Design And Realization Of Special-Equipment Diagram Drawing Software

Along with information technology violent development, specially computer technology changing with each new day, traditional profession management pattern also corresponding occurrence earth-shaking change. In the special equipment diagram management, the use tradition cartography way and the information transmission method management unavoidably felt lacks the ability to do what one would like. Therefore, We unify with the advanced vector graph technology and the special equipment diagram management, develop special equipment diagram drawing software will have the vital significance.The primary intention of designing and development this software is to solve the question that special equipment diagram drawing simple, form unification and information sharing. In this software,the user take the text, the straight line, the curve, the circulararc, the rectangle, the ellipse, fan-shaped and so on the vector graphelement as a foundation, constructs the graph part by the level,passes through to the graph part migration, combination, rotation, shrink and enlargement, alignment, splicing, duplication, paste and so on operation, finally produces the special equipment diagram, and saves it into database or as graph element library. This software uses the text format to record vector graph, reduced the storage capacity, speeds up retrieval speed.In the article, drewing the Bezier curve and the table filling question in software has carried on the discussion, Elaborated based on Casteljau the algorithm Bezier curve questionsolution process, and designed, realized the corresponding procedure algorithm.This paper through carries on the comparative analysis to vector cartography software using the development three kind of forms, proposed integrates re-developments ways to suit the special equipment diagram drawing software the development, and controls the combination form by C#. NET + Visual Graph, chooses the Qi Lu petro-chemistry company pressure vessel examination center is the experiment site, develops special equipment diagram drawing software, realizes small two-dimensional vector graphics drawing software, the software realized the document creation, the graphic editor, the text sign note, the table management, the sheet management, the layer management, the sheet printing, the document saving, generate and reuse graphics element library integration special equipment vector graphics drawing. This software produces the special equipment diagram and graphics element library, saves as based on the XML graphics element characteristic data text format file, truely realizes graph vector.In investment movement period, at the operation simple, the movementhighly effective, the function is practical and so on the aspect, this software receives the widespread high praise from users.
