走进实验室｜在海底装上“千里眼”“顺风耳”

Core Insights - The establishment of the Jiangsu Undersea Communication and Sensing Key Laboratory aims to develop the "Undersea Information Superhighway" and explore intelligent observation networks in the deep sea, aligning with national strategies for marine power and information security [1][2]. Group 1: Undersea Communication Technology - Global data traffic is increasing exponentially, with over 95% of data transmitted via undersea cables, leading to a capacity crisis in marine communication [2]. - Spatial Division Multiplexing (SDM) technology is recognized as the future direction for undersea communication, enhancing data transmission capacity by creating multiple channels within a single cable [2]. - The laboratory is advancing three generations of SDM technology, aiming to significantly increase transmission rates and system capacity [3]. Group 2: Intelligent Observation Systems - The laboratory is focused on building a comprehensive sensing system for both shallow and deep seas, which is crucial for marine power development [4]. - The undersea sensing technology integrates communication cables with sensors, allowing for real-time monitoring of ocean conditions [5]. - The laboratory aims to create a collaborative observation system that provides critical data for climate change monitoring and disaster early warning [6]. Group 3: Data Processing and Analysis - The undersea sensing system generates vast amounts of data, comparable to the information in a medium-sized library, which requires effective processing to be useful [7]. - The laboratory employs edge computing to enhance data quality through cleaning, formatting, and preliminary analysis, improving efficiency by 40% [7]. - Collaboration with China Ocean University enables the development of intelligent algorithms for rapid processing of marine data, supporting timely decision-making for environmental monitoring and resource development [7]. Group 4: Future Development Goals - The laboratory plans to establish a high-level academic platform and innovative talent teams over the next three years, aiming to achieve breakthroughs in key technologies and set international standards [8].
