Description

technical field [0001] The invention belongs to the field of transformer substation equipment patrol inspection, and in particular relates to a flight safety system of a transformer substation patrol drone. Background technique [0002] Substation equipment inspection is a basic work to ensure the safe operation of substations and improve the reliability of power supply. With the improvement of substation automation level and the popularization of unattended operation, the reliability of substation equipment operation is facing more severe tests. Substation inspection is subject to greater emphasis. Traditional manual inspections can no longer meet the requirements of safe operation of modern substations. With the rapid development and maturity of drone technology, navigation technology and wireless communication technology in recent years, many power companies at home and abroad have begun to try to use drones for power system inspections. In the current application proce...

Problems solved by technology

[0003] However, the electromagnetic environment of the substation is complex. When the UAV performs inspection tasks in the substation, its flight control and communication systems will easily cause the UAV to lose control when it encounters strong electromagnetic interference.

Due to the dense equipment in the substation, when the UAV has a flight accident in the substation, it is very likely to cause damage to important equipment in the substation, and then endanger the safe operation of the substation. Therefore, when flying in the substation, the positioning accuracy of the UAV should be improved. It is especially important for the safe flight of UAVs to plan the optimal flight route and adjust it in real time in response to environmental changes.
