Definitions

  • the present invention relates to a communication system for delivery of information to subway trains, and more particularly to a communication system for delivery of information to subway trains, which is capable of providing moving picture information of a high picture quality to those subway trains in a real time fashion via terminals respectively installed in the subway trains .
  • subway trains are representative public transportation means used every day by ten million or more passengers.
  • the number of passengers using such subway trains has gradually increased due to severe traffic jam. For this reason, new subway lines are being additionally constructed.
  • improvements in services are being made for the convenience of passengers.
  • service improvements may include an improvement in the interior environment of station buildings and an addition of installations for physically handicapped persons.
  • an object of the invention is to provide a communication system for delivery of information to subway trains, which is capable of providing moving picture information of a high picture quality, such as important internal and external news, information about shares, life information, and advertisements, to those subway trains in a real time fashion via terminals respectively installed in the subway trains, thereby allowing passengers to learn and acquire various information during the riding.
  • moving picture information of a high picture quality such as important internal and external news, information about shares, life information, and advertisements
  • this object is accomplished by providing a communication system for delivery of information to a subway train, comprising: a relay unit installed in a subway station building and adapted to selectively output a moving picture information signal collected via Internet and edited or a broadcasting signal provided by an Internet broadcasting station; a plurality of first transmitters/receivers installed on the wall of a subway tunnel or a rail on the ground while being spaced apart from one another by a desired distance, the first transmitters/receivers serving to transmit the moving picture information signal outputted from the relay unit to train units of the subway train during the running of the subway train; a plurality of second transmitter/receivers each installed at a desired position on an associated one of the train units of the subway train, the second transmitter/receiver installed at a control one of the train units serving to receive the moving picture information signal outputted from each of the first transmitters/receivers, and the remaining second transmitters/receivers serving to deliver the moving picture information signal between adjacent ones of the train units;
  • the second transmitter/receiver installed at the control train unit comprises a transmitting module for outputting the train position signal under a control of the server associated therewith, and a receiving module for receiving the moving picture information signal outputted from one of the first transmitters/receivers, and transmitting the received moving picture information signal to the server of the control train unit.
  • a communication processor 34 serves to transmit, to the relay unit 10, data received via the receiving module 31 and information about the state of the associated first transmitter/receiver.
  • the communication processor 34 also controls the operation of the associated first transmitter/receiver in accordance with various control commands while relaying desired ones of the control commands to another first transmitter/receiver arranged downstream from the communication processor 34.
  • the present invention provide a communication system for delivery of information to subway trains, which is capable of providing moving picture information of a high picture quality, such as important internal and external news, information about shares, life information, and advertisements, to those subway trains in a real time fashion via terminals respectively installed in the subway trains, thereby allowing passengers to learn and acquire various information during the riding while laying out their times to most advantage.

Abstract

L'invention concerne un système de communication pour la transmission d'informations à des rames de métro, qui comprend un relais situé dans une station de métro fournissant sélectivement un signal d'information d'image en mouvement capté via Internet et édité ou bien un signal de diffusion issu d'une station de diffusion sur Internet. Le système comprend aussi plusieurs premiers émetteurs/récepteurs installé sur la paroi d'un tunnel de métro ou sur un rail au sol, espacés selon un intervalle souhaité, pour transmettre le signal d'information d'image en mouvement fourni par le relais aux rames de métro en cours d'exploitation. Le système comprend en outre plusieurs seconds émetteurs/récepteurs installés en des points déterminés sur l'une des unités de rame de métro associées, sachant que lesdits émetteurs/récepteurs installés sur une unité de rame de métro de contrôle permettent de recevoir le signal d'information d'image en mouvement issu de chacun des premiers émetteurs/récepteurs. Les seconds émetteurs/récepteurs restants distribuent le signal d'information d'image en mouvement entre rames de métro adjacentes. Enfin, plusieurs serveurs installés respectivement dans les unités de rame de métro transmettent le signal d'information d'image en mouvement issu des seconds émetteurs/récepteurs d'unités de rames de métro associées, vers des terminaux respectivement installés dans les rames de métro. Les serveurs sont reliés entre eux par le biais d'un réseau local avec ou sans fil.
