摘要
随着物联网行业的不断发展,越来越多的无线传感器的监测网络设备得到应用。基于此,文章设计了一款太阳能供电系统,为野外的传感器节点提供电源,并将数据上传。系统采用STM32L0作为供电系统的主控芯片,CN3791电池充电管理集成电路,以太阳能电池板和锂电池为系统供电装置,可以根据光照强度灵活选择太阳能电池板或锂电池供电,以NBIoT为通信设备,用于与云平台通信,监测系统的状态。实验结果证明,系统符合设计需求,具有一定的实用价值。
With the continuous development of the Internet of Things industry,more and more wireless sensor monitoring network devices have been applied.Based on this,this paper designs a solar power supply system to provide power for sensor nodes in the field and upload data.The system uses STM32L0 as the main control chip of the power supply system,CN3791 battery charging management integrated circuit,solar panel and lithium battery as the system power supply device,which can flexibly select solar panel or lithium battery power supply according to the light intensity,and NB-IoT as the communication device,which is used to communicate with the cloud platform and monitor the status of the system.The experimental results show that the system meets the design requirements and has certain practical value.
