A multi-level modeling design method for large-scale distributed integrated modular avionics system dima

Abstract

The invention discloses a multilayered modeling design method for a large-scale distributed comprehensive modular avionics system DIMA. The method comprises the following steps: respectively configuring a hardware layer, a software layer and a network layer of an avionics system and modeling; designing an evaluation criterion according to demands of engineering design; optimizing and evaluating an established hardware configuration layer model, a software configuration layer model and a network configuration layer model by using a single-target / multi-target optimization algorithm to obtain an optimized hardware layer configuration vector Xdevice, an optimized software configuration layer vector XTask and a network layer configuration vector XNetwork so as to finish configuration of network connection of DIMA equipment, avionics system tasks and DIMA equipment. Layered configuration of a system layer, the hardware layer, equipment in a mounting layer, tasks and networks in a large-scale and multilayered avionics system is implemented, modeling layers of the whole avionics system are comprehensive and specific, moreover, expandability is high, and meanwhile, safety and reasonability are enhanced.

Description

technical field [0001] The invention relates to the technical field of aeronautical equipment design, in particular to a modeling design method of a large-scale, multi-level distributed comprehensive modular avionics system. Background technique [0002] The avionics system is the core of modern aircraft equipment informatization, and is the information perception, display and processing center of the aircraft. Its performance and technical level directly determine and affect the overall performance of the aircraft. It can be said that without a high-performance and high-level avionics system, it is impossible to have a truly large domestic aircraft. It is precisely because of the important position of the avionics system in the entire aircraft, the design of the avionics system architecture will directly affect multiple objectives such as the weight of the aircraft and operating costs. However, due to the continuous development of science and technology, the complexity an...
