Specifically, when the transfer unit is configured to screen the temperature data in the repository and establish a normal temperature data set and an abnormal temperature data set according to a screening result, the transfer unit includes:
dividing the temperature data in the repository according to a time period;
Calculating variances of all temperature data in the same time period, comparing the variances with a preset variance threshold, and judging according to comparison results;
temporarily adding all temperature data within the same time period to the normal temperature dataset when the variance is less than or equal to the variance threshold;
when the variance is greater than the variance threshold, adding all temperature data within the same time period to the abnormal temperature dataset.
Specifically, when the variance is less than or equal to the variance threshold, after temporarily adding all the temperature data in the same time period to the normal temperature data set, the method further includes:
And presetting a temperature standard value, then carrying out difference on all the temperature data in the same time period with the temperature standard value one by one to obtain a third difference value, comparing the third difference value with a preset third difference value threshold value, and judging whether to transfer the temperature data into the abnormal temperature data set according to a comparison result.
Specifically, comparing the third difference value with a preset third difference value threshold, and judging whether to transfer the temperature data into the abnormal temperature data set according to the comparison result, wherein the method comprises the following steps:
When the third difference is less than or equal to the third difference threshold, retaining the temperature data to the normal temperature dataset;
And when the third difference value is greater than the third difference value threshold value, transferring the temperature data into the abnormal temperature data set.
It can be seen that, in order to further enhance the flexibility and accuracy of the temperature sensor data recording system in this embodiment, the screening mechanism of the transit unit is refined and optimized, in addition to the basic screening based on the variance of the temperature data in the time period, a temperature standard value is introduced to achieve finer data classification, after temporarily classifying all the temperature data in a certain time period into a normal temperature data set, the system does not stop further evaluation of the data immediately, instead, it compares the data with a preset temperature standard value, which may be an average value obtained based on statistical analysis of historical data, a median value or a fixed value set according to a specific application scenario, the normality of each temperature data can be evaluated more accurately by calculating the difference (i.e. the third difference) between each temperature data and the standard value, if the third difference between a certain temperature data and the standard value exceeds the preset third difference threshold, even if it is classified as normal temperature data, the system will evaluate again the attribution the normal temperature data set and possibly transfer it from the normal temperature data set to the abnormal temperature data set, which enables the system to recognize that the whole does not deviate significantly from the normal data points, although the fluctuation is not significantly detected.
Specifically, the determining unit is further configured to calculate a first difference between the temperature data in the abnormal temperature data set and the average temperature value, compare the difference with a preset first difference threshold, and determine, according to a comparison result, an abnormal level of the temperature data, where the determining unit includes:
The first difference threshold includes a first lowest difference threshold and a first highest difference threshold;
When the first difference value is smaller than or equal to the first lowest difference value threshold value, judging that the abnormal grade of the temperature data is a first grade;
When the first difference value is larger than the first lowest difference value threshold value and smaller than or equal to the first highest difference value threshold value, judging that the abnormal grade of the temperature data is a second grade;
when the first difference value is larger than the first highest difference value threshold value, judging that the abnormal grade of the temperature data is a third grade;
Wherein the first level is less than the second level and the second level is less than the third level.
It can be seen that in the process of judging the abnormal level of the optimized temperature data, the judging unit adopts a finer grading strategy, and by setting a plurality of difference thresholds (namely a first lowest difference threshold and a first highest difference threshold), the more accurate quantitative evaluation of the abnormal temperature data is realized.
It will be appreciated that when the difference between certain temperature data and the baseline (i.e., average temperature value) falls within a first minimum difference threshold, the system determines that the data is a slight anomaly, i.e., a first level anomaly, which may represent some temporary temperature change that has little impact on the system as a whole, such as a brief environmental factor fluctuation, when the difference exceeds the first minimum difference threshold but is still within the first maximum difference threshold, the system determines a moderate anomaly, i.e., a second level anomaly, which may indicate some trend of temperature change that requires attention, or may be an early signal that the system is about to face a potential problem, and when the difference exceeds the first maximum difference threshold, the system determines a severe anomaly, i.e., a third level anomaly, which may be a direct impact on the normal operation or safety performance of the device, for which the system should trigger an alarm immediately and initiate a corresponding emergency treatment procedure automatically or manually to ensure the stability and safety of the system.
Specifically, the processing unit is configured to calculate, after determining the abnormal level of the temperature data, a temperature fluctuation value of the temperature data in the abnormal temperature data set and the corresponding historical time temperature data, and calculate a second difference value between the temperature fluctuation value and the maximum temperature fluctuation value, where the second difference value includes:
The historical time temperature data are corresponding historical time temperature data in the same time period, and the maximum temperature fluctuation value is the difference value between the maximum temperature data and the minimum temperature data in the normal temperature data set.
Specifically, when the abnormal level of the temperature data is adjusted according to the relation between the second difference value and a preset second difference value threshold value, the method includes:
The second difference threshold includes a second lowest difference threshold and a second highest difference threshold;
when the second difference value is smaller than or equal to the second lowest difference value threshold value, reducing the abnormal grade of the temperature data;
when the second difference value is larger than the second lowest difference value threshold value and smaller than or equal to a second highest difference value threshold value, maintaining the abnormal level of the current temperature data unchanged;
And when the second difference value is larger than the second highest difference value threshold value, the abnormal grade of the temperature data is adjusted to be high.
Specifically, when the processing unit determines to lower the abnormality level of the temperature data, it includes:
When the second difference value is smaller than or equal to the second lowest difference value threshold value, the second lowest difference value threshold value and the second difference value are subjected to difference to obtain a fourth difference value;
comparing the fourth difference value with a preset fourth difference value threshold value, and adjusting the abnormal level of the temperature data according to the comparison result;
When the fourth difference value is smaller than or equal to the fourth difference value threshold value, determining that the abnormal level of the temperature data is reduced by two stages;
When the fourth difference value is larger than the fourth difference value threshold value, determining that the abnormal level of the temperature data is lowered by one level;
wherein the lowest of the abnormal levels of the temperature data is adjusted to the first level.
Specifically, when the processing unit determines to raise the abnormality level of the temperature data, it includes:
When the second difference value is larger than the second highest difference value threshold value, the second highest difference value threshold value and the second difference value are subjected to difference to obtain a fifth difference value;
Comparing the fifth difference value with a preset fifth difference value threshold value, and adjusting the abnormal level of the temperature data according to the comparison result;
when the fifth difference value is smaller than or equal to the fifth difference value threshold value, determining that the abnormal level of the temperature data is increased by one level;
When the fifth difference value is larger than the fifth difference value threshold value, determining that the abnormal level of the temperature data is increased by two stages;
wherein the highest of the abnormal levels of the temperature data is tuned to the third level.
It can be seen that in the process of further refining abnormal processing of temperature data, the system not only judges the abnormal grade through the difference threshold value, but also introduces the consideration of the temperature fluctuation value, thereby realizing accurate capture of the dynamic change of the abnormal state.
It will be appreciated that when the temperature data calculated by the processing unit is compared with the temperature fluctuation value of the temperature data at the historical moment, and is thus compared with the maximum temperature fluctuation value, the deviation degree of the current temperature state relative to the historical normalcy is actually evaluated, if the deviation degree is small (namely, the second difference value is lower than the second lowest difference value threshold value), the former abnormal judgment is too sensitive, or the current temperature state is returning to the normal state, so that the system can choose to adjust the abnormal grade of the temperature data, the adjustment not only helps to reduce false alarms, but also enables the system to adapt to the change of the environment more flexibly, otherwise, when the temperature fluctuation value is obviously increased (namely, the second difference value exceeds the second highest difference value threshold value), the system can regard the change as an abnormal signal, and then adjust the abnormal grade of the temperature data, the timely reaction can ensure that the system can rapidly start the emergency measure of a higher level when facing the emergency situation, and thus effectively preventing the expansion of the potential problem.
It can be understood that when the processing unit adjusts the abnormal level, the fourth and fifth difference values and the fourth and fifth difference threshold values corresponding to the fourth and fifth difference values are compared, so that the system can finely control the adjustment amplitude of the abnormal level according to the specific magnitude of the temperature fluctuation value, for example, when the temperature fluctuation value deviates from the normal range extremely (i.e. the fourth or fifth difference value is far greater than the corresponding threshold value), the system can select to adjust up or down the two-stage abnormal level at one time so as to adapt to the change of the temperature state more quickly, and the step adjustment strategy not only improves the response speed of the system, but also enables the abnormal processing process to meet the requirements of practical situations more.
Referring to fig. 2, in some embodiments of the present application, a data recording method for a temperature sensor is provided, including the steps of:
s100, acquiring temperature data of a temperature sensor in real time, and storing the temperature data into a storage library;
S200, screening the temperature data in the storage library, and establishing a normal temperature data set and an abnormal temperature data set according to a screening result;
s300, calculating an average temperature value and a maximum temperature fluctuation value of the temperature data in the normal temperature data set, calculating a first difference value between the temperature data and the average temperature value in the abnormal temperature data set, comparing the first difference value with a preset first difference value threshold, and judging the abnormal grade of the temperature data according to a comparison result;
s400, after determining abnormal grades of the temperature data, calculating temperature fluctuation values of the temperature data in the abnormal temperature data set and corresponding historical moment temperature data, calculating a second difference value between the temperature fluctuation values and the maximum temperature fluctuation value, and then adjusting the abnormal grades of the temperature data according to the relation between the second difference value and a preset second difference value threshold;
And S500, storing and recording the adjusted temperature data according to the abnormal grade.
