The remote monitoring system based on PLC and GPRS technology
Abstract:In this paper, the remote wireless monitoring system based on PLC, HMI and GPRS technology was developed, which is used in ZhongTie building. It describes the hardware modules, their principle and how to collect them. Then it analyzed the design of HMI interface, the communication protocol between HMI and GPRS and the development of remote monitoring system by using Labwindows.This system can acquirsite data by PLC then HMI will display it and GPRS module will transfer the data to the remote devices. This paper provides effective solutions for industrial control system
Keywords: PLC GPRS HMI Remote monitoring
