Embodiment Construction

[0017] like figure 1 Shown is a schematic diagram of the system structure, and the specific steps of the efficient call method of the combined model components are:

[0018] The first step is to build a system for the efficient invocation of a composite model component

[0019] The system for efficiently invoking combined model components includes: combined model component description CM_X module, combined model component initialization CM_I module, combined model component proxy CM_P module, and combined model component deconstruction CM_D module.

[0020] The functions of the CM_X module are: describe the composition of the combined model components, internal information interface relations and instantiation information;

[0021] The function of the CM_I module is: to establish the information interface relationship between the upper model component and the internal sub-model component of the composite model component, and create an instance of the sub-model component;

Abstract

The invention relates to an efficient calling method of a combined model component. The method comprises the following steps: calling an upper layer simulation engine by a CM_I module to generate a sub-component example at the interior of the combined model component and realize the calling of the combined model component through a CM_P module; directly inserting event information of the combined model component into the upper simulation engine so as to realize that a simulation engine of a horizontal alignment structure is used for replacing a simulation engine of a tree-shaped gradational structure. Invalid event scheduling just for scheduling control is used, and the cost of dynamic memory is reduced, thus the operating efficiency of a simulation system is greatly improved.

Description

technical field [0001] The invention relates to a calling method of model components, in particular to an efficient calling method of combined models. Background technique [0002] For a simulation system that supports hierarchical modeling, how the simulation engine invokes the combined model components directly affects the operating efficiency of the simulation system. The usual implementation method is to use a hierarchical simulation engine, that is, an independent composite model component has an independent simulation engine. By constructing an empty event message for the independent simulation engine and inserting it into the upper-level simulation engine, the simulation of the upper-level simulation engine and the combined model component is realized. Engine timing coordination. This implementation method is simple and easy to implement, but the construction of empty messages causes invalid event sorting and empty event calls, resulting in low call efficiency and la...
