Description

Technical Field

[0001] This invention relates to the field of marine survey data acquisition, and in particular to a method, system, terminal equipment, and medium for secure acquisition of marine survey data. Background Technology

[0002] The deep-sea environment contains a wealth of important and researchable deep-sea data, making long-term, covert, and stable measurements of deep-sea areas an urgent need.

[0003] Currently, deep-sea data acquisition primarily relies on submersibles, seabed observation networks, or seabed-based measurement nodes. However, these devices face severe challenges in the complex deep-sea environment. First, in terms of acoustic countermeasures, existing technologies typically employ passive sound absorption or shape concealment to evade detection, but their stealth effectiveness is limited, especially when facing the full-band, multi-angle detection of active sonar, easily revealing their position. Second, in dealing with the complex deep-sea environment, existing measurement devices generally lack intelligent shock-resistant mechanisms. Traditional buffer designs often employ fixed mechanical structures or passive damping materials. When encountering extreme conditions such as the impact of undersea currents, object collisions, or explosive shock waves, the measurement equipment is prone to overload, leading to inaccurate internal precision sensors, structural damage, etc., resulting in measurement mission interruption, data loss, or a significant decrease in acquisition accuracy. Furthermore, existing technical solutions typically treat stealth, shock resistance, and data acquisition as independent functional modules, lacking integrated and coordinated control. This design results in a slow response and low efficiency when the system faces complex scenarios with multiple intertwined environmental threats, making it difficult to ensure the safe, continuous, and reliable acquisition of marine measurement data while completing highly concealed and survivable tasks. Summary of the Invention

[0004] This invention provides a method, system, terminal equipment, and medium for securely acquiring marine measurement data, aiming to solve the aforementioned technical problems and improve the security and reliability of acquiring marine measurement data.

[0005] This invention provides a method for securely acquiring marine measurement data, applied to a deep-sea measurement capsule, the method comprising: Obtain marine information of the sea area to be measured; The offensive sonar signal is extracted from the sea area information, and the anti-phase sonar signal corresponding to the offensive sonar signal is released. Extract shock wave information from the aforementioned sea area information; Based on the preset shock buffer algorithm and the shock wave information, capsule adjustment information is obtained. Based on the capsule adjustment information, the capsule structure is adjusted to obtain the adjusted deep-sea measurement capsule. The offensive sonar signal is canceled by the anti-phase sonar signal, and marine measurement data of the sea area to be measured is obtained based on the adjusted deep-sea measurement capsule.

[0006] In the aforementioned scheme, a corresponding anti-phase sonar signal is generated based on the aggressive sonar signal, thereby effectively canceling the aggressive sonar signal at the physical level. This makes the deep-sea measurement capsule acoustically invisible, effectively improving its concealment and survivability in the measured sea area and providing a safe environment for the deep-sea measurement capsule to measure marine measurement data. Simultaneously, the deep-sea measurement capsule's structure is adjusted based on shock wave information, ensuring that the capsule can reduce the impact of shock waves during measurement and maintain a stable and reliable marine measurement state. The synergistic effect of these two methods solves the problems of easy interruption, exposure, and impact-induced data failure in traditional marine measurement technologies, improving the safety and reliability of marine measurement data acquisition.

[0007] Furthermore, obtaining the sea area information of the sea area to be measured includes: Obtain capsule pressure sensing information from the deep-sea measurement capsule; Based on the pressure sensing information of the capsule, the target seabed is determined and nanofluid is released to construct a solidification layer between the deep-sea measurement capsule and the target seabed. The deep-sea measurement capsule is then fixed to the target seabed based on the solidification layer, thereby obtaining the sea area information.

[0008] In the above scheme, the release of nanofluid is triggered and controlled by the pressure sensing information of the capsule, which then reacts with the seabed to form a solidified layer. This enables the deep-sea measurement capsule to be anchored quickly, stably and reliably on complex seabed geology, overcoming the shortcomings of traditional gravity anchors which are prone to displacement and drilling anchors which have high energy consumption, and ensuring the continuity and accuracy of marine information acquisition.

[0009] Further, the step of determining the target seabed based on the capsule pressure sensing information and releasing nanofluid to construct a solidification layer between the deep-sea measurement capsule and the target seabed based on the nanofluid, thereby fixing the deep-sea measurement capsule to the target seabed based on the solidification layer, and thus obtaining the sea area information, includes: Based on the capsule pressure sensing information, the initial nanoflow rate of the nanofluid and the initial seabed information, current seabed information, initial porosity and current porosity of the target seabed are obtained; Based on the initial seabed information, current seabed information, initial porosity, and current porosity, determine the current nanoflow rate; The nanofluid is released based on the current nanoflow rate until the solidified layer is constructed.

[0010] In the above scheme, by acquiring initial seabed information, current seabed information, initial porosity and current porosity in real time, the current nanofluid flow rate is dynamically determined and adjusted. This effectively optimizes the release curve of the nanofluid according to different seabed geological conditions (such as soft mud, gravel or hard rock), ensuring that a high-strength and uniform solidification layer can be formed on any complex seabed, greatly improving the environmental adaptability and versatility of the deep-sea measurement capsule.

[0011] Further, the step of determining the target seabed based on the capsule pressure sensing information and releasing nanofluid to construct a solidification layer between the deep-sea measurement capsule and the target seabed based on the nanofluid, thereby fixing the deep-sea measurement capsule to the target seabed based on the solidification layer, and thus obtaining the sea area information, includes: Obtain the curing information of the cured layer; The degree of curing of the cured layer is determined based on the curing information; When the curing degree is complete, the gap between the cured layer and the target seabed is suctioned until the negative pressure value between the cured layer and the target seabed is within a preset negative pressure range, and then the sea area information is obtained.

[0012] In the above scheme, by monitoring the degree of solidification and determining that solidification is complete, suction is initiated to create negative pressure in the gap between the solidified layer and the seabed. This allows the two anchoring mechanisms, thixotropic solidification and vacuum adsorption, to produce a synergistic effect, improving the reliability and stability of the deep-sea measurement capsule anchoring.

[0013] Further, the step of extracting offensive sonar signals from the sea area information and releasing anti-phase sonar signals corresponding to the offensive sonar signals includes: The characteristics of the offensive sonar are determined based on the offensive sonar signal. Based on the preset acoustic superposition algorithm and the characteristics of the offensive acoustic sonar, a reverse signal parameter set is obtained; The anti-phase sonar signal is obtained based on the preset anti-phase signal generation algorithm and the inverse signal parameter set.

[0014] In the above scheme, by extracting the characteristics of aggressive sonar from the aggressive sonar signal and generating a reverse signal parameter set based on the sonar superposition algorithm, the anti-phase sonar signal is finally synthesized and emitted, thereby realizing real-time and accurate destructive interference of the aggressive sonar signal, thus providing active acoustic stealth capability for the deep-sea measurement capsule.

[0015] Further, the deep-sea measurement capsule includes an outer shell, a spring support device, and a hydraulic buffer device. The inner wall of the outer shell is connected to one end of the spring support device; the other end of the spring support device is connected to the hydraulic buffer device. Based on a preset impact buffer algorithm and the shock wave information, capsule adjustment information is obtained. Based on the capsule adjustment information, the capsule structure is adjusted to obtain the adjusted deep-sea measurement capsule, including: The temperature of the spring support device is controlled based on the shock wave information, so that the spring support device is adjusted to soften the spring based on the temperature, resulting in an adjusted spring support device, which then drives the hydraulic buffer device to move. Obtain the current hydraulic information of the hydraulic buffer device; The hydraulic buffer device is adjusted based on the shock wave information and the current hydraulic information to obtain the adjusted deep-sea measurement capsule.

[0016] In the above scheme, the temperature of the spring support device is controlled by shock wave information, thereby achieving dynamic adjustment of its elastic modulus and absorbing the impact energy. Then, the adjusted spring drives the hydraulic buffer device to move and make secondary adjustments, which can effectively cope with various impacts and provide all-round protection for the deep-sea measurement capsule, which is beneficial to the subsequent measurement of the deep-sea measurement capsule.

[0017] Further, the current hydraulic information includes current piston movement data and current hydraulic chamber pressure; the hydraulic buffer device includes a hydraulic cylinder, hydraulic oil, and a piston, the hydraulic cylinder is provided with an opening and a throttle orifice, the piston is provided in the opening, and the hydraulic oil is provided in the hydraulic chamber of the hydraulic cylinder; the other end of the spring support device is connected to the piston; the adjustment of the hydraulic buffer device based on the shock wave information and the current hydraulic information to obtain the adjusted deep-sea measurement capsule includes: The target damping force is determined based on the shock wave information; Based on the target damping force and the piston motion data, the target hydraulic chamber pressure is obtained; The opening degree of the throttle orifice of the hydraulic cylinder is controlled based on the target hydraulic chamber pressure and the current hydraulic chamber pressure, so that the hydraulic cylinder adjusts the flow rate of the hydraulic oil based on the opening degree, thereby adjusting the hydraulic chamber pressure of the hydraulic cylinder to the target hydraulic chamber pressure.

[0018] In the above scheme, the target damping force is determined by shock wave information, and the target hydraulic chamber pressure is derived by combining piston motion data. Finally, the flow rate and pressure of hydraulic oil are adjusted by precisely controlling the opening degree of the throttle orifice, so that the deep-sea measurement capsule can have sufficient rigid support to dissipate the impact under severe impact.

[0019] Another embodiment of the present invention provides a secure marine measurement data acquisition system, including a deep-sea measurement capsule, the secure marine measurement data acquisition system comprising: The acquisition module is used to acquire sea area information of the sea area to be measured; The sonar module is used to extract aggressive acoustic sonar signals from the sea area information and release an anti-phase acoustic sonar signal corresponding to the aggressive acoustic sonar signal. Shock wave module, used to extract shock wave information from the sea area information; The adjustment module is used to obtain capsule adjustment information based on a preset shock buffer algorithm and the shock wave information, and to adjust the capsule structure based on the capsule adjustment information to obtain the adjusted deep-sea measurement capsule. The measurement module is used to cancel the aggressive sonar signal based on the anti-phase sonar signal, and to acquire marine measurement data of the sea area to be measured based on the adjusted deep-sea measurement capsule.

[0020] Another embodiment of the present invention provides a terminal device, including: a processor, a memory, and a computer program stored in the memory and configured to be executed by the processor.

[0031] See Figure 1 To address the aforementioned problems and improve the security and reliability of acquiring marine measurement data, an embodiment of the present invention provides a secure method for acquiring marine measurement data, applied to a deep-sea measurement capsule. The method includes: Step S1: Obtain marine information of the sea area to be measured; Step S2: Extract the aggressive sonar signal from the sea area information and release the anti-phase sonar signal corresponding to the aggressive sonar signal. Step S3: Extract shock wave information from sea area information; Step S4: Based on the preset shock buffer algorithm and shock wave information, obtain capsule adjustment information, and adjust the capsule structure based on the capsule adjustment information to obtain the adjusted deep-sea measurement capsule; Step S5: The offensive sonar signal is canceled based on the anti-phase sonar signal, and the marine measurement data of the sea area to be measured is obtained according to the adjusted deep-sea measurement capsule.

[0032] In the aforementioned scheme, a corresponding anti-phase sonar signal is generated based on the aggressive sonar signal, thereby effectively canceling the aggressive sonar signal at the physical level. This makes the deep-sea measurement capsule acoustically invisible, effectively improving its concealment and survivability in the measured sea area and providing a safe environment for the deep-sea measurement capsule to measure marine measurement data. Simultaneously, the deep-sea measurement capsule's structure is adjusted based on shock wave information, ensuring that the capsule can reduce the impact of shock waves during measurement and maintain a stable and reliable marine measurement state. The synergistic effect of these two methods solves the problems of easy interruption, exposure, and impact-induced data failure in traditional marine measurement technologies, improving the safety and reliability of marine measurement data acquisition.

[0033] Furthermore, the outer shell of the deep-sea measurement capsule adopts an integrated multi-layer structure of titanium alloy-carbon fiber composite material, achieving a balance between lightweight and high compressive strength through a vacuum hot-pressing co-curing molding process. The main frame is cast from TC4 titanium alloy to form a load-bearing skeleton, with T800 grade carbon fiber reinforcement layers layered on the outer surface. A high-modulus epoxy resin system is used at the interface to enhance the interfacial bonding strength. According to the design pressure gradient, a gradient wall thickness structure is adopted in the axial and radial directions (outer layer thickness 2.5 mm, middle layer 1.2 mm, inner layer 0.6 mm), reducing the overall weight by more than 30% while ensuring compressive strength (≥120 MPa). To adapt to the high-pressure and high-salt environment of the deep sea, the shell surface is treated with a nano-ceramic oxide film and sprayed with a corrosion-resistant fluoropolymer coating, achieving an overall corrosion resistance life of more than 10 years.

[0034] In another embodiment, obtaining the sea area information of the sea area to be measured includes: Obtain capsule pressure sensing information from the deep-sea measurement capsule; Based on the pressure sensing information of the capsule, the target seabed is determined and nanofluid is released to construct a solidification layer between the deep-sea measurement capsule and the target seabed. The deep-sea measurement capsule is then fixed to the target seabed based on the solidification layer, thereby obtaining the sea area information.

[0035] It should be noted that a magnesium borate nanofluid reservoir and release control system is integrated at the bottom of the deep-sea measurement capsule. This system may include a pressure-sensitive trigger valve, a nanofluid release pump, and a reaction control unit for adjusting the nanofluid release rate. When the deep-sea measurement capsule is released into the sea area to be measured, when the bottom of the capsule's shell contacts the seabed, the pressure sensor inside the pressure-sensitive trigger valve detects the change in static pressure and obtains capsule pressure sensing information (preferably, the threshold is ≥0.2MPa). This confirms that the current landing location is the target seabed and automatically opens the nanofluid release channel. The nanofluid is mostly magnesium borate nanopowder. The magnesium borate nanopowder undergoes an ion exchange reaction with seawater to generate a colloidal solidified body. For example, a high-adhesion solidified layer with a thickness of about 8–12 mm can be formed within 30 minutes, and it works synergistically with the vacuum negative pressure adsorption chamber to increase the total anchoring force to 22–25 kN. The central control unit monitors the stress distribution and solidification layer formation status of the deep-sea measurement capsule shell in real time using strain sensors. Based on a finite element inversion algorithm, it calculates the bottom contact area and stress concentration region, and dynamically adjusts the nanofluid release rate and vacuum pump power to optimize the anchoring force distribution and the uniformity of the solidification layer thickness. When changes in seabed geological conditions are detected (such as differences between hard rock and soft mud), the release strategy is automatically switched (e.g., low-flow continuous release / high-flow rapid release) to ensure the anchoring force remains stable within the design range. In one embodiment, the method for adjusting the nanofluid release rate includes: determining the target seabed based on the capsule pressure sensing information and releasing the nanofluid to construct a solidification layer between the deep-sea measurement capsule and the target seabed. This solidification layer then fixes the deep-sea measurement capsule to the target seabed, thereby acquiring the marine information.

[0036] In another embodiment, the step of determining the target seabed based on the capsule pressure sensing information and releasing nanofluid to construct a solidification layer between the deep-sea measurement capsule and the target seabed based on the nanofluid, thereby fixing the deep-sea measurement capsule to the target seabed based on the solidification layer, and then acquiring the sea area information, includes: Based on the capsule pressure sensing information, the initial nanoflow rate of the nanofluid and the initial seabed information, current seabed information, initial porosity and current porosity of the target seabed are obtained; Based on the initial seabed information, current seabed information, initial porosity, and current porosity, determine the current nanoflow rate; The nanofluid is released based on the current nanoflow rate until the solidified layer is constructed.

[0037] It should be noted that the magnesium borate nanofluid release system integrated at the bottom of the deep-sea measurement capsule works in conjunction with the pressure-sensitive triggering unit: when the pressure sensor inside the pressure-sensitive triggering valve at the bottom of the deep-sea measurement capsule detects a seabed contact signal (≥0.2 MPa) and obtains the capsule's pressure sensing information, the deep-sea measurement capsule starts the nanofluid release pump, in which the initial nanoflow rate... The flow rate can be preferably set to 0.10~0.15 mL / min to inject fluid at an initial nanometer flow rate, and Q(t) can be calculated based on the current seabed information (current seabed hardness) H and the current porosity M, thereby automatically adjusting the release curve. ; Where Q(t) is the current nanometer flow rate, and α and β are preset empirical adjustment coefficients. Standard seabed hardness (i.e., initial seabed information). This is the standard porosity (i.e., the initial porosity).

[0038] In another embodiment, the step of determining the target seabed based on the capsule pressure sensing information and releasing nanofluid to construct a solidification layer between the deep-sea measurement capsule and the target seabed based on the nanofluid, thereby fixing the deep-sea measurement capsule to the target seabed based on the solidification layer, and then acquiring the sea area information, includes: Obtain the curing information of the cured layer; The degree of curing of the cured layer is determined based on the curing information; When the curing degree is complete, the gap between the cured layer and the target seabed is suctioned until the negative pressure value between the cured layer and the target seabed is within a preset negative pressure range, and then the sea area information is obtained.

[0039] It should be noted that the continuous release of nanofluid until a solidified layer is formed is used to determine whether the solidified layer has been successfully constructed. The method for determining the success of solidification is as follows: Solidification information of the solidified layer is obtained. This information includes embedded conductivity and acoustic impedance sensing signals from an embedded conductivity sensor. Embedded conductivity measures the concentration of freely moving ions in the solution, while acoustic impedance describes the resistance encountered by sound waves propagating through a medium. During the solidification process, this solidification information changes. Therefore, the progress of the solidification reaction can be monitored in real time using the embedded conductivity and acoustic impedance sensors. When the conductivity drops to 40% of its initial value and the acoustic impedance increases to 2.0–2.3 MRayl, the solidified layer is considered complete (approximately 30 ± 2 min). After this stage, the solidified layer thickness is approximately 8–12 mm, forming a highly adhesive interface with the target seabed. The deep-sea measurement capsule can also be equipped with a micro-vortex vacuum pump to extract interstitial gas and establish a negative pressure chamber. After the solidified layer is formed, the micro-vortex vacuum pump is activated to extract the interstitial gas between the solidified layer and the target seabed. The pressure sensor on the deep-sea measurement capsule measures the pressure P inside the negative pressure chamber in real time, continuously adjusting the suction level of the vacuum pump to maintain the negative pressure chamber and the negative pressure tolerance value within a preset negative pressure range: P. target =P-ΔP, ΔP=0.05~0.08MPa, P target The preset negative pressure range is defined by ΔP, which represents the "negative pressure difference / pressure margin" that the negative pressure chamber must maintain to ensure reliable and stable anchoring of the solidified layer. For example, when the negative pressure chamber is stably maintained at ≥0.07 MPa and the shear modulus of the interface between the solidified layer and the target seabed reaches the design value (preferably ≥4.2 MPa), the total anchoring force can be increased to 22–25 kN.

[0040] In another embodiment, the step of extracting offensive sonar signals from the sea area information and releasing anti-phase sonar signals corresponding to the offensive sonar signals includes: The characteristics of the offensive sonar are determined based on the offensive sonar signal. Based on the preset acoustic superposition algorithm and the characteristics of the offensive acoustic sonar, a reverse signal parameter set is obtained; The anti-phase sonar signal is obtained based on the preset anti-phase signal generation algorithm and the inverse signal parameter set.

[0041] It should be noted that for the deep-sea measurement capsule to achieve active stealth, a sonar jamming module is first required. This module consists of a sonar signal monitoring unit, a signal processing unit, and a jamming signal transmission unit, and achieves active stealth control through three steps: feature extraction, parameter inversion, and reverse signal synthesis. The marine information acquired by the deep-sea measurement capsule includes aggressive sonar signals. These signals are acquired as follows: the sonar signal monitoring unit uses a 0.1–100kHz broadband hydrophone array to collect the aggressive sonar signal s(t) in real time. The collected aggressive sonar signal first undergoes bandpass filtering and noise reduction to remove ocean current disturbances and background noise. The signal processing unit uses short-time Fourier transform (STFT) and envelope demodulation algorithms to perform time-frequency domain decomposition of the aggressive sonar signal, extracting the main aggressive sonar features: the dominant frequency... Determined by the position of the power spectrum peak; phase : Obtained from the argument of the complex spectral components; amplitude : Extracted from the peak value of the amplitude-frequency response; Waveform envelope E(t): calculated through Hilbert transform; Direction of arrival θ: inverted using the multi-point time difference of arrival or phase gradient method; The signal processing unit obtains the reverse signal parameter set based on the preset acoustic wave superposition algorithm and the characteristics of the offensive acoustic sonar. , , ): ; ; ; in, An amplitude matching coefficient (0.9–1.1, adjustable according to the target acoustic field) is used to ensure that the canceling wave and the incident wave have similar amplitudes but opposite phases, thereby maximizing the destructive interference effect. Then, based on a preset anti-phase signal generation algorithm and the inverse signal parameter set, the anti-phase acoustic sonar signal is obtained. The preset inverted signal generation algorithm is as follows: = ; By using phased array control to adjust the wavefront direction, the interference wave corresponding to the anti-phase sonar signal encounters and superimposes with the incident wave corresponding to the offensive sonar signal along the sound field propagation path, thereby canceling out the intensity of the offensive sonar signal. Furthermore, the residual sound pressure of the incident wave can be monitored in real time via a feedback loop. and according to Adjustment and This enables dynamic compensation. For example, experimental results show that the above method can reduce the intensity of the detected echo of the incident wave corresponding to the offensive sonar signal by ≥20dB and shorten the detection distance by more than 40%.

[0042] Furthermore, to achieve active stealth, the deep-sea measurement capsule can also incorporate an electromagnetic shielding module within its outer shell. This module employs a three-layer composite shielding material, with each layer designed to absorb electromagnetic signals at different frequencies. These layers are arranged sequentially from the inside out and bonded together with conductive adhesive. The three layers are arranged according to their frequency absorption principles: the inner iron-nickel alloy soft magnetic layer absorbs low-frequency (<10MHz) magnetic fields; the middle conductive silicone rubber layer suppresses mid-frequency (10–100MHz) interference; and the outer silver-plated nylon layer reflects high-frequency (>100MHz) signals. The layers are bonded together with conductive silver paste, forming a continuous conductive path to prevent leakage through gaps. Simultaneously, an active electromagnetic cancellation coil is installed within the module. By detecting electromagnetic leakage signals inside the capsule, it generates a reverse electromagnetic signal to cancel them out, effectively shielding a wide range of electromagnetic signals.

[0043] In another embodiment, the deep-sea measurement capsule includes an outer shell, a spring support device, and a hydraulic buffer device. The inner wall of the outer shell is connected to one end of the spring support device; the other end of the spring support device is connected to the hydraulic buffer device. The capsule adjustment information is obtained based on a preset impact buffer algorithm and the shock wave information. The capsule structure is then adjusted based on the adjustment information to obtain the adjusted deep-sea measurement capsule, comprising: The temperature of the spring support device is controlled based on the shock wave information, so that the spring support device is adjusted to soften the spring based on the temperature, resulting in an adjusted spring support device, which then drives the hydraulic buffer device to move. Obtain the current hydraulic information of the hydraulic buffer device; The hydraulic buffer device is adjusted based on the shock wave information and the current hydraulic information to obtain the adjusted deep-sea measurement capsule.

[0044] It should be noted that the ocean information acquired by the deep-sea measurement capsule also includes shock wave information. When the deep-sea measurement capsule is released and lands on the seabed, or is attacked by marine life, it is highly likely to be impacted. Therefore, the deep-sea measurement capsule needs effective shock absorption, which requires a spring support device. The spring support device uses shape memory alloy springs, which are evenly distributed inside the capsule's outer shell and connected to the outer shell via a connecting seat made of high-strength material with excellent cushioning performance. When the deep-sea measurement capsule is subjected to impact, the shape memory alloy springs undergo elastic deformation, absorbing the energy of the impact. The deep-sea measurement capsule can measure the impact force F(t) in real time using piezoelectric impact sensors and strain gauge arrays, as well as the acceleration a(t) and shell strain ε(t) from the shock wave information. The deep-sea measurement capsule adjusts the preload state of the elastic support device based on an impact force threshold determination and dynamic adjustment algorithm: when the shock wave information exceeds the set impact force threshold... (The preferred typical value is 2.5–3.0 kN), the phase transition temperature of the shape memory alloy is adjusted in the deep-sea measurement capsule. (Through fine-tuning via electric current heating), the martensite / austenite phase ratio is changed, thereby dynamically altering the elastic modulus of the spring support device within milliseconds to obtain the current elastic modulus. : ; in: : Baseline elastic modulus; ΔE: Adjustable range of elastic modulus due to temperature phase change; The impact-temperature response function is a mapping relationship pre-defined based on prior knowledge. In this way, the elastic support device can automatically "soften" or "strengthen" according to shock wave information of different impact intensities, resulting in an adjusted spring support device. This adjusted spring support device then drives the hydraulic buffer device to move, achieving adaptive absorption and rapid recovery of primary impact energy.

[0045] In another embodiment, the current hydraulic information includes current piston movement data and current hydraulic chamber pressure; the hydraulic buffer device includes a hydraulic cylinder, hydraulic oil, and a piston, the hydraulic cylinder having an opening and a throttle orifice, the piston being disposed in the opening, and the hydraulic oil being disposed in the hydraulic chamber of the hydraulic cylinder; the other end of the spring support device is connected to the piston; adjusting the hydraulic buffer device based on the shock wave information and the current hydraulic information to obtain the adjusted deep-sea measurement capsule includes: The target damping force is determined based on the shock wave information; Based on the target damping force and the piston motion data, the target hydraulic chamber pressure is obtained; The opening degree of the throttle orifice of the hydraulic cylinder is controlled based on the target hydraulic chamber pressure and the current hydraulic chamber pressure, so that the hydraulic cylinder adjusts the flow rate of the hydraulic oil based on the opening degree, thereby adjusting the hydraulic chamber pressure of the hydraulic cylinder to the target hydraulic chamber pressure.

[0046] It should be noted that to achieve shock absorption, the deep-sea measurement capsule also requires a hydraulic buffer device: this device includes a hydraulic cylinder, hydraulic oil, and a piston. The piston surface undergoes wear-resistant treatment, and the hydraulic oil is filled to a certain volume. When subjected to a large impact force, driven by the spring support device, the piston moves within the hydraulic cylinder. The hydraulic oil, through a throttling orifice, generates a damping effect, dissipating the energy of the impact force and effectively reducing the peak impact force. Specifically: First, there is a mapping relationship between impact kinetic energy and damping force. The impact kinetic energy is: ; in, The equivalent mass of the deep-sea measurement capsule in the impact direction is determined by the mass of the deep-sea measurement capsule itself and its constraint relationship with the buffer structure; To measure the relative impact velocity between the deep-sea measuring capsule and the target seabed at the moment of contact, the acceleration signal can be measured by an accelerometer. The result is obtained by time integration.

[0047] The hydraulic buffer device adopts a viscous damping model, and its instantaneous damping force satisfy: ; in, The instantaneous velocity of the piston (piston speed). This is the instantaneous damping coefficient. The work done (i.e., energy dissipated) by the damping device during the entire impact process is: ; To ensure impact cushioning and avoid excessive deceleration, this invention presupposes that a portion of the impact kinetic energy is stored by the spring support device, and the other portion is consumed by the hydraulic damping of the hydraulic buffer device, i.e.: ; in The preset proportionality coefficient takes a value between 0 and 1. Based on the above relationship, the energy dissipated in the band is... Then, based on the dissipated energy The damping force can be determined by the obtained piston speed. Impact kinetic energy By establishing a certain mapping relationship between dissipated energy and damping force, and further, by pre-calibrating through experiments or simulations, and Function mappings or table lookup relationships between them.

[0048] In the current scheme, the hydraulic buffer device can monitor the current hydraulic information of the hydraulic cylinder in real time through micro-pressure sensors and displacement sensors: including the current hydraulic chamber pressure P(t) and the current piston motion data (i.e., the current piston speed). The deep-sea measurement capsule determines the target damping force based on the shock wave information, which includes the current impact kinetic energy. Specifically, based on a preset mapping relationship between impact kinetic energy and damping force, the target damping force is obtained according to the current impact kinetic energy and the current piston speed. The target hydraulic chamber pressure is obtained based on the target damping force and current piston motion data, according to the following formula: ; We can deduce that: ; in The target is a dynamically adjustable damping coefficient. Because the formula exists: ,in Initial damping coefficient; : Static pressure of the hydraulic chamber; k: Preset adjustment coefficient. Therefore, after obtaining the current hydraulic chamber pressure P(t), depending on... This allows us to obtain the current dynamically adjustable damping coefficient. (t).

[0049] when (t) is not equal to When (t), the deep-sea measurement capsule adjusts the orifice opening (i.e., the orifice degree) A(t) of the hydraulic cylinder through a micro-electronic valve array, thereby achieving the measurement of... The adaptive adjustment of (t) to make (t) equals (t) indicates that the hydraulic chamber pressure has been adjusted to make the current hydraulic chamber pressure in the hydraulic cylinder equal to the target hydraulic chamber pressure. When the impact in the shock wave information is too large, the current impact kinetic energy will also increase, so the throttle orifice area is reduced to increase the damping force; when the impact is small, the current impact kinetic energy will also decrease, so the throttle orifice is enlarged to avoid excessive rigidity and maintain the elastic response of the system.

[0050] Furthermore, the aggressive sonar signal is canceled out by the anti-phase sonar signal, and marine measurement data of the target sea area is acquired based on the adjusted deep-sea measurement capsule, ensuring the safe and reliable acquisition of marine measurement data. The deep-sea measurement capsule is equipped with a fiber optic grating array (strain monitoring) and a diamond NV color center quantum magnetic sensor (geomagnetic monitoring), encapsulated within a zirconia ceramic probe. Data collected by the sensors within the deep-sea measurement capsule is transmitted to the data processing module, and the processed data is stored in a memory chip. The wireless communication module of the deep-sea measurement capsule employs a combination of underwater acoustic communication and satellite communication, enabling real-time transmission of measurement data to a surface receiving device.

[0051] Furthermore, when the deep-sea measurement capsule receives a recovery command or triggers a self-destruct process, it enters the detachment phase. First, the capsule's electrically controlled injection pump injects alkaline electrolyte into the solidified layer. The control system adjusts the injection rate based on the solidified layer strength decay curve fed back by strain sensors, ensuring that the solidified layer is destroyed by ≥95% within 2.5–3 minutes. Subsequently, a micro-pump fills the negative pressure chamber with high-pressure nitrogen, rapidly breaking down the negative pressure adsorption and completing the release of the deep-sea measurement capsule. The capsule detects the rate of decrease in anchoring force using force sensors. When a residual adsorption force of <2kN is detected, it automatically cuts off the suction and injection channels and activates the attitude control system to assist in the capsule's detachment. More specifically, the deep-sea measurement capsule is equipped with a triggering device, including a time triggering unit, a task completion triggering unit, and a remote command triggering unit. The time-triggered unit uses a timer to trigger the self-destruct system according to a preset time. The task completion trigger unit monitors the data acquisition and processing status of the measurement system and triggers the self-destruct system when preset task completion conditions are met. The remote command trigger unit uses an encrypted wireless communication module to receive self-destruct commands from the surface control center, ensuring the accuracy of command transmission. The deep-sea measurement capsule is also equipped with a destruction device: a pre-embedded electrolytic dissolution unit, a magnesium-aluminum alloy mesh as the anode and a titanium alloy pillar as the cathode inside the shell, and is equipped with electrolyte and preset energizing parameters. The deep-sea measurement capsule is also equipped with an information erasure device: a strong magnetic field generator and heating device are used to completely erase the data in the storage chip; 40% hydrofluoric acid is injected into the quantum sensor probe to completely dissolve the chip.

[0052] Furthermore, the deep-sea measurement capsule is equipped with an energy supply system: this system combines lithium batteries and a small ocean thermal energy conversion device (OTEC). The lithium batteries provide power to the capsule during the initial stages and in low-energy-consumption operation; the miniature OTEC utilizes the temperature difference between the deep sea and surface water to generate electricity, providing a continuous and stable energy supply for the capsule's long-term operation. Once the capsule reaches its operating depth, the OTEC automatically activates, prioritizing power to the deep-sea measurement capsule. When the power output is insufficient, the lithium batteries automatically switch power, with both working in tandem to extend mission duration. A supercapacitor bank is also added to provide pulsed current to support electrolytic dissolution during the self-destruct phase.
