介绍了Raman散射型分布式光纤测温系统的原理,根据平煤股份四矿井下动力电缆的分布特点,采用KJ711矿用光纤分布式测温度系统实现了对井下动力电缆及巷道环境温度的实时在线监测。
The principle of Raman scattering distributed optical fiber temperature measurement system is introduced. According to the distribution characteristics of power cables in four coal mines of Pingdingshan Coal Mine, the KJ711 optical fiber distributed temperature measurement system is used to realize real-time on-line temperature measurement of underground power cables and tunnels monitor.
