摘　　要：通过软硬件结合的方式,实现以MSP430作为主芯片的可唤醒的无线传感器网络的雨量节点。设计以低功耗为前提,主要由MSP430F149、AT86RF212、ATA5282以及SL3型翻斗雨量传感器处理电路组成,利用DXP2004软件设计制作PCB板。传感器节点采用低频可唤醒芯片ATA5282地接收来自汇聚节点的低频唤醒信号,接收到正确信号时采集雨量数据并打包发送回汇聚节点。实验结果证明该雨量节点传输距离远、功耗低并且丢包率低。Through the way of the combination of the software and hardware to realize the can wake up wireless sensor network rainfall sensor node using MSP430 as the main chip. Designing with low power consumption for the premise, mainly constitutes by the MSP430F149, AT86RF212, ATA5282 and SL3 durable type of sensor rainfall processing circuit. Through using DXP2004 software, it designs schematic and products PCB. Sensor nodes use low frequency can wake up ATA5282 chip receive from sink-node of the low frequency signal awakening, when receiving the correct signal acquisition rainfall data, pack and send it back to sink-node. The experimental results show that the precipitation node distance transmission, low power consumption and packet loss rate is low.
