Core Viewpoint - The article discusses the advancements in earthquake rescue technology, emphasizing the importance of various technological tools that enhance rescue efficiency and the development trends towards portability, integration, and intelligence in rescue equipment [1]. Group 1: Life Detection Technologies - Life detection methods during rescue operations include video, audio, and radar technologies, which are essential for locating survivors in rubble [2]. - Video life detectors, known as "snake eyes," can penetrate tight spaces and often include features like illumination and infrared capabilities [2]. - Audio detectors capture sound waves to identify life signs, while radar detectors use electromagnetic waves to detect life signs through non-metallic obstacles, with advancements leading to the use of two-dimensional radar for better visualization [2]. Group 2: Demolition and Support Equipment - The primary danger during earthquakes is the collapse of buildings, necessitating the use of demolition equipment to create rescue pathways [3]. - Large demolition tools include bulldozers and excavators, while smaller tools like hydraulic cutters and impact hammers are used for precise tasks [3]. - The future of demolition tools is focused on being small, lightweight, and high-powered, with additional support tools like jacks and inflatable airbags being used to stabilize rescue pathways [3]. Group 3: Communication and Positioning Technologies - Earthquakes often disrupt communication infrastructure, creating "information islands" that hinder rescue efforts [4]. - Restoring communication is a priority for rescue teams, utilizing local radio systems and satellite phones for long-distance communication [5]. - Advanced technologies like portable base stations and drones are being employed to enhance signal coverage and improve rescue efficiency [5]. Group 4: Intelligent Equipment - The use of intelligent equipment, such as four-legged robots and drones, is becoming a key trend in earthquake rescue, allowing for efficient search and delivery of supplies [6]. - Robots are being developed to mimic human movement and perform tasks in hazardous environments, significantly reducing the physical burden on human rescuers [6]. - The rapid development of embodied intelligence technology is expected to expand the application scenarios for robots in earthquake rescue operations [6].
