Semi-independent flight control system of unmanned airship and control method thereof

Abstract

The present invention is the flying control system and method for semi-autonomous flying of unattended aeroboat. The control system includes aeroboat borne system and ground system, the aeroboat borne system has structure comprising sensors, A/D converter, monolithic computer, analog multiplexer, executor, aeroboat borne data transmission module, remote controlled signal receiver, etc. connected together; and the ground system has PC, ground data transmission module and remote signal emitter. The aeroboat borne data transmission module and the remote controlled signal receiver in the aeroboat borne system associate with the ground data transmission module and the remote signal emitter of the ground system via RF signal. The control system can identify the mode channel signal and realize the mode switching among remote control, local remote control and autonomous flying.

Description

technical field [0001] The invention relates to a control system of an aircraft and a control method thereof, in particular to a semi-autonomous flight control system of an unmanned airship and a control method thereof. Background technique [0002] An airship is a lighter-than-air (LTA) aircraft, and its main components include an airbag filled with light gas, one or several thrust-generating engines, a pod, an empennage, and a control system. The main difference from heavier-than-air aircraft is that airships rely on lighter-than-air gases (such as hydrogen, helium, or hot air) sealed in airbags to provide all or most of their lift to support the airship and its load in the air , the lift has nothing to do with the flight speed. The main difference between the airship and other lighter-than-air aircraft is that the airship is powered and steerable, powered by the engine, and the pitch and direction of the airship are controlled by manipulating the elevator and rudder on t...

Problems solved by technology

Obviously, there are deficiencies in the remote control method. For example, the remote control distance is limited. When the target location is in a place that is difficult for the remote control to reach (such as a large forest or a swamp), the unmanned airship cannot fly; the remote control is labor-intensive, and the remote control keeps looking up. Airship side operation, especially in some long-term flight conditions, it is easy to get tired, etc.

In this regard, research institutions such as the AURORA project in Brazil and the System Structure and Analysis Laboratory of the French National Center for Scientific Research have done a lot of work, but their research is based on high-cost sensor groups, which is not conducive to commercialization
