基于 51 单片机的电子血压计设计

摘要：人体健康基本指标之一是血压，当今高血压病发病率。有了高血压病需要长期观察血压的

情况，来调整自身用药。血压需要用血压计测量，传统的一些血压计已经不能满足我们日常生活

的系需求。本论文设计一个基于 51 单片机的血压计，便于医疗和家具使用。是测量血压跟价快

捷方便，走入家庭化和大众化，让更多人得到多一份健康。

本文首先分析了因为各种原因导致高血压，使高血压病变得普遍化，而传统的一些测量血压

的方法不能满足广大高血压患者的使用，所以设计出一款基于 51 单片机的血压计。让价格更加

便宜，使用更加方便可靠。

其次本文再从整体设计中讲述了 51 单片机血压的设计方案。再详细描述了对本设计的元器件的

Abstract：One of the basic indicators of human health is blood pressure, the current incidence of

sphygmomanometers can no longer meet the needs of our daily lives. This thesis designs a

sphygmomanometer based on 51 single-chip microcomputer, which is convenient for medical and

furniture use. It is fast and convenient to measure blood pressure and price. It has become family and

popular, so that more people get more health.

This article first analyzes the high blood pressure caused by various reasons, which makes the

hypertension universal, and some traditional methods of measuring blood pressure can not meet the

needs of the majority of patients with high blood pressure, so a sphygmomanometer with a 51 MCU is

designed. Make the price cheaper, more convenient and reliable to use.

Secondly, this article describes the design scheme of 51 single-chip blood pressure from the overall

design. It then describes in detail the selection of the components of this design, explains the relevant
