If passengers pass through the security gate of the train station, the security gate can detect what is prohibited at the moment: such as knives, but according to regulations, knives like kitchen knives, scissors, fruit knives and razors can be handled and mailed as luggage even if they are on the day of arrival It is forbidden to carry. The above rules also apply to carving knives, knives, spears, swords, halberds, axes, chisels, hammers, cones, sticks with sharp or spiked nails, and iron-tip climbing sticks used in literary and artistic units.
If a passenger accidentally carries the above-mentioned items with him, he can put them in the tool disposal box set up at the security checkpoint in an emergency, and can ask the security checker to go through temporary storage procedures. Many people will ask, can the metal detection security door detect drugs and explosives carried by the human body? In fact, whether it is domestic or imported, the metal detection security inspection door cannot detect whether the human body carries drugs or explosives and other prohibited article.
Because the principle of metal detection security door is to detect metal by magnetic field induction, it detects metal cutting magnetic field lines. Prohibited articles such as drugs and explosives do not contain metal components and do not meet the detection conditions for metal detection safety inspection doors. Therefore, metal safety inspection doors cannot be used for detection.
To put it bluntly, the metal detection security inspection only detects metals, and only the sensitivity of the inspection door is high enough that ordinary metals can be detected. The detection sensitivity requirement depends on the application. Of course, the higher the sensitivity, the better the price. It is best to choose the safety inspection door for metal exploration according to your needs, what kind of metal you need to detect and how much metal you need to detect, not just sensitivity. In addition, we should also choose a strong security door manufacturer.
