| Abstract |
This study focused on developing a MANTiS wireless measurement system for performance-based monitoring of structures, utilizing ESP32 and MPU-6050 motion sensors. An experiment was conducted to verify the performance of the acceleration and frequency response of the MANTiS, determining its suitability for bridge monitoring. The experiment revealed errors of 0.90 % in the dynamic range and 0.40 % in the frequency range, indicating that the system is reasonably applicable for structural measurements. Furthermore, measurements of the data acquisition rate about communication distance and sampling rate confirmed that stable data acquisition is achievable without data loss, even at a sampling rate of 200 Hz over distances of up to 80 m. Finally, to evaluate the multi-module measurement capabilities of the developed MANTiS, vibration data were collected from six points to analyze its dynamic characteristics.
The analysis compared the performance of the MANTiS with that of a commercial wired measurement system. The results indicated that the developed MANTiS wireless measurement system exhibited a difference of 0.79 % in the primary mode and 0.09 % in the secondary mode when compared to the commercial wired system. Therefore, it is concluded that the MANTiS can be effectively utilized for measuring construction structures, such as bridges. |
