Fig. 1 is a flowchart of an embodiment of a method for translating a graphic icon of a modeica model according to the present invention, and as shown in fig. 1, the method for translating a graphic icon of a modeica model according to the embodiment of the present invention includes the following steps:
s101, reading the graphic icon information in the Modelica annotation;
specifically, the Modelica is an open, object-oriented and equation-based computer language, can span different fields, and conveniently realizes modeling of a complex physical system, and comprises the following steps: mechanical, electronic, electrical, hydraulic, thermal, control, and process oriented subsystem models. Most simulation platform software can export the Modelica model into a real-time model format, a C code and the like required by mainstream real-time simulators such as S-Function available for Simulink, FMU and NI which meet FMI standards. More and more industries are beginning to use the Modelica language for model development. In particular in the automotive sector, for example: world-known companies such as Audi, BMW, Daimler, Ford, Toyota, VW, etc. are using Modelica to develop energy-saving automobiles, improve air conditioning systems for vehicles, etc.
The Modelica graphic icon is expressed using an annotation (annotation) syntax. Modelica graphic expression is annotation (Diagram (… …)); the Modelica Icon is expressed as annotation (Icon (… …));
the Modelica graphic element comprises: component images (block), conventional images (rectangle, ellipse, multi-segment line, polygon), text, pictures, interfaces, connecting lines.
Modelica graphic attributes include: position, size, filling color, border thickness, font size, transparency.
Reading the graphic icon information in the Modelica annotation through the reading module 10;
s102, analyzing the graphic icon information;
specifically, the graphic icon information is analyzed by the analysis module 20 to obtain the graphic elements and the graphic attributes in the graphic icon information.
S103, converting the analyzed graphic icon information into internal data;
specifically, a Modelica-SVG protocol for displaying Modelica graphic icons by using SVG format pictures is designed based on Modelica modeling specifications and xml specifications, and the graphic information is converted into internal data according to the Modelica-SVG protocol.
The contents of the Modelica-SVG protocol are as follows: grouping the graphical icon information, distinguishing component information, connection information, graphical information and the like. Classifying the component information, and distinguishing icon information (icon), graphic information, port information and the like; for example: and classifying according to roles by using the field type as an identifier. The port class contains graphical information, example: id is used as a unique identifier, polygon represents geometric information, description represents text information, category represents classification information, and transform and isConnector do not need; the connection class comprises graphic information, connection source information and connection target information; for example: id is used as a unique identifier, line represents geometric information of the connecting line, and source and target represent information of two connecting ends. Graphical information, examples, containing geometric information and styles, all represented by attributes;
according to the specification of Modelica modeling, the x coordinate axis of the xy rectangular coordinate system is increased from left to right, and the y coordinate axis is increased from bottom to top; the SVG graphic specification specifies that the x coordinate axis of the xy rectangular coordinate system is increased from left to right, and the y coordinate axis is increased from top to bottom. Therefore, when generating an SVG graphic file, the coordinate system needs to be turned upside down.
S104, serializing the internal data into SVG codes;
specifically, basic graphic information, interface information and connecting line information in the serialized internal data are SVG codes; the character information in the serialized internal data is SVG codes, and at the moment, attention needs to be paid to that the characters always keep forward no matter how the coordinate system is turned over; the component information in the serialized internal data is SVG codes, and at the moment, attention needs to be paid to the fact that characters in the component always keep forward no matter how a coordinate system is turned over;
and S105, outputting the SVG graphic file based on the SVG code.
In particular, SVG is an image file format, which is called Scalable Vector Graphics in english, meaning Scalable Vector Graphics. It is developed by World Wide Web Consortium (W3C) alliance based on XML (extensible Markup language). Strictly speaking, it should be an open-standard vector graphics language that allows you to design exciting, high-resolution Web graphics pages. The user can directly draw the image with the code, open the SVG image with any word processing tool, make the image have interactive function by changing part of the code, and can insert into HTML at any time to watch through a browser.
Based on Modelica modeling specification, xml specification and the homologous Modelica-SVG protocol, the method for using the SVG format graphics to represent the statement type graphics icons in the Modelica model is realized, and the requirements of users on checking and interaction of the Modelica online model in the collaborative modeling and distributed simulation scenes are supported.
