Temperature predicting method and device thereof

Abstract

The invention discloses a temperature predicting method. The method comprises the steps that the measured temperature of a measured object is sampled at a fixed frequency to acquire the measured temperature of the measured object detected at each sampling point between a current sampling point and past Mth sampling point, and the measured temperature is divided into N sets of measured temperature data; for each set of measured temperature data, the fitting linear slope of the of temperature changing with time is calculated, wherein the curve is composed of the measured temperature data of the set; when the fitting linear slope of N sets of measured temperature data meets a predicting condition, the prediction increment temperature of the measured object at the current sampling point is calculated according to a prediction increment model; and the prediction temperature of the measured object at the current sampling point is calculated according to the measured temperature and prediction increment temperature of the measured object at the current sampling point and the prediction temperature at a previous sampling point. The invention further discloses a temperature predicting device. According to the invention, 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 a device for predicting temperature. Background technique [0002] The electronic thermometer (or clinical thermometer) is in contact with the measured object through the thermally conductive device, so that the temperature of the thermally conductive device slowly changes to the temperature of the measured object, and then the temperature of the thermally conductive device is obtained by the temperature sensor, thereby obtaining the temperature of the measured object. [0003] Current electronic thermometers generally use the relationship between NTC (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 transfer medium or is incomplete Contact, and the temperature of the NTC probe rises slowly, causing the temperature measurement speed of the t...

[0003] 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, and the temperature of the NTC probe rises slowly, resulting in a decrease in the temperature measurement speed of the thermometer
