Patent ID: 10392037

Abstract:
An automated warning time inspection system and method to test a warning time at a railroad grade crossing on each route for a train. The automated warning time inspection system comprises a track circuit configured to activate when a train enters the track circuit, an event recorder configured to record a first log time for activation of a crossing warning system, a camera to detect a first motion detection indication in a motion detection zone of the camera if there is any motion and an island circuit to detect a presence of the train as the train enters an island. The event recorder to record a third log time for switch position indications when present. The event recorder to record a fourth log time for activation of the island circuit. The camera to detect a second motion detection indication in the motion detection zone of the camera after the activation of the island circuit if there is any motion. The event recorder to calculate and record a warning time as a difference between the first log time and the third log time and based on a motion detection before or after the activation of the island circuit and whether the warning time was more than or equal to a threshold time and whether the train was travelling more than or equal to a threshold speed a passing or a failing of the warning time inspection is logged into the event recorder in a given route of the train travelling on the train track.
