Integrated Intelligent Design System Development Of Supply And Distribution Projects

CAD software system of supply and distribution projects is one of the most widely used of computer graphics technology and aided design technology in the field of electrical engineering. Related software systems at home and abroad for supply and distribution projects design exist widely exist widely independent of each other, not be intelligent integration and so on problem in overall, local and unit graphics design, calculation and analysis, primitive property, engineering information, engineering materials and construction techniques and standards; and the new and old CAD electronic maps of supply and distribution projects can not be mutually compatible, conversion and integration; also has not been seen forming design drawing method of three-dimensional supply and distribution engineering drawings. Starting from the point of view of practical applications and economic, social benefits, this paper aims to research and develop an intelligent supply and distribution engineering CAD system which set design, drawing, calculation and analysis in one.Direct against the inadequate and problem in the practical application of the existing supply and distribution engineering CAD software system, this paper research and analysis contacting mechanism and relationship among the design of supply and distribution engineering, Drawings, data, build a description method for each component object of supply and distribution. Taking Object-oriented technology and parametric modeling technology, build standard2D and3D primitives library, at the same time, through standardization of data technology, information intelligent recognition technology and systems integration technology and so on, solve the problem of primitive entity object and the background data correlation and the compatibility of old and new drawings in supply and distribution engineering. Develop parametric drawing design system of advanced supply and distribution, intelligent generation system of cable inventory and information points table, and achieve to link the database. The framework structure of the analysis and calculation, graphics, data processing, integration of CAD system for distribution projects based on the intelligent model combines object-oriented parametric design, developed an integrated system of intelligent and aided design for supply and distribution projects that meet the needs of the actual engineering design.The system developed in this article are based on the AutoCAD platform, using the ActiveX Automation technology spreadsheet and database technology, and taking Visual Basic for application which is a visualized program language and Object ARX as a secondary development tools, to study the methods and algorithms of primitives and text information intelligent recognition, data mining and integration, two-dimensional and three-dimensional drawings of the supply and distribution graphics design, compatible with the new, old drawings and data exchange, data analysis and processing, and intelligent generation of engineering materials inventory. Some of the features in the developed system have been get practical application in the Hunan Electric Power Survey and Design Institute, and produce better benefits.How to improve the integration of the supply and distribution projects, and intelligent computer-aided design, improve the quality and efficiency of engineering design, to meet the needs of the rapid development of industrial markets and social economic, is the new research and development goals for distribution engineering CAD systems, but also the purpose of this article research and develop deeply.
