摘要
结合南京地铁1号线建设,介绍地铁车站乘客信息系统的一种设计方案。该方案采用基于IP的数字电视广播(DVB)技术,有效地实现系统的既定功能,在已有的旅客向导牌系统设计中,充分挖掘系统潜力,在原LED显示系统上,适度增加全线千兆骨干以太网络和PDP显示播控设备,并对信号系统接口进行自主二次开发,通过PDP显示屏资源置换等融资方式,使得在全系统总造价提高不多的基础上,建成全国首个基于星型千兆以太网的地铁全数字实时乘客信息系统。
With the construction of Nanjing metro Line 1 as the background, this paper introduces a design option for the Passenger Information System （PIS） in metro stations. The design is based on Digital Video Broadcast over IP and realizes the established function of PIS. Considering the old design of Passenger Information and Indication System, the new design makes full use of system potential, adds 1 000 MB star-topology Ethemet and PDP display control equipment, and conducts on its own research about the interface design of ATS. Thereupon, the first digital real time PIS has been installed in China, while the cost of the system is a little more than that of the old one.
