Uav Flight Control System For Real-time Redundancy, Software Design

With the development of high altitude UAV (unmanned aerial vehicle) in the military, it is important to research a high altitude and long endurance UAV which can fly under different kinds of faults. The paper studies and designs triplex Hot-redundancy flight control computer's management of remaining system from software and hardware. The point carries is to discuss and practice from a software of redundancy design and to carry through experiment and imitate. The main structure of this paper is as follows:1. A document review is made to analyze the present status and trend of unmanned aerial vehicle's technology, and relate to the application of redundancy management.2.The paper completes the configuration and selection of the whole project's Hot-redundancy structure, then the paper gives the hardware requirement the software requirement. From the requirement, I put forward the hardware design and software design.3.Build triplex Hot-redundancy flight control computer's platform .Design the system according to the hardware project, choose of the boardcard, design the CCDL and build the card of triplex Hot-redundancy. Designed to build up the hardware foundation for software of redundancy.4. Textual point is triplex Hot-redundancy flight control computer's software. The paper completes the configuration and selection of the whole project's Hot-redundancy structure, then the paper gives the hardware design and the software design.5. The experiment and the semi-physical simulation of triplex Hot-redundancy flight control computer is conducted in the laboratory. The experiment's result shows that triplex Hot-redundancy flight control computer's software design is rational, feasible and reliable.
