Abstract: In the process of calefying water, the speed of calefying water varies when the quantity is different. Taking the speed of califying water as a detecting signal, in the process of calefying water, a maths model of calefying water is established to differentiate the quantity of water for the purpose of replacing sensor through using subsection optimal slope mean to measure water boiling point. In accordance with the characteristic of the varying rate of temperature declining in the course of water boiling, a calculating formula of small quantity of water and a comparing table of large quantity of water linear relevant parameters are established by analyzing experiment data. The experiments prove that under the condition of the given low configure hardware, the optimal measuring result can be acquired by applying soft-sensor technology.
