It is not only fast and convenient, but also safe and accurate, which sets up a barrier for our express security. How can the security inspectors identify dangerous goods through the express security inspection machine? Today Suzhou aoteng Electronic Technology Co., Ltd. will give you a detailed explanation:
1、 How does express x-ray screening machine find contraband?
When the inspected goods pass through the express x-ray screening machine, they can present images of different shapes and colors on the monitor. The key to finding the prohibited goods is that the express security inspection personnel can master these characteristics skillfully.
2、 How to identify the contraband express x-ray screening security inspection machine?
1. The X-ray image identification of the gun express security machine: under the monitor, the metal is dark blue and red, while the gun is mostly made of steel, so the clear gun body outline appears on the monitor of the gun express security machine. The simulation gun is made of aluminum alloy, the metal density is not as large as the real gun, and the structure of the gun barrel is different from the real gun. There is a plug in the barrel of the simulation gun, so the X-ray image of the express security inspection machine is not completely dark blue and red, only there are some blue and red in the single edge of the gun. As for toy pistol and plastic gun, green or orange appears on the monitor of express x-ray screening machine. In this way, the color and structure of the X-ray image of the express security inspection machine can distinguish the real gun, the simulation gun and the toy gun.
2. The X-ray image identification of the controlled knife express x-ray screening machine: the controlled knife includes dagger, spring knife, self-locking knife and ethnic minority technical sabre. Without clamping and hiding, the knife has obvious shape and outline on the monitor of express x-ray screening machine, and its color is mostly dark blue and green.
3. X-ray image recognition of explosives express security inspection machine: explosives are mainly composed of explosives and fuse bodies. Explosives are mostly organic substances. The X-ray system of the express x-ray screening machine gives the organic substance orange. According to the variety, density and quantity of explosives, orange from light to deep can appear. Some explosives have specific shapes and structures, such as bulk TNT, hardbound ammonium nitrate explosives, etc., which are relatively easy to find.
4. To identify the X-ray image of the drug express security machine: heroin is powder or regular block under normal pressure, and the special orange appears on the monitor of the X-ray system of the drug express x-ray screening machine.
