TRAIN CONTROL METHOD, APPARATUS, AND SYSTEM
A train control method is provided for a vehicle on-board controller (VOBC) configured on one end of a train. The method includes: performing a train awakening process; acquiring a running plan sent by an automatic train supervision (ATS) system after the train is successfully awakened; setting, according to a direction indicated by the running plan, a running direction of the train to be downward or upward; when the running direction is set to downward, using, as a head for train positioning, one end of the train not configured with the VOBC, to acquire positioning information of the train; when the running direction is set to upward, using, as the head for train positioning, one end of the train configured with the VOBC, to acquire the positioning information of the train; and controlling, according to the positioning information of the train, the train to pull out of a parking garage.
Control system enabling remote locomotive configuration setting
A control system for remotely configuring a locomotive includes a plurality of operational control devices located on-board the locomotive, the plurality of operational control devices being configured to implement a change to a designated configuration of the locomotive. A controller located on-board the locomotive is configured to activate the plurality of operational control devices to change the designated configuration of the locomotive upon receipt of a configuration command signal. An off-board remote user interface located remotely from the locomotive is configured to receive a single input from a user commanding a change in configuration of the locomotive, the single input being implemented by activation of a single input device on the remote user interface, and selectively send a configuration command signal to the on-board controller to activate the plurality of operational control devices to change the designated configuration of the locomotive.
SYSTEMS AND METHODS FOR ROUTE MAPPING
In one embodiment of the subject matter described herein a system is provided. The system includes a location determining circuit configured to acquire position information of a vehicle system moving along a route. The system includes a controller circuit having one or more processors. The controller circuit is configured to calculate curvatures of the route, based at least in part on the position information, to form a curvature waveform. The controller circuit is further configured to generate a route map based on the curvature waveform.
Method for controlling and possibly recovering the adhesion of the wheels of a controlled axle of a railway vehicle
A method for controlling and recovering the adhesion, during a slipping phase, of wheels (W.sub.i) belonging to at least two controlled axles (A.sub.i) of a railway vehicle, comprising the steps of: generating speed signals indicative of the angular speed (.sub.i) of said wheels (W.sub.i); estimating the value of the instantaneous adhesion ((T.sub.j)) at the point of contact of such wheels (W.sub.i) and the rails, using an adhesion observer; generating a target-slip value () for the wheels (W.sub.i) of the controlled axles (A.sub.i) by means of an optimization algorithm which processes the estimated adhesion values (.sub.i(T.sub.j)), and modifying the target-slip value continuously in time, with a predetermined sampling period, such as to maximize the average value of the adhesion of the wheels of the vehicle.
Methods and systems for decentralized rail signaling and positive train control
Systems and methods are provided for decentralized rail signaling and positive train control. A decentralized train control system may include a plurality of wayside units, configured for placement on or near tracks in a railway network, and one or more train-mounted units, each configured for use in a train operating in a railway network that support use of the decentralized train control system. Each train-mounted unit may configured to receive communicate with any wayside unit and/or train-mounted unit that comes within range, with the communicating including use of ultra-wideband (UWB) signals, and for generating control information based on the UWB signals, for use in controlling one or more functions associated with operation of the train.
PRESSURE SENSING PROBE
In one embodiment, a probe includes a first facet associated with a first pressure port operable to measure a first wind pressure, a second facet associated with a second pressure port operable to measure a second wind pressure, and a third facet associated with a third pressure port operable to measure a third wind pressure. The second facet is adjacent to the first facet and the third facet adjacent to the second facet. The probe further includes a fourth facet adjacent to the third facet and a fifth facet adjacent to the fourth facet and to the first facet. The first facet, the second facet, the third facet, the fourth facet, and the fifth facet are located between a first end portion and a second end portion of the probe.
SYSTEMS AND METHODS FOR MEASURING WIND VELOCITY FOR VEHICLES TRAVERSING A CURVE
In one embodiment, a method includes determining, by a controller, a first wind direction relative to a first vehicle and determining, by the controller, a first wind speed relative to the first vehicle. The method also includes calculating, by the controller, an absolute wind direction relative to ground using the first wind direction relative to the first vehicle and calculating, by the controller, an absolute wind speed relative to the ground using the first wind speed relative to the first vehicle. The method further includes calculating, by the controller, a second wind direction relative to a second vehicle using the absolute wind direction and calculating, by the controller, a second wind speed relative to the second vehicle using the absolute wind speed. A front end of the first vehicle and a front end of the second vehicle face different directions.
DETECTING AND OPTIMIZING THE STOPPING-POINT ACCURACY OF A VEHICLE
An apparatus for sensing and optimizing the stopping-point accuracy of a vehicle. The apparatus includes at least one sensor unit, which can be arranged on the vehicle, and at least one evaluation unit connected to the sensor unit. The at least one sensor unit is configured to measure a distance relative to a gap profile arranged at a stopping point to which the vehicle travels and to transmit the measurement result to the evaluation unit connected to the sensor unit. There is also described a corresponding system including the apparatus and the distance profile, and also a vehicle with such an apparatus.
SYSTEMS AND METHODS FOR DETERMINING WIND VELOCITY
In one embodiment, a system includes a vehicle, one or more probes coupled to the vehicle, and a controller. The vehicle is operable to traverse a distance. The one or more probes are operable to measure wind pressure and generate one or more wind pressure measurements. The controller is operable to receive the one or more wind pressure measurements from the one or more probes, determine a wind angle relative to the vehicle using the one or more wind pressure measurements, and determine a wind speed relative to the vehicle using the one or more wind pressure measurements and the wind angle.
Wireless train management system
A train control system comprising a track switch controller; RFID tags located at first and second track switches coupled via a length of track that store characteristics of train sets as they pass the track switches, and RFID tag readers located on the train sets, connected to a network. The train sets write data to the RFID tags such that the data is read by RFID tag readers of subsequent trains; and the data stored in the RFID tags is overwritten with new data each time a train set passes by the RFID tags.
