Flash Flood Disaster Monitoring and Early Warning System Solution
The flash flood disaster monitoring and early warning system consists of four components: water level gauges, rain gauges, video surveillance, and audible/visual alarms. After collecting data, the hydrological intelligent measurement and control terminal monitors and analyzes the data to determine warning levels, target recipients, and other warning information. Warnings can be issued via multiple channels such as phone calls and SMS. Field data and warning information are remotely transmitted to the monitoring and early warning platform via 4G/NB-IoT wireless networks or the BeiDou satellite system. The platform stores and displays the data.

Solution Details
Policy Background for Flash Flood Disaster Monitoring
In 2021, the Ministry of Water Resources issued the "Implementation Plan for the National Flash Flood Disaster Prevention Project (2021-2023)". The plan aims to comprehensively enhance China's flash flood disaster prevention capabilities through scientific planning, integrated management, and systematic construction, providing strong support for building a safe and harmonious social environment. The plan clarifies the main tasks and priorities of flash flood disaster prevention work, emphasizing adaptation to local conditions and categorized guidance to ensure the scientific validity and operability of all prevention measures.

需求调研与风险普查
摸排山洪易发流域的地形、地质、水文特征，明确监测重点区域；对接水利、应急、气象部门，确定监测要素（雨量、水位等）、预警等级及信息触达要求；开展历史山洪灾害数据收集，为预警模型参数设置提供依据。
方案设计与点位规划
设计 “感知 - 传输 - 平台 - 预警” 四级系统架构；按 “重点区域加密、一般区域覆盖” 原则规划监测点位，优先布设于沟谷口、居民点上游等关键位置；选型高防护、抗冲击的监测设备，确定卫星 / 4G/LoRa 混合通信及三重供电方案；编制实施方案。
设备部署与基建施工
汛期前完成设备安装，包括雨量计、水位计、视频摄像头的立杆架设，太阳能供电系统部署；山区点位加装防冲刷、防泥石流的设备防护装置；搭建通信网络，调试卫星通信模块与本地网关，确保数据传输链路畅通。
平台搭建与模型配置
部署监测预警平台，搭建 GIS 可视化系统，录入流域与村落分布数据；配置山洪预警模型参数，结合本地水文规律设定雨量、水位预警阈值；开发多渠道预警推送功能（短信、喇叭、APP），对接县级防汛指挥平台。
系统联调与功能测试
打通设备与平台的数据链路，测试数据采集、传输的实时性与稳定性；模拟山洪灾害场景，验证预警模型触发逻辑与分级推送效果；测试应急通信中继功能，确保基站损毁时数据不中断。
竣工验收与交付
由多部门联合验收系统功能、设备稳定性及预警响应效率；移交技术资料与运维手册；建立运维台账，明确设备巡检、故障处置的责任主体。
