基于C8051F330便携式生理参数监测仪设计

随着人们生活水平的提高，越来越多的人希望通过简便的方式了解身体基本状况。因此人体生理监护仪开始出现并呈不断增多的趋势，已经由过去的单一测试仪发展为现在的多参数监护仪。在实际生活中，生理参数监测仪多是基于PC机平台的多参数测量、价格昂贵、体积庞大、不便于移动。现在多数生理参数监测仪无法准确的实时测量人体运动时的生理参数，导致有些人特别是老年人运动强度过大，对身体造成较大伤害。而教练员因无法准确掌握运动员运动时生理参数变化，而不能“因材施教”，有针对性的制定训练方案，所以运动员训练方式都是大众化训练。综上所述，开发一种体积小、价格低，基于嵌入式系统的便携式生理参数监测仪就具有重要的意义。 1 系统方案本系统采用C8051
