火电厂集散控制系统仿真中虚拟DPU的实现

The Design and Exploitation of the DCS Simulation Software Based On Virtual DPU Technology

采用虚拟DPU技术对Symphony集散控制系统实现了DCS分散处理单元数学模型的仿真。该软件将实际分散控制单元中的DPU功能移植过来,脱离了硬件设备,采用软件仿真实现DPU工作过程的模拟。其中,采用模块化设计思想,运用面向对象技术,以VisualC++6.0为开发环境。该软件以静态链接库(LIB)的形式,将所有功能码的数据和算法封装以供仿真程序调用,实现软件复用和维护简单功能。

Adopted a virtual DPU technique carry out the DCS distributed processing unit mathematical model imitation about Sym- phony distributed control system. This software transplanted the real distributed control unit to virtual DPU.It disengaged hardware e- quipment and adopting software made the processing about the real DPU＇s working come true. The author make the use of Object-- Oriented program design technology and applying the thought of modularization designing to realize this software in the environment of Visual C＋＋ 6.0. In this software.all of the function codes data and functions have been encapsulated as the form of static Lib in order to not only gain the ability of software reuse and facility of maintenance but also supply a use to the main simulation program.
