Abstract

A method and an apparatus for establishing a model for a cement pre-grinding process, and application thereof are provided. The method comprises: determining each parameter; determining a qualitativerelationship between the nodes by taking each parameter as a node, and establishing a preliminary fuzzy cognitive map; solving a correlation parameter value; and substituting the correlation parametervalue into the preliminary fuzzy cognitive map to acquire a fuzzy cognitive model. The apparatus comprises: a parameter determining unit, a preliminary fuzzy cognitive map establishing unit, an arithmetic unit and a fuzzy cognitive model acquiring unit. The application is that the fuzzy cognitive model is applied to the parameter prediction in the cement combined grinding pre-grinding process, and comprises the steps of: using actual production data at the time t, a qualitative relationship of the model, a correlation parameter value and a conversion function to calculate a state value of each node of the model at the time t+1; and after denormalization, obtaining a predicted value of each parameter on site at the time t+1. According to the technical scheme of the present invention, the problem that the requirement of the cement plant for improving the quality cannot be satisfied due to ignoring certain parameters in actual production is solved.

Description

technical field [0001] The invention relates to the field of intelligent cement production, in particular to a method, device and application for establishing a model suitable for the cement pre-grinding process. Background technique [0002] Cement pre-grinding is an integral part of cement combined grinding. If you want to elaborate on cement pre-grinding, you must first have a preliminary understanding of cement combined grinding process. The combined cement grinding process includes an open-circuit combined grinding process with a roller press and a closed-circuit combined grinding process with a roller press. The combined grinding system with roller press is the production system adopted by the vast majority of cement manufacturers in my country. Closed-circuit combined grinding process with roller press such as figure 1 shown. Open-circuit combined grinding process with roller press such as figure 2 shown. [0003] In the cement combined grinding process, the gri...
