基于过采样技术提高农田数据采集精度的研究

Study on improvement of accuracy of field data collection methods based on oversampling technology

在农田数据采集恶劣环境下,ADC转换时可能引入很多种噪声,从而使采集装置性能变差.基于过采样技术,提出一种可以有效地提高分辨率,显著提高采集精度和抗干扰能力的A/D转换新方法,紧密结合实际讨论了运用过采样技术设计数据采集单元的相关问题.

In the field of data collection in harsh environments, ADC conversion may intro- duce a variety of noise, so that the acquisition device performance variation. Over-sampling- based techniques, this paper proposed an effective method to improve the resolution significantly improve the accuracy and performance, acquisition of A/D conversion of new methods, in turn, discussed the close connection with the actual use of oversampling design issues related to data acquisition unit.
