AI Technical Summary

Technical Problem

Existing technologies are unable to simultaneously quantify the ratio of high-value metals to impurities and the three-dimensional spatial distribution characteristics of an entire piece of scrap steel, resulting in distorted reprocessing cost assessments and a lack of a value scoring mechanism that integrates component ratios and distribution patterns, causing sorting decisions to be disconnected from economic benefits.

Method used

A multi-sensor fusion system is used, including X-ray composition analysis sensors, high-resolution visual sensors and laser profile scanning sensors, to simultaneously collect the material composition, surface morphology and three-dimensional geometric distribution data of scrap steel. Combined with the central processing module, a three-dimensional material distribution map is constructed, and a comprehensive value scoring formula is used to calculate and drive a three-way sorting mechanism. Blockchain evidence storage and machine learning are used to optimize the decision threshold.

Benefits of technology

It achieves precise quantification of the economic value of scrap steel, improves the recycling rate of high-value metals, reduces reprocessing energy consumption, and ensures the reliability and traceability of the sorting process through re-inspection buffer and blockchain evidence storage mechanism, thereby maximizing resource utilization.
