嵌入式喷码机控制系统的测试与开发

摘要

提出了一种以ARM9系列S3C2440为控制核心的喷码机控制系统,通过对单片机W77E58控制下的喷头波形测试,分析喷头工作原理.以WINCE嵌入式操作系统下的开发工具EVC为平台,设计驱动程序、测试程序、应用程序和图形用户界面；依据测试数据设计主控电路板、多输出电源、光电编码器、传感器及触摸屏等模块.该设计是一种低成本、多功能、先进的喷码机设计方案.%The temperature and pressure compensation algorithm was applied to ordinary gas and steam flow measurement; the compensation technology was introduced to obtain temperature and pressure compensation formula, including the comparative analysis of practical application and compensation formula so as to improve their compensation.
