摘　　要：针对输电线路外力破坏引起的跳闸事故频繁发生这一日益突出的问题,笔者提出了一种输电线路防外力破坏智能预警系统的整体构思,并在现场测试安装该系统运行良好。该系统以TI-TMS320DM6446芯片作为处理器,完成周边模块的配置以及视频监测系统的设计;采用高斯混合模型、背景差分和最小外接矩形等算法实现对云台摄像机捕捉的运动目标进行检测和标识,并给出预警信息。现场运行表明,该系统效果显著,实时性强,在防止输电线路外力破坏方面起到了积极的作用。To preserve the transmission line from frequent tripping accidents caused by external damage,an intelligent early-warning system was designed and implemented. TI-TMS320DM6446 was taken as its processor,combining with a peripheral module and a visual monitoring device. The Gaussian mixed model（GMM）,the background subtraction method and the MER method were used for moving target detection and identification, and the early warning information was hence given at the same time. Field test demonstrated the remarkable effectiveness and real-time performance of the system in preserving transmission line from external damage.
