现代科技助力古老长城“延年益寿”

Core Viewpoint - The integration of advanced technology, including AI and robotics, is enhancing the efficiency and effectiveness of the preservation and inspection of the Great Wall, particularly in the Shanhaiguan area, showcasing a shift towards intelligent and data-driven conservation methods [1][2][5]. Group 1: Technological Innovations - A quadruped robot equipped with smart sensors, high-definition cameras, and laser radars is being used for inspections of the Great Wall, capable of identifying surface cracks and missing bricks [1]. - The robot conducts inspections in approximately 30 minutes and generates reports for timely repairs, significantly improving inspection efficiency and quality [1]. - The use of distributed fiber optic sensors allows for real-time monitoring of structural changes in the Great Wall, providing early warnings for potential damage [2]. Group 2: Environmental Protection Techniques - The application of filamentous blue-green algae acts as a natural protective layer for the Great Wall, enhancing its resistance to rain and wind erosion [2][4]. - Specific microbial activities can fill cracks and strengthen the soil structure, improving the durability of the brick wall against weathering [4]. Group 3: Funding and Project Implementation - Since 2019, over 77 million yuan has been invested in the preservation of the Great Wall in Shanhaiguan, with multiple key projects completed to enhance preventive technological protection [5]. - In 2023, an additional budget of 29.29 million yuan is allocated for the protection of the North Wing City site, aiming to transition from traditional preservation methods to modern data-driven approaches [5].
