基于Web的化工塔设备CAD系统的研究
摘要
化工塔设备的是化工、石油工业中最重要的设备之一。化工塔设备的参数化绘图系统的开发,对于整个化工机械行业的发展具有重要意义。本文根据当前CAD技术发展的新成果,研究了网络CAD技术,分析了网络CAD系统的体系结构,并据此设计开发了基于Web的化工塔设备CAD绘图系统,详细地探讨了系统实现的关键技术。本文的主要成果与特色如下:
1.基于Web的CAD系统的研究。从网络CAD特点出发,探讨了网络CAD系统实现的关键问题,结合网络CAD系统的设计需求,详细讨论了网络CAD系统的实现方案,并在此基础上提出了基于Web的三层B/S框架结构,同时对系统进行了功能设计,划分了系统功能模块。在本系统中,利用ASP.NET数据验证、数据传递和数据库操作等功能构建系统站点,实现系统远程访问和设计参数处理。
2.ObjectARX对化工塔设备的开发。在比较多种二次开发工具的基础上,选用ObjcetARX2006作为本系统AutoCAD二次开发工具,探讨了ARX开发环境配置、基本程序结构、图形数据库操作和数据库访问接口等问题,开发了一系列ARX功能函数,并进一步实现图形绘制。并将所绘制图形以DWF格式输出,实现在网页中调用。
3.模块化、参数化的设计。整个系统贯穿着模块化、参数化的设计思想。考虑到系统的复杂性和可扩展性,项目针对塔设备各个部件开发了相应设计模块,降低了系统的开发难度,缩短了项目开发周期。通过对设计参数的分析,
Chemical towers are one of the most important equipments in chemical and oil industry. The development of parameterized system for chemical towers plays an important role in the whole chemical machinery industry. According to the currently new achievement in CAD, web-based CAD technology is researched and its structure is analyzed. Hereby the CAD drawing system of chemical towers based on Web is developed . And the key technology of the system is discussed in this paper in detail. The chief achievements and features of this paper are:1. CAD system based on Web. In response to the characteristics of web-based CAD, the key problem is discussed. Combined with the requirement, the implementation of the web-based CAD system is detailedly reported. And three-tier B/S structure based on Web is put forward. The functions are designed and the modules are divided. In this system, remote access and designing parameter disposal are realized because the system website is built by making use of ASP.NET validator controls, data transfer and database operation, etc.2. Chemical towers are developed with ObjectARX. After comparing with several CAD advanced developing tools, ObjectARX2006 is chose in this system. ARX programming environment configuration, basic program structure, graphics
database control and database calling interface and so on are discussed. A series of ARX functions are developed and graphics drawing is achieved. The drawing files are output as *.DWF so that it could be invoked in web pages.3. Modularized and parameterized design. The thoughts of modularization and parametrizing are throughout this system. In view of complexity and expandability, the modules are designed correspond to each parts of a chemical tower so as to reduce the developing difficulty and shorten the project cycle. By the analyses of design parameters, the chief structural parameters are screened out, by which parameterized design can be implemented with engineering database.4. Database technology. Engineering database is set up according to the requirements in order to store design datum and design projects. The modules of data query and modification are developed to maintain and manage engineer datum. ADO is chose as the data access interface based on comparison with many interfaces.5. COM technology. Analyzing the characteristics of COM, the COM register and calling in ASP.NET pages are researched. Then ASP.NET can communicate with AutoCAD by COM.6. Multi-programming technology. In the development process, different programming languages are used in different modules. For example, in parameter input module, ASP.NET page logic is dealt with VB.NET and in drawing module, drawing function is implemented with VC.NET. The system can be developed with great efficiency because several languages can be brought into play in theirs most superiority.The development of CAD system of chemical towers based on Web aims at the requirements of parameterized design with the thought of web-based CAD. It is very important to improve the design level, shorten the design cycle and enhance the competitive power of enterprises so that it is worthy of popularizing in production.
