DCS通用仿真软件的研究

Research on general purpose simulation software for DCS

鉴于目前面向分散控制系统(DCS)操作员站的仿真软件缺乏开放性和通用性,研究、开发了以数据库为基础,采用面向对象的程序设计方法的DCS通用仿真软件,它运用可视化构件技术实现DCS仿真软件的通用化。该软件采用客户ˉ服务器的工作模式,按功能分为组态模块、实时驱动模块和网络通信模块。介绍了该软件的系统结构,阐述了各模块的设计思想及实现方法。DCS通用仿真软件已成功应用于发电厂仿真机的开发中,且效果良好。

In view of the fact that simulation software for operator stations of distributed control system (DCS) lacks openness and versatility,the databasebased general purpose simulation software for DCS is developed with the objectoriented method,the visual component technique used to enable the versatility of the software.Working in the client/server mode,the software is functionally divided as the graphic configuration module,the runtime driver module and the network communication module.The system structure of the software,the design idea and implementation method of the modules are expounded in this paper.The software is successfully applied to the development of power plant simulators and good results obtained.
