What is the principle of induction lock card lock? What is the principle flow of credit card lock electronic door lock? Inductive lock schematic process details. Electronic sensor door lock is widely used in hotels, hotels and other occasions, electronic locks, IC card sensor door locks, magnetic card sensor door locks, etc., with automatic sensing unlock, automatic locking function, mostly through the card to open the door, convenient centralized management . This article mainly describes the working principle of the induction door lock card lock.

Electronic Induction Lock Workflow
Inductive door locks are usually opened by a magnetic card or IC card to open the door without contact. The room card serves as the key to the door lock.
The principle of inductive door lock is based on the RFID technology based on the non-contact unlock electronic lock, RFID features non-contact automatic identification technology, can achieve non-contact two-way communication, so as to achieve the purpose of identification and data exchange, do not Manual intervention, the operation is very simple.
The basic part of the RFID system consists of a tag, a reader, an antenna, and a corresponding data transmission and processing system.
Induction lock card lock lock working principle introducedInductive door lock is the process of recognizing internal information through card swiping, identifying the internal information, and automatically unlocking after matching. The sensing area is the core part of the door lock, and there is a sensor, that is, a swipe area.
The built-in coil of the inductor, which is generally made of copper wire, is continuously oscillating under power-on conditions, similar to the primary coil of the transformer. There is also a coil in the sensor card, which is equivalent to the secondary coil of the transformer.
The two are close to each other. Within the sensing range, the coil is coupled with a shock to generate a current, and a cartoon is sensed. At the same time, an inquiry signal is sent. After the response, the condition is met and the door lock automatically opens.
In general, the inductive door lock senses to the human body through infrared or micro-blog, the cardholder's hand approaches the sensing area, activates the door lock CPU, the circuit transmits the electromagnetic wave signal through the antenna, the card returns the response signal, passes the Manchester code decoding process, Identification card ID and other information, in line with the unlock conditions, drive the mechanical door lock to perform the unlock operation, you can achieve a complete working process.
The above is a smart lock Chinese network Xiaobian finishing published induction locks credit card lock working principle introduction, more lock knowledge, please pay attention to this column related articles!
