What is the principle of electronic lock? Electronic lock price quotes
Household electronic locks are household door locks that have emerged in China in recent years. Let's take a look at the principle of electronic locks and the price of electronic locks.
What is the principle of electronic lock?
Electronic lock, it is also based on 51 series single-chip microcomputer (AT89051), with corresponding hardware circuit, complete password setting, storage, identification and display, drive electromagnetic actuator and detect its drive current value, receive sensor sent alarm Signal, send data and other functions.
The MCU receives the entered code and compares it with the password stored in the EEPROM. If the password is correct, the electromagnetic actuator is unlocked; if the password is incorrect, the operator is allowed to re-enter the password, up to three times; if three times If it is not correct, the MCU will alarm the intelligent monitor through the communication line. The single-chip microcomputer sends the unlocking operation and the driving current value of the electromagnetic actuator as the status information to the intelligent monitor at this time, and also sends the alarm information received from the sensor interface to the intelligent monitor as the basis of the intelligent analysis.
Electronic lock price quotes
Compared with mechanical locks, electronic locks have the characteristics of convenient operation and good confidentiality, and electronic locks have become a symbol of people's status. Correspondingly, the price of electronic locks is much more expensive than mechanical locks.
According to the survey of products on the market, the price of electronic locks varies greatly depending on the place of use.
The price of hotel door locks and hotel locks is relatively simple because of the functional requirements for locks. The price is about 160-450 yuan per piece.
The electronic locks used in the office are mainly password locks. The price of electronic locks for offices is about 530 to 1200 yuan per person. If there is an attendance function, the price of electronic locks is about 600-1200 yuan.
Household electronic locks have higher requirements for safety and appearance, and the corresponding home electronics are more expensive.
What is the above principle about the electronic lock? The content of the electronic lock price quote is introduced here. Is there any unclear? I hope to help everyone.
