旅客列车旅客信息系统数字信息子系统的研究

Study of Digital Information Subsystem for Passenger Information System in Passenger Trains

探讨了旅客列车旅客信息系统中数字信息子系统基本构成、系统配置、主要功能和系统数据库的构造等研究内容。同时，还讨论了本数字信息子系统局域网与ＩＮＴＥＲ－ＮＥＴ互连的必要性及方法。其研究工作为我国旅客列车旅客信息系统的进一步研究打下了良好的基础。

This paper deals with the basic structure, system configuration,main function, and system database in the construction of the digital information subsystem for Passenger Information System (PIS) in passenger trains. Furthermore, the necessity and method of networking between the subsystem LAN and the INTERNET are briefly introduced. The research results make a good foundation for further study of the PIS of railway passenger trains.
