[0018] Example 1, please refer to Figure 1 -picture Figure 3 , main control cabin, the main control cabin has built-in data processing module, energy storage battery and communication module, the communication module includes underwater acoustic communication unit and satellite relay unit; the main control cabin serves as the core hub of the entire monitoring device, providing a stable and safe operating environment for data processing, energy storage and communication, the data processing module can efficiently analyze and process the massive data collected by the sensor in real time; the energy storage battery provides continuous and stable power support for each component of the device; the underwater acoustic communication unit and the satellite relay unit are combined to build a full-dimensional, multi-level communication network, the underwater acoustic communication unit is suitable for short-distance transmission of underwater data, and can stably transmit data in a complex ocean acoustic environment; the satellite relay unit realizes remote communication between deep-sea data and shore-based centers; Sensor array: The sensor array is distributed outside the cabin. The sensor array includes at least a CO2 concentration sensor, a pressure sensor, a temperature sensor, a pH sensor and an ocean current velocity meter. The sensor array is electrically connected to the data processing module. The CO2 concentration sensor can monitor the concentration of carbon dioxide on the seabed in real time, providing a direct data basis for evaluating the carbon dioxide storage effect and leakage risk. The pressure sensor can accurately measure the water pressure changes on the seabed, which helps to understand the stability of the seabed geological structure and the dynamic changes of the marine environment. The temperature sensor can monitor the changes in seabed water temperature, which is of great significance for studying marine ecosystems and climate change. The pH sensor can detect the pH of seawater, reflecting the changes in the chemical properties of the marine environment, which is crucial for evaluating the impact of carbon dioxide leakage on the marine ecology. The ocean current velocity meter can measure the speed and direction of ocean currents, providing important data for studying ocean circulation and material transport. The image acquisition unit is located outside the main control cabin and is equipped with a high-definition camera and a fill light device to record images of the seabed environment in real time. The image acquisition unit provides monitoring personnel with intuitive visual information of the seabed environment, making up for the limitations of sensor data. The high-definition camera can capture clear and detailed seabed images, allowing monitoring personnel to directly observe the seabed topography, biological communities, equipment status, and other conditions. The fill light device provides sufficient lighting in dimly lit seabed environments, ensuring that the camera can capture high-quality images. By recording the seabed environment images in real time, monitoring personnel can promptly detect abnormal conditions on the seabed. The energy supply module includes solar panels, wave power generation devices and energy management systems. The energy supply module is electrically connected to the energy storage battery. Solar panels use solar energy to generate electricity and are a clean and renewable energy source. In sufficient sunlight, solar panels can provide a large amount of electricity for the device, reducing dependence on traditional energy. Wave power generation devices use the energy of ocean waves to generate electricity and can continue to provide power to the device even in the absence of sunlight. The energy management system can intelligently manage and distribute the electricity generated by solar panels and wave power generation devices to ensure efficient use and reasonable storage of electricity.

[0019] Furthermore, the data processing module has a built-in temporal neural network (TNN) algorithm, which is used to extract time series features from historical monitoring data and generate a diffusion trend prediction model for the CO2 storage area in combination with real-time data. The temporal neural network (TNN) algorithm has powerful time series analysis capabilities and can handle complex nonlinear data relationships. By learning and training on a large amount of historical monitoring data, the TNN algorithm can establish an accurate prediction model. The addition of real-time data enables the model to reflect current environmental changes in a timely manner, improving the accuracy and timeliness of the prediction.

[0020] Furthermore, the underwater acoustic communication unit is based on orthogonal frequency division multiplexing (OFDM) technology, adopts 16-QAM modulation, the communication bandwidth covers the 1-10kHz frequency band, and has a built-in multipath equalizer; the underwater acoustic communication unit adopts orthogonal frequency division multiplexing (OFDM) technology and 16-QAM modulation, which greatly improves the bandwidth and transmission rate of underwater communication; the communication bandwidth covers the 1-10kHz frequency band, which can meet the transmission requirements of different data volumes, ensuring that sensor data, image data, etc. can be transmitted quickly and accurately; the built-in multipath equalizer can effectively compensate for the multipath effect in underwater communication, reduce signal distortion and interference, and improve communication reliability.

[0021] The satellite relay unit integrates a low-orbit satellite communication module (supporting Starlink / Beidou short message dual modes), reducing the latency of deep-sea data to shore-based centers; providing strong support for real-time monitoring and decision-making. At the same time, dual-mode support ensures reliable communication in different communication environments, improving the system's adaptability and fault tolerance.

[0022] Example 2 further optimizes the submarine carbon dioxide storage monitoring device provided in Example 1. Specifically, the sensor array further includes a dissolved oxygen sensor and a turbidity sensor for monitoring the dissolved oxygen content and suspended particle concentration of the submarine water, assisting in determining the impact of CO2 leakage on the respiratory environment of marine organisms and water transparency. The addition of the dissolved oxygen sensor and turbidity sensor further enriches the monitoring function of the sensor array, enabling the monitoring device to more comprehensively assess the impact of CO2 leakage on the marine environment. Dissolved oxygen is a substance necessary for the survival of marine life. Changes in its content directly affect the breathing and living environment of marine life. By real-time monitoring of dissolved oxygen content, the impact of CO2 leakage on the breathing environment of marine life can be discovered in a timely manner, providing important early warning information for protecting the marine ecosystem. Turbidity sensors can measure the concentration of suspended particles in seabed water and reflect the transparency of the water. CO2 leakage may cause changes in the geological structure of the seabed, thereby causing an increase in suspended particles and affecting the transparency of the water. By monitoring changes in turbidity, the situation of CO2 leakage can be indirectly judged, providing a basis for taking timely measures.

[0023] Furthermore, the solar panels use flexible cadmium telluride thin film batteries with a thickness of ≤2mm, which can be installed on the curved surface of the cabin; the flexible cadmium telluride thin film batteries use advanced thin film preparation technology, making the batteries light and flexible; cadmium telluride materials have a high photoelectric conversion efficiency and can efficiently convert solar energy into electrical energy.

[0024] Furthermore, the wave energy power generation device adopts a magnetorheological fluid damping oscillation structure, which can capture the energy of weak ocean currents with a flow rate of 0.1-5m / s and broaden the power generation threshold in low flow rate environments; the magnetorheological fluid damping oscillation structure is a new type of energy conversion structure. It uses the rheological properties of magnetorheological fluid and can automatically adjust the damping force according to changes in ocean current velocity, thereby improving energy conversion efficiency.

[0025] Furthermore, it also includes a microbial monitoring unit, which contains a fluorescently labeled probe array for specifically identifying changes in seabed microbial communities caused by CO2 leakage (such as a surge in the number of chemosynthetic bacteria). The probe detection limit is as low as 10³CFU / mL; the fluorescently labeled probe is designed for the 16S rRNA sequence of chemosynthetic bacteria, and the probe surface is modified with Cy5 fluorescent dye. The detection limit is 10³CFU / mL, and the microbial abundance is quantified by the fluorescence signal intensity.

[0026] Furthermore, the communication module integrates blockchain evidence storage, encrypting the monitoring data with hash values ​​and synchronizing them to the alliance chain nodes, ensuring that the data cannot be tampered with and providing a trusted chain of evidence for environmental supervision. Blockchain technology uses a distributed ledger and consensus mechanism to ensure that data cannot be tampered with and is traceable. Hash value encryption is a one-way encryption algorithm that can convert data of any length into a fixed-length hash value, which is unique and irreversible. The synchronous storage of alliance chain nodes is achieved through network protocols and consensus algorithms, ensuring the consistency and reliability of data across multiple nodes. Hash value encryption uses the SHA-256 algorithm, and alliance chain nodes synchronize data based on the PBFT consensus mechanism to ensure that the monitoring data cannot be tampered with.

[0027] Example 3 further optimizes the submarine carbon dioxide storage monitoring device provided in Example 1 or 2. Specifically, the outer shell of the main control cabin is made of a titanium alloy-carbon fiber composite material, and the surface is sprayed with a bionic anti-biological attachment coating. The outer shell of the main control cabin is made of a titanium alloy-carbon fiber composite material, which combines the high strength and corrosion resistance of titanium alloy with the lightweight and high strength characteristics of carbon fiber. This gives the cabin excellent structural strength and corrosion resistance, and enables long-term stable operation in the high-pressure, high-salt, and high-corrosion environment of the deep sea. The bionic anti-biological attachment coating sprayed on the surface imitates the surface structure and characteristics of marine organisms, and can effectively inhibit the attachment of marine organisms such as barnacles and mussels. The attachment of marine organisms will increase the weight and resistance of the device, affecting the normal operation of the device, and may also cause corrosion and damage. By inhibiting biological attachment, the maintenance frequency of the device can be reduced, the maintenance cost and workload can be reduced, and the reliability and service life of the device can be improved. The coating is a polydimethylsiloxane (PDMS)-based material that inhibits the attachment of marine organisms.

[0028] Furthermore, the image acquisition unit is equipped with a multispectral imaging lens that supports multi-band shooting of visible light, infrared light, and ultraviolet light. This allows it to penetrate turbid water areas and clearly capture leaks such as seabed cracks and bubble overflows. The application of the multispectral imaging lens greatly improves the imaging capability of the image acquisition unit in complex seabed environments. The visible light band can provide clear color images for observing the general conditions and biological communities of the seabed. Infrared light has strong penetrating power and can penetrate a certain depth of water even in turbid water to capture hidden information on the seabed, such as cracks and thermal anomalies. The ultraviolet light band can be used to detect the fluorescence characteristics of certain specific substances, which helps to detect chemical leaks and biological activities on the seabed; By supporting multi-band shooting, the image acquisition unit can capture various information on the seabed more comprehensively and accurately, and promptly detect signs of CO2 leakage, such as cracks and bubble overflows. These high-resolution, multi-spectral image data provide monitoring personnel with more detailed and intuitive information, helping to accurately determine the location, scale and trend of the leakage, and providing strong support for timely measures.

[0029] Furthermore, the energy storage battery is a solid-state lithium-sulfur battery with an energy density ≥500Wh / kg and a cycle life ≥3000 times in the temperature range of -20℃~60℃, which can meet the long-term energy storage needs in deep-sea low-temperature environments.
