The X-ray machine and the imager are connected to the upper computer software control system in communication, respectively, and can perform X-ray digital imaging and transillumination detection on the vehicle's cargo situation.

[0018] The X-ray emitter and the imager are respectively arranged on both sides of the exit lane, the 3D laser radar is communicatively connected with the X-ray emitter, and the imager is communicatively connected with the host computer software control system.

[0019] The 3D laser radar calculates the vehicle's speed, the position of the vehicle's front and the X-ray machine, which helps avoid the vehicle's front and protect the driver from X-rays, thereby improving safety.

[0020] The X-ray machine and imager are installed in separate housings, which are protected by lead. There are three color alarm lights on the top of the X-ray machine housing to warn of the working status of the X-ray machine; there is a protective shutter at the front of the imager to protect the imager.

[0021] The housing where the X-ray emitter and the imager are located also includes a cooling and constant temperature system.

[0022] The X-ray image of the cargo in the carriage is displayed through the imaging device acquisition and software processing system, and the cargo in the X-ray image is judged and identified.

[0023] The three-in-one license plate vehicle side recognition device is located on the island on the right side of the driving direction. It is small and independent and does not need to be fixed by tooling such as railings.

[0024] It also includes a roof camera installed under the rainproof roof of the toll booth to collect roof image information.

[0025] After the green-pass vehicle triggers the reservation button, the No. 1 barrier machine drops, and the LED screen displays: The reservation is successful, please drive forward slowly. The vehicle enters area 1; the radar determines that there is no car in area 2, and the barrier machine lifts the barrier after 2 seconds, and the vehicle enters area 2. If there is a car in area 2, the radar tracks it in real time. After there is no car in area 2, the radar sends a command to the software to lift the barrier machine No. 1, and the green-pass vehicle enters area 2; when the green-pass vehicle enters area 2 from area 1, the radar detects the vehicle speed and vehicle position information in real time, and sends a command to open the light gate after the front of the vehicle passes the optical machine; when the green-pass vehicle enters area 2, after the rear of the vehicle passes the barrier machine, the No. 1 barrier drops, and the LED screen displays: The green-pass vehicle is being detected, please wait for the rear vehicle, and the radar assists the optical machine to close the light gate after the rear of the vehicle passes the optical machine; after the detection, the radar determines that there is no car in area 2, the reservation button is not triggered, and the No. 1 barrier is lifted for ordinary vehicles to pass. If the reservation button is triggered, continue to detect according to the normal process.

[0026] The green channel vehicle quick inspection system provided by the present application can perform radiation inspection on the cargo condition of the vehicle to prevent the green channel from being maliciously used, and can avoid the cab to minimize the damage caused by the X-ray machine to the driver's body.

[0027] The control program can automatically and clearly and accurately collect the image information, speed and license plate number of the vehicle. The image program can display and save the image of the X-rayed compartment, which is identifiable and traceable. The image is used as the basis for judging whether the green pass vehicle is free, and the one-to-one correspondence between vehicle information, driver information and compartment detection information is achieved, which is convenient for the management of high-speed traffic.
