隧道“夜行者”用科技照亮旅途

Core Viewpoint - The article highlights the efforts of a youth inspection team from the China Railway Beijing Group to ensure the safety and reliability of the Tianjin underground diameter line during the busy Spring Festival travel period, utilizing advanced technology for efficient inspections [2][4]. Group 1: Inspection Operations - The Tianjin underground diameter line is a crucial hub connecting multiple high-speed rail lines, and its power supply stability is vital for train safety and passenger experience during the Spring Festival [2]. - The inspection team operates during the "window period" when trains are not running, conducting nearly four hours of inspections in freezing conditions [2][3]. - The team performs a 5-kilometer walk-through inspection in a cold, dark environment, where temperatures drop below zero degrees Celsius [3]. Group 2: Technology Utilization - The inspection team employs an intelligent dynamic parameter detection device that uses high-definition cameras and sensors to monitor key parameters of the contact network, achieving three times the efficiency of traditional manual inspections [4]. - A drone equipped with high-definition cameras and infrared thermal imaging is used for comprehensive inspections of hard-to-reach areas, significantly reducing inspection time from two hours to just ten minutes for 1,000 meters of track [4][5]. - Infrared thermometers are utilized to measure the temperature of critical electrical equipment, with a focus on preventing failures by identifying overheating issues [5]. Group 3: Safety and Maintenance - The inspection team identifies and addresses safety hazards, ensuring that the power supply system remains reliable and efficient for train operations [5]. - Each identified hazard is documented to ensure accountability and thorough communication among team members, aiming for comprehensive safety management [5]. - The team balances day-time administrative tasks with night-time inspections, demonstrating commitment to passenger safety during peak travel times [5].
