PAGE \* MERGEFORMAT PAGE \* MERGEFORMAT I非接触式红外测温仪的设计摘 要利用温度测量技术是很常见的，而且在当前问题的检测设备类仍然是一个非常重要的技术。但在某些应用中，需要使用测量与被测物体接触式温度传感器，它需要一个非接触式温度测量来满足测量要求,本文是红外测温仪的设计的实际需要。红外测温仪是利用黑体辐射定律为基础，是光学理论和微电子学综合发展的现象。与基本的测温方式相比，具有反应时段短、非触碰、不干扰被测温场、使用寿命长、操做简便等一系列优点。本文阐述了红外测温仪的基本原理和显示方式，指出红外测温系统的中心控制单元以STC89C51单片机。具体列举了该系统的组成和制作方法，给出了硬件理论图和软件的设计流程图。该系统基本由光学系统、光电探测器、显示输出等部份构成。光学系统的红外辐射能量采集物体的红外能量收集在光电探测器转换成相应的电信号的视野。STC89C51单片机担当节制驱动温度量取、接受量取的数据、并按照单片机中的温度值统计算法算出目的温度值再经过LCD把温度显示出来。关键词: STC89C51单片机；红外测温；LCD显示屏 PAGE \* MERGEFORMAT PAGE \* MERGEFORMAT IIABSTRACTThe use of temperature measurement technique is common, but in the current issue of the detection device class is still a very important technology. It requires the use of measurement and the object contact temperature sensor, This is the actual need infrared thermometer designed.Infrared thermometer is the use of blackbody radiation law, based on the phenomenon of optical theory and integrated development of microelectronics. Compared with the basic temperature measurement mode, with a short response time, non-touch, no interference is temperature field, long life, easy operation to do a series of advantages.This paper describes the basic principles and display infrared thermometer, noting that the center of the infrared temperature measurement system control unit STC89C51 microcontroller. accepted amount,and calculates the temperature in accordance with the purpose of single-chip temperature values through statistical algorithms and then the temperature LCD display.Keywords: STC89C51 microcontroller；infrared temperature measurement； LCD display目 录TOC \o "1-3" \h \u HYPERLINK \l "_Toc444925612" 摘 要 PAGEREF _Toc444925612 \h I HYPERLINK \l "_Toc444925613" ABSTRACT PAGEREF _Toc444925613 \h II HYPERLINK \l "_Toc444925614" 第1章 绪 论 PAGEREF _Toc444925614 \h 1 HYPERLINK \l "_Toc444925615" 1.1课题背景 PAGEREF _Toc444925615 \h 1 HYPERLINK \l "_Toc444925616" 1.2 国内外研究状况 PAGEREF _Toc444925616 \h 2 HYPERLINK \l "_Toc444925617"
