基于MEMS技术和无线射频网络的人体健康参数采集系统

Human Health Parameters Acquisition SYSTEM Based on MEMS and Radio Frequency Network

结合MEMS技术和无线射频技术,提出了一种新型的人体健康参数采集方法.基于此方法设计了一种便携式、低成本的人体健康参数采集系统.介绍了系统的测量原理以及硬件和软件设计.该系统测量体温的精度为±0.5℃,测量血压的精度为±1mmHg,在可靠通讯距离下无线数据传输的实际乱码为0.

This system integrates MEMS and radio frequency technique together, and puts a new method forward on the acquire of human＇s health parameters. Based on this method, a portable human＇s health parameters acquiring system with low cost was designed. This paper introduces the acquiring theory and the design of software and hardware that employed in the system. The precision in body heat measure is ±0. 5℃ and in blood pressure measure is ±1 mmHg. Within an effective communication distance, the practical rate of inaccuracy of wireless transmission is 0%.
