摘　　要：针对传统变电站多媒体监控系统在灵活性、可扩展性等方面的不足,引入智能Agent技术,建立了基于Multi鄄Agent的分布式多媒体监控系统模型。该模型将传统监控系统的功能划分入不同的Agent工作组,通过各Agent之间基于消息机制的通信与协作实现恶劣条件下视频流的鲁棒传输,并使系统具有感知性、主动性和自适应性。分析了系统结构与工作原理,给出了Agent的功能模型,并对模型中数据压缩组和错误控制组中所分别采用的自适应快速运动估计算法及精细运动矢量场差错掩盖算法进行了介绍。分析表明,该模型的视频压缩和传输策略可随系统结点数目和通信模式的变化而动态调整。In order to overcome the shortcomings of traditional substation video monitoring system in flexibility and expandability,a model of remote distributed video monitoring system based on multi-agent is proposed. The functions of traditional systems are divided into different agent work groups. The communication and collaboration among agents realize the robust communication of video transmission with initiative,adaptability and apperception. The systematic structure and opera-ting principle are analyzed and the universal agent functional module is presented. The controllable predictive fast search algorithm for block matching motion estimation adopted in data compression group and the motion vector recovery algorithm adopted in error control group are demonstrated. Analysis results show that the proposed model changes its strategy of video compression and communication dynamically according to actual situation.
