and converting the inside of the three-dimensional curved surface into a two-dimensional array, wherein the two-dimensional array comprises a plurality of array elements formed by basic arrays, and the two-dimensional array is used as a humidity comparison table.
TABLE 1 two-dimensional array (temperature-humidity-voltage value)
In order to simplify the relationship between data, a data processor performs a programming process on a three-dimensional curved surface, and the three-dimensional curved surface is converted into a two-dimensional array including a plurality of temperature sample data, a plurality of humidity sample data, and a plurality of humidity sample partial pressure data, which are corresponding to each other, for example, the two-dimensional array obtained according to the three-dimensional curved surface may be as shown in table 1, the two-dimensional array includes a primary index value, a secondary index value, and a group value, for example, in this embodiment, as shown in table 1, the temperature in the table is the temperature sample data, the temperature sample data may be used as the primary index value, the relative humidity in the table is the humidity sample data, the humidity sample data may be used as the secondary index value, the voltage value in the table is the humidity sample partial pressure data, the humidity sample partial pressure data may be used as the group value of the two-dimensional array, and the table content may be adjusted according to actually detected data, and is not particularly limited herein. The other value can be obtained through any two values of the first-level index value, the second-level index value and the array value, and therefore rapid data query is achieved.
In some embodiments of the present application, as shown in fig. 6, converting the inside of the three-dimensional curved surface into a two-dimensional array, where the two-dimensional array includes a plurality of array elements composed of basic arrays, includes the following steps 301 to 303:
301. and determining a first-level index value of the basic array according to the temperature sample data.
The first-level index value of the basic array may be any one of temperature sample data, humidity sample data, or humidity sample partial pressure data.
In the application process, the detected temperature partial pressure value is constantly changed according to the temperature change of the space to be detected, so that the table look-up process of the data processor needs to frequently inquire the current humidity data, and the current relative humidity data of the space to be detected constantly generates data fluctuation.
Therefore, in an embodiment, determining the first-level index value of the base array according to the temperature sample data includes:
dividing N temperature sample data with adjacent values in the plurality of temperature sample data into a temperature data interval to obtain a plurality of temperature data intervals, wherein N is a natural number smaller than 4.
In this embodiment, N is set to 3, that is, 3 temperature sample data with adjacent values in the plurality of temperature sample data are divided into one temperature data interval, for example, as shown in table 1, three data with temperature sample data of 5, 6, and 7 are taken as one temperature data interval, and so on, a plurality of temperature data intervals covering more temperature sample data are obtained, and since the change of the humidity voltage relationship between each adjacent temperature sample data of the plurality of temperature sample data is slight, the error can still be made to be less than or equal to 1%, and the accuracy is not lost.
And marking the temperature data intervals in sequence to obtain a plurality of temperature data intervals with numerical marks, and determining a first-level index value of the numerical mark as a basic array.
In order to facilitate the data processor to look up the table, the corresponding temperature data interval may be labeled, so that after the data processor obtains the actually measured current temperature data, the corresponding temperature data interval is determined according to the current temperature data, and the numerical label corresponding to the temperature data interval is obtained, i.e., the primary index value can be determined.
302. And determining a secondary index value of the basic array according to the humidity sample data.
The second-level index value of the basic array may be any one of temperature sample data, humidity sample data, or humidity sample partial pressure data.
Specifically, since the first-level index value is a temperature data interval, according to the corresponding relationship between the humidity sample data and the temperature sample data in the three-dimensional curved surface, the temperature data interval is formed by 3 temperature sample data whose data sizes are adjacent to each other, and the temperature data interval corresponds to 3 humidity sample data whose data values are the same or different in the three-dimensional curved surface, in order to facilitate the use of the basic array, in this embodiment, the average value of the 3 humidity sample data corresponding to the temperature data interval is calculated, and the average value of the obtained 3 humidity sample data is used as the second-level index value of the basic array.
Therefore, according to the humidity sample data, determining a secondary index value of the base array comprises the following steps:
and determining N humidity sample data corresponding to the N temperature sample data in the temperature data interval according to the temperature data interval.
In this embodiment, if the temperature data interval is 3 temperature sample data, it is determined that 3 humidity sample data correspond to the temperature data interval. For example, when the temperature data interval is 5 to 7 ℃, in the temperature data interval, if the actual measured partial pressure data of the humidity sample is 3.51V, the corresponding 3 humidity sample data are 87% RH, 86% RH, and 85% RH.
And carrying out average calculation on the N humidity sample data to obtain humidity sample average data, and determining the humidity sample average data as a secondary index value of the basic array.
In this embodiment, if the temperature data interval is 5 to 7 ℃, and the 3 corresponding humidity sample data are 87% RH, 86% RH, and 85% RH, averaging the 3 humidity sample data, and the obtained average data of the humidity sample is 86% RH, the average data of the humidity sample with the value of 86% RH is determined as the secondary index value of the basic array. Therefore, in the application process, when the detected current temperature data is in a certain temperature data interval, the average data of the humidity sample is directly obtained in a table look-up mode, the current relative humidity data corresponding to the current temperature data can be obtained, the frequent table look-up of the switching interval due to the temperature change is prevented, and the obtained current relative humidity data can be more stable.
303. And determining array values of the basic arrays according to the partial pressure data of the humidity samples, and taking the two-dimensional arrays formed by the plurality of basic arrays as a humidity comparison table.
The array value of the basic array may be any one of temperature sample data, humidity sample data, or humidity sample partial pressure data, and in this embodiment, the array value of the basic array is determined according to the humidity sample partial pressure data.
TABLE 2 humidity comparison table (temperature-humidity-voltage value)

For example, the humidity comparison table may be as shown in table 2, or a comparison table as shown in fig. 7 may be obtained, and the table content is also adjusted according to the actually detected data, which is not limited herein.
In some embodiments of the present application, as shown in fig. 8, based on a preset humidity comparison table, looking up a table by using current temperature data and a humidity partial pressure value as inputs to obtain current relative humidity data in a space to be measured, including the following steps 401 to 403:
401. and determining a temperature data interval corresponding to the current temperature data in the humidity comparison table according to the current temperature data.
And after the current temperature data is acquired, the data processor determines the temperature data interval according to the current temperature data.
