| Abstract: | This paper introduces a design precept using triple-redundant technology to promise the software reliability for rocket fly control, then selects a proper redundancy mode to establish a triple-redundancy fly control software digital simulation platform. The software flowcharts to realize the key technologies project of redundancy strategy and synchronization arithmetic are provided. The test result shows that the precept design is properly designed and the task of fly control computer redundancy management is preferably finished, which effectively ensured the reliability and error toleration of the system. |
