Definitions

  • rail vehicles are sorted using the force acting on the rail vehicles gravity from a mountain track in different direction tracks.
  • the rail vehicles are cars or groups of cars, which are usually referred to as processes.
  • the most accurate prognosis of the running behavior of the processes is desirable when operating a drain system. This applies, on the one hand, with regard to avoiding in-flight operations during their course in the direction of the directional tracks, since these could lead to accidents or damage to the processes or the transported goods.
  • the most accurate prediction of the running behavior of the individual processes also allows a maximization of the capacity of the drainage system, i. maximizing the number of cars that can be sorted by the drainage system over a certain period of time.
  • An important influencing factor in the control of a drainage system is the rolling resistance of the respective sequence, since this is required, for example, for the control of rail brakes provided for influencing the speed of the sequences.
  • the quality of maneuvering for example, with regard to maintaining a given target speed or the accuracy of a running target braking, can not be guaranteed in many cases to the extent that would be desirable.
  • the present invention has for its object to provide a method for operating a drainage system of the rail-bound traffic, which allows an improved performance of the drainage system by an improved forecast of the rolling resistance of the processes.
  • At least one rolling resistance information is determined for operations in the form of expiring cars or groups of cars in at least one track section of the drainage system and taking into account the determined rolling resistance information and at least one is predicted for the respective track section specific reference rolling resistance information of the rolling resistance of the respective sequence in at least one subsequent track section of the drainage system.
  • At least one rolling resistance information is thus determined in at least one track section of the drainage system. It depends on the specific characteristics of the respective drainage system and optionally also on properties of the respective process, ie for example its length, whether the determination of the at least one rolling resistance information takes place only in one or more track sections of the drainage system.
  • the rolling resistance information is a related to the rolling resistance of the respective sequence size, which can be given on the one hand by the rolling resistance itself and on the other hand by another size, which indirectly or directly allows a statement about the rolling resistance of the respective process.
  • the rolling resistance of the respective sequence in at least one subsequent track section is predicted taking into account the determined rolling resistance information and at least one reference rolling resistance information specific to the respective track section. This means that a prognosis is made for the rolling resistance of the respective sequence in the at least one subsequent track section based on the rolling resistance information determined in the at least one preceding track section and the at least one reference rolling resistance information specific to the respective preceding track section.
  • the method according to the invention is advantageous since, by including the reference rolling resistance information, an improved prediction or prognosis of the rolling resistance of the respective sequence in the at least one subsequent track section of the drainage system is made possible.
  • conclusions and measured values gained in particular from previous processes can be included in the reference rolling resistance information.
  • the achieved improvement in the forecast of the rolling resistance of the processes the performance, ie in particular the capacity and / or the reliability of the drain system increases.
  • the predicted rolling resistance is used for the control of at least one track brake of the drainage system.
  • This is advantageous since the improved prognosis of the rolling resistance of the respective sequence in the at least one subsequent track section of the discharge system can thus be used for improving the speed influencing of the sequences taking place by means of the at least one track brake.
  • This ultimately results in predetermined target values for the speed of the operations at certain points of the effluent system, i. For example, in the area of a conveyor system, or in the case of a running target braking also aspired running goals of the processes can be met with greater accuracy and reliability.
  • the method according to the invention is configured such that the rolling resistance is predicted taking into account the determined rolling resistance information and at least one reference rolling resistance information specific to the respective track section and to the route of the respective sequence.
  • the accuracy of the prognosis can be further improved by the fact that the reference rolling resistance information is specific not only for the respective track section, but also for the respective route of the procedure.
  • the rolling resistances of processes are regularly determined in such a way that starting from several speed measurements or measurements of rollover times of axes of the processes all known effects and boundary conditions, such as track inclinations, track resistance, wind direction, wind speed and temperature, are taken into account and the remaining resistance is determined or established as a rolling resistance of the respective sequence.
  • the inventive method can also be so pronounced that the rolling resistance of the respective sequence in the at least one subsequent track section is predicted by performing a comparison of the determined rolling resistance information and the at least one reference rolling resistance information.
  • a comparison of the determined rolling resistance information with the at least one reference rolling resistance information makes it possible to make a statement about the deviation of the determined rolling resistance information from the at least one reference rolling resistance information.
  • the rolling resistance is set to a substitute value within the scope of the prognosis, if the comparison determines a deviation of the determined at least one rolling resistance information from the at least one reference rolling resistance information in terms of amount exceeding a first threshold ,
  • the determined rolling resistance information is based on the comparison with the reference rolling resistance information as "outliers" in that the deviation between the two variables exceeds a first threshold in absolute value, the determined Rolling resistance information discarded and the rolling resistance can be set as part of the forecast to a replacement value.
  • the respective substitute value is preferably the value resulting from the reference rolling resistance information minus or in addition the first threshold value.
  • the method according to the invention can also run such that the at least one reference rolling resistance information specific to the respective track section takes into account the at least one rolling resistance information determined in the respective track section of the rolling resistance predicted for the respective course in the at least one subsequent track section and one in the at least one subsequent track section when passing through the same determined rolling resistance is adjusted.
  • This is advantageous in that in the course of the procedure on the basis of a comparison between the predicted for a subsequent track section rolling resistance and the subsequently determined or reported actual rolling resistance of the process in the subsequent track section an automatic Adaptation or optimization of the process is achieved.
  • the adaptation or adaptation of the at least one reference rolling resistance information specific to the respective track section can, for example, take place in such a way that a multiplicity of sequences is taken into account by averaging the determined rolling resistance information.
  • a multiplicity of sequences is taken into account by averaging the determined rolling resistance information.
  • these may be long-term effects, such as wear-related changes.
  • By a pronounced overweighting of last expired processes, such as by means of the so-called exponential forgetting method it is advantageously also possible to take account of comparatively short-term changes or influences. This may be, for example, weather-related changes or environmental influences, since, for example, rain, snow or ice have significant effects on the rolling resistance of the processes.
  • the method according to the invention is so pronounced that the adaptation of the at least one reference rolling resistance information is omitted, provided that the deviation between the determined for the respective track section at least one rolling resistance information and the at least one reference rolling resistance information in terms of amount exceeds a second threshold.
  • This embodiment offers the advantage that adaptation or adaptation of the at least one reference rolling resistance information takes place only with reference to those processes for which the determined at least one rolling resistance information lies within a predetermined scattering range around the reference rolling resistance information. This ensures that a falsification of the reference rolling resistance information, for example due to a single measurement error or due to a sequence with a technical defect, is omitted.
  • the rolling resistance information within the scope of the method according to the invention may advantageously be of any desired size which directly or indirectly permits a statement about the rolling resistance of the respective sequence.
  • the method according to the invention can also be developed in such a way that the at least one rolling resistance information is determined in the form of a resistance force related to the average axle weight of the respective sequence.
  • the rolling resistance of a sequence depends in particular on the mass or the weight of the respective sequence. If a drag force related to the average axle weight of the respective sequence is determined as rolling resistance information, this effect can advantageously be at least largely taken into account or corrected.
  • the rolling resistance of the respective sequence in the at least one subsequent track section is predicted, taking into account at least one reference rolling resistance information independent of the type of the respective procedure.
  • the reference rolling resistance information is specific to the type or class of the respective process.
  • a prognosis taking into account or using a reference rolling resistance information independent of the type of the respective sequence offers the advantage that the method sequence as such is simplified. Furthermore, this ensures that sufficiently accurate reference rolling resistance information is also available for types of processes which occur comparatively rarely, which advantageously also take into account comparatively short-term changes in the operating conditions.
  • the inventive method is further pronounced such that the at least one rolling resistance information is determined exclusively for processes in the free, unbraked run.
  • the at least one rolling resistance information is determined exclusively for processes in the free, unbraked run.
  • the invention further comprises a control device for a drainage system of the rail-bound traffic.
