Definitions

  • the invention relates to a device for information transmission in train control.
  • a train protection system with line-shaped signal transmission between train and route in which a control center transmits information to the trains traveling on the route about the number of free sections ahead in each case or the speed values permitted for the onward journey.
  • the control center calls the vehicles location-selectively via the section numbers of the track sections they have occupied and transmits the data it has developed for the vehicles to the vehicles.
  • the vehicles acknowledge receipt of this data to the control center, which recognizes the possibly new location of the vehicles based on these acknowledgment messages and includes them in the calculation of the data to be sent to the vehicles during the next pass.
  • the advantage of this known system for influencing the train is that the control center is informed at all times about the location of the vehicles, so that it can address the vehicles in a targeted manner via the sections they have registered and supply them with data; No data is transmitted for the sections that are not reported as busy.
  • This type of information transmission in the control center requires seamless tracking of the vehicles and it requires means on the vehicles for self-location and for comparing the section number determined by the vehicle itself with the section number transmitted by the control center.
  • the vehicles used on routes with point-like train control are usually not equipped for such intensive data processing.
  • the same magazine reports on page 257 about a digital security system with controlled conductor loops, in which individual sections of a route are assigned short conductor loops, via which a control center can transmit information to the vehicles traveling on the route.
  • the control center receives information about the respective location of the vehicles in that the vehicles continuously feed a signal voltage into the conductor loops below them and the control center cyclically polls the conductor loops one after the other for the coupled signal voltages. Upon receipt of such a signaling voltage, the control center transmits to the vehicle in question certain information it has developed that relates to the vehicle's onward journey.
  • Remote-controlled switches are used for cyclical switching on of the individual conductor loops. Due to the constant feeding of the signaling voltages into the conductor loops, the vehicles need separate transmitters for the signaling voltages and command receivers for the instructions of the control center; The transmitter and receiver are constantly switched on.
  • the object of the invention is to provide a device for information transmission in train control, which manages the quasi punctiform data transmission to the vehicles with as little effort as possible for the track devices.
  • the drawing shows: in the upper part a track device for quasi punctiform train control and in the lower part a control center, which causes the track equipment assigned to it to transmit important data to the vehicles for the onward journey of the vehicles traveling on the route.
  • control center LST which can also be designed as a line device
  • several track devices for train control are connected via coaxial cables K1 to Kn; the control of the individual track devices takes place via a multiplexer M, which can be set by a central control part ZS of the control center.
  • the control center uses the central control section and the multiplexer to cyclically call up the vehicles that are currently in the sphere of influence of the individual track devices. This call exists e.g. in two telegrams that are identical in terms of content, but possibly represented in different ways, which are generated by frequency shift keying.
  • the control center briefly goes to reception. If the call is picked up by a vehicle, it acknowledges the call via the line manager and the track device to the control center.
  • the control center thus knows about the presence of a vehicle provided with transmitting / receiving devices in the area of action of the track device in question and then causes the track device to serially transmit data held in the track device to the vehicle via the line conductor.
  • the control center should first send a continuous signal.
  • the continuous signal is provided by the telegram generator TEZ to the control center and fed to the multiplexer M via a switch S6 set by a central control part ZS, an amplifier V5 and a capacitor C2; From there it first reaches all track devices connected to the control center via the coaxial cables K1 to Kn.
  • loop control modules of the track devices e.g.
  • the continuous signal is decoupled via a capacitor C1 and fed into the associated line conductor L of limited length via a switch S2, an amplifier V1 and a hybrid circuit G for decoupling transmission / reception voltages.
  • the continuous signal fed into the line conductor can be used in a known manner on the vehicles for self-location.
  • the control center When a vehicle in the area of influence of a track device is called up, the control center causes the permanent signal to be briefly switched off, at least for the track device that is switched on. Furthermore, if it is designed for this purpose, it causes special call telegrams to be issued which are intended to cause this vehicle to submit an acknowledgment message.
  • the output of this acknowledgment message by the vehicle can be made dependent on repeated receipt of the call telegrams issued several times in succession for this purpose; the call telegrams are generated by the telegram generator TEZ of the control center, preferably by frequency shift keying.
  • the control center can be designed so that it primarily or exclusively calls up those track devices and supplies them with continuous levels and / or call telegrams of which they know that they will be passed shortly by a vehicle traveling on the route.
  • control center If the control center is not set up to issue call telegrams, the absence of the continuous signal on a vehicle passing through the track device must trigger the output of the acknowledgment message. After calling up a vehicle, the control center is ready to receive.
  • the central opens for reading the receipt message Control part ZS of the control center a switch S4, via which a DC voltage + U was previously transmitted to the track device G1. This DC voltage is coupled in and out on the associated coaxial cable via chokes D1 and D2.
  • the decentralized control part DS in the loop control module SS-BG of the track device recognizes from the absence of the DC voltage that the control center is waiting for the receipt of acknowledgment messages and then closes the switch S3 via which these acknowledgment messages will run; at the same time it opens switch S1 in the transmission branch of the track device.
  • the line conductor L has a limited extension of, for example, a few tens of meters. If there is a vehicle with transmitting / receiving devices in the area of influence of the line manager L and this vehicle has correctly received the two call telegrams from the control center, for example, or has detected the absence of the continuous signal, it will issue an acknowledgment message via the track device to the control center.
  • the control center is thus ready for the expected acknowledgment message, which it can only receive if a vehicle equipped with transmitter / receiver devices is actually in the area of influence of the track device.
  • the acknowledgment message from such a vehicle is fed to the control center via the switch S5 and the amplifier V4 of the telegram evaluation TAZ.
  • the receipt of the acknowledgment message informs the control center that a vehicle is within the sphere of influence of the switched-on track device.
  • Vehicle-specific data can be implied in the receipt message.
  • the control center initiates the output of the data held ready for the vehicle in question in the track device.
  • the central control part ZS closes the switch S4; at the same time it opens switches S5 and S6.
  • the decentralized control part of the loop control module is informed that it now has to send the data impressed on the track unit to a vehicle via the line cable.
  • the track unit is supplied with energy, for example, via the DC voltage + U applied by the control center.
  • the central control part in the control center initiates the closing of switch S4 and the switching of the multiplexer M to control the following track device after a predetermined time has elapsed since the call.
  • the predetermined period of time in which the central control part of the control center waits for an acknowledgment message to arrive can be much shorter than the period of time required for the complete receipt of an acknowledgment message; it is essentially determined by the switching times of the switching means involved in the data transmission both in the control center and on the track device.
  • the time period required for the transmission of acknowledgment messages e.g. 2 ms is so short that a vehicle passing the track device can clearly distinguish between the absence of the permanent signal and a long-term level drop when crossing a line conductor crossing point, i.e. the highly precise location of the vehicles is not disturbed by the data transmission procedure.
  • the decentralized control part of the loop control module issues a connection request to a telegram module TB of the track device G1 by switching on the DC voltage + U to the coaxial cable K1.
  • This telegram module is used to convert information derived from the respective signal term of an associated light signal S via a signal module SB into a corresponding data telegram and the track coupling coil GKS of the track device feed.
  • this data telegram can also contain further data which, for example, designate the track device in question or its location.
  • the data provided serially by the telegram module TB is sent as a data telegram via an amplifier V3, a capacitor C3, a switch S1, an amplifier V1 and the hybrid circuit G to the line conductor L and is transmitted from there to the coupling coil of the vehicle passing by.
  • the data provided by the telegram module are transmitted several times in succession as data telegrams. This makes it possible to ensure secure, because multiple data transmission, even at high driving speeds.
  • the power supply for the track device for transmitting the data telegrams is provided by the control center via the coaxial cable.
  • the receipt of an on-board acknowledgment message for the receipt of the transmitted data leads in the decentralized control part DS of the loop control module to the opening of the switch S3 and the closing of the switch S2.
  • the initial state of the loop control module is thus reached again, so that data can again be transmitted to the passing vehicles when the control center subsequently connects.
  • control center can already control the next track device via the multiplexer and supply it with call telegrams for the detection of passing vehicles.
