Abstract： An intelligent video monitoring alarm algorithm based on time series combinational logic operation is proposed to improve the identification and alarm of multiple targets in video monitoring of smart community. In order to realize the cooperative work of multi?cameras and multi?triggering events， and complete the detection， tracking and analysis of targets， the operation rules of combination logic， such as logic and， or and non between triggering events are constructed to meet the requirements of intelligent monitoring. The alarm combination logical operation algorithm of monitoring system based on time series is constructed by introducing event triggering time， sequence， priority and other factors， All triggering events could trigger the alarm of video monitoring system according to the regulations of time series combined logic operation. The experimental results show that the proposed algorithm can synthetically apply multi?video signal source to realize the mixed use and alarm of multi triggering signals with multi video signal source synthetically， and realize the safe， controllable， accurate and convenient intelligent monitoring.

随着信息技术的发展与社会的进步，人性化管理和现代信息通信技术（ICT）有机融合，通过“技术+社区+服务平台”组合的方式，构建了完善的智慧城市、智慧小区的服务体系;同时，也促进了智能视频监控技术的广泛应用，使得视频监控系统可以根据监控场景中相关规则要求，完成相应规则下控制任务事件，呈现出一定智能化的视频监控系统[1]。传统的监控系统中，触发报警信号集中于单一数据源和单一事件的分析、判断上[1?5]，监控任务相对单一[2?3]，可操作性不强[4?7];对于多任务的监控则需要多个监控系统来完成，结构相对复杂，浪费大量的人力物力而未取得理想的整体监控效果，无法满足更高层次系统全监控需求[1，8?12]。……
