摘要: 为推进智慧城市轨道交通的发展,车载乘客信息系统(PIS,Passenger Information System)亟需提供更贴合乘客出行需求、能够与运营动态自适应的信息服务。文章在分析车载PIS发展趋势、城市轨道交通乘客服务情景感知信息源的基础上,提出PIS情景感知服务技术方案,采用基于云边端融合的开放架构搭建系统,利用边缘端设备完成乘客服务情景感知信息的采集、传输、分析、调度处理能力,形成伸缩性强、性能更佳的弹性云平台,有助于提升车载PIS的自适应性,为乘客提供更人性化的服务体验。

Abstract: To push forward the development of smart urban rail transit, the on-board PIS is required to offer more suitable information services to meet passengers's ride demand in a way adaptive to the operating status of the urban rail transit. Through analyzing the development tendency of on-board PIS as well as context aware data sources for passenger information services, a technical solution to context aware services of on-board PIS is proposed, in which a open cloud edge fusion architecture is adopted to make use of the processing capability of the edge-side equipment in data collection and analysis as well as scheluding of passenger information services, thus forming a more scalable and flexible cloud with improved performance. This solution can help enhence the adapability of on-board PIS and improve passenger-oriented formation services. -
