摘　　要：为了设计低成本、易操作的温度监测网,采用多片单线温度(DS18B20)组成阵列,实现了对多点温度数据的采集.并介绍美国DALLAS公司单线数字温度传感器DS18B20的特性,给出在VC环境下PC机通过并口对各个温度传感器进行信息交换,完成温度监控操作的过程.For designing cheap and convenient temperature monitoring network,temperature data acquisition system was completed by using multi-DS18B20 in this paper. The characteristics of the 1-wire temperature sensor DS18B20 were introduced. Every sensor was controlled to exchange information with PC and fulfilled temperature monitoring in VC environment through the PC's parallel port.
