- the procedural object is achieved in that in a method of the type mentioned by the sensor at and additionally before and / or after a rollover of the infrastructure component by a rail vehicle data is collected and segmented, wherein from the detected and segmented data, a state of the infrastructure component is determined.
- An advantage achieved with the invention is to be seen in particular in that, by segmenting the data, a state of a route component can be continuously, automatically and in-situ monitored or determined. It can be monitored, for example, moving points, rigid Weichenherzen, rails and / or sleepers of a railway line. Data is preferred in each case
- a response of the infrastructure component to a current operation is used to make statements about a state of the same, for example, a time-resolved development of an elongation at a certain position.
- a load of the corresponding infrastructure component before, during and / or after a rolling over or crossing of a rail vehicle is measured or recorded at a measuring point for all rail vehicles.

- a type of load on the infrastructure component can be characterized.
- a state of a track component is monitored by a single sensor, in particular by a strain sensor, which z. B. may be formed as strain gauges or optical strain gauge.
- a state of a infrastructure component such as a railroad switch is determined by a method according to the invention, but optionally also a state of a wheel of a rail vehicle. For example, hollow or out-of-round wheels are detected. This is especially true for one
- Movement component shifted This can be detected by appropriate comparison algorithms. Further, a transition between a rail and a
- Track switch formed discontinuous, so that in a roll over the same both the rail switches and wheels of the rail vehicle are loaded.

Furthermore, for example, a state of a switch heart of a rail switch is predicted with predetermined algorithms. In addition, envelopes are used to isolate individual measurements for further analysis. It will also be detected by the envelope long-term deviations of the same, which indicate continuing changes. A prerequisite for the evaluation of the data with envelopes is the segmentation of the same as well as the automated determination of a train speed from sensor data.

In addition, it distinguishes in particular random noise or disturbances caused by natural sources from an approaching rail vehicle. Noise caused by conventional sources usually has a Gaussian distribution. Another statistical distribution of data suggests other causes, such as a defective rail vehicle itself, a misshaped wheel, a lowered rail switch or other deviations. In a first step, therefore, a statistical distribution of data is determined and checked whether the data is a
- Gaussian distribution or statistically distributed differently.
- a cause of the noise is determined from this. If there is no Gaussian distribution, the noise is caused by an irregularity. It has proved to be favorable to automatically check those data which are obtained from a load of the infrastructure component immediately before rolling over the same by a rail vehicle by a so-called Kolmogorov-Smirnov test.

- one or more sensors and in each case a signal processing system are arranged on a plurality of track components.

- Rail switch arranged sensor to separate.
- the temporal segmentation may be used additionally or alternatively to separate overflow signals of a locomotive and wagons as well as for the separate analysis of individual axes.
- a monitoring of the statistics of the strain signals before and / or after an actual railroad overflow makes it possible to distinguish between rail vehicles without faulty running behavior without restrictions. Consequently, such information can be provided to a railway operator.
