摘要

针对高炉料面检测中多传感器数据难以直接应用的问题，提出了同时融合高度和温度数据，结合布料机理对非检测点进行估计来实现料面检测的方法。首先，对高炉异类传感器得到的多源数据进行时间和空间配准；然后，根据高炉高度与温度的机理关系，提出环域配准融合思想，用高炉料面温度求出对应的高度；最后，结合料面的物理性质，将理论料形与多源数据进行贝叶斯融合得到高炉料面图像。以某钢铁企业2 500 m

高炉现有检测设备为基础进行了现场实验，实验结果表明，与料形估算法相比，本文检测方法的测量精度提高了5.4%，料面分辨率提高了0.43。该方法使得高炉料面形状检测更加精准，为高炉节能减排操作提供了必要的指导。

Abstract

In consideration of the difficulty of directly using the multi-sensor detecting data in detection of the burden surface of a blast furnace(BF)

a novel approach is put forward. The method fuses height data and temperature data and makes use of material mechanism to estimate the non-detecting points to obtain the burden surface. First

multi-sourced data obtained by dissimilar sensors are dealt with in both the time dimension and the spatial dimension. Then

a specific means of loop domain registration is proposed to derive the height of burden surface from the temperature of burden surface. Finally

by combing with the physical properties of surface shape and using Bayes fusion for the theoretical shape and multi-sourced data

the image of burden surface shape of BF is acquired. The experiments indicate that the measurement accuracy has improved by 5.4%

and the resolution of BF has improved by 0.43 as compared with that the traditional burden surface shape estimating method. The method provides necessary guidance for energy saving operation of blast furnaces.
