Abstract

The invention discloses an oil refining process online optimization method and an oil refining process online optimization device based on a case library and steady state detection. The oil refining process online optimization method comprises the steps of: acquiring historical data from each preset time length of a database of a factory, generating historical cases and storing the historical cases into a historical case library; acquiring current production data from the database of the factory, and generating a current production case; and performing fuzzy matching on the current productioncase and the historical cases in the historical case library to obtain the historical case which satisfies a preset condition with fingerprint data of a current production state, sorting the historical cases according to assessment data to obtain a referable historical case set superior to the current production case, so as to optimizing the oil refining process according to the historical case set. The oil refining process online optimization method effectively solves the practical problems and defects of the related art, that is, solves the problems of poor real-time performance and precision of data, large calculation cost and the like, can realize real-time online optimization of the oil refining process, and is simple and easy to implement.
