Title  Purification process monitoring device for urban water supply system design

Abstract Water is one of the most important factors in the development of human society。 With the development of economy and society, the demand of water supply is becoming more and more high。In order to improve the efficiency and quality of urban water supply, it is very important to optimize the purification process of urban water supply system, which puts forward higher requirements for the design of the monitoring device。

In this paper, through integrated refining the water treatment process, coupled with automation technology, to achieve real-time monitoring, quality and efficiency goals。 With water treatment process characteristics, selection of I-7000 series distributed intelligent module hardware circuit design, to use the software kingview to design monitoring interface, in the middle of the RS-485 bus protocol to achieve data communication between upper machine and lower machine, then the software and hardware debugging, system of urban water supply purification process monitoring device design is completed。
