摘要
对列车旅客信息系统全数字化信息传输中的系统结构、总线时分复用控制及总线式电话交换控制等关键技术进行研究，并给出用３台Ｒｅｎｔｉｕｍ１６６微机通过３Ｃ５０９网卡连网，构成一个包含３个节点的旅客信息系统实验模型。在该模型上，已实现了同时进行一路ＶＣＤ电视节目和一路ＣＤ立体声音响播放以及公务电话的交换控制和通话。
The key techniques of data transmission of full digital passenger information systems of high speed trains is investigated, which involves system architecture, time division multiplexing control and telephone swap control on bus. Three Pentium 166 computers are connected through 3C509 network cards to build a model system, on which broadcasting of VCD programs and CD stereo music and the telephone swap control or communication of public affairs are realized.
