Abstract: PURPOSE: A condition monitoring method for recognizing a fault in an offshore wind power generation system and a device thereof are provided to wirelessly transmit the operation condition of an offshore wind power generator through BCDMA(Binary Code Division Multiple Access) technology and perform signal analysis and fault detection in a CMS(condition monitoring system) terminal based on corresponding data. CONSTITUTION: An analog vibration signal sensed in a sensor unit(20) is converted into a digital vibration signal through an ADC(Analog to Digital Converter)(30). The digital vibration signal is converted into BCDMA-based data in a slave data communication unit(50). A master data communication unit(60) decodes the data. A CMS terminal(90) analyzes the inputted vibration signal. The CMS terminal detects normal operation condition or fault/malfunction condition.
