基于车辆深度融合的列车自动运行系统

Automatic Train Operation System Based on Vehicle Deep Integration

[目的]传统ATO(列车自动运行)系统与车辆牵引系统/制动系统之间并没有建立直接、实时、双向的数据交互,在控车过程中无法获取车辆的牵引/制动状态和能力信息,进而导致ATO系统发出的控制指令可能与车辆实际能力不匹配、控制周期长、停车精度低等问题,需要将ATO系统和车辆系统进行深度融合。[方法]阐述了传统ATO系统的工作原理及存在不足。提出了基于车辆深度融合的列车自动运行系统(以下简称“融合ATO系统”),论述了融合ATO系统在系统架构、信息传输、车辆接口及系统功能等方面的融合优化措施。将传统ATO系统和融合ATO系统进行对比,对融合ATO系统的优势进行了分析。[结果及结论]融合ATO系统取消了ATO系统与车辆牵引系统/制动系统之间的中转环节,减少了通信链路,使得二者之间的信息传输更加丰富和透明。融合ATO系统可充分发挥车辆系统和信号系统各自的特性和优势,增强ATO系统与牵引系统/制动系统间的配合度,提高整体控车效果。

[Objective]Conventional ATO(automatic train operation)systems lack a direct,real-time,and bidirectional data exchange with the vehicle traction/braking systems.In the vehicle control process,information on the vehicle traction/braking status and capabilities is not available,which can lead to issues such as control commands from the ATO system not aligning with actual vehicle capabilities,long control cycles,and low parking precision,calling for a need to achieve deep integration between ATO and vehicle systems.[Method]The working principle and limitations of conventional ATO systems are discussed.The ATO system based on deep vehicle integration(hereinafter referred to as Integrated ATO)is introduced.The integration optimization measures of the Integrated ATO system in terms of system architecture,information transfer,vehicle interfaces,and system functionality are elucidated.A comparative analysis is conducted between conventional and Integrated ATO systems to highlight the advantages of the latter.[Result&Conclusion]The Integrated ATO system cancels the interlink between ATO and vehicle traction/braking systems,reduces communication links to enhance richness and transparency of information transfer between them.The Integrated ATO system leverages the characteristics and advantages of both the vehicle and signaling systems,enhancing the coordination between ATO system and traction/braking systems,thereby improving overall control effectiveness.
