The invention relates to a reconstruction decision-making
system and a
decision making method for a comprehensive modularized
avionics system. The reconstruction decision-making
system comprises a decision-making information collection module, a reconstruction triggering module, a reconstruction decision-making module, a warning module and a configuration execution module, wherein the decision-making information collection module is connected with the reconstruction triggering module which is connected with the reconstruction decision-making module, and the reconstruction decision-making module is connected with the warning module and the configuration execution module respectively. The reconstruction decision-making system and the
decision making method for a comprehensive modularized
avionics system have the
advantage of improving the ability of the aeroplane
avionics system to respond to different flying tasks, the ability of the aeroplane avionics system to deal with failure of different sources as well as the flying safety by selecting different reconstruction strategies according to different reconstruction requirements and resource conditions; the reconstruction decision-making system and the
decision making method provide safety evaluation and feasibility evaluation of a reconstruction scheme during selection of reconstruction schemes, and therefore the
system safety after reconstruction is improved; the system is allowed to make degradation reconstruction when high-safety avionics functions are failed, the available reconstruction resource scope of high-safety-requirement avionic functions is enlarged, and the guarantee of reconstruction to the
system safety is improved.
