| Abstract: | In order to solve problems of poor reliability and lacking of visual and effective early-warning signal of traditional fault protection system of belt conveyor in coal mine,the paper proposed a design scheme of underground early-warning system of belt conveyor.The system adopts technologies of explosion-proof and intrinsic safety PLC and industrial field bus and realizes functions of linkage control of multi belt conveyors,fault monitoring and early-warning in forms of words and sound.The application result showed that the system is stable in running and strong in reliability,which improves efficiency of fault early-warning and treatment of belt conveyor. |
