Aeronautics electronic system interface management method based on models

Abstract

The present invention relates to an aeronautics electronic system interface management method based on models, which comprises the following steps of: establishing a data hierarchical model; establishing a data type model; establishing a rule configuration model; based on the data hierarchical model, the data type model and the rule configuration model, forming a data template; according to data of a real type of aircraft, carrying out interface data design on the real type of aircraft in a form of the data template; carrying out statistics and analysis on designed interface data; and processing the interface data to generate an ICD file for a designer to use or generate a header file to be directly provided for a developer. According to the interface management method, the modeling idea is used as the core and interface design and management of an aeronautics electronic system on the basis of the uniform data are implemented; and meanwhile, data interaction with the integral aeronautics electronic system about the design process can be implemented. According to the present invention, interface management can be carried out and data support can be provided in the integral developing process of the aeronautics electronic system.

Description

technical field [0001] The invention belongs to the technical field of avionics, relates to the interface management of an avionics system, and in particular relates to a model-based avionics system interface management method. 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 ...

AI Technical Summary

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
