基于ARM920T嵌入式Linux(R)/Qt4的点菜系统设计

摘要

In order for deficiency of meal-ordering system which can not oriented towards consumer directly and flaws of real-time and interactive function, a new type of meal-ordering system with embedded Linux2.6.28/Qt4.5 based ARM was proposed.The whole system platform is based on S3C2440A board with high-performance 32-bit ARM920T core processor.In this system Qt4.5 that is ported to ARM constructs development environment.The paper analysis in detail each function component and procedure of database design.Besides the connection and implementation between Qt4.5 and embedded database SQLite3 is also mentioned in the paper.Finally test results show that dish-ordering system that run on the ARM is stable, reliable ,operational and valuable.%针对现有点菜系统的解决方案不能直接面向消费顾客以及实时性和互动性差等缺点,设计了一款基于ARM的新型嵌入式Linux2.6.28/Qt4.5点菜系统.系统整体结构是以高性能的32位ARM920T内核的S3C2440A为核心处理器,构建了Qt4.5开发环境并移植到ARM平台上.详细分析了系统各功能模块及数据库的设计方法,并阐述了Qt4.5与嵌入式数据库(SQLite3)的连接与实现.验证了该设计在ARM平台上运行稳定,可操作性强,具有良好的经济效益.
