摘　　要：提出了一种利用传统K型热电偶,通过多功能1-WIRE芯片DS2760在冷端直接进行数字转换的方法,实现对温度更宽范围的、更低成本的测量方案。同时,利用这种测量方法和1-WIRE网络及其器件的特性,提出了一种基于ICP/IP协议的网络化温度测量、控制系统设计方案。This paper put forward a method that adopt the traditional K type thermocouple by using the multifunctional 1 -WIRE chip DS2760 directly carried out the digital transition at the gelid end. We can achieve to measure temperature more widely and lower cost. Meanwhile, by exploiting this measuring method and the characteristic of 1-WIRE net and its parts, a design scheme are put forward which it based on ICP/IP protocol and can realize network temperature measurement and control system.
