【摘要】 基于WinCE嵌入式操作系统的仪器仪表的设计与开发日益得到人们的重视,它为开发者提供统一的编程接口,具有开发周期短、显示分析功能强大等特点。本文开发的基于平台级WinCE4.0的电力巡视仪正是这方面的尝试。论述了基于WinCE4.0平台的模块化体系结构及软硬件平台的搭建流程。将PlatformBuilder3.0作为基于WinCE4.0平台的嵌入式系统的开发工具,它提供了将定制的操作系统下载到目标平台的所有工具[1]。在平台的开发过程中主要分三部分完成:1.是构建平台,2.创建平台映像文件,3.将映像文件下载到目标设备上去。分析了WinCE4.0的实时性和嵌入性,总结了WinCE4.0平台下应用程序开发的特点。最后理解和掌握了操作系统的定制方法,电力巡视仪的软件设计(面向对象分析方法)与编程实现及与PC机的数据同步。电力巡视仪采用统一的Win32编程接口,多线程设计和模块化结构,可执行代码小,易于功能扩展。具有实时数据上传和下载、数据存盘、分析、统计等功能。便携式电力巡视仪作为电力管理信息系统的辅助部分,适用于工作分散且不需连续做业的工作环境,非常适用于移动巡视类工作。论文首先分析嵌入式操作系统的研究现状、技术背景、特点及应用。然后,以电力巡视仪为例,介绍了对“基于WinCE平台嵌入式巡视仪的设计与开发”这一课题的应用研究,包括需求分析、系统设计、主要子系统的编码实现、关键技术等主要部分。最后,本文对整个系统进行了客观的性能分析并提出了系统尚要解决的问题和改进目标。更多还原

【Abstract】 WinCE-based embedded operating system Instrument Design and Development is becoming more and more popular in our days. It provides a unified programming interface for developers with a short development cycle and powerful analysis function. In this paper, we try to develop a novel scouting instrument based on the power WinCE4.0.The WinCE4.0 operating system that based on the modular architecture and software platform structures processing are described in this paper. The PlatformBuilder3.0 is used as the development tool based on the WinCE4.0 of the operating system, which provides all the install tools from customized operation system to goal platform. During the platform development, this platform includes three parts. First, construct the platform. Second, create the platform image file. Third, download the image file to the goal equipment. The real-time performance and embedding performance are analyzed, and then the characteristic of application exploiture is summarized. Finally, the customize methods of operation system are mastered. The software design of power scouting instrument (Object Oriented Analysis methods) and program realization synchronize with data of personal computer. Win32 programming interface, multithreading design and modular structure are adapted in our Power scouting instrument. Few Executable codes and easy functional expansion. It has real-time data upload and download, Inventory data analysis, statistics and other functions. Portable scouting equipment of power as the assistantor of the PIS is suitable to apply to work without dispersion for the industry of the work environment and the mobile inspection categories. Firstly, this paper analyzes the Embedded System Research, technical background, characteristics and applications. Then, take the power of scouting instrument for example, introduce the "Development and Design of Portable Instrument Based on WinCE Embedded Operating System" research of subject, including requirements analysis, system design, the achievement of code major subsystems , the key technology part and so on.Finally, this paper analyses the capability of the entire system externally, then bring forward the problems which can not be solved and the improvement goals.更多还原
