The key head 201 is not detected by the first hall sensor 31, and the mechanical lock 100 is not detected by the second hall sensor 32.

As shown in fig. 19, when closing a gate with a mechanical lock 100 installed, the operation is as follows:

first, the handheld identification device 202 is connected to the key head 201 left on the mechanical lock 100, the first hall sensor 31 in the sensing unit 204 detects the second magnet 2013 in the key head 201, the second hall sensor 32 detects the first magnet 103 on the mechanical lock 100, and the display 8 shows that the smart key 200 is successfully assembled. The pin 41 of the solenoid valve 4 is in an extended state and prevents the key head 201 from rotating. The position of the second identity reading antenna 22 corresponds to the identity tag 104, the second identity reading antenna 22 detects the identity tag data and sends the identity tag data to the host, the host counts and analyzes the identity tag data and confirms that the handheld identification piece 202 is matched with the mechanical lock 100 and the key head 201 left on the mechanical lock 100, the pin 41 of the electromagnetic valve 4 retracts, and the handheld identification piece 202 can drive the key head 201 to rotate.

Then, the smart key 200 is rotated counterclockwise, during the rotation, the locking hook 51 hooks the locking portion 106, and the second identity reading antenna 22 is far away from the identity tag 104; when the locking hook 51 is separated from the locking part 106, the key head 201 rotates to a free position, the first identity reading antenna 21 corresponds to the identity tag 104 on the locking cover 102 in position and detects identity tag data, the identity tag data is sent to the host, the host analyzes the identity tag information and confirms that the key head 201 reaches the free position, the mechanical lock 100 is closed, and the gate is closed.

Finally, the smart key 200, including the key head 201 and the handheld identification member 202, is pulled out, and the smart key 200 is separated from the mechanical lock 100.

In addition, in all the above operation processes, if the information mismatch between the key head 201, the mechanical lock 100, and the handheld identifier 202 occurs, the LED display lamp 14 may display a red light signal to prompt the operator to perform the matching again, all the information may be displayed in the display screen 8, the prompt information in the display screen 8 includes information that the key head 201 is successfully connected with the handheld identifier 202, the key head 201 is successfully inserted into the mechanical lock 100, the key head 201 is separated from the handheld identifier 202, and the like, and as for the operation principle of the program information, the operation principle is not in the protection scope of the present application, and is not described herein again.

In particular, a restart button is provided on the key head 201, enabling to restart the program of the intelligent interlocking module. Particularly, a buzzer and a voice module are arranged in the handheld identification piece 202, and information such as the position state detected by the intelligent key 200 is prompted and broadcasted.

It will be appreciated by those of ordinary skill in the art that in the embodiments described above, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the claims of the present application can be basically implemented without these technical details and various changes and modifications based on the above-described embodiments. Accordingly, in actual practice, various changes in form and detail may be made to the above-described embodiments without departing from the spirit and scope of the invention.
