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.
Is the electronic lock safe?
The security of the electronic lock depends on many factors, the security factor of the password recognition system, and the safety factor of the lock core.The electronic lock of Gujia lock industry has a unique password recognition system, which can effectively improve the security of locks. In addition, the lock core uses the blade short turbine structure, which greatly improves the security protection ability.Therefore, he is relatively safe.Among several electronic door locks, the stability of the radio frequency card electronic door lock is significantly higher than that of other electronic door locks.The magnetic card is afraid of a strong magnetic field, and the IC card is afraid of oil, dust and static electricity (especially in dry weather with wool spinning), and the radio frequency card has the characteristics of full seal, waterproof, anti -static, and dust -proof.In terms of card reading, only the RF card reading card is not exposed, and its service life is the longest.
Electronic lock classification
I. Wired locks can be divided into the following categories according to the input password: 1. The keyboard (or combination button) is used to enter the unlock password, which is convenient for operation.Internal control circuits often use electronic lock -specific integrated circuits ASIC.2. The dial -dial type uses a mechanical dial switch to enter the unlock password.Many key electronic locks can be transformed into dial -dial -type electronic locks.
Electronic lock repair
1. When the legal card opens the door and the alarm is shining, there will be 8 short sounds of "嘀", and the door lock cannot be turned on. At this time, the solution is to replace the battery.2. When the system logo is not red, there will be a "嘀" 4 short sound. The door cannot be opened because the system logo is wrong. Replace the system card.3. The yellow light will appear when the mechanical is locked. At this time, the door cannot be opened, and the door opens the door through the emergency card.

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. Due to the higher demand for security and appearance, the corresponding household electrons are higher due to the higher demand for safety and appearance.The price of a household sensing electronic lock is about 700-2300 yuan. The price of a password lock is about 1300-3000 yuan. The price of a fingerprint lock is about 2000-4800
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.
