【摘要】：随着信息技术的飞速发展和广泛应用，农田信息监测的方法和手段在不断提高和丰富，但总体来看，农田信息监测系统仍存在一些有待解决的问题。农田具有分布散、布线难、设备多、传输距离有限、现场信息复杂、设备难管理的特点，随着3S技术在现代农业中的广泛应用，影响农作物生长的信息参数种类、采集区域、数据精度的要求也逐渐增加，仅依靠传统农业方式，采用单片机数据采集监测系统很难达到当今农业监测系统的高标准要求。 ARM作为嵌入系统设计的通用处理器内核，具备高性能、低功耗、易扩展的优点，逐渐被应用到各个领域，农业嵌入式服务器也逐渐成为一种发展趋势。本文设计了一种基于ARM嵌入式技术的农田信息监测系统服务器设计方案。农田信息服务器，选择以ARM920T为核心的三星S3C2440为硬件系统的处理器平台，以嵌入式Linux为操作系统，对采集到的农田信息进行可靠传输和管理，方便用户对农田管理做出科学决策，系统具有良好的稳定性和扩展性。 本论文的主要研究内容包括： （1）分析了国内外农田信息监测系统的现状，，讨论了课题研究背景和意义，总结出基于ARM嵌入式技术的农田信息监测系统的发展方向和趋势。 （2）对ARM处理器的体系结构、嵌入式操作系统和系统开发的关键技术进行了深入研究，进行了系统的总体设计。 （3）实现了bootloader移植，Linux内核的定制，文件系统的编译及移植，嵌入式图形开发环境QT的移植等。 （4）实现了嵌入式服务器与无线传感器网络之间的通信，并设计相应通信数据帧。通过TCP/IP实现了嵌入式服务器与系统应用层之间的通信。 （5）在搭建的嵌入式软硬件平台上实现嵌入式Web Server，完成相关配置。开发设计CGI程序并实现动态Web技术，以此来实现与用户的交互功能。
[Abstract]:With the rapid development and wide application of information technology, the methods and means of farmland information monitoring are continuously improved and enriched. However, in general, there are still some problems to be solved in the farmland information monitoring system. Farmland has the characteristics of scattered distribution, difficult wiring, many equipments, limited transmission distance, complex field information and difficult management of equipment. With the wide application of 3s technology in modern agriculture, the types of information parameters affecting crop growth and the collection area are discussed. The requirement of data precision is increasing gradually. It is difficult to meet the high standard requirement of agricultural monitoring system by using single chip microcomputer data acquisition and monitoring system only on the traditional agricultural mode. As a general processor kernel of embedded system design, ARM has the advantages of high performance, low power consumption and easy to expand. It has been gradually applied to various fields, and agricultural embedded servers have gradually become a trend of development. This paper designs a server design of farmland information monitoring system based on ARM embedded technology. The farmland information server chooses Samsung S3C2440, which is the core of ARM920T, as the processor platform of the hardware system, and uses embedded Linux as the operating system to reliably transmit and manage the collected farmland information, so as to facilitate users to make scientific decisions on farmland management. The system has good stability and expansibility. The main contents of this paper are as follows: (1) the present situation of farmland information monitoring system at home and abroad is analyzed, and the research background and significance are discussed. The development direction and trend of farmland information monitoring system based on ARM embedded technology are summarized. (2) the architecture of ARM processor, the embedded operating system and the key technology of system development are deeply studied, and the overall design of the system is carried out. (3) implement bootloader transplantation, customization of Linux kernel, compile and transplant of file system, transplant of embedded graphics development environment QT, etc. (4) the communication between embedded server and wireless sensor network is realized, and the corresponding communication data frame is designed. The communication between the embedded server and the application layer of the system is realized by TCP/IP. (5) implement the configuration of embedded Web Server, on the platform of embedded software and hardware. Develop and design the CGI program and implement the dynamic Web technology to realize the interactive function with the user.
