应用于无线传感器节点的微小型复合能源收集系统

摘要

A prototype of composite energy generator applied in wireless sensor nodes was designed and implemented.Based on a wireless magnetic traffic flow sensor,the design target was defined.Solar energy,wind energy and strain energy were selected as the ambient energy source.According to the features of the three sources,energy management module and energy storage module were designed.The prototype was implemented and tested.The experimental results show that the prototype can continuously supply 50 mW output power at 3.55 V for 35 h.%设计并实现了一种可应用于无线传感器节点的复合能源系统样机,基于一种无线地磁交通流传感器,提出了本文的设计目标.选择太阳能、风能、应变能作为系统的能量源.根据这3种不同能量源的特性,对能量管理模块与能量储存模块进行了针对性设计,最后实现并测试了样机.实验结果表明,该样机可连续35 h在3.55 V电压下输出50mW的电能.
