| Abstract: | 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. |
