Special-purpose unmanned helicopter obstacle-avoidance system for mountain-area electrical network routing inspection and work flow thereof

Abstract

The invention discloses a special-purpose unmanned helicopter obstacle-avoidance system for mountain-area electrical network routing inspection and a work flow thereof. The special-purpose unmanned helicopter evadible system comprises an on-board signal acquisition module and an on-board obstacle-avoidance analysis module in a flight control system. The on-board signal acquisition module comprises a millimeter wave radar ranging sensor. The millimeter wave radar ranging sensor is connected to a signal pre-processing module and is used for transforming analog signals into digital signals, and transmitting the environmental information to the on-board obstacle-avoidance analysis module by a communication port. Corresponding instructions are transmitted to a control computer of the flight control system by the on-board obstacle-avoidance analysis module. Corresponding instructions are transmitted to an unmanned helicopter rudder control system by the control computer of the flight control system. The special-purpose unmanned helicopter obstacle-avoidance system avoids artificial intervention, ensures that the unmanned helicopter with the special-purpose unmanned helicopter obstacle-avoidance system can keep a safe distance to an electric power circuit at any time under complex mountain area terrain conditions, and prevents that the unmanned helicopter crashes the electric power circuit and other barriers because of sharp-edged gust disturbance or GPS errors.

Description

[0001] technical field [0002] The invention relates to a medium-sized special-purpose unmanned helicopter system suitable for patrol inspection of mountainous power grids, in particular to a special-purpose unmanned helicopter obstacle avoidance system suitable for mountainous power grid patrol inspections and its working process. [0003] Background technique [0004] With the development of the power system, the transmission line is getting longer and longer, and the voltage level is getting higher and higher. At present, there are nearly 900,000 kilometers of power lines of 110kV and above in my country. Line inspection operations are carried out many times a year, and the workload is huge. [0005] At present, the inspection methods adopted in my country are mainly manual inspection and manned helicopter inspection. Manual inspection is the inspection of power line inspection personnel walking along the line. The inspection method is mainly to check th...

Problems solved by technology

The use of manned helicopter inspection technology and methods has problems such as expensive helicopters and their maintenance costs and personnel safety.

Due to the limitations of testing instrument technology, the flight speed of the manned aircraft cannot be too fast and the altitude cannot be too high, so a slight error in the flight of the manned aircraft may cause serious consequences of aircraft crash and death, and it is also very likely to cause serious damage to the aircraft. Disastrous consequences for power grids

Although some drone inspection systems have been developed at present, the current drone control system does not have an obstacle avoidance system. The drone must observe the flight status and position of the drone in real time during the flight. Obstacles must be manually operated in time to avoid obstacles, which not only increases the workload of the operator, but also poses a great safety hazard
