基于PROFIBUS集散控制系统的设计研究

Design and Research of Distributed Control System Based on PROFIBUS

通过分析集散控制系统的不足,提出了在现有集散控制系统基础上融入PROFIBUS的实现方案。根据集散控制系统和PROFIBUS的技术特点,给出了系统的分层体系结构。设计了一种基于PROFIBUS的集散控制系统,详细描述了过程I/O层的网络结构,并分析了系统的实时性、可靠性和经济性等参数指标。这对于解决传统的集散控制系统的不足和实现火电厂的全面信息化有重要的借鉴意义。

The limitation of distributed control system (DCS) in power plant is analyzed. Realization project of this system is to inte- grate PROFIBUS into DCS. Layered system structure is put forward according to the characteristics of DCS and PROFIBUS , and a type of distributed control system based on PROFIBUS is designed . Network structure in process I/O control layer is focus on. Index of real time, reliability and economic is analyzed. It is important for power plant to solve the hard problems that exist in co...
