基于ZigBee组网的智能家居安防系统

Smart Home Security System Based on ZigBee Networking

利用ZigBee技术实现了智能家居系统内部控制节点的组网,在此基础上,设计了一款智能家居安防系统。采用红外热释电传感器探测是否有人入侵,采用烟雾、燃气等传感器检测室内环境,如烟雾、一氧化碳等参数,通过ZigBee无线组网将各传感器信号汇总于主控制器,主控制器根据控制策略判断是否启动电话报警、开闭窗户等动作,从而实现家庭防盗、防火等安防功能。

Using ZigBee technology, the network of internal control node was achieved in smart home system. On this basis, a smart home security system was designed. The infrared hydroelectric sensor was used to detect whether there is a human intrusion. The smoke and gas sensor was used to detect the indoor environment, such as smoke, carbon monoxide and other parameters. Through the ZigBee wireless network, the signals of each sensor in this system were gathered into the main controller. According to the control strategy, the control decision was made by main controller, such as whether to activate the phone alarm, opening and closing windows and other actions. In this way, the anti-theft and fire prevention functions of smart home were achieved.
