S组态软件。 论文首先研究了集散控制系统及其组态软件的概念和基本功能,分析了.NET 核心技术以及采用.NET开发组态软件的优势。其次详细分析DCS组态软件的层 次,DCS组态软件分为组态层、运行层和管理信息层,设计了采用XML作为各 层次接口的组态软件体系结构。最后,根据功能模块划分,分别介绍了数据库组 态模块、通信模块、界面组态模块和控制回路组态模块采用的技术和具体实现。 论文采用了XML技术,进行数据库组态模块的设计,解决了异构数据库及 实时数据结构标准不统一的问题,并设计了以XML文件表示的全局点目录。论 文采用了OPC技术,进行通信模块的设计,解决组态软件与硬件兼容的问题,并
在.NET环境具体开发了OPC客户端接口。论文研究了控制回路组态技术,按照
IEC61131—3标准采用功能模块图形组态的方式设计开发了控制回路编辑、控制回 路组态编译和文件保存三大模块,实现了控制回路的图形组态。论文最后设计了 组态软件的图形界面及其生成系统。在.NET环境下使用GDI+技术采用矢量图元 方法开发实现了静态画面组态编辑器,在此基础上实现了动态画面的生成;采用 水晶报表与Excel相结合的方法实现报表的生成与打印。

基于.NET的DCS组态软件研究与设计
Abstract
In the market has many DCS configuration software which developed by the VB,
Delphi
or
C++.In recently the DCS configuration software
request opening and
network,it must has perfect interface from the DCS configuration software to the upper formation software and the hardware,has based registration
as
on
the network data point it’s need the.NET the more has many
well
as
the report and the
form
corc
printing function.So technology.Because
as
adaptive developing plat
advantage to developed the Configration—software,such
spans the language and the
plat,easy to using the technology of XML to implement the compatibility between the DCS Configration—software with the ERP and MIS software,easy to developed the report forms and using the he technology of GDI+tO implement the graphics’editor, adapted well to developed the opening and the informational Configration-software, this paper discussed how to develop the DCS developing plat and the
core
Configration—software by the.NET
technology.
Fist introduced the distributed control
system(DCS)and
the DCS Configration
software,expounded the main technology of the.NET and the advantages of the.NET
to developing
the Configration—software.Secondly analyzed the DCS Configration
software three layers and discussed the new configuration software’s system structure which.is using the XML
as
the interface between the layers.Third according to the structure,introduce the technology and the model,the communication model,the
new configuration software’s system implement of the configured
database
configured interface model and the configured control’s loop model. The configured database model used the XML technology to solve problems such
as
the disunity standard of the database structure and the isomerism database.The
communication model used the OPC technology to solve the
