  • Publication number: 20220388555
    Abstract: The embodiments of the present application disclose an anti-collision method and apparatus for trains in a cooperative formation. The anti-collision method includes: determining whether it is necessary to control the current train to brake; determining whether a real-time distance between the current train and a previous adjacent train in the same formation as the current train is greater than a preset minimum safety distance; controlling, under a condition that the real-time distance is less than the preset minimum safety distance, the current train to perform electromagnetic braking; and calculating, under a condition that the real-time distance is greater than the preset minimum safety distance, a real-time safety distance between the current train and the previous adjacent train, and controlling, under a condition that the real-time distance is less than the real-time safety distance, the current train to brake.

  • Patent number: 10960909
    Abstract: The present invention provides an automatic train protection method, a vehicle on-board controller and a train based on vehicle-vehicle communication. The method includes: after a present train runs onto a main track, determining an OC with which the present train needs to establish communication; communicating, by the present train, with the OC to obtain train identifiers of all trains within the jurisdiction of the OC; respectively communicating, by the present train, with the train corresponding to each train identifier to obtain current running information of the train corresponding to each train identifier; identifying a front communication neighbor train of the present train; determining that no hidden train exists between the present train and the front communication neighbor train; and calculating current movement authority MA of the present train according to the current position information of the present train and of the front communication neighbor train.

  • Patent number: 10745038
    Abstract: An embodiment of the present disclosure provides a route resource controlling method, intelligent vehicle on-board controller and object controller. The method comprises: determining a route search extension distance of a train based on current location and speed of the train, wherein the current route search extension distance is the farthest distance in front of the train that is currently expected to be safe for operation based on current speed of the train; determining the currently required link and route resource contained thereof; determining the target authority of the route resource.

  • Patent number: 10297153
    Abstract: The present disclosure discloses a vehicle on-board controller centered train operation control system, the control system comprises intelligent vehicle controllers (IVOCs) provided on respective trains, the IVOC comprises a vehicle-vehicle communication device, an active identification device and a master control device. With such control system, rear-end train or more serious accidents may be avoided in case that there is a train without communication equipment or with equipment failure operation in front, or an obstruction impeding train operation appears in front of the train. Further, the control system provided by embodiments of the present disclosure enables a train to operate with a relatively high speed under the premise of safe operation, and improves operation efficiency and reliability.

  • Publication number: 20190111953
    Abstract: An urban rail transit train control system based on vehicle-vehicle communications, comprising an intelligent train supervision (ITS) system, a train manage center (TMC), a data communication system (DCS), and an intelligent vehicle on-board controller (IVOC) provided on each of trains, the ITS system. The TMC and the IVOC are communicatively coupled by the DCS, and IVOCs of the trains communicatively coupled by the DCS. IVOCs of all the trains report first train operation information to the ITS system and second train operation information to the TMC in accordance with a predetermined period. The TMC sends the received second train operation information to the ITS system. The ITS system determines a following train that needs a virtual coupling operation and a head train corresponding to the following train, and dispatch a virtual coupling operation instruction to the head train IVOC to perform a virtual coupling operation of trains.
