Abstract
A monitoring system and method may receive detection times at which passage of one or more vehicle systems by a detection device disposed along a route is detected. Locations of the one or more vehicle systems at different times may be received from one or more location sensors disposed onboard the one or more vehicle systems. The locations of the one or more vehicle systems when the one or more vehicle systems were detected by the detection device may be determined by comparing the detection times with the different times associated with the locations. A condition or state of the detection device can be determined by comparing the locations that are determined by the controller with a device location of the detection device.
Claims20
A monitoring system comprising:
- a controller configured to receive detection times at which passage of one or more vehicle systems by a detection device disposed along a route is detected, the controller also configured to determine sensed locations of the one or more vehicle systems when the one or more vehicle systems were detected by the detection device, the controller configured to receive the sensed locations from one or more location sensors of the one or more vehicle systems, the controller configured to determine the sensed locations when the one or more vehicle systems were detected by determining the sensed locations received by the one or more location sensors at the detection times,
- the controller configured to identify a condition or state of the detection device by comparing the sensed locations determined by the controller at the detection times with a device location of the detection device.
A method comprising:
- determining times at which one or more vehicle systems are detected by a detection device disposed along a route;
- determining locations of the one or more vehicle systems at the times the detection device detected the one or more vehicle systems;
- and
- identifying a condition or state of the detection device by comparing the locations that are determined by a controller at the determined times with a device location of the detection device.
A monitoring system comprising:
- a controller configured to receive a detection time at which passage of one or more vehicle systems by a detection device disposed along a route is detected, the controller also configured to determine a sensed location of the one or more vehicle systems when the one or more vehicle systems were detected by the detection device, the controller configured to receive the sensed location from one or more location sensors of the one or more vehicle systems at the detection time,
- the controller configured to compare the sensed location determined by the location sensor of the one or more vehicle systems at the detection time with a device location of the detection device and determine a difference between the sensed location and the device location,
- wherein if the difference between the sensed location and the device location is greater than or equal to a threshold distance, the controller is configured to identify a degraded state of the monitoring system and if the difference between the sensed location and the device location is less than the threshold distance, the controller is configured to identify an operable state of the monitoring system.
