Abstract:
The disclosure is directed to a communication method for use with a train consist having a locomotive and a tender car. The communication method may include transmitting between the locomotive and the tender car operational data captured by network components located onboard at least one of the locomotive and the tender car. The method may further include selectively adjusting an operation of at least one of the locomotive and the tender car based on the data.
Abstract:
A method performed by a first rolling stock, comprising: receiving one or more communications from one or more second rolling stock, with a railroad network comprising the first rolling stock and the one or more second rolling stock; executing, by the first rolling stock, one or more of a local rule and a global rule; determining, based on executing, a speed for the first rolling stock relative to a speed of at least one of the one or more second rolling stock; and controlling the speed for the first rolling stock in accordance with the determined speed, wherein controlling promotes avoidance of a collision between the first rolling stock and the at least one of the one or more second rolling stock.
Abstract:
A positive train control may comprise a plurality of different sensors coupled to a processor that determines whether there is an object on a track way and/or an anomaly of a track way, and if there is, provides an alert and/or a train control action. The plural sensors may include a visual imager, an infrared imager, a radar, a doppler radar, a laser sensor, a laser ranging device, an acoustic sensor, and/or an acoustic ranging device. Data from the plural sensors is geo-tagged and time tagged. Some embodiments of the train control employ track monitors, switch monitors and/or wayside monitors, and some employ locating devices such as GPS and inertial devices.
Abstract:
A method and a structure for an Autonomous Train Control System (ATCS) are disclosed, and are based on a plurality of autonomous train control elements that operate independent of each other. An autonomous train control element operates within an allocated track space, and based on predefined rules. Further, autonomous train control elements are paired together to exchange operational data. Pursuant to the predefined rules, an autonomous train control element acquires needed track space from a paired element, and relinquishes track space that is not required for its autonomous operation to a paired element. Further, an autonomous train control element is assigned a priority level with respect to the acquisition/relinquishment of track space.
Abstract:
A ground device 6 includes a control unit 15, a storage unit 16, and a ground transmitting and receiving unit 17. A ground antenna 18 is connected to the ground transmitting and receiving unit 17. Train information from an on-board device 11 is received by the ground transmitting and receiving unit 16 via the ground antenna 18, and is then transmitted to the control unit 15. Meanwhile, information from the control unit 15 is transmitted to the on-board device 11 via the ground transmitting and receiving unit 17 and the on-board antenna 18. The control unit 15 accumulates the train information on a train 4 in the storage unit 16, and also transmits, to the on-board device 11, command information for a device installed in the train 4.
Abstract:
An embodiment includes: a speed limit setter that acquires a speed limit section of a running section delimited at positions at which a speed limit changes; a reverse coasting curve generator that determines a base point based on a terminal position of the speed limit section and an upper limit speed according to a speed limit for the speed limit section and generates a reverse coasting curve from the base point based on vehicle performance information and route information; a parameter setter that determines a coasting start position based on the reverse coasting curve; and a simulator that generates a running profile by performing a running simulation based on the running section, speed limit information on the running section, the reverse coasting curve, the coasting start position, and the vehicle performance information and the route information. The reverse coasting curve generator sets a range below the upper limit speed as a coasting range and sets a range equal to or above the upper limit speed to the upper limit speed during coasting from the base point toward a departure point.

Abstract:
Systems and methods for braking or launching a ride vehicle are provided. In one embodiment, a system includes a linear induction motor (LIM) installed in a curved portion of a track, a ride vehicle disposed upon the track, one or more reaction plates coupled to a side of the ride vehicle facing the track via a plurality of actuators, one or more sensors configured to monitor an air gap between the one or more reaction plates and the LIM, and a processor configured to determine which of the plurality of actuators to actuate and a desired performance of each of the plurality of actuators based on data received from the one or more sensors to maintain the air gap at a desired level throughout traversal of the curve by the ride vehicle.
Abstract:
An interlocking device performs route control for trains based on: first operation diagram information as train operation diagram information on a train which runs between stations; second operation diagram information as train operation diagram information on a train which moves in a station yard; and on-track position information on the trains. The interlocking device performs control with time on a signal and/or a switch on a route of a train based on different information according to whether a predetermined condition is satisfied.
