摘　　要：针对煤矿输煤系统设备多、位置分散、设备之间连锁关系复杂、设备运行环境恶劣等特点,采用PLC控制输煤系统可以有效地解决这些问题。为了提高系统的可靠性,采用双网双冗余的网络方式,并辅以IFIX组态软件实现上位机的在线监控。实践表明,该方法提高了系统的可靠性,保障了皮带运输机有序、稳定运行,提高了工作效率,降低了运行维护成本。Considering the particularity of the coal handling system, such as numerous and dispersed equipment with complex linkage relationship, and harsh operational environment, etc. , to effectively solve these problems, PLC is adopted for the coal handling system. In order to improve the reliability of the system, the dual redundant network method is used; and the online monitoring is realized with IFIX configuration software in host computer. The practice shows that this method improves the reliability of the system; ensures the belt conveyors working orderly and stably, and enhances the operating efficiency, reduces operation and maintenance costs.
