Description

Technical Field

[0001] This invention relates to a method for group trains to depart from a station. Background Technology

[0002] Train group control refers to the operation of multiple trains without physical connections, through direct control information exchange between trains. This allows multiple trains to operate safely as a single train by maintaining dynamic speed limits, dynamic interval limits, and coordinated control. Train group operation control technology can ensure the safe operation of heavy-haul trains, improve transportation efficiency, enhance operational quality, and adapt to and meet the needs of development.

[0003] When the operation or stopping of a large train cannot be guaranteed due to reasons related to the track or station ahead, the large train needs to be broken down into smaller trains in advance to improve the track's throughput capacity without requiring track modifications.

[0004] Train convoys exchange information with each other via car-to-car communication technology. Following cars calculate the dynamic safe tracking distance based on the real-time speed, position, and other status information of the lead car, thus shortening the tracking distance. In complex station conditions, the primary challenge for train convoy control is ensuring that no other trains or vehicles are between two cars within the station, thereby enabling safe and efficient convoy departure while adhering to interlocking logic check rules.

[0052] It should be noted that, in this invention, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only the expressly listed elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0053] like Figure 6 As shown, the present invention provides a method for group trains to depart from a station, the method comprising:

[0054] The lead car and following cars, awaiting departure, enter the fork section of the train's route. The lead car enters the fork section and is positioned ahead of the following cars in the departure direction. The lead car exits the fork section. The interlocking system collects data on the fork section being cleared within a certain time threshold and sends it to the group control center system. The group control center system confirms that there are no other trains between the rear of the lead car and the fork section. The following cars are located. The following cars confirm that the track ahead is clear. The lead car and following cars then enter the departure section as a train.

[0055] The process of the first vehicle leaving the forklift section includes S20, where the first vehicle establishes communication with the group control center system and sends its position to the group control center system, and the group control center system completes the positioning of the first vehicle; and S30, where the first vehicle leaves the forklift section in the direction of departure.

[0056] The positioning of the following train includes S50: the following train establishes communication with the group control center system and sends its position to the group control center system, and the group control center system completes the positioning of the following train; S60: a fork signal is installed on the fork section, and the group control center system sends the approaching train information of the fork signal to the interlocking system; the interlocking system opens the fork signal for the following train to allow departure; S70: the interlocking system sends the status of the fork section to the group control center system, and the group control center system checks the status of the fork route.

[0057] The process of the following vehicle confirming that the track ahead is free includes S80, where the group control center sends a request message to the following vehicle to confirm that the track ahead is free; and S90, where the following vehicle sends a confirmation message to the group control center to confirm that the track is free.

[0058] The process of the lead car and following cars entering the departure section includes: S100, the group control center calculates the first driving permission for the following cars up to the rear of the lead car and sends the first driving permission to the following cars; and the group control center sends the second driving permission to the lead car; S110, after receiving the second driving permission, the lead car establishes communication with the following cars. After both the lead car and the following cars determine that the formation conditions are met, they confirm the departure information with the group control center respectively; S120, a track signal is provided at one end of the departure direction of the forklift route. When the track signal is open, the group control center calculates the third driving permission for the group train and sends it to the group train, and the group train enters the departure section.

[0059] Overall, the group train in-station formation and departure method of the present invention includes the following steps:

[0060] S01. The centralized train dispatching system assigns a marshalling plan to each train and distributes it to the lead and following cars via a Temporary Speed ​​Reduction Server (TSRS). The marshalling plan includes information on the trains, marshalling sequence, marshalling tracks, departure time, stations along the route, and demarcation / demarcation stations. For example... Figure 1 The diagram shows a station layout including a center fork section. The center fork signal is the SIIL signal in the diagram, and the area in front of the center fork signal is the center fork section. The lead car and following cars awaiting formation refer to the lead car and following cars that are in a waiting-to-be-formed state; they can depart in formation once formation is complete.

[0061] S10, such as Figure 2As shown, the lead car and following cars, awaiting departure, enter the forklift route containing the forklift section. The lead car, upon entering the forklift section, is positioned ahead of the following cars in the departure direction. Alternatively, the lead car and following cars can enter the station as a large train formation and then be decoupled into two smaller train formations, which are the lead car and following cars. In this state, the lead car occupies the forklift section, and the forklift signal is closed.

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

[0063] S30, the first vehicle departs in visual mode along the departure direction until the rear of the first vehicle crosses the middle fork section.

[0064] S40. The interlocking system detects that the intermediate fork section is in a cleared state within a certain time threshold. In this embodiment, the time threshold is 13 seconds. Figure 3 As shown, the group control center system confirmed that there were no other trains between the rear end of the first train and the middle fork section, meaning that the group control center successfully set up the screening at the rear end of the first train.

[0065] S50: The following vehicle establishes communication with the group control center system and sends the following vehicle's location to the group control center system, such as... Figure 4 As shown, the group control center system completes the positioning of the following vehicle.

[0066] S60. A center fork signal is installed on the center fork section. The group control center system sends the approaching train information of the center fork signal to the interlocking system. The approaching train information includes whether the approaching train type is a communication car and whether the group train type is a non-group train, so that the signal can know that the approaching train is a non-group train. The interlocking system grants departure permission by opening the center fork signal for the following train. Specifically, the interlocking system performs special logic processing on the center fork signal. When determining the opening condition of the center fork signal, it does not check the occupancy status of the center fork section of the center fork route.

[0067] S70. The interlocking system sends a message to the group control center system indicating that the middle fork section is open. The group control center system checks the status of the middle fork route, specifically by not checking the occupancy status of the middle fork section, but only checking the turnout position and the status of the middle fork signal to be normal.

[0068] S80, the group control center sends a confirmation message that the track ahead is clear to the following vehicle. Specifically, the group control center sends the confirmation message to the following vehicle and displays it to the driver of the following vehicle through the following vehicle's display screen.

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

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

[0071] S92. The following vehicle driver sends an idle confirmation message to the group control center via the display screen. In this embodiment, the following vehicle driver sends an idle confirmation message to the group control center by clicking on the display screen.

[0072] S100, the group control center calculates the first driving permission to the rear end position of the lead vehicle for the following vehicle, and sends the first driving permission to the following vehicle. The destination type of the first driving permission is train, and the train's identification information (IdentityDocument, ID) is the identification information of the lead vehicle. The group control center also sends the second driving permission to the lead vehicle.

[0073] S110. After receiving the second travel permit, the lead car establishes communication with the following cars according to the formation plan. Once both the lead and following cars determine that the formation conditions are met, they respectively confirm the departure information with the group control center. Specifically, confirming the departure information with the group control center involves both the lead and following cars sending confirmation requests to the group control center. After receiving the information, the group control center confirms that the car formation is successful and replies with confirmation messages to both the lead and following cars.

[0074] S120, such as Figure 5 As shown, a track signal SII is installed at one end of the departure direction of the middle fork route. When the track signal is open, the group control center calculates the third train travel permission for the group train and sends it to the group train, and the group train enters the departure section.

[0075] In special circumstances, if the lead car passes through the fork section without establishing communication with the group control center system, the dispatcher and station duty officer need to manually confirm that there are no other cars between the trains to be assembled. The centralized train dispatching system then directly issues a marshalling command to the group control center and interlocking system. This marshalling command includes information on the trains to be assembled, their assembly positions, and the assembly sequence. Based on the marshalling command, the group control center completes the tail screening of the lead car (i.e., confirming that there are no other trains between the rear of the lead car and the fork section) and the head screening of the following cars. The interlocking system then opens the fork route and executes steps S70-S110.

[0076] Although the present invention has been described in detail through the preferred embodiments above, it should be understood that the above description should not be considered as a limitation of the present invention. Various modifications and substitutions to the present invention will be apparent to those skilled in the art after reading the above description. Therefore, the scope of protection of the present invention should be defined by the appended claims.
