In order to decrease the energy consumption of pumping station and improve the operation efficiency of pump unit,an automatic control method of pumping station based on mean shift algorithm and PLC technology is proposed.Firstly,the components of pumping station are analyzed,and the basic parameters that can affect the working performance of pumping station are determined.Then,the mean shift algorithm is used to track these basic parameters for determining the operation situation of pumping station,and the automatic control model of pumping station is established.Finally,the PLC model is selected,and the fuzzy automatic controller of pumping station is compiled through the PLC programmable controller function to realize the automatic control of pumping station.The example test results show that,compared with the original operating conditions of the pumping station,the power consumption of per ten thousand m^(3)of water withdrawal is reduced by 90.7,33.5,77.9 and 68.1 kW·h respectively,and the efficiency is increased by 2.9%,2.2%,4.7%and 14.23%respectively.
