摘要
电池供电的无线传感器网络节点在电量不足时,节点上的有源器件不能稳定工作。基于网络节点中的CC2430/31芯片,在Zig Bee协议栈中添加定时功能,使以电池供电的节点能够周期性地采样电池电压并进行判断,当电压低于预先设定的报警低限时,利用LED灯的闪烁进行报警。同时该节点进入非正常工作状态,断开与网络的联系,以保证其他节点交互信息的可靠性。
When the electricity shortage appears on the wireless sensor node powered by the batteries,the active device can't work stablely.Based on CC2430/31 chip in the network nodes,timing function is added in the Zig Bee protocol stack to make batteries-powered node periodically sampling battery voltage and judge.When the voltage is lower than the default alarm low limit,LED light will flink to alarm.At the same time,the node will not communicate with network to ensure the reliability of the mutual information of other nodes.
