Abstract: For problems that manual control method of monorail turnout may lead to frequent switch of monorail and low transport coherence, a driver control system of monorail turnout based on PLC was designed. The system takes PLC as control core, realizes functions of rernote driver control and status indication of turnout and fault alarm, which insures security and continuity of monorail transportation and improves automation degree and efficiency of auxiliary transportation system of coal mine.
