Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
As shown in Figure 1, a kind of flow chart of the embodiment of the detection method of thermometer of the invention, comprising:
S11, in the detection instruction for recording test ambient temperature value T0 for receiving user's input, start recording temperature
The collected each measured temperature of temperature sensor in meter；
S12 obtains the final stationary value T1 of the measured temperature；
S13 judges whether the thermometer is qualified according to the test ambient temperature value T0 and the final stationary value T1；
S14 passes through the indicate indicator being arranged on the thermometer according to judging result and indicates to the user that the thermometer
Acceptance or rejection.
In embodiments of the present invention, in the inspection for recording the test ambient temperature value T0 for receiving user's input
After surveying instruction, each of collected described thermometer of start recording temperature sensor measured temperature simultaneously finally obtains institute
State the final stationary value T1 of measured temperature.Testing ambient temperature value T0 is a steady state value, i.e. survey locating for dut temperature meter
Test ring border is an isoperibol.For example, test environment is one 37 DEG C of insulating box.When dut temperature meter is placed on the survey
When under test ring border, the temperature test value of record is gradually close to T0, and eventually stable in a numerical value.This is finally stable
Numerical value is above-mentioned final stationary value T1.The embodiment of the present invention is according to the test ambient temperature value T0 and the final stabilization
Value T1 judges whether the thermometer qualified, and by judging result pass through the indicate indicator that is arranged on the thermometer to
User indicates the thermometer acceptance or rejection.Since the entire detection process of the thermometer is by procedure auto-control, no
There are artificial interference, therefore reduce the time of the thermometer detection, improve the efficiency of the thermometer detection；Together
When, whether the thermometer is qualified to indicate to the user that judging result by procedure judges and by the indicate indicator, does not deposit
It is artificially reading, is avoiding artificial erroneous judgement, improving the accuracy of the thermometer detection.
Preferably, the detection method of the thermometer further include receive user input record test environment temperature
When the detection instruction of value T0, the step of start recording length of testing speech；
As shown in Fig. 2, step S12 is specifically included in the first embodiment of step S12:
S121, judges whether the length of testing speech reaches preset first duration threshold value；
S122 collected measured temperature will make at this time when the length of testing speech reaches the first duration threshold value
For the final stationary value T1 of the measured temperature.
Since under the test environment of constant temperature, measured temperature can be settled out finally, therefore pass through the first duration of setting
Threshold value determines that measured temperature no longer changes when by the first duration threshold value, and by collected temperature at this time

And calculated according to T2 and T1 corresponding time point be changed to T1 from T2 required for change duration；Wherein, D2 is preset
Second temperature difference threshold value；
S137, when the variation duration is less than preset second duration threshold value or is greater than preset third duration threshold value,
Determine that the thermometer is unqualified；
S138, when the variation duration is greater than or equal to the second duration threshold value and is less than or equal to the third
When long threshold value, determine that the thermometer is qualified.
Based on convenient principle, in the production process of existing thermometer, although thermometer is possible to be placed on thermometer inspection
Long time inside device is surveyed, but we only do the limitation of shortest time to the temperature test time of thermometer, and not
Temperature rise (or temperature drop) time of thermometer is judged.Therefore, in the case where thermometer temperature rise (or temperature drop) is excessively slow, even if
The accuracy test of thermometer is qualified, and also there is also 2 hidden danger.First, the accuracy test qualification of thermometer be it is false, due to temperature
The temperature rise (or temperature drop) for spending meter is excessively slow, if the re-test longer time, the temperature of thermometer is possible to be more than locating constant temperature ring
The actual temperature in border；Second, there is no problem for the precision of thermometer itself, but since the temperature rise of thermometer (or temperature drop) is excessively slow,
This is also another mass defect of product, and when user uses, the precision that user is easy to sensible temperature meter, which exists, is asked
Topic.

The judgement for rising (or temperature drop) time, using test error and temperature rise (or temperature drop) time as judge thermometer whether He Ge finger
Mark, the too fast or too slow thermometer of temperature rise is all determined as it is unqualified, so as to more accurately judge that tested thermometer is
No qualification.
Since variation duration once finally can farthest reflect the temperature change speed situation of thermometer,
Preferably, the second temperature difference threshold value D2 in the present embodiment is 1 DEG C.
