At present, the temperature measured by the temperature measuring instrument is easy to generate errors. The cause of the error is several. For example, the effect of ambient temperature; for another example, the operation is not standard and scientific; like some operators are far away from the forehead during operation, and some operators are close to the forehead during operation, the measured temperature has an error under the condition; for another example, the system is repeatedly used for a long time, resulting in rapid aging of the internal sensing device.
In order to solve the problems, the invention provides a temperature measuring method, a cloud server and a temperature measuring instrument, wherein after the measured temperature in the latest period of time sent by the temperature measuring instrument is obtained, the temperature record corresponding to the period of time in a database is determined, then the zeroing temperature is determined according to the measured temperature sent by the temperature measuring instrument and the obtained temperature record, and then the temperature measured by the temperature measuring instrument is corrected through the zeroing temperature, so that the problems of inaccurate measured temperature caused by non-standard operation and environmental factors in the prior art are solved, and the accuracy of temperature measurement can be improved through the temperature measuring instrument.
The following embodiments can be applied to the temperature measuring system shown in fig. 1, where the system shown in fig. 1 includes a cloud server 10, and at least one temperature measuring instrument 20 communicatively connected to the cloud server 10.

The invention provides a temperature measuring system.A cloud server acquires M measured temperatures sent by a temperature measuring instrument, and measurement starting time To and measurement ending time Te corresponding To the M measured temperatures; then K temperature records of a time period corresponding To the measurement starting time To and the measurement ending time Te in a database of the cloud server are determined; judging whether K is greater than or equal to a preset recording threshold value; if K is larger than or equal to a preset recording threshold value, determining the zero calibration temperature according to the M measured temperatures and the K temperature records; and sending the zero calibration temperature to the temperature measuring instrument so that the temperature measuring instrument obtains the display temperature according to the sum of the calculated actual measured temperature and the zero calibration temperature. The method and the device have the advantages that after the measured temperature in the latest period of time sent by the temperature measuring instrument is obtained, the temperature record corresponding to the period of time in the database is determined, then the zero calibration temperature is determined according to the measured temperature sent by the temperature measuring instrument and the obtained temperature record, and then the temperature measured by the temperature measuring instrument is calibrated through the zero calibration temperature, so that the problems of inaccurate measured temperature caused by non-standard operation and environmental factors in the prior art are solved, and the accuracy of temperature measurement is improved through the method and the device.
Referring to fig. 2, a temperature measurement method according to a first embodiment of the present invention is shown, which can be applied to a cloud server in the temperature measurement system. Wherein, the temperature measuring system can realize the method through hardware and/or software, and the method specifically comprises steps S01-S04.
S01, obtaining M measured temperatures sent by the temperature measuring instrument and the measurement starting time To and the measurement ending time Te corresponding To the M measured temperatures.
The format of data transmitted to the server by the temperature measuring instrument is as follows: thermometer ID, To, Te, M, (T1, T2. Wherein T1-TM are M specific stored measured temperatures, the measurement start time To is the time when the temperature measuring instrument measures the first measured temperature of the M measured temperatures, and the measurement end time Te is the time when the temperature measuring instrument measures the last measured temperature of the M measured temperatures. That is, the present embodiment acquires M measurement temperatures measured by the temperature measuring instrument over the time period To-Te.
It should be noted that, before uploading the data to the cloud server, the temperature measurement instrument may perform data cleaning and calibration on the measured temperature. For example, a temperature measurement of 45 degrees celsius clearly exceeds the highest possible human temperature, and thus the data is rejected as contributing data. Conventional data cleaning and proofreading methods can be applied to the present invention, and the embodiments of the present invention are not described herein again.
In an embodiment of the present invention, the acquiring M measured temperatures sent by the temperature measuring instrument and the measurement start time To and the measurement end time Te corresponding To the M measured temperatures includes:
1. when the temperature measuring instrument determines that the number of the stored measured temperatures is larger than a first preset value, receiving M measured temperatures sent by the temperature measuring instrument, and measurement starting time To and measurement ending time Te corresponding To the M measured temperatures; or
The first preset value and the second preset value are preset temperature sample number thresholds, the first preset value is greater than the second preset value, and the sizes of the first preset value and the second preset value may be specifically set according to actual requirements.
Specifically, the temperature storage unit of the temperature measuring instrument further stores the earliest temperature measuring time, i.e., the earliest timestamp To of the stored (measured temperature, timestamp) pairs. The execution of the embedded computer program by the embedded processor has achieved the following steps:
s100, acquiring a measured temperature Tnew detected by the temperature detection unit in real time and a timestamp Ts of the detected temperature.
S200, the number m of (measured temperature, time stamp) pairs stored in the temperature storage unit is acquired.
S300, if M +1> is the first preset value D1, the temperature measuring instrument sends M (M +1) measured temperatures, and measurement starting time To and measurement ending time Te corresponding To the M measured temperatures To the cloud server.
2. And when the temperature measuring instrument determines that the number of the stored measured temperatures is larger than a second preset value and the measured density is smaller than a preset density threshold value, receiving M measured temperatures sent by the temperature measuring instrument, and measurement starting time To and measurement ending time Te corresponding To the M measured temperatures.
In the embodiment of the present invention, if m +1< > is equal To the first preset value D1, it is necessary To continuously determine whether m +1 is greater than the second preset value D2, and determine whether (m +1)/(Ts-To) is less than p; if it is determined that M +1> the second preset value D2 and (M +1)/(Ts-To) < p, the temperature measurement instrument sends M (M +1) measurement temperatures and measurement start times To and measurement end times Te corresponding To the M measurement temperatures To the cloud server. Wherein p is a preset temperature sample density threshold, which can be specifically set according to actual requirements.
If m +1< ═ D2 and (m +1)/(Ts-To) > p are determined, it is indicated that the storage unit has stored more sample samples and has passed through the sampling dense region, i.e., the sampling density starts To become sparse. At this point (Tnew, Ts) needs to be stored in the temperature storage unit until the number of stored (measured temperature, time stamp) meets the transmission requirements.
In one embodiment provided by the present invention, if m +1< ═ D2, and (m +1)/(Ts-To) < p, the embedded processor clears the pair of (measured temperature, timestamp) in the temperature storage unit. In this case, the data is discarded without any significance, because the sample size is not sufficient and the sample density is too high for the sampling period.
It should be noted that after the temperature measurement instrument uploads M measured temperatures, and the measurement start time To and the measurement end time Te corresponding To the M measured temperatures To the cloud server, the uploaded data in the temperature measurement needs To be deleted, so as To reduce the storage space caused by the temperature data.
And S02, determining K temperature records of the time period corresponding To the measurement starting time To and the measurement ending time Te in the database of the cloud server.
The database of the cloud server stores temperature records sent by the temperature measuring instrument, and each temperature record comprises a plurality of historical measuring temperatures. The format of each temperature record is: a thermometer ID, To, Te, M, (T1, T2.. said., TM), where T1-TM are the specific M stored measured temperatures. The cloud server stores the received data, so that loss of original data is avoided, and then the cloud server executes a computer program to realize the following steps:
s10, acquiring time period [ So, Se ] according To and Te. Specifically, To and Te are time stamps, the time stamps are with dates, and the corresponding time periods are obtained by removing the dates, so that the time periods are structures without dates, namely hour, minute and second.
S20, obtaining K temperature records from the database of the cloud server in the data stored in the cloud database, and enabling [ S0,Se]∩[Si0,Sie]Not equal to Null, the value of i is 1. Sio and Sie are the time periods for the earliest and latest timestamp acquisition in the ith record of the K temperature records.
It should be noted that, since the body temperature changes with different times every day, for example, the body temperature in the morning is higher than that in the afternoon, the embodiment of the present invention needs To determine K temperature records corresponding To the measurement start time To and the measurement end time Te, that is, in S0,Se]∩[Si0,Sie]When not equal To Null, it indicates that K temperature records of the time period corresponding To the measurement start time To and the measurement end time Te can be recorded from the database of the cloud server.
And S03, judging whether the K is more than or equal to a preset recording threshold value.
Wherein, the preset recording threshold value can be set according to the actual requirement, and when K is greater than or equal to the preset recording threshold value, the step S04 is skipped to continue to be executed; when K is smaller than a preset recording threshold, it is indicated that temperature records stored in a database summary of the cloud server are insufficient To determine the zeroing temperature, and at this time, the measurement start time To and the measurement end time Te corresponding To the M measurement temperatures received from the temperature measurement instrument need To be stored in the database, and the zeroing temperature is set To 0.
And S04, if the K is larger than or equal to a preset recording threshold value, determining the zero calibration temperature according to the M measured temperatures and the K temperature records.
In an embodiment of the present invention, determining the zeroing temperature according to the M measured temperatures and the K temperature records includes:
if it is determined
Setting the zeroing temperature to 0;
where a is a mean value of the M measured temperatures, Aj is a mean value of measured temperatures recorded in the jth record of the K temperature records, σ is a variance of Aj, and θ is a threshold determined according to a value of σ, and is, for example, 1. It should be noted that, in the case where the value of K is relatively large, the value of Aj should follow a normal distribution, so if a is relatively close to the average value of Aj, it indicates that a does not need to be corrected, that is, the thermometer does not need to be corrected, so the relatively zero temperature is set to 0.
In one embodiment provided by the present invention, if the determination is made
The method further comprises the following steps:
in determining
When the temperature of the water is higher than the set temperature,
in determining
When the temperature of the water is higher than the set temperature,
in another embodiment provided by the present invention, the determination
Whether the deviation value is larger than the preset deviation value or not. The preset offset value may be set according to an actual requirement, for example, the offset value is set to 3 degrees or 5 degrees, and the embodiment of the present invention is not limited specifically. In the embodiment of the invention, if the determination is made
If the deviation value is larger than the preset deviation value, it is indicated that the temperature average value corresponding to the current time period of the temperature measuring instrument and the temperature average value corresponding to the historical time period have larger deviation, and at this moment, the problem that the temperature measuring instrument has a fault may occur, so that prompt information needs to be sent to the temperature measuring instrument to prompt the temperature measuring instrument to be calibrated again.
And S05, sending the zero calibration temperature to the temperature measuring instrument, so that the temperature measuring instrument obtains a display temperature according to the sum of the calculated actual measured temperature and the zero calibration temperature.
In the embodiment of the invention, after the zero calibration temperature is sent to the temperature measuring instrument, the temperature measuring instrument obtains the display temperature according to the sum of the calculated actual measured temperature and the zero calibration temperature, and then the display of the temperature measuring instrument displays the display temperature obtained by calculation in real time for a user.
The invention provides a temperature measuring method, which comprises the steps of determining a temperature record corresponding to a time period in a database after obtaining a measured temperature sent by a temperature measuring instrument within the latest time period, then determining a zero calibration temperature according to the measured temperature sent by the temperature measuring instrument and the obtained temperature record, and then calibrating the temperature measured by the temperature measuring instrument through the zero calibration temperature, so that the problems of inaccurate measured temperature caused by non-standard operation and environmental factors in the prior art are solved, and the accuracy of temperature measurement can be improved through the temperature measuring method.

Wherein, the temperature measuring system can realize the method through hardware and/or software, and the method specifically comprises steps S10-S30.
S10, sending M measured temperatures, and measurement starting time To and measurement ending time Te corresponding To the M measured temperatures To the cloud server; and the cloud server acquires K temperature records of a time period corresponding To the measurement starting time To and the measurement ending time Te, and determines the zero calibration temperature according To the M measurement temperatures and the K temperature records.
The format of data transmitted to the server by the temperature measuring instrument is as follows: thermometer ID, To, Te, M, (T1, T2. Wherein T1-TM are M specific stored measured temperatures, the measurement start time To is the time when the temperature measuring instrument measures the first measured temperature of the M measured temperatures, and the measurement end time Te is the time when the temperature measuring instrument measures the last measured temperature of the M measured temperatures. That is, the present embodiment acquires M measurement temperatures measured by the temperature measuring instrument over the time period To-Te.
It should be noted that, in the embodiment of the present invention, the determination of K temperature records by the cloud server, and the determination of the zero calibration temperatures by the M measured temperatures and the K temperature records are the same as the determination in fig. 2, and no further description is given here in the embodiment of the present invention.
For the embodiment of the present invention, sending M measured temperatures, and the measurement start time To and the measurement end time Te corresponding To the M measured temperatures To the cloud server includes:

And S21, if the number of the stored measured temperatures is larger than a first preset value, sending M measured temperatures, and the measurement starting time To and the measurement ending time Te corresponding To the M measured temperatures To the cloud server.
S22, if the number of the stored measured temperatures is less than or equal to the first preset value, it is determined whether the number of the stored measured temperatures is greater than the second preset value and the measured density is less than the preset density threshold.
Step S21 is a parallel step of step S21. The first preset value and the second preset value are preset temperature sample quantity thresholds, the first preset value is greater than the second preset value, and the magnitudes of the first preset value and the second preset value may be specifically set according to actual requirements.
