为了满足水厂加氯和加氨工艺安全性的要求，采用RSview 组态软件开发人机操作界面，以实现对水厂加氯、加氨系统的监控。本文特别说明了该人机界面的功能和特点。实践证明该人机界面设计合理，界面友好，较好的满足了生产的需要。关键词：人机界面；加氯；加氨；RSviewAbstract: For the sake of the security of Chlorine dosing and Ammonia dosing technics in water plant, RSview configuration software is adopted to develop HMI（Human Machine Interface）, which carries out the supervision and control of the Chlorine dosingand Ammonia dosing system. This paper especially introduces the functions and characteristics of the HMI. Result shows that thedesign of the HMI is reasonable and friendly, and the need of production is fulfilled.Key Words: HMI; Chlorine dosing; Ammonia dosing; RSview
