摘要
根据上海轨道交通网络化发展需求,将模拟架构的PA(广播)系统和PIS(乘客信息系统)更新为数字构架的音视频统一信息服务系统。介绍了融合后的音视频系统的结构、技术特点和应用情况。该系统实现了语音播报及图文信息发布的深度融合,方便运营管控的同时提升了运营服务质量,降低系统维护难度的同时提升了维护效率。目前的上海轨道交通既有线路中,1号线是唯一完成音视频融合改造的线路,将传统意义上完全独立的PA和PIS进行融合,在实现并优化系统固有功能的前提下,实现了信息播报内容统一、信息播报操作统一和联动功能统一。
According to the development needs of Shanghai rail transit networking,the analog architecture of PA(public address)system and PIS(passenger information system)is upgraded to a digital architecture audio-video unified information service system.The structure,technical features,and application of the integrated audio-video system are introduced.The system achieves deep integration of voice broadcasting and graphic-text information dissemination,enhancing management-control and improving service quality for operation,while reducing complexity and increasing efficiency for system maintenance.Currently,among the existing Shanghai rail transit lines,Line 1 is the only line that has completed audio-video integration and modification.By merging the conventionally separate PA and PIS systems,under the premises of realizing and optimizing system inherent functionalities,the system achieves unified information broadcasting content,unified information broadcasting operation,and unified linkage function.
