摘　　要：介绍了单线数字温度传感器DS18820的特性及工作原理,并给出了在VC环境下多片DS18820与计算机并口相连组成温度监测网的实现方法。DS18820的单总线等特点使其构成的测温网络设计灵活,方便,传输距离远且抗干扰,易于扩充维护,适合于在恶劣环境下进行现场温度测量,结果表明,此设计基本上达到了预期的目标。The characters and operational principles of I-wire digital temperature sensor DS18B20 were introduced, and a temperature measurement network under VC environment making use of DS18B20 and PC＇s parallel port was also described. The network which was composed of I-wire DS18B20 possessed some advantages such as resisting interference, convenient and easily being maintained. The results showed that the anticipated aim was basically achieved.
