摘 要 本课题来源于矿山多媒体应急通信系统研发任务，立足于目前国内煤矿应急救援技术现状，提出了一种基于WinCE环境的多媒体应急通信接收终端方案，本文主要任务是进行相关软件开发。 针对目前矿山救援应急通信存在的系统集成度不高、设备笨重、实时性较差等问题，软件开发部分引入了功能强大的WinCE 6.0嵌入式实时操作系统实现整个平台的开发，这是本文的一个创新点。本文手持终端设计中，基于通用性、便携性、低功耗、可扩展的思想，采用了嵌入式的开发方法，针对多媒体通信终端的软件需求进行了分析，明确软件模块实现的功能。开发过程中成功移植了E-boot和嵌入式WinCE到该终端中，完成了该平台软件的搭建并基于此平台，编写了键盘、视频等设备驱动程序，介绍了系统镜像和SDK的生成等相关问题，进行了相关应用软件的开发。 本文首先对课题的选题背景作了简单叙述，阐述了本课题的研究目的、意义和国内外研究的现状；接着深入探讨了整个软件开发平台的构建，其中包括操作系统的移植、驱动程序的开发、应用软件的开发、软件测试方法和过程，文章最后就开发中有待进一步深入研究和不尽完善的地方，对后续开发的内容作了展望。

This topic originates from the mine multimedia emergency communication system research and development duty, based on the current status of the domestic coal mine emergency rescue, a multi-media emergency communication receiving terminal program based on the WinCE environment is proposed, this article main task is to carry out the related software development. In view of the present mine rescue emergency communication existence's system integration rate is not high, the equipment is unwieldy, timeliness is bad and so on, the software development part introduces a powerful embedded real-time operating system WinCE 6.0 as the implementation of the development of the entire platform, which is an innovative of this article. This paper, in the course of the design of handheld devices, based on commonality, portability, low power consumption, using the embedded development methodology, analysis the requirement of multi-media communication terminals and define the functions of the software module. Successful transplantation of E-boot and Embedded WinCE operating system, which accomplished the software building of the platform, and based on this platform, wrote the device drivers such as hard drive, video and so on, introduced problems of system run-time image and the building of SDK, carried out the related application software development. In this paper, first briefly described the background of the topics, purpose of the study subjects, the followed by in depth exploration meaning and status of research at home outlined the and abroad; into building up the entire including hardware and operating system transplantation, development platform, driver development, hardware and software testing methods and process, In the end, the paper concludes a list of problems of the research and makes a prospect of the following development.
