基于单片机的电子体温计设计
摘要
智能控制是近年来发展起来的一门综合学科,集中了机械、电子、计算机、自动控制、无线传
感、传感器融合以及人工智能等多学科的最新研究成果,代表了机电一体化的最高成就。近年来,
智能控制和智能检测人已经成为自动化、计算机和人工智能等领域的一个研究热点。和传统的监测
和控制系统相比,具有自主感知、决策和执行功能的智能监测控制系统具有广阔的应用前景。目前,
单片机技术以其低复杂度、低成本、低功耗等优点,被广泛地应用于智能监测和控制系统中。
本文以人体温度监测系统为研究对象,使用单片机设计了人体温度监测系统,并给出了设计框
图、硬件组成及软件系统。本系统以 51 单片机最小系统为核心,主要的部件有 AT89S51 单片机、
DS18B20 温度传感器、液晶显示屏 LCD1602、蜂鸣器等。系统通过 DS18B20 对人体的温度信号信
号进行采集,经过单片机对探测结果经过去噪和识别之后,根据系统预设温度阈值,对异常温度进
行蜂鸣器报警。整个系统有监测准确度高、实时性好、成本低得优点。

Abstract
Intelligent control is a comprehensive subject developed in recent years, focus on the mechanical,
electronic, computer, automatic control, wireless sensor, sensor fusion, and the latest research results of
many subjects such as artificial intelligence, represents the highest achievement of electromechanical
integration. In recent years, intelligent control and intelligent monitoring has become a human in areas such
as automation, computer and artificial intelligence a research hot spot. Compared with the traditional
monitoring and control system, which has the function of autonomous perception, decision-making and
implementation of intelligent monitoring and control system has broad application prospects. At present,
single-chip microcomputer technology with its advantages of low complexity, low cost, low power
consumption, is widely used in intelligent monitoring and control system.
In this paper, the body temperature monitoring system as the research object, the body temperature
monitoring system using single-chip microcomputer, and presents the design block diagram, hardware
composition and software system. This system with 51 single chip microcomputer minimum system as the
core, the main components are AT89S51, DS18B20 temperature sensor, LCD display LCD1602, buzzer,
etc. Through DS18B20 the temperature of human body system signal acquisition, signal by single-chip
computer for detecting results after denoising and identification, based on the system default threshold
temperature, buzzer alarm for abnormal temperature. Monitoring the system to have high accuracy and
good real-time performance, low cost advantages.
