摘 要: | 无线传感器网络的传感器节点主要依靠电池供电,为保证节点能较长时间地稳定工作,对电池的供电性能具有较高的要求。本文作者组建了一个基于ZigBee协议的节点功耗测试网络,提供了一种基于WSN的电池电压在线监测的方法,测量误差范围在1%左右,分别对镍氢电池和太阳能电池供电性能进行了测试。实验结果显示,在数据采集周期为2s~600s的情况下,用普通镍氢电池为WSN节点供电只能维持其正常工作10天左右;而使用2000mAh锂电池搭配0.7W太阳能电池板对传感器节点进行供电时,可以维持节点长时间工作,本文的工作可以为今后节点电源设计和节点生存时间估计提供参考。

Abstract: | Sensor nodes of wireless sensor networks rely mainly on battery power, to ensure the nodes can work stably for a long time, battery power supply performance has higher requirements. The authors has set up a network based on ZigBee protocol to test the power consumption of sensor nodes, it has provided a method of on-line monitoring the battery voltage based on WSN, the measuring error scope at about 1%, then the performance test of Ni-MH batteries and solar battery-powered has been done. The experimental results show that, when the data collection period is from 2 seconds to 600 seconds, using ordinary Ni-MH battery for WSN nodes power supply can maintain its normal work 10 days or so ,while use 2000mAh lithium battery with a 0.7W solar panel powered sensor nodes, you can maintain the nodes to work for a long time. The work of this paper can provide a reference for the next node power supply design and estimation of survival time. |
