Description

Technical Field

[0001] This invention relates to train signal control systems, and more particularly to a method, device, and medium for enabling alignment isolation based on a signal system. Background Technology

[0002] With the development of urban rail transit, the alignment and isolation function between train doors and platform doors has been widely used in the construction of traditional CBTC systems and fully automated operation systems. Typically, to ensure efficient and safe passenger boarding and alighting and to improve operational efficiency, in the event of a malfunction of an individual train door or platform door, the alignment and isolation function prevents the platform door corresponding to the malfunctioning train door or the train door corresponding to the malfunctioning platform door from opening and closing after the train enters the station, thus ensuring consistency between the opening and closing of the platform door and the train door.

[0003] However, in special circumstances, such as when the platform screen door system or the vehicle's logic for determining the alignment and isolation status malfunctions due to software errors or hardware failures, alignment and isolation information may be sent when no alignment and isolation operation is required. This can lead to incorrect alignment and isolation issues (for example, if the platform screen door malfunction information from the previous station is not cleared after the train leaves the previous station, the train may incorrectly execute the previous station's platform screen door alignment and isolation command when it arrives at the next station), thus affecting normal operational organization.

[0004] Therefore, when implementing the alignment isolation function, there is an urgent need to provide operators with a means to enable the alignment isolation function. This means can enable or disable the alignment isolation function for a specific station or all stations under its jurisdiction under certain circumstances. The operational requirements for enabling (enabling and disabling) the alignment isolation function are also particularly important.

[0005] Currently, the information transmission timing for the alignment and isolation function between train doors and platform doors in urban rail transit is as follows:

[0006] 1. When the train head enters the platform rail, the signal ATS (Automatic Train Supervision) system is responsible for forwarding the faulty platform door alignment isolation information to the train, and at the same time forwarding the faulty car door alignment isolation information of the train to the platform door system, thereby realizing the alignment isolation function of the faulty car door or the faulty platform door.

[0007] 2. Once the train head has entered the platform rails, if the alignment and isolation information of the train doors or platform doors changes, the ATS (Automatic Train Protection) system will continuously forward the updated door and platform door alignment and isolation information until the train comes to a complete stop at the platform. If the alignment and isolation information of the train doors or platform doors changes again during the train's stop, the ATS system will no longer forward the updated door and platform door alignment and isolation information, maintaining the original alignment and isolation information until the train has completely departed the station.

[0008] 3. After the train has finished stopping and completely left the platform track, the ATS (Automatic Train Protection) system sends a platform door and train door clearance and alignment message to ensure that the alignment information is in the default state after the train departs the station.

[0009] 4. When the train arrives at the next station, repeat steps 1 to 3.

[0010] Under normal conditions, when the alignment isolation communication links between the ATS system and the platform screen door system, the ATS system and the onboard CC system, and the onboard CC system and the vehicle are functioning correctly, the transmission of alignment isolation information and clearing information is accurate, thus ensuring that the platform screen door system and the vehicle can accurately perform alignment isolation functions.

[0011] Because existing technical solutions only consider routine operational scenarios, such as software malfunctions or hardware failures in the platform screen door system or the vehicle itself, alignment isolation information may be issued without performing platform screen door or vehicle door isolation operations. This will cause the alignment isolation function to err unexpectedly, significantly reducing the overall quality of operational services. In such cases, if dispatch confirms the issue and needs to stop the operation of the vehicle door and platform screen door alignment isolation function, troubleshooting can only be done manually, lacking a quick and effective solution. This has a significant impact on operations (such as delays) and places considerable workload on maintenance personnel.

[0012] CN116279689A discloses a method, apparatus, device, and medium for automatic alignment isolation of train doors and platform screen doors. The method includes two sub-methods: one for achieving automatic alignment isolation of train doors and platform screen doors based on a signal system, and the other for achieving automatic alignment isolation of platform screen doors and train doors based on a signal system. The apparatus includes a signal system, a vehicle system, and a platform screen door system. The signal system receives train door status and platform screen door status information sent by the vehicle and platform screen door systems, processes this information through parsing and logical operations, and converts the corresponding train door or platform screen door fault status into alignment isolation information, which is then sent to the platform screen door system and the vehicle, respectively, thereby achieving automatic alignment isolation of the faulty platform screen door or train door. However, this method can only achieve automatic alignment isolation and cannot automatically stop the alignment isolation function.

[0013] During the construction of urban rail transit, the installation and commissioning work of various trades cannot be carried out simultaneously. For example, if the installation and commissioning of platform screen doors are delayed, the alignment isolation function may not be ready for operation. There may be cases where the alignment isolation function of individual platform screen doors or an entire side of platform screen doors is not fully commissioned. To avoid confusion with the alignment isolation function of train doors, it is usually necessary to disable the alignment isolation function between platform screen doors and train doors, that is, to stop using the alignment isolation function. The alignment isolation function will be reactivated only after the entire interface function has been fully commissioned.

[0014] During routine maintenance and repair, there are often situations where multiple disciplines are simultaneously carrying out maintenance, dynamic adjustment, and construction. In order to avoid the impact of platform door maintenance or train door maintenance and testing on the dynamic adjustment and testing train or platform door, it is also necessary to stop the alignment and isolation function of the train door and platform door, so as to avoid cross-influence on the maintenance work of various disciplines.

[0015] In response to the above scenarios, if the positioning isolation function is to be discontinued, apart from dispatching personnel to disconnect the network communication link between the platform screen doors and the signal ATS system at each station, there is no corresponding technical means to quickly and effectively solve the above defects. Summary of the Invention

[0016] The purpose of this invention is to overcome the defects of the prior art by providing a method, device and medium for enabling alignment isolation based on a signal system. The aim is to improve the automation level, system response time and driving safety of urban rail transit systems, ensure passenger safety when boarding and alighting, and reduce the labor intensity of staff.

[0017] The objective of this invention can be achieved through the following technical solutions:

[0018] According to a first aspect of the present invention, a method for enabling alignment isolation based on a signal system is provided. The method involves a signal ATS system, a vehicle, and a platform door system. The signal ATS system identifies the operator's intention and determines whether alignment isolation is required based on the operation command to enable or disable alignment isolation. The system then sends a corresponding command to the vehicle and platform door systems to enable alignment isolation for the vehicle and platform doors.

[0019] As a preferred technical solution, the signal ATS system communicates with the platform door system and the vehicle, sending the required platform door alignment and isolation information to the platform door system and the required vehicle door alignment and isolation information to the vehicle.

[0020] The signal ATS system, based on the operational intentions of station duty officers or dispatchers, enables or deactivates the alignment and isolation functions of train doors and platform doors for the entire operating line or a specific station, and through logical operations, it integrates these functions with the dispatching operation intentions. Figure 1 The corresponding isolation instructions are forwarded to the vehicle and platform door systems.

[0021] As a preferred technical solution, the interface protocol for communication between the signal ATS system and the platform screen door system defines the meaning of the status. Status 1 represents that no platform screen door alignment and isolation information is required, and status 2 represents that platform screen door alignment and isolation information is required.

[0022] As a preferred technical solution, the interface protocol for communication between the signal ATS system and the vehicle defines the meaning of the states: state 1 represents that no door alignment isolation information is required, and state 2 represents that door alignment isolation information is required.

[0023] As a preferred technical solution, the operational intent of the station duty officer or dispatcher is determined based on the relevant enabling operations performed by the station duty officer on the station HMI or by the dispatcher on the control center MMI.

[0024] As a preferred technical solution, when the station duty officer or dispatcher activates the alignment isolation function on the HMI or MMI, the signal ATS system sends the alignment isolation information between the train doors and platform doors to the vehicle and platform door system, which then performs the alignment isolation function as required. When the station duty officer or dispatcher deactivates the alignment isolation function on the HMI or MMI, the signal ATS system sends the alignment isolation information between the train doors and platform doors to the vehicle and platform door system, which then does not perform the alignment isolation function based on this information.

[0025] As a preferred technical solution, when the station duty officer enables or disables the alignment isolation function on the station HMI, the operation only enables the alignment isolation function between the platform door and the train door of the station belonging to this interlocking zone.

[0026] As a preferred technical solution, when the dispatcher enables or disables the alignment isolation function on the control center MMI, the platform door and train door alignment isolation function of the entire operating line or a certain station can be enabled as needed.

[0027] As a preferred technical solution, the signal ATS system displays the alignment and isolation enable status of the train doors and platform doors on the station HMI and the ATS dispatching workstation in the control center, providing status prompts to station duty officers and dispatchers to facilitate the monitoring of the alignment and isolation enable status of the train doors and platform doors.

[0028] As a preferred technical solution, the platform screen door system communicates with the signal ATS system, receives information from the signal ATS system indicating whether a faulty door needs or does not require alignment isolation, and determines whether to perform the alignment isolation function based on the information sent by the signal ATS system.

[0029] As a preferred technical solution, the vehicle communicates with the signal ATS system, receives information from the signal ATS system indicating whether the faulty platform door needs or does not require alignment isolation, and determines whether to perform the alignment isolation function based on the information sent by the signal ATS system.

[0030] As a preferred technical solution, the method includes two scenarios: enabling operation performed by station duty personnel and enabling operation performed by control center dispatchers.

[0031] As a preferred technical solution, when the enabling operation is performed by the station duty officer, the method includes the following steps:

[0032] S1. The station duty officer determines whether an alignment isolation enabling operation is required.

[0033] S2. When the alignment isolation function between train doors and platform doors is required, the station duty officer shall enable the alignment isolation function for a specific station or all stations in this interlocking zone; when bypassing or stopping the alignment isolation function between train doors and platform doors is required, the station duty officer shall disable the alignment isolation function.

[0034] S3. The signal ATS system, based on the enabling operation of the alignment isolation function performed by the station duty officer in step S2, sends the alignment isolation information between the car door and the platform door to the vehicle and platform door system; or the signal ATS system, based on the enabling operation of the de-alignment isolation function performed by the station duty officer in step S2, sends the alignment isolation information between the car door and the platform door to the vehicle and platform door system.

[0035] S4. Based on the enabling or disabling of the alignment isolation function performed by the station duty officer in step S2, the signal ATS system displays the alignment isolation enable status information on the ATS workstation, indicating to the station duty officer or dispatcher that the alignment isolation function is currently enabled or disabled.

[0036] S5. The vehicle and platform door system performs the corresponding alignment isolation function when the train stops and opens and closes the doors, based on the alignment isolation information provided by the signal ATS system in step S3, or performs the normal door opening and closing linkage function, without performing the alignment isolation function, based on the alignment isolation information not required by the signal ATS system.

[0037] As a preferred technical solution, when the enabling operation is performed by a control center dispatcher, the method includes the following steps:

[0038] A1. The control center dispatcher determines whether a position isolation enabling operation is required.

[0039] A2. When the alignment isolation function between train doors and platform doors is required, the dispatcher shall enable the alignment isolation function for a specific station or all stations along the line; when the alignment isolation function between train doors and platform doors is required to be bypassed or deactivated, the dispatcher shall deactivate the alignment isolation function for a specific station or all stations along the line.

[0040] A3. The signal ATS system, based on the enabling operation of the alignment isolation function performed by the dispatcher in step A2, sends the alignment isolation information between the car door and the platform door to the vehicle and platform door system; or the signal ATS system, based on the enabling operation of the disabling alignment isolation function performed by the dispatcher in step A2, sends the alignment isolation information between the car door and the platform door to the vehicle and platform door system.

[0041] A4. Based on the enabling operation of the alignment isolation function performed by the dispatcher in step A2, the signal ATS system will display the alignment isolation enabling status information on the ATS workstation, indicating to the station duty officer or dispatcher that the current alignment isolation function is enabled or disabled.

[0042] A5. The vehicle and platform door system performs the corresponding alignment isolation function when the train stops and opens and closes the doors, based on the alignment isolation information provided by the signal ATS system in step A3, or performs the normal door opening and closing linkage function, without performing the alignment isolation function, based on the alignment isolation information not required by the signal ATS system.

[0043] According to a second aspect of the present invention, an electronic device is provided, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the program to implement the method described thereon.

[0044] According to a third aspect of the present invention, a computer-readable storage medium is provided having a computer program stored thereon, which, when executed by a processor, implements the method described thereon.

[0045] Compared with the prior art, the present invention has the following beneficial effects:

[0046] (1) This invention adds the function of enabling alignment isolation between train doors and platform screen doors to the signal ATS system, providing users with a quick and effective means to enable or disable the alignment isolation function between train doors and platform screen doors according to their needs under special circumstances. This alignment isolation enabling method can avoid the situation where the alignment isolation function is incorrectly performed under unexpected circumstances due to software errors or hardware failures in the platform screen door system or the vehicle itself.

[0047] (2) This invention provides an emergency response method for station duty officers and control center dispatchers through the signal ATS system, avoiding operational delays caused by waiting for maintenance personnel to handle the alignment isolation function failure during operation, which helps to improve the level of operation service and reduce the workload of operation and maintenance personnel.

[0048] (3) During the construction of urban rail transit, the installation and commissioning of platform screen doors and vehicles often cannot be guaranteed to proceed synchronously. For example, if the installation and commissioning of platform screen doors are delayed, the alignment isolation function may not be ready for operation. There may be cases where the alignment isolation function of individual platform screen doors or the entire side of platform screen doors is not fully commissioned. To avoid confusion with the alignment isolation function of the vehicle doors, it is usually necessary to disable the alignment isolation function of platform screen doors and vehicle doors until the interface function is fully commissioned before enabling the alignment isolation function. Through this invention, users can flexibly choose to enable or disable the alignment isolation function, providing an effective operational organization method for determining whether to use the alignment isolation function during line construction trial operation or later passenger operation.

[0049] (4) During routine maintenance and repair, there are often situations where multiple specialties are simultaneously carrying out maintenance, dynamic adjustment, and construction. To avoid the impact on the dynamic adjustment and testing train or platform screen doors during platform screen door maintenance or train door maintenance and testing, this invention allows users to flexibly choose to enable or disable the alignment isolation function, thereby avoiding cross-influence on maintenance operations of various specialties.

[0050] (5) In this invention, the synchronization of alignment isolation information involves the linkage between multiple systems such as the signal system, vehicle and platform door system. The alignment isolation enabling software function is added through the signal ATS system, with no hardware cost investment, while improving the linkage and integration between the entire system.

[0052] Figure 2 A flowchart illustrating the method for enabling position isolation in a signal ATS system. Detailed Implementation

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0054] This embodiment provides a method for enabling alignment isolation based on a signaling system. The method involves a signaling ATS system, a vehicle, and a platform door system. The signaling ATS system identifies the operator's intention and determines whether alignment isolation is required based on the operation command to enable or disable alignment isolation. The system then sends corresponding instructions on whether alignment isolation is required to the vehicle and platform door systems, thereby enabling alignment isolation for the vehicle doors and platform doors.

[0055] The signaling system communicates with the platform screen door system to send the required platform screen door alignment and isolation information (the interface protocol defines the meaning of the status, such as 1 means no platform screen door alignment and isolation information is needed, and 2 means platform screen door alignment and isolation information is needed) to the platform screen door system.

[0056] The signal system communicates with the vehicle to transmit the required door alignment isolation information (the interface protocol defines the meaning of the status, such as 1 indicating that door alignment isolation information is not required, and 2 indicating that door alignment isolation information is required).

[0057] The signaling system is capable of enabling (activating or deactivating) the alignment isolation function for train doors and platform doors on the entire operating line or at a specific station, based on the special scenario handling principles and usage requirements of station duty personnel or dispatchers. This enabling operation can be performed on the station HMI (Human-Machine Interface) or the control center MMI (Man-Machine Interface).

[0058] The signaling system is capable of activating or deactivating the alignment and isolation functions of train doors and platform doors at the entire line or a specific station based on the operational intentions of station staff or dispatchers. Through logical operations, it can also synchronize these actions with the dispatching instructions. Figure 1 The signal ATS system forwards the alignment isolation command to the vehicle and platform screen door systems. Specifically, when the station duty officer or dispatcher activates the alignment isolation function on the HMI or MMI, the signal ATS system sends the alignment isolation information for the vehicle and platform screen doors to the vehicle and platform screen door systems, which then execute the alignment isolation function as required. When the station duty officer or dispatcher deactivates the alignment isolation function on the HMI or MMI, the signal ATS system sends the alignment isolation information for the vehicle and platform screen doors to the vehicle and platform screen door systems, which then do not execute the alignment isolation function based on the information that no alignment isolation is required.

[0059] When station duty officers enable or disable the alignment isolation function on the station HMI, they only enable the alignment isolation function between platform doors and train doors for stations within their own interlocking zone. When dispatchers enable or disable the alignment isolation function on the control center MMI, they can enable the alignment isolation function between platform doors and train doors for all stations on the entire operating line or for a specific station, as needed.

[0060] The signal ATS system displays the alignment and isolation enable status of train doors and platform doors on the station HMI and the ATS dispatching workstation in the control center, providing status prompts to station duty officers and dispatchers to facilitate the monitoring of the alignment and isolation enable status of train doors and platform doors.

[0061] The platform screen door system communicates with the ATS (Automatic Train Protection) system, receives information from the ATS system indicating whether a faulty door needs or does not require alignment isolation, and determines whether to perform the alignment isolation function based on this information.

[0062] The vehicle communicates with the signal ATS system, receives information from the signal ATS system indicating whether the faulty platform door needs or does not require alignment isolation, and determines whether to perform the alignment isolation function based on the information sent by the signal ATS system.

[0063] In a preferred embodiment, the method includes two scenarios: enabling operation performed by a station duty officer and enabling operation performed by a control center dispatcher.

[0064] When the enabling operation is performed by the station duty officer, the method includes the following steps:

[0065] S1. The station duty officer determines whether it is necessary to perform an alignment isolation enabling (enable or deactivate) operation;

[0066] S2. When the alignment isolation function between train doors and platform doors is required, the station duty officer shall enable the alignment isolation function for a specific station or all stations in this interlocking zone; when bypassing or stopping the alignment isolation function between train doors and platform doors is required, the station duty officer shall disable the alignment isolation function.

[0067] S3. The signal ATS system, based on the enabling operation of the alignment isolation function performed by the station duty officer in step S2, sends the alignment isolation information between the car door and the platform door to the vehicle and platform door system; or the signal ATS system, based on the enabling operation of the de-alignment isolation function performed by the station duty officer in step S2, sends the alignment isolation information between the car door and the platform door to the vehicle and platform door system.

[0068] S4. Based on the enabling or disabling of the alignment isolation function performed by the station duty officer in step S2, the signal ATS system displays the alignment isolation enable status information on the ATS workstation, indicating to the station duty officer or dispatcher that the alignment isolation function is currently enabled or disabled.

[0069] S5. The vehicle and platform door system performs the corresponding alignment isolation function when the train stops and opens and closes the doors, based on the alignment isolation information provided by the signal ATS system in step S3, or performs the normal door opening and closing linkage function, without performing the alignment isolation function, based on the alignment isolation information not required by the signal ATS system.

[0070] As a preferred technical solution, when the enabling operation is performed by a control center dispatcher, the method includes the following steps:

[0071] A1. The control center dispatcher determines whether it is necessary to perform a position isolation enable (enable or stop) operation;

[0072] A2. When the alignment isolation function between train doors and platform doors is required, the dispatcher shall enable the alignment isolation function for a specific station or all stations along the line; when the alignment isolation function between train doors and platform doors is required to be bypassed or deactivated, the dispatcher shall deactivate the alignment isolation function for a specific station or all stations along the line.

[0073] A3. The signal ATS system, based on the enabling operation of the alignment isolation function performed by the dispatcher in step A2, sends the alignment isolation information between the car door and the platform door to the vehicle and platform door system; or the signal ATS system, based on the enabling operation of the disabling alignment isolation function performed by the dispatcher in step A2, sends the alignment isolation information between the car door and the platform door to the vehicle and platform door system.

[0074] A4. Based on the enabling operation of the alignment isolation function performed by the dispatcher in step A2, the signal ATS system will display the alignment isolation enabling status information on the ATS workstation, indicating to the station duty officer or dispatcher that the current alignment isolation function is enabled or disabled.

[0075] A5. The vehicle and platform door system performs the corresponding alignment isolation function when the train stops and opens and closes the doors, based on the alignment isolation information provided by the signal ATS system in step A3, or performs the normal door opening and closing linkage function, without performing the alignment isolation function, based on the alignment isolation information not required by the signal ATS system.

[0076] The above method can be simply summarized as follows: Addressing the shortcomings of the alignment isolation function and specific application scenarios, the signal ATS system identifies the operator's intention based on the relevant operations performed by station duty officers and control center dispatchers to enable alignment isolation between train doors and platform doors. It then performs logical judgment and determines whether alignment isolation is necessary based on the operation command to enable or disable alignment isolation. Figure 1 The system sends alignment and isolation instructions to the vehicle and platform door systems to ensure consistency in the alignment and isolation functions of the vehicles and platform doors, which greatly improves operational efficiency and ensures passenger safety when boarding and alighting.

[0077] This method enables the coordinated activation or deactivation of the signal system, vehicle, and platform door alignment isolation functions. It eliminates the need for maintenance personnel to manually inspect and troubleshoot, or to disable the alignment isolation function by disconnecting network communication links. This saves troubleshooting time, increases the project's automation level, and reduces personnel workload.

[0078] The above-mentioned method for automatic alignment isolation enabling based on the signal system has been successfully applied in Hangzhou Line 8 and the Airport Express Line, with good results. It has greatly improved the automation level of the project, reduced the troubleshooting pressure on maintenance personnel in emergency situations, and provided a flexible means of operation organization for station duty officers and dispatchers.

[0079] like Figure 1 The diagram shown illustrates the transmission of alignment isolation enable operation information in a signal ATS system according to one embodiment. Specifically:

[0080] The station HMI workstation serves as the human-machine interface for station operators, allowing them to configure the enabling or disabling of alignment isolation for a specific platform within the interlocking zone or the entire interlocking zone. The central MMI workstation serves as the human-machine interface for control center dispatchers, allowing them to configure the enabling or disabling of alignment isolation for a specific platform across the entire line or the entire line, and to send the relevant enabling or disabling information to the signal ATS server (for storage, logical operations, and forwarding to the interface system).

[0081] The signal ATS server performs logical operations based on the user's position isolation enable command, and then converts the command into a signal. Figure 1 The information for enabling or disabling alignment isolation is sent to the vehicle and platform door controllers.

[0082] After completing the relevant enabling operations, the human-machine interface of the station HMI workstation and the control center MMI workstation will display the alignment isolation enabling status.

[0083] After receiving the corresponding alignment and isolation information, the train will execute the alignment and isolation linkage to open and close the doors after the train has come to a complete stop at the station.

[0084] The platform door system's platform door controller receives the corresponding alignment and isolation information and sends the information to the corresponding platform door execution unit on the platform. After the train arrives at the station and comes to a complete stop, it executes the alignment and isolation linkage to open and close the platform door in conjunction with the door opening and closing command.

[0085] like Figure 2 As shown, this embodiment discloses a method flow for enabling position isolation in a signal ATS system, including the following steps:

[0086] Step 1: The station duty officer or control center dispatcher determines the circumstances under which positioning isolation is required;

[0087] Step 2: Based on the confirmation of the position isolation enable usage in Step 1, the station duty officer or dispatcher determines whether the position isolation function needs to be executed at this time, and sets the position isolation enable operation; if the station determines that the position isolation function does not need to be executed at this time, the position isolation enable operation is set to be stopped.

[0088] Step 3: Based on the alignment isolation enable operation in Step 2, the signal ATS system sends the calculated alignment isolation information to the vehicle and platform screen door systems, and the ATS HMI displays the alignment isolation enable status. Alternatively, based on the alignment isolation enable deactivation operation in Step 2, the signal ATS system sends the calculated alignment isolation information to the vehicle and platform screen door systems, and the ATS HMI displays the alignment isolation enable status.

[0089] Step 4: Based on the enabling or disabling operation of the alignment isolation function performed by the station duty officer or dispatcher, the signal ATS system displays the alignment isolation enabling status information on the ATS workstation, indicating to the station duty officer or dispatcher whether the alignment isolation function is currently enabled or disabled.

[0090] Step 5: When the vehicle and platform screen door system receives a signal system command indicating that alignment isolation is required, the alignment isolation function between the vehicle doors and platform screen doors is executed when the train stops at the platform to open and close the doors. Faulty vehicle doors or platform screen doors will not be linked to the opening and closing mechanism. In another scenario, when the vehicle and platform screen door system receives a signal system command indicating that alignment isolation is not required, the opening and closing mechanism between the vehicle doors and platform screen doors is executed when the train stops at the platform to open and close the doors.

[0091] This invention can quickly enable the alignment and isolation of platform doors and train doors, and immediately display the alignment and isolation status to station duty officers and dispatchers so that manual intervention can be carried out in special circumstances to prevent the alignment and isolation function from failing due to malfunction.

[0092] This invention adds a function to enable alignment isolation between train doors and platform screen doors through the signal ATS system, providing users with an operational method to enable or disable the alignment isolation function under special circumstances as needed. This method avoids situations where the alignment isolation function is erroneously activated due to software errors or hardware failures in the platform screen door system or the vehicle itself.

[0093] This invention provides an emergency response method for station duty officers and control center dispatchers through the signal ATS system, avoiding operational delays caused by waiting for maintenance personnel to handle alignment and isolation function failures during operation. This helps improve the level of operational service and reduce the workload of operation and maintenance personnel.

[0094] During the construction of urban rail transit, the installation and commissioning of platform screen door systems and vehicles often cannot be guaranteed to proceed synchronously. If the installation and commissioning of platform screen doors are delayed, the alignment isolation function may not be ready for operation, resulting in incomplete alignment isolation function commissioning for individual platform screen doors or entire sides of platform screen doors. To avoid confusion with the vehicle door alignment isolation function, it is usually necessary to disable the alignment isolation function between the platform screen doors and vehicle doors until the interface function is fully commissioned before enabling it. This invention allows users to flexibly choose to enable or disable the alignment isolation function, providing an effective operational organization method for determining whether to use the alignment isolation function during line construction trial operation or later passenger operation.

[0095] The electronic device of this invention includes a central processing unit (CPU), which can perform various appropriate actions and processes according to computer program instructions stored in read-only memory (ROM) or loaded from a storage unit into random access memory (RAM). The RAM may also store various programs and data required for device operation. The CPU, ROM, and RAM are interconnected via a bus. Input / output (I / O) interfaces are also connected to the bus.

[0096] Multiple components in the device are connected to the I / O interface, including: input units such as keyboards and mice; output units such as various types of displays and speakers; storage units such as disks and optical discs; and communication units such as network interface cards (NICs), modems, and wireless transceivers. The communication unit allows the device to exchange information / data with other devices through computer networks such as the Internet and / or various telecommunications networks.

[0097] The processing unit executes the various methods and processes described above, such as methods S1-S5, A1-A5. For example, in some embodiments, methods S1-S5, A1-A5 may be implemented as computer software programs tangibly contained in a machine-readable medium, such as a storage unit. In some embodiments, part or all of the computer program may be loaded and / or installed on the device via ROM and / or a communication unit. When the computer program is loaded into RAM and executed by the CPU, one or more steps of methods S1-S5, A1-A5 described above may be performed. Alternatively, in other embodiments, the CPU may be configured to execute methods S1-S5, A1-A5 by any other suitable means (e.g., by means of firmware).

[0098] The functions described above in this document can be performed, at least in part, by one or more hardware logic components. For example, exemplary types of hardware logic components that can be used, without limitation, include: Field Programmable Gate Arrays (FPGAs), Application-Specific Integrated Circuits (ASICs), Application Standard Products (ASSPs), System-on-Chip (SoCs), Complex Programmable Logic Devices (CPLDs), and so on.

[0099] The program code used to implement the methods of the present invention can be written in any combination of one or more programming languages. This program code can be provided to a processor or controller of a general-purpose computer, special-purpose computer, or other programmable data processing device, such that when executed by the processor or controller, the program code causes the functions / operations specified in the flowcharts and / or block diagrams to be implemented.

Claims

1. A method for enabling positional isolation based on a signal system, characterized in that, This method involves a signal ATS system, vehicles, and platform screen door systems. The signal ATS system identifies the operator's intentions and determines whether alignment isolation is required based on the operation command to enable or disable alignment isolation. It then sends the corresponding command to the vehicle and platform screen door systems to enable alignment isolation for the vehicle and platform screen doors. The method includes two scenarios: enabling operation performed by station duty personnel and enabling operation performed by control center dispatchers. When the enabling operation is performed by the station duty officer, the method includes the following steps: S1. The station duty officer determines whether an alignment isolation enabling operation is required. S2. When the alignment isolation function between train doors and platform doors is required, the station duty officer shall enable the alignment isolation function for a specific station or all stations in this interlocking zone; when bypassing or stopping the alignment isolation function between train doors and platform doors is required, the station duty officer shall disable the alignment isolation function. S3. The signal ATS system, based on the enabling operation of the alignment isolation function performed by the station duty officer in step S2, sends the alignment isolation information between the car door and the platform door to the vehicle and platform door system; or the signal ATS system, based on the enabling operation of the de-alignment isolation function performed by the station duty officer in step S2, sends the alignment isolation information between the car door and the platform door to the vehicle and platform door system. S4. Based on the enabling or disabling of the alignment isolation function performed by the station duty officer in step S2, the signal ATS system displays the alignment isolation enable status information on the ATS workstation, indicating to the station duty officer or dispatcher that the alignment isolation function is currently enabled or disabled. S5. The vehicle and platform door system performs the corresponding alignment isolation function when the train stops and opens and closes the doors according to the alignment isolation information provided by the signal ATS system in step S3, or does not perform the alignment isolation function when the train stops and opens and closes the doors according to the alignment isolation information provided by the signal ATS system, and performs the normal door opening and closing linkage function. When the enabling operation is performed by a control center dispatcher, the method includes the following steps: A1. The control center dispatcher determines whether a position isolation enabling operation is required. A2. When the alignment isolation function between train doors and platform doors is required, the dispatcher shall enable the alignment isolation function for a specific station or all stations along the line; when the alignment isolation function between train doors and platform doors is required to be bypassed or deactivated, the dispatcher shall deactivate the alignment isolation function for a specific station or all stations along the line. A3. The signal ATS system, based on the enabling operation of the alignment isolation function performed by the dispatcher in step A2, sends the alignment isolation information between the car door and the platform door to the vehicle and platform door system; or the signal ATS system, based on the enabling operation of the disabling alignment isolation function performed by the dispatcher in step A2, sends the alignment isolation information between the car door and the platform door to the vehicle and platform door system. A4. Based on the enabling or disabling of the alignment isolation function performed by the dispatcher in step A2, the signal ATS system will display the alignment isolation enable status information on the ATS workstation, indicating to the station duty officer or dispatcher that the alignment isolation function is currently enabled or disabled. A5. The vehicle and platform door system performs the corresponding alignment isolation function when the train stops and opens and closes the doors, based on the alignment isolation information provided by the signal ATS system in step A3, or performs the normal door opening and closing linkage function, without performing the alignment isolation function, based on the alignment isolation information not required by the signal ATS system.

2. The method for enabling position isolation based on a signal system according to claim 1, characterized in that, The signal ATS system communicates with the platform door system and the vehicle, sending the required platform door alignment and isolation information to the platform door system and the required vehicle door alignment and isolation information to the vehicle. The signal ATS system enables or disables the alignment isolation function of the train doors and platform doors of the entire line or a certain station based on the operation intention of the station duty officer or dispatcher. Through logical operations, it forwards the alignment isolation instruction consistent with the dispatch operation intention to the train and platform door system.

3. The method for enabling position isolation based on a signal system according to claim 2, characterized in that, The interface protocol for communication between the signal ATS system and the platform screen door system defines the meaning of the states: state 1 means that no platform screen door alignment and isolation information is required, and state 2 means that platform screen door alignment and isolation information is required.
