基于MSP430F149单片机的低功耗电子血压计设计

摘要

In this paper,a low-power electric sphygmomanometer based on MSP430F149 is introduced,which consists of data acquisition module,control circuit of air pump and release valve module,power supply module,stored module and displayed module.The blood pressure signal is real-time sampled by US9116-006-N,it was converted to digital signal and processed by MSP430F149.The system which is low-power and portable can real-time measure,display and store blood pressure.%介绍一种基于MSP430系列单片机的低功耗电子血压计。该系统以MSP430F149单片机为核心,由数据采集模块、气路控制模块、电源模块、存储模块和显示模块等模块电路组成。通过US9116-006-N压力传感器实时采集压力信号,由MSP430F149对采集到的信号进行A/D转换和分析处理得到血压值,同时将结果进行显示和存储。该系统具有低功耗和携带方便等优点。
