Definitions

  • the present invention relates to train interval protection of a CBTC system, and in particular to a CBTC system based on interval protection and heterogeneous redundancy and an implementation method.
  • interval protection is an important function to ensure safe train running. To ensure the safe train running, intervals should be kept between trains running on a same line, and the intervals usually depend on speeds, braking distances, safe protection distances, and other factors of the trains.
  • block a manner in which only one train is allowed to run is called block, which mainly includes fixed block, moving block, and quasi-moving block.
  • An existing CBTC system performs train interval protection based on active positioning and a principle of the moving block.
  • the system causes a train to be out of position in the case of train skidding, instantaneous loss of a switch position, or the like.
  • a trackside area controller cannot obtain position information of the train out of position, so that the train out of position cannot continue to run in ATP mode, which affects running of a subsequent train, resulting in a significant reduction in running efficiency of a whole line.
  • a multi-mode train control solution using BM+CBTC or TBTC+CBTC is used for resolving the problem.
  • the onboard ATP subsystem MVTP is compatible with modes of the movement authority and the speed code.
  • the movement authority is calculated for a train with a normal active positioning function and in ATP mode.
  • the target distance in step S3 is calculated for a train in ATP mode.
  • the present invention provides an implementation method for a CBTC method based on interval protection and heterogeneous redundancy, including the following steps:
  • Step S1 when active positioning functions of train 1 and train 2 are normal, trackside MWSP equipment (ATP interval protection equipment) calculates train movement authority based on active positioning information and a principle of the moving block, a train rear end of the train 2 is sent to the train 1 as a movement authority terminal, and onboard MVTP equipment of the train 1 calculates a safety protection curve based on the received movement authority and assists in train running.
  • trackside MWSP equipment ATP interval protection equipment
  • Step S2 when onboard MVTP equipment of the train 2 has a fault and loses positioning, the trackside MWSP equipment calculates the target distance and the speed code based on information about occupancy of a section (a track section 1) in which a non-positioning envelope of the train 1 is located, a permanent speed limit (80km/h) of a line, information about occupancy of a section (a track section 5) in which the train 2 is located, a state of trackside signaling equipment, and sends a speed code of each section to the train 1 out of position, and the train 1 is converted into a train under control of the quasi-moving block mode: the train 1 is away from the train 2 when running in the track section 1, so that the MWSP uses the permanent speed limit 80km/h of the line in the track section 1 as the speed code to be sent to the train 1; and a distance between the train 1 and the train 2 is shorter when the train 1 runs in a track section 2, the MWSP uses an entrance of the track section 5 as a
  • Step S3 when the train 1 is re-positioned during running in the quasi-moving block mode, the onboard MVTP equipment of the train 1 automatically switches back to a control mode of the moving block, namely, step S1 in the flow.
  • the present invention provides a CBTC system based on interval protection and heterogeneous redundancy.
  • the system includes an onboard ATP subsystem MVTP that is compatible with modes of the movement authority and speed code, a trackside ATP interval protection subsystem MWSP that can perform self-adaptive operations of a moving block mode and a quasi-moving block mode based on an active train positioning state, and a communication subsystem DCS between the train and the trackside.
  • Hardware of the MVTP and MWSP is one set of safety platforms, and the MVTP preferentially uses the movement authority information received from the trackside.
  • the target distance (ATP mode) or speed code information (RM mode) is considered when the movement authority information is not available, and safe train running protection is performed based on the received available information.
  • the MWSP automatically identifies and uses a corresponding block mode based on a positioning state, a driving mode, and other information sent by the train, and calculates the movement authority (of a train that is positioned in ATP mode), the target distance (of a train that is not positioned in ATP mode) or a speed code (of a train in an RM mode) in a corresponding block mode.
  • a calculation result is sent to onboard equipment of a corresponding train through train-ground communication.
  • the electronic device in the present invention includes a central processing unit (CPU), which can perform various proper actions and processing based on computer program instructions stored in a read-only memory (ROM) or computer program instructions loaded from a storage unit to a random access memory (RAM).
  • the RAM also stores various programs and data that are necessary for device operation.
  • the CPU, ROM, and RAM are connected to each other via a bus.
  • An input/output (I/O) interface is also connected to the bus.
  • the processing unit performs the methods and processing described above, such as the method in the present invention.
  • the method in the present invention may be implemented as computer software programs that are tangibly included in a machine-readable medium, such as a storage unit.
  • some or all of the computer programs may be loaded and/or installed onto the device via the ROM and/or communication unit.
  • the CPU may be configured to perform the method in the present invention in any other proper manner (for example, with the help of firmware).
  • hardware logic components that can be used as examples include, unlimitedly, a field-programmable gate array (FPGA), an application-specific integrated circuit (ASIC), an application-specific standard product (ASSP), a system-on-chip (SOC), a complex programmable logic device (CPLD), and the like.
  • FPGA field-programmable gate array
  • ASIC application-specific integrated circuit
  • ASSP application-specific standard product
  • SOC system-on-chip
  • CPLD complex programmable logic device
  • Program code for implementing the method in the present invention may be written in any combination of one or more programming languages.
  • the program code may be provided to processors or controllers of general-purpose computers, specialized computers, or other programmable data processing devices, so that when the program code is executed by the processors or controllers, functions/operations specified in flowcharts and/or block diagrams are implemented.
  • the program code can be executed entirely on a machine, partially on the machine, partially on the machine and partially on a remote machine as a separate software package, or entirely on the remote machine or server.
