摘要
介绍了便携式单导联心电记录仪的工作原理及性能特点,具体分析了各部分的组成及原理.解决了大容量数据的无损压缩与存储,实现了LCD的实时显示和冻结显示,并建立了单片机与PC机的数据传送,使进一步分析心电图更加方便.
Through the analysis to the theory and characteristics of pocket one-wire linked electrocardiograph, this paper puts forward the composition and fundamentals of all parts. Large capacity of undamaged compression of mass data and storage is solved and this makes it possible for LCD抯 real-time display and freeze display. The data transfer of single chip computer and PC-computer is realized. As a result, it is more convenient to analyze electrocardiogram.
