Security inspection machine, also known as security inspection instrument, security inspection X-ray machine, luggage security inspection machine, channel X-ray machine, physical inspection X-ray machine, X-ray luggage security inspection machine, X-ray foreign body detector, X-ray security inspection machine, X-ray luggage detector, triple product detector and danger detector. An electronic device that sends checked baggage into the X-ray inspection channel through a conveyor belt to complete the inspection. 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.
