摘要
通过分析CC2530的低功耗模式以及基于ZigBee协议的Z-Stack协议栈的休眠与唤醒机制,设计了一种基于CC2530的矿用无线传感器网络终端节点。采用基于福禄克万用表测量的实测方法,测试该终端节点的能耗,得出结论:终端节点与协调器建立连接时消耗的电流最大,在休眠与唤醒模式下电流消耗较小;终端节点的平均工作电流受发射功率影响较小;终端节点的休眠周期直接影响电流消耗,周期越长,则能耗越低。
By analyzing low power consumption mode of CC2530 and sleep or wake-up mechanism of Z-Stack protocol stack based on ZigBee protocol,a terminal node of mine wireless sensor network was designed which was based on CC2530.Energy consumption of the terminal node was tested through a measurement method based on Fluke multimeter.Conclusions are as following.Current consumption is the maximum when the terminal node establishes a connection with a coordinator,but smaller in sleep or wake-up mode.Average operating current of the terminal node is less affected by transmitting power.Sleep cycle of the terminal node directly affects current consumption,and the longer the sleep cycle,the lower the energy consumption.
