摘要
介绍一种基于USB接口的多道生理信号采集系统的软硬件结构原理和实现方法。该系统可以实现心电、血压、血氧饱和度、呼吸、体温5个参数的采集和记录。系统操作方便、灵活。
This paper introduces the structure and implementary method both in hardware and software of a multi-channel physiological signal acquisition system based on USB interface. The parameters collected by the system include electrocardiogram (ECG), blood pressure (BP), oxygen saturation (SpO2), respiration and body temperature. The system has advantages of easy operation and flexible structure.
