Design of an Automatic Powder Dosing Control System Based on Dual ARM Core

Abstract

In industries such as pharmaceutical, petrochemical, and food processing, automated powder doses are increasingly favored over traditional manual methods due to their higher productivity and accuracy. Despite the advances in existing technologies, challenges such as weighing accuracy, cost and limited secondary development capabilities remain. This paper presents an automated powder dosing control system based on a dual ARM core architecture. By using dual ARM core processors, the system enhances the hardware architecture and control flow to achieve accurate powder weighing. The experimental results show that the average errors of three kinds of powders with different physical properties are 0.089g, 0.012g, and 0.054g respectively, which meet the design specifications.
