Description

Technical Field

[0001] This invention relates to the field of wind turbine operation and maintenance technology, specifically to an intelligent management and control cabinet and operation and maintenance method for wind power operation and maintenance. Background Technology

[0002] The safe operation and maintenance of wind turbine generators is crucial for ensuring power generation efficiency and personnel safety. Currently, the following technical problems exist in wind power operation and maintenance: 1. The qualification verification of operation and maintenance personnel relies on manual management, which can easily lead to unlicensed operation and unauthorized personnel climbing towers, posing significant safety hazards; 2. The wearing of safety equipment and the use of safety warning signs lack a mandatory verification mechanism. Some operation and maintenance personnel omit safety measures for convenience, increasing the risk of accidents such as falls from heights and equipment misoperation; 3. The operation and maintenance process lacks closed-loop management. Work order execution, work process monitoring, and accountability traceability rely on manual recording, resulting in weak remote monitoring capabilities, untimely emergency response, and difficulty in quickly locating the cause of accidents. Summary of the Invention

[0003] This invention aims to overcome the shortcomings of existing technologies and provide an intelligent management and control cabinet and operation and maintenance method for wind power operation and maintenance. Through intelligent means, it realizes the mandatory standardization of operation and maintenance processes, the rigid implementation of safety measures, and remote visual management, solving problems such as lax qualification review, inadequate safety measures, and extensive process management in existing technologies.

[0004] To solve the above problems, the technical solution of the present invention is as follows: A wind power operation and maintenance intelligent management control cabinet includes a cabinet, an intelligent control unit, a work order receiving module, a personnel identification module, and a power control module. The intelligent control unit is electrically connected to the work order receiving module, the personnel identification module, and the power control module. The work order receiving module receives approved work order data transmitted from the SCADA system in the wind farm's central control room. The personnel identification module collects and verifies the identity information of operation and maintenance personnel and compares it with the information of the personnel specified on the work order. The power control module controls the power on / off status of the wind turbine climbing aid / elevator. After the personnel identification module verifies the information, the intelligent control unit sends an unlocking command to the power control module, allowing the climbing aid / elevator to be powered on.

[0005] Furthermore, it also includes a safety equipment detection module, which is electrically connected to the intelligent control unit and uses a visual sensor to detect in real time the compliance of the wearing of safety protective equipment such as safety helmets and safety belts by maintenance personnel.

[0006] Furthermore, it also includes a warning sign management module, which includes an RFID reader and a sign storage cabinet, electrically connected to the intelligent control unit, for detecting the receipt status of safety warning signs, the hanging status at designated locations, and the recycling status after use.

[0007] Furthermore, it also includes a display operation module, which is a touch LCD screen electrically connected to the intelligent control unit. It is used to dynamically display the core content of the work order, hazard source prompts, and a list of safety protection measures, and supports manual confirmation by maintenance personnel.

[0008] Furthermore, it also includes a remote communication module, which is an optical fiber or wireless communication module, electrically connected to the intelligent control unit to realize bidirectional data transmission with the SCADA system and centralized control platform in the wind farm control room.

[0009] Furthermore, it also includes an early warning module, which comprises an audible and visual alarm and a buzzer, electrically connected to the intelligent control unit. This module issues alarm signals and simultaneously reports to the centralized control platform when authentication fails, safety equipment is worn improperly, warning signs are used abnormally, or equipment malfunctions. It also includes a dual-redundant power supply module, comprising a main power supply and a backup lithium battery, providing stable power to all electrical modules within the cabinet.

[0010] Furthermore, it also includes a dual-redundant power supply module, which includes a main power supply and a backup lithium battery to provide stable power supply to each power module of the cabinet.

[0011] A maintenance method for a wind power operation and maintenance intelligent management control cabinet includes the following steps: S1: Work order transmission and initial locking. After the work order is approved by the person in charge of the work, the signatory, and the licensor at each level, it is transmitted to the intelligent control unit through the remote communication module of the SCADA system in the wind farm central control room. The intelligent control unit controls the power control module to disconnect the main power supply of the climbing aid / elevator and lock it. S2: Personnel identity verification. When maintenance personnel approach the control cabinet, the personnel identification module collects identity information through facial recognition or RFID card reading and compares it with the information of the personnel specified on the work order. If the comparison is successful, the process proceeds to the next step. If the comparison fails, the alarm module is triggered and the alarm is reported to the centralized control platform. S3: Safety equipment wearing detection. The safety equipment detection module collects images of maintenance personnel through visual sensors and uses computer vision algorithms to identify the wearing status of safety protective equipment. If the detection is qualified, it will proceed to the next step; otherwise, it will trigger an alarm from the early warning module. S4: Work order content confirmation. The operation module displays the maintenance location, work content, hazard sources and safety protection measures. After the maintenance personnel complete the confirmation through touch operation, they can proceed to the next step. S5: Warning sign collection and hanging verification. The intelligent control unit controls the opening of the sign storage cabinet door. Maintenance personnel collect the corresponding safety warning signs and hang them in the designated positions. The RFID reader checks the hanging compliance. If it complies, proceed to the next step. If it does not comply, the alarm module is triggered. S6: Climber / elevator unlocks. After the intelligent control unit receives the verification signals from each module, it controls the power control module to close the power supply of the climber / elevator, allowing maintenance personnel to climb the tower for inspection. S7: Maintenance execution and return, maintenance personnel return to the bottom of the tower after completing the maintenance task; S8: Warning sign recycling and system reset. Maintenance personnel return the warning signs to the sign storage cabinet. After the RFID reader detects and recycles the signs, the intelligent control unit controls each module to reset, and the power control module returns to its initial locked state.

[0012] Furthermore, in S2, the personnel identification module includes a face recognition unit and an RFID card reader unit.

[0013] Furthermore, in S3, the visual sensor of the safety equipment detection module uses a camera and is equipped with an infrared supplementary lighting device.

[0014] The beneficial effects of this invention are as follows: 1. This invention uses a personnel identification module to enforce the verification of the qualifications of maintenance personnel, thereby preventing unlicensed operation and solving the problem of lax qualification review in existing technologies; 2. The safety equipment detection module and warning sign management module form a rigid constraint on safety measures, ensuring that safety protective equipment is worn in compliance with regulations and that warning measures are implemented in place, thereby reducing the risk of accidents; 3. The closed-loop management of the entire process, combined with the remote communication module, enables visualized monitoring and data traceability of the operation and maintenance process, improves emergency response speed, allows for rapid identification of the cause after an accident, reduces manual management costs, and improves operation and maintenance efficiency; 4. Dual redundant power supply and harsh environment resistance design ensure stable operation of the equipment at wind power sites, with strong practicality and reliability.

[0017] 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.

[0018] A wind power operation and maintenance intelligent management control cabinet includes a cabinet, an intelligent control unit (S7-1500 PLC controller), a work order receiving module (HFBR-5981Z equipped with a photoelectric conversion interface), a personnel identification module (including a face recognition unit with an OV5640 camera and an RK3588 processor and an RC522 RFID card reader), and a power control module (including an MM440 series frequency converter drive unit and a MY2N-J relay). The intelligent control unit is electrically connected to the work order receiving module, the personnel identification module, and the power control module via a 485 bus or Ethernet, respectively. During operation, the work order receiving module first receives data from the SCADA system in the wind farm control room. The system transmits approved work order data containing maintenance tasks, safety procedures, and designated personnel information. The intelligent control unit parses and stores this data, then collects the identity information of the maintenance personnel through the personnel identification module and compares it bidirectionally with the designated personnel information on the work order. Once the comparison is successful, an unlocking command is sent to the power control module to control the relay to close, allowing the climbing aid / elevator to be powered on. In this way, the intelligent control unit coordinates the collaboration of various modules to achieve mandatory verification of the qualifications of maintenance personnel, eliminating unlicensed operations and unauthorized personnel climbing the tower from the source, and solving the safety hazards of existing technologies that rely on manual qualification verification and have lax control.

[0019] Furthermore, it also includes a safety equipment detection module. This module is electrically connected to the intelligent control unit via Ethernet and uses a vision sensor (IMX586 camera) to collect real-time images of the maintenance personnel's entire body. Based on the YOLOv8 computer vision algorithm, it analyzes and judges the compliance of wearing safety protective equipment such as safety helmets, safety belts, insulating gloves, and safety ropes. The image data collected by the vision sensor is transmitted to the intelligent control unit in real time. After algorithm analysis, if it is determined that the wearing is not in compliance with the rules, an alarm is triggered by the warning module, and subsequent processes are prohibited. This forms a rigid constraint on the wearing of safety equipment, prevents maintenance personnel from omitting safety measures for convenience, significantly reduces the risk of accidents such as falls from heights and electric shocks, and solves the problem of the lack of mandatory verification of the wearing of safety equipment in the existing technology.

[0020] Furthermore, the system includes a warning sign management module, which comprises an RFID reader (RC522) and a sign storage cabinet equipped with an electromagnetic lock (DS-K4H300), electrically connected to the intelligent control unit via a 485 bus. The RFID reader is installed inside the sign storage cabinet and at a designated hanging position on the tower. After personnel identification and safety equipment verification are passed, the intelligent control unit unlocks the electromagnetic lock. After maintenance personnel retrieve the warning sign, they must hang it in the designated position. The RFID reader detects that the hanging is compliant and sends a signal to the intelligent control unit. After maintenance is completed, the warning sign must be returned to the storage cabinet. The system reset is triggered only after the RFID reader detects the successful recycling. This achieves closed-loop management of the entire process of obtaining, hanging, and recycling safety warning signs, ensuring that warning measures are implemented effectively, preventing unauthorized personnel from accidentally touching equipment, and solving the safety hazard of lack of control over the use of warning signs in existing technologies.

[0021] Furthermore, it also includes a display operation module, which is a 10-inch touch LCD screen that supports multi-touch and has an IP65 waterproof and dustproof rating. It is electrically connected to the intelligent control unit via an HDMI interface. The intelligent control unit controls the LCD screen to dynamically display the core content of the work order, hazard warnings, a list of safety protection measures, and the verification status of each module in different areas. After carefully reading the information, the maintenance personnel click the "confirm" button via touch operation. Only after the confirmation signal is fed back to the intelligent control unit can the next step of the process be carried out. This ensures that the maintenance personnel are fully aware of the maintenance requirements and risks before the operation, reducing operational errors caused by unclear information. At the same time, the design to prevent accidental touches and resist harsh environments is adapted to the use scenarios of wind power sites.

[0022] Furthermore, it also includes a remote communication module, which is an armored optical cable or a 5G wireless communication module (EC20-A), electrically connected to the intelligent control unit via Ethernet; the optical cable transmission distance can reach more than 20km, and the 5G module supports full network connectivity; on the one hand, it receives work order data transmitted from the SCADA system in the wind farm central control room, and on the other hand, it reports personnel identity verification results, safety equipment detection status, alarm information, etc. to the centralized control platform in real time; its technical effect is to realize remote visual monitoring of the operation and maintenance process, break geographical restrictions, facilitate managers to grasp the work progress and equipment status in real time, improve emergency response speed, and solve the problems of weak remote monitoring capabilities and untimely emergency response in existing technologies.

[0023] Furthermore, it also includes an early warning module, which comprises an audible and visual alarm and a buzzer, electrically connected to the intelligent control unit via a relay. When situations such as identity verification failure, improper wearing of safety equipment, abnormal use of warning signs, or equipment malfunction occur, the intelligent control unit simultaneously triggers the audible and visual alarm (red flashing light + continuous alarm sound) and the buzzer, and simultaneously reports detailed information including alarm type, time, and location to the centralized control platform via a remote communication module; promptly issuing abnormality alerts to on-site maintenance personnel and remote management personnel, facilitating rapid problem location and handling measures, reducing the risk of accident escalation, and minimizing casualties and property losses.

[0024] Furthermore, it also includes a dual-redundant power supply module, which includes a main power supply (AC220V / 50Hz) and a backup lithium battery (18650 series group), equipped with a power management module (LTC4412). Under normal operating conditions, the main power supply powers each power module. When the main power supply is interrupted, the power management module realizes automatic switching between the main and backup power supplies with a switching time of ≤5ms. The backup lithium battery can provide power for no less than 8 hours. This ensures the stable operation of the equipment in the complex power supply environment of the wind power site, avoids the interruption of the operation and maintenance process or the failure of safety monitoring due to power outages, and ensures the continuity and reliability of the entire process control.

[0025] A maintenance method for a wind power operation and maintenance intelligent management control cabinet includes the following steps: S1. Work order approval and transmission lock: S12. Work Permit Initiation and Approval: Based on the wind turbine maintenance needs, maintenance personnel initiate a work permit application, specifying the turbine unit number to be maintained, the maintenance location (e.g., blades, gearbox, electrical control system), the work content, potential hazards (working at height, live equipment, mechanical injuries), and safety protection measures. The work permit requires a three-level approval process: review by the work supervisor, approval by the issuer, and authorization by the permitter, to ensure the compliance of the maintenance plan.

[0026] S12. Data Transmission and Initial Locking: Approved work order data (including the list of designated maintenance personnel, qualification information, and maintenance time window) is sent by the SCADA system in the wind farm's central control room to the intelligent management control cabinet of the corresponding unit via a remote communication module (fiber optic cable or 5G wireless module) at a stable transmission rate. After receiving the data, the intelligent control unit immediately parses and stores it in its local memory, and simultaneously issues a "locking command" to the power control module, controlling the frequency converter drive unit to disconnect the main power supply to the climbing aid / elevator, and keeping the relay in the open state. At this time, the climbing aid / elevator cannot start, thus preventing unauthorized climbing or misoperation from the source.

[0027] S2. Operations and maintenance personnel authentication: S21. Personnel arrival trigger detection: When maintenance personnel arrive at the control cabinet at the bottom of the tower, the personnel identification module is automatically activated, and a dual verification mechanism (face recognition + RFID card reading) is started to adapt to the needs of different operation scenarios.

[0028] S22. Identity Information Collection and Comparison: Facial recognition unit: The camera (equipped with an infrared fill light device) captures facial images of maintenance personnel, extracts facial features through computer vision algorithms, and compares them with the designated personnel feature database pre-stored in the work order; Radio frequency card reading unit: When maintenance personnel present an radio frequency card, the card reading module reads the identity information on the card and performs a secondary comparison with the pre-stored qualification information.

[0029] S23. Verification Result Processing: If both verifications pass, the intelligent control unit records the verification time and personnel information, allowing the process to proceed to the next step; if either verification fails (e.g., non-designated personnel, mismatch of identity information), the intelligent control unit immediately triggers the early warning module, the audible and visual alarm sounds, the buzzer responds synchronously, and at the same time, the alarm information (including alarm type, time, and unit number) is reported to the wind farm centralized control platform in real time through the remote communication module, prohibiting subsequent operations.

[0030] S3. Safety Equipment Wearing Detection: S31. Image Acquisition and Algorithm Recognition: After identity verification, the safety equipment detection module automatically starts, and the visual sensor (camera + infrared supplementary lighting device) acquires full-body images of the maintenance personnel. The acquired image data is transmitted to the intelligent control unit in real time, and the YOLOv8 computer vision algorithm is used to accurately identify the wearing status of core protective equipment such as safety helmets, safety belts, insulating gloves, and safety ropes, focusing on key items such as "whether the safety helmet is worn properly, whether the safety belt buckle is fastened, and whether the insulating gloves are worn correctly".

[0031] S32. Detection Result Judgment: If the algorithm determines that all protective equipment is worn in compliance with regulations, the intelligent control unit sends an "allow confirmation" signal to the display operation module; if it detects omissions (such as not wearing a safety helmet) or improper wearing (such as not fastening the seat belt), the intelligent control unit triggers an alarm from the warning module, and at the same time clearly indicates the violation on the display operation module (such as "Please wear a safety helmet" "Please fasten the seat belt buckle"). After the maintenance personnel make corrections, they need to re-trigger the detection until it is qualified before proceeding to the next step.

[0032] S4. Confirmation of Work Order Details: S41. Information Display and Manual Confirmation: After the safety equipment passes inspection, the operation module automatically displays work order information by area: A. Details of the unit and location to be repaired; B. List of hazards and risk levels; C. Required safety protection measures (such as "power off and tagging," "double-hook safety belts required for high-altitude operations"); D. Emergency contact person and rescue phone number. Maintenance personnel must carefully read all information and, after confirming full understanding, click the "Confirm Understanding and Commitment to Compliance" button on the touchscreen. This confirms that the operation record is automatically stored in the local memory of the intelligent control unit and simultaneously uploaded to the centralized control platform for record-keeping.

[0033] S42. Unconfirmed Processing: If the maintenance personnel do not perform a confirmation operation (such as skipping directly), the operation module will continue to lock the subsequent process, and the intelligent control unit will not issue a warning sign collection instruction to ensure that the maintenance personnel "operate after being informed".

[0034] S5. Warning sign collection, hanging verification: S51. Storage Cabinet Unlocking and Retrieval: After the work order is confirmed, the intelligent control unit sends an "unlock command" to the warning sign management module. The electromagnetic lock of the sign storage cabinet automatically unlocks, and maintenance personnel can retrieve the corresponding safety warning signs according to the work order (such as "Equipment under maintenance, do not approach," "Working at height, be careful," "Stop, high voltage danger"). The storage cabinet has a built-in counting sensor to record the number and type of warning signs retrieved to avoid omissions.

[0035] S52. Hanging and Compliance Check: After receiving the warning signs, maintenance personnel must hang them in the designated locations (such as at the tower entrance, next to the power switch in the maintenance area, or at the start of the ladder) according to the work order requirements. Pre-installed RFID readers at each hanging location will detect in real time whether the warning signs are properly hung. If a warning sign is detected and the location matches, a "Hanging Compliance" signal will be sent to the intelligent control unit. If no sign is detected (e.g., not hung) or the location is mismatched (e.g., hung in the wrong area), the intelligent control unit will trigger an alarm from the warning module, displaying the message "Warning sign not hung in the designated location" from the operation module. Maintenance personnel must then adjust the sign and re-pass the RFID check until compliance is achieved.

[0036] S6. Climber / Elevator Unlock: S61. Verification Signal Summary: The intelligent control unit summarizes the verification status of each module in real time. Only when all conditions are met, such as "work order received, identity verification passed, safety equipment inspection qualified, work order confirmed, and warning sign hanging compliant", is it determined to be "full process verification passed" and an "unlock permission" instruction is generated.

[0037] S62. Power Unlocking and Power-On: The intelligent control unit sends an unlocking command to the power control module, controlling the relay to close. The frequency converter drive unit outputs 0-380V compatible three-phase AC power, officially connecting the power supply to the climber / elevator. At this time, the intelligent control unit reports the "tower access permission" status to the centralized control platform via the remote communication module, including personnel information, unlocking time, verification results, and other details, facilitating real-time monitoring by management personnel. Maintenance personnel can then activate the climber / elevator and climb the tower to perform maintenance tasks according to specifications.

[0038] S7. Inspection Execution and Return: S71. Maintenance Process Monitoring: After maintenance personnel climb the tower, the intelligent control unit continuously receives real-time instructions from the wind farm's centralized control platform via the remote communication module. In case of an emergency (such as sudden equipment failure or extreme weather), the centralized control platform can issue an "emergency shutdown" command. The intelligent control unit immediately sends a power-off command to the power control module to disconnect the power supply to the climbing aid / elevator, preventing the danger from escalating. Simultaneously, the remote communication module maintains two-way communication, allowing maintenance personnel to report the situation to the centralized control platform via an emergency call device inside the tower (optional, linked to the control cabinet).

[0039] S72. Return after maintenance: After completing the maintenance tasks (such as troubleshooting, component replacement, and parameter debugging) according to the work order requirements, the maintenance personnel return to the bottom of the tower via the climbing aid / elevator to prepare for the subsequent finishing process.

[0040] S8. Warning sign retrieval and system reset: S81. Warning Sign Recycling Detection: After returning, maintenance personnel must remove all hanging safety warning signs, return them to the sign storage cabinet, and close the cabinet door. The RFID reader built into the storage cabinet will detect that all warning signs have been recycled and send a "recycling complete" signal to the intelligent control unit. If any warning signs remain unrecycled, the intelligent control unit will trigger an alarm from the warning module, prompting "Please recycle all warning signs."

[0041] S82. System Reset and Data Archiving: After confirming that all warning signs have been retrieved, the intelligent control unit initiates the "system reset" process: A. Sends a command to the power control module to disconnect the power supply to the climbing aid / elevator and relock it; B. Controls each module (personnel identification, safety detection, display operation) to restore its initial state; C. Encrypts and stores the entire process data of this operation and maintenance (including work ticket information, personnel verification records, safety detection results, tower climbing / return time, and warning sign issuance and retrieval records) to the local storage, and simultaneously uploads it to the wind farm centralized control platform for archiving through the remote communication module, forming a traceable operation and maintenance closed loop.

[0042] The entire working process is centered on the intelligent control unit. Through the coordinated linkage of various functional modules, it enforces "qualification compliance, equipment compliance, and process compliance" without the need for manual intervention and control. This not only eliminates hidden dangers such as unlicensed operation and omissions in safety measures, but also realizes visualized monitoring and accountability of the operation and maintenance process, making it fully adaptable to the harsh environment and safety management needs of wind power sites.

[0043] The embodiments described in this specification are merely examples of implementations of the inventive concept. The scope of protection of this invention should not be considered as limited to the specific forms stated in the embodiments. The scope of protection of this invention also extends to equivalent technical means that can be conceived by those skilled in the art based on the inventive concept.
