Abstract: For problems of relay control mode used in winch of mine hoister such as simple protection, larger workload and so on, the paper introduced a centralized control system for winch of mine hoister which takes PLC as control core, takes integrated protector of motor as main protection device, and takes touch screen as human-machine interface. The system realizes functions of independent operation, synchronous operation, independent stop and synchronous stop of four winches of 16 t and two winches of 10 t operators, multi-protection of winch motor, and real-time display of winch parameters, which improves reliability of safe operation of winch and reduces labor intensity of operators.
