Definitions
- the present invention relates to a method and a device for determining at least one characteristic characteristic of an electrical resistance between rails of a railroad track in the presence of an axle shunt.
- track circuits are used to check the occupancy of track sections, points and block sections by rail vehicles.
- a so-called axle shunt is formed by driving a track circuit via a wheelset or several sets of wheels of the respective vehicle, which leads to the occupancy report of the track free detection section in question.
- the electrical resistance of the wheel ⁇ rates traversed by the section of track rail vehicles is small enough to cause sufficient for a safe, reliable Be ⁇ legungserkennung Achsneben gleich.
- the present invention has for its object to provide a method and an apparatus for determining at least one for a electrical resistance between rails of a railway track in the presence of a AchseinbenBankes cha ⁇ characteristic figure, which can be realized with little effort and at the same time are particularly flexible.
- This object is achieved by a method for determining at least one for an electrical resistance between rails of a railway track in the presence of an axle shunt characteristic characteristic using a measuring points free of insulation joints, in the region of the measuring point an electrical alternating voltage with a frequency greater than 1 kHz is fed into the rails, while passing a rail vehicle at the measuring point at least one of the electrical resistance between the rails of the railway track dependent Meßgrö ⁇ ße is detected and based on the at least one detected measured the at least one of the electrical resistance between the rails of the railway track characteristic characteristic variable is determined in the presence of an axle shunt.
- this is thus initially characterized by the fact that a measuring point free of insulating joints is used.
- a measuring point free of insulating joints is used.
- This is advantageous because a separation of the rail or the rails by insulating joints in practice is associated with considerable disadvantages. So it would be an electric Iso ⁇ -regulation of the respective measuring point from the environment as customarily require to separate at least one of the rails with two insulated rail joints. The necessary for this
- the at least one dependent on the electrical resistance between the rails of the railway track measured variables ⁇ SSE is detected during a pass-by.
- the at least one detected measured variable serves as the basis for a subsequent assessment of the conductivity ⁇ ability of at least one wheelset of the rail vehicle in question.
- the respective railway vehicle having bogies, in which several wheel sets are arranged spatially closely hinterei ⁇ Nander, in this case also a common Be ⁇ trachtung or evaluation of the wheel sets of the Drehge ⁇ site can take place.
- ⁇ least one characteristic of the electrical resistance between the rails of the railway track in the presence of a Achsneben- circuit parameter is determined on the basis of at least a detected measurand.
- ⁇ ness on the concrete realization can be in at least one of the electrical resistance between the rails of the railway track in the presence Achsneseit gleiches characteristic characteristic beispielswei ⁇ se to a resistance value, a voltage value, a
- the entspre ⁇ sponding electrical resistance is made here of a specific to the respective wheel Radsatzwiderstand and contact resistance with respect to the transition between wheelset and rails together.
- the inventive method makes it possible to determine the charac ⁇ teristic parameter specific to the wheel.
- the characteristic parameter for egg ⁇ nen, several or all wheelsets of each rail vehicle can be determined in each case specifically for the individual wheelset.
- the inventive method has the advantage that it allows a reliable determination of the at least one electrical resistance between the rails of the railway track in the presence of a AchsnebenInstitutes charac ⁇ rule parameter. Because of this, which uses a measuring point free from insulation joints in the context of the method is, the inventive method can be realized with little effort. In addition, there is advantageously the possibility of setting up a corresponding measuring point flexibly at a respective desired location without the need for structural changes to the rails or other components of the trackside infrastructure.
- the at least one electrical resistance between the rails of the railway track in the presence of Achsneben gleiches charac ⁇ specific parameter is based on at least one maximum value and / or at least a minimum value in the temporal course of the at least one detected Measured variable determined.
- This is ⁇ geous because corresponding extreme values at least one measured quantity recognized as characteristic parameter for the electrical resistance between the rails of the railway track in case of a Achsneben gleiches are particularly well suited overall of.
- the at least one charac teristic ⁇ characteristic is thus formed by at least one maximum value and / or at least a minimum value in the temporal course of the at least immediately formed a detected measurement variable or derived from a corresponding extreme value.
- the at least one characteristic is thus formed by at least one maximum value and / or at least a minimum value in the temporal course of the at least immediately formed a detected measurement variable or derived from a corresponding extreme value.
- Characteristic are determined from the at least one detected measured variable.
- the inventive method can also be configured such that during the passage of the rail ⁇ vehicle at the measuring point, the at least one of the elekt ⁇ cal resistance between the rails of the railway track dependent variable in the form of an electric current, an electrical voltage and / or a electrical power is detected.
- This embodiment of the method according to the invention is advantageous in that the aforementioned measured variables are those which are simple and are dependent on the electrical resistance between the rails of the railway track.
- the measured quantities mentioned here are tapped between the rails of the railway track at or near the point at which the electrical alternating voltage is fed into the rails.
- the inventive method can also be configured such that the rails are electrically connected in the region of the measuring point in the absence of rail vehicles by means of a Refe ⁇ resistance, the electrical AC voltage with the frequency of greater than 1 kHz is fed into the rails, at least a dependent of the elekt ⁇ step resistance between the rails of the railway track measurand is detected, and on the basis of at least ei ⁇ NEN detected measurement variable, a reference value for the at least one characteristic variable is determined for the electrical resistance between the rails of the railway track in the presence of AchsnebenInstitutes.
- This preferred embodiment of the method according to the invention is advantageous in that the reference value determined for the at least one electrical resistance between the rails of the railway track in the presence of AchsnebenInstitutes charac ⁇ teristic characteristic of a simple comparison with while in the passage of a rail vehicle at the measuring point
