China's AI-powered 'flying lifebuoy' joins water rescue toolkit_我的网站
A | 搬家到拱墅区永兴坊的第三年，刘先生忽然发现楼道变了样：纠缠多年的通信线缆消失不见，墙面清爽整洁了不少。

According to a report posted on the official WeChat account of Hangzhou, an orange lifebuoy took off from the shore during the drill, flew toward a person who had fallen into the water, and landed on the water surface. Even when the person climbed onto it, the device remained stable and continued to float.
Minutes later, rescuers arrived and brought the person to safety. The lifebuoy then took off again and returned to its original location.
The device, officially called an AI intelligent flying rescue robot, is designed to provide rapid assistance in open waters where rescue boats may take time to arrive. Equipped with an autonomous navigation system, it can fly to people in distress, provide buoyancy support, and return automatically after completing its mission.
The drill featured multiple water rescue scenarios and tested several intelligent rescue technologies. Drones were used to drop inflatable lifebuoys above people in distress, which quickly inflate upon hitting the water to provide temporary buoyancy.
Another system combined an unmanned boat and drone for rescue operations in dangerous waters. The drone searches and locates people in need, while the boat navigates autonomously to assist the rescue. The drone can also provide lighting for nighttime searches, according to the report.
Chinese Foreign Ministry spokesperson Lin Jian highlighted in a social media post on August 14 that the AI-powered device is "technology that could help save lives."

。更让他意外的是，儿子想换宽带，不必再穿墙打洞破坏家中原有装修——光纤已提前接入家里的弱电箱，打个客服电话就能开通。“以前装宽带，电信拉一根、移动拉一根，楼道里跟缠满了蜘蛛网似的。”刘先生感慨道，“改造后，不仅楼道环境大变样，选宽带也更自由了。”刘先生所在小区的喜人变化，源于杭州“多网合一”驻地网模式的落地推进。记者从市城建发展集团下属杭州市地下管道开发有限公司（以下简称“管道公司”）获悉，截至目前，这一模式已覆盖全市400多个小区，惠及约36万户居民。管道公司相关负责人介绍：“‘多网合一’驻地网模式的核心，是由管道公司统一建设共享机房和集约化管线，各运营商利用该集约网络平台接入小区住户。居民可自由选择心仪的运营商。运营商更迭也无需重新穿墙布线，从源头避免了重复施工对居民生活的反复干扰。”带来的改变远不止使用便利。通过统一建设、统一运维，从源头根治了老旧小区空中“蜘蛛网”和楼道线缆乱拉的老大难问题——改造前，不少小区楼道内管线纵横密布，既影响居住环境，也暗藏安全隐患；改造后，线缆全部入管入槽，墙面恢复整洁，安全隐患也随之消除。多家运营商共用集约网络平台，还避免了重复投资，大幅节约了基建投入和后期维护成本。“多网合一”驻地网模式是管道公司地下通信管网集约化建设向用户端延伸的“最后一公里”。这一模式最早在部分新建小区试点，随后在老旧小区改造过程中逐步推开。
