[0034] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention.

[0035] This invention provides an interlocking control system based on diversified stations. By setting function modules and parameter modules for specific interlocking control units, the interlocking control unit can be highly adapted to complex stations. The system includes a dispatching control unit, a turnout control unit, a track control unit, and an interlocking interface unit.

[0036] Scheduling control unit: includes a scheduling function module and a scheduling general parameter module. The scheduling function module obtains scheduling instructions to execute scheduling tasks, and the scheduling general parameter module inputs scheduling parameters to the scheduling function module.

[0037] Reference Figure 1 The dispatching function module includes a dispatching operation command module, a dispatching status display module and an adjacent interlocking communication module.

[0038] The scheduling operation command module obtains the scheduling authority control instruction from the scheduling system, performs logical calculation with the current scheduling control mode, and generates a new scheduling control mode.

[0039] The dispatch status display module feeds back the current dispatch control mode to the dispatch system in real time for display.

[0040] The adjacent interlocking communication module sends the current interlocking scheduling control mode to the adjacent interlocking control area in real time, and receives the scheduling control module sent from the adjacent interlocking control area.

[0041] The dispatch general parameter module includes: a safety command confirmation time parameter: when the dispatch operation command module receives a dispatch authority control instruction from the dispatch system, the safety command confirmation time parameter starts counting. Within the specified time, the interlocking system must receive a confirmation command from the dispatch system; otherwise, the dispatch authority control instruction will not be executed by the interlocking system. A command blocking time parameter: when the interlocking system is powered on and switched back, the command blocking time parameter starts counting. Within the specified time, the interlocking system will not execute any dispatch authority control instruction from the dispatch system. An emergency authorization safety confirmation parameter: this parameter can be set to emergency authorization safety confirmation or emergency authorization without safety confirmation. When the emergency authorization safety confirmation parameter is set to emergency authorization without safety confirmation, the interlocking system will take effect immediately after receiving the emergency authorization command from the dispatching system. When the emergency authorization safety confirmation parameter is set to emergency authorization safety confirmation, the interlocking system will need to send a confirmation command to the interlocking system again after receiving the emergency authorization command from the dispatching system. The emergency authorization will only take effect after the interlocking system receives the confirmation command.

[0042] Scheduling control unit workflow:

[0043] Step 1: The scheduling operation command module receives the scheduling authority control command of the scheduling system;

[0044] Step 1.1: Perform a logical calculation on the received dispatch authority control instruction and the current dispatch control mode to obtain a new dispatch control mode;

[0045] Step 2: The dispatching status display module feeds back the current interlocking dispatching control mode to the dispatching system in real time for display;

[0049] Reference Figure 2 As shown, the turnout parameter module includes a turnout general parameter module, a turnout topology parameter module and a turnout special parameter module;

[0050] The switch general parameter module includes switch rotation time monitoring parameters and zone controller parameters. The switch rotation time monitoring parameter defines the time required for a switch to rotate from one position to another. If the actual switch rotation time exceeds the time defined by this parameter, the interlocking will stop outputting the current switch rotation command. The zone controller parameters can define whether the switch sends status to the zone controller or not, allowing for flexible configuration of switches according to automated and non-automated zones.

[0051] The switch topology parameter module includes double-action switch parameters, default position parameters, side protection parameters, and intrusion protection parameters. Double-action switch parameters configure the switch in single-action or double-action switch mode according to the topological structure of the switch in the station yard; default position parameters set the default position of the switch to fixed or reverse position according to the topological structure of the switch in the station yard; side protection parameters set the switch to the side protection switch of the corresponding route according to the topological structure of the switch in the station yard; intrusion protection parameters set the switch to the intrusion protection switch of the corresponding route according to the topological structure of the switch in the station yard.

[0052] The switch special parameter module includes switch automatic return parameters and switch automatic return time parameters. The switch automatic return parameter sets a preset position for the switch according to the special conditions of the line. When the switch is not in the preset position, the switch will automatically return to the preset position. The switch automatic return time parameter sets a switch automatic return time for the switch according to the special conditions of the line. When the switch is not in the preset position, the time parameter starts counting. After the timer ends, the switch will automatically return to the preset position.

[0053] Turnout control unit workflow:

[0054] Step 1: When the switch command execution module receives the switch operation command from the dispatching system, it compares the operation command with the current switch state. If the operation command is consistent with the current switch state, the command is not executed; if the operation command is inconsistent with the current switch state, the command is executed;

[0055] Step 2: The turnout status acquisition module receives the status information from the turnout and records the information in the interlocking storage.

[0056] Track control unit: includes a track function module and a track parameter module; the track function module obtains track operation instructions and performs track operation tasks, and the track parameter module inputs track operation parameters to the track function module.

[0057] Reference Figure 3As shown, the track function module includes a track command execution module and a track status acquisition module; the track command execution module receives track operation commands from the dispatching system; the track status acquisition module collects track status information transmitted from the trackside.

[0061] The track-specific parameter module includes emergency button parameters and route direction parameters. Emergency button parameters can be set for a track if it has an associated emergency button. Route direction parameters define the default route direction for a track.

[0062] Track control unit workflow:

[0063] Step 1: After receiving the track blocking command from the dispatching system, the track command execution module blocks the corresponding track;

[0064] Step 2: The track status acquisition module receives status information from the track and records the information in the interlocking storage.

[0065] Interlocking interface unit: includes an interlocking interface function module and an interlocking interface parameter module. The interlocking interface function module is electrically connected to the scheduling system and outputs interlocking status information.

[0067] The interlocking interface parameter module includes an interface type parameter, which is used to set whether the interface of adjacent interlocking control areas belongs to the main line interlocking interface or the main line and vehicle depot interlocking interface.

[0068] Interlocking interface unit workflow:

[0069] Step 1: The interlocking interface display module determines whether the current interlocking system has successfully established a connection with the adjacent interlocking system by judging the health status of the adjacent interlocking system, and sends the interface status to the dispatching system for display;

[0070] Step 2: The interlocking interface communication module receives health information from adjacent interlocking systems and sends the health information of the current interlocking system to the adjacent interlocking system to establish an information interaction link between adjacent interlocking control areas.
