摘要
CTCS-3型列控系统中,RBC切换是车—地之间大规模数据连续、可靠双向传输的瓶颈,对列车安全、高效运行影响至巨.本文提出并研究了一种新的基于高速列车主体性的越区RBC切换模型,由RBC向列车发送隐性移动授权的基础数据,列车作为主体对基础数据进行融合计算生成移动授权,即通过隐性移动授权的显化过程来实现列车运行控制;同时,对预告应答器的设置作了适应性的调整.性能分析与仿真实验表明,新模型可以显著提高行车组织效率和增强列车运行的安全性.
In the CTCS-3-based train control system, the radio block center （RBC） handover becomes the bottleneck of the continuous and reliable hi-directional transmission of massive data between train and groumt, which exerts a giant impact on the safety and efficiency of train operation. The paper puts forward a RBC handover model based on train subjectivity. The movement authority is hidden in the basic data, which is send by one or two neighboring RBCs to trains. The Train acts as the main body to generate the movement authority with the basic data, namely, the clarity of the hidden movement authority is used to realize the automatic train control. Moreover, the position of the notice balise is adapted for the new model. Performance analysis and simulation experiments show that the proposed model significantly improves traffic organization efficiency and further enhance the safety of train operation.
