The specific technical indicators are as follows:
(1) Support platform-level and system-level system fault tolerance policy configuration, status monitoring and fault diagnosis;
(2) Research and implement the backup, reconstruction and downgrade reconstruction capabilities of multi-platform resources;
(3) Build a prototype demonstration environment for multi-platform avionics system fault tolerance and dynamic reconfiguration technology.
This project mainly completed the following research contents:
(1) Comprehensive fault-tolerant and reconfiguration management architecture design for multi-platform avionics systems
Based on the analysis of fault tolerance management needs of multi-platform avionics systems, and on the premise of building a multi-platform "large avionics system", explore the formation of the basic configuration concept of fault tolerance and reconfiguration of multi-platform avionics systems, and form a comprehensive fault tolerance and reconfiguration management architecture conceptual plan for multi-platform avionics systems based on information network.
(2) Multi-platform avionics system fault tolerance and reconfiguration management software architecture design
Based on the research on the comprehensive fault-tolerant and reconfiguration management architecture of multi-platform avionics systems, a fault-tolerant software architecture for multi-platform avionics systems is established. The architecture can be constructed in two layers from the system and system: one layer is the internal fault-tolerant management software in the platform, and the other layer is cross-platform fault-tolerant management software. Eventually, an open and reconfigurable software architecture design solution for multi-platform avionics systems was formed.
(3) Fault tolerance and reconfiguration management strategy for multi-platform avionics systems
Multi-platform avionics systems should have dynamic configuration and management capabilities for combat missions. On the basis of single-platform system resource management, high availability and high reliability of multi-platform avionics systems should be achieved through fault tolerance and reconfiguration of system functions between platforms. The prerequisite for system resource allocation is the need to clarify the resource requirements of combat missions and the functional configuration and status of each platform. System fault tolerance and reconfiguration management determines system fault tolerance and reconfiguration strategies based on the entire battlefield situation, mission requirements and platform capabilities. The research on this strategy should be based on the establishment of a comprehensive fault-tolerant and reconfiguration management architecture for multi-platform avionics systems and an open and reconfigurable software architecture.
(4) Development of a prototype demonstration environment for multi-platform avionics system fault tolerance and dynamic reconfiguration
In order to complete the demonstration and verification of various research contents and key technologies, a multi-platform avionics system fault tolerance and dynamic reconfiguration software prototype was developed.
