The Design And Implementation Of Electronic Approval System In Constructive-detailed Plan

By the number of urban construction has increased dramatically,the volume of examination and approval for the planning acceptance department is growing.In order to solve the weak links and legacy issues in the approval process,it has developed a “design-establish-examine-approval” integration of electronic approval system in Constructive-detailed Plan.This is not only the inevitable trend of information management of planning industry,but also the power engine for the development of land and resources information.At present,there is a lot of problems of the electronic approval from demand research to the whole process of design and achieve.For example,how to apply information data specification of planning and construction industry to the electronic approval system,how to coordinate the design department and the approval departments by using the electronic approval system,and how to combine the AutoCAD for secondary development of electronic approval system,etc.According to the current situation of architectural design unit and the approval departments,the paper firstly analyzed the traditional planning approval process and business requirements,then combined with the development history and the remaining technical issues of electronic approval system,to analyze on various aspects of the functional requirements of electronic approval system deeply.Besides that,compared several way of secondary development of electronic approval system,it chooses.net API interfaces and extension of the data model eventually,and develops electronic approval system in Constructive-detailed Plan for the best aided design and approval,which implements the electronic acceptance and approval to constructional drawings,and achieve the requirements of automation,efficiency,standardized,transparent,and authoritative.The electronic approval system uses the.net to exploit the function of plug-in,and puts the design assembly into the AutoCAD software that assist users to electronic approval,which combined with convenient and flexible custom interface.The arranged module of the electronic approval system translates the drawing entities into the entities of conforming to the strict design standard and taking standard additional data.The examination and approval module could detect,handle,and complete drawings technical review,also read the data,and automatically present the important design data.After approving,the storage module of the electronic approval system keeps the data results to the sde database of arcgis,and save the electronic data to the file.The electronic approval system is a secondary development of AutoCAD,which uses the method of AutoCAD.net API technology to develop a winform class library,using the.net Framework as programming model,C# as programming language,visual studio 2010 as the development tools.The traditional interface-business logic-data structure as the basic framework.By register a series of CAD command,to realize the function of the system design.All operations of the electronic approval system are using dwg drawing in the environment of CAD environment,and all data save in it,so data frame of dwg drawing is the data frame of the electronic approval system,which is safe and reliable.
