The principle of the supermarket swing gate anti-theft system

Today, science and technology are increasingly developed, and everything is about efficiency. The traditional anti-theft method of retail stores using human resources to monitor shopping malls is no longer suitable. The application of supermarket anti-theft systems is very common. Then, what is the principle of the supermarket anti-theft system? The following is a brief introduction by the Shenzhen Yuanhao Intelligent Equipment Co., Ltd. to introduce the principle of the supermarket anti-theft system.
It can be divided into radio system, electromagnetic wave system, microwave system, frequency division system, intelligent system and acousto-magnetic system by means of detection signals applied by supermarket anti-theft system.
Acoustic magnetic system
The tuning fork only causes resonance when the oscillation frequency is the same. Acoustic magnetic system (Acusto Magnetic) is the application of this physical principle to achieve almost zero false positive operation. When the acoustic magnetic system tag fixed on the commodity enters the detection area of ​​the system, it will resonate, but only receive at the receiver. The alarm is issued after four consecutive resonance signals (every 1/50th of a second).
The characteristics of the acousto-magnetic system are high anti-theft detection rate, almost zero false alarm, good anti-interference, and the protection export width can reach 3.5 m. There are two kinds of anti-theft tags, which can protect most types of goods in the mall. And can degaussing repeatedly, even if the system is still working properly next to the POS cash register.
Acoustic magnetic systems include vertical systems, channel systems and concealed systems. There are more than 10 models to choose from. They can be widely used in department stores, supermarkets, specialty stores, audio-visual stores, grocery stores, pharmacies, and also in Office building and other environments.
Radio system
The radio system (Radio Frequency, RF) uses radio waves as the signal for transmitting and receiving, and the detection frequency ranges from 7.x to 8.x megahertz. The biggest advantage of the radio system is that the system cost is very low and the installation is convenient. However, because the anti-theft tag is a toroidal coil type, the system is susceptible to interference from some items, such as electronic products such as cash registers, metal objects, etc., causing false positives or failures of the system.
The radio system has both soft and hard labels that protect most of the items in the mall. The distance between the two supports is generally not more than 0 9 meters, and is usually used in shopping malls with only one import and export. The radio system has two types, vertical and channel, for protecting department stores, clothing stores, supermarkets, etc.
Electromagnetic wave system
The electromagnetic system (Electromagnetic System) uses electromagnetic waves as a detection signal.
The electromagnetic wave system has the smallest label, the label price is also cheap, and the degaussing can be repeated, but it is susceptible to false alarms due to the influence of magnetic or metallic substances. The width of the protected exit is generally around 0.9 meters. The system does not affect magnetic items such as audio tapes, video tapes, and magnetic cards.
The new generation of channel-type electromagnetic wave system is a software-controlled electronic anti-theft system that uses digital processing technology and degaussing system, cashier monitoring and closed-circuit television monitoring system. The use of a fast degaussing plate enables repeated degaussing and high system cost. Electromagnetic wave systems are available in both vertical and channel types. The application environment is mostly in libraries, bookstores, sound stores, hotels, supermarkets, etc.
Microwave system
Microwave System uses microwave as the detection signal, which is not easily interfered by the surrounding environment. It can be flexibly concealed (such as hidden under the carpet or suspended from the ceiling), which has the advantages of being suitable for interior decoration and beauty. However, due to the large scope of Shengying, it is not possible to arrange goods in a certain area. This will limit the use of space for merchants with a lot of land, so it is suitable for large department stores and large music stores and fashion stores.
SplitFrequency is an anti-theft system that uses high-tech crossover technology and ultra-low frequency radio wave signals. When an anti-theft tag enters the detection area, the tag receives the signal transmitted from the transmitting device, divides it into half, and then transmits the half-divided information to the receiver, only when the receiver receives half of the signal. An alarm is issued to effectively avoid interference from other radio waves.
The system has light weight, small size, low price, stable performance, high detection rate, good anti-interference, and is not easy to cause false alarms. The products are available in both vertical and concealed versions. It is an ideal anti-theft system for clothing and clothing stores.
Smart system
The unique technology of the smart system application is a system that is internally controlled by an integrated circuit, battery driven, and integrated with hard tags and alarms. The system automatically issues an alarm when the tag is picked up or taken out of the store with the item.
The system protects goods throughout the mall from false positives and labels that can be reused without damaging the merchandise. Used to protect valuables such as fashion, leather, robes, etc.
Failure principle system
The anti-theft system of the destruction principle is a hard tag or a magnetic lock. The hard tag contains ink. When the thief tries to remove the hard tag, the hard tag will eject ink, contaminating the merchandise and the thief's body. The magnetic lock is not easy to dismantle. Forcibly dismantled will destroy the goods. It is easy to use, has a good deterrent effect, and has low cost. It is applied to clothing, glasses, jewelry, ties, silk and other commodities. Tags can be reused.
What is the principle of the supermarket anti-theft system? The above is the introduction of the principle of the supermarket anti-theft system. The installation of supermarket anti-theft system can reduce the loss rate of goods, reduce employees, assist management and increase profits.
