In order to ensure the normal use of the power distribution cabinets and prevent potential faults, a regular manual inspection operation and maintenance mode is generally adopted conventionally, and the mode is generally used for uniformly inspecting, testing and maintaining all the power distribution cabinets based on a fixed time period, wherein the content comprises appearance inspection, temperature measurement, fastener state, instrument reading, environmental conditions and the like. However, in an actual application scene, the installation positions of the power distribution cabinets are various, and the actual environmental conditions in which the power distribution cabinets are located have significant differences.
