Summary
This study developed a Bluetooth wireless load cell system to monitor construction loads, preventing collapses. The system provides real-time data and warnings, enhancing worksite safety and preventing accidents.
Area of Science:
- Civil Engineering
- Structural Health Monitoring
- Construction Safety
Background:
- Temporary construction facilities are prone to collapse, leading to severe accidents and loss of life.
- High concrete placing heights and concentrated worker loads can exceed structural capacity, triggering collapses.
Purpose of the Study:
- To develop a real-time load monitoring system for construction sites.
- To prevent collapse accidents by detecting and warning about excessive loads.
Main Methods:
- Developed a Bluetooth wireless load cell system for digital load measurement.
- Designed and manufactured a Bluetooth-enabled load cell.
- Verified performance using 3D finite element analysis and experimental tests.
- Constructed a notification system for dangerous load levels.
Main Results:
- Confirmed the load distribution patterns by position.
- Established a method for real-time numerical and graphical data confirmation.
- Evaluated the practical application of the system with field-test data.
Conclusions:
- The developed wireless load monitoring system effectively detects and warns of dangerous loads.
- The system enhances construction safety by providing real-time load data and preventing collapses.
