【摘要】 本论文的主要内容是研究和开发一个半导体设备的数据采集控制系统。该系统采用eBox作为硬件平台和嵌入式Linux作为操作系统。根据用户的要求,在Qt/Embedded开发环境下,用C++语言完成了系统应用程序的设计。论文分析了嵌入式系统的硬件架构和嵌入式操作系统的特点,研究了应用嵌入式Linux操作系统的基础。根据用户的设备控制要求,设计了半导体数据采集控制系统的方案,提出系统的主要功能模块,确定嵌入式硬件平台eBox4850。搭建了系统软件环境,分析了Linux内核结构,重点研究了根文件系统的生成和内核的裁剪,实现嵌入式Linux在eBox4850上的完整移植。在PC端搭建了Qt/Embedded开发环境；用于开发和运行目标机上的应用程序。编写了数据采集控制系统的应用程序,实现了对多个传感器的数据采集、处理和显示,并根据结果对系统进行控制。开发工作包括系统的总体设计,控制软件设计和一套相对完整的串行通信协议的制定。系统实现了课题的要求,并在进行大量测试时运行良好,证明了将先进的嵌入式软硬件技术应用到数据采集控制系统设计中,具有一定的可行性和应用价值。
【Abstract】 This paper focuses on the research and development of a Data Acquisition and Control System based on semiconductor equipment. The system employs eBox as its hardware platform and Embedded Linux as its Operating System. According to the requirements of users, in the Qt/Embedded development environment, the system application is completed with C++programming language.The thesis analyzes the hardware architecture of Embedded System and the characteristics of Embedded Operating System, and studies the basis of employing Embedded Linux Operating System. To fulfill the user’s requirements on device control, the proposal of the Data Acquisition and Control System is designed, the core function modules are put forward, the embedded hardware platform eBox4850 is established. The system’s software environment is set up, the Linux Kernel structure is analyzed, and the creation of root file system and the reduction of Linux Kernel is emphasized, finally, the porting of Embedded Linux to eBox4850 is completed. For the host, the Qt/Embedded development environment is set up to develop and verify the application programs. The application program of Data Acquisition and Control System is designed, which works well in data acquisition、data processing and display for a couple of sensors, and the results are the basis according to which users control the system.In accordance with the requirements of task, the system works well in a large number of tests, which proves that it is feasible and of application value to employ the advanced embedded software and hardware technologies in the Data Acquisition and Control System.
