A smoothing step: and smoothing the temperature value TP to obtain a temperature value T.
In order to ensure that the temperatures measured by the first temperature sensor and the second temperature sensor are the same, the measurement error needs to be calibrated first, so that the temperature measurement errors between the first temperature sensor and the second temperature sensor are reduced within a certain temperature measurement range, and the implementation method comprises the following steps:

2. A relatively constant ambient temperature value measured using a standard thermometer is denoted as TTP.
3. Under this condition, the temperature value TT1 measured by the first temperature sensor and the temperature value TT2 measured by the second temperature sensor are recorded.
4. And subtracting the standard temperature from the measured temperature, and calculating to obtain a calibration factor of the corresponding temperature sensor. That is, the first temperature sensor calibration factor is recorded as a first calibration factor D1, where D1 ═ TT 1-TTP. The second temperature sensor calibration factor is recorded as a second calibration factor D2, where D2 ═ TT 2-TTP.
5. In the first calibration step, temperature value T11 ═ temperature value T1 — first calibration factor D1. In the second calibration step, temperature value T21 is temperature value T2 — second calibration factor D2.
