城市轨道交通CBTC系统升级为TACS系统的方案探讨

Study on CBTC system upgrading to TACS system plan for urban rail transit

分析比较城轨CBTC系统和TACS系统的架构,结合改造项目特点,为确保系统平稳升级,提出车载安全平台、轨旁安全平台和控制中心ATS的不同改造策略。采用成熟的通用硬件安全平台,通过更新软件和数据升级至TACS系统。对于信号系统大修改造项目,可根据各系统设备的不同使用年限,采用新增和利旧相结合的系统设备配置原则。TACS系统作为CBTC系统的升级版既可节约机房安装空间,还可最大限度利旧既有CBTC系统设备,满足信号系统改造需求。

By analyzing and comparing the architecture of the CBTC system and the TACS system,while combining the characteristics of the revamping project,and in order to ensure the smooth upgrade of the signal system,different renovation strategies for the onboard safety platform,wayside safety platform and OCC ATS are proposed.The software and data for the new TACS system will be configured on a mature hardware safety platform.For the signaling revamping project,based on the different life cycles of the equipment,part of the system equipment will be reused,while other parts will be newly added.As an upgrade of the CBTC system,the TACS system can save installation space in equipment room,reuse part of existing CBTC system equipment,and meet the requirements of the signal system upgrade.
