非接触式的红外测温系统 桂林电子科技大学毕业设计(论文)报告用纸 - I - 摘 要 红外模组是汇集其视场内目标的红外辐射能量，将红外能量聚焦在光电探测仪上并转变为相应的数字信号的传感器，它具有非接触测温方式、温度分辨率高、响应速度快、不扰动被测目标温度分布场、测量精度高、稳定性好和使用寿命长等一系列优点，比传统的接触式测温有更多的场合适应性。 本文介绍了一种基于单片机实用温度实时检测和记录系统。它的设计思路主要是利用红外模组传感器，采集人体发射出的红外线，得到数字信号送入单片机，由MCS-51单片机通过温度补偿来实现温度值的转换并送入LCD1602显示和超温声光报警功能，同时通过无线模块进行中短距离传输到PC机和组态王Kingview进行数据的保存和后台处理等功能。本设计实现了非接触式的温度测量，并且感应时间在3秒以内，分辨力达到0.01?C,精度在0.5?C以内，实现了无线传输到组态王的控制，并且在组态王上实现了温度的存储、查询、报表显示等多种功能。 关键词:红外测温系统;非接触式;组态王;无线传输 桂林电子科技大学毕业设计(论文)报告用纸 - II - Abstract The Infrared module is to bring together its field of view infrared radiation energy goals will focus infrared energy on a photoelectric detector and digital signal into a corresponding sensor, which has non-contact temperature measurement method, temperature, high resolution, fast response, without disturbing the measured target temperature distrbution field, high accu- racy, good stability and long life and a series of advantages over traditional contact-type temperature adaptability more occasions. This paper introduces a practical temperature based on single chip real-time detection and recording system. Its design concept is the use of the main infrared sensor module to collect the body emits infra-red, get the digital signal into the microcontroller, the MCS-51 microcontroller to achieve temperature compensation by the conversion temperature and over-temperature into the LCD1602 display and sound and light alarm , Through short-range wireless module for transmission to the PC, and Kingview preservation and back-office data processing functions. The Design and Implementation of a non-contact temperature measurement, and induction time of 3 seconds or less, resolution to 0.01 ? C, accuracy 0.5 ? C or less, to achieve the wireless transmission to the configuration control of the king and the king on the configuration Achieved temperature storage, query, report shows and other features. :Infrared temperature measurement system;non- contact;Kingview;wireless- Key Words
