Avionics system interface management system based on models

Abstract

The invention relates to an avionics system interface management system based on models. The system comprises a data hierarchy model, a data type model, a rule configuration model, a data template, a data design module, a database, a data analysis module and a universal interface module. The avionics system interface management system based on the models takes the modeling thought as the core and realizes interface design and management of the avionics system based on unified data; meanwhile, data interaction with the design process of the whole avionics system is realized with a document generation technology and a universal interface technology. The system can perform interface management and provide data support in the whole research and development process of the avionics system.

Description

technical field [0001] The invention belongs to the technical field of avionics and relates to interface management of avionics systems, in particular to a model-based avionics system interface management system. Background technique [0002] Traditional avionics system interface management is aimed at the low-speed bus represented by 1553B / ARINC429 as the core, and the whole system is designed around the low-speed bus, and is designed and managed through documents. In the face of the new generation of integrated avionics technology based on IMA, AFDX or ARINC653 architecture, with the exponential growth of information volume and the need for system resource sharing, it is difficult to realize the resource allocation by simply relying on the designer's work experience. Reasonable distribution calls for new design methods and tools. [0003] In addition, specific design and practical experience show that new design methods and tools are needed to improve work efficiency. Fi...

Problems solved by technology

First of all, for the civil aircraft airworthiness certification process, it is necessary to provide complete compliance evidence from design to verification. Using the document-centered research and development method not only has a huge workload, but also it is difficult to ensure the consistency and integrity of document data, which gives Obstacles to forensics work

Secondly, it is difficult to directly apply the experience accumulated in the design of a mature model to the design of new models through documentation, which affects the effective accumulation of knowledge in the R&D process and the sharing and reuse of knowledge
