摘要： The disclosure relates to a light train control system applied to oversea freight railways. The system integrates automatic block, station turnout control and train operation overspeed protection control and comprises an on-board subsystem, an RBC subsystem and a satellite positioning differential base station management subsystem, wherein the on-board subsystem is respectively connected to the RBC subsystem and the satellite positioning differential base station management subsystem. The light train control system adopts two-way continuous train-ground wireless communication and uses on-board signals as main signals of train operation to control the train operation; meanwhile, the system monitors the train operation, so as to provide an alarm to a driver when the situation changes, and to brake a train when necessary; and the system uses an electronic map to manage line data of a whole line, achieves dynamic configuration of the transport capacity by means of a virtual block technology, and remotely controls basic signaling equipment by means of an RBC. Compared with the prior art, the disclosure has the advantages of efficient system operation and simplified trackside equipment.

摘要： A switch control method and apparatus, and a storage medium are provided, which relate to the field of urban rail transit technologies. The method includes: in a process that a train requests a target object for a switch resource, determining that the train is a train before and nearest a switch in combination with switch information sent from an object controller; when the switch is in an idle state, requesting the object controller to move the switch if it is determined that a current switch orientation of the switch is inconsistent with a switch orientation required by the train for the switch, so that the object controller controls to move the switch, and adjusts a status of the switch to a locked state after the switch is moved; and controlling the train to pass through the switch according to a response message returned by the object controller.

摘要： A system and method for virtual block stick circuits is presented. The present disclosure implements specialized algorithms adapted to determine the true status of a virtual block based on multiple inputs from different perspectives. In one embodiment, the system can use the far house perspective of that virtual track segment and the PTC hazard for the near virtual track segment directly adjacent to the near house uses the near house perspective of that virtual track segment. For the middle virtual track segments, the near house perspectives of the middle virtual track segments are held ‘TRUE’ if they are already ‘TRUE’ when the train first enters the block, using stick circuits for the near house perspective of the middle track circuits. The vital application can then indicate the true state of the virtual track segment as occupied (FALSE), to protect the train from trains that follow.

摘要： A method of railroad track control includes partitioning a physical track block into a plurality of virtual track blocks, the physical track block defined by first and second insulated joints disposed at corresponding first and second ends of a length of railroad track. The presence of an electrical circuit discontinuity in one of the plurality of virtual track blocks; is detected and in response a corresponding virtual track block position code indicating the presence of the discontinuity in the one of the plurality of virtual track blocks is generated.

摘要： An independent cart system with safety functions that prevent unintended motion independently within different sections of the track while permitting motion along other sections of the track is disclosed. A safety controller receives one or more input signals corresponding to operating conditions along the track. A safety program executing in the safety controller monitors the state of the input signals to determine whether a safety function is to be executed. When a safety program is executed, the safety controller transmits an output signal to one or more segment controllers present in one section along the track. Each segment controller is responsible for regulating current flow to the coils mounted to the corresponding track segment. In response to the signal from the safety controller, each segment controller in the section controls the power output to the coils along that section of track to achieve the safe operation desired in that segment.

摘要： A train control apparatus includes a setting reception unit that receives setting information regarding a temporary speed limit section and a speed limit. A control unit generates temporary speed limit information for the trains. A communication unit transmits the temporary speed limit information to the trains. If information regarding all temporary speed limit sections cannot be included in the temporary speed limit information, the control unit includes, in the temporary speed limit information, information regarding a specified number of temporary speed limit sections located on a traveling direction side, and changes a speed limit in one or more temporary speed limit sections included in the temporary speed limit information on the basis of a speed limit set in a temporary speed limit section that is adjacent to a temporary speed limit section included in the temporary speed limit information, and is not included in the temporary speed limit information.
