基于软件定义的移动信息物理融合系统

A Mobile Cyber-Physical System Based on Software Definition

在汽车和飞机等交通工具上安装传感器等设备,导致了新一代移动信息物理融合系统MCPS(Mobile CyberPhysical System)的出现.针对MCPS主要以硬件资源为核心,自动化水平不高的问题,本文提出了一种基于软件定义的MCPS建模方法.通过结构分析与设计语言AADL(Architectural Analysis and Design Language)对硬件资源虚拟化,然后使用软件定义的方法对硬件资源进行分析和处理,可以有效提高MCPS系统的自动化水平.以移动车辆自主处理分析传感器数据并控制车辆的驾驶为案例,详细介绍系统的组成和建模过程.并通过添加安全附件对该模型的安全性进行分析验证,证实了基于软件定义建模的可行性与有效性.

Installing sensors and other devices in vehicles such as cars and aircraft have led to the emergence of a new generation of mobile cyber-physical system(MCPS). However, MCPS is mainly based on hardware resources and has low automation level. A MCPS modeling method is proposed based on software defined approach.Virtualizing the hardware resources by AADL(Architectural Analysis and Design Language), and then analyzing and processing the hardware resources through the software-defined method, the automation level of the MCPS system can be effectively improved. The mobile vehicle which autonomously processes and analyzes sensor data for controlling vehicle driving is taken as an instance and the system composition and model is described. Finally,the security of the system is analyzed by adding a secure annex. This instance demonstrates the feasibility and effectiveness of software-defined modeling method.
