摘要水是生命之源，是人类社会生产的重要资源。随着社会生产力的提高，人们对供水质量的要求不断提高。与此同时，工业废水的排放不断加剧了水源的污染，越来越多的水厂面临更加严峻的水质安全问题。64494

水厂水处理工艺流程复杂，随着水质要求的不断提高，传统的人工控制方式不仅效率低下，而且难以全面的保证供水质量。本文根据水厂水处理不同的工艺流程，主要采用泓格数据采集模块I-7017R、继电器模块I-7065D和转换模块I-7520分别设计测控模块，利用RS-485总线协议实现管理层与主控层的数据通信，并介绍了ZigBee技术解决无线传输的问题，最后介绍了运用国产组态王对各个模块组态的方法， 从而实现了水质监控系统的实时检测与控制。

Title    Design of Water Quality Monitoring and Control System for Waterworks Based on Distributed Module                      

Abstract

Water is the source of life and social production.With the improvement of social productivity, requirement of the quality of water supply is increasing. Meanwhile, the emissions of industrial wastewater are increasing pollution of water, more and more water plants face a acute problem of water quality and safety.

Water treatment technology in the waterworks is complex. With the increasing quality requirements, traditional methods of manual control are not only inefficient but also difficult to fully guarantee the quality of water supplies. According to differences of water treatment processes, this thesis mainly used Wang grid module which are manufactured by ICP DAS to design measuring and controlling module respectively, using RS-485 bus agreement to achieve the data communication between management layer and main controlling layer, and described how to use ZigBee technology to solve the problem of wireless transmission, finally introduced the method to using Kingview, thus to realize the real-time detection and control of the water monitoring system.
