[0006] 2. The accuracy of hanging signboards cannot be ensured, and there is a risk of misoperation, resulting in equipment damage or personal injury. For example, the person who hangs the signboard hangs the signboard on the wrong equipment cabinet without noticing, and hangs the live equipment as the power-off equipment; for example, the equipment is correctly matched, but the wrong signboard definition is selected, and the slogan of the sign does not correspond, which can easily mislead the operator to make an incorrect operation; or there is a situation where the relevant equipment cabinet is missed, causing the maintenance personnel to accidentally touch the live equipment.

[0007] 3. There is no dynamic confirmation by a third party. All confirmation is done manually to ensure that the sign is selected correctly and that the equipment being hung corresponds correctly. If it is hung incorrectly, there is no mechanism for a third party to remind and correct it. Utility Model Content
