Definitions

  • the invention relates to a device for monitoring the presence of rail vehicles within certain track sections, in particular in drainage systems for measuring the free track length.
  • the invention has for its object to provide a device for monitoring the presence of rail vehicles within certain track sections, in particular in drainage systems for free track length measurement, which detects the presence of rail vehicles within the track section in a digital manner with little technical effort, without environmental influences or changing Boundary conditions influence the measurement result.
  • the solution to this problem by the invention is characterized in that the track section is divided into a certain number of immediately consecutive subsections, that at the beginning of the track section determined by the direction of travel of the rail vehicles, a digital track level meter and at the end of each subsection a digital transmitter-receiver.
  • Module with a specific address is arranged that the transmitter-receiver modules are connected by a common line to the track level meter and by means of their address from this for feeding an AC voltage in the low voltage range at a defined frequency into the track section and that the Track level meter queries the voltage fed in by the individual transmitter-receiver modules at the beginning of the track section and transmits the result, which is dependent on the presence of wheel sets of rail vehicles that connect the rails of the track section to one another in an electrically conductive manner, and is assigned to the respective subsection to an evaluation circuit.
  • the device according to the invention it is not necessary to divide one of the rails of the track section by means of separating joints which effect electrical insulation. In addition, the considerable technical effort required to attach the separating joints is eliminated. Since the alternating voltage fed by the transmitter-receiver modules into the track section, in the low-voltage range, i.e. below 42.4 volts, with a frequency between 10 and 100 kHz is not measured analogously by the track level meter according to the invention, but is only checked as to whether it At the beginning of the track section, there is a digital measurement method in which environmental influences, different bedding resistances of the rails and changing contact resistances between wheel and rail have no influence on the measurement result.
  • the device according to the invention thus results in a particularly reliable monitoring of the track section, its division into immediately successive subsections giving a high and reliable information value. Since the respective activation of the transmitter-receiver module assigned to a specific subsection takes place via the line common to all the modules by the address of the respective module from the track level meter and the position of the activated one Known subsection, the device according to the invention provides an exact statement as to whether and how many subsections - starting from the track level meter - are free of rail vehicles. In the case of drainage systems in particular, the track length free of rail vehicles can thus be determined exactly.
  • the frequency of the voltage fed into the track section by the individual transmitter-receiver modules can vary be. This is possible, for example, in that the frequency of successive modules fed into the track section differs by 5 or 10 kHz in each case.
  • the voltage received by the track level meter therefore results in an assignment to the respective subsection depending on the respective frequency.
  • a further track fill level meter can be arranged in a further development of the invention at the end of the track section, which alternately with the track fill level meter arranged at the beginning of the track section via the common line, the transmitter-receiver Module activated and the determined results passed on to the evaluation circuit. This is a determination of the The presence of rail vehicles within the track section is possible regardless of the direction of travel by querying from both sides of the track section.
  • each transmitter-receiver module can additionally be designed as a receiver of the voltage fed into the rails of the track section by the other transmitter-receiver modules, and that The result of the test initiated by the track fill level meter can be passed on to the line.
  • the track fill level meter can be passed on to the line.
  • the invention proposes to galvanically separate both the transmitter-receiver modules and the track level meter (s) from the rails of the track section. In this way, damage to the device according to the invention by currents occurring in the rails of the track section can be avoided.
  • the track section 1 to be monitored for the presence of rail vehicles in the exemplary embodiment is divided into a total of n subsections 2 1 to 2 n without these immediately successive subsections 2 being separated from one another by separating joints or the like.
  • a track level meter 3 is connected to the two rails of track section 1, which in turn is connected to the power supply U.
  • a block diagram for a preferred embodiment of the track level meter 3 is shown in FIG.
  • a transmitter-receiver module 4 1 to 4 n is connected.
  • a preferred embodiment of such a transmitter-receiver module 4 is shown in the block diagram according to FIG.
  • Each transmitter-receiver module 4 is connected to the neighboring modules and the track level meter 3 by a multi-core line 5.
  • Each transmitter-receiver module 4 has a specific address, so that it can be specifically addressed and activated by the track level meter 3 via line 5.
  • an AC voltage in the low voltage range with a defined frequency is fed into the track section 1.
  • the voltage is preferably below 42.4 volts.
  • the frequency is preferably between 10 and 100 kilohertz.
  • the voltage fed by these modules 4 into the track section 1 can differ from module to module by an increasing or decreasing frequency, for example in steps of 5 or 10 kilohertz.
  • the monitoring process is initiated by the track level meter 3 by activating the adjacent transmitter-receiver module 4 1.
  • This transmitter-receiver module 4 1 feeds an AC voltage with a certain frequency into the rails of the track section 1. Since there is no rail vehicle in the subsection 2 1 in the exemplary embodiment according to FIG. 1, the track level meter 3 determines the voltage fed in by the transmitter-receiver module 4 1. It is not the value of the voltage that is important here, but only the presence, so that environmental influences do not distort the digital measurement result.
  • the track level meter 3 accordingly passes the result on to an evaluation circuit 8, which thus recognizes that there is no rail vehicle in the subsection 2 1.
  • the transmitter-receiver modules 42 to 4 n-1 are then activated. Since there is also no wheel set of a rail vehicle in these subsections 22 to 2n -1 , these voltages fed one after the other are determined by the track level meter 3 and the digital measurement result is passed on to the evaluation circuit.
  • This wheel set 6 connects the two rails in the lower part cut 2 n electrically conductive with each other, so that due to the resulting short circuit in subsection 2 n, the voltage emitted by the transmitter-receiver module 4 n does not spread to the connection points of the track level meter 3 at the beginning of track section 1. Since the voltage emitted by the transmitter-receiver module 4 n cannot be determined by the track level meter 3, the downstream evaluation circuit determines that there is a rail vehicle in subsection 2 n .
  • the device is therefore particularly suitable for carrying out a track free length measurement in drainage systems.
  • a second wheel set 7 is located, which is located in the subsection 22.
  • the voltage fed by the transmitter-receiver module 4 2 into the track section 1 would no longer be able to be determined by the track level meter 3.
  • from the transmitter-receiver modules 43 to 4 n supplied voltages can be due to this wheel set 7 do not spread up to the beginning of the track section 1, so that in this case the downstream evaluation circuit outputs as a result that the track section 1 in the direction of travel starting is occupied with the subsection 22.
  • each transmitter-receiver module 4 is additionally designed as a receiver of the voltage fed into the rails of track section 1 by the other transmitter-receiver modules 4.
  • the result of the test initiated by the track fill level meter 3 is passed on via line 5 to the latter.
  • the track level meter 3 controls the adjacent transmitter-receiver module 4 1, so that this feeds an alternating voltage with the frequency corresponding to the transmitter-receiver module 4 1 into the rails of the track section 1. Since the subsection 2 1 is free of rail vehicles in the exemplary embodiment, this voltage is perceived by the track level meter 3. Now the transmitter-receiver module 42 is activated to determine whether the voltage emitted by the transmitter-receiver module 41 from this Sen the receiver module 42 can be determined. Since the wheel set 7 shown with dashed lines is located in subsection 22, the transmitter-receiver module 42 cannot determine any such voltage. There is accordingly via line 5 the message to the track level meter 3 that the subsection 22 is occupied.
  • the transmitter-receiver module 42 is activated by the track level meter 3 and sends its, preferably a different frequency, alternating voltage into track section 1.
  • the transmitter-receiver module 41 also activated by track level meter 3, can transmit this voltage as a result of the wheelset located in subsection 22 7 do not determine, so that the previously reported busy message from the transceiver module 4 1 is confirmed via line 5.
  • the following transmitter-receiver modules 43 to 49 can determine the voltage fed by the transmitter-receiver module 42, so that the subsections 23 to 23 are reported as vacant. These messages are confirmed several times when the transmitter-receiver modules 43 to 49 then feed their voltage at a predetermined frequency into the rails of track section 1 and are switched to reception one after the other.
  • the evaluation circuit 8 can be seen, which addresses a specific feed-in point via a serial output stage 9 and a multi-core control line.
  • the recorded AC voltage is fed from the rails of the track section 1, for example galvanically isolated by means of a transformer, to a bandpass filter 10.
  • the voltage in the target frequency range is offered to the microcomputer in the evaluation circuit 8 for evaluation via a rectifier 16.
  • the operating voltage for the transmitter-receiver module 4 is provided from the line via a stabilization stage 11.
  • the decoupled telegrams are with a set address in one Comparator 12 compared and generated a pulse of defined length in case of equality.
  • a frequency generator 13 is activated for the duration of the pulse and the feed into the rail of the track section 1 is carried out via a galvanic isolating stage 14 with a downstream low-pass filter 15.
