摘　　要：本文介绍了一种采用示波法进行测量的电子血压计设计，该系统以美国TI公司的MSP430F449单片机为控制核心。应用仪表放大器INA128对微小信号进行放大，通过LM324对信号进行滤波调理，采用幅度系数法确定舒张压和收缩压的时间位置，辅以串口通信和时钟控制等功能芯片，较好地实现了对血压的准确测量。This paper presents the design of an electronic blood pressure meter with oscillography. It adopts a single-chip microcomputer MSP430F449 manufactured by American TI Company as the control kernel. Firstly the tiny signal is amplified by the special chip INA128, and then, the amplified signal is filtered and conditioned by the OP amp LM324. The time and location of the diastolic pressure and systolic pressure is determined with the amplitude coefficient method, assisted with the serial and clock control chips, the system has realized accurate measurement of blood pressure.
