[0041] Principles of constructing a two-dimensional digital engineering library:

[0042] 1. Database design: Design the database structure to store the relationship between SVG graphic elements, attribute parameters and components. Use efficient data storage and retrieval mechanism to ensure the rapid response of the graphics library.

[0043] 2. Graphics library design: Based on the SVG standard, develop a graphics library module to implement functions such as creation, editing, saving, and calling of graphic elements, and support user-defined graphic elements and attribute parameters.

[0044] 3. Interactive interface design: Design a friendly user interactive interface and provide a graphical operation interface to facilitate users to quickly call and modify two-dimensional digital engineering symbols;

[0045] Changes and improvements compared to existing technologies:

[0046] 1. Standardization and compatibility improvement: Strictly follow the SVG standard to ensure that the generated two-dimensional digital graphics library has good compatibility and portability. As an open and widely supported graphics standard, SVG enables this graphics library to be seamlessly integrated and applied in a variety of platforms and software environments, greatly expanding its application scope.

[0047] 2. Enhanced professionalism of substation buildings: Aiming at the specific field of substation buildings, the patent of this invention deeply analyzes its unique component elements and attribute parameters, designs a set of special two-dimensional digital graphics library, and improves the professionalism of the graphics library.

[0048] 3. Improved design efficiency and quality: By building a standardized graphic library, the rapid call and modification of two-dimensional digital graphic symbols of substation buildings is realized. Designers can easily select appropriate graphic elements from the graphic library and customize them as needed, which greatly improves design efficiency and flexibility;

[0049] Solve the problem of lack of unified standard graphics library at this stage: In the prior art, there is a lack of unified standard two-dimensional digital graphics library for substation building, which leads to compatibility issues between different platforms and software. The patent of this invention effectively solves this problem by following the svg standard, and improves the versatility and scalability of the graphics library;

[0050] Improved design efficiency and accuracy: Traditional design methods require designers to manually draw a large number of graphic elements, which is not only time-consuming and labor-intensive, but also prone to errors. This patented invention builds a standardized graphic library to achieve rapid call and modification of graphic elements, greatly improving design efficiency and accuracy;

[0051] Reduced costs and maintenance difficulty: Since the graphics library is standardized and can be shared and used universally, duplication of work and waste of resources are avoided. At the same time, the database-based management method also simplifies the data maintenance process and reduces maintenance costs;

[0052] Database construction: Build the database structure to store SVG graphic elements and attribute parameters in a structured manner, while ensuring the relationship between components. Use the preset data storage and retrieval mechanism to classify and store the icons professionally to ensure the regularity of the data structure of the graphic library and the rapid response of functions.

[0053] Graphics library construction: According to the analysis results of SVG standard and 2D data engineering symbols, the graphics library system module is constructed. The management module including creation, editing, saving, calling and other functions of graphic elements is realized, and users are supported to modify graphic elements and attribute parameters by themselves, which greatly improves the degree of freedom and flexibility.

[0054] This paper aims to explain the design and development principle of a new graphics library, which is designed to meet the SVG standard and is optimized specifically for the two-dimensional digital engineering drawing requirements of power engineering substation buildings. By deeply analyzing the characteristics of SVG vector graphics and combining the specific requirements of the elements, attribute parameters and other components of power engineering substation buildings, a system that can quickly call and modify two-dimensional digital engineering symbols is constructed to improve the efficiency and standardization of engineering drawing design.

[0055] Analyze the requirements of SVG vector graphics and 2D digital engineering symbols, and elaborate on the details to form the results of sorting. According to the sorting results, build a 2D digital graphics library for substation buildings, support the rapid call and modification of 2D digital engineering symbols, and the graphic element symbols meet the requirements of SVG vector graphics, 2D digital engineering drawing specifications, and substation building engineering drawing requirements;

[0056] The present invention proposes a design method for a two-dimensional digital graphic library of a substation building based on the SVG standard, which associates the design information parameters of each component in the professional design of the substation building of the power grid project with the standard of "Power Grid Project Two-Dimensional Digital Engineering Drawing Design and Delivery Specification", establishes a mapping relationship, and forms a two-dimensional digital engineering graphic symbol that meets the requirements of the specification. A two-dimensional digital engineering drawing library is constructed, and the two-dimensional digital engineering graphic symbols of each professional component are integrated. The standard classification and rapid drawing of engineering graphics symbols are realized by means of a graphic library, so as to solve the problem that the current two-dimensional digital engineering drawing process is laborious and error-prone.
