  The conventional technology represented by Patent Document 1 uses a GPS (Global Positioning System) and a mobile communication network. For this reason, when a mobile body exists indoors, the positional information of a mobile body cannot be acquired, and when a mobile base station does not exist in the periphery, it becomes impossible to transmit positional information. As described above, when a specific communication network cannot be used, there is a problem in that the position of the person carrying the mobile object cannot be grasped.

Embodiment 1 FIG.
FIG. 1 is a block diagram showing a configuration of a moving object monitoring apparatus according to the present invention. Hereinafter, although the mobile monitoring device intended to be mounted on or carried by the mobile will be described, the device may be applied to infrastructure equipment. In FIG. 1, the mobile communication device according to the present invention is mounted or carried on a mobile body, and includes a position information acquisition unit 110, an identification information storage unit 120, a movement state information acquisition unit 130, an acquisition information control unit 140, and a history information storage. Unit 150 and wireless communication unit 160.

The moving body refers to a vehicle that moves when operated by a human, such as a vehicle or a bicycle, or an animal such as a human, a dog, or a cat. The mobile monitoring device may be incorporated in or installed in a portable device such as a mobile phone carried by a person or an existing device such as a car navigation device installed in a vehicle or a cycle computer installed in a bicycle, and used as a separate unit. It may be.
The device is a product in which a GPS (Global Positioning System) receiver IC has already been incorporated, and can be incorporated relatively inexpensively and easily. Moreover, it can be expected that an existing communication network can be used. Hereinafter, the moving body monitoring device mounted on or carried by the moving body is simply referred to as “a moving body monitoring device included in the moving body”.

  The position information acquisition unit 110 is a component that acquires position information of the moving object. For example, it may be preferable to use a GPS capable of recognizing three-dimensional position information by receiving a signal from an artificial satellite turning around the earth. By using GPS, it is possible to acquire not only position information but also time information output by a satellite. Further, the traveling direction and speed can be calculated from the change in position over time. The azimuth information and the speed information may be acquired by default from the position information acquisition unit 110, or may be calculated by the acquisition information control unit 140.

In recent years, DSSS (Safety Driving Support System) that obtains position information, signal information, and the like through communication with infrastructure devices such as optical beacons and DSRC (Dedicated Short Range Communication) and supports safe driving is becoming widespread. Here, an optical beacon is an application of near-infrared technology with a very high directivity to perform bidirectional communication with a vehicle-mounted device of a traveling vehicle and vehicle sensing to provide highly accurate traffic information. . DSRC is a one-way or two-way wireless communication technology using the 5.8 GHz band ISM (Industry Science Medical band) designed specifically for vehicle communication, and is constant within the communication area. It is possible to provide traffic information that is sequentially updated in a cycle.
ETC (Electric Toll Collection; registered trademark), a system for automating toll payment developed to prevent congestion on toll roads, has become widespread. Therefore, when a device corresponding to this system is mounted, it is also possible to acquire position information by using road-to-vehicle narrow area communication.

  The identification information storage unit 120 is a storage unit that stores identification information unique to the mobile object monitoring apparatus. For example, it refers to a solid identification number of a mobile phone or a manufacturing number of a car navigation device. 1 is a roadside monitoring apparatus, identification information unique to the roadside monitoring apparatus is stored in the identification information storage unit 120. Based on this identification information, information regarding each mobile monitoring device can be specified from the database of the data management device 10. Further, not only the identification information of the own device but also the identification information of the monitoring object mobile monitoring device acquired from the wireless communication unit 160 is stored together. An example of the identification information is as shown in FIG. Here, the identification information (ID) of its own mobile monitoring device is “1”, and the identification information (ID) of the monitoring target mobile monitoring device is “2”, “3”, and “5”.

  The movement state information acquisition unit 130 is a component that acquires element information representing the state of the moving object. For example, when the movement state information acquisition unit 130 is realized by a pulse obtained from a pulse meter of a wellness mobile phone, a cadence (pedal rotation speed) sensor attached to a cycle computer, a speed sensor, a heart rate monitor, or the like, The obtained speed information and heart rate are acquired as element information representing the state of the moving body. Further, when the moving body is a vehicle, the moving state information acquisition unit 130 is realized by a wire harness or CAN (Controller Area Network), and vehicle speed pulse signals, turn signal information, back lamp information, and the like obtained therefrom are moved. Acquired as element information representing the state of the body. Furthermore, when the moving body is a vehicle or a bicycle, the movement state information acquisition unit 130 detects the locked state as element information representing the state of the moving body. Note that the mobile object monitoring device can acquire and use element information representing the state of the mobile object only when a sensor or the like that is the movement state information acquisition unit 130 is mounted or connected. When the movement state information acquisition unit 130 is not mounted or connected and element information cannot be acquired, only various information obtained from the position information acquisition unit 110 is used.

The acquisition information control unit 140 creates the state information of the mobile body on which the self-device is mounted or carried from the position information, the identification information, and the element information indicating the state of the mobile body, and the movement of the self-device and other mobile bodies It is a component that creates history information by classifying state information acquired from a body monitoring device or a roadside monitoring device for each identification information.
Specifically, the acquisition information control unit 140 is an element that represents various information obtained from the position information acquisition unit 110, identification information obtained from the identification information storage unit 120, and the state of the moving body obtained from the movement state information acquisition unit 130. Encode information to create status information. If the various information obtained from the position information acquisition unit 110 is, for example, GPS information, the information is decoded to extract time information, position information, speed information, and direction information.
In addition, when vehicle speed pulse and cadence information can be acquired as element information representing the state of the moving body, it is assumed that the calculation result can be used preferentially so that more accurate speed calculation is possible. An example of element information representing the state of the encoded mobile object is as shown in FIG. In the example of FIG. 3, the identification information (ID) is “1”, that is, the position information (latitude and longitude), the moving speed, and the direction of the own device are acquired as element information indicating the state of the moving body. Table information is created as status information.

  In addition, the acquisition information control unit 140 transmits the state information of the mobile body having itself via the wireless communication unit 160 to the mobile body monitoring device and the roadside monitoring device of other mobile bodies existing in the communication area. Status information is acquired from the moving body monitoring device and the roadside monitoring device of the moving body. When the identification information included in the state information is equal to the identification information related to the monitoring target stored in the identification information storage unit 120, the state information is transferred to the roadside monitoring device or the like via the wireless communication unit 160.

  Further, the acquisition information control unit 140 obtains the time obtained by the position information acquisition unit 110 with respect to the state information of the mobile body having the own device and the state information acquired from the mobile body monitoring device of another mobile body. History information is created for each piece of identification information by associating information. It is assumed that the history information is stored in the history information storage unit 150 after being converted into a format that can be easily compressed taking into consideration that the storage capacity is limited. An example of the history information is as shown in FIG. That is, the history information is information in which the state information shown in FIG. Further, each data of the history information is represented by a difference from the base data as shown in FIG. As a result, the data capacity can be reduced.

The history information storage unit 150 is a storage unit that stores history information created in the acquisition information control unit 140. Note that the identification information to be monitored is preferentially stored in consideration of the storage capacity, and is discarded when a certain time has elapsed.
Further, when a reference request for history information related to specific identification information is acquired from the acquisition information control unit 140, the history information is provided to the acquisition information control unit 140.

  The wireless communication unit 160 is a component that bidirectionally communicates state information or history information with a moving body monitoring device or roadside equipment of another moving body. For example, it is appropriate to use a wireless ad hoc network as a communication method. In ad hoc communication, each mobile monitoring device autonomously performs routing so that communication can be performed without a fixed network. In addition, when the device plays a role of a router, information can be transferred by multi-hop communication. As an example of ad hoc communication, it is assumed that WAVE (Wireless Access in Vehicular Environments) based on IEEE802.11p developed for inter-vehicle communication based on the wireless LAN standard is used. By using this standard, adaptation to communication between mobile bodies moving at high speed can be expected. In addition, since the protocol is similar to other wireless LAN standards, it is also possible to switch to an existing wireless LAN standard such as WiFi and use it together.

  Instead of ad hoc wireless communication, wireless communication using the T-75 communication standard used for the above-mentioned ETC or DSRC communication, near infrared communication used for optical beacons, etc. may be used. It is also assumed that the function of the mobile monitoring device is incorporated in a fixed station rather than a mobile. Moreover, it may have a plurality of communication means, and when it is incorporated into a mobile phone, it is possible to use both a mobile communication network and a wireless ad hoc network.

  FIG. 5 is a diagram showing a configuration of the moving object monitoring system according to the first embodiment. The mobile body monitoring system according to Embodiment 1 includes mobile bodies 1 to 3, mobile body monitoring devices 100, 200, and 300 that mobile bodies 1, 2, and 3 have, roadside monitoring devices 4 and 5, and And a data management apparatus 10 connected via a network. Here, the moving bodies 1 and 2 shall show a vehicle. Hereinafter, the moving bodies 1 and 2 are described as vehicles 1 and 2 as appropriate.

  The mobile body monitoring devices 100 and 200 mounted on the vehicles 1 and 2 are mobile body monitoring devices having the configuration shown in FIG. 1, and the mobile body included in the mobile body entering the communication area around the vehicles 1 and 2. It communicates with the monitoring device and the roadside monitoring device. In the first embodiment, for example, it is assumed that a mobile monitoring device is built in or connected to a mobile terminal such as a communication car navigation device or a smart phone, and a communication network or mobile phone that is uniquely constructed by a car manufacturer exclusively for a telematics service to a vehicle. It is assumed that a telephone communication network can be used.

  The roadside monitoring devices 4 and 5 have the same configuration as the moving object monitoring device shown in FIG. 1, and both the moving object monitoring devices 100 to 300 that run near and directly below the position where the own device is installed. It is a device that performs directional communication, and acquires identification information and status information of the moving body monitoring devices 100 to 300 that the moving bodies 1 to 3 have. The roadside monitoring devices 4 and 5 read the information acquired from the mobile monitoring devices 100 to 300 from the storage units 120 and 150 and transmit the information to the data management device 10. As the roadside monitoring devices 4 and 5, for example, an existing optical beacon roadside machine, a DSRC roadside machine, an ETC gate, or the like is assumed.

  The data management device 10 is a data management device that is connected to a network (communication line) such as the Internet including a communication network independently managed by a car manufacturer and a mobile communication network such as a mobile phone, and includes identification information of the mobile monitoring device. A database in which status information is registered correspondingly is managed. For example, when the monitoring target is the moving body monitoring device 100 of the vehicle 1 (the moving body 1), the data management device 10 receives the identification information and the state information of the moving body monitoring device 100 received from the devices 200 and 300. Based on the above, the travel route of the vehicle 1 is monitored. When abnormality is recognized in the movement route of the vehicle 1, the data management apparatus 10 notifies the mobile monitoring apparatus 300 to that effect.

It should be noted that the network connecting the mobile monitoring devices constituting the mobile monitoring system according to the present invention and between the mobile monitoring devices and the data management device 10 is a bidirectional communication line that can be transmitted and received between the devices. Good. That is, the mobile monitoring system according to the present invention can be configured using any communication network having such a function. In particular, the network is not limited to an existing specific communication network, and a plurality of communication networks can be linked.
Moreover, although the data management apparatus 10 has the database, the roadside monitoring apparatuses 4 and 5 may have the database.

  The moving body 3 is assumed to be a monitor who monitors the owner of the vehicle 1 and the driver of the vehicle 1. Hereinafter, the moving body 3 is appropriately referred to as a supervisor 3. Similar to the mobile monitoring devices 100 and 200, the mobile monitoring device 300 is also a mobile monitoring device having the configuration shown in FIG. 1, for example, a connectable browser such as a computer terminal such as a personal computer or a mobile phone. It is installed or connected to the installed communication terminal. In addition, the moving body monitoring device 300 can monitor the moving state of the vehicle 1 by connecting to the data management device 10 using an existing communication network. When the data management device 10 finds an abnormality in the moving route of the vehicle 1, the moving body monitoring device 300 of the supervisor 3 notifies the abnormality that has occurred in the moving route of the vehicle 1 by an alarm using sound and images. It is possible.

Next, the operation will be described.
FIG. 6 is a flowchart showing processing operations performed by the moving object monitoring system according to the first embodiment. Details of the processing will be described with reference to FIG. FIG. 6 shows the case where the monitoring process of the mobile body monitoring device is performed using the roadside monitoring device 4 constituting the mobile body monitoring system according to the first embodiment, that is, on the travel route of the vehicle 1. The monitoring process using the roadside monitoring device 4 will be described as an example.

First, the data management device 10 searches the registered content of the database with the identification information (ID) “1” related to the moving body monitoring device 100 to confirm whether or not the vehicle 1 is a monitoring target (step ST601). Here, when the vehicle 1 is not a monitoring target (step ST601; NO), the moving body monitoring process shown in FIG. 6 is terminated.
When the identification information (ID) “1” related to the moving body monitoring device 100 is registered in the database and the vehicle 1 is the monitoring target (step ST601; YES), the data management device 10 is registered in the database. Based on the state information or history information of the moving body monitoring device 100, it is confirmed whether or not a predetermined passage time (expected passage time) for the vehicle 1 to reach the installation point of the roadside monitoring device 4 has elapsed (step ST602). ). Note that the acquisition information control unit 140 of the roadside monitoring device 4 may make this determination.

  If the predetermined traffic time has not elapsed (step ST602; NO), the data management device 10 indicates that the state information acquired from the mobile monitoring device 100 to the roadside monitoring device 4 at the predetermined traffic time is the roadside monitoring device 4. Wait until it is sent. That is, when the vehicle 1 reaches the installation point of the roadside monitoring device 4 in a predetermined traffic time, bidirectional communication is performed between the mobile monitoring device 100 and the roadside monitoring device 4. By this two-way communication, the roadside monitoring device 4 receives from the moving body monitoring device 100 identification information (ID) “1”, position information P1, time information T1, and the state of the moving body related to the moving body monitoring device 100. Information S1 is acquired (step ST603). Thereafter, the data management apparatus 10 acquires each piece of information acquired from the mobile monitoring apparatus 100 from the roadside monitoring apparatus 4 (step ST604).

  The data management device 10 collates the information acquired from the roadside monitoring device 4 with the database, and determines from the position information P1 of the moving object monitoring device 100 whether or not there is no problem with the previous moving route of the vehicle 1 (step). ST605). If there is no problem with the determination result (step ST605; YES), the roadside monitoring device 4 ends the monitoring process of the moving object monitoring device 100 assuming that the movement of the vehicle 1 has ended without any problem. That is, the moving body monitoring device 100 included in the vehicle 1 is removed from the monitoring target (step ST606). In addition, when it can not confirm in step ST603,605 that there is no problem in the moving route of the vehicle 1 (step ST603,605; NO), the process from step ST602 is repeatedly performed.

  When the data management device 10 determines that the time when the mobile monitoring device 100 reaches the roadside monitoring device 4 and transmits the status information or history information of the mobile monitoring device 100 has passed a predetermined traffic time ( In step ST602; YES), the process proceeds to step ST607. In step ST607, the data management device 10 indicates that the moving route of the vehicle 1 is abnormal with respect to the moving body monitoring devices 200 and 300 and the roadside monitoring devices 4 and 5, and the identification information (ID of the moving body monitoring device 100) ) Notify with “1”. Thereby, the supervisor 3 can recognize that an abnormality has occurred in the travel route of the vehicle 1 via the browser of the mobile object monitoring apparatus 300.

  Next, the acquisition information control unit 140 of the moving body monitoring device 200 included in the vehicle 2 has history information related to the identification information (ID) “1” of the moving body monitoring device 100 in the history information storage unit 250. Is confirmed (step ST608). If the history information storage unit 250 has history information related to the identification information (ID) “1” (step ST608; YES), the acquisition information control unit 140 of the mobile monitoring device 200 uses the wireless communication unit 160. History information regarding the mobile monitoring device 100 is notified to the data management device 10 by radio communication using telematics or a mobile communication network (step ST609). Here, the history information may be notified to the data management device 10 via the roadside monitoring devices 4 and 5 by communicating with the roadside monitoring devices 4 and 5.

  Next, the data management apparatus 10 can notify the monitoring person 3 of the history contents related to the mobile monitoring apparatus 100 by performing wireless communication with the mobile monitoring apparatus 300 (step ST610). Since the history content is composed of the base point data and the difference data as shown in FIG. 4, the vehicle 1 is superimposed on the map using a format that is easy to decode and visually confirm, for example, map matching. It is desirable to display the travel route.

  In addition, when the history information storage unit 250 does not have the history information related to the identification information (ID) “1” (step ST608; NO), the acquisition information control unit 140 of the mobile monitoring device 200 displays the identification information of the monitoring target. The identification information (ID) “1” is stored in the identification information storage unit 120 (step ST611). As a result, the information related to the identification information (ID) “1” is acquired in the future.

By monitoring each other between the mobile body monitoring devices as described above, the supervisor 3 can obtain the past travel route of the vehicle 1 from the history information of the mobile body monitoring device 100 mounted on the monitored vehicle 1. The travel time, the travel direction, and the travel speed can be grasped. For example, the acquisition information control unit 140 of the moving body monitoring apparatus 300 managed by the monitor 3 not only notifies the monitor 3 that an abnormality has occurred in the travel route of the vehicle 1 but also the past movement of the vehicle 1. The current movement state of the vehicle 1 (such as the route on which the vehicle 1 is currently traveling) is estimated from the route, travel time, travel direction, and travel speed. Thereby, the vehicle 1 can be searched easily.
In the first embodiment, the roadside monitoring device 4 performs the mobile body monitoring processing operation performed with the mobile body monitoring device 100. However, the roadside monitoring device 5 is similarly implemented.

  As described above, according to the first embodiment, the position information acquisition unit 110 that is mounted on the roadside device and acquires the position information of the own device, and the identification information storage that stores the identification information unique to the mobile object monitoring device. Unit 120, wireless communication unit 160 that communicates with an external device, and transmission / reception of state information between the mobile monitoring device by wireless communication unit 160 and acquisition of history information that summarizes the state information in time series An information control unit 140 and a history information storage unit 150 that stores history information of the moving body monitoring device in association with identification information unique to the moving body monitoring device. When a mobile object carrying or carrying a device moves on a predetermined movement route via the installation point of its own device, if the mobile object reaches the installation point of its own device within a predetermined expected transit time, wireless Communication unit 160 If status information is transmitted / received to / from the moving body monitoring apparatus and the moving body does not reach the installation location of the own apparatus, an abnormality has occurred in the movement of the moving body by the wireless communication unit 160. This is notified to other mobile monitoring devices. By doing in this way, the opportunity which acquires the movement condition of the moving body in a predetermined moving route can be increased significantly, and tracking of a moving body and estimation of a moving route can be performed.

  Further, according to the first embodiment, the acquisition information control unit 140 transmits / receives state information to / from the moving body monitoring device by the wireless communication unit 160, and the state information received from the moving body monitoring device is updated. If the included identification information is identification information unique to the moving body monitoring device of the moving object to be monitored, the history information is received from the moving object monitoring device, stored in the history information storage unit 150, and the movement of the monitoring object is detected. If the identification information is not unique to the moving body monitoring device of the body, identification information unique to the moving body monitoring device of the moving body to be monitored is notified to the moving body monitoring device. By doing in this way, the opportunity to acquire the history information of the moving body monitoring device can be greatly increased, tracking of the moving body based on the history information acquired from the moving body monitoring device of the moving body to be monitored and A route of travel can be estimated.

I do. In addition, the mobile monitoring device 200 transmits history information indicating a communication history with the mobile monitoring device 100 to the data management device 10.
For example, it is assumed to be mounted on a simple transmission device such as RFID (Radio Frequency IDentification) or a portable terminal such as a smartphone.

  The roadside monitoring devices 6 and 7 have the same configuration as that of the moving body monitoring device shown in FIG. 1, and perform two-way communication with the moving body monitoring devices 100 to 300 that run near and directly below the installed position. By doing so, identification information (ID), state information or history information of the mobile monitoring device is acquired. The roadside monitoring devices 6 and 7 read the information acquired from the mobile monitoring devices 100 to 300 from the storage units 120 and 150 and transmit the information to the data management device 10. For example, in order to monitor the school route of children, a roadside monitoring device installed in a utility pole or school is assumed.

  The data management device 10 is a data management device that is connected to a network (communication line) such as the Internet including a mobile communication network such as a mobile phone, and the status information corresponds to the identification information (ID) of the mobile monitoring device. The registered database shall be managed. For example, when the monitoring target is a person 1 (mobile body 1), the data management device 10 is based on the identification information of the mobile body monitoring device 100 held by the person 1 and the status information received from the devices 200 and 300. In addition, the movement route and position of the person 1 are monitored. When an abnormality is recognized in the movement route of the person 1, the fact is notified to the mobile monitoring device 300.

  It should be noted that the network connecting the mobile monitoring devices constituting the mobile monitoring system according to the present invention and between the mobile monitoring devices and the data management device 10 is a bidirectional communication line that can be transmitted and received between the devices. Good. That is, the mobile monitoring system according to the present invention can be configured using any communication network having such a function. In particular, the network is not limited to an existing specific communication network, and a plurality of communication networks can be linked. Moreover, although the data management apparatus 10 has the database, the roadside monitoring apparatuses 6 and 7 may have the database.

  The house 20 is used for simulating an environment in which the mobile body monitoring device 100 cannot acquire position information, for example, in order to assume a situation where the mobile body monitoring device 100 carried by the person 1 exists in a room where a GPS satellite cannot be captured. To do.

  The moving body 3 refers to a monitor such as a family or a lover who monitors the person 1 (moving body 1). Hereinafter, the moving body 3 is appropriately described as the monitor 3. Similar to the mobile monitoring devices 100 and 200, the mobile monitoring device 300 is a mobile monitoring device having the configuration shown in FIG. 1, and is equipped with a connectable browser such as a computer terminal such as a personal computer or a mobile phone. Realized by a communication terminal. By connecting the mobile monitoring device 300 to the data management device 10, it is possible to monitor the state of the mobile monitoring device 100 that the person 1 has. When the data management apparatus 10 finds an abnormality in the moving body monitoring apparatus 100, the moving body monitoring apparatus 300 possessed by the supervisor 3 alerts the abnormality of the moving body monitoring apparatus 100 possessed by the person 1 using sound and images. Can be notified.

Next, the operation will be described.
FIG. 8 is a flowchart illustrating processing operations performed by the mobile monitoring system according to the second embodiment. When the monitoring person 3 searches for the person 1 using the mobile monitoring system according to the second embodiment. Is described. For example, in an environment where the person 1 can connect to the mobile communication network, the mobile monitoring apparatus 100 that the person 1 has communicates with the data management apparatus 10 directly, or the mobile monitoring apparatus 300 that the monitor 3 has. It becomes possible to confirm the state and position of the mobile monitoring device 100 by communicating with. However, in an environment in which the person 1 cannot acquire position information or in an environment in which it is difficult to connect to the mobile communication network due to radio wave conditions or the like, the monitor 3 cannot check the status and position of the mobile monitoring device 100. Is possible. In addition, although the example of FIG. 7 has shown the example in which the person 1 exists in the house 20, it is not limited to the said condition, For example, the condition etc. which are mountain climbing and winter sports are assumed.

First, the monitoring person 3 uses the moving body monitoring apparatus 300 to transmit the identification information (ID) “1” of the moving body monitoring apparatus 100 of the person 1 via the mobile communication network so that the person 1 can be monitored. To the data management apparatus 10 (step ST801).
Next, in step ST802, the data management device 10 indicates that the person 1 is the monitoring target together with the identification information (ID) “1” of the mobile monitoring device 100, and the mobile monitoring devices 100 and 200 and the roadside monitoring device. 6 and 7 (step ST802). Here, since the person 1 exists inside the house 20 as described above, it is assumed that the moving object monitoring apparatus 100 cannot acquire the notification.

The acquisition information control unit 140 of the mobile monitoring device 200 and the roadside monitoring devices 6 and 7 receives the identification information (ID) “1” of the monitoring target mobile monitoring device 100 received from the data management device 10 as the identification information storage unit 120. (Step ST803). At this time, the acquisition information control unit 140 relates to the monitoring target in which the identification information of the moving body monitoring device included in the monitoring target moving body newly received by the wireless communication unit 160 is already stored in the identification information storage unit 120. If it does not match the identification information, the identification information storage unit 120 is updated with the newly received identification information as the identification information related to the monitoring target.
Here, in the history information storage unit 150 of the mobile monitoring device 200, when there is history information indicating a communication history with the mobile monitoring device 100 associated with the identification information (ID) “1”, the above-described first embodiment. Although it is possible to transmit the information to the data management apparatus 10 as shown, detailed explanation is omitted because it has already been explained.

  Next, the acquisition information control unit 140 of the mobile monitoring devices 100 and 200 and the roadside monitoring devices 6 and 7 communicates status information between the mobile monitoring devices and between the mobile monitoring device and the roadside monitoring device. Then, it is confirmed whether or not the identification information (ID) of the mobile monitoring device of the communication partner is “1” (step ST804). When the identification information (ID) associated with the state information acquired by the wireless communication unit 160 of the mobile monitoring device 200 is “1” (step ST804; YES), the acquisition information control unit of the mobile monitoring device 200 140 uses radio communication section 160 to notify that person 1 is a monitoring target, and obtains history information (history information of mobile monitoring device 100) that summarizes this state information in time series (step ST805). ).

  Thereafter, the mobile monitoring device 100 transmits history information related to the identification information (ID) “1” to the data management device 10 either spontaneously or via the mobile monitoring device 200 (step ST806). Here, the mobile monitoring device 200 manages the history information related to the identification information (ID) “1” received from the mobile monitoring device 100 via the roadside monitoring device 6 or the roadside monitoring device 7 in multi-hop communication. You may transmit to the apparatus 10. When performing multi-hop communication, information related to the mobile monitoring devices 100 and 200 is transmitted. However, the information related to the monitoring target identification information (ID) “1” is preferentially transmitted. And Thereby, the moving body monitoring apparatus 300 of the monitoring person 3 can acquire the history information and the like of the moving body monitoring apparatus 100 via the data management apparatus 10. The acquisition information control unit 140 of the moving body monitoring apparatus 300 estimates the current position of the person 1 from the history information of the moving body monitoring apparatus 100 and notifies the monitoring person 3.

When the identification information (ID) is not “1” (step ST804; NO), the acquisition information control unit 140 of the mobile monitoring device 200 uses the wireless communication unit 160 to communicate with the mobile monitoring device of the communication partner. Is notified that the person 1 is the monitoring target together with the identification information (ID) “1” related to the mobile monitoring apparatus 100 (step ST807).
Receiving this notification, the acquisition information control unit 140 of the mobile monitoring device checks whether or not the history information related to the identification information (ID) “1” exists in the history information storage unit 150 (step ST808). Here, when there is history information related to the identification information (ID) “1” (step ST808; YES), the mobile object monitoring apparatus 10 voluntarily or via the mobile object monitoring apparatus 200. The history information related to the identification information (ID) “1” is transmitted to (step ST809).

  When there is no history information related to the identification information (ID) “1” (step ST808; NO), the processing returns to step ST804 and the above-described processing is repeated. Thereby, since the monitoring person 3 can acquire the history information and the like of the moving object monitoring apparatus 100 via the data management apparatus 10, it is possible to grasp the current position of the person 1 or estimate the current position. In the second embodiment, the monitoring process is terminated when history information or the like is acquired once. However, the process may be continued.

As described above, even when the roadside monitoring device does not exist, that is, in a situation where the roadside monitoring device does not function as a regional monitoring system, the mobile monitoring device 300 manages the mobile monitoring device 300 managed by the supervisor 3 by monitoring each other. The acquisition information control unit 140 can grasp the past movement position, movement time, movement direction, and movement speed of the person 1 from the history information of the moving object monitoring apparatus 100.
That is, the acquisition information control unit 140 of the mobile object monitoring device 300 uses the history information of the mobile object monitoring device 100 obtained by mutual monitoring between the mobile object monitoring devices, and the current movement state (current position) of the person 1 to be monitored. And the future travel route). For example, if the moving speed of the person 1 to be monitored is equal to or higher than a certain level, the moving means and moving direction of the person 1 can be acquired, so that the destination can be estimated.

  As described above, according to the second embodiment, the position information acquisition unit 110 that acquires the position information of the own device, the identification information storage unit 120 that stores the identification information unique to the mobile object monitoring device, and the mobile object The mobile state information acquisition unit 130 for acquiring element information representing the state of the mobile body, and the mobile body state information including the positional information, identification information of the mobile body monitoring device, and element information representing the state of the mobile body, An acquisition information control unit 140 that creates history information that summarizes information in time series, and a history information storage unit 150 that stores history information of the mobile monitoring device in association with identification information unique to the mobile monitoring device; A wireless communication unit 160 that communicates with an external device, and the acquisition information control unit 140 transmits / receives status information to / from another mobile object monitoring device by the wireless communication unit 160, so that the other mobile object monitoring device Received from If the identification information included in the status information is identification information specific to the mobile monitoring device of the mobile object to be monitored, the history information is received from the mobile monitoring device and stored in the history information storage unit 150. If it is not identification information unique to the mobile object monitoring device of the mobile object to be monitored, identification information unique to the mobile object monitoring device of the mobile object to be monitored is notified to other mobile object monitoring devices. In this way, even in an environment in which the person 1 as the monitoring target mobile body cannot capture the current position or in an environment where the mobile communication network cannot be used due to radio wave environment, the mobile monitoring device is in a mutually moving state. By monitoring the above, it is possible to grasp the past movement state of the person 1 to be monitored.

  Further, according to the second embodiment, the identification information included in the status information received by the wireless communication unit 160 by the acquisition information control unit 140 is identification information unique to the mobile body monitoring device of the mobile body to be monitored. In some cases, the wireless communication unit 160 notifies the status information to a mobile monitoring device different from the mobile monitoring device. In this way, even in an environment in which the person 1 as the monitoring target mobile body cannot capture the current position or in an environment where the mobile communication network cannot be used due to radio wave environment, the mobile monitoring device is in a mutually moving state. Can be monitored.

  Further, according to the second embodiment, the acquisition information control unit 140 receives the identification information unique to the mobile body monitoring device of the mobile body to be monitored newly received by the wireless communication unit 160 as the identification information storage unit 120. When the identification information stored in the identification information storage unit 120 is stored in the identification information storage unit 120 as identification information unique to the moving body monitoring device of the monitoring target moving body. The mobile monitoring device can be notified sequentially.

  Further, according to the second embodiment, the acquisition information control unit 140 receives the identification information unique to the mobile body monitoring device of the mobile body to be monitored newly received by the wireless communication unit 160 as the identification information storage unit 120. If it does not match the identification information stored in the history information, the history information including the newly received identification information is searched from the history information storage unit 150, and the history including the identification information newly received in the history information storage unit 150 If there is information, the history information is notified to a moving body monitoring device different from the moving body monitoring device of the moving body to be monitored. By doing in this way, the historical information of the monitoring object mobile body monitoring device can be notified sequentially.

  Further, according to the second embodiment, the acquisition information control unit 140 receives the identification information unique to the mobile body monitoring device of the mobile body to be monitored newly received by the wireless communication unit 160 as the identification information storage unit 120. If it matches the identification information stored in the history information storage unit 150, the history information of the monitoring device mounted or carried on the monitoring target mobile unit stored in the history information storage unit 150 by the wireless communication unit 160 is transferred to the monitoring target. Notification is made to a moving body monitoring apparatus different from the moving body monitoring apparatus. By doing in this way, the historical information of the monitoring object mobile body monitoring device can be notified sequentially.

  Further, according to the second embodiment, the acquisition information control unit 140 estimates the moving state of the moving object from the history information of the moving object monitoring device of the monitoring target moving object received by the wireless communication unit 160. Based on the estimation result, the mobile object (person 1) to be monitored can be easily searched.

Further, the roadside monitoring device 9 is not an essential device in the present system, but suggests that it can be used in a situation where existing road infrastructure facilities exist.

  The mobile body monitoring devices 100 to 300 and 800 are mobile body monitoring devices having the configuration shown in FIG. 1, and the mobile body monitoring device included in the mobile body entering the surrounding communication area and the roadside monitoring device installed in the periphery. Communicate with. In addition, the mobile monitoring device 200 transmits history information indicating a communication history with the mobile monitoring device 100 to the data management device 10. For example, it is assumed to be mounted on a portable terminal such as a cycle computer or a smartphone, or a simple transmission device such as an RFID. On the other hand, it is assumed that the mobile object monitoring device 800 is mounted on a simple transmission device such as an RFID or a mobile terminal such as a smartphone.

  The roadside monitoring device 9 has the same configuration as the moving body monitoring device shown in FIG. 1, and performs bidirectional communication with the moving body monitoring devices 100 to 300 and 800 that run near and directly below the installed position. It is assumed that the storage units 120 and 150 that acquire and register the identification information (ID), state information, or history information of the moving body monitoring device by registering them are provided. The roadside monitoring device 9 reads the information acquired from the mobile monitoring devices 100 to 300 and 800 from the storage units 120 and 150 and transmits the information to the data management device 10. For example, in order to monitor theft of a bicycle, a roadside monitoring device installed in a bicycle parking lot is assumed.

  The data management device 10 is a data management device that is connected to a network (communication line) such as the Internet including a mobile communication network such as a mobile phone, and the status information corresponds to the identification information (ID) of the mobile monitoring device. The registered database shall be managed. For example, when the monitoring target is the bicycle 1 (the moving body 1), the data management device 10 is based on the identification information and the state information of the moving body monitoring device 100 that the bicycle 1 has received from the devices 200 and 300. The movement route and position of the bicycle 1 are monitored. When an abnormality is recognized in the travel route of the bicycle 1, the fact is notified to the mobile monitoring device 300.

  It should be noted that the network connecting the mobile monitoring devices constituting the mobile monitoring system according to the present invention and between the mobile monitoring devices and the data management device 10 is a bidirectional communication line that can be transmitted and received between the devices. Good. That is, the mobile monitoring system according to the present invention can be configured using any communication network having such a function. In particular, the network is not limited to an existing specific communication network, and a plurality of communication networks can be linked. Moreover, although the data management apparatus 10 has the database, the roadside monitoring apparatus 9 may have the database.

  The moving body 3 refers to a supervisor who monitors the theft of the bicycle 1 (moving body 1). Hereinafter, the moving body 3 is appropriately described as the supervisor 3. The mobile monitoring device 300 is realized by a communication terminal equipped with a connectable browser such as a computer terminal such as a personal computer or a mobile phone. By connecting the mobile monitoring device 300 to the data management device 10, it is possible to monitor the state of the mobile monitoring device 100 of the bicycle 1. When the data management device 10 finds an abnormality in the moving body monitoring device 100, the moving body monitoring device 300 possessed by the monitor 3 alerts the abnormality of the moving body monitoring device 100 possessed by the bicycle 1 using sound and images. Can be notified. The moving body 8 indicates a thief who steals the bicycle 1. Hereinafter, the moving body 8 is appropriately described as a thief 8.

Next, the operation will be described.
(1) Monitoring process of the bicycle 1 using the roadside monitoring device 9 FIG. 10 is a flowchart showing an example of the monitoring process using the roadside monitoring device by the mobile monitoring system according to the third embodiment. 2 shows an example of a mobile body monitoring process performed using the roadside monitoring device 9 that constitutes the mobile body monitoring system according to FIG. Here, the bicycle 1 is monitored using the roadside monitoring device 9 present in the bicycle parking lot.

  First, when the supervisor 3 locks the bicycle 1 in the bicycle parking lot, the movement state information acquisition unit 130 of the moving body monitoring device 100 detects the locking of the bicycle 1 and outputs the detection result to the acquisition information control unit 140. When the acquisition information control unit 140 inputs a detection result indicating that the bicycle 1 is locked, the wireless communication unit 160 uses the wireless communication unit 160 and the identification information (ID) “1” of the device 100 to monitor itself. Is notified to the roadside monitoring device 9 (step ST1001). The monitoring person 3 may notify the roadside monitoring device 9 of the identification information (ID) “1” of the moving body monitoring device 100 using the moving body monitoring device 300.

Next, the acquisition information control unit 140 of the roadside monitoring device 9 registers the identification information (ID) “1” received via the wireless communication unit 160 in the identification information storage unit 120 as a monitoring target (step ST1002).
Thereafter, the acquisition information control unit 140 of the roadside monitoring device 9 monitors the storage content of the identification information storage unit 120 to check whether or not the mobile object monitoring device 100 is continuously monitored (step ST1003). . Here, when the moving body monitoring apparatus 100 is not a monitoring target (step ST1003; NO), the monitoring process is terminated.
On the other hand, when the moving body monitoring device 100 is continuously monitored (step ST1003; YES), the acquisition information control unit 140 of the roadside monitoring device 9 is constant with the moving body monitoring device 100 using the wireless communication unit 160. It is confirmed whether or not the bicycle 1 exists in the communication area of the roadside monitoring device 9 by performing communication at a cycle (step ST1004). When the moving body monitoring device 100 exists in the communication area of the roadside monitoring device 9 (step ST1004; YES), the processing returns to step ST1003 and the monitoring processing is continued.

  Here, an example of preventing the theft of the bicycle 1 by being present in the communication area of the roadside monitoring device 9 has been shown, but it is determined whether or not the traveling speed or cadence information of the bicycle 1 is “0”. May be substituted. When the mobile body monitoring devices 100 and 300 are present in the communication area of the roadside monitoring device 9 and the bicycle 1 is unlocked, the supervisor 3 determines that the bicycle 1 has been unlocked and performs monitoring. Exclude from the target. Further, the mobile object monitoring device 100 or the mobile object monitoring device 300 may determine whether or not it exists in the communication area (nearby).

When the moving body monitoring device 100 does not exist in the communication area of the roadside monitoring device 9 (step ST1004; NO), the acquisition information control unit 140 of the roadside monitoring device 9 identifies that the monitored bicycle 1 has been stolen. The information (ID) “1” is transmitted to the data management apparatus 10 (step ST1005).
Thereafter, the data management device 10 searches the registered contents of the database, collates whether or not the monitor 3 is the owner of the bicycle 1, and monitors the mobile body to each device including the mobile body monitoring device 300. It is notified that apparatus 100 is a monitoring target (step ST1006).
Thereby, the monitoring person 3 can recognize the theft of the bicycle 1 via the moving body monitoring device 300, and the history information via the roadside monitoring device 9 when the bicycle 2 is parked or the history information of the bicycle 1a, It is possible to acquire past identification information (ID) “1”, position information P1, time information T1, and state information S1 (here, acquisition of cadence information can be expected) of the mobile monitoring device 100.

By using communication with the roadside monitoring device 9 as described above, it can be determined whether or not there is a monitoring target moving body in the communication area. Therefore, when the monitoring target mobile body deviates from the communication area, it is possible to find an abnormality such as theft of the mobile body.
In addition, since the mobile body monitoring devices monitor each other, the acquisition information control unit 140 of the mobile body monitoring device 300 managed by the supervisor 3 uses the history information of the mobile body monitoring device 100 to monitor the bicycle 1 to be monitored. The past movement route, movement time, movement direction, and movement speed of the bicycle 1 are grasped, and the current movement state of the monitored bicycle 1 is estimated from these pieces of information.
In the above-described example, the acquisition information control unit 140 of the moving object monitoring apparatus 300 estimates the movement status of the bicycle 1 after theft (after notification of theft) from the cadence information and the movement speed information. Thus, the bicycle 1 can be easily searched for by estimating the movement state of the bicycle 1 after theft.

(2) Bicycle 1 monitoring process not using the roadside monitoring device 9 (part 1)
FIG. 11 is a flowchart illustrating an example of a monitoring process that does not use the roadside monitoring device by the mobile body monitoring system according to the third embodiment, and uses the roadside monitoring device 9 that configures the mobile body monitoring system according to the third embodiment. An example of the mobile body monitoring process that is performed without performing the operation is shown. Here, the bicycle 1 is monitored without using the roadside monitoring device 9 present in the bicycle parking lot.

  First, the supervisor 3 locks the bicycle 1 in the communication area of the mobile monitoring device 300 (step ST1101). The movement state information acquisition unit 130 of the moving body monitoring apparatus 100 detects the locking of the bicycle 1 and outputs the detection result to the acquisition information control unit 140. When the acquisition information control unit 140 inputs a detection result indicating that the bicycle 1 is locked, the acquisition information control unit 140 notifies the mobile monitoring device 300 of the identification information (ID) “1” of the device 100 using the wireless communication unit 160. Next, the acquisition information control unit 140 of the mobile monitoring device 300 registers the identification information (ID) “1” received by the wireless communication unit 160 in the identification information storage unit 120 as a monitoring target (step ST1102).

Thereafter, the acquisition information control unit 140 of the mobile object monitoring device 300 monitors the storage contents of the identification information storage unit 120 to confirm whether or not the mobile object monitoring device 100 is continuously monitored (step ST1103). ). Here, when the moving body monitoring apparatus 100 is not a monitoring target (step ST1103; NO), the monitoring process is terminated.
On the other hand, when the moving body monitoring device 100 is continuously monitored (step ST1103; YES), the acquisition information control unit 140 of the moving body monitoring device 300 is constant with the moving body monitoring device 100 via the wireless communication unit 160. It is confirmed whether or not the bicycle 1 exists in the communication area of the moving object monitoring device 300 by performing communication at a cycle (step ST1104). When the moving body monitoring apparatus 100 exists in the communication area of the moving body monitoring apparatus 300 (step ST1104; YES), the process returns to the process of step ST1103 and the monitoring process is continued.

Here, an example of preventing the bicycle 1 from being stolen by being present in the communication area of the mobile monitoring device 300 has been described, but it is determined whether or not the traveling speed or cadence information of the bicycle 1 is “0”. Thus, it may be determined that the bicycle 1 is not moving, that is, not stolen. When the supervisor 3 unlocks the bicycle 1, that is, when the bicycle 1 is unlocked in a situation where the mobile monitoring device 100 exists in the communication area of the mobile monitoring device 300, the supervisor 3 It is determined that the bicycle 1 is unlocked and is excluded from the monitoring target.
When the moving body monitoring apparatus 100 does not exist in the communication area of the moving body monitoring apparatus 300 (step ST1104; NO), the acquisition information control unit 140 of the moving body monitoring apparatus 300 is a monitoring target using the wireless communication section 160. The fact that the bicycle 1 has been stolen is transmitted to the data management apparatus 10 together with the identification information (ID) “1” (step ST1105).

  Thereafter, the data management device 10 searches the registered contents of the database, collates whether or not the monitor 3 is the owner of the bicycle 1, and monitors the mobile body to each device including the mobile body monitoring device 300. It is notified that apparatus 100 is a monitoring target (step ST1106). Thereby, the monitoring person 3 can recognize the theft of the bicycle 1 via the moving body monitoring apparatus 300, and the moving body monitoring transmitted via the moving body monitoring apparatus 800 or the moving body monitoring apparatus 800 of the bicycle 1a. Based on the history information of the device 200, identification information (ID) “1”, position information P1, time information T1, and state information S1 (here, acquisition of cadence information can be expected) when approaching the mobile monitoring device 100. It can be acquired.

As described above, it is possible to grasp the movement of the monitoring target moving body in the communication area by grasping the change in the state information of the moving body monitoring apparatus or the communication availability of each moving body monitoring apparatus. Therefore, when it is detected that the monitored mobile body has deviated or moved from the communication area, it is possible to find an abnormality such as theft of the mobile body.
In addition, since the mobile body monitoring devices monitor each other, the acquisition information control unit 140 of the mobile body monitoring device 300 managed by the monitor 3 can determine the past information of the bicycle 1 from the history information of the mobile body monitoring device 100. The travel route, travel time, travel direction, and travel speed are grasped, and the current travel state of the monitored bicycle 1 is estimated from these information.
In the above-described example, the acquisition information control unit 140 of the moving object monitoring apparatus 300 estimates the movement status of the bicycle 1 after theft (after notification of theft) from the cadence information and the movement speed information. Thus, the bicycle 1 can be easily searched for by estimating the movement state of the bicycle 1 after theft.

(3) Bicycle 1 monitoring process not using the roadside monitoring device 9 (part 2)
FIG. 12 is a flowchart showing another example of the monitoring process that does not use the roadside monitoring device by the mobile body monitoring system according to the third embodiment, and the roadside monitoring device 9 constituting the mobile body monitoring system according to the third embodiment. The moving body monitoring process performed without using is shown. Here, an example in which the thief 8 monitors the bicycle 1a when stealing the bicycle 1a equipped with the moving body monitoring device 800 is shown.

  First, the acquisition information control unit 140 of the mobile monitoring device 100 uses the wireless communication unit 160 to search for another mobile monitoring device that exists within its own communication area (step ST1201). As a result of this search, when another mobile monitoring device existing in its own communication area cannot be detected (step ST1201; NO), the wireless communication unit 160 of the mobile monitoring device 100 uses the ad hoc mode (for example, WAVE communication). ) To the infrastructure mode (for example, WiFi communication) (step ST1202). Here, it is only necessary to change the current communication method, and the infrastructure mode may be changed to the ad hoc mode.

  Thereafter, the acquisition information control unit 140 of the mobile monitoring device 100 again searches for another mobile monitoring device existing in its own communication area using the wireless communication unit 160 (step ST1203). As a result of this search, when another mobile monitoring device existing in its own communication area cannot be detected (step ST1203; NO), the process returns to step ST1202 and the above-described processing is repeated.

  When the mobile object monitoring device 800 existing in its own communication area can be detected (step ST1201; YES or step ST1203; YES), the acquisition information control unit 140 of the mobile object monitoring device 100 determines the mobile object monitoring device 800. Is acquired and stored in the history information storage unit 150 (step ST1204). Since the mobile monitoring device 800 cannot use a communication method related to the ad hoc mode or a difference in mounting form or the like is considered, the communication method is switched to cope with a variety of communication methods.

As described above, even when the mobile monitoring device cannot acquire information using a specific communication method, information may be acquired by switching to a different communication method, and more information is expected to be acquired. The Therefore, even if the discovery of the theft of the bicycle 1a is delayed, if the history information of the bicycle 1a is acquired, it is possible to guess the theft.
In the above example, switching from WAVE communication to WiFi communication can be expected to establish communication with the mobile monitoring device 800 mounted on the bicycle 1a stolen by the thief 8. In addition, when the mobile body monitoring apparatus 100 and the mobile body monitoring apparatus 800 exist in the same vehicle, it is not always necessary to use the WAVE communication. If the WiFi function is used, it is also used in various existing devices such as a portable terminal. it can.

(4) Monitoring process of the bicycle 1 that does not use the roadside monitoring device 9 (part 3)
FIG. 13 is a flowchart illustrating still another example of the monitoring process that does not use the roadside monitoring device by the mobile body monitoring system according to the third embodiment, and configures the mobile body monitoring system according to the third embodiment. 9 shows a moving body monitoring process that is performed without using 9. Here, an example in which the thief 8 monitors the bicycle 1a when stealing the bicycle 1a equipped with the moving body monitoring device 800 is shown. Note that the mobile monitoring device 200 is not a monitoring target.

  First, the acquisition information control unit 140 of the mobile object monitoring device 200 searches for another mobile object monitoring device existing in its own communication area using the wireless communication unit 160 (step ST1301). As a result of this search, when another mobile monitoring device existing in its own communication area can be detected (step ST1301; YES), the wireless communication unit 160 of the mobile monitoring device 200 performs carrier wave sensing. Then, the communication of the other mobile monitoring device is confirmed (step ST1302). Here, it is assumed that the moving object monitoring apparatus 800 has been detected.
