摘要
该文首先分析研究了CBTC系统生成移动授权（MA）的流程,剖析了该流程存在的问题。然后对基于车-车通信的下一代列车控制系统的移动授权生成流程进行分析,说明了其相对于传统CBTC系统的优点。同时,该文还对适用于基于车-车通信的列车控制系统的基于相对速度的移动授权计算方法进行了数学建模和软件仿真,确认了相对于基于相对位置的移动授权计算方法,该方法可以缩小行车间隔,提高行车效率,降低车与车之间发生通信延时的影响。
In this paper, the generation of Movement Authority（MA） for a CBTC system is introduced and the problem in this generation is analyzed. Compared with CBTC system, the generation of MA for the next generation of train operation control system Based on vehicle to vehicle communication and its advantage is introduced. Meanwhile, the mathematical model for the method of MA calculation Based on relative velocity for the train operation control system Based on vehicle to vehicle communication is established and a software is written to test and verify the performance of this method compared with the method if MA calculation Based on relative position for a CBTC system. It turns out that this method can optimize tracking interval, improve the transportation efficiency and eliminate the effect of communication delay between vehicles.
