AI Technical Summary
Technical Problem
Existing ship distress and rescue systems suffer from long overboard warning response times, resulting in insufficient timeliness and rapid response capabilities.
Method used
Uplink signal strength detection function was added to the shipborne 5G base station, and a water-falling alarm APP was added to the 5G terminal side. By utilizing the low latency and high bandwidth characteristics of the 5G network, rapid water-falling detection was achieved through software upgrades, and alarm information was sent in conjunction with the Beidou positioning system.
Benefits of technology
It significantly shortens the response time for drowning alarms from the current 3 minutes to less than 10 seconds, improving rescue efficiency.

Abstract
本发明提供了一种5G信号的落水检测方法及系统，属于无线通信领域，方法包括：将目标用户的SIM卡的IMSI信息配置给舰载5G基站；若实际接入用户为目标用户，对舰载5G基站配置上行参考信号，将SRS检测接收强度实时上报至告警服务器；若设定检测周期内下行广播信道接收强度的下降幅度超过门限值，并且其绝对值低于门限值，告警服务器接收落水告警信息以及5G终端北斗定位信息。开启上行信号检测窗口后读取上行信号强度；如果上行信号强度与上一个周期读取的上行信号强度的下降超过门限，且其绝对值低于门限，将落水告警信息与5G终端北斗定位信息上报至舰载救生系统。本发明大幅提升了当前遇险救生系统的运行效率。
