Intelligent lock (Intelligent Lock) is different from the traditional mechanical lock, in the user identification, security, management of the more intelligent locks. Intelligent lock is the executive part of door lock in access control system.
Now the intelligent lock is different from the previous "first open scan" manner, scanning is very simple, from top to bottom above the finger on the scanner can scan, without the finger on the scan, the scanning mode and reduce residual fingerprint, greatly reduce the possibility of fingerprint is copied, exclusive security.
Chinese name intelligent lock foreign name Intelligent Lock product face recognition lock, fingerprint lock, induction lock feature scanning method is simple and safe

Intelligent lock is different from the traditional mechanical lock, in the user identification, security, management of the more intelligent locks, access control system locks the executive parts.
The intelligent lock is different from the traditional mechanical lock, and it is a compound lock with security, convenience and advanced technology.
The use of non mechanical keys as a mature technology, ID user identification such as fingerprint lock, iris recognition access control (biometrics, high security, there is no loss of damage; but not convenient configuration, high cost) of magnetic card and RF card (non contact, high safety, convenient carry plastic material, configuration, price TM card (low) contact, high security, stainless steel material, the configuration is very convenient to carry, low price) in the following areas: application of more banks, government departments (focus on safety), as well as the hotel, the school dormitory, residents of a small area (to facilitate management)
A. intelligent lock is different from the general mechanical lock, with automatic electronic induction locking system, he will automatically sensing the door is closed, the system will be locked automatically. The intelligent lock can open the door lock through fingerprint, touch screen and card.
B. in the use of fingerprint lock password / fingerprint registration function is not convenient, especially the elderly and children when using individual intelligent lock, can open its unique voice prompt function, allowing users to operate more convenient.
A. general fingerprint password lock has the risk of password leakage. Recently, the intelligent lock also has the function of virtual password technology, namely in the registered password before or after, you can enter any number as a virtual password, effectively prevent the registration of passwords, and open the door.
B. in the ordinary residential security environment, the general door lock handle opening mode can not ensure enough safety performance, can easily drill holes from outside the door, and then turn the handle of the steel wire to open the door. Many intelligent locks have patented technical support, in the interior of the handle settings to increase the safety handle button, you need to hold down the safety handle button, rotating handle door to open, bring more secure use environment. At the same time, according to the user's needs, through simple operation, this function can be selectively set. )
C. the latest smart lock, palm touch screen will automatically display, 3 minutes will automatically lock. The password is set, the door is opened or closed and the number of registration card or password, battery replacement and tips, the lock tongue blocking warning, the situation encountered low voltage, screen with display, intelligent intelligent control.
Recently, the intelligent lock is different from the previous "first open scan" manner, scanning is very simple, from top to bottom above the finger on the scanner can scan, without the finger on the scan, the scanning mode and reduce residual fingerprint, greatly reduce the possibility of fingerprint is copied, exclusive security.
The traditional mechanical lock has no special concern for its appearance. The intelligent lock is not only suitable for people's taste from the appearance design, but also creates an intelligent lock like the apple. Intelligent locks have been listed on the market quietly.
Intelligent lock built-in embedded processor and intelligent monitoring system, has the ability to interact with each other at any time with the tenant, you can actively report the day of the TV visitors. On the other hand, visitors can even remotely control the smart door lock for guests to open the door.

In the security field, with a mechanical cipher anti-theft alarm function of electronic locks instead of the traditional lock, overcomes the less mechanical lock password, poor safety performance, the lock in both technique and performance is greatly improved. With the development of large scale integrated circuit technology, especially the advent of the microcontroller, the microprocessor with intelligent locks it has the electronic password lock function, but also the introduction of intelligent management, expert analysis system and other functions, so that the lock has high safety and reliability, wide application. This paper introduces an intelligent code lock based on 51 series single chip microcomputer. Its working principle, basic function block diagram, key design technique and software working flow are described in detail.
The intelligent password lock system consists of intelligent monitor and electronic lock. The two are placed in different places, and the intelligent monitor supplies the power needed by the electronic lock and receives the alarm information and status information sent by the intelligent monitor. The line multiplexing technology is used to make the power supply and information transmission share a two core cable, which improves the reliability and security of the system.
