摘要
结合校园防火报警需要,设计了基于ZigBee技术的无线校园防火报警系统。该系统以意法半导体公司推出的STM32系列ARM控制器、TI公司的CC2420无线射频芯片为核心,对无线传感器网络中的终端节点、路由器节点、协调器节点的硬件和软件进行了模块化设计。传感器节点以温度、烟雾和CO浓度为实现监测对象,判断是否有火灾隐患,从而实现校园防火报警系统的无线网络化。
In this paper,a fire alarm system for campus based on ZigBee wireless network was designed,which can meet the campus＇ fire alarm management. This system takes ST＇s STM32 microprocessor and TI＇s CC2420 RF chip as the core. The fire alarm system adopts the modular design to design the hardware and software of the terminal node ,routing node and sensor node according to the function setting in wireless communication network.The sensor sub-nodes can detect temperature ,smoke or carbon monoxide signals real-time captured by the sensors and determine whether to have fire hazard. Thus it realizes the wireless network of fire system for campus.
