煤矿电缆火灾自动监控系统设计与实现
|
摘要
为了解决煤矿井下电缆火灾自动探测与灭火的问题,采用理论分析和实验的方法,研究了一种分布式光纤测温与ZigBee通讯控制的超细干粉灭火技术相结合的煤矿电缆火灾自动监控系统。在依兰煤矿进行的应用实践表明,该系统采用光纤自发拉曼(Raman)散射效应与光时域反射(OTDR)技术可以实时准确探测煤矿电缆不同位置的温度并定位火灾位置,通过ZigBee无线通讯网络控制灭火装置快速自动处置。该成果突破了煤矿电缆火灾点式监测及不能快速自动灭火处置的传统模式,可以有效防止煤矿电缆火灾发生。
In order to solve the problem of automatic detection and fire extinguishing of cable fire in coal mine,a coal mine cable fire automatic monitoring system is studied by using theoretical analysis and experimental methods combining distributed optical fiber temperature measurement and Zig Bee communication controlled ultra-fine dry powder fire extinguishing technology. The application practice in Yilan Coal Mine shows that the system can accurately detect the temperature of different locations of coal mine cables in real time and locate the fire location by using optical fiber spontaneous Raman scattering effect and optical time domain reflectance(OTDR) Technology,and control fire extinguishing device for quick and automatic disposal by using ZigBee wireless communication. The achievement has broken through the traditional mode of point-type monitoring and non-rapid automatic fire extinguishing disposal for coal mine cable fire,which can effectively prevent coal mine cable fire.
