Avionics design method based on model

Abstract

An avionics design method based on a model comprises the steps: analyzing data interfaces from an avionics system level to a physical level, and establishing a hierarchical model of the data interfaces from top to bottom based on scenes, behaviors, functions and architecture of an avionics system; and verifying the interface control file according to the hierarchical model. The data interface is subjected to hierarchical structural design, mapping of interface traceability and integrity of scene-behavior-function-architecture is realized, transitivity of system functions and consistency of connection are verified, and rapid interface test verification and interface demand confirmation are realized. According to hierarchical construction, hierarchical mapping is performed on the system function and behavior model, a system architecture design interface is output, and then actual bus interface data corresponding to the EICD physical hierarchy is formed.

Description

technical field [0001] The invention relates to the technical field of avionics system design, in particular to a model-based avionics system design method. Background technique [0002] The avionics system refers to a complex that uses a distributed computer to cross-link various airborne electronic subsystems through a multiplexed data bus. It integrates existing single-function decentralized systems, such as communication stations, radars, and navigation equipment. Taking into account both vertically and horizontally, making overall arrangements to form a multi-functional comprehensive system. It can realize the measurement, collection, transmission, processing, monitoring and display functions of information, and complete tasks such as flight control, engine control, navigation, and performance management. [0003] The signals of the avionics system are numerous and complex. During the design process of the avionics system, it is necessary to clearly define the data int...

Problems solved by technology

[0004] However, in the data interface design of the current avionics system, the description forms of various data interfaces are not uniform; and most of them are maintained and stored in the form of paper documents

It is not conducive to the traceability and unified management of various data, it is not convenient to view, retrieve and use various data formats, and it is difficult to provide services for subsequent airborne software development, data acquisition and development of related simulation tools
