摘要
分析了１位总线数字温度传感器ＤＳ１８２０运行特点，提出对以ＤＳ１８２０组成的多测点温度采集系统的并行采样的处理方法。
The operation features of an 1-wire digital thermometer DS1820 are described. A multi-point thermometry system which consists of multiple DS1820 by using parallel control method is proposed. The method can raise the system's data acquisition speed.
