Definitions

the invention relates to a method for informing passengers in one Traffic system with a large number of vehicles and stops and with one Message system, said first output device on at least one Stop for issuing passengers intended for passengers at this stop Has information.
the invention further relates to an information system for Inform passengers in a variety of vehicles as well as stops having traffic system, the information system being a message system and a first output device at at least one stop for output by the Message system generated or received by this, for passengers at least has information provided at this stop.
Stops mentioned generally refer to places where the passengers of the Entry and exit to one of the vehicles is permitted. In particular, with one railway system, the stops are therefore also individual platforms of a train station.
acoustic information is also sent to the passengers, for example passed on.
the passenger is informed by means of loudspeaker announcements Continuation options, schedule changes, etc. informed.
the object of the invention is to provide the passenger with timely and complete information to supply the stop, in particular the times required for information the stops should be largely minimized.
the task is intended in particular in With regard to low effort and the highest possible security for receiving more important Information to be resolved.
a second output device is provided in at least one of the vehicles, that the second output device before transmitting the information to the passengers at the stop provided information about a wireless transmission link with the Message system is connected and in that vehicle-internal information Occurrence of a signal is passed to the second output device and this Signal the output of the information transmitted via the second transmission link is prevented.
the information is preferably output simultaneously, which also causes disruptive echo effects be avoided.
the passenger Because of the second output device connected to the transmission link inside the vehicle, the passenger is already with the vehicle before getting out Information as supplied at the bus stop. Therefore, for example, in the case of an announcement careful timing between opening the door and getting out is unnecessary. A Announcement reaches the passenger significantly due to the higher quality of communication more secure than other prior art information technologies.
Message system is operated as a public address system by issuing the Information on the output devices is advantageously carried out acoustically. Thereby information is captured much better.
the key could then be a correspondingly designed device in the vehicle only on the address information intended for this vehicle and into the interior of a Deliver the vehicle. This provides technical options to keep passengers from to relieve unnecessary information. Next the number of necessary Transmission routes restricted, which reduces the technical effort and thus the costs be kept low.
the interruption of the connection can be carried out particularly advantageously according to a preferred one
Develop the invention technically solve if the connection on the Transmission route interrupted after the vehicle has left the stop is and the connection only over the transmission link when approaching a Vehicle is made to the stop. Then every stop becomes one Assigned transmission route. Establishing and interrupting the transmission link In particular, it does not require any additional electronics if the transmission link is one has limited range. Then there is the making and breaking of the connection given only by the limited range of the transmission link. Also according to this Further development of the invention reduces the effort.
personnel for Announcements can be saved if the information after the connection is established automatically transmitted over the transmission link and on the first and / or second Output device is output.
connection can, for example, be established automatically via a sensor, which signals the electronics in the station area that a train is arriving to the Information should be transmitted.
a device in which the advantages of the method and its further developments are realized are based on the prior art mentioned at the beginning by a second Output device for outputting those intended for the passengers at this stop Information in at least one of the vehicles connected to an in or on the vehicle located receiver for information transmission is connected, and a transmitter marked at the stop, the messaging system with the second Output device via a wireless formed by means of the transmitter and the receiver Transmission distance of limited range for the transmission of the for the passengers At least this stop provided information is connectable if that Vehicle is within range of the transmitter. There is one Control device is provided, the in the presence of vehicle-internal information Forwarding only this information to the second output device is trained.
the driver uses a microphone, an amplifier and a loudspeaker system, i.e. with an internal vehicle Information facility that can inform passengers directly.
the effort is internal to the vehicle Information device provided with an output device, the second Output device is operable.
the microphone mentioned and the amplifier is connected to the speaker system in the car so that a separate second output device can be saved by the output Acoustic information is provided via the same loudspeaker used by the driver also announcements directly to the passengers.
the internal Information device connected to a transmitter located in or on the vehicle as well further provided at at least one of the stops, a receiver for which the Another transmission path can be set up in the opposite direction with the transmitter Information from the information device can be transmitted to the messaging system and at the first output device can be output.
the vehicle driver can also provide information, for example transmit the boarding and disembarking passengers. It is with some transport companies e.g. It is customary to only let passengers board at the driver's door at night so that The driver can check the tickets straight away. In this case, they are common Announcements by the driver are required in order to alert the boarding passengers make sure that they should only use the front door of the bus. According to this Further development of the invention, the vehicle driver can already make this notification Approach the passengers waiting at the stop so that longer ones Waiting times can be saved. Above all, this increases the effectiveness of the Traffic system. Announcement personnel at small stations may be able to do this be saved.
the Information device has an information store and a device according to Structure of the further transmission path the stored information from the Information store transfers to the messaging system at the stop.
the expert can also use known circuits for this.
the transmission path only has to have a short range, you are not necessarily relies on radio transmitters and radio receivers to set up the transmission link.
the transmitter and receiver are particularly insensitive to interference preferred development of the invention for transmission by means of optical signals.
one is off Suitable for infrared transmitters and infrared receivers.
stops should also be understood to mean platforms are. There are therefore several stops at train stations as defined adjacent. A similar situation arises at bus stations.
each transmitter is limited to a solid angle range and with respect its directional characteristic is aligned so that in every vehicle accessible Only one transmitter can be received in the room area.
the Directional characteristic can be realized, for example, that for one A parabolic mirror is provided for the radio transmitter. A particularly small effort will however achieved when the transmitter, for example, at a stop within a metallic shelter is arranged so that this shelter itself in the radiation shields large solid angle ranges and thus determines the directional characteristic.
the following developments of the invention deal with how the individual Signal sources with simultaneous occurrence of both information that is inside the vehicle, for example via a microphone, as well as those generated by the receiver is delivered, are switched to the second output device.
a control device is provided in the vehicle, for a Switch either the vehicle's internal information or that from the receiver Information is formed on the second output device.
the invention is further developed in this regard in that the Control device can be acted upon with a signal with which only vehicle-internal information with simultaneous occurrence from the recipient Information can be switched to the second output device.
the in-vehicle Information takes precedence over one from the messaging system over the link sent. This enables the train guide, for example when dangers occur, to warn immediately, without the end of one over the transmitter and receiver in the Must wait for the vehicle to get the information. Because of this measure, the Security of a traffic system increased.
This information comes from the same source and will wirelessly transmitted.
announcements can be made automatically or by personnel be transmitted. Announcements can also be made automatically, for example from the vehicle off, are triggered.
the transmission path is bidirectional, the Source can also be located in the vehicle.
the figure shows an information system according to the invention in a schematic manner with which the method shown can be carried out in a particularly simple manner.
the system shown can be used for both buses and trains.
the exemplary embodiment is only used for the web on the basis of one in FIG. 1 shown vehicle 1, schematically drawn as a railcar with a trailer, described.
vehicle 1 schematically drawn as a railcar with a trailer, described.
the transfer to bus systems can easily be done by a person skilled in the art carry out.
a messaging system 3 is provided, which is connected via a line 4 to a central office is connected, from which in particular acoustic information to the stop 2 is sent.
the vehicle 1 also contains an information device consisting of a microphone 6, a a control device 7 containing a microphone amplifier and a loudspeaker 8 consists. By means of this information device, the vehicle driver can within the Inform passengers of vehicle 1.
the transmitter 9 is in the embodiment Radio transmitter whose radio waves are directed only into a limited solid angle range, however, such that a vehicle located at stop 2 has radio waves from it can receive.
the directional characteristic of the radio waves can be determined, for example, by a appropriate training of the antenna can be realized. If the stop 2 however has a metallic shelter, the transmitter 9 can also be installed in this the shelter itself provides a corresponding directional characteristic.
the transmission link is only in operation when the vehicle 1 to the stop 2, as shown schematically by the arrow 11, drives up. Accordingly, the transmission link is interrupted again when that Vehicle 1, as indicated by arrow 12, leaves stop 2.
the transmission path is therefore only active for vehicle 1 in the vicinity of stop 2. Thus, especially at train stations due to the shelter given Polar pattern interference between transmissions at different stops 2 or Avoided platforms.
the acoustic output on the speaker Radio information about the transmitter 9 and receiver 10 Transmission path also transmitted to the control device 7.
the control device 7 There are the received radio signals demodulated and in a suitable manner with the signal from Microphone 6 processed, so that the speaker 8 optionally according to the priority also the received signal as acoustic information in the passenger compartment of vehicle 1 becomes audible. Should the signal from the microphone 6 also together with the demodulated A summing amplifier can be used to make the radio signal audible be used.
the reduction of the vehicle 1 caused by the approach Transmit power of the transmitter 9 is detected in the exemplary embodiment and generates a signal, which is used within the message system 3 as an indicator that a Vehicle has reached stop 2.
the Message system 3 can be supplied from the central office via line 4, that can Message system access to an information store 13 in order to approach the Vehicle 1 automatically sends notifications to passengers waiting at stop 2 to transmit the loudspeaker 5 or in the vehicle 1 to the loudspeaker 8.
the name of the stop from information store 13 into vehicle 1 to transmit and make this audible through the loudspeaker 8 in the vehicle 1.
the control device 7 is also designed so that with the transmitter 9 located there Radio signal is generated, which is modulated with the announcements from the microphone 6 to transmit this to a receiver 15 connected to the message system 3.
An amplifier is also present in the message system 3, in particular with the same priority Summing amplifier, provided in the same way as in the control device 7 described, the information received by the receiver 15 according to the selected priority forwards directly to the loudspeaker 5. This enables the vehicle driver, for example Provide information such as "please resign, the doors are now closed” or “just get in at the front door”. Furthermore, can also automatically from the vehicle Information is transmitted to the message system 3. That is why Control device 7 is also connected to an information store 17.
the information store 17 consisted of a cassette tape recorder with endless belt on which the lane number and the destination were stored.
the Information from this information store 17 is sent to the Loudspeaker 5 transmits when vehicle 1 approaches stop 2.
a control signal from the receiver 10 is used, which at Reception of a radio wave emitted by the transmitter 9 is generated.
the control device 7 detects the absence of the radio signal of the transmitter 9 and transmitter 14 is turned off to avoid interference at other stops.
FIG. 2 is an embodiment of a control device 7 with respect to Management of vehicle-internal information coming from the receiver 10 is shown.
the receiver 10 and the microphone 6 are shown on the left side of FIG. Before that However, electrical signals received by the microphone 6 are transmitted to the loudspeaker 8 are switched, these are preamplified by a preamplifier 18. Subsequently the analog signals generated by the preamplifier 18 or by the receiver 10 an electrically controlled switch 19, for example a relay, alternatively to the Input of an amplifier 20 is placed, the output of which is then at the loudspeaker 8 connected. The two analog signals are switched by a signal O from a circuit 21.
the circuit 21 is implemented with a TTL logic, that is, a open input means a logic state 1.
a talk button 22 of the microphone 8 is connected.
the driver wants to the microphone 6 and the loudspeaker 8 pass on information to the passengers he previously the button 22, so that with the button 21, the switching state of the switch 19 on the Circuit 21 is defined.
input A of circuit 21 receives also a signal that information is present at the output of the receiver 10.
a circuit 23 is provided, which originates from the receiver 10 AC voltage rectified, integrated and a logic signal via a threshold switch generated to indicate the presence of information.
This logic signal is after The recipient's information is delayed by about two seconds switched off, this time being selected so that speech pauses when receiving a Signals do not lead to a switch of the switch 19 via the circuit 21. Thereby becomes an essentially undisturbed information transfer to the loudspeaker 8 ensured.
the circuit 21 is also supplied with a signal L, which originates from the receiver 10. in the Normally the signal L is logic zero. In this state, the switch 19 only actuated when a logic signal from circuit 23 is present at input A, however the talk button 22 is not pressed. However, if the talk button 22 is pressed, this receives Microphone 6 Priority for voice output on the loudspeaker 8.
the driver can For example, fire in the vehicle, immediately the one received over the transmission link Interrupt information and report the danger. This increases the security of the Traffic system.
the receiver would have the increased circuitry given priority for the Turn off speech output via the microphone 8. It is intended that A binary code can be sent to receiver 10, which serves in receiver 10 to to set the signal L to 1. This signal L raises the priority of the microphone for the Issue when danger arises.
the transmitter In the event of important danger messages from outside the vehicle, the transmitter is used a binary pulse sequence is transmitted, which is interpreted accordingly by the receiver 10, so that this generates the corresponding switchover signal L. This signal will be automatic reset to logic zero when the message is finished, so that the control device 7 after the message is back in the state in which the microphone transmission Has priority.
the schematically illustrated embodiment shows with what simple means and with how little effort an information system according to the invention can be implemented.
the low effort it increases the comfort for the unexpected Passengers, however, also relieve the service personnel of the traffic system, above all due to the information store 13 and 17 and the possible automatic Transmission of information. It is expected that the resulting relief of the driver indirectly, since he can concentrate his entire attention on the traffic, also leads to fewer accidents. Service personnel can also be found at train stations can be saved because fewer passengers have to request information.
the message system 3 with information control device 7 and information store 17 can also be designed as a computer, the information to be output e.g. are stored digitally on a hard disk.
the receivers 10 and 15 as Infrared receiver and transmitters 9 and 14 are designed as infrared transmitters.
