Intelligent rotating speed monitoring system of fan and monitoring method of intelligent rotating speed monitoring system

The invention relates to the field of intelligent monitoring of fans, and particularly discloses an intelligent rotating speed monitoring system of a fan and a monitoring method of the intelligent rotating speed monitoring system. And comprehensively monitoring the rotating speed of the wind driven generator by using time domain characteristics and frequency domain characteristics of waveform data collected by an annular encoder based on a deep neural network model. Therefore, not only can the rotating speed of the fan be accurately measured, but also the stability of a unit can be improved, and a large amount of maintenance cost is avoided. 本申请涉及风机智能监控的领域，其具体地公开了一种风机的智能转速监控系统及其监控方法，其采用人工智能的监控方法，基于深度神经网络模型通过使用环形编码器采集的波形数据的时域特征和频域特征来综合对于风力发电机转速进行监控。这样，不仅能够准确地测量风机转速，还能够提高机组的稳定性，进而避免花费大量的维修成本。
