摘要
针对精细农业中实时数据采集问题,将数据采集技术与嵌入式技术相结合,以PHILPS公司生产的LPC2214微控制器为核心,并辅以外围芯片和接口电路,设计了一个基于LPC2214微控制器的嵌入式数据采集系统,可实现对8路数据进行可变采样频率的采集。实验证明,基于嵌入式系统的田间信息采集系统具有较强的可靠性与抗干扰能力。
Aiming at the problem of the data collecting in the research of agriculture precision agriculture.An embedded data collecting system based on LPC2214 is designed,In this system technique of embedded is combined with technique of data acquisition. LPC2214 of PHILPS Company is combined with other circuits and interfaces,so that it can do 8 channel data acquisition and the sample-frequency is variable.The system works reliable and its anti-interference is strong.
