【摘要】 阐述了基于嵌入式Linux的Kiosk系统的设计思路和设计方案及实现的体系结构。本系统设计中采用了基于B/S(Browser/Server)架构的三层设计模式;业务层采用Web服务技术完成与数据层的交互;表现层使用Ajax技术增加系统对用户的亲和力;而数据层由Web服务提供商WSP(Web Service Provider)进行维护。在Kiosk终端,采用VIA EPIA Mini-ITX的开发板作为硬件平台,按照需求定制的嵌入式Linux作为软件系统。在系统实现过程中,广泛采用了开源软件包,如Tomcat,Apache,Java等,并集成了由WSP提供的众多服务项目,如Global Weather,Real-Time Market等。本系统在实际应用中运行稳定、高效、易于维护,获得了满意的结果。更多还原

【Abstract】 In this paper, the design and implementation of an embedded Linux Kiosk System are given. The design model of 3-Layer based on B/S structure is adopted. Web Service based on technology in the service layer is applied to realize the interaction with data layer; friendly user interface in the presentation layer is provided by Ajax technology; The WSP (Web Service Provider) is responsible for the maintenance of the data layer. VIA EPIA Mini-ITX development board is selected as the hardware platform and an Embedded Linux is built as the software system according to the requirement. Open-Source Software such as Apache, Tomcat, Java is employed. Many services are integrated by WSP in this system such as Global Weather, Real-Time Market etc. The system is already applied in practice and it is of high stability and efficiency as well as easy maintenance, and satisfactory result is obtained.更多还原
