In recent years, frequent extreme weather events and aging hydraulic infrastructure have led to increasing safety risks in dam structures.The traditional manual monitoring methods are limited by poor timing, fragmented information, and delayed alerts. They do not meet the modern management needs. This solution uses a collaborative architecture that integrates multi-source sensors, intelligent communication networks and cloud-based analytical platforms to create a real-time whole-process monitoring system. It improves emergency response and dam health assessment capabilities, moving towards the goal of "digital water conservation."
Integrated Rainfall & Water Level Station
Function: Monitors reservoir water levels and rainfall in real time. Triggers tiered alerts upon detecting anomalies and broadcasts warnings to neighboring stations via a self-organizing LoRa-MESH network.
Visual-Audio Broadcast Station
Function: Deploys an "integrated visual-audio surveillance network" for remote video retrieval and localized emergency broadcasting via onboard speakers.
Seepage Pressure & Flow Monitoring Station
Function: Evaluates dam stability by analyzing seepage pressure, flow rate, and displacement data. Provides early warnings for risks such as piping and landslides.
Transmission & Platform Layer
Multi-Source Sensing Synergy
Integrates multi-dimensional data (water level, rainfall, seepage pressure, displacement, video) for cross-validation and comprehensive analysis, improving warning accuracy.
Automatically retrieves video feeds from corresponding zones when seepage anomalies are detected, aiding manual verification.
High-Reliability Communication & Edge Computing
Smart terminals support data resumption and local storage, ensuring cached data is retransmitted after communication restoration.
Edge-side embedded algorithms (Kalman filtering, abrupt change detection) eliminate sensor noise in real time, reducing false alarms.
Intelligent Tiered Alerting
Three-level thresholds (Notice, Warning, Critical) trigger synchronized local alarms (audio-visual), platform pop-ups, and SMS notifications.
Customizable alert logic to adapt to risk management needs of different reservoirs.
Environmental Adaptability & Low-Power Design
IP68-rated enclosures and operating temperatures from -40°C to 85°C ensure functionality in harsh conditions (humidity, dust, extreme heat).
Solar + lithium battery power enables 30-day continuous operation under rainy conditions, minimizing maintenance frequency.
