The Research of Network-Based Remote Monitoring Systems in the Scattered Site

Abstract:

With the exaltation of the function and the performance of the PLC technique, the application of the industry control network become more and more universal. Particularly In the application whose geography location is scattered and the stand is numerous, it can raise the Networked level completely by a control system renovation. This text mainly introduced PLC network technique which uses PLC as core controller, and makes use of existing telephone network and modem of business as communication line. It enables us to achieve active and passive communication between the master computer and the PLC slave. It focused on solving the call between the PLC and the modem. Finally, it realizeed fully automated monitoring of heat exchanger and water pump station.
