1、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
2、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AbstractTheInfraredmoduleistobringtogetheritsfieldofviewinfraredradiationenergygoalswillfocusinfraredenergyonaphotoelectricdetectoranddigitalsignalintoacorresp
