摘要
提出一种基于MCU单片机的纹波电压采集分析系统,为了达到从微观上对纹波电压分析的目的,采用以STC89C54为控制核心,以Matlab为分析工具,应用层次化、模块化主导思想,融入了数据采集、数据交换、数据处理等多种关键技术,完成纹波信号的采集试验,得到系统分析所需研究数据,对未知纹波信号进行还原,并通过后期数据处理,了解纹波电压的存在情况,实现对纹波信号的测试与分析。该系统在以往单一测试或分析的基础上,把测试与分析融为一体,使纹波的研究工作又向前迈进一步。
In order to analyze the ripple voltage from the microcosmic point of view, a ripple voltage acquisition and analysis system is presented in this paper. The system with STC89C54 as the control core and the Matlab as the analysis tool is integrated with the key technologies of data acquisition, data exchange and data processing based on the hierarchical and modular dominant ideology to implement the ripple signal acquisition and obtain the research data required by the analysis system. The unknown ripple signals are restored and processed in the late phase to realize the ripple signal test and analysis. On the basis of the current sigle test or analysis method, the proposed system integrates data test with data analysis and thus the research on the ripple makes great progress.
