In the aerospace field of this project, the integrated avionics architecture has the characteristics of multiple bus protocols, complex interface conversion types, and high redundancy in resource allocation. It has a development history of more than 20 years driven by demand and technology, especially in the past ten years., remarkable progress has been made. Especially in the civil aircraft field, with the advancement of the domestic C919 project, it has also brought a new guidance and new development for the domestic civil aircraft industry. Of course, the current integrated avionics system has encountered many difficulties in actual use, exposing many shortcomings, which need to be solved and improved urgently. Therefore, in the next ten years, while solving the problem of economic affordability, the integrated avionics system will continue to develop in a more integrated, information-based, technology-based, modular and intelligent direction, and the integrated avionics system will also have a breakthrough leap in its functions, performance and reliability, maintainability, supportability, testability and comprehensive effectiveness. In the C919 project, although the design of avionics systems is dominated by China, most avionics subsystem products are shelf products, or their functions are defined by various suppliers. The design capabilities of the overall avionics system are limited. The cross-linking requirements of the aircraft level system are derived from the actual needs of each subsystem, rather than the requirements after top-down optimization. In practice, the reconfiguration of the avionics architecture will occur, resulting in frequent changes in system requirements, greatly increasing the development cycle and cost. In addition, when designing avionics system requirements and architecture, they are often transmitted through documents, which cannot better reflect the traceability and dependence of requirements and architecture. The C919 avionics system configuration is the responsibility of AVIAGE (using GE's open architecture), and the design of the comprehensive avionics architecture independently designed in China is still blank. In order to solve these problems, based on a model-driven systems engineering method, a unified data model is used to describe the system, and the configuration of resources is associated with the system's requirements model, interface model, and behavior model, thereby ensuring the integrity and consistency of the configuration. With the increase of resident applications of integrated avionics systems, the cross-linking relationship and demand dependence of system architecture have also become complex. Through interface configuration technology and resource configuration technology, architecture configurations and corresponding tools are built in the system design context to realize the dynamic configuration of avionics architecture. This technology will not affect the configuration methods and methods of the avionics system with the increase of equipment and functions, and can realize modularization of the avionics system architecture design, standardization of configuration processes, and explicit data transmission. This project& ldquo; General configuration technology for integrated avionics systems& rdquo; Focusing on the integrated avionics system architecture designed in the project, a model-based systems engineering method is used to associate resource configuration with the system requirement model, interface model and behavior model. An object-oriented interface design method and complex multi-bus type-oriented data conversion technology have been proposed to realize the configurable common resources of the system, and a reusable avionics architecture configuration tool chain has been developed to meet the dynamic construction requirements of the system architecture. Improve the overall R & D capabilities and market competitiveness of avionics systems. This project has software copyright.
