Safety inspection system

Abstract

The invention provides a safety inspection system. The safety inspection system comprises a supporting main body comprising a first detection channel and a second detection channel, a shielding device arranged between the first detection channel and the second detection channel, a first ray emission device arranged on one side, far away from the second detection channel, of the first detection channel in a manner of emitting detection rays to the first detection channel, a first detector device arranged in the first detection channel to receive the detection rays emitted from the first ray emission device, a second ray emission device arranged on one side, far away from the first detection channel, of the second detection channel in a manner of emitting detection rays to the second detection channel, and a second detector device arranged in the second detection channel to receive the detection rays emitted by the second ray emission device. The safety inspection system can fulfill the aims of improving the imaging quality of a generated radiation image, facilitating substance identification of the radiation image and enabling the logic of the image to be clear.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a safety inspection system. Background technique [0002] At present, important public places at home and abroad, such as airports, customs, rail transit stations, etc., pay more and more attention to the safety inspection of bulk items, especially the inspection of items in the field of air cargo is more stringent. [0003] In order to improve the efficiency of security inspection, the radiation image system using X-ray machine as the radiation source is widely used as a mature security inspection technology. For example, by installing a security inspection system including the above-mentioned radiation image system at the entrance of the airport security inspection channel, other item inspection sites and inspection crossings that require security inspection of items, it is possible to scan and detect items such as suitcases to eliminate potential safety hazards.

Problems solved by technology

[0004] However, since the two detection channels share a side-view optical machine, in order to avoid the problem that the radiation images formed by scanning the detection items of the two detection channels are superimposed and the material identification of the detection items cannot be performed, the detection items of the two channels cannot be Carry out scanning inspection at the same time, but use the time-sharing inspection method to scan and inspect the inspection items in the two inspection channels separately, which will affect the passing efficiency of the security inspection, especially when the passenger flow is large, it will cause the accumulation of passenger flow
