摘要
针对物联网视频感知的动态同步问题,本文用π网理论建立了物联网视频感知的抽象模型DSAM,以描述其动态同步问题。首先建立基于π网的物联网视频感知抽象模型DSAM,然后对模型进行了状态演变、模型变迁和动态交互等分析,最后利用模型DSAM对实例进行分析和仿真。通过对模型DSAM的仿真和分析可知,该模型能够正确处理物联网视频感知的动态同步并发性,具有一定的实用价值。
Aiming to solve the dynamic synchronous problems in the video sensing of Internet of Things,the paper establishes a Dynamic Synchronization Abstract Model (DSAM) based on the π-nets theory to describe the dynamic synchronous problems.At first,the DSAM of the video sensing of Internet of Things is established based on π nets.And then this paper analyzes state evolution,model transition and dynamic interaction.At last,The DSAM is used to analyze and simulate examples.Through the analysis and simulation of the DSAM,it is known that the model can be used to correctly deal with the dynamic synchronous concurrency of the video sensing of Internet of Things,and it has certain practical value.
