Definitions

  • the invention relates to a method for free and busy reporting of Track sections.
  • Each axle counter contains one metering point, the two rail contacts and an evaluation unit having.
  • Each axle counter monitors one assigned to it Track section.
  • the axle counter detects a passing car Rail vehicle, the track section is switched busy. Detects the in the direction of travel of the rail vehicle nearest axle counter the passing rail vehicle, the track section is free again connected.
  • Is an axle counter for monitoring two or more consecutive track sections used may interfere with this point of delivery, e.g. caused by cable fault, to Occupancy report of these track sections and in case of troubleshooting Simultaneous free registration of these track sections lead.
  • This Simultaneous free signals can lead to dangerous operating conditions in the Signaling logic (dissolution circuit) lead.
  • the object of the invention is to ensure the safety of the correct axle counting Rail vehicles increase.
  • an interference signal is generated when at least one rail contact is influenced against the expected direction of a passing rail vehicle and / or at least one free, adjacent track section.
  • One metering point has two rail contacts. Depending on the direction of the passing rail vehicle, first one rail contact and then the other rail contact will detect axles of the passing rail vehicle.
  • the invention combines the evaluation of the detected axes by the rail contacts with the expected direction of the passing rail vehicle, such as a train. If, for example, a train is expected to pass first the first and then the second rail contact, the first rail contact first detects an axis of the train and then the second rail contact after a correctly functioning metering point.
  • the first rail contact is no longer able to detect axles or forward the detected information due to a cable break
  • only the second rail contact will detect detected axles when the train passes.
  • the combination with the expected direction of the passing train shows that a fault has occurred.
  • Trigger for the detection by the second, but not by the first rail contact is a non-functioning first rail contact. This fault must be remedied. This happens, for example, by a fitter who exchanges the rail contact on site.
  • both track sections adjoining the rail contact are switched to occupied. As a result, faults are detected quickly.
  • At least one Rail contact with at least one free, adjacent one Track section generated an interference signal.
  • a metering point By means of a metering point, the Occupancy and activation of a track section in the direction of passing train determined.
  • a chained section is a first metering point provided for a first track section and a second Point of delivery for a subsequent to the first track section second track section.
  • the method according to the invention is characterized in particular by that after the fault has been corrected, initially only one track section becomes free again is switched. Thus, not several track sections are released simultaneously connected. And that is the track section in the direction of travel of expected turn first unlocked. For the activation of the upstream track section is a free message by the adjacent Point of delivery provided.
  • the evaluation unit has a Arithmetic unit, which is programmed in such a way, three different Generate initial states, namely free, occupied and disturbed. Of the Output state free is generated if no influence on the Rail contacts occurs. The initial state occupied is generated, if influencing the rail contacts in the order according to the expected direction of a passing Rail vehicle and / or at least one occupied, adjacent track section occurs. The initial state is disturbed generated when influencing at least one rail contact contrary to the expected direction of a passing Rail vehicle and / or at least one free, adjacent Track section occurs.
  • the metering point is characterized in particular by the fact that the Output state is generated freely, if previously the initial state occupied and from the direction of the passing Rail vehicle adjacent counting point receive a release signal becomes.
  • an arithmetic unit is for processing of signals from at least two points of delivery with two each Rail contacts provided.
  • the arithmetic unit is programmed in such a way generate three different output states for each counting point namely free, occupied and disturbed.
  • the initial state becomes free generated when no influence on the rail contacts occurs, the Initial state occupied, if an influence of the rail contacts in the order according to the expected direction of a passing rail vehicle and / or at least one occupied, adjacent track section occurs and the initial state disturbed when influencing at least one rail contact contrary to the expected direction of a passing Rail vehicle and / or at least one free, adjacent Track section occurs.
  • the arithmetic unit is for example as Microprocessor, digital signal processor or microcontroller executed.
  • the Programming is done for example by means of a special Software program in C ++ programming language or by means of at least two software program parts residing on one or more memory can be stored and access to the different processors can have.
  • it is centrally located, e.g. in one electronic interlocking and is designed so the evaluation and / or the generation of the states free, occupied and disturbed for to take over at least two points of delivery.
  • To determine a Condition is disturbed a comparison of the time sequence of the detection of Axes performed by two rail contacts of a metering point.
  • the timing of the detection - e.g. first first Rail contact and shortly thereafter second rail contact - expected - e.g. first before second rail contact due to the direction of travel of the expected, passing train -, so there is no disturbance.
  • Complies the timing of the detection is not the expected, so is one Fault before and the condition is disturbed is generated.
  • not only the time sequence of Detection of the axes but also monitors their number. Detects the first and the second rail contact the same number of axes no disturbance. Is the number different? there is a fault and the condition is disturbed is generated. This is done by software a comparison between the number of detected axes of both rail contacts carried out. This is done e.g. by using two counters. If the counts are correct, taking into account the time delay the detection match, there is no interference. A comparison is made e.g. under Consideration of the direction of travel after a certain period of time, which is advantageously selected depending on the speed of the passing train. If a train is traveling, e.g. with 200 km / h in the direction of the first Rail contact before second rail contact, so a comparison below Considering that axes e.g. not more than 40 meters apart, 0.72 seconds after the last detection by the second Rail contact done.
  • Each counting point has two rail contacts Sk1, Sk2 and an evaluation unit evaluation on.
  • the rail contacts Sk1, Sk2 are used to detect the axes of a passing rail vehicle, e.g. a train.
  • the evaluation evaluation units are mutually on at least one Data line connected for the purpose of exchanging information.
  • To this Information includes e.g. the condition of a track section, e.g. free, occupied, disturbed.
  • Each counting point Zp1, Zp2, Zp3 is part of an axle counter and is further Advantageously via at least one data line with a electronic interlocking and the adjacent metering points connected.
  • Each evaluation unit evaluation has an arithmetic unit, which, e.g. when Microprocessor, signal processor or microcontroller with special Software is designed.
  • Each evaluation unit evaluation is carried out by the electronic interlocking informed about the direction of the expected train. In addition to Direction is the exact time or a period transmitted during which the train is expected at the respective point of delivery.
  • the Evaluation units as in the embodiment decentralized at the Locating the metering points or centrally, advantageously summarized in an evaluation be arranged in the electronic interlocking.
  • the rail contacts Sk1, Sk2 of a metering point report the detected Axes of a passing train of the associated evaluation unit Evaluation. This compares the temporal sequence of the detections with the expected direction of travel of the pre-traveling train and generated at lack of agreement a fault message. This will be the transmitted electronic interlocking.
  • the disturbed condition can only by an operator can be left controlled.
