摘要： A computer-implemented method for identifying a defect of a passing train via acoustic monitoring. The method may include the steps of: receiving data from the passing train within a zone of observance using an array of microphone assemblies of an acoustic monitoring system that are positioned around a section of the track. The method may further include processing the data to determine pressure levels received by each of the array of microphone assemblies. The method may further include calculating a theoretical pressure level for a plurality of points within a three-dimensional space for each microphone of the array of microphone assemblies. The method may further include determining one or more locations within the three-dimensional coordinate space that represents an origin of a noise source indicating the defect. And the method may further include determining a type of defect based on the acoustic signatures.

摘要： 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.

摘要： A system for detecting one or more vehicles, such as a train, on a rail track, includes at least one optical conductor extending near and parallel to the rail track with a light source and light detector coupled thereto. One or more sensors are coupled to the rail track and include the light conductor, which sensors affect the light attenuation in the light conductor locally upon the presence of the vehicle. The sensor includes a free elongated element, which is connected to the mass of the sensor housing via an elastic hinge connection. One end of the element lies against the light conductor running through the sensor housing, which one end subjects the conductor to a microbending in dependence on displacement of the rail. The elongated element is a pin which runs through a drilled block which is integral with the elastic hinge connection, and at its other end is provided with an outstanding pick-up arm of which the end rests on a contact surface of the fixed substructure of the rail such that the sensor is adapted to detect a displacement or sag of the rail. The arm end may also be free or the pick-up arm may be eliminated such that the sensor is adapted to detect vibrations of the rail. For the purpose of measuring modal noise, the system may comprise an additional optical conductor disposed in close contact with the rail. The conductor may be suspended in a tube provided with perforated partitions, the optical conductor having vibratory masses attached to it.

摘要： A method and apparatus for detecting an impact sound, such as a sound caused by a railroad vehicle approaching a construction location. The apparatus comprises an arrangement for detecting impact sound or vibrations with a receiver mounted at the rail, for example, and, further, an evaluation circuit for processing the vibrations and triggering a warning signal when the intensity of the receiver-output signal continuously increases, for example, when the intensity in a predetermined frequency range passes through predetermined threshold values during predetermined times. Thus, an approaching railroad vehicle can be positively detected by monitoring a continuously increasing sound or vibration which is propagated in the rails.

摘要： A method for operating a locating device having a waveguide laid along a stretch of track to locate a rail vehicle on the stretch of track includes injecting electromagnetic pulses into the waveguide in succession or series and receiving and evaluating backscattering patterns produced by backscattering of the electromagnetic pulse for each emitted pulse. A vibration device located in the region of the stretch of track at a known position is activated at a predefined activation time and a vibration causing backscattering of the electromagnetic pulse is thereby produced at the known position, the duration between the activation time and the receipt of the backscattering pattern indicating the vibration is measured, and the measured duration is used to check the functionality or operation of the locating device or to calibrate the locating device. A locating apparatus for locating a rail vehicle along a stretch of track is also provided.

摘要： Each approach detection track circuit in a multiple track stretch crossed by one or more highways is sequentially connected to a track energy source, including a distance monitor means, by a multiplexing means, shown as a bank of relays operated in repeated cycles by a central process controller. The distance monitor, as it is sequentially connected to each track circuit, provides a distance proportional signal to the central process controller for a train approaching along any track. The process controller registers the detection of the approaching train and determines its continued approach by successive distance measurements received from the same track circuit. When the train is determined to be a predetermined warning time or distance from the crossing, the process controller actuates the highway warning signals. Multiplexing the connections of the track circuits to the distance monitor allows the use of a single set of centralized highway crossing apparatus including the distance monitor and the process controller.
