AI Technical Summary

Technical Problem

Changes in the position and size of the furnace holes on the electrolytic cell lead to an extended alignment time of the measuring tool, inefficient efficiency and high risk of tool damage.

Method used

By identifying the furnace hole image of the electrolytic tank, distinguishing the two levels and the tank temperature measurement tasks, different alignment methods are used: the two levels of measurement directly identify the furnace hole position, the tank temperature measurement first recognizes the furnace hole state, and use dynamic threshold segmentation and optical center of gravity to improve accuracy, and control the alignment of the measurement tool with the furnace hole.

Benefits of technology

Improves the alignment efficiency of the measuring tool and the furnace hole, and reduces the risk of damage to the measuring tool.

Abstract

The invention relates to the technical field of furnace hole identification, and discloses an alignment method and alignment device for a measuring tool and a furnace hole, and a measuring mechanism. The alignment method comprises the following steps: after obtaining a furnace hole image of the electrolytic bath, determining the type of a measurement task to be executed by a measurement tool; under the condition that the measurement task type is a two-level measurement task, determining a furnace hole in the electrolytic bath as a first furnace hole; identifying the furnace hole position in the furnace hole image, and controlling the measuring tool to be aligned with the first furnace hole according to the furnace hole position; under the condition that the measurement task type is the cell temperature measurement task, determining the furnace hole in the electrolytic cell as a second furnace hole; identifying the furnace hole state in the furnace hole image, and controlling the measuring tool to be aligned with the second furnace hole according to the furnace hole state. The aligning efficiency of the measuring tool and the furnace hole can be improved, and the risk that the measuring tool is damaged is reduced.
