摘要
智能化乘客信息系统,综合利用多媒体网络技术为乘客提供信息服务。以802.11n和3G技术进行混合组网可在列车运行中提供较高带宽,实现信息的全区域覆盖。采用多速率接口协议栈,可与地铁多个专业系统互联互通,并方便地获取运营信息;然后通过LCD、查询终端、移动互联网等多种媒介,实时交互式呈现时间、列车到发站、客流等运营信息,可使乘客便捷舒适地乘坐地铁,提高了地铁运营水平。
The Intelligent Passenger Information System makes use of intelligent multimedia network technologies to provide information services for passengers and adopts the technologies of 802.11n and 3G to construct hybrid network with higher bandwidth for subway operations,realizing full region coverage of data.Multi-rate interface protocol stack were used to provide connection and interoperation with several specialty systems for the purpose of operation data collection.Through LCDs,inquiry terminals,mobile Internet,and other interactive medias,real-time operational information,including time,departure and destination station of trains,passenger flow and so on,could be displayed interactively,facilitating passengers riding subway conveniently and comfortably and enhancing the level of subway operation.
