介绍北京地铁5号线自动售检票(AFC)系统的构成,以及系统主干网数据流量的传输内容,以全线23座车站中终端设备数量最多的北土城东路站作为分析的参考基点,来验证主干网实时传输需要的数据带宽和主干网集中传输数据所需的时间是否满足运营需要。
This paper introduces the composition of AFC system of Beijing Metro Line 5 and the transmission of data flow in the system backbone network. Taking Beitucheng East Road Station with the largest number of terminals in the 23 stations as the reference point for analysis, Verify that the data bandwidth required for real-time transmission on the backbone network and the time required for the backbone network to centrally transmit data meet the operational requirements.
