환경시설물 대상 MEMS 가속도 센서 실증사례 연구 = Empirical case study of utilizing MEMS accelerometers for environmental facilities

다국어 초록 (Multilingual Abstract)

Environmental facilities are required to recover quickly from earthquake damage and maintain normal function. On the other hand, they are excluded from the facilities subject to seismic acceleration measurement obligations under the current regulations. The MEMS acceleration sensor module can reduce the cost of burying communication lines in the existing SHM system. In addition, it has excellent scalability because it can respond quickly to changes in the measurement points. Therefore, this study established a pilot monitoring system using MEMS acceleration sensor modules for two environmental facilities and confirmed the possibility of replacing the existing SHM system through analysis of the empirical and measurement data for two years. In measuring the ambient vibration environment, the main functions of the module, such as shock vibration detection, 24-hour vibration monitoring, and measurement data storage, were verified. In seismic wave measurement data analysis, the data and waveforms measured by the module for earthquakes in 2022 and 2023 were analyzed. Using the acceleration measured by the module, building safety could be evaluated in connection with disaster standard operating procedure (SOP), and secondary damage can be reduced by linking with the process management system of environmental facilities in real-time.
