Ultralow-dose X-ray human body security check system with two channels

Abstract

The invention discloses an ultralow-dose X-ray human body security check system with two channels, which comprises an X-ray source, an alignment part, a check channel, a mobile check platform, a platform driving mechanism, an X-ray detector, an image acquisition and processing device, a control device and an operating console, wherein the check channel comprises two channels, namely a right channel and a left channel which are in parallel with each other; the left channel inlet of the left channel is at left; the outlet of the left channel is in front of the inlet of the right channel; the right channel inlet of the right channel is at right; the outlet of the right channel is in front of the inlet of the left channel; the reciprocating mobile check platforms are arranged between the inlets of the left channel and the left channel as well as the outlets of the right channel and the left channel; the mobile check platform is driven by a platform driving device to convey checked objectsto the right end or left end of the channel in a cycling and reciprocated mode through the inlet of the left channel or the inlet of the right channel after the check is finished; and the checked objects go out of the check channels from the outlet of the left channel or the outlet of the right channel. The invention can improve the equipment inspection capacity and the clearance efficiency in a duplication mode.

Description

【Technical field】 [0001] The invention relates to public security inspection equipment used in airports, customs and other occasions where security inspection is required, in particular to an ultra-low-dose X-ray human body security inspection system with dual channels that can effectively improve inspection efficiency. 【Background technique】 [0002] At present, terrorist activities and drug-trafficking crimes are becoming more and more rampant around the world, which seriously endanger the public safety and normal life order of the society. To this end, countries around the world have continuously strengthened their efforts to combat and prevent such criminal activities, such as strengthening security checks in important places such as airports and customs, and installing security check equipment for human bodies and bags at the entrances and exits of various important departments. For luggage, X-ray fluoroscopy imaging technology is mainly used at present. For the inspec...

Problems solved by technology

It takes at least 15 seconds to inspect a human body, so the inspection efficiency is low and the inspection cycle per capita is long

For densely populated airports, subway entrances, etc., it is necessary to set up multiple such devices, and because of its high price, the price of a single device is more than 1 million yuan, and the configuration of multiple devices needs to occupy a large amount of space and increase a lot of purchase costs. It is uneconomical and impractical, and it is difficult to promote and apply it in a large scale

[0003] On the other hand, in the above-mentioned system, the manned skateboard is dragged by the conveyor belt to realize reciprocating movement. Since the conveyor belt is flexible, its reciprocating speed cannot be very uniform, and the middle part of the conveyor belt will inevitably sink under heavy load, causing the When inspectors pass through the X-ray scanning area, they do not actually move in a straight line at a uniform speed, thus affecting the imaging effect
