多现场总线技术在污水处理控制系统中的应用

Application of Multi-Fieldbus Technology in Control Systems of Sewage Treatment

着重阐述了城市污水处理控制系统中几种常用的现场总线技术,分析了任何一种现场总线均不能覆盖所有应用面现状。提出了在多总线技术并存的情况下,实现数据交换的两种方案。经几家污水处理厂的实际运行表明,多现场总线技术的引入,提高了系统的灵活性、可靠性和综合自动化水平。

Several types of fieldbus technologies commonly used in urban sewage treatment control systems are mainly described.The current status and the fact of any type of fieldbus is unable to cover all kinds of applications are analyzed.Two strategies of data exchange under current situation of multiple fieldbus technologies are compatible.Through practical operations in some sewage treatment plants,it is shows that introducing multiple fieldbus makes the system flexible,reliable and enhances the level of integrated automation.
