[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3The utility model provides a technical solution: an intelligent passive five-protection metering lead sealing cabinet, which is mainly composed of a five-protection metering lead sealing cabinet body 1, a cabinet door 2, a passive electromagnetic lock 3, an intelligent key 4 and a mobile terminal 5. The five-protection metering lead sealing cabinet body 1 is the supporting structure of the entire lead sealing cabinet. Its design meets the safety protection requirements of power equipment, has sufficient strength and rigidity, and can withstand certain external force impacts. The main body 1 is provided with space for storing power equipment and is equipped with necessary fixing devices to ensure the stability of the equipment during transportation and storage. The cabinet door 2 is connected to the five-protection metering lead sealing cabinet body 1 by hinges or other connection methods and can be easily opened and closed. The outer surface of the cabinet door 2 is flat and smooth, and is easy to clean and maintain. On the inner side of the cabinet door 2, a passive electromagnetic lock 3 is installed to realize the locking and unlocking functions of the cabinet door;

[0021] The passive electromagnetic lock 3 is an electromagnetic lock that can be locked and unlocked without an external power source. Its operating principle is as follows: when the smart key 4 approaches and activates the passive electromagnetic lock 3, the smart key 4's built-in power supply 41 provides power to the passive electromagnetic lock 3 through electromagnetic induction, generating a magnetic force to lock or unlock the cabinet door 2. An RFID tag 31 is mounted on the surface of the passive electromagnetic lock 3. This tag stores unique identification information related to the lock and is used for authentication and information exchange with the smart key 4.

[0022] The smart key 4 is a key component, housing a power supply 41 and an RFID reader 42. The power supply 41 provides the necessary electrical energy to ensure proper operation. The RFID reader 42 reads the information stored in the RFID tag 31 attached to the passive electromagnetic lock 3 and performs authentication and unlocking operations based on the information. The smart key 4 also features wireless communication, enabling wireless connection and data exchange with the mobile terminal 5.

[0023] The mobile terminal 5 is a portable device, such as a smartphone or tablet computer. It has a built-in wireless module 51 (such as a Wi-Fi module or a Bluetooth module) for establishing a communication connection with the smart key 4. Through the mobile terminal 5, the user can conveniently view and manage information such as the usage history of the smart key 4 and the lock status, enabling remote monitoring and management.

[0024] To lock the five-protection metering and lead-sealing cabinet, the user first closes the cabinet door 2 and places the smart key 4 near the passive electromagnetic lock 3. The RFID reader 42 in the smart key 4 reads the information from the RFID tag 31 on the surface of the passive electromagnetic lock 3 and performs identity verification. Once the verification is successful, the power supply 41 built into the smart key 4 supplies power to the passive electromagnetic lock 3 via electromagnetic induction, causing it to generate magnetic force and lock the cabinet door 2.

[0025] To open the five-protection sealed lead cabinet, the user again places the smart key 4 near the passive electromagnetic lock 3. The RFID reader 42 in the smart key 4 reads the information in the RFID tag 31 again and performs identity verification. Once verified, the smart key 4 sends an unlock signal to the passive electromagnetic lock 3, causing it to lose its magnetic force and unlock the cabinet door 2. The user can now conveniently open the cabinet door 2 and remove or insert electrical equipment.

[0026] The smart key 4 can wirelessly connect to and exchange data with the mobile terminal 5. Through the application or browser interface on the mobile terminal 5, the user can view the usage history of the smart key 4, the lock status, and other information in real time. Furthermore, the user can remotely manage and control the smart key 4 through the mobile terminal 5, such as setting permissions and changing passwords.
