As a common equipment for security inspection, security gates are used to ensure social safety and personal safety through safety inspection of passers-by. The use of security gates is mostly in public stations, airports, subway stations, schools and other places of safety.
The price of security gates in the market is indeed different, why this phenomenon exists, let's make a concrete analysis and analysis together.
First of all, let's look at the factors that affect the price difference of the security inspection machine. The quality of the security inspection machine equipment, the quality of the security inspection door, the service of the manufacturer, the famous brand of some manufacturers, a lot of manufacturing parts are imported, the original manufacturing, the quality of the equipment, and the perfect after-sales service. Therefore, the price will be higher than the market price.
Again, if the security machine is an irregular manufacturer, the raw materials are inferior, and all aspects of performance are not up to the standard, so many manufacturers use low prices to stimulate consumption, but more people pay attention to price and do not pay attention to quality, so they are willing to buy security equipment at a price lower than the market price, so some of them have. The price of equipment is high, some equipment is low, and there is a big difference in price.
Metal detectors can be used to detect various metal objects. Metal detector is an electronic instrument for detecting the presence of nearby metals. The simplest form of metal detector consists of an oscillator that generates alternating current through a coil that generates alternating magnetic fields. If a conductive metal is close to the coil, it will generate eddy currents in the metal, which will generate its own magnetic field. If another coil is used to measure the magnetic field (used as a magnetometer), changes in the magnetic field caused by metal objects can be detected. Metal detectors can be used to locate metal inclusions hidden in objects or metal objects buried underground. They are usually composed of hand-held devices with sensor probes that can sweep across the ground or other objects. If the sensor is close to a piece of metal, the pointer on the pointer moves, or the detection instrument will show changes, the metal detector will be used for security checks at access points in prisons, courts and airports to detect hidden metal weapons on the human body.
Metal detectors are widely used in mineral exploration and other industrial applications. Uses include detection of mines, detection tools and other weapons, geophysical exploration, Archaeology and treasure hunting. Metal detectors are also used to detect foreign bodies in food, and in the construction industry to detect steel bars in concrete and pipelines and wires buried in walls and floors.
Introduction of Electronic Product Detection Door
Electronic product detection door, mobile phone detection door according to customer needs, the development of a device for mobile phones, notebooks, digital cameras, cameras, recording pens and other electronic equipment to detect, the system can be mobile phone standby, shutdown, boot, remove batteries, remove SIM cards and other states to detect personnel. Whether to carry a mobile phone and other electronic products detection system. There are 10 probes on each side of the mobile phone detection door, a total of 20 probes. The only one in the world can reach 70 centimeters wide. The inspected person can enter and come out. The passing speed is 1 second, and the detection rate is as high as 99%.
Principle of Detection Door for Electronic Equipment
The system adopts six-layer technology principles of metal classification detection, molecular detection, integrated metal residual detection, electromagnetic eddy current technology, electromagnetic identification induction, analog signal to digital signal processing.
Integrating weak signal detection technology, precision filtering technology, finite element analysis technology, gradient measurement technology, expert system, self-adaptive recognition technology, we can judge the objects carried by the inspectors according to the eddy current and electromagnetic identity information of different metal objects, and accurately detect the location of the carrying equipment.
