사물인터넷 기반 무선 상태 모니터링 시스템 개발
Abstract
With the advancements in sensor technology and open source-based controllers, the development of a condition monitoring system has become relatively easier. However, there is not enough well-organized information to develop condition monitoring system. Therefore, we present a wireless condition monitoring system based on the Internet of Things (IoT) by using an open-source controller. The developed wireless condition monitoring system consists of a sensor module, data processing unit, and condition monitoring program. This system can measure 3-axis accelerations of frequency up to 1.5 kHz, with a frequency resolution of 0.05 Hz to 20 Hz, and temperature. The developed condition monitoring system provides statistical time information and frequency spectrum for advanced condition diagnosis. Furthermore, the condition diagnosis function for low-speed rotating machines was implemented effectively.
