    摘要: A sensor device includes an audio sensor and a wireless communication module. The audio sensor is configured to be mounted on a railroad vehicle. The audio sensor is configured to (i) monitor sounds emanating from one or more wheels of the railroad vehicle as the railroad vehicle moves along a track and (ii) generate sound data associated with the monitored sounds emanating from the one or more wheels. The wireless communication module is configured to transmit a broken wheel signal responsive to a determination that a portion of the generated sound data is indicative that a first one of the one or more wheels is damaged or broken.

    摘要: A system for monitoring the state of a wheel of a rail vehicle includes an acquisition unit that is designed, upon a braking event, to acquire at least one operating parameter for the wheel, an evaluation unit that is designed to determine a temperature value for the wheel based on the acquired operating parameter; and a control unit that is designed to generate and to output an output on the basis of the determined temperature value. It furthermore relates to a method for monitoring the state of a wheel of a rail vehicle, in which, upon a braking event, at least one operating parameter for the wheel is acquired, a temperature value for the wheel is determined based on the acquired operating parameter and an output is generated and output on the basis of the determined temperature value.

    摘要: In a method of determining a radius or diameter of a train wheel, a camera mounted on a train acquires first and second images (pictures) of first and second objects spaced along a path being traveled by the train. Matches are then determined between the first and second objects appearing in the first and second acquired images and representations (pictures) of the first and second objects appearing in prerecorded images included in a track database that include corresponding first and second geographical locations. A distance L traveled by the train between the first and second geographical locations is determined and a sum C of electrical pulses generated by an encoder coupled to the train wheel during travel of the train the distance L is determined. Based on the distance L and the sum C, a diameter or radius of the wheel is determined.

    摘要: A railroad wheel impact load detection test panel includes a secondary instrumentation rail proximate a field side of a primary or running rail of a section of railroad track, and elevated a prescribed distance so that the wheels of a rail car traverse the instrumentation rail within the test panel. The instrumentation rail includes an optical strain gauge to sense the wheel impact load. The sensed impact data is correlated with wheel damage signatures to identify wheels to be restored or replaced before failure occurs.

    摘要: A system is provided that includes a detection circuit having a first and second sensor. The first sensor is configured to measure a rotational speed of a first wheel. The second sensor is coupled to a vehicle chassis and configured to measure a position over time of the vehicle chassis. The system further includes a controller circuit configured to determine a shock frequency based on the position of the vehicle chassis. The controller circuit is further configured to determine a condition (e.g., an anomalous condition) of the first wheel based on the shock frequency and the rotational speed, and may be further configured for vehicle control based on the determined condition.

    摘要: The present invention relates to a method for identifying and locating a defect in a train wheel or an axle of a train as the train moves along a rail track, the method comprising the steps of: sampling magnetic field measurements obtained from a plurality of magnetometer sensors so arranged to be in proximity to a moving wheel or an axle, the sensors arranged to span at least a length sufficient to obtain the magnetic field measurements from the entire wheel or the axle during one complete revolution of the wheel or the axle; and identifying and locating a defect in the wheel or the axle when a sampled magnetic field measurement is equal to or exceeds a threshold value.

    摘要: The systems and methods described herein include monitoring systems and methods that monitor speeds of a motor of a vehicle represented as a pulse signal indicative of a rotational position of the motor. The systems and methods include receive a pulse signal from a speed sensor coupled to a traction motor. The pulse signal is indicative of a rotational position of the traction motor. The systems and methods include analyze the pulse signal to identify per-revolution signal reoccurrences that meet designated criteria, and determine a defect based on the per-revolution signal reoccurrences that are identified. The defect is one or more of a wheel defect, a bearing defect, or a gear defect.
