基于单片机体温检测仪系统的设计与实现PAGE \* MERGEFORMATIV基于单片机体温检测仪系统的设计与实现PAGE \* MERGEFORMATIIn this paper, a temperature detection system based on a single-chip microcomputer is designed to detect human body temperature, display it in digital form, and play the detected human body temperature specific value through the mode of voice playback.The system is composed of several parts: SCM, sensor, LCD, and voice module. The hardware structure is designed with the microcontroller STC89C52 as the core. It detects the human body temperature through the temperature sensor DS18B20, displays the human body temperature value on the LCD1602, and then plays the detected value through the voice module. . Part of the system software through the software keil C language program development and design, debugging.The designed electronic body temperature detector has realized temperature detection, digitization, and electronization, which is of great help to the development of future thermometers. The electronic thermometer can gradually replace mercury (toxic element) thermometers, which greatly improves the use value of thermometers, makes readings clear, and reduces Human body damage, safety and environmental protection have further improved the smart life of people.Keywords: Body temperature detector; Electronic; STC89C52 microcontroller;LCD1602目录TOC \o 1-3 \h \u HYPERLINK \l _Toc7546 摘要 PAGEREF _Toc7546 I HYPERLINK \l _Toc12369 Abstract PAGEREF _Toc12369 II HYPERLINK \l _Toc14811 目录 PAGEREF _Toc14811 III HYPERLINK \l _Toc10559 1 绪论 PAGEREF _Toc10559 1 HYPERLINK \l _Toc121 1.1 背景 PAGEREF _Toc121 1 HYPERLINK \l _Toc28236 1.1.1 项目背景 PAGEREF _Toc28236 1 HYPERLINK \l _Toc24383 1.1.2 国内发展状况 PAGEREF _Toc24383 1 HYPERLINK \l _Toc24139 1.1.3 项目研究内容和要求 PAGEREF _Toc24139 2 HYPERLINK \l _Toc10220 2 系统分析与设计 PAGEREF _Toc10220 3 HYPERLINK \l _Toc367 2.1 系统分析 PAGEREF _Toc367 3 HYPERLINK \l _Toc29090 2.1.1 系统流程 PAGEREF _Toc29090 3 HYPERLINK \l _Toc2826 2.2 概要设计 PAGEREF _Toc2826 3 HYPERLINK \l
