数字血压计的设计【毕业论文，绝对精品】.doc

摘要 伴随着现代社会的快速发展，我们的生活水平不断提高，但是由于不健康的生活习性与不科学的饮食习惯，导致人们很容易产生各种各样的疾病。而高血压作为其中的一种，已经成为威胁现代人健康的第一杀手，它使得越来越多的人饱受病痛的折磨。如何方便有效的测量与监控高血压，从而有效的预防与治疗高血压，成为人们对抗高血压病的首要问题。于是，设计出一台简单的血压测量装置成为解决这一问题的最直接方法。数字血压计是一种简单的测量血压的装置，作为家庭医疗保健的一种，它可以便捷有效的在家里随时监测血压的变化，如果发现血压的异常现象就可以及时去医院进行治疗，从而起到及早预防疾病的作用。 本次毕业设计完成了对数字血压计的设计，并实现了对人体血压进行测量的功能。设计包括硬件和软件两部分，其中硬件部分主要有感应模块、处理模块和显示模块三部分。感应模块采用ASDX001作为数字传感器，将血压信号转换为数字信号；处理模块采用AT89C51单片机对信号进行处理；显示模块采用DM-1602液晶显示屏显示测量结果。软件部分主要主要包括测量模块、数据处理模块、显示模块等几部分。测量模块对传感器信号进行测量与放大；数据处理模块对接收的传感器信号进行计算与处理；显示模块将最后的数据处理结果通过显示器显示。最后，通过血压测量实验证明了数字血压计的有效性。 关键词：血压测量；ASDX001；AT89C51；LCD显示；  Abstract With the developing of the modern society, the quality of our life has been improved quickly. However, more and more people are suffering from various kinds of diseases which are results of unhealthy lifestyles and eating habits. High blood pressure is a disease among them. In order to help people stay away from high blood pressure, we need to find an efficient way to measure and monitor blood pressure. And that is where the idea of designing a simple device to measure blood pressure comes from. Digital blood pressure meter is a simple blood pressure measure device. As a member of family health care devices, it can be used at home at any time. Since it is convenience and sensitivity, it can help people to control their blood pressure and go to the hospital on time. The completed design of digital blood pressure meter design，and realization of human blood pressure measuring function. The work can be divided into hardware design and software design. The hardware includes induction module，processing module and display module etc. The ASDX001 digital sensor is adopted into the induction module to transfer the blood pressure signal into the digital signal. AT89C51 SCM is used in the processing module to process the signal. The measurement results are shown in the DM-1602 LCD screen by the display module. The software includes measurement module, data processing module, display mo
