Definitions
- the invention is in the field of shunting technology and relates a method for forming a replacement value for a running characteristic of wagons on a shunting system, based on at least one archived Long-term mean value for the property determining the run Evaluation of measured values obtained from current wagon runs a tracked long-term average is generated.
- Original train sets are used on shunting or drainage systems for example, according to a disassembly list and resolved by The specified entry of individual wagons or groups of wagons in different direction tracks to new car groups or Trains put together.
- the mastery of the running behavior of the free running Carriage and the dome-ready running in with permissible Acceleration speed is of particular importance.
- the marshalling system must have the characteristics that determine the running in each case the running wagon or the wagon group if possible be forecast realistically.
- the object of the invention is therefore to create a Method for forming a replacement value for a run-determining Property of wagons on a marshalling yard, the automatically an undesired long-term influence for a short time due to changed environmental conditions Avoid long-term averages.
- This task is carried out in a method of the aforementioned Art solved according to the invention in that the replacement value proportionately from the archived long-term mean and the updated one Long-term mean is formed and that the proportion of the updated long-term mean with increasing age the last tracking is automatically dimensioned smaller.
- An essential one The advantage of the method according to the invention is that that as a result of sudden, briefly changed environmental conditions significantly from the archived long-term mean deviating measured values due to the function of the measured value age (Update time) increasingly smaller Weighting only a temporary large deviation of the cause updated from the archived long-term mean. Because the replacement value is at least partially from the archived Long-term mean is formed even for a short time extremely faulty measured values a reliable feedback to "normal values".
- the method according to the invention avoids self-regulating that one due to short-term Changes in environmental conditions necessary tracking of Long-term mean an unwanted at a later date unrealistic formation of the replacement value for consequences may have. This is particularly so when resuming the Operating advantageous after a long break during of the original environmental conditions significantly might have changed.
- the updated long-term mean can basically be known Are generated in such a way that the current measured values in relation to the number of averages Total number in the archived or measured earlier Enter the measured values of the long-term average that has already been updated. However, those represented by the measured values are found Changes only a relatively slow rainfall in the long-term mean. Therefore can be preferred be provided that the current measured values with a stronger (than their ratio to the total number corresponding) weighting in the updated long-term mean come in. This can be done, for example, by that the deviation of a number of current measured values determined from the updated long-term mean and as Correction value the long-term mean value for tracking is opened.
- the determination of the rolling resistance is known per se and for example in DE-OS 22 46 306 and DE-A1 42 14 541 described.
- Running characteristics are important of wagons significantly dependent on the temperature. It is therefore for example from DE-A1 42 14 541 known for a property that determines the running (e.g. for the Rolling resistance of a wagon) archived long-term mean values or to determine start values depending on the temperature.
- a property that determines the running (e.g. for the Rolling resistance of a wagon) archived long-term mean values or to determine start values depending on the temperature.
- a particularly practical ratio of the shares of archived and tracked long-term mean takes place at the Formation of a replacement value according to the method according to the invention prefers its precipitation in that the portion of the updated long-term mean during a first Duration constant and during a subsequent second Time is reduced to zero, whereby the Share of the archived long-term mean value accordingly is increasingly dimensioned.
- the proportion of long-term mean values is preferred provided according to the current temperature.
- a particularly preferred application of the method according to the invention is the updating of substitute values for the rolling resistance force (FACHS) of a rolling axis.
- the rolling resistance is largely independent of the load and therefore characteristic of the car.
- a maneuvering system 1 operated at the temperature T1 comprises a drain mountain 2 and a drain region 3 directed downwards, which branches into direction tracks RG1, RG2, RG1 and RG4.
- a train or carriage group 10 is pushed uphill by a push-off locomotive 11 in such a way that a large number of individual carriages Wi (carriages W1, W2, W17, W18, W19 and W20 are explicitly shown) or carriage groups are successively released.
- the carriage W1 is in free running in the valley area 3 and passes through a detection zone EKZ in which, for example, the axle configuration (number, arrangement, distribution of the axles) is determined and the running times of the carriage axles are measured in a measuring section.
- Directional track brakes RB1 to RB4 are applied according to the measured values MWi controlled to enter with the highest possible track filling to achieve dome-ready running.
- the measured values MWi assigned to the running carriage Wi become 2 in a FIFO memory SP with 20 memory cells written in serial, so that the last 20 measured values MW1 to MW20 are present in the memory SP.
- archived long-term mean values ALM1 to ALM3 are used. These are in advance (OFF-Line) for different temperatures T1, T2, T3 determined and saved individually for each class been.
- the archived Long-term mean ALM1 used (arrow PO), because on the Shunting system temperature T1 ( Figure 1) prevails.
- the Long-term mean values ALM1 to ALM3 are used to create substitute values EW and are now taking into account the current Processes and their measured values MWi tracked.
- each measured value MWi is marked with a Provide timestamp of the time ti of the measured value recording indicates.
- each deviation ⁇ 1 to ⁇ 20 (generally ⁇ i) determined in this way can be checked in a first comparison VGL1 to determine whether it lies within a tolerance range. For this purpose, the amount of the deviation ⁇ i with respect to a first threshold value S1 is determined.
- the respective deviation ⁇ i is taken into account in a subsequent averaging MWB.
- the threshold value S1 the threshold value for the amount of the deviation ⁇ 17.
- the mean deviation value AWM can track the previous one Long-term mean NLM1 with a weighting factor ⁇ be opened, the short-term influence of the measured value deviations makes adjustable.
- the immediate Activation of the mean deviation value AWM is erratic and immediate tracking (adaptation) of the tracked Long-term average NLM1 reached.
- the oldest Measured value MW1 read out from the memory SP and as by the arrow indicated with P2 indicated for tracking the Long-term mean NLM1 can be added.
- the measured value MW1 would go according to its weighting, which results from the Total number of values considered for the classic Long-term averaging results in the updated long-term mean on.
- the measured value MW1, MW2 etc. can preferably also remain entirely without influence if based on its time stamp t1, t2 the exceeding of a maximum permitted age from Z. B. 12 hours is recognized.
- the proportion AN of the updated long-term mean value NLM1 is measured according to FIG. 3 in a first period of 3 hours and is 60%. Accordingly, the substitute value EW is formed 60% from the updated long-term average NLM1 and 40% from the archived long-term average ALM1.
- the proportion of AN is therefore measured at 40%.
- the second substitute value EW ' is therefore only 40% determined by the updated long-term mean value NLM1 and 60% by the archived long-term mean value ALM1.
