摘　　要：针对常规煤矿带式输送机故障保护系统可靠性较差、缺乏直观有效的预警信号等问题,提出了一种煤矿井下带式输送机预警系统的设计方案。该系统采用隔爆兼本安型PLC及工业现场总线技术,实现了多级带式输送机的联动控制、故障监测、文字语音预警等功能。应用结果表明,该系统运行稳定,可靠性强,提高了带式输送机的故障预警及事故处理效率。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.
