Non-Contact Monitoring for Existing Buildings and Urban Structures
Reliable Structural Monitoring. Smarter Building Safety.
Hu Entropy Tech provides an integrated structural health monitoring solution for existing buildings, aging structures, and urban infrastructure. Combining advanced vision-based displacement measurement, passive optical targets, multi-sensor data acquisition, and cloud-based monitoring, the solution enables continuous, remote monitoring of structural behavior without direct physical contact with the monitored structure.
The system helps engineers identify potential structural changes, assess deformation trends, and detect abnormal movements at an early stage, providing reliable data for building safety assessment and risk management.
Key Monitoring Parameters:
Building Tilt | Differential Settlement | Structural Deflection | Crack Opening | Curtain Wall Displacement
1. Non-Contact Vision-Based Monitoring
Advanced Optical Measurement for Structural Displacement
Based on oblique-axis imaging and Digital Image Correlation (DIC) technology, the Online Visual Tracking System uses high-resolution imaging and sub-pixel target tracking algorithms to measure two-dimensional displacement at multiple monitoring points.
Passive optical targets are installed at selected locations on façades, beams, slabs, curtain walls, and other critical structural components. The monitoring system continuously captures images, identifies target positions, and calculates horizontal and vertical displacement without requiring direct contact with the monitored structure.
Measurement data can be transmitted to the cloud platform for real-time visualization, trend analysis, and automated alerts, supporting long-term structural monitoring and safety evaluation.
2. Key Features & Advantages
Remote Non-Contact Monitoring
Measure structural displacement remotely without physical contact with the monitored components, minimizing interference with building operations.
Multi-Point Measurement
Monitor multiple structural points simultaneously, providing a comprehensive view of building deformation and movement.
Sub-Millimeter Measurement Capability
Deliver high-resolution displacement measurements with sub-millimeter accuracy under suitable installation and environmental conditions.
24/7 Continuous Monitoring
Support automated, long-term monitoring with minimal manual intervention, enabling continuous observation of structural behavior.
Intelligent Alarm Notifications
Configure multi-level alarm thresholds to identify abnormal displacement and provide timely notifications for potential structural risks.
Multi-Sensor Integration
Integrate vision-based monitoring with conventional sensors, including settlement, tilt, strain, vibration, and crack monitoring devices, for comprehensive structural data acquisition.
3. Monitoring System Architecture
Integrated Sensing, Data Acquisition, and Cloud Management
Visual Sensing → Data Acquisition → Wireless / Wired Communication → Cloud Platform → Analysis & Early Warning
The integrated monitoring architecture combines vision-based displacement measurement, multi-channel data acquisition units, RTU communication devices, and centralized cloud management.
The system supports 4G/5G and Ethernet communication, enabling remote data transmission, real-time monitoring dashboards, historical trend analysis, report generation, and API-based data integration.
Flexible deployment options allow the system to be adapted to different building structures, monitoring requirements, and project scales.
4. Typical Applications
Existing & Aging Buildings
Monitor long-term building tilt, differential settlement, and structural deformation to support routine safety assessments and maintenance planning.
Damaged or High-Risk Buildings
Enable remote, non-contact structural monitoring in potentially hazardous areas, reducing the need for personnel to access unsafe locations.
Construction Impact Monitoring
Track structural settlement, tilt, displacement, and crack development caused by nearby excavation, tunneling, piling, and other construction activities.
Historic & Heritage Buildings
Provide low-disturbance structural monitoring using minimally invasive and reversible target installation methods, helping preserve sensitive architectural structures.
Curtain Wall & Façade Monitoring
Monitor displacement and deformation of curtain walls, façade panels, and other external building components to identify abnormal movement.
Large-Span Buildings
Monitor structural deflection and deformation in stadiums, exhibition centers, railway stations, airport terminals, and large-span roof structures.
5. A Smarter Approach to Building Safety
From individual structural components to entire building complexes, Hu Entropy Tech combines intelligent visual measurement, multi-sensor integration, and cloud-based data management to provide a flexible and scalable structural health monitoring solution.
Whether monitoring an aging building, assessing construction-induced impacts, or managing the long-term safety of large urban structures, our technology helps engineers make informed decisions through continuous, reliable measurement data.
