摘　　要：针对现有视频监控系统无效信息多造成存储资源严重浪费的现象,提出了基于动目标检测的视频监控智能节点设计方案;利用微波移动传感器检测运动目标多普勒信号,通过微控器采集调理后的多普勒信号完成运动目标识别,并控制传输设备将含有动目标的视频监控信息和多普勒频率数据传输到监控中心进行实时处理;实验结果表明,视频监控智能节点最大探测距离可达15m,该设计有效提高了视频监控的有效信息,减少了存储资源,具有广泛的应用前景。A design scheme of an intelligent node control system based on moving target detection is presented to reduce the invalid information which is a waste to the storage resources in video surveillance system. The new scheme has made use of the microwave motion sensor module to measure the Doppler signalfrom the moving target. According to the conditioned Doppler signal, microeontroller completed the target recognition, and controlled the data transfer system to transmit the video surveillance signal and target Doppler data which contained moving target to the surveillance center for real - time processing. The experiment results indicate that the farthest detection range of intelligent node can reach to 15m, and the design can improve the valuable video surveillance information and greatly reduce the storage resources, and widely applied.
