Definitions

  • the invention relates to a device for track vacancy detection, train location and speed measurement according to the preamble of claim 1.
  • axle counting circles are used in certain cases (long track sections, steel sleepers) for track vacancy detection.
  • a track section to be monitored for its occupied state is limited by so-called metering points.
  • the metering points usually consist of two axis detectors, which are offset against each other on the rails of a track, and are able to individually detect the axes of a train passing the metering point and also determine their direction of passage.
  • the track section is then released when the number of axes retracted into the section corresponds to the number of axes extended out of the section.
  • the necessary number of axles comparison is carried out in the signal box in a special axle counting device, to which axle impulses of the metering points delimiting the track section are fed.
  • axle counting devices used today are sensitive to interference from electromagnetic interference and to interference from actuated magnetic rail brakes. Already a single faulty pulse can keep a track section that has been cleared occupied occupied and can thus block it, unless complex corrective measures are provided. In the event of a blockage, the fault must be remedied by the dispatcher after thorough examination of the facts.
  • DE-A 30 47 119 describes a method according to which errors which arise due to the absence of the first axis pulse at an axis detection point consisting of two rail contacts which are offset from one another on the track and which lead to an incorrect specification of the axis passage direction, can be detected and automatically corrected .
  • the axis detection point is used here, although its structure corresponds to a counting point in an axle counting device, not to count the axles but to control safety devices at level crossings.
  • speed measurements can be carried out with the aid of two rail contacts located one behind the other.
  • DE-A 15 30 389 describes a method for the automatic determination and deletion of axle counting errors in self-blocking systems in railways, in which a comparison of axle counting results of the individual block sections with counting results, which were determined in sections lying further ahead, takes place and sections in between are subsequently released provided that the counting results of the sections located apart are the same.
  • the invention is intended to create a device which provides the axle counting and the track vacancy detection and train locating functions based on the axle counting with the aid of those already present in an electronic signal box of the type mentioned above Positioning group computer enables and makes separate axle counting devices in the signal box unnecessary.
  • the invention is described in claim 1.
  • the section-oriented axle counting in the for each track section, the number of axles balance is set up in a separate axle counting device, for point-oriented axle counting, with passing on of the counting results along the route. This not only saves assemblies, it also makes it possible to correct counting errors by comparing counting results obtained at several successive counting points without any additional circuitry.
  • the figure shows a part of the track diagram of a railway system.
  • Axle counting points ZP1 ... zp5 are arranged between individual control elements, which are separated from one another by dashed lines - signal groups S, SG and Z, switch groups W1, W2, crossing group K -.
  • each control group as in the case here the signal groups S, Z and SG, also two control elements (link elements + signal or 2 signals) can be assigned, there is a microcomputer or a multi-computer system consisting of several microcomputers working in parallel.
  • Each metering point which, as indicated in the figure, is formed by two axis detectors offset from one another, is connected to the two control groups adjacent to it by signal lines.
  • axle counting double pulses (two different pulse forms for the two possible directions of passage) are passed on to the control groups via these signal lines.
  • the microcomputers of the actuating groups count the axle counting impulses as forward or backward impulses and pass the result together with an indication of origin, which indicates the point of delivery from which the axle counting impulses originate, to the next following actuating group.
  • This transfer takes place via the geographic data connections simulated along the course of the track, exclusively along an established route. In control groups that do not belong to the route, only the counting impulses of the directly assigned axle counting points are processed.
  • the number of axles obtained at the two points of delivery in the direction of travel are available in each control group of the route used and can be compared with each other. If there is no discrepancy between the number of axles, the section between the metering points is marked as clear. To correct any counting errors, it is not sufficient to pass on the counting results obtained at the axle counting points to the next control group; they are therefore passed on across several control groups to the route target group. If a discrepancy is found between the counting results obtained at two metering points, it can be checked by comparison with results from metering points further ahead whether this deviation is due to a counting error or whether it is due to a real occupation of the track section. The counting error can then be corrected without a security risk.
  • the forwarding is therefore against the direction of travel required so that a track vacancy detection of the previous track section is possible in the manner described above even if the train changes direction.
  • the axle counting pulses obtained there are counted and stored in the setting groups W1 and K and, after passing through the last axle, passed on from the crossing group K to the signal group SG and against the direction of travel from the switch group W1 to the signal group S.
  • the counting results are not only passed on to the next but one control group but to all other control groups in the route up to the target group, it is possible, for example, to compare the number of axles obtained at metering point ZP1 with that obtained at metering point ZP3 or ZP4. If the number of axles in these comparisons match, it can be assumed that a difference between the number of axles obtained at metering point ZP1 and the number of axles obtained at metering point ZP2 is due to a counting error, because axes of a train cannot be lost along a set route go and reappear in the next section.
  • the microcomputer of the target group saves the number of axles obtained at the two previous metering points and only passes them on to the next group of this route after the following route has been set.
  • the device according to the invention can also be used for speed measurement.
  • the lengths of the track sections in front of the associated metering points are stored in the control groups.
  • the control groups contain measuring circuits which record the time elapsed between two axis passes at successive metering points and additional time circuits which allow a specific axis (e.g. the 1st axis) of a train to be recognized, for example by eliminating axes which follow within a certain period of time of a previously registered axis.
  • both the time measurement circuits and the time circuits for identifying the 1st axis can be implemented by routines of the microcomputers located in the setting groups, the computer clock being used as the time standard.
  • the desired average speed speed of a train within a track section results from a division of the stored track section lengths by the control group computers by the time measured by the time measurement circuit and required by the train for the track section.
  • An axle counting pulse registered at the counting point ZP2 after a long pause in counting starts the time measurement, which e.g. consists in a count of the computer clock pulses.
  • the counting is stopped when an axis is determined in the metering point ZP3.
  • the number of computer clocks counted corresponds to the time required by the train for the distance limited by the metering points.
  • a division of the stored distance by this determined time period finally gives the average speed of the train on the track section delimited by the metering points ZP2 and ZP3.
