Method for designing airborne optical fiber strapdown heading attitude system based on MBSE model

Abstract

The invention provides a design method of an airborne optical fiber strapdown heading and attitude system based on an MBSE model, belongs to the technical field of navigation design, adopts the MBSE model to describe the optical fiber strapdown heading and attitude system, establishes a connection relation of each demand through entries of the demands, realizes a tracing management system of the demands, and provides a method for designing the airborne optical fiber strapdown heading and attitude system based on the MBSE model. The method can effectively prevent designers from increasing subjective intentions in development and design, and solves the prominent problems of randomness, ambiguity and the like of demand transmission in the scientific research process, thereby being beneficial to improving the forward design capability; through three steps of demand analysis, function analysis and design integration, system principles and function logic are simulated and analyzed before a product is put into manufacture, system characteristics are comprehensively and meticulously mastered, and a simulation test is performed, so that logic defects of design can be reduced, system functions are perfected, the number of times of physical tests is reduced, and the cost is reduced; the research and development period is shortened, and the research and development quality and efficiency of the airborne optical fiber strapdown heading attitude system are improved.

Description

technical field [0001] The invention belongs to the technical field of navigation design, in particular to a design method of an airborne fiber optic strapdown attitude system based on an MBSE model, and applies model-based system engineering (MBSE) to the design of an airborne fiber optic strapdown attitude system method. Background technique [0002] With the rapid development of new technologies, the design of the airborne fiber optic attitude system is facing more and more problems.

[0002] With the rapid development of new technologies, the design of the airborne fiber optic attitude system is facing more and more problems. First, the airborne fiber optic strapdown attitude system is becoming more and more complex, and the degree of system integration is getting higher and higher. How to improve it The traditional development and management process in the form of documents has become an important issue to improve design efficiency; second, the development cycle of the system is getting shorter and shorter, and the iteration of design requirements is becoming more and more frequent. The traditional "manufacturing, testing, remanufacturing, and remanufacturing The research and development model of "test" is costly and long-term. How the design team conducts rapid system design and comprehensive verification in the initial stage of system design is also a new problem faced by system development.
