一种新型煤矿井下传感器供电方法研究

A new method of power supply for sensors in underground coal mine

为克服矿井复杂危险环境下传统的传感器供电方法的缺点,提出了一种新型的供电方法。该方法以激光作为能量载体、光纤作为传输媒介,通过光电转换技术,实现传感器的远距离供电。完成了光纤内能量与信息并行传输的仿真研究,验证了光纤内能量与信息并行传输的可能性;完成供电系统部分实验装置设计,实现了光纤的远距离供电。

In order to overcome the disadvantage of the traditional power supply method in the complex hazardous environments,a new type power supply method was proposed,which used laser as energy carrier and optical fiber as transmission to achieve the long distance power supply. A simulation was completed on optical fiber parallel transmission of energy and information,and possibility of the parallel transmission was verified. Experimental facility of the power supply system was designed to achieve a long-distance fiber optical power supply.
