If it is determined that there is no ticket for approaching a wind turbine or a booster station, the process goes to S6. If it is determined that there is a corresponding work ticket or operation ticket, the process goes to S7. S6. Conduct VHF communication and sound and light warnings for the ship, start video surveillance, and centrally control the central control screen for early warning; S7: The central control system issues a command to allow the ship to approach the wind turbine or booster station, and transfers to S6; S8. After the work team arrives at the wind turbine or booster station platform, the monitoring system will perform face recognition and comparison on the work team. If the match is successful, the work is allowed to proceed; S9. After the work team arrives at the wind turbine or booster station platform, the personnel climbing over the railing monitoring system will be activated at the same time to ensure that people falling into the water are discovered as soon as possible. The monitoring screen will be recorded in real time. After the on-duty personnel are warned and determine that people have fallen into the water, they will immediately notify rescue operations.

[0012] In the preferred solution, when the ship is in the third-level warning area, the second-level warning area and the first-level warning area, the signal colors of the central control system are blue, yellow and red, corresponding to the third-level warning, the second-level warning and the first-level warning respectively; When a ship stays in the secondary warning area for a long time, the signal color of the central control system changes from yellow to red, and the ship enters the first-level warning area in advance.

[0013] The present invention provides a comprehensive monitoring and early warning system method for an offshore wind farm, and the system includes a power production management system, a data acquisition unit, a central control system and an early warning system.

After each project department has reviewed the incoming ship materials, it will enter the ship's AIS, the names and faces of the work team members and supervisors and other related information into the system. The person in charge of the work adds the name of the ship the work team is on and the number of the working wind turbine in the two-ticket filling, and the system automatically matches the AIS information of the ship. The content of the work ticket includes the planned start and end time of the work. If there is an extension, it can be handled in the power production management system, and the system will simultaneously extend the time when the ship can approach the wind turbine.

[0016] Through the two tickets and the relevant work information of the incoming ships in the power production management system, the supervision and management of the incoming work team is guaranteed. The face recognition of the work team is used to ensure that the ticket-holding work team members are matched with the two-ticket staff, to ensure the safety of personnel and prevent production safety accidents caused by unticketed operations.

The alarm information of the early warning system is also fed back to the central control screen of the control center for the duty personnel to view. The early warning system includes text message notification, sound and light alarm and VHF communication module.

[0018] The integrated monitoring and early warning system for offshore wind farms achieves all-round monitoring of the internal and external environment of wind farms by integrating power production management, data collection, central control analysis and early warning functions. The system can collect and analyze data from ships, personnel and key infrastructure in real time, automatically assess potential risks, and promptly notify relevant personnel to take countermeasures through multi-level warning area settings and multiple early warning methods, effectively avoiding the occurrence of safety accidents. It not only improves the operational efficiency and safety of wind farms, but also provides a more reliable working environment for staff, ensuring the stable operation of offshore wind power facilities.

[0019] In one embodiment, the data acquisition unit specifically includes: AIS module, which is interactively connected with the central control system, is used to obtain ship information and send the ship information to the central control system. The ship information includes: static information, dynamic information, voyage information and safety information; A radar positioning device is interactively connected with the central control system to obtain the distance and direction of the ship entering the wind farm area and send the distance and direction of the ship to the central control system; The mobile base station is interactively connected with the central control system to provide network and communication for wind farm equipment and users. At the same time, users will receive SMS notifications when they enter the wind farm area.

[0020] The infrared & microwave monitoring module is interactively connected with the central control system. The infrared and microwave sensors are used to monitor ships entering the first-level warning area and small fishing boats without AIS modules installed, and send early warning signals to the central control system.

[0021] The electronic nautical chart has three levels of warning areas, which are the first-level warning area, the second-level warning area and the third-level warning area from the inside to the outside. The signal colors displayed in the central control system are red, yellow and blue respectively.

[0022] Video surveillance is connected to the central control system. When the central control system analyzes the ship entering the secondary warning area, it will keep tracking it. When the ship enters the primary warning area, it will conduct real-time tracking and recording to effectively protect the wind farm units.

[0023] The face recognition module is connected to the central control system and is used to match the target to be detected with the facial information of the working team members in the power production management system.

[0024] The monitoring of people climbing over the fence is connected to the central control system. The monitoring screen is analyzed in real time through algorithms, and a virtual warning fence area is set. Once a person is detected climbing over the fence, the system will immediately start the snapshot function and simultaneously push the alarm information to the central control system. Real-time monitoring of the members of the work team who have been allowed to work can prevent accidents of people falling into the water; combined with artificial intelligence, the monitoring of people climbing over the fence is used to ensure the safety of personnel, and the occurrence of people falling into the water can be discovered in the first time and an early warning can be issued to notify rescue.

[0025] Submarine cable online monitoring is used to check the status of submarine cables, including temperature monitoring module, stress monitoring module, disturbance monitoring module, AIS positioning module and fault positioning module.

[0026] The vibration monitoring of fans and booster stations is connected to the central control system to conduct real-time monitoring of the fan and booster station pile foundations to ensure the safety of the foundation structure.

[0027] The data acquisition unit integrates a variety of advanced technologies and equipment, which can comprehensively monitor the safety of the surrounding environment and internal facilities of the wind farm. The AIS module works in conjunction with the radar positioning device to ensure that the location information of large ships and small fishing boats without AIS can be accurately captured; the mobile base station not only meets the network requirements of wind farm equipment and communication support for operators, but also sends safety reminder text messages to personnel entering the wind farm; the infrared & microwave monitoring module can identify small ships entering the warning area, making up for the problem of insufficient AIS coverage; the electronic chart combined with the design of the three-level warning area enables the central control system to respond quickly according to different risk levels; the video monitoring system can start the tracking mode when the ship approaches, providing additional security for the wind farm; the face recognition module and the monitoring of personnel climbing over the fence ensure the identity authentication and behavior monitoring of the staff, and use artificial intelligence technology to detect abnormal behavior in real time, such as emergency situations such as people falling into the water; the online monitoring of submarine cables and the vibration monitoring of wind turbines and booster stations further strengthen the protection of critical infrastructure. These measures work together to significantly improve the safety and operational efficiency of wind farms, reduce potential safety hazards, and provide a solid foundation for the continuous and stable operation of wind farms.

[0028] The data acquisition unit collects online monitoring data of submarine cables and vibration monitoring data of wind turbines and booster stations. Once the submarine cable is cut due to the anchoring of the ship, the fault point can be located in time according to the ship positioning information and online monitoring data of the submarine cable, and the video recording of the cameras of the surrounding units can be linked to ensure the rapid implementation of the subsequent submarine cable repair work. The vibration monitoring of wind turbines and booster stations further strengthens the safety monitoring function of offshore wind farms.

[0029] The electronic chart divides three warning areas, and conducts comprehensive 24-hour online automatic monitoring through AIS module, radar positioning device, mobile base station, infrared & microwave monitoring module and video monitoring to accurately locate the position of ships entering the wind farm and related information. The infrared & microwave monitoring module can monitor small fishing boats without AIS module and radar positioning device within 10m of wind turbines and booster stations to prevent fishermen from entering wind turbines and booster stations, causing equipment damage or safety accidents.

[0030] In one embodiment, three levels of warning areas are set according to the electronic nautical chart, specifically including: The first-level warning area is within 10m outside the infrared & microwave monitoring module controlled fan or booster station; The secondary warning area is the submarine cable laying area in the wind farm area, which is monitored in real time through AIS modules and radar positioning devices; The third-level warning area is the wind farm area.

[0031] By setting up three levels of warning areas, the integrated monitoring and early warning system for offshore wind farms can carry out targeted monitoring and management of areas with different risk levels. The first-level warning area is within 10 meters outside the wind turbine or booster station, using infrared & microwave monitoring modules to identify close-range threats; the second-level warning area covers the submarine cable laying area, using AIS modules and radar positioning devices to monitor ship activities in real time to prevent damage to the submarine cable; the third-level warning area covers the entire wind farm and provides comprehensive safety protection. This multi-level warning system helps to detect and respond to potential risks in a timely manner, ensure the safe operation of wind farm equipment, and also protect the lives of staff, improving the reliability and efficiency of overall operations.

[0032] In one embodiment, the face recognition module has a specific process as follows: after the work team members arrive at the wind turbine or booster station platform, they are matched through the face information of the work team members in the power production management system. Only after the match is successful can safety measures be implemented to carry out work.

[0033] The facial recognition module matches the facial information of on-site staff with the pre-stored data in the power production management system to ensure that only authorized personnel can perform corresponding work tasks, effectively preventing unauthorized personnel from entering key areas, enhancing the safety management of wind farms, and also improving work efficiency and reliability.

[0034] In one embodiment, during the online monitoring of the submarine cable, when a ship enters the secondary warning area, the signal feedback central control system reminds the on-duty personnel to pay attention to the submarine cable monitoring system, and at the same time activates the early warning system to warn foreign ships not to drop anchor; when the ship drops anchor, the submarine cable online monitoring system monitors the anchoring point in real time to ensure that the fault point can be accurately located after the submarine cable anchor breaks.

[0035] The submarine cable online monitoring system can timely remind the duty personnel to pay attention to the safety of the submarine cable by real-time monitoring of ships entering the secondary warning area, and inform the ship not to drop anchor through the early warning system. When the ship stays in the secondary warning area for a long time (more than 10 minutes), the signal color display of the central control system changes from yellow to red, VHF communication and sound and light warning are carried out for the ship, video monitoring and real-time tracking are turned on, and the central control screen is warned, so as to effectively prevent the damage of the submarine cable. Once the ship drops anchor and damages the submarine cable, the system can monitor and accurately locate the possible submarine cable fault points in real time, quickly initiate emergency response measures, reduce maintenance time and cost, ensure the normal operation of the offshore wind farm, and avoid power transmission interruption or other safety accidents caused by submarine cable damage. This not only improves the safety of the submarine cable, but also enhances the reliability and operational efficiency of the entire wind farm.

[0036] In one embodiment, the early warning system includes SMS notification, VHF communication module and sound and light alarm, specifically: SMS notification: Use the mobile base station of the wind farm to send SMS messages to the holders of the three-network communication equipment entering the wind farm area, reminding them that "you have entered the XXX wind farm and are prohibited from anchoring or entering the power facilities without a ticket" and other related content; VHF communication module, for instant communication and broadcasting voice alarm information to surrounding ships; Sound and light alarm, use sound and light alarm, turn on strong high-pitched broadcast and strong light to remind ships to leave as soon as possible.

[0037] SMS notification, high-pitched broadcast and strong light irradiation can notify and warn ships in time. The VHF communication module can communicate and warn ships, and the duty personnel can obtain the relevant early warning signals transmitted to the central control screen of the centralized control center in the first time. For ships that cannot be stopped, the background receives the signal, and after obtaining the ship information, the duty personnel contact the maritime department to carry out work and start video surveillance recording at the same time.

[0038] The early warning system can immediately alert the crew and shore-based personnel when a ship enters a dangerous area of ​​a wind farm through SMS notifications, VHF communication modules, and sound and light alarms. SMS notifications ensure that personnel entering the area are aware of relevant regulations, the VHF communication module can immediately warn surrounding ships, and the sound and light alarm drives away ships through high-pitched broadcasts and strong light illumination. These measures ensure that the on-duty personnel can receive early warning information on the central control screen of the centralized control center as soon as possible, and quickly contact the maritime department for intervention in situations that cannot be stopped, and at the same time start video surveillance to record the on-site situation, effectively preventing safety hazards and ensuring the safe operation of the wind farm.

[0039] Example 2 Further illustrate with reference to Example 1, Figure 2 As shown, the present invention also provides a comprehensive monitoring and early warning method for an offshore wind farm, comprising the following steps: S1: The ship enters the third-level warning area. At this time, the signal color of the central control system is blue, and the ship is reminded through SMS notification. The AIS information of the incoming ship in the power production management system is used to determine whether the ship is a construction or maintenance ship entering the site through the central control system. If it is determined to be an external ship, it will go to S2. If it is determined to be a construction or maintenance ship entering the site, it will go to S3; S2. For foreign ships, the specific operations are as follows: When a ship enters the secondary warning area, the signal color of the central control system will be displayed in yellow, and the ship will be reminded through VHF communication and the central control screen will be used for reminder; When a ship stays in the secondary warning area for a long time, in this embodiment, if the ship stays for more than 10 minutes, the signal color display of the central control system changes from yellow to red, VHF communication and sound and light warning are carried out for the ship, video monitoring and real-time tracking are turned on, and the central control screen is warned; When a ship enters the Level 1 warning zone, the signal color of the central control system will be red, VHF communication and sound and light warning will be carried out to the ship, video surveillance and real-time tracking will be turned on, and the central control screen will issue an early warning; S3. For ships entering the site for construction or operation and maintenance, the specific operations are as follows: When entering the third-level warning area, the central control system uses the power production management system to determine whether the ship has two work tasks. If it is determined that there are no two work tasks for the wind farm, it will go to S4. If it is determined that there are two work tasks for the wind farm, it will go to S5. S4. Conduct VHF communication and sound and light warnings for the ship, start video surveillance, and centrally control the central control screen for early warning; S5. When a ship enters the secondary warning area, the centralized control screen reminds and displays the ship's trajectory. When a ship stays in the secondary warning area for a long time, in this embodiment, the ship stays for more than 10 minutes, the central control system signal color display changes from yellow to red, and the ship is reminded by VHF communication, and the centralized control screen is warned; When the ship enters the first-level warning area, the signal color of the central control system is displayed in red, and the centralized control screen reminds and displays the ship's trajectory. The expected task location is determined according to the ship's trajectory. The central control system determines whether the work team on the ship holds a work ticket or operation ticket corresponding to the expected task location, that is, a work ticket and an operation ticket for the wind turbine or booster station. If it is determined that there is no ticket for the wind turbine or booster station, go to S6. If it is determined that there is a corresponding work ticket or operation ticket, go to S7. S6. Conduct VHF communication and sound and light warnings for the ship, start video surveillance, and centrally control the central control screen for early warning; S7: The central control system issues a command to allow the ship to approach the wind turbine or booster station, and transfers to S6; S8. After the work team arrives at the wind turbine or booster station platform, the monitoring system will perform face recognition and comparison on the work team. If the match is successful, the work is allowed to proceed; S9. After the work team arrives at the wind turbine or booster station platform, the personnel climbing over the railing monitoring system will be activated at the same time to ensure that people falling into the water are discovered as soon as possible. The monitoring screen will be recorded in real time. After the on-duty personnel are warned and determine that people have fallen into the water, they will immediately notify rescue operations.

[0040] In the preferred solution, when the ship is in the third-level warning area, the second-level warning area and the first-level warning area, the signal colors of the central control system are blue, yellow and red, corresponding to the third-level warning, the second-level warning and the first-level warning respectively; When a ship stays in the secondary warning area for a long time, the signal color of the central control system changes from yellow to red, and the ship enters the first-level warning area in advance.

[0041] When a ship enters the third-level warning area, an early warning signal is triggered. Through the AIS information of the incoming ship in the power production management system, the central control system determines whether the ship is a construction or operation and maintenance ship.

[0042] When the ship is a foreign ship, the ship personnel will be reminded through SMS notification that "this area is XXX offshore wind farm, anchoring is prohibited". When the ship enters the second-level warning area, the ship will be reminded by VHF communication, and the central control screen will remind and display the ship's trajectory; when the ship stays in the second-level warning area for a long time (more than 10 minutes), the ship will be warned by VHF communication and sound and light, video monitoring and real-time tracking will be turned on, and the central control screen will be warned. When the ship enters the first-level warning area, the ship will be warned by VHF communication and sound and light, and monitoring video will be turned on. At the same time, the monitoring screen of the centralized control center will jump to the main screen of the central control, and the duty personnel will be warned.

[0043] The central control system determines that the ship is a construction or maintenance ship. When the ship enters the third-level warning area, the central control system uses the power production management system to determine whether the ship has two work tasks. If it is determined that there are no two work tasks for the wind farm, VHF communication and sound and light warnings are carried out on the ship, video monitoring is turned on, and the central control screen is warned. When the ship enters the second-level warning area, the central control screen reminds and displays the ship's trajectory. When the ship stays in the second-level warning area for a long time (more than 10 minutes), VHF communication reminders are carried out on the ship, and the central control screen is warned. When the ship enters the first-level warning area, the central control system determines whether the wind turbine or booster station that the work team on the ship is leaning against has an operation task corresponding to the work ticket and operation ticket. If there is no ticket to lean against the wind turbine, VHF communication and sound and light warnings are carried out on the ship, and monitoring video is turned on. At the same time, the monitoring screen of the centralized control center jumps to the central control main screen to warn the duty personnel.
