介绍了一种基于STC12LE5410AD微控制器的便携式自主神经功能数据采集仪的设计.包含心电信号放大及AD转换电路.采用SD卡作为存储介质.记录时间较长.并且可方便地向PC机转移数据.结构简单.实现了系统的小型化和低功耗。
In this paper, a design of the portable acqusition system for autonomic nervous function data based on the microcontroller is introduced. The system contains an electrocardiogram amplifier and an AD convertor, using SD memory card as its storage device and thus it can record data for a longer time and exchange data with PC easily. The system with a simple structure realizes its miniatudzation and low energy consumption.
