Working Principle for

the Security Inspection Equipment

What is the working principle of the security inspection machine? Our company is a supplier of security products and security solutions. Our company has collected a lot of information about this aspect, explain the working principle of the security inspection machine in detail.

The security check device at the station is called "emergency check instrument". The working principle is to use a small dose of X-rays to irradiate the prepared items, use a computer to analyze the transmitted rays, and analyze the properties of the penetrated items according to the changes in the transmitted rays. The X-ray beam passes through the object on the conveyor belt, the X-ray is absorbed by the object, and finally bombards the semiconductor detector installed in the channel. The detector converts the X-rays into signals, which are amplified and sent to the signal processing chassis for further processing, which is then displayed on the display screen. "No matter how many layers the bag has, the X-rays can penetrate and reveal the contents of the bag layer by layer.

There are generally four inspection methods in safety inspection:

First, X-ray security equipment, mainly used to check passengers' luggage items. After passing the inspection, the staff will stick a sticker "XX Airport baggage security check" on the baggage, and then it can be checked in or carried on board

Second, the detection and inspection door is used for the physical examination of passengers, mainly to check whether passengers carry items;

Third, the magnetic detector, also known as the portable detector, is mainly used for close inspection of passengers;

Fourth, Manual inspection, that is, manual search of passengers' luggage by security staff and pat-down by male and female inspectors respectively.
