摘要
综合ZigBee无线传感器网络和无线局域网(WLAN),设计了集多传感、分布式处理和事件触发监视于一体的具有双层网络结构的智能家居多媒体监控系统。ZigBee网络由标量传感节点和多媒体传感节点(网关)基于IEEE 802.15.4/ZigBee协议构建,负责采集标量数据上传到WLAN或执行来自上层的指令。多媒体传感节点基于WLAN连接到远程监控中心形成远程视频监控网络,将ZigBee网络上汇聚来的传感数据、报警信号和压缩视音频流等多媒体数据发送到监控中心及用户。利用此系统,为用户提供家居环境参数监测、报警、事件触发或持续的远程家居监控功能。
Based on the ZigBee and WLAN techniques, a smart home surveillance system with two network layers was designed, which employed multiple sensing, distributed processing and event-triggered surveillance. The ZigBee network layer was established on the IEEE 802.15.4/ZigBee protocol, constituting of scalar sensor nodes capable of capturing and transmitting scalar data to multimedia sensor nodes（gateway） or acting the control command from WLAN network. The video surveillance network layer constituted of multimedia sensor nodes connected by the TCP/IP protocol, which can transmit multimedia content, such as video and audio streams and the sensor/alarm data from the ZigBee network layer, to the monitor center or user. This system can provide the user with environment monitor, harmful events alarms, event-triggered or continuous remote surveillance of his/her home.
