Abstract:
The present invention concerns a method for reducing the drive delay of a rolling stock to reach a destination, the rolling stock being driven by a driver to follow a running profile that defines the speeds and positions of the rolling stock at different timings. The method comprises the steps of: -determining a current timing, -getting a nominal acceleration of the rolling stock, the nominal acceleration being determined by the driver of the rolling stock to follow the running profile at the current timing, -determining the speed error of the rolling stock with the rolling profile, -determining the position error of the rolling stock with the rolling profile, -determining an estimate of the time to reach the destination, -determining a marginal acceleration from the speed error, the position error and the estimated time to reach the destination, -accelerating the rolling stock with the sum of nominal and determined marginal accelerations.
Abstract:
Die Erfindung betrifft ein Verfahren zur Stabilisierung eines Schienenfahrzeugs (2) mit einem Radsatz (12) bei dem die Geschwindigkeit (84, 86, v) des Schienenfahrzeugs (2) bei Auftreten eines kritischen Schwingungszustands (KSZ) des Radsatzes (12) verändert wird. Ein vorteilhaftes Verfahren kann erreicht werden, wenn die Geschwindigkeit (84, 86, v) des Schienenfahrzeugs (2) unter Verwendung einer Schwingungszustandsgröße (66) des Radsatzes (12) verändert (110, 140) wird.

Abstract:
Navigating a transportation network by receiving an equipment identifier, querying a section of interest database to obtain at least one section of interest associated, accessing geolocation data from one or more geolocation sensors, querying a one section of interest using geolocation data to identify a next section of interest. With geolocation data, calculating at least one of a time to a next section of interest or a distance to a next section of interest, and determining that a reduction in speed is required, where a reduced speed is an amount of speed by which the speed must be reduced in order for the equipment to achieve a target speed associated with the next section of interest, and providing an alert configured to escalate to the user interface.
Abstract:
A machine learning system for maintaining distributed computer control systems for a train may include a data acquisition hub communicatively connected to a plurality of sensors configured to acquire real-time configuration data from one or more of the computer control systems. The machine learning system may also include an analytics server communicatively connected to the data acquisition hub. The analytics server may include a virtual system modeling engine configured to model an actual train control system comprising the distributed computer control systems, a virtual system model database configured to store one or more virtual system models of the distributed computer control systems, wherein each of the one or more virtual system models includes preset configuration settings for the distributed computer control systems, and a machine learning engine configured to monitor the real-time configuration data and the preset configuration settings. The machine learning engine may warn when there is a difference between the real-time configuration data and the preset configuration settings, the difference being indicative of at least two of the distributed computer control systems being out of synchronization by more than a threshold deviation.
