Abstract

The invention relates to the field of aircraft, in particular to an unmanned aerial vehicle dual-redundancy system control method. The system comprises a power supply module, a video transmission module, a power module, a compass module and a flight controller, the power supply module adopts a double-battery parallel connection mode to supply power, the video transmission module adopts a double-path image transmission unit, the power module adopts a coaxial double-propeller rotor wing structure, the compass module adopts an internal compass and an external compass, and the video transmission module, the power module and the compass module are all connected with the flight controller. According to the unmanned aerial vehicle, dual-redundancy setting is adopted on the power supply module, dual-redundancy setting is adopted on the video transmission module, the power module and the compass module, the probability of shutdown or crash after the unmanned aerial vehicle breaks down is greatly reduced, and it is guaranteed that the unmanned aerial vehicle can smoothly complete work in some special and key fields.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a control method for a dual redundant system of an unmanned aerial vehicle. Background technique [0002] UAVs are easily affected by various factors during the flight movement, such as weather factors, wind factors, electromagnetic factors, flight environment factors and human factors, which make the UAV prone to failure. The failure of the UAV will delay the work, and cause the crash of the UAV, resulting in certain property losses. [0003] At present, there is a patent titled "A Dual-redundant Aviation Power Supply and Its Power Supply Mode", with the application number 201110258227.2, which discloses a dual-redundancy aviation power supply and its power supply mode, which is realized on the power supply module of the drone. The dual-redundant design ensures that as long as two batteries do not fail at the same time, the power supply module can provide stable and continuous power to ...
