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. According to the method, diversified weighting is performed on training data by using the correlation between each measurement variable and other measurement variables in the process, and a corresponding PCA fault detection model is built for the weighted data so as to carry out distributed process monitoring on a production object. The correlation strength between the measurement variables can be reflected in a prominent manner by implementing weighting on the training data by using the size of a correlation value. On this basis, hidden information extracted by using a PCA algorithm can better describe the operating state of the corresponding measurement variable. In addition, a plurality of PCA fault detection models are utilized to implement distributed process monitoring, so that the diversity of the extracted process data hidden information can be well ensured, and thus comprehensive description for the process operating state is realized. Compared with a traditional PCA based fault detection method, the method disclosed by the invention has a more comprehensive process operating state description ability, and can acquire a more reliable and more excellent fault detection effect.
