摘要
本文介绍了以高精度高集成性的放大器ＴＬＶ２３２２、高精度的多路模数转换器ＴＬＣ２５４３为核心，以８０３１为ＣＰＵ的数字式贝克曼温度计功能样机的硬件和软件设计方案，该样机比起玻璃式贝克曼温度计有诸多优点，克服了玻璃式贝克曼温度计操作复杂、读数误差大的主要缺点。
This paper introduces a hardware and software design of digital thermometer, which is centered by high precise integrated amplifier TLV2322 and high precise multiple converter TLC2543. It is controlled by microcomputer 8031, this thermometer is superior than glass Beckman thermometer because of its convenient operation and precise reading.
