基于ARM9微处理器的嵌入式手持无线点菜系统的设计

Development of Embedded Handheld Wireless Order System Based on the ARM9 Processor

针对现有点菜系统实时性和移动性差的问题,设计了一个基于ARM9S3C2440的新型嵌入式手持无线点菜系统.该系统在S3C2440内核基础上实现了μC/OSⅡ操作系统的移植,在图形构建软件μC/GUI下构建了整个系统的图形界面,根据设计需求实现了对点菜系统的程序功能.测试结果表明:在实时性和测试距离上效果良好,达到了应用指标.该设计对提高餐饮企业的服务质量,降低费用有积极的推动作用.

To solve the problems of traditional ordering systems, such as poor mobility and real-time, a new embedded system of ordering dishes based on ARM9S3C2440 was designed. First of all, theμC/OSⅡwas transplanted in basis of the kernel of S3C2440,then the graphical interface of the whole system was constructed by using theμC/GUI; Finally, the function of the ordering system was implemented according to the actual requirements. The test shows that it achieves the application goal both in real-time and test distance. The design is significant for improving quality of service and reducing the expenditure of restaurant.
