The embodiment of the application provides a correction method of temperature data based on a thermometer, and the fusion method of the embodiment of the application can be applied to a terminal, a server, software running in the terminal or the server and the like. The terminal may be, but is not limited to, a tablet computer, a notebook computer, a desktop computer, etc. The server may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDNs, basic cloud computing services such as big data and artificial intelligent platforms.
First, a specific structure of the thermo detector used in the embodiment of the present application will be described: in the related art, a single sensor is often adopted to measure the temperature of an object to be detected, namely an object to be detected, and the temperature measuring instrument has a certain standing time and a certain stabilizing time, so that the measured temperature is often not accurate enough. The temperature measuring instrument used in the embodiment of the application is added with a certain number of sensors on the original basis, and concretely comprises three sensors, wherein one sensor is used for acquiring the temperature of the environment where the object to be measured is positioned and is recorded as a first sensor; the other sensor is used for acquiring the temperature of the shell of the measuring instrument and is recorded as a second sensor; and one sensor is used for acquiring the temperature of the object to be detected and is recorded as a third sensor.
When the thermometer is not measuring temperature, it will be appreciated that the 3 sensors described above, namely the first sensor, the second sensor and the third sensor, will all have an initial temperature. In the embodiment of the application, the state of the thermometer in calibration is regarded as an initial state, and the temperature measurement data parameters of the thermometer can be determined in calibration. For example, for the temperature measured by the third sensor and the target temperature of the object to be measured, the temperature can be calculated by the formulaCalculating; wherein U is AD value of a thermopile in the thermometer, S is a temperature measurement data parameter, T u is temperature measured by the third sensor, recorded as initial temperature, and T s is target temperature of an object to be measured. Specifically, in the embodiment of the application, when the parameter S is determined, the determination can be calibrated in a specified temperature environment. And when the temperature data obtained by temperature measurement is subjected to continuous compensation, determining the relation between the temperature measurement time and the sensor, and obtaining a group of correction formulas taking the calibrated data as a reference.
In the embodiment of the application, the relation between the temperature measurement time and the sensor temperature increases along with the increase of time, but the increase rates of 3 groups of sensors are different, so that the increase rate of each group of sensors can be determined, and the formula is obtained: Δt=k×Δv, where Δt is a temperature compensation amount, K is a fitting ratio, Δv is a temperature rise rate measured by the sensor, and in the embodiment of the present application, a rate of temperature rise detected by the first sensor is denoted as a first temperature rise rate, a rate of temperature rise detected by the second sensor is denoted as a second temperature rise rate, and a rate of temperature rise detected by the third sensor is denoted as a third temperature rise rate.
Referring to fig. 1, the method mainly includes the steps of:
Step 110, when the thermometer measures the object to be measured, acquiring a first temperature rise rate of the first sensor, a second temperature rise rate of the second sensor, a third temperature rise rate of the third sensor and an initial temperature detected by the third sensor;
In the embodiment of the application, in the temperature measuring process, when the temperature measuring instrument measures the object to be measured. The temperature can reach a stable state only after a certain time is needed in the measurement process, so that the temperature change quantity measured by the first sensor can be obtained and divided by the duration time of the temperature change process to obtain the temperature rise rate detected by the first sensor, namely the first temperature rise rate; similarly, the second and third rates of temperature rise are obtained, the maximum of which is determined, denoted as DeltaV max, and the minimum of which is determined, denoted as DeltaV min.
Step 120, determining a target temperature of the thermometer according to the initial temperature;
In the embodiment of the present application, as described above, the formula may be To calculate the target temperature of the thermometer. Wherein U is the AD value of the thermopile in the thermometer, S is the parameter of the thermometer, T u is the initial temperature measured by the third sensor, and T s is the target temperature of the object to be measured.
Step 130, determining a temperature compensation value according to the target temperature and the fitting proportion through a formula Δt=k (Δv max-ΔVmin); wherein, deltaT is a temperature compensation value, K is a fitting proportion, deltaV max is the maximum value of the first temperature rise rate, the second temperature rise rate and the third temperature rise rate, deltaV min is the minimum value of the first temperature rise rate, the second temperature rise rate and the third temperature rise rate;
In the embodiment of the present application, according to the target temperature and the fitting ratio, the temperature compensation value may be determined by the formula Δt=k (Δv max-ΔVmin), where Δt is the temperature compensation value and K is the fitting ratio. Specifically, the fitting ratio can be obtained by:
First, N representative thermometers may be selected, where N is an integer, for example, 10 thermometers may be selected. Specifically, in some embodiments, the selection method of the thermo detector is as follows: according to the temperature difference measured by 3 sensors obtained when the 3 sensors in each thermometer are calibrated at a certain ambient temperature (22-28 ℃), the temperature difference range is selected to cover (0-2). By the selection purpose, different relations between temperature differences and time are obtained, and data compatibility is strong.
The data temperature points to be acquired for determining the fitting ratio are then set, for example, some ambient temperature or target temperature may be set. Through the design of data acquisition, the temperature measuring device can continuously acquire in the process that the measured temperature of N thermometers reaches stability. 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 the 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 required, for example, may be set to 0.5 degrees celsius.
In the embodiment of the application, when the temperature of the thermometer is measured, the target temperature of the thermometer can be calculated, and as the parameter S of each thermometer is obtained through calibration data in calibration, the parameter S of each thermometer is possibly different, but the fixed parameter S exists once the thermometer is calibrated. After the target temperature calculated for each set of initial temperatures is obtained. According to the target temperature and the actual temperature corresponding to the target temperature, a real temperature compensation value delta T real is obtained, specifically, the real temperature compensation value = the actual temperature-the target temperature, and then according to the growth rate of three sensors obtained from each thermometer by taking the calibrated temperature as a reference, namely a first temperature rise rate delta V 1, a second temperature rise rate delta V 2 and a third temperature rise rate delta V 3. From which the maximum values Δv max and Δv min can be determined, and then the most suitable fitting ratio K can be obtained by least square fitting according to the formula Δt real＝K*(ΔVmax-ΔVmin), the obtained sets of real temperature compensation values and their corresponding temperature rise rates. Since there may be multiple pieces of data involved in the calculation of the K value, although one K value may be obtained from each known set of data (i.e., a set of real temperature compensation values and their corresponding temperature rise rates), in order to obtain the optimal K value in all the data, a least squares fit is required. The least squares method (also known as least squares) is a mathematical optimization technique that finds the best functional match of the data by minimizing the sum of squares of the errors. The unknown data can be easily obtained by the least square method, and the sum of squares of errors between the obtained data and the 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 final compensated target temperature can be determined according to the obtained temperature compensation value and the target temperature and is recorded as the corrected temperature.
In general, in the embodiment of the present application, the data processing is divided into 2 parts, and the first part is: in the step of determining the fitting proportion K, the process determines a real temperature compensation value according to the differences between a plurality of groups of target temperatures and the real temperatures, and the temperature difference of 3 sensors in each thermometer is known, so that the K value can be obtained through fitting according to a formula; the second part is a correction stage, the K value is already known, when the temperature difference of 3 sensors in the thermometer is obtained, according to the delta T=K (delta V max-ΔVmin), the temperature compensation value delta T can be obtained, and the temperature compensation value is exactly the empirical difference of the target temperature from the true temperature, namely, the target temperature obtained at the beginning is according to the following conditionsIt is calculated to have an error from the actual target temperature, and the empirical value of this error is obtained by Δt=k (Δv max-ΔVmin). Therefore, at the time of correction, the final corrected temperature=target temperature+temperature compensation value plus Δt.
It can be understood that in the embodiment of the application, the temperature rise relation among the plurality of sensors in the thermometer is established, and meanwhile, the temperature rise rate of the plurality of sensors is taken as a reference, and a correction formula of the temperature compensation value is established to correct the target temperature, so that more accurate temperature data can be obtained, and the accuracy and stability of temperature measurement are improved.
