Abstract：According to the problems of high fault rate ,poor speed regulation performances ,complicated operation ,high energy consumption and others existed in a control system of brine pump applied in a mine shaft freezing station ,the paper provided a plan that a PLC and frequency convertor applied to control the operation of the brine pump and a configuration software WinCC applied to timely monitor and control the working status of the system .The actual application of the freezing station to the mine ventilation shaft in Yangcun Mine showed that frequency conversion control system of the brine pump was high in automation and good in the speed regulation performance.The energy saving effect was re-markable and over RMB 90 000 of electric power fee could be saved in a month.
