The hoist is an important equipment for transporting materials underground and on the ground in coal mines,and the reliability of its electrical control system operation has a significant impact on safety production.At present,the coal mine hoist has been controlled by PLC and frequency converter,achieving automated operation.However,there are still some problems with the electrical control system of coal mine hoists,mainly reflected in incomplete monitoring and inaccurate fault diagnosis.In response to these situations,intelligent transformation was carried out on the electrical control system of the coal mine hoist to improve its performance.Research can provide certain reference for the transformation of the electrical control system of coal mine hoists.
