Design of Remote Environmental Monitoring System

Abstract:

A remote environment online monitor system was designed to replace traditional environmental data monitoring systems,which collected monitoring data manully and whose monitoring effects were not ideal.Field data can be collected and restored by Siemens S7-200 PLC,and the realtime data of equipment’s state can be sent to the host computer automatically through the GPRS DTU,and receive the host computer’s instruction and send the history data within a specific time.The host computer receives and processes the data of remote terminals with the Winsock control of VB6.0.This system is applied to Nanhai District of Foshan City to improve the efficiency of environmental regulation.
