Small-sized depopulated helicopter independent flight control system

Abstract

The invention relates to a miniature unmanned helicopter auto flight control system which comprises an on-board control system, wherein, an on-board computer gets signals from sensors through a serial port, and exchanges data with a ground-based computer through on-board and ground wireless Ethernet access points; the on-board computer carries out serial communication with a digital signal processor to control a steering engine set of the unmanned helicopter; a remote control signal receiver outputs to the digital signal processor and then is connected with the on-board computer through a serial port, and an auto control signal and a ground remote control signal are accumulated to get a current steering engine control signal. And the auto flight control system also comprises a ground control system, wherein, the ground-based computer transmits flight control instructions to the on-board computer and receives and records flight data; through operating a ground helicopter remote controller, manual control instructions can be transmitted to the on-board remote control signal receiver via wireless radio frequency signals. The invention can improve the auto flight ability of the miniature unmanned helicopter, strengthen system reliability, expand the application range of the unmanned helicopter and enable the helicopter to complete given missions beyond the visual range.

Description

technical field [0001] The invention relates to a control technology of an aircraft, in particular to an autonomous flight control system of a small unmanned helicopter. technical background [0002] With the development of autonomous control technology, unmanned aerial vehicle (UAV, Unmanned Aerial Vehicle) has begun extensive research all over the world. Unmanned helicopters have many advantages that unmanned fixed-wing aircraft do not have, and have unique flight performance and use value. It has no casualties, small size, low cost, and strong battlefield survivability; in terms of military use, unmanned helicopters can not only perform various non-lethal tasks, but also perform various soft and hard lethal tasks, including reconnaissance, surveillance, target Interception, bait, attack, communication relay, etc.; in terms of civilian use, unmanned helicopters have broad application prospects in aerial photography, atmospheric monitoring, traffic monitoring, resource exp...

AI Technical Summary

Problems solved by technology

[0004] However, in the prior art, unmanned helicopters have achieved pre-programmed stable flight, but compared with manned aircraft and remote-controlled model aircraft, their maneuverability is very limited, and they do not yet have the ability to complete tasks autonomously, especially is a military mission capability

Therefore, the autonomous capability and system reliability of unmanned helicopters cannot meet the requirements at present, and the application range of unmanned helicopters is limited, making it impossible to complete a given task within the beyond visual range
