A RIO device mounted to a train includes an output unit that outputs a signal to a relay mounted to the train, and a controller that controls whether or not to cause the output unit to output the signal. The output unit includes a readback circuit that detects whether or not the signal is outputted from the output unit. The controller makes a signal stop request and a signal output request to the output unit before operation of the train starts, acquires a detection result of the readback circuit while each of the signal stop request and the signal output request is performed, and detects abnormality of the output unit using the detection result.

An SIL 4 over-speed protection device for a rail vehicle includes a first logical unit configured to be connected to a first power source, a first speed sensor and a first vital supervision circuit and a second logical unit configured to be connected to a second power source, a second speed sensor and a second vital supervision circuit. The first logical unit is configured to determine if the second logical unit is functioning properly and the second logical unit is configured to determine if the first logical unit is functioning properly.

According to some embodiments, a railcar monitoring system for monitoring one or more conditions associated with a railcar comprises a railcar controller and one or more sensors disposed throughout the railcar and communicably coupled to the railcar controller. The railcar controller is configured to exchange data with the one or more sensors and transmit data from the one or more sensors to a remote location. An amount of data exchanged between the railcar controller and the one or more sensors is controlled based on a railcar context. The railcar context is based on a location and/or activity associated with the railcar.

A train control system includes an onboard equipment with a wireless receiver and connected to a railway vehicle, a wayside equipment with a wireless transmitter and assigned to an interlocking entry point, wherein the interlocking entry point includes a home signal, wherein the wayside equipment is configured to wirelessly transmit status data of the home signal to the onboard equipment of the railway vehicle when approaching the interlocking entry point via a wireless communication link, and wherein the onboard equipment is configured to receive the status data of the home signal via the wireless communication link and to determine a distance between the railway vehicle and the interlocking entry point.

This system includes a ground ATC and an on board ATC, which is switched from an active mode toward a standby mode and vice versa by a wake-up unit. In the standby mode, only the following components remain powered: odometry device; a main computer; a radio communication device between the on board ATC and the ground ATC; the wake-up unit. The main computer is programmed so as, in the standby mode, to verify that the movement of the train measured by the odometry device from the switching from the active mode to the standby mode is zero and, in the affirmative, to send the ground ATC an instantaneous position of the train using the radio communication device.

A robust system processor comprising three parallel processors, each configured to process in parallel an input and emit an output; and a reconciler that compares the three outputs, determines whether at least two of the outputs are equal, and if so validates the majority output and communicates the validated output via a network to at least one other system processor.

An apparatus for supporting development of a program used in a control device of a train monitoring and controlling apparatus including a plurality of intra-train networks, the control device transmitting/receiving signals to/from the plurality of intra-train networks, the control device including a plurality of communication substrates for communicating with one of the plurality of intra-train networks and the control substrate connected to the plurality of communication substrates, the program development supporting apparatus receives a communication-substrate network communication data definition file used in each of the plurality of communication substrates, generates a control-substrate input/output signal variable definition file by using the communication-substrate network communication data definition file, and outputs the control-substrate input/output signal variable definition file. The control-substrate input/output signal variable definition file is used in the control substrate, the control substrate performing communication in a communication data format that is common among the plurality of communication substrates.

The preset disclosure provides a control system for operating one or more locomotives in a train, the control system including a first communication unit located on-board a first locomotive of a first consist in the train; and an off-board remote controller interface located remotely from the train, the off-board remote controller interface being configured to receive or generate a locomotive control command, store the received or generated locomotive control command in a shared ledger, and relay the locomotive control command to the first communication unit. The first communication unit is configured to receive the locomotive control command from the off-board remote controller interface.

Sensor systems and methods for measuring environmental parameters associated with a rail-bound vehicle having a plurality of carriages are disclosed. In an embodiment, the sensor system includes a plurality of sensors arranged in a separate carriage of the rail-bound vehicle at a defined distance from a reference point within the rail-bound vehicle. The sensor system further includes a control unit configured to receive measurement signals and time-shift the received measurement signals based on the defined distance and a velocity of the rail-bound vehicle to determine whether an event measured by the plurality of sensors is present at the same point in time in two or more signals of a modified (time-shifted) set of signals.

Systems and methods are provided for achieving vital ultra-wideband (UWB) based train control. Train-mounted units and wayside units that incorporate at least two separate and independent radios are used to obtain independent and separate ranging measurements in trains based on communications between the train-mounted units and wayside units. The communications includes communication of ultra-wideband (UWB) based signals.
