Abstract:
A system and method for generating a trip plan for a vehicle system determine a first trip plan for a trip of a vehicle system from a first location to a second location over a first route that includes a first intersection with a second route. The first trip plan designates operational settings of the vehicle system. An alternate trip plan that extends along the second route from the first intersection to the second location of the trip of the vehicle system also is determined. The first and alternate trip plans are determined prior to the vehicle system reaching the first intersection. Movement of the vehicle system is controlled according to the first trip plan prior to the vehicle system reaching the first intersection and then controlled according to the alternate trip plan responsive to the vehicle system deviating from the first trip plan.
Abstract:
A method includes, responsive to a determination that a first vehicle system to be received in a vehicle yard is longer than a length of a receiving route of the vehicle yard that is designated for receiving the first vehicle system, processing a first movement plan to generate a revised movement plan. The first movement plan governs movement of the first vehicle system and one or more second vehicle systems in a transportation network that includes the vehicle yard. The revised movement plan is generated based at least in part on a designated time restriction for the first vehicle system to travel to and be received within the vehicle yard on the receiving route. The method also includes controlling at least one of the first vehicle system or at least one of the one or more second vehicle systems based on the revised movement plan.
Abstract:
A communication device includes an analog connector onboard a vehicle in a vehicle system that is coupled with a multiple unit (MU) cable extending through the vehicle system for communication of analog control signals. The device includes a network connector disposed onboard the first vehicle to communicatively couple with a digital communication network of the vehicle system that is separate from the MU cable. The device also includes a relay to close and conductively couple the control system of the first vehicle with the MU cable and to open to decouple a portion of the MU cable disposed onboard the first vehicle with a remainder of the MU cable that is off-board the first vehicle.
Abstract:
Methods and systems relate to establishing a communication link with a wayside device, determining whether or not to at least one of update or configure the wayside device in dependence upon at least one update parameter, and when it is determined to update or configure the wayside device, updating or configuring the wayside device from a remote location.
Abstract:
Systems are provided to determine a location of an electrical fault in an electrical system of a vehicle. A test apparatus can include a control unit and a plurality of scan circuits. The control unit is configured to electrically couple the plurality of scan circuits to the electrical system and trigger the plurality of scan circuits to pass electrical signals to the electrical system. Each scan circuit is configured to detect a presence of an electrical fault in the electrical system based on an electrical signal passed. Each scan circuit provides information indicative of a location of the electrical fault in the electrical system, when detected, to the control unit.
Abstract:
A method for de-rating propulsion-generating vehicles in a vehicle system includes identifying a feature of interest in a route and identifying one or more propulsion-generating vehicles as de-rating vehicles that are subject to a handling rule associated with the feature of interest. The handling rule dictates that throttle settings be limited to a reduced range when traveling over the feature of interest. The method further includes, when the de-rating vehicles are traveling along the route and outside of the feature of interest, operating the de-rating vehicles using a larger range of throttle settings and, responsive to approaching and/or traveling over the feature of interest, automatically de-rating at least a subset of the propulsion-generating vehicles in the vehicle system by operating the at least a subset of the propulsion-generating vehicles using the smaller range of throttle settings during travel over the feature of interest.
Abstract:
A route examining system includes an application device, a control unit, a detection unit, and an identification unit. The application device is onboard a first vehicle of a first vehicle system traveling along a route. The control unit controls supply of electric current from a power source to the application device in order to electrically inject an examination signal into the route via the application device. The detection unit is off-board of the first vehicle and monitors electrical characteristics of the route in response to the examination signal being injected into the route. The identification unit is off-board of the first vehicle and examines the one or more electrical characteristics of the route in order to determine whether a section of the route extending between the first vehicle and the detection unit is potentially damaged based on the one or more electrical characteristics.
Abstract:
A sensing system includes a leading sensor, a trailing sensor, and a route examining unit. The leading sensor is onboard a first vehicle of a vehicle system that is traveling along a route. The leading sensor measures first characteristics of the route as the vehicle system moves along the route. The trailing sensor is disposed onboard a second vehicle of the vehicle system. The trailing sensor measures second characteristics of the route as the vehicle system moves along the route. The route examining unit is disposed onboard the vehicle system and receives the first characteristics of the route and the second characteristics of the route to compare the first characteristics with the second characteristics. The route examining unit also identifies a segment of the route as being damaged based on a comparison of the first characteristics with the second characteristics.
Abstract:
A method includes operating a vehicle traveling in a transportation network with a throttle of the vehicle at a maximum throttle setting during a trip of the vehicle along a route from a first location to a different, second location. The method also includes applying a dynamic brake of the vehicle at a maximum brake setting of the dynamic brake, and alternating between operating the vehicle with the throttle at the maximum throttle setting and applying the dynamic brake of the vehicle at the maximum brake setting along a route being traveled by the vehicle from the first location to the second location.
Abstract:
A method for determining a slack condition of a vehicle system includes determining when each of first and second vehicles reaches a designated location along a route. The method also includes communicating a response message from the second vehicle to the first vehicle responsive to the second vehicle reaching the designated location, calculating a separation distance between the first vehicle and the second vehicle based on a time delay between a first time when the first vehicle reached the designated location and a second time when the second vehicle reached the designated location, and determining a slack condition of the vehicle system based on the separation distance. The slack condition is representative of an amount of slack in the vehicle system between the first and second vehicles.
