[0002] In the power system, as a key node for power conversion and distribution, the safe operation of a substation is of crucial importance. The existing substation monitoring devices have the following deficiencies: on the one hand, traditional monitoring cameras are mostly fixedly installed, only capable of monitoring a single area, unable to achieve flexible adjustment in the horizontal or vertical direction, resulting in limited monitoring range; on the other hand, the existing devices have a relatively single monitoring of the operating status of equipment, making it difficult to comprehensively analyze multiple parameters such as voltage, current, temperature, and gas concentration, and the disassembly process during equipment maintenance is cumbersome, affecting the maintenance efficiency. In addition, for emergencies such as SF6 gas leakage and fire hazards, there is a lack of real-time monitoring and linkage response mechanisms, unable to meet the intelligent monitoring requirements of unmanned substations.
