一种基于USB2.0协议的人体生理信息采集系统设计

介绍了一种实用的人体生理信息采集系统的研究与设计，介绍了人体生理信息的分类及常用采集方式，以及生理信息采集系统的软、硬件组成，并给出了实验演示的结果．实验证明，这种生理信息采集系统对于生理小信号具有较好的信号放大、AD转换和数据采集功能，并能在PC机上正确显示生理信号波形，具有较好的实用性和发展前景．

Design of physiologic information collection system based on USB2.0 protocol

The design of a practical physiologic information collection system is presented. First, the classification of the physiologic information and the conventional information collection methods are introduced; then the whole system with software and hardware modules are proposed; at last, the experiment result is shown. The experiment proves that the physiologic information collection system has excellent function in signal magnification, AD conver- sion and data collection, and can exactly display the physiology signal wave in PC . This system has good practicability and development prospect.
