Definitions

  • the invention relates to a method for demonstrating Information in a plurality of vehicles where Master information on arranged in the vehicles Computers are saved, which are then at least each a demonstration device demonstrated in the vehicles with additional information with the help of at least a stationary transmitter and with the Computers connected receiving devices to the computers are transmitted in which the additional information be evaluated by the computers and depending on the from the additional information on the demonstrators presented information changed become.
  • the demonstration devices are designed as computer screens which the master information is presented to a user become.
  • the master information is given on Locations such as in a depot on the computer transferred and remain until a next stay in such a location unchanged because during no further data exchange when traveling between two depots takes place. Therefore, with the from the Methods known in the prior art merely provide information be presented with a topicality to the Linked date of transfer of master information is.
  • the present Invention based on the technical problem that Method for presenting information in a moving Vehicle to improve that information in high quality with simultaneous updateability and low implementation costs can be demonstrated.
  • the technical problem outlined above is according to the invention solved in that in at least part of the Vehicles the mobile receiving devices in addition as transmitters for the establishment of a mobile transmitter network are used and that the additional information also transmitted via the mobile transmitters become.
  • the knowledge of the method according to the invention lies first underlying that is only a part of the demonstrated Information needs to be updated regularly while the vast majority of information is one has sufficient timeliness to be used as master information to be stored on the computer. Therefore can the master information is stored in larger amounts of data be, so that at least the largest part of the presented information has a high demonstration quality. Only the information to be updated need additional information with the help of the transmitter and the receiving device on the computer be transmitted. This additional information is then used to change the information presented, in particular to update.
  • the mobile reception devices in addition as transmitters for building a mobile Network used and the additional information in addition to the at least one stationary transmission device also transmitted via the mobile transmitters. It is preferred that in all vehicles mobile transmission device is used. Furthermore can the additional information with the help of along the Routes of the vehicles of stationary transmission devices be transmitted.
  • the mobile Receiving devices simultaneously transmitting devices are base stations. This creates a self-organizing Network as any stationary and mobile Transmitters their position at irregular intervals, generated from a GPS signal, for example will send.
  • Each transmission device switches itself automatically similar transmission facilities located in the neighborhood into a network.
  • the network is based on this preferably on a bit transport technique, the so-called S3 technology (symbol stream switching) that the advantages of different switching technologies with each other combines. This will be done simultaneously and without delay a data transfer from each transmitter any other possible. So the network consists of the system approach from a large number of similar intelligent Radio end devices, which in turn have a limited Number of, for example, 3 to 8 neighboring stations each are constantly connected, with a maximum Distance of approx. 5 km is specified.
  • the transmitters exchange simultaneously and permanently with their neighboring stations via all connection-relevant Parameters such as free channels, quality of transmission, geographical position (via GPS or runtime calculation), public key for RSA encryption, ID-der Station etc.
  • connection-relevant Parameters such as free channels, quality of transmission, geographical position (via GPS or runtime calculation), public key for RSA encryption, ID-der Station etc.
  • an initialization computer with the database for information on the transmitters used.
  • the initialization calculator are also information computers with their database for all other transmitters of the mobile network.
  • Digital data packets can be sent from the sending device Transmitting device are transmitted and their addressees Find.
  • An application of an encryption technique can to protect against eavesdropping in the transmission chain.
  • Master information which is arranged on the vehicles Computers are stored, for example Short films, video art, computer animation, Cartoons and all forms of advertising information.
  • additional information for example, stop information, Transfer and connection information, especially for networking with other public or private transportation, weather news, News headlines, stock exchange information, event announcements, Citizen information or tourist information be transmitted.
  • the additional information will be then linked to the master information in such a way that in Dependence on the additional information on demonstration devices presented information changed, in particular be updated.
  • the master information is preferably created using a Data line over telephone, a local network or transferred to the computer by means of data medium exchange. For use in vehicles, this means that the master data during the stay on predetermined Locations, such as depots, on the computer be transmitted in the vehicle. For stationary applications the master data is, for example, by means of a telephone connection stored on the computer while the additional information - For example, while driving - via the send and Receiving devices are transmitted.
  • the help of the additional information changed the content of the information presented, so for example the data of a weather report updated with the help of the additional information, the during a predetermined time of the demonstrated Information presented periodically becomes.
  • the additional information points in a particularly preferred manner at least partially executable instructions, that can be interpreted using the computer.
  • Control commands are thus transferred to the computer to not only the content, but also the chronological order change the information presented. Thereby the timing of the information presented, So the program itself, influenced, for example insert a current headline. A great topicality of the presented information is thus achieved without the information of the whole Programs must be transferred.
  • a broadcasting studio 2 there is a production of the ones to be shown Master and additional information instead. It will So all the basics for a given program Unit of time, for example a daily program in Form of individual program sequences created.
  • the pre-planned and current information for example, film contributions, the information from business and trade or contain advertising information, passed on to a transmitter 6 via an intranet 4.
  • the transmitter 6 transmits the information by means of an antenna 7 as a radio signal, which is shown by dashed lines is shown.
  • a plurality of routes go from a depot 8 10, which represent a route network of a transport company.
  • routes 10 12 There are a number of vehicles on routes 10 12 arranged distributed, which drive their routes.
  • the vehicles 12 can be rail vehicles, especially trams. However, can the vehicles 12 also buses of a transport company be, the routes 10 then the roads of the route represent.
  • Each of the vehicles 12 has an antenna 14, which as Receiving antenna is used for each receiving device, to receive the data from the radio signal from which the additional information to be transmitted is derived become.
  • the Antennas 14 at the same time as a transmitting antenna with the Receiving device coupled transmitting device with which the received radio signals continue to be broadcast. This will receive those received from each vehicle 12 Radio signals forwarded so that with the radio signals on the one hand regions can be reached by the broadcaster 6 cannot be reached.
  • Second forms emerging from the individual from the vehicles 12 Radio signals from a network in which the radio signals each exchanged between the individual transmitters become.
  • the vehicles 12 are in the transmission range a vehicle 12 involved in the associated Drive detection area.
  • a direct connection e.g. a Telephone data line
  • From the transmitter 16 at the depot 8 are additional those also received from broadcasting studio 2 or by means of data lines transmit information as Master information on those arranged in vehicle 12 Transfer computer (not shown).
  • Master information on those arranged in vehicle 12 Transfer computer (not shown).
  • the length Residence time allows at the limited data transfer rate in the case of radio signals, the transmission is also large Amounts of data.
  • the data transfer can also be complete or partially using a data line, a local one Network or by means of data exchange on the Computer.
  • Current information is used as additional information compiled in the broadcasting studio 2 and about Radio network broadcast. On the one hand, this becomes general Information in the form of news from politics and Trade and weather forecasts collected. On the other hand transmit current messages from the depot 8. These messages relate, for example, to schedule information, the particular delay reports of vehicles 12 of the operator can include.
  • the additional information is graphics, Images or texts are, these are sent from the computer where appropriate, given positions in the current Program inserted. This can be, for example Actual news or passenger information.
