The electronic code lock is a kind of electronic product that controls the circuit or the chip work (access control system) through the password input to control the closing of the mechanical switch to complete the unlocking and locking task.
Electronic lock in the field of security technology to prevent the anti-theft alarm function of the electronic code lock instead of the traditional mechanical lock, to overcome the mechanical password lock less password, the poor performance of the shortcomings of the security, whether in the technical or technical performance On the big step forward.
The so-called smart lock, is the electronic technology, integrated circuit design, a large number of electronic components, combined with a variety of innovative identification technology (including computer network technology, built-in software card, network alarm, lock body mechanical design) and other integrated products The
The study of electronic code locks began in the 1930s and has been applied in some special places. The amount of key (amount of encryption) of the electronic lock can be used in conjunction with a mechanical lock, and it is possible to avoid a security risk due to the imitation of the key. Electronic lock just remember a group of passwords, without carrying a metal key, eliminating the people carrying the metal keys of trouble, which is more and more people appreciate.
After the 1980s, with the emergence of electronic lock special integrated circuits, electronic lock size reduction, increased reliability, higher cost, is suitable for use in the high security requirements of the occasion, and the need to provide power to provide energy, the use of But also confined to a certain range, it is difficult to popularize, so its research has been no significant progress.
By the 1990s, the development of microelectronics technology and the development of communication technology in the United States, Italy, Germany, Japan, Canada, Korea and China, Taiwan, Hong Kong and other places provided technical support for the password lock, thus pushing the password lock to the actual The stage of the application.
To the early 21st century, in Western countries, electronic code lock technology is relatively advanced, full range, electronic code lock has been widely used in intelligent access control system, making it more secure and more reliable to achieve the door management.
China in the early 90s began a preliminary exploration of the password lock. So far, with the development of electronic technology and information technology, electronic code lock technology has been developed very mature. From the technical level of the early 20th century and the degree of market recognition, the most widely used is the keyboard electronic code lock, the product is mainly used in safe, safe and vault, and some used in safe and armored vehicles. In other areas of technology there are remote control electronic password lock and card-type password lock and so on.
Because of this' self-sustaining, carry 'key' highlights' advantages, so this lock quickly passed the performance is not stable, expensive initial period, becoming more and more practical, more and more 'features ', By the people generally welcome. Today, the rapid development of biometric technology, in addition to price factors and size factors on the popularity of restrictions, the biometric electronic anti-theft lock in the financial industry prospects are generally optimistic.
Because digital, character, graphic image, human biology and time and other elements can be the key electronic information, the combination of these information can make electronic anti-theft lock to obtain a high degree of confidentiality. Combined use of information can also make electronic anti-theft lock access to the possibility of infinite expansion, so that product diversification.
At the beginning of the 21st century. Contact card technology is mature, the price is low, the application is more extensive; non-contact card using hidden, convenient, great come from behind the trend. Storage of information is large card advantage, it not only as a key, but also load a number of personal information, especially for the financial industry focus on 'check out the body' industry characteristics, and a multi-purpose (such as entry, unlock, storage, Etc.) to bring the convenience of cardholders. Use this type of electronic anti-theft lock, need to carefully custody card (ie key), especially lost must be canceled as soon as possible card authorization.
At the beginning of the 21st century, in the western developed countries, the password lock technology is relatively advanced, the full range, the electronic code lock has been widely used in the intelligent access control system, through a variety of more secure, reliable technology to achieve the door management. In China, the overall level of password lock is still in the international 70 years or so, the cost of electronic code lock is still high, the market is still key electronic locks, key and card key electronic lock has introduced the international advanced level. Many domestic enterprises have also introduced the world's advanced technology, development prospects are very impressive.
Smart lock to replace the mechanical lock is a necessary trend, we have reason to believe that the smart lock will be its unique technical advantages, leading the Chinese lock industry to get better development, so that more people more assured in more occasions , Will make our future more secure. "Home of the" APP open to lock the door service with a preferential price will be smart lock to your side, guard your home safe.
