The present invention relates to the field of communications, and more particularly to methods and a system for providing high-speed communications on a high-speed railway. The technical result is a better quality communication channel provided by train-to-ground radio relay links The claimed system for providing high-speed communications on a high-speed railway comprises an internal and an external data exchange network. The internal network unites tail-end radio frequency modules mounted in the rear part of a train and equipped with narrow-band antennae, head-end radio frequency modules mounted in the front part of the train and equipped with narrow-band antennae, and switching equipment capable of processing signals from said modules and of providing network devices connected to said equipment with access to the external data exchange network. The external data exchange network unites base stations equipped with narrow-band antennae, said base stations being capable of establishing communication with the tail-end and head-end radio frequency modules in the train and being arranged in proximity to the railway clearance along the path of travel of the train. The antennae of the base stations and of the radio frequency modules in the train are configured to radiate radio waves in a short millimeter wave band.

A method and a system for transmitting enforceable instructions in a vehicle control (VC) system includes receiving, by a cyclic redundancy check (CRC) calculator, at least one enforceable instruction from vehicle systems. The CRC calculator calculates at least one enforceable instruction CRC based at least partly on the at least one enforceable instruction and transmits the at least one enforceable instruction CRC to a back office server of the VC system and/or an on-board system of a vehicle. Methods for cyclic redundancy check (CRC) hazard mitigation in a vehicle control (VC) system and verifying enforceable instruction data on-board a vehicle are also disclosed.

A positioning system and method for a monorail train are disclosed. The system includes: a first beacon, laid on one side of an up-going rail; a second beacon, laid on one side of a down-going rail, the first beacon and the second beacon being laid asymmetrically; a first beacon antenna and a second beacon antenna, the first beacon antenna being provided at a front carriage of the monorail train, the second beacon antenna being provided at a rear carriage of the monorail train, and the first beacon antenna and the second beacon antenna being provided on two opposite sides of the monorail train; and a positioning device, configured to acquire beacon data read by the first beacon antenna and beacon data read by the second beacon antenna and to determine a running direction and position information of the monorail train according to the beacon data read by the first beacon antenna and the beacon data read by the second beacon antenna.

A vehicle control system includes a controller that may receive location data points indicative of locations of a vehicle as measured by a location sensor. This controller may determine a distribution of the location data points and identify one or more of a route or a lane of a route in which the vehicle is disposed by comparing the distribution of the location data points to one or more characteristics of the one or more of the route or the lane of the route.

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.

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.

A data transmitting device includes: a transmitter; a processor; and a memory comprising instructions that, when executed by the processor, cause the processor to perform operations. The operations include: performing beam forming processing with a terminal provided in at least one moving object; detecting a beam angle based on a result of the beam forming processing; estimating a position of the at least one moving object based on the beam angle and installation position information of the data transmitting device; determining whether the estimated position of the at least one moving object is within a communication area of the data transmitting device; and transmitting desired data to the at least one moving object through the transmitter if it is determined to be within the communication area.

A system is provided that include at least one positioning system that can detect a location or position of a vehicle or a portion of a vehicle group that includes the vehicle, at least one sensor positioned on or associated with the vehicle that can generate sensor data of a determined parameter or condition, and a controller in communication with the sensor and the positioning system. The controller can determine that a hazard event has occurred based at least partially on sensor data, and can communicate a hazard event notification based at least in part on the location data and the sensor data to a remote server.

Systems and methods are provided for ultra-wideband (UWB) based rail line sensing and safety.

Systems for protecting a work train using an ultra-wideband (UWB) ranging system are disclosed. Aspects include a plurality of UWB wayside beacons disposed along a track, each of the plurality of UWB beacons configured to broadcast a unique beacon identification number. Aspects also include an onboard UWB control system disposed on a work train, the onboard UWB control system having a processing system in communication with radio-frequency communication device and an onboard UWB beacon. The onboard UWB beacon is configured to receive the unique beacon identification number from at least one of the plurality of UWB wayside beacons. The processing system is configured to determine a position of the work train on the track based upon known locations of the plurality of UWB wayside beacons, to transmit this position to a wayside Zone Controller, and to enforce a movement authority limit provided by the wayside zone controller.
