Description

A method for group train departure within a station Technical Field

[0001] The present invention relates to a method for group trains to depart from a station. Background Art

[0002] Group train control involves direct exchange of control information between multiple trains, independent of physical connections. This allows for safe following of multiple trains at dynamic speed limits, dynamic interval limits, and coordinated control, allowing multiple trains to operate as a single, safe train. This train group control technology ensures the safe operation of heavy-load trains, improves transportation efficiency, enhances operational quality, and adapts to and meets the needs of development.

[0003] When a large train cannot be guaranteed to run as a whole or stop due to problems with the line or station ahead, the large train needs to be decomposed into small trains in advance to increase the line's capacity without modifying the line.

[0004] Train-to-train communication technology enables inter-train information exchange. Following trains calculate a dynamic safe tracking distance based on the lead train's real-time speed, position, and other status information, shortening the tracking distance. In complex station conditions, the primary challenge for train control is how to ensure that there are no other trains or vehicles between them, ensuring safe and efficient marshaling and departure while complying with interlocking logic check rules.

[0059] In general, the group train in-station marshaling departure method of the present invention includes the following steps:

[0060] S01. The centralized train dispatching system specifies a marshaling plan for the marshaling train and distributes it to the lead and following trains awaiting marshaling departure via the Temporary Speed ​​Reduction Server (TSRS). The marshaling plan includes information about the marshaling train, marshaling sequence, marshaling track, departure time, transit stations, and disengagement stations. Figure 1 shows a schematic diagram of a station yard with a mid-fork section. The mid-fork signal is the SIIL signal shown in the figure, and the mid-fork section is in front of the mid-fork signal. The lead and following trains awaiting marshaling departure are those in a state awaiting marshaling and are ready to depart once marshaling is complete.

[0061] S10. As shown in Figure 2, the lead train and the following trains to be marshaled for departure enter the mid-fork approach route containing a mid-fork section. The lead train enters the mid-fork section, with the lead train positioned ahead of the following trains in the departure direction. Alternatively, the lead train and the following trains may enter the station as a large train and then be demarshalled into two small trains. These two small trains serve as the lead train and the following trains. In this state, the lead train occupies the mid-fork section, and the mid-fork signal is closed.

[0062] S20: The first vehicle establishes communication with the Group Control Center (GCC) system and sends the first vehicle's position to the GCC system. The GCC system then completes the positioning of the first vehicle.

[0063] S30. The first vehicle drives out in the departure direction in a visual mode until the rear end of the first vehicle passes the middle fork section.

[0064] S40: The interlocking system detects that the middle fork section is in a cleared state within a time threshold. In this embodiment, the time threshold is 13 seconds. As shown in Figure 3, the group control center system confirms that there are no other trains between the tail end of the lead train and the middle fork section, indicating that the group control center has successfully set the lead train tail screening.

[0065] S50: The following vehicle establishes communication with the group control center system and sends the position of the following vehicle to the group control center system. As shown in FIG4 , the group control center system completes the positioning of the following vehicle.

[0066] S60: A center fork signal is installed in the center fork section. The group control center system transmits approaching train information from the center fork signal to the interlocking system. This approaching train information includes whether the approaching train type is a communication train and whether the group train type is a non-group train, allowing the signal to detect that the approaching train is a non-group train. The interlocking system opens the center fork signal for the following train, allowing departure. Specifically, the interlocking system performs special logic processing on the center fork signal. When determining the opening conditions of the center fork signal, the occupancy status of the center fork section of the center fork approach route is not checked.

[0067] S70. The interlocking system sends the information that the middle fork section is in the open state to the group control center system. The group control center system checks the status of the middle fork approach, specifically including not checking the occupancy status of the middle fork section, but only checking the switch position and the status of the middle fork signal to be normal.

[0068] S80: The group control center sends a forward track idleness confirmation request message to the following vehicle, specifically including the group control center sending the forward track idleness confirmation request message to the following vehicle and displaying the message to the following vehicle driver through a display screen of the following vehicle.

[0069] S90: The following vehicle sends an idle confirmation message to the group control center, specifically including:

[0070] S91. The driver of the following vehicle obtains information about the idle track ahead. In this embodiment, the driver of the following vehicle obtains the information about the idle track ahead by looking out.

[0071] S92. The driver of the following vehicle feeds back idle confirmation information to the group control center through the display screen. In this embodiment, the driver of the following vehicle feeds back idle confirmation information to the group control center by clicking the display screen.

[0072] S100. The group control center calculates a first driving permit for the following vehicle to the rear end position of the leading vehicle, and sends the first driving permit to the following vehicle, wherein the destination type of the first driving permit is a train, and the train identification information (Identity document, ID) is the identification information of the leading vehicle; and the group control center sends a second driving permit to the leading vehicle.

[0073] S110: After receiving the second driving permit, the lead vehicle establishes communication with the following vehicle according to the marshaling plan. After both the lead vehicle and the following vehicle determine that the marshaling conditions are met, they each confirm the departure information with the group control center. Specifically, confirming the departure information with the group control center includes the lead vehicle and the following vehicle each sending a request confirmation message to the group control center. After receiving the message, the group control center confirms that the vehicle marshaling is successful and sends a confirmation message to each of the lead vehicle and the following vehicle.

[0074] S120. As shown in Figure 5, a track signal SII is provided at one end of the departure direction of the middle fork approach. When the track signal is opened, the group control center calculates the third driving permit for the group train and sends it to the group train, and the group train enters the departure section.

[0075] In exceptional circumstances, if the lead train passes through the middle fork section without establishing communication with the group control center system, the dispatcher and station attendant will need to manually confirm that there are no other trains between the trains to be marshaled. The centralized train dispatching system then directly issues a marshaling command to the group control center and interlocking system. This command includes information about the marshaling train, marshaling location, and marshaling sequence. Based on the marshaling command, the group control center completes the tail screening of the lead train (that is, confirming that there are no other trains between the tail of the lead train and the middle fork section) and the head screening of the following trains. The interlocking system then opens the middle fork route and executes steps S70-S110.

[0076] Although the present invention has been described in detail through the above preferred embodiments, it should be understood that the above description is not intended to limit the present invention. After reading the above description, various modifications and substitutions of the present invention will become apparent to those skilled in the art. Therefore, the scope of protection of the present invention should be defined by the appended claims.
