Reconstruction decision-making system and decision making method for comprehensive modularized avionics system

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of integrated avionics, in particular to a reconfiguration decision-making system and a decision-making method of an integrated modular avionics system. Background technique [0002] Integrated Modular Avionics (IMA, Integrated Modular Avionics) adopts a resource-sharing system architecture, on which a high-performance general-purpose platform provides more complex functions while reducing the number of dedicated modules, which reduces manufacturing and maintenance costs and enables IMA has gradually begun to replace the traditional combined avionics system and become the preferred avionics architecture for the new generation of passenger aircraft. [0003] In order to reduce the number of configured subsystems, save aircraft weight, space and cost, improve resource utilization, and reserve space for subsequent expansion, IMA adopts a combination of a series of standardized general-purpose functional modules...

AI Technical Summary

Problems solved by technology

At present, the IMA system mainly uses the general resource management system to manage the resources of the modular avionics system, and realizes the switching of avionics functions and the backup protection of the system functions by preloading multiple sets of avionics system configuration schemes. Dealing with pre-set tasks or protecting against predictable system resource failures, it is difficult to complete complex flight tasks, and it is also difficult to resist unexpected functional failures, thus bringing hidden dangers to the safety of the aircraft
