Definitions

  • the invention relates to a method for transmitting information from a track to a vehicle on the track side point telegrams via a track coupling coil with a starting part and a remaining part to one vehicle-side receiving device are sent when the Track coupling coil is passed by the vehicle in which Direction of travel in front of the track coupling coil regardless of vehicle position in periods loop telegrams for advance information sent out about the content of the data telegrams and the data telegrams as loop telegrams can be used unchanged.
  • the invention relates furthermore a trackside device for carrying out the Procedure.
  • DE-DE 37 02 527 C2 teaches a single-channel data transmission device, those without test telegrams and with one comparatively short read-in time for those to be transferred Data telegrams by using the multiple transmitted telegrams with the same content each an individual, significantly different telegram header becomes.
  • a method and a device of the type mentioned at the beginning are from the prospectus "POINT-BASED INFLUENCE / THE ACCESSION SYSTEM ZUB 100 "from Siemens AG, Order No. A25090-A543-A116-3, PA 03931.0 known.
  • This brochure describes a facility that at crucial waypoints like Signal locations or in front of slow speeds, information from the route to the vehicle. This information can be used to monitor the maximum train speed, Output of optical or acoustic warning signals, braking instructions or emergency braking and / or to monitor the Serve the driver.
  • the situation or signal concept dependent Information is in the form of data telegrams with a fixed data structure from a trackside so-called track coupling coil on a corresponding transmit so-called vehicle coupling coil.
  • Each data telegram begins with one Start head (start part), which is a special sign for Includes synchronization.
  • the starting part is included Remaining part of the user data (for example 64 user bits), one Code monitoring and a stop block includes.
  • the track coupling coil a passive control circuit (50 kHz), an energy receiving circuit (100 kHz) and a transmitter (850 kHz) for sending the data telegrams.
  • a monitoring channel Resonant transmission resonant circuit with 50 kHz
  • the energy receiving circuit takes on the vehicle side via a 100 kHz resonant circuit radiated energy for the supply of the transmitting device on.
  • the data telegrams sent are sent by a corresponding Receiving device in the vehicle coupling coil received to which a vehicle device for further processing and evaluation of the data telegrams is connected.
  • Preliminary information e.g. B. about situations (for example being able to transmit a modified signal term) is one of the Track coupling coil upstream against the direction of travel Send loop provided.
  • the send loop is over one Control circuit can also be acted upon by the telegram generator and sends periodically specific to be labeled Loop telegrams for information about the content of the current data telegram.
  • the invention is therefore based on the object of a method for transmitting information from a route to a vehicle to create where the periodically broadcast Loop telegrams reliably identified as such and from the data telegrams transmitted via the track coupling coil can be distinguished.
  • This task is carried out in a method of the type mentioned at the beginning Art solved according to the invention in that at the beginning of at least one incomplete period in advance Loop telegram is sent, but at least the Start part of the data telegram is sent, and that the so generated Sequence of several starting parts from the vehicle side Receiving device is recognized.
  • a major advantage of the inventive method is that for Generate the data telegrams already existing circuit parts also for generating or marking the loop telegrams can be used. This is only a comparative one simple control required at the beginning the respective period in advance from the vehicle side Start device recognizable start signal (start step) generated in that at least the starting part of the unchanged, data telegram sent out as a loop telegram is transmitted at least twice in succession.
  • the receiving device thus receives a reliably recognizable one specific character to identify a sequence of Loop telegrams without being used as loop telegrams serving data telegrams modified in their bit structure Need to become. This allows existing and proven ones trackside facilities are used; Already installed train control systems can easily be upgraded (upward compatibility).
  • a trackside device for performing the invention Procedure with a telegram generator, the data telegrams generated with a start part and a remaining part, with a track coupling coil with one of the telegram generator charged transmission device for delivering the data telegrams to a vehicle-side receiving device if the vehicle passes the track coupling coil, and with one of the Track coupling coil upstream of the direction of travel, from the telegram generator via a control circuit acted upon transmission loop by the vehicle position independent periodic loop telegrams for advance information sends out about the content of the data telegrams, where the send loop the data telegrams unchanged as Send loop telegrams, according to the invention provides that a control device is provided, which procure in this way is that at least the transmission loop in advance at the beginning of the respective period sends out an incomplete loop telegram, why sending a loop telegram after sending the Starting part of the data telegram is interrupted.

  • Vehicle FZ with a train control system that basically in the brochure "POINT-SHAPED INFLUENCING INFLUENCE ".
  • the section STR is equipped with a trackside device 10, the with a corresponding device 20 on the vehicle cooperates.
  • the device 20 comprises as initially explains a 50 kHz control circuit, a 100 kHz energy transmission circuit and a receiving device based on a Frequency of 850 kHz works.
  • These components are in FIG. 1 collectively referred to as a vehicle coupling coil FZS, to those for evaluation and intervention as required Control units (e.g. brakes) of the vehicle FZ a vehicle computer FR is connected.
  • the trackside device 10 is used for information, Checking and, if necessary, influencing (e.g. braking) the vehicle FZ before a signal 25 and includes to form transmission channels to the corresponding vehicle side Tuned resonant circuits of a track coupling coil GKS.
  • a passive 50 kHz control circuit effects one Current drop in the vehicle-side control circuit Position report.
  • a 100 kHz energy receiving circuit picks up this frequency from the vehicle-side energy transmission circuit radiated energy to a telegram generator and a transmitter operating at 850 kHz with one Transmitter amplifier SV and an antenna ANT ( Figure 2) Food.

  • the track coupling coil GKS is not only the aforementioned resonant circuits and a voltage stabilizer 30 arranged, but also a control device SE and a Telegram generator 32 by a telegram control circuit 34 and one for security reasons double (redundancy) provided and alternately pollable telegram memory 35 is formed.
  • the transmission loop SS is from a transmission loop amplifier SSV and a control logic SL with loop telegrams STEL actable.
  • the control device switches SE one taken from the signal lamp circuit and via the Line 29 of the control logic SL supplied supply voltage U1b for telegram generation as voltage U1 also on the telegram generator 32 through.
  • the loop telegrams are the Transmit loop amplifier SSV via a line 37 from the Telegram generator generated data telegrams depending on the signal concept DTEL fed unchanged.
  • the control logic SL recognizes the end of a data telegram of the data telegram generator 32 and can thus after reaching the desired number to be issued in the respective period Loop telegrams, their specification until the beginning the next period.
