Abstract

The invention provides an information system used for the carriages with broadcast and an information system applied to the carriages without broadcast in a passenger train in which coaxial cables are arranged. The information system used for the carriages with broadcast comprises a server which is used for receiving and storing Ethernet data and sending the Ethernet data to an Ethernet switch; the Ethernet switch which is used for receiving the Ethernet data from the server and sending the Ethernet data to equipment in the coaxial cable for transmitting the Ethernet signals and to an audio-video device; the equipment in the coaxial cable for transmitting the Ethernet signals which is used for receiving the Ethernet data from the Ethernet switch and converting the data into unipolar signals and then sending the unipolar signals through the coaxial cable to the carriages without broadcast; the audio-video device which is used for receiving the Ethernet data from the Ethernet switch, broadcasting video and audio corresponding to the Ethernet data and sending the audio signals to the carriages without broadcast.

Description

technical field [0001] The invention relates to a railway passenger information service system, in particular to an information system for broadcasting carriages of passenger trains and an information system for non-broadcasting carriages of passenger trains. Background technique [0002] figure 1 It is a block diagram of a passenger train video playback system according to the prior art. like figure 1 As shown, most of the existing video playback systems for passenger trains use video servers as signal program sources, which are mixed into one radio frequency signal by modulators and mixers, and transmitted to each compartment by coaxial cables. Each car utilizes the main line amplifier to compensate the level loss caused by car connection and cable transmission. The radio frequency signal is transmitted to each LCD TV by splitters and distributors. [0003] The existing video playback system for passenger trains is similar to Cable Television (CATV for short), which is...
