面向CPS系统的通信数据价值评估建模研究

Research of Communication Data Value Assessment Model Based on Cognitive Self-adapting for CPS

信息物理系统(Cyber Physical System,CPS)集计算、通信、控制为一体,通信在其中发挥着不可替代的作用。CPS系统的复杂集成特性,决定了其存在海量异质的数据,如果采用传统的透明通信方式,不考虑数据的价值,势必造成系统资源的极大浪费,降低网络系统的传输效率。因此,提出了基于数据价值进行选择性传输的理念,结合认知自适应方法构建了通信数据价值的评价模型。通过研究综合多指标的信息价值熵理论的CPS信息综合评价模型,解决CPS系统中业务信息的选择性传输问题。提高CPS系统中数据的高效传输,有望解决CPS系统中数据传输的海量性和实时性难题。

Cyber Physical System（ CPS） integrates the functions of computation,control and communication together. The complex integration of CPSs has huge device groups to constitute a large heterogeneous network by interconnection,and both devices and businesses are miscellaneous and various. The key point is the research on how to transfer the valuable information in different businesses effectually and reliably in limited transfer resources. In this paper,we propose a concept of selective transmission scheme based on data value,and construct an evaluation model for the value of communication data by combining the cognitive adaptive method. CPS information comprehensive evaluation model,based on the comprehensive evaluation of information value entropy,is studied to solve the problem of selective transmission of business information in CPS system. Improvement of data transmission efficiency in CPS system is expected to facilitate mass and real- time data transmission in CPS system.
