Description

Technical Field

[0001] The present invention relates to the technical field of data acquisition, and in particular to an underwater platform data acquisition and transmission system. Background Art

[0002] With the development of underwater communication and ocean exploration technologies, the demand for data collection and transmission from underwater platforms is increasing. However, due to the complexity of the underwater environment, traditional data collection and transmission methods often fail to meet the requirements for efficient and stable communication when faced with problems such as high attenuation, multipath effects, time-varying channel characteristics, and limited bandwidth.

[0003] Currently, traditional underwater data transmission systems rely primarily on underwater acoustic communication technology, which focuses on fixed channel modeling, traditional Bayesian channel estimation, and signal optimization methods based on fixed rules. However, in complex underwater environments, existing technologies have significant shortcomings in the following aspects: 1. Low channel estimation accuracy: Existing underwater communication systems mostly use classical Bayesian methods or statistical channel modeling for channel estimation, which cannot effectively cope with the rapid changes of underwater channels, resulting in large channel state prediction errors and affecting the stability of data transmission.

[0004] 2. Weak multipath interference suppression capability: Underwater channels have strong multipath effects. Traditional underwater acoustic communication systems find it difficult to effectively distinguish between direct path signals and multipath reflection signals, resulting in severe signal interference and affecting data reception quality.

[0005] 3. Insufficient data fusion capabilities: Existing technologies mostly rely on a single type of signal for data transmission, making it difficult to achieve multimodal information fusion, especially in the optimization matching and joint transmission between underwater acoustic signals and quantum state signals, and lack effective feature fusion methods.

[0006] 4. Lagging channel optimization methods: Traditional underwater acoustic channel optimization methods usually rely on preset rules or static optimization strategies, which are difficult to dynamically adjust according to real-time changes in the underwater environment. This results in poor system adaptability and inability to efficiently optimize channel characteristics.

[0007] 5. Low energy management efficiency: Existing underwater data acquisition and transmission systems lack optimization strategies for low-power operation. Especially in long-distance ocean exploration missions, the energy management mechanism for long-term operation of equipment is imperfect, making it difficult to effectively improve the system's endurance.

[0008] 6. Insufficient data security: Traditional underwater acoustic communication systems are easily affected by environmental noise and external interference, and lack physical-level encryption mechanisms for information security protection. They are vulnerable to eavesdropping and attacks, and cannot meet the needs of high-security data transmission.

Based on the channel characteristic adjustment vector and the characteristic mapping matrix, the channel adaptive weight matrix is dynamically adjusted to optimize channel characteristics and improve signal stability. The optimized channel characteristic matrix is used for weighted fusion of underwater acoustic signals and quantum state signals to generate a fused signal matrix, ensuring the robustness and anti-interference capability of data transmission. Based on the fused signal matrix, the channel adaptive transmission characteristics are extracted, the optimized transmission parameters are calculated, and these parameters are input into the data transmission optimization module to achieve efficient and low-bit-error-rate underwater data transmission. Through the joint optimization of channel optimization and signal fusion, this method improves the reliability, anti-interference capability, and adaptive transmission capability of underwater signals, enabling the system to achieve stable and low-power data transmission in complex underwater environments.

[0047] Example 1: In order to verify the feasibility of the present invention in practice, the present invention was applied to a deep-sea exploration project of a certain ocean research center. The underwater platform data acquisition and transmission system proposed in the present invention was used to conduct long-term monitoring and data transmission of the deep-sea environment. The project deployed a series of underwater sensor nodes and data relay stations to obtain deep-sea environmental parameters, including temperature, salinity, pressure, flow rate, and underwater biological signals. However, existing underwater communication systems face significant challenges in this environment, such as severe channel attenuation, strong multipath effects, low data transmission rates, and significant signal interference. These challenges result in unstable data transmission and high packet loss rates, affecting the continuity and reliability of deep-sea observation missions.

[0048] In this scenario, the underwater platform data acquisition and transmission system of the present invention is deployed between multiple deep-sea data acquisition nodes and relay stations to optimize data transmission paths and improve the stability of underwater acoustic communications. The system uses an underwater acoustic-quantum joint feature matching network, combining feature mapping of quantum state signals and underwater acoustic signals to achieve channel optimization and data fusion. Specifically, after the underwater sensor nodes collect environmental data, they transmit it through the underwater acoustic channel. The quantum measurement unit obtains channel state information in real time and combines sparse Bayesian modeling to perform channel prediction. At the receiving end, the system extracts the features of the underwater acoustic signal and the quantum state signal, and performs signal fusion through a joint feature matching network. The channel weights are dynamically adjusted to optimize channel characteristics and improve the stability and anti-interference capability of data transmission.

[0049] In actual application, this system uses multiple underwater sensing nodes to collect data at 5-minute intervals. The data is transmitted via underwater channels to a buoy station and a submarine relay station, and then to a ground-based data center. During data transmission, the channel optimization method of the present invention is used to perform real-time channel state assessment and adaptive adjustment to reduce multipath interference and signal attenuation. Experimental data compares the performance of a traditional underwater acoustic communication system with the system of the present invention in key indicators such as data transmission reliability, packet loss rate, channel estimation error, and energy consumption. The experimental results are shown in the table below.

[0050] Table 1 Performance comparison between traditional underwater acoustic communication system and the system of the present invention

[0051] It can be seen from the experimental data that the underwater data acquisition and transmission system of the present invention has significant improvements in many key indicators compared to traditional underwater acoustic communication systems. The average data transmission rate has increased from 2.4 kbps to 5.8 kbps, an increase of 141.7%; the data packet loss rate has been reduced to 5.6%, a reduction of 69.7% compared to traditional systems. The channel estimation error has been reduced to 3.9%, which has improved the accuracy of channel state prediction and effectively optimized the data transmission path. At the same time, the bit error rate has been reduced to 4.1%, which has significantly improved the data integrity at the receiving end. In addition, the energy consumption has been reduced to 0.67 J / KB, which has improved the endurance of underwater equipment and made the system suitable for long-term ocean observation missions.

[0052] During implementation, the system also conducted channel optimization tests for extreme underwater environments. For example, in the area of ocean hydrothermal vents, due to the dramatic changes in water flow, the data transmission rate of traditional underwater acoustic communication systems fluctuates greatly. However, through quantum measurement and adaptive channel optimization, this system improves the data transmission stability index from 65.4 to 92.8, effectively reducing the impact of environmental interference on data transmission. Furthermore, in deep sea areas below 4,000 meters, where water pressure and temperature changes affect channel attenuation characteristics, this system can dynamically adjust the signal modulation strategy based on channel feedback information, reducing the bit error rate of data transmission by 73.2%, ensuring the reliability of long-distance underwater communications.

[0053] In summary, the underwater platform data acquisition and transmission system of the present invention improves the stability, reliability and energy efficiency of data transmission through the underwater acoustic-quantum joint feature matching network and adaptive channel optimization technology, significantly reduces the data loss rate and bit error rate, and optimizes energy consumption, providing an efficient and low-energy solution for deep-sea observation, marine resource exploration and underwater communication.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
