Flight control system of small multi-rotor for power line patrol

Abstract

The invention discloses a flight control system of a small multi-rotor for power line patrol. The flight control system comprises an electronic compass, an angular rate gyro, a height sensor, an accelerometer, a GPS (Global Position System) receiver, a flight control computer and a ground control station. The electronic compass, the angular rate gyro, the height sensor, the accelerometer, the GPS receiver and the flight control computer are arranged on the multi-rotor. The electronic compass, the angular rate gyro, the height sensor, the accelerometer and the GPS receiver are connected with the flight control computer. The ground control station sends remote control commands to the flight control computer. The flight control computer comprises a data input module, an RS232 level switching module, an RS485 level switching module, a data storage SD card module, a smart fusion module, a power supply module, an automatic calling module, a recovery control module, a task device module and a steering engine module. The flight control system of the small multi-rotor for power line patrol has the advantages of improving the control sensitivity of the flying machines and facilitating system updating.

Description

technical field [0001] The invention relates to a flight control system for a small multi-axis aircraft for power line inspection, in particular to a flight control system for a small multi-axis aircraft for power line inspection for high-voltage power transmission lines. Background technique [0002] At present, the inspection work of high-voltage transmission lines mainly relies on manual inspections or fixed-point monitoring by monitoring devices. The method of manual inspection has the following disadvantages: 1) a large number of inspection personnel are required, and additional labor costs are required; 2) inspection is very difficult in bad weather and environments; 3) in environments with poor geographical conditions Among them, it is difficult to implement manual inspection. The fixed-point monitoring method of the monitoring device solves the inspection problem of places that are difficult to manually inspect, but this method can only be monitored at fixed points,...

Problems solved by technology

The method of manual inspection has the following disadvantages: 1) a large number of inspection personnel are required, and additional labor costs are required; 2) inspection is very difficult in bad weather and environments; 3) in environments with poor geographical conditions In the middle, it is difficult to realize manual inspection

However, the control of the small electric cruising multi-axis aircraft in the prior art is relatively complicated. The control systems currently on the market generally adopt an integral module structure, which has poor control sensitivity and is inconvenient for system updates.
