A kind of detection system based on DS18B20 digital blast furnace cooling water temperature difference is introduced.In this system of blast furnace

DS18B20 collects each measuring point of the cooling water temperature and transmits digital temperature information to the monitoring PC through the CAN bus network

providing important reference data for the protection of blast furnace production safety.Aiming at the feature of blast furnace cooling water temperature difference measurement points

high precision

combined with the characteristics of DS18B20 and the analysis of principle of the internal structure

the DS18B20 multipoint temperature measuring method is mainly discussed

and least square method is used to process measured data of system

and to achieve high precision detection purposes.The hardware of the whole system is simple

convenient networking

high temperature measuring precision

accurate data transmission

and can be applied in multiple temperature measurement occasions in daily life

industrial and agricultural production.
