Design of electronic blood pressure meter based on MSP430

针对传统电子血压计的不足,介绍了一种基于超低功耗单片机的全自动血压测量系统的设计方案,测量血压的方法是基于充气过程的示波法。该测量系统采用MSP430系列超低功耗混合信号处理器作为核心处理器,采用幅度系数算法计算出血压值和心率值,可以完成自动测量血压、信息显示、数据存储、查看和删除历史数据等功能。由于采用了MSP430混合信号处理器,简化了电路的设计,提高了系统的可靠性和稳定性。实际应用表明,该系统具有操作简便、测试准确的特点。

A design of full-automatic electronic blood pressure meter based on ultra-low power MCU is introduced against the shortcomings of previous digital blood pressure meterin this paper. The method of measuring blood pressure is the oscillometric method during inflating process. The system uses MSP430 series ultra low power consumption mixed signal MCU as the core processor, amplitude coefficient algorithm used to calculate the value of blood pressure and heart rate values. The blood pressure monitor automatic blood pressure measurement to be completed, information display, data storage, review and delete the historical data and other functions. As a result of using MSP430 series ultra low power consumption mixed signal MCU, it simplifys circuit design, improves reliability and stability. The experiment and application show that this test system has good performance, and achieve the design requirement.
