视频监视系统通过提供水利工程及相关区域的实时视频数据,以辅助水利部门抗洪防汛和水资源调配.基于Zigbee无线通信技术的优点,提出了一种适合水利工程的基于Zigbee的视频传感器网络构架,在此基础上设计并实现了基于Zigbee通信协议的视频传感器节点和基于CDMA通信方式的汇聚节点.视频传感器节点通过CMOS摄像头采集环境事件的视频信息,然后利用无线Zigbee多跳方式将视频数据传输到汇聚节点,汇聚节点通过CD—MA移动通信与控制台或监控手机通信.
Video monitoring system is supposed to provide real-time video information on water conservancy engineering and related region for water conservancy manager to make decision. Thanks to the development of wireless sensor networks, video sensor networks has become one research hotspot. Based on the strongpoint of Zigbee wireless communication technology, this paper puts forward a truss of video sensor network based on Zigbee for water conservancy engineering, moreover, the video sensor nodes are designed and realized based on Zigbee communication protocol, as well as sink nodes based on CDMA communication manner. Video sensor nodes gather video information from surroundings through CMOS camera, then transmit video data to the sink node by Zigbee multi-hop transmission manner. The sink node communicates with console through CDMA Mobile communication.
