【摘要】：随着计算机技术和无线网技术的日益成熟,嵌入式设备已经深入到人们生活的各个领域。如远程监控设备、视频服务器等。这些设备的最主要目的在于满足实时数据传输的需求以及一些控制功能。嵌入式系统可从规模、时限、网络能力、与用户交互几个方面来分类。本课题主要研究基于ARM+Linux的嵌入式系统的驱动及应用程序开发。并结合几个开发实例来具体阐述嵌入式系统的开发流程及系统设计。其中无线图像接收机控制器主要是通过以太网来对无线图像接收设备进行控制。而基于ARM11的车载广告系统则主要是研究用于车载的多媒体设备。 论文的研究内容主要包括采用MFC的用户界面设计,嵌入式Linux系统下的并发服务器的开发,以及设备驱动程序的开发。在车载广告系统中,采用的技术主要有GPS定位技术,Wi-Fi无线通信技术,在Linux的V4L2架构下,完成对音视频文件的处理,并且针对系统需求对MPEG-4媒体文件格式进行了手动解析,使得可以对视频信息和音频信息分别进行解码,并且实现了音视频的同步。
[Abstract]:With the increasing maturity of computer technology and wireless network technology, embedded devices have penetrated into every field of people's life. Such as remote monitoring equipment, video server and so on. The main purpose of these devices is to meet the demand of real-time data transmission and some control functions. Embedded systems can be classified in terms of scale, time limit, network capability, and interaction with users. This paper mainly studies the driver and application development of embedded system based on ARM Linux. The development process and system design of embedded system are elaborated with several development examples. The wireless image receiver controller mainly controls the wireless image receiving device through Ethernet. The vehicle advertising system based on ARM11 is mainly used for vehicle multimedia equipment. The main contents of this paper include the design of user interface using MFC, the development of concurrent server under embedded Linux system, and the development of device driver. In the vehicle advertising system, the main technologies are GPS positioning technology and Wi-Fi wireless communication technology. Under the V4L2 framework of Linux, the audio and video files are processed, and the format of MPEG-4 media files is manually analyzed according to the requirements of the system. So that video and audio information can be decoded, and achieve audio and video synchronization.
