Airborne system digital design verification system and method

Abstract

The invention discloses an airborne system digital design verification system and method and belongs to the technical field of system engineering. The system disclosed by the invention comprises a top-layer digital design system and a domain engineering layered digital design system, wherein the top-layer digital design system comprises a demand analysis module, a top-layer analysis design module and a top-layer model test and verification module; and the domain engineering layered design system comprises a single-domain analysis design module, a single-domain test and verification module, multi-domain collaborative design module and a multi-domain model simulation verification module. The method disclosed by the invention comprises the following two steps: concept model machine design of an airborne system and virtual model machine design of the airborne system, wherein the former step comprises the following three sub-steps: demand analysis of the airborne system, system analysis of the airborne system and system design of the airborne system. The system and method disclosed by the invention can be used for supporting the digital analysis, design and verification of the airborne system, realizing 'design and verification first, implementation later' of the airborne system, avoiding the problems of long period, high cost, great risk and the like caused by the 'design and implementation first, verification later' of the traditional design method.

Description

technical field [0001] The invention relates to the field of aircraft airborne system design, in particular to an airborne system digital design environment and method, and belongs to the technical field of system engineering. Background technique [0002] Aircraft airborne system is a typical complex reactive system. Its traditional design method is a document-driven design method. Its disadvantage is that designers cannot evaluate the design scheme before the physical prototype of the airborne system is realized. Therefore, the design There may be many ambiguities and errors in the scheme, and these ambiguities and errors can only be discovered when the system is integrated later, and the cost of modifying these ambiguities and errors is huge. [0003] Digital design is a sharp sword to solve the shortcomings of traditional document-driven design methods. Its technical connotation is to eliminate the ambiguity and errors in design schemes and decision-making by construct...
