The present invention relates to the technical field of industrial temperature measurement, in particular to a method for rapid temperature measurement using an ordinary temperature sensor, comprising the following steps: S1, establishing a temperature-time response model, obtaining a relationship curve between temperature sensor output temperature and time, using a polynomial Fit the relationship curve to obtain a coefficient matrix composed of polynomial coefficients; S2, put the temperature sensor into the measured environment, measure the actual temperature of the temperature sensor at multiple times, and the multiple times are far less than the thermal equilibrium time; S3, according to The coefficient matrix, the polynomial, the time in step S2, and the measured temperature are calculated to obtain the final temperature. The present invention only measures the actual measured temperature at multiple moments that are much shorter than the thermal equilibrium time during formal temperature measurement, and then calculates the temperature to be measured by combining the coefficient matrix and polynomial, and the time required for the entire measurement and calculation process is much shorter than the thermal equilibrium time. The rapid temperature measurement using common temperature sensor is realized.
Description
technical field [0001] The invention belongs to the technical field of industrial temperature measurement, and in particular relates to a method for rapidly measuring temperature by using an ordinary temperature sensor. Background technique [0002] In industrial applications, a large number of temperature sensors are used to measure the real-time temperature in the manufacturing process, and temperature data is used to monitor the execution of the manufacturing process or as an important basis for modifying process parameters. In the process of temperature measurement, the heat balance process of the temperature sensor always takes a certain amount of time. Here we refer to the time it takes for the sensor to start working to the heat balance state as the heat balance time. Strictly speaking, the temperature obtained after the temperature measurement must wait longer than the thermal equilibrium time is the accurate temperature of the tested part. Therefore, in the actual ...
