摘要:
［目的］与现有CBTC(基于通信的列车自动控制)系统控制机理不同，列车自主控制系统通过直接控制轨旁资源实现列车自主运行。为了提高道岔区段的运行效率，需研究列车自主控制系统在道岔区段的控制算法，采用颗粒度更小的道岔安全区域作为列车自主控制系统的控制资源。［方法］列车自主控制系统的控制算法将轨道区段视为共享资源，道岔安全区域单独分配给列车使用。对单开道岔区段和交叉道岔区段场景下的列车自主控制系统和CBTC系统进行了对比分析，并采用真实列车控制系统和道岔的参数进行仿真计算运行提升效率。［结果及结论］与CBTC系统的传统联锁算法相比，列车自主控制系统的道岔安全区域控制算法性能更好。在单开道岔区段场景中，列车运行安全间隔提升率最大达到74.5%；在交叉道岔区域场景中，列车道岔通过时间提升率最大达到33.8%。通过在系统架构和控制算法上的优化，列车自主控制系统增加系统灵活性和效率，为下一代列车控制系统重要发展方向。
Abstracts:
［Objective］ Unlike the existing CBTC (communication-based train control) system control mechanism, the ATC (autonomous train control) system achieves autonomous train operation by directly controlling wayside resources. To improve the operational efficiency of turnout segments, it is necessary to study the control algorithm of ATC system in turnout segments, using smaller granularity turnout safety zones as control resources for ATC system. ［Method］ The control algorithm of ATC system considers the track section as a shared resource, with turnout safety zones allocated separately for train use. A comparative analysis is conducted between ATC system and CBTC system in scenarios with single-slip turnouts and crossover turnouts, and simulation calculations are performed using real train control system and turnout parameters to improve the operational efficiency. ［Result & Conclusion］ Compared to the conventional interlocking algorithm of CBTC system, the control algorithm of ATC system for turnout safety zones performs better. In single-slip turnout scenarios, the maximum increase in the safety interval for train operation reaches 74.5%. In crossover turnout zone scenarios, the maximum increase in train turnout-passing time reaches 33.8%. By optimizing the system architecture and control algorithm, ATC system increases flexibility and efficiency, serving as an important direction for the development of the next generation train control system.
