【摘要】 本文从解决传统农田数据采集系统功能单一、远程无线遥控困难等实际问题出发,在仔细研究国内外现有的几种农田数据采集系统的基础上,深入研究项目任务书和走访该系统的终端用户,提出了一种基于嵌入式系统技术的最优化实现方案,并对此种方案的设计思路、性能特点和适用范围等进行了详细的论证。本文采用嵌入式系统技术,通过软硬件协同开发,构建了以ARM处理器S3C44B0为核心、嵌入式实时操作系统μC/OS-II为操作系统的开发平台,实现了基于GSM网的远程无线数据传输和远程无线控制等功能和基于FATFS文件系统的CF卡海量数据本地存储等功能。该系统的研制成功,能够高精度地、实时地采集田间影响农作物生长的环境信息,从而为农业生产的科学决策提供数据保证;本系统的最大特点是无人值守,降低了农田环境信息采集、传输和控制的成本;丰富了传统的数据采集装置的功能,达到了一机多用的目的。通过实践证明基于嵌入式微处理器的多功能的采集系统满足了农业生产需要,达到了预期目标,是一种行之有效的农田数据采集传输方案。更多还原

【Abstract】 The traditional field data acquisition set is single in functions and difficult to control with remote wireless method.To solve these problems,the paper researched the design assignment of project and the need of end users,and put forwad an optimization method based on embedded system technology,the demonstration of thoughts,features and application sphere was embodyied in this paper.The paper adopt the embedded system technology by the way of software and hardware joint-designing,structure a platform with the ARM CPU named S3C44B0 and RTOSμC/OS-II,realize the functions such as remote wireless transmit, remote wireless control and mass data storage with CF card based on FATFS.This system could Accurately and real-time collecting the farm environment information land which effect the growth of crops,So it can supply the Scientific Decision-Making sufficient data.The unattended operation is a key feature of this system,and it could reduce the cost of collecting,transmitting,storing the information and controling the system.The success enrich the functions of traditional set,reach the all in one design aim.Actual practice proves that the multifunction farm information acquisition based on embedded system technology was a feasible proposal.It has meet the need of farm practice, satisfied the re-set targets.更多还原
