摘要
水产养殖池塘的野外天气环境复杂,应对其无线传感器网络系统节点供电的问题,本文提出一种稳定的、高精准度的太阳能供电系统。该系统由太阳能电池板、充电控制电路、稳压电路和锂离子电池组成,针对野外雷雨天气,系统设计了浪涌保护电路。允许太阳能电池板和外部5V直流输入对系统供电,通过无线MCU的数据采集与分析,可以根据优先级顺序,选择最合适的输入对无线传感器网络节点供电。无线MCU可以与数据中心通信实时传递电源工作情况。经过实验检测,本设计输出的电压5V与3.3V稳定、精度高,基本满足水产养殖池塘无线传感器网络节点的供电需求。
The field weather environment of aquaculture pond is complex and a stable and high precision solar power supply system is proposed in this paper in order to solve the problem of power supply at the nodes of its wireless sensor network system. The system consists of solar panel, charging control circuit, voltage stabilizing circuit and lithium ion battery. The system allows solar panels and an external 5 V DC input to power supply. Through the analysis of the data acquisition by wireless MCU, it can according to the priority order, chooses the most suitable for wireless sensor network node to supply input. The wireless MCU can communicate with the data center to transmit the power work in real time. Through the test, the output voltage of 5 V and 3.3 V in this design is stable and high in precision, which basically meets the power supply demand of the wireless sensor network node of aquaculture pond.
