摘要
针对ZigBee网络中节点能量有限,无法更换电池,因此降低功耗的问题,以一个监测温度的ZigBee网络为例,从硬件和算法入手研究如何降低传感器节点的功耗。硬件方面,各模块尽量采用低功耗芯片;所选芯片需具备多种工作模式,且切换方便;同时无线通信模块的选型要重点考虑其发送和接收数据时的能量消耗。而降低功耗的算法则含:状态切换、防冲突等。
The energy of ZigBee nodes in network is limited and it＇s not easy to change batteries, thus reducing energy consumption is a problem. Take temperature monitoring of ZigBee network as an example, research on how to reduce energy consumption of sensor nodes from hardware and algorithm. Low-power module chip is used on the hardware module; Chips to be selected should be multi-mode and switch conveniently; at the same time, focus on energy consumption of wireless communications module to send and receive data. And the algorithm of reduce energy consumption contains state switch and anti-conflict.
