Flight control system and method of unmanned aerial vehicle

Abstract

The invention discloses a flight control system and method of an unmanned aerial vehicle. A plurality of sensors for monitoring the running state of an unmanned aerial vehicle and a servo unit are arranged at the unmanned aerial vehicle. The control system is composed of a programmable control unit and a CPU unit; the programmable control unit is electrically connected to the plurality of sensorsand the servo unit and is used for collecting and analyzing data of the plurality of sensors and a remote controller of the unmanned aerial vehicle and sending flight motion data to the servo unit; and the CPU unit is used for operating a flight control algorithm of the unmanned aerial vehicle based on the data analyzed by the programmable control unit and outputting the obtained flight motion data to the programmable control unit. According to the flight control system based on the structure, usage of many external interface chips of the flight control system is reduced; the hardware architecture of the system is simplified; the operation pressure of the CPU is reduced; the flight control system can meet various design tasks; secondary development can be carried out conveniently; and thedesign cost is lowered substantially.

Description

technical field [0001] The present invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle flight control system and method that can be reconfigured as required. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle" ("UAV"), is an unmanned aircraft controlled by radio remote control equipment and its own program control device. UAV is actually a general term for unmanned aerial vehicles. From a technical point of view, it can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airship, unmanned helicopter, unmanned multi-rotor aircraft, unmanned paraglider etc. Compared with manned aircraft, it has the advantages of small size, low cost, convenient use, and low requirements for the flying environment. Drones are often better suited for missions that are too "dumb, dirty or dangerous" than manned aircraft. According to the appli...

Problems solved by technology

[0003] However, the current mainstream UAVs only use a closed flight control system composed of a microprocessor and dedicated peripheral hardware, and its backward flight control system has increasingly become a major obstacle to the development of UAV technology. It can only realize a single flight function. Once the hardware platform is solidified, the system functions will not be further expanded according to actual needs. However, the customer's application requirements are diverse, and the system with a single function cannot adapt to a variety of applications, and the development of multiple varieties and Functional drones will inevitably result in longer design cycles and excessive investment in hardware costs
