Coal mill operation safety online evaluation method based on intuitionistic fuzzy clustering

The invention discloses a coal mill operation safety online evaluation method based on intuitionistic fuzzy clustering, and the method comprises the following steps: firstly, carrying out the clustering of historical operation data samples of coal mill equipment through employing the intuitionistic fuzzy clustering; identifying the safety range of each influence factor characteristic index of the coal mill by combining the evaluation of offline experts on historical operation data of coal mill equipment and a grey fuzzy comprehensive theory; secondly, according to the operation data of the coal mill equipment and the residual interval of the safety range, making a principle of constructing importance among all influence factors of the coal mill equipment on line; mining potential characteristics among historical operation data of the coal mill equipment by adopting machine learning, and formulating an online construction coal mill equipment operation state scoring principle; finally, gray fuzzy comprehensive
