摘要： A track switching arrangement for a track-based guided transportation system, wherein the track switching arrangement forms diverging pathways and enables vehicle-side switching of a vehicle in the guided transportation system. The track switching arrangement includes an upstream pathway; two downstream pathways; and a path switching transition region having the diverging pathways between the upstream pathway and the two downstream pathways. Each of the pathways includes track elements configured to interact with one or more respective bearings of the vehicle to provide levitation to the vehicle and/or guidance for the vehicle.

摘要： A radar monitoring system and a radar monitoring method for monitoring a traffic control zone involve installing two radars near the traffic control zone so that the radars emit radar waves covering the traffic control zone and serve as backups for each other; locating any object in the traffic control zone as a coordinate point with respect to a set of X and Y coordinate axes, and subjecting the X and Y coordinate axes of the two radars to axial normalization, so that an identical object in the traffic control zone is located by the first radar and the second radar at approximately the same coordinate point. An alert area is defined in the traffic control zone and an excluded area around a resident facility in the traffic control zone is excluded from the alert area. When an object in the alert area is determined as an obstacle, an alert is triggered.

摘要： An automated warning time inspection system (5) and method to test a warning time (45) at a railroad grade crossing (25) on each route for a train (30). The automated warning time inspection system (5) comprises a track circuit (12) configured to activate when a train (30) enters the track circuit (12), an event recorder (17) configured to record a first log time (35(1)) for activation of a crossing warning system (15), a camera (20) to detect a first motion detection indication (40(1)) in a motion detection zone (10) of the camera (20) if there is any motion and an island circuit (22) to detect a presence of the train (30) as the train (30) enters an island (42). The event recorder (17) to record a third log time (35(3)) for switch position indications when present. The event recorder (17) to record a fourth log time (35(4)) for activation of the island circuit (22). The camera (20) to detect a second motion detection indication (40(2)) in the motion detection zone (10) of the camera (20) after the activation of the island circuit (22) if there is any motion. The event recorder (17) to calculate and record a warning time (45) as a difference between the first log time (35(1) and the third log time (35(3)) and based on a motion detection before or after the activation of the island circuit (22) and whether the warning time (45) was more than or equal to a threshold time (50) and whether the train (30) was travelling more than or equal to a threshold speed (52) a passing or a failing of the warning time (45) inspection is logged into the event recorder (17) in a given route (55) of the train (30) travelling on the train track (7).

摘要： An anti-collision system for railcars and locomotives provides a distance ranging and worker coupling protection system utilizing remote-sensing radar techniques for use with a locomotive and railcar. The anti-collision system may include an object detector device attached to a railcar or a locomotive that detects objects in a path of the railcar and the locomotive and a train display device electrically connected to the object detector device. The anti-collision system may also include an emergency action device which enables a crew member to stop the railcar or locomotive without communication to a locomotive operator when a hazard is recognized. The object detector device may include a remote sensor, a radio, and a microprocessor programmed to include data-logging to record and log all data from the anti-collision system.

摘要： A facility inspection system prevents a normal part from being detected as an abnormal part caused by a deviation in an alignment due to a presence/absence of a moving object in detecting the abnormal part in a surrounding environment of a vehicle moving on a track. The system includes a photographing device, storage device, separation unit, an alignment unit, and a extraction unit. The photographing device photographs the surrounding environment of the moving vehicle. The storage device stores a reference alignment point cloud and a reference difference-extraction point cloud for each position on the track. The separation unit separates the alignment point cloud from a three-dimensional point cloud. The alignment unit aligns the reference alignment point cloud and the alignment point cloud and outputs alignment information. The extraction unit extracts a difference between the three-dimensional point cloud deformed based on the alignment information and the reference difference-extraction point cloud.

摘要： A control system includes a controller configured to control communication between or among plural vehicle devices that control operation of a vehicle via a network that communicatively couples the vehicle devices. The controller also is configured to control the communication using a data distribution service (DDS) and with the network operating as a time sensitive network (TSN). The controller is configured to direct a first set of the vehicle devices to communicate using time sensitive communications, a different, second set of the vehicle devices to communicate using best effort communications, and a different, third set of the vehicle devices to communicate using rate constrained communications.
