摘要
本文用相关函数理论的基本原理,以三托辊电子皮带秤为研究对象,分析了皮带秤测速系统的机制。其中,以称重传感器信号作为输入量,解决了三个托辊受力情况下,采样信号与相关分析所需信号之间的数学关系。建立了恰当的数学模型,并分析了它独特的优点。
The measuring speed system mechnics of electronic belt scale is analysed by using correlation function theory. On condition that three idlers are forced, the mathematical relationship between sampled signals and correlated signals are determined and the proper mathematical model is built up. Features of the model are also analysed.
