Description

Technical Field

[0001] This invention relates to a dynamic indication method and system for safety measures marking multiple work sites in substations, belonging to the field of power technology. Background Technology

[0002] Traditionally, safety measures in substations are implemented primarily through manual review and verification of the safety measures outlined in the work order before actual deployment. This method is not only prone to errors in safety measure deployment, but the probability of error is even higher in scenarios involving multiple work areas operating simultaneously.

[0003] Chinese invention patent application CN116778106A discloses a method and device for digital 3D modeling and safety measure layout in substations. This solution enables the layout of safety measures within a substation. According to this solution, firstly, a laser scanner is used to collect data, process and model the point cloud data to form a 3D model, and the management platform intelligently visualizes the safety measure layout diagram. Next, based on the equipment location coordinates, layout diagram rules are set, and the work order safety measure layout content is scanned to match the name and location coordinates (the specific scanning method for work order safety measure layout content is not given in the text), generating the layout diagram according to the rules. Finally, a fence is generated in the 3D map, and fence entrances and exits and safety signs are set.

[0004] The aforementioned solution proposes a digital 3D modeling method and device for substation safety measure layout, capable of generating a fence layout diagram. However, 3D modeling technology is time-consuming, costly, and difficult to maintain in the later stages. Furthermore, the solution does not provide a method for recognizing work order text. In addition, for situations where multiple work areas overlap on-site, the solution does not propose an effective method to avoid fence layout errors that may result from overlapping safety measures, thus exhibiting certain limitations. Summary of the Invention

[0005] To address the problems existing in the prior art, this invention proposes a dynamic indication method and system for safety measures signage on multiple work sites in substations.

[0006] The technical solution of the present invention is as follows: On the one hand, the present invention provides a method for dynamic indication of safety measures on multiple work fronts in substations, comprising the following steps: Based on the existing panel layout plan and equipment ledger information, a multi-dimensional ledger database for substations is constructed. The multi-dimensional ledger database for substations includes multiple storage spaces, each storage space corresponds to a panel in the substation, and each storage space stores the location information and ledger information of the panel. Semantic analysis is performed on the safety measures information in the work order to extract the counter account information and the corresponding safety measures tasks, wherein the safety measures tasks include at least one safety measure item. Based on the information in the substation's multidimensional ledger database, the corresponding storage space for the substation's cabinet is queried, and the corresponding safety measures tasks are stored in the storage space. Based on the safety measures tasks in all storage spaces, a safety measures layout diagram is generated and distributed to the operators, who then implement the safety measures according to the diagram.

[0007] Preferably, the safety measures task includes multiple safety measures items and a bill of materials.

[0008] Preferably, the safety measure layout diagram includes the location information of each cabinet, the placement location markings of the safety measures for each cabinet, and the material information required for the safety measure layout of each cabinet.

[0009] Preferably, when a new work order is received, a new safety measure task is generated and stored in the corresponding storage space. In each storage space, the safety measure item status and material list of the safety measure task in the current storage space are updated according to the safety measure items and material list in the new safety measure task. Once all storage space has been updated, the safety layout diagram will be regenerated.

[0010] Preferably, the correctness of the safety measures information on the work order is verified, specifically as follows: Extract all cabinet names from the safety measures information and compare them with the cabinet account information in each storage space of the substation multidimensional ledger database. If a cabinet name fails the consistency comparison, issue an early warning that the work order contains an incorrect cabinet name.

[0011] Preferably, a work order archiving database is constructed, which includes a sub-database of work orders that have commenced and a sub-database of work orders that have not yet commenced. Once the work order passes the correctness verification, its unique identifier and corresponding safety measures information are stored in the unstarted work order sub-database. When the safety measures information of the work order has been recorded in the substation's multidimensional ledger database, the unique identifier of the work order and the corresponding safety measures information in the unstarted work order sub-database will be transmitted to the started work order sub-database.

[0012] Preferably, the work order archiving database also includes a terminated work order sub-database. When a work order is terminated, the unique identifier of the work order and the corresponding safety measures information in the started work order sub-database are transmitted to the terminated work order sub-database. For each work ticket in the completed work ticket sub-database, update its safety measures task in the substation multidimensional ledger database, and regenerate the safety measures layout diagram based on the updated substation multidimensional ledger database.

[0013] On the other hand, the present invention also provides a dynamic indication system for safety measures on multiple work surfaces in substations, including a substation multi-dimensional ledger database construction module, a safety measure task extraction module, a safety measure task storage module, and a safety measure task distribution module; The substation multidimensional ledger database construction module is used to construct a substation multidimensional ledger database. The substation multidimensional database includes multiple storage spaces, each storage space corresponds to a cabinet in the substation, and each storage space stores the location information and ledger information of the cabinet. The safety measure task extraction module is used to perform semantic analysis on the safety measure information in the work order, extract the counter account information and the corresponding safety measure task, and the safety measure task includes at least one safety measure item. The safety measure task storage module is used to query the storage space corresponding to the panel in the substation multidimensional ledger database according to the panel ledger information, and store the corresponding safety measure task in the storage space. The safety measure task distribution module is used to generate a safety measure layout diagram based on the safety measure tasks in all storage spaces and distribute it to the operators.

[0014] In another aspect, the present invention also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the method described in the present invention.

[0015] In another aspect, the present invention also provides a computer-readable storage medium having a computer program stored thereon that, when executed by a processor, implements the method described in the present invention.

[0016] The present invention has the following beneficial effects: 1. The substation multi-dimensional ledger database proposed in this invention is built based on existing ledgers and drawings, eliminating the need to rebuild the system and significantly reducing implementation difficulty and cost. Semantic analysis and dynamic decision-making methods are applied to work order safety information to form a full-process closed-loop safety management system and method based on a real-time safety status database. This system features equipment name accuracy verification, supports safety compatibility verification for cross-operation areas, and provides intuitive, visual safety deployment instructions to guide operators in accurately implementing or retrieving safety measures.

[0025] The term “and / or” refers to any combination of one or more of the associated listed items, as well as all possible combinations, and includes these combinations.

[0026] See Figure 1 In some embodiments, a dynamic indication method for safety measures labeling at multiple work sites in substations is proposed, including the following steps: A multi-dimensional ledger database for substations is constructed. The multi-dimensional ledger database for substations includes multiple storage spaces. Each storage space corresponds to a cabinet in the substation, and each storage space stores the location information and ledger information of the cabinet. Semantic analysis is performed on the safety measures information in the work order to extract the counter account information and the corresponding safety measures tasks, wherein the safety measures tasks include at least one safety measure item. Based on the information in the substation's multidimensional ledger database, the corresponding storage space for the substation's cabinet is queried, and the corresponding safety measures tasks are stored in the storage space. Based on the safety measures tasks in all storage spaces, a safety measures layout diagram is generated and distributed to the operators, who then implement the safety measures according to the diagram.

[0027] See Figure 2In one specific embodiment, 10 cabinets in a certain substation are listed, and the substation multidimensional ledger database opens 10 storage spaces for them. Based on the floor plan of the display cabinets, query the location information of the display cabinets and enter it into the corresponding storage space. At the same time, based on the existing display cabinet account data, store the name of each display cabinet in the corresponding storage space.

[0028] In some embodiments, the safety measures task includes multiple safety measures items and a bill of materials.

[0029] In some embodiments, the safety measure layout diagram includes the location information of each cabinet, the placement location identifier of the safety measures for each cabinet, and the material information required for the safety measure layout of each cabinet.

[0030] In one specific embodiment, the location information of the cabinet is the relative position of the cabinet within a preset range.

[0031] In one specific embodiment, semantic analysis of safety measures information in the work order is performed using a large language model; For example: Determine the meaning of "hanging "Working Here" signs in front and behind the 3J Line 2 Protection A and 4J Line 2 Protection B screens respectively, hanging "In Operation" signs in front and behind adjacent operating cabinets, and installing "Equipment in Operation" safety fences around the perimeter; The following security measures were obtained from the large language model analysis: A sign reading "Working Here" is hung in front of the 2nd protection panel cabinet of line 3J; A sign reading "Working Here" is hung behind the 2nd protection panel cabinet of line 3J; A sign reading "Working Here" is hung in front of the 4J line 2 protection panel B cabinet; A sign reading "Working Here" is hung behind the B protection panel of line 4J. A sign indicating "In Operation" is hung in front of the B-side protection cabinet of line 2J. A sign indicating "In Operation" is hung behind the B-side panel of the 2J line protection system. Place a "Equipment in Operation" safety barrier in front of the B protection panel cabinet of line 2J; Place a "Equipment in Operation" safety fence behind the B panel of the 2J line 1 protection unit; A sign indicating "In Operation" is hung in front of the 5J DC splitter cabinet; A sign indicating "In Operation" is hung behind the 5J DC splitter cabinet; Place a "Equipment in Operation" safety barrier in front of the 5J DC splitter cabinet; Place a "Equipment in Operation" safety fence behind the 5J DC splitter cabinet; The large language model, combined with safety measures and the location information of the cabinet, outputs as follows: Figure 3The safety measures layout diagram is shown.

[0032] In some embodiments, when a new work order is received, a new safety measure task is generated and stored in the corresponding storage space. In each storage space, the safety measure item status and bill of materials of the safety measure task in the current storage space are updated according to the safety measure items and bill of materials in the new safety measure task. Once all storage space has been updated, the safety layout diagram will be regenerated.

[0033] In one specific embodiment, Figure 3 Based on existing safety measures, when a new work order is received, its safety measures information is as follows: Hang "Working Here" signs before and after the "Protection A Panel of Line 9J"; hang "In Operation" signs before and after adjacent operating panels; and install a "Equipment in Operation" safety fence around the perimeter. After semantic analysis by the large language model, the following safety measures are obtained: Remove the "In Operation" sign hanging in front of the 9J line 2 protection A panel cabinet; Remove the "In Operation" sign hanging behind the 2nd protection panel cabinet of line 9J; A sign reading "Working Here" is hung in front of the 9J line 2 protection A panel cabinet; A sign reading "Working Here" is hung behind the 9J line 2 protection A panel cabinet; A sign indicating "In Operation" is hung in front of the 4th protection panel B of line 10J; A sign indicating "In Operation" is hung behind the B-type protection cabinet of line 10J. Place a "Equipment in Operation" safety barrier in front of the 4th protection panel cabinet of line 10J; Place a "Equipment in Operation" safety fence behind the 4th protection panel of line 10J; A sign indicating "In Operation" is hung in front of the B-side panel of the 8J line 3 protection unit; A sign indicating "In Operation" is hung behind the B-type protection cabinet of line 3 in the 8J line. Place a "Equipment in Operation" safety barrier in front of the 8J line 3 protection B panel cabinet; Place a "Equipment in Operation" safety fence behind the 8J line 3 protection B cabinet; The large language model combines new safety measures, compares them with existing safety measures, and considers the location information of the screen cabinet to output, as follows: Figure 4 The safety measures layout diagram is shown.

[0034] In some embodiments, the correctness of the safety measures information on the work order is verified, specifically as follows: Extract all cabinet names from the safety measures information and compare them with the cabinet account information in each storage space of the substation multidimensional ledger database. If a cabinet name fails the consistency comparison, issue an early warning that the work order contains an incorrect cabinet name.

[0035] In one specific embodiment, pre-approved work order information is read from the PMS3.0 platform, and the correctness of all cabinet names within it is verified. The verification specifically covers cabinet names mentioned in the "Work Task" description and key items such as "Required barriers, required signage, and measures to prevent accidental contact with secondary circuits." If any cabinet name in the above items is inconsistent with the naming in the system's ledger database, a prompt message is automatically generated to remind relevant personnel to correct it promptly, ensuring the accuracy and consistency of cabinet naming.

[0036] In some embodiments, a work order archive database is constructed, which includes a work order sub-database of started work and a work order database of not started work; Once the work order passes the correctness verification, its unique identifier and corresponding safety measures information are stored in the unstarted work order sub-database. When the safety measures information of the work order has been recorded in the substation's multidimensional ledger database, the unique identifier of the work order and the corresponding safety measures information in the unstarted work order sub-database will be transmitted to the started work order sub-database.

[0037] In some embodiments, the work order archiving database also includes a terminated work order sub-database. When a work order is terminated, the unique identifier of the work order and the corresponding safety measures information in the started work order sub-database are transmitted to the terminated work order sub-database. For each work ticket in the completed work ticket sub-database, update its safety measures task in the substation multidimensional ledger database, and regenerate the safety measures layout diagram based on the updated substation multidimensional ledger database.

[0038] In some embodiments, a dynamic indication system for safety measures listing on multiple work surfaces in a substation is proposed, including a substation multi-dimensional ledger database construction module, a safety measure task extraction module, a safety measure task storage module, and a safety measure task distribution module. The substation multidimensional ledger database construction module is used to construct a substation multidimensional ledger database. The substation multidimensional database includes multiple storage spaces, each storage space corresponds to a cabinet in the substation, and each storage space stores the location information and ledger information of the cabinet. The safety measure task extraction module is used to perform semantic analysis on the safety measure information in the work order, extract the counter account information and the corresponding safety measure task, and the safety measure task includes at least one safety measure item. The safety measure task storage module is used to query the storage space corresponding to the panel in the substation multidimensional ledger database according to the panel ledger information, and store the corresponding safety measure task in the storage space. The safety measure task distribution module is used to generate a safety measure layout diagram based on the safety measure tasks in all storage spaces and distribute it to the operators.
