[0062] In order to make the purpose, technical scheme and advantages of the application more clear, the application will be further described in detail below with reference to the drawings.
[0063] As Figure 1 shown, the front structure schematic view of one embodiment of the intelligent key cabinet for managing the switch body maintenance special key provided by the application is shown; in combination with Figures 2 to 8 shown, in the embodiment, the intelligent key cabinet at least includes:
[0064] The shell, the front of which is provided with:
[0065] A plurality of key fobs 1 for taking keys;
[0066] The touch display screen 2 is used for realizing man-machine interaction;
[0067] The camera 3 is used for taking pictures of the key requester;
[0068] The fingerprint collector 4 is used for collecting the fingerprint of the requester;
[0069] At least a main controller 5 is arranged inside the shell, and the main controller is electrically connected with the above-mentioned components, and at least includes:
[0070] The verification unit 50 is used for verifying the requester after receiving the taking instruction of the corresponding key, and the key includes the unlocking or interlocking key;
[0071] In a specific example, the verification unit 50 verifies the user using a password, fingerprint, or facial recognition. If the user's information is found in the authorized user information, the verification is deemed successful.
[0072] The key retrieval condition detection unit 51 is used to detect whether the current state of the switch body corresponding to the key meets the key retrieval condition.
[0073] In a specific example, the access condition detection unit 51 is further configured to:
[0074] Detect the requested key type and detect the position status of the knife switches on both sides of the switch corresponding to that key type;
[0075] Determine whether the knife switches on both sides of the switch are in the open position. If they are in the open position, then the key retrieval condition is met. Figure 7 and Figure 8 The diagram illustrates the connection diagram of the two disconnectors on both sides of the 500kV equipment involved in this invention, and the diagram showing the conditions for retrieving the maintenance key for the switch body. Reference numerals 5011, 5012, and 5013 all represent a 500kV switchgear, with a disconnector connected to each end. For example, switchgear 5011 has disconnectors 50111 and 50112 connected to its two ends. This intelligent key box is inserted into the disconnector positions on both sides of the 500kV switch, ensuring that the unlocking / interlocking key for the corresponding switch can only be retrieved when the disconnectors on both sides are in the open position. This prevents misoperation by operators during normal operation.
[0076] The latch opening control unit 52 is used to control the latch of the key buckle to open after verification and the key retrieval conditions are met; after the key on the latch is removed, it controls the spring under the key buckle to release the pressure and lock the key buckle.
[0077] The latch closing processing unit 53 is used to release the lower link of the key fob and open the upper link latch after detecting that the key has been returned, so that the key fob will automatically close.
[0078] The information interaction unit 54 is used to receive authorized personnel information from the backend; and to record key usage information and upload it to the backend or notify relevant personnel.
[0079] like Figure 4 As shown, in a specific example, the information interaction unit 54 further includes:
