摘要
结合80C196KC单片机交流采样系统,着重分析了影响半波付里叶算法精度的各种因素,并在交流采样算法、测频、采样步长划分、采样同步、单片机A/D转换、抗干扰以及参数计算等方面提出了改进,给出了实用的硬件图和软件流程图。
Based on 80C196KC single-chip microprocessor AC sample system,this paper especially analyses various factors that influence the precision of Half-cycle Fournier Arithmetic,makes improveme nt on many ways such as arithmetic,frequency measure, sample step partition, sam ple synchronization, A/D conversion, anti-jamming and parameter calculation,an d finally provides applied hardware chart and software flow chart.
