According to one aspect of the present disclosure, a system for controlling a locomotive may comprise a controller; an Ethernet switch; one or more Ethernet modules in communication with the controller through the Ethernet switch, wherein a given Ethernet module of the one or more Ethernet modules includes a microcontroller and one or more connectors, wherein the microcontroller provides one or more communication interfaces; one or more power supplies connected to the one or more Ethernet modules and providing power to the one or more Ethernet modules; and one or more locomotive units in communication with the one or more Ethernet modules, wherein the one or more locomotive units are installed on the locomotive and controlled by the controller.

A method establishes a vehicle area network on a vehicle having a tractor with a tractor wireless hub, the tractor being connected to a first trailer having a first trailer wireless hub. The method activates the tractor hub and the first trailer wireless hub, and shares credentials between the tractor wireless hub and the first trailer wireless hub in accordance with out of band pairing techniques. Typically, the tractor wireless hub acts as an access point for the vehicle area network but the access point can be centralized by: searching down a length of the vehicle to determine relative locations of the tractor wireless hub, the first trailer wireless hub and the second trailer wireless hub; determining a centrally located hub based on the locations; and establishing the centrally located hub as the access point.

A door controller with an integrated data collection and transmission device, which comprises a motor driving module, a bus communication module, a vehicle door opening/closing control module, a parameter control module, and a data collection and transmission device. The data collection and transmission device is configured to receive and process four types of data collected by a motor driving data collection unit, a vehicle door opening/closing control data collection unit, an operation parameter collection unit, and a bus communication data collection unit, and transmit the four types of processed data to a background server.

A device configured to process data comprised in data messages passing on message buses of a rolling stock comprises: a universal input interface receiving data messages complying with the three following physical layers: RS232; RS485; CAN. From the message buses, the data messages comprise data; a processing engine receiving a remote requested configuration comprising one or more processing rules; a standardizing unit decoding the data messages into standardized data streams in function of the remote requested configuration; and wherein the processing engine further applies one or more of the one or more processing rules of the standardized data streams in function of the remote requested configuration.

A system for the supraregional operation of a vehicle includes at least one control device. A first vehicle bus can be connected to the control device, wherein a defined number of first control apparatuses can be connected to the first vehicle bus; and a second vehicle bus can be connected to the control device, wherein a defined number of second control apparatuses can be connected to the second vehicle bus. The control device provides for a defined minimum functionality during a moving transition of the vehicle from a defined first region into a defined second region. The control device changes a functionality for the second control apparatuses during the moving transition from the first region into the second region, and the control device is configured to control the coordination of the changing of the functionality of the second control apparatuses.

First terminals are usable as input terminals or output terminals and second terminals are usable as input terminals. A switching unit switches the first terminals between input and output, based on an instruction indicating the number of first terminals to be used as output terminals. If at least one first terminal is used as an output terminal, a first signal is output to the first terminals used as output terminals. A storage unit (stores second and third signal values, the second signal value being a value of a second signal input from the input terminal, the third signal value being a value obtained by arraying a plurality of the second signal values based on the value of the first signal. A setting unit reads the second signal value or the third signal value based on the instruction signal, and acquires information on the value of the second signal input.

A train compartment brake control method comprises the following steps: acquiring the number of train compartments of a current train; acquiring the number and type of a current train compartment; and on the basis of a train brake instruction and the number of train compartments of the current train, calculating a braking force of the current train compartment, and performing brake control on the current train compartment. The technical solution described in the present application is applicable to a train having any number of train compartments. The above method acquires the number of train compartments of a train in real time, calculates the braking force required by each train compartment according to the number and type of a current train compartment, and performs brake control on the train. The method ensures normal operation of brake control for a train having any number of train compartments and ensures that the brake control is not effected by an adjustment to the order or the number of train compartments. In the above technical solution, brake control units (BCUs) of each train are no longer distinguished as a primary BCU or a secondary BCU. The BCUs of each train are at the same control level and are redundant to each other, so as to reduce the use of a BCU of a single train compartment, thereby reducing operating costs.

The present disclosure discloses a CANopen-based train network data transmission method. The method includes: monitoring, on an active network, a heartbeat packet transmitted through a first CAN channel by each slave node related to an active master node; determining whether the first CAN channel of each slave node is faulty; transmitting a reset instruction to a first node from the active network if no heartbeat packet of the first node is received within the preset first heartbeat period; learning, if no heartbeat packet of the first node is received, that the first CAN channel of the first node is faulty, and switching to a standby network to monitor the heartbeat packet transmitted by the first node; otherwise, receiving, on the standby network, data transmitted by the first node, and also receiving, on the active network, data transmitted by other slave nodes that normally transmit heartbeat packets.

A system is provided having a vehicle. The vehicle includes a chassis, and a first network bus extending from internally in the chassis to a first network port attached externally to the chassis at a first side of the vehicle. The vehicle includes a second network bus extending from internally in the chassis to a second network port attached externally to the first chassis at a second side of the vehicle. The first network bus has a first electrical configuration and the second network bus has a second electrical configuration that is different than the first electrical configuration.
