GPRS-Based Remote PLC Multi-Parameter Monitoring System

Abstract:

This paper analyzes the status and problems of domestic water quality monitoring, and presents a controlling system,that takes the PC as monitoring computer and Siemens S7-226 programmable logic controller (abbreviated PLC) as the terminal equipment, to realize wireless transmission of data and instructions via GPRS communication module. Also it elaborates water quality parameter monitoring systems hardware and software implementation. The result shows that the system is stable and reliable, and method is easy for operator to grasp. Through real-time monitoring and controlling, the result shows that its value is stable, achieves the intended purpose. It provides a practical way to improve china's water environment.
