云物大智、区块链、CPS间的关系及在铁路领域研究综述

云计算、物联网、大数据、人工智能(AI)、区块链、信息物理系统(CPS)为前沿新兴技术领域,它们并非彼此孤立,而是相互关联、相辅相成、相互促进的。介绍它们的内涵、关系及在铁路领域的应用探索。物联网是数据源,大数据是基础资源,云计算是基础设施,人工智能是核心算法,区块链为铁路领域业务基础架构和运行机制的变革创造条件,信息物理系统是贯穿信息空间与物理空间之间基于数据自动流动的状态感知、实时分析、科学决策、精准执行的一套综合技术体系。这些新技术的综合应用、交叉支撑、循环进化的良性迭代,将积极促进铁路智能化的发展。

Summary of relations among cloud computing,internet of things,big data,artificial intelligence,block chain,cyber-physical system and their application in railway field

Cloud computing, internet of things, big data, artificial intelligence, block chain and cyber-physics system (CPS) are the frontier emerging technologies. Connotation of these technologies and their relationship are introduced in this paper. These technologies are not isolated from each other, but interrelated, complementary and mutually reinforcing. Internet of things is the data source, big data is the basic resource, cloud computing is the infrastructure, artificial intelligence is the core algorithm. Block chain can create conditions for the transformation of business infrastructure and operation mechanism in railway field. CPS is a set of integrated technology system that runs through the information space and physical space based on automatic data flow, including state perception, real-time analysis, scientific decision-making and precise execution. The comprehensive application of these new technologies, crosssupport and virtuous iteration of cyclic evolution will actively promote the development of railway intellectualization.
