Abstract
The invention relates to the electrical technical field, in particular to an intelligent locking system. The intelligent locking system comprises a clamping-connection piece, a lock body, a linkage assembly, a drive assembly, a position sensor, a control unit and an electronic key, wherein the linkage assembly, the drive assembly, the position sensor, the control unit and the electronic key are arranged in the lock body. The position sensor is arranged beside the drive assembly so as to detect the movement position of a movement part of the drive assembly, then whether the lock body is in a locked state or not can be obtained, the control unit then can accurately control the drive assembly, and accurate control over the unlocking state and the locking state of the locking system is achieved. Whether a locking device is in the locked state or the unlocking state can be received through a microprocessor; and when the locking device is in the unlocked state, if a worker pulls out the electronic key by accident, the microprocessor makes a judgment and gives out an alarm message to an alarm unit, and accordingly misoperation is avoided. Meanwhile, when the lock body needs to be unlocked, a person inserts the electronic key in the lock body, and the person can pull the electronic key out of the lock body when the lock body is locked. The locking system is electrically neutral, so that passive locking is achieved, power consumption is low, and maintenance is convenient.
