An Application of Fuzzy Control Based on PLC in Rubber Dam Monitoring System

In this paper, a rubber dam monitoring system is presented taking the rubber dam in Linyi, Shandong province as an example. SIEMENS PLC (Programmable Logic Controller) and fuzzy control which are used in the data acquisition unit of the system is to control the water level and the sluice with kinds of detection methods. The data exchanges between PC (Principal Computer) and PLC is implemented by WINCC to realize remote control. A fuzzy controller to control water level is introduced, which increases the accuracy of water level control greatly with advanced fuzzy control algorithm.
