Mobile in-vehicle panoramic X ray backscatter scanning safety check device

Abstract

The invention relates to a mobile in-vehicle panoramic X ray backscatter scanning safety check device. The device includes a flying-spot scanning module, an electric control robotic arm, a numerical control case and a remote terminal. The electric control robotic arm is used for inserting the flying-spot scanning module into the inner part of the car and adjusting the space attitude and controlling angle and scope of the flying-spot scanning module; and the flying-spot scanning module is used for generating an one-dimensional thin beam used for performing scanning in the XY plane; and the numerical control case is used for centralized control of the light, machine and electricity of the whole safety check device; the remote terminal is used for controlling the space position of the electric control robotic arm, the scan speed of the flying-spot scanning module and the sampling rate of a detector array, and displaying scanning results in real time. Compared with the prior art, the problem that the contraband items such as drugs and explosives hidden in the inner interlayer of small vehicles are difficult to check is solved by the device, and the difficulty of the large detection workload, the long detection time and the tedious detection process for the hidden drugs in the vehicle of the drug enforcement front line is overcome by the application of the safety check device.

Description

technical field [0001] The invention relates to the field of X-ray backscatter imaging security inspection, in particular to a mobile in-vehicle panoramic X-ray backscatter scanning security inspection device. Background technique [0002] At present, there is a lack of direct and effective security inspection technology for hidden drugs, explosives and other contraband inside the car interior, such as hiding drugs and explosives in the interlayer of leather seats and plastic interior. Manual inspection is usually used to check by opening the interior interlayer or leather seats, which largely relies on the experience of the security inspectors and has great uncertainty, so the accuracy of the search is extremely low. [0003] X-rays are very penetrating and can detect drugs or explosives hidden inside a car. Usually X-ray security inspection technology includes perspective imaging and backscatter imaging. Perspective imaging uses the difference in X-ray absorption coeffic...
