  • the present invention has for its object to provide a simple and at the same time versatile method for determining the coupling state of a railway coupling with vertically movable coupling elements, in particular a screw coupling.
  • This object is achieved by a method for determining the coupling state of a railway coupling with vertically movable coupling elements, in particular a screw coupling, wherein at least one provided on or in at least one of the coupling elements of the railway coupling inclination sensor at least one vertical orientation of the coupling element indicative measured value is detected and from the at least one measured value of the coupling state of the railway coupling is determined.
  • the method according to the invention is advantageous in that the vertical orientation of the relevant coupling element and thus also the coupling state of the railway coupling can be determined by the at least one inclination sensor provided on or in at least one of the vertically movable coupling elements of the railway coupling.
  • the inclination sensor is advantageously attached to one of the coupling elements such that the different coupling states of the railway coupling can be distinguished reliably.
  • a railway coupling in the form of a screw coupling of the inclination sensor is attached to the bracket or the tab of the screw coupling, since in these cases a particularly clear and thus distinguishable angle change in the respective states can be measured.

  • the inclination sensor determines cyclically, at variable time intervals or continuously, the position of the railway coupling or of the vertically movable coupling element to which the inclination sensor is attached.
  • an inclination sensor is generally understood to be a sensor device which is suitable for determining a measured value which directly or indirectly indicates the vertical orientation of the coupling element.
  • an inclination sensor can determine the vertical orientation according to any measuring principle known per se.
  • Corresponding inclination sensors are, for example, in the form of static accelerations acting on the measurement, that is to say in particular of gravitational acceleration or gravitational acceleration, trained acceleration sensors known from the prior art and comparatively inexpensive available on the market.
  • the inventive method is configured such that the at least one measured value is transmitted to an evaluation device.
  • an evaluation device can be arranged at different locations.
  • freight wagons are increasingly equipped with telematic devices, which are also referred to as telematics boxes.
  • Corresponding telematic devices allow, for example, a route determination and monitoring of the respective vehicle. Since telematics devices usually have at least one control device in the form of a processor, for example such a control device can be used as an evaluation device in the context of the described preferred development of the method according to the invention.
  • a component of the telematics device as an evaluation device, it is also conceivable that by means of the telematics device a transmission of the at least one measured value to a central evaluation device, for example in a control device of a drainage system may be arranged to transmit.
  • the evaluation device for example, also be firmly mounted on or next to a track. This is useful, for example, if in each case at a certain location, a determination of the coupling state of usually moving to the evaluation device passing railway vehicles, ie in particular of freight cars, is desired.
  • the evaluation device Regardless of where the evaluation device is arranged, together with the at least one measured value, preferably, a identifier identifying the respective railway coupling and / or the respective goods wagon is transmitted and processed. This makes it possible to ensure that the respective at least one measured value can be clearly assigned to a railway coupling or to a freight wagon.

  • it can be determined by means of the inclination sensor that the railway coupling or the vertically movable coupling element, on or in which the inclination sensor is provided, during the journey or at the wrong time, i. For example, outside of a train station and outside of scheduled transitions, it leaves the coupled state and, instead, hangs down loosely when disengaged. This is thus a clear indicator of an unwanted train separation, so that a corresponding alarm, e.g. should be triggered by a signaling to the train driver and / or to a control center.
  • the inventive method can be advantageously used to determine separation points between the running freight cars. This can be done, for example, in such a way that an evaluation device, which can be mounted, for example, next to the track, which evaluates the measured values received by the inclination sensors of the passing freight cars. In this case, for example, it can be checked whether the couplings are in an expected state at a planned separation point. In the case of a screw coupling, this means that the relevant screw coupling is disengaged hanging loosely down or hooked to its own coupling holder.
