基于AT89S51单片机的电子血压计设计

Design of Electronic Blood Pressure Monitor Based on AT89S51MCU

针对采用传统单片机的电子血压计成本高、测量精度低等缺点,以AT89S51单片机为控制核心,采用气体压力传感器US9111、串行A/D转换芯片ADC0832、LCD驱动芯片和外围模拟电路设计了新的电子血压计,并采用C语言编程.所设计的血压计具有成本低、测量精度高等优点.

The disadvantages of traditional design of MCU lie in high cost, as well as the poor accuracy. Based on the mechanism of measurement of blood pressure, this paper designs an electronic blood pressure monitor, which uses AT89S51MCU,air press sensor US9111, serial A/D transfer chip ADC0832, LCD module and analogy circuit as the hardware, and the software is written in C language. The designed blood pressure monitor is low in cost and more accurate. We hope that it will have a potential application in the near future.
