摘　　要：可视铁路调度通信系统以软交换技术为核心,应用于铁路调度通信领域,实现调度中心和各车站、工区之间的语音、视频、数据等多媒体通信业务,而且可以实现主系统的双份或多份互备冗余,两台或多台主系统核心服务器可以异地放置,以IP数据网互联,起到异地容灾和异地备调作用。Soft switching technology is the core of visual railway scheduling communication system. It has been applied in railway scheduling communication, providing multimedia communication services be- tween the traffic control center and stations and work areas . The system is enabling double or more cop- ies backup for the main system with dual or more core servers of the main system being placed at different location using IP data network for interconnection to offer remote disaster recovery as well as to serve as remote adjustment.
