Core Insights - The article discusses the implementation and effectiveness of the urban lifeline safety monitoring system in Hefei, which utilizes advanced technologies to ensure the safety of critical infrastructure such as bridges, gas, water, and electricity networks [2][4]. Group 1: System Implementation and Functionality - The Hefei Urban Lifeline Safety Monitoring Center has a sophisticated alert system that triggers warnings for issues like bridge overloads and gas leaks, allowing for rapid response [1][2]. - Since 2015, Hefei has partnered with Tsinghua University to develop a comprehensive safety monitoring system that integrates IoT, cloud computing, and big data [2][3]. - The monitoring system has installed approximately 85,000 sensing devices across various infrastructures, covering 137 bridges and 7,316 kilometers of pipelines [3]. Group 2: Performance Metrics - The average response time for various alerts has improved to 7 minutes, with joint response times reduced from over 24 hours to 1 hour [2][3]. - The system has issued numerous alerts, including 562 gas leak warnings and 167 water leak warnings, all of which have been successfully addressed [3]. - The efficiency of risk detection has increased by approximately 70%, while the accident rate has decreased by about 60% since the system's implementation [3]. Group 3: Future Prospects - The urban lifeline project initiated in Hefei has expanded to over 70 cities across the country, indicating its successful model for urban safety management [4]. - Tsinghua Hefei Institute aims to continue integrating public safety technology with industry innovation to enhance smart societal governance [4].
