Description

Technical Field

[0001] The present invention belongs to the technical field of deep-sea data center control, and relates to a dynamic buoyancy adjustment and balance control method for a deep-sea suspended data center. Background Art

[0002] With the rapid development of information technology, data center energy consumption and heat dissipation have become key bottlenecks hindering the industry's development. Traditional data centers rely on mechanical refrigeration systems for cooling, which consumes over 40% of their total operating costs and produces significant amounts of greenhouse gases. To address this challenge, deep-sea suspended data centers have emerged. By utilizing the low temperatures of the deep ocean for natural cooling, they offer significant advantages in energy conservation and environmental protection.

[0003] However, the complexity and dynamism of the deep-sea environment place extremely high demands on the suspension stability of data centers. Deep-sea areas are subject to irregular ocean currents, drastic changes in water pressure, and interference from biological activities, requiring data centers to have real-time and precise buoyancy adjustment capabilities to maintain the predetermined depth and posture. Existing buoyancy adjustment technologies are mostly concentrated in the field of small underwater equipment, such as the single adjustment method of ballast tanks or airbags used by autonomous underwater vehicles. Although such technologies perform well in small devices, they expose obvious defects when applied to large data centers: First, the response speed of a single buoyancy adjustment method is insufficient and cannot cope with the instantaneous mutations of the deep-sea environment; second, the drainage cycle of traditional ballast tanks is as long as several minutes, making it difficult to achieve rapid balancing; third, the existing system lacks redundant design, and failure of key components can easily lead to overall failure, posing a major safety hazard.

[0004] In particular, existing patented technologies, such as the buoyancy adjustment device proposed in Patent No. CN202211518532.5, although it integrates communication functions and optimizes the buoyancy control of small equipment, the single ballast adjustment mode it adopts is insufficient in adjustment accuracy when dealing with multi-dimensional imbalances in large data centers. At the same time, such devices do not consider the coordinated control of distributed buoyancy units, resulting in the inability to quickly compensate for local stress concentration. In addition, existing methods generally lack a forward-looking adjustment mechanism, and the passive control mode that relies solely on sensor feedback is difficult to offset the lag effect of deep-sea fluids and is prone to causing system oscillations.

[0005] Therefore, there is an urgent need for a dynamic buoyancy balance control method with fast response, high-precision adjustment, redundant fault tolerance and active prediction capabilities to solve the stability control problem of deep-sea suspended data centers in complex marine environments.

[0006] In view of this, the purpose of the present invention is to provide a dynamic buoyancy adjustment and balance control method for a deep-sea suspended data center, aiming to solve the problems of slow buoyancy adjustment speed, low accuracy, slow response and lack of redundant design in the existing technology through efficient buoyancy adjustment methods and modular design, so as to achieve stable suspension and safe operation of the data center in a complex marine environment.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] A dynamic buoyancy adjustment and balance control method for a deep-sea suspended data center comprises the following steps:

[0009] Step 1: Acquire attitude data in real time through the inertial measurement unit 7 installed in the center of the data center cabin 1, and monitor the status parameters of the ballast water tank 6 and the inflatable airbag 4 at the same time;

[0010] Step 2: Build an ocean current prediction model based on the long short-term memory network (LSTM), inputting real-time ocean current data and historical 72-hour ocean environmental parameters;

[0011] Step 3: The control unit 8 coordinates and controls the gas compressor 12 to inject high-pressure air into the inflatable airbag 4 according to the prediction result, and adjusts the water discharge of the sea valve 5 and the solenoid valve 9 of the ballast water tank 6;

[0012] Step 4: When excess buoyancy is detected, the vacuum pump 10 is started to extract the air bag gas and control the ballast water tank 6 to be filled with water;

[0013] Step 5: Perform local balance compensation through at least three groups of independent buoyancy adjustment modules distributed circumferentially;

[0014] Step 6: Trigger the safety protection mechanism including the emergency pressure relief valve and redundant control system;

[0015] Step 7: Monitor the tension of anchor cable 2 through the optical fiber strain sensor and dynamically adjust the output of the corresponding buoyancy unit.

[0016] Furthermore, in step 1, the calibration of the inertial measurement unit 7 includes:

[0017] Perform zero drift compensation in static state;

[0018] Verify attitude accuracy through three-dimensional angular velocity integration;

[0019] The pressure sensor data is used to correct the depth measurement error.

[0020] Furthermore, in step 2, the input layer of the LSTM ocean current prediction model contains three-dimensional time series data of flow velocity, flow direction, and water temperature, and the output layer provides the ocean current vector prediction value for the next hour. The model hidden layer is set with 128 neurons and uses the tanh activation function.

[0021] Furthermore, in step 3, the collaborative control satisfies:

[0022] When the predicted ocean current intensity increases by ΔV, the airbag inflation volume is adjusted according to the formula Q = k·ΔV·A, where Q is the high-pressure air flow rate in m 3 / s, K is the adjustment coefficient, A is the projected area of the data center, unit is m 2 ;

[0023] Synchronously control the ballast water tank displacement W = ρ·Q·t, where ρ is the seawater density in kg / m 3 , t is the adjustment time, unit is s.

[0024] Furthermore, in step 5, the buoyancy adjustment module includes:

[0025] The cylindrical inflatable airbag 4 is coupled to the annular ballast water tank 6 via a titanium alloy connecting ring to form an axially overlapping composite structure;

[0026] The independently controlled gas compressor 12 branches and vacuum pump 10 branches are connected to the air bag through pressure-resistant bellows;

[0027] A three-way joint is provided at the bottom of the ballast water tank 6 and is connected to the sea valve 5 and the high-pressure gas valve group, and the top vent valve group is connected to the pressure balance tank.

[0028] Furthermore, in step six, the security protection mechanism includes:

[0029] When the airbag pressure is ≥1.5MPa, open the emergency pressure relief valve and activate the standby ballast water tank;

[0030] When the ballast water tank level exceeds the limit, the three-level sound and light alarm is activated and the redundant controller 8 is switched on.

[0031] Furthermore, in step seven, the tension adjustment of the anchor cable 2 includes:

[0032] When the tension deviation of a single anchor cable exceeds 30%, the output power of the corresponding buoyancy module is increased by 20%;

[0033] After the tension balance is restored, it gradually returns to the reference working point according to the exponential decay curve.

[0034] Furthermore, the control unit 8 adopts a dual CAN bus architecture, including:

[0035] The main controller and the backup controller synchronize key parameters in real time, including airbag pressure, water tank level, and attitude angle data;

[0036] The fault switching mechanism ensures that when the main control fails, the control right transfer is completed within 50ms, and the attitude fluctuation during the switching process is ≤0.3°.

[0037] Furthermore, the adjustment balance control method also includes a regular self-check process:

[0038] Automatically perform airbag 4 sealing test every 24 hours, including pressure holding test and leakage rate test;

[0039] The solenoid valve 9 response test includes full open / full close cycle test and step response characteristic analysis;

[0043] 4 sets of axial reinforcement ribs, 8mm thick and 15mm high;

[0044] The surface is plasma sprayed with a 0.2mm thick alumina ceramic anti-corrosion layer.

[0045] The beneficial effects of the present invention are:

[0046] (1) Through the coordinated linkage mechanism of the ballast water tank and the inflatable airbag, it can respond to the instantaneous changes of deep ocean currents in real time, achieve millisecond-level buoyancy dynamic compensation, and effectively suppress the attitude drift of the data center.

[0047] (2) Combining the high-frequency attitude feedback of the inertial measurement unit with the forward-looking adjustment of the ocean current prediction model, the output of each buoyancy unit can be accurately distributed to ensure the suspension stability of the data center in a complex fluid environment.

[0048] (3) Adopting intelligent regulation strategy and gas-liquid dual-phase coordinated control can avoid unnecessary power consumption of traditional single regulation mode and reduce energy consumption while maintaining stability.

[0049] (4) The modular design of the distributed buoyancy unit supports rapid compensation of local imbalances. Through independent control and coordinated operation of multiple units, it can flexibly respond to ocean current impacts and mechanical stress anomalies in different directions.

[0050] (5) The dual redundant control architecture is combined with multiple safety protection mechanisms to ensure that the system can maintain basic functions when key components fail, greatly reducing the operation and maintenance risks in deep-sea environments.

[0051] (6) The forward-looking ocean current prediction is combined with dynamic buoyancy pre-regulation to effectively offset the lag effect of deep-sea fluids and avoid the system oscillation problem caused by the traditional passive control mode.

[0052] (7) The mechanical coupling layout of the airbag and the ballast water tank takes into account both space utilization and regulation efficiency, and realizes the integrated deployment of multi-dimensional buoyancy regulation functions within the limited cabin space.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0062] The working principle of the present invention is as follows: first, a high-pressure air source provides power, and a gas compressor is used to inject high-pressure air into the inflatable airbag, causing it to expand and expel seawater, thereby increasing buoyancy. At the same time, the sea valve at the bottom of the ballast water tank and the high-pressure air pipeline solenoid valve are opened, allowing high-pressure air to enter the ballast tank and discharge the ballast water outside the tank, further reducing the gravity of the data center and increasing buoyancy. Secondly, when buoyancy needs to be reduced, the high-pressure air pipeline solenoid valve is closed, and the vent solenoid valve at the top of the ballast tank and the sea valve at the bottom are opened, allowing seawater to flow into the ballast tank under the action of the pressure difference to increase gravity. At the same time, the air bag's vent valve is opened, and the gas in the airbag is discharged with the help of a vacuum pump, allowing seawater to reoccupy the airbag space to reduce buoyancy. Finally, the inertial measurement unit monitors the attitude and motion status of the data center in real time, providing data such as acceleration, angular velocity, and attitude angle. The ocean current prediction model provides predicted data on ocean current changes based on historical data and real-time sensor input. The control unit integrates this information, controls the action of the solenoid valve, vacuum pump, and breather valve, realizes dynamic balance control, and adjusts the buoyancy in real time according to ocean current changes and the attitude of the data center, ensuring the stable operation of the data center in complex marine environments.

[0063] See also Figures 1 to 3In this embodiment, the dynamic buoyancy adjustment and balance control method for a deep-sea suspended data center is described. A high-pressure air source 11 and a gas compressor 12 are installed within the data center's support area, near the buoyancy adjustment system, to facilitate pipe 13 connection and maintenance. Anchor cables 2 are connected to the seabed foundation via titanium alloy anchoring devices 3, and their stress distribution is monitored in real time by fiber optic sensors. Ballast tanks 6 are distributed across the bottom of the data center and designed as multiple independent units for center of gravity adjustment and buoyancy control. Inflatable airbags 4 are installed at appropriate locations outside the data center and connected to the gas compressor 12 and vacuum pump 10 via flexible pipes 13, ensuring that their expansion and contraction do not affect the normal operation of the data center. A seawater valve 5 is installed at the bottom of the ballast tank 6, providing reliable sealing and remote control capabilities to ensure smooth seawater inflow and outflow. A vacuum pump 10 is installed within the support area and connected to the airbag's deflation pipe to quickly exhaust the air within the airbag. An inertial measurement unit 7 is installed in the center of the data center and near key buoyancy units to obtain accurate attitude and motion data. The control unit 8 is installed in the control room and integrates the inertial measurement unit data, ocean current prediction model and buoyancy adjustment method to achieve automatic control.

[0064] Specifically, the high-pressure air source 11 stably supplies high-pressure air to the system, and the gas compressor 12 injects high-pressure air into the inflatable airbag 4, causing it to expand and discharge seawater to increase buoyancy. At the same time, the ballast water tank 6 increases buoyancy by reducing gravity through drainage. The two work together to quickly respond to changes in buoyancy demand. The high-pressure air pipeline solenoid valve 9 accurately controls the flow of high-pressure air into the ballast water tank 6 to achieve fine adjustments in buoyancy, while the seawater valve 5 controls the flow of seawater into or out of the ballast water tank 6 to ensure its stable operation. When it is necessary to reduce buoyancy, the vacuum pump 10 extracts gas from the airbag, causing the airbag to shrink rapidly, and seawater flows back into the airbag space to achieve a rapid reduction in buoyancy. During this process, the inertial measurement unit 7 collects data such as acceleration, angular velocity, and attitude angle of the data center in real time, providing accurate feedback to the control unit 8. The control unit 8 integrates the IMU data with the ocean current prediction model, and intelligently controls the solenoid valve 9, vacuum pump 10, etc. to achieve dynamic buoyancy balance control. The present invention synergizes components such as the high-pressure air source 11, gas compressor 12, inflatable airbags 4, and ballast tanks 6, combined with ocean current prediction models and real-time data from an inertial measurement unit 7, to achieve efficient and precise buoyancy adjustment. The ballast tanks 6 and inflatable airbags 4 are linked to rapidly respond to changes in ocean currents and waves. The inertial measurement unit 7, combined with the ocean current prediction model, precisely controls buoyancy distribution. The independent configuration of distributed buoyancy units allows for flexible adaptation to localized imbalance scenarios. A comprehensive safety protection mechanism ensures stable operation of the system in complex ocean environments.

[0065] The following describes the specific operating steps of the dynamic buoyancy adjustment and balance control method of the deep-sea suspended data center:

[0066] Step 1: Turn on the inertial measurement unit 7, perform a self-test and calibrate the zero point to ensure the accuracy of the sensor data.

[0067] Step 2: Check whether the connection of the inertial measurement unit 7 is firm to ensure the stability of data transmission.

[0068] Step 3: Input real-time data about the current ocean environment, including current velocity, direction, and temperature, to calibrate the current prediction model to ensure accuracy. During calibration, the model's predicted values are compared with actual measurements, and model parameters are adjusted to improve prediction accuracy.

[0069] Step 4: Check the ballast water tank 6, inflatable air bag 4, high-pressure air pipe 13 for leaks. Use pressure testing equipment to pressurize each component to check for air or water leaks.

[0070] Step 5: Check the operating status of the high-pressure air source 11 and the gas compressor 12 to ensure they are functioning properly. Check the operating status of the vacuum pump to ensure it can quickly exhaust the gas in the airbag. Check the connection and communication status of the control unit to ensure it can receive and process sensor data in real time.

[0071] Step 6: Start the air compressor 12 and inject high-pressure air into the inflatable airbag 4. Observe the expansion of the airbag and record the pressure and volume changes. Open the airbag 4's deflation valve and use the vacuum pump 10 to expel the air from the airbag. Observe the contraction of the airbag 4 and record the pressure and volume changes.

[0072] Step 7: Open the sea valve 5 at the bottom of the ballast tank 6 and the high-pressure air line solenoid valve 9 to allow high-pressure air to enter the ballast tank 6 and drain the ballast water out of the tank. Record the drainage rate and water level changes. Close the high-pressure air line solenoid valve 9, open the vent solenoid valve at the top of the ballast tank and the sea valve 5 at the bottom, allowing seawater to flow into the ballast tank due to the pressure differential, and record the water filling rate and water level changes.

[0073] Step 8: Based on the data provided by the ocean current prediction model, simulate ocean current changes of different strengths and directions and observe the response of the data center.

[0074] Step 9: When the simulated current strengthens or waves impact the data center, the control unit 8 instructs the ballast tanks 6 to fill with water to increase weight and the airbags 4 to deflate to reduce buoyancy. The data center's return to the desired depth and the process data are recorded. When the simulated current weakens or the waves decrease, the control unit 8 instructs the ballast tanks 6 to drain to reduce weight and the airbags 4 to inflate to increase buoyancy. The data center's stability and response time at the target location are recorded.

[0075] Step 10: Conduct individual control tests on the independent buoyancy adjustment units equipped in each compartment of the data center, including the inflation and deflation operations of the small ballast water tank 6 and the inflatable airbag 4, to observe the response of each unit and its impact on the overall balance.

[0076] Step 11: During the test, use the sensor data acquisition device to collect real-time data from each sensor, including pressure, liquid level, acceleration, angular velocity, attitude angle, etc. Analyze the collected data to evaluate the performance of the buoyancy adjustment method, including response speed, adjustment accuracy, and method stability. Optimize and adjust the method based on the analysis results.

[0077] Example 1: Rapid buoyancy response to sudden ocean current changes

[0078] 1. When the inertial measurement unit detected a sudden 2° pitch angle offset and 0.15m / s vertical acceleration in the data center, the control unit interpreted it as an imbalance caused by the impact of ocean currents.

[0079] 2. Start the gas compressor to inject high-pressure air into the southeast airbag at a flow rate of 200L / s, and at the same time open the corresponding solenoid valve at the bottom of the ballast water tank to drain water.

[0080] 3. The ocean current prediction model adjusts the parameters based on real-time flow rate data, increasing the airbag inflation volume to 120% of the preset value.

[0081] 4. Module 3 of the distributed buoyancy unit completes airbag inflation first, discharging 8m of ballast water within 5 seconds 3 , restoring the data center to a horizontal posture

[0082] 5. The control unit continuously monitors attitude data and switches to fine-tuning mode when the pitch angle error is ≤0.5°, accurately controlling the airbag pressure through the proportional valve.

[0083] Example 2: Preventive Regulation Driven by Ocean Current Prediction

[0084] 1. Based on historical data analysis, the ocean current prediction model issued a 40-minute advance warning of a 1.2 m / s increase in current speed in the northwest direction.

[0085] 2. The control unit initiates the preparatory command: empty the northwest ballast tank to 10% of its capacity and pre-fill the southeast airbag to 80% of its rated capacity.

[0086] 3. When the flow rate actually increases to 1.1m / s, the ratio of the airbag deflation rate and ballast water injection volume in the northwest area is adjusted in real time to 1:1.5

[0087] 4. Synchronously activate the No. 4 and No. 7 redundant buoyancy units to offset the impact of periodic waves in an alternating working mode with a phase difference of 120 degrees

[0088] 5. After verifying the tension balance of anchor cable 2 through optical fiber strain sensor, maintain closed-loop feedback adjustment of prediction model and control instructions

[0089] Example 3: Triggering method of three-level security protection mechanism

[0090] The No. 1.5 airbag pressure sensor detected an overpressure of 1.55 MPa, triggering a level 1 alarm.

[0091] 2. The safety logic unit performs emergency response:

[0092] The airbag emergency pressure relief valve opens within 0.5 seconds, with a release rate of 300L / s

[0093] Activate the spare ballast water tank and fill it with water at a rate of 200kg / s to increase the weight.

[0094] Close the gas supply line of the faulty module and switch to the redundant gas source

[0095] 3. When the liquid level continues to rise to Hmax+5%, the three-level alarm is activated:

[0096] Cut off the power supply to the area and activate the backup hydraulic drive system

[0097] Send fault codes to shore-based control center via satellite link

[0098] 4. Stabilize the airbag pressure to a safe range of 1.2MPa within 12 seconds

[0099] 5. Critical services were not interrupted during the incident handling, verifying the effectiveness of the protection mechanism

[0100] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions, which should all be included in the scope of the claims of the present invention.
