基于 51 单片机温度测量控制系统设计摘 要伴随科技不停进步，在工业生产中温度是常见被控参数，而实行单片机来对这些被控参数进行控制已成为当今主流。温度传感器 DS18B20 含有性能稳定、灵敏度高、抗干扰能力强、使用方便等优点，广泛应用于冰箱、空调器、粮仓等日常生活中温度测量和控制。本文实行 51 单片机来实现对温度测量和控制。它关键组成部分有：AT89S52 单片机最小系统，DS18B20 测温电路,按键电路、LCD1602 显示电路，蜂鸣器报警电路。它能够实时地检测和显示温度，能够设定温度范围，实现对温度报警和自动控制。关键词：温度；51 单片机；DS18B20；测量和控制。 ABSTRACTTemperature sensor DS18B20 has a lot of advantages,such as stable performance,high sensitivity,strong anti-interference capability,convenience of use,etc. And it was widely used for the measurement and control of temperature in refrigerators, air conditioners, barn and other daily life in the measurement and control of temperature. In this article ,We used a single chip for realizing temperature measurement and alarm. It was mainly component of AT89S52 chip, DS18B20, keyboard and display circuit , temperature alarm and control circuit. It realize not only real-time detection and display temperature, but also setting the temperature range and the measurement and control of temperature.Key words: Temperature; 51 MCU; DS18B20; Measurement and control目录1 引言..................................................................................................................................................................11.1 温度测量控制系统设计背景、进展历史及意义.................................................................................11.2 温度测量控制系统目标........................................................................................................................11.3 温度测量控制系统完成功效............................................................................................................
