Abstract: with the transformation of the wind power industry to intelligent and digital, the traditional equipment monitoring and operation mode has been difficult to meet the needs of efficient, accurate and predictive maintenance. Based on optical fiber sensing technology and AI model, this paper designs and implements a set of "intelligent sensing online monitoring system". By integrating the functions of multi-source data acquisition, intelligent early warning, fault diagnosis, 3D visualization and intelligent operation and maintenance, the system constructs an intelligent monitoring system from the whole process of "perception transmission diagnosis operation and maintenance".
