摘要
提出一种新型的胎心率处理方法——利用自相关技术和模糊技术的模糊计数器,用于处理由于胎心率多谱勒信号变异和干扰增强导致心率增加或者漏减的现象。在基于DSP的检测系统中证明该系统具有鲁棒性高的系统检测水平和良好的临床应用水平。
The paper presents a novel fetal heart rate（FHR）detecting system which is a fuzzy counter using the auto-correlation and fuzzy mathematic algorithm.This system is able to deal with the increase and decrease phenomena of FHR,caused by the various interference and noises.It has a higher detection level than ever and a better robust system based on the DSP.
