摘　　要：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,实现DPU工作过程的模拟。其中,虚拟DPU算法块在Visual C++6.0高级编译环境中开发。该方法保证了DCS系统的仿真精度及准确性,又增强了系统的可移植性和可扩展性。This paper carries out the DCS distributed processing unit mathematical model simulation about Symphony distributed control system with a virtual DPU technique. This software transplants the real distributed control unit to virtual DPU, is disengaged from hardware equipment, and imitates DPU＇ s working process. The virtual DPU arithmetic blocks are developed with Visual C ＋＋ 6.0. This method ensures the accuracy and veracity of DCS system. Moreover this method tones up the transplantability and expansibility of the system.
