Overview:
In recent years,frequent geological disasters caused by long-term groundwater impacts(e.g.,subsidence funnels,land subsidence,ground fissures,karst collapses,seawater intrusion,and water quality pollution)have highlighted the urgent need to improve the comprehensiveness and accuracy of groundwater monitoring.While groundwater monitoring has developed alongside socio-economic progress,evolving global climate conditions and water resource challenges demand new solutions.Establishing a long-term groundwater monitoring network,enhancing automated monitoring capabilities,strengthening information services,and advancing applied research are essential for scientifically protecting groundwater resources,ensuring sustainable utilization,and supporting socio-economic development.
System Structure:
The system consists of front-end monitoring devices and a central monitoring platform.Data communication between front-end devices and the central platform is achieved via 3G/4G/5G wireless transmission to the central server room over the public internet.
Front-End Devices:
Integrated water level gauges with built-in lithium batteries,compact in size and suitable for deployment in remote field locations.
Monitoring stations require no dedicated buildings;only PVC/galvanized pipe monitoring wells are pre-installed,protected by outdoor equipment boxes.
Water Level Measurement Principle:
Based on hydrostatic pressure principles,where pressure correlates with water depth.Pressure-sensitive integrated sensors measure the water column pressure at fixed underwater points,enabling indirect water level calculation by adding the point’s elevation.
System Functions:
Automatic Data Collection:
Accurately and reliably captures real-time groundwater level,flow,quality,and temperature data.
Proactive Alarm Reporting:
Automatically alerts the monitoring center for on-site anomalies(e.g.,unauthorized cabinet access,power failure,device malfunctions).
Metering Device Monitoring:
Remotely tracks metering point operations,identifies faults,and detects abnormal metering.
Statistical Analysis:
Supports daily,weekly,monthly,and annual reports with charts(curves,histograms)to visualize monitoring station data.
Cost-Effective Networking:
Flexible communication interfaces allow users to choose economical network solutions,minimizing installation and maintenance costs.
High Reliability:
Hardware and software feature robust anti-interference capabilities,ensuring uninterrupted operation and automatic recovery from faults.
Open Database Design:
Supports user-defined expansion of monitoring stations and sensors.
Real-Time Dispatch Updates:
Leverages advanced IT and communication technologies to share groundwater monitoring data and dispatching information with data distribution centers,enabling public resource integration.
