Distributed integrated modular avionics system reconfiguration parameter selection system and method

Abstract

The invention discloses a distributed integrated modular avionics system reconfiguration parameter selection system and method. The system comprises a running parameter database, a parameter selection module and a parameter output check module, wherein the running parameter database is connected with an external DIMA reconfiguration management system; the parameter selection module is connected with the running parameter database and the parameter output check module, and is also connected with the DIMA reconfiguration management system; and the parameter check module is externally connected with the DIMA reconfiguration management system. The reconfiguration parameter selection system and method havethe advantages that (1) the transmission of harmful / invalid parameters in a reconfiguration process is considered, and reconfiguration parameters are judged, so that the robustness of a reconfigured system is improved and the system security is improved; and (2) during reconfiguration parameter selection, different parameter selection and backup modes are provided, so that different system frameworks can be effectively adapted and the reconfiguration parameter selection system and method have higher practicality.

Description

technical field [0001] The invention belongs to the field of avionics systems, in particular to a system and method for selecting reconfiguration parameters of a distributed integrated modular avionics system. Background technique [0002] Integrated Modular Avionics (IMA, Integrated Modular Avionics) gradually began to replace the Federate (Federate) avionics system to become the preferred avionics architecture for the new generation of passenger aircraft, such as Airbus A380, A350, Boeing 777, 787 and large aircraft independently developed by my country C919 has chosen the IMA system architecture. The Distributed Integrated Modular Avionics (DIMA, Distributed Integrated Modular Avionics) system is an important improvement to the IMA system. It adopts a distributed system architecture and high-speed interconnection network technology, which has greatly improved system performance and scalability. Its unique dynamic reconfiguration feature can effectively resist unexpected s...

Problems solved by technology

[0004] This method has the advantages of simple control logic and high reconstruction efficiency. However, during the reconstruction process, the backup partition / module indiscriminately inherits the parameters of the failed partition / module, and there is a high probability that the backup partition / module will fail during the reconstruction process. Using some abnormal and harmful parameters failed to provide effective fault isolation capabilities between the primary partition / module and the backup partition / module, which brought hidden dangers to system security
