기계 상태 감시 및 진단을 위한 무선 계측 시스템의 개발

Abstract

This paper proposed an effective condition monitoring system based on wireless measurement technique. The application of wireless technique makes real-time and continuous monitoring are available. The development of wireless condition monitoring system can improve the performance that removed a current wired sensor and cable and reduce overall cost of condition monitoring. This system mainly consists of two parts: Transmitter(TM) and Base Station (BS). TM acquires dynamic signals from objective machine by integrated electronic piezo-electric (ICP) type accelerometer sensors. The acquired Direct Current (DC) signals are processed by analogue filters, and then converted to digital signal. Terminal board (programmed microprocessor) is inserted in the TM that transferred converted signal to BS through the WLAN protocol. BS composed of signal processing and monitoring part. The LabVIEW Library and visual C++.NET are utilize in this monitoring system Using this application; the wireless technique is employed to develop more stable and adequate condition monitoring system for high speed rotating machine.
