摘要： An arrangement for optically capturing a railroad track includes a carrier device, a camera, and two light sources. The arrangement is mountable on a carrier vehicle that is movable on rails. The alignment of the two light sources and thus the central axes of the emitted light radiation or waves enclose an acute angle with a longitudinal axis of the rail. The light sources are coupled with the camera via control signal lines. The triggering or activation of the light sources is effected via the control signal lines by a predefined control signal. This achieves detailed, sharp image contours that allow high-precision image evaluation and object recognition at the highest possible working speed.

摘要： In one embodiment, a method includes identifying, by an image detection tool, a tank within an image of a railway environment and identifying, by the image detection tool, a railroad track within the image of the railway environment. The method also includes determining, by the image detection tool, a distance between the tank and the railroad track and comparing, by the image detection tool, the distance between the tank and the railroad track to a predetermined threshold distance. The method further includes determining, by the image detection tool, that the tank presents a hazard to the railway environment in response to comparing the distance between the tank and the railroad track to the predetermined threshold distance.

摘要： System, methods, and machine-readable media to facilitate monitoring and control of a railway maintenance assembly are disclosed. A railway workhead component monitor may be adapted to be disposed at a railway maintenance assembly. The railway workhead component monitor may be configured to perform one or a combination of the following. One or more conditions of at least a portion of the railway maintenance assembly may be monitored. Based at least in part on the monitoring, a plurality of monitoring data corresponding to operations of the railway maintenance assembly may be stored. Reporting data may be generated based at least in part on the stored plurality of monitoring data. A wireless communication may be transmitted toward a railway device controller that is remote from the railway maintenance assembly, the wireless communication including the reporting data.

摘要： The present disclosure includes systems, devices, and methods for identifying, detecting, and/or tracking rail features. In some aspects, a system includes a camera and a computer having at least one memory, at least one processor configured to receive a plurality of images from the camera, and for each of the images: assigning a location identifier and identifying one or more rail features that correspond to one of a plurality of predetermined rail features. In some systems, the at least one processor is configured to determine a location of each of the one or more identified rail features.

摘要： A portable, single-fixation, magnetic derailment mitigation device may be fixed on a rail track for measuring the deflection of the rail track. The magnetically fixing device is used for measuring vertical track deflection (sleeper voids), horizontal track deflection, ambient and rail temperature, rail angle, vibration, displacement, and location. The derailment mitigation device sends digital notifications and/or alarms during the live train and/or freight operations to help prevent derailments, rail buckles, breaks, and pull apart. The measured data and/or all events obtained from the derailment mitigation device is stored in the data storage such as cloud storage and viewed from any smart devices.

摘要： A track measuring vehicle for recording a track geometry of a track includes a vehicle frame which has rail undercarriages and is mobile on two rails of a track. The vehicle also includes a first measuring base on which are arranged an inertial measuring unit and, for a position determination relative to each rail, at least one contact-less position measuring device. A lowerable second measuring base has measuring running wheels designed to be set upon the rails and is connected to the first measuring base via compensation measuring devices.

摘要： A train jolt determination system includes: a portable terminal capable of being held in a train and configured to acquire position information on the train, detect the acceleration of the train, and capture an image of the scene around the train; a storage section configured to associate the position information, acceleration information indicative of a detection result of the acceleration, and image information indicative of the scene and store the position information, the acceleration information, and the image information; and a jolt amount calculation section configured to calculate an amount of jolting of the body based on the acceleration information. In a case where the body is determined to have jolted based on the amount of jolting, position information associated with acceleration information used for the determination of jolting is supplemented with image information associated with the acceleration information, and a position where the body has jolted is estimated.
