Technical Field

[0001] This application relates to the field of grounding control technology for rail transit, and in particular to a remote-local integrated method and device for preventing misoperation control. Background Technology

[0002] With the increasing frequency and expansion of visualized grounding operations and rail transit maintenance, the rail transit sector is facing more advanced requirements for operations involving grounding and equipment power supply / deactivation. Current operating methods primarily consist of two approaches: visualized remote control and local manual operation. However, both of these methods are relatively isolated.

[0003] With the continuous expansion of urban subway networks, the existing two independent operating methods are insufficient to meet the management needs of more lines, and safety is also difficult to guarantee. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a remote-local integrated anti-misoperation control method. By setting up multiple combined control methods, including invoice tracking execution, remote control, and local control, it adapts to the security requirements of different scenarios.

[0005] The first aspect of this application provides a remote-to-local integrated anti-misoperation control method applied to a rail transit visual grounding system. The rail transit visual grounding system includes an operation ticket tracking execution device and a remote-controlled interlocking device, a comprehensive monitoring device, and a computer key, all connected to the operation ticket tracking execution device. The comprehensive monitoring device and the computer key are used for grounding control of the operating equipment. The method includes: The final operation control method for the operating equipment is determined, wherein the final operation control method includes a single local execution method, a local execution method with remote control switching, a single remote control method, or a remote control method with local execution switching. If the final operation control method is the single remote control method or the local execution switching remote control method, then the operation ticket tracking execution device tracks and collects the equipment information of each operating device when the operation ticket is executed, and performs anti-misoperation verification based on the equipment information of each operating device; according to the result of the anti-misoperation verification, the remote control interlocking device is controlled to lock and unlock, and according to the result of the lock and unlocking, the integrated monitoring device is remotely controlled to perform grounding operation on each operating device based on the operation ticket. If the final operation control method is the single local execution method or the local execution method with remote control switching, then the computer key is used to perform grounding operations on each operating device based on the operation ticket.

[0006] In one optional embodiment, the step of tracking and collecting equipment information of each operating device during the execution of the operation ticket through the operation ticket tracking and execution device, and performing error prevention verification based on the equipment information of each operating device, includes: The operation ticket tracking and execution device tracks the operating status of each operating device when the operation ticket is executed, and periodically collects the real-time operating status of the operating device being operated. Based on the error prevention logic of the operating equipment, the real-time operating status is checked to obtain the check result.

[0007] In an optional embodiment, the step of tracking and collecting equipment information of each operating device during the execution of the operation ticket through the operation ticket tracking and execution device, and performing error prevention verification based on the equipment information of each operating device, further includes: During the periodic verification process to prevent errors, the real-time operating status of the operating equipment is monitored. Alternatively, it can detect in real time whether there are any sudden changes in the operating status of the equipment being operated or related equipment. Based on the error prevention logic of the operating equipment, the real-time operating status or the operating status after a sudden change of the operating equipment is checked to obtain the check result.

[0008] In an optional implementation, the step of controlling the locking / unlocking of the remote interlocking device based on the anti-misoperation verification result, and controlling the grounding operation of each operating device by the integrated monitoring device based on the operation ticket according to the locking / unlocking result and the remote control method, includes: If the anti-misoperation verification result is passed, the unlocking / locking message returned by the computer key is received, and the remote locking / locking operation is performed on the remote locking / locking device based on the unlocking / locking message. After the remote locking device completes the locking and unlocking operation, the integrated monitoring device performs a grounding operation on the operating equipment based on the operation ticket; If the error prevention verification fails, the remote control interlocking device will be locked, and the integrated monitoring device will be prohibited from authorizing grounding operations.

[0009] In an alternative implementation, before determining the final operation control method for the operating device, the method further includes: In response to the invoicing operation for each operating device, an operating ticket is generated based on the operating ticket generation and tracking mechanism, and a simulated distribution is made to the operating ticket tracking execution device and / or the computer key, wherein the operating ticket is used for the grounding operation of the operating device.

[0010] In one alternative implementation, prior to determining the final operation control method for the operating device, the following is included: In response to the setting operation of the operation control mode for the operating device, the initial operation control mode is determined, wherein the initial operation control mode is either remote control mode or local execution mode; Before performing a grounding operation on the operating equipment based on the operation ticket, it is detected whether the operation control mode switching operation has occurred.

[0011] In one optional implementation, determining the final operation control method for the operating device includes: If a switching operation is detected and the initial operation control mode is the local execution mode, then the final operation control mode is determined to be the remote control mode with local execution switching; otherwise, the final operation control mode is determined to be the single local execution mode. If a switching operation is detected and the initial operation control mode is the remote control mode, then the final operation control mode is determined to be the local execution mode with remote control switching; otherwise, the final operation control mode is determined to be the single remote control mode.

[0012] In an optional implementation, the step of controlling the locking / unlocking of the remote control interlocking device based on the anti-misoperation verification result, and remotely controlling the grounding operation of each operating device based on the operation ticket of the integrated monitoring device according to the locking / unlocking result, includes: If the anti-misoperation verification result is passed, then it is determined whether the remote locking device is unlocked. If it is not unlocked, an unlocking command is issued to unlock the remote locking device. The system issues an authorization response message to authorize the integrated monitoring device to perform grounding operations and controls the integrated monitoring device to perform grounding operations on the operating equipment based on the operation ticket. If the error prevention verification fails, the remote control interlocking device will be locked, and the integrated monitoring device will be prohibited from authorizing grounding operations.

[0013] In an optional implementation, after issuing the authorization response message to authorize the grounding operation of the integrated monitoring device and controlling the integrated monitoring device to perform grounding operation on the operating equipment based on the operation ticket, the method further includes: In response to the automatic unlocking operation of the integrated monitoring device, the integrated monitoring device is controlled to operate in the timeout automatic unlocking mode; The integrated monitoring device responds to the unlocking grounding control sent by the operation ticket tracking execution device by automatically unlocking after a timeout.

[0014] In an optional implementation, the rail transit visual grounding system further includes multiple client-side and station-level anti-misoperation subsystems; the method further includes: Based on multi-level and multi-authority authorization, the plurality of clients, the station-level anti-misoperation subsystem and the integrated monitoring device perform grounding operation and monitoring on each operating device.

[0015] A second aspect of the present application provides a visual grounding control device for rail transit, applied to a visual grounding system for rail transit, characterized in that the visual grounding system for rail transit comprises an operation ticket tracking and executing device, and a remote control locking device, an integrated monitoring device and a computer key respectively connected to the operation ticket tracking and executing device, wherein the integrated monitoring device and the computer key are configured for grounding control of operating devices; the device comprises: a determination module, configured to determine a final operation control mode for an operating device, wherein the final operation control mode comprises a single local execution mode, a local execution mode switched from remote control, a single remote control mode or a remote control mode switched from local execution; a checking module, configured to, when the final operation control mode is the single remote control mode or the remote control mode switched from local execution, track and collect device information of each operating device when the operation ticket is executed through the operation ticket tracking and executing device, and perform anti-misoperation checking based on the device information of each operating device; a control module, configured to control unlocking and locking of the remote control locking device according to a result of the anti-misoperation checking, remotely control the integrated monitoring device to perform grounding operation on each operating device based on the operation ticket according to an unlocking and locking result; and when the final operation control mode is the single local execution mode or the local execution mode switched from remote control, perform grounding operation on each operating device based on the operation ticket through the computer key.

[0016] In the technical solution provided by the present application, by setting a variety of combined control modes including ticket issuing tracking execution, remote control and local control, compatibility with safety requirements of different scenarios is achieved, and meanwhile, simultaneous use of multiple control modes also improves operation and maintenance efficiency; by introducing authorized anti-misoperation checking, misoperation caused by wrong state judgment or unsatisfied conditions is effectively avoided, operation safety of the overall system is improved, and meanwhile, linkage control between the operation ticket and the integrated monitoring device is realized, which supports simulation before operation and real-time state checking, and ensures that each step of operation conforms to logical sequence and safety requirements.

Detailed Implementation

[0018] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms “comprising” or “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0019] Currently, in the field of power outage and restoration operations in rail transit systems, there are two main traditional methods for operations involving grounding and equipment power outage and restoration: visual remote control operation and manual on-site operation using a computer key. Although these methods can achieve safe operation and prevent misoperation, they cannot achieve control in interconnected scenarios.

[0020] Based on this, this application combines three methods—operation ticket tracking, remote control, and local operation—and introduces real-time error prevention authorization operation. This approach achieves integrated monitoring and linkage of central, station, and local levels, and is compatible with operations in any scenario.

[0021] Please see Figure 1This application provides an embodiment of the remote-local integrated anti-misoperation control method provided in this application. The method is applied to a rail transit visual grounding system. The system includes an operation ticket tracking execution device and a remote control locking device, an integrated monitoring device, and a computer key respectively connected to the operation ticket tracking execution device. The integrated monitoring device and the computer key are used for grounding control of the operation equipment.

[0022] Based on this system, the method provided in this embodiment includes the following steps: S110, Determine the final operation control method for the operating equipment; It should be noted that the final operation control method includes a single local execution method, a local execution method with remote control switching, a single remote control method, or a remote control method with local execution switching.

[0023] The rail transit visualization grounding system is equipped with a user interface for operations such as ticketing, authorization, and settings. Operators can perform touch operations on the mode setting page within the user interface. The system sets the corresponding anti-misoperation mode based on the touch operation, which is to select the application mode required for the operation scenario by combining operation ticket tracking and execution with at least one operation control method. For example, the first anti-misoperation mode is operation ticket tracking and execution + integrated monitoring and remote control, and the second anti-misoperation mode is operation ticket tracking and execution + integrated monitoring and remote control + local execution.

[0024] Before or after determining the specific target grounding operation mode, the operator can also issue operation tickets for each operating device at the target work site by performing touch operations on the ticketing page in the user interface. Then, the simulation is started and uploaded to the operation ticket tracking and execution device, so that the operation ticket tracking and execution device can track each operating device when the operation ticket is executed.

[0025] S120, if the final operation control method is a single remote control method or a remote control method with local execution switching, the operation ticket tracking execution device tracks and collects the equipment information of each operating device when the operation ticket is executed, and performs anti-misoperation verification based on the equipment information of each operating device. In this embodiment, after determining the target grounding operation mode, the system's anti-misgrounding control path is determined according to the target grounding operation mode. If the target grounding operation mode is the first anti-misgrounding operation mode, the determined anti-misgrounding control path consists of the operation ticket tracking execution device, the remote control locking device, and the integrated monitoring device. If the target grounding operation mode is the second anti-misgrounding operation mode, the determined anti-misgrounding control path consists of the operation ticket tracking execution device, the computer key, the remote control locking device, and the integrated monitoring device.

[0026] When the target grounding operation mode is the second anti-misoperation mode, while the simulated operation ticket is uploaded to the operation ticket tracking and execution device, the operation ticket is also sent to the computer key. This allows the operator to carry the computer key to the site area where the operating equipment is located to confirm the status or unlock it. At the same time as confirmation or unlocking, the operation ticket tracking and execution device monitors and collects the corresponding operating status in real time, and reports and performs a complete anti-misoperation verification operation under the pre-set anti-misoperation verification trigger conditions.

[0027] In practical applications, it is specifically triggered by two mechanisms: timed control and mutation detection. That is to say, the rail transit visual grounding system is equipped with timed programs and mutation detection programs to track and collect and report the operating status of the operating equipment during the execution of the operation ticket. The tracking is real-time, and the collection and reporting is triggered by the defined program and the mutation detection program.

[0028] Understandably, after the operation ticket is simulated and uploaded to the operation ticket tracking and execution device and the computer key, the operation ticket tracking and execution device tracks the running status of each operation ticket being executed in real time and records it in the cache or a preset record table. After the timed program or the mutation detection program is triggered, the real-time running status of the operation ticket being executed is selected from the recorded data, reported, and checked for error prevention. The final error prevention check result is output, which includes two cases: check passed and check failed.

[0029] S130, based on the result of the anti-misoperation verification, controls the locking and unlocking of the remote control interlocking device, and based on the result of the locking and unlocking, the remote control integrated monitoring device performs grounding operations on each operating device based on the operation ticket.

[0030] In this embodiment, if the anti-misoperation verification result is passed, the process continues to unlock the remote control interlocking device and authorize the operation of the integrated monitoring device. This authorization can be layer-by-layer, meaning that remote control permissions for operating the equipment can be granted in real-time or as a one-time authorization. Furthermore, after authorization is granted, the integrated monitoring device issues a grounding command to control the grounding of the corresponding operating equipment.

[0031] If the error prevention check fails, the remote control interlocking device will be locked. At the same time, the integrated monitoring device will be prohibited from authorizing the operation of the equipment. This prohibition of authorization means that all operating permissions of the equipment will be prohibited at once.

[0032] S140, if the final operation control mode is a single local execution mode or a local execution mode with remote control switching, then the grounding operation of each operating device is performed by the computer key based on the operation ticket.

[0033] When grounding is performed using a computer key, specifically when the target grounding operation mode is the second anti-misoperation mode, the operator, after completing the grounding operation on the equipment using the computer key, reports the post-operation information to the system. Alternatively, the computer key can be used to switch to a comprehensive monitoring device for remote control.

[0034] In another implementation, when the final operation control mode is a single local execution mode, it should be understood that the mode setting of the operating equipment is local execution mode from the beginning. After the system issues the operation ticket, the operation ticket is directly simulated. After the simulation is complete, the computer key is issued. The staff carries the computer key to the site where the operating equipment is located for inspection. After the inspection is completed, the computer key is used to perform the on-site grounding operation of the operating equipment.

[0035] Similarly, if the final operation control method is a single remote control method, it should be understood that the mode setting of the operating equipment is remote control mode from the beginning. Then, after the system issues the operation ticket, it directly starts to simulate the operation ticket. After the simulation is complete, it is sent to the integrated control and monitoring device. At the same time, the operation ticket is also tracked in real time for anti-misoperation verification. After the anti-misoperation verification is passed, the remote control interlocking device is controlled to lock and unlock. Based on the lock and unlocking result and the remote control method, the integrated monitoring device is controlled to perform grounding operation on each operating device based on the operation ticket.

[0036] In addition, when the final operation control mode is either the local execution mode with remote control switching or the remote control mode with local execution switching, the determination of the final control operation mode should be understood as detecting whether a switching operation exists during the grounding operation of the operating equipment based on the initial operation control mode. That is, whether a command to switch to the local execution mode or the remote control mode is triggered. If so, the local execution mode or the remote control mode is determined based on the switching command, and then the grounding control of the operating equipment is based on the switched mode.

[0037] The remote-to-local integrated anti-misoperation control method provided in this embodiment, after determining whether the operation control mode is a single remote control mode or a remote control mode with local execution switching, performs anti-misoperation verification by tracking and collecting equipment information of the operating equipment during the execution of the operation ticket. Based on the result of the anti-misoperation verification, the remote control locking device is unlocked or locked. Finally, the grounding operation of the operating equipment is performed using an integrated monitoring device or a computer key. By introducing an operation ticket-based tracking mechanism, combined with real-time monitoring of the operation ticket execution device and an authorized anti-misoperation verification process, the entire grounding process of rail transit is visualized and automated. This not only significantly improves the safety and compliance of the operation process and prevents misoperation caused by abnormal status, but also supports real-time control and authorization of operation permissions by the remote monitoring system, enhancing the system's operating efficiency and responsiveness in multi-site, multi-level collaborative scenarios.

[0038] Please see Figure 2 This application provides another embodiment of the remote-to-local integrated anti-misoperation control method. The system includes an operation ticket tracking and execution device, a remote control locking device, a comprehensive monitoring device, and a computer key. It supports two settings and multiple combinations of anti-misoperation modes, and achieves safe and efficient execution of grounding operations through an authorized real-time anti-misoperation verification mechanism. Simultaneously, the system possesses closed-loop control for clearing and power supply, automatic unlocking and unattended operation capabilities, and a multi-level, multi-permission real-time monitoring mechanism. The method includes the following steps: S210, responding to the mode setting operation for each operating device, determines the initial operation control mode; In this embodiment, the initial operation control mode is either a single remote control mode or a single local execution mode; the specific operation process for setting the initial operation control mode is as follows: the operators of the rail transit visual grounding system set the target grounding operation mode of the system through the operation interface.

[0039] It should be noted that this initial operation control method actually includes: (1) Operation ticket tracking and execution + remote control mode; (2) Operation ticket tracking and execution + on-site execution method.

[0040] After the system responds to the setting operation, it determines the initial operation control mode and loads the anti-misoperation control logic and process corresponding to the mode. That is, it determines an integrated control path from the operation ticket tracking execution device, remote interlocking device, integrated monitoring device and computer key in the system, and executes the operation ticket under the path.

[0041] S220 responds to the invoicing operation for each operating device, generates an operation ticket based on the operation ticket generation and tracking mechanism, and simulates its distribution to the operation ticket tracking execution device and / or computer key.

[0042] In this embodiment, the operation ticket is used for grounding the operating equipment. Specifically, the rail transit visual grounding system is actually a rail transit visual grounding system, such as an OCC or station-level visual grounding system. The operator issues an operation ticket on the ticketing interface of the OCC or station-level visual grounding system, simulates the operation ticket, and then transmits the operation ticket to the operation ticket tracking and execution device and / or computer key.

[0043] It should be noted that after the operation ticket is simulated, the operation ticket is uploaded to the corresponding module according to the initial operation control method. If it is the operation ticket tracking and execution + remote control mode, it only needs to be uploaded to the operation ticket tracking and execution device. If it is the operation ticket tracking and execution + remote control + local execution mode, it is uploaded to both the operation ticket tracking and execution device and the computer key.

[0044] S230. The operation status of each operating device is tracked during the execution of the operation ticket through the operation ticket tracking execution device, and the real-time operation status of the operating device being operated is collected periodically or suddenly.

[0045] The real-time operating status of each operating device collected in this step refers to the real-time operating status of the currently executing operating device and the devices related to the currently executing operating device.

[0046] The data collection here includes two stages: recording and storage, and retrieval and reporting. The recording and storage stage involves tracking and collecting data at all times, while the retrieval and reporting stage involves reporting at regular intervals or triggered by sudden changes.

[0047] In another implementation, mutation detection is actually implemented during a timed process. Specifically, during the periodic anti-misoperation verification, the real-time operating status of the operating equipment is detected in real time. Alternatively, it can detect in real time whether there are any sudden changes in the operating status of the equipment being operated or related equipment. Based on the error prevention logic of the operating equipment, the real-time operating status or the operating status after a sudden change of the operating equipment is checked to obtain the check result.

[0048] In practical applications, timed reporting is achieved by setting a timer or a timed program, while sudden change-triggered reporting is achieved by setting real-time state change detection rules. These real-time state change detection rules mainly target whether the state of the relevant equipment of the operating device undergoes a sudden change. If so, the data is collected and reported; otherwise, the system waits for the timer to arrive.

[0049] S240 controls the grounding operation of the integrated monitoring device or the computer key based on the operation ticket of the operation equipment using the initial operation control method.

[0050] Specifically, if the initial operation control mode is a single remote control mode, the operation ticket tracking and execution device tracks and collects the equipment information of each operating device when the operation ticket is executed, and performs anti-misoperation verification based on the equipment information of each operating device; according to the result of the anti-misoperation verification, the remote control interlocking device is controlled to lock and unlock, and according to the result of the lock and unlocking, the integrated monitoring device is remotely controlled to perform grounding operation on each operating device based on the operation ticket. If the initial operation control mode is single local execution, then the grounding operation of each operating device is performed by the computer key based on the operation ticket.

[0051] Furthermore, the step of controlling the locking and unlocking of the remote interlocking device based on the anti-misoperation verification result, and remotely controlling the grounding operation of each operating device based on the operation ticket according to the locking and unlocking result, includes: If the anti-misoperation verification result is passed, then it is determined whether the remote locking device is unlocked. If it is not unlocked, an unlocking command is issued to unlock the remote locking device. The system issues an authorization response message to authorize the integrated monitoring device to perform grounding operations and controls the integrated monitoring device to perform grounding operations on the operating equipment based on the operation ticket. If the error prevention verification fails, the remote control interlocking device will be locked, and the integrated monitoring device will be prohibited from authorizing grounding operations.

[0052] S250 detects whether an operation control mode switching operation has occurred before performing grounding operation on the operating equipment based on the operation ticket.

[0053] S260, if a switching operation is detected and the initial operation control mode is the local execution mode, then the final operation control mode is determined to be the remote control mode with local execution switching.

[0054] S270 performs error prevention verification on the real-time operating status based on the error prevention logic of the operating equipment in operation, and obtains the verification result.

[0055] Understandably, the operation ticket tracking execution device periodically or in real time collects the operating status of key equipment (such as grounding switches, circuit breakers, access control systems, etc.), including whether there are any sudden changes in status.

[0056] The system verifies the current state based on error prevention logic rules, including two modes: periodic verification and emergency state verification. Periodic verification: Regularly check whether the equipment status meets the licensing conditions; Emergency verification: In the event of a sudden change in state or a change in associated conditions, a new judgment to prevent errors should be made immediately.

[0057] If the verification passes, the system authorizes the next step; if it fails, the control link is immediately locked and an alarm is issued, which means the remote control locking device is locked.

[0058] S280, based on the result of the anti-misoperation verification, controls the locking and unlocking of the remote control interlocking device, and based on the result of the locking and unlocking, the remote control integrated monitoring device performs grounding operations on each operating device based on the operation ticket.

[0059] Once the anti-misoperation verification is passed, the system initiates the grounding operation of the integrated monitoring device or the computer key. The specific procedures include: Send an unlock command to the remote locking device; Based on the selected target grounding operation mode, send an authorization response message to the integrated monitoring device to achieve remote grounding control; Alternatively, authorization can be granted to the on-site computer key, and on-site personnel can execute local control based on the feedback message from the computer key.

[0060] The system supports switching from remote control to local control, or from local control to remote control, ensuring efficient handling of complex on-site conditions.

[0061] like Figure 3 As shown, real-time error prevention is achieved by periodically collecting the real-time operating status of the equipment. Specifically, the operating equipment being tracked is verified. Based on the verification result, the remote control interlocking device is unlocked or locked. If the verification passes, the remote control interlocking device is unlocked, and if unlocked successfully, the integrated monitoring device is authorized to operate. Otherwise, the integrated monitoring device is authorized to disallow operation. If the verification fails, the remote control interlocking device is locked, and the integrated monitoring device is authorized to disallow operation. Scenario 2: Real-time error prevention is implemented for equipment operating in real-time based on sudden data acquisition. Specifically, when changes are detected in the logic-related equipment or other conditions of the tracked device, real-time error prevention verification and judgment are performed. Subsequent operations after the judgment result are the same as those for timed periodic control.

[0062] In this embodiment, if the target grounding operation mode is a combination of operation ticket tracking execution process and remote control mode, the step of controlling the locking and unlocking of the remote control interlocking device based on the anti-misoperation verification result, and the grounding operation of each operating device by the integrated monitoring device, includes: If the anti-misoperation verification result is passed, then it is determined whether the remote locking device is unlocked. If it is not unlocked, an unlocking command is issued to unlock the remote locking device. A permission response message is issued to authorize the grounding operation of the integrated monitoring device, so as to enable the grounding operation of the operating equipment; If the error prevention verification fails, the remote control interlocking device will be locked, and the integrated monitoring device will be prohibited from authorizing grounding operations.

[0063] like Figure 4 As shown, in an OCC or station-level visual grounding system, the operator issues an operation ticket, simulates the operation ticket, and then transmits the operation ticket to the operation ticket monitoring and execution device. The operation ticket monitoring and execution device then... Figure 3 The verification process employs authorized real-time error prevention verification. Once verification is successful, the integrated monitoring device can remotely operate the equipment. This control method achieves efficient, fast (no manual on-site operation required), and low-cost (lower equipment costs, no need for computer keys) control.

[0064] In this embodiment, if the target grounding operation mode is a combination of operation ticket tracking execution process, remote control mode, and local execution mode, the step of controlling the locking and unlocking of the remote control locking device based on the anti-misoperation verification result, and the grounding operation of each operating device by the integrated monitoring device and / or the computer key, includes: If the anti-misoperation verification result is passed, the unlocking / locking message returned by the computer key is received, and the remote locking / locking operation is performed on the remote locking / locking device based on the unlocking / locking message. After the remote locking device completes the locking and unlocking operation, the operating device is grounded using the computer key; If the error prevention verification fails, the remote control interlocking device will be locked, and the integrated monitoring device will be prohibited from authorizing grounding operations.

[0065] Furthermore, after the remote locking device completes the locking and unlocking operation, it also includes: If the remote control mode switching message is received from the computer key, an authorization response message is sent to authorize the grounding operation of the integrated monitoring device, so as to realize the grounding operation of the operating equipment.

[0066] like Figure 5 and 6As shown, in an OCC or station-level visual execution system, the operator issues an operation ticket, simulates the operation ticket, and then transmits the operation ticket to the computer key for execution. The operator, carrying the computer key, goes to the location of the operating equipment. After verifying that everything is in order, the local operator manually operates the computer key to control the operating equipment. Alternatively, if control via the computer key is not desired, the equipment can be remotely controlled by the OCC operator through a comprehensive monitoring device. After remote control operation, the equipment's status is uploaded, and the OCC operator can see the real-time operation status of the operation ticket. The local operator can check the execution result in real time. After the operation is completed, the next step is performed. If remote control execution via OCC is not possible, remote operation can be switched to manual operation. This mode is a double-confirmation mode with high security features.

[0067] S290, if a switching operation is detected and the initial operation control mode is remote control mode, then the final operation control mode is determined to be the local execution mode of remote control switching, and the grounding operation of each operating device is performed by the computer key based on the operation ticket.

[0068] In other words, switching from remote control to computer key operation can be understood as prompting and switching to local grounding of the operating equipment via the computer key when the integrated monitoring device is unable to complete the grounding operation of the operating equipment.

[0069] In another embodiment, after the operation ticket is executed, the method further includes: The computer key is inserted sequentially at each clearing point in the inspection site to confirm the clearing, and grounding is performed after all clearing points have been confirmed.

[0070] Once the maintenance work is completed, the system enters the power-on preparation phase. Operators must insert the computer key into each clearing point in sequence for confirmation; the system verifies the access control status and the key insertion action by judging the structure and logic, ensuring that there are no errors on site, and gradually unlocks the grounding permission; if personnel intrude or the access control status is abnormal during the clearing process, the system will automatically determine that the clearing has failed and must be re-executed; after successful clearing, the system automatically generates a clearing confirmation signal, allowing subsequent grounding operations to be completed in a closed loop.

[0071] like Figure 7As shown, when maintenance is completed and the platform needs to be powered on, a platform clearing process is required. This involves clearing the platform using a computer key before power is supplied. The system sends the platform door status to the system in real time. When the operator enters the maintenance platform from the maintenance entrance and reaches clearing point 1, they insert the computer key for confirmation. After confirmation, the system records a lock logic, indicating the start of the clearing process. If the maintenance entrance platform door opens at this time, and someone enters the clearing platform, the clearing process is invalid and must be restarted. When the operator reaches clearing point 2, a clearing completion confirmation is required. When the operator exits through the platform door, the system locks the clearing process, indicating that clearing is complete. If the entrance or exit platform door opens during this process, and the door status changes, the background system will determine that someone has entered, and the platform clearing will fail. If power is not supplied within a specified time (configurable) after the clearing process is completed, the clearing process is invalid and must be restarted. The system outputs a real-time AND logic based on the door and clearing point data, which is displayed as a clearing signal light in the system. Compared to traditional clearing, this method is simpler to operate, allowing clearing and power restoration to be initiated simultaneously on a single operation ticket. Through the operation ticket tracking system, operators can monitor the process remotely in real time, achieving perfect interconnection and interlocking between clearing and power restoration.

[0072] In another embodiment, after issuing the authorization response message to authorize the integrated monitoring device to perform a grounding operation, the method further includes: In response to the automatic unlocking operation of the integrated monitoring device, the integrated monitoring device is controlled to operate in the timeout automatic unlocking mode; The integrated monitoring device responds to the unlocking grounding control sent by the operation ticket tracking execution device by automatically unlocking after a timeout.

[0073] Understandably, when remote terminals such as OCC are unavailable or the system is unresponsive for an extended period, causing the remote locking device to time out and fail to unlock, the operation ticket tracking execution device automatically detects whether the remote locking status has timed out and triggers the automatic unlocking logic to ensure that the operation process is not interrupted and improves system stability and reliability.

[0074] When the entire operation process requires real-time tracking and verification, but manpower is insufficient, operators can issue tickets remotely at the OCC and then transmit the tickets for operation ticket tracking and execution. In an extreme case, if no one is monitoring the OCC, and the equipment is locked due to remote closing timeout, the integrated monitoring device cannot perform remote control operations. In this situation, the automatic unlocking function after timeout plays a crucial role. When the operation ticket tracking and execution device detects remote closing timeout and locking, it automatically issues an unlocking operation, ensuring the execution of remote control operations by the integrated monitoring device. Operators do not need to travel from the local end to the OCC to perform the unlocking operation.

[0075] exist Figure 8 In this system, "repeated remote control operation" can be automatically achieved without human intervention. This is particularly useful when the locations of the OCC, station-level system, and operating equipment are far apart and there is a shortage of manpower.

[0076] In another embodiment, the rail transit visual grounding system further includes multiple client-side and station-level anti-misoperation subsystems; the method further includes: The multiple clients, the station-level anti-misoperation subsystem, and the integrated monitoring device, based on multi-level and multi-permission authorization, perform grounding operations and monitoring on each operating device.

[0077] Understandably, the system supports multi-level permission linkage configuration between the OCC remote control center, station-level control terminals, and local operation terminals. Each terminal, based on the execution permissions set in the operation ticket, can perform monitoring, control, or confirmation operations on the equipment. For example, the OCC can remotely generate and manage operation tickets, station-level terminals can monitor and confirm local operations, and on-site personnel can execute actual control commands via computer keys. All permissions and actions are traceable, forming a closed-loop control system.

[0078] In this embodiment, an abnormal interruption and safety protection mechanism is also added during remote control: If the device status does not match the preset logic, or if an abnormality occurs during the verification process, the system will immediately suspend the current operation process. Relock the remote locking device; Further control operations by integrated monitoring devices or computer keys are prohibited. Alarms are sent synchronously to all monitoring terminals.

[0079] In this embodiment, the final operation control method for the operating equipment is determined. If the final operation control method is remote control, the equipment information of each operating device is tracked and collected by the operation ticket tracking execution device during the execution of the operation ticket, and anti-misoperation verification is performed based on the equipment information of each operating device. According to the result of the anti-misoperation verification, the remote locking device is controlled to lock and unlock. Based on the result of the locking and unlocking and the remote control method, the integrated monitoring device is controlled to perform grounding operations on each operating device based on the operation ticket. If the final operation control method is local execution, the grounding operations on each operating device are performed by a computer key based on the operation ticket. This achieves visualization, automation, and closed-loop control of the entire operation process of rail transit grounding equipment, ensuring the real-time performance, safety, and multi-dimensional monitoring and controllability of the equipment operation.

[0080] Furthermore, the method provided in this embodiment is not only applicable to the daily maintenance of the main line power supply system, but can also be widely applied to various rail transit power supply scenarios such as depots and station substations, and has good engineering adaptability and scalability.

[0083] In this embodiment, the verification module 920 is further used for: During the periodic verification process to prevent errors, the real-time operating status of the operating equipment is monitored.

[0087] In this embodiment, the determining module 910 is specifically used for: If a switching operation is detected and the initial operation control mode is the local execution mode, then the final operation control mode is determined to be the remote control mode with local execution switching; otherwise, the final operation control mode is determined to be the single local execution mode. If a switching operation is detected and the initial operation control mode is the remote control mode, then the final operation control mode is determined to be the local execution mode with remote control switching; otherwise, the final operation control mode is determined to be the single remote control mode.
