Multi-rotor unmanned aerial vehicle flight control system

Abstract

The present invention relates to a multi-rotor unmanned aerial vehicle flight control system. The system comprises a master control module, an automatic navigation module, an electric quantity monitoring module, a stroke measurement module, a remote control module, a wind speed measurement module, a wind direction measurement module, an execution mechanism drive module, a power supply module and afirst GPRS communication module. The automatic navigation module, the wind speed measurement module, the wind direction measurement module, the stroke measurement module and the execution mechanism drive module are connected with the master control module, the electric quantity monitoring module is connected with the master control module and the power supply module, and the remote control moduleis internally provided with a first GPS location unit and a second GPRS communication unit. The multi-rotor unmanned aerial vehicle flight control system determines whether an unmanned aerial vehiclehas enough electric quantity for safe return flight or not in real time, and when the monitored data information reaches a return flight critical point, the master control module controls the execution mechanism drive module to allow the unmanned aerial vehicle to return flight.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a multi-rotor unmanned aerial vehicle flight control system. Background technique [0002] Multi-rotor UAV is also called multi-axis aircraft. It is controlled by three or more independent power systems. It has a simple structure and can be controlled by coordinating the speed between the motors. The attitude of the aircraft is high. It has a very broad field of use and research value. [0003] At present, multi-rotor UAVs do not have the function of automatic return when the battery is low. Most of them are judged and controlled by people themselves, and the accuracy is low. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a multi-rotor UAV flight control system to overcome the deficiencies in the above-mentioned prior art. [0005] The technical solution of the present invention to solve the above ...
