A modeling method for a unified model of the whole life cycle of avionics system

Abstract

The invention relates to an avionics system full-life-cycle unified model modeling method which includes the steps that an avionics system is decomposed into a system body, a sub-system, a device, a module and an element; a demand model, an architecture model, a behavior logic model, a man-machine interaction model, an ICD model, a hardware model, a software model and a test model are built according to the development phase dimension; a connection relation among all the models is built to form a system-level model, a sub-system-level model, a device-level model, a module-level model and an element-level model; the system-level model, the sub-system-level model, the device-level model, the module-level model and the element-level model are integrated to form the unified model. By means of the method, the avionics system full-life-cycle unified model can be built precisely, the unified model can conduct valid description on a whole software / hardware architecture, functions, interfaces, behaviors and the like of the avionics system, supports system-level comprehensive simulation and achieves seamless transmission of data in the development process.

Description

technical field [0001] The invention belongs to the technical field of avionics and relates to modeling of avionics systems, in particular to a modeling method capable of establishing a unified model of the entire life cycle of an avionics system. Background technique [0002] The rapid development of electronic technology and network technology has promoted the upgrading of avionics systems. The new generation of integrated avionics system based on the IMA / DIMA architecture has complex architecture, short development cycle, high performance and quality requirements, and needs to adopt the research and development method of model-based system engineering. The data models of the existing avionics system research and development process, such as demand models, human-computer interaction models, architecture models, ICD models (interface control document models), etc., can only support a certain research and development stage, and the correlation between the models is not stron...
