【摘要】：近几十年来科学技术得到了飞速的发展，CPU技术已由单核高频时代迈入了多核多线程时代，类似云端计算、云存储、并网计算、多线程下载等新型技术不断涌现。随着近年来物联网技术的出现和快速扩张，嵌入式技术得到了广泛的关注和发展。智能、节能、高效成为了当下时代科技发展的主题。嵌入式系统具有功耗低、体积小、成本低等优点，它的特点很符合当前科学技术发展的潮流。嵌入式技术的出现，使得更多的单片机功能正在被嵌入式技术所取代。嵌入式技术带有强大的处理器，能够处理单片机所不能达到的速度和稳定性，并且它搭载操作系统，能够进行实时反馈，可以进行多任务运行。为了适应物联网技术的发展需求，构造一款以嵌入式处理器为核心并且搭载操作系统的智能安防监控系统是一次顺应时代发展的尝试。本文基于ARM9与Linux系统设计了一款多功能的安防监测平台系统，当下主流的安防监控系统多采用单片机控制实现，，稳定性已经满足不了时下的需求，更加不能适应物联网技术的发展需求。本文通过搭建开发平台、移植、测试几个主要部分，结合软硬件设计开发了一款基于ARM与Linux的多功能安防监测平台。主要工作包括：从虚拟机的选择，Fedora系统的安装配置，到如何构建主机、宿主机、板载三方之间的通信这几个方面搭建了一个完善的嵌入式开发平台系统；然后进行了大量的交叉编译和移植的工作，主要包括了内核的编译移植，bootloader的交叉编译移植，根文件系统的制作；以及应用程序的移植，主要包括：DHCP、motion、ffmpeg、SDL、Boa、ds18b20驱动等。主要实现温度和视频的实时监控，以及无人看守警报监控等功能。通过基本测试，虽然各个方面的稳定性和协调性还有待改进，但是在通过嵌入式进行智能安防监控警报方面仍不失为一个很好的尝试，有望在进行更好的优化和改进后能够得到很好的推广。
[Abstract]:In recent decades, with the rapid development of science and technology, CPU technology has entered the multi-core multi-thread era from the single-core high-frequency era, such as cloud computing, cloud storage, network-connected computing, multi-thread download and other new technologies have been emerging. With the emergence and rapid expansion of the Internet of things technology in recent years, embedded technology has been widely concerned and developed. Intelligence, energy-saving and high efficiency have become the theme of the development of science and technology in the present era. Embedded system has the advantages of low power consumption, small size and low cost. With the emergence of embedded technology, more MCU functions are being replaced by embedded technology. Embedded technology has a powerful processor, which can deal with the speed and stability that can not be achieved by a single chip, and it is equipped with an operating system, which can carry out real-time feedback and multitask operation. In order to meet the needs of the development of the Internet of things, it is an attempt to construct an intelligent security monitoring system based on embedded processor and operating system. This paper designs a multi-function security monitoring platform system based on ARM9 and Linux system. The current mainstream security monitoring system is realized by single-chip microcomputer control, and the stability can not meet the current needs. Not to meet the needs of the development of Internet of things technology. In this paper, a multi-function security monitoring platform based on ARM and Linux is developed by building a development platform, transplanting, testing several main parts and combining software and hardware. The main work includes: from the choice of virtual machine, the installation and configuration of Fedora system, to how to build host, host and communication between the three parties, a perfect embedded development platform system is built; Then a large number of cross-compilation and transplantation work, mainly including the kernel compilation and transplantation, bootloader cross-compilation and transplantation, root file system production; And application porting, including: DHCP,motion,ffmpeg,SDL,Boa,ds18b20 driver and so on. Mainly realizes the temperature and the video real-time monitoring, as well as the unattended alarm surveillance and so on function. Through basic testing, although the stability and coordination of all aspects need to be improved, it is still a good attempt to carry out intelligent security monitoring and alarm through embedded system. It is expected to be well promoted after better optimization and improvement.
