Autopilot flight control system

Abstract

The invention relates to an autopilot flight control system. The autopilot flight control system comprises a flight control panel, a radio station, a servo mechanism, a receiver and a remote controller, wherein the radio station is communicated with the flight control panel in a two-way mode on remote control and telemetering, the servo mechanism receives servo control instructions of the flight control panel, the receiver transmits manual control instructions to the flight control panel, and the remote controller transmits remote manual control instructions to the receiver. The flight control panel further comprises a central processing module, a communication module which communicates with the central processing module in a two-way mode, a sensor module which communicates with the central processing module in the two-way mode, and a servo output module which receives instructions of the central processing module, wherein the communication module of the flight control panel receives instructions of the receiver and communicates with the radio station in the two-way mode. The radio station communicates in the two-way mode with a ground control system outside the autopilot flight control system. The servo output module transmits servo information to the servo mechanism. The autopilot flight control system is small in structure, simple and clear in system design, high in computation efficiency and reliability and very good in expansibility and portability.

Description

technical field [0001] The invention belongs to the technical field of automatic control of unmanned aerial vehicles, relates to multi-sensor data acquisition, extended Kalman filtering, self-adaptive servo mechanism control technology, and specifically relates to an automatic driving flight control system. Background technique [0002] UAV flight control system has a history of decades of development in my country, but due to the late start of research and development of UAV in my country, poor foundation, less relevant technical reserves and talent reserves, and foreign restrictions on my country in terms of key technologies, As a result, there is a big gap between my country and Europe, America, Russia and other countries in the research and development of UAV flight control systems. [0003] In terms of application, UAV flight control systems are mainly divided into two categories: military and civilian. At present, research on UAV systems is mainly based on military UAVs...

AI Technical Summary

Problems solved by technology

A number of UAV systems of many units in my country have passed the appraisal of scientific and technological achievements of aerial survey and remote sensing system products based on low-altitude unmanned aerial vehicles organized by the State Bureau of Surveying and Mapping. One of them is a miniature hand-throwing type, and seven are small fixed-wing, One is a helicopter and the other two are airships, but they have not yet been transformed into productive forces, and they have not yet been able to form large-scale production. No one has successfully adopted the method of catapult takeoff, so it is not suitable for mountainous areas with poor sliding conditions.
