Embodiment Construction

[0090] The present invention combines the standards and components of the architecture, from the perspective of the system, through the gradual refinement of system functions, and using the mapping method of each function or sub-function to the FACE component as a clue, proposes a hierarchical and componentized modeling method under the architecture, specifically Modeling process such as figure 1 shown.

[0091] Step 1: System function analysis: perform iterative analysis of system functions according to system requirements, divide a system into several subsystems, divide a subsystem into several subsystems or functions, and refine a function into multiple sub-functions, so that the system functions as much as possible refinement. Express the final system function analysis results in a system function tree, such as figure 2 shown.

[0092] The system function tree contains two types of nodes: system nodes and function nodes, where system nodes are divided into system nodes...

Abstract

The invention discloses a software system modeling method based on a FACE (Future Airborne Capability Environment) architecture, which comprises methods of system componentization, data modeling, system I / O service modeling, component transmission service modeling and the like. The modeling method disclosed by the invention can guide modeling of a domestic avionics system architecture, and can bepractically applied as theoretical foundations for development of a tool chain and a platform which are related to system modeling under the FACE architecture. The software system modeling method is beneficial for improving software quality and development efficiency, reinforcing software portability, saving development cost, facilitating rapid integration of a system, shortening a development period of the system and pushing formation of a uniform open software architecture standard in the domestic aviation field. The software system modeling method can be applied to software-intensive industries in the fields of high credibility, high reliability and high security, such as the aviation field, the aerospace field and the like.

Description

technical field [0001] The invention relates to a software system modeling method based on the FACE framework. Background technique [0002] The task importance and functional complexity of the new generation of avionics systems are getting higher and higher. At the same time, the rapid development of electronic information technology and computer technology, as well as the highly integrated design requirements have brought many challenges to the avionics system. Among them, the airborne software and Tight hardware binding, difficult system upgrades, and poor reusability are key factors leading to high development costs for avionics systems. The avionics system of my country's fourth-generation aircraft is still provided by a single developer for a specific set of needs, resulting in cumbersome system upgrade procedures, and the developed hardware and software cannot be reused on different types of aviation platforms or various similar functions. . At present, there are gen...
