列车自主运行系统下自动化场段的关键功能

Key Functions of Automated Depot under TACS System

[目的]TACS(列车自主运行系统)下,自动化场段的关键功能对列车运行效率的影响较大。有必要围绕场段内主要作业,根据TACS的特性,对TACS下自动化场段关键功能进行研究。[方法]分析了TACS的特性,并从场段内调车功能、列车唤醒与休眠功能、列车出库功能及列车回库功能等方面,结合既有CBTC(基于通信的列车控制)系统自动化场段存在的问题,详细阐述了TACS下自动化场段的关键功能。[结果及结论]TACS不需要配置联锁子系统与轨旁次级检测设备。在TACS自动化场段,列车收到调车任务后,主动申请线路资源,自主完成作业任务;取消了休眠区的设置,唤醒时无需读取信标校验位置。TACS自动化场段具备稳定的唤醒功能、灵活的休眠点,能实现高效的出库作业,对库线要求较低,且调车流程简便。

[Objective]Under TACS(train autonomous control system),the key functions of automated depot significantly impact train operational efficiency.It is essential to study these critical functions in automated depot by focusing on the main depot operations in the context of TACS characteristics.[Method]The characteristics of TACS are analyzed,in light of existing issues in current automated depot with CBTC(communication-based train control)system,the key functions of TACS automated depot are expounded from depot shunting,train wake-up and sleep,train departure,and train storage perspectives.[Result&Conclusion]TACS eliminates the need for setting up interlocking subsystems and trackside secondary detection equipment.In TACS automated depot,once a train receives a shunting task,it proactively requests line resources and independently completes the operation.The sleep zone is no longer required,and the train does not need to read beacons to verify its position upon wake-up.TACS automated depot features stable wake-up functions,flexible sleep spots,efficient train departure operation,reduced depot track requirements,and simplified shunting process.
