摘要:
［目的］基于车车通信的TACS(列车自主运行系统)作为新一代列车控制系统，与CBTC(基于通信的列车控制)在系统架构上存在显著差异。需对TACS在设备故障情况下的降级运行方案进行研究，以保证列车安全、可靠运行。［方法］阐述了基于车车通信TACS的特点，介绍了TACS的架构，并分析了TACS的特征。分析了TACS的降级运行需求，提出了基于“雷达+视觉方式”多传感器融合技术的TACS降级运行方案。［结果及结论］该降级运行方案能有效解决列车的测速、定位、间隔防护问题，并能有效检测轨道区域异物入侵。
Abstracts:
［Objective］ As a new generation of train control system, the TACS （train autonomous control system）based on vehicle-to-vehicle communication is significantly different from CBTC (communication-based train control) in system architecture. It is necessary to conduct a research on the degraded operation scheme of TACS in the event of equipment failure to ensure safe and reliable train operation. ［Method］ The characteristics of TACS based on vehicle-to-vehicle communication is elaborated and analyzed, and its architecture is introduced. The degraded operation requirements of TACS are analyzed, and a degraded operation scheme of TACS based on multi-sensor fusion technology of 'radar plus visual method' is proposed. ［Result & Conclusion］ The above degraded operation scheme can effectively solve problems such as train speed measuring, positioning, and interval protection, and effectively detect foreign object intrusion in the track area.
