摘要:
［目的］传统信号系统采用进路的方式管理轨旁资源并基于进路计算移动授权；而TACS(列车自主运行系统)通过列车为主体进行资源管理，效率更高。为实现列车在不同制式的线路上互通运行，有必要基于TACS和CBTC(基于通信的列车控制)系统融合提出新的资源管理方案。［方法］轨旁资源管理主要包含轨旁资源申请、联锁条件检查及方向锁闭、信号逻辑开放等阶段。基于轨旁资源管理设备的功能，按资源竞争场景和资源死锁场景，从资源共享及资源独享特性出发，详细阐述了各阶段的资源管理条件及管理内容。［结果及结论］新的资源管理方案通过轨旁资源方向属性及相关联锁条件，可有效规避正面冲突、侧面冲突等风险，与传统列车运行控制系统相比，新资源管理方案的安全性显著提高。结合信号机控制，该方案可满足TACS和CBTC系统间的兼容，还可有效规避多列车在同一道岔处由于运行任务并发而造成的运行死锁，确保运行效率。
Abstracts:
［Objective］ Traditional signaling systems manage trackside resources using routing-based methods and calculate movement authority accordingly. In contrast, the TACS (train autonomous circumnavigation system) manages resources from the perspective of train itself, resulting in higher efficiency. To enable train interoperation across lines with different signaling systems, it is necessary to propose a new resource management scheme based on the integration of TACS and CBTC (communication-based train control) system. ［Method］ The trackside resource management primarily involves the stages of wayside resource request, interlocking condition checking and directional locking, and signal logic release. Based on the functions of trackside resource management equipment, resource competition and deadlock scenarios are examined. The management conditions and content for each stage are elaborated from the perspectives of shared and exclusive resource characteristics. ［Result & Conclusion］ The proposed resource management scheme utilizes the directional attribute of trackside resources and associated interlocking conditions to effectively prevent risks such as head-on and side collisions. Compared to traditional train operational control systems, the safety in new resource management scheme is significantly enhanced. In combination with signal control, the scheme ensures compatibility between TACS and CBTC systems. It also effectively avoids operational deadlocks caused by concurrent train tasks at the same turnout, thereby ensuring operational efficiency.
