CBTC系统数据管理过程分析和设计

摘要

CBTC system is a typical and critical safety system.The use of standardized components and subsystems has led to reliance on configuration data to define the functionality of the system.In this paper,considering the space,consistency and correlation characteristics of CBTC system data,a method of data management process analysis and design based on data supply chain (DSC) is put forward,seven steps of a specific design process are given and the availability and feasibility of this method are discussed.%阐述基于通信的列车自动控制(CBTC)系统的功能,讨论其系统数据所具有的空间性、一致性和关联性等特点.针对CBTC系统数据的特点,提出一种基于数据供应链(data supply chain,DSC)对数据管理过程进行分析和设计的方法,给出具体设计过程的7个步骤,并讨论该方法的可用性和可行性.
