The edge device 110 mediates data communication between a device connected to the communication network 150 and a device connected to the communication network 160. The communication network 150 may include the Internet, for example. The communication network 150 is connected to an external server 120 for obtaining information about traffic accidents and disclosing the information to many drivers. A specific example of the external server 120 is a traffic information server that is operated and managed by a road administrator such as a prefecture, the Ministry of Land, Infrastructure, Transport and Tourism, or their agency.

  In the communication network 150, characteristic information (in other words, information that characterizes the event) representing the characteristics of the image captured by the IoT device 140 when a specific event (event) such as the occurrence of a traffic accident is detected. The drive recorder information server 130 that acquires the position information indicating the occurrence position and the time information indicating the occurrence time from the edge device 110 is connected. In the present embodiment, the drive recorder information server 130, based on the information acquired from the edge device 110, accident summary information indicating an outline of a traffic accident that has occurred (information indicating a degree of a traffic accident, an occurrence position, and an occurrence time). ) Is generated and provided to the external server 120. As a result, many drivers who use the external server 120 can share information regarding traffic accidents. In the following, the edge device 110 and the drive recorder information server 130 that show the features of the present embodiment will be mainly described.

  As shown in FIG. 2, the edge device 110 includes a processor 111, a memory 112, a storage 113, and a communication device 114. These devices are connected via a bus 115. The processor 111 executes various processes by reading the program into the memory 112 and executing the program. For example, the processor 111 may be configured by a CPU (Central Processing Unit). The memory 112 stores the program executed by the processor 111. For example, the memory 112 may be configured by a ROM (Read Only Memory) or a RAM (Random Access Memory). The storage 113 stores various data and programs. For example, the storage 113 may be composed of a hard disk drive or a flash memory. The communication device 114 performs data communication via the communication network 150 or the communication network 160.

In other words, the detection unit 212 is a second control unit that controls the image sensor module so as to detect that the person has performed a predetermined action based on the image. Note that the predetermined event means a collision accident (that is, a traffic accident) between a vehicle on which the edge device 110 is mounted and another vehicle, an object such as a wall or a telephone pole, or a person or an animal. Here, the following methods can be considered as specific methods for detecting the occurrence of a traffic accident. First, for each of a plurality of types of traffic accidents, the characteristic information extracted from the image recorded by the drive recorder when the accident occurs is stored in advance in the storage 113 as the determination reference information. Then, the detection means 212 compares the feature information extracted by the extraction means 211 with each of the plurality of pieces of determination reference information, and determines that a traffic accident has occurred when the same or similar determination reference information exists. Just do it. Note that the same or similar determination of the characteristic information and the determination reference information is performed according to the distance between the points when the former and the latter are mapped as points in the same coordinate space (for example, multidimensional Euclidean space). A mode for making a determination is possible.

  In the present embodiment, the occurrence of a predetermined event is detected based on the characteristic information extracted by the extraction unit 211, but the occurrence of the predetermined event is detected by performing pattern recognition on the image captured by the image capturing unit 215.

Further, an acceleration sensor or an impact sensor is connected to the edge device 110 via the communication network 160, and the measurement result of each sensor (that is, a change in acceleration of a vehicle equipped with the edge device 110 or an impact applied to the vehicle). The occurrence of a traffic accident may be detected in consideration of the above.

  The transmission unit 213 is triggered by the detection of a predetermined event (a traffic accident in the present embodiment) by the detection unit 212, and the feature information extracted by the extraction unit 211 for the image in which the predetermined event is detected, The position information indicating the position where the image was captured and the time information indicating the time when the image was captured are transmitted to the drive recorder information server 130 via the communication unit 214. In other words, the transmission unit 213 provides the acquisition unit of the drive recorder information server 130 via the communication network with the characteristic information, the position information, and the time information triggered by the detection of the predetermined event. It is an interference means that interferes with the host controller of the drive recorder.

  Below, a set of the characteristic information, the position information, and the time information is referred to as “drive recorder information”. The position information may be acquired by using GPS, a beacon of a wireless access point in the communication network 150, or the time information may be acquired by using GPS, a real-time clock, or the like. Further, the communication address of the drive recorder information server 130, which is the destination of the drive recorder information, may be written in the storage 113 in advance, or may be embedded in the program.

The drive recorder information server 130 includes an acquisition unit 231, a provision unit 232, a payment unit 233, and a communication unit 234. The communication means 234 is the communication device 134 in FIG. The acquisition unit 231, the payment unit 233, and the provision unit 232 in FIG. 5 cooperate with the program stored in the memory 132 or the storage 133 and the processor 131 that executes the program so that the processor 131 performs calculation or communication. It is a software module realized by controlling the means 234 (communication device 134).

  The acquisition unit 231 acquires the drive recorder information from the edge device 110 via the communication network 150. In the present embodiment, the acquisition unit 231 acquires the drive recorder information by receiving the drive recorder information transmitted via the communication network 150. In the present embodiment, the drive recorder information is transmitted from the edge device 110 to the drive recorder information server 130 via the communication network 150 upon detection of a traffic accident by the detection means 212, but from the drive recorder information server 130. The drive recorder information may be acquired by polling. The acquisition unit 231 in this case is a unit that periodically performs the polling.

  The providing unit 232 generates accident summary information from the drive recorder information acquired by the acquiring unit 231 and transmits it to the external server 120. More specifically, the providing unit 232 determines, based on the characteristic information included in the drive recorder information acquired by the acquiring unit 231, the degree of the traffic accident (a serious accident that requires the vehicle to be closed thereafter, an accident occurrence). A moderate accident that requires traffic regulation such as deceleration when passing near the location, a minor accident that does not require traffic regulation but requires attention to the surroundings when passing near the location where the accident occurred) judge.

  Then, the providing unit 232 transmits the information indicating the degree of the traffic accident, the position information and the time information included in the drive recorder information to the external server 120 as the accident summary information. According to such an aspect, it is not necessary for the external server 120 side to judge the degree of the traffic accident, and the accident summary information provided from the drive recorder information server 130 is shared as it is with a large number of drivers, thereby making the situation worse. Can be prevented. As a specific method of determining the degree of traffic accident based on the characteristic information, determination criterion information indicating a range of characteristic information (or typical characteristic information) for each degree of traffic accident is stored in the storage 133 in advance. Then, a method of determining the degree of the traffic accident by comparing the characteristic information included in the drive recorder information acquired by the acquisition unit 231 with the determination reference information can be considered.

  The payment means 233 calculates the reward paid to the administrator of the vehicle provided with the imaging device that has captured the image that is the source of the information provided to the external server 120, and pays the reward. In the present embodiment, in the storage 133, the transfer destination information (for example, a bank account number) of the administrator of the vehicle that has signed the information provision contract with the operation administrator of the drive recorder information providing system 100 is the vehicle. It is stored in advance in association with the communication address of the edge device 110 mounted on the. Then, the payment unit 233 transfers the reward to the transfer destination indicated by the transfer destination information corresponding to the communication address of the transmission source of the drive recorder information acquired by the acquisition unit 231. It should be noted that, in addition to the transfer of the reward, a notification to the effect that the reward has been transferred may be transmitted to the information provider.

  With respect to the remuneration to be paid to the sender of the drive recorder information, a calculation formula for the consideration of information provision may be set in a contract regarding information provision, and the compensation may be calculated according to the calculation formula. Specific examples of this calculation formula include a calculation formula in which the higher the rarity of characteristic information (for example, the seriousness of an accident), the higher the consideration, and a calculation formula in which the higher the number of times the drive recorder information is provided, the higher the consideration. Be done. According to these aspects, it is possible to give the vehicle manager an incentive to provide the drive recorder information, and raise the interest of the manager in providing the information. It should be noted that the payment of the reward may be performed each time information is provided, or for example, the reward generated during the certain period may be collectively paid for each certain period such as monthly.

<2. Operation>
Next, the operation of each device included in the drive recorder information providing system 100 will be described with reference to FIG. FIG. 6 is a sequence diagram showing operations of the edge device 110 and the drive recorder information server 130 included in the drive recorder information providing system 100.

In step SA100, the extraction unit 211 analyzes the image data provided from the imaging unit 215 and extracts the characteristic information. Step SA110 following step SA100 is a process executed by the detection unit 212 of the edge device 110. In step SA110, the detection unit 212 detects a predetermined event (traffic accident) based on the characteristic information provided by the extraction unit 211.

  Step SA120 subsequent to step SA110 is a process executed by the transmission unit 213 of the edge device 110. In step SA120, the transmission unit 213 transmits the drive recorder information including the characteristic information extracted by the extraction unit 211 for the image in which the predetermined event is detected by the detection unit 212 to the drive recorder information server 130. The drive recorder information transmitted from the edge device 110 in this way is transmitted to the drive recorder information server 130 via the communication network 150.

  As shown in FIG. 6, the drive recorder information server 130 executes the processing from step SB100 onward when the drive recorder information is received via the communication network 150. Step SB100 in FIG. 6 is a process executed by the acquisition unit 231 of the drive recorder information server 130. In step SB100, the acquisition unit 231 acquires the drive recorder information transmitted from the edge device 110.

  Step SB110 subsequent to step SB100 is a process executed by the providing unit 232 of the drive recorder information server 130. In step SB110, the providing unit 232 transmits the accident summary information generated based on the drive recorder information acquired in step SB100 to the external server 120. The accident summary information thus transmitted from the drive recorder information server 130 is transmitted to the external server 120 via the communication network 150. The external server 120 makes the accident summary information received via the communication network 150 public (for example, posted on a predetermined web page or broadcast on a radio or the like). From this, many drivers share the above accident summary information, and when passing near the location of the accident immediately after the accident indicated by the accident summary information, detour to another road, according to traffic regulations. Depending on the extent of the traffic accident that occurred, such as slowing down the vehicle and passing it while paying attention, it is possible to deal with the situation worsening (congestion caused by the traffic accident or secondary traffic The occurrence of accidents) can be prevented.

  Step SB120 subsequent to step SB110 is a process executed by the payment means 233 of the drive recorder information server 130. In this step SB120, the payment means 233 calculates the remuneration to be paid to the manager of the vehicle provided with the imaging device that has taken the image that is the source of the information provided to the external server 120, and pays the remuneration. As a result, an incentive for providing the drive recorder information can be given to the vehicle administrator, and the administrator's interest in providing the information can be increased. In the present embodiment, the process of step SB120 is executed after the process of step SB110, but the process of step SB120 may be executed first, and then the process of step SB110 may be executed.

  As described above, according to the drive recorder information providing system 100 of the present embodiment, it is possible to acquire information regarding a traffic accident from a plurality of vehicles using IoT and provide the external system with the information.

Therefore, according to the present embodiment, the image data captured by the IoT device 140 is transmitted to the drive recorder information server 130, and the image data is analyzed by the drive recorder information server 130 as compared with the communication mode. The amount of data transmitted from the edge device 110 to the drive recorder information server 130 via the network 150 can be reduced. Further, since data transmission from the edge device 110 to the drive recorder information server 130 is performed only when a predetermined event is detected, communication is performed in comparison with a mode in which data transmission from the edge device 110 to the drive recorder information server 130 is always performed. The amount of data transmitted from the edge device 110 to the drive recorder information server 130 via the network 150 can be further reduced.

  Further, according to the present embodiment, the processing load of the drive recorder information server 130 can be reduced and the response of the drive recorder information server 130 can be reduced as compared with the mode in which the image data is analyzed by the drive recorder information server 130.
