Electronic door locks enter the password through the digital keys on the phone keyboard. If the password is the same as the internal password, an output of an electrical signal is output to drive the door in the form of driving the electromagnet.In this way, you only need to remember the password to complete a unlocking process.
Electronic lock price
I. Price Quotes 1. The price of hotel door locks and hotel locks is relatively single because of the functional requirements of the lock. The price is about 160-450 yuan per number.2. The electronic lock used in the office is mainly a password lock. The price of the electronic locks used in the office is about 530 to 1,200 yuan each. If the electronic lock price of the attendance function is about 600-1200 yuan.3.

Electronic lock principle
Electronic lock, it is also based on the 51 series single -chip microcomputer, with the corresponding hardware circuit, completes the password settings, storage, identification and display, drives electromagnetic actuators and detects its driving current value, alarm signal sent by the receiving sensor, sending the alarm signal, sending sent by the receiving sensor, sending the alarm signal, sending sending, sending itData and other functions.The single -chip machine receives the code to the key, and is compared with the password stored in EEPROM. If the password is correct, the electromagnetic actuator is unlocked; if the password is incorrect, the operator will be allowed to re -enter the password, which can be entered up to three times; if all three times, you will beIncorrectly, the single -chip microcomputer called the intelligent monitor through the communication line.The single -chip machine sends each unlocking operation and the driving current value of the electromagnetic actuator at this time as the status information to the intelligent monitor. At the same time, the alarm information received from the sensor interface is also sent to the intelligent monitor as the basis for intelligent analysis.
