地铁乘客信息显示系统(PIDS),依托地面有线网络及车-地无线传输网络,将运营信息、娱乐等其他视频信息传递到车载流媒体计算机,再通过车载显示终端将信息提供给乘客,为乘客提供信息服务。由于PIDS的服务性、稳定性及实时性要求,需要开发更加稳定的传输方式,为此介绍以数据传输为
Subway Passenger Information Display System (PIDS) relies on terrestrial wired networks and car-to-ground wireless transmission networks to deliver operational information, entertainment, and other video information to on-board streaming media computers and to provide information to passengers through on-board display terminals for passengers Provide information services. Due to the service, stability and real-time requirements of PIDS, more stable transmission modes need to be developed. To this end, data transmission is described as
