Vertical mill operation regulation and control system based on data mining and method thereof

Abstract

The invention discloses a vertical mill operation regulation and control system based on data mining and a method thereof. The method is characterized by using an integration characteristic screening method to carry out mining analysis on work condition data and acquiring a vertical mill health state assessment index; carrying out cluster mining analysis on a work condition state, acquiring a characteristic of each condition cluster, and acquiring each state distribution condition in historical work conditions; defining operation state types in the historical work conditions and acquiring a stable mode condition database; using an ARIMA algorithm to carry out training model on a determined characteristic value in a vertical mill health state characteristic acquisition module and predict a parameter change trend, and using a predicted value to assist state identification; combining the predicted value given by an ARIMA model, determining a vertical mill operation state; when the state is determined to be abnormal, reading a work condition record in the stable work condition mode database, acquiring a recommended regulation and control target value and regulating and controlling a controllable parameter at the moment. In the invention, vertical-mill qualitative and quantitative regulation and control suggestions can be accurately provided and a mill machine can work stably for a long time.

Description

technical field [0001] The invention relates to the field of slag grinding in the field of cement process industry, in particular to a data mining-based vertical mill operation control system and method. Background technique [0002] The vertical mill is a kind of equipment used to grind large particles of slag and other materials into fine particles. It mainly grinds waste slag produced in building materials, chemical industry, steel and other industries to realize the reuse of waste slag. The fine powder obtained by grinding is usually used as Raw materials for cement production. However, the process of slag grinding system is complicated, the working environment is harsh, and the long-term high-load operation. At the same time, the vertical mill raw material grinding process has the characteristics of strong coupling, nonlinearity, and large hysteresis, and there are physical and chemical changes. Establishing an accurate vertical mill It is very difficult to model the m...

Problems solved by technology

[0004] In the various models of the above-mentioned vertical mill raw meal grinding process, most researchers only explored the one-to-one relationship between the indicators in the vertical mill operation process and their influence on the vertical mill operation, but the vertical mill is a multi- A system in which variables are closely related to each other. The variables affect each other. A change in one of the indicators will affect other indicators, which in turn will have a great impact on the overall operating status of the vertical mill.
