With the increasingly developing economic development, improving living standards of people needs higher and higher security level, while due to the external Third World war, terrorist extremists and other factors, domestic airports, railway stations and mass rally places are equipped with higher and higher check security device.
The performance of security equipment has enhanced a lot. How to distinguish explosives drug guns and other dangerous goods, we can know from the principle of security machine.
The security machine is an electronic device that checks the baggage into the X-ray inspection channel by conveyor belt. When baggage gets into the X-ray inspection channel, it will block the package detection sensor, the detection signal is sent to the system control part, resulting in X-ray trigger signal, trigger X-ray radiation source X-ray beam.
The X-ray beam passes through objects on the conveyor belt, and the X-ray is absorbed by objects and finally bombards the semiconductor detector installed in the channel. The detector converts the X-rays into signals, and these weak signals are amplified and sent to the signal processing chassis for further processing. These signals are processed and displayed through the display screen.
