摘要:
The present disclosure is directed to a method for detecting a condition associated with a wheel on a train car. The method may include detecting a position of the wheel. The method may also include detecting a position of a rail on which the wheel travels. The method may further include comparing the position of the wheel relative to the position of the rail, and determining a wheel condition based on the comparison.

An emergency override system for a machine is disclosed. The emergency override system may have an input device configured to generate a stop signal. The emergency override system may also have a receiver configured to receive the stop signal. The emergency override system may further have a controller in communication with the receiver and connectable to a signal pin, which is configured to indicate a travel direction of the machine. The controller may be configured to stop a travel of the machine by applying a threshold voltage to the signal pin, when the receiver has received the stop signal.

A memory module is disclosed. The memory module may have an enclosure having a slot in a wall of the enclosure. The memory module may also have a device disposed within the enclosure. The memory module may further have a thermal cutoff disposed in the slot. The thermal cutoff may have a first end attached to the device. The thermal cutoff may also have a second end attached to a wire configured to electrically connect to the device. The thermal cutoff may disconnect the wire from the device when subjected to a threshold temperature.

A memory module is disclosed. The memory module may have an enclosure and a device disposed within the enclosure. The memory module may also have an orifice in a wall of the enclosure and a wire passing through the orifice. One end of the wire may be attached to the device. The memory module may further have a stopper attached to the wire. The stopper may be located abutting an outer surface of the enclosure. The memory module may also have a filler disposed within the enclosure. The filler may be configured to expand and be ejected out of the orifice when subjected to a threshold temperature. The filler may also be configured to push the stopper away from the outer surface and disconnect the wire from the device.

The present disclosure is directed to a dragger. The dragger may have a plurality of sensors configured to be located adjacent a railroad track. Each of the plurality of sensors may be oriented at an angle relative to a horizontal plane. The dragger may also have a controller in communication with the plurality of sensors. The controller may be configured to receive signals from the plurality of sensors, determine a parameter based on at least one of the received signals, and detect a fault condition when the parameter exceeds a threshold.

The present disclosure is directed to a temperature detector for detecting a temperature of a component. The temperature detector may receive a first signal indicative of the temperature of the component, with the first signal being received from a first type of temperature sensor. The temperature detector may further receive a second signal indicative of the temperature of the component, with the second signal being received from a second type of temperature sensor different from the first type of temperature sensor. The temperature detector may combine the first and second signals to generate an output indicative of the temperature of the component.
摘要:
A test apparatus for testing an IR sensor of train undercarriage temperatures is disclosed. The IR sensor may be used to obtain infrared IR emission data by sensing a wheel or a wheel bearing of a rail vehicle. The test apparatus may comprise a heat emitter for supplying IR emissions at a reference temperature to the IR sensor. A support may support the heat emitter at a position spaced from the passage of the rail vehicle and in an orientation for directing the IR emissions at the IR sensor.
摘要:
The present disclosure is directed to a system and method for identifying a hot bearing. A processor may be configured for receiving a plurality of infrared (IR) signals emitted by a bearing as the bearing passes through a view window being monitored by one or more IR sensing elements positioned to receive IR radiation emitted from a target area of the bearing. The processor may extract IR data from IR signals emitted from an area within the target area of the bearing defined by a narrow window extending along a longitudinal axis for a length corresponding to substantially an entire length of the bearing. The processor may also establish a characteristic thermal profile from the extracted IR data, the characteristic thermal profile exhibiting identifiable boundaries of an area of interest on the bearing. The processor may compare temperatures of the bearing within the area of interest to a threshold, and produce an alarm signal if temperatures of the bearing within the area of interest exceed the threshold.
摘要:
A recording system may include a camera configured to record images including a first image and a storage device configured to store the images. The recording system may include a controller configured to identify at least one vertical line contained in the first image and determine whether the first image is indicative of a probable event area based on the identification of the at least one vertical line. The controller may be configured to command the camera to record the images at a first quality if the first image is indicative of a probable event area. The controller may also be configured to command the camera to record images at a second quality if the first image is not indicative of a probable event area. The images recorded at the second quality occupy less memory in the storage device than the images recorded at the first quality.
