CBTC系统中现地工作站合设方案研究

Research on the Design of Local Workstation Integration for CBTC System

在CBTC系统架构中,联锁上位机和列车自动监控(ATS)值班工作站作为两个独立的操作终端,承担着不同的功能和角色。随着CBTC系统产品在国内的广泛应用以及地铁精细化管理和减少维护设备要求的提出,运营方对联锁上位机和ATS车站值班工作站提出了合设的招标要求。为了实现此目标,文章通过对比分析CBTC系统架构中两个操作终端的特点,提出了3种不同的现地工作站合设方案。其通过变更接口架构和部署位置,在满足功能需求的基础上,均实现了统一终端界面风格和操作方式的目标,提高了用户的体验和便利,减少了车站设备数量。其中方案一已在长沙市轨道交通3号和4号线上实现工程应用,目前线路已安全运营合计27个月;方案二和方案三为后续合设方案提供了思路,但需要进一步的工程化应用。

In the communication based train control system(CBTC)signaling system architecture,CI operation control and automatic train supervision(ATS)local workstation are two independent operating terminals playing different roles.However,with the wide application of CBTC system in China and the refined management and operation requirements of the metro system,many customers have asked for local workstation integration.This paper proposes three types of local workstation architecture scheme by comparing the functional differences between the two terminals in the CBTC system architecture.By changing the interface architecture and deployment location,the three schemes have achieved the goal of unifying terminal interface style and unifying operation mode on the basis of meeting the functional requirements,improving the user experience and convenience,and reducing the number of station equipment.Scheme 1 has been safely operating on Changsha Urban Mass Transit Lines 3 and 4 for a total of 27 months.Scheme 2 and 3 provide ideas for the subsequent joint design plan,but further engineering applications are required.
