Method and device for predicting temperature

Abstract

The invention discloses a method for predicting temperature, comprising: sampling the measured temperature of a measured object at a fixed frequency, and obtaining the measured temperature detected at each sampling point between the current sampling point and the past Mth sampling point The measured temperature of the object, and divided into N groups of measured temperature data; for each group of measured temperature data, calculate the fitting line slope of the temperature versus time curve composed of the group of measured temperature data; when the N groups of measured temperature data When the slope of the fitted line meets the prediction condition, calculate the predicted incremental temperature of the measured object at the current sampling point according to the predicted incremental model; according to the measured temperature and predicted incremental temperature of the measured object at the current sampling point, As well as the predicted temperature at the last sampling point, calculate the predicted temperature of the measured object at the current sampling point. Correspondingly, the invention also discloses a device for predicting temperature. By adopting the embodiment of the invention, the temperature measurement can be accelerated, and the anti-interference ability is strong.

Description

technical field [0001] The invention relates to the field of temperature detection, in particular to a method and device for predicting temperature. Background technique [0002] The electronic thermometer (or thermometer) contacts the measured object through the heat conduction device, so that the temperature of the heat conduction device slowly changes to the temperature of the measured object, and then obtains the temperature of the heat conduction device through the temperature sensor, thus obtaining the temperature of the measured object. [0003] The current electronic thermometers generally use the relationship between NTC (Negative Temperature Coefficient, negative temperature coefficient) thermistor and temperature to measure the temperature of the measured object, but the contact between the NTC probe and the measured object has a transmission medium or cannot be completely contact, the temperature of the NTC probe rises slowly, resulting in a decrease in the tempe...
