基于嵌入式LINUX的远程土壤信息采集系统设计

Design of Soil Parameter Wireless Remote Collection and Transmission System Based on Embedded Linux

针对大范围分散的农田信息采集中采集系统通讯成本已大大高于测控部分的成本和通讯已成为制约农田数据采集发展和应用的问题,提出了一种基于嵌入式LINUX操作系统下用TC35I无线通信模块实现远程土壤信息采集系统的设计方案,详细阐述了系统的硬件组成、土壤信息数据采集及传输的通信原理和嵌入式系统Web的构建。实验结果表明,系统能够及时接受远程数据并将数据发送和显示,通过网络实现了对远程采集终端的控制,达到了系统的设计要求。

For the information collection in the large scale and disperse area,the expend of communication is much higher than measure and control＇s.Therefore,communication has became the main obstacle for the development of the information collection of farmland.This thesis introduced a design scheme of remote and wireless soil＇s information collection system which is based on ARM9,embedded Linux and TC35i GSM Module.The hardware,theory of wireless soil parameter collection and transmission,and the construction of embedded web are introduced particularly.The result of experiment indicate that this system can receive remote information and show it on the Web exactly and timely,and realized the terminal＇s remote control by Internet,and reached the requirement of the primary plan.
