无线传感器网络节点及其功耗测量平台设计

Designing measurement platform of wireless sensor network nodes and power consumption

针对青海高寒地区的特殊环境,为了更好地解决无线传感器网络节点的供电和续航问题,利用低功耗技术、太阳能光伏发电和混合储能系统,设计了一个光伏供电的无线传感器网络节点系统。其次,通过对无线传感器网络节点的功耗特点分析,基于微弱信号检测技术,设计了无线传感器网络节点功耗测量平台,并对所设计节点的工作、空闲和睡眠3个模式进行功耗测量分析实验。结果表明:无线通信模块的功耗最多,根据对所设计节点的功耗测量试验数据分析,验证了功耗测量平台的有效性和准确性。

Based on the special environment of the alpine region of Qinghai,a solar- powered wireless sensor network node system was designed for solving the problems power supply and battery life.Low- power technology,solar photovoltaic and hybrid energy storage system were utilized in the system to solve the power and endurance issues of wireless sensor network nodes. By analyzing the power consumption characteristics of wireless sensor network node,a measurement platform was designed based on weak signal detection technology. The power consumption measurement and analysis were carried out in the work,sleep and idle three models of nodes. The results show that the power consumption of wireless communication module is the biggest in the nodes. The validity and accuracy of the power measurement platform is verified by measuring the power consumption of the design node test data analysis.
