毕业设计 I 语音耳温枪的设计摘要 2003 年在我国局部地区流行的 SARS 前期症状是高烧 38℃以上(少数长期病患者除外),红外测温仪可为防止 SARS 的扩散和传播提供了快速、非接触测量手段,可广泛、有效地用于人群的体温排查。红外测温为测量人体温度提供了快速、非接触测量手段,可广泛,有效地用于密集人群的体温排查。非接触红外测温针对特定人群,比如儿童或老年人,有很好的效果,随着生活节奏的变快,父母在忙碌中抽车时间帮助孩子测体温是一件很麻烦的事,而且由于儿童不稳定,好动,通过非接触红外测温仪就可以快速准确地测出体温;老年人活动不便,使用传统的测温计很不方便,而且由于老人眼花也不能看清体温计汞柱的位置,通过非接触红外测温仪就可以很快得到体温, 并且通过语音告诉老人,有异常情况也能及时发现。本设计利用红外测温模块对温度进行测量,利用 LE D键盘模块进行温度显示, 这里设计一种采用 AT89C51 和 SD 系列传感器实现红外测温的方法, 控制温度的测量、显示和播报,完成一个温度测量仪器——耳温枪的设计。该耳温枪的特点是用户在使用时可以听到测量的温度值,也可以在数码管上看到温度值,这就使得测量温度的过程便捷而简单,只需要按一下键盘就可以完成操作,而不需要花太多的时间和精力。关键词: AT89C51 单片机,红外测温,语音毕业设计 II The D esign of the V oice Ear Thermometer ABSTRACT Early symptoms of SARS epidemic inour local area in2003 isa high fever over 38°C (except for a small number of chronically ill patients), infrared thermometer in order to prevent the spread of SARS and spread fast, non-contact measuring means can be widely and effectively used for the investigation of the crowd's body temperature. For measuring body temperature, infrared thermometry provides fast, non-contact measurements, can be widely and effectively used for temperature investigation of the dense crowd. Non-contact infrared temperature measurement for specific populations, such as children or the elderly, have a good effect, with the faster pace of life, parents are busy pumping vehicles to help children measured temperature isa very troublesome thing, and because children with unstable, restless, non-contact infrared thermometer can quickly and accurately measure the body temperature; the elderly with limited mobility, using a traditional thermometer is very convenient, and because of the vertigo of the elderly can not see the thermometer mercury position, through the non-contact infrared thermometer can quickly get the body temperature, and told through the voice for the elderly, there are unusual circumstances also be found in time. This design uses infrared temperature measurement module to measure temperature, temperature display LED keypad m
