The invention discloses a distributed industrial process monitoring method based on a variable weighting PCA (Principal Component Analysis) model. The method mainly solves a problem that hidden useful information cannot be comprehensively explored when a PCA model is built because a traditional PCA based fault detection method fails to sufficiently consider the correlation difference between measurement variables.
