when the fingerprints are matched, the controller 21 controls the first electric push rod 15 to extend out, so as to drive the locking pin 16 to be inserted into the locking notch 121; then, the lock is closed after the hand is loosened;
when the fingerprints do not match, the controller 21 controls the first electric putter 15 not to be operated.
Example 3:
on the basis of embodiment 2, the control system 2 further includes an electromagnetic induction module 24 for inducing current in the locked device;
a locking assembly capable of fixing the locking pin 16 in place is arranged in the lock body 11;
the electromagnetic induction module 24 is connected with the controller 21, and the controller 21 is connected with the locking assembly.
In the inspection and maintenance operation, the equipment for inspection and maintenance needs to be ensured to be completely powered off so as to ensure the safety of the inspection and maintenance process. However, in actual maintenance work, the power supply is often forgotten to be cut off or is accidentally turned on, and at this time, if the lock is opened or closed for maintenance work, potential safety hazards exist. And this problem can be solved in setting up of tool to lock in this application, specifically as follows:
when the equipment that locks does not cut off the power or the power is opened by accident, the inside electric current that can exist of equipment to form electromagnetic signal, this application tool to lock electromagnetic induction module 24 can sense the electromagnetic signal that this electric current produced, and give controller 21 with this signal transmission, and controller 21 control locking assembly fixes locking round pin 16 at the normal position, even the fingerprint comparison succeeds this moment, the tool to lock also can't be unblock, can't open, close the action of locking. At this moment, the operator needs to check the power supply and confirms that the power supply is closed, and when the electromagnetic induction module 24 cannot induce an electromagnetic signal, the lock can be unlocked, and the operator can open or close the lock through fingerprints.
Therefore, the lockset can detect whether current exists in the locked equipment through the electromagnetic induction module 24, ensure that the power supply of the locked equipment is thoroughly cut off in the maintenance process, and effectively avoid the condition that the power supply is not turned off or the power supply is accidentally turned on in the maintenance process, thereby avoiding accidents caused by accidental turning on of the equipment in the maintenance process.

The intelligent lock for maintenance operation in embodiment 3 has the following specific implementation modes of unlocking or locking:
(1) unlocking lock
a. The electromagnetic induction module 24 induces current
When the power supply of the locked equipment is proved to be not cut off, the controller 21 controls the second electric push rod 110 to extend, so that the upper locking hoop 1101 and the lower locking hoop 1101 are tightly held on the locking pin 16, and the locking pin 16 is fixed at the locking position;
