Ultra-low-dose X-ray human body security inspection system with double exchange platforms

Abstract

The invention relates to an ultra-low-dose X-ray human body security inspection system with double exchange platforms, the system comprises an X-ray source, a collimation part, an inspection channel, an X-ray detector, an image acquisition and processing device, a control device and an operation console, wherein the inspection channel comprises an inlet, an outlet and a mobile inspection platform, the mobile inspection platform is a dual-circulation platform and comprises a first platform, a second platform, two upper tracks, two lower tracks, a platform driving mechanism, a platform lifting link mechanism and a base, the first platform and the second platform are respectively movably mounted on the upper tracks and the lower tracks and move along the reverse directions of the upper tracks and the lower tracks under the drive of the platform driving mechanism arranged on the outer side, and the upper and the lower positions of the first platform and the second platform on the lower tracks and the upper tracks are exchanged through the platform lifting link mechanism after running in place at each time. The ultra-low-dose X-ray human body security inspection system can double improve the inspection capacity and the customs clearance efficiency, have smooth running, good linearity and uniform movement speed and greatly improve the X-ray inspection imaging quality.

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 double exchange platforms 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. Fo...

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 on 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
