In this patent, the lock not only has the relevant locking components of the traditional mechanical lock, but also has devices such as a code reader, a lock controller, a signal transceiver and a solenoid valve. The solenoid valve is controlled and acted by the lock controller, and the valve core of the solenoid valve and the lock hole on the lock core can be inserted and matched. In this way, when the lock controller sends a control signal to the solenoid valve, the solenoid valve core will be pulled out from the lock hole and retracted into the solenoid valve cavity, so as to realize the unlocking function of the lock core, that is, the lock core is driven by the correct key rod. The lock can be opened. In the natural state, that is, when the lock controller does not send control information to the solenoid valve, the valve core of the solenoid valve is automatically inserted into the lock hole of the lock core. At this time, the lock core is locked, even if the corresponding key lever is inserted. The lock cannot be turned, i.e. cannot be opened. Therefore, the lock of the present patent has dual anti-theft functions, that is, the key lever is one anti-theft method, and the lock controller is the second anti-theft method.

This patent also includes a key that can open the above-mentioned lock, mainly including a key housing, a key rod that is inserted and fitted with the lock cylinder is fixed on the key housing, and a code reader corresponding to the code reader is installed at the connection between the key rod and the key housing. The RFID head for communication, the RFID head is set side by side with the key lever. Therefore, when the key rod is inserted into the lock cylinder of the lock, the RFID head is aligned with the code reader on the lock case, and information can be transmitted to the code reader. A key controller electrically connected with the RFID head is installed in the key housing. The key controller is the core component of the key and controls the work of the RFID head. The signal terminal of the key controller is electrically connected with a key signal transceiver, and its main function is to communicate with the key switchboard. The output end of the key controller is electrically connected with an alarm, and when the triggering condition is reached, the key controller will control the alarm to give an alarm, so as to remind the operator. A display screen electrically connected to the key controller is installed on the key housing, and the main function is to transmit the two-dimensional code to the operator. In this patent, the two-dimensional code used to open the door is different each time, so displaying the two-dimensional code on the display screen is not only simple and convenient, but also has the anti-theft function to prevent reuse.
