摘要

现行基于通信的列车自动控制系统（CBTC）部署于2.4 GHz免执照频段，易受手持Wi-Fi热点干扰，已造成深圳和北京多起地铁紧急制动事故。在1 785～1 805 MHz 频段同频邻频先用通信系统的干扰下，为CBTC 系统选择合适的部署频段、工作带宽和布站间隔，提高其系统吞吐量并降低紧急制动概率十分必要。针对该问题，首先通过分析确定干扰研究场景，并基于确定性计算的方法得到干扰方和CBTC列车端之间的安全隔离，随后通过系统级仿真比较不同条件下CBTC系统下行链路的吞吐量和CBTC系统紧急制动概率，得到适合CBTC部署的工作频段、带宽和布站间隔。

Abstract

Communication based train control system (CBTC) is assigned in 2.4 GHz unlicensed band

and is easily interfered by Wi-Fi

which caused several emergency brake accidents in Shenzhen and Beijing.Under identical and adjacent interferences from existing systems

choose appropriate frequency band

working bandwidth and station spacing to improve throughput and emergency brake probability for CBTC system is necessary.Firstly

interference research scenarios were analyzed.Then

safety isolation between CBTC train and interferes through deterministic calculation was calculated.Afterwards

appropriate working bandwidth

frequency band and BS spacing was obtained by comparing system level simulation results

including throughput and emergency brake probability

in different conditions.
