基于单片机的脉搏测量系统设计(论文10000字)
摘要：生物医学信号指标与人体的生活健康问题密切相关，只有当人类了解并掌握其中的规则，才能更好地解决社会关注度日益增加的健康问题。随着科学技术水平的发展和现代医学水平的不断进步，人们要求越来越高的精确度和方便快捷的生物医学信号的电子检测设备。心脏速度和体温是反映人体体质的的两个非常重要的指标因此它们具有很高的参考价值。考虑到当代社会的生产发展需要，本次毕设需设计一款基于单片机的脉搏体温检测系统，主要用来监测人体的心率和体温。本设计是基于单片机的脉搏检测系统设计，从可操作性和经济实用性等方面考虑，本次毕业设计采用STC89C52单片机作为系统的芯片，利用Pulsesensor 脉搏传感器作为心率的采集模块；而体温的采集则使用DS18B20温度传感器。脉搏波和体温在指尖或耳垂采集，采集的信号经单片机滤波、信号放大等处理后，输出给液晶显示模块显示最终结果。

Design of Pulse Measurement System Based on Single Chip Microcomputer
Abstract：Biomedical signal indicators are closely related to people health problems. Only when human understand and master the rules, can we better solve the growing health problems of social concern. With the development of science and technology and the continuous progress of modern medicine, people require more and more accurate and convenient electronic detection equipment for biomedical signals. Heart speed and body temperature are two very important indicators reflecting human body constitution, so they have high reference value. Considering the production and development needs of the contemporary society, this design needs to design a pulse temperature detection system based on single-chip computer, which is mainly used to monitor the heart rate and body temperature of the human body.This design is based on the design of pulse detection system of single-chip computer. Considering the operability and economic practicability, this graduation design uses STC8952 single-chip computer as the chip of the system, pulse sensor as the heart rate acquisition module, and DS18B20 temperature sensor as the temperature acquisition module. Pulse and body temperature are collected at fingertips or earlobes. The collected signals are filtered and amplified by a single chip computer, and then output to the LCD module to display the final results.
Key words: MCU; Heart Rate Sensor; Body Temperature Measurement; LCD Display.
