双路信号传输在矿井安全监测系统中的研究与应用

摘要

In order to improve the inspection period of mine safety monitoring system, the underground monitoring sub-station in Xu chang coal mine is divided into two large areas, install an independent signal transmission line in each area. Two signal transmission lines are gathered to the ground safety monitoring center computer room. Through the transmission of the dual signal transmission, the security inspection cycle of the system is reduced, and the real-time performance of the system is improved, and the safety performance of the system is enhanced. At the same time, the cost of system transformation is less, the maintenance is simple, the structure is reasonable and economical.%许厂煤矿为提高矿井安全监测系统的巡检周期,把井下监控分站分成两个大片区,每一片区独立安设一路信号传输线路.两路信号传输线路都汇聚到地面安全监测中心机房.通过双路信号的传输,监测系统安全巡检周期缩短一半,提高了系统对监测数据的实时性,增强了系统的安全性能.同时系统改造费用投入较少,维护简单,结构合理经济实用.
