Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of offshore wind farm equipment monitoring, and in particular to a method and device for ship identification and offshore wind power ship monitoring. Background Art
[0002] The installed capacity of offshore wind turbines in my country is constantly increasing, and in many cases, submarine cables are needed to achieve a unique mode of power transmission. With the increasing marine development activities, mechanical damage accidents to submarine cables caused by aquaculture, fishing nets, anchors, etc. in the sea area occur from time to time. Therefore, in order to protect the safety of submarine cables and offshore wind turbines, it is necessary to monitor ships that threaten offshore wind farm equipment.
[0003] In the current technology, an Automatic Identification System (AIS) base station is installed to communicate with the ship-borne AIS equipment to obtain the ship's latitude and longitude coordinates, speed and heading, etc., and combined with electronic fences, ships that enter the protection area are monitored, and the fused position information is sent to the optoelectronic equipment to track and photograph the ship. However, for ships that are not equipped with ship-borne AIS equipment or whose ship-borne AIS equipment is turned off, it is impossible to obtain their position information, and ships that threaten the safety of offshore wind power equipment will be missed. When the equipment is damaged or hit by the ship's anchor, the optoelectronic equipment cannot store evidence in time. The active detection method of the detection radar can only obtain the moving speed and longitude and latitude coordinates of the target object, and it is impossible to determine whether it is a ship, because it is impossible to prepare an alarm.

[0032] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.
[0033] The acquisition, storage, use, and processing of data in the technical solution disclosed in this disclosure are in compliance with the relevant provisions of relevant laws and regulations.
[0034] It should be noted that in the embodiments of the present application, certain software, components, models and other existing solutions in the industry may be mentioned, and they should be considered as exemplary. Their purpose is only to illustrate the feasibility of implementing the technical solution of the present application, but it does not mean that the applicant has or will necessarily use the solution.
[0035] Figure 1 is a schematic diagram of a vessel identification method according to an embodiment of the present disclosure, such as Figure 1 As shown, the vessel identification method comprises the following steps:
[0036] S101, obtaining radar data of a ship determination area and a target radar of a target offshore booster station, wherein the target radar is used to scan ships near the target offshore booster station.
[0037] In actual operation, when a ship is close to an offshore booster station, or when it drops anchor near the submarine optical cable connecting the offshore booster station to the land, there is a possibility that the ship will collide with the offshore booster station, or the anchor may hook onto the submarine cable, posing a safety hazard.
[0038] The ship identification method of the embodiment of the present application can be applied to the scenario of an offshore booster station. The executor of the ship identification of the embodiment of the present application can be the ship identification device of the embodiment of the present application, and the ship identification device can be set on an electronic device.
[0039] It should be noted that the offshore booster station is a very important component of an offshore wind farm. It is used to boost the electricity generated by the wind farm from a lower voltage level to a high voltage level suitable for long-distance transmission. This boosting process is crucial for efficiently transmitting electricity to the power grid on land.
[0040] In the disclosed embodiment, the target radar may be arranged in the offshore booster station or around the offshore booster station, without any limitation herein.
[0041] It should be noted that the ship judgment area is usually a certain area around the target object that needs to be judged by the ship, which is designed in advance and can be changed according to actual design needs. No limitation is made here.
[0042] In one possible implementation, an electronic fence can be drawn based on the protection range of the submarine cable and the wind turbine, and the area of the electronic fence can be used as the ship judgment area. Figure 2 As shown, an electronic fence is a virtual boundary used to monitor and control ships or other objects entering a specific area. In offshore wind farms, electronic fences are mainly used to protect offshore optical cables and offshore wind turbines from potential collision risks.
[0043] In actual operation, designers can control the size of the electronic fence to control the accuracy of ship detection. For example, the electronic fence can be set 300 meters to the left and right of the main submarine cable and 300 meters away from the outermost wind turbine of the wind farm. The electronic fence can also be set 500 meters to the left and right of the main submarine cable and 500 meters away from the outermost wind turbine of the wind farm. Obviously, the accuracy of ship detection at the first distance of 300 meters is lower than the accuracy of ship detection at the second distance of 500 meters.
[0044] S102: Determine candidate ships and ship information of the candidate ships based on radar data.
[0045] In the embodiments of the present disclosure, the vessel information may include various types, which are not limited herein. For example, the vessel information may include the shape, length, height, and coordinates of the candidate vessel. In another possible implementation, the moving track, speed, etc. of the candidate vessel may also be analyzed based on continuous radar data.
[0046] S103: Perform a first screening based on the ship information to determine a target candidate ship from the candidate ships.
[0047] Due to possible radar data distortion, or the candidate ship cannot cause safety hazards to the target offshore booster station, etc. Therefore, it is necessary to screen the candidate ships to reduce the amount of data for subsequent data processing, and at the same time narrow the scope of ships and reduce the cost of data processing.
[0048] It should be noted that there may be many methods for the first screening, and no limitation is made here.
[0049] In a possible implementation, a screening condition may be set, and when the screening condition is met, the candidate vessel is considered to be a target candidate vessel. The screening condition is designed in advance and may be changed according to actual design needs, and is not limited here. For example, the screening condition may limit the size, shape, and area of the vessel.
[0050] In another possible implementation manner, the vessel information may be input into a target candidate vessel determination model to determine whether the candidate vessel is a target candidate vessel.
[0051] The target candidate ship determination model is pre-trained and is used to determine whether a candidate ship is a target candidate ship based on ship information. The target candidate ship determination model can be stored in a storage space of an electronic device to facilitate retrieval and use when needed. S104, performing a second screening of the target candidate ships based on the ship judgment area to determine the target ship of the target offshore booster station.
[0052] It should be noted that the second screening is screening based on the ship determination area, and the coordinates of the target candidate ship can be screened based on the ship determination area to determine the target ship.
[0053] Furthermore, in the disclosed embodiment, the latitude and longitude coordinates of the candidate ship can be determined from the cleaned radar identification results, and the latitude and longitude coordinates can be transmitted to the control pan-tilt platform of the long-focal-length video device. After the video device controls the pan-tilt platform based on the latitude and longitude coordinates of the suspicious target, the video angle is adjusted to aim at the possible target, an image of the possible target is captured, and image recognition is performed at the edge to determine whether the candidate ship is indeed a ship, rather than other objects similar to a ship, such as driftwood, large fish, etc.
[0054] In the disclosed embodiment, the ship judgment area of the target offshore booster station and the radar data of the target radar are first obtained, wherein the target radar is used to scan the ships near the target offshore booster station, and then the candidate ships and the ship information of the candidate ships are determined based on the radar data, and then the first screening is performed based on the ship information to determine the target candidate ship from the candidate ships, and finally the target candidate ships are secondly screened based on the ship judgment area to determine the target ship of the target offshore booster station. Thus, the ships scanned by the radar are screened twice by the ship information and the ship judgment area to determine the target ship, which can improve the accuracy of ship determination, make up for the situation where the AIS is not installed or the AIS equipment is damaged, and provide an accurate data basis for subsequent alarm data processing, etc.
[0055] It should be noted that if the image recognition result determines that the suspicious target is not a ship, the radar will delete the record of the suspicious target after the judgment result is transmitted to the radar receiving device; if the image recognition result determines that the suspicious target is a ship, the ship number and the recognition judgment result will be transmitted to the radar receiving device, and the radar will continue to track the target and record its subsequent movement trajectory.
[0056] In the above embodiment, the ship information includes the reflection area and height of the candidate ship, and the first screening is performed based on the ship information to determine the target candidate ship from the candidate ships. Figure 3 Explaining further, the method includes:
[0057] S301, obtaining a reflection area threshold and a height threshold.
[0058] It should be noted that the reflection area threshold is a critical value of the reflection area for determining whether a ship is a target candidate ship, and the height threshold is a critical value of the height for determining whether a ship is a target candidate ship.
[0059] The reflection area threshold and height threshold are designed in advance and can be changed according to actual design needs, and are not limited here. For example, the reflection area threshold can be 1 square meter, 2 square meters, etc., and the height threshold can be 50 meters, 10 meters, etc.
[0060] S302: Determine a target candidate ship from the candidate ships based on the reflection area threshold, the height threshold, the reflection area and the height of the candidate ships.
[0061] In the disclosed embodiment, for any candidate ship, the reflection area of the candidate ship is compared with a reflection area threshold, and the height of the candidate ship is compared with a height threshold. In response to the reflection area of the candidate ship being greater than the reflection area threshold and the height of the candidate ship being less than the height threshold, the candidate ship is determined to be a target candidate ship.
[0062] In response to the reflection area of the candidate ship being less than or equal to the reflection area threshold, and / or the height of the candidate ship being greater than or equal to the height threshold, it is determined that the candidate ship is not a target candidate ship.
[0063] In the embodiment of the present disclosure, the reflection area threshold and the height threshold are first obtained, and then the target candidate vessel is determined from the candidate vessels based on the reflection area threshold, the height threshold, the reflection area and the height of the candidate vessel. Thus, by controlling the reflection area threshold and the height threshold, the screening accuracy, shape or size of the target candidate vessel can be controlled, providing a data basis for the subsequent determination of the target vessel.
[0064] In the above embodiment, the target candidate ships are secondly screened based on the ship judgment area to determine the target ship of the target offshore booster station. Figure 4 Explaining further, the method includes:
[0065] S401, for any target candidate ship, obtaining the coordinates of the target candidate ship.
[0066] S402: In response to the coordinates of the target candidate ship being located within the ship determination area, determining the target candidate ship as the target ship.
[0067] Therefore, by determining that the coordinates of the target candidate ship are located within the ship judgment area, it can be considered that the target candidate ship poses a security threat to the target offshore booster station and there is a risk of collision.
[0068] It should be noted that in another possible implementation, the duration that the coordinates of the target candidate ship are located in the ship judgment area may be obtained, and in response to the duration being greater than a duration threshold, the target candidate ship is determined to be the target ship.
[0069] It should be noted that the duration threshold is designed in advance and is the critical value of the time for determining that the target candidate vessel is the target vessel. The duration threshold can be determined according to actual design requirements.
[0070] Figure 5 is a schematic diagram of a vessel identification method according to an embodiment of the present disclosure, such as Figure 5 As shown, the vessel identification method comprises the following steps:
[0071] S501, collecting radar data of the target offshore booster station.
[0072] S502, processing the radar data by using a ship identification method.
[0073] It should be noted that the ship identification method in the embodiment of the present disclosure is as follows: Figure 1-Figure 3 The method described in the embodiment.
[0074] S503, in response to identifying the target ship, performing image recognition on the target ship to determine whether the target ship is a calibration ship.
[0075] In the embodiments of the present disclosure, there may be a variety of image recognition methods, which are not limited herein. For example, radar data may be processed by an image recognition model or image recognition, or an image acquisition device may be used to acquire an image of a target vessel, and the image may be processed by an image recognition model or image recognition to determine whether the target vessel is a calibration vessel.
[0076] It should be noted that the calibration vessel is a vessel that is set in advance and is a vessel that threatens to collide with the target offshore booster station. For example, the calibration vessel may be a vessel of a certain type, such as a transport ship, a cruise ship, or a vessel that exceeds a set size.
[0077] S504: In response to determining that the target vessel is a calibration vessel, continuously monitoring the calibration vessel.
[0078] In one possible implementation, after determining that the target vessel is a calibration vessel, the calibration vessel is continuously monitored. If the movement speed of the calibration vessel toward the target offshore booster station reaches a threshold, or the distance between the calibration vessel and the target offshore booster station reaches a threshold, an alarm may be issued or emergency avoidance measures may be taken, thereby reducing the probability of accidents and improving the safety of the target offshore booster station.
[0079] In the disclosed embodiment, radar data of the target offshore booster station is first collected, and then the radar data is processed by a ship recognition method. Then, in response to identifying the target ship, image recognition is performed on the target ship to determine whether the target ship is a calibration ship. Finally, in response to determining that the target ship is a calibration ship, the calibration ship is continuously monitored. Figure 1-Figure 3 The method described in the embodiment processes radar data to improve the accuracy of ship identification and compensate for the situation where AIS is not installed or the AIS equipment is damaged, thereby reducing the probability of accidents and improving the safety of the target offshore booster station.
[0080] In another possible implementation, an alarm message may be sent to the calibrated vessel to remind the vessel to avoid anchoring near the vessel's judgment area as much as possible, thereby reducing the risk of damage to the submarine optical cable and the target offshore booster station.

[0088] In the embodiment of the present disclosure, the screening module 630 is further used to: for any candidate ship, compare the reflection area of the candidate ship with the reflection area threshold, and compare the height of the candidate ship with the height threshold; in response to the reflection area of the candidate ship being greater than the reflection area threshold, and the height of the candidate ship being less than the height threshold, determine that the candidate ship is a target candidate ship.
[0089] In the embodiment of the present disclosure, the judgment module 640 is further used to: for any target candidate ship, obtain the coordinates of the target candidate ship; in response to the coordinates of the target candidate ship being within the ship judgment area, determine that the target candidate ship is the target ship.

[0091] Therefore, by screening the ships scanned by the radar twice through ship information and ship judgment area to determine the target ship, the accuracy of ship determination can be improved, which can make up for the situation where AIS is not installed or the AIS equipment is damaged, and at the same time provide an accurate data basis for subsequent alarm data processing.
