Unmanned aerial vehicle autonomous grid line patrol system

Abstract

The invention relates to an unmanned aerial vehicle (UAV) autonomous grid line patrol system which comprises more than one UAVs for line patrol, more than one land fields arranged on grid towers, and a ground control center for control and analysis. Each of the landing fields comprises a support panel for bearing a UAV, a rain cover arranged above the support panel, and a charging module, an environmental monitoring module and a wireless communication module arranged on the support panel. The charging module, the environmental monitoring module and the wireless communication module are electrically connected to a control unit arranged on the support panel. The control unit communicates with the UAV and the ground control center through the wireless communication module. The system has the advantages that through the landing fields arranged on the grid towers, a guarantee is provided for the cruising of the UAV line patrol, and the cost of UAV return and stop is saved.

Description

technical field [0001] The invention relates to the technical fields of unmanned aerial vehicle technology and power grid line inspection, in particular to an autonomous power grid line inspection system for unmanned aerial vehicles. Background technique [0002] In the power system, overhead transmission lines cover a wide area and pass through complex terrain, and power lines and towers are exposed to harsh natural environments for a long time. In order to ensure the safety and stability of the power system, grasp the operation status of the transmission line and eliminate potential safety hazards in the line in time, the power sector spends huge manpower and material resources on line inspection every year. At present, manual inspection is the most widely used in the inspection of transmission lines, and manned helicopters are required to be dispatched for inspection in some terrain areas. Manual regular inspections not only have high work intensity, poor working environ...

AI Technical Summary

Problems solved by technology

The above studies have achieved beneficial effects to a certain extent, but there are still the following deficiencies: the endurance of the UAV is poor, and it is impossible to patrol the entire power transmission line, resulting in a limited range of patrol lines. After the task is over, you have to return to the base station to charge, which limits the efficiency of the drone's line inspection; it is impossible to monitor the surrounding environment of the tower in real time, and it is impossible to grasp the status of the tower in time; under the existing technology, the communication range of the drone is limited , the ground mobile station is required to follow the UAV to carry out line inspection work. In the large-scale line inspection task, it is also necessary to add a mobile communication relay station, which increases the cost of manpower and material resources.
