The implementation of the secondary work safety measure ticket not only ensures personal safety, but also effectively prevents the occurrence of relay protection accidents and ensures the safe and stable operation of the power grid and equipment.

[0003] In the current secondary maintenance of substations, the reliability of secondary circuits mainly depends on the execution and restoration of secondary safety measures tickets.

DETAILED DESCRIPTION

[0023] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for use in the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0024] like Figure 1-5 As shown, the present invention provides a secondary maintenance error prevention system for a substation, the system comprising: a secondary safety measure knowledge base module 10, a safety measure ticket generation module 20, a safety measure task management module 30 and a voice module 40; The secondary security measures knowledge base module 10 is used to store several types of secondary security measures typical tickets and several types of secondary security measures template tickets, and manage the secondary security measures knowledge base; The safety measure ticket generation module 20 is used to call a secondary safety measure ticket suitable for the task from the secondary safety measure typical ticket in the secondary safety measure knowledge base according to the maintenance task requirements, and generate a target secondary safety measure ticket corresponding to the current task; or, based on the secondary safety measure template ticket, generate a target secondary safety measure ticket corresponding to the current task according to the information input by the maintenance personnel; The safety measure task management module 30 is used to inspect and repair the corresponding equipment on site using the target secondary safety measure ticket generated by the safety measure ticket generation module 20; The voice module 40 is used for maintenance personnel to input the content of secondary safety measures using oral voice instructions to generate and edit the target secondary safety measures ticket.

[0025] In this embodiment, it is considered to electronically manage the secondary safety measure tickets through voice recognition technology to improve the work efficiency of on-site inspections before maintenance and realize the electronic, information-based and lean management of maintenance operations.

[0026] In one embodiment, the voice module 40 may include: a voice input unit 41, a voice recognition unit 42 and a voice instruction library 43; A voice command library 43, used to store commonly used secondary Ancuo words and phrases; A voice input unit 41, used to input voice instructions of maintenance personnel during on-site maintenance; The voice recognition unit 42 is used to convert the voice command input by the maintenance personnel through the voice input unit 41 into text information, so as to generate a target secondary safety measure ticket based on the converted text information, or to edit the target secondary safety measure ticket.

[0027] In this embodiment, through voice input technology, maintenance personnel can use oral voice commands to directly enter the content of secondary safety measures, avoid cumbersome manual operations, and improve input efficiency and accuracy. The application of voice input technology can help operators record secondary safety measures information more conveniently in field work and reduce human errors that may be caused by handwritten records. In specific implementation, consider equipping the maintenance site with voice input equipment and voice equipment, and maintenance personnel directly perform voice input through the equipment. Among them, the voice instruction library 43 can be established as a voice instruction library 43 containing commonly used secondary safety measures vocabulary and phrases, so as to facilitate maintenance personnel to quickly input operation content.

[0028] Furthermore, by using voice recognition technology, the system can accurately convert the oral instructions input by maintenance personnel into electronic text, realizing the automatic generation and management of secondary security tickets, which makes the entry of secondary security tickets more convenient and efficient, while reducing errors caused by human operation. Specifically, it is considered to integrate advanced voice recognition engines to recognize the voice instructions input by maintenance personnel in real time, and combine natural language processing algorithms to parse the text content converted from voice, identify key information and generate secondary security tickets in the prescribed format.

[0029] The secondary security knowledge base module 10 may specifically include: a typical security ticket unit 11 and a security ticket template unit 12; The typical safety measure ticket unit 11 is used to establish an index directory for the secondary safety measure tickets of the specific instance according to the first preset classification standard, and completely save the typical safety measure tickets under each classification as secondary safety measure typical tickets in the typical ticket database; wherein the types of the first preset classification standard include: voltage level, interval type and equipment type; The safety measure ticket template unit 12 is used to establish an index directory according to the second preset classification standard, and define the templates of the secondary safety measure tickets corresponding to each classification, and store them as secondary safety measure template tickets in the template ticket database; wherein the types of the second preset classification standard include: plant type, voltage level, wiring method, object type, protection device type, and maintenance work type; the secondary safety measure template ticket includes task name and safety measures, and can support the use of macro variables and macro functions to mark and fill in the task name and safety measure content in the secondary safety measure template ticket.

[0030] In this embodiment, the secondary safety measures knowledge base established may include standard safety measures, common operating procedures and safety requirements, etc., all of which can be obtained by sorting and summarizing the standard specifications and historical data of the power industry. Furthermore, a machine learning algorithm or rule engine can be used in combination with natural language processing technology to model the secondary safety measures knowledge base. The model may include secondary typical safety measures tickets, logical relationships between terms in secondary safety measures tickets, and clauses of safety regulations, etc., so as to facilitate subsequent automatic generation and customization.

[0031] Furthermore, according to the requirements of the knowledge base model, the attributes of the primary and secondary equipment should also be calibrated. The secondary safety measures template ticket constructed by the safety measures ticket template unit 12 should include the task name and safety measures content. For example, if the task name is: 220kV. Line interval. Equipment type. Operation type, the safety measures content is: (1) Check {maintenance object. Protection device. Export hard pressure plate} in the exit state; (2) Put {maintenance object. Protection device. Maintenance pressure plate} into operation.

[0032] Furthermore, the secondary safety measures knowledge base module 10 may also include a knowledge base management unit 13 that implements the management function of the knowledge base, for constructing the content of the knowledge base or optimizing the knowledge base. For example, when constructing the knowledge base, collect and organize the terms and standard processes related to secondary safety measures covering the power maintenance profession. These terms and processes should cover the safety measures requirements for various types of equipment and systems, as well as common operating procedures and safety regulations. The data in the knowledge base can also be classified and archived according to factors such as equipment type, maintenance location, and operating environment, so as to facilitate the rapid positioning and application of appropriate safety measures in actual maintenance operations.

[0033] The knowledge base management unit 13 can also use the safety measures ticket data of past maintenance operations to perform data analysis and mining, identify and extract common safety measures and operating errors, and optimize the content and structure of the knowledge base based on this. Of course, maintenance professionals can also manually correct and supplement the safety measures in the knowledge base based on actual experience and specific circumstances. For example, update new equipment types, adjust safety requirements and operating instructions, etc.

[0034] The knowledge base management unit 13 establishes a database or document to store the knowledge base content, which is convenient for rapid retrieval and update. It also implements a version control mechanism to record each update and modification of the knowledge base, as well as the reasons for the change and the effect evaluation, to ensure the continuous optimization of the knowledge base and the traceability of historical records.

[0035] In addition, the knowledge base management unit 13 can also use machine learning or rule engines to design intelligent matching algorithms to automatically match the most suitable secondary safety measures according to the input maintenance objects and operation scenarios. A feedback mechanism can also be set to optimize the intelligent matching algorithm according to actual operation results and user feedback to ensure that the generated safety measures tickets are more in line with actual needs and standard requirements.

[0036] For the safety measure ticket generation module 20, its goal is to use the secondary safety measure knowledge base module 10 to automatically generate secondary safety measure content that meets the standards according to the maintenance object and the operation scenario. This process supports maintenance personnel to perform manual editing, review and saving operations, and also provides a voice input function to quickly enter safety measure information on site. Specifically, in one embodiment, the safety measure ticket generation module 20 includes: a typical ticket calling unit 21 and a template safety measure ticket generation unit 22; the typical ticket calling unit 21 and the template safety measure ticket generation unit 22 are used to trigger the execution of corresponding functions according to the safety measure ticket generation method selected by the maintenance personnel; The typical ticket calling unit 21 is used to search the typical ticket for the secondary safety measure suitable for the current task from the typical ticket database according to the maintenance task requirements, and call the secondary safety measure typical ticket to generate a target secondary safety measure ticket corresponding to the current task; The template safety measure ticket generating unit 22 is used to generate a target secondary safety measure ticket according to the maintenance object and maintenance work type input by the maintenance personnel and the template ticket database, combined with the primary and secondary equipment ledger data of the substation.

[0037] In this embodiment, the system identifies and extracts the corresponding safety measures requirements based on the maintenance object and operation scenario selected by the maintenance personnel. For example, after the relay maintenance operator receives the maintenance task, when creating a secondary safety measures ticket on the system according to the task requirements, the secondary safety measures ticket can be generated in the following two ways: (1) According to the maintenance task requirements, find the secondary safety measures ticket suitable for this task in the "Typical Ticket Database" through query, filtering, etc., then call and generate a new secondary safety measures ticket.

[0038] (2) Through the new task function, input the maintenance object and maintenance work type. The system automatically generates a secondary safety measure ticket based on the template ticket database of the secondary safety measure knowledge base module 10 and the primary and secondary equipment ledger data of the substation.

[0039] Furthermore, when the template safety measure ticket generation unit 22 generates a secondary safety measure ticket by adopting a new function, it is used to obtain the maintenance object attributes of the maintenance object according to the maintenance object, maintenance type and primary and secondary equipment inventory data input by the maintenance personnel; and, according to the maintenance object attributes, match the corresponding secondary safety measure template ticket from the template ticket database, and calculate and fill in the macro functions and macro variables of the matched secondary safety measure template ticket type to generate a target secondary safety measure ticket; wherein, the maintenance object attributes include: voltage level, interval type and equipment type.

[0040] The system provided by this solution supports maintenance personnel to edit and set the generated safety measures tickets, such as adding specific operation steps, adjusting safety requirements and supplementing detailed information, etc. This process can be carried out through voice input or through a graphical user interface.

[0041] After the generation and customization are completed, the secondary safety ticket needs to be manually reviewed to ensure the compliance of the content and the rigor of the logic. After the review is passed, the system will save the secondary safety ticket to the electronic database and automatically archive it. This data can not only be used for current maintenance work, but also as a reference and reuse for future work.

[0042] It can be seen that in this embodiment, the security ticket generation module 20 greatly simplifies the process of formulating secondary security tickets through intelligent generation and voice input technology, reduces the possibility of human errors and input time, and improves the execution efficiency and safety of maintenance operations; and the system supports customization of secondary security tickets according to specific needs, so as to better adapt to different maintenance tasks and on-site conditions.

[0043] In one embodiment, the system further includes an image acquisition module 50, such as a camera, for capturing images of the on-site maintenance equipment during maintenance.

[0044] The safety task management module 30 is used to perform intelligent inspection on the image data before, during and after the maintenance of the secondary safety task through intelligent inspection technology. This technology ensures that the wiring terminals and ports during and after the maintenance meet the requirements of the secondary safety ticket by matching the detection line points. Throughout the process, the system distribution provides maintenance personnel with dangerous point notifications, warns of the consequences that may result from safety errors, ensures the correct implementation of each safety measure, and avoids the occurrence of relay protection misoperation and refusal to operate due to human factors.

[0045] Specifically, the security task management module 30 may include a security ticket calling unit 31, an image acquisition calling unit 32, an image marking unit 33 and an analysis unit 34; The safety measure ticket calling unit 31 is used to call the target secondary safety measure ticket generated by the safety measure ticket generating module 20 before the maintenance; The image acquisition calling unit 32 is used to call the image acquisition module 50 to take images of the terminals that need to be released in the target secondary safety measure ticket before the inspection, after the safety measure task is executed, and after the inspection is completed; wherein the three image shots refer to the same reference point; An image marking unit 33 is used to mark the terminals that need to be released in the photos taken by the image acquisition and calling unit 32 before the maintenance, so as to obtain a marked image before the maintenance; The analysis unit 34 is used to compare the maintenance release diagram taken after the execution of the security task with the marking diagram before maintenance, to determine whether the terminals released after the execution of the security task are the marked terminals; and to compare the post-maintenance restoration diagram taken after the maintenance is completed with the marking diagram before maintenance, to determine whether the marked terminals are restored after the maintenance task is completed.

[0046] Furthermore, the analysis unit 34 is used to identify the terminals marked in the pre-maintenance marking diagram, the maintenance release diagram and the post-maintenance restoration diagram based on the residual network image recognition technology, and to compare the terminal states identified in the maintenance release diagram and the post-maintenance restoration diagram with the terminal states identified in the pre-maintenance marking diagram for consistency.

[0047] In this embodiment, AI algorithms are used to assist in intelligent inspection, with special attention paid to the correctness of the terminals and ports, to ensure that the safety measures implemented in the security ticket are correctly implemented. The image acquisition module 50 can use a high-resolution camera or a smart phone to collect image data, and can further perform denoising, enhanced contrast, and edge detection on the image.

[0048] During intelligent inspection, consider using the ResNet residual convolutional neural network architecture for target detection and segmentation, apply deep learning models such as YOLO or Faster R-CNN to identify wires and connection points, and use SIFT or SURF algorithms for feature point matching. Specifically, perform intelligent inspections on image data before, during, and after maintenance, combine voice recognition and intelligent voice reminders to match the detection line points, and determine whether the wiring terminals and ports during and after maintenance are consistent with the requirements of the secondary safety measures ticket. During the entire process and in steps, maintenance personnel are informed of dangerous points and the possible consequences of safety measures errors, and double-checked based on voice feedback and image recognition technology to ensure that each step of safety measures is implemented correctly and in place.

[0049] In addition, the system may also include a historical ticket library management module 60; The historical ticket library management module 60 is used to store the target secondary safety measure ticket and key data of each maintenance task into the historical ticket library after the maintenance task is completed; wherein the key data includes: task information, execution time and operator.

[0050] In this embodiment, after the secondary security measure task is completed, the secondary security measure ticket management module automatically archives the secondary security measure ticket and stores it in the historical ticket library as a historical ticket. This process can trigger automated operations based on the status or time of the task to ensure that all completed tasks are archived in a timely manner. When archiving and storing the secondary security measure ticket, it also includes storing key data such as detailed task information, execution time, and operator. Each archived security measure ticket should contain complete task content and operation records for future reference and analysis.

[0051] The historical ticket database management module 60 can also have data collection and analysis functions, and can extract key indicators and performance data from archived secondary security measures tickets, such as task execution efficiency, safety measures compliance, etc. Further, performance reports and statistical analysis results are automatically generated to help managers evaluate the quality and efficiency of security measures execution. Reports can be classified based on time period, equipment type or operation type to provide strong support for decision-making.
