Description

Technical Field

[0001] The present application relates to the technical field of power operation sign management, and in particular to an intelligent management system and method for power operation signboards. Background Art

[0002] Before conducting equipment maintenance and overhaul in production areas, power companies must implement safety measures such as power outages and isolation to ensure personal and equipment safety. These measures primarily include disconnecting switches, closing valves, and installing grounding wires. After each safety measure is implemented, warning signs must be hung on the corresponding switches and valves to prevent personnel from inadvertently actuating safety measures, potentially leading to energized or pressurized equipment, or accidental activation, resulting in serious injury, death, and equipment damage. Therefore, the display and management of power operation signage is a management measure to ensure personal and equipment safety.

[0003] Current power companies primarily rely on manual management for power operation signage: Plant-wide equipment is given dual names and numbers (e.g., 500kV XX Power Plant First String Interconnector XXXX Switch, Unit X Volute Intake Valve XXXX), and hanging signage is numerically numbered by type (e.g., "Do Not Close 001" signage, "Do Not Operate 009" signage) to ensure the uniqueness of operating equipment and signage. When equipment maintenance and safety measures are implemented, signage is hung on the corresponding equipment, and the equipment name and number, as well as the signage name and number, are handwritten on the maintenance work ticket. Existing technologies suffer from low recognition efficiency, high error rates, low manual transcription efficiency, and an inability to intelligently track signage and prevent accidental locking. These issues hinder the safety of power operation sites. Therefore, a power operation signage management solution that can ensure the safety of power operation sites is urgently needed.

[0051] The following describes an intelligent management system for electric power operation signage according to an embodiment of the present application with reference to the accompanying drawings.

[0052] Example 1

[0053] Figure 1 This is a structural diagram of an intelligent management system for electric power operation identification signs provided according to one embodiment of the present application, such as Figure 1 As shown, the system includes: multiple power equipment RFID digital tags 1, multiple power operation identification plate RFID digital tags 2, a handheld mobile terminal device 3, and a power equipment basic database 4, wherein the power equipment RFID digital tags 1 and the power operation identification plate RFID digital tags 2 are both composed of RFID chips;

[0054] The plurality of electric equipment RFID digital tags 1 are respectively set on each electric equipment in the production area of ​​the electric power enterprise, and the plurality of electric operation identification plate RFID digital tags 2 are respectively set on each electric equipment in operation in the production area of ​​the electric power enterprise;

[0055] The electric power equipment RFID digital tag 1 is used to store digital coding information of electric power equipment in the production area of ​​the electric power enterprise;

[0056] The RFID digital tag 2 of the electric power operation identification plate is used to store the digital coding information of the electric power operation identification plate;

[0057] The handheld mobile terminal device 3 is used to identify the RFID digital tags 1 of each power device, obtain the name information of each power device, and send the name information of each power device to the power device basic database 4;

[0058] The handheld mobile terminal device 3 is also used to identify each of the electric power operation identification signs RFID digital tags 2, obtain the operation information of each electric power equipment in operation, and send the operation information of each electric power equipment in operation to the electric power equipment basic database 4;

[0059] The handheld mobile terminal device 3 is provided with a handheld mobile terminal management APP 3-1, which is used to create a work task and generate an electric power work identification plate RFID digital tag 2 corresponding to the work task;

[0060] The handheld mobile device 3 is also used to scan the RFID digital tag 2 of the power operation identification sign corresponding to the operation task when the staff completes the operation, obtain the equipment name information, sign type, and sign number corresponding to the operation task, and update the power equipment basic database 4.

[0061] It should be noted that Figure 1The structural diagram of the intelligent management system for electric power operation signage shown is only for illustration and does not limit the structure of the intelligent management system for electric power operation signage of the present invention.

[0062] In the embodiment of the present disclosure, the handheld mobile device 3 is an NFC-enabled phone or an RFID code scanning device.

[0063] In the embodiment of the present disclosure, Figure 2 As shown, the system further includes: a WEB server 5;

[0064] The WEB server 5 is used to store the equipment name information, nameplate type, and nameplate number corresponding to the operation task.

[0065] It should be noted that all equipment (switches, valves, etc.) that need to be operated in the production area of ​​the power enterprise are given dual names and numbers (for example: the first string of connecting XXXX switches of 500kV XX power plant, the volute water intake valve XXXX of unit X) to ensure that the operating equipment is named uniquely, and RFID electronic tags are affixed to the equipment operation panel or handle. The electronic tag information is identified using a handheld mobile device 3 (NFC-enabled mobile phone, RFID scanning device) and entered into the power equipment basic database 4 to ensure that the power equipment name corresponds to the RFID digital tag, thereby realizing digital coding of the equipment.

[0066] Digitally encode all power operation signage within the power company's production area. Classify and number existing power operation signage within the power company's production area (for example, "No Closing 001" signage, "No Operation 009" signage), ensure unique naming of power operation signage, attach RFID electronic tags to power operation signage, use handheld mobile devices (NFC-enabled phones, RFID scanners) to identify the electronic tag information, and enter it into the power operation signage basic database to ensure that the power operation signage name corresponds to the RFID digital tag, thereby achieving digital encoding of the signage.

[0067] Before carrying out maintenance and inspection on the equipment in the production area of ​​the power enterprise, open the handheld mobile terminal management APP 3-1 on the handheld mobile terminal device 3 to create an operation task such as Figure 3 As shown, this operation task is used to identify and automatically record the implementation of maintenance and inspection safety measures and the installation of identification plates.

[0068] After the handheld mobile terminal management APP3-1 completes the creation of the operation task, the operation and maintenance personnel perform the isolation safety measures according to the operation ticket and need to operate the equipment (for example, switches, valves). After completing the single safety measure operation, the handheld mobile terminal device 3 is used to automatically identify the electronic tag information. The handheld mobile terminal management APP3-1 calls the background power equipment basic database 4 according to the electronic tag information to identify the corresponding equipment information and automatically enters it into the equipment information column of the handheld mobile terminal management APP3-1, such as Figure 4 shown.

[0069] After completing the single safety measure operation and equipment information identification, hang the power operation sign on the corresponding operating equipment (for example: switch, valve), and use the handheld mobile terminal device 3 to automatically identify the electronic tag information. The handheld mobile terminal management APP 3-1 calls the background power equipment basic database 4 according to the electronic tag information to identify the corresponding sign information (including sign type and number), and enters it into the sign information column of the handheld mobile terminal management APP 3-1, such as Figure 5 shown.

[0070] After completing the execution of a safety measure and automatically identifying and entering the equipment information and identification plate information, repeat the above entry steps until all the operation contents of the operation task are completely identified and entered into the system, forming a complete operation task management system, and automatically uploading the relevant information to the background WEB server 5 for storage and management. The operation task status changes to "executing", such as Figure 6 shown.

[0071] Furthermore, the WEB server 5 is also used to batch create the operation contents of multiple operation tasks when the number of operation tasks required to be created before the power enterprise's production area equipment is maintained and overhauled is greater than or equal to A, wherein each operation content automatically displays the name of the power equipment.

[0072] It should be noted that before the power company carries out maintenance and overhaul of the equipment in the production area, if there are a large number of safety measures when entering the data, there is also the problem of heavy workload when using the handheld mobile terminal management APP3-1 to create operation tasks and automatically identify and record the implementation of maintenance and overhaul safety measures. Therefore, in this case, the back-end WEB server 5 can be used to create operation tasks, batch import operation tickets into the WEB server 5, use regular expressions to automatically filter and process operation ticket data, batch create N operation contents, and automatically display the name of the power equipment for each operation content. The status of the operation task changes to "not executed" as shown in the following figure. Figure 7 shown.

[0073] The operation task created by using the WEB server 5 already includes batch operation content, and the information is repeatedly entered (the power operation sign is hung on the corresponding operation equipment, and the handheld mobile terminal device 3 is used to automatically identify the electronic tag information. The handheld mobile terminal management APP3-1 calls the power equipment basic database 4 according to the electronic tag information to identify the corresponding sign information, and enters it into the sign information column of the handheld mobile terminal management APP3-1.) Until all the operation contents of the operation task are completely identified and entered into the system, a complete operation task management system is formed, and the relevant information is automatically uploaded to the WEB server 5 for storage and management. The status of the operation task changes to "executing". Figure 8 shown.

[0074] In the embodiment of the present disclosure, the handheld mobile terminal device 3 is further used to scan the RFID digital tag 2 of the power operation identification plate corresponding to the operation content when one or more operation contents in the operation task need to be restored during the maintenance process of the power equipment, and obtain the digital coding information of the RFID digital tag 2 of the power operation identification plate corresponding to the operation content;

[0075] The WEB server 5 is further used to modify the state of the electric power operation identification plate RFID digital tag 2 corresponding to the operation content based on the digital coding information of the electric power operation identification plate RFID digital tag 2 corresponding to the operation content.

[0076] It should be noted that during the maintenance of power equipment, if the equipment needs to be temporarily restored to operation, one or more of the operation contents in the operation task needs to be restored: that is, the operation equipment is turned on and the power operation sign is removed. At this time, the handheld mobile terminal device 3 is used to automatically identify the electronic tag information of the power operation sign, and the corresponding operation sign status (hanging, removal) can be marked in the power equipment basic database 4. If the safety measures need to be re-executed after the equipment is tested, the task is created and the sign is hung to realize the management of the power operation sign status. It is convenient for operation and maintenance personnel to quickly query and track the status of the power operation sign, such as Figure 9 shown.

[0077] In the embodiment of the present disclosure, the handheld mobile terminal device 3 is also used to scan the RFID digital tags 2 of each power operation identification plate after the power equipment maintenance is completed to obtain the digital coding information corresponding to each power operation identification plate RFID digital tag 2;

[0078] The WEB server 5 is further configured to modify the status of each power operation identification plate RFID digital tag 2 to be removed based on the digital coding information corresponding to each power operation identification plate RFID digital tag 2.

[0079] In the embodiment of the present disclosure, Figure 10As shown, the system further includes:

[0080] The judgment module 6 is used to judge whether the status of each power operation identification plate RFID digital tag 2 is removed after the power equipment maintenance is completed.

[0081] Further, such as Figure 10 As shown, the system further includes:

[0082] The alarm module 7 is used to control the equipment to lock and alarm if the status of the power operation identification plate RFID digital tag 2 is not removed after the power equipment maintenance is completed.

[0083] It should be noted that after the maintenance of the power equipment is completed, all the operation contents in the operation task need to be restored. During the execution process, the power equipment can be restored to the operating state one by one according to the operation ticket, and the identification plate can be removed. By using the handheld mobile terminal device 3 to automatically identify the RFID digital tag 2 of the power operation identification plate, the operation identification plate status can be marked as removed in the power equipment basic database 4. After completing the calibration of the removal information of the identification plates mounted for all operation contents, the operation task is automatically closed and turned into the closed state. If the identification plate corresponding to one of the operation contents is not removed, the system will lock and issue an alarm to remind that there is an identification plate that has not been removed. The locking function of the power operation identification plate is realized to prevent the omission of operating equipment and omission of removal of the plate when restoring safety measures.

[0084] To sum up, the intelligent management system for power operation signs proposed in this embodiment is based on RFID chip intelligent recognition technology. It uses electronic tags to digitally encode the equipment (switches, valves) that need to be operated in the production area of ​​the power enterprise, and uses electronic tags to digitally encode all power operation signs to ensure the uniqueness of the operating equipment and signs. Through intelligent management methods, the implementation of safety measures and the installation and removal of power operation signs are intelligently identified, tracked in real time and efficiently managed, thereby improving the safety and standardization of the power operation site, reducing the risk of loss and misuse of signs, and thus ensuring the safety and standardization of the power operation site.

[0085] Example 2

[0086] Figure 11 This is a flow chart of an intelligent management method for power operation signage according to one embodiment of the present application, such as Figure 11 As shown, the method includes:

[0087] Step F1: using a handheld mobile device to identify the RFID digital tags of each power device, obtaining the name information of each power device, and sending the name information of each power device to a power device basic database;

[0088] The handheld mobile device is an NFC-enabled phone or an RFID code scanning device.

[0089] Step F2: using a handheld mobile device to identify the RFID digital tags of each power operation identification sign, obtaining the operation information of each power device in operation, and sending the operation information of each power device in operation to the power equipment basic database;

[0090] Step F3: Create a work task using the handheld mobile terminal management APP set in the handheld mobile terminal device, and generate an RFID digital tag for the power work identification plate corresponding to the work task;

[0091] Step F4: When the staff completes the work, use a handheld mobile device to scan the RFID digital tag of the power work identification sign corresponding to the work task, obtain the equipment name information, sign type, and sign number corresponding to the work task, and update the power equipment basic database.

[0092] In an embodiment of the present disclosure, the method further includes:

[0093] The WEB server is used to store the equipment name information, nameplate type, and nameplate number corresponding to the operation task.

[0094] Furthermore, when the number of operation tasks to be created before the power enterprise carries out maintenance and overhaul of the equipment in the production area is greater than or equal to A, the operation contents of multiple operation tasks are created in batches using the WEB server.

[0095] In an embodiment of the present disclosure, the method further includes:

[0096] During the maintenance of power equipment, if one or more operation contents in the operation task need to be restored, the handheld mobile terminal device is used to scan the RFID digital tag of the power operation identification plate corresponding to the operation content to obtain the digital coding information of the RFID digital tag of the power operation identification plate corresponding to the operation content;

[0097] Based on the digital coding information of the electric power operation identification plate RFID digital tag corresponding to the operation content, the state of the electric power operation identification plate RFID digital tag corresponding to the operation content is modified.

[0098] In an embodiment of the present disclosure, the method further includes:

[0099] After the maintenance of the power equipment is completed, the RFID digital tags of each power operation identification plate are scanned by a handheld mobile device to obtain the digital coding information corresponding to the RFID digital tags of each power operation identification plate;

[0100] Based on the digital coding information corresponding to the RFID digital tag of each power operation identification plate, the status of each power operation identification plate RFID digital tag is modified to be removed.

[0101] In an embodiment of the present disclosure, the method further includes:

[0102] After the maintenance of the power equipment is completed, the judgment module is used to judge whether the status of the RFID digital tags of each power operation identification plate is removed.

[0103] If the status of the RFID digital tag on the power operation identification plate is not removed, the alarm module is used to control the device to lock and alarm.

[0104] Specifically, the detailed process of the method for intelligent management of power operation signboards provided by this embodiment is as follows: Figure 12 Shown, including:

[0105] Step 1: Digitally encode all equipment within the power company's production area. All equipment (switches, valves, etc.) that require operation within the power company's production area must be given dual names and numbers (for example: 500kV XX power plant first string contact XXXX switch, unit X volute water intake valve XXXX). Ensure the operating equipment has unique names. Attach RFID electronic tags to the equipment's operating panel or handle. Use a handheld mobile device (NFC-enabled phone, RFID scanner) to identify the electronic tag information and enter it into the power equipment basic database. Ensure that the power equipment name corresponds to the RFID digital tag, thereby achieving digital encoding of the equipment.

[0106] Step 2: Digitally encode all power operation signage within the power company's production area. Classify and number existing power operation signage within the power company's production area (for example, "No Closing 001" signage, "No Operation 009" signage), ensuring unique naming of the power operation signage. Attach RFID electronic tags to the power operation signage, use a handheld mobile device (NFC-enabled phone, RFID scanner) to identify the electronic tag information, and enter it into the power operation signage basic database, ensuring that the power operation signage name corresponds to the RFID digital tag, thereby achieving digital encoding of the signage.

[0107] Step 3: Before carrying out maintenance and overhaul of equipment in the production area of ​​a power enterprise, open the management app on a handheld mobile device (NFC-enabled phone, RFID scanning device), i.e., the handheld mobile management app, to create an operation task. This operation task is used to identify and automatically record the implementation of maintenance and overhaul safety measures and the installation of signage.

[0108] Step 4: After the handheld mobile device management app completes the creation of the operation task, the operation and maintenance personnel perform isolation safety measures according to the operation ticket and need to operate the equipment (for example, switches and valves). After completing the single safety measure operation, the handheld mobile device is used to automatically identify the electronic tag information. The management app calls the backend database based on the electronic tag information to identify the corresponding device information and automatically enters it into the management app device information column.

[0109] Step 5: After completing the single safety measure operation and equipment information identification, hang the power operation sign on the corresponding operating equipment (such as switches and valves), and use the handheld mobile device to automatically identify the electronic tag information. The management APP calls the backend database based on the electronic tag information to identify the corresponding sign information (including sign type and number), and enters it into the sign information column of the management APP

[0110] Step 6: After completing a safety measure and automatically identifying and entering the equipment and signage information, repeat steps 4-5 until all operations for the task are identified and entered into the system, forming a complete task management system. The relevant information is automatically uploaded to the backend web server for storage and management. The task status changes to "Executing."

[0111] Step 7: Before conducting maintenance and overhaul of equipment in a power company's production area, if there are a large number of safety measures during Steps 3-6, using a management app to create operation tasks and automatically identify and record the implementation of these maintenance and overhaul safety measures also presents a significant workload. Therefore, in this case, a backend web application can be used to create operation tasks, batch import operation tickets into the backend web application, and automatically filter and process the operation ticket data using regular expressions. Multiple operation items can be created in batches, with the power equipment name automatically displayed for each operation item. The operation task status then changes to "Not Executed."

[0112] Step 8: Use the backend web to create an operation task that already includes batch operation content. Repeat step 5. After completing the single safety measure operation and equipment information identification, hang the power operation sign on the corresponding operation equipment (for example, switches, valves), and use the handheld mobile device to automatically identify the electronic tag information. The management app calls the backend database based on the electronic tag information to identify the corresponding sign information (including sign type and number) and enter it into the management app sign information column. This process continues until all operation contents of the operation task are fully identified and entered into the system, forming a complete operation task management system, and the relevant information is automatically uploaded to the backend web server for storage and management. The status of the operation task changes to "Executing".

[0113] Step 9: During power equipment maintenance, if the equipment needs to be temporarily restored, one or more of the operations in the task will need to be restored: turning on the equipment and removing the power work sign. At this point, a handheld mobile device automatically identifies the electronic tag information on the power work sign and marks the corresponding sign status (installed or removed) in the backend database. If safety measures need to be re-implemented and the sign installed after the equipment is commissioned, follow Step 8 to manage the power work sign status. This allows operations and maintenance personnel to quickly query and track the status of the power work sign.

[0114] Step 10: After the maintenance of the power equipment is completed, all the operation contents in the operation task need to be restored. During the execution process, the power equipment can be restored to the operating state one by one according to the operation ticket, and the identification plate can be removed. By using a handheld mobile device to automatically identify the electronic tag information of the power operation identification plate, the status of the operation identification plate can be marked as removed in the back-end database. After completing the removal information calibration of the identification plates mounted for all operation contents, the operation task is automatically closed and turned into the closed state. If the identification plate corresponding to one of the operation contents is not removed, the system will lock and issue an alarm to remind that there is an identification plate that has not been removed. The locking function of the power operation identification plate is realized to prevent the omission of operating equipment and omission of removal of the plate when restoring safety measures.

[0115] Step 11: The power operation sign is managed intelligently throughout the entire process through the handheld mobile terminal management APP, back-end WEB, and database. Operation and maintenance personnel can use the back-end WEB database to implement operation tasks, operation equipment (such as switches, valves), and power operation sign (including sign type and number) query functions, which facilitates operation and maintenance personnel to quickly realize the positioning, tracing, status tracking, historical query, etc. of the power operation sign, greatly improving the work efficiency of operation and maintenance personnel.

[0116] The intelligent management method for electric power operation signboards proposed in this embodiment has the following advantages:

[0117] 1. Based on RFID chip intelligent recognition technology, it can quickly identify equipment and nameplates with 100% accuracy, and ensure the uniqueness of the operating equipment and nameplates. It automatically enters power equipment and nameplate data into the backend database, eliminating the need for manual transcription and significantly improving work efficiency.

[0118] 2. Through the intelligent management system platform, the implementation of safety measures and the installation and removal of power work signs are intelligently identified, tracked in real time, and efficiently managed, achieving full-cycle management of the installation of power work signs with traceability. This facilitates operations and maintenance personnel to quickly locate, trace, track status, and conduct historical inquiries on power work signs, significantly improving their management efficiency and reducing issues such as missed installation, missed removal, loss, mismatches, and misuse of power work signs during manual management.

[0119] 3. The patent of this invention has an anti-mistaken locking function, which locks the safety measures related to the maintenance operation task with the equipment and signboards one by one. After completing the operation task, all safety measures must be restored, the equipment operation must be completed, the signboard must be removed and identified using a handheld mobile device before the operation task closed loop can be unlocked to avoid missing safety measures, abnormal equipment operation caused by not removing the signboard, and even safety accidents or personal injury incidents.

[0120] In summary, the intelligent management method for power operation signboards proposed in this embodiment can greatly improve the safety and standardization of power operation sites, reduce the risk of signboard loss and misuse, and thus ensure the safety and standardization of power operation sites.
