The study of electronic code locks began in the 1930s and has long been used in some special places. The electronic lock has a large amount of keys and can be used in conjunction with a mechanical lock, and can avoid the safety hazard caused by the key being copied. The electronic lock only needs to remember a set of passwords, no need to carry a metal key, and it eliminates the trouble of people carrying metal keys, so it is appreciated by more and more people. After the 1980s, with the advent of electronic lock ASICs, the size of electronic locks was reduced, reliability was improved, and the cost was high. It is suitable for use in applications with high safety requirements, and requires power to provide energy. It is still limited to a certain extent and difficult to popularize, so there has been no significant progress in its research.
In the 1990s, advances in microelectronics and the development of communication technologies in the United States, Italy, Germany, Japan, Canada, South Korea, and China's Taiwan and Hong Kong provided technical support for password locks, thereby pushing password locks into practice. The stage of application. At the beginning of the 21st century, in the western countries, the electronic code lock technology is relatively advanced and complete in variety, and the electronic code lock has been widely used in the intelligent access control system, making it safer and more reliable to realize the management of the door.
At the beginning of the 21st century, in the western developed countries, the password lock technology is relatively advanced and complete in variety. The electronic code lock has been widely used in the intelligent access control system to realize the door management through a variety of safer and more reliable technologies. It is an inevitable trend to replace the mechanical lock with a smart lock. We have reason to believe that the smart lock will lead the Chinese lock industry to develop better with its unique technological advantages, so that more people can use it more confidently. It will also make our future safer.
