Intelligent lock control method and system

The intelligent lock control method comprises the steps that a work station sends a lock control signal to a computer key according to a lock control requirement, and the computer key generates first verification information; acquiring information of an operator and information of the selected communication interface locking device, setting a first interception position and a first interception length, intercepting and synthesizing a first verification password, outputting the first verification password to a computer key to be matched with the first verification information, and if the matching is successful, setting a second interception position and a second interception length, the second verification password is intercepted and synthesized, the second verification password is matched with the second verification information, if matching succeeds, a third interception position and a third interception length are set, the lock control credential is intercepted and synthesized, the lock control credential i
