First, a specific structure of the temperature measuring instrument used in the embodiment of the present application is explained: in the related art, a temperature measuring instrument usually adopts an independent sensor to measure the temperature of an object to be detected, namely an object to be detected, and the temperature measuring instrument has certain standing time and stable time, so that the accuracy of the measured temperature is often insufficient. The temperature measuring instrument used in the embodiment of the application is added with a certain number of sensors on the original basis, and specifically comprises three sensors, wherein one sensor is used for acquiring the temperature of the environment where an object to be measured is located and is marked as a first sensor; the other sensor is used for acquiring the temperature of the shell of the measuring instrument and is marked as a second sensor; and the other sensor is used for acquiring the temperature of the object to be measured and is marked as a third sensor.
When the thermometer is not measuring temperature, it will be understood that the 3 sensors described above, i.e. the first sensor, the second sensor and the third sensor, will all have an initial temperature. In the embodiment of the present application, the state of the temperature measuring instrument during calibration is regarded as an initial state, and the temperature measuring data parameter of the temperature measuring instrument can be determined during calibration. For example, the temperature measured by the third sensor and the target temperature of the object can be calculated by the formula
To calculate; in the formula, U is the AD value of a thermopile in a thermodetector, S is a thermometric data parameter, and T isuThe temperature measured by the third sensor, denoted as initial temperature, TsIs the target temperature of the test object. Specifically, in the embodiment of the present application, when determining the parameter S, calibration may be performed in a specified temperature environment. And subsequently, when the temperature data obtained by temperature measurement is subjected to continuous compensation, determining the relationship between the temperature measurement time and the sensor to obtain a group of correction formulas taking the calibrated data as the reference.
In the embodiment of the application, the relationship between the temperature measuring time and the temperature of the sensors is increased along with the increase of the time, but the increase rates of the 3 groups of sensors are different, so that the increase rate of each group of sensors can be determined, and the formula is obtained: in the embodiment of the present application, the rate of temperature increase detected by the first sensor is denoted as a first temperature increase rate, the rate of temperature increase detected by the second sensor is denoted as a second temperature increase rate, and the rate of temperature increase detected by the third sensor is denoted as a third temperature increase rate.
Referring to fig. 1, the method mainly comprises the following steps:
in the embodiment of the application, in the temperature measurement process, when the temperature measuring instrument measures the object to be measured. Because the temperature needs a certain time to reach a stable state in the measuring process, the temperature variation measured by the first sensor can be obtained, and the temperature rise rate detected by the first sensor, namely the first temperature rise rate, can be obtained by dividing the temperature variation measured by the first sensor by the duration time of the temperature variation process; similarly, a second rate of temperature rise and a third rate of temperature rise are obtained, and the maximum value is determined and recorded as Δ VmaxAnd determining the minimum value of the two values, and recording the minimum value as delta Vmin。
in the embodiment of the present application, as mentioned above, the formula can be used
To calculate the target temperature of the thermometer. In the formula, U is the AD value of a thermopile in a thermodetector, S is a thermodetector parameter, and T isuIs the initial temperature, T, measured by the third sensorsIs the target temperature of the test object.
in the embodiment of the present application,depending on the target temperature and the fitting ratio, one can use the formula Δ T ═ K ═ Δ Vmax-ΔVmin) And determining a temperature compensation value, wherein delta T is the temperature compensation value, and K is a fitting proportion. Specifically, the fitting ratio can be obtained by the following steps:
first, N representative thermometers may be selected, where N is an integer, and for example, 10 thermometers may be selected. Specifically, in some embodiments, the selection method of the thermometers is as follows: the temperature difference measured by 3 sensors is obtained according to the calibration of the 3 sensors in each temperature measuring instrument at a certain ambient temperature at normal temperature (22-28 ℃), and the temperature difference range is selected to cover (0-2). Through the selection purpose, the relation between different temperature differences and time can be obtained, and the compatibility of data is strong.
The temperature points of the data to be collected to determine the fit ratio are then set, for example some ambient or target temperature may be set. Through the design of data acquisition, the temperature can be continuously acquired in the process that the measured temperatures of the N thermometers are stable. In some embodiments, for the measurement of the target temperature, when the maximum temperature difference detected by the first sensor, the second sensor and the third sensor is smaller than a preset threshold, the current temperature data is considered to be stable, and the acquisition of the target temperature is stopped. Specifically, the preset threshold may be flexibly set as needed, for example, may be set to 0.5 degrees celsius.
In the embodiment of the application, the temperature detectors can calculate the target temperature when measuring the temperature, and the parameter S of each temperature detector is acquired through calibration data during calibration, so that the parameter S of each temperature detector may be different, but a fixed parameter S exists once a temperature detector is calibrated. And after the target temperature calculated by each group of initial temperatures is obtained. According to the target temperature and the actual temperature corresponding to the target temperature, the real temperature compensation value delta T is obtainedrealSpecifically, the actual temperature compensation value is the actual temperature-target temperature, and then the first temperature rise rate Δ V is obtained according to the increase rate of the three sensors obtained in each temperature measuring instrument with the calibrated temperature as the reference1Second rate of temperature rise Δ V2Third rate of temperature rise Δ V3. From which it can be ascertainedConstant maximum value DeltaVmaxAnd Δ VminThen according to the formula Δ Treal＝K*(ΔVmax-ΔVmin) And obtaining the most appropriate fitting proportion K through least square fitting according to the obtained multiple groups of real temperature compensation values and the corresponding temperature rise rates. Since there may be multiple data participating in the calculation of the K value, although one K value can be obtained according to each known set of data (i.e., a set of true temperature compensation values and corresponding temperature rise rates), in order to obtain the optimal K value in all data, fitting by a least square method is required. Least squares (also known as the least squares method) is a mathematical optimization technique that finds the best functional match of the data by minimizing the sum of the squares of the errors. Unknown data can be easily obtained by the least square method, and the sum of squares of errors between these obtained data and actual data is minimized.
And 140, obtaining a corrected temperature according to the sum of the temperature compensation value and the target temperature.
In the embodiment of the application, the target temperature after final compensation can be determined according to the obtained temperature compensation value and the target temperature, and recorded as the corrected temperature.
In summary, in the embodiment of the present application, the data processing is divided into 2 parts, and the first part is: in the fitting proportion K determining stage, a real temperature compensation value is determined according to the difference between a plurality of groups of target temperatures and actual temperatures, and the temperature difference of 3 sensors in each temperature measuring instrument is known, so that the K value can be obtained according to formula fitting; the second part is a correction phase, and when the temperature difference of 3 sensors in the thermometer is obtained, the value of K is known according to the difference of delta T-K (delta V)max-ΔVmin) The temperature compensation value Δ T can be obtained, and the temperature compensation value is just the empirical difference of the target temperature from the true temperature, i.e. the target temperature obtained at the beginning is based on
Calculated as an error from the actual target temperature, and the empirical value of this error is determined by Δ T ═ K × (Δ V)max-ΔVmin) Obtained. Therefore, at the time of correction, the finally obtained corrected temperature is equal to the target temperature + the temperature compensation value plus Δ T.
It can be understood that in the embodiment of the application, a temperature rise relationship among a plurality of sensors in the temperature measuring instrument is established, and meanwhile, a correction formula of a temperature compensation value is established to correct the target temperature by taking the parameter during calibration as a reference and the temperature rise rate of the plurality of sensors, so that more accurate temperature data can be obtained, and the accuracy and the stability of temperature measurement are improved.
