Description

Technical Field

[0001] The utility model relates to the technical field of high-speed green pass detection, and in particular to a high-speed smart green pass rapid detection system. Background Art

[0002] In recent years, the application of radiation vehicle detection system on highways is increasingly increasing. By fixing the radiation source on one side of the lane and the radiation detector on the other side, after the vehicle to be inspected enters, the system avoids the cab and turns on the radiation to perform radiation transmission imaging detection on the container or closed vehicle body. Since goods of different densities absorb radiation to different degrees, the intensity of the transmitted radiation signal received by the detector is different. After processing the signals of different strengths, a vehicle scanning image can be generated, and the vehicle can be quickly detected without stopping the vehicle or unpacking it.

[0003] An important condition for transmission imaging detection is that the detection rays emitted by the radiation source can penetrate the inspected vehicle and then irradiate the ray detector on the other side of the lane. The radiation source can be divided into an integrated X-ray device and a split X-ray device. The integrated X-ray device integrates the X-ray tube, high-voltage power supply and cooling device together, which reduces the equipment cost and facilitates maintenance. With the increase in green-pass vehicles, the energy demand of the radiation source is increasing. The current largest energy integrated machine, that is, the 250kv ray device, can meet the detection work of various green-pass vehicles.

[0004] During the use of the ray-based vehicle detection system, when the ray device is turned on, the transmitter cabinet will generate radiation, and there is a certain risk in monitoring the direct radiation leakage dose. If the tester does not take effective radiation protection when approaching the transmitter cabinet, it is easy to cause radiation damage. To this end, those skilled in the art provide a highway smart green pass rapid detection system to solve the problems raised in the above background technology. Utility Model Content
