摘要
为实现果园土壤水分信息的长期可靠获取,使用超低功耗控制器MSP430F1222和微功耗无线射频收发芯片nRF905构成监测系统的无线传感器节点。同时,引入无线传感器网络的概念来适应果园面积广阔的特殊性和传感器配置灵活的要求。接收终端配备铁电非易失性RAM、液晶屏和按键,方便存储、查阅数据和参数设定。经过人工配土测试和果园现场运行,结果表明监测系统湿度的精度误差小于3%,且结构简单、功耗低、运行可靠,满足果园土壤水分监测的要求。
To achieve long-term reliable access to the orchard soil moisture information,the papers build wireless sensor nodes for monitoring system using ultra-low power controller MSP430F1222 and micro-power radio frequency transceiver chip nRF905.The introduction of the concept of wireless sensor networks to adapt to the special nature of the vast area orchards and sensor configuration flexibility requirements.Receiving terminal is equipped with nonvolatile ferroelectric RAM,LCD screen and buttons for storage,access to data and parameter settings.After artificial mixed soil testing and orchard site operation,results show that the accuracy of moisture monitoring system is less than 3%,and simple structure,low power consumption,reliable operation to meet the orchard soil moisture monitoring requirements.
