  • Patent number: 12168467
    Abstract: A method for energy-optimized operation of a rail vehicle fleet. The fleet includes n rail vehicles, each with a state-influencing system for influencing a vehicle state to generate and/or consume electrical energy and a computer unit trained by machine learning. For every i of 1 to n during operation of the rail vehicle fleet an action to be applied to the state-influencing system of the i-th rail vehicle is selected by the computer unit of the i-th rail vehicle while taking into account at least one target criterion for the i-th rail vehicle and according to vehicle, location, and/or route-related status parameters. The action, when applied to the state-influencing system of the i-th rail vehicle, contributes to the optimization of an electrical total energy balance of the state-influencing systems of the rail vehicle fleet, and the selected action is applied to the state-influencing system of the i-th rail vehicle.

    Abstract: An antenna arrangement for the mobile communication of a rail vehicle and a rail vehicle with an antenna arrangement of the type. The antenna arrangement has at least two transmitting antennas and at least two receiving antennas. The transmitting antennas are spatially grouped in a transmitting group and the receiving antennas are spatially grouped in a receiving group. The distances between the transmitting antennas and between the receiving antennas is smaller than the overall distance between the transmitting group and the receiving group. The antennas can thereby be arranged in a much more space-saving fashion on the vehicles because large distances have to be provided only between the groups, not between the antennas within the groups. Where the space needed is low, interference-free operation of the antennas is thus advantageously possible.

  • Patent number: 12005944
    Abstract: For diagnosing a railroad switch with a point machine, a first and a second time series of a sensor signal of the point machine are received. Moreover, changes in the first and the second time series are detected indicating changes of operational conditions of the point machine. Furthermore, an event point of a respective change in the first and in the second time series is allocated to a respective component of the railroad switch or of the point machine based on a simulation modelling the respective component. Then for a respective component: event points allocated to that respective component are identified, the sensor signal at a first identified event point in the first time series is compared with the sensor signal at a second identified event point in the second time series, and depending on the comparison a component-specific fault information and an identification of the respective component are output.

  • Patent number: 11999398
    Abstract: A method of installing/verifying positive train control components begins by entering component details into a data entry screen (e.g., a component type; serial number; name of the installer; train line name; a location description). A rough installation location is determined, and the component is installed. A GPS receiver determines the exact location of the installed component, which is entered with the component details. Photographs of the installed component are attached thereto. An installation icon for the installed component is overlaid on a digital map at the determined GPS location. Toggling the installation icon causes displaying of the data. An inspector physically verifies the entered details and GPS location of the installed component using a verification screen, and a third-party GPS receiver. When the two GPS obtained positions are within a threshold amount, and the details are correct, the inspector toggles a radio button confirming the data, which is otherwise corrected.

  • Patent number: 11999267
    Abstract: A power line system is provided for efficiently using excess electrical energy produced by electric vehicles in a generation mode. A power line detector on the vehicle senses the power line to determine if voltage ripples are present before supplying excess electrical energy from the vehicle to the power line. First voltage ripples are generated on the line by a substation providing power to the power line. Second voltage ripples are also generated on the power line by a ripple generator to allow excess energy from the vehicle to be supplied to the power line in order to charge an energy storage system.

  • Patent number: 11958515
    Abstract: A method for identifying properties of rail-guided vehicles uses an axle counter to detect vehicle measurement data as the vehicle crosses. The measurement data are analyzed in a computer and speed and distances between vehicle axles are ascertained. A property of the vehicle is ascertained in a computer based on the ascertained speed and distances between axles. A checking step ascertains a pattern of normal distances between axles in that a normal distance between axles calculated by considering a predefined normal speed is assigned to each ascertained distance between axles, and by considering their order, the normal distances between axles merge to form the pattern. The pattern is compared with reference patterns, and upon identified conformity of the pattern and reference pattern, a type linked to the reference pattern is assigned to the vehicle as a property. An apparatus and computer program determining properties of vehicles are also provided.
