Modelica-based multi-user synergic modeling system

Abstract

The invention discloses a Modelica-based multi-user synergic modeling system. The system comprises a Modelica-based system model base, a model multi-user synergic developing module, a web-based model data management module, a cloud computing-based simulation management module, a model health monitoring module and a model design and optimizing module, wherein the system model base is used for supplying a model to the model multi-user synergic developing module; the model multi-user synergic developing module is used for updating the model of the system model base; data is exchanged between the model multi-user synergic developing module and the model data management module; a user submits a simulation task to the model data management module and then the simulation management module runs; the model health monitoring module is used for monitoring the result parameter change conditions in the running process in real time; the model design and optimizing module is used for supplying a multi-dimensional view displaying simulation result parameter. According to the invention, different synergic management modes can be dynamically adjusted according to the requirements of the group, so that the effects of efficient management and synergic development can be achieved.

Description

technical field [0001] The invention belongs to the field of computer simulation and modeling, and in particular relates to a multi-person collaborative modeling system, which involves full lifecycle management of model data. Background technique [0002] Modelica is an open new multi-domain unified modeling language proposed by the international simulation community in 1997. Object-oriented technology and Matlab's numerical and matrix mechanism, so it has extremely powerful modeling functions. Object-oriented and non-causal are the biggest advantages of the Modelica language. The object-oriented modeling method has the characteristics of data encapsulation, layering, connection and inheritance, etc. It is easy to reduce the occurrence of errors and realize the reuse of models. The so-called non-causal modeling is to express the model equation in a neutral and natural form, so that there is no need to consider the calculation sequence more, avoiding the tedious derivation ...

AI Technical Summary

Problems solved by technology

[0005] In complex Modelica models, general version management tools (SVN, Git) are based on text-based version management. When viewing the model, you can only see the text view, and you cannot preview the changed version of the specific components of the model in real time. Work efficiency is very low

Especially when the file of a model is relatively large, the support of existing version management tools for large files shows that there are congenital deficiencies

[0006] In addition, there is a security mechanism problem in the existing collaborative modeling technology. In the past, everyone copied a model, and there were many security risks during the copying process. This is especially important for units with high security requirements.
