The Variable Frequency and Speed Regulation Constant Pressure Water Supply System Based on PLC and Fuzzy Control
For solving the problem of poor quality and waste of electric energy coursed by water supply mode of a high water tower and a direct water pump, introduce a constant pressure supply water system, which adopts embedded fuzzy control technology, using PLC and frequency convener as its core. When the system runs, water pressure of the pipe is inputted into the PLC from terminal X0 through pressure transmitter. Comparing the value of measured pressure with its set value, PLC controls the work frequency of the frequency converter by the output signal on fuzzy calculation in order to control rotation speed of water pump and adjust water pressure of the pipe. The real time control performance to the water Pressure of water supply system designed in this paper was proved to be all-right according to the experimentation validated. The hard ware module is steady-going and reliable, and the fuzzy controller is proper and valid and can guarantee the better stability of water pressure.
