Definitions
- the invention relates to a train control device for wireless transmission of data signals to themselves located in the approach area of at least one railway signal Rail vehicle, the data signals the signal term of the railway signal.
- Such a train control device is from the German Laid-open publication 44 20 215.
- This previously known Train control device points in the approach area a line signal laid in the track on a railway signal, with which data signals wirelessly by inductive coupling between Line conductor and a receiving antenna on the rail vehicle side be transmitted to the rail vehicle.
- the data signals contain the signal term as useful information of the railway signal and are therefore for early upgrading suitable from restricting signal terms.
- a fun based Train control device is shown in DE 196 30 575 A1.
- the invention has for its object a train control device specify which is less maintenance required as the prior art train control device.
- This task is based on a train control device of the type specified at the outset according to the invention solved the features of claim 1.
- a major advantage of the train control device according to the invention is that they don't have a trackside Maintenance required more because there were no antenna devices in the track like line conductors or the like available. This is the case with the train control device according to the invention specifically achieved in that the data signals be transmitted by radio.
- a radio link differs from the beginning in connection with the previously known train control device mentioned inductive Coupling of magnetic fields in that the data signals with "waves" and not with "fields".
- Train control device Because of the large range of the waves is in the train control device according to the invention no more antenna installed in the track bed of the approach area required, which significantly reduces the maintenance effort is; because trackside maintenance work is only still to be carried out on the radio equipment and no longer in entire approach area.
- Another major advantage of the Train control device according to the invention consists in that she’s very safe from vandalism or theft, because there are no line conductors in the track - so high quality Copper lines - more laid that are stolen or damaged could become.
- a third major advantage of the Train control device consists in that directional antennas are provided for radiating the data signals are; the use of directional antennas means that that the transmit energy of the antenna is almost exclusively is limited to the approach area of the railway signal; for one, this reduces the risk of rail vehicles can receive and evaluate data signals on other tracks, which are actually not intended for them, and on the other transmission energy is saved because only the approach area with "Waves" must be irradiated.
- the at least one directional antenna has at least an antenna gain of 10 for its main beam lobe.
- Standard radio devices such as are particularly inexpensive for example DECT, GSM, UMTS or Bluetooth radio devices, so it is considered beneficial if such Standard radio devices in the train control device according to the invention be used.
- control device considered advantageous, if each railway signal has its own radio equipment with at least one in the direction of each Directional antenna aligned with the approach area, wherein each radio device sends data signals that represent the signal term and a signal identifier of the respectively assigned Specify the railway signal. Then in the rail vehicle to provide a receiving device receiving the data signals, the data signals received exclusively uses those data signals that are used as signal identifiers the railway signal on which the rail vehicle is advancing should contain the characteristic debit identifier.
- each radio device as An individual data rate value is assigned to the target identifier, which differs from the data rate values of the other radio devices differs, the radio devices designed in this way are that they match the data signals with that of the target identifier corresponding data rate transmitted, and the rail vehicle side Receiving device is designed such that it is solely from the received data signals uses those data signals with that of the target identifier corresponding data rate are sent.
- the train control device according to the invention can be For example, for the early upgrading of driving restrictions Use signal terms.
- the invention also relates to a method for wireless transmission of data signals to oneself in the approach area at least one railway signal Rail vehicle, the data signals the signal term of the railway signal.
- FIG. 1 shows a track system 5 with, for example, 4 railway signals 10, 15, 20 and 25, each one track are assigned to the track system 5; the first is concrete Railway signal 10 a first track 30, a second railway signal 15 a second track 35, a third railway signal 20 a third track 40 and a fourth railway signal 25 assigned to a fourth track 45.
- the four tracks 30, 35, 40 and 45 are with three switches 50, 55 and 60 with connected to a feed track 70 via which rail vehicles the four tracks 30, 35, 40 and 45 can get.
- In the Figure 1 is the direction of travel of the rail vehicles with a Arrow marked with the reference numeral 80.
- a feed device 70 is arranged on the feed track 70 for example by radio or using a line cable Exchange passing signals of rail vehicles can.
- Track area of tracks 30, 35, 40 and 45 should hereinafter referred to as the approach area of these tracks.
- the railway signals 10, 15, 20 and 25 are each with a Radio equipment equipped, the data signals towards of their respective approach area.
- the radio devices each equipped with a directional antenna, in the direction of the approach area of the assigned railway signal are aligned; this is shown in FIG. 1 the main lobes 140, 145, 150 shown in dashed lines and 160 of the directional antennas are shown schematically.
- the arrangement according to FIG. 1 can be premature, for example Upgrading driving-restricting signal terms are used that the rail vehicles previously - d. H. for example on the feed track 70 by the transmitting device 90 - have been transferred.
- the transmitter 90 becomes the rail vehicle transmits a signal identifier, namely the signal identifier from the railway signal on which the rail vehicle is pointing to move.
- a signal identifier namely the signal identifier from the railway signal on which the rail vehicle is pointing to move.
- the Rail vehicle so an information signal with the signal identifier Q transmitted for this first railway signal 10.
- the rail vehicle then has the information which railroad signal it will approach.
- the rail vehicle is then due for further travel the corresponding turnout of turnouts 50, 55 and 60 on the first track 30 and thus in the approach area of the first railway signal 10 arrive.
- the rail vehicle with its rail vehicle side Receiving device from the radio device of the receive first railway signal 10 transmitted data signals; but since - as shown in FIG. 1 - the railway signals 10, 15, 20 and 25 one relative to the size of the main lobes 140, 145, 150 and 160 are very close to each other have, it will happen that the rail vehicle will not only the data signals of the first railway signal 10 but also the data signals of the other railway signals 15, 20 and 25 is received.
- the rail vehicle After receiving the data signals, the rail vehicle chooses then in a manner known per se (cf. for example the introduction specified publication) the correct data signals from, taking into account that of the transmitting device 90 transmitted signal identifier Q. This is without further possible because the signal identifier - as explained above - indicates that the rail vehicle is on the first railway signal 10 approaches and the rail vehicle therefore "knows" that it only the data signals with the signal identifier of this first Rail signal 10 may use.
- the data signals can be transmitted in DECT, Bluetooth, UMTS or GSM standard. Does that happen Transmission of the data signals in a frequency division multiplex method, for example, every railroad signal and so that each signal identifier has a predetermined transmission frequency be assigned. After receiving the from the transmitter 90 sent signal identifier Q would then be in the rail vehicle the information is available on which frequency the data signals of the "correct" railway signal are sent be, so that the receiving device then, for example filter out those data signals by means of a filter device can with that of the signal identifier Q of the first Railway signal 10 corresponding frequency are sent.
- the transmission of the data signals can also be done in Time-division multiplexing; so the radio equipment the railway signals with one for all radio equipment identical timing are supplied; the radio equipment would then only be in the predefined ones - ie reserved - send time slots data signals.
- a third variant for transmitting the data signals is now explained in connection with Figures 2 and 3:
- all radio devices send their data signals with the same carrier frequency, completely independently from each other - without a central clock.
- the data signals have a predefined telegram structure; a data telegram D with an embodiment for a The upper part of the figure shows the specified telegram structure 2.
- the data telegram D has "1" bits and a data rate of "m" on.
- the lower part of FIG. 2 shows the transmission of the data telegrams D over time; one recognizes that always n (n for example 3) telegrams directly one after the other be sent. Then there is a transmission pause ATP inserted, for example, six times the length of the telegram of the data telegram D can correspond.
- FIG. 3 shows the time course of the data signals or the data telegrams for all railway signals 10, 15, 20 and 25; where is the time axis of the first railway signal 10 in the figure with the term "Sig1", the time axis of the second railway signal 15 with the term “Sig2”, the time axis of the third railway signal 15 with the term “Sig3 and the time axis of the fourth railroad signal 20 with the Marked the term "Sig4".
- the data rate of the data telegrams serves as a signal identifier for the respective radio device or for the respective Railway signaling.
- FIG. 3 shows that after a period of time, which corresponds to only a few telegram lengths of data telegram D, comes to time intervals ⁇ t1, ⁇ t2, ⁇ t3, ⁇ t4, ⁇ t5, in which only one radio device transmits; even if - as shown in Figure 3 -
- the four radio devices at a time t 0 "in time send ".
- the frequency of these time intervals ⁇ t1, ⁇ t2, ⁇ t3, ⁇ t4, ⁇ t5 or the time interval between the time intervals depends on the number of radio devices or the railway signals, from the telegram length - i.e. the number "n" of the bits of the data telegrams D -, on the length of the transmission pauses between the data telegrams and the data rates "m" of the radio equipment or the ratio of the data rates to each other.
- a located in the approach area of the railway signal 10 Rail vehicle is - because of the partial spatial Overlap of the transmission ranges of the radio devices - during of advancing on the railroad signal 10, in part the data signals several different radio devices at the same time receive; this leads due to the identity of the transmission frequency or carrier frequency of the radio devices that the received data telegrams cannot be used.
- the Rail vehicle must therefore on the time intervals ⁇ t1, ⁇ t2, ⁇ t3, ⁇ t4, ⁇ t5 wait in which only one Radio device sends. If this is the case, the measures Receiving device on the rail vehicle side according to any one Data rate measurement method the data rate at which the received data telegram was sent.
- the rail vehicle recycles the received data telegram; otherwise it will be discarded. In the latter case, the rail vehicle must then on the wait for the next time interval, in which a single data telegram is sent.
