RESEARCH ON DISTRIBUTED INTEGRATED MODULAR AVIONICS SYSTEM ARCHITECTURE DESIGN AND IMPLEMENTATION

A well-designed Distributed Integrated Modular Avionics (DIMA) should keep the complexity of system interconnections to a minimum with the constraints set by communication links, LRM size, and fault tolerance requirements. In this paper, a basic DIMA model is put forward and the design philosophy is detailed for constructing DIMA system framework which enhanced capabilities with improved reliability and lower cost. The paper analyzes the system framework model, ability and effectiveness, discusses the organization mode, management mode and process scheduling management mode of DIAM system, and created an organization and management mode for DIMA system architecture. Furthermore, the key enable technologies for DIMA system implementation are analyzed which can guide implementing DIMA system.
