(Overview of Embodiment 1)
FIG. 3 is an explanatory diagram showing an overview of the first embodiment. In FIG. 3, a construction site 302 indicates where road construction is taking place, for example in a tunnel. At the construction site 302, for example, ready-mixed concrete is placed. The ready-mixed concrete used for the construction site 302 is kneaded at the factory 301 and transported by the vehicle 300 . Vehicles 300 (mixer trucks) for transporting ready-mixed concrete depart periodically from the factory 301 and arrive at the construction site 302 in sequence. Upon arrival at the construction site 302, ready-mixed concrete is handed over. Specifically, the ready-mixed concrete transported by the vehicle 300 is, for example, unloaded, pumped by a pump truck, and placed at the target position.

Here, the quality of ready-mixed concrete deteriorates after 90 minutes from the start of kneading. For this reason, ready-mixed concrete that has not passed 90 minutes from the start of kneading is used for placing. Ready-mixed concrete that has passed 90 minutes from the start of kneading may be discarded in some cases. Therefore, sufficient attention is paid to the management of ready-mixed concrete.

A plurality of areas (first area to fourth area) are provided on the route from the factory 301 to the construction site 302 . Vehicle 300 (position measuring device 30) appropriately transmits position information to second management server 10B. The second management server 10B transmits the position information received from the vehicle 300 to the first management server 10A. The first management server 10A uses the position information received from the second management server 10B to determine whether the vehicle 300 is within the area. When the first management server 10A determines that the vehicle 300 is within the area, it identifies a passage area through which the vehicle 300 passes. Here, the first management server 10A manages movement information corresponding to each area. The movement information is, for example, information indicating the movement status according to the area, such as "shipment", "passing through checkpoint", and "arrival".

Here, when the vehicle 300 passes through each area, the second management server 10B receives passage information including the time when the vehicle 300 passed through each area from the vehicle 300 (position measuring device 30). The second management server 10B registers the passing information received from the vehicle 300. FIG. The second management server 10B also transmits passage information received from the vehicle 300 to the first management server 10A. For example, the second management server 10B transmits transit information to the first management server 10A by e-mail.

When receiving the passage information from the second management server 10B, the first management server 10A registers the received passage information. For example, when the vehicle 300 passes through the first area, the first management server 10A and the second management server 10B register (store) the time when the vehicle 300 passed through the factory 301 (shipping time). Further, when the vehicle 300 passes through the second area and the third area, the first management server 10A and the second management server 10B register the time when the vehicle 300 passed through the A checkpoint and the B checkpoint, respectively. In addition, the first management server 10A and the second management server 10B register the arrival time (arrival time) at the construction site 302 when the vehicle 300 passes through the fourth area.

Also, the first management server 10A stores a message corresponding to each area. For example, a message such as "departure" is stored in association with the first area. Also, for example, a message such as "I will arrive soon" is stored in association with the fourth area. For example, when the vehicle 300 passes through the first area, the first management server 10A sends a message such as "departure" to the terminal device 20 (the person in charge of the construction site 302 possesses it) in response to a request from the terminal device 20. to the terminal device 20). In addition, when the vehicle 300 passes through the fourth area, the first management server 10A transmits to the terminal device 20 a message such as "We will be arriving soon." Similarly, when the vehicle 300 passes through the second area and the third area, messages associated with each area are transmitted to the terminal device 20 in response to requests from the terminal device 20 . The first management server 10A is not limited to transmitting these messages to the terminal device 20 in response to a request from the terminal device 20, and may automatically transmit to the terminal device 20 registered in advance.

The first management server 10A also manages construction status management information. The construction status management information is information including quality test data of ready-mixed concrete actually used at the construction site 302, weather data, and the like. The quality test data and weather data are transmitted from the terminal device 20 of the person in charge of the site or quality test. The first management server 10A also transmits construction status management information to the terminal device 20 in response to a request from the terminal device 20 . As a result, the terminal device 20 can receive the construction status management information managed by the first management server 10A and display the received construction status management information in a browsable manner.

(Example of processing for managing operation information of vehicle 300 performed by first management server 10A according to Embodiment 1)
FIG. 8 is a flowchart showing an example of a process of managing operation information of the vehicle 300 performed by the first management server 10A according to the first embodiment. In FIG. 8, the first management server 10A determines whether the vehicle 300 has passed through any area (step S101). In step S101, the first management server 10A receives, for example, the position information (information indicating the current location) from the vehicle 300 (position measuring device 30) via the second management server 10B, and the pre-stored area position information, it is determined whether the vehicle 300 is located in any area.

The first management server 10A waits until the vehicle 300 passes through any area (step S101: NO). When the vehicle 300 has passed through any area (step S101: YES), the first management server 10A identifies the vehicle 300 that has passed through the area (step S102). Specifically, in step S102, the first management server 10A matches the management number transmitted from the position measuring device 30 among the "management number" of the vehicle information 401 stored in the operation information management table of FIG. 5B.

The first management server 10A waits until receiving a transport information viewing request from the terminal device 20 (step S121: NO).

When the first management server 10A receives the transport information viewing request from the terminal device 20 (step S121: YES), the transport information (operation management information or construction status management information) corresponding to the request is transmitted to the terminal device 20 ( Step S122), the series of processing ends. Through the above-described processing, an unspecified number of terminal devices 20 access the first management server 10A via the network 40A, so that the terminal devices 20 display the construction status management information as shown in FIG. 9A, Operation management information shown in FIG. 9B can be displayed.

(Example of functional configuration of the first management server 10A according to the first embodiment)
FIG. 11 is a block diagram showing an example of functional configuration of the first management server 10A according to the first embodiment. As shown in FIG. 11, the first management server 10A includes a movement information storage unit 501, an acquisition unit 502, an identification unit 503, a registration unit 504, a notification content storage unit 505, a transport information storage unit 506, A communication unit 507 is provided.

The movement information storage unit 501 stores a predetermined area (first area to the fourth area), movement information indicating the movement status of the vehicle 300 is stored. Pavement materials are materials that require time and temperature control, such as ready-mixed concrete and asphalt mixtures. The predetermined area is an area surrounded by virtual boundaries (geofence). The movement status is the status of the vehicle 300 in areas such as "shipping", "passing through checkpoints", and "arrival". Also, the movement information storage unit 501 stores position information of a predetermined area. Note that the movement information storage unit 501 is realized by, for example, the movement information management table (RAM 53) shown in FIG. 5A.

Acquisition unit 502 acquires position information based on the measurement result of position measuring device 30 that measures the position of vehicle 300 . The position information is, for example, position information (for example, latitude and longitude information) indicating the current position of the vehicle 300 measured by the position measuring device 30 . The acquisition unit 502 acquires position information by receiving the position information from the position measuring device 30 via the second management server 10B. However, the information on the position may be information on an area (passage area) in which the vehicle is positioned (passed through). Specifically, when the vehicle 300 (the position measuring device 30) has a function of specifying a passing area, the acquiring unit 502 acquires the information indicating the passing area specified by the position measuring device 30 from the second It may be acquired by receiving from the position measuring device 30 via the management server 10B.

The position information also includes information on the time at the current location of vehicle 300 (or information on the time when vehicle 300 passed through the passage area). The time referred to here may be, for example, the time when the current position is measured by the position measuring device 30, or the first management server 10A receives the position of the vehicle 300 from the position measuring device 30 via the second management server 10B. It may be the time when the information about is received.

The specifying unit 503 specifies the movement information corresponding to the passage area through which the vehicle 300 passes from among the movement information stored in the movement information storage unit 501 based on the information regarding the position acquired by the acquisition unit 502 . Specifically, the specifying unit 503 uses the position information indicating the current position of the vehicle 300 acquired by the acquiring unit 502 and the position information of the area stored in the movement information storage unit 501 to determine whether the vehicle 300 has passed through. Identify the transit area to Furthermore, the identification unit 503 refers to the movement information storage unit 501 to identify movement information corresponding to the passage area. For example, when the transit area is the first area, the identifying unit 503 identifies movement information indicating "shipment" as the corresponding transport information.

The registration unit 504 registers (stores) transport information of the pavement material including the passage time in the passing area obtained from the position information and the movement information specified by the specifying unit 503 in the transport information storage unit 506 . The transport information includes vehicle operation management information (see FIG. 5B) and construction status management information (see FIG. 4). The transportation information storage unit 506 is realized by, for example, the construction status management table shown in FIG. 4 and the operation information management table (RAM 53) shown in FIG. 5B.

The notification content storage unit 505 stores notification content corresponding to a predetermined area. The content of the notification is, for example, a message suggesting the position of the vehicle 300 and the arrival time of the vehicle 300 to the construction site 302 . The message stored in the notification content storage unit 505 may be updated. For example, when a traffic jam occurs, the arrival time to the construction site 302 may differ from the preset time. In such a case, the travel history of the vehicle 300 may be used to update the content of the message (arrival time) using the time required to reach the construction site 302 .

The specifying unit 503 specifies the notification content corresponding to the passage area from the notification content stored in the notification content storage unit 505 based on the information about the position acquired by the acquisition unit 502 . Specifically, the identification unit 503 identifies the passage area through which the vehicle 300 passes, using the information indicating the current position of the vehicle 300 and the area position information stored in the movement information storage unit 501 . Further, the specifying unit 503 refers to the notification content storage unit 505 to specify the notification content corresponding to the passage area. For example, when the transit area is the first area, the identifying unit 503 identifies a message indicating "departure" as the corresponding notification content.

The communication unit 507 transmits to the terminal device 20 carrier information including the notification content specified by the specifying unit 503 . The communication unit 507 may transmit only the notification content identified by the identification unit 503, or may transmit operation information including, for example, the passage time of the passage area along with the notification content.

The communication unit 507 may also transmit, to the terminal device 20, the content of the pavement material transported by the vehicle 300 (construction status management information), for example, together with the content of the notification. The content of transport is, for example, information indicating the transport amount and quality of the pavement material transported by the vehicle 300 (the time from the start of kneading and the temperature of the pavement material). In this case, the acquisition unit 502 may refer to the construction status management table (see FIG. 4) to acquire the transport contents of the pavement material transported by the vehicle 300 . As a result, the person in charge of the site can grasp when the vehicle 300 will arrive and the quantity and quality of ready-mixed concrete transported by the arriving vehicle 300 .

Also, the communication unit 507 transmits transport information to the terminal device 20 in response to a transmission request from the terminal device 20 . However, the communication unit 507 may transmit the content of the notification among the transport information to the pre-registered terminal device 20 . Further, the communication unit 507 may transmit the operation management information and the construction status management information among the transportation information to the terminal device 20 in response to a transmission request from the terminal device 20 .

Further, the communication unit 507 may transmit the transport information to the terminal device 20 only when the vehicle 300 passes through a preset area. For example, the communication unit 507 transmits the transport information to the terminal device 20 when passing through an area (for example, a third area or a fourth area) close to the construction site 302, and an area far from the construction site 302 (for example, a 1 area or the second area), the transport information may not be transmitted to the terminal device 20 . As a result, important information (messages about nearby vehicles) can be preferentially notified to field personnel and the like.

In addition, for example, when a large number of vehicles 300 stop near the site and smooth unloading is not possible in the vicinity of the site, the first management server 10A may , or may notify that the arrival time will be delayed. In this case, the notification content storage unit 505 may store notification content indicating that there are many vehicles at the construction site 302 . Further, the identification unit 503 may identify the content of the notification indicating that there are many vehicles 300 when a certain number or more of the vehicles 300 are parked in the fourth area of the construction site 302 .

Similarly, for example, when the number of vehicles 300 arriving near the site is small, the first management server 10A notifies the vehicles 300 and the factory 301 along the route to that effect, or instructs them to advance the arrival time. You may notify us. In this case, the notification content storage unit 505 may store notification content indicating that the number of vehicles 300 at the construction site 302 is small. Further, when the number of vehicles 300 in the fourth area of the construction site 302 is less than a certain number, the specifying unit 503 may specify notification content indicating that the number of vehicles 300 is small.

Moreover, in road construction using paving materials, the transportation distance of the paving materials may increase as the construction progresses. Therefore, the time required for the vehicle 300 to unload (the time from passing through the fourth area to reaching the actual site) may change depending on the progress of the construction work. Therefore, according to the progress of the construction at the construction site 302, the content of the message corresponding to the fourth area ("arriving soon") is updated to, for example, "arrived at the entrance of the site". good too.

In addition, when the quality of the pavement material has deteriorated (for example, when 90 minutes have passed since the start of kneading due to traffic congestion, etc.), the first management server 10A may notify the content of the notification to that effect. . In this case, the notification content storage unit 505 may store notification content indicating deterioration of quality. Further, the identification unit 503 may identify the notification content indicating the deterioration of quality together with the notification content corresponding to the transit area. In addition, in an area far from the construction site 302, if the quality drops below a certain level (for example, when 60 minutes have passed since the start of kneading), the quality will further decrease when arriving at the construction site 302. progress) can be expected. For this reason, the identifying unit 503 may identify the content of notification indicating deterioration of quality according to the passing area (when the vehicle 300 is in an area far from the construction site 302).

The acquisition unit 502, the identification unit 503, and the registration unit 504 described above are implemented by the CPU 51 shown in FIG. 2 executing the management program. Moreover, the communication part 507 is implement|achieved by communication I/F56.

As described above, when the vehicle 300 passes through a predetermined area, the first management server 10A according to the first embodiment provides transport information including the movement information corresponding to the passing area and the passage time in the passing area. I decided to register the information. As a result, it is possible to appropriately manage the transportation status of the pavement material. Therefore, the on-site person in charge, the factory staff, etc. who have the terminal device 20 can share the transportation status with respect to the progress of the construction, and can accurately grasp the transportation status. Therefore, deterioration of the quality of the pavement material used at the construction site 302 can be suppressed.

Further, the first management server 10A transmits a message corresponding to the passing area to the terminal device 20 when the vehicle 300 passes through the predetermined area. As a result, a message (conveyance status) can be notified to the person in charge on site or the like. Therefore, the person in charge on site can grasp the transportation status in real time.

Further, the first management server 10A may transmit to the terminal device 20 transport information including transport details of the pavement material transported by the vehicle 300 . As a result, the person in charge at the site can grasp the transport amount and quality of the transport material transported by the arriving vehicle 300 .

In addition, according to the management system 1 according to the first embodiment, since the configuration is such that the transport information is managed only using the positional information transmitted from the vehicle 300, it is possible to eliminate the need for new equipment investment. can. That is, communication charges (communication charges between the terminal device 20 and the first management server 10A, communication charges between the position measuring device 30 and the second management server 10B, and communication charges between the first management server 10A and the second management server 10B ) and the usage fees of the first management server 10A and the second management server 10B, the management system 1 can be realized with a low-cost configuration.

(Embodiment 2)
Next, Embodiment 2 according to the present invention will be described. In the second embodiment, in addition to the above-described first embodiment, the passage order of the areas through which the vehicle 300 passes is set in advance, and when the areas are passed according to the passage order, the registration of the transportation status and the A configuration for notifying messages will be described. In other words, in the second embodiment, even when the vehicle 300 passes through an area, if the vehicle 300 does not pass through the area according to the order of passage, operation information registration and message notification are not performed. . In addition, in the following description, the points described in Embodiment 1 are denoted by the same reference numerals, and the description thereof is omitted.

(Outline of Embodiment 2)
FIG. 12 is an explanatory diagram showing an overview of the second embodiment. In FIG. 12, a construction site 302 (seventh area) indicates, for example, a place where road construction is performed on an expressway. A plurality of areas (first area to seventh area) are provided on the route 600 from the factory 301 to the construction site 302 . The first management server 10A stores the passing order of each area. For example, the passing order is 1st area->2nd area->3rd area->4th area->5th area->6th area->7th area. In road construction on an expressway, for example, the vehicle 300 may pass through the same area multiple times because it may reach the construction site 302 via the opposite lane.

Specifically, as shown in FIG. 12, the vehicle 300 moves through the third area and the fifth area several times while reaching from the first area (factory 301) to the seventh area (construction site 302). will pass. Specifically, after passing through the fourth area, it passes through the third area again, and after passing through the sixth area, it passes through the fifth area again. Such passage through the same area is passage that does not correspond to the order of passage. In the second embodiment, when passing through an area that does not correspond to the passing order, neither registration of operation information in the operation information management table of FIG. 5B nor transmission of messages to the terminal device 20 is performed.

(Example of message management table according to the second embodiment)
FIG. 13 is an explanatory diagram of an example of a message management table according to the second embodiment; The message management table shown in FIG. 13 also stores some information stored in the construction status management table of FIG. 4, the movement information management table of FIG. 5A, and the message management table of FIG. In this specification, the table shown in FIG. 13 is called "message management table", but may be called "operation information management table".

In FIG. 13, the message management table includes information of "transit order", "area ID", "movement information", "message", "transit time", and "shipment quantity". In addition, in FIG. 13, "area ID", "movement information", "message", and "passing time" are the same as those described in the first embodiment. "Passing order" indicates the order of passing areas. Also, "8" in the "passing order" indicates the end of registration of the operation information for the vehicle 300. FIG. The “shipment quantity” indicates the amount of pavement material conveyed by the vehicle 300 .

As for "area ID", "movement information", and "message", information is stored corresponding to seven areas. The "passage time" is information on the time that is stored when the vehicle 300 passes through the area in the order of passage. In FIG. 13, the "passing time" corresponding to the area IDs "005" to "007" is blank, indicating that the vehicle 300 is traveling in front of the area ID "005". ing.

(Example of processing for managing operation information of vehicle 300 performed by first management server 10A according to the second embodiment)
FIG. 14 is a flowchart showing an example of a process of managing operation information of the vehicle 300 performed by the first management server 10A according to the second embodiment. In FIG. 14, the first management server 10A determines whether or not the vehicle 300 has passed through the first area (factory 301) corresponding to the area ID "001" (step S201). The first management server 10A waits until the vehicle 300 passes through the first area (step S201: NO). When the vehicle 300 passes through the first area (step S201: YES), the first management server 10A identifies the vehicle 300 (step S202). Further, in step S202, the first management server 10A sets the passing order I corresponding to the identified vehicle 300 to "1".

Next, the first management server 10A refers to the message management table of FIG. 13 and identifies movement information (information indicating "shipment") corresponding to the area ID "001" indicating the first area (step S203). . Then, the first management server 10A acquires the passage time of passing through the first area using the measurement time information transmitted from the position measuring device 30 together with the position information (step S204). Next, the first management server 10A stores the passage time (operation information) of passing through the first area in the message management table of FIG. 13 (step S205).

Then, the first management server 10A refers to the message management table of FIG. 13 and identifies the message ("departed") corresponding to the area ID "001" (step S206). The first management server 10A then transmits the identified message to the registered terminal device 20 (step S207). Then, the first management server 10A sets the passage order I to "2" (step S208).

Next, the first management server 10A determines whether or not the vehicle 300 has passed through any area (step S209). The first management server 10A waits until the vehicle 300 passes through any area (step S209: NO). When vehicle 300 passes through any area (step S209: YES), first management server 10A identifies the area (step S210).

Then, the first management server 10A determines whether or not the area ID of the specified area matches the area ID corresponding to the passage order I (step S211). When the first management server 10A determines that the area ID of the specified area and the area ID corresponding to the passage order I do not match (step S211: NO), that is, if the area is an area according to the passage order If not, the process returns to step S209 without storing operation information or transmitting a message.

On the other hand, when the first management server 10A determines that the area ID of the identified area and the area ID corresponding to the passage order I match (step S211: YES), the first management server 10A refers to the message management table of FIG. The movement information corresponding to the area ID of the selected area is specified (step S212). Then, the first management server 10A acquires the passage time of passing through the area using the measurement time information transmitted from the position measuring device 30 together with the position information (step S213). Next, the first management server 10A stores the passage time corresponding to the area in the message management table of FIG. 13 (step S214).

Then, the first management server 10A refers to the message management table of FIG. 13 and identifies the message corresponding to the area ID of the identified area (step S215). Next, the first management server 10A transmits the identified message to the registered terminal device 20 (step S216). In steps S207 and S216, the first management server 10A may transmit not only the message but also movement information, passage time information, and shipping quantity information to the terminal device 20. FIG. Then, the first management server 10A adds "1" to the passage order I (step S217).

Next, the first management server 10A determines whether or not the passage order I is "8" (step S218). When the first management server 10A determines that the passage order I is not "8" (step S218: NO), the process returns to step S209. When the first management server 10A determines that the passage order I is "8" (step S218: YES), it ends the management of the vehicle 300 (registration of operation information, etc.) (step S219). End the process.

By the above-described processing, the first management server 10A can register operation information and transmit a message to the terminal device 20 when the vehicle 300 passes through the areas in the order of passage. Therefore, the terminal device 20 can display the contents stored in the message management table shown in FIG. 13, for example.

(Example of functional configuration of the first management server 10A according to the second embodiment)
FIG. 15 is a block diagram showing an example of functional configuration of the first management server 10A according to the second embodiment. The first management server 10A shown in FIG. 15 differs from the functional configuration of the first management server 10A shown in FIG.

Passing order storage unit 510 stores the passing order when vehicle 300 passes through a plurality of areas. The passage order is appropriately set and stored for each construction site 302 according to the time zone and date, for example, by the staff of the site office or the person in charge of the construction site 302 . The passage order storage unit 510 is realized by, for example, the message management table (RAM 53) shown in FIG.

The registration unit 504 refers to the passing order storage unit 510 and registers the transport information when the passing area is an area according to the passing order. In other words, the registration unit 504 does not register the transport information when the passage area is not an area according to the passage order. That is, for example, when the vehicle 300 passes through an area that it once passed through again (when it does not follow the order of passage), the transport information is not registered.

In the above description, operation information is registered while the vehicle 300 travels from the factory 301 to the construction site 302. However, when the vehicle 300 returns from the construction site 302 to the factory 301 (return trip) Operation information of the vehicle 300 can be registered. In this case, the movement information indicating the movement status for the return trip (for example, "unloading completed" or "arrived at the factory") is stored for each area, and when the vehicle 300 passes through the area, the movement corresponding to the area is stored. Information should be registered. Also, a message for returning home according to the area (such as "We will arrive at the factory in 10 minutes") is stored, and when the vehicle 300 passes through the area, the message for returning home corresponding to the area is transmitted. You may make it Also, in this case, if the same area is to be passed through twice, the passage order for the return route may be set in the passage order storage unit 510 .

As described above, according to the first management server 10A according to the second embodiment, the same effects as those of the first embodiment can be obtained. In particular, in the second embodiment, the transport information is registered when the passing area is an area according to the passing order. That is, when the passing area is not an area according to the passing order, the transport information is not registered. Therefore, even when the same area is passed multiple times from the factory 301 to the construction site 302, the transport condition of the pavement material can be appropriately managed.

A program for realizing the first management server 10A described above may be recorded in a computer-readable recording medium, and the program may be read and executed by a computer system. It should be noted that the "computer system" referred to here includes hardware such as an OS and peripheral devices. The term "computer-readable recording medium" refers to portable media such as flexible discs, magneto-optical discs, ROMs and CD-ROMs, and storage devices such as hard discs incorporated in computer systems. In addition, "computer-readable recording medium" means a volatile memory (RAM) inside a computer system that acts as a server or client when a program is transmitted via a network such as the Internet or a communication line such as a telephone line. , includes those that hold the program for a certain period of time. Further, the above program may be transmitted from a computer system storing this program in a storage device or the like to another computer system via a transmission medium or by a transmission wave in a transmission medium. Here, the "transmission medium" for transmitting the program refers to a medium having a function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line. Further, the program may be for realizing part of the functions described above. Further, it may be a so-called difference file (difference program) that can realize the above-described functions in combination with a program already recorded in the computer system.
