[0008] In order to allow those skilled in the art to better understand the technical solutions of one or more embodiments in this specification, the technical solutions are hereinafter described clearly and completely with reference to the drawings of one or more embodiments in this specification, and it is to be understood that the described embodiments are only a part of the embodiments in this specification, and not all of the embodiments. All other embodiments obtained by those skilled in the art without creative labor based on one or more embodiments in this specification shall all belong to the protection scope of the present invention.

[0009] Example of the system According to an embodiment of the present invention, an offshore wind farm alarm system based on the cooperation of AIS, radar and a camera platform is provided. FIG. 1 is a schematic diagram of an offshore wind farm alarm system based on the cooperation of AIS, radar and a camera platform according to an embodiment of the present invention. As shown in FIG. 1, the offshore wind farm alarm system based on the cooperation of AIS, radar and a camera platform according to an embodiment of the present invention specifically includes: The system includes a radar system 12, an AIS system 11, a head system 13, a master control system 10, a display device 14, and an alarm system 15. the radar system 12 is interactively connected to the master control system 10, for acquiring the distance and direction of a vessel entering the wind farm warning area, and for transmitting the distance and direction of the vessel to the master control system 10; Here, the system is connected to two types of radar: a coastal radar and a boat radar. The coastal radar is characterized by a long detectable distance, a large detection area, and high identification accuracy, and can provide the system with the accurate distance and direction of a ship target that has entered the wind farm warning area, while the boat radar has a shorter detection distance and smaller detection range than the coastal radar, and is installed in the wind farm as a device to supplement the blind spots of the coastal radar, and can cooperate with the coastal radar to provide the system with information such as the distance and direction of a ship target that has entered the wind farm warning area.

[0010] The AIS system 11 is interactively connected to the master control system 10 to acquire ship information including static information, dynamic information, navigation information, and safety information, and transmit the ship information to the master control system 10. The static information of the ship acquired by the AIS system 11 includes the ship's name, MMSI, captain, ship's width, and ship type, and the dynamic information of the ship acquired by the AIS system 11 includes the sailing direction, sailing speed, latitude, longitude, and sailing direction status.

[0011] the platform system 13 is interactively connected to the master control system 10 and is for tracking a target vessel under the control of the master control system 10; The master control system 10 is connected to the radar system 12, the AIS system 11, the platform system 13, the display device 14, and the alarm system 15, and is for receiving the distance and direction of the ship transmitted from the radar system 12, receiving the ship information transmitted from the AIS system, driving the platform system 13 to track the ship according to the distance, direction and ship information of the ship, and generating warning information for the ship that has entered the wind power plant according to the distance, direction and ship information of the ship, and transmitting the warning information to the alarm system 15. A display device 14 is connected to the master control system 10 and is used to display a screen of the ship's movement trajectory; The warning system 15 is connected to the master control system 10, for warning the vessel according to the warning information.

[0012] The marine warning system based on the cooperation of AIS, radar and the camera platform system further includes an audio warning device 16, which is connected to the master control system 10 and is for issuing an audio warning to ships that have entered the wind farm according to the warning information. When the personnel on duty pay attention to the warning, they can use a VHF very high frequency voice to warn the ships that have entered the alert area, and the VHF voice is automatically stored by the VHF system as one of the means of collecting evidence.

[0013] The marine warning system based on the cooperation of the AIS, the radar and the camera platform system further includes a searchlight 17, which is connected to the master control system 10 and is for shining a strong light on any ship that enters the wind farm in accordance with the warning information.

[0014] The AIS target information acquired by the AIS connection software and the radar target information acquired by the radar acquisition and tracking processing software are integrated and calibrated in time and space, and then related processing is carried out to realize the fusion of radar targets and AIS targets, and the fused data is comprehensively displayed in the situation display subsystem.

[0015] The intelligent alarm software can alert ships violating the rules according to the pre-defined area and ship navigation rules, alert people in distress at sea, and alert the main following ships. The alarm method can be selected from sound, color, text, and pop-up window prompts, and employees can choose from a variety of alarm methods according to the type of dangerous situation they set.

[0016] When tracking a target in a coordinated manner using video, the system can automatically calculate the rotation angle of the camera head according to the target's position information, and drive the camera head to track the target in coordination. Using the dynamic information of each ship obtained from the AIS / radar system (mainly the position information of the ship's latitude and longitude coordinates) and the camera head monitoring point system information (mainly the position information of the monitoring point's latitude and longitude coordinates), the coordinated tracking algorithm is used to calculate and drive the camera head and lens to operate (driving the rotation speed and steering of the camera head, and driving the focal length of the lens), so that coordination between the AIS, radar, and camera head is achieved.

[0017] The video analysis linkage function does not rely on AIS or radar signals. When an employee clicks on the target vessel on the video screen of the display system, the system can automatically enlarge and center the target vessel. When the target vessel is sailing, tracking of the target vessel throughout its entire voyage can be achieved without the need for employee intervention, and the target vessel will always be automatically displayed in the center of the monitoring screen.

[0018] When a target enters the defense zone and is detected by the system, it will immediately sound an alarm and simultaneously feed back the target's latitude and longitude information to the system. The system calculates the distance between the target and the monitoring area according to the target's latitude and longitude information, and when the distance is less than 1000 meters, the system will sound an alarm, and at the same time, it will coordinate with the platform to track the target during the entire voyage and take snapshots and videos to collect evidence. The staff on duty will use VHF voice to give an audio warning to the entering ship, and if the warning fails, they can use a searchlight to shine a strong light on the entering ship to make it leave.

[0019] Application of the embodiments of the present invention has the following beneficial effects:

[0020] The distance and direction of the ship is obtained using radar, and ship information is obtained using AIS. The camera head is driven to track the invading ship according to the distance, direction and ship information of the ship, thereby achieving coordination between the AIS, radar and camera head, thereby improving the monitoring accuracy of the system. At the same time, a warning system is used to warn ships that have invaded the wind farm and have them leave, thereby improving the safety of the offshore wind farm.

[0023] The intelligent alarm software can alert ships violating the rules according to the pre-defined area and ship navigation rules, alert people in distress at sea, and alert the main following ships. The alarm method can be selected from sound, color, text, and pop-up window prompts, and employees can choose from a variety of alarm methods according to the type of dangerous situation they set.

[0024] When tracking a target in a coordinated manner using video, the system can automatically calculate the rotation angle of the camera head according to the target's position information, and drive the camera head to track the target in coordination. Using the dynamic information of each ship obtained from the AIS / radar system (mainly the position information of the ship's latitude and longitude coordinates) and the camera head monitoring point system information (mainly the position information of the monitoring point's latitude and longitude coordinates), the coordinated tracking algorithm is used to calculate and drive the camera head and lens to operate (driving the rotation speed and steering of the camera head, and driving the focal length of the lens), so that coordination between the AIS, radar, and camera head is achieved.

[0025] The video analysis linkage function does not rely on AIS or radar signals. When an employee clicks on the target vessel on the video screen of the display system, the system can automatically enlarge and center the target vessel. When the target vessel is sailing, tracking of the target vessel throughout its entire voyage can be achieved without the need for employee intervention, and the target vessel will always be automatically displayed in the center of the monitoring screen.

[0026] When a target enters the defense zone and is detected by the system, it will immediately sound an alarm and simultaneously feed back the target's latitude and longitude information to the system.
