What do the different colors of the security machine represent?

Abstract: Security inspection machine is a very common equipment in our life, which is widely used in airports, passenger stations, subway stations, high-speed rail and other places. The security inspection machine is an X-ray inspection instrument, which sends the checked suitcase to the X-ray inspection exit for inspection by means of conveyor belt. When different luggage passes through the security inspection machine, many different colors will be displayed on the screen of the security inspection machine. What do these colors represent? First, the introduction of security inspection machine

Security inspection machine, also known as security inspection instrument, includes security inspection X-ray machine, baggage inspection machine, passage X-ray machine, physical inspection X-ray machine, baggage inspection X-ray machine, foreign body inspection X-ray machine, baggage inspection X-ray machine, three-product inspection machine and danger detection machine.

Security inspection machines are widely used in airports, railway stations, subway stations, bus stations, government buildings, embassies, conference centers, exhibition centers, hotels, shopping malls, large-scale events, post offices, schools, logistics industries, industrial inspections and so on.

Second, the working principle of the security inspection machine

The "golden eye" of the security inspection instrument is realized by an X-ray machine, which is an electronic device that sends the checked baggage into the X-ray inspection channel by means of a conveyor belt. When the luggage enters the X-ray inspection channel, it will block the package detection sensor, and the detection signal will be sent to the system control part to generate an X-ray trigger signal, which will trigger the X-ray light source to emit an X-ray beam. The fan-shaped X-ray beam passing through the collimator passes through the detected object on the conveyor belt, and the X-ray is absorbed by the detected object, and finally bombards the dual-energy semiconductor detector installed in the channel. The detector converts X-rays into signals, and these weak signals are amplified and sent to the signal processing cabinet for further processing.

3. What do the different colors of the security machine represent?

X-ray security machine works by imaging objects with X-rays. This X-ray can penetrate glass, ceramics, metals, liquids, wood, cloth and other objects. After penetration, the radiation reaches the plate under the conveyor belt. Then the ray signal is converted into a computer image.

Due to the different materials of different articles, the degree of X-ray penetration is different, and the color of the formed image is also different. On the computer screen of the security inspection machine, organic substances such as food and plastic are orange. Books, ceramics, etc. It is displayed in green, and the mixture is also displayed in green, such as stainless steel products. Metal is blue, while stun guns and knives are different shades of blue. Red indicates that the item is heavy metal or has strong resistance to X-ray penetration. In addition, the items represented by each color and different color saturation have a more specific division. Specially trained security personnel can tell whether the luggage contains contraband by the color on the screen.
