Composition of book anti-theft system
The book anti-theft system is a self-defense device for books. It gives books a self-defense ability through electronic means, that is, once someone tries to take books out of the store without permission, it will notify the system and give an alarm. This fundamentally changed the passive state of all previous anti-theft systems in monitoring anti-theft, so that anti-theft measures can be implemented on every commodity.
The book anti-theft system consists of a detection door, a detector host, a charge-discharge sensor, a back detector and a magnetic stripe.
Detection gate: It consists of a sending gate, a receiving gate (single channel) or a sending gate and two receiving gates (dual channels). Its basic principle is that the transmitting antenna emits a scanning band and a scanning area is formed between the transmitting antenna and the receiving antenna. There is an effective magnetic stripe in this area, and the receiving antenna receives the signal, triggering the detector host to alarm.
Detection host: It is used together with the detection door to form a system.
Charger-desensitizer: used to magnetize or degauss the composite magnetic stripe in the book.
Recheck instrument: used to check whether the magnetic stripe in the book is in good condition.
