Abstract:To detect vibration of wind power generator,reducing damage caused by vibration,this paper researched and designed vibration measurer for the wind power generator.The introduction of the structure of non-contact vibration sensor improved the durability of the instrument,realizing the two-dimensional vibration testing.By way of the experiment,establishing the relationship between the current of the sensor and the displacement,based on the mathematical models of the sensor,through information processing and data analysis,a test including the amplitude,the frequency and the position was realized simultaneously,and to its feasibility,the necessary proof is made.Using VB as a tool,to develop the humanmachine interface of the realtime monitoring,set the value of vibration alarm and register alarm information.
