Computer system suitable for reliable flight control of unmanned aerial vehicle

Abstract

The invention provides a computer system suitable for reliable flight control of an unmanned aerial vehicle. The computer system comprises at least two computer channels and flight control buses corresponding to the computer channels, respectively, wherein the two computer channels are independent to each other and same in structure. Any one of two computer channels comprises an instruction branchand a monitoring branch in synchronized operation. The instruction branch comprises a first processor and a first bus interface, and is connected to the bus corresponding to the channel through the first bus interface. The monitoring branch comprises a second processor and a second bus interface, and is connected to the bus corresponding to the channel through the second bus interface. A first voting surface and a second voting surface are respectively set at the input and output ends of the computer channels, respectively and used to take a vote on input data of the two branches and solutionresults output by the instruction branch and the monitoring branch. The computer system provided by the invention can effectively improve reliability and safety of a flight control computer and a flight control system.

Description

technical field [0001] The invention relates to a computer system suitable for high-reliability flight control of unmanned aerial vehicles, especially suitable for reliable control of the flight of high-altitude long-endurance unmanned aerial vehicles, and belongs to the technical field of flight control. Background technique [0002] The flight control system is the core system of the UAV, and the flight control computer is the core key equipment of the flight control system, and its reliability index is extremely high, especially for high-altitude and long-endurance UAVs. [0003] At present, in the field of high-altitude and long-endurance UAVs, similar redundancy technology is often used, such as dual-redundancy or triple-redundancy flight control computer, which greatly improves reliability compared with no-redundancy flight control computer, but similar redundancy technology alone There will be problems of common mode failures leading to avalanche disasters. In additio...
