基于单片机实现红外测温仪设计

基于单片机实现红外测温仪设计摘要：温度被广泛使用。温度测量方法大致可分为有形和无形两种。触摸测温的优点是简单、可靠、准确度高，但当达到温度时，温度传感器和测量接触设备必须分开测量温度，所以缺点是反应时间较长。另外，在很多应用中，温度传感器不能与被测对象连接，这就需要一种测量不稳定温度的方法来满足要求。红外测温是用红外表在物体上测量物体的温度。具有高温分离率高、反应速度快、温度范围广、稳定性好等特点。本说明书是为满足上述实际要求而设计的红外测温仪。本文介绍了红外测温仪测温的基本原理和理解，提出了以STC89C51红外测温仪系统为主要控制元件。详细了解系统的功能和设计，并提供软件和硬件流程的系统图。该系统主要由红外温度传感器、时钟块、单片机、液晶显示器、电源控制等部分组成。红外温度传感器在视野范围内捕获红外仪表的能量，并将红外能量集中在光倍增器上，并将其转换为电子相似的信号。STC89C51单片机负责控制和启动断路器的时钟信号，测量温度，测量数据并根据温度算法在一处计算温度值和目标日期和时间，复制到微型计算机并在LCD上显示结果。关键词：单片机：红外测温：设计Design of infrared thermometer based onsingle chip microcomputerAbstract Temperature is widely used.Temperature measurement methods can beroughly divided into tangible and intangible.The advantages of touch temperaturemeasurement are simplicity,reliability and high accuracy,but when the temperature is reached,the temperature sensor and measuring contact equipment must measure the temperatureseparately,so the disadvantage is that the reaction time is long.In addition,in manyapplications,the temperature sensor can not be connected with the measured object,whichrequires a method to measure the unstable temperature to meet the requirements.Infraredtemperature measurement is to measure the temperature of an object with a red surface.It hasthe characteristics of high separation rate at high temperature,fast reaction speed,widetemperature range and good stability.This manual is an infrared thermometer designed tomeet the above practical requirements.This paper introduces the basic principle and understanding of infrared thermometer,andputs forward that STC89C51 infrared thermometer system is the main control element.Understand the function and design of the system in detail,and provide the system diagram ofsoftware and hardware flow.The system is mainly composed of infrared temperature sensor,clock block,single chip microcomputer,liquid crystal display,power control and so on.Theinfrared temperature sensor captures the energy of the infrared instrument in the visual field,concentrates the infrared energy on the photomultiplier,and converts it into an electronicallysimilar signal.The STC89C51 single chip microcomputer is responsible for controlling andstarting the clock signal of the circuit breaker,measuring the temperature and data,calculatingthe temperature value and the target date and time in one place according to the temperaturealgorithm,copying it to the microcomputer and displaying the results on the LCDKeywords:single chip microcomputer;Infrared temperature measurement;design目录第1章引言1.1研究背景…1.2研究意义1.3研究内容1.4国内外研究现状.2第2章方案分析与选择..32.1设计方案……32.2方案论证3第3章系统的硬件设计3.1单片机模块43.2红外测温模块3.3DS1302时钟模块..103.4电源模块.123.5CD显示模块.12第4章系统的软件设计154.1软件的设计架构…154.2主控程序154.3应用模块16第5章系统仿真.195.1keil介绍.195.2 protues介绍245.3DXP介绍,25第6章系统调试,276.1电路的组装276.2硬件调试276.3软件调试276.4软硬件联合调试28第7章结论…29致谢.30参考文献31
