基于光纤传感器的煤堆温度监测及预警

Temperature Monitoring and Early Warning for Coal Stack Based on Optical Fiber Sensor

煤堆自燃会造成巨大的经济损失和严重的环境污染,利用光的拉曼散射原理,设计了针对煤堆的分布式光纤温度监测系统,由测温主机、传感光纤和温度监测软件3部分组成。具有灵敏度高、可靠性好、不受电磁干扰影响等特点,可用于煤堆各处温度的监测,并能在温度达到自燃条件前提早发出预警,为避免自燃现象的发生提供条件。

Spontaneous combustion of coal stack will cause huge economic losses and serious environmental pollution. A distributed fiber optic temperature monitoring system is designed for coal stack based on Raman scattering principle, consisting of three parts of the host of temperature, the sensing fiber and temperature monitoring software. With high sensitivity, good reliability, and not affected by electromagnetic interference, it can be used for the monitoring of the temperature of the coals throughout, and issued a early warning to avoid the occurrence of the phenomenon of spontaneous combustion.
