Problems solved by technology

In our country, luggage has been used to detect the human body through the safety door and manual operation. This detection method is not only slow, but also separates people from luggage. Sometimes there are embarrassing situations such as face-to-face body searches, undressing, and footwear removal. This brings inconvenience to the inspected personnel and often causes some unnecessary disputes; in addition, the detector can only be sensitive to metal
At the same time, most of the safety testing equipment adopts the direct transmission scanning method, which has a large radiation dose and is harmful to the human body.

Embodiment Construction

[0014] The principle, structure and working process of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] Fig. 2 is a schematic diagram of the principle structure of the humanized human body and suitcase detection equipment provided by the present invention. The detection equipment includes an anti-scatter X-ray detection device 5, a transmission X-ray detector 4 and an information image processing system 9. The anti-scatter X-ray detection device contains an X-ray tube 14, a collimator 15, and a flying spot scanning drum 16 and a first backscatter X-ray detector 17, a second backscatter X-ray detector 18, a conveyor belt and a drag mechanism 10 for dragging the belt, and the backscatter X-ray detection device 5 adopts two one, and relatively placed on both sides of the conveyor belt 3; the transmission X-ray detector 4 is placed on either side of the conveyor belt, the transmission X-ray detector and the backscatter X...

Abstract

The human friendly human body and hand carry suitcase inspection equipment particularly uses the flying spot scanning and back diffusion scanning X ray safety inspection. It comprises two reflective X ray inspection device, one transmission X ray detector, information image handling system, conveyer belt and extraction belt mechanism. It can provide safe, friendly and reliable safety inspection of human body and suitcase, with high sensitivity. It also enjoys low radiation and scanning point, with less harm to human body.

Description

technical field [0001] The invention relates to an X-ray safety detection device, in particular to an X-ray safety detection device using flying-spot scanning technology and back-scattering technology. Background technique [0002] In important places related to the safety of the country and people, such as railway stations, airports, ports, and customs, safety inspections must be carried out. Especially in recent years, terrorist activities have been rampant and drugs have become a public nuisance. Therefore, the safety detection technology has been paid more and more attention by the governments of various countries. Safety detection in the prior art usually adopts technical means and equipment such as safety gates, safety passages, metal detectors, luggage detectors, luggage and parcel detectors, and drug detectors. In our country, luggage has been used to detect the human body through the safety door and manual operation. This detection method is not only slow, but also...
