摘要(Abstract)：
基于RFID环境监测物联网嵌入式传感器中转节点未考虑中转节点任务的合理分配问题,节点能量供应容易受到环境的干扰,导致采集的环境监测信息精确度较低,故设计新的环境监测物联网嵌入式传感器中转节点。采用传感器模块对中转节点数据进行采集和A/D转换等操作;通过MSP430F1611芯片的处理器模块,合理分配中转节点中的工作任务;通过无线传输模块完成中转节点数据的接收和传输,采用核心是LM1117芯片的能量供应模块为其他模块的运转提供能量支持。软件部分实现了中转节点数据采集、数据处理、数据包发送以及接收指令的工作过程。实验结果表明,设计的嵌入式中转节点对环境监测信息采集精度高、功耗低。
