Description

Technical Field

[0001] The present invention relates to the technical field of fishery, and in particular to a fishing auxiliary device capable of detecting fish schools and a detection system thereof. Background Art

[0002] When fishing in the sea, in order to improve fishing efficiency, reduce operating costs, and accurately grasp the dynamics of fish schools, it is necessary to use fishing auxiliary devices; the detection components of the device can effectively detect the position and size of fish schools in the sea water, and transmit the information to the fishing boat, providing data support for fishing operations and helping to plan fishing strategies; however, traditional fishing auxiliary devices are usually installed on fishing boats. During the detection process, the detection signal is sent out in all directions with the boat as the center, which makes the detection signal easily affected by the noise and water waves generated by the navigation of the boat; at the same time, the detection range is limited by the movement of the boat, and it is impossible to perform synchronous detection of multiple sea areas at the same time, which reduces the efficiency of the device and the coverage of fishing operations.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. This device utilizes a lifting device to separate the detection component from the fishing vessel, preventing interference with the detection signal from noise and waves generated by the vessel's movement. The detection component's main shell, top cover, and bottom plate form a closed main chamber, allowing the sonar components within to operate independently and unaffected by the vessel's movement. During use, the lifting device can deploy the detection components to waters far from the vessel, and multiple components can be deployed simultaneously, breaking through the limitations of traditional ship-centric detection systems. Furthermore, the water inlet and outlet ports on either side of the main shell, combined with the multiple water tanks in the weight-added assembly, can add weight by adding water to the device's chassis, further stabilizing it and preventing external forces such as wave impact and strong wind disturbances from causing the device to sway, shift, or even capsize. Draining water reduces the device's weight, facilitating rapid retrieval of the lifting device. Flexible weight adjustment effectively enhances the device's detection stability and operational adaptability in complex sea conditions. The floating components around the main shell, including support legs, the first airbag, springs and other structures, can provide stable buoyancy for the device, ensuring its stable detection on the sea surface, realizing simultaneous detection of multiple sea areas, and improving the efficiency of the device and the coverage of fishing operations.

[0040] 2. This device utilizes multiple innovative structures to ensure detection accuracy and stability. In the sonar assembly, the mounting plate is connected to the base plate via multiple hydraulic buffers, effectively absorbing external vibrations and reducing their impact on the sonar generator and receiver. A raised plate divides the mounting plate into first and second mounting areas of varying heights, which, combined with the sonar window in the center of the base plate, optimizes the sonar signal transmission and reception paths. Furthermore, a silicone plate positioned between the stop plate and the mounting plate not only isolates external interference, but also maintains clearance contact with the sonar element at the wavy silicone contact point on its bottom, protecting the element while ensuring signal transmission. The heat sink, consisting of a copper tube and a heat sink, is linked to the weighted assembly's water tank and first water pump, utilizing seawater circulation to dissipate heat and ensure the stability of the sonar assembly during extended operation. Furthermore, in the flotation assembly, the support legs are pivotally connected to the main body shell via connecting clips. The first airbag is inflated by the air pump to provide buoyancy. The spring, connecting rod, and connecting sleeve work together to enable the device to adapt to wave conditions, further enhancing its stability and detection accuracy in complex sea conditions.

DETAILED DESCRIPTION

[0060] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but are not intended to limit the scope of protection of the present invention.

[0061] Example:

[0062] like Figures 1 to 17As shown, the present invention provides a fishing assistance device capable of detecting fish schools. It includes a fishing vessel 101 and a detection assembly. The fishing vessel 101 serves as the carrier for the entire fishing operation, performing multiple functions, including transportation and control. The hoisting device 102 mounted on the vessel consists of a sturdy metal frame and a powerful lifting mechanism. The metal frame provides stable support for the lifting operation, while the lifting mechanism can adjust the height and force of the lifting force according to actual needs, ensuring smooth retraction and deployment of the detection assembly and ensuring that the detection assembly can reach the designated sea area for operation. The main body shell 103 of the detection assembly is constructed of high-strength, corrosion-resistant material, offering excellent pressure resistance and the ability to withstand the water pressure and erosion of seawater at deep sea depths. The main body shell 103 is equipped with a top cover 104 and a bottom plate 105 at the top and bottom, respectively. The top cover 104 is well-sealed, effectively preventing seawater from seeping into the main body cavity and protecting the internal equipment. The thicker bottom plate 105 provides a stable support base for the internal components. The three components are interconnected to form a closed main body cavity, providing a safe working environment for the sonar assembly and weight-added assembly. At the same time, the water inlet 106 and the drain outlet 107 provided on both sides of the main shell 103 are of moderate size and are used in conjunction with the weight-increasing components. The water inlet 106 can quickly introduce seawater, increasing the weight of the device; the drain outlet 107 has a high drainage efficiency and can discharge seawater in a timely manner, reducing the weight of the device. A plurality of baffles 302 are provided on the bottom plate 105. These baffles 302 are vertically fixed on the bottom plate 105, and the bottom plate 105 is clearly divided into a detection area and a weight-increasing area by the plurality of baffles 302. The detection area is used to house the sonar components to ensure that they can perform detection work without interference; the weight-increasing area accommodates the weight-increasing components to ensure the stability of the device under different sea conditions.

[0063] The sonar assembly includes multiple sets of sonar generators 201 and multiple sets of sonar receivers 202. The sonar generators 201 can emit sound waves of different frequencies. These sound waves propagate through the seawater and are reflected back after encountering targets such as schools of fish. The sonar receivers 202 can sensitively capture the reflected sound waves and transmit the signals to the subsequent processing system. The mounting plate 203 is connected to the base plate 105 via multiple sets of hydraulic buffers 204. The hydraulic buffers 204 can effectively absorb vibrations transmitted from the outside world, reducing the impact of vibrations on the sonar generators 201 and sonar receivers 202. The sonar generators 201 and sonar receivers 202 are both mounted on the mounting plate 203, which provides a stable mounting platform for both. The sonar generator 201 can use the RE I-Sonar6000 sonar generator, while the sonar receiver 202 can use the Furuno DFF3D sonar receiver.

[0064] Mounting plate 203 houses controller 205, which integrates multiple circuits and chips, providing powerful data processing capabilities. Both the sonar generator 201 and the sonar receiver 202 are electrically connected to controller 205 via circuits. Controller 205 issues commands to the sonar generator 201, controlling its operation, and receives and analyzes signals from the sonar receiver 202.

[0065] Multiple flotation components are installed around the main shell 103, including support legs 401, a first airbag 402, and other structures. The support legs 401 are made of sturdy material and are rotatably connected to the connecting blocks 403 on the side of the main shell 103, allowing for adjustable angles. The first airbag 402 is installed in mounting boxes 404 on either side of the support legs 401. An air pump inflates the first airbag 402 through an inflation tube, causing it to expand and generate buoyancy. Multiple batteries are installed within the top cover 104. These batteries provide a stable power supply for the entire detection assembly, ensuring the normal operation of all components. They continuously power the sonar generator 201, sonar receiver 202, controller 205, and other equipment, maintaining stable operation of the detection assembly. Alternatively, solar panels can be installed on the device to collect solar energy and convert it into electricity. During daytime hours when there is sufficient sunlight, the solar panels store the generated electricity in the batteries, supplementing the power supply and reducing reliance on traditional electricity. This allows the detection assembly to operate longer at sea and improves its overall endurance.

[0066] like Figure 4 、 Figure 11 、 Figure 12 、 Figure 15 As shown, mounting plate 203 is provided with a boss 206. Boss 206 protrudes upward from the surface of mounting plate 203 at a moderate height, naturally dividing mounting plate 203 into two areas. Boss 206 divides mounting plate 203 into a first mounting area and a second mounting area. The first mounting area is surrounded by the second mounting area. This layout clearly demarcates the two areas and provides clear space for installing different components. The sonar generator 201 is installed in the first mounting area, which is appropriately sized to accommodate the sonar generator 201. The sonar receiver 202 is installed in the second mounting area, which is also designed to fit the sonar receiver 202's dimensions, ensuring it is not easily shaken after installation.

[0067] The mounting plate 203 forms a stepped structure with the aid of the boss 206, with the first mounting area being higher than the second mounting area. This height difference arrangement allows the sonar generator 201 and the sonar receiver 202 to be spatially staggered. This distribution avoids potential interference between the two during operation, while also providing more reasonable spatial conditions for the transmission and reception of sound waves. A sonar window 207 is provided in the center of the base plate 105. The sonar window 207 is a transparent area made of a material that allows sound waves to pass smoothly. Both the sonar generator 201 and the sonar receiver 202 are located directly above the sonar window 207, allowing the sound waves emitted by the sonar generator 201 to be directly transmitted into the seawater through the sonar window 207, while the reflected sound waves can also be received by the sonar receiver 202 through the sonar window 207, reducing obstructions to the sound waves during transmission.

[0068] A limit frame 208 is positioned above the base plate 105. The limit frame 208 is composed of multiple brackets whose height and shape match the mounting plate 203. The mounting plate 203 is positioned between the limit frame 208 and the base plate 105. The limit frame 208 limits the range of movement of the mounting plate 203, preventing it from significantly shifting during operation. A silicone plate 209 is positioned between the limit frame 208 and the mounting plate 203. The silicone plate 209 is soft and has a certain degree of elasticity. The silicone plate 209 covers the mounting plate 203, encasing both the sonar generator 201 and the sonar receiver 202. A gap is formed between the silicone plate 209 and the sonar generator 201, sonar receiver 202, and the silicone plate 209. This gap ensures that the sonar generator 201 and sonar receiver 202 are not excessively squeezed by the silicone plate 209, while also providing some protection from potential external shocks and minor vibrations.

[0069] A plurality of groups of silicone contact points 210 are arranged at the bottom of the silicone plate 209. These silicone contact points 210 are in the shape of waves. Each silicone contact point 210 has a certain degree of flexibility, and one end thereof is respectively against the sonar generator 201 and the sonar receiver 202. When the device is shaken by the wind and waves on the sea surface, the wavy silicone contact points 210 can cushion the vibrations transmitted from the outside to the sonar generator 201 and the sonar receiver 202 through their own deformation, while not hindering the normal operation of the sonar equipment, thereby ensuring the stable operation of the sonar component in complex environments. The limit frame 208 is equipped with a heat sink, which consists of a heat sink copper tube 211 and a plurality of heat sink plates 212. The heat sink copper tube 211 is placed between the two groups of heat sink plates 212 and is in direct contact with the heat sink plates 212, thereby forming a sandwich structure. The heat dissipation copper tube 211 has good thermal conductivity and can quickly absorb heat, while the heat dissipation plate 212 further expands the heat dissipation area, helping heat to be dissipated to the surrounding environment more quickly.

[0070] The silicone plate 209 is provided with multiple sets of heat dissipation holes, which penetrate the upper and lower surfaces of the silicone plate 209. The top of the silicone plate 209 is fitted with one set of heat dissipation plates 212. With the help of the heat dissipation holes, the heat generated by the sonar assembly can be smoothly transferred to the heat dissipation plates 212. At the top of the other set of heat dissipation plates 212, there are multiple sets of heat dissipation fins 213. These heat dissipation fins 213 extend outward, further increasing the contact area with the air and accelerating the heat dissipation rate, ensuring that the performance of the sonar assembly will not be affected by overheating during long-term operation. The heat dissipation copper tube 211 has a water inlet 214 at one end and a water outlet 215 at the other end. The water inlet 214 is connected to the weight-added assembly through a connecting tube, and the first water pump equipped in the main body cavity can drive the water circulation. When the device is operating, the first water pump draws seawater from the weighted assembly through water inlet 214 into the heat dissipation copper tube 211. The seawater flows through the copper tube, absorbing heat from the heat dissipation copper tube 211 and the heat sink 212. The heated seawater then flows through water outlet 215 and, through a connecting pipe, is discharged from the device through drain port 107. This circulation of seawater ensures continuous heat dissipation of the sonar assembly, ensuring stable operation and allowing the entire detection assembly to maintain optimal operating conditions even during extended periods of seawater operation.

[0071] like Figure 3 、 Figure 4 、 Figure 16 、 Figure 17 As shown, the weight-increasing assembly includes multiple sets of water tanks 301, which are key components for achieving weight adjustment. These tanks 301 are capable of withstanding the pressure and corrosion of seawater. Along one side of the baffle 302 are multiple sets of limit plates 303, which are vertically fixed to the baffle 302 and together with the baffle 302 form regular fixed areas. The water tanks 301 are embedded in these fixed areas, and the limit plates 303 provide both restraint and support for the water tanks 301, preventing them from moving during operation and ensuring their stable placement.

[0072] Both ends of the water tanks 301 are provided with connecting ports 304, located near the bottom of the water tanks 301. These connecting ports 304 connect two adjacent groups of water tanks 301, forming a continuous, integrated whole. A second water pump, housed within the main body cavity, is connected to one of the water tanks 301 and the water inlet 106 via a connecting pipe. When the weight of the device needs to be increased, the second water pump is activated, introducing seawater from the water inlet 106 into the water tanks 301. The seawater then flows between the connected water tanks 301, evenly filling each tank 301. When the weight needs to be reduced, the second water pump can drain the seawater from the water tanks 301.

[0073] A protrusion 305 is provided on the top of the water tank 301. The interior of the protrusion 305 is hollow and communicates with the interior of the water tank 301. The connection ports 306 on both sides of the protrusion 305 provide channels for further connection between the water tanks 301. The connection port 306 on the protrusion 305 is connected to the connection port 306 on the adjacent protrusion 305 through a connecting pipe 307, so that a connecting structure is also formed on the top of the water tank 301; the setting of the protrusion 305 gives the water tank 301 additional capacity, which can further ensure the filling of seawater in the water tank 301. The multiple groups of fixed blocks 308 on the top of the water tank 301 can clamp the connecting pipe 307 to prevent the connecting pipe 307 from loosening or falling off during the operation of the device, thereby ensuring the reliability of the connection between the water tanks 301. One group of water tanks 301 is connected to the detection assembly, becoming a link for the entire weight-increasing assembly and the detection assembly to work together.

[0074] A laser sensor 309 is mounted on one set of protrusions 305. The laser beam emitted by this sensor penetrates the interior of the water tank 301. The propagation of the laser beam within the water tank 301 allows the water level inside to be monitored. If the water level becomes abnormal, the laser sensor 309 transmits a signal. Laser sensor 309 can be a Keyence LK-G152 laser sensor. A detection tube 310, mounted on one set of connecting pipes 307, is connected to the connecting pipe 307 at one end and a pressure sensor 311 is mounted on the other end. This pressure sensor 311 senses changes in the seawater pressure within the connecting pipe 307 in real time. The top of the detection tube 310 is higher than the water tank 301. This height ensures that when the water tank 301 is filled with seawater, excess seawater flows through the connecting pipe 307 into the detection tube 310. At this point, the pressure sensor 311 comes into contact with the seawater and senses its pressure. When the pressure reaches a preset threshold, pressure sensor 311 sends a signal to controller 205. Upon receiving the signal, controller 205 immediately stops the second water pump to prevent overfilling of water tank 301. Pressure sensor 311 can be a Honeywell ST3000G1A pressure sensor. Both laser sensor 309 and pressure sensor 311 are electrically connected to controller 205 via wiring. They transmit monitored water level and pressure data to controller 205 in a timely manner. Based on this data, controller 205 controls the operating status of the second water pump and adjusts the water volume in water tank 301, effectively controlling the weight of the device and ensuring stable operation in varying sea conditions, meeting the requirements of detection operations.

[0075] like Figure 3 、 Figure 5 、 Figure 6 、 Figure 9As shown, the flotation assembly includes support legs 401 and multiple sets of first airbags 402, which are crucial for ensuring the detector assembly's stable floating on the sea surface. Multiple sets of connecting blocks 403 are evenly distributed around the main shell 103. These connecting blocks 403 are made of a strong metal material and securely welded to the shell 103. The support legs 401 are pivotally connected to the connecting blocks 403 via a rotating shaft, allowing them to rotate freely within a certain angle range, making it easy to adjust their position according to actual usage needs. A rectangular mounting box 404 is located on each side of the support legs 401, with an interior space suitable for accommodating the first airbags 402. The first airbags 402 are made of a flexible and durable rubber material and are installed within the mounting box 404. Multiple air pumps within the main body cavity are connected to the first airbags 402 via inflation tubes. When activated, the air pumps inject air into the first airbags 402, causing them to inflate and generate buoyancy.

[0076] A connecting plate 405 is provided below the installation box 404. This plate-like structure is parallel to the installation box 404. Connecting sleeves 406 are mounted at each end of the installation box 404. Connecting sleeves 406 are cylindrical and hollow. Multiple sets of connecting rods 407 are mounted on the connecting plate 405 at positions corresponding to the connecting sleeves 406. One end of each connecting rod 407 is inserted into and can slide within the connecting sleeve 406. A spring 408 is also mounted within the connecting sleeve 406. One end of the spring 408 is fixed to the inner wall of the connecting sleeve 406, and the other end is connected to the connecting rod 407. When the first airbag 402 is inflated, the expansion of the first airbag 402 will exert force on the connecting plate 405, and the distance between the connecting plate 405 and the installation box 404 will increase; when the first airbag 402 is deflated, the first airbag 402 contracts, and due to the rebound effect of the spring 408, the distance between the connecting plate 405 and the installation box 404 is reduced, so that the first airbag 402 can be stored in the installation box 404.

[0077] The mounting bracket 409 provided in the main body cavity is in a cross structure. The mounting bracket 409 strengthens the support inside the main body shell 103, further ensuring the stability of the main body shell 103. The mounting bracket 409 is inserted into the card slot 419 in the main body shell 103 and then fixed with bolts, thereby enhancing the overall structural strength and resisting the impact of seawater. Multiple sets of dual-axis motors 410 are installed on the mounting bracket 409. A winch 411 is respectively installed at the shaft ends of the dual-axis motor 410. The winch 411 is disc-shaped and has a groove on the surface for winding a steel cable 412. A first connecting block 413 and a second connecting block 416 are welded to the support leg 401. Multiple sets of first pulleys 414 and third pulleys 417 are installed in the main body shell 103, and a second pulley 415 is provided on the connecting block 403. The steel cables 412 wound around one set of winches 411 are first threaded between two sets of first pulleys 414, changing their pulling direction. They are then wound around a second pulley 415, with one end fixedly connected to a first connecting block 413. The steel cables 412 on the other set of winches 411 are wound around a third pulley 417, then threaded through a connecting sleeve 406 on the side of the main body shell 103, with one end connected to a second connecting block 416. When the dual-axis motor 410 rotates, it drives the winches 411, thereby retracting and extending the steel cables 412. The coordination of the steel cables 412, the pulleys, and the connecting block allows the support legs 401 to be deployed and retracted. When the device needs to be used, the support legs 401 are unfolded, and the air pump inflates the first airbag 402 to expand it, and the buoyancy is used to hold the device firmly on the sea surface; when the device needs to be stored, the dual-axis motor 410 rotates in the opposite direction, the winch 411 retracts the steel cable 412, and pulls the support legs 401 toward the main shell 103, and the first airbag 402 is deflated to reduce the occupied space, making it easier for the lifting device 102 to recover the detection component.

[0078] The float assembly also includes a buoy 418, a block-shaped structure located between the main body 103 and the support legs 401. It is mounted on a steel cable 412 on one of the winches 411. One end of the buoy 418 is located within the connecting sleeve 406, and the other end is fixedly connected to the steel cable 412. Pulled by the steel cable 412, the buoy 418 can move along the steel cable 412. The main body 103 includes multiple slots 419, whose shape and size match the mounting bracket 409. Once the mounting bracket 409 is secured within the slots 419, it is removably connected to the main body 103 via multiple bolts. This facilitates installation and removal of the mounting bracket 409 and ensures its stability within the main body 103. This ensures reliable operation of components such as the dual-axis motor 410 and winch 411, ensuring the overall functionality of the float assembly and allowing the detection assembly to float stably on the sea surface and adapt to varying sea conditions.

[0079] like Figure 3 、 Figures 7 to 9 、 Figure 14As shown, a detection system of a fishing auxiliary device capable of detecting a school of fish comprises:

[0080] The detection data module is used to process the information obtained by the controller and external information. The data module is installed in the top cover 104 of the above-mentioned fishing auxiliary device that can detect fish schools. It can receive information from the sonar component, laser sensor 309, pressure sensor 311, etc., and can also obtain external information.

[0081] Specifically, an assembly plate 502 is located beneath the top cover 104. This assembly plate 502 is detachably connected to the top cover 104 via bolts and other components, forming an assembly cavity. The detection data module is mounted on this assembly plate 502 and protected within the cavity, shielding it from external environmental interference. External information, primarily from the ground and shipborne data modules, is used to manage the device's settings.

[0082] Meanwhile, a protective frame 503 is fixed to the top cover 104. The protective frame 503 is composed of a metal frame and houses a wireless communication antenna 504. The wireless communication antenna 504 is connected to the controller 205 and can detect and send information processed by the data module. It also receives external commands and feeds them back to the controller 205, enabling information exchange between the device and the outside world. A wind speed sensor 501 is installed in the assembly cavity. A mounting platform 505 is provided on the top of the top cover 104. A detection sleeve 506 is located on the top of the mounting platform 505 to accommodate the wind speed sensor 501. The wind speed sensor 501 is also mounted on the mounting platform 505 to monitor the external wind speed in real time. The wind speed sensor 501 can use a TW-FS three-cup wind speed and direction sensor. The wind speed sensor 501 can effectively sense real-time changes in the external wind speed, providing important data reference for the stable operation of the fishing detection component. The mounting platform 505 itself is hollow in shape, with multiple sets of sealing plates 507 installed on both sides. When the sealing plates 507 are connected to the mounting platform 505, a sealed cavity is formed, in which the second airbag 508 is placed. The inflation port provided on one set of the sealing plates 507 is respectively connected to the second airbag 508 and the air pump in the main cavity. When the air pump starts working, gas will enter the second airbag 508 through the inflation port, causing it to gradually expand. The second airbag 508 is installed in the sealed cavity of the mounting platform 505. After it expands, it can increase the overall drainage volume of the detection assembly. According to the Archimedes principle, the action of the second airbag 508 gives the entire detection assembly additional buoyancy, further ensuring the floating stability of the detection assembly on the sea surface and reducing the shaking caused by factors such as wind and waves.

[0083] Furthermore, a temperature sensor is mounted on the water inlet 106 to monitor the temperature of seawater entering the water tank 301 within the device. The temperature sensor is also electrically connected to the controller 205 via circuitry, effectively detecting the seawater's temperature. Different fish species have varying preferences for water temperature, and by analyzing water temperature distribution, it's possible to predict likely fish gathering areas. For example, some fish prefer to feed and inhabit areas with suitable water temperatures.

[0084] The ground data module is responsible for processing and displaying the information acquired by the detection data module. This module receives various data from the detection data module, including information about fish schools detected by the sonar component and wind speed data monitored by the wind speed sensor 501. The ground data module organizes and analyzes this information, presenting it on the display screen in an intuitive and easy-to-understand format for easy viewing by the operator. It also provides configuration and management capabilities for the detection component. Through the ground data module, the operator can adjust various parameters of the detection component, such as setting the transmission frequency of the sonar generator 201 and adjusting the water level in the weighted component's water tank 301, enabling the detection component to better adapt to different detection environments and mission requirements.

[0085] The shipboard data module is primarily used to receive and display information processed by the ground-based data module. It connects to the ground-based data module via a specific communication method, acquiring data compiled and analyzed by the ground-based data module. This data is displayed on the shipboard data module's display, allowing onboard personnel to understand the operating status of the detection components and related environmental information in real time. Furthermore, the shipboard data module also allows for configuration and management of the detection components. During actual operation, onboard personnel can use the shipboard data module to adjust detection component parameters based on actual conditions. For example, they can adjust the angle of the floating component's support legs 401 according to the ship's direction and speed to ensure stable operation of the detection components.

[0086] Specifically, the shipboard data module displays basic information about all of the ship's detection components, including their message information. It also manages real-time information about the detection components. Sensors within the detection components, such as the sonar generator 201, sonar receiver 202, laser sensor 309, and wind speed sensor 501, collect various operational data, including sonar-detected fish distribution, water tank 301 water level data, and external wind speed. This real-time information is aggregated by the controller 205 and then transmitted to the corresponding data processing module for intuitive display, allowing operators to easily understand the operating status of the detection components.

[0087] Provides warning management for the detection component. When an abnormality occurs in the detection component, such as malfunctioning sonar components, excessive water in the water tank 301, or abnormal pressure in the float component, the relevant sensor transmits a signal to the controller 205. Controller 205 determines the situation based on preset rules. Once a warning condition is triggered, it issues a warning message via a connected display device or communication module, alerting the operator to take timely action and ensuring safe and stable operation of the device.

[0088] The detection component can be instructed. Operators input control commands based on actual needs on the user interface of the ground data module or the shipboard data module. These commands are transmitted to the detection component's controller 205 via the satellite module or other communication channels. For example, these commands can adjust the sonar component's operating frequency, control the on / off of the weight-added component's second water pump, and thereby control the filling and draining of the water tank 301, thereby adjusting the detection component's operating status.

[0089] The detection component's controller 205 is also capable of receiving commands. It is always ready to receive commands from the ground-based data module or the shipboard data module. Upon receiving a command, the controller 205 interprets the command content and controls the corresponding components accordingly. For example, if a command is received to adjust the angle of the floating component's support legs 401, the controller 205 controls the dual-axis motor 410, driving the winch 411 to retract and release the steel cable 412, thereby adjusting the angle of the support legs 401.

[0090] Logging of the detection component. During the operation of the detection component, the controller 205 records key operations and events, such as the start and stop time of each sonar component, the filling and draining operation records of the water tank 301, and various warning messages. This log information is stored in the device's internal storage device for subsequent query and analysis, helping to understand the device's operating history, troubleshoot, and optimize workflows.

[0091] The shipboard data module can also share detection components, nautical charts, system settings, and basic information. Basic information mainly displays the ship's name, course and speed, longitude and latitude, as well as the detection component's serial number, longitude and latitude, and battery level. It can also send detection component commands, including: immediate position reporting, LED settings, position information return cycle settings, detection component immediate detection, detection component depth measurement settings, detection component sunrise and sunset detection settings, detection component on / off / deletion settings, detection component daily detection frequency settings, and detection component mode settings.

[0092] The satellite module is a key link in the information transmission between the detection data module, the ground data module, and the shipboard data module. Using satellite communication technology, it transmits information collected by the detection data module to the ground data module, enabling the ground terminal to obtain timely operating data from the detection components. Simultaneously, it transmits instructions and information processed by the ground data module to the shipboard data module, enabling remote control of the shipboard detection components. Furthermore, the satellite module transmits feedback information generated by the shipboard data module back to the ground data module, ensuring two-way data flow and smooth information exchange between modules, enabling the coordinated operation of the entire detection system.

[0093] The satellite broadband module transmits information from the ground data module. Leveraging the high bandwidth of satellite broadband communications, it quickly and efficiently transmits large amounts of data from the ground data module. This data includes detailed analysis results of detection data and instructions for configuring and managing detection components. Through the satellite broadband module, the ground data module can quickly deliver information to where it's needed. Whether it's transmitting to other remote terminals or interacting with other systems, it ensures timely and stable data transmission, providing strong support for the efficient operation of the entire detection system.

[0094] It should be noted that in order to simplify the description of the present invention and thus help understand one or more embodiments of the invention, in the foregoing description of the embodiments of the present invention, multiple features are sometimes combined into one embodiment, figure or description thereof.
