Brief introduction to the principle of induction door lock

Lead: With the continuous progress of science and technology, people's living standards are constantly improving, and people's awareness of prevention is also constantly increasing. As a result, various anti-theft devices and safety devices have appeared, and induction doors have also begun to be used in some hotels, hotels, including automobiles and other industries. The main principle of this kind of induction door is simply that one side sends out a signal, and the other side reacts according to the signal through the internal coil, and then automatically opens the door.

Induction door lock

Induction door lock is a new type of security and anti-theft equipment rising in recent years. Like the remote controller, it can also receive information, process information and respond through infrared sensors. Generally, it will be used in hotels, guesthouses and some high-end clubs. Generally, it is smart in those places. One card can solve all problems without all kinds of keys. The induction door lock will be composed of three parts, namely, radio frequency door lock, induction lock and induction door lock system. A complete induction door lock needs their cooperation. In foreign countries, the popularity of inductive door locks has been very extensive, but the domestic situation is not so optimistic. There are not many industries that install induction doors in China, and they are still in the primary stage. Of course, with the continuous development of some high-end locks, the prospect of inductive door locks is still bright. And our country's investment in this field is slowly increasing. Because of the needs of the market, the market for inductive door locks is also growing slowly.

Principle of intelligent induction door lock

Induction door locks include intelligent door locks, in which the induction principle of intelligent door locks is that there is a coil in the sensor of the door, which is similar to the primary coil in the transformer, and then there will be a coil in the door card, which is also equivalent to the secondary coil in the transformer. When the card is close to the door, that is, when the two coils are close to each other, it will move to generate current, and at the same time, the door will ask for a signal, and the card will respond, which meets the conditions for opening the door.

Principle of induction door lock

The induction door lock can not only open the door by emitting infrared induction, but also someone recently invented an automatic induction Bluetooth door lock. The main principle is that a Bluetooth chip can be installed on the door, and our smart phone will also have Bluetooth function. The signal is transmitted from the mobile phone to the door through Bluetooth, and then the door can respond according to the received information, thus completing the whole process of sensing the door, mainly using Bluetooth technology, avoiding the trouble that people forget to bring their keys.

In a word, the market for inductive door locks is rising. The principle of inductive door lock is also updated day by day. From infrared field to sound field, including some Bluetooth technologies, are the main principles of inductive door locks, which are to design inductive door locks through some physical factors.
