A train-information management device mounted on a train, includes: an intra-block position calculator to convert information on a kilometrage that indicates a position of the train into information on a block number and an intra-block position of a plurality of blocks into which a route of the train is divided and that are used when a train position is specified by a train radio system; and an on-board router to communicate the information on the block number and the intra-block position to a ground side by using a system that is different from a system that is used for communication between the ground side and a train side via a radio base station in the train radio system.

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.

The present invention includes an on-board control apparatus that generates train position information using ground coil position information and train speed information and outputs the train position information, and a ground control apparatus that receives the train position information outputted by the on-board control apparatus, identifies a position of a train using the train position information and stored track information, generates train control data having a size corresponding to the identified position of the train, and outputs the train control data toward the train.

The invention seeks to provide a communication system, a data transmitting device, a communication device, and a communication method capable of exchanging a sufficient capacity of data in a simple configuration without reducing the speed of a vehicle. The invention provides a communication system for transmitting data by a data transmitting device provided on a route of a moving body to the moving body having a plurality of vehicles in one formation; each of the plurality of vehicles being provided with a receiving unit that receives data transmitted from the data transmitting device; and the data transmitting device being configured to transmit mutually different data to the receiving units of the plurality of vehicles. The moving body may be a train such as the Shinkansen, or a transport vehicle such as a truck to which a plurality of cargo vehicles are connected.

The present disclosure relates to displacement measurements using magnetic displacement measurement units. In various embodiments, the disclosed displacement measurement unit is configured to determine a displacement position of a vehicle along a guideway. In various embodiments, the displacement measurement unit includes a set of locator devices that are distributed at fixed displacement positions along the guideway, where a given locator device includes a magnetic element configured to produce a corresponding magnetic field. Further, in various embodiments, the displacement measurement unit includes a position sensor that is attached to the vehicle, where the position sensor is configured to detect a magnetic field produced one or more of the locator devices when the position sensor is brought within a detection range of one or more locator devices.

Embodiments of the present disclosure provide a method for waking up a train which in four carriages coupling mode from sleep state on double-track-line, a system, an electronic apparatus, and a computer-readable storage medium. The method comprises steps of: receiving a static test request transmitted by a train in four carriages coupling mode on the track B1 or the track B2, determining whether a test environment of the train satisfies a static test condition, and transmitting a static test permission instruction to the train; receiving a dynamic test request transmitted by the train, determining whether a test environment of the train satisfies a dynamic test condition, and transmitting a dynamic test permission instruction to the train; and receiving information, indicating that the train can be woken up, transmitted by the train, and controlling the train to wake up from sleep state.

A method operates a track-bound traffic system which carries out a determination that a first track section part lying between a track-bound vehicle and a second track section is free of vehicles. A track-side device disposed in a first track section at a distance to an adjacent second track section, transmits status information which characterizes the second track section as being free of track-bound vehicles, and the transmitted status information is received by a vehicle traversing the first track section. The distance is measured such that no other track-bound vehicle fits in a first track section part lying between the track-bound vehicle and the second track section when the track-bound vehicle receives the status information, and the first track section part lying between the track-bound vehicle and the second track section is identified as being free of other track-bound vehicles by the track-bound vehicle based on the received status information.

Apparatuses, systems, methods, and software for train control and tracking using multi sensors, SSD/QR signs, and/or RF reflectors are disclosed, which enable determination of train location on a guideway, train movement authority, train length, and coupler status of each vehicle (married pair) and the consist (integrity) of the train.

Systems and methods are provided for train operation control and enforcement. A vehicle mounted system for train control may include a vehicle mounted data radio mounted on a railway vehicle and a vehicle mounted controller. The vehicle mounted controller may be connected to the vehicle mounted data radio. The vehicle mounted data radio may be in wireless communication with a wayside reporting station, which may be in communication with a signal control point that is associated with a safety point that is further associated with an interlocking, and the vehicle mounted data radio may be configured to receive signal state status information from the wayside reporting station. The vehicle mounted controller may be configured to determine a distance between the railway vehicle and the safety point. The vehicle mounted data radio may be an ultra-wide band (UWB) radio.

A railroad communication system includes a radio transmitter for generating radio communications signals and a length of railroad rail coupled to the radio transmitter. The length of rail is disposed on a set of nonconductive railroad ties to form a transmission line for radiating the radio communications signals to a radio receiver in a vicinity of the length of railroad rail.
