摘　　要：阐述单总线数字温度传感器DS18B20的基本工作原理和使用方法;设计基于AVR单片机与多个DS18B20温度传感器连接的一线总线采集系统,并分析由多个DS18B20组成的温度传感器网络的自动搜索算法.系统利用单片机AT90S8515控制数字温度计,采用温度传感器DS18B20进行温度采集,系统测量分辨率最小可达0.062 5℃.这种数字式温度计比传统的温度计测量准确、便于读数、抗干扰性强.This paper introduces 1-wire digital temperature sensor DS18B20 and its application in temperature control system. Our system uses SCM AT90S8515 to control temperature and temperature sensot DS18B20 to collect temperature, which makes the range of measurement from - 55 ℃ to 125 ℃, the minimum resolution up to 0.062 5 12 and accuracy reach ±0.5 12. We explain the basic working principles and methods of single-bus digital temperature sensor DS18B20, and design collection system based on AVP SCM connected with a number of DS18B20 temperature sensors, and analysis automatic searching algorithm of temperature sensor network consists of multi- DS18B20 as well. Compared with traditional thermometers, digital thermometers are more precise and anti-jamming, and easy to read. The wide use of this digital thermometer is easily to seen in the future.
