Centralized control system for winch of mine hoister

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.
