Embodiment Construction

[0043] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0044] A modeling and simulation method of spacecraft information system based on Modelica language, which combines information system modeling and simulation theory with Modelica technology system to form an object-oriented declarative information system modeling method for constructing non-causal information systems Model library; at the same time, according to the needs of non-causal modeling and simulation, an information system modeling and simulation system is developed to realize the construction, management and simulation analysis of component models and information system models.

[0045] Most of the components of the information system have a relationship of communication and interaction with each other, and the components have no explicit input and output. Such communication and interaction lead to an implicit system of...

Abstract

The invention discloses a spacecraft information system modeling simulation method based on a Modelica language. According to the method, an information system modeling simulation theory and a Modelica technological system are combined to form an object-oriented statement-type modeling method used for constructing a non-causality information system model base; and meanwhile a modeling simulation system is developed and used for realizing construction, management and simulation analysis of a component model and an information system model. Through the method, it is not needed to decouple an information system or stipulate a component input and output order and an equation solving order, the simulation system can determine the equation solving order according to an equation system data stream environment only in the solving process, therefore, the difficulty and complexity of information system modeling are greatly lowered, modeling workload is lowered, errors brought by manually designating the solving order are avoided, the reusability, expandability, flexibility and knowledge accumulation capability of the models are remarkably improved, and modularization, parameterization and visualization are realized under the support of the modeling simulation system.

Description

technical field [0001] The invention belongs to the technical field of spacecraft information system simulation, and in particular relates to a modeling and simulation method for a spacecraft information system based on Modelica language. Background technique [0002] The dynamic storage characteristics of the spacecraft information system is an important performance index of the spacecraft information system (hereinafter referred to as the information system). The quality of the dynamic storage characteristics directly affects whether the system can work normally. important topic. In the early days, the research on the spacecraft information system (hereinafter referred to as the information system) mainly used the engineering test method, and the engineering test had certain limitations in improving system performance, safety, reliability and economy, for example, it was necessary to establish a complete set of test systems , and it is difficult to change the structure an...
