I believe that everyone is familiar with security checks. Security checks are required when taking subways, trains, and airplanes. No matter what kind of transportation you take, you always have to pass through a walk through metal detector when you pass through the security check. There is often a "beep" sound when you pass. After entering, the security check personnel will also check the passengers. People have long been accustomed to it. But what exactly is this series of actions detecting? Next, let's take a look at the introduction of the walk through metal detector.
Here is the content list:
What is walk through metal detector?
How to identify the quality of walk through metal detectors?
The walk through metal detector is a device dedicated to detecting whether metal objects are carried on the person. We see this kind of product in airports, stations, and other places, and the setting of security metal detectors greatly improves its safety. The principle used by the walk through metal detector to detect metal is magnetic field induction technology. When it is working, a stable magnetic field distribution will be formed inside the walk through metal detector. If there is a metal substance passing through the door, it will destroy the magnetic field of the door itself, which will be sensed by the metal detection door and an alarm will sound. At the same time, the walk through metal detector is divided into different areas, the more common ones are six and eight, and there are higher ones such as twelve and twenty-eight. When the human body carries metal through the walk through metal detector, where the metal is, the alarm in the corresponding area will sound. In this way, the security personnel can find the metal objects carried by the human body more quickly and accurately.
The door frame metal detector is the first-line equipment and facility for the safety of the control area, which is used to check and filter harmful and offensive metals such as knives, guns, bombs, etc. In addition to being the necessary security equipment for various airports, there are also prisons, large sports venues, expo halls, banks, courts, mints, treasuries, government agencies, embassies, military and police units, telecommunications rooms, various precious metal industries, electronics, etc. Industries, entertainment places, etc. These places need to protect the safety of the masses and places are widely used to avoid hijacking, security, and theft incidents.
The walk through metal detector imported from abroad in the early days of China was mainly used in the security of airports. Due to factors such as high price and high maintenance costs imported from abroad, the purchase of many enterprises and institutions that demand walk through metal detectors is limited. China successfully developed and put it on the market in 1993, and its production and sales continue to increase. To standardize production, the Ministry of Public Security has successively issued two sets of mandatory production and inspection standards, GB15210-1994 and GB15210-2003. Stricter and more detailed requirements have been imposed to meet the needs of security checks in modern public places.
Because the market of this kind of product is very imaginative and attractive, the manufacturers of walk through metal detectors in China are booming. At present, there are more than a dozen enterprises producing walk through metal detectors in China, and the products are sold all over the country. Due to the production technology of various walk through metal detector manufacturers, there is a large gap in product quality. The products of some enterprises can only pass the inspection of the old national inspection standard "GB15210-1994", but cannot pass the inspection of the new national inspection standard "GB15210-2003". The main reason is that the company's production technology, raw material quality, and production process are inferior, so it has not obtained the production license issued by the local public security bureau, that is, it has become what the public calls "three noes" products. But these kinds of inferior and inferior products are flooding the market with extremely low prices. In addition, in the process of advertising and sales, the functions of the equipment and the functions that are difficult to verify are deliberately exaggerated, causing misunderstandings to users and preventing users from truly choosing safe, qualified, suitable, and effective products.
