Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • a device is known from DE-AS 20 01 321.
  • the trains themselves are not necessarily equipped with devices for transmitting data, in particular travel location reports, to the route device.
  • the route device cyclically calls up all line sections for the information transfer to the trains and supplies them with information important for the continuation of this train in the event that the section in question is currently being traveled by a train.
  • the trains automatically recognize the section they are traveling on and use the transmitted information telegrams to find the ones that apply to the section they are traveling on.
  • the trains For the self-location of the trains within a route area provided with a line conductor, the trains must be transmitted at the latest when entering the first line conductor section, which enables them to first section and thus the data intended for them. This is done regularly by so-called initial loops, which are fed separately (DE-OS 21 54 913.
  • the object of the invention is to develop the device for linear information transmission known from the preamble of claim 1 in such a way that such a direction-dependent evaluation of location-selectively transmitted LZB data is possible without separate initial loops for the direction-dependent location of the trains in the track.
  • the invention solves this problem by means of the characterizing features of patent claim 1. Because the line conductors are used for the transmission of the travel commands assigned to the direction of travel and also for the transmission of any data to the trains advancing in the opposite direction, the line conductors can be used for Transmission of driving commands also take over the tasks of the previous upgrade loops.
  • FIG. 1 shows the principle of the device according to the invention and in FIG. 2 an embodiment with short loops arranged between the line conductor loops.
  • FIG. 1 shows a section of a single track S.
  • Two light signals SR and SL secure the route in the direction of travel R to the right and in the direction of travel L to the left.
  • line devices SGR and SGL supply associated transmitters SER and SEL with travel command data which they place on line conductors L2R and L2L arranged in the proximity area in front of the light signals.
  • the line conductors are designed in a known manner in the so-called B3 installation. By crossing their forward and return conductors, they preferably form sections of the same size for which the associated route device generates driving commands.
  • One ladder is on a rail foot, the other in the middle of the track; Data is transmitted to the passing trains via the conductor in the middle of the track, which is equipped with the corresponding receiving antennas.
  • the trains From the transmitted driving command data, the trains, even if they know about their respective driving location and direction of travel, cannot yet recognize whether this data should apply to them or to trains advancing in the opposite direction. For this reason, the data to be transmitted are accompanied by identifiers that make it possible to identify the direction of travel on the trains to which the data should apply.
  • the trains In order to be informed about their respective travel location as a prerequisite for the location-selective assessment of transmitted data know, the trains must be provided with information at the latest when entering a LZB area, from which they can recognize the number under which the data of the first LZB section is transmitted; the trains can then determine the numbers of the following sections themselves by updating.
  • the call number of the first section of an LZB area is either communicated directly to a train or it knows that this call number is an agreed lowest or highest call number, and an identifier is to be shown to it which of the two call numbers is actually for the train the first section is used.
  • the line conductor loop L2L provided for the transmission of travel commands for the direction of travel L is to take over the function of an initial loop for the line conductor loop L2R and accordingly the line conductor loop L2R provided for the transmission of travel commands for the opposite direction is to function as a Initial loop for the L2L line conductor loop. Since separate line identifiers are assigned to both line conductor loops, the trains can recognize the direction in which they are moving when they enter a new LZB zone when entering a new LZB zone. They know whether the section they are driving has the lowest or the highest section number. It is also possible to transmit special starting numbers for the following line area. In the individual sections, the trains select the data telegrams intended for them from the direction of travel; the data telegrams intended for the opposite direction are rejected.
  • the line conductor loops via which travel commands applicable to the direction of travel are transmitted, can preferably be used to change unchangeable route data to those advancing in the opposite direction Trains are transmitted.
  • This makes it possible to transmit further data in the run-up to the respective proximity range of a light signal or other route points, which can also be used for vehicle control.
  • slow driving points can be signaled in this way, which a train advancing on a light signal - and only this train, and not a train traveling in the opposite direction - has to take into account before entering the approach area secured by a line conductor and can therefore reduce its speed in good time .
  • a train travels the route in the direction of travel R, it receives the signal-independent data of the route device SGL assigned to this direction of travel associated with this direction of travel and, with a time offset, the travel command data for this section assigned to the other direction of travel L.
  • the train recognizes that it is moving in the direction of travel R from the change of the area identifier from the transition from the past conductor loop L1 into the route area covered by the conductor loop L2L.
  • the train only accepts the unchangeable data transmitted to it with a corresponding direction indicator, which relate, for example, to maintaining a certain speed in the route area it is traveling on.
  • the train determines that it continues to travel the route in the direction of travel R and it now accepts the travel command data transmitted to it by the route device SGR via the conductor loop L2R.
  • the latter first determines that of the signal-dependent and signal-independent data communicated to it via the conductor loop L2R, the signal-independent route data are important in the assumed direction of travel.
  • the train accepts the data transmitted to it depending on the signal and rejects the unchangeable route data then communicated to it.
  • the effort for determining the direction of travel or the transmission of specific telephone numbers and for the additional transmission of fixed data in the device according to the invention is negligible, since the conductor loops required for the transmission of these data are present anyway for the transmission of signal-dependent data.
  • the route devices only memories are required for the provision of fixed data as required, and these memories, in alternation with the memories from which the travel commands to be transmitted are read, are queried by the route device for outputting corresponding data telegrams to the line managers.
  • the device according to the invention can also be used where line points other than light signals are to be secured by line conductors, for example at level crossings or stopping points in train stations.
  • the line conductors provided for transmitting driving commands for different directions of travel do not have to adjoin one another directly. Rather, it is possible that there is a certain distance between the line conductors. However, this distance must not be so great that the trains "forget" the area code transmitted to them in the past route area and say goodbye to LZB operation; if necessary, short repetition loops should be provided to refresh the stored area IDs and possibly further data.
  • An embodiment of this is shown in Figure 2.
  • line conductors are transformer-connected to supply lines V, via which they are alternately called up and supplied with data by the two line devices SGL and SGR.
  • This data contains at least the area identifier of the line conductor L2L or L2R fed by the respective line device.
  • the distance of the short line conductors L4, L5 from one another and from the line conductors L2L and L2R is dimensioned such that it is at most equal to the distance that the trains under LZB control can advance without receiving new travel commands / data.
  • Sections of a line manager must be provided with driving instructions or other data.
  • the maximum number of sections that can be called is limited by the permissible telegram sequence time with which the trains are to be supplied with data.
  • Line devices must be suitable for the line devices Synchronize nete way, for example by mutual monitoring of the transmission level.
  • the trains can update their travel-dependent updated travel location information and thus correct any falsifications as a result of sliding or skidding processes.

Abstract

Pour assurer la transmission continue de données sur des lignes à voie unique, il est prévu deux conducteurs de ligne (L2R, L2L) associés aux deux sens de la marche possibles, alimentés individuellement et destinés à transmettre aux trains des données concernant des ordres de route dépendant du sens de la marche. Chaque conducteur de ligne couvre un secteur individuel. Outre sa fonction de transmission de données concernant les ordres de route, chaque conducteur de ligne est aménagé pour transmettre le numéro d'appel de la première section dans le sens de la marche, à l'autre boucle de câble et/ou un indicatif de zone, grâce auquel un train qui pénètre dans cette première section peut déterminer son sens de marche en liaison avec un indicatif de zone qui lui est transmis localement. Ce système permet en outre la transmission d'autres données spécifiques aux lignes.
