基于光纤的远程IO端口控制系统

摘要

介绍了一种基于光纤的远程IO端口控制系统，通过将光纤、以太网与嵌入式系统结合，采用VB6.0上位机软件实现远程通讯测试，提出了一种远程控制IO端口数据双向传输的解决方案。本系统以单片机MCF5223X系列芯片为主控模块的核心，从IO端口采集数据后由光纤传输至远端主机，远端主机通过VB6.0分析处理数据，使得远端主机与IO端口数据实时双向传输，实现远程控制IO端口的功能。本文给出了系统结构图和软件测试通讯图。%Introduces a remote IO port control system based on fiber optical.This paper proposes and realizes a remote IO port control systerm which combines the fiber optical and internet with embedded system and uses VB6.0 software to realize remote communication test.The system adopts the MCF 5223 series chip as the core of the main control module,collectting data from the IO port,which are transmitted through the fiber optical and finally received anf displayed real-time on the remote PC with the program designed by the VB6.0.
