摘　　要：对监控视频数据进行基于深度学习模型的智能分析可提升文物博物馆单位的文物安全风险防范能力。针对文物博物馆单位希望充分利用现有空闲可用计算资源完成更多视频数据智能分析的需求,该文提出一种视频智能分析任务动态调度方法,将边缘侧文物博物馆单位内拥有空闲可用计算资源的设备作为计算节点组建边缘算力协同系统进行视频智能分析任务的处理。该文把要解决的问题建模为2维多重背包问题,并采用动态规划的方法,求解如何在边缘算力协同系统上动态分配视频分析任务使得每一个时间周期内系统执行任务获得的安全价值效益最大化的问题。仿真实验结果表明,所提方法能在不干扰文物博物馆单位正常业务应用服务的情况下,根据对系统当前资源使用状态监控与分析,动态分配视频智能分析任务,达到了最大化安全价值效益的目的。Intelligent analysis of surveillance video data based on deep learning models can improve the cultural relics security risk prevention capabilities of cultural relics museum units.In view of the needs of cultural relics museum units to make full use of existing free and available computing resources to complete more intelligent analysis of video data,a dynamic scheduling method for video intelligent analysis tasks is proposed.The device serves as a computing node to form an edge computing power collaborative system to process intelligent video analysis tasks.In this paper,the problem to be solved is modeled as a two-dimensional multiple knapsack problem,and the method of dynamic programming is used to solve how to allocate dynamically video analysis tasks on the edge computing power collaborative system so that the security value and benefits obtained by the system execution tasks in each time period problem of maximization.The simulation results show that the proposed method can dynamically allocate video intelligent analysis tasks based on the monitoring and analysis of the current resource usage status of the system without interfering with the normal business application services of cultural relics museum units,achieving the goal of maximizing security value and benefits purpose.
