东北石油大学本科生毕业设计（论文） PAGE 东北石油大学本科生毕业设计（论文） Ⅰ 摘 要 随着现代工业和科学技术的迅速发展，在众多的工业部门中都会遇到各式各样的粉尘浓度、粒度的测量问题，这不仅关系到环境问题，而且直接危害人们身体的健康。因此粉尘浓度、粒度的测量越来越重要。 论文首先简要介绍了一些关于嵌入式系统的基本概念和嵌入式系统的发展现状，然后简述了基于Linux系统和S3C2410处理器的嵌入式系统开发平台的基本架构及各个组成部分的开发流程。本文主要讨论的是粉尘浓度传感器DSM501监测空气中粉尘浓度的设计方法，及相应硬件驱动程序的开发，同时引入高性能嵌入式GUI系统开发工具包Qt/Embedded，并开发系统的图形用户界面。在此基础上还介绍了基于Linux与S3C2410的交叉编译环境的建立、嵌入式系统开发中广泛使用的NFS服务器的建立及网络环境的搭建等。 关键词：嵌入式系统；Qt/Embedded；Linux；粉尘浓度 Abstract With the development of Modern industry and Technology, more accuracy means are needed by all kinds of measurements of dust concentration and granularity. Whether or not to meet these challenges is not only a question about environment, but also a question which concerns healthy of people. The technology on this field is drawing much more attentions. This thesis introduces some basic concepts about embedded system at the beginning, and then introduces the basic components and the characteristics of the embedded system which is based on S3C2410. This thesis focuses on the monitoring of air dust concentration sensor DSM501 design method of dust concentration, and the corresponding development of hardware drivers, while the introduction of high-performance embedded GUI system development toolkit Qt / Embedded, and the development of the systems graphical user interface. On the base of the above, the paper also introduces the setting of the environment of cross compiling,the widely used NFS server in the development of embedded system, the foundation of network and so on, so as to add a supplement of the contentof the whole thesis.
