备注

为全面提升地震应急指挥能力和协同应急通讯效率,天津市地震局应急指挥大厅基于跨网段多层级视频融合技术完善天津市地震应急视频指挥调度网络,构建“平战结合”双模式。通过探究跨网段通讯、多层级音视频信号转发、多点控制单元(MCU)级联等技术,实现天津局与中国局、市政府、市应急管理局以及辖区内各应急视频节点互连互通,为天津市地震应急快速响应提供高效的通信保障。
To enhance the capability of earthquake emergency command and the efficiency of multi-point coordina‐tion emergency communication,the emergency command hall of Tianjin Earthquake Agency improves the Tianjin earthquake emergency video command and dispatch network based on cross-network multi-layer video fusion tech‐nology,and builds the dual mode "combining both daily and emergency". By exploring technologies such as cross-network communication, multi-layer audio-video forwarding technology, and Multi-point Control Units(MCU), the interconnection between Tianjin Earthquake Agency, China Earthquake Administration, Tianjin Municipal People’s Government,Bureau of Emergency Management of Tianjin and various emergency video nodes in the ju‐risdiction is realized,which provides efficient communication guarantee for the rapid response of earthquake emer‐gency in Tianjin
