AI Technical Summary

Technical Problem

In existing technologies, the monitoring methods for the grade of refined materials have long detection cycles and significant lag, which cannot meet the real-time data requirements under continuous production conditions. The sampling points are limited and random, resulting in insufficient representativeness of the test results and making it difficult to achieve continuous, accurate and stable online monitoring.

Method used

A pulse-constrained four-domain coupled hierarchical inversion algorithm is adopted, which combines multi-source raw data, including incident ray intensity, transmitted ray intensity, electromagnetic signal, particle image and bed vibration data. By constructing an effective enrichment potential index and a jump suppression factor, a high-dimensional mapping and time consistency constraint of fine material grade are achieved, thereby improving the stability and response speed of detection.

Benefits of technology

It enables continuous, accurate, and stable online monitoring of raw material quality, avoiding the lag and misjudgment problems of traditional methods, improving the representativeness and anti-interference ability of the test results, and maintaining the stability of rapid response capability under stable working conditions.

Abstract

The present application relates to concentrate grade monitoring field, especially to a kind of jig enrichment process concentrate grade monitoring method.Content includes: in the same time window, multiple original data are synchronously collected, and preliminary processing is carried out, to obtain monitoring basic state parameter;Through the calibration process before monitoring, basic reference data is obtained.Based on monitoring basic state parameter and basic reference data, introduce pulsation constraint four-domain coupling recursive inversion algorithm, combined with recursive inversion mode, construct effective enrichment potential index and jump suppression factor, and obtain concentrate grade.Solve the problem that the detection cycle of traditional concentrate grade monitoring method is longer, there is obvious hysteresis, cannot meet the demand of real-time data under continuous production conditions, at the same time, sampling point is limited and has randomness, detection result is insufficiently representative, it is difficult to fully reflect the real state of entire discharge stream, so that concentrate grade in jig enrichment process is difficult to realize continuous, accurate and stable online monitoring.
