摘要
无线传感器网络中节点的能量是一种非常有限资源,考虑到低功耗实现的三个主要解决方面,设计并实现了一款低功耗的数字远传燃气表节点,提出了节点的节能设计要点,给出了各个模块的具体设计。理论计算和实验表明:本文的低功耗设计可以使燃气表节点的使用寿命提高至3～5年,极大程度的满足了燃气公共事业计量抄表的应用需要。
Low-power design of motes is critical in wireless sensor networks.We consider three main aspects of low power consumption and design and implement the mote for remote gas meter reading.This paper describes the main energy saving methods and the modules of implementation in details.The simulation and experiment results show that our design can extend 3~5 years of the battery lifetime for gas meter thus it fulfills the application requirement of the gas utility reading system.
