A transmitter device for a sensor device detects a magnetic field change caused by an object approaching or moving past the sensor device, in particular by a wheel of a rail vehicle. The transmitter device has at least two alternating-current-fed transmitter oscillating circuits. In order to implement error disclosure of the sensor device in a particularly simple manner, the at least two transmitter oscillating circuits are formed in such a way that the resonance frequencies thereof are different from each other. A sensor device and a method for detecting a magnetic field change are also provided.

An axle-counting method for railbound vehicles includes the following method steps: coupling light into at least one sensor fiber, wherein the sensor fiber includes at least one fiber Bragg grating mounted on a rail, wherein each fiber Bragg grating has a reflection spectrum having a reflection peak which is at a Bragg wavelength and has a full width at half maximum; generating a difference signal from two shear stress signals through detection and filtering the temporal intensity course of the light power reflected by two Fiber Bragg gratings which are arranged at a separation from one another; and generating a wheel signal if the difference signal exceeds a predetermined shear stress difference limiting value.

A preceding train identification method based on an object controller, includes: carrying out communication interaction, by a vehicle on board controller of a train, with the OC to acquire the ID information of all running trains within the jurisdiction of the OC, before the train enters the jurisdiction of the object controller OC; communicating, by the vehicle on board controller, with the train corresponding to each piece of ID information according to the ID information of all running trains to acquire the position information of the train corresponding to each piece of ID information; and sorting, by the vehicle on board controller, the position information of the trains corresponding to all ID information in an axle counter sorting manner to identify the ID information of an adjacent preceding train of a present train. A vehicle on board controller and a train are also provided. By adopting the method of the present disclosure, preceding train information necessary for a present train can be screened out from online train information quickly and effectively.

A method and apparatus to detect breaks in tracks and/or detect the presence of a vehicle, such as a train, in a monitored section of the track or rail. Embodiments of the present invention measure the change in track inductance associated with a track or rail break. Electrical shunts are connected between the rails at spaced-apart intervals (for example a shunt can be placed every mile). At least two different frequencies of alternating current are generated and fed into the segments of rail (for example at or near a mid-point between the shunts). If a rail break occurs, the total inductance of the rail at that segment will change. Using two or more frequencies allows a rail break to be differentiated from environmental rail-to-rail and rail-to-earth leakage.

A method for data transmission inside a rail-bound traffic system has of a plurality of field elements, in which the data transmission takes place via a flexible wireless transmission path between a sender field element and a control unit along available field elements. A data transmission system is for application of the method and a rail-bound traffic system having such a data transmission system. Furthermore, there is use of communication units on field elements of a rail-bound traffic system to form the data transmission system.

A method for operating an axle counter system for monitoring the occupation status of a track section being limited by counting positions which have at least one detection point and at least one counting position a set of redundant detection points, includes the steps of: (a) incrementing or decrementing axle counter values in dependence of the moving direction of a passing axle; (b) transmitting the axle counter value to an axle counter evaluator; (c) determining the number of remaining axles within the track section; and (d) outputting a track occupation status. Prior to step (c) for each counting position exactly one detection point is selected for further processing independent of the selection at any other counting position. In step (c) the counter values of the selected detection points are used for determining the number of remaining axles and the counter values of the non-selected redundant detection points are ignored.

A method for detecting sealing stickers on a packaging box includes placing a first packaging box onto a conveyor belt of a conveyor belt system at an inspection zone, the first packaging box having a first sealing sticker thereon that at least partially seals the first packaging box closed; and activating a first optical sensor to detect whether the first sealing sticker is located on a first side of the first packaging box while the packaging box is in the inspection zone.

A system and method for virtual block stick circuits is presented. The present disclosure implements specialized algorithms adapted to determine the true status of a virtual block based on multiple inputs from different perspectives. In one embodiment, the system can use the far house perspective of that virtual track segment and the PTC hazard for the near virtual track segment directly adjacent to the near house uses the near house perspective of that virtual track segment. For the middle virtual track segments, the near house perspectives of the middle virtual track segments are held TRUE if they are already TRUE when the train first enters the block, using stick circuits for the near house perspective of the middle track circuits. The vital application can then indicate the true state of the virtual track segment as occupied (FALSE), to protect the train from trains that follow.
