Equipment health management abnormity positioning method based on event association

The invention discloses an equipment health management abnormity positioning method based on event association, and relates to the technical field of equipment health management. The method comprises the following steps: acquiring standard fault feature data and to-be-detected fault feature data in an equipment operation process; preprocessing the obtained standard fault feature data and the to-be-detected fault feature data; respectively constructing a standard fault feature matrix and a to-be-detected fault feature matrix according to the preprocessed standard fault feature data and the to-be-detected fault feature data; calculating an abnormal matching degree according to the constructed standard fault feature matrix and the to-be-detected fault feature matrix, and determining abnormal matching features; and determining an abnormal positioning result according to the abnormal matching features of the standard fault feature matrix and the to-be-detected fault feature matrix. According to the invention, real
