| 摘要: |
| 传统虚拟分布式控制系统(DCS)中的人机界面开发工作量大、逼真度不高,且不易修改。结合600MWSiemensTXPDCS仿真项目,根据组件对象模型(COM)设计思想,通过运用Microsoft提供的ActiveX控件技术,对虚拟操作员终端(VOT)人机界面进行了全新开发,分图形文字、操作/指示窗口、曲线和报警等进行设计,并例举了典型的动态元素分类。根据OPC规范,利用OPC客户端的4个属性值和方法函数与OPC数据服务器相连,进行数据交换。用VC 语言开发测试VOT主程序,并详细描述了其步骤。 |

| Abstract: |
| The workload of HMI(Human-Machine Interface) development in the traditional virtual DCS(Distributed Control System) is heavy,while its fidelity is low and the modification is difficult.With the design concept of the COM(Component Object Model) and the ActiveX control technique of Microsoft,the HMI of the VOT(Virtual Operator Terminal) for a 600 MW Siemens TXP DCS simulation system is developed in graphical words,operation / indication windows,curves and alarms.Typical dynamic element classifications are listed.According to OPC(OLE for Process Control) protocols,clients interconnect and exchange data with the OPC server through four attributes and method functions.The main program of the VOT is compiled and debugged with VC ,and development steps are described. |
