摘要: In a system and method for operating a system having a rail, a stationary unit, rail-guided mobile parts, and a slotted hollow waveguide, either a first one of the mobile parts or the stationary unit functions as a transmitter, and a second one of the mobile parts functions as a receiver. The transmitter is configured for the simultaneous transmission of an electromagnetic signal and an acoustic signal, e.g., at a first instant. The receiver, which is set apart from the transmitter, is configured to detect the arrival of the electromagnetic signal at a second instant and to detect the arrival of the acoustic signal at a third instant. The second mobile part has an evaluation unit which is configured to determine the distance between the transmitter and the receiver based on the acquired second and third instants.

摘要: A system for dynamically adjusting a configuration of an intra-train communication network includes an electronic device and a computer-readable storage medium. The computer-readable storage medium has one or more programming instructions that, when executed, cause the electronic device to receive one or more parameters values associated with a train consist, determine whether a potentially adverse condition that would affect intra-train communication for the train consist is anticipated based on at least a portion of the received parameters, in response to determining that the potentially adverse condition is anticipated, identify one or more updated network parameter settings that will assist in maintaining intra-train communication of the train consist during an occurrence of the potentially adverse condition by executing a machine learning model, and implement the identified one or more updated network parameter settings.

摘要: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for monitoring vehicles traversing a dedicated roadway that includes an at-grade crossing. In some implementations, a system includes a central server, a gate system, and sensors. The gate system provides access to an at-grade crossing for vehicles. The sensors are positioned in a fixed location relative to a roadway, the roadway including the at-grade crossing. Each sensor can detect vehicles on the roadway. For each vehicle, each sensor can generate sensor data and observational data from the generated sensor data. Each sensor can determine a likelihood that the detected vehicle will approach the at-grade crossing by comparing the likelihood to a threshold. In response, each sensor can transmit data to the gate system that causes the gate system to allow the autonomous vehicle access to the at-grade crossing prior to the autonomous vehicle reaching the gate system.

摘要: An automated on-vehicle rail vehicle control system has an on-vehicle set point value detection unit, an automated train operating system, a driving and braking unit, and additional sensors for detecting environment-related information. The on-vehicle set point value detection unit is configured to determine, based on on-vehicle positioning and map data as well as sensor data from the additional sensors, operative set point values for the control mode and the current driving mission of the rail vehicle. The automated train operating system is configured to generate driving and braking commands based on the set point values of the on-vehicle set point value detection unit. The driving and braking unit is configured to carry out traction and braking operations based on the driving and braking commands so determined. There are also described a rail vehicle and a method for the automated control of a rail vehicle.

摘要: Intermodal vehicles may be loaded with items and an aerial vehicle, and directed to travel to areas where demand for the items is known or anticipated. The intermodal vehicles may be coupled to locomotives, container ships, road tractors or other vehicles, and equipped with systems for loading one or more items onto the aerial vehicle, and for launching or retrieving the aerial vehicle while the intermodal vehicles are in motion. The areas where the demand is known or anticipated may be identified on any basis, including but not limited to past histories of purchases or deliveries to such areas, or events that are scheduled to occur in such areas. Additionally, intermodal vehicles may be loaded with replacement parts and/or inspection equipment, and configured to conduct repairs, servicing operations or inspections on aerial vehicles within the intermodal vehicles, while the intermodal vehicles are in motion.

摘要: Methods and apparatus for detecting of spoofing or jamming activities near a train or other railroad assets uses a message sent from each of a plurality of base stations receiving a wireless packet transmitted by a radio of a railroad asset that reports the PNT information determined by the radio using GNSS and a timestamp for the time of arrival of wireless packet at the base station. The position of the asset is then calculated based on the time arrival of the wireless packet at each base station and compared to the reported position. A warning is generated if the difference exceeds a predetermined threshold.

摘要: Methods and systems for selection of a control speed for a remote-controlled vehicle based on rulesets applied to control nodes within a viewing window. In embodiments, a viewing window including control nodes, each having a having ruleset defining operating conditions associated therewith, may be determined. The ruleset for a control node may define operating limitations (e.g., speed limitations, orientation limitations, etc.) at the control node. In embodiments, a control speed plan for the viewing window may be generated based on the operating conditions for each control node within the current viewing window based on the limitations associated with each control node. The control speed plan may include an optimal control speed at each control node within the viewing window and a speed profile indicating an acceleration or deceleration curve to be followed through each of the optimal control speeds in the control speed plan when executing the control speed plan.
