摘　　要：目前广泛应用的基于通信的列车控制系统(CBTC)主要由联锁和区域控制器协同配合为列车分配线路资源,基于“车-地-车”数据交互架构实现列车安全防护。这种系统结构复杂、延时较大,导致运营效率较低。通过分析轨旁控制系统一体化和车车通信的技术现状,提出新一代CBTC系统方案,从系统结构和列车运行控制流程2方面进行研究,设计实现在线列车运行计划调整、列车及线路资源管理、车载自主计算移动授权等关键功能。该方案系统结构精简、维护方便、响应及时、运营灵活,能够极大地缩短列车运行间隔,提高运营效率,符合未来信号系统的发展方向。The widely used Communication Based Train Control(CBTC)system allocates the line resources by the collaboration work of the Computer Based Interlocking and the Zone Controller subsystems,and achieves train safety protection based on“train-ground-train”data interaction architecture.However,this system has a complex structure and significant latency,resulting in low operational efficiency.By analyzing the current technological status of trackside control system integration and vehicle communication,a new generation CBTC system solution is proposed.The research is conducted from two aspects:system structure and train operation control process.Key functions such as online train operation plan adjustment,train and line resource management,and on-board autonomous mobile authorization calculation are designed and implemented.This scheme has a simplified system structure,convenient maintenance,timely system response,flexible operation,and can greatly shorten train operation intervals,improve operational efficiency,which is in line with the development direction of future signal systems.
