摘要
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.
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.
