摘要： METHOD AND SYSTEM FOR HEALTH ASSESSMENT OF A TRACK CIRCUIT AND/OR OF A TRACK SECTION The invention concerns 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 said 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. The calculated health indicators are for example used for predictive maintenance of the track section and/or of the track circuit. Figure 1 I- El

摘要： METHOD, SYSTEM, AND SOFTWARE CODE FOR CALIBRATION OF RAIL TRACK CIRCUITS, AND RELATED RAIL TRACK CIRCUIT Method, system and software code for calibrating a rail track circuit comprising a plurality of rails coupled to form a track section having a predefined length, a transmit processing unit coupled to the track section at a first end of the track section, and a receive processing unit coupled at the second end of the track section. A transfer function between a transmit voltage applied by the transmit processing unit at the track section and a resulting receive current detected at the receive processing unit is first determined and then applied to the rail track circuit for automatic initial calibration or recalibration.

摘要： A system and method for controlling a level crossing of a railway track installation is provided. The railway track installation includes at least one track. The system includes at least two magnetometers associated with the at least one track (2a) and placed at corners of a crossing area between the at least one track and a road. The system also includes a level crossing control unit configured for receiving data from the magnetometers. Each magnetometer is arranged to detect a respective magnetic field vector of the earth's magnetic field and to send data representative of said magnetic field vector to the control unit, the control unit being configured to elaborate said data to detect changes in the magnetic field vectors due to the presence of a train in the crossing area and to control the level crossing as a function of said detected changes.

摘要： A wayside communication system for transmitting coded current signals through running rails of a railroad track between wayside control devices. A power line common to the wayside control devices is used as the return path for the current signals. The system features train and broken rail detection. The system allows sending signals long distances since rail to rail current leakage is no longer an issue.

摘要： VIBRATION MONITORING SYSTEM AND METHOD A vibration monitoring system includes an acoustic device that outputs an analog signal to a fiber cable for calibration and location verification. The acoustic device utilizes GPS or communication from wayside bungalow equipment to verify GPS location or real-time clock information. The wayside bungalow contains communication equipment that interfaces with the acoustic device and relays health information to a sensing processor. The sensing processor is configured to detect the acoustic signal output by the acoustic device at a known location and verifies that the cable and device have not moved location by comparing the signal level received against a threshold stored in memory. When the threshold is exceeded, the sensing processor sends an alert that the fiber optic cable or acoustic device at the location have changed. C) C) 0) U) C: o 0 ca CA)

摘要： A system for controlling a level crossing comprising: - one or more transceivers located in proximity of a level crossing area on a first side of a 5 railway track; - one or more corresponding passive reflective targets located in proximity of the level crossing area on a second side of the railway track opposite to the first side where each transceiver is located; - a control unit connected to each transceiver; 10 wherein - each target is arranged to receive RF signals coming from each transceiver and to send back corresponding reflected signals; - each transceiver is arranged to elaborate said reflected signals so as to calculate predetermined parameters values; 15 - the control unit is arranged to acquire said parameters values from each transceiver and to elaborate them so as to detect the presence of a train in an area around the level crossing area and, in case of presence of said train, to send a warning message and/or close bars of the level crossing. 20 Figure 1 E) 1101 lb

摘要： A method for controlling a level crossing of a railway track comprising at least the following steps of: - providing a train having an onboard processor arranged to communicate with a wayside processor associated to a level crossing, said train extending between a forward end and a rear end; - moving the train forward along the railway track in a predetermined direction so that the forward end and the rear end move correspondingly along the railway track in the same direction; - lowering down gates of the level crossing when train is at a predetermined distance upon detection of the train approaching of the level crossing; - when the forward end passes over a first reference point defining the beginning of an island area associated to the level crossing, sending a first message from the onboard safety processor towards the wayside processor to inform that the train is approaching the corresponding level crossing; - maintaining down gates of the level crossing; - when the rear end passes over a second reference point defining the end of the island area, sending a second message from the onboard safety processor to the wayside processor to inform that the train has left the corresponding level crossing; and - lifting the gates of the level crossing.
