  On the toll road, a dedicated lane for using an ETC (Electronic Toll Collection System) that automatically collects tolls is provided. However, some of the vehicles that use this dedicated lane are illegal vehicles that do not have an ETC on-board unit, but do not pay tolls, destroying the blocking rod provided at the gate and escaping. Exists. Therefore, as a technology related to such a background, there is known a technology for identifying an unauthorized vehicle by capturing an image of the vehicle with an imaging device when a blocking rod is destroyed in order to monitor such an unauthorized vehicle. (For example, refer to Patent Document 1).

  As another technique, when a vehicle detection device provided in front of the gate detects the entry of the vehicle, when the vehicle is imaged by the imaging device and there is a malfunction in the billing result at the gate, A technique is known in which an unauthorized vehicle is identified by recording a charge result in association with each other.

  However, in the technique described in Patent Document 1 described above, since the vehicle is imaged at the time when the blocking bar is destroyed, it becomes impossible to monitor a subsequent vehicle passing through the gate after the blocking bar is broken. There is a problem that it becomes difficult to accurately identify an unauthorized vehicle.

  Further, in the other technology described above, since the image is taken in front of the gate and the charging result is confirmed at the gate, while the vehicle moves from the position of the vehicle detection device to the position of the gate, The vehicle does not necessarily enter the gate in the order detected by the vehicle detection device, such as being switched. Therefore, in this technique, it is difficult to strictly manage the order of vehicles detected by the vehicle detection device and the order of vehicles entering the gate. As a result, in this technique, there is a problem that it becomes difficult to associate a charging result with an image, and it is difficult to accurately identify an unauthorized vehicle. Various techniques are known as techniques related to such a background (see, for example, Patent Document 2).

  The unauthorized traffic imaging system described in Patent Literature 2 communicates with a vehicle-mounted device and acquires vehicle-mounted device information. And this unauthorized traffic imaging system image | photographs a vehicle using the completion of communication with onboard equipment as a trigger, and produces | generates imaging data. The unauthorized traffic imaging system stores the captured image data and the vehicle-mounted device information in association with each other when the charge result based on the vehicle-mounted device information becomes abnormal. Thus, depending on the unauthorized traffic imaging system, the captured image of the vehicle can be easily associated with the vehicle information, and the unauthorized vehicle can be identified easily and accurately.

  However, in the mobile charging system as described in Patent Document 2, as represented by an ERP (Electronic Load Pricing) system implemented in Singapore, vehicle information of vehicles traveling in the charging zone It is necessary to provide a vehicular sensor for acquiring the radio frequency and a radio device for DSRC (Dedicated Short Range Communications) communication in a large-scale structure such as a gantry. For this reason, in such a mobile charging system, since a large amount of construction costs are required for construction, it is strongly desired to reduce the construction costs. Various techniques are known as techniques related to such a background (see, for example, Patent Document 3).

  Patent Document 3 describes a mobile charging method that realizes a reduction in construction costs. In this mobile charging method, a vehicle-mounted device that stores a charging zone that is attached to a mobile device and indicates a region to be charged, and vehicle-mounted device identification information that is assigned to individually identify the vehicle-mounted device is a GPS (Global It recognizes that it has entered the billing zone based on the position information obtained by the Positioning System) function. In this mobile charging method, the local computer system generates shooting data by shooting a moving body image in the charging zone. In this mobile charging method, the center computer system receives the mobile image from the local computer. This mobile charging method extracts and stores license plate information from the mobile image. In this mobile charging method, when the vehicle-mounted device enters the charging zone, the transaction information including the vehicle-mounted device identification information is transmitted to the authentication computer of the center side computer system by wireless communication at a predetermined timing. And this mobile body charging method is for the authentication computer to charge the mobile body equipped with the on-vehicle device based on the comparison between the on-vehicle device identification information received from the on-vehicle device and the identification information registered in advance. Authenticate. In this way, depending on this mobile charging method, it is not necessary to install a large-scale structure such as a gantry in which a roadside device for acquiring vehicle information of a vehicle traveling in the charging zone is required, thereby reducing construction costs. Can be realized.

  10 to 13 show an example of an operation flow of the vehicle data processing device 110. FIG. In the description of this operation flow, a process for associating the second vehicle data with the first vehicle data will be described in detail. In the description of this operation flow, both FIGS. 1 to 9 are referred to.

  First, the optical character recognition availability determination unit 113 of the vehicle data processing device 110 determines whether or not the character string of the vehicle number indicated by the vehicle number information included in the first vehicle data is recognized as a character. (S301, S311). More specifically, the optical character recognition availability determination unit 113 is a target to which the second vehicle data is associated with the first vehicle data stored in the first vehicle data storage unit 123. The first vehicle data is selected. Then, the optical character recognition availability determination unit 113 reads the vehicle number information of the first vehicle data from the first vehicle data storage unit 123. Then, the optical character recognition availability determination unit 113 determines whether or not the character string of the vehicle number indicated by the vehicle number information is recognized as a character. For example, when a character such as “?” Indicating that the character is not recognized is included in the character string of the vehicle number, the optical character recognition availability determination unit 113 recognizes the portion as a character. Judge that it is not. As a result, when it is determined that all the character strings of the vehicle numbers are recognized as characters (S301: Yes), the optical character recognition availability determination unit 113 identifies the first vehicle data described above. Information on the vehicle data ID is sent to the vehicle number search unit 115.

  When the vehicle number search unit 115 of the vehicle data processing apparatus 110 receives the information on the first vehicle data ID sent from the optical character recognition availability determination unit 113, the vehicle number search unit 115 is identified by the information on the first vehicle data ID. The second vehicle data including the same vehicle number information as the vehicle number information included in the first vehicle data is searched (S302). More specifically, the vehicle number search unit 115 uses information on the vehicle number associated with the information on the first vehicle data ID received from the optical character recognition availability determination unit 113 as the first vehicle data storage unit. Read from 123. Then, the vehicle number search unit 115 searches the second vehicle data storage unit 124 for information on the vehicle number having the same character string as the character string of the vehicle number indicated by the vehicle number information. As a result, when information on the same vehicle number is searched (S303: Yes), the vehicle number search unit 115 reads information on the second vehicle data ID associated with the information on the vehicle number. Then, the vehicle number search unit 115 sends the information on the second vehicle data ID and the information on the first vehicle data ID for identifying the first vehicle data to the data association unit 121.

  When the data association unit 121 of the vehicle data processing device 110 receives the information on the first vehicle data ID and the information on the second vehicle data ID sent from the vehicle number search unit 115, the second vehicle data The second vehicle data identified by the ID information is permanently linked to the first vehicle data identified by the first vehicle data ID information. More specifically, the data association unit 121 associates the information of the first vehicle data ID received from the vehicle number search unit 115 with the information of the second vehicle data ID, and the vehicle data storage unit 125. To store. Then, the data association unit 121 deletes the information of the first vehicle data ID and each piece of information associated therewith from the first vehicle data storage unit 123. Further, the data association unit 121 deletes the information of the second vehicle data ID and each piece of information associated therewith from the second vehicle data storage unit 124.

  As described above, when there is second vehicle data including the information of the same vehicle number as the information of the vehicle number of the first vehicle data, the vehicle data processing device 110 converts the second vehicle data to the first vehicle data. This is linked to the data. This is because when the vehicle number of the license plate of the vehicle imaged by the monitoring camera 130 matches the vehicle number included in the data received from the vehicle-mounted device of the vehicle, both data are certainly data of the same vehicle. Because it is considered.

  On the other hand, when the information of the same vehicle number is not searched as a result of the search in the above step S302 (S303: No), the vehicle number search unit 115 is the first vehicle data for identifying the first vehicle data. The ID information is sent to the overlapping range search unit 116.

  Upon receiving the information on the first vehicle data ID sent from the vehicle number search unit 115, the overlapping range search unit 116 of the vehicle data processing apparatus 110 is identified by the information on the first vehicle data ID. The second information including the roadside wireless device ID information for identifying the roadside wireless device 140 having the communication range C overlapping the imaging range A of the monitoring camera 130 indicated by the information of the monitoring camera ID included in the one vehicle data. Vehicle data is searched (S306). More specifically, the overlapping range search unit 116 uses the first vehicle data storage unit 123 as information on the monitoring camera ID associated with the information on the first vehicle data ID received from the vehicle number search unit 115. Read from. Then, the overlapping range search unit 116 identifies roadside wireless device ID information for identifying the roadside wireless device 140 having the communication range C overlapping the imaging range A of the monitoring camera 130 identified by the information of the monitoring camera ID. The second vehicle data storage unit 124 is searched. As a result, when the information on the corresponding roadside wireless device ID is searched (S307: Yes), the overlapping range search unit 116 obtains the information on the second vehicle data ID associated with the information on the roadside wireless device ID. read out. Then, the vehicle number search unit 115 uses the vehicle type category search unit 118 and the travel restriction information on the information on the second vehicle data ID and the information on the first vehicle data ID for identifying the first vehicle data. Send to search unit 119.

  Upon receiving the information on the first vehicle data ID and the information on the second vehicle data ID sent from the overlapping range search unit 116, the vehicle type classification search unit 118 of the vehicle data processing device 110 receives the second vehicle data ID. Of the second vehicle data identified by each information of the data ID, information on the vehicle type classification different from the information on the vehicle type classification included in the first vehicle data identified by the information of the first vehicle data ID. The second vehicle data including is searched (S308). More specifically, the vehicle type category search unit 118 obtains vehicle type category information associated with the first vehicle data ID information received from the overlapping range search unit 116 from the first vehicle data storage unit 123. read out. The vehicle type category search unit 118 is associated with the information on the second vehicle data ID received from the overlapping range search unit 116, and is different from the vehicle type category information read from the first vehicle data storage unit 123. Search for category information. For example, when the information on the vehicle type division read from the first vehicle data storage unit 123 is “ordinary vehicle”, the vehicle type division search unit 118 searches for information on the vehicle type division other than “normal vehicle”. As a result, when information on the corresponding vehicle type division is searched (S309: Yes), the vehicle type division search unit 118 reads information on the second vehicle data ID associated with the information on the vehicle type division. Then, the vehicle type category search unit 118 sends the information on the second vehicle data ID and the information on the first vehicle data ID for identifying the first vehicle data to the data association unit 121.

  When the travel restriction search unit 119 of the vehicle data processing device 110 receives the information on the first vehicle data ID and the information on the second vehicle data ID sent from the overlapping range search unit 116, the second vehicle From the second vehicle data identified by the information of the data ID, the second vehicle data including the information on the travel restriction (Yes or No) that does not receive the travel restriction on the toll road R is searched (S308). . More specifically, the travel restriction search unit 119 determines the toll road from the travel restriction (Yes or No) information associated with the information on the second vehicle data ID received from the overlapping range search unit 116. Search for information on values not subject to R travel restrictions. For example, when a travel restriction that restricts the passage of the toll road R during a predetermined time is performed and the current time is within the predetermined time, the travel restriction search unit 119 sets the travel restriction (Yes or No) No) information is searched. As a result, when the information on the corresponding travel restriction (Yes or No) is searched (S309: Yes), the travel restriction search unit 119 displays the second information associated with the information on the travel restriction (Yes or No). Read the vehicle data ID information. Then, the travel restriction search unit 119 sends the information on the second vehicle data ID and the information on the first vehicle data ID for identifying the first vehicle data to the data association unit 121. In addition, the travel restriction search unit 119 sends information on the first vehicle data ID for identifying the first vehicle data to the enforcement target determination unit 120.

  On the other hand, when receiving the information on the first vehicle data ID sent from the travel restriction search unit 119, the control object determination unit 120 of the vehicle data processing apparatus 110 is identified by the information on the first vehicle data ID. Based on the information on the vehicle number of the vehicle included in the one vehicle data, it is determined whether or not the vehicle is a target of control (S310). More specifically, the control target determination unit 120 uses the first vehicle data storage unit as the vehicle number information of the vehicle associated with the first vehicle data ID information received from the travel restriction search unit 119. 123. And the control object determination part 120 determines whether the vehicle is a control object based on the information of the vehicle number of the vehicle. For example, the control target determination unit 120 refers to a list of vehicle numbers of the vehicles to be controlled and determines whether or not the vehicle is a control target. Then, the control target determination unit 120 sends information on the determination result to the data association unit 121.

  The data association unit 121 is sent from the vehicle type category search unit 118 and the travel restriction search unit 119, the first vehicle data ID information, the second vehicle data ID information, and the enforcement target determination unit 120. When the information of the determination result is received, the second vehicle data identified by the information of the second vehicle data ID is temporarily linked to the first vehicle data identified by the information of the first vehicle data ID. (S304). At that time, the data association unit 121 associates the determination result information received from the enforcement target determination unit 120 together. More specifically, the data association unit 121 associates the information on the first vehicle data ID received from the vehicle type category search unit 118 and the travel restriction search unit 119 with the information on the second vehicle data ID. And stored in the vehicle data storage unit 125. In addition, the data association unit 121 further associates the determination result information received from the enforcement target determination unit 120 and stores the information in the vehicle data storage unit 125. Then, the data association unit 121 deletes the information of the first vehicle data ID and each piece of information associated therewith from the first vehicle data storage unit 123. In this case, the data association unit 121 does not delete the information on the second vehicle data ID and the information associated therewith from the second vehicle data storage unit 124.

  Thus, when there is no second vehicle data that includes the same vehicle number information as the vehicle number information of the first vehicle data, the vehicle data processing device 110 is the vehicle type classification information of the first vehicle data. Second vehicle data that includes information on different vehicle types and includes information on travel restrictions (Yes or No) that are not subject to travel restrictions on the toll road R is temporarily associated with the first vehicle data. This is because when a vehicle-mounted device other than a regular vehicle-mounted device is attached to the vehicle, a vehicle-mounted device for a vehicle type that has a lower toll than the vehicle type of the vehicle is attached, or traveling on a toll road R This is because there is a high possibility that a vehicle-mounted device that has been set to receive no restrictions is attached.

  On the other hand, as a result of the search in step S306, if the information of the corresponding roadside wireless device ID is not searched (S307: No), the overlapping range search unit 116 identifies the first vehicle data described above. The vehicle data ID information is sent to the control object determination unit 120 and the data association unit 121.

  Upon receiving the information on the first vehicle data ID sent from the overlapping range search unit 116, the control target determination unit 120 receives the vehicle included in the first vehicle data identified by the information on the first vehicle data ID. Based on the vehicle number information of the vehicle, it is determined whether or not the vehicle is subject to control (S310). Then, the control target determination unit 120 sends information on the determination result to the data association unit 121.

  When the data association unit 121 receives the information on the first vehicle data ID sent from the overlapping range search unit 116 and the information on the determination result sent from the enforcement target determination unit 120, the data association unit 121 receives the first vehicle data ID. The association of the second vehicle data to the first vehicle data is terminated without associating the second vehicle data with the first vehicle data identified by the information (S304). At that time, the data linking unit 121 links the determination result information received from the enforcement target determination unit 120 to the first vehicle data. More specifically, the data association unit 121 associates the information on the first vehicle data ID received from the overlapped range search unit 116 with the information on the determination result received from the enforcement target determination unit 120, and Store in the data storage unit 125. Then, the data association unit 121 deletes the information of the first vehicle data ID and each piece of information associated therewith from the first vehicle data storage unit 123.

  As described above, there is no second vehicle data including information on the roadside apparatus ID for identifying the roadside apparatus 140 having the communication range C overlapping the imaging area A in which the target vehicle of the first vehicle data is imaged. In this case, the data association unit terminates the association of the second vehicle data with respect to the first vehicle data on the assumption that the second vehicle data associated with the first vehicle data does not exist. This is because, when the vehicle is imaged by the monitoring camera 130, if the roadside wireless device 140 having the communication range C overlapping the imaging range A of the monitoring camera 130 does not receive data from the vehicle-mounted device, This is because it is considered that data reception from the vehicle-mounted device has failed or the vehicle-mounted device is not attached.

  On the other hand, as a result of the search in the above step S308, when neither the information of the corresponding vehicle type classification nor the information of the corresponding travel restriction (Yes or No) is searched (S309: No), the vehicle type classification search unit 118 or the travel The restriction search unit 119 sends information on the first vehicle data ID for identifying the first vehicle data to the enforcement target determination unit 120 and the data association unit 121.

  Upon receiving the information on the first vehicle data ID sent from the vehicle type category search unit 118, the control target determination unit 120 receives the vehicle included in the first vehicle data identified by the information on the first vehicle data ID. Based on the vehicle number information of the vehicle, it is determined whether or not the vehicle is subject to control (S310). Then, the control target determination unit 120 sends information on the determination result to the data association unit 121.

  When the data association unit 121 receives the information on the first vehicle data ID transmitted from the vehicle type category search unit 118 and the information on the determination result transmitted from the control target determination unit 120, the data association unit 121 receives the first vehicle data ID. The association of the second vehicle data to the first vehicle data is terminated without associating the second vehicle data with the first vehicle data identified by the information (S304). At that time, the data linking unit 121 links the determination result information received from the enforcement target determination unit 120 to the first vehicle data. More specifically, the data association unit 121 associates the information on the first vehicle data ID received from the vehicle type category search unit 118 with the information on the determination result received from the enforcement target determination unit 120, and Store in the data storage unit 125. Then, the data association unit 121 deletes the information of the first vehicle data ID and each piece of information associated therewith from the first vehicle data storage unit 123.

  As described above, when there is no second vehicle data that includes the same vehicle number information as the vehicle number information of the first vehicle data, the vehicle type classification information different from the vehicle type classification information of the first vehicle data is obtained. When there is no second vehicle data to be included, the vehicle data processing device 110 is suspected of fraud in which no vehicle-mounted device is mounted on the vehicle because there is no second vehicle data associated with the first vehicle data. As a matter of course, the association of the second vehicle data with the first vehicle data is terminated.

  Upon receiving the information on the first vehicle data ID sent from the travel restriction search unit 119, the control object determination unit 120 receives the vehicle included in the first vehicle data identified by the information on the first vehicle data ID. Based on the vehicle number information of the vehicle, it is determined whether or not the vehicle is subject to control (S310). Then, the control target determination unit 120 sends information on the determination result to the data association unit 121.

  When the data association unit 121 receives the information on the first vehicle data ID sent from the travel restriction search unit 119 and the information on the determination result sent from the enforcement target determination unit 120, the data association unit 121 receives the first vehicle data ID. The association of the second vehicle data to the first vehicle data is terminated without associating the second vehicle data with the first vehicle data identified by the information (S304). At that time, the data linking unit 121 links the determination result information received from the enforcement target determination unit 120 to the first vehicle data. More specifically, the data linking unit 121 associates the information on the first vehicle data ID received from the travel restriction search unit 119 with the information on the determination result received from the enforcement target determination unit 120, so that the vehicle Store in the data storage unit 125. Then, the data association unit 121 deletes the information of the first vehicle data ID and each piece of information associated therewith from the first vehicle data storage unit 123.

  In this way, when there is no second vehicle data that includes the same vehicle number information as the vehicle number information of the first vehicle data, the travel limit (Yes or No) is a value that is not subject to travel restrictions on the toll road R. If there is no second vehicle data including the above information, the vehicle data processing device 110 assumes that there is no second vehicle data associated with the first vehicle data, and the second vehicle data for the first vehicle data. End data linking. This is because, when the vehicle-mounted device of the vehicle is illegally replaced, it is considered that there is a high possibility that the vehicle-mounted device for the vehicle type that is cheaper than the vehicle type of the own vehicle is attached.

  On the other hand, when determining whether or not the character string of the vehicle number is recognized as a character, it is determined that a part of the character string of the vehicle number is not recognized as a character (S301: No → S311: Yes), the optical character recognition availability determination unit 113 sends the information of the first vehicle data ID for identifying the first vehicle data to the character complementing unit 114.

  When the character complementing unit 114 of the vehicle data processing device 110 receives the information on the first vehicle data ID sent from the optical character recognition availability determination unit 113, the first vehicle data identified by the information on the vehicle data ID. The character of the part which is not recognized as a character among the character strings of the vehicle number shown by the information of the vehicle number contained in is supplemented (S312). More specifically, the character complementing unit 114 uses information on the vehicle number associated with the information on the first vehicle data ID received from the optical character recognition availability determination unit 113 as the first vehicle data storage unit 123. Read from. And the character complement part 114 complements the character of the part which is not recognized as a character among the character strings of the vehicle number shown by the information of the vehicle number. For example, the character complementing unit 114 compares the character string of the vehicle number with the vehicle number information stored in the second vehicle data storage unit 124, and calculates the degree of coincidence. Then, if the calculated degree of coincidence is equal to or greater than a predetermined threshold, the character complementing unit 114 adds a character of “?” Indicating that the character is not recognized to the second vehicle data storage unit 124. The character is complemented by replacing it with the character of the stored vehicle number. And the character complement part 114 stores the information of the vehicle number which shows the character string of the vehicle number which complemented the character of the part which is not recognized in the 1st vehicle data storage part 123. FIG. And the character complement part 114 reads the information of 1st vehicle data ID matched with the information of the vehicle number. And the character complement part 114 sends the information of the 1st vehicle data ID to the vehicle number search part 115. FIG.

  When the vehicle number search unit 115 receives the information on the vehicle data ID sent from the character complement unit 114, the vehicle number search unit 115 includes the character complement included in the first vehicle data identified by the information on the first vehicle data ID. The part 114 searches for the second vehicle data including the information of the same vehicle number as the information of the vehicle number supplemented with characters (S313). More specifically, the vehicle number search unit 115 reads out information on the vehicle number associated with the information on the first vehicle data ID received from the character complementing unit 114 from the first vehicle data storage unit 123. . Then, the vehicle number search unit 115 searches the second vehicle data storage unit 124 for information on the vehicle number having the same character string as the character string of the vehicle number indicated by the vehicle number information. As a result, when information on the same vehicle number is searched (S314: Yes), the vehicle number search unit 115 reads out information on the second vehicle data ID associated with the information on the vehicle number. Then, the vehicle number search unit 115 sends the information on the second vehicle data ID and the information on the first vehicle data ID for identifying the first vehicle data to the data association unit 121.

  When the data association unit 121 of the vehicle data processing device 110 receives the information on the first vehicle data ID and the information on the second vehicle data ID sent from the vehicle number search unit 115, the second vehicle data The second vehicle data identified by the ID information is permanently linked to the first vehicle data identified by the first vehicle data ID information. More specifically, the data association unit 121 associates the information of the first vehicle data ID received from the vehicle number search unit 115 with the information of the second vehicle data ID, and the vehicle data storage unit 125. To store. Then, the data association unit 121 deletes the information of the first vehicle data ID and each piece of information associated therewith from the first vehicle data storage unit 123. Further, the data association unit 121 deletes the information of the second vehicle data ID and each piece of information associated therewith from the second vehicle data storage unit 124.

  As described above, the vehicle data processing device 110 supplements a character that has failed optical character recognition in the character string indicated by the vehicle number information of the first vehicle data, and then uses the same vehicle as the vehicle number information. If there is second vehicle data including number information, the second vehicle data is permanently linked to the first vehicle data. This is because it is considered that both data are certainly the data of the same vehicle when the information of the vehicle number matches even after supplementing the character that failed in the optical character recognition.

  On the other hand, when it is determined in the determination as to whether or not the character string of the vehicle number is recognized as a character, all the character strings of the vehicle number are not recognized as characters (S301: No → S311: No ), The optical character recognition availability determination unit 113 sends the information of the first vehicle data ID for identifying the first vehicle data to the overlapping range search unit 116.

  On the other hand, when the information of the same vehicle number is not searched as a result of the search in step S313 (S314: No), the vehicle number search unit 115 identifies the first vehicle data that identifies the first vehicle data. The ID information is sent to the overlapping range search unit 116.

  Upon receiving the information on the first vehicle data ID sent from the optical character recognition availability determination unit 113 or the vehicle number search unit 115, the overlapping range search unit 116 is identified by the information on the first vehicle data ID. Includes roadside wireless device ID information that identifies a roadside wireless device 140 having a communication range C that overlaps the imaging range A of the monitoring camera 130 indicated by the information of the monitoring camera ID included in the first vehicle data. The second vehicle data is searched (S315). More specifically, the overlapping range search unit 116 obtains information on the monitoring camera ID associated with the information on the first vehicle data ID received from the optical character recognition availability determination unit 113 or the vehicle number search unit 115. Read from the first vehicle data storage unit 123. Then, the overlapping range search unit 116 identifies roadside wireless device ID information for identifying the roadside wireless device 140 having the communication range C overlapping the imaging range A of the monitoring camera 130 identified by the information of the monitoring camera ID. The second vehicle data storage unit 124 is searched. As a result, when the information on the corresponding roadside apparatus ID is searched (S316: Yes), the overlapping range search unit 116 obtains the information on the second vehicle data ID associated with the information on the roadside apparatus ID. read out. Then, the vehicle number search unit 115 sends the information on the second vehicle data ID and the information on the first vehicle data ID for identifying the first vehicle data to the enforcement target search unit 117.

  Upon receiving the information on the first vehicle data ID and the information on the second vehicle data ID sent from the overlapping range search unit 116, the control object search unit 117 of the vehicle data processing apparatus 110 receives the second vehicle. The second vehicle data including violation information is searched from the second vehicle data identified by the data ID information (S317). More specifically, the control target search unit 117 stores a value indicating violation content from the violation content information associated with the second vehicle data ID information received from the overlapping range search unit 116. Search for what is being. As a result, when the violation content information storing the value indicating the violation content is not searched (S318: No), the control target search unit 117 receives the first vehicle data ID received from the overlapping range search unit 116. The information and the information of the second vehicle data ID are sent to the vehicle type category search unit 118 and the travel restriction search unit 119.

  Upon receiving the information on the first vehicle data ID and the information on the second vehicle data ID sent from the control target search unit 117, the vehicle type classification search unit 118 uses the information on the second vehicle data ID. Second vehicle data including information on the vehicle type classification different from the information on the vehicle type classification included in the first vehicle data identified by the information of the first vehicle data ID from among the identified second vehicle data. Is searched (S319). More specifically, the vehicle type category search unit 118 obtains vehicle type category information associated with the information of the first vehicle data ID received from the control target search unit 117 from the first vehicle data storage unit 123. read out. The vehicle type category search unit 118 is associated with the information on the second vehicle data ID received from the control target search unit 117, and is different from the vehicle type category information read from the first vehicle data storage unit 123. Search for category information. As a result, when information on the corresponding vehicle type division is searched (S320: Yes), the vehicle type division search unit 118 reads information on the second vehicle data ID associated with the information on the vehicle type division. Then, the vehicle type category search unit 118 sends the information on the second vehicle data ID and the information on the first vehicle data ID for identifying the first vehicle data to the data association unit 123.

  When the travel restriction search unit 119 receives the information on the first vehicle data ID and the information on the second vehicle data ID sent from the control target search unit 117, the travel restriction search unit 119 identifies the information based on the information on the second vehicle data ID. The second vehicle data including the information on the travel restriction (Yes or No) of the value not subject to the travel restriction on the toll road R is searched from the second vehicle data to be performed (S319). More specifically, the travel restriction search unit 119 determines the toll road from the travel restriction (Yes or No) information associated with the information of the second vehicle data ID received from the control target search unit 117. Search for information on values not subject to R travel restrictions. As a result, when the information on the corresponding travel restriction (Yes or No) is searched (S320: Yes), the travel restriction search unit 119 displays the second associated with the information on the travel restriction (Yes or No). Read the vehicle data ID information. Then, the travel restriction search unit 119 sends the information on the second vehicle data ID and the information on the first vehicle data ID for identifying the first vehicle data to the data association unit 121.

  When the data association unit 121 receives the information on the first vehicle data ID and the information on the second vehicle data ID sent from the vehicle type category search unit 118 and the travel restriction search unit 119, the second vehicle data The second vehicle data identified by the ID information is temporarily linked to the first vehicle data identified by the first vehicle data ID information (S304). More specifically, the data association unit 121 associates the information on the first vehicle data ID received from the vehicle type category search unit 118 and the travel restriction search unit 119 with the information on the second vehicle data ID. And stored in the vehicle data storage unit 125. Then, the data association unit 121 deletes the information of the first vehicle data ID and each piece of information associated therewith from the first vehicle data storage unit 123. In this case, the data association unit 121 does not delete the information on the second vehicle data ID and the information associated therewith from the second vehicle data storage unit 124.

  Thus, after complementing the character which failed in optical character recognition among the character strings indicated by the vehicle number information of the first vehicle data, the same vehicle number as the vehicle number information of the first vehicle data is used. When there is no second vehicle data including information, the vehicle data processing device 110 includes information on the vehicle type classification that is different from the information on the vehicle type classification of the first vehicle data, and has a value that is not subject to travel restrictions on the toll road R. The second vehicle data including the travel restriction (Yes or No) information is linked to the first vehicle data. This is because when a vehicle-mounted device other than a regular vehicle-mounted device is attached to the vehicle, a vehicle-mounted device for a vehicle type that has a lower toll than the vehicle type of the vehicle is attached, or traveling on a toll road R This is because there is a high possibility that a vehicle-mounted device that has been set to receive no restrictions is attached.

  On the other hand, if the information of the corresponding roadside wireless device ID is not searched as a result of the search in step S315 (S316: No), the overlapping range search unit 116 identifies the first vehicle data described above. The vehicle data ID information is sent to the data association unit 121.

  When the data association unit 121 receives the information on the first vehicle data ID sent from the overlapping range search unit 116, the data association unit 121 adds the second vehicle to the first vehicle data identified by the information on the first vehicle data ID. The linking of the second vehicle data to the first vehicle data is terminated without linking the data (S304). More specifically, the data association unit 121 stores the information on the first vehicle data ID received from the overlapping range search unit 116 in the vehicle data storage unit 125. Then, the data association unit 121 deletes the information of the first vehicle data ID and each piece of information associated therewith from the first vehicle data storage unit 123.

  As described above, there is no second vehicle data including information on the roadside apparatus ID for identifying the roadside apparatus 140 having the communication range C overlapping the imaging area A in which the target vehicle of the first vehicle data is imaged. In this case, the data association unit terminates the association of the second vehicle data with respect to the first vehicle data on the assumption that the second vehicle data associated with the first vehicle data does not exist. This is because, when the vehicle is imaged by the monitoring camera 130, if the roadside wireless device 140 having the communication range C overlapping the imaging range A of the monitoring camera 130 does not receive data from the vehicle-mounted device, This is because it is considered that data reception from the vehicle-mounted device has failed or the vehicle-mounted device is not attached.

  On the other hand, as a result of the search in step S317, when the violation content information storing the value indicating the violation content is searched (S318: Yes), the enforcement target search unit 117 associates the violation content information with the violation content information. The information on the obtained second vehicle data ID and the information on the first vehicle data ID for identifying the first vehicle data are sent to the data association unit 121.

  When the data association unit 121 receives the information on the first vehicle data ID and the information on the second vehicle data ID sent from the enforcement target search unit 117, the data association unit 121 is identified by the information on the second vehicle data ID. The second vehicle data is provisionally linked to the first vehicle data identified by the information of the first vehicle data ID (S304). More specifically, the data association unit 121 associates the information of the first vehicle data ID received from the enforcement target search unit 117 with the information of the second vehicle data ID, and associates the information with the vehicle data storage unit 125. To store. Then, the data association unit 121 deletes the information of the first vehicle data ID and each piece of information associated therewith from the first vehicle data storage unit 123. In this case, the data association unit 121 does not delete the information on the second vehicle data ID and the information associated therewith from the second vehicle data storage unit 124.

  Thus, after complementing the character which failed in optical character recognition among the character strings indicated by the vehicle number information of the first vehicle data, the same vehicle number as the vehicle number information of the first vehicle data is used. If there is no second vehicle data including information, and there is second vehicle data including information indicating the traffic violation content, the second vehicle data is linked to the first vehicle data. This is because there is no OBE information that matches in the character recognition result, but there is one or more OBE information determined to be illegal near that time, and any OBE information is This is because it is highly likely that the vehicle data matches the vehicle data and that the vehicle is likely to be an unauthorized vehicle.

  On the other hand, as a result of the search in the above step S319, when neither the information of the corresponding vehicle type classification nor the information of the corresponding travel restriction (Yes or No) is searched (S320: No), the vehicle type classification search unit 118 or the travel The restriction search unit 119 sends information on the first vehicle data ID for identifying the first vehicle data to the data association unit 121.

  When the data association unit 121 receives the information of the first vehicle data ID sent from the vehicle type category search unit 118, the data association unit 121 adds the second vehicle to the first vehicle data identified by the information of the first vehicle data ID. The linking of the second vehicle data to the first vehicle data is terminated without linking the data (S304). More specifically, the data association unit 121 stores the information on the first vehicle data ID received from the vehicle type category search unit 118 in the vehicle data storage unit 125. Then, the data association unit 121 deletes the information of the first vehicle data ID and each piece of information associated therewith from the first vehicle data storage unit 123.

  Thus, after complementing the character which failed in optical character recognition among the character strings indicated by the vehicle number information of the first vehicle data, the same vehicle number as the vehicle number information of the first vehicle data is used. When there is no second vehicle data including information and there is no second vehicle data including information on the vehicle type classification different from the information on the vehicle type classification of the first vehicle data, the vehicle data processing device 110 Assuming that there is no second vehicle data associated with the vehicle data, the association of the second vehicle data with respect to the first vehicle data is terminated. This is because the possibility of a normal vehicle is considered high.

  When the data association unit 121 receives the information of the first vehicle data ID sent from the travel restriction search unit 119, the data association unit 121 adds the second vehicle to the first vehicle data identified by the information of the first vehicle data ID. The linking of the second vehicle data to the first vehicle data is terminated without linking the data (S304). More specifically, the data association unit 121 stores the information on the first vehicle data ID received from the travel restriction search unit 119 in the vehicle data storage unit 125. Then, the data association unit 121 deletes the information of the first vehicle data ID and each piece of information associated therewith from the first vehicle data storage unit 123.

  Thus, after complementing the character which failed in optical character recognition among the character strings indicated by the vehicle number information of the first vehicle data, the same vehicle number as the vehicle number information of the first vehicle data is used. If there is no second vehicle data including information, and there is no second vehicle data including travel restriction (Yes or No) information that is not subject to travel restrictions on the toll road R, the vehicle data processing device 110 Assuming that there is no second vehicle data associated with the first vehicle data, the association of the second vehicle data with respect to the first vehicle data is terminated. This is because the possibility of a normal vehicle is considered high.

  In addition, the data linking unit 121 may temporarily link the second vehicle data to the first vehicle data when the second vehicle data is temporarily linked to the other first vehicle data. The temporary association of the second vehicle data with respect to the other first vehicle data is released, and the second vehicle data is permanently associated with the first vehicle data.

  The vehicle data transmission unit 122 of the vehicle data processing apparatus 110 transmits vehicle data including vehicle information included in at least one of the first vehicle data and the second vehicle data to the server 170 (S305). ). More specifically, the vehicle data transmission unit 122, when the data association unit 121 associates the second vehicle data with the first vehicle data, the first vehicle data and the second vehicle data. The vehicle data including the vehicle information included in is transmitted to the server 170. Further, the vehicle data transmission unit 122 associates the second vehicle data with the first vehicle data, assuming that there is no second vehicle data that the data association unit 121 should associate with the first vehicle data. Without completing the association of the second vehicle data with the first vehicle data, the vehicle data including the vehicle information included in the first vehicle data is transmitted to the server 170. In addition, when the data association unit 121 provisionally associates the second vehicle data with the first vehicle data, the vehicle data transmission unit 122 receives the second vehicle after the reception time of the second vehicle data. If the surveillance camera 130 having the imaging range A that overlaps the communication range C of the roadside apparatus 140 that has received the data captures a predetermined number of vehicles, the first vehicle data and the second vehicle data The vehicle data including the vehicle information included and the image indicated by the image ID information included in the first vehicle data is transmitted to the server 170. In addition, when the data association unit 121 temporarily associates the second vehicle data with the first vehicle data, the vehicle data transmission unit 122 has a predetermined time elapsed from the reception time of the second vehicle data. Vehicle data including vehicle information included in the first vehicle data and the second vehicle data and an image indicated by the image ID information included in the first vehicle data is transmitted to the server 170. Send.

  As described above, the monitoring camera 130 images the toll road R over time. The roadside apparatus 140 has a communication range C that overlaps with the imaging range A of the monitoring camera 130. Then, the vehicle data processing device 110 obtains second vehicle data including information on a vehicle that may be the same vehicle as the target vehicle of the first vehicle data from the second vehicle data. Link to vehicle data.

  In this way, depending on the vehicle data processing system 100, in a charging system using GPS, the data capacity of information that leads to the identification of an unauthorized vehicle to be transmitted to a host server or the like can be reduced. It is possible to reduce the load on the network and the burden on the operator who performs artificial processing in the host server. Moreover, in the vehicle data processing system 100, each monitoring camera 130 and each roadside apparatus 140 are connected so that the imaging range A of one monitoring camera 130 and the communication range C of one roadside apparatus 140 overlap. Since the second vehicle data target to be linked to the first vehicle data including the vehicle information captured by the one monitoring camera 130 is set as the roadside radio corresponding to the one monitoring camera 130, for example. The device 140 or the roadside wireless device 140 on both sides of the device 140 may be limited to the information including the vehicle information received from the vehicle-mounted device.

  Further, as described above, the vehicle data processing device 110 includes the second vehicle data including the same vehicle number information as the vehicle number information of the vehicle included in the first vehicle data from the second vehicle data. Search for. Then, the vehicle data processing device 110 permanently links the searched second vehicle data to the first vehicle data.

  In this way, depending on the vehicle data processing system 100, when there is second vehicle data including the same vehicle number information as the vehicle number information of the vehicle included in the first vehicle data, the first vehicle The data can be associated with the second vehicle data.

  Further, as described above, the vehicle data processing device 110 determines whether or not the character string of the vehicle number indicated by the vehicle number information of the vehicle included in the first vehicle data is recognized as a character. When the vehicle data processing device 110 determines that all the character strings of the vehicle numbers indicated by the vehicle number information of the vehicles included in the first vehicle data are recognized as characters, the second vehicle The second vehicle data including the same vehicle number information as the vehicle number information included in the first vehicle data is searched from the data.

  In this way, depending on the vehicle data processing system 100, after confirming that all of the character string of the vehicle number has been recognized by the optical character, the second data for the first vehicle data including the information of the vehicle number is confirmed. Vehicle data can be linked.

  Further, as described above, the vehicle data processing device 110 obtains the second vehicle data including the information on the vehicle type classification different from the information on the vehicle type classification included in the first vehicle data from the second vehicle data. Search for. In addition, the vehicle data processing device 110 searches the second vehicle data for second vehicle data including information on travel restriction (Yes or No) that is not subject to travel restrictions on the toll road R. Then, the vehicle data processing device 110, when the second vehicle data including the same vehicle number information as the vehicle number information included in the first vehicle data is not searched, the vehicle included in the first vehicle data Second vehicle data including information on a vehicle type that is different from the vehicle type information of the vehicle, and second vehicle data including information on a travel restriction (Yes or No) that is not subject to travel restrictions on the toll road R. Temporary tying to the first vehicle data.

  Thus, depending on the vehicle data processing system 100, the first vehicle data including information on a vehicle that may be attached to an on-vehicle device that is not a regular on-vehicle device attached to the vehicle; The second vehicle data can be linked.

  In addition, as described above, the vehicle data processing device 110 has information on the vehicle type that is different from the information on the vehicle type included in the first vehicle data, and the travel restriction (Yes) that is not subject to the travel restriction on the toll road R. or No) information is not retrieved, there is no second vehicle data to be linked to the first vehicle data, so the vehicle is mounted on the vehicle. Assuming that there is no suspicion of fraud, the association of the second vehicle data with the first vehicle data is terminated without associating the second vehicle data with the first vehicle data.

  Thus, depending on the vehicle data processing system 100, when data cannot be received from the vehicle-mounted device, or when the vehicle-mounted device is not attached to the vehicle, the first information including the vehicle information is included. The second vehicle data can be prevented from being associated with the vehicle data.

  Further, as described above, the vehicle data processing device 110 communicates with the imaging range A of the monitoring camera 130 indicated by the information of the monitoring camera ID included in the first vehicle data from the second vehicle data. The second vehicle data including the information on the roadside apparatus ID of the roadside apparatus 140 having the range C is searched. And the vehicle data processing apparatus 110 searches the 2nd vehicle data containing the information of the vehicle type division different from the information of the vehicle type division contained in the 1st vehicle data from the searched 2nd vehicle data, From the searched second vehicle data, second vehicle data including information on a travel restriction (Yes or No) with a value not subject to the travel restriction on the toll road R is retrieved.

  In this way, depending on the vehicle data processing system 100, the roadside of the roadside wireless device 140 having the communication range C overlapping the imaging range A of the monitoring camera 130 indicated by the information of the monitoring camera ID included in the first vehicle data. Only the second vehicle data including the information on the wireless device ID can be a target to be associated with the first vehicle data.

  Further, as described above, the vehicle data processing device 110 includes the roadside wireless device 140 having the communication range C that overlaps the imaging range A of the monitoring camera 130 indicated by the information of the imaging camera ID included in the first vehicle data. If the second vehicle data including the information on the roadside apparatus ID is not searched, it is determined that there is no second vehicle data to be linked to the first vehicle data, and the second vehicle data is second in the first vehicle data. The linking of the second vehicle data to the first vehicle data is terminated without linking the vehicle data.
