摘要
以CC2430芯片为核心设计一种用于温湿度测量的无线传感节点,为了降低节点功耗,在ZigBee协议栈的基础上进行改进,为传感节点设计了空闲、触发和主动等3种工作模式,使节点能够按照实际需求控制采样的时机和速率,以减少传感节点用于无线通信的能量开销,从而满足无线传感器网络对节点低功耗的设计要求,同时根据已知参数预测传感节点寿命,并通过实验进行了验证。
Wireless sensing node for temperature and humidity measurement was designed by taking CC2430 chip as a core. By improving the design of ZigBee protocol stack, sensing node can run in idle mode, trigger mode or active mode. The opportune moment and rate of sampling are controlled in accordance with actual demands, so as to reduce the node＇s energy consumption for wireless communication and to meet the low-power requirement of the wireless sensor network. The lifetime of sensing node is reckoned according to the known parameters. An experimentation was performed to validate the design,
