[0002] Power distribution equipment is a general term for equipment such as high-voltage switch cabinets, generators, transformers, power lines, circuit breakers, low-voltage switch cabinets, distribution boards, switch boxes, and control boxes in the power system.

[0003] In vision and thermal imaging technologies, switch cabinets are required, but if the temperature inside the switch cabinet is too high, it is likely to cause damage. Generally, temperature sensors are used to monitor the temperature inside the switch cabinet. However, existing switch cabinets generally have multiple layers, and it is difficult for temperature sensors to monitor the temperature of equipment on different layers, resulting in low practicability. In addition, existing temperature sensors are not convenient for disassembly. Therefore, we propose an on-line temperature monitoring method for power distribution equipment using vision and thermal imaging technologies to solve the above problems. Summary of the Invention
