英文摘要	The present invention relates to a working condition state modeling and model correcting method, comprising collecting data, and arranging the data in a chronological order to form a time sequence data set; preprocessing the time sequence data set; clustering the preprocessed time sequence data set, computing a central point data set of the duster, and generating a working condition data set and a working condition process data set; counting a working condition transition probability for the working condition process data set to form a working condition transition probability model data set; collecting the data, and detecting and processing the data; computing a working condition state transition mode phase by phase and processing. The present invention is based on a counting modeling method, introduces expert prior knowledge to correct the established model gradually, enables the model range to cover the overall system working condition state and solves the problem of low coverage rage in the mechanism analysis modeling methods and the counting modeling method, The present invention can be used as the input of an abnormal working condition diagnosis method, and can effectively improve the accuracy rate of abnormality diagnosis.
