System, Method, and Apparatus to Detect and Report Track Structure Defects
First Claim
1. A track defect detection system for detecting track defects while a train is in motion on railway tracks, comprising:
- at least one defect sensor configured to sense an acceleration of at least a portion of the train; and
at least one computer-readable medium comprising program instructions that, when executed by at least one processor, cause the at least one processor to;
(a) detect, while the train is in motion on the railway tracks, at least one track defect in the railway tracks based at least partially on the acceleration of the at least a portion of the train; and
(b) generate track defect data based at least partially on a location of the train when the at least one track defect is detected.

Abstract
A system, method, and apparatus for detecting and reporting track defects while a train is in motion on railway tracks includes at least one defect sensor configured to sense an acceleration of at least a portion of the train; and at least one computer-readable medium. The at least one computer-readable medium comprises program instructions that, when executed by at least one processor, cause the at least one processor to: detect, while the train is in motion on the railway tracks, at least one track defect in the railway tracks based at least partially on the acceleration of the at least a portion of the train; and generate track defect data based at least partially on a location of the train when the at least one track defect is detected.

11. A system for detecting and reporting track defects while a train travels over railway tracks, comprising:
-
a track defect detection device comprising at least one defect sensor; and a locomotive computer in communication with the track defect detection device, the locomotive computer configured to; (a) detect a track defect based at least partially on an acceleration sensed by the at least one defect sensor while the train is in motion; (b) generate track defect data comprising a magnitude and location of the track defect; and (c) communicate at least a portion of the track defect data to a remote server. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A method of detecting track defects in railway tracks while a rail vehicle is in motion, comprising:
-
monitoring an acceleration of at least a portion of a rail vehicle while the rail vehicle is in motion; determining, with at least one processer, if a track defect exists on the railway tracks based at least partially on the acceleration; and generating track defect data comprising a location of the track defect and at least one of the following;
a magnitude of the track defect, a severity of the track defect, the acceleration, a vertical acceleration, a lateral acceleration, an angular acceleration, a velocity of the rail vehicle, a characteristic of the track defect, a type of the track defect, or any combination thereof. - View Dependent Claims (19, 20, 21, 22, 23)
