Description

Technical Field

[0001] This invention belongs to the field of substation switching operation safety technology, and in particular to a smart operation method based on fully online error prevention. Background Technology

[0002] Substation operation and maintenance (O&M) personnel are responsible for the operation and maintenance of substations, switching operations, accident handling, and equipment inspections, playing a crucial role in the power system. Switching operations, as the most basic, frequent, and core task in O&M, have always placed paramount importance on safety.

[0003] Operational monitoring refers to a work method in which a monitor supervises and controls the behavior and status of the operator during switching operations to prevent threats to personal safety, equipment, and the safe and stable operation of the power grid. It is a crucial measure to ensure production safety. The "Electric Power Safety Work Regulations" stipulate that a dedicated monitor must be present during switching operations to ensure personal safety. Therefore, effective operational monitoring is a vital guarantee for safe production. However, in practice, the existing model presents new challenges:

[0004] 1) Issues of work efficiency and effectiveness. As the power grid becomes increasingly intelligent, the number of operators is decreasing, and the current two-person operation mode cannot meet the future trend of single-person operation. The contradiction between the continuous growth of production equipment and the gradual reduction of personnel is becoming increasingly prominent, making the company's need for staff reduction and efficiency improvement urgent.

[0005] 2) The process of the supervisor announcing the votes and the operator repeating them is greatly affected by the external environment, weather, and lighting. Whether they are consistent depends entirely on the supervisor's sense of responsibility. When there are complex and large-scale operations, the lack of physical strength and energy of the operators and supervisors may lead to a decrease in the rigor of the supervision work, and there is a risk of misalignment, errors in announcing the votes, or errors in repeating them.

[0006] 3) Risk of going to the wrong interval during execution, or mistakenly activating or deactivating secondary pressure plates or circuit breakers. Interval verification and equipment status checks are all done manually under poor external conditions, which greatly increases the risk of going to the wrong interval or misreading the equipment status.

[0007] 4) Lack of pre-operation risk control. While there is potential hazard analysis for this operation, and methods for controlling the risks involved are not readily available, the execution process still relies primarily on personnel experience. There is a lack of dynamic risk assessment based on actual operation and equipment conditions, and a failure to implement process-oriented management during the operation.

[0008] To better address the above issues, it is an inevitable requirement for development to improve production efficiency and effectiveness, reduce safety risks, enhance the power grid's production and operation level and equipment health level by applying intelligent technologies, and ultimately achieve intelligent operation of the power grid. Summary of the Invention

[0009] The purpose of this invention is to provide a smart operation method based on fully online error prevention, which can reduce the number of operators, realize full online control of the operation process, and reduce safety risks.

[0010] This invention provides a smart operation method based on fully online error prevention, and its technical solution to the technical problem includes the following steps:

[0011] 1. Receive and correctly identify the operation content and requirements of the switching operation ticket;

[0012] 2. Verify that the operators have arrived at the designated operating positions;

[0013] 3. The smart guardian announces the current operation steps of the vote by voice and listens to and verifies whether the operator repeats the operation content correctly;

[0014] IV. Once the smart guardian reads out the votes and the operator repeats and verifies them, the operation permission for the current operation will be activated to the "operable" state (only the current operation process will be activated to the "operable" state each time).

[0015] 5. The operator uses the computer key to unlock and read the code, and feeds back the read device information to the smart guardian to determine whether the current step is the step for which the current operation right is activated. If so, the operator can unlock; otherwise, unlocking is prohibited.

[0016] 6. The smart guardian receives the unlocking result from the computer key unlocker and verifies whether the operation result of the current operation step has been completed as required. If the operation requirements of this step are met, this step is completed.

[0017] 7. Repeat steps one through six above until all operations are performed correctly, then end the switching operation.

[0018] Preferably, in step one, the paper operation ticket is photographed and recognized by a mobile APP program or a switching operation ticket is generated by the five-prevention system.

[0019] Preferably, during the generation of switching operation tickets, the system will also combine the hazard point database and analyze the data from the hazard point expert database to form a list of hazard point analysis and pre-control measures.

[0020] Preferably, in step two, by receiving real-time location information of personnel, it is intelligently determined whether the operator has reached the designated area; if the operator goes to the wrong interval, an alarm will be issued immediately, and the operation and maintenance center will be notified for remote monitoring.

[0021] Preferably, the verification method in step six includes: using remote signaling equipment to determine whether the operation is completed based on the real remote signal received from the monitoring backend.

[0022] Preferably, the verification method in step six includes: for the pressure plate device, using photo recognition of the pressure plate device status as the basis for determining whether the operation is completed.

[0023] Preferably, the verification method in step six includes the grounding wire and grounding knife device for the gate: the unlocking operation of the unlocker is used as the basis for determining the completion of the operation.

[0024] Preferably, in conjunction with the hazard point pre-control list, pre-control reminders are given in real time step by step during the execution of the switching operation ticket. If any abnormality occurs, an alarm is triggered and corresponding mandatory control (operation restriction) is implemented.

[0025] Preferably, the entire process of executing the switching operation ticket is remotely monitored online by the fully online anti-misoperation switching operation and maintenance center.

[0026] In summary, the application of the technical solution of the present invention has at least the following beneficial effects:

[0027] 1. It enables intelligent guardians to replace traditional natural person guardians, reducing the number of human interventions required;

[0028] 2. Operational risks can be dynamically assessed based on actual operation and equipment conditions, and process-oriented control can be implemented during operation.

[0029] 3. It can improve the power grid's production and operation level and equipment health level. Attached Figure Description

Obviously, the accompanying drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0033] Figure 3 This is a schematic diagram of the switching operation ticket operation process of the present invention. Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] This invention provides a smart operation method based on fully online error prevention. During the specific operation, the entire process is remotely monitored online by a fully online error prevention switching operating system (operation and maintenance center). During operation, a smart monitor (not a natural person, which can be understood as an online monitoring system) is present; such as... Figure 1-3 As shown, it includes the following steps:

[0036] 1. Receive and correctly identify the operation content and requirements of the switching operation ticket; in this step, an electronic switching operation ticket is generated for use by the system in the operation process. The specific identification methods are as follows:

[0037] Method 1: Perform a simulated operation on the five-prevention system and generate a five-prevention switching operation ticket according to the switching operation requirements;

[0038] Method 2: According to the switching operation requirements, select the operation object, initial state, and target state on the five-prevention system to automatically generate a ticket;

[0039] Method 3: The operator photographs the paper ticket, identifies the task name and operation content, and intelligently generates a ticket based on the identified task name, parsing out the operation object, initial state, and target state. In this method, a scanner can be used to identify the content of the paper operation ticket. During this step, intelligent ticket generation only requires selecting or inputting the corresponding operation object, initial state, and target state to automatically generate the corresponding operation ticket. This significantly improves the efficiency and quality of operation ticket generation, reducing the workload and requirements for ticket generation for operators. Furthermore, during the generation of switching operation tickets, the system also integrates a hazard database and analyzes data from a hazard expert database to form a list of hazard analysis and pre-control measures.

[0040] 2. Verify that the operator has reached the designated operating position; the mobile APP is linked with the fully online error prevention system to intelligently verify and analyze whether the pre-operation preparations are in place by judging the management status of safety tools; by receiving real-time personnel location information, it intelligently determines whether the operator has reached the designated area. If it is found that the corresponding tools and operators have reached the preset designated operating position, the voice announcement begins (step 3). If the wrong interval is entered, an alarm is immediately triggered, and the operation and maintenance center is notified for remote monitoring (focusing on monitoring based on alarm prompts); during specific operations, high-precision positioning technologies such as WIFI, Bluetooth, RFID, and UWB can be used in conjunction with the switching operation ticket content to prevent operators from entering the wrong interval. According to the operation and maintenance task, the system automatically determines the personnel access permissions of each operator based on the positioning location. Once an incorrect interval is entered, the system automatically alarms, ensuring immediate alarm reminders for abnormalities. At the same time, the historical movement trajectory of the operators is stored and recorded to provide support for big data analysis of the operator's behavior.

[0041] Third, the intelligent monitoring system uses voice to announce the current operation steps and listens to verify the operator's recitation of the operation content. The intelligent monitoring system is equipped with a voice intelligent recognition module and a voice broadcasting module. It listens to and recognizes the content repeated by the operator and compares it with the content to be performed. If the comparison is consistent, it indicates that the operator knows and understands the content to be performed. This human-machine voice-announcement and recitation verification based on voice recognition technology checks the consistency between the content and the operation ticket task, standardizes the voice-announcement and recitation procedures during the operation process, and improves the safety of switching operations.

[0042] The intelligent voice recognition module is combined with digital operation tickets.

[0043] Voice-based ticket reading requires an electronic operation ticket, enabling automatic voice reading of each operation step. After the operator repeats the steps, the system recognizes the repeated content and uses keyword matching to verify the correctness of the actions and device numbers in the repeated results. It also allows for command-based wake-up and exit from the voice recognition system. Furthermore, it can intelligently match commonly used terminology on operation tickets and supports Cantonese recognition.

[0044] IV. Once the smart guardian reads out the votes and the operator repeats and verifies them, the operation permission for the current operation will be activated to the "operable" state (only the current operation process will be activated to the "operable" state each time).

[0045] 5. The operator uses the computer key to unlock and read the code, and feeds back the read device information to the smart guardian to determine whether the current step is the step for which the current operation right is activated. If so, the operator can unlock; otherwise, unlocking is prohibited.

[0046] 6. The smart guardian receives the unlocking result from the computer key unlocker and verifies whether the operation result of the current operation step has been completed as required. If the operation requirements of this step are met, this step is completed.

[0047] It should be noted that, in actual operation, in order to further improve the quality of management and control, the operator (natural person) must undergo facial recognition and electronic signature before executing the operation ticket.

[0048] The verification in step six includes the following three methods: 1. Using remote signaling equipment: using the received remote signal from the monitoring backend as the basis for judging whether the operation is completed. 2. Using a pressure plate device: using the image recognition of the pressure plate device status as the basis for judging whether the operation is completed. Through the implementation of the on-site image recognition of the pressure plate status module, the recognition result is combined with the operation ticket to determine whether the current pressure plate operation is completed correctly. 3. Using other devices such as the grounding wire of the mesh door: using the unlocking operation of the unlocker as the basis for judging whether the operation is completed.

[0049] Specifically, taking the status of the pressure plate equipment as an example: 1) After the operation ticket is verified by the integrated intelligent error prevention system, the operation task is sent to the intelligent terminal;

[0050] 2) Based on the assigned task, perform operations on the corresponding area and equipment. The smart terminal obtains the corresponding lock authorization based on the task, including room door locks, cabinet locks, etc.

[0051] 3) When the task matches the lock, the smart terminal is allowed to open the corresponding lock via the unlocker; otherwise, a failure message is returned.

[0052] 4) After the cabinet door is opened, the smart terminal prompts the hard plate operation according to the acquired operation task. After the operation is completed, it prompts the user to take a picture. After the picture is taken, the system verifies the correctness of the operation in real time and provides real-time feedback on status information and alarm information.

[0053] 5) If the operation is deemed abnormal or all operation steps are completed, the task execution will be terminated.

[0054] It should be noted that room door locks and cabinet locks also support remote online unlocking.

[0055] 7. Repeat steps one through six above until all operations are performed correctly, then end the switching operation.

[0056] The entire process of switching operation is combined with the hazard pre-control list. During the execution process, pre-control reminders are given in real time step by step. At the same time, if there is any abnormality, an alarm is triggered and corresponding mandatory control (operation restriction) is implemented.

[0057] The entire process of executing the switching operation ticket is remotely monitored online by the fully online anti-misoperation switching operation and maintenance center. The station promptly reports real-time video information, location information, and operation ticket status information of the operation process to the fully online anti-misoperation switching operation and maintenance center. When the operation and maintenance center needs to suspend or terminate the on-site operation, it can issue a pause or termination command to suspend or terminate the on-site operation, so that the on-site switching operation process can be viewed and controlled from the center.

[0058] Please note the attached document. Figure 3 In practical applications, the intelligent guardian management system can be integrated with the substation's five-prevention system into one system or managed separately.

[0059] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
