Multi-function dragger

摘要

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.

1. A dragger, comprising:
a plurality of sensors configured to be located adjacent a railroad track, each of the plurality of sensors being oriented at an angle relative to a horizontal plane; and a controller in communication with the plurality of sensors, the controller being configured to:
receive a first set of signals from the plurality of sensors;select a plurality of signals from the first set of signals based on a predetermined fault condition to form a second set of signals, the second set of signals corresponding to a combination of sensors from the plurality of sensors;determine a parameter based on characteristics of a combined signal obtained from the second set of signals;detect a fault condition when the parameter exceeds a threshold;identify a type of the fault condition based on the combination of the sensors corresponding to the second set of signals; and trigger an alarm corresponding to the identified fault condition.
