It constitutes plate extraction means, the vehicle individual identification device 31 constitutes vehicle individual identification means, the radiation measurement device 320 constitutes radiation measurement means, the control device 324 constitutes control means, the vehicle speed detector 370 and the control device 324 constitutes vehicle rear detection means, vehicle speed detector 370 constitutes vehicle speed detection means, control device 324 constitutes measurement time calculation means, radiation dose determination device 34 constitutes radiation dose determination means, and data creation The device 32 constitutes data creation means, the vehicle guidance device 50 constitutes vehicle guidance means, the storage device 44 constitutes storage means, and the input / output device 45 is stored in the storage device 44. It constitutes an output means for outputting the housed data.

  Here, the operation of the above-described automatic dose measurement system 300 for a vehicle will be described.

  First, when the vehicle 301 carrying the ETC on-vehicle device 1 passes, the vehicle information acquisition device 11 acquires the vehicle individual information from the ETC on-vehicle device 1 by wireless communication. At this time, the vehicle front side photographing device 12 starts photographing the vehicle 301 and starts sending the photographed image to the vehicle number extracting device 13. The vehicle speed measuring device 370 measures the speed of the vehicle 301 and transmits the speed of the vehicle 301 to the control device 324. When the vehicle number extraction device 13 recognizes the front side license plate of the vehicle 301 in the captured image, the vehicle number extraction device 13 transmits a measurement start signal of the measurement device main body 221 to the control device 324. Based on this signal, the control device 224 controls the measurement device body 221 to start measuring the radiation dose of the vehicle 301.

  On the other hand, the control device 324 recognizes the vehicle size (vehicle length) corresponding to the vehicle individual information acquired by the vehicle information acquisition device 11 or the vehicle number obtained by the vehicle number extraction device 13. Next, the control device 324 calculates the measurement end time of the measurement device main body 221 from the size (vehicle length) of the vehicle and the vehicle speed obtained by the vehicle speed measuring device 370.

  Subsequently, when the measurement end time has elapsed since the measurement start signal was transmitted, the control device 324 controls the measurement device main body 221 and ends the measurement of the radiation dose of the vehicle 301. Since the measurement area of the radiation dose can be limited to a predetermined area by the shielding plate over a period from the start of measurement of the radiation dose of the vehicle 301 by the measurement apparatus main body 221 to the end of measurement, the vehicle travels before and after the vehicle 301. The influence of the preceding vehicle and the following vehicle can be suppressed to the minimum. The measurement device main body 221 transmits the measurement data to the radiation dose determination device 34. The radiation dose determination device 34 determines whether the radiation dose of the vehicle 301 is equal to or greater than a predetermined value, and transmits the determination result and the radiation measurement data to the data creation device 32.

  Next, the data creation device 32 creates data in which the individual information of the vehicle 301 is associated with the determination result and the radiation dose measurement data, and this data is sent to the data management server 40 and the vehicle via the interface 33 and the network 60. It transmits to the guidance device 50. As a result, the data that associates the individual information of the vehicle 301 with the determination result and the radiation dose measurement data can be stored in the storage device 44 of the data management server 40. Further, the vehicle guidance device 50 guides the vehicle 301 so that the vehicle 301 passes as it is when the radiation dose is low, and travels to a place where the vehicle 301 can be decontaminated when the radiation dose is high. In this way, the vehicle 301 is guided. When the vehicle 301 is guided to a place where decontamination is possible, after the vehicle 301 is washed, the radiation dose of the vehicle 301 is measured again by the radiation measuring device 320, and the radiation measurement data is equal to or greater than the predetermined value. The determination result and the radiation measurement data can be stored in the storage device 44 of the data management server 40 as data associated with the individual information of the vehicle 301.

  Therefore, according to the automatic dose measurement system 300 for a vehicle according to the present embodiment, the radiation dose of the vehicle is automatically identified while identifying the individual vehicle, as in the automatic dose measurement system 200 for the vehicle according to the first embodiment described above. In addition, the vehicle individual information and the radiation dose measurement data of the vehicle can be managed in association with each other. Further, even in the case where a plurality of vehicles pass continuously, the vehicle to be measured 301 and other vehicles (preceding vehicle (not shown) and following vehicle (not shown)) are adjacent in the front and rear vehicles. And only the radiation dose of the measurement target vehicle 301 can be measured. Thereby, the measurement accuracy of the radiation dose of the measurement target vehicle 301 can be increased.

And a radiation measuring device 420.

  As shown in FIGS. 5, 6 (a), and 6 (b), the radiation measuring apparatus 420 includes a rail 429 provided along the road 480 and a plurality of (provided to run on the rail 429). In the illustrated example, four detectors (sensor units) 421a, 421b, 421c, and 421d are provided. The rail 429 is connected to two straight portions 429a and 429b extending in parallel with the lanes 481 and 482 of the road 480, and an arc portion 429c that is connected to an end portion of the straight portion 429a and an end portion of the straight portion 429b to form an arc shape. , 429d.

Thereby, each detector 421a, 421b, 421c, 421d can recognize the vehicle and can run in parallel with the vehicle, and the radiation dose of the vehicle by the measuring device main body 422 of each detector 421a, 421b, 421c, 421d. It is possible to secure a measurement time for measuring.

  The length L1 of the linear portion 429a of the rail 429 and the number of detectors traveling on the rail 429 can be calculated as follows. The time required for the measuring device main body 422 of each detector 421a, 421b, 421c, 421d to measure the radiation dose of the vehicle is 2 seconds, and the speed limit of the vehicle is 20 km / hour (≈5.6 m / second). In this case, the tracking distance (the length L1 of the straight line portion 429a) is 2 seconds × 5.6 m / second≈12 m. When the length of the vehicle is 4 m and the inter-vehicle distance is 2 m or more, the maximum number of vehicles that can run in parallel on the 12 m straight portion 429a is two. In the rail 429, the time required for the measuring instrument to return to the measurement start point after completing the measurement is also required, so the number of detectors traveling on the rail 429 is four.

  The output side of the measuring device main body 422 of each of the detectors 421a, 421b, 421c, and 421d described above is connected to the input side of the radiation dose determination device 34 of the automatic screening device 30. Thereby, the data obtained by measuring the radiation dose of the vehicles 401, 402, and 403 to be measured can be sent to the radiation dose judging device 34.

In addition, the vehicle 401, the vehicle 402, and the vehicle 403 are all equipped with the above-described ETC vehicle-mounted device 1, and the case where the vehicle 401, the vehicle 402, and the vehicle 403 pass continuously will be described.

  First, when a plurality of vehicles pass, the vehicle information acquisition device 11 acquires the vehicle individual information from the ETC on-board device 1 of the first vehicle 401 by wireless communication, and then the base end side of the straight portion 429a (FIG. 6). (B) is close to the right end), and the detector, for example, the detector 421a, which is preparing to measure the radiation dose of the vehicle, enters the region where the vehicle 401 can measure the radiation dose. stand by. When the tracking sensor 425 of the detector 421a detects that the vehicle 401 has started traveling in the radiation dose measurable region, the tracking sensor 425 transmits a signal to the control device 424 of the detector 421a. The control device 424 of 421a controls the traveling device 426 of the detector 421a so as to run in parallel with the vehicle 401, and controls the measuring device main body 422 of the detector 421a so as to measure the radiation dose of the vehicle 401. . When the control device 424 of the detector 421a reaches the measurement end point of the linear portion 429a of the rail 429 (connection portion with the arc portion 429c), the detector 421a ends the measurement of the radiation dose of the vehicle 401. The measurement device main body 422 is controlled. As a result, the radiation dose of the vehicle 401 is measured when the detector 421a is traveling on the straight portion 429a of the rail 429. The measuring device main body 422 of the detector 421a transmits the radiation dose measurement data of the vehicle 401 to the determination device 34 of the automatic screening device 30.

  Subsequently, when the vehicle information acquisition apparatus 11 acquires vehicle individual information from an ETC on-vehicle device (not shown) mounted on the second vehicle 402 subsequent to the first vehicle 401 by wireless communication, the detection is performed. The detector 421b adjacent to the detector 421a waits until the vehicle 402 enters an area where the radiation dose can be measured. When the tracking sensor 425 of the detector 421b detects that the vehicle 402 starts to travel in the radiation dose measurable region, the tracking sensor 425 transmits a signal to the control device 424 of the detector 421b, and The control device 424 of 421b controls the traveling device 426 of the detector 421b so as to run in parallel with the vehicle 402, and controls the measuring device main body 422 of the detector 421b so as to measure the radiation dose of the vehicle 402. . When the control device 424 of the detector 421b reaches the measurement end point of the linear portion 429a of the rail 429 (connection portion with the arc portion 429c), the detector 421b is configured to end the measurement of the radiation dose of the vehicle 402. The measurement device main body 422 is controlled. Thereby, the radiation dose of the vehicle 402 is measured when the detector 421b is traveling on the straight portion 429a of the rail 429. The measuring device main body 422 of the detector 421b transmits the radiation dose measurement data of the vehicle 402 to the determination device 34 of the automatic screening device 30.

  Subsequently, when the vehicle information acquisition device 11 acquires vehicle individual information from an ETC on-board device (not shown) mounted on the third vehicle 403 following the second vehicle 402 by wireless communication, the detection is performed. The detector 421c adjacent to the detector 421b waits until the vehicle 403 enters an area where the radiation dose can be measured. When the tracking sensor 425 of the detector 421c detects that the vehicle 403 starts to travel in the radiation dose measurable region, the tracking sensor 425 transmits a signal to the control device 424 of the detector 421c, The control device 424 of 421c controls the traveling device 426 of the detector 421c so as to run in parallel with the vehicle 403, and controls the measuring device main body 422 of the detector 421c so as to measure the radiation dose of the vehicle 403. . When the control device 424 of the detector 421c reaches the measurement end point of the linear portion 429a of the rail 429 (connection portion with the arc portion 429c), the detector 421c stops the measurement of the radiation dose of the vehicle 403. The measurement device main body 422 is controlled. As a result, the radiation dose of the vehicle 403 is measured when the detector 421c is traveling on the linear portion 429a of the rail 429. The measuring device main body 422 of the detector 421c transmits the radiation dose measurement data of the vehicle 403 to the determination device 34 of the automatic screening device 30.

When the tracking sensor 425 of the detector 421d detects that the vehicle has started traveling in the radiation dose measurable region, the tracking sensor 425 transmits a signal to the control device 424 of the detector 421d, and the detector 421d. The control device 424 controls the traveling device 426 of the detector 421d so as to run in parallel with the vehicle, and controls the measuring device main body 422 of the detector 421d so as to measure the radiation dose of the vehicle. When the control device 424 of the detector 421d reaches the measurement end point (connection point with the arc portion 429c) of the linear portion 429a of the rail 429, the detector 421d ends the measurement of the radiation dose of the vehicle. The measurement device main body 422 is controlled. Thereby, when the detector 421d is traveling on the straight portion 429a of the rail 429, the radiation dose of the vehicle is measured. The measuring device main body 422 of the detector 421d transmits the measurement data of the radiation dose of the vehicle to the determination device 34 of the automatic screening device 30.

  When the detectors 421a, 421b, 421c, and 421d reach the measurement end point of the linear portion 429a of the rail 429, the detectors 421a, 421b, 421c, and 421d travel to the circular arc portion 429d through the circular arc portion 429c and the linear portion 429b. I will wait at.

Further, when the radiation dose is low, the vehicle guidance device 50 guides the vehicles 401, 402, 403, and the vehicle so that the vehicles 401, 402, 403 and the vehicle pass as they are, and the radiation dose is high. The vehicle 401, 402, 403 and the vehicle are guided so as to travel to a place where the vehicle 401, 402, 403 and the vehicle can be decontaminated. When the vehicles 401, 402, 403 are guided to a decontaminated place, the vehicles 401, 402, 403 and the vehicles are washed, and then the radiation measuring device 220 again performs the vehicles 401, 402, 403 and the vehicles. The radiation dose is measured, it is determined whether the radiation measurement data is equal to or greater than the predetermined value, and the determination result and the radiation measurement data are associated with the vehicles 401, 402, 403 and the individual information of the vehicle as data.

Further, the vehicle guidance device 50 guides the vehicle 501 so that the vehicle 501 passes as it is when the radiation dose is low, and travels to a place where the vehicle 501 can be decontaminated when the radiation dose is high. In this way, the vehicle 501 is guided. When the vehicle 501 is guided to a place where decontamination is possible, after the vehicle 501 is cleaned, the radiation dose of the vehicle 501 is measured again by the radiation measuring device 520, and the radiation measurement data is equal to or greater than the predetermined value. The determination result and the radiation measurement data can be stored in the storage device 44 of the data management server 40 as data associated with the individual information of the vehicle 501.

  Therefore, according to the automatic dose measurement system 500 for a vehicle according to the present embodiment, the radiation dose of the vehicle can be automatically measured while identifying the individual vehicle, and the individual information of the vehicle and the radiation dose of the vehicle can be measured. It can be managed in association with measurement data. Further, a plurality of upper measuring instruments 522a1, 522a2, 522a3, 522a4, a plurality of right measuring instruments 522b1, 522b2, 522b3, 522b4, and a plurality of left measuring instruments 522c1, 522c2, 522c3, 522c4 are arranged above the measurement target vehicle 501. Based on the data obtained by measuring the radiation dose on the right and left sides, the radiation dose distribution of each part can be obtained. Thereby, when it is necessary to decontaminate the vehicle, decontamination work can be efficiently performed because decontamination can be performed based on the radiation dose distribution of each part.

  It is also possible to combine the above-described automatic dose measurement system for vehicles according to the first and second embodiments with the automatic dose measurement system for vehicles according to the above-described fourth embodiment.

  The vehicle automatic dose measurement system according to the present invention can automatically measure the radiation dose of the vehicle while identifying the individual vehicle, and associates the individual vehicle information with the measurement data of the radiation dose of the vehicle. Since it can be managed, it can be used extremely beneficially in industry.
