Description

Technical Field

[0001] The present application relates to the field of submarine cable monitoring, and in particular to a method and device for monitoring marine resources. Background Art

[0002] my country's offshore wind power industry is in a stage of rapid development. As a key infrastructure connecting the land power grid and offshore wind farms, submarine cables play an important role in remote power supply, high-voltage power transmission, power communication and signal transmission.

[0003] However, with the increase in marine development activities, including marine aquaculture, fishing net laying, and anchor throwing, potential threats to the safety of submarine cables have emerged. These problems have led to frequent mechanical failures of submarine cables. Once the cables are damaged, electricity cannot be effectively transmitted, and wind farms have to reduce their operating capacity, resulting in a significant drop in power generation. In addition, the repair of submarine cables is not only technically complex, but also costly. Therefore, it is necessary to monitor and prevent marine resources such as submarine cables from being damaged.

[0004] Existing monitoring and prevention measures for offshore resources mainly rely on optoelectronic devices to track and record ships that enter protected areas where offshore resources are located, and use very high frequency (VHF) radio equipment to warn and drive these ships away. However, the monitoring range of such optoelectronic equipment is usually limited to 10 to 20 kilometers, which is very limited for wind farms far from the coastline. In addition, the effectiveness of the VHF drive-off method depends on whether the ship is equipped with corresponding radio receiving equipment. For ships without such equipment, this method is completely ineffective. Summary of the invention

[0043] The embodiments of the present application are described in detail below, and examples of the embodiments 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 application, and should not be construed as limiting the present application.

[0044] The following describes a method for monitoring offshore resources according to an embodiment of the present application with reference to the accompanying drawings.

[0045] Figure 1 A flow chart of a method for monitoring offshore resources provided in an embodiment of the present application.

[0046] like Figure 1 As shown, the monitoring method for marine resources is performed by a drone and includes:

[0047] Step 101: receiving expulsion information sent by a control center in real time, wherein the expulsion information includes position information of the ship to be expelled.

[0048] The location information may be the latitude and longitude coordinates of the ship to be expelled.

[0049] In the present application, the control center can generate expulsion information based on the position information of the ship to be expelled in real time, and send the generated expulsion information to the drone. Thus, the drone can obtain the position information of the ship to be expelled.

[0050] In addition, the expulsion information may include the position information of multiple ships to be expelled, or may include the position information of one ship to be expelled.

[0051] Optionally, the control center may also send the identification, call sign, speed, heading, moving speed and other information of the ship to be expelled to the drone, so that the drone can expel the ship to be expelled. The identification of the ship to be expelled may be the ship number or other unique information used to identify the ship, and this application does not limit this.

[0052] Step 102: Navigate to the ship to be expelled based on the position information.

[0053] In the present application, when there is only one ship to be expelled, a navigation route may be generated based on the location information of the ship to be expelled, so as to navigate to the location of the area where the ship to be expelled is located based on the navigation route.

[0054] Optionally, in the case where there are multiple ships to be expelled, the expulsion order of the multiple ships to be expelled is determined based on the distance between the position information of each ship to be expelled and the drone, so as to sail towards the multiple ships to be expelled based on the expulsion order.

[0055] The process of determining the order of expelling multiple ships to be expelled based on the distance between the position information of each ship to be expelled and the drone can be as follows: based on the position information of each ship to be expelled and the position information of the drone, the distance between the ship to be expelled and the drone is determined, and the order of expelling the ships to be expelled is determined according to the order of distance from small to large. In this way, multiple drones can be expelled efficiently.

[0056] Alternatively, the process of determining the order of expelling multiple ships to be expelled based on the distance between the position information of each ship to be expelled and the drone can also be as follows: based on the position information of each ship to be expelled and the position information of the drone, the distance between the ship to be expelled and the drone is determined. Then, the ship to be expelled corresponding to the smallest distance is determined as the first. Then, the ship to be expelled with the smallest distance from the first ship to be expelled among the remaining ships to be expelled whose order of expulsion has not been determined is determined as the second. Then, the ship to be expelled with the smallest distance from the second ship to be expelled among the remaining ships to be expelled whose order of expulsion has not been determined is determined as the third, until the order of expulsion of all ships to be expelled is determined.

[0057] The process of sailing to multiple ships to be expelled based on the expulsion order can be: after the current ship to be expelled leaves the protection zone, sail to the next ship to be expelled of the current ship to be expelled according to the expulsion order. For example, the expulsion order of the ships to be expelled is ship 1, ship 2, and ship 3. The drone sails to ship 1, waits for ship 1 to leave the protection zone, then sails to ship 2, waits for ship 2 to leave the protection zone, and then sails to ship 3. The protection zone is the sea area where the marine resources are located.

[0058] Alternatively, the process of sailing to multiple ships to be expelled based on the expulsion order can also be: sailing to the position of each ship to be expelled in turn according to the expulsion order, and staying at the position of each ship to be expelled for a predetermined time until all ships to be expelled leave the protection zone. For example, the expulsion order of the ships to be expelled is ship 1, ship 2, and ship 3. The drone sails to ship 1, stays for a preset time, and then sails to ship 2. After staying in the area where ship 2 is located for a preset time, it sails to ship 3. After staying in the area where ship 3 is located for a preset time, the above steps are repeated until all ships to be expelled leave the protection zone. In the above-mentioned process, if a ship to be expelled has left the protection zone, the ship to be expelled is removed from the expulsion order and no longer sailed to the position of the ship to be expelled. For example, if ship 2 has left the protection zone, ship 2 is removed from the expulsion order, and then it sails to ship 1 and ship 3 in order.

[0059] Step 103, in response to arriving at the position of the ship to be expelled, shouting to the ship to be expelled through a loudspeaker to drive it away, and taking photos of the ship to be expelled to collect evidence, until the ship to be expelled leaves the protection area.

[0060] In the present application, every time the UAV flies to the position of the ship to be expelled, it can shout to the ship to be expelled through the loudspeaker to drive it away, thus avoiding the phenomenon that the ship cannot receive the expulsion information and cannot be expelled when it is not equipped with radio receiving equipment (very high frequency radio station), thereby improving the reliability of driving away the ship and the reliability of marine resource monitoring.

[0061] In addition, drones can also use the image acquisition equipment on board to take photos and collect evidence of the ships to be expelled, so as to preserve image data of the ships entering the protected area.

[0062] In the present application, when the expulsion information received by the drone at the next moment does not contain the location information of the ship to be expelled, it means that the ship to be expelled has left the protection zone. Therefore, the expulsion mission of the ship to be expelled can be terminated. Alternatively, when the control center detects that the ship to be expelled has left the protection zone, it can send an instruction to terminate the expulsion mission for the ship to be expelled to the drone. After the drone receives the instruction to terminate the expulsion mission for the ship to be expelled, it can terminate the expulsion mission for the ship to be expelled.

[0063] In the present application, the expulsion information sent by the control center is received in real time, wherein the expulsion information includes the location information of the ship to be expelled. The ship to be expelled is driven toward based on the location information. In response to arriving at the location of the ship to be expelled, the ship to be expelled is shouted out through a loudspeaker to be driven away, and the ship to be expelled is photographed and evidence is collected until the ship to be expelled leaves the protected area. Thus, the use of drones to photograph and collect evidence and shout out to drive away the ship to be expelled solves the difficulty of insufficient visual range of optoelectronic equipment and inability to track and photograph distant ships. At the same time, it avoids the phenomenon that ships cannot receive expulsion information and cannot be driven away when no radio receiving equipment is installed. Thereby, the reliability of driving away ships is improved, and then the reliability of marine resource monitoring is improved.

[0064] Figure 2 A flowchart of another method for monitoring offshore resources provided in an embodiment of the present application.

[0065] like Figure 2 As shown, the monitoring method for offshore resources is executed by a control center and includes:

[0066] Step 201, based on AIS and radar technology, monitor the ships in the nearby sea area in real time to obtain the location information of all ships.

[0067] The location information may be the latitude and longitude coordinates of the ship to be expelled.

[0068] When obtaining the ship's location information through AIS monitoring, it is necessary to install AIS equipment on the ship. If the ship is not equipped with AIS equipment, the ship's location information cannot be obtained through AIS monitoring.

[0069] In this application, an AIS base station is installed at the offshore booster station to receive broadcasts from ships in nearby waters to obtain navigation-related dynamic information such as the latitude and longitude coordinates, heading, speed, track direction, and static ship information such as the ship name, identification code, ship type, call sign, etc.

[0070] In addition, a ship detection radar is installed at the offshore booster station, which uses active detection to determine the location information and movement speed of ships in nearby waters by emitting electromagnetic waves and receiving electromagnetic waves reflected by objects at sea.

[0071] Afterwards, the location information of the ships obtained through AIS and radar will be integrated to obtain the location information of all ships, so as to avoid the omission of monitoring of ships entering the protected area, improve the reliability of ship monitoring, and further improve the reliability of marine resource monitoring.

[0072] For example, the first position information of each ship obtained through AIS is compared with the second position information of each ship obtained through radar. When the distance between a certain first position information and a certain second position information is less than a preset threshold, it means that the two position information correspond to the same ship. At this time, any one of the first position information and the second position information can be retained and the other can be deleted. For example, the first position information 1 and the first position information 2 are obtained through AIS, and the second position information 1 and the second position information 2 are obtained through radar. Assuming that only the distance between the first position information 2 and the second position information 1 is less than the preset threshold, the first position information 2 can be retained and the second position information 1 can be deleted. As a result, the position information of all ships obtained is the first position information 1, the first position information 2, and the second position information 2.

[0073] Step 202, all ships are matched with the authorized ship list to determine the ships to be expelled from all ships.

[0074] In this application, an authorized ship list can be pre-set in the system, and the authorized ship list contains the identifiers of the maintenance ships operating in the protected area, where the identifier can be information such as the ship number used to uniquely identify the ship. Afterwards, the identifier of each ship in the nearby sea area obtained through monitoring can be matched with the identifier in the authorized ship list to determine the ship to be expelled from all ships.

[0075] Alternatively, the location information of the maintenance ship operating in the protected area can be obtained in real time, and the location of each ship in the nearby sea area obtained by monitoring is matched with the location information of the maintenance ship. When the distance between the location information of a certain ship and the location information of the maintenance ship is greater than a threshold, the ship is determined as a ship to be expelled. The protected area is the sea area where the marine resources are located.

[0076] Step 203: Send the position information of the ship to be expelled to the drone, so as to instruct the drone to expel the ship to be expelled.

[0077] Optionally, when the ship to be expelled at the previous moment is not included in the ships to be expelled determined at the current moment, it means that the ship to be expelled at the previous moment has left the protection zone. At this time, an instruction to end the expulsion mission for the ship to be expelled at the previous moment can be generated and sent to the drone to instruct the drone to end the expulsion mission.

[0078] In this application, the ships in the nearby sea area are monitored in real time based on AIS and radar technology to obtain the location information of all ships. After that, all ships are matched with the authorized ship list to determine the ships to be expelled among all ships. Then, the location information of the ships to be expelled is sent to the drone to instruct the drone to expel the ships to be expelled. Thus, the ships in the nearby sea area are monitored in real time through AIS and radar technology to avoid omissions in monitoring ships entering the protected area and improve the reliability of ship monitoring. In addition, the drone is used to drive away the ships to be expelled, which avoids the phenomenon that the ships cannot receive the expulsion information and cannot be expelled when the radio receiving equipment is not installed. Thereby, the reliability of driving away the ships is improved, and then the reliability of marine resource monitoring is improved.

[0079] Figure 3 An interactive schematic diagram of another method for monitoring offshore resources provided in an embodiment of the present application.

[0080] like Figure 3 As shown, the monitoring method for offshore resources includes:

[0081] Step 301: The control center monitors the ships in the nearby sea area in real time based on AIS and radar technology to obtain the location information of all ships.

[0082] Step 302: The control center matches all ships with the authorized ship list to determine the ships to be expelled from all ships.

[0083] Step 303: The control center sends the location information of the ship to be expelled to the drone, so as to instruct the drone to expel the ship to be expelled.

[0084] Step 304: The UAV receives the expulsion information sent by the control center in real time, wherein the expulsion information includes the location information of the ship to be expelled.

[0085] Step 305: The drone drives toward the ship to be expelled based on the location information.

[0086] Step 306, the drone responds and arrives at the location of the ship to be expelled, shouts to the ship to be expelled through the loudspeaker to drive it away, and takes photos of the ship to be expelled to collect evidence until the ship to be expelled leaves the protection area.

[0087] In the present application, the specific implementation process of steps 301 to 306 can be found in the detailed description of any embodiment of the present application, and will not be repeated here.

[0088] In order to implement the above embodiment, the embodiment of the present application also proposes a monitoring device for marine resources. Figure 4 A schematic diagram of the structure of a marine resource monitoring device provided in an embodiment of the present application.

[0089] like Figure 4 As shown, the marine resource monitoring device 400 is applied to a drone, and includes:

[0090] The transceiver module 410 is used to receive the expulsion information sent by the control center in real time, wherein the expulsion information includes the location information of the ship to be expelled;

[0091] A driving module 420, used for driving towards the ship to be expelled based on the position information;

[0092] The expulsion module 430 is used to respond to and arrive at the location of the ship to be expelled, shout to the ship to be expelled through a loudspeaker to expel it, and take photos of the ship to be expelled to collect evidence until the ship to be expelled leaves the protection area.

[0093] In a possible implementation of another embodiment of the present application, there are multiple ships to be expelled, and the driving module is used to:

[0094] Determine the order of expelling multiple ships to be expelled based on the position information of each ship to be expelled and the distance between the drone;

[0095] Sailing towards multiple ships to be expelled based on the expulsion order.

[0096] In a possible implementation of another aspect of the present application, the travel module is used to:

[0097] After the current vessel to be expelled leaves the protection zone, the vessel shall then sail to the next vessel to be expelled in the expulsion order; or,

[0098] The ship will sail to the location of each ship to be expelled in turn according to the expulsion order, and stay at the location of each ship to be expelled for a predetermined period of time until all ships to be expelled have left the protection zone.

[0099] It should be noted that the above explanation of the embodiment of the method for monitoring marine resources performed by a drone is also applicable to the embodiment of the monitoring device for marine resources applied to a drone, so it will not be repeated here.

[0100] In the present application, the expulsion information sent by the control center is received in real time, wherein the expulsion information includes the location information of the ship to be expelled. The ship to be expelled is driven toward based on the location information. In response to arriving at the location of the ship to be expelled, the ship to be expelled is shouted out through a loudspeaker to be driven away, and the ship to be expelled is photographed and evidence is collected until the ship to be expelled leaves the protected area. Thus, the use of drones to photograph and collect evidence and shout out to drive away the ship to be expelled solves the difficulty of insufficient visual range of optoelectronic equipment and inability to track and photograph distant ships. At the same time, it avoids the phenomenon that ships cannot receive expulsion information and cannot be driven away when no radio receiving equipment is installed. Thereby, the reliability of driving away ships is improved, and then the reliability of marine resource monitoring is improved.

[0102] The acquisition module 510 is used to monitor the ships in the nearby sea area in real time based on AIS and radar technology to obtain the location information of all ships;

[0103] A determination module 520 is used to match all ships with the authorized ship list to determine the ships to be expelled from all ships;

[0104] The transceiver module 530 is used to send the position information of the ship to be expelled to the drone, so as to instruct the drone to expel the ship to be expelled.

[0105] It should be noted that the above explanation of the embodiment of the offshore resource monitoring method executed by the control center is also applicable to the offshore resource monitoring device applied to the control center in the embodiment, so it will not be repeated here.

[0106] In this application, the ships in the nearby sea area are monitored in real time based on AIS and radar technology to obtain the location information of all ships. After that, all ships are matched with the authorized ship list to determine the ships to be expelled among all ships. Then, the location information of the ships to be expelled is sent to the drone to instruct the drone to expel the ships to be expelled. Thus, the ships in the nearby sea area are monitored in real time through AIS and radar technology to avoid omissions in monitoring ships entering the protected area and improve the reliability of ship monitoring. In addition, the drone is used to drive away the ships to be expelled, which avoids the phenomenon that the ships cannot receive the expulsion information and cannot be expelled when the radio receiving equipment is not installed. Thereby, the reliability of driving away the ships is improved, and then the reliability of marine resource monitoring is improved.
