Furthermore, the roadside device 300 may be of a mobile type instead of a fixed type. In this case, the WCN data, image data, detection time, and detection position information may be transmitted to the management server 100 as vehicle identification information.

(3. Regarding acquisition of WCN data and vehicle number)
Acquisition of WCN data and vehicle number will be explained using FIG. 3. FIG. 3A shows a block diagram of the in-vehicle device 200 installed in each vehicle. The in-vehicle device 200 is an ETC (Electronic Toll Collection System) in-vehicle device and has a DSRC communication function. The in-vehicle device 200 includes a control section 202, a wireless communication section 203, a card reading section 204, and a storage section 206.

The control unit 202 has a CPU and a memory, and controls each part of the in-vehicle device 200. The wireless communication unit 203 is a communication unit that enables wireless communication by DSRC, and has an antenna 203a for wireless communication. The control unit 202 stores WCN data that is identification information of the own device. The card reading unit 204 is an ETC card reading device, and when an ETC card is inserted, it can read the card information stored in the card.

FIG. 3B shows a block diagram of the roadside device 300. The roadside device 300 has a DSRC communication function, a wired communication function, and an imaging function. The roadside device 300 includes a control section 301, a wireless communication section 302, a wired communication section 303, a storage section 304, and an imaging section 305.

The control unit 301 includes a CPU, a memory, and the like, and controls each unit of the roadside device 300.

The wireless communication unit 302 is a communication unit that enables wireless communication using DSRC with a vehicle that has entered the wireless communication area 220 (see FIG. 1), and has an antenna 302a for wireless communication. The wired communication unit 303 communicates with the connected management server 100 via the communication network.

Note that communication with the management server 100 may be wireless communication instead of wired communication. In the case of wireless communication, communication may be performed using a different frequency or wireless communication method from that of the wireless communication unit 302.

Therefore, in this embodiment, the communication line includes both wired communication lines and wireless communication lines.

The imaging unit 305 includes a camera (not shown) and captures a moving image of a vehicle that has entered the wireless communication area 220 shown in FIG. The control unit 301 analyzes the video data and acquires the vehicle number if it exists. Further, the imaged vehicle transmits the set data with the WCN data received at the time when it entered the wireless communication area 220 to the management server 100 via the wired communication unit 303 .

The storage unit 304 stores information such as video data received from the in-vehicle device 200.

In this embodiment, video data is analyzed, but continuous still images may be captured and the vehicle number may be extracted from the still images.

(4. Hardware configuration)
The hardware configuration of the management server 100 shown in FIG. 2 will be explained using FIG. 4. The figure shows an example of a hardware configuration in which the management server 100 is configured using a CPU.

The management server 100 includes a CPU 23, a memory 27, a heart disk 26, a monitor 30, a communication board 31, an input device 28, an optical drive 25, and a bus line 29. The CPU 23 controls each section via the bus line 29 according to each program stored on the hard disk 26.

The hard disk 26 stores an operating system program 26o (hereinafter abbreviated as OS) and a main program 26p. The hard disk 26 includes a jurisdiction-specific vehicle database 26t, a wide area vehicle database 26a, a detection information database 26s, a detection base information database 26g, and a storage section 26k.

The processing of the main program 26p will be described later.

FIG. 5 shows the data structure of detection information data stored in the detection information database 26s. In this embodiment, the detection information data includes the items "detection ID", "WCN data", "detection time", "detection base ID", "antenna No.", "antenna direction", "vehicle number" (Land Transport Bureau , vehicle type, kana, car number), and "arranged vehicle ID."

"Detection ID" is a unique identifier assigned in the order of detection. For each detection ID, the items "detection time", "detection base ID", "antenna No.", and "antenna direction" are stored together with the vehicle identification information received from each roadside device 300.

The item “detection base ID” is a unique ID for each roadside device 300. The reason why one "detection base ID" has multiple "antenna numbers" is because it may have multiple antennas. At that time, the "antenna direction" is also stored.

FIG. 7 shows the data structure of the arranged vehicle data stored in the jurisdiction-based arranged vehicle database 26t. Arranged vehicle data consists of the items "arranged vehicle ID", "WCN data", "vehicle identification name", "vehicle classification", and "vehicle number (Land Transport Bureau, vehicle type, kana, car number)" . The item "vehicle identification name" is a memo field in which users can write freely, and is used by humans to identify the characteristics of the vehicle being ordered, the name of the incident, etc. The item "vehicle classification" is a data item that specifies whether the vehicle is a wide area arrangement, a local arrangement, or a stolen vehicle. Generation of vehicle data arranged by jurisdiction will be described later.

FIG. 8 shows the data structure of the arranged vehicle data stored in the wide area arranged vehicle database 26a. In this embodiment, the wide-area arranged vehicle data is composed of the items "arranged vehicle ID", "arranging source jurisdiction", and "WCN data".

FIG. 9 shows the data structure of the detection base information data stored in the detection base information database 26g. The detection base information data is composed of the items "detection base ID" and "location information".

In this embodiment, LINUX (registered trademark or trademark) is used as the operating system program (OS) 26o, but the present invention is not limited to this.

Note that each of the above programs is read out from the CD-ROM 25a in which the programs are stored via the optical drive 25 and installed on the hard disk 26. In addition to the CD-ROM, a program may be installed on the hard disk from a computer-readable recording medium such as a flexible disk (FD) or an IC card. Furthermore, it may be downloaded using a communication line.

In this embodiment, by installing the program from the CD-ROM onto the hard disk 26, the program stored on the CD-ROM is indirectly caused to be executed by the computer. However, the present invention is not limited to this, and the program stored in the CD-ROM may be directly executed from the optical drive 25. Programs that can be executed by a computer include those that can be executed directly by simply installing them, as well as those that need to be converted to another format (for example, programs that have been compressed and need to be decompressed). ), and also those that can be executed in combination with other module parts.

The hardware configuration of the receiving terminal 400 shown in FIG. 1 is the same as that of a normal notebook computer equipped with a browser application, so a description thereof will be omitted.

(5. Detection information storage processing)
The detection information acquisition process shown in FIG. 5 will be described using FIG. 10A.

The control unit 301 shown in FIG. 3B determines whether a vehicle is detected in the imaging data provided from the imaging unit 305 (step S1 in FIG. 10A). When a vehicle is detected in the imaged data, the vehicle number is analyzed (step S3). Any process may be used to analyze the vehicle number from the image data, and any known means may be employed.

The control unit 301 determines whether to detect WCN data (step S5 in FIG. 10A). In this embodiment, WCN data detection is determined as follows. The time at which the vehicle was detected is identified in the image data captured by the image capturing unit 305. Among the WCN data from a vehicle that has entered the wireless communication area 220 shown in FIG. 1, if there is WCN data received between the specified time and the time range that can be determined to be the vehicle, it is determined that WCN data has been detected. However, it is not limited to this.

Alternatively, a GPS device may be installed in the vehicle to transmit position information together with WCN data to the roadside device 300, and a combination with matching position information may be selected.

In this embodiment, a roadside device having one wireless communication unit is used to detect multiple vehicles at the same time, but a roadside device having multiple wireless communication units may be used.

The control unit 301 creates detection information data (step S7 in FIG. 10A). As explained above, the detection information data includes the items "WCN data", "detection time", "detection base ID", "antenna number", "antenna direction", "vehicle number" (land transport station, vehicle type, etc.) , car number), and "arranged vehicle ID". Data on the detection time, detection base ID, antenna N, and antenna direction may be added to the WCN data detected in steps S3 and S5.

The control unit 301 transmits the generated detection information data to the management server 100 (step S9 in FIG. 10A).

When the management server 100 receives such detection information data, it assigns a detection ID and adds the new detection information data to the detection information database shown in FIG. 5.

Thereby, combination data of the vehicle number detected by the roadside device 300 and WCN data can be acquired.

(6. Arranged vehicle registration process)
The arranged vehicle registration process shown in FIGS. 7 and 8 will be explained using FIG. 10B. The CPU 23 of the management server 100 receives a request for registration of an arrangement target from the receiving terminal 400. This registration request includes various data such as "vehicle identification name", "vehicle classification", and "vehicle number (Land Transport Bureau, vehicle type, kana, car number)".

The CPU 23 determines whether the vehicle number requested for registration exists in the jurisdiction-specific vehicle combination database (step S11). If the requested vehicle number does not exist in the jurisdiction-specific vehicle combination database, it is registered in the jurisdiction-specific vehicle combination database without WCN data (step S13). For example, if the jurisdiction-based arranged vehicle combination database is shown in FIG. 6A, the registration request includes arranged vehicle ID "140001", vehicle identification name "arranged vehicle B", vehicle classification "arranged vehicle", Land Transport Bureau "Okayama", and vehicle type. When "330", Kana "U", and car number "4698" are given, the database of vehicle combinations arranged by jurisdiction will be as shown in FIG. 6B.

On the other hand, if the requested vehicle number exists in the jurisdiction-specific vehicle combination database, WCN data is added and registered in the jurisdiction-specific vehicle combination database (step S15 in FIG. 10B). For example, if the jurisdiction-based arranged vehicle combination database is shown in FIG. 6A, the registration request includes arranged vehicle ID "140001", vehicle identification name "arranged vehicle B", vehicle classification "arranged vehicle", Land Transport Bureau "Okayama", and vehicle type. If "330", "Kana", and car number "4698" are given, and the WCN data corresponding to the vehicle number is "987654321098", the database of vehicle combinations arranged by jurisdiction will be as shown in FIG. 6C.

In the present embodiment, the case has been described in which the item "arranged vehicle ID" is included in the registration request, but the item "arranged vehicle ID" may be uniquely assigned by the management server 100.

The CPU 23 determines whether the given registration request includes a wide area arrangement instruction (step S17 in FIG. 10B). If the given registration request includes a wide area arrangement instruction, specifically, if the vehicle classification is "wide area arrangement vehicle", the CPU 23 stores it in the wide area arrangement vehicle database (step S29).

Step S29 is a process of adding the wide area arrangement vehicle combination data shown in FIG. 8 to the wide area arrangement vehicle combination database.

In this embodiment, the wide-area arrangement vehicle combination data is managed as a separate database from the jurisdiction-specific arrangement vehicle combination data. The significance of this will be discussed later.

Note that if the given registration request does not include a wide area arrangement instruction, the CPU 23 does not perform the process of step S29 and ends the process.

(7. Arranged vehicle detection process)
Arranged vehicle detection processing in the roadside device 300 and the management server 100 will be described using FIG. 11.

As already explained, in the detection information storage process, the roadside device 300 acquires the WCN data and the vehicle number, and transmits the detection information data to the server (Step S9 in FIG. 10A).

The CPU 23 of the management server 100 determines whether or not to receive such detection information data (step S31 in FIG. 11), and upon receiving the detection information data, determines whether there is matching WCN data in the jurisdiction-specific arrangement vehicle combination database. (Step S33). If there is matching WCN data, it is determined whether the vehicle numbers match (step S35).

If the WCN data and vehicle number match, the vehicle is determined as the arranged vehicle (step S37). On the other hand, if there is WCN data but the vehicle numbers do not match, the vehicle is determined to be a vehicle with a false number (step S45). This is a case where the combination of both has changed from the previous detection, and one of the reasons may be that the thieves have changed the numbers. Note that since the combination may be changed due to being sold as a used car, it may be treated as a possibility that the license plate number is forged.

The CPU 23 determines whether the vehicle is a widely arranged vehicle (step S39). This can be determined by determining whether the vehicle classification by jurisdiction is "wide area vehicle", which matches in step S35. If the vehicle is a widely-arranged vehicle, the detection information is sent to the receiving terminal of the police that made the wide-area arrangement. As detection information, the detection point information is read out using the detection point ID of the detection information data shown in FIG. 5 as a key, and this is combined with the detection information data shown in FIG. ”, “Detection position information”, “Antenna No.”, “Antenna direction”, “Vehicle number” (Land Transport Bureau, Vehicle type, Kana, Car number), and “Arranged vehicle ID” may be transmitted as the detection information.

Thereby, the detection information regarding the arranged vehicle can be reported to the receiving terminal of the police having jurisdiction over the area that has made the wide-area arrangement.

In step S39, if the vehicle is not a widely ordered vehicle, the detection information regarding the wanted vehicle is notified to the receiving terminal of the police having jurisdiction.

The reason for this distinction between regionally arranged vehicles and jurisdictionally arranged vehicles is as follows. This is because, depending on the case, arrangements may need to be made across prefectures.

In addition, in step S33, if there is no matching WCN data in the jurisdiction-by-jurisdiction vehicle combination database, it is determined whether there is matching WCN data in the wide area arrangement vehicle combination database (step S47). If there is matching WCN data, the process from step S35 onwards is performed, and if there is no matching WCN data, the process ends.

In this way, in this embodiment, the correspondence data between WCN data and vehicle number is stored in advance in the roadside device 300 as detection information data, and when the vehicle number of the arranged vehicle is given, this detection information data is used. Then, it is converted to WCN data of the arranged vehicle and stored as arranged vehicle data. When the roadside device 300 acquires WCN data in this state, it uses this data as a key to determine whether the vehicle in question is an arranged vehicle. Therefore, even if the correspondence data between the WCN data and the vehicle number is unknown, detection using the WCN data of the arranged vehicle is possible.

In addition, since wide-area vehicle combination data is stored, it is possible to detect vehicles arranged by police outside the jurisdiction, and to notify police in different jurisdictions.

In this embodiment, if the vehicle numbers do not match in step S35 of FIG. 11, it is determined that the vehicle number is a counterfeit number, and detection information is provided in step S41 or step S43. This has the following advantages.

WCN data cannot be visualized by humans, but vehicle numbers can. In the case of a fake license plate, even if the vehicle in question can be detected using WCN data alone, it is not possible to determine which vehicle is the relevant vehicle. On the other hand, since it is a counterfeit license plate and the vehicle number currently assigned to the license plate can be identified, it is possible to determine whether the vehicle is stolen.

In this embodiment, a case has been described in which wide-area arrangements are made in addition to within-jurisdictional arrangements, but wide-area arrangement processing is optional.

(8. Other embodiments)
Using the detection information database shown in FIG. 5, the movement history of the arranged vehicle can be displayed. For example, you can do as follows. A user of the management server 100 inputs WCN data for which movement history is desired to be displayed. The CPU 23 (see FIG. 4) of the management server 100 receives this input and extracts the detection information data having the WCN data. The CPU 23 rearranges the extracted detection information data in chronological order based on the detection time. Using the detection base information shown in FIG. 9, the CPU 23 reads the position information, places the points on the map as passing points, and displays routes connecting the passing points in the order of arrangement on the monitor 30 (see FIG. 4).

Note that route display is optional. It is also optional to arrange them in chronological order. Furthermore, when extracting detection information data having specified WCN data, a period for extraction may be specified, and detection information data within the specified period may be detected.

Further, in this example, a case has been described in which the user of the management server 100 inputs WCN data, but the vehicle number may be specified and the detection information data may be extracted using this as a search key.

In the embodiment described above, the fixed roadside device 300 detects combination data of WCN data and image data for generating existing extraction combination data, and also performs an arranged vehicle detection process. However, the present invention is not limited to this, and may be configured by a movable roadside device. In that case, the detected location information (latitude and longitude, etc.) may be given to the management server 100 from the roadside device.

Furthermore, in the wanted vehicle detection process, since the vehicle number imaging process is not essential, a WCN data acquisition device may be installed in the police vehicle and only the wanted vehicle detection process may be performed. At this time, the arranged vehicle combination data stored in the management server 100 may be transmitted to the police vehicle and stored therein.

Furthermore, the roadside device 300 can be installed only for detecting the arranged vehicle. In this case, an imaging means is not necessary, and only a WCN data acquisition device may be installed. In this case, the roadside device 300 may be fixed or a semi-fixed type that is portable. At this time, the determination of the vehicle to be arranged may be made by the management server 100 or may be made by the WCN data acquisition device.

In the embodiment described above, the wide-area vehicle combination data is recorded in each police system, but it may be possible to have one database for the whole country.

Further, some functions of the management server 100 may be provided within the roadside device 300. For example, the existing extraction combination data generation means 3 of FIG. .

Further, the arranged vehicle combination data storage means 6 and the arranged vehicle detection means 7 may be provided in the roadside device 300, and the detection results of the roadside device 300 may be transmitted to the management server 100 and provided to the communication means 8. Furthermore, the communication means 8 may be provided in the roadside device 300.

Further, it is also possible to mount a measuring device including a control section 301, an imaging section 305, and a wireless communication section 302 shown in FIG. In this case, as long as the vehicle to be detected is in a state where WCN data can be exchanged, detection is possible even if the vehicle is not moving (for example, stopped).

In the embodiment described above, in order to realize the functions shown in FIG. 1, the CPU 23 is used and this is realized by software. However, part or all of it may be realized by hardware such as a logic circuit. Note that part of the processing of the program may be performed by an operating system (OS).
