Dynamic password lock system and method for self-help network management

The invention discloses a dynamic password lock system and a method for self-help network management. Due to adoption of the method, opening, closure, control on opening rejection and information record of a safe case door of self-help equipment, namely, an application terminal, are achieved, and an unlocking password is transmitted to the self-help equipment to display from a servo through the conventional network of the self-help equipment, then a person can input the password on a password lock to open the safe case door lock. The dynamic password lock system consists of a lock, a lock inner circuit unit and an information input and output device. The dynamic password lock system has the advantages that in addition that fixed initialization data and variable operation data are input into an algorithm input terminal, dynamic time data are also introduced, a dynamic password is obtained for identity verification, and moreover the dynamic password is only valid within certain time, so that the security is greatly improved, the password does not need to be changed at regular time, and high practical values and practical significance are achieved.
