Embodiment Construction

[0040] In order to make the content of the present invention clearer and easier to understand, the content of the present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0041] The method of the invention adopts the meta-object mechanism and the system engineering design method based on the model. like Figure 9 As shown, the top-level design of complex systems first abstracts the models involved in different disciplines such as machinery, electronics, control, and hydraulics; on the basis of abstracting the commonality of models in different disciplines, the system engineering modeling language SysML is extended , use the extended SysML to construct the atomic model of the system under the framework of modules, functions, behaviors and structures, and formally define the atomic model; finally use the formalized atomic model to construct the dynamic behavior, static structure and constraint relationship of the c...

Abstract

The invention provides a meta object mechanism driven complex system top layer design method. The meta object mechanism driven complex system top layer design method comprises the steps that general characteristics of models in the multiple different subject fields involved by a complex system are abstracted out; SysML is extended according to the general characteristics of the models in the different subject fields; atomic models and coupling models are built according to extension elements of the SysML, and formalized definition is conducted on the atomic models and the coupling models; hierarchical decomposition is conducted on the service of the complex system according to the determined complex system service requirements so as to express the service of the complex system in the forms of the atomic models and the coupling models; the atom models and the coupling models are combined to form a complex system top layer model, and collaborative simulation and verification are performed.

Description

technical field [0001] The invention relates to the field of system design, and more specifically, the invention relates to a top-level design method of a complex system driven by a meta-object mechanism. Background technique [0002] Complex systems refer to those coupled systems with complex structures and both discrete state behavior and continuous dynamic behavior. Aircraft control systems, automotive electronic control systems, etc. are typical complex response systems. [0003] In the complex system design process, the designer first conducts the top-level design of the system. At this stage, designers collect user requirements, analyze, decompose and refine them, and conduct system analysis and design based on user requirements to obtain the overall design of the system. The overall design scheme is the basis for subsequent design work, which determines whether the final designed physical prototype works correctly and meets user needs. Therefore, the designer should...
