【摘要】：隨著信息技術(shù)的飛速發(fā)展和廣泛應(yīng)用，農(nóng)田信息監(jiān)測的方法和手段在不斷提高和豐富，但總體來看，農(nóng)田信息監(jiān)測系統(tǒng)仍存在一些有待解決的問題。農(nóng)田具有分布散、布線難、設(shè)備多、傳輸距離有限、現(xiàn)場信息復(fù)雜、設(shè)備難管理的特點，隨著3S技術(shù)在現(xiàn)代農(nóng)業(yè)中的廣泛應(yīng)用，影響農(nóng)作物生長的信息參數(shù)種類、采集區(qū)域、數(shù)據(jù)精度的要求也逐漸增加，僅依靠傳統(tǒng)農(nóng)業(yè)方式，采用單片機數(shù)據(jù)采集監(jiān)測系統(tǒng)很難達(dá)到當(dāng)今農(nóng)業(yè)監(jiān)測系統(tǒng)的高標(biāo)準(zhǔn)要求。 ARM作為嵌入系統(tǒng)設(shè)計的通用處理器內(nèi)核，具備高性能、低功耗、易擴展的優(yōu)點，逐漸被應(yīng)用到各個領(lǐng)域，農(nóng)業(yè)嵌入式服務(wù)器也逐漸成為一種發(fā)展趨勢。本文設(shè)計了一種基于ARM嵌入式技術(shù)的農(nóng)田信息監(jiān)測系統(tǒng)服務(wù)器設(shè)計方案。農(nóng)田信息服務(wù)器，選擇以ARM920T為核心的三星S3C2440為硬件系統(tǒng)的處理器平臺，以嵌入式Linux為操作系統(tǒng)，對采集到的農(nóng)田信息進(jìn)行可靠傳輸和管理，方便用戶對農(nóng)田管理做出科學(xué)決策，系統(tǒng)具有良好的穩(wěn)定性和擴展性。 本論文的主要研究內(nèi)容包括： （1）分析了國內(nèi)外農(nóng)田信息監(jiān)測系統(tǒng)的現(xiàn)狀，，討論了課題研究背景和意義，總結(jié)出基于ARM嵌入式技術(shù)的農(nóng)田信息監(jiān)測系統(tǒng)的發(fā)展方向和趨勢。 （2）對ARM處理器的體系結(jié)構(gòu)、嵌入式操作系統(tǒng)和系統(tǒng)開發(fā)的關(guān)鍵技術(shù)進(jìn)行了深入研究，進(jìn)行了系統(tǒng)的總體設(shè)計。 （3）實現(xiàn)了bootloader移植，Linux內(nèi)核的定制，文件系統(tǒng)的編譯及移植，嵌入式圖形開發(fā)環(huán)境QT的移植等。 （4）實現(xiàn)了嵌入式服務(wù)器與無線傳感器網(wǎng)絡(luò)之間的通信，并設(shè)計相應(yīng)通信數(shù)據(jù)幀。通過TCP/IP實現(xiàn)了嵌入式服務(wù)器與系統(tǒng)應(yīng)用層之間的通信。 （5）在搭建的嵌入式軟硬件平臺上實現(xiàn)嵌入式Web Server，完成相關(guān)配置。開發(fā)設(shè)計CGI程序并實現(xiàn)動態(tài)Web技術(shù)，以此來實現(xiàn)與用戶的交互功能。
[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.
