摘要:
Systems and methods for detecting in motion railcar seismic data generated by defective railcar axles of a train traveling on a track. The method uses two or more seismic sensors on the side of the track to capture seismic noise generated by railcar wheels. A wheel that exceeds a preset seismic noise threshold in amplitude, will trigger a wheel tracking algorithm that calculates seismic phase shift data related to the actively tracked wheel noise level, to determine the precise location, in real time, of the faulty wheel carriage while moving. Knowing the precise location of the tracked wheel allows the system to isolate the railcar and capture the railcar and wheel carriage identification information.Subsequently, a railcar log is made on a computer database with the railcar identification information and made available to control centers via ground or satellite links.

A method includes determining a location of a vehicle system traveling on a track during a first trip relative to a curve in the track. The method also includes monitoring a temperature profile at a contact interface between a wheel of the vehicle system and a rail of the track that contacts the wheel as the vehicle system traverses the curve in the track. The temperature profile is based, at least in part, on a first speed profile of the vehicle system during the first trip. The method further includes analyzing the temperature profile to detect a flanging event between the wheel and the rail as the vehicle system traverses along the curve in response to the temperature profile indicating that a flange of the wheel engages a side of the rail.

A system for identifying a fault in sensors disposed in two or more locomotives of a consist is disclosed. The system includes a first sensor, disposed in a first locomotive, configured to detect a first value of a parameter associated with operation of the first locomotive. The system includes a second sensor, disposed in a second locomotive, configured to detect a second value of the parameter associated with operation of the second locomotive. The system includes a receiving unit, in communication with the first sensor and the second sensor, configured to receive the first value and the second value of the parameter. The system includes a controller configured to compare the first value with the second value of the parameter, and identify the fault in one of the first sensor and the second sensor based on the comparison between the first value and the second value.

A protective shroud is provided for enveloping light radiating from a light emitter used with a sensor system for mapping of a railway track. The protective shroud includes: a rigid body having a frame and at least one opaque panel connected to the frame, the rigid body defining at least a first portion of a light radiation zone; a skirt formed of high density fibers extending from adjacent a bottom edge of the at least one opaque panel to adjacent a ground surface; at least one light emitter connected to the rigid body adjacent a top edge of the rigid body to emit light radiation into the light radiation zone; and at least one sensor connected to the rigid body adjacent the top edge of the rigid body to sense the light emitted from the at least one light emitter.

A control apparatus mounted on a railcar including a plurality of wheelsets includes: a torque basic value setting portion configured to set a basic value of torque applied to each of the plurality of wheelsets; an adhesion determining portion configured to determine whether or not each of the plurality of wheelsets adheres to a rail; and a torque correcting portion configured to correct the basic value of the torque to obtain a corrected value that is smaller than the basic value. The plurality of wheelsets includes one or more specific wheelsets and one or more general wheelsets other than the specific wheelsets. The torque correcting portion calculates the corrected value of the torque, applied to the general wheelset, in accordance with a first rule and calculates the corrected value of the torque, applied to the specific wheelset, in accordance with a second rule different from the first rule.
摘要:
A derail alarm system for notifying a tamping machine operator that a tamping projector buggy is in a derailed condition. A rail sensor with an ultrasonic beam attaches to a tamping projector buggy to sense alignment with a metal rail. When the ultrasonic sensor detects an out-of-tolerance condition, aural and red-LED light visual indications are electronically provided to the tamping machine operator. The tamping machine operator may disable the aural indication and change the red-LED indication to an amber-LED indication until the ultrasonic sensor detects an in-tolerance condition. A limit switch deactivates the cradle sensor when the tamping projector buggy is raised and stored in the travel position for a higher speed transport condition.
摘要:
A train control system comprising a vital brake interface unit that is disposed between the train control processors and the braking system. The brake interface unit ensures that any failure in the control processors or the interface itself is detectable and, when detected, causes the system to fail safely (i.e., the train's brakes are applied). By virtue of the use of redundant circuitry paths, the vital braking interface unit enables real-time verification of system circuitry without actually applying the train's brakes.

A method for providing a diagnostic message associated with at least one process in a rail vehicle, includes using at least one device of the vehicle to carry out the process, using a diagnostic device of the vehicle associated with the process to produce at least one diagnostic report, and using a data acquisition device to acquire at least one environment dataset. In order to keep the time required for the preprocessing of the information content short despite high data volume, the data acquisition device includes at least one image and/or sound-recording unit. Image and/or sound data being recorded by the image and/or sound-recording unit, the environment dataset containing image and/or sound data, the diagnostic report and the environment dataset are combined by an aggregation unit of the vehicle to produce the diagnostic message. A rail vehicle having an apparatus providing a diagnostic message is also provided.

A method of resetting a control system of a machine is disclosed. The method may include observing a condition of the machine from off-board the machine and determining a fault associated with the control system based on the condition. The control system may include a controller onboard the machine and at least one breaker in communication with the controller. The method may further include generating a command from off-board the machine directing the controller to attempt to automatically reset the control system. Automatically resetting the control system may include cycling the at least one breaker or rebooting the controller.
