The present disclosure relates to a passenger communication output control circuit for an unmanned metro train. The unmanned metro train is installed with passenger emergency communication units each having a communication button and a communication relay. The communication relay has a normally-closed contact pair and is linked with the communication button in a one-to-one correspondence. When the communication button is pushed down, the communication relay is energized to disconnect the normally-closed contact pair. The normally-closed contact pairs of all the coaches are connected in series to form an emergency communication circuit. Two terminals of the emergency communication circuit are respectively connected to a train power supply and an input/output module of a TCMS in the coach. When the passenger information system works normally, both a communication network and hardwire can transmit the communication signal. When the two communication signals are inconsistent, the communication signal transmitted by hardwire shall prevail.

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 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.

A transmission system includes: a hub to receive a control command from two or more controllers that control operation of an in-vehicle machinery installed in a train, and to control an output of the control command on the basis of a priority assigned to the control command, and a system-controller to determine an operating state of a controller that is a source of the control command, the system-controller being capable of changing a priority assigned to a control command transmitted from a controller whose operating state has been determined, on the basis of a determination result.

A CANopen-based train network data transmission method includes: switching, when a first CAN channel of a first slave node is detected as faulty, to a second CAN channel of the first slave node to receive over a standby network a heartbeat packet and data transmitted by another relevant node; monitoring, if no heartbeat packet transmitted by a relevant second slave node is received from the standby network within a preset heartbeat period, by an active master node, in an active network, a heartbeat packet and data transmitted by the second slave node; receiving, through the second CAN channel, the heartbeat packet and the data of the second slave node forwarded by the active master node to the standby network when the active master node detects in the active network the heartbeat packet and the data transmitted by the second slave node through the first CAN channel.

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.

Method and system for communicating data between a transmitter and a receiver via a physical transmission medium interposed there between, wherein the transmitter outputs over the transmission medium towards the receiver, a predefined precursor signal followed by a target signal carrying data packet. Based on the precursor signal received at the receiver, estimated values of actual electrical parameters of the physical transmission medium are computed via a predetermined model of the physical transmission medium, wherein the computed estimated values of the electrical parameters are indicative of a distortion caused by the physical transmission medium on the predefined precursor signal outputted by the transmitter. The data packets originally outputted by the transmitter are estimated based on the computed estimated values of the actual electrical parameters and on the target signal received at the receiver.

An automation system, an operating method for an automation system, and a computer program product enable communication between assemblies of an automation system connected to each other via a back panel bus, wherein the assemblies can exchange data with each other directly, without sending the data via a master.

Systems and methods for reconfigurable on-vehicle data routing are provided. In one embodiment, a data link communication system comprises: a router to communicate with at least one communication bus and at least one data bus, and monitor data communicated over the communication data buses, wherein the communication bus communicates data link messages with an off-vehicle service provider system, wherein the data bus transports data between the router and a plurality of on-vehicle systems; a routing control logic; and a conditional logic database, wherein the database comprises definitions of one or more datatypes and definitions for at least one data forwarding command; wherein, in response to receiving a first set of data associated with a datatype defined by the database, the logic executes the at least one data forwarding command to control the router to output a second set of data to one or more of the plurality of on-vehicle systems.
