摘要
为解决无线传感器系统供电受限问题,设计了一种基于压电效应的能量采集系统.该系统由能量收集模块、能量管理模块和无线传感模块组成.通过收集环境中的低频机械振动能量并将其存储到储能元件,实现为传感系统供电,其中能量管理模块采用升压芯片BQ25570,它将输入端电压升高至3.3 V并存储在储能元件为整个系统供电.实验结果表明,设计的无线传感器自供电系统能够在一定条件下实现能量的采集与利用,一定程度上延长了系统的工作时间.
Abstract
In order to solve the problem of limited power supply of wireless sensor system,an energy acquisition system based on piezoelectric effect was designed.The system consisted of energy collection module,energy management module and wireless sensing module.The low-frequency mechanical vibration energy in the environment was collected and stored in the energy storage element to achieve the purpose of supplying power to the sensing system.The energy management module adopted the booster chip BQ25570,which raised the voltage at the input end to 3.3 V and stored it in the energy storage element to supply power to the whole system.The experimental results showed that the designed wireless sensor self-power supply system could realize energy collection and utilization under certain conditions,and prolong the working time of the system to a certain extent.
