Description

TECHNICAL FIELD

[0001] The present invention relates to the field of train signal control, and in particular to a method and a system for controlling inter-station remote train door opening based on CBTC, a device, and a storage medium.DESCRIPTION OF RELATED ART

[0002] At present, a commonly used signal system in urban rail transit is a train control system (CBTC) based on train-ground wireless communication. With the development of technologies and the improvement of a signal system automation grade, a GoA4 fully automatic unmanned subway CBTC system has been used in an increasing number of cities.

[0003] For the GoA4 unmanned CBTC system, due to the lack of a driver, passengers are usually forced to stop and evacuate in a train section under remote guidance of a control central operator, so that the passengers activate an emergency handle to unlock a train door and manually open the train door. In addition, because the passengers rarely use the passenger emergency handle, the passengers are not familiar with an operation of activating the passenger emergency handle, a sudden evacuation scenario can cause emotional tension among passengers, and it takes a long time for the passengers to open the train door and get off the train for evacuation, which poses a risk in case of an emergency situation that requires getting off the train within a short period of time.

[0004] In addition, because drivers are provided for traditional manned GoA2 and GoA3 subway CBTC systems, when a train is forced to stop in a section and passengers need to get off for evacuation, the driver and a control central operator can manually open a train door to guide the passengers to get off for evacuation after determining a safe evacuation condition. However, if the driver loses ability to act, such as sudden illness, and the passengers need to get off for evacuation, the passengers can only wait inside the train for other rescues, such as rescue by other drivers near the train.

[0005] After searching, the Chinese invention patent application CN116714642A discloses a method for train section evacuation protection. In this method, in response to a section evacuation request sent by a current train, an evacuation protection region is established for the current train based on current train positioning information and an operation direction, and evacuation protection is provided for other trains related to the evacuation protection region. In the above technology, a process of providing the evacuation protection region is only provided, but a way for remotely controlling the train door opening is not provided.

[0006] Therefore, it is necessary to consider a method for controlling inter-station remote train door opening in the above scenario.SUMMARY OF THE INVENTION

[0007] The present invention provides a method and a system for controlling inter-station remote train door opening based on CBTC, a device, and a storage medium, to overcome the defects in the prior art, which can effectively, safely, remotely, and actively control section-based train door opening.

[0019] In a preferred technical solution, a process for determining whether the train is currently located in the evacuation platform: the onboard controller determines whether a whole train is inside the evacuation platform based on self-positioning information and a mileage range of the evacuation platform in the built-in electronic map.

[0020] In a preferred technical solution, the inter-station remote train door opening instruction is transmitted through an interface between the ATS subsystem and the onboard controller.

[0021] In a preferred technical solution, within one effective communication period between the ATS subsystem and the onboard controller, the train performs remote door opening control if receiving a remote door opening instruction; otherwise, it is considered that the train does not meet a requirement for remote door opening.

[0022] In a preferred technical solution, the remotely guiding passengers to enter the evacuation platform after opening the train door is performed in manners including train broadcasting, a train passenger information subsystem (PIS), and train emergency intercom.

[0049] Next, the method in this embodiment is described in detail with reference to FIG. 1 and FIG. 2.

[0050] S1: The ATS subsystem receives the instruction from the control central operator on the ATS man-machine interface (HMI) based on train information, such as a train number, and issues the remote door opening instruction to the selected train;

[0051] S2: If the train receives the remote door opening instruction within one effective communication cycle of the ATS to the onboard controller, perform S3; otherwise, perform S8;

[0052] S3: The onboard controller determines whether the train stops steadily by checking if the train is at zero speed, and if the train stops steadily, perform S4; otherwise, perform S8;

[0059] S10: The control central operator organizes passenger evacuation in other manners, such as using train broadcast to inform passengers of turning a passenger emergency handle to an unlock position and manually open the train door.

[0060] The above is an introduction to the method embodiments. The following further describes solutions in the present invention by using a system for controlling inter-station remote train door opening based on CBTC.

[0061] The system relies on a train control system CBTC based on train-ground wireless communication, which specifically includes:

[0062] a remote inter-station train door opening issuance module, configured to interact, by a control central operator, with an ATS subsystem through an HMI, and receive, by the ATS subsystem, an instruction from the control central operator and issue a section-based remote door opening instruction to a selected train; and

[0063] a remote inter-station train door opening command module, configured to control, by an onboard controller after receiving the section-based remote door opening instruction, door opening based on current train state information, including:

[0064] if a train stops steadily and is currently located in an evacuation platform, authorizing, by the onboard controller, opening of a train door on a side with the evacuation platform, obtaining, by the control central operator, feedback information of successful remote door opening through the HMI and remotely guiding passengers to enter the evacuation platform after opening the train door; or

[0065] if a train does not stop steadily or if the train stops steadily but is not currently located in an evacuation platform, determining that the train does not meet a requirement for remote door opening, providing feedback to the control central operator through the HMI, and remotely guiding, by the control central operator after learning remote door opening failure information, passengers to manually open the train door for evacuation.

[0066] A system data flow direction shown in FIG. 2 includes:

[0067] the control central operator interacts with the ATS system through the man-machine interface (HMI), the remote door opening instruction issued by the ATS subsystem to the onboard controller is confirmed again, to prevent an operator error on an interface, and the ATS subsystem also feeds back an execution result to the HMI for the operator to view, forming a closed-loop feedback on the execution result of the instruction; and

[0068] the ATS subsystem feeds back train information, including a train position, a train door state, and the like, to the HMI. The train-ground wireless communication between the ATS and the onboard controller reuses an existing channel, and only needs to add a “door opening instruction issuance” code bit in an existing train-ground wireless channel and an interface protocol between the ATS of the CBTC and the onboard controller. A train door state is already included in original CBTC train-ground wireless transmission information. After successfully receiving the issued door opening instruction, the onboard controller issues door opening enabling (usually only enabling when the train is parked precisely at a platform) in a section to the train, and opens a door on a side with a corresponding evacuation platform. The control central operator informs passengers of evacuating in an orderly manner based on an operational evacuation plan and procedure.

[0069] A technical person in the field can clearly understand that for the convenience and simplicity of description, for a specific working process of the described module, reference may be made to a corresponding process in the above embodiments of the method, which is not repeated herein.

[0070] 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.

[0071] A plurality of components in the device are connected to the I / O interface, including: input units, such as a keyboard and a mouse; output units, such as various types of displays and speakers; storage units, such as a disk and an optical disc; and communication units, such as a network card, a modem and a wireless communication transceiver. The communication unit allows the device to exchange information / data with other devices through a computer network such as the Internet and / or various telecommunication networks.

[0072] The processing unit performs each of the methods and processes described above, such as methods S1 to S10. For example, in some embodiments, the methods S1 to S10 may be realized as a computer software program that is physically contained in a machine-readable medium, such as a storage unit. In some embodiments, parts or all of the computer program may be loaded and / or installed on the device via the ROM and / or the communication unit. When the computer program is loaded into the RAM and executed by the CPU, one or more steps of the methods S1 to S10 described above can be performed. Alternatively, in other embodiments, the CPU may be configured to execute the methods S1 to S10 by any other appropriate manner (e.g., with the help of firmware).

[0073] The functions described above herein can be performed, at least in part, by one or more hardware logical components. For example, without limitation, demonstration types of hardware logic components that can be used include: 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 so on.

[0074] The program codes for implementing the method of the present invention may be written in any combination of one or more pieces of programming language. These program codes may be provided to a processor or controller of a general-purpose computer, a special-purpose computer or another programmable data processing device so that the program code, when executed by the processor or controller, implements the functions / operations specified in the flow chart and / or block diagram. The program codes can be executed entirely on a machine, partially on a machine, partially on a machine and partially on a remote machine or completely on a remote machine or server as a stand-alone software package.

[0075] In the context of the present invention, the machine readable medium may be a tangible medium that may contain or store a program for use by or in conjunction with an instruction executing system, apparatus or device. The machine readable medium may be a machine readable signal medium or a machine readable storage medium. The machine readable medium may include, but is not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any suitable combination of the above. More specific examples of the machine readable storage medium would include an electrical connection based on one or more wires, a portable computer disk, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable ROM (EPROM or flash memory), an optical fiber, a convenient compact disk ROM (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the above.

[0076] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited to this, and any technical person familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, which shall be covered by the protection scope of the present invention.

[0056] S7: The control central operator remotely organizes passengers to get up for evacuation in manners such as train broadcasting, train PIS, and train emergency intercom;

[0057] S8: The train does not meet the requirement of remote door opening, and door opening fails;

[0058] S9: The onboard controller sends an alarm of door opening failure to the ATS HMI; and

[0059] S10: The control central operator organizes passenger evacuation in other manners, such as using train broadcast to inform passengers of turning a passenger emergency handle to an unlock position and manually open the train door.

[0060] The above is an introduction to the method embodiments. The following further describes solutions in the present invention by using a system for controlling inter-station remote train door opening based on CBTC.

[0061] The system relies on a train control system CBTC based on train-ground wireless communication, which specifically includes:

[0062] a remote inter-station train door opening issuance module, configured to interact, by a control central operator, with an ATS subsystem through an HMI, and receive, by the ATS subsystem, an instruction from the control central operator and issue a section-based remote door opening instruction to a selected train; and

[0063] a remote inter-station train door opening command module, configured to control, by an onboard controller after receiving the section-based remote door opening instruction, door opening based on current train state information, including:

[0064] if a train stops steadily and is currently located in an evacuation platform, authorizing, by the onboard controller, opening of a train door on a side with the evacuation platform, obtaining, by the control central operator, feedback information of successful remote door opening through the HMI and remotely guiding passengers to enter the evacuation platform after opening the train door; or

[0065] if a train does not stop steadily or if the train stops steadily but is not currently located in an evacuation platform, determining that the train does not meet a requirement for remote door opening, providing feedback to the control central operator through the HMI, and remotely guiding, by the control central operator after learning remote door opening failure information, passengers to manually open the train door for evacuation.

[0066] A system data flow direction shown in FIG. 2 includes:

[0067] the control central operator interacts with the ATS system through the man-machine interface (HMI), the remote door opening instruction issued by the ATS subsystem to the onboard controller is confirmed again, to prevent an operator error on an interface, and the ATS subsystem also feeds back an execution result to the HMI for the operator to view, forming a closed-loop feedback on the execution result of the instruction; and

[0068] the ATS subsystem feeds back train information, including a train position, a train door state, and the like, to the HMI. The train-ground wireless communication between the ATS and the onboard controller reuses an existing channel, and only needs to add a “door opening instruction issuance” code bit in an existing train-ground wireless channel and an interface protocol between the ATS of the CBTC and the onboard controller. A train door state is already included in original CBTC train-ground wireless transmission information. After successfully receiving the issued door opening instruction, the onboard controller issues door opening enabling (usually only enabling when the train is parked precisely at a platform) in a section to the train, and opens a door on a side with a corresponding evacuation platform. The control central operator informs passengers of evacuating in an orderly manner based on an operational evacuation plan and procedure.
