Abstract

Technical Field
[0001] The present application relates to the field of geographic data monitoring technology, and in particular to an ocean vortex monitoring method, device, electronic device and storage medium. Background Art
[0002] Ocean vortex refers to a cylindrical fluid rotating in the atmosphere or water current. Ocean vortexes are ubiquitous in the world's oceans and play an important role in the transportation and redistribution of material and energy and global climate change. Ocean vortexes are everywhere. In addition to their large size and limited lifespan, they are also characterized by strong randomness and huge energy. According to estimates by physical oceanographers, the kinetic energy contained in them accounts for more than 90% of the total kinetic energy of the ocean, which is much greater than ocean currents. Traditional vortex monitoring relies on satellite imaging technology to detect from high altitudes (above 3km), and through real-time imaging, the characteristics of ocean vortices are extracted from image information to achieve vortex monitoring. Satellites can only obtain ocean current information on the surface of the ocean. However, ocean vortices are three-dimensional structures and are constantly evolving with the influence of sea-air interactions, topography, etc. Therefore, the ocean vortex information obtained by current technology is not accurate enough.

[0082] Next, the solution of the embodiment of the present application will be introduced and explained in detail with reference to specific application examples.
[0083] 1. Airflow vortex monitoring solution:
[0084] The formation of ocean vortices is mainly affected by the sea surface wind, so the observation of meteorological elements in the vortex sea area is an important part of exploring the evolution of ocean vortices. Regardless of whether it is a cyclonic or anticyclonic ocean vortex, the flow of its water body in space is approximately a closed loop.
[0085] Step 1: Determine the vortex position.
[0086] Firstly, based on the flow field information predicted by HYCOM, the distribution of the target ocean vortex is identified by the flow field geometric characteristics (VG) method. Then, combined with the SWOT (Surface Water and Ocean Topography) altimetry satellite observations, the sea surface fluctuation changes in the vortex identification sea area are inverted. By comparing the vortex information identified by HYCOM with the vortex information inverted by SWOT, if both show that there is a vortex in the area, the flow field information of HYCOM is judged to be valid, and the sea area is judged to be a vortex observation area. If the vortex information judged by the two is inconsistent, the high-frequency ground wave radar observation system is further deployed by unmanned boats to observe the sea surface flow field of the target sea area. Then, based on the high-precision sea surface flow field information obtained by the high-frequency ground wave radar, the flow field geometric characteristics method is used to identify the vortex. If it is identified that there is a vortex, the area is set as the target observation sea area, otherwise, it is a non-target observation sea area.
[0087] Step 2: Deployment of meteorological observation equipment.
[0088] Meteorological observations are conducted by combining satellite remote sensing with drones. First, SWOT satellites are used to extract multi-factor information about target sea areas that have been identified as having vortices, including seabed topography, ocean currents, etc. Then, at the remote control site, N (N>13) small drones (monitoring drones) are loaded into the storage bin of the transport drone in a honeycomb box shape, such as Figure 2 shown.
[0089] The honeycomb boxes for storing small observation drones are arranged in a vertical row of 5, with 1 row forming a box group. The plane space is arranged in a regular 10*10 pattern. Therefore, each transport drone can transport 500 small observation drones. When it is estimated that the total number of small drones required is greater than 500, more transport drones will be dispatched to transport the small drones to the designated location in the same way.
[0090] Based on the ocean current information obtained by SWOT satellite inversion and high-frequency ground wave radar observation, the flow field geometric characteristic method is used to obtain the vortex radius R1 and R2 respectively. In order to ensure that the characteristic information of the vortex is collected to the greatest extent, the larger value is taken as the radius of the vortex to be observed R = Max (R1, R2). Combined with the longitude and latitude of the vortex center with R as the radius obtained from satellite data, the vortex center is taken as the target point, the distance S and the route of the transport drone from the land airport to the vortex center are set, and the flight speed of the unmanned transport aircraft is set to v. The time required to reach the vortex center is T = S / v. Due to the influence of sea-air interaction, the vortex center is constantly moving and changing. Every 30 minutes, the SWOT satellite obtains and extracts the location information of the vortex center and sends it to the transport drone through satellite communication. After receiving the new destination location, the transport drone recalculates and updates the time required to reach the vortex center and adjusts the flight route.
[0091] When the transport drone reaches the sky above the center of the vortex, it will control its altitude at 5,000 meters above sea level and gradually descend. When the altitude drops to 500 meters above sea level, the transport drone will hover. At this time, the number of small drones needed is estimated based on the latest vortex radius R obtained. The specific estimation method is: through the M-shaped drone formation in the air, the number of drones deployed on each concentric circle is a geometric sequence, that is, there is 1 small drone in the center of the vortex, 4 drones are deployed on the closest concentric circle, 8 drones are deployed on the second closest concentric circle, and so on. The geometric sequence of 1-4-8-16-32-64-128 is used to determine the number of small drones needed on the concentric circles. From the inside of the vortex to the outside, small observation drones are deployed on the concentric circles in a geometric sequence. As the radius increases, the concentric circles cover an area that increases. The addition of small observation drones helps to collect more detailed and comprehensive information on the vortex change process. The radius difference between each two adjacent concentric circles is 3,000 meters. Figure 3 shown. Figure 3 Schematic diagram of the layout of a small observation drone cluster ( Figure 3 The green circles in the middle represent drones, which are deployed in a 1:4:8:16 ratio array).
[0092] Except for the vortex center, the number of concentric circles M = R / 3000, M is an integer, and the total number of small drones required is K, then:
[0093]
[0094] Then, according to the estimated number of small drones, the bottom hatch is opened. At this time, the honeycomb box type drone storage box is lowered through the lifting hinge inside the transport drone. When the entire row of boxes is moved outside the bottom hatch, the left side of each box is opened, and the small drone is started and flies out of the box, and hovers at a horizontal distance of 5 meters from the box. Then, through the hinge, the honeycomb box storing the small drone is retracted. At this time, the 5 small drones removed from the first box are moved downward 20 meters as a whole, and then another row of boxes is lowered in turn. By analogy, according to the total number of small drones K required to observe this vortex, when the total number of drones removed from the honeycomb box is equal to K, the new box can be stopped from being lowered.
[0095] Step 3: Collection and organization of meteorological elements.
[0096] Each small drone is equipped with GNSS positioning, temperature, altitude, wind speed, humidity, air pressure and other sensors. Each drone collects meteorological information at its location in real time, and sends the location and meteorological information to the receiving system on land via satellite communication at an interval of 1 minute. After receiving the information data, the receiving system saves and backs up the data in DAT format.
[0097] During the data collection process, the SWOT and ground wave radar monitoring data and the position information of all aerial observation drones are synchronously transmitted to the land control station. The computer of the control station uses the flow field geometric characteristic method to calculate the real-time vortex center position, and calculates the change of the vortex center position and the relative position of each drone in the aerial drone cluster to the center of the cluster. When the moving position of the vortex center exceeds the center position of the last drone cluster positioning by 1 km, the control center sends a command to adjust the position to all aerial drones through satellite communication, and sends the latest vortex center position and the relative position of each drone relative to the center position of the cluster to the corresponding drone in the cluster (see Figure 2 ), after receiving the command, all the drones in the air take the drone in the cluster center as the reference moving point, and all the drones fly and move synchronously. According to the relative position command sent by the control center, the drone in the cluster center moves first, and then the other drones in the cluster follow the same Figure 3 The relative position of the drone relative to the central position is moved so that the center of the drone cluster is still above the center of the vortex after the move, and continues to carry out observations and data collection.
[0098] Step 4: Recovery of meteorological observation equipment.
[0099] When it is determined that the ocean vortex has disappeared, the meteorological observation equipment is recovered. The steps are as follows:
[0100] ① After receiving the command that the ocean vortex has disappeared, the ground control station sends hovering and position feedback commands to all small observation drones through satellite communication. After receiving the position feedback command, all small drones return to their original hovering position and send their own GNSS positioning information to the ground control station via satellite. After receiving the position information of the small drone cluster, the ground control station displays the spatial distribution map of the small drone cluster in the control system and counts the total number of drones based on the feedback information. If the number of drones fed back is the same as the number of drones dispatched, the record is consistent. If the numbers are inconsistent, the number of missing drones is equal to the total number of drones dispatched minus the total number of drones that received feedback, and the number of missing drones is recorded.
[0101] ② Based on the received UAV cluster position information, the ground control station calculates the distance between the 4 small UAVs in the first inner ring and the center of the observation cluster, which are recorded as (S1, S2, S3, S4) respectively, and sorts the distances between the 4 UAVs and the center position in descending order. The maximum and minimum distances are Smax and Smin, and a move-together command is sent to the 4 UAVs in the first inner ring of the observation cluster. After receiving the move-together command, the 4 UAVs in the first inner ring move toward the center at the same speed v, with the 1 small UAV at the core of the observation cluster as the center. The longest and shortest time required for the 4 UAVs to move to the center is Tc = Smax / v, Td = Smin / v.
[0102] ③ When the ground control system sends a movement command to the four drones, the timing starts. After receiving the movement command, the four drones start flying towards the center. The time when the four drones arrive at the center should be between [Td, Tc]. When the time record is equal to (Td-5) minutes, in order to avoid the four drones colliding with the drones at the center, the ground control system sends a hovering command to the four drones. After receiving the hovering command, the four drones hover at the original position through satellite communication, and send their own GNSS positioning and altitude information at this time to the ground control system.
[0103] ④ After receiving the positioning and altitude information of the four UAVs, the ground control system calculates the distance between each small UAV and the center position, which are recorded as (L1, L2, L3, L4), sorts the calculated four distance values in descending order, and numbers the UAVs in order of distance from small to large, which are (W1, W2, W3, W4). In the order of the numbers, the flight target points are set as the center point UAVs and parked at equal intervals of 10 meters. The four UAVs in the first inner ring are hovering at heights of 10 meters, 20 meters, 30 meters, and 40 meters from the center position respectively.
[0104] ⑤ The ground control station sends the calculated flight destination and movement instructions to the nearest UAV. Through satellite communication, the UAV closest to the center point starts to move to the designated point after receiving the movement instruction. When it reaches the designated point, the UAV sends a feedback instruction of being in position to the ground control station. After receiving the instruction of being in position, the ground control station sends the calculated flight destination and movement instructions to the second UAV closest to the center position. The same method is used to move the third and fourth UAVs to the top of the center position. When the fourth UAV flies to the designated position, it sends the information that the vertical positioning of the first inner ring cluster is completed to the ground control system. After receiving the feedback information, the ground control system sends instructions to the second inner ring UAV cluster according to the above steps. Please refer to ②-⑤ for details.
[0105] ⑥ When the last drone cluster in the outermost ring is in position vertically, it sends feedback to the ground control station that all drones are in position and the position and altitude information of the top drone. After receiving the feedback information, the ground control station sends a dispatch instruction, the longitude and latitude of the top drone, and the altitude information to the transport drone. After receiving the instruction, the transport drone takes off from the land parking lot and sets the destination of the transport drone to the same longitude and latitude as the top drone in the vertical direction, and the altitude is 100 meters above the top vertical direction. When the transport drone reaches the specified position and altitude, it sends a feedback message of arrival to the ground control.
[0106] ⑦ After receiving the information that the transport drone has arrived, the ground control station sends instructions to the transport drone to open the hatch and lower the honeycomb storage box. After receiving the instructions, the transport drone opens the hatch at the bottom of the transport drone through satellite communication, lowers the first honeycomb sub-box, and sends the latitude, longitude and altitude information of the first honeycomb sub-box (5) after the lowering is completed to the ground control station.
[0107] ⑧ After the first honeycomb sub-box is lowered, the transport drone sends the positioning information to the ground control station. The ground control station groups the small drones in the hovering vertical space into groups of 5 according to the order from top to bottom. The top 5 in the vertical direction are the first group, corresponding to the first honeycomb sub-box. The ground control station sends the first group of 5 small drones from top to bottom according to the received position information (including longitude, latitude and altitude) of the first honeycomb sub-box (5). After receiving the target information command, the small drones rise and fly to the corresponding honeycomb sub-box according to the command. When the first group of 5 small drones arrive at the corresponding sub-box, they stop flying, stop in the box and send the recovered information to the ground control station.
[0108] ⑨ After receiving the information that the first group of 5 small drones have been parked, the ground control station sends a lowering command to the second honeycomb sub-box through satellite communication, and repeats the steps ⑦-⑧ until all small drones in the vertical direction are parked in the honeycomb sub-box. When the last (bottom) small drone in the vertical direction is parked in the honeycomb sub-box, a message is sent to the ground control that the small drone cluster has been parked. After receiving the message, the ground control station sends a command to the transport drone to fold up the sub-box, close the hatch, and return to the ground airport. After receiving the command, the transport drone folds up all the honeycomb sub-boxes, closes the lowering hatch, sets the ground airport as the destination, and returns. At this point, the observation of the aerial meteorological drone cluster is completed.
[0109] 2. Water vortex monitoring solution:
[0110] Step 1: Get the vortex position.
[0111] Firstly, based on the flow field information predicted by HYCOM, the distribution of the target ocean vortex is identified by the flow field geometric characteristics method. Then, combined with the SWOT (Surface Water and Ocean Topography) altimetry satellite observation, the sea surface fluctuation changes in the vortex identification sea area are inverted. By comparing the vortex information identified by HYCOM with the vortex information inverted by SWOT, if both show that there is a vortex in the area, the flow field information of HYCOM is judged to be valid, and the sea area is judged to be a vortex observation area. If the vortex information judged by the two is inconsistent, the high-frequency ground wave radar observation system is further deployed by unmanned boats to observe the sea surface flow field of the target sea area. Then, based on the high-precision sea surface flow field information obtained by the high-frequency ground wave radar, the flow field geometric characteristics method is used to identify the vortex. If it is identified that there is a vortex, the area is set as the target observation sea area, otherwise, it is a non-target observation sea area.
[0112] Step 2: Ocean unmanned equipment transportation.
[0113] After the target vortex position is determined, the position information of the vortex center is sent to the ground control station via satellite communication. After receiving the position information, the ground control system sends the longitude and latitude information of the vortex center to the mother ship docked near the ground control station via satellite communication. The mother ship is a catamaran carrying N surface unmanned boats and underwater submersibles (N>600). After receiving the vortex positioning information, the mother ship sets the vortex center as the destination, synchronizes with the ground control system to estimate the distance from the mother ship to the vortex center, and sends a command to the mother ship to start heading to the vortex center. After receiving the start command, the mother ship begins to sail towards the vortex center.
[0114] Based on the ocean current information inverted by the SWOT satellite, the flow field geometric characteristic method is used to obtain the radii R1 and R2 of the vortex respectively. In order to ensure that the characteristic information of the vortex is collected to the greatest extent, the larger value is taken as the radius of the vortex to be observed R = Max (R1, R2). Combined with the longitude and latitude of the vortex center with R as the radius obtained from satellite data, the vortex center is taken as the target point. Due to the influence of sea-air interaction, the vortex center is constantly moving and changing. Every 30 minutes, the location information of the vortex center is obtained and extracted through the SWOT satellite, and sent to the transport mother ship through satellite communication. After receiving the new destination location, the transport mother ship recalculates and updates the time required to reach the vortex center and adjusts the navigation route.
[0115] Step 3: Transport marine unmanned equipment fleet.
[0116] When the mother ship reaches the center of the vortex, it sends a message of arrival to the ground control center via satellite communication. After receiving the arrival message of the mother ship, the control system sends an instruction to the mother ship to deploy a cluster of unmanned equipment. After receiving the instruction to deploy the equipment, the mother ship stops in place, opens the bottom hatch of the mother ship, and fills the bottom storage bin with water to make the unmanned boat parked in the bottom storage bin float up. The real-time water level values inside and outside the storage bin are obtained by water level gauges installed in the storage bin and on the outer edge of the mother ship. When the water level in the storage bin is equal to the external sea level, the mother ship sends a message to the ground control center that the unmanned boat is in place. After receiving the in-place information, the control center sends an instruction to the mother ship to dispatch the surface unmanned boat via satellite communication.
[0117] After receiving the order to dispatch the unmanned boats, the mother ship sends an order to the cluster of unmanned boats floating on the water in the storage warehouse through satellite communication, telling them to sail out and stop in the sea 100 meters away from the mother ship. After receiving the order, the surface unmanned boat formation sails out of the storage warehouse one by one and is numbered W1, W2, W3...Wn (n is the total number of unmanned boats) according to the order in which the unmanned boats sail out. The unmanned boats arrive at the stopping position designated by the mother ship.
[0118] Each unmanned boat is equipped with a GNSS positioning system, current meter, temperature and salinity chain, wave meter, water level meter, etc.
[0119] Step 4: Deploy unmanned equipment clusters.
[0120] After the unmanned boat formation leaves the mother ship and arrives at the designated location, each unmanned boat sends information about its location and position to the land control center through satellite communication. After receiving the location and position information, the ground control center sends an order to the mother ship to stop at the center of the vortex and conduct observations. After receiving the order, the mother ship starts the current meter, temperature and salinity recorder, wave meter and other observation equipment on the ship to conduct continuous observations at a fixed point in the center of the vortex. When the mother ship starts the observation, it sends information that the observation has started to the ground control center. After receiving the information, the control center begins to plan the route for the surface unmanned boat formation.
[0121] According to the number of the unmanned boat when it leaves the storage warehouse, the north of the mother ship is set as 0 degrees, and the unmanned boats are deployed in a clockwise direction according to the number of the unmanned boats. The angle between every two unmanned boats and the mother ship (vortex center) is 10°. The maximum radius R of the vortex obtained by SWOT inversion analysis is the boundary of the unmanned boat formation. Therefore, taking the mother ship (vortex center) as the origin of the polar coordinates, the position of the i-th unmanned boat in the polar coordinates is (10°*i, R). After the ground control center calculates the position information of each unmanned boat, the command to sail to the designated position is sent to the corresponding unmanned boat through satellite communication. After receiving the command, the corresponding unmanned boats start to sail to their designated positions at a uniform speed one by one. After each unmanned boat arrives at the designated position, it stops in place and sends the information of being in place to the ground control center through satellite communication.
[0122] After receiving the information that all the surface unmanned boat formations are in place, the ground control center sends a command to the unmanned boat formation to start observation. After receiving the command through satellite communication, the unmanned boat starts the current meter, temperature and salinity recorder, wave meter and other equipment on the unmanned boat, and uses the line between the location and the vortex center (the location of the mother ship) as the observation route. Continuous observation and data collection are carried out back and forth on the corresponding route, and the observation data is transmitted back to the ground control center in real time through satellite communication. Figure 4 , Figure 4 This is an example diagram of the vortex profile observation route of the unmanned boat formation. Figure 4 In the figure, the orange center is the mother ship, the green outer circle is the unmanned boat formation, and the black dots are the unmanned boats deployed in the middle.
[0123] During the data collection process of the unmanned boat formation, the SWOT and ground wave radar monitoring data and the position information of all aerial observation unmanned boats are synchronously transmitted to the land control station. The computer of the control station uses the flow field geometric characteristic method to calculate the real-time vortex center position, and calculates the change of the vortex center position and the relative position of each unmanned boat in the unmanned boat cluster with the center of the cluster. When the moving position of the vortex center exceeds the center position of the mother ship last positioning by 1 km, the control center sends a command to adjust the position to all unmanned boats through satellite communication, and sends the latest vortex center position and the position of each unmanned boat relative to the mother ship to the corresponding unmanned boat in the cluster (see Figure 4 ), after receiving the command, all unmanned boats move synchronously with the mother ship at the center of the cluster as the reference moving point. According to the relative position command sent by the control center, the mother ship at the center of the cluster moves first, and then the cluster unmanned boats follow Figure 4 The relative position of the mother ship relative to the center position is moved so that the center of the unmanned boat cluster is still located at the center of the vortex after the move, and continues to carry out observations and data collection.
[0124] Step 5: Recovery of surface unmanned equipment.
[0125] When it is determined that the ocean vortex has disappeared, the ocean hydrological observation equipment is recovered simultaneously. The specific steps are as follows:
[0126] ① After receiving the command that the ocean vortex has disappeared, the ground control station sends a command to all unmanned boats via satellite communication to stop on the spot and feedback the position, heading, and speed. After receiving the command, all unmanned boats stop sailing on the spot and send their own position, speed, and heading information to the mother ship via satellite communication. After receiving the information about the surface unmanned boat formation, the control station classifies the unmanned boat formation according to whether it is heading toward or away from the mother ship. Class A is the unmanned boat heading toward the mother ship, and Class B is the unmanned boat heading away from the mother ship.
[0127] ② The control station sends a command to the Class A unmanned boat to stay where it is, and sends a command to the Class B unmanned boat to change course so that it heads towards the mother ship.
[0128] ③ After receiving the command from the control station, the A-type mother ship remains stationary, while the B-type unmanned boat turns around so that the head of the unmanned boat faces the mother ship. After the adjustment is completed, all unmanned boats send the adjustment completion information to the control station.
[0129] ④ After receiving the information, the ground control station sends a message to all unmanned boats through satellite communication, asking them to approach the mother ship and stop on a radial line 50 meters away from the mother ship. After receiving the command, the unmanned boats sail toward the mother ship along the radial line they observe, stay at a distance of 50 meters from the mother ship, and send an instruction to the control station that they are in position.
[0130] ⑤ After receiving the command, the control station sends a command to the mother ship to open the storage hatch. After receiving the command, the mother ship opens the hatch and bottom water inlet valve of the storage bin at the rear of the mother ship to allow the water outside the hull to flow into the storage bin. Based on the real-time water level values obtained by the water level gauge outside the hull and the water level gauge inside the storage bin, when the two water level values are equal, the mother ship sends a message to the ground control station that the storage bin is ready.
[0131] ⑥ After receiving the message, the control station first sends an instruction to the W1 unmanned boat to return to the storage warehouse of the mother ship according to the order of dispatching the unmanned boats (W1-W2-…Wi-…Wn). After receiving the instruction, the W1 unmanned boat sails to the storage warehouse of the mother ship, stops at the position inside the cabin, and sends the information that it has arrived in the storage warehouse to the ground control station. After receiving the message, the mother ship sends an instruction to the W2 unmanned boat to return to the storage warehouse of the mother ship. After receiving the instruction, the W2 unmanned boat sails to the storage warehouse of the mother ship, stops at the position inside the cabin, and sends the information that it has arrived in the storage warehouse to the ground control station. In this order, the other unmanned boats enter the storage warehouse one by one.
[0132] ⑦ When the last Wn unmanned boat stops at the position in the cabin, a message is sent to the ground control station that all unmanned boats have returned to the storage compartment of the mother ship. After receiving the message, the control station sends an instruction to close the hatch to the mother ship. After receiving the message, the mother ship closes the storage hatch and sends a message to the control station that the hatch has been closed.
[0133] ⑧After receiving the message that the hatch has been closed, the control station sends the positioning information and return instructions to the mother ship to return to the dock. After receiving the instructions, the mother ship returns to the designated docking point.

[0138] (4) During the transportation of the small observation drone cluster, the transport drone monitors the changes in the vortex center position in real time through the SWOT satellite and sends the location information to the transport drone through satellite communication every 30 minutes.
