摘  要：
为解决农田无线传感网络(WSN)中基于太阳能供电的Zigbee采集节点在连续阴雨条件下,因蓄电池供电不足造成无法长时间稳定工作的问题,研究了太阳能蓄电池剩余电量(SOC)与数据采集频率的关系。结果表明:相同工作时间内,采集频率越快,SOC越小,且二者成反比例关系。基于上述研究结果,提出了一种基于太阳能蓄电池的采集频率调控方法,即当蓄电池电量一定时,通过调节采集频率来维持节点的存活时间。试验证明经调节采集频率后,节点能在预期的时间内稳定工作。这可为WSN在农田环境监测中的应用提供技术支持,对农业物联网的发展具有重要意义。

摘  要：
In order to solve the problem of the inability of solar energy powered Zigbee acquisition node in farmland WSN( wireless sensor network) to work long stably resulting from the insufficient battery power supply in continuous rainy days,the relationship between SOC( residual battery capacity) and data acquisition frequency is studied. The experimental results show that in the same working hours,the greater the acquisition frequency is,the smaller the SOC is,and the two is in an inversely proportional relationship. Based on the above research results,this paper proposes a acquisition frequency control strategy based on solar energy storage battery. When the remaining battery power is constant,the node's survival time is maintained by adjusting the acquisition frequency. After adjusting the acquisition frequency,the node can work stably within the expected time,which provides technical support for the application of WSN in farmland environmental monitoring and is of great significance to the development of the agricultural Internet of things.
