Flight controller for civil small UAV (Unmanned Aerial Vehicle)

Abstract

The invention provides a flight controller for a civil small UAV (Unmanned Aerial Vehicle). The flight controller comprises a flight control microprocessor, a GPS module, a steering engine driving module, a sensor, a data storing module, a power supply and a ground measuring and control module which form a digital control system in which the resource is unified to be dispatched and distributed and all parts coordinately work. According to the flight controller for the civil small UAV, a hardware system design scheme of the small UAV using an STM32F103RE microcontroller as a core is proposed according to the requirements on small size, light weight, simple structure and high reliability of the civil UAV; the overall scheme design of the system and the main functional modules are described in details; the feasibility and reliability of the design scheme are verified through the flight experiment on a small fixed-wing UAV; in addition, the flight controller is fine in design, low in cost, high in reliability, and suitable for mass production and use.

Description

technical field [0001] The invention relates to an unmanned flight control system, in particular to a flight controller based on a small civilian unmanned aerial vehicle. Background technique [0002] UAV is a kind of unmanned aircraft controlled by radio remote control or controlled by its own program. UAVs not only play an important role in modern high-tech military warfare, but also have broad market and application prospects in the civilian field. Civil UAVs can be used in aerial photography, meteorological detection, survey and mapping, environmental research, nuclear radiation detection, disaster monitoring and rescue, power line inspection and so on. With the expansion of my country's low-altitude open pilot area, the application prospects of drones are becoming more and more optimistic. [0003] The unmanned flight control system is the core of the unmanned aerial vehicle system, responsible for the control of the entire flight process of the unmanned aerial vehicl...

AI Technical Summary

Problems solved by technology

[0009] (1) The volume is large, due to the complex functions of the flight control system and many modules, the weight is too large and the cost is high;

[0010] (2) The control circuit is complex and the anti-interference ability is poor, resulting in a decrease in reliability;

[0011] (3) The structure is complex, the possibility of potential failure increases, and there are many devices in the system, which makes the power consumption of the entire system higher
