本文对煤矿井下监测分站的设计进行了讨论 ,提出了低功耗设计方案 ,低功耗不仅减少电费开销 ,它还将导致一系列适合井下环境的优越性。首先减小甚至取消笨重昂贵的电源箱 ,减少分站体积 ,便于安装 ,便于维修 ,极大地减少了设备费用。其次低功耗的设计将使系统抗干扰能力大大加强 ,提高了设备的可靠性。本文还介绍了软、硬件的设计思想和方法 In this paper, the design of coal mine monitoring sub-station is discussed, and a low-power design scheme is proposed. Low power consumption not only reduces the electricity bill, but it also leads to a series of superiorities for underground environment. First of all, reduce or even cancel the heavy bulky power box, reduce substation size, ease of installation, ease of maintenance, greatly reducing the cost of equipment. Second, low-power design will greatly enhance the anti-interference ability of the system and improve the reliability of the equipment. This article also introduced the software and hardware design ideas and methods
