移动手持终端是动车组管理信息系统的重要信息采集方式,以其灵活便捷的特点成为了固定式工位终端的有效补充。本文基于嵌入式Linux操作系统,搭建了交叉编译环境。在ARM处理器平台上,移植了嵌入式Linux操作系统,移植配置了嵌入式WEB服务器BOA、数据库服务器SQLite和文件服务器ftpd。通过CGI技术,实现了多台手持终端间的业务交互。开发实践表明,该平台为基于嵌入式Linux的手持终端应用程序的研发提供了基础。
Mobile handheld terminal is an important information acquisition system of EMU management information system, with its flexible and convenient features has become an effective complement to fixed station terminals. This article is based on embedded Linux operating system, build a cross-compiler environment. On the ARM processor platform, the embedded Linux operating system has been transplanted, and the embedded WEB server BOA, database server SQLite and file server ftpd have been transplanted. Through CGI technology, to achieve more than one handheld terminal business interaction. Development practice shows that the platform provides the foundation for the development of handheld terminal application based on embedded Linux.
