Abstract:
A system and method for examining a route and/or vehicle system obtain a route parameter and/or a vehicle parameter from discrete examinations of the route and/or the vehicle system. The route parameter is indicative of a health of the route over which the vehicle system travels. The vehicle parameter is indicative of a health of the vehicle system. The discrete examinations of the route and/or the vehicle system are separated from each other by location and/or time. The route parameter and/or the vehicle parameter are examined to determine whether the route and/or the vehicle system is damaged and, responsive to determining that the route and/or the vehicle is damaged, the route and/or the vehicle system are continually monitored, such as by examination equipment onboard the vehicle system.
Abstract:
A system includes a router transceiver unit that is configured to be disposed on-board a vehicle system. The vehicle system may have at least a source vehicle and a separate linked vehicle that are communicatively linked with each other through a system network of the vehicle system. The router transceiver unit is configured to be communicatively coupled to a requesting operational component of the source vehicle and the system network. The router transceiver unit is also configured to receive a local data packet from the requesting operational component that is directed toward a target operational component of the linked vehicle. The router transceiver unit includes an encapsulation module that is configured to transform the local data packet into an in-tunnel data packet, wherein the local and in-tunnel data packets have different packet formats.
Abstract:
A method for controllably linking propulsion units in a vehicle consist includes transmitting a linking signal having an identity of a lead propulsion unit. A remote propulsion unit is remotely controlled by the lead unit when the identity matches a designated identity stored onboard the remote unit. A de-linking signal is transmitted from the lead unit when the lead unit is to be decoupled from the vehicle consist. The de-linking signal includes a replacement identity of a replacement propulsion unit. A replacement linking signal is transmitted from a second lead unit. The remote propulsion unit allows the second lead propulsion unit to remotely control the operations of the remote propulsion unit when replacement identity stored onboard the remote propulsion unit matches an identity that is communicated in the replacement linking signal.
Abstract:
A method and system for examining velocity differences in a vehicle speed of a vehicle and the angular speed of the axles and/or wheels of the vehicle system traveling along a route to determine if the route is damaged and/or to identify the location of the potentially damaged section of the route. The differences may represent wheel creeps of the vehicle system.
Abstract:
In a system and method for communicating data in a locomotive consist or other vehicle consist (comprising at least first and second linked vehicles), a first electronic component in the first vehicle of the vehicle consist is monitored to determine if the component is in (or enters) a failure state. In the failure state, the first electronic component is unable to perform a designated function. Upon determining the failure state, data is transmitted from the first vehicle to a second electronic component on the second vehicle, over a communication channel linking the first vehicle and the second vehicle. The second electronic component is operated based on the transmitted data, with the second electronic component performing the designated function that the first electronic component is unable to perform.
Abstract:
A method includes monitoring an available amount of electrical energy on an electrical power grid for powering one or more loads at one time. The available amount of electrical energy represents an amount of electrical energy that may be consumed at one time without exceeding a grid capacity. The method also includes monitoring an electrical energy demand of plural electric vehicles traveling on a network of routes that includes one or more conductive pathways extending along the routes for delivering the electrical energy from the electrical power grid to the electric vehicles. The method further includes controlling movements of the electric vehicles such that the electrical energy demand of the electric vehicles does not exceed the available amount of electrical energy on the electrical power grid.
Abstract:
A system includes a router transceiver unit that is configured to be disposed on-board a vehicle system. The vehicle system may have at least a source vehicle and a separate linked vehicle that are mechanically linked with each other to travel together along a route and that are communicatively linked with each other through a system network of the vehicle system. The router transceiver unit is configured to be communicatively coupled to a requesting operational component of the source vehicle and the system network. The router transceiver unit is also configured to receive a local data packet from the requesting operational component that is directed toward a target operational component of the linked vehicle. The router transceiver unit includes an encapsulation module that is configured to transform the local data packet into an in-tunnel data packet, where the local and in-tunnel data packets have different packet formats.
Abstract:
System including an effort-monitoring system configured to control tractive efforts (TEs) individually produced by propulsion-generating vehicles in a vehicle system. The effort-monitoring system is configured to control each of the propulsion-generating vehicles to provide a respective prescribed TE. The vehicle system operates at a system TE when each of the propulsion-generating vehicles is providing the respective prescribed TE. The prescribed TEs are determined by at least one of an operating plan of the vehicle system or a regulation that limits TE or ground speed of the vehicle system. In response to determining that a first propulsion-generating vehicle is providing a reduced TE that is less than the prescribed TE of the first propulsion-generating vehicle, the effort-monitoring system is configured to control a second propulsion-generating vehicle to exceed the prescribed TE of the second propulsion-generating vehicle so that the vehicle system is operating at or below the system TE.
Abstract:
A system includes an application device, a control unit, a detection unit, an identification unit, and a secondary analysis module. The application device is configured to be at least one of conductively or inductively coupled with a route. The control unit is configured to control supply of electric current to inject an examination signal into the route via the application device. The detection unit is configured to monitor one or more electrical characteristics of the route. The identification unit is configured to examine the one or more electrical characteristics of the route to determine whether a section of the route is potentially damaged. The secondary analysis module is configured to perform a secondary analysis of the potentially damaged section of the route to at least one of confirm that damage has occurred, identify a type of damage, or assess a level of damage.
