Abstract
An inspection system for use with a rail vehicle includes a sensor configured to be deployed onboard the rail vehicle for inspection of wayside rail equipment to determine operability or alignment of the equipment.
Claims15
An inspection system, comprising:
- a first sensor system configured to be operably disposed onboard a rail vehicle, wherein the first sensor system comprises a sensor that is configured to generate sensor signals indicative of wayside rail equipment inspected by the sensor;
- a control module configured to be operably coupled to the sensor and operative to determine at least one of operability or alignment of the wayside rail equipment based on the sensor signals received from the sensor;
- and
- a database configured to receive and store at least one of results of wayside rail equipment inspections or locations of wayside rail equipment to be inspected, wherein:
- the database includes plural designated values respectively corresponding to plural devices of the wayside rail equipment to be inspected along a route to be traveled by the rail vehicle, each designated value indicative of a determined amount of light emitted from the device corresponding to the designated value when the device is operational and properly aligned;
- the sensor is configured to generate the sensor signals corresponding to light emitted from the plural devices of the wayside rail equipment and sensed by the sensor as the rail vehicle travels along the route;
- and
- the control module is configured to perform a comparison of the designated values to the sensor signals and to generate output signals based on the comparison.

An inspection system, comprising:
- a first sensor system configured to be operably disposed onboard a rail vehicle, wherein the first sensor system comprises a sensor that is configured to generate sensor signals indicative of wayside rail equipment inspected by the sensor;
- and
- a control module configured to be operably coupled to the sensor and operative to determine at least one of operability or alignment of the wayside rail equipment based on the sensor signals received from the sensor;
- wherein:
- the first sensor system is a cab-mounted video system, the sensor of the first sensor system comprising a video camera of the cab-mounted video system;
- the camera is aligned to view a sensor aperture of the wayside rail equipment when the rail vehicle is traveling along a route, the wayside rail equipment being disposed on a wayside of the route;
- and
- the control module is configured to assess the sensor signals generated by the video camera for determining if the video camera has captured light emitted through the sensor aperture of the wayside rail equipment, the wayside rail equipment configured to emit signal light along a first axis disposed at a non-zero degree angle relative to an axis of the sensor aperture.

An inspection system, comprising:
- a reflector configured be affixed to wayside rail equipment;
- wherein the reflector is configured, when affixed to the wayside rail equipment, to be detected by a sensor mounted to a rail vehicle, and is configured to allow the rail vehicle to inspect the wayside rail equipment to assess at least one of alignment or operability of the wayside rail equipment.
An inspection system, comprising:
- wayside rail equipment having a cowl with a primary light opening and a sensor aperture;
- wherein the sensor aperture is configured to emit light for detection by a sensor mounted to a rail vehicle to allow the rail vehicle to assess at least one of alignment or operability of the wayside rail equipment.
An inspection system, comprising:
- a sensor configured to be operably disposed onboard a rail vehicle and to generate sensor signals indicative of wayside rail equipment inspected by the sensor;
- and
- a control module configured to be operably coupled to the sensor and operative to determine at least one of operability or alignment of the wayside rail equipment based on the sensor signals;
- wherein:
- the sensor is aligned to view a sensor aperture of the wayside rail equipment when the rail vehicle is traveling along a route, the wayside rail equipment being disposed on a wayside of the route;
- and
- the control module is configured to assess the sensor signals for determining if the sensor has captured light emitted through the sensor aperture of the wayside rail equipment, the wayside rail equipment configured to emit signal light along a first axis disposed at a non-zero degree angle relative to an axis of the sensor aperture.
