Description

technical field [0001] The invention belongs to the outdoor real-time monitoring technology of a power system, and relates to a monitoring system for an outdoor cabinet of a power system. Background technique [0002] At present, a large number of high-voltage power distribution rooms, power distribution cabinets, ring network cabinets and other equipment in the power system are operating in outdoor unattended places, often due to unpredictable factors such as flooding, fires caused by high temperatures inside the equipment, or human damage. The loss of power supply department and users. At the same time, due to the large number of outdoor computer rooms and cabinets, the installation locations are scattered and messy, and the doors of the computer rooms and cabinets still use ordinary keys. When performing related maintenance, maintenance personnel often have to carry a large number of keys, and also need to remember clearly. The key corresponding to each cabinet, which gr...
