CPS在轨道交通领域的应用分析

Analysis of the application of CPS in the rail transportation

全国铁道交通日益增大的环境下,铁道交通的信息系统与安全监测成为首要研究对象,而铁路轨道缺陷检测技术是安全监测中重要监测指标之一。针对现代的通信网络、物理信息、应用技术已经远远超出传统轨道交通系统的需求范围,考虑信息物理融合系统(CPS)是依靠物理环境感知的基础上,通过网络通信的实时传输,利用信息世界的信息处理能力和广度适应计算,提高对物理世界的控制能力。首次将CPS概念引入到铁路轨道交通中,基于信息物理系统概念和轨道检测技术的特点,提出了基于CPS环境下轨道检测系统架构模型,实现铁路轨道状态感知,可靠远程超声自动检测、实时通信传递以及有效无误的安全控制。

With the increasing environment of railway traffic, the information system and safety monitoring of railway traffic becomes the main research object, and the railway track detection technology is one of the important monitoring indicators in safety monitoring. In view of the traditional rail transport system has been unable to meet the new generation of physical equipment information and networking needs, consider the information of the physical system(CPS) based on the reliable physical environment perception, through the real-time transmission network, using the information of the world to adapt to the general computing and information processing capabilities, to achieve precise control of the physical world. CPS was first introduced to the railway rail transportation, physical characteristics of information system concept and track detection technology based on CPS is put forward under the environment of track detection model based on system architecture, implementation of railway track state perception, reliable remote automatic ultrasonic detection, real- time communication transmission and effectively correct safety control.
