供水系统自动监控的研究与应用

THE RESEARCH AND APPLICATION ON AUTOMATIC MONITORING OF WATER SUPPLY SYSTEM

对供水系统的上位机监控系统进行设计,硬件选择了西门子公司S7-200型号的PLC对供水系统水泵进行控制,供水系统的水泵采用变频器进行变频调速。运用组态王软件实现上位机监控程序,将STEP7/WIN软件编写的可修改的供水系统控制程序下载到PLC中运行。该设计在保证生产生活用水的同时大大降低了劳动强度和成本。

Designed the upper computer monitoring system for the water supply system. In the design, it chooses Siemens PLC S7-200 to control the water pump in the system, and use frequency changer to control frequency of the pump. It takes kingview software to relize the upper computer monitor program. Then to run the water system control program writed with STEP 7/WIN which is revisable. The design can ensure the production and living water, in the same time, it can decrease labour strength and production cost.
