基于ARM的嵌入式电脑丝袜机控制系统设计

ARM-based Control System Design of Embedded Computerized Hosiery Machine

针对国内丝袜机计算机控制系统在稳定性、扩展性、可移植性等方面较差的问题,设计了一种基于ARM的嵌入式电脑丝袜机控制系统。在介绍控制系统的设计要求、基本原理及功能实现的基础上,提出了该系统采用ARM920T架构的32位工业级处理芯片S3C2440A作为主控制器,采用ARM Cortex-M3内核的32位微处理器STM32F103作为现场总线的从节点控制器;并详细分析控制系统的工作流程,以及主控制器和底层功能模块的软、硬件实现方法。实践证明,该控制系统具有集成度高、稳定性好、实时性强等优点。

In terms of the problem of bad stability, extensibility and transportability of control system of domes-tic hosiery machine, the paper designs a new kind of control system for embedded computerized hosiery machine based on ARM. Based on the introduction of design requirement, basic principle and function realization, it pro-vides that the 32-bit industrial-grade processing chip S3C2440A of ARM920T framework is the master controller, and the 32-bit microprocessor STM32F103 of ARM Cortex-M3 core is node controller of field bus; besides, it ana- lyzes in detail the working processing, as well as the achieving method of software and hardware of master con-troller and bottom function-realizing module. This control system presents some obvious advantages, such as high integration, good stability and strong real-time control and so on.
