毕业论文-基于单片机的电子体温计设计.docx

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。关键字：单片机；温度监测；DS18B20；阈值报警；LCD1602The design of electronic thermometer based on SCMElectronic Information Science and Technology 11-1 Yin YueSupervisor Zhang QianAbstractIntelligent 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
