摘要
设计开发了基于多媒体传感器网络的集多传感、分布式处理和事件触发监视于一体的智能家居监视系统。该系统基于无线传感网络和视频监控网络构建:前者由标量传感节点利用IEEE 802.15.4/Z igBee协议建立,负责采集、处理标量数据并传输结果到汇聚节点;后者则由多媒体传感节点利用以太网构成,将无线传感网络上汇聚节点的监控数据、压缩视/音频流等多媒体数据发送到监控中心及用户。测试结果显示,此系统能够较好地提供家居环境参数监测、用户危险事件报警、事件触发或持续的远程家居监控功能。
A smart home surveillance system based on multimedia sensor network was developed, which employed multiple sensing and distributed processing and event-triggered surveillance, This system consisted of the following two network layer： the wireless sensor network（WSN） layer was established on the IEEE 802.15.4/ZigBee protocol, constituting of scalar sensor nodes capable of capturing and processing scalar data and transmitting it to a sink node ; the video surveillance network layer constituted of multimedia sensor nodes connected by Ethernet, which can transmit multimedia content, such as video and audio streams and the monitor data from the WSN layer, to the monitor center or user. Experiment results show that the proposed surveillance system can provide the user with harmful events alarms, event-triggered or continuous remote surveillance of his/her home.
