Dam Safety Monitoring System: Dam Safety Monitoring and Intelligent Operation Management Solution

I. Product Introduction

The dam safety monitoring system is a comprehensive monitoring system used to monitor the operating status of dams and related hydraulic structures, collect engineering safety data, and assist in safety management. It is widely used in reservoir dams, hydropower stations, river closure dams, and other water conservancy and hydropower projects.

By deploying various sensors, data acquisition equipment, communication equipment, and monitoring software, the system continuously or periodically monitors parameters such as deformation, seepage, seepage pressure, stress and strain, and environmental hydrology during dam operation. After the collected data is transmitted, stored, and analyzed, it can be centrally displayed, trend-analyzed, anomaly-alerted, and historically queried on the monitoring platform.

According to the project scale, dam type, and safety monitoring requirements, the system adopts a layered architecture:Front-end sensors → LCU Local acquisition control cabinet → Communication network → Monitoring center SCADA / Digital twin platform, helping management personnel keep abreast of dam operating status and providing data support for engineering safety inspections, operation and maintenance, and risk assessment.

The system can be customized according to project requirements and is suitable for new dam safety monitoring projects, and can also upgrade and renovate existing old monitoring facilities.

II. Core Monitoring Items

l Deformation monitoring: Configure relevant monitoring equipment according to engineering design to collect horizontal displacement, vertical displacement, and other deformation data of the dam body.

l Seepage and seepage pressure monitoring: Monitor parameters such as seepage flow and seepage pressure of the dam body, dam foundation, and related parts to assist in analyzing seepage conditions.

l Stress and strain monitoring: Monitor structural stress, strain, and related temperature parameters as required by the project to provide data for analyzing structural operating status.

l Environmental and hydrological data collection: Can connect to relevant monitoring data such as water level, rainfall, and temperature, and conduct comprehensive analysis in combination with project operation conditions.

l Automatic data collection: Through automated acquisition equipment, obtain monitoring data according to the set collection cycle, reducing manual on-site collection workload.

l Remote data transmission: Support configuring wired or wireless communication methods according to site conditions to upload monitoring data to the central monitoring platform.

l Anomaly alarm: Based on set monitoring thresholds, rate of change, or other judgment rules, provide prompts or alarms for abnormal data.

l Data analysis and trend query: Support historical data storage, curve display, trend comparison, and report query, facilitating long-term monitoring and operation analysis.

l Centralized monitoring management: Centrally view data, equipment status, and alarm information of multiple monitoring points through the monitoring platform, improving engineering monitoring management efficiency.

Specific monitoring items, sampling frequency, alarm rules, and analysis functions are determined according to engineering design and actual configuration.
