【摘要】：论文基于的研究项目来源于2009年国家科技部科技人员服务企业行动项目“面向高危场所的一体化数据采集仪”（项目编号2009GJE00021）。嵌入式技术是21世纪最具生命力的高新技术之一，而嵌入式远程桌面控制设计则是当今网络环境下数字化设计的一个重要发展方向。本文便是结合安全生产应用中对远程嵌入式设备的可见可记录和可操作等需求，分析研究如何克服硬件自身的差异性，将远程桌面控制功能移植到嵌入式内核中，以支持异地用户能够通过网络控制远程嵌入式设备，实时便捷地获取现场数据，达到将操作与设备拆分开来的目的。首先，本文通过需求分析，选择了Windows CE操作系统作为软件平台，基于ARM内核的S3C6410微处理器作为硬件平台，并设计了整个远程桌面控制系统的软硬件实现方案。在方案的实现过程中，将基于S3C6410硬件平台的BSP开发作为基本点和关键点进行研究，通过分析其中的Boot Loader层的源码构架，完成了在Boot Loader层对CPU、以太网口以及TFTP连接等的初始化设计工作，使操作系统可以通过以太网进行Windows CE映像的加载；通过分析其中的OAL层的设计原理，完成了在OAL层对操作系统的内核初始化、KITL的I/O控制接口以及串口等操作的程序设计和调试工作，使Windows CE内核可以与硬件平台进行交互通信；通过分析Windows CE的缓存结构，采用了四路组相联的设计方案以优化缓存、提升Windows CE的运行效率。其次，对设备驱动进行了分类，基于MDD/PDD模型设计了视频驱动程序，基于UAM模型设计了音频驱动程序，实现了嵌入式设备对音、视频信息的采集。然后，完成了Windows CE系统的远程桌面控制组件的内核定制、无线通信模块的加载、内核编译与系统启动等工作。最后，搭建测试环境，完成了对整个系统的性能测试与分析。经过服务器端、客户机端以及无线局域网等环境的测试，系统在远程登录、远程文件传输、图像采集以及缓存性能等方面的设计均达到了项目对一体化数据采集仪提出的从远程实现监测现场的可见可记录和可操作等要求，非常适合在危险源场所、安防场所等工业领域应用，具有广阔的市场前景。
[Abstract]:The research project based on this paper is derived from the 2009 project of the Ministry of Science and Technology of the State Ministry of Science and Technology, "Integrated data acquisition instrument for high-risk sites" (Project No. 2009GJE00021).Embedded technology is one of the most vital technologies in the 21st century, and embedded remote desktop control design is an important development direction of digital design under the current network environment.This paper is a combination of safety production applications to remote embedded devices visible?This paper analyzes and studies how to overcome the differences of hardware and transplant remote desktop control function into embedded kernel to support remote users to control remote embedded devices through network.Real-time and convenient access to field data to achieve the purpose of separating the operation from the equipment.Firstly, this paper chooses Windows CE operating system as software platform and S3C6410 microprocessor based on ARM kernel as hardware platform, and designs the hardware and software implementation scheme of the whole remote desktop control system.In the implementation of the scheme, the BSP development based on the S3C6410 hardware platform is studied as the basic and key point, and the source code architecture of the Boot Loader layer is analyzed.The initialization design of Boot Loader, Ethernet port and TFTP connection is completed, so that the operating system can load the Windows CE image through Ethernet, and the design principle of OAL layer is analyzed.The program design and debugging of I / O control interface and serial port for initializing kernel of operating system Kit in OAL layer are completed, so that the Windows CE kernel can communicate with hardware platform interactively, and the buffer structure of Windows CE is analyzed.In order to optimize the cache and improve the efficiency of Windows CE, a four-way group associative design scheme is adopted.Secondly, the device driver is classified, the video driver is designed based on the MDD/PDD model, the audio driver is designed based on the UAM model, and the audio and video information is collected by the embedded device.Then, the kernel customization of remote Desktop Control component in Windows CE system, the loading of wireless communication module, kernel compiling and system startup are completed.Finally, the test environment is built to test and analyze the performance of the whole system.After testing in the server, client and wireless local area network, the system can log in remotely and transfer files remotely.The design of image acquisition and buffer performance has achieved the project of the integrated data acquisition instrument from the remote monitoring of the scene visible?The requirements of recordability and operation are very suitable for industrial applications in hazardous and security areas, and have a broad market prospect.
