Description
Technical field
The present invention relates to lock technology fields, more particularly, to a kind of real-time update realizing password, safety it is good and
From a group intelligent cipher lock system and method for management.
Background technology
Electronic lock has merged the multiple technologies such as electronic technology, IC design, the communication technology and encryption technology, is modern
The important development direction of social lockset.
There are inconveniences for traditional coded lock, especially same that coded lock or a personal use is more in more personal uses
In the case of coded lock, if password is set as identical, safety is poor, if password is set as different, remembers
It is all too complicated with operating, in addition easily stolen secret information in operation by other people.
Infrared remote control is a kind of wireless, non-contact observation and control technology, be most popular communication at present and remote control means it
One, have many advantages, such as strong antijamming capability, it is information transmitting, at low cost, low in energy consumption and easy to implement, by infrared technique and list
The intelligent cipher lock that piece machine is combined is widely applied.
The cost of infrared remote controlled code lock system is suitable with contact coding lock system, and can carry out closely distant
