The vehicle (mobile body 20) in the present embodiment is equipped with an in-vehicle device 50 having a positioning function using GPS. An IC card 50a in which a monetary amount or a value corresponding thereto is written is inserted into the in-vehicle device 50. When the mobile charging system 100 is activated, the in-vehicle device 50 reads and executes the charging processing program 57 stored in advance in the storage unit 55 by the CPU 53. When the program is executed, the vehicle-mounted device 50 subtracts the charge amount from the IC card 50a when it is determined that the vehicle on which it is loaded has reached the charge zone 60 stored in the vehicle-mounted device 50 in advance. leave. The charge amount is stored in advance as a charge table in the vehicle-mounted device 50, or is calculated by the vehicle-mounted device 50 at that time. As shown in the data flow 200 of the mobile charging system shown in FIG. 8, the charging result is transmitted from the vehicle-mounted device 50 to the center system 30 wirelessly using the mobile communication function managed by the communication carrier 220. Is done. At the same time, position information for identifying the charging zone for which the charging process has been performed is also transmitted to the center system 30.

  In the center system 30, an authentication computer belonging to the center system 30 authenticates the mobile object 20 as follows. When the mobile charging system 100 is activated, the CPU 33 reads and executes the mobile charging program 37 stored in the storage unit 36 in advance. When the program is executed, as shown in the processing flow of the center system in FIG. 9A, the information included in the received transaction is based on the reception of the transaction including the accounting result from the in-vehicle device 50 (step S200). A transaction reception process for classifying (step S210). And the vehicle which has loaded the said onboard equipment 50 by collating the vehicle identification information sent from the onboard equipment 50 and the unauthorized vehicle DB which stored in advance and stored the vehicle identification information of the unauthorized vehicle. DB search processing for checking whether or not the vehicle is an unauthorized vehicle is executed (step S220). Next, a transaction evaluation process is performed for determining whether or not charging is normally performed for the usage details and the electronic signature transmitted from the vehicle-mounted device 50 based on the user registration registered by the driver 230 (step S230). ). The usage details and electronic signature processed in the center system 30 are transmitted to the card issuer 210. When payment is approved by the card issuer 210, the amount is deducted from the driver account 242 opened by the driver 230 in the bank 240 or the like, and the card issuer 210 passes the center system 30 via the card issuer account 241. On the other hand, an amount corresponding to the toll for use in the charging zone 60 is remittance. When a series of processes are completed in the center system 30, a DB registration process is performed in which the transaction sent from the vehicle-mounted device 50 and the evaluation result performed in the center system 30 are stored in the transaction DB (step S240). Furthermore, the vehicle identification information is read from the transaction transmitted from the vehicle-mounted device 50, the license plate information corresponding to the vehicle is retrieved based on the data, and the retrieved license plate information is transmitted to the local controller 40. Controller transmission processing is performed (step S250). At this time, along with the license plate information, an “image deletion request” that is data indicating “image discard is possible” or an “image transmission request” that is data indicating “image transmission required” is also added.

  In the above-described DB search process (step S220) and transaction evaluation process (step S230), if it is determined that the billing has been processed normally (that is, the authentication has been successful), the image is discarded and an unauthorized vehicle Alternatively, if it is determined that charging has failed (that is, authentication has failed), “image transmission required” is set. Other than the billing result, for example, a list of the in-vehicle device 50 and the IC card 50a is searched, and in the case of the theft or unregistered in-vehicle device or IC card, if “image capture required” is specified, images of those vehicles are captured. It can be transmitted to the center system 30. Information necessary for billing calculation and vehicle identification information such as billing point data and billing table stored in the vehicle-mounted device 50 can be updated by the mobile communication means from the input unit 35 of the center system 30.

When the license plate is successfully cut out (step S430), and it is confirmed that the cut out license plate is the first one for the target vehicle, the license plate of the cut out license plate is subsequently obtained. A reading process is performed (step S440). In the license plate reading process, the license plate characters are successfully recognized (step S450), and the image whose number is confirmed to be the first for the target vehicle is compressed into JPEG or the like. After (Step S470), it is stored in the drawing process result DB. On the other hand, when the license plate is successfully cut out (step S430) and it is confirmed that the cut out license plate is not the first for the target vehicle, or in the license plate reading process, When the character recognition is successful (step S450) and it is confirmed that the license plate number is not the first for the target vehicle (step S460), the image is discarded (step S480). .

  In the local controller 40, when the mobile charging system 100 is activated, the CPU 43 reads and executes the captured image processing program 47 stored in advance in the storage unit 45. When the program is executed, as shown in FIG. 10B, reception processing for responding to various requests transmitted from the center system 30 is performed (step S500). When receiving an image request (step S510) or an image deletion request (step S540) transmitted from the center system 30, the local controller 40 refers to the image processing result DB and generates a necessary message.

  When an image deletion request (step S540) is transmitted from the center system 30, the license plate information corresponding to the license plate information sent at the same time and the image stored in the image processing result DB correspond to the license plate information. The image is searched and extracted, and the extracted image is deleted from the image DB (step S550). Then, an image deletion message that reports that the image has been deleted is created (step S560), and the message is transmitted to the center system 30 (step S570). When the license plate information is not attached from the center system 30, the photographed image, the license plate recognition result recognized from the image, the photographed location information, and the time are transmitted to the center system 30, respectively.

The local system 39 is installed at all the outlets 60out of the charging zone 60, that is, at all places where the mobile unit 20 can leave the charging zone 60. The local system 39 includes a camera 79 that includes an exit 60out, which is a place where the mobile unit 20 exits from the charging zone 60, and a communication unit 81 that transmits an image captured by the camera 79 to the center system 30. Prepare.

  The moving body 20 enters the charging zone 60. The vehicle-mounted device 50 generates position information indicating its own position based on the GPS information 15 received from the GPS satellite 10. The vehicle-mounted device 50 collates the geographical positional relationship between its own position and the charging zone based on the charging zone information (see FIG. 7) that is geographical information indicating the charging zone 60 and the position information. The mobile unit 20 recognizes that it has entered the charging zone 60.

  When the vehicle-mounted device 50 recognizes that the moving body 20 traveling in the charging zone 60 reaches the boundary between the charging zone 60 and the outside and is located at the outlet 60out of the charging zone 60, the vehicle-mounted device ID and the vehicle-mounted device The transaction information including the card ID which is the identifier of the card inserted in 50 and the position information is transmitted to the center system 30 by the mobile communication technique. The center system 30 stores the received transaction information in association with the transaction information reception time that is the time of reception (see (2) # 1 in FIG. 5).

  The local system 39 generates an all-moving body photographed image obtained by photographing all the moving bodies 20 exiting from the exit 60out of the charging zone 60 at the place where the camera 79 is installed. The all-moving body photographed image is, for example, a moving image photographed continuously with the outlet 60out in the field of view. The communication unit 81 obtains local system information including the all-moving body captured image, the imaging time, and the local system ID (for example, latitude and longitude information) for specifying the position of the local system 39 as the center system 30. Send continuously in real time. The center system 30 stores the received local system information (see (5) # 2 in FIG. 5).

At that time, in order to execute the check accurately, it is required that a camera side system such as the local controller 40 provided in a large number of billing zones uses accurate time information.

  Referring to FIG. 16, the mobile charging system in the present embodiment includes a GPS receiver 30a connected to center system 30a in addition to the configurations shown in the first to seventh embodiments. The center system 30a receives GPS information transmitted from a GPS satellite via the GPS receiver 30a, and acquires GPS time, which is information indicating an accurate time at the time of reception, from the GPS information.

  The center system 30a distributes the GPS time to all the local systems installed in the charging zone 60, that is, the local controller 40, the license plate image acquisition device 80, and the like. In the local side system, image information with time is generated by adding the time adjusted by the received GPS time to the image obtained by capturing the moving body 20. Based on the image information with time, the local side system converts the image of the moving body 20, the information of the license plate read from the image, or the information obtained by converting the information of the license plate into the corresponding vehicle ID. To the center system 30.

  The vehicle-mounted device 50 acquires the GPS time using the GPS function, and transmits it to the center system 30 together with the position information. Since both the information received by the center system 30 from the vehicle-mounted device 50 and the information received from the local system are synchronized with each other according to the GPS time, it is possible to accurately execute charging authentication. According to such a mobile charging system, a large-scale synchronization system can be easily constructed.

(Embodiment 9) Mobile charging system in which local side acquires time by GPS function and synchronizes with reference to FIG. 17, GPS receiver installed in center system 30 in mobile charging system in Embodiment 8 Instead of 30a, GPS receivers 78-1 to 78-N are installed in each of the local systems (cameras 79-1 to 79-N) installed in a large number in the charging zone 60. The local system generates position information and GPS time based on the GPS signals received from the GPS satellites 10 by the GPS receivers 78-1 to 78 -N, and adds them to information obtained by photographing the moving body. To the center system 30.

  According to such a mobile charging system, a large-scale synchronization system can be easily constructed as in the eighth embodiment. Further, since the local system can acquire position information by the GPS function, it is not necessary to separately input and manage the position of the local system in the database.
