The invention discloses an anti-misoperation lockset and a control method thereof. The anti-misoperation lockset comprises a lock body, a lock hook and a lock core component, wherein the lock core component comprises a locking pin, a first elastic component and an unblocking pin. The anti-misoperation lockset further comprises an electric locking mechanism and a built-in circuit, wherein the electric locking mechanism is arranged in the lock body and is used for limiting or releasing the locking pin or the unblocking pin; the built-in circuit is arranged in the lock body, is connected with the electric locking mechanism and is used for controlling the action of the electric locking mechanism; the built-in circuit comprises a plurality of electrical contacts arranged at the surface of the lock body, and is electrically connected with an external circuit through the electrical contacts; and the external circuit supplies power to the built-in circuit and carries out two-way communication with the built-in circuit through the electrical contacts. The safety of the anti-misoperation lockset is improved, and the reliability of equipment locking is guaranteed. In addition, after the anti-misoperation lockset is applied to an electric power anti-misoperation safety system, the overall performance of the electric power anti-misoperation safety system can be improved.
Description
technical field [0001] The invention relates to locks, in particular to a misoperation-preventing lock and a control method thereof. Background technique [0002] The safe and reliable operation of the power system involves the normal power consumption of tens of millions of users. If power equipment fails, it will directly affect the normal life and production of residents and industrial users. The reliability of the anti-mistake lock installed on the anti-mistake device is directly related to whether the equipment can operate safely. [0003] figure 1 Shown is the structural diagram of the padlock in the prior art. As shown in the figure, the locking pin 204 is inserted into the groove of the padlock hook 201 to prevent the locking hook 201 from bouncing off. When the unlocking pin 205 is rotated, the unlocking pin 205 drives the locking pin 204 moves until the lock hook bounces off under the action of spring 206, thereby realizing the unlocking of the lockset. This kin...
