AI Technical Summary

Technical Problem

In existing sintering point monitoring technologies, thermocouple measurement sensors are difficult to install and cannot be precisely controlled, resulting in high parameter dispersion and inaccurate monitoring of the sintering point location.

Method used

Temperature-sensing optical fibers are arranged along the running direction of the sintering machine trolley to collect temperature values ​​of multiple fiber segments in real time. Based on a preset coordinate system, curve fitting is performed to determine the point with the highest temperature value to locate the sintering point.

Benefits of technology

It improves the accuracy of sintering point location monitoring, enabling precise determination of the specific position of the sintering point relative to the travel area of ​​the sintering machine trolley, thus optimizing the sintering process.

Abstract

The application discloses a sintering point monitoring method and device of a sintering machine, a storage medium and computer equipment. The method is applied to a monitoring host in a sintering point monitoring system of the sintering machine, and the method comprises the following steps: selecting a first preset number of target optical fiber sections from a plurality of optical fiber sections of a temperature sensing optical fiber, and collecting temperature values at the target optical fiber sections in real time; determining the temperature values as first coordinate components of the target optical fiber sections on a first coordinate axis in a preset reference coordinate system, and determining second coordinate components of the target optical fiber sections on a second coordinate axis in the preset reference coordinate system; performing curve fitting based on the first coordinate components and the second coordinate components of each target optical fiber section to obtain a fitting curve corresponding to the temperature sensing optical fiber; determining a highest temperature point on the fitting curve, determining a sintering point coordinate component of the highest temperature point on the second coordinate axis, and determining a sintering point position based on the sintering point coordinate component. The above method can accurately monitor the sintering point position.
