摘要/Abstract

摘要：

基于通信的列车自动控制(communication based train control,CBTC)系统采用地铁长期演进系统(long term evolution-metro,LTE-M)完成车地之间的数据通信, 并限定数据在较低的时延内完成传输.将CBTC系统中列车终端接入基站的通信模型化为排队论体系中的M/M/1/m/m模型,推导LTE-M应用于CBTC时数据传输时延的概率预测方法,并给出满足CBTC需求的相关条件,为LTE-M系统的可靠性设计提供参考.

Abstract:

LTE-M system is proposed to be used in the next generation of rail transit communication based train control (CBTC) system to achieved at a communication between the way side and vehicles. Such communications require low delay of data transit. Communication of vehicle terminal accessing the base station is modeled as M/M/1/m/m in the queuing theory. A method is developed to predict probability of data transit delay when LTE-M is used in CBTC. Related conditions are presented to meet the CBTC requirements. This study provides a reference for reliability design of the LTE-M system in the future.

Key words: rail transit, communication based train control (CBTC), long term evolution-metro (LTE-M), queuing theory, communication delay
