远距离检测瓦斯的光导纤维目前，探测瓦斯聚积一般使用远距离监测器，但大多数监测器依赖于无本征安全的电源。万一断电，监测器就得依靠暂时备用的蓄电池组工作。蓄电池的电能一旦用完，监测器就失去作用，形成一个潜在的危险局面。美国矿业局的研究人员们找到了一种不用... Optical fibers for long-distance gas detection At present, long-range detectors are commonly used to detect gas accumulation, but most monitors rely on power supplies that are not intrinsically safe. In the event of a power outage, the monitor has to rely on temporary backup battery packs. Once the battery power is exhausted, the monitor loses its effect, creating a potentially dangerous situation. US Bureau of Mining researchers have found a need not ...
