METHOD, VEHICLE DEVICE AND CONTROLLER FOR OPERATING A TRACK-BOUND TRAFFIC SYSTEM
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.
METHOD AND SYSTEM FOR HEALTH ASSESSMENT OF A TRACK CIRCUIT AND/OR OF A TRACK SECTION
A method and system for health assessment of a track circuit and/or of a track section, the track circuit being configured for detecting the presence of a vehicle on the track section between a transmitting end and a receiving end of the track circuit. The method, implemented by an electronic device, comprises obtaining, from a sensor device placed near the receiving end, samples of an electrical parameter of an electric signal transmitted between the transmitting end and the receiving end of the track section, forming a temporal series of received samples, applying an automatic clustering algorithm to separate the received samples in a predetermined number of clusters, selecting one of the clusters and determining, for the selected cluster, a first peak value of the received samples classified within the selected cluster, and calculating a track circuit health indicator depending on the first peak value determined for the selected cluster.
Method, controller and system for determining the location of a train on a track or of a broken rail of a track
The present invention relates to a method for determining the location of a train on a track or of a broken rail of a track, the track including a first section having a first end and a second end, the method including: injecting a current into the track at one end of the first end and second end; detecting the amplitude of the injected current at the same end at which the current was injected; and determining, based on the detected amplitude, the location of the train on the track or of the broken rail of the track.

A train detection system for a railway track section placed on a track bed, the track section having two rails, the train detection system comprising at least one cable, the cable being placed across the two rails, a transmitter connected to the cable and configured to emit an emitted signal into the at least one cable, a receiver connected to the cable and configured to receive a received signal related to the emitted signal having passed through the cable, and capable of determining, according to the received signal, between an unoccupied state where no railway vehicle is present on the track section, and an occupied state where the track section is occupied by a railway vehicle. The cable is buried under the track bed.
TRAFFIC CONTROL SYSTEM AND METHOD FOR PROVIDING A PREEMPTION SIGNAL
A traffic control system (100) includes a railroad crossing control system (10) with a constant warning time device (40), a wheel sensing system (120) with a sensor (122) connected to a rail (20a, 20b) of a railroad track (20) at a predetermined position (P), and a communication network (140) interfacing with the railroad crossing control system (10) and the wheel sensing system (120) and adapted to transmit data. The wheel sensing system (120) provides speed values of a rail vehicle travelling on the railroad track (20), wherein the speed values are transmitted to the railroad crossing control system (10) via the communication network (140) for producing a preemption signal for the traffic signal control system (110).
