Description

Technical Field

[0001] The present invention relates to the field of intelligent management technology, and in particular to a system for completing sequence control through intelligent one-key operation. Background Art

[0002] With the development of modern power systems, the number and complexity of equipment in substations and power plants have increased significantly, and traditional manual switching operations have gradually exposed problems such as low efficiency and insufficient safety. In manual switching operations, each task usually involves a complex multi-step process, including receiving orders, writing tickets, reviewing, simulating, and actual execution. Taking the switching operation of a main transformer from "run to maintenance" as an example, the steps may be as many as 130 or more, requiring a lot of manpower and time investment. In addition, because the operation relies on manual execution and judgment, it is easily affected by human factors.

[0003] The prior art has the following deficiencies:

[0004] The current remote control means mainly adopt a distributed operation mode, that is, to issue instructions independently for each device or single task, lacking a unified operation logic and task coordination mechanism. This decentralized operation mode is inefficient when facing complex electrical equipment switching tasks, and it is easy to cause disconnection or omission of operation links. At the same time, due to the lack of a complete intelligent misoperation protection mechanism, the system cannot dynamically verify the correctness of the operation according to the operation logic, increasing the risk of human error. In addition, the existing video surveillance system has weak linkage with the operation platform, and cannot track the status of key equipment in real time or respond quickly to abnormal situations during operation, resulting in a lag in problem handling, further exacerbating operational risks. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent one-key operation system for completing sequential control, so as to solve the shortcomings of the background technology.

[0006] In order to achieve the above-mentioned object, the present invention provides the following technical solutions: a system for completing sequence control by intelligent one-key operation, comprising a sequence control module, a state confirmation module, a remote control module, a video linkage module, an intelligent error prevention module and a unified task management module;

[0007] The sequence control module is used to automatically complete the sequence operation of the circuit breaker, isolation switch and grounding switch according to the preset equipment operation logic and five-prevention and error-proofing rules, combined with the real-time status information of the current equipment, to ensure the safe switching of the equipment status during the operation;

[0008] The status confirmation module is integrated with the sequence control module to obtain the current operating status of the equipment before each operation is executed, and to confirm again whether the status change conforms to the expected logic after the operation is completed. If an abnormality occurs, an alarm and corrective measures are triggered immediately;

[0009] Remote control module, used for remote control of primary and secondary equipment, including circuit breakers, isolating switches, grounding switches, pressure plates, and circuit breakers;

[0010] The video linkage module is connected to the video surveillance system to provide real-time monitoring images of preset devices and automatically record and archive them at the operation node. When an abnormality is detected in the equipment, the video image is linked with the alarm prompt to assist the operator to quickly judge and take treatment measures;

[0011] Intelligent error prevention module, based on the five-prevention rules and the logical interlocking relationship between devices, dynamically verifies the safety of each operation instruction, and locks the instruction in real time when an operation error is found, and provides error prompts and correction suggestions to the operator;

[0012] The unified task management module is used to integrate the operation tasks of all equipment in the entire station, and generate a one-click task list based on the operation steps of multiple devices according to preset logical rules to avoid disconnection of operation links.

[0013] Preferably, the sequential control module adopts a hierarchical logic control architecture, including:

[0014] The first-level equipment control unit is used to directly face specific electrical equipment, realize equipment instruction execution, real-time operation status collection, fault self-detection and protection, and optimize the execution speed of operation instructions in combination with equipment action characteristics;

[0015] The secondary status monitoring unit is used to summarize and logically verify the status data uploaded by the primary equipment control unit, including operation instruction verification based on the five-defense rules, status synchronization confirmation, data redundancy verification, and equipment linkage action coordination;

[0016] The third-level task execution unit is used to break down the operation task into operation steps with a clear logical order, dynamically monitor the task execution process, handle status exceptions, and restore the device to a safe state through a rollback mechanism. At the same time, it records the operation data to optimize the future task execution logic.

[0017] Preferably, the state confirmation module is integrated with the sequence control module, specifically:

[0018] By collecting real-time status data of the target device and related devices, it is dynamically determined whether the device has the conditions to perform the next operation according to the five-defense rules and preset operation logic. If it does not meet the conditions, an alarm is triggered, the operation is blocked, and adjustment suggestions are prompted;

[0019] During the issuance and execution of operation instructions, the equipment status changes are monitored in real time, and the collected real-time data is compared with the expected status. If a timeout, anomaly or action deviation is detected, the operation process is stopped immediately, the abnormal information is fed back, and the subsequent operation plan is dynamically adjusted;

[0020] After the operation is completed, the final status of the equipment and its associated equipment is verified to ensure that the state switching conforms to the expected logic. If deviations are found, alarms are triggered and corrective measures are recommended. After confirming that all states are correct, an operation completion signal is generated and the next task is promoted.

[0021] Preferably, the remote control module is used to remotely control the primary device and the secondary device, specifically including:

[0022] Remote control operation of primary equipment: remote control of the opening and closing of the circuit breaker, combined with the status confirmation module to ensure the correctness of the operation logic, including the opening operation can only be performed after the load is transferred; provide real-time feedback information such as the opening and closing status of the circuit breaker, load current, and operation results; remotely operate the isolation switch, automatically check whether it meets the logical requirements of the operation after the circuit breaker is opened, and ensure that the mechanical state of the isolation switch operation is in place; realize the remote closing and disconnecting function of the grounding switch, combined with the five-prevention rules, ensure that the equipment is in a power-off state before operation to avoid erroneous operation with power on;

[0023] Remote control of secondary equipment: Provides remote control of the pressure plate, and is equipped with a status monitoring function to ensure that the pressure plate operates as expected; supports remote operation of the circuit breaker in the secondary circuit, real-time collection of the circuit breaker position status, and avoids misoperation; remotely operates the control switch and cooperates with the status confirmation module to ensure that the operation meets the logical interlocking requirements.

[0024] Preferably, the video linkage module is connected to a video surveillance system, specifically comprising:

[0025] Provides real-time monitoring screens of preset devices, and automatically switches the corresponding monitoring screen to the operator interface when the device enters the operation node; based on AI video analysis technology, automatically optimizes the clarity of the monitoring screen and highlights the area of ​​the target device; automatically starts recording 2 seconds before the start of the operation node and continues until 5 seconds after the operation is completed. If an abnormality is detected, the recording time is automatically extended and the abnormal location is marked; the video files are automatically classified and stored according to the operation task, time, and device name, and associated with the operation log for quick retrieval; uses compression algorithms to optimize storage efficiency and ensure that the image quality meets the playback requirements;

[0026] Integrates AI image recognition technology to analyze surveillance footage in real time and identify abnormal situations. If the video analysis does not match the device status, an abnormal alarm is triggered immediately and the abnormal area is marked. The real-time surveillance footage is displayed on the operator interface, and the abnormal area is highlighted. When an alarm is triggered, quick processing suggestions are provided.

[0027] Preferably, the intelligent error prevention module is integrated with the five-prevention rules and the logical interlocking relationship between the devices, specifically including:

[0028] The system collects the status data of all relevant equipment in real time, including the opening and closing status of the circuit breaker, the position of the isolation switch, the status of the grounding switch, and the voltage and current information of the line; based on the dynamic logic verification of the five-defense rules, according to the interlocking relationship between the equipment, it determines whether each operation instruction is consistent with the equipment operation logic; if the operation of equipment A depends on the completion status of equipment B, it verifies whether equipment B is in the expected state before the operation; when each instruction is executed, it dynamically detects the change of equipment status to verify whether it is executed according to the logic rules; if the equipment status does not change as expected, the system immediately stops the execution of the current instruction; if the equipment status does not match the operation logic, the exception handling mechanism is immediately triggered to synchronize the real-time status of the equipment with the logic verification result. If a conflict is found, an alarm is triggered and the operation is locked; when the system detects an operation instruction that violates the five-defense rules or logic interlocking, it immediately stops the issuance of the instruction; locks the relevant equipment to prevent the continued execution of the erroneous operation, enters the exception handling mode, and interrupts the subsequent operation logic.

[0029] Preferably, the unified task management module includes:

[0030] Receive the task objectives entered by the user and automatically decompose them into a series of equipment operation tasks according to the task objectives. The sequence control is integrated with the five-prevention rules:

[0031] According to the five-defense rules and preset sequential control logic, the task operation steps are sorted and dependency analyzed;

[0032] Arrange the integrated equipment operation tasks into a one-click task list, where each task contains information about the target equipment, operation type, and execution conditions;

[0033] During task execution, the system dynamically adjusts the task sequence based on real-time device status and operation results; if a step fails or is delayed, the execution conditions of subsequent tasks are re-evaluated, and the remaining tasks are executed first to reduce waiting time;

[0034] The task progress is tracked in real time and the status of each operation step is recorded. If a step fails, the subsequent task execution is suspended and an alarm is issued. If the risk of disconnection is detected, the system interrupts the task execution and prompts the operator.

[0035] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0036] 1. The present invention realizes the automatic coordination and intelligent verification of equipment operation by integrating sequential control, status confirmation, remote control, video linkage, intelligent error prevention and unified task management modules. With the help of the five-prevention rules and the logical interlocking relationship between devices, the system can dynamically verify the safety of each operation instruction, timely discover and correct operation errors, and effectively avoid human errors and operation conflicts. At the same time, the system supports automatic decomposition and sorting of tasks, and monitors the equipment status in real time to ensure the accuracy and safety of operations, greatly improving the efficiency and accuracy of operations.

[0037] 2. By introducing a video linkage module and combining it with AI video analysis technology, the present invention enables the system to monitor the status of key equipment in real time, automatically record and store videos during operation, and provide timely alarms and processing suggestions based on abnormal situations, further improving the abnormal response speed. In addition, the unified task management module can efficiently integrate the operation tasks of the entire station equipment, and by adjusting the task execution order and priority in real time, it minimizes the risk of disconnection and waiting time of the operation links. The efficient coordination and intelligent verification mechanism of the overall system effectively reduces operational risks, optimizes equipment operation strategies, and significantly improves the management efficiency and safety of power equipment.

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] For examples, see Figure 1 As shown, the system for completing sequence control with intelligent one-key operation described in this embodiment includes a sequence control module, a state confirmation module, a remote control module, a video linkage module, an intelligent error prevention module and a unified task management module;

[0042] The sequence control module is used to automatically complete the sequence operation of the circuit breaker, isolation switch and grounding switch according to the preset equipment operation logic and five-prevention and error-proofing rules, combined with the real-time status information of the current equipment, to ensure the safe switching of the equipment status during the operation;

[0043] The status confirmation module is integrated with the sequence control module to obtain the current operating status of the equipment before each operation is executed, and to confirm again whether the status change conforms to the expected logic after the operation is completed. If an abnormality occurs, an alarm and corrective measures are triggered immediately;

[0044] Remote control module, used for remote control of primary and secondary equipment, including circuit breakers, isolating switches, grounding switches, pressure plates, and circuit breakers;

[0045] The video linkage module is connected to the video surveillance system to provide real-time monitoring images of preset devices and automatically record and archive them at the operation node. When an abnormality is detected in the equipment, the video image is linked with the alarm prompt to assist the operator to quickly judge and take treatment measures;

[0046] Intelligent error prevention module, based on the five-prevention rules and the logical interlocking relationship between devices, dynamically verifies the safety of each operation instruction, and locks the instruction in real time when an operation error is found, and provides error prompts and correction suggestions to the operator;

[0047] The unified task management module is used to integrate the operation tasks of all equipment in the entire station, and generate a one-click task list based on the operation steps of multiple devices according to preset logical rules to avoid disconnection of operation links.

[0048] The sequential control module achieves efficient and safe management of complex electrical equipment operations by adopting a hierarchical logic control architecture. The architecture includes the following three main levels:

[0049] Level 1 equipment control unit: This layer is directly facing specific electrical equipment and is responsible for the basic operation functions and status management of a single device. Its main tasks include: Equipment instruction execution: Control the opening and closing actions of circuit breakers, isolating switches, grounding switches and other equipment according to the operation instructions; Equipment status acquisition: Real-time acquisition of equipment operation status (such as circuit breaker opening / closing, switch position, voltage, current, etc.), and upload the data to the upper module; Fault self-checking and protection: Real-time monitoring of the equipment operation status, immediately interrupting the operation and feeding back the alarm signal when an abnormality is found; Operation response optimization: Combined with the equipment type and action characteristics, optimize the execution speed of operation instructions to ensure that the equipment responds quickly and accurately.

[0050] Secondary status monitoring unit: This layer is responsible for summarizing, analyzing and verifying the status data uploaded by the primary equipment control unit to ensure that the operation logic between devices is correct. Its main tasks include: Logic rule verification: Based on the five-prevention rules and the preset sequential control logic, the operation instructions of the primary unit are verified to prevent misoperation or illegal operation; Status synchronization and confirmation: Compare the equipment status with the system target status to ensure that the actual result of each operation step meets the task plan; Data redundancy verification: Obtain status information from multiple sensors or data acquisition channels, and eliminate abnormal equipment status or transmission errors through cross-verification; Equipment linkage coordination: Coordinate the operation sequence and linkage actions of multiple devices according to the interlocking logic and operation requirements between devices.

[0051] Level 3 task execution unit: This layer is responsible for converting specific operation tasks into a series of equipment operation instructions arranged in a logical order, and monitoring and managing the entire process during task execution. Its main tasks include: task decomposition and scheduling: decomposing complex overall tasks into multiple equipment operation steps, and generating sequential instructions according to the priority and dependency of the equipment; full process monitoring: real-time monitoring of task execution progress, and dynamic adjustment of abnormal status or failures during the operation process; automatic recovery and rollback: if an abnormal state is detected during the operation, the system can automatically trigger the rollback mechanism to restore the equipment to a safe state; operation recording and optimization: record the data of each task execution, and optimize the sequential control logic by analyzing the task execution process to improve the execution efficiency of future tasks.

[0052] The three levels form a close collaborative working mechanism through real-time interaction of data and instructions: the first-level equipment control unit receives specific operation instructions from the third-level task execution unit and feeds back the execution results to the second-level status monitoring unit; the second-level status monitoring unit performs logical verification on the equipment status and sends the verification results to the third-level task execution unit to ensure the smooth progress of the task process; the third-level task execution unit adjusts the operation plan or triggers the fault handling mechanism based on the feedback from the second-level monitoring unit to ensure that the overall task is completed logically. Through this hierarchical architecture, the sequential control module can achieve comprehensive management of equipment operations, which not only improves operational efficiency, but also effectively reduces the risks caused by misoperation and abnormal conditions.

[0053] The status confirmation module is integrated with the sequential control module to obtain the current operating status of the equipment before each operation is executed, and to reconfirm whether the status change conforms to the expected logic after the operation is completed. If an abnormality occurs, an alarm and corrective measures are triggered immediately.

[0054] Before executing each operation, the status confirmation module collects real-time data from the equipment to conduct a comprehensive check on the current operating status of the equipment. Read the real-time status information of the target equipment (such as the circuit breaker open / close position, the isolation switch position, the grounding switch status, voltage, current, etc.). Obtain the status information of the associated equipment (such as the upper power supply status, the downstream load status). According to the five-prevention rules and the preset operation logic, determine whether the current equipment status allows the next operation to be performed. For example: before the circuit breaker is disconnected, it is forbidden to operate the isolation switch; before the grounding switch is disconnected, it is forbidden to close the circuit breaker. If the status does not meet the rules, an alarm is triggered and the operation is blocked, prompting the operator to make adjustments. Confirm that the equipment has the physical conditions and safety environment to execute the current instructions (such as the equipment is in a non-fault state and the operation command channel is unobstructed). Generate an operation permission signal to authorize the sequence control module to issue an operation instruction.

[0055] During the process of issuing and executing the operation instructions, the status confirmation module tracks the action status of the equipment in real time. Continuously monitor the status signals of the target equipment (such as changes in the opening and closing positions of the equipment, dynamic changes in voltage and current). Compare the real-time data with the expected action process to determine whether the equipment action is performed as expected. If no state change is detected within the specified time (such as the circuit breaker fails to open), trigger a timeout alarm and interrupt the current operation process. If an abnormal change is detected (such as the circuit breaker is mis-opened or the isolation switch position is abnormal), immediately stop subsequent operations and feedback abnormal information. Feedback the monitoring data to the sequential control module in real time to assist it in dynamically adjusting the subsequent operation logic.

[0056] After the operation is completed, the status confirmation module verifies the final status of the equipment to ensure that the status switching is successful and in line with the expected logic. Detect the final status of the target equipment (such as the circuit breaker has been opened, the isolation switch has been disconnected, etc.) and compare it with the expected status. Check whether the status of the associated equipment is consistent with the expected logic (such as whether the grounding switch has been closed after the operation is completed, and whether the downstream load has been powered off). If it is found that the equipment status is inconsistent with expectations (such as the circuit breaker fails to open), an abnormal alarm is triggered and corrective measures are recommended (such as sending the operation instruction again or manual intervention). After confirming that the status of the equipment and associated equipment are correct, an "operation completed" signal is generated, and the operation results and related data are recorded. Feedback the operation completion status to the sequential control module to promote the next task execution.

[0057] If an abnormality is detected at any stage (before, during, or after an operation), the status confirmation module will: immediately stop the current task; send an alarm to the operator and the system; and provide a description of the abnormal situation and possible solutions.

[0058] The remote control module is used to remotely control primary and secondary equipment, including circuit breakers, isolating switches, grounding switches, pressure plates, and circuit breakers.

[0059] Remote control operation of primary equipment includes: remotely realize the opening and closing control of the circuit breaker; combined with the status confirmation module, ensure that the circuit breaker status conforms to the operation logic (such as opening only after load transfer). Provide real-time status feedback function, including circuit breaker opening / closing status, load current, operation results and other information. Support remote opening and closing operation of the isolation switch, automatically check whether it meets the logical requirements of operation after the circuit breaker is opened; detect the mechanical state and position state of the equipment to ensure that subsequent operations are allowed only after the action is in place. Realize the remote closing and disconnecting function of the grounding switch; link with the five-protection rules to ensure that the equipment is in a power-off state before the grounding switch is operated to avoid erroneous operation with power on.

[0060] Remote control operation of secondary equipment includes: providing remote control of the pressure plate in the protection device; equipped with pressure plate status monitoring function to ensure that the pressure plate action meets expectations (such as the pressure plate should be completed before the protection is put into operation). Support the operation of the air breaker in the secondary circuit, including remote operation or disconnection function; real-time acquisition of the position status of the air breaker to avoid interruption of the secondary circuit due to misoperation. Used for remote control of control switches (such as knife switch operation switch, operation power switch); cooperate with the status confirmation module to ensure that the switch action meets the requirements of logical interlocking.

[0061] The remote control operation safety mechanism includes: through the user authority management system, the operation authority of operators of different levels is graded to ensure that only authorized personnel can perform specific operations. Before each operation, the remote control module will automatically check according to the operation logic and equipment status to prevent illegal operations (such as prohibiting the circuit breaker from opening when the load is not transferred). During the operation, the status data of the target device (such as the position of the knife switch, the status of the circuit breaker, etc.) is collected in real time and fed back to the operation terminal; if an abnormal status is detected (such as operation failure or equipment is not in place), the task will be stopped immediately and an alarm will be issued.

[0062] Provide operation step guidance based on the interlocking relationship between devices to ensure that users operate in the correct order. Automatically record detailed logs of each remote control operation, including operator, time, device status, command execution results, etc., for easy traceability and analysis. Support cross-device and cross-circuit linkage operations (such as automatic control of associated switches after completing circuit breaker opening); provide batch operation functions for efficient implementation of large-scale tasks (such as power outages or power restoration of the entire station). Connect the control terminals of primary and secondary devices through optical fiber, Ethernet or wireless communication; use high-reliability protocols (such as IEC 61850) to achieve data transmission and command issuance. Support docking with other systems (such as centralized control center, one-button sequential control system), reserve remote interfaces, and realize centralized control.

[0063] The video linkage module is connected to the video surveillance system to provide real-time monitoring images of preset equipment and automatically record and archive them at the operation node. When equipment abnormalities are detected, the video images are linked with alarm prompts to assist operators in making quick judgments and taking treatment measures.

[0064] By integrating with the equipment status monitoring module, the status information of the target equipment (such as circuit breakers, isolating switches, and grounding switches) can be obtained in real time; when the equipment enters a key operation node (such as switch opening and closing, circuit breaker switching), the corresponding monitoring screen is automatically switched to the operator interface.

[0065] Based on AI video analysis technology, the clarity of the monitoring screen is automatically optimized to highlight the key areas of the target equipment (such as the contact points of the knife switch or the opening and closing positions of the circuit breaker). Using multi-angle cameras, multi-view images are automatically synthesized during key operations to provide more comprehensive visual support for operations. Trigger conditions are generated according to preset key operation nodes (such as circuit breaker opening, isolation knife switch switching), and recording is started 2 seconds before the operation starts and lasts until 5 seconds after the operation is completed; if an abnormal state is detected (such as equipment operation failure or abnormal state), the recording time is automatically extended and the abnormal position is marked for subsequent analysis. The video files are automatically classified and stored according to the operation task, time, and device name, and the operation log is associated for quick retrieval. Compression algorithms are used to optimize storage efficiency while ensuring that the image quality meets playback requirements.

[0066] The video linkage module integrates AI image recognition technology, and identifies abnormal conditions (such as burnout of equipment contact points, inadequate knife switches, blocked circuit breakers, etc.) through real-time analysis of monitoring images. When the video analysis does not match the equipment status, it immediately triggers an abnormal alarm and marks the abnormal area in the image. The video abnormality information is linked to the status alarm system, and the real-time monitoring screen pops up on the operator interface, with red frames or highlights to display abnormal areas. When the alarm is triggered, quick processing suggestions are provided (such as resending operating instructions or switching to backup equipment after confirming the fault).

[0067] Real-time equipment operating parameters (such as voltage, current, and equipment open / close position) are superimposed on the monitoring screen to help operators intuitively judge the operating status; when an abnormality is found, the equipment status is marked with different colors or icons to quickly distinguish between normal and abnormal situations.

[0068] When an abnormal situation occurs, the system automatically generates a report containing the following contents: abnormal video clips (automatically cutting out the 5-second video before and after the abnormal situation); operating status parameters of abnormal equipment; abnormal description and handling suggestions of video analysis. The report is automatically uploaded to the operation record library for further review by operation and maintenance personnel.

[0069] When operating multiple devices at one time, the system automatically displays the corresponding screen of each device on the monitoring interface and marks the operating status of each device; when a device triggers an abnormality, its screen is placed on the main screen and remains highlighted until the processing is completed.

[0070] It provides a real-time monitoring panoramic view of all station equipment and supports one-click switching to the monitoring screen of a certain task equipment; in emergency situations (such as main transformer failure), it automatically switches to the monitoring screen of related equipment and locks the recording function to record the entire process.

[0071] The comparison function between operation logs and video images helps operators review operation steps and find possible errors or improvement points. AI assists in analyzing the operation characteristics of equipment during operation and optimizes subsequent sequential control logic. Typical operation and abnormal video data are imported into the training system as training cases to improve the emergency response capabilities of operators.

[0072] The intelligent error prevention module dynamically verifies the safety of each operation instruction based on the five-prevention rules and the logical interlocking relationship between devices. When an operation error is found, it locks the instruction in real time and provides error prompts and correction suggestions to the operator.

[0073] The system collects the current status of all relevant equipment in real time, including the opening and closing status of the circuit breaker, the position of the isolation switch, the status of the grounding switch, and the voltage and current information of the line, etc. The equipment status information is verified through high-frequency sampling and redundant channels to ensure data accuracy and reliability.

[0074] Logical verification based on the five-prevention rules: Rule 1: Prevent the circuit breaker from being opened or closed by mistake. Verify whether the conditions for opening and closing are met, such as whether the line load has been transferred and whether the protection device is correctly thrown in or out. Rule 2: Prevent the disconnector from being pulled in and out with load to confirm whether the circuit breaker has been opened and whether there is no current on the load side. Rule 3: Prevent the grounding wire from being hung with power on. Check whether the conditions such as circuit breaker opening and disconnection of the disconnector are met before operating the grounding switch. Rule 4: Prevent the voltage signal of the target interval from being accidentally entered into with power on to confirm whether there is no power at all. Rule 5: Prevent the misoperation of other associated equipment. Verify the status of other associated equipment according to the operation plan to ensure that it is not interfered with or affected by this operation.

[0075] Based on the interlocking relationship between devices, determine whether the instruction is consistent with the device operation logic. For example, if the operation of device A depends on the completion status of device B, verify whether device B is in the expected state before operation. Determine whether the sequence in the sequential control logic is correct, for example, first open the circuit breaker and then operate the isolation switch.

[0076] When each instruction is executed, the device status changes are dynamically detected to verify whether it is carried out according to the logic rules: if the status is not changed as expected (such as the knife switch is not closed according to the logic), the execution of the current instruction is stopped immediately; if the device status is detected to be inconsistent with the operation logic, the exception handling mechanism is triggered immediately. The real-time status of the device is synchronized with the logic verification result. If a conflict is found (such as the isolation knife switch is in the open state but the load current is detected), an alarm is triggered immediately and the operation is locked.

[0077] When an operation instruction that violates the "five prevention" rules or logical interlock is detected, the system will immediately: stop issuing the instruction; lock the corresponding device to prevent the erroneous operation from continuing; interrupt subsequent operation logic and enter exception handling mode.

[0078] After locking the command, the system provides clear prompts to the operator through the operation interface, including: the cause of the error (such as "the grounding switch cannot be closed in the energized state"); the wrong equipment status (such as "equipment X is still in the open state"); the violated rules (such as "five-prevention rules: it is forbidden to pull the isolation switch with load").

[0079] The system generates feasible corrective suggestions, such as prompting operators to complete load transfer before opening the switch; and suggesting checking the status of related equipment and trying again. When providing suggestions, the system marks abnormal equipment through a visual interface, intuitively displaying its operating status and conflict points with the operation logic. If an incorrect operation may cause the equipment status to be unstable (such as load interruption caused by incorrect opening), the system can automatically trigger a rollback mechanism to restore the equipment to a safe state.

[0080] The system adjusts the subsequent task plan based on the verification results, for example: skipping the current operation and giving priority to other unaffected tasks; postponing the affected operation steps until the equipment status meets the conditions. The relevant data of the erroneous operation, including equipment status, verification results, error description and correction suggestions, are automatically recorded in the operation log for subsequent analysis and optimization.

[0081] The unified task management module is used to integrate the operation tasks of all equipment in the entire station, and generate a one-click task list based on the operation steps of multiple devices according to preset logical rules to avoid disconnection of operation links.

[0082] Receive the task objectives entered by the user (such as "main transformer maintenance", "line switching" or "power outage and restoration of the entire station"). Automatically decompose the task objectives into a series of equipment operation tasks (such as circuit breaker opening and closing, isolation switch opening and closing, and grounding switch operation).

[0083] According to the five-defense rules and the preset sequential control logic, the task operation steps are sorted and dependency analyzed. For example: first open the circuit breaker, then operate the isolation switch, and finally operate the grounding switch. Verify the interlocking relationship between devices to ensure that there is no conflict or logic loophole.

[0084] The integrated equipment operation tasks are organized into a one-click task list: each task contains information such as the target equipment, operation type (open / close / start / stop), and execution conditions. The task steps in the list are arranged in the order of execution, and the task priority and dependency are indicated. A visual list interface is provided for operators to support task detail viewing and manual confirmation.

[0085] Set priorities for operation steps according to the importance and urgency of the task: for example, in maintenance tasks, circuit breaker operation takes precedence over isolation switch operation. Urgent tasks (such as accident handling) can be queued up and executed first, and non-urgent tasks can be postponed. Check the equipment status and operating conditions involved in the task to ensure that there is no resource conflict in the same time period: avoid multiple tasks occupying the same equipment or circuit at the same time. Dynamically schedule shared resources to ensure the coordination of the operation sequence. During the task execution process, dynamically adjust the task sequence according to the real-time equipment status and operation results: if a step fails or is delayed, re-evaluate the execution conditions of subsequent tasks. Prioritize other feasible tasks when conditions are met to reduce waiting time.

[0086] Track the progress of task execution in real time and record the status of each step of the operation: if a step is successfully completed, the system automatically triggers the next step. If a step fails, suspend the execution of subsequent tasks and issue an alarm. Perform conditional checks before each task is executed to ensure that the preceding steps have been completed and are logical: for example, isolation switch operations are prohibited when the circuit breaker is not open. If the risk of disconnection is detected (such as skipping important steps), the system immediately interrupts the task execution and prompts the operator. Supports parallel execution of independent equipment tasks to improve task processing efficiency: for example, during the maintenance of the main transformer, the shutdown operations of the line and supporting equipment can be performed simultaneously. Automatically coordinate resource allocation between parallel tasks to avoid mutual interference.

[0087] During task execution, the system detects abnormal situations in real time (such as equipment status mismatch, operation failure, communication interruption, etc.): immediately suspend the affected tasks and record the abnormal information. Prompt the operator to take manual intervention or change the operation plan. If a step fails to execute, it supports automatic triggering of the rollback mechanism to restore the device to a safe state. After the conditions are restored, the system can automatically retry to execute the failed steps, or adjust the task sequence as needed. After the exception handling is completed, a detailed task status report is generated to record the cause of the problem, the handling process and the final result. After the task is completed, the system verifies the status of all involved equipment to ensure that the equipment operation status meets the expected goals. If a state deviation is found, an alarm is generated and the operator is prompted to review. The entire process of task execution is automatically recorded, including operation steps, equipment status changes, exception handling and other information. The log data is stored in the operation record library for subsequent analysis and optimization. Based on the execution record, the operation efficiency and equipment response characteristics are analyzed to provide a basis for optimizing the task scheduling logic and equipment operation strategy.

[0088] In this embodiment, six modules are integrated: sequential control, status confirmation, remote control, video linkage, intelligent error prevention and unified task management. The sequential control module automatically completes the safe switching of circuit breakers, isolation switches and grounding switches based on the preset equipment operation logic and five-protection rules, combined with the real-time status of the equipment; the status confirmation module verifies the status before and after each step of the operation to ensure that the operation results meet expectations, and triggers alarms and corrective measures in case of abnormalities; the remote control module realizes remote control of primary equipment and secondary equipment (such as pressure plates, air switches, etc.); the video linkage module uses real-time monitoring and automatic video archiving to link alarms and assist operators in making quick judgments when the equipment is abnormal; the intelligent error prevention module dynamically verifies the safety of each instruction based on the five-protection rules and logical interlocking, locks the wrong operation and provides correction suggestions; the unified task management module integrates the operation tasks of the entire station equipment, generates a one-click task list, and ensures the consistency and accuracy of the operation process. Through the collaborative work of modules, the system significantly improves the safety, efficiency and intelligence level of electrical equipment operation.
