Intelligent Comprehensive Safety Monitoring Solution for Water Resources

Background Introduction

The reservoir safety monitoring system comprises intelligent reservoir sensing, IoT-based information and communication, and a cloud-based smart monitoring and management platform. For small reservoirs, the online monitoring function enables automatic collection, analysis, and reporting of operational data such as reservoir water level, rainfall, video feeds, seepage flow, and seepage pressure. The self-organizing network and IoT system provide comprehensive multi-parameter data acquisition and communication capabilities, while the cloud platform of the reservoir safety monitoring and early-warning system offers intelligent analysis and alerting for monitoring data. Together, these components deliver end-to-end support for remote perception of reservoir operating conditions, operational trend analysis, safety management, and online management of inspection and patrol activities, thereby supporting both individual reservoir management and large-scale management across provinces, cities, or counties.

Solution Overview

The water resources safety monitoring and early warning system encompasses a wide range of monitoring sensors, including GNSS, rain gauges, radar-based water level gauges, video surveillance cameras, GNSS, flume flow meters, and vibrating-wire piezometers, to enable the automated acquisition, transmission, storage, processing, and analysis of water resources safety monitoring data. When monitored data exceed predefined alert thresholds, the system promptly issues early warning notifications and initiates timely response measures.

FEATURES OF THE SOLUTION

Remote Automatic Monitoring

Implement 24/7 round-the-clock remote automated monitoring

Establish a Unified Identity for Reservoir Management

Establish a unified identity system for reservoir management—“one code per reservoir, one code per station”—by affixing QR codes to all reservoir monitoring devices and information display boards, enabling users to access relevant reservoir information by scanning the codes.

AI Intelligent Monitoring

An AI-powered intelligent monitoring and sensing network supports the smart supervision and operation & maintenance of reservoirs, standardizes O&M oversight, and enhances the safe operation of reservoirs.

Scene Visualization

BIM technology is employed to construct a three-dimensional model of the dam, which is integrated with GIS technology to enable 3D visualization. Furthermore, dam safety monitoring data are visualized to support scene browsing and interactive operations, data query and analysis, as well as the provision of dam safety information and early warning services.

Intelligent Monitoring

Intelligent early warning enables the automatic acquisition, transmission, and real-time delivery of data on reservoir dam seepage pressure, seepage flow, strain, water level, temperature, and rainfall around the reservoir. When monitored parameters exceed preset alert thresholds, the system will issue an alarm notification.

Highly integrated platform system

It integrates functions such as dam safety monitoring, rainfall and water-level monitoring, flood forecasting, reservoir operation and dispatch, early warning, and property service management.

Reliable and secure communication

Supports IoT sensors, data acquisition terminals, transmission and communication equipment, and early-warning devices that feature full-network coverage, high reliability, and high security across 5G, 4G, LoRa, GPS/BeiDou, and other networks.

Low power consumption

Wide range of application scenarios: The system monitoring equipment features a low-power design and can be powered by a combination of solar energy and batteries, making it suitable for deployment in remote, rugged outdoor environments.

Reservoir Standard Management and Maintenance System

The reservoir standard management and maintenance system leverages audio, image, and video files to enable real-time, latency-free video calls between the platform and mobile devices, establishing a seamless, real-time link between hazard locations and on-site personnel. This strengthens the seamless integration of human oversight and technological safeguards, addressing the current gap where technological safeguards are robust but human oversight remains underdigitized, and ensuring effective last-mile early warning and response.

Rainfall Monitoring System

The integrated rainwater video monitoring station primarily comprises rainfall monitoring in the reservoir area, reservoir water-level monitoring, AI-powered video surveillance, early-warning broadcasting, and a power-supply system. By leveraging various intelligent sensing devices, it enables dynamic monitoring and real-time data collection of rainfall amounts, reservoir water levels, and regional intrusion detection and alerts, thereby achieving 24/7 remote automated monitoring and early warning.

Dam Safety Monitoring System

The main construction components of the dam safety monitoring system include the installation of automated monitoring instruments and equipment, such as deformation benchmarks/GNSS-based dam displacement monitoring stations, piezometers (seepage pressure transducers), and weirs for flow measurement, to enable 24-hour online data monitoring of dam deformation, seepage pressure and seepage flow, phreatic line elevation, and seepage discharge.

Deformation Monitoring

Typically, manual observations are conducted using installed observation piers; however, GNSS-based automated surface-deformation monitoring may also be employed as appropriate. Alternatively, GNSS automated monitoring equipment can be concurrently installed in addition to manual observations, with automation serving as the primary method and manual observation as a supplementary measure, enabling comparative analysis of the monitoring data to enhance efficiency and reliability.

Platform Display

The reservoir safety monitoring platform comprises modules for site management, real-time monitoring, image-based monitoring, early-warning management, information management, operation and maintenance inspections, statistical analysis, hazard-point management, and system management.

Geodetic GNSS receiver

The geodetic GNSS receiver is a versatile deformation-monitoring device that integrates a high‑precision GNSS module with MEMS sensors. It supports multi‑system, multi‑frequency signal reception, including BeiDou‑3, GPS, and GLONASS, and delivers millimeter‑level static monitoring as well as centimeter‑level dynamic monitoring.
