体表测温的补偿关系研究
首发时间:2011-10-27
摘要:本研究项目是设计一种电子体温计,通过大量的查阅资料,初步确定两种测温方式:体表测量和红外测量,其中本研究重点分析体表测温,并且采用接触式传感器DS18B20采集数据,通过AT89S52为芯片的单片机将数据记录。本研究项目将通过大量数据测量绘制每一组数据的变化趋势,找到每个曲线的拐点,然后归纳出体表温度和实际体温的动态温差补偿函数或补偿表,在实际测量时,通过实测温度加补偿温度给出实际体温,体温可通过显示和语音播报的形式给出。本文将重点介绍测量体温的方案选择和利弊分析。

Surface temperature compensation relations
Abstract:This research project is to design an electronic thermometer, through a lot of access to information, initially to confirm the temperature measurement methods: surface measurements and infrared measurements, which this study focused on analyzing the surface temperature, and the use of contact sensor DS18B20 data collection, AT89S52 microcontroller chip through the data for the record. This research project will draw large amounts of data measuring trends in each set of data to find the inflection point of each curve, and then summarize the actual temperature of the surface temperature and dynamic temperature compensation function or compensation table, the actual measurement, by measuring the temperature given the actual temperature plus the temperature compensation, temperature display and voice broadcast through the form given. This article will focus on measuring the temperature of the program options and the pros and cons analysis.
