As shown in fig. 2, the temperature and humidity detecting apparatus 200 includes N temperature and humidity sensors 201, a heat source 202, a human body sensing sensor 203, a processor 204, and a display unit 205.
And the temperature and humidity sensor 201 is configured to detect a measurement value of a first index of the current environment, and send the detected measurement value of the first index of the current environment to the processor. Wherein the first indicator comprises temperature and/or humidity.
It should be noted that, the number and the position of the temperature and humidity sensors in the temperature and humidity detection device are not limited in the present application.

FIG. 4 is a schematic flowchart illustrating a method for processing a measured value of a first index according to an embodiment of the present disclosure;
the processor shown in fig. 4 is configured to perform the following processing on the measured value of the first index detected by the temperature and humidity sensor:
step 401, obtaining measurement values of first indexes of N temperature and humidity sensors in the detection device and a temperature value of a heat source.
And 402, determining an influence coefficient of the heat source on the temperature and humidity sensor according to the temperature value of the heat source and the distance between the heat source and the temperature and humidity sensor for each temperature and humidity sensor.
In a possible implementation mode, when the temperature and humidity detection equipment leaves a factory, a fixed temperature influence coefficient alpha is set according to a temperature value range when a heat source works; according to the distance between the heat source and each temperature and humidity sensor, setting the distance influence coefficient x of the heat source to each temperature and humidity sensor n . According to the temperature influence coefficient alpha and the distance influence coefficient x n Obtaining the influence coefficient alpha/x of the heat source to the temperature and humidity sensor n 。
In another possible embodiment, since the influence degree of the heat source on the measured value of the temperature and humidity sensor is influenced by the temperature value of the heat source itself, the higher the temperature value of the heat source, the greater the influence degree on the measured value of the temperature and humidity sensor. In contrast, when the temperature and humidity measurement device is shipped from the factory, a plurality of temperature value intervals may be set within the temperature value range during operation of the heat source, and one temperature influence coefficient α may be set for each temperature value interval n (ii) a According to the distance between the heat source and each temperature and humidity sensor, setting the distance influence coefficient x of the heat source to each temperature and humidity sensor n . According to the temperature influence coefficient alpha n And the distance influence coefficient x n Obtaining the influence coefficient alpha of the heat source to the temperature and humidity sensor n /x n 。
And step 403, determining a corrected value of the first index of the temperature and humidity sensor according to the measured value of the first index of the temperature and humidity sensor and the influence coefficient of the heat source on the temperature and humidity sensor.
E.g. correction value of temperature t n ＝t n -α/x n * T, corrected value of humidity is RH n '＝RH n +α/x n *T。
And step 404, taking the weighted average value of the correction values of the first indexes of the N temperature and humidity sensors as the display value of the first index of the detection equipment.
In the above step, in calculating the weighted average value, the weighting coefficient of the correction value of each first index may be obtained by: and determining a weighting coefficient corresponding to each temperature and humidity sensor according to the position of the temperature and humidity sensor in the detection equipment and the distance between the temperature and humidity sensor and the heat source. After the weighting coefficient corresponding to each temperature and humidity sensor is determined, calculating a weighted average value of the correction values of the first indexes of the N temperature and humidity sensors according to the weighting coefficient corresponding to each temperature and humidity sensor and the correction value of the first index of each temperature and humidity sensor, wherein the sum of the weighting coefficients of each temperature and humidity sensor is 1 when the weighted average is calculated.
For example, as shown in fig. 5, 4 temperature/humidity sensors a are provided in the temperature/humidity detection device 1 、A 2 、A 3 、A 4 For example, the processing procedure of the processor for the measured value of the first index detected by the temperature and humidity sensor is illustrated. Wherein, the temperature and humidity sensor A 1 、A 2 、A 3 、A 4 The distance from the heat source is x respectively 1 、x 2 、x 3 、x 4 。
Step one, acquiring 4 temperature and humidity sensors A in detection equipment 1 、A 2 、A 3 、A 4 Measured value t of temperature of 1 、t 2 、t 3 、t 4 Humidity measurement value RH 1 、RH 2 、RH 3 、RH 4 And a temperature value T of the heat source.
Step two, determining the temperature and humidity sensor A of the heat source according to the temperature value T of the heat source and the distance between the heat source and the temperature and humidity sensor 1 、A 2 、A 3 、A 4 Respectively is alpha/x 1 、α/x 2 、α/x 3 、α/x 4 。
Thirdly, determining the temperature and humidity sensors A according to the measured values of the temperature and the humidity of each temperature and humidity sensor and the influence coefficient of the heat source for each temperature and humidity sensor 1 、A 2 、A 3 、A 4 The corrected values of the temperatures of (a) are: t is t 1 '＝t 1 -α/x 1 *T；t 2 '＝t 2 -α/x 2 *T；t 3 '＝t 3 -α/x 3 *T；t 4 '＝t 4 -α/x 4 * T; the corrected values of the humidity of the temperature and humidity sensor are respectively as follows: RH (relative humidity) 1 '＝RH 1 +α/x 1 *T；RH 2 '＝RH 2 +α/x 2 *T；RH 3 '＝RH 3 +α/x 3 *T；RH 4 '＝RH 4 +α/x 4 *T。
Step four, calculating to obtain the weighted average temperature t = z of the 4 temperature and humidity sensors 1 *t 1 '+z 2 *t 2 '+z 3 *t 3 '+z 3 *t 3 '; weighted average humidity RH = z 1 *RH 1 '+z 2 *RH 2 '+z 3 *RH 4 '+z 3 *RH 4 '. Wherein z is 1 + 2 +z 3 +z 4 =1. The weighted average temperature of the 4 temperature and humidity sensors is used as the display value of the temperature of the detection equipment, and the weighted average humidity is used as the display value of the humidity of the detection equipment.
In some embodiments, the processor is further configured to keep the main temperature and humidity sensor in an on state all the time within a first preset time period, turn on one of the auxiliary temperature and humidity sensors within each second preset time period within the first preset time period, and keep a display value of the first indicator unchanged if an absolute value of a difference between a measurement value of the first indicator of the main temperature and humidity sensor and a display value of the first indicator of the auxiliary temperature and humidity sensor is smaller than a first set threshold.
And if the absolute value of the difference between the measured value of the first index of the main temperature and humidity sensor and the displayed value of the first index of the auxiliary temperature and humidity sensor is larger than a first set threshold, re-acquiring the measured values of the first index of the N temperature and humidity sensors and the temperature value of the heat source, and re-calculating the displayed value of the first index.
The main temperature and humidity sensor is one of N sensors, the auxiliary temperature and humidity sensor is a temperature and humidity sensor except the main temperature and humidity sensor in the N temperature and humidity sensors, and the first set threshold is the maximum value in the absolute values of the difference between the measured value of the first index of each temperature sensor and the display value of the first index.

Step 602, judging whether the absolute value of the difference value of the measured values of the main sensor and the auxiliary sensor is larger than a first set threshold value; if yes, go to step 601; if not, go to step 603.
Step 603, keeping the display value of the first index unchanged.

And if the absolute values of the difference values between the measured values of the first indexes of the main temperature and humidity sensor and the display values of the first indexes of the auxiliary temperature and humidity sensor are smaller than a first set threshold, keeping the display values of the first indexes unchanged until a second preset time period is finished. And after a second preset time period is finished, sequentially starting another auxiliary temperature and humidity sensor, and similarly enabling other auxiliary temperature and humidity sensors to be in a closed state. The absolute value of the difference between the measured value of the first index of the main sensor and the displayed value is compared, and the relation between the absolute value of the difference between the measured value of the first index of the turned-on auxiliary sensor and the displayed value and the first threshold value is obtained.
And if the absolute value of the difference between the measured value of the first index of the main temperature and humidity sensor and the displayed value of the first index of the auxiliary temperature and humidity sensor is larger than a first set threshold, re-acquiring the measured values of the first index of the N temperature and humidity sensors and the temperature value of the heat source, and re-calculating the displayed value of the first index.

And after a first preset time period is finished, entering the next first preset time period, replacing the main sensor, and switching the auxiliary sensors in turn.
And comparing the absolute value of the difference between the measured value of the first index of the main sensor and the displayed value and the relation between the absolute value of the difference between the measured value of the first index of the turned-on auxiliary sensor and the displayed value and the first threshold value in each second preset time period. If the absolute value of the difference between the measured value of the first index of the main temperature and humidity sensor and the displayed value of the first index of the auxiliary temperature and humidity sensor is smaller than a first set threshold, the variation of the measured value at the moment is smaller, and the displayed value of the first index is kept unchanged.
If the absolute value of the difference between the measured value of the first index of the main temperature and humidity sensor and/or the auxiliary temperature and humidity sensor and the displayed value of the first index is larger than a first set threshold, the variation of the measured value at the moment is large, the measured value of the first index of the N temperature and humidity sensors and the temperature value of the heat source need to be obtained again, and the displayed value of the first index needs to be calculated again.
Taking the example that 4 temperature and humidity sensors A1, A2, A3, and A4 are arranged in the temperature and humidity detection device, and the first index is a temperature index, a determination process of the processor for a measurement value of the first index detected by the temperature and humidity sensor and a set threshold is illustrated.
And starting temperature and humidity detection equipment, wherein all sensors are turned on in an H0 time period, and measuring values tA1, tA2, tA3 and tA4 of the temperatures of 4 temperature and humidity sensors A1, A2, A3 and A4 in the detection equipment and a temperature value T of a heat source are obtained. The process of the measured temperature value is the same as the process of the above embodiment, and the displayed temperature value t1 is obtained.
The absolute values of the differences between the measured values t1, t2, t3, t4 of the temperatures of the 4 temperature/humidity sensors A1, A2, A3, A4 and the display value t are calculated, and the absolute value of the maximum value of the absolute values of the differences is set as a first set threshold A1 of the temperature.
Case 1, as shown in fig. 7:
in the H2-1 time period, A1 is set as a main temperature and humidity sensor, and A2, A3 and A4 are set as auxiliary temperature and humidity sensors. Wherein, main temperature and humidity sensor A1 is in the open mode always, and supplementary temperature and humidity sensor A2, A3, A4 open in turn.
In the time period H1-1, the auxiliary temperature and humidity sensor A2 is turned on, the A3 and the A4 are turned off, if the absolute value of the difference between the temperature measurement values tA1 and tA2 of the main temperature and humidity sensor A1 and the temperature display value t1 is always smaller than a first set threshold value A1, namely | tA1-t1| < A1 and | tA2-t1| < A1, the temperature display value t1 is kept unchanged until the time period H1-1 is ended, and the time period H1-2 is entered.
In the H1-2 time period, the auxiliary temperature and humidity sensor A3 is turned on, A2 and A4 are turned off, if the absolute value of the difference between the measured values tA1 and tA3 of the temperatures of the main temperature and humidity sensor A1 and the auxiliary temperature and humidity sensor A3 and the display value t1 of the temperatures is smaller than a first set threshold value A1, namely | tA1-t1| < A1 and | tA3-t1| < A1, the display value t1 of the temperatures is kept unchanged until the H1-2 time period is ended, and the H1-3 time period is entered.
And starting the auxiliary sensors A2, A3 and A4 in a time period of H2-1 by the wheel flow, and repeatedly executing the steps, wherein if the absolute value of the difference between the temperature measured values of the main temperature and humidity sensor and the auxiliary temperature and humidity sensor and the temperature display value t1 is smaller than a first set threshold value a1, the temperature display value t1 is kept unchanged until the time period of H2-1 is ended, and entering the time period of H2-2.
In the H2-2 time period, A2 is set as a main sensor, and A1, A3 and A4 are set as auxiliary sensors. Wherein, main temperature and humidity sensor A2 is in the open mode always, and supplementary temperature and humidity sensor A2, A3, A4 open in turn.
And (3) turning on the auxiliary sensors A1, A3 and A4 in turn in the H2-2 time period, and repeatedly executing the steps, wherein if the absolute value of the difference between the temperature measured values of the main temperature and humidity sensor and the auxiliary temperature and humidity sensor and the temperature display value t1 is smaller than a first set threshold value A1, keeping the temperature display value t1 unchanged until the H2-2 time period is ended, and entering the H2-3 time period.
Case 2, as shown in fig. 8:
in the H2-1 time period and the H1-1 and H1-2 time periods in the H2-2 time period, the absolute value of the difference value between the temperature measured value of the main temperature and humidity sensor and the temperature displayed value t1 of the auxiliary temperature and humidity sensor is always smaller than a first set threshold value a1, and then the temperature displayed value t1 is always kept unchanged.
In the H1-3 time period, at a certain moment, the absolute value of the difference between the temperature measured values of the main temperature and humidity sensor A2 and the auxiliary temperature and humidity sensor A4 and the temperature display value T1 is greater than the first set threshold value A1, then in the H0 time period, all the temperature and humidity sensors are turned on, and the temperature measured values tA1, tA2, tA3, tA4 of the temperatures of the 4 temperature and humidity sensors A1, A2, A3, A4 in the detection device and the temperature value T of the heat source are obtained again. And calculates a displayed value t2 of the temperature and a first set threshold value a2 of the temperature.
After recalculating the display value t2 of the temperature and the first set threshold A2 of the temperature, if the display value is still within the H1-3 time period, the temperature sensor still uses A2 as the main temperature and humidity sensor, and A1, A3 and A4 as the auxiliary temperature and humidity sensors. The main temperature and humidity sensor A2 is always in an on state, the auxiliary temperature and humidity sensor A2 is turned on, A3 and A4 are turned off, and the magnitude relation between the absolute value of the difference between the measured values tA2 and tA4 of the temperatures of the main temperature and humidity sensor A2 and the auxiliary temperature and humidity sensor A4 and the displayed value t2 of the temperatures and the first set threshold value A2 is judged.
If the absolute values of the difference values between the measured values tA2 and tA4 of the temperatures of the main temperature and humidity sensor A2 and the auxiliary temperature and humidity sensor A4 and the displayed value t2 of the temperatures are always satisfied within the remaining H1-3 time period and are smaller than a first set threshold value A2, namely | tA2-t2| < a1 and | tA4-t2| < a1, the displayed value t2 of the temperatures is kept unchanged until the H1-3 time period is ended, and the H1-4 time period is entered.
In some embodiments, the processor is further configured to keep the main temperature and humidity sensor in an on state all the time within a first preset time period, and turn on one of the auxiliary temperature and humidity sensors within each of second preset time periods within the first preset time period.
And if the absolute value of the difference value between the measured value of the first index of the main temperature and humidity sensor and the display value of the first index of the auxiliary temperature and humidity sensor is smaller than a first set threshold value, keeping the display value of the first index unchanged.
And if the absolute value of the difference between the measured value of the first index of the main temperature and humidity sensor and/or the auxiliary temperature and humidity sensor and the displayed value of the first index is judged to be larger than the first set threshold and smaller than the second set threshold, the measured values of the first index of the N temperature and humidity sensors and the temperature value of the heat source are obtained again, and the displayed value of the first index is calculated.
And if the absolute value of the difference between the measured value of the first index of the main temperature and humidity sensor and/or the auxiliary temperature and humidity sensor and the displayed value of the first index is judged to be larger than the second set threshold, the measured value of the second index is considered to be abnormal, the N temperature and humidity sensors are started, and the reason for the abnormal measured value of the first index is judged according to the measured value of the first index of the N temperature and humidity sensors.
The reasons for the abnormal measurement value of the first index include the influence of human factors, such as the influence of heat generated by breathing when a person approaches the sensor on the measurement value of the first index, or the reasons of the temperature and humidity sensor, such as the abnormal measurement value of the first index caused by the damage of the sensor.
And if the absolute value of the difference value of any two temperature and humidity sensors is judged to be larger than the third set threshold value and the human body perception sensor identifies a person, keeping the display value of the first index unchanged.
In the above technical solution, if it is determined that the absolute value of the difference between any two temperature and humidity sensors is greater than the third set threshold, and the human body sensing sensor identifies a human, the measured value abnormality of the first index is affected by human factors, for example, the measured value is affected by heat generated by breathing when the human approaches the temperature and humidity detection device. But in this case the actual temperature and humidity values of the environment are unchanged. It is therefore necessary to keep the displayed value of the first index unchanged. And during the period, a pop-up window can be displayed on the display interface to prompt the user of historical detection data (for example, a curve displaying historical temperature and humidity) and real-time temperature values and humidity values influenced by human factors for the reference of the user. For example, the maximum value of the measurement value of the first index of the temperature and humidity sensor may be displayed on the display interface as real-time data affected by human factors.
When the human body perception sensor recognizes that a person leaves, the measured values of the first indexes of the N temperature and humidity sensors and the temperature value of the heat source are obtained again, and the display value of the first indexes is calculated again.
If the absolute value of the difference between the measured value of the first index of the first temperature and humidity sensor and the displayed value of the first index is larger than the fourth set threshold, the measured value abnormality of the first index is the measured value abnormality caused by the self reason of the sensor, the measured values of the first indexes of the N temperature and humidity sensors and the temperature value of the heat source are obtained again, the measured value of the first index of the first temperature and humidity sensor is eliminated, and the displayed value of the first index is calculated again.
In addition, the temperature and humidity sensor can be marked when the detection value of the first index of the temperature and humidity sensor is abnormal every time, when the mark exceeds a certain value, the temperature and humidity sensor is considered to be invalid, and the measurement data of the temperature and humidity sensor is not used any more subsequently.
The second set threshold, the third set threshold, and the fourth set threshold may be set at the time of factory shipment of the temperature and humidity detection apparatus, or may be set by a user. Normally, the magnitude relationship of the threshold is such that the third set threshold is smaller than the second set threshold is smaller than the fourth set threshold.

As shown in fig. 9, the method comprises the following steps:
step 901, obtaining measurement values of first indexes of the N temperature and humidity sensors and a temperature value of a heat source, and calculating a display value of the first index and a first set threshold.

Step 905, judging whether the absolute value of the difference value of the measured values of any two sensors is greater than a third set threshold value; if yes, go to step 906; if not, go to step 901.
Step 906, judging that the human body perception sensor identifies a human body; if yes, go to step 907; if not, go to step 901.
Step 907, keep the display value of the first index unchanged.
The displayed value of the first indicator is maintained and step 906 is repeated.
Step 908 the displayed value of the first index is kept unchanged.
Step 909, judging whether the absolute value of the difference between the measurement value of any sensor and the display value is greater than a fourth set threshold; if yes, go to step 910; if not, go to step 901.
And step 910, removing the abnormal value, and recalculating the display value of the first index.
