【Abstract】 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.更多还原
