Design of intelligent building environmental monitoring system based on ZigBee

为了实现节能、可靠的楼宇环境监测,提出了一种基于混合式拓扑结构的ZigBee无线网络系统,设计了以无线射频芯片CC3430为核心的传感器节点,使用阈值触发和休眠机制实现了节能,并对终端节点的电池使用时间进行了估算。实验结果表明,该楼宇环境监测系统的通信可靠,节点功耗低,能满足长时间工作的要求。

Aiming at robustness and energy conservation of intelligent building environmental monitoring,an ZigBee wireless network system using a mixing topology structure was presented.The sensor node was designed on the basis of RF CC2430.The energy-saving was achieved by mechanisms of threshold-values trigger and node sleeping.The battery using time of terminal node was estimated.The test results indicate that,depending on low-power nodes and stabilized communication this system can meet the requirement of long time stable working.
