摘要
一种具有网络功能的嵌入式现场控制器,其主机以高性能ARM9芯片S3C2440作为中央处理器,增强型高速单片机作为采集板控制器,采用RS422总线实现控制器主机和采集板的C/S结构。控制器主机的软件以嵌入式Linux操作系统为平台,采用嵌入式GUI开发系统miniStudio进行开发。该控制器能够采集、显示、存储工业现场常见信号,并能通过Ether-net对控制器实现远程访问。
This paper introduces a embedded networking field controller with high performance ARMg- S3C2440 chip as central controller. The acquisition board is enhanced high speed singlechip controller based on RS422 bus used in C/S structure. The controller software in the host computer takes embedded Linux operating system as the platform, which is developed by the latest embedded GUI- based miniStudio development system. The controller is able to collect, display and save common signals in the industrial site and can remote access controllers via Ethernet.
