轨道交通乘客信息系统的设计

Design of Passenger Information System for Rail Transit

基于综合计算机网络技术和数字多媒体技术,提出了轨道交通乘客信息系统的一种设计方案,详细阐述了系统总体结构、主要功能和运行模式。该系统采用模块化设计,由控制中心子系统、车站子系统、网络子系统、车载子系统组成,具有正常、准实时、录播等多种运行模式,可实现运行信息播报和显示、视频资讯、告警、自诊断、图像监控等功能,并可与其他系统进行数据交换,不仅支持多任务管理,而且支持多用户管理。该系统的设计与实现可以为乘客提供直观、高效和人性化的服务,提高地铁运营管理水平,扩大地铁对乘客服务范围。

Based on computer network technology and digital media technology,this paper discusses an optimization scheme of rail transit passenger information system,including overall structure,basic function and operation mode.This system was modular in design,composed of control center subsystem,station subsystem,networking subsystem and automotive subsystem,possesses normal,quasi real-time,recording and other operating modes,was able to broadcast and display vehicle operation information,publish video information,implement self-diagnosis and image monitoring,and can exchange data with other systems.It is not only supports multi-task management,and supports multi-user management.Design and implementation of the system will provide direct,efficient and humanized service for passengers,improve the management of subway operation,and expand the service scope.
