Specific embodiment
With reference to Fig. 1, body temperature measurement method in an embodiment can be applied to clinical thermometer, include the following steps.
S110：The observed temperature at each moment is increased according to preset temperature control, and the observed temperature for acquiring each moment is drawn
Survey Temperature changing curve.
Observed temperature is increased by control and obtains observed temperature change curve, and the heat between human body and clinical thermometer can be improved
Exchange velocity.The observed temperature that each moment is increased according to preset temperature control, refers to the reality for obtaining each moment by additional means
Testing temperature increases, to accelerate the rising of measurement initial stage temperature.Additional means include but is not limited to control to generate heat by processor
The temperature sensor of resistance heating body temperature meter, so that the temperature that temperature sensor measures increases.
Wherein, preset temperature refers to the pre-set value for needing to control observed temperature and reaching, and can have according to actual needs
Body setting.For example, can be set preset temperature for 35 DEG C (degree Celsius), then can control each moment observed temperature increase until
Observed temperature stops control after reaching 35 DEG C.It is appreciated that in other embodiments, preset temperature may be other numerical value.
S130：According to the observed temperature variable quantity in actual measurement Temperature changing curve detection preset duration, become in observed temperature
When change amount is greater than or equal to preset threshold, to correspond to last moment of preset duration as initial time, according to preset interval to reality
It surveys Temperature changing curve and carries out piecewise fitting straight line, obtain straightway.
Observed temperature variable quantity refers to that observed temperature corresponding to preset duration corresponding finish time and initial time institute are right
The temperature difference between observed temperature answered.Observed temperature variable quantity be greater than or equal to preset threshold, indicate temperature changing speed compared with
Fastly.The last moment of corresponding preset duration refers to when detecting that observed temperature variable quantity is greater than or equal to preset threshold, when this is default
Last moment in period where long, for example, detecting in the 4th second to the 8th second this period the actual measurement of (preset duration is 4 seconds)
Temperature variation is greater than preset threshold, then with the 8th second for initial time.Wherein, preset duration, preset threshold, preset interval can
With specific setting according to actual needs.In the present embodiment, preset duration is 4 seconds；Preset threshold is 2 DEG C；Preset interval is 10 seconds.

The slope differences of latter straightway obtain ratio.
Step (a2)：Whether detection ratio is less than or equal to the second preset value, when ratio is less than or equal to the second preset value
When determine that the observed temperature of the last moment of corresponding straightway reaches stable.
Wherein, the second preset value is related with clinical thermometer hardware and sensor parameters, can determine in real data.Second
Preset value is less than the first preset value.Ratio is less than or equal to the second preset value, indicates the actual measurement of the last moment of corresponding straightway
