As a critical infrastructure for regional flooding prevention, drought mitigation and agricultural irrigation, smaller reservoirs face many challenges, including outdated monitoring methods and data fragmentation. The traditional manual inspection methods are unable to keep up with the real-time monitoring requirements during severe weather conditions, resulting in delayed detection of safety risks such as water levels exceeding flood season limits and spillway obstructions.
This solution integrates dual-channel communications, intelligent sensing devices and a cloud management platform to create a highly reliable, all-weather video rain and water level monitoring system. It facilitates digital transformation in reservoir management, and improves flood prevention and response capabilities.
BGT Hydromet's Rainfall Monitoring Station is mainly composed of reservoir rainfall monitoring, reservoir water level monitoring, AI video monitoring, early warning broadcast and power supply system, using various intelligent sensing equipment, dynamic monitoring and real-time collection of precipitation involved in the reservoir, reservoir water level monitoring information, regional intrusion detection and early warning. Achieve 7*24 hours of remote automatic monitoring and early warning.
Precipitation monitoring: The precipitation monitoring point of the automatic measurement and reporting method, using a tipping bucket rain gauge, the resolution is less than 0.5mm;
Reservoir water level monitoring: the automatic monitoring point of the reservoir water level uses a pressure type water level meter, with a comprehensive accuracy of ±0.1%F•S;
Early warning broadcast: Configure two high-pitched horn speakers to achieve multi-scene automatic voice alarm and remote Shouting functions such as heavy rainfall, high water level, personnel intrusion. The automatic voice alarm should have the function of on-site manual intervention to close;
AI video surveillance: Support area intrusion detection, cross-border detection, entering the area detection and leaving the area intelligent detection alarm;
Display terminal: outdoor full-color LED screen local data display reservoir rainfall, reservoir water level, storage capacity, etc.
Communication mode: Support 4G/5G/ public network transmission;
Power supply system: It has dual power supply of mains and solar energy to cope with complex environment.
