screen. For example, the terminal device 100 may notify by light whether or not the terminal device 100 is in a state of receiving an emergency notification operation, such as turning on a light of a different color depending on the state of the terminal device 100 itself.
Alternatively, the terminal device 100 may notify whether the terminal device 100 is in a state of receiving an emergency notification operation, such as vibrating the terminal device 100 itself with a different vibration pattern depending on the terminal device 100 itself. Good.

  The operation input unit 130 includes an input device such as a touch sensor provided on the display screen of the display unit 120 and constituting a touch panel, for example, and receives a user operation. In particular, the operation input unit 130 accepts an emergency notification operation while the display unit 120 displays an emergency notification operation screen. However, the configuration of the operation input unit 130 is not limited to a configuration including a touch sensor, and may be a configuration capable of receiving an emergency notification operation. For example, as described above, the operation input unit 130 may include a push button for an emergency notification operation, and the emergency notification operation may be received by pressing the push button. Alternatively, the operation input unit 130 may be provided with a string, and an emergency notification operation may be received by an operation of pulling the string.

The 1st memory | storage part 180 is comprised including the memory | storage device with which the terminal device 100 is provided, and memorize | stores various information.
The first control unit 190 controls each unit of the terminal device 100 and executes various functions. The first control unit 190 is configured by, for example, a CPU (Central Processing Unit) provided in the terminal device 100 reading out and executing a program from the first storage unit 180.

  The expiration date processing unit 191 determines whether the function of the terminal device 100 transmitting the emergency notification signal is within the expiration date. Specifically, the expiration date processing unit 191 determines whether or not this application is within the expiration date. When it is determined that the expiration date has passed, the expiration date processing unit 191 suppresses the transmission of the emergency notification signal by the first communication unit 110. Specifically, the expiration date processing unit 191 suppresses the transmission of the emergency notification signal by the first communication unit 110 by stopping the operation of the terminal device 100.

  The terminal position determination unit 192 determines the positional relationship between the railroad crossing and the terminal device 100. In particular, the terminal position determination unit 192 determines whether the terminal device 100 is located in the emergency notification area A11 and whether it is located in the surrounding area A12. The terminal position determination unit 192 determines the positional relationship between the railroad crossing and the terminal device 100 based on, for example, the positioning result of the terminal device 100 by GNSS (Global Navigation Satellite System) and the radio wave intensity from the access point device 210. judge.

The emergency notification processing unit 193 performs processing related to transmission of an emergency notification signal.
The transmission processing unit 194 performs processing for transmitting an emergency notification signal. In particular, the transmission processing unit 194 displays an emergency notification operation screen on the display unit 120 and causes the first communication unit 110 to transmit an emergency notification signal when the operation input unit 130 receives an emergency notification operation.

  When the first communication unit 110 transmits an emergency notification signal, the post-transmission period processing unit 195 suppresses transmission of a new emergency notification signal for a predetermined period from the occurrence of a predetermined event related to the transmission of the emergency notification signal. Thereby, it is possible to prevent a person who abuses the terminal device 100 from continuously misusing the terminal device 100, such as transmitting an emergency notification signal at a plurality of adjacent railroad crossings.

  Hereinafter, a case will be described as an example in which the post-transmission period processing unit 195 suppresses transmission of a new emergency notification signal for a certain time after confirming that the relay (ERPR) 420 is dropped. However, the post-transmission period processing unit 195 performs emergency notification based on an event other than the confirmation of the fall of the relay (ERPR) 420, such as suppressing transmission of a new emergency notification signal for a certain period of time after starting transmission of the emergency notification signal. You may make it suppress transmission of a signal.

FIG. 5 is a schematic block diagram illustrating a functional configuration of the railroad crossing information server device 300. As shown in the drawing, the crossing information server device 300 includes a second communication unit 310, a second storage unit 380, and a second control unit 390. The second control unit 390 includes a terminal processing unit 391 and a notification processing unit 392.
The second communication unit 310 communicates with the terminal device 100 via the access point device 210 and the router device 220. In particular, the second communication unit 310 receives an emergency notification signal transmitted from the terminal device 100. The second communication unit 310 communicates with the crossing controller 400. In particular, the second communication unit 310 transmits a relay control signal for the relay (PBR) 410. The reception of the emergency notification signal and the transmission of the relay control signal by the second communication unit 310 may be performed using separate circuits, or may be performed using the same circuit.

The 2nd memory | storage part 380 is comprised including the storage device with which a crossing information server apparatus 300 is provided, and memorize | stores various information.
The second control unit 390 controls each part of the crossing information server device 300 to execute various functions. The second control unit 390 is configured by, for example, a CPU included in the crossing information server device 300 reading and executing a program from the second storage unit 380.

The terminal processing unit 391 performs processing related to communication with the terminal device 100. In particular, the terminal processing unit 391 receives data from the terminal device 100 and records a log related to communication with the terminal device 100.
The notification processing unit 392 performs processing when the second communication unit 310 receives an emergency notification signal. In particular, when the second communication unit 310 receives an emergency notification signal, the notification processing unit 392 performs control to drop the relay (PBR) 410.

Next, state transition of the terminal device 100 will be described with reference to FIGS.
FIG. 6 is a state transition diagram illustrating state transition of the terminal device 100. As shown in the figure, the state of the terminal device 100 includes a stop state S11, a level crossing searching state S12, a level crossing approaching state S13, a level crossing in-road state S14, an emergency notification state S15, and an emergency notification completion state S16. .

The stop state S11 is a state in which this application is not activated. When this application is started in the stop state S11, the state transits to the level crossing searching state S12.
Note that this application may be automatically started when the terminal device 100 is connected to the power source (ON). Alternatively, the application may be activated based on a user operation that instructs activation of the application.

The level crossing searching state S12 is a state in which the terminal position determination unit 192 has not detected a level crossing. Specifically, the level crossing searching state S12 is a state in which the terminal position determination unit 192 determines that the first communication unit 110 has not received a wireless signal from the access point device 210.
When the terminal position determination unit 192 determines that the terminal device 100 is located in the surrounding area A12 in the level crossing searching state S12, the state transitions to the level crossing approaching state S13. When the terminal position determination unit 192 determines that the terminal device 100 is located in the emergency notification area A11 in the level crossing searching state S12, the state transitions to the level crossing state S14.

The level crossing approaching state S13 is a state in which the terminal device 100 is located outside the level crossing and near the level crossing. Specifically, the level crossing approaching state S13 is a state in which the terminal position determination unit 192 determines that the terminal device 100 is located in the surrounding area A12.
When the terminal position determination unit 192 determines that the first communication unit 110 has not received a wireless signal from the access point device 210 in the level crossing approaching state S13, the state transitions to the level crossing searching state S12. When the terminal position determination unit 192 determines that the terminal device 100 is located in the emergency notification area A11 in the level crossing approaching state S13, the state transitions to the level crossing state S14.

The level crossing state S14 is a state in which the terminal device 100 has entered the level crossing and the emergency notification function is operable. Specifically, the railroad crossing state S14 is a state in which the terminal position determination unit 192 determines that the terminal device 100 is located in the emergency notification area A11.
When the terminal position determination unit 192 determines that the first communication unit 110 has not received the wireless signal from the access point device 210 in the level crossing state S14, the state transitions to the level crossing searching state S12. When the terminal position determination unit 192 determines that the terminal device 100 is located in the surrounding area A12 in the level crossing state S14, the state transitions to the level crossing approaching state S13. When the operation input unit 130 detects an emergency notification operation in the level crossing state S14, the state transits to the emergency notification state S15.
Note that even when the power of the terminal device 100 is cut off, the stop state S11 is entered. Examples of the power-off of the terminal device 100 include a case where the battery has run out or the terminal device 100 is a tablet terminal device or a smartphone and a power-off operation is performed. In addition, even when the terminal device 100 expires, the stop state S11 is entered.

The emergency notification state S15 is a state in which the first communication unit 110 transmits a signal for dropping the relay (PBR) 410.
When the first communication unit 110 receives a signal indicating the drop of the relay (ERPR) 420 in the emergency notification state S15, the state transitions to the emergency notification completion state S16.

The emergency notification completion state S16 is a state where the emergency notification is completed. More specifically, the emergency notification completion state S16 is a state in which the relay (ERPR) 420 is confirmed to be dropped in the emergency notification state S15.
When a certain period of time has elapsed since the transition to the emergency notification completion state, the state transitions to the level crossing searching state S12.

FIG. 7 is an explanatory diagram showing a display example of the display unit 120 in the level crossing searching state S12. In the level crossing searching state S12, the display unit 120 displays that there is no level crossing nearby.
FIG. 8 is an explanatory diagram illustrating a display example of the display unit 120 in the crossing approaching state S13.

FIG. 9 is an explanatory diagram illustrating a display example of the display unit 120 in the railroad crossing state S14. In the level crossing state S14, the display unit 120 displays an emergency button screen. In a state where the display unit 120 displays the emergency button screen, the operation input unit 130 receives an emergency notification operation by a long press operation on the screen. The emergency button screen corresponds to an example of an emergency notification operation screen.
FIG. 10 is an explanatory diagram illustrating a display example of the display unit 120 in the emergency notification state S15. In the emergency notification state S15, the display unit 120 displays that an emergency notification is being performed. In addition, the display unit 120 displays a message prompting the user's safety such as “Please leave the railroad crossing”.

  FIG. 11 is an explanatory diagram illustrating a display example of the display unit 120 when a communication error occurs in the emergency notification state S15. When a communication error occurs in the emergency notification state S15, a message prompting the user to perform another operation is displayed. Further, a confirmation push button is displayed to confirm that the user has recognized the communication error.

Next, the operation of the railroad crossing emergency notification system 1 will be described with reference to FIGS.
12 to 13 are explanatory diagrams illustrating an example of an operation procedure of the terminal device 100.
12 to 13, the expiration date processing unit 191 performs an expiration date determination process (step S101). Specifically, the expiration date processing unit 191 determines whether or not it is within the expiration date set for this application. Note that the next expiration date determination may be omitted for a certain period after the expiration date processing unit 191 determines the expiration date. For example, when the expiration date determination process of step S101 is executed twice or more on the same day, in the second and subsequent expiration date determination processes, the expiration date processing unit 191 may unconditionally determine that it is within the expiration date. .

When it is determined that the expiration date has passed (step S101: expiration date), the expiration date processing unit 191 disables the application (step S111). For example, the expiration date processing unit 191 displays a message prompting registration for extension of the expiration date and locks the terminal device 100. The lock of the terminal device 100 here means that the application cannot be started.
After step S111, the processes in FIGS. 12 to 13 are terminated. The state in which the processes in FIGS. 12 to 13 are completed corresponds to the stop state S11.

  On the other hand, when it determines with it being within an expiration date by step S101 (step S101: within an expiration date), the 1st control part 190 performs an emergency notification state determination process (step S121). Specifically, the first control unit 190 determines whether the state of the terminal device 100 corresponds to an emergency notification completion state before a certain time elapses or an emergency notification completion state after a certain time elapses other than the emergency notification completion state. judge. The elapsed time here is the elapsed time from the completion of the emergency notification.

When it is determined that the emergency notification is completed and before a certain time has elapsed (step S121: the emergency notification is completed and before the time has elapsed), the post-transmission period processing unit 195 controls the display unit 120 to display the emergency notification completion screen. Transmission is stopped (step S131). If transmission has already been stopped, the post-transmission period processing unit 195 continues to stop transmission.
The emergency notification completion screen here is a screen indicating that the emergency notification shown on the display screen of FIG. 10 has been completed. The display unit 120 does not display the emergency notification completion screen, but displays the level crossing searching screen (screen in FIG. 7), the level crossing approaching screen (screen in FIG. 8), or the emergency notification operation screen as it is. May be.
The post-transmission period processing unit 195 suppresses continuous misuse of the terminal device 100, such as transmitting an emergency notification signal at a plurality of adjacent level crossings by stopping transmission for a certain time after the completion of the emergency notification. Can do.
After step S131, the process returns to step S121.

On the other hand, if it is determined in step S121 that the state is other than the emergency notification completion state (step S121: other than the emergency notification completion state), the process proceeds to step S142 described later.
On the other hand, if it is determined in step S121 that the emergency notification has been completed and a certain time has elapsed (step S121: the emergency notification has been completed and the time has elapsed), the post-transmission period processing unit 195 cancels the emergency button non-operation (step S141). ). Specifically, by completing the emergency notification completion state and the loop before the elapse of time, it is possible to transit to step S171 for displaying the emergency notification operation screen in the emergency notification area A11.

After step S141, the terminal position determination unit 192 performs position determination (position estimation) of the terminal device 100 (step S142).
And the terminal position determination part 192 performs a railroad crossing road inside / outside determination process based on the position determined by step S142 (step S143). In the level crossing road inside / outside determination process, the terminal position determination unit 192 determines whether the position of the terminal device 100 is located outside the surrounding area A12, inside the surrounding area A12, outside the emergency notification area A11, or inside the emergency notification area A11. To do.
Note that the terminal position determination unit 192 determines the position of the terminal device 100 within the surrounding area A12 when the terminal apparatus 100 continues to be located within the surrounding area A12 for a certain period of time. On the other hand, the terminal position determination unit 192 determines that the position of the terminal device 100 is out of the surrounding area A12 before a predetermined time has elapsed since the terminal apparatus 100 started to be positioned in the surrounding area A12.

When it is determined that the terminal device 100 is located outside the surrounding area A12 (step S143: outside A12), the terminal position determination unit 192 causes the display unit 120 to display a level crossing searching screen (screen in FIG. 7) (step S151). .
After step S151, the process proceeds to step S101.

On the other hand, when it is determined that the terminal device 100 is located in the surrounding area A12 and outside the emergency notification area A11 (step S143: inside A12 and outside A11), the terminal position determination unit 192 displays a crossing approaching screen (screen in FIG. 8). Is displayed on the display unit 120 (step S161).
After step S161, the process proceeds to step S101.

  On the other hand, when it is determined in step S143 that the terminal device 100 is located in the emergency notification area A11 (step S143: in A11), the transmission processing unit 194 displays an emergency button screen (screen in FIG. 9) on the display unit 120. (Step S171). In the example of FIGS. 12 to 13, when the terminal position determination unit 192 determines that the terminal device 100 is located in the railroad crossing once, the terminal position determination unit 192 transitions to the railroad crossing road state S <b> 14. On the other hand, when the terminal position determination unit 192 determines that the terminal device 100 is located in the railroad crossing a plurality of times, the terminal position determination unit 192 may transit to the railroad crossing road state S14. Alternatively, the terminal position determination unit 192 may be in the railroad crossing state S14 only within a predetermined time after determining that the terminal device 100 is located in the railroad crossing.

  After step S171, the transmission processing unit 194 performs emergency notification processing (step S201). In the emergency notification process, the transmission processing unit 194 determines whether or not the operation input unit 130 has received a long press on the emergency button screen. If the transmission processing unit 194 determines that the long press has been received, the transmission processing unit 194 controls the first communication unit 110. An emergency notification signal is transmitted to the crossing information server device 300. When the emergency communication signal is transmitted to the crossing information server device 300 by controlling the first communication unit 110, the transmission processing unit 194 determines whether or not the emergency notification is completed based on a response from the crossing information server device 300. judge. Specifically, the transmission processing unit 194 determines whether or not an emergency notification completion signal has been received from the crossing information server device 300.

If it is determined in step S201 that the emergency button screen has not been long pressed (step S201: not long pressed), the process returns to step S101.
On the other hand, when it is determined in step S201 that the emergency notification has been completed (step S201: emergency notification is completed), the transmission processing unit 194 deactivates the emergency button for the terminal device 100 (step S211). For example, the transmission processing unit 194 causes the display unit 120 to display a message indicating that the emergency button screen is not displayed, and suppresses the display of the emergency button screen.
Step S201: The state of YES corresponds to the emergency notification completion state S16.
After step S211, the process returns to step S101.

On the other hand, when it is determined in step S201 that the emergency notification completion signal has not been received (step S302: communication failure), the transmission processing unit 194 performs error processing (step S221). In the error processing, the transmission processing unit 194 displays an error screen (the screen of FIG. 11) on the display unit 120 and waits for an error confirmation operation (a user operation indicating that the error screen has been confirmed) to be performed. When the error checking operation is performed, the transmission processing unit 194 ends the display of the error screen. The transmission processing unit 194 performs error processing when the communication failure is repeated a predetermined number of times or more, and does not perform processing such as displaying an error screen in step S221 until the communication failure reaches the predetermined number (through). You may do it.
After step S221, the process returns to step S101.

FIG. 14 is a flowchart illustrating an example of an operation procedure of the crossing information server device 300. When the crossing information server device 300 detects that the terminal device 100 is located within the communication range of any of the access point devices 210, the crossing information server device 300 performs the processing shown in FIG.
In the process of FIG. 14, the terminal processing unit 391 performs a terminal communication determination process (step S501). In the terminal communication determination process, the terminal processing unit 391 controls the second communication unit 310 to perform communication with the terminal device 100 and acquire (receive) data from the terminal device 100. In particular, the terminal processing unit 391 acquires information indicating the access point device 210 with which the terminal device 100 has successfully communicated and identification information of the terminal device 100 from the terminal device 100, and stores the identification information of the terminal device 100 in the second storage unit. Store in 380. Hereinafter, the identification information of the terminal device 100 is referred to as a terminal ID.

  When the communication with the terminal device 100 is disconnected, such as when the terminal device 100 goes out of the communication range of the access point device 210, the second control unit 390 ends the processing of FIG. Even when the access point device 210 with which the terminal device 100 has successfully communicated is not registered, the second control unit 390 ends the processing of FIG.

Next, the notification processing unit 392 determines whether or not the second communication unit 310 has received an emergency notification signal from the terminal device 100 via the access point device 210 (step S502). If it is determined that the emergency notification signal has not been received (step S502: NO), the process returns to step S502. That is, the notification processing unit 392 waits for an emergency notification signal from the terminal device 100.
On the other hand, when it determines with having received the emergency notification signal (step S502: YES), the notification process part 392 performs a special signal light emitter operation process (step S503). In the special signal light emitter operation process, the notification processing unit 392 operates the special signal light emitter 500 by controlling the second communication unit 310 to transmit the PBR fall signal to the level crossing controller 400, and generates the ERPR fall confirmation signal. Then, the operation of the special signal light emitter 500 is confirmed.
Here, the PBR drop signal is a signal for dropping the relay (PBR) 410. The ERPR drop confirmation signal is a signal indicating the position of the relay (ERPR) 420 (whether it is the upper side or the lower side).
The notification processing unit 392 causes the second communication unit 310 to transmit the PBR drop signal to the railroad crossing control device 400 until the ERPR drop confirmation signal is on the drop side.

Next, the notification processing unit 392 controls the second communication unit 310 to transmit an emergency notification completion signal to the terminal device 100 via the access point device 210 (step S504). For example, the notification processing unit 392 controls the second communication unit 310 to repeat the transmission of the emergency notification completion signal to the terminal device 100 s times (s is a positive integer).
After step S504, the process in FIG.

As described above, the terminal position determination unit 192 determines whether or not the terminal device 100 is located within the emergency notification area determined according to the level crossing position. Further, when the terminal position determination unit 192 determines that the terminal device 100 is located in the emergency notification area, the display unit 120 displays an emergency notification operation screen indicating that the terminal device 100 is in a state of receiving an emergency notification operation. The first communication unit 110 transmits an emergency notification signal when the display unit 120 displays the emergency notification operation screen and an emergency notification operation is performed.
As a result, the user of the terminal device 100 can notify the terminal device 100 of a level crossing abnormality. Therefore, when danger occurs at a railroad crossing, the train can be informed of the danger as soon as possible even if the reporter (the person who intends to report) cannot move quickly.

  In addition, since the area where the display unit 120 displays the emergency notification operation screen is limited to the emergency notification area determined according to the position of the level crossing, the level crossing using the terminal device 100 is performed outside the emergency notification area. Abnormality notification is not performed. In this respect, the possibility of erroneous operation and the possibility of misuse of the terminal device 100 can be reduced.

Further, the post-transmission period processing unit 195 suppresses the transmission of a new emergency notification signal for a predetermined period from the occurrence of a predetermined event related to the transmission of the emergency notification signal when the first communication unit 110 transmits the emergency notification signal. To do.
Thereby, it is possible to prevent a person who abuses the terminal device 100 from continuously misusing the terminal device 100, such as transmitting an emergency notification signal at a plurality of adjacent railroad crossings.

The expiration date processing unit 191 determines whether or not the function for transmitting the emergency notification signal is within the expiration date, and suppresses the transmission of the emergency notification signal when it is determined that the expiration date has passed.
Here, when the terminal device 100 is stolen, it is difficult to identify an operator even if an emergency notification operation is performed on the terminal device 100, and deterrence against misuse such as mischief does not work. In this respect, there is a relatively high possibility that the stolen terminal device 100 is misused. Even if the owner of the terminal device 100 leaves the terminal device 100 unnecessary and left unattended, the left terminal device 100 may be misused.
Therefore, by setting an expiration date for the function of the terminal device 100 transmitting the emergency notification signal, it is possible to avoid abuse after the expiration of the expiration date. When a legitimate holder uses the terminal device 100, the terminal device 100 can continue to be used after the expiration date is extended.

Further, in the railroad crossing emergency notification system 1, the special signal light emitter 500 is operated when there is a notification of an abnormality in the railroad crossing, but forcibly stopping the railway vehicle in consideration of the reliability of notification such as a user's erroneous operation. Do not do. The method of stopping the railway vehicle by the operation of the special signal light emitter 500 is the same method as the return handling of the current level crossing trouble notification device. For this reason, the level crossing emergency notification system 1 can be added to the current level crossing trouble notification device without the need to change the current system.
When the special signal light emitter 500 is turned on, the driver stops the railway vehicle, stops at the railroad crossing, and performs safety confirmation of the crossing and collects information from the operator. When the safety of the level crossing is confirmed, return handling is performed and the special signal light emitter that is operating is stopped.

  In addition, the condition of the position of the railway vehicle may be included in the condition for the state of the terminal device 100 to transit to the railroad crossing state S14. For example, only when the railway vehicle is approaching the railroad crossing where the terminal device 100 is located (for example, when the railway vehicle is located within a predetermined distance from the railroad crossing where the terminal device 100 is located). May display an emergency notification operation screen.

In the above description, the case where the terminal device 100 performs the process of suppressing the reception of the emergency notification operation for a predetermined time after the occurrence of the emergency notification event has been described as an example, but the crossing information server device 300 may suppress the process. Good. For example, the emergency notification signal from the same terminal device 100 may be ignored until a predetermined time has elapsed since the crossing information server device 300 received the emergency notification signal.
In addition, once the emergency notification operation is performed, the application may be stopped and a stop release operation may be received by a public institution or the like.

A program for realizing all or part of the functions of the first control unit 190 and the second control unit 390 is recorded on a computer-readable recording medium, and the program recorded on the recording medium is stored in a computer system. The processing of each unit may be performed by reading and executing. The “computer system” here includes an OS and hardware such as peripheral devices.
The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes design changes and the like without departing from the gist of the present invention.
