动车组管理信息系统中的移动式手持终端设备,面临着业务处理逻辑复杂、实时性要求高、软硬件资源有限的挑战。Mini GUI具有小巧、高效、灵活等特点,适用于动车组管理信息系统移动式手持终端设备。本文梳理了动车组管理信息系统对移动式手持终端的业务要求,采用Linux为目标平台的手持终端设备,移植了Mini GUI图形支持系统,设计了基于该图形系统的应用程序架构,归纳了基本的应用程序规范,并以数据采集为例,验证了系统实时性,为后续应用程序的开发打下了基础。
EMU management information system in mobile handheld terminal equipment, facing business logic complexity, high real-time requirements, hardware and software resources limited challenges. Mini GUI has the characteristics of small size, high efficiency and flexibility and is suitable for EMU management information system mobile handheld terminal equipment. In this paper, the business requirements of EMU management system for mobile handheld terminal are summarized. The handheld terminal device with Linux as the target platform is ported. The Mini GUI graphics support system is transplanted. The application architecture based on this graphic system is designed and the basic Application specifications, and data acquisition, for example, verified the system real-time, laid the foundation for the subsequent application development.
