Electronic lock with function of automatically generating password and control method thereof

Abstract

The invention relates to an electronic lock with a function of automatically generating a password and a control method thereof. The electronic lock comprises a controller module, a keyboard input and display module, a password querier module and a lock mechanism module, wherein a batch password generating unit and a password comparing and managing unit are arranged in the controller module; one signal input / output end of the controller module is connected with one signal input / output end of the keyboard input and display module; one of signal output ends of the controller module is connected with a signal input end of the password querier module; and the other one of the signal output ends of the controller module is connected with a signal input end of the lock mechanism module. According to the invention, a mass of user passwords can be automatically generated; only one user password is effective in the same time and automatically invalid after being used and the next user password is activated; even if the process that a user inputs the password is peeped by others, the electronic lock cannot be opened through the peeped password by others; the risk of leaking the password is avoided; and therefore, the electronic lock has the characteristics of high safety.
