    Abstract: A train control system uses artificial intelligence for maintaining synchronization between centralized and distributed train control models. A machine learning engine receives training data from a data acquisition hub, a first set of output control commands from a centralized virtual system modeling engine, and a second set of output control commands from a distributed virtual system modeling engine. The machine learning engine compares the first set of output control commands and the second set of output control commands, and trains a learning system using the training data to enable the machine learning engine to safely mitigate any difference between the first and second sets of output control commands using a learning function including at least one learning parameter.

  • Patent number: 11390306
    Abstract: Disclosed are a method and a system for multi-objective optimization of urban train operation. Firstly, speed limit information, slope information and curve radius information of a real train route are obtained, a section is segmented into non-equal sub-sections according to the above information about actual line characteristics, and then a longitudinal dynamics model of the train is constructed in combination with basic vehicle data of the train. Next, energy consumption of the train operation, section operation time, actual parking positions, and rates of acceleration change are calculated, so as to construct a multi-objective optimization model of train operation. Afterwards, a multi-objective differential evolution algorithm is used to solve the multi-objective optimization model, in order to obtain a Pareto optimal solution set of each operation district. Finally, an optimal solution is obtained which takes all objectives into comprehensive consideration, and an optimal train speed curve is generated.

  • Patent number: 11352937
    Abstract: A marine drive is for propelling a vessel in body of water. The marine drive has a powerhead, a crankcase on the powerhead, and a cooling system that pumps a first flow of cooling water from the body of water through a powerhead cooling conduit for cooling the powerhead and in parallel pumps a second flow of cooling water from the body of water through a crankcase cooler for cooling the crankcase and lubricant in the crankcase. A valve controls the second flow of the cooling water to the crankcase cooler. The valve is normally positioned in a closed position, which inhibits the second flow of cooling water to the crankcase cooler and thereby reduces condensation of water from the lubricant in the crankcase. The valve is moved into an open position upon operation of the powerhead at or above a threshold speed, which permits the second flow of cooling water to the crankcase cooler and thereby cools the lubricant in the crankcase.

  • Patent number: 10967888
    Abstract: At an on-board control unit of an on-board apparatus, a coupling detecting unit detects coupling of a failure train with respect to the own train. Then, in the case where detection is performed by the coupling detecting unit, a train occupancy range calculating unit updates train length information using the number of vehicles of the failure train and uses the updated train length information to calculate train occupancy range information. Further, a traveling control unit controls traveling and stop of the own train as a series of coupled trains in the case where detection is performed by the coupling detecting unit.

  • Patent number: 10933897
    Abstract: A method secures a railroad crossing which allows a timely securing of the railroad crossing, and is particularly efficient and reliable. The method proceeds in such a way that sensor data relating to a rail-borne vehicle approaching the railroad crossing are detected by a track-side sensor device. The sensor data contains at least the current speed of the rail-borne vehicle. The detected sensor data are transmitted by the track-side sensor device to a stationary control device. A switch-on time is determined by the stationary control device taking into account the transmitted sensor data and route data. Upon reaching the switch-on time, the securing of the railroad crossing is initiated by the stationary control device. After the railroad crossing has been successfully secured, a travel permission that extends beyond the railroad crossing is determined by a control device of a train control system, and is transmitted to the rail-borne vehicle.

  • Patent number: 10899373
    Abstract: A safety method for a railway network that is divided into section segments by way of section elements and which can be traveled by vehicles in accordance with data from a section atlas. The vehicles request steps for allocation as a track element from selected section elements. Each of the selected section elements autonomously allocates itself as a track element under specified conditions for each requesting vehicle. In order to be able to inform the vehicle or the vehicle operators thereof about changed section characteristics better and more quickly, for the section elements, the vehicles store manually entered and/or manually released dynamic driving operation data as a dynamic component of the section atlas in parts related to the section elements.

  • Patent number: 10858018
    Abstract: A train information management device sends and receives information to and from both a train-controlling in-vehicle wireless station for controlling an operation of a train, and a door-controlling in-vehicle wireless station for controlling vehicle doors. The device includes a wireless train control unit, an automatic operation unit, and a door control unit. The wireless train control unit receives route information represented by a consecutive block sequence and information on a stop limit location that the train may reach without hindering a preceding train, and if this route information includes a station block number, consults an in-vehicle database to extract, before the train arrives at a platform, an arrival track where the train is to stop, a stop target location at a stop station dependent on a travel direction of the train, and which of the vehicle doors is to be opened, and stops the train in accordance with the route information.

  • Patent number: 10829135
    Abstract: A method, an apparatus, a system, and a computer program product for managing safety for a railway system. A computer system generates a probability of a safety issue for a particular section of a railroad track in the railway system using information from a set of weather event sources. A set of unmanned aerial vehicles is dispatched to the particular section of the railroad track when the probability of the safety issue exceeds a threshold. A number of images of the particular section of the railroad track is received from the set of unmanned aerial vehicles. A risk score for the safety issue at the particular section of the railroad track is generated using the number of images by the computer system. An action is performed to resolve the safety issue using the risk score, enabling the computer system to manage safety issues for the railway system.
