污水处理厂现场总线的抗干扰问题

近年来,总线技术的应用越来越广泛,有效地提高了生产效率。但是,现场级测控系统的工作环境比较复杂,尤其是系统周围的电磁环境对系统的可靠性与安全性构成了极大的威胁。该文分析了干扰的影响,阐述了形成总线干扰的原因和抗干扰措施,从软、硬两个方面给出具体的解决方法。

Anti-interference of Field Bus in Wastewater Treatment Plant

The application of the bus technique is more and more widely to efficiently enhance the production efficiency. But the working environment of the field measuring and control system is more complicated, especially the electromagnetic environment surrounding the system constitutes the great threat on the reliability and safety of the system. the article analyzes the interference influence, sets forth the cause forming the bus interference and the anti-interference measures, and gives the detail solving methods from two soft and hard aspects.
