Abstract: In view of problem that there is not well communication among belt conveyors and related personnel cannot real-timely know production process of transportation system of belt conveyor in original control system of belt conveyor of a Coal Mine, the paper proposed a reform scheme of centralized control system of belt conveyor. The system takes ControlLogix PLC as core and uses iFIX configuration software to collect and monitor data of each belt conveyor under premise of no changing local control mode of original system, which realizes centralized control function for transportation system of belt conveyor by dispatching center. The actual application shows that the reformed system makes each independent electrical control system to be integrated in one system, which enhances coordination of belt conveyors and improves safety and reliability of device.
