The present invention relates to a multi-layer coupling relationship-based train operation deviation propagation condition recognition method, where the method includes the following steps: (1) recognizing an effective train event time sequence, including an arrival event and a departure event of a train at each passing station; (2) uniformly extracting train activity data, including a stop activity, a section operation activity, a turn-back activity, and an arrival or departure interval activity; (3) constructing coupling relationship groups between a train event and a train activity and between train activities; and (4) performing statistics on changes of train operation deviation in each relationship group, and outputting a respective distribution function and a time-space distribution visualized result. Compared with the prior art, the present invention has the advantages of being practical, automatic recognition, feedback optimization, and the like.

The present invention discloses a method and system for protecting the operation of a train under an air pollution environment. The method for protecting the operation of the train under the air pollution environment comprises: acquiring multiple groups of roof and underbody air quality detection data; solving comprehensive roof and underbody air evaluation indicator Q.sub.0 and Q.sub.1 by using the experimental data; calculating an exposure time T.sub.0 of roof components and an exposure time T.sub.1 of underbody components; training a calculation model of pollutant condition about roof component and a calculation model of pollutant condition about underbody component; detecting roof and underbody air quality detection data after the train stops; calling the trained roof and calculation model of pollutant condition about underbody components, and solving roof and underbody component pollution levels, and performing corresponding cleaning on the roof and underbody components according to the solved roof and underbody component pollution levels. The present invention evaluates the exposed status of key components of the train under the air pollution environment, and takes relevant protective measures to ensure normal service lives of the key components of the train.

A vehicle running system based on rail transport, including a track, a framework, two levitation devices and a running device. The track is provided with a slot, in which the framework is provided. The levitation devices are provided between the track and the framework, and a top surface of the levitation device is fixedly connected to a bottom surface of the framework through a suspension structure. The running device includes two conductor plates and two running structures. The conductor plates are fixedly arranged on the inner wall of the slot, and are corresponding to the running structures. The reluctance force of magnetic wheels is converted into a driving force to drive maglev vehicles, and the levitation force is converted into a guiding force to realize the self-stabilization of vehicle guidance. A vehicle running method based on this system is also provided.

A vehicle control system includes a controller that communicates between a first vehicle and a second vehicle and/or a monitoring device in a vehicle system. The controller determines a communication loss and, responsive to determining the communication loss, switches to communicating via a different communication path. The controller also determines an operational restriction on movement of the vehicle system based on the communication loss that is determined, obtains a transitional plan that designates operational settings of the vehicle system at one or more different locations along a route being traveled by the vehicle system, different distances along the route being traveled by the vehicle system, and/or different times. The controller automatically changes the movement of the vehicle system according to the operational settings designated by the transitional plan to reduce the movement of the vehicle system to or below the operational restriction.

The following relates generally to system modeling. Some embodiments described herein learn a representation of the parameter feasibility space that make model parameter tuning easier by constraining the search space, thus enabling physical interpretation of the learned model. They also enable model-based system analytics (controls, diagnosis, prognostics) by providing a system model.

For fault detection in a switch system including multiple switches, for a respective switch its operating data are acquired and transmitted to a central control. For a respective first switch of the switch system, a deviation of an operating behavior of the first switch from a set behavior is determined by the central control on the basis of its operating data. If there is a deviation, operating data of the first switch are compared with operating data of other, second switches of the switch system and, depending on that, a second switch with similar operating data is selected.
