Coal mill risk assessment method and device, electronic equipment and storage medium

Abstract

The invention provides a coal mill risk assessment method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining subjective experience indexes corresponding to a plurality of risk assessment indexes in a risk state of a coal mill, carrying out the weight sorting of the subjective experience indexes, obtaining a judgment matrix, and obtaining the subjective weight of a fault index of the coal mill based on the judgment matrix; determining posterior probabilities of the plurality of risk evaluation indexes, and determining objective weights of the risk evaluation indexes based on the posterior probabilities; a coal mill real-time data set and an evaluation set corresponding to the risk evaluation indexes are obtained, and a fuzzy evaluation matrix is obtained based on the coal mill real-time data set and the evaluation set; and obtaining a risk assessment result of the coal mill based on the subjective weight, the objective weight and the fuzzy evaluation matrix. According to the method, the subjective weights and the objective weights corresponding to the plurality of risk evaluation indexes are combined with the fuzzy evaluation matrix corresponding to the real-time data set of the coal mill, so that comprehensive and dynamic risk evaluation on the coal mill is realized.

Description

technical field [0001] The invention relates to the technical field of coal mills, in particular to a risk assessment method, device, electronic equipment and storage medium for a coal mill. Background technique [0002] Coal mill is the main energy supply equipment in cement plant, which is responsible for grinding raw coal into fine coal powder. In the process of pulverized coal preparation, the equipment safety and component aging of the coal mill body affect the safe production and operation of the coal mill. Accurate risk assessment of coal mill operation risks and timely discovery of potential safety hazards can not only provide an important basis for planned maintenance of cement plants, but also ensure the safe and stable operation of cement production. [0003] Therefore, establishing a scientific and reasonable coal mill risk assessment system has important practical significance for finding out the main problems and weak links of coal mill failures. At present, ...

AI Technical Summary

Problems solved by technology

The current risk assessment index system for coal mills in cement plants is still immature, and there is no comprehensive risk assessment for coal mills at the level of coal mill operation status; on the other hand, the current risk assessment methods are difficult to reflect the real-time dynamics of risks Variety
