Week X-ray reciprocating security inspection device

Abstract

The invention relates to a week X-ray reciprocating security inspection device, comprising an X-ray transmission device, an X-ray signal acquisition device, a computer image processing and control system and an operating console, wherein the X-ray signal acquisition device and the X-ray transmission device are arranged on two sides of an inspection channel, respectively; the inspection channel is an open inspection channel, which comprises a shelf, a chain-drive mechanism and a luggage car; one side of the luggage car is provided with a rail mechanism slip and the other side of the luggage car is provided with a roller mechanism slip. The invention adopts an open inspection channel, people can get on or get off and luggage can be loaded or unloaded from both sides of the inspection channel, the luggage car can be dragged steadily to make a uniform linear movement on the guide rail by a reduction motor and a conveyor chain, the full automatic operation can be realized under the instruction of a control system, a photoelectric sensor and a Hall sensor, and thus the imaging quality and the inspection efficiency can be increased, and the device has low failure rate and small noise.

Description

[0001] technical field [0002] The invention relates to public safety inspection equipment, in particular to a device for safety inspection of hidden objects inside and outside weak X-ray objects. [0003] Background technique [0004] At present, the existing X-ray inspection equipment inside and outside the object generally uses the position of the light source to place the X-ray source at a long distance, and the X-ray beam illuminates the human body from the upward side. In terms of imaging, the traditional X-ray imaging technology is used to process the collected energy signals, X-ray perspective is performed when the inspected item or person passes through the inspection channel, and the gray level and graphic outline of the perspective image are used to identify hidden objects. The inspection equipment mainly adopts a one-way inspection channel, such as a manned slide channel and a reciprocating cargo trolley channel. The movement of the manned skateboard or troll...

AI Technical Summary

Problems solved by technology

The movement of the manned skateboard or trolley in this inspection channel is driven by belts, powered by electric rollers, driven in one direction, and the return journey uses spring torsion elastic force. The problem in use is: the rebound of the trolley is not in place, and artificial It needs to be assisted to return to the position, the operation is unstable, the failure rate is high, and there is no time to return, only one-way inspection can be performed, and the imaging quality and inspection efficiency are low
