A decision module of the respective channel is bi-directionally connected to the measurement and feeding module. The measurement and feeding module of each channel includes a temperature measurement module and/or a module for measurement of mechanical vibration, that is/are connected with an input/inputs of a decision module of the channel. The decision modules are connected via a bidirectional digital interface. The decision module of one channel is connected via a bidirectional digital interface with a data transmission module for communication with a supervisory system via a data transmission line.

A method for determining the speed of a rail-bound vehicle, includes the following method steps: detection of a reference element, wherein the first detection device generates a first detection signal when the reference element passes the first detection device; detection of the reference element, wherein the second detection device generates a second detection signal when the reference element passes the second detection device; conversion of the detection signals into digital detection pulses; determining the time difference between the two detection pulses; wherein an XOR signal is generated in an XOR gate by linking the first and the second detection pulse using an XOR logic; and the duration of the XOR signal is determined; and wherein the time difference between the two detection pulses is determined by halving the duration of the XOR signal. The speed can be measured with higher accuracy when using an existing infrastructure without additional assembly work.

This application relates to methods and apparatus for distributed fibre optic sensing and especially to the processing of signals derived from such sensing techniques to characterise events of interest. The application describes a method of distributed fibre optic sensing, comprising; performing distributed fibre optic sensing so as to generate at least one set of measurement signals from each of a plurality of sensing channels of an optical fibre (101) in response to at least one event of interest. For each set of measurement signals, processing the measurement signals from different sensing channels according to an association metric to determine whether any sensing channels are associated with one another and form at least one association matrix indicative of the sensing channels that are associated with one another. The method further comprising performing distributed fibre optic sensing to acquire a further set of measurement signals from said sensing channels in response to a further event of interest and processing said further set of measurement signals based on said at least one association matrix to characterise said further event of interest.

A method and device for ascertaining movement authority for track-bound vehicles allow interference with a driving operation resulting in special operational situations or disturbances to be kept as low as possible. The position of the vehicle is determined and used to check whether the vehicle is located completely in an axle-counting section of an axle-counting system. The number of axles of the vehicle is compared with the number of axles located in the relevant section according to the system. If the vehicle is located completely in the relevant section and the number of axles of the vehicle matches the number of axles located in the section according to the system, a movement authority is ascertained for the vehicle. The part of the relevant section in front of the vehicle in the driving direction is assumed to be free of other vehicles when ascertaining the movement authority.

An evaluation unit 10 for a sensor arrangement for railway monitoring is described, the evaluation unit 10 comprising a connection to a position sensor 11 and a connection to a tracking sensor 12. The position sensor 11 is capable of detecting rail vehicles 19 passing over the position of the position sensor 11 on a railway track 14 and provides a position output signal 15. The tracking sensor 12 comprises a fibre optic sensor 16, which is capable of detecting the position of noise along the railway track 14 and the tracking sensor 12 provides a tracking output signal 18. The evaluation unit 10 provides an output signal 13 that depends on the position output signal 15 and the tracking output signal 18. Further, a sensor arrangement for railway monitoring and a method for evaluation of railway monitoring signals are described.

A strain gauge arrangement for an axle counter has a strain sensor element, a carrier and a railway line structure that is to be monitored. At least one part of the carrier is maintained in an elastically deformed state by the structure when the carrier is secured to the structure. The carrier is formed from a first carrier piece and a second carrier piece, which lie opposite one another at a distance from one another. The strain sensor element has one first fixing point fixed to the first carrier piece, and one second fixing point fixed to the second carrier piece, and a middle section mounted between the fixing points which are not fixed to the first or second carrier piece. The strain gauge arrangement is simple to handle and a drop can be reliably detected and a strain state of the strain sensor element can be predetermined more easily.

A method operates a track-bound traffic system which in a particularly efficient manner and at the same time with a comparably low degree of complexity allows the position of at least one vehicle end of a track-bound vehicle to be ascertained. For this purpose, the method is carried out such that a track-side device transmits first information which directly or indirectly characterizes the location of the track-side device and second information which directly or indirectly characterizes the travel direction of a track-bound vehicle. The first and second information is received by the track-bound vehicle at the location of the track-side device; and a position of at least one vehicle end of the track-bound vehicle is ascertained by the track-bound vehicle on the basis of the received first and second information.
