But in some application domains, we needn’t the sensor contact with the measured object which used in temperature measurement, this needs a kind of noncontact temperature measurement to satisfies the demand and the design of this infrared thermometer is also based on the demand. Infrared thermomter, it uses the blackbody radiation laws as the theories foundation, it is the oute that the optical theories and microelectronics learn a prehensive development. Compared to the way of traditional temperature measurement, it has a series of merits, such as short in response ti me, noncontact, noninterference to temperature field, long useful time and convenient operation, etc. The paper introduces the basic principle of infrared thermometer and the method of realization, puts forward infrared trermometer system with the STC89C51 MCU as the CPU. The paper introduces the posing and the method of that system in detail, and gives the hardware principle diagram and the design flow chart of the software. The system formed by the optical system, photoelectron detector,display and output partially. The optical system collects the infrared radiation energy of the object in its field of view, the infrared energy focusing on the instrument and transforms to the corresponding electrical signal. The STC89C51 MCU is used to start the temperature survey, data receive, count the value of the object temperature based on the arithmetic with in MC U and the result is displayed on LED. iii KEYWORDS: The STC89C51 MCU, infrared radiation thermometry, the LED display iv 目 錄 前 言 ............................................................... 1 第一章 紅外測(cè)溫系統(tǒng)的 設(shè)計(jì) 背景及方案介 紹 ..................... 2 167。光學(xué)系統(tǒng)匯集其視場(chǎng)內(nèi)目標(biāo)的紅外輻射能量，紅外能量聚焦在光電探測(cè)儀上并轉(zhuǎn)變?yōu)橄鄳?yīng)的電信號(hào)。詳細(xì)介紹了該系統(tǒng)的構(gòu)成和實(shí)現(xiàn)方式，給出了硬件原理圖和軟件的設(shè)計(jì)流程圖。與傳統(tǒng)的測(cè)溫方式相比，具有響應(yīng)時(shí)間短、非接觸、不干擾被測(cè)溫場(chǎng)、使用壽命長(zhǎng)、操作方便等一系列優(yōu)點(diǎn)。本論文正是應(yīng)上述實(shí)際需求而設(shè)計(jì)的紅外測(cè)溫儀。 i 非接觸式紅外測(cè)溫儀設(shè)計(jì) 摘 要 溫度測(cè)量技術(shù)應(yīng)用十分廣泛，而且在現(xiàn)代設(shè)備故障檢測(cè)領(lǐng)域中也是一項(xiàng)非常重要的技術(shù)。但在某些應(yīng)用領(lǐng)域中，要求測(cè)量溫度用的傳感器不能與被測(cè)物體相接觸，這就需要一種非接觸的測(cè)溫方式來(lái)滿足上述測(cè)溫需求。 紅外測(cè)溫儀是以黑體輻射定律作為理論基礎(chǔ)，是光學(xué)理論和微電子學(xué)綜合發(fā)展的產(chǎn)物。 本文介紹了紅外測(cè)溫儀測(cè)溫的基本原理和實(shí)現(xiàn)方法，提出了以 STC89C51單片機(jī) 為其核心控制部件的紅外測(cè)溫系統(tǒng)。該系統(tǒng)主要由 光學(xué)系統(tǒng)、光電探測(cè)器、顯示輸出等部分組成。 STC89C51 單片機(jī)負(fù)責(zé)控制啟動(dòng)溫度測(cè)量、接收測(cè)量數(shù)據(jù)、 并 按照 單片機(jī)中的溫度值計(jì)算 算法計(jì)算出目標(biāo)的溫度值 再通過(guò) LED 把結(jié)果顯示出來(lái) 。 溫度測(cè)量技術(shù)的概述 .............................. 2 167。 紅外測(cè)溫系統(tǒng)的方案介紹 ......................... 5 第二章 紅外測(cè)溫系統(tǒng)的硬件設(shè)計(jì) ................................. 7 167。 紅外測(cè)溫模塊 ................................... 10 167。 電源模塊 ...................................... 13 167。 LED 顯示模塊 ................................... 14 第三章 紅外測(cè)溫系統(tǒng)的軟件設(shè)計(jì) .......................... 17 167。 紅外測(cè)溫程序模塊 .............................. 18 167。 顯示程序模塊 .................................. 22 總結(jié) .................................................... 23 參考資料 ................................................ 24 致 謝 ................................................... 24 附 錄 ................................................... 24 英文翻譯 ................................. 錯(cuò)誤 !未定義書(shū)簽。在工業(yè)生產(chǎn)中，我們通常通過(guò)測(cè)量設(shè)備表面的溫度來(lái)監(jiān) 測(cè)設(shè)備的運(yùn)行狀況，而現(xiàn)代的工業(yè)設(shè)備往往是在高電壓、大電流等危險(xiǎn)情況下運(yùn)行的，傳統(tǒng)依靠人工接觸式檢測(cè)的方法既浪費(fèi)時(shí)間、人力，又帶有一定的危險(xiǎn)性，同時(shí)對(duì)測(cè)溫儀所采用的材質(zhì)也有嚴(yán)格的限制。 針對(duì)現(xiàn)
