The method for detecting the indoor temperature can be executed by a temperature sensor array, can be executed by a control terminal of an intelligent air conditioner or an intelligent home system, can also be executed by a family cloud platform, and can also be executed by the intelligent air conditioner.
Referring to fig. 2, the method for detecting the indoor temperature includes:
s201, when the indoor temperature is detected through a temperature sensor array arranged indoors, if a first temperature sensor of the temperature sensor array breaks down, first detection temperatures of a plurality of second temperature sensors adjacent to the first temperature sensor are obtained.
The temperature sensor array comprises a plurality of temperature sensors which are arranged in a vertical and horizontal mode.
If the first temperature sensor is at the non-edge of the temperature sensor array, 8 temperature sensors are adjacent to the first temperature sensor, wherein the distance between 4 temperature sensors and the first temperature sensor is a first distance, the distance between the other 4 temperature sensors and the first temperature sensor is a second distance, and the first distance is smaller than the second distance. In this scenario, first detection temperatures of 8 second temperature sensors are obtained; alternatively, the first detected temperatures of 4 second temperature sensors at a first distance from the first temperature sensor are obtained.
If the first temperature sensor is at the edge of the temperature sensor array and is not at the corner, 5 temperature sensors are adjacent to the first temperature sensor, wherein the distance between 3 temperature sensors and the first temperature sensor is a first distance, and the distance between the other 2 temperature sensors and the first temperature sensor is a second distance, wherein the first distance is smaller than the second distance. In this scenario, the first detected temperatures of the 5 second temperature sensors are obtained; or, the first detection temperature of 3 second temperature sensors at a first distance from the first temperature sensor is obtained.
S202, in a first preset temperature interval, determining a first temperature interval in which each first detection temperature is located.
The first preset temperature interval is a temperature interval divided in advance. For example, [5 ℃, 10 ℃ C.) is a temperature interval, [10 ℃, 15 ℃ C. is a second temperature interval, [15 ℃, 20 ℃ C. is a third temperature interval, [20 ℃, 25 ℃ C. is a fourth temperature interval, [25 ℃, 30 ℃ C. is a fifth temperature interval; alternatively, one temperature interval for every 3 ℃ temperature span, or one temperature interval for every 2 ℃ temperature span, etc. The preset temperature interval in this embodiment is only meant by an exemplary illustration of the temperature interval, and the preset temperature interval is not specifically limited, and a person skilled in the art can determine an appropriate first preset temperature interval according to actual conditions.
If the first detected temperature is 18 deg.C, the first detected temperature 18 deg.C is in a first temperature interval of [15 deg.C, 20 deg.C ].
S203, in one or more first temperature intervals, determining a specific temperature interval containing more than two first detected temperatures.
The first temperature zone may include one first detected temperature, i.e., only one among the plurality of first detected temperatures belongs to the first temperature zone; alternatively, the first temperature interval may include two first detected temperatures, that is, of the plurality of first detected temperatures, two first detected temperatures belong to the first temperature interval; alternatively, the first temperature section may include three first detected temperatures, that is, among the plurality of first detected temperatures, three first detected temperatures belong to the first temperature section. In this case, a first temperature section including two first detected temperatures and a first temperature section including three first detected temperatures are determined as the specific temperature section.
Of course, the number of the first detected temperatures included in the first temperature interval recited herein is merely an exemplary illustration, and is not limited to the embodiment, and those skilled in the art can determine the first temperature interval meeting the requirement as the specific temperature interval according to the actual situation. For example, the number of the second temperature sensors is increased, in this case, the first temperature interval may further include more than four first detected temperatures, and the range also belongs to the coverage of the present embodiment.
S204, under the condition that the number of the specific temperature intervals is more than two, determining the alternative detection temperature of the first temperature sensor according to the first detection temperature in the specific temperature intervals.
The number of specific temperature intervals may be two, three, four or more. In the embodiments of the present disclosure, the number of the specific temperature intervals is two, and an exemplary description is given.
In some practical applications, in the case that the number of the specific temperature intervals is one, the temperature span of each temperature interval in the first preset temperature interval is reduced, and the process of determining the first temperature interval in which each first detected temperature is located in the first preset temperature interval is executed again. For example, the initial division manner of the temperature interval in the first preset temperature interval is as follows: one temperature interval at [5 ℃, 10 ℃), a second temperature interval at [10 ℃, 15 ℃), a third temperature interval at [15 ℃, 20 ℃), a fourth temperature interval at [20 ℃, 25 ℃, and a fifth temperature interval at [25 ℃, 30 ℃). In this case, if the number of the obtained specific temperature intervals is one, the span of each temperature interval may be reduced from 5 ℃ to 4 ℃, for example, the first preset temperature interval after reducing the temperature span of each temperature interval includes: [5 ℃, 9 ℃), [9 ℃, 13 ℃), [13 ℃, 17 ℃), [17 ℃, 21 ℃), [21 ℃, 25 ℃), and [25 ℃, 29 ℃). If the number of the specific temperature intervals obtained at this time is two, the subsequent steps are executed, and if the number of the specific temperature intervals obtained at this time is still one, the temperature span of each temperature interval in the first preset temperature interval can be continuously reduced until the number of the obtained specific temperature intervals is two.
Optionally, determining an alternative detected temperature of the first temperature sensor from the first detected temperature in the particular temperature interval comprises: and obtaining a first average value of the first detection temperature in the specific temperature interval, and determining the alternative detection temperature according to the first average value.
Therefore, the substitute detection temperature can be determined, and the subsequent process of determining the indoor temperature is carried out.
The determining the alternative detection temperature according to the first average value may include: the first average is determined as the surrogate detection temperature.
Alternatively, determining the alternative detection temperature from the first average value may include: and obtaining a first product or a first sum of the first average value and a first preset coefficient, and determining the first product or the first sum as the substitute detection temperature.
For example, in the heating process of the air conditioner, if the indoor temperature is lower than the set temperature of the air conditioner, the first preset coefficient may be smaller than 1, a first product of the first average value and the first preset coefficient is obtained, and the first product is determined as the substitute detection temperature; alternatively, the first predetermined coefficient may be smaller than zero, a first sum of the first average value and the first predetermined coefficient is obtained, and the first sum is determined as the substitute detection temperature. Therefore, the heating effect of the air conditioner can be improved, and the time for the indoor temperature to reach the set temperature is reduced.
In the refrigeration process of the air conditioner, if the indoor temperature is higher than the set temperature of the air conditioner, the first preset coefficient can be larger than 1, a first product of the first average value and the first preset coefficient is obtained, and the first product is determined as the substitute detection temperature; alternatively, the first predetermined coefficient may be greater than zero, a first sum of the first average value and the first predetermined coefficient is obtained, and the first sum is determined as the substitute detection temperature. Therefore, the refrigerating effect of the air conditioner can be improved, and the time for the indoor temperature to reach the set temperature is reduced.
In some implementations, the first average is a first weighted average, and obtaining the first average of the first detected temperature in the specific temperature interval may include: acquiring the detection temperature of each normally working temperature sensor in the temperature sensor array; determining the number of detected temperatures of the normally operating temperature sensors in a specific temperature interval among the detected temperatures of the plurality of normally operating temperature sensors; determining the weight of each specific temperature interval according to the number of the detected temperatures of the temperature sensors which normally work in the specific temperature interval; determining the weight of each first detected temperature according to the weight of the specific temperature interval in which the first detected temperature is located; a first weighted average of the first detected temperatures in the specific temperature interval is obtained according to the weight of each first detected temperature.
The indoor temperature sensor array detects the temperature in one plane, and the indoor temperature is the temperature in a three-dimensional space. The temperature detected by the sensor array is substantially the temperature presented by the cross section of the plane where the sensor array is located after the indoor temperature is distributed according to the distribution rule of the temperature in the space. In the case of cooling with an air conditioner, the distribution law in the indoor space can be summarized as: the farther from the air conditioner, the higher its temperature; the further away from the air conditioner, the greater the distance between the two isotherms.
The greater the number of detected temperatures of the temperature sensors in a specific temperature interval, the more the temperature of the space in the indoor space is in the specific temperature interval. In the embodiment of the present disclosure, the greater the weight of the specific temperature section is, the greater the volume of the indoor space indicating that the temperature is in the specific temperature section is, and the smaller the weight of the specific temperature section is, the smaller the volume of the indoor space indicating that the temperature is in the specific temperature zone is. In this case, the larger the weight of the specific temperature section is, the more representative the temperature of the specific temperature section is with respect to the indoor space temperature is, and the smaller the weight of the specific temperature section is, the less representative the temperature of the specific temperature section is with respect to the indoor space temperature is.
The weight of the specific temperature zone in which the first detected temperature is located may be determined as the weight of the first detected temperature. For example, if the first detected temperature is 18 ℃ and belongs to the first temperature zone [15 ℃, 20 ℃), the weight of the first temperature zone [15 ℃, 20 ℃) may be determined as the weight of the first detected temperature of 18 ℃.
In the process of determining the weight of the first detected temperature, the weight of each first detected temperature can be determined, and then a first weighted average of the first detected temperatures in the specific temperature zone is obtained; alternatively, the weight of the first detected temperature in the specific temperature section may be determined, and then the first weighted average of the first detected temperature in the specific temperature zone may be obtained.
And obtaining products of each first detected temperature in the specific temperature interval and the corresponding first detected temperature, then obtaining the sum of all the products, dividing the sum of all the products by the sum of the weights of all the first detected temperatures in the specific temperature interval, and finally obtaining a first weighted average value.
By adopting the technical scheme, more accurate alternative detection temperature can be obtained.
And S205, determining the indoor temperature according to the alternative detection temperature and the detection temperature of each temperature sensor which normally works in the temperature sensor array.
For example, a second average value of the substitute detected temperature and the detected temperature of the temperature sensor that is operating normally is obtained, and the second average value is determined as the indoor temperature.
The air conditioner comprises a specific temperature interval, a plurality of first temperature sensors and a plurality of second temperature sensors, wherein the specific temperature interval comprises more than two first detection temperatures, the second temperature sensors corresponding to the more than two first detection temperatures are positioned on the same isotherm, and under the condition that the number of the specific temperature intervals is more than two, the areas where the first temperature sensors and the plurality of second temperature sensors are positioned can be represented, two isotherms are spanned, the first temperature sensors are usually positioned between the two isotherms, and the first alternative detection temperature is determined by the first detection temperatures of the second temperature sensors on the isotherms, so that errors caused by uneven distribution of the isotherms can be reduced, the accuracy of the alternative detection temperature is improved, the indoor temperature can be more accurately obtained, the air conditioner is temporarily controlled to better refrigerate or heat, and physical examination of a user is improved.
FIG. 3 is a partial schematic view of an array of temperature sensors provided by an embodiment of the present disclosure to illustrate the positional relationship of the first and second temperature sensors and the effect of the isotherm on the alternative sensed temperatures.
First, the positional relationship between the first temperature sensor and the second temperature sensor will be exemplarily described, with reference to fig. 3: if the temperature sensor TE5 is the first temperature sensor, the distances between the temperature sensors TE2, TE4, TE6 and TE8 and the first temperature sensor TE5 are first distances; the distance between the temperature sensors TE1, TE3, TE7 and TE9 and the first temperature sensor TE5 is a second distance, and the first distance is smaller than the second distance. In this application scenario, the temperature sensors TE2, TE4, TE6, and TE8 may be used as the second temperature sensors, or the temperature sensors TE1, TE2, TE3, TE4, TE6, TE7, TE8, and TE9 may be used as the second temperature sensors.
In the case where the temperature sensors TE1, TE4, and TE7 are edges of the temperature sensor array, if the temperature sensor TE4 is a first temperature sensor, the distances of the temperature sensors TE1, TE5, and TE7 from the first temperature sensor TE4 are a first distance, the distances of the temperature sensors TE2 and TE8 from the first temperature sensor are a second distance, and the first distance is smaller than the second distance. In this application scenario, the temperature sensors TE1, TE5 and TE7 may be used as the second temperature sensor, or the temperature sensors TE1, TE2, TE5, TE8 and TE7 may be used as the second temperature sensor.
Further exemplary illustrates the effect of the isotherm on the alternative sensed temperature, as shown in conjunction with FIG. 3: the temperature sensor TE5 is a first temperature sensor, and TE1, TE2, TE3, TE4, TE6, TE7, TE8 and TE9 are second temperature sensors. The curve A is an isotherm, and the dotted lines a1 and a2 are temperature intervals corresponding to the isotherm A; the curve B is another isotherm, and the dotted lines B1 and B2 are specific temperature intervals corresponding to the isotherm B.
In this case, if the temperature of the second temperature sensor TE1 is used in the process of determining the alternative detection temperature, the alternative detection temperature will be caused to be higher if the first detection temperature of the second temperature sensor TE1 is the highest, and will be caused to be lower if the first detection temperature of the second temperature sensor TE1 is the lowest. Correspondingly, in the process of determining the alternative detection temperature by using the first detection temperatures of the second temperature sensors TE2, TE3 and TE4 in one specific temperature interval and the second temperature sensors TE7, TE8 and TE9 in another specific temperature interval, the influence of the second temperature sensors TE1 and TE6 outside the isotherms a and B can be reduced (according to the present embodiment, the influence of the first detection temperature of the second temperature sensor TE6 on the alternative detection temperature is not large, and the first detection temperature of the second temperature sensor TE1 most easily causes the deviation of the alternative detection temperature), thereby more accurately determining the alternative detection temperature.
In the foregoing embodiment, a scheme is provided for determining the indoor temperature based on the second average value of the detected temperatures (including the alternative detected temperature and the detected temperature of the normally operating temperature sensor) of the respective temperature sensors (including the failed temperature sensor and the normally operating temperature sensor), and further, in order to determine a more accurate indoor temperature, another scheme may be employed for determining the indoor temperature.
Fig. 4 is a schematic diagram of a process for determining an indoor temperature according to an embodiment of the disclosure. As shown in fig. 4, determining the indoor temperature based on the alternative detected temperature and the detected temperature of each of the normally operating temperature sensors in the temperature sensor array includes:
s401, in a second preset temperature interval, determining a second temperature interval in which the detected temperature and the detected temperature of the temperature sensor which normally works are replaced.
The second preset temperature interval may be the same as the first preset temperature interval, and when the first preset temperature interval changes, the second preset temperature interval adaptively changes; or, the second preset temperature interval may also be independent of the first preset temperature interval and belong to a constant preset temperature interval, and the second preset temperature interval remains unchanged when the first preset temperature interval changes.
S402, determining the weight of each second temperature interval according to the total number of the substitute detection temperatures and the detection temperatures of the temperature sensors which normally work in each second temperature interval.
S403, determining the weight of the alternative detection temperature and the weight of the detection temperature of the normally working temperature sensor according to the weight of the second temperature interval in which the alternative detection temperature and the detection temperature of the normally working temperature sensor are located.
The weight of the second temperature interval in which the substitute detected temperature is located may be determined as the weight of the substitute detected temperature; the weight of the second temperature zone in which the detected temperature of the temperature sensor that normally operates is located may be determined as the weight of the detected temperature of the temperature sensor that normally operates.
S404, determining a second weighted average value of the alternative detection temperature and the detection temperature of the normal working temperature sensor according to the weights of the alternative detection temperature and the detection temperature of the normal working temperature sensor.
And S405, determining the indoor temperature according to the second weighted average value.
Wherein determining the indoor temperature according to the second weighted average may include: and determining the second weighted average value as the indoor temperature.
Or obtaining a second product or a second sum of the second weighted average and a second preset coefficient, and determining the second product or the second sum as the indoor temperature.
For example, in the heating process of the air conditioner, if the indoor temperature is lower than the set temperature of the air conditioner, the second preset coefficient may be smaller than 1, a second product of the second weighted average and the second preset coefficient is obtained, and the second product is determined as the substitute detection temperature; alternatively, the second preset coefficient may be smaller than zero, a second sum of the second weighted average and the second preset coefficient is obtained, and the second sum is determined as the substitute detection temperature. Therefore, the heating effect of the air conditioner can be improved, and the time for the indoor temperature to reach the set temperature is reduced.
In the refrigeration process of the air conditioner, if the indoor temperature is higher than the set temperature of the air conditioner, the second preset coefficient can be larger than 1, a second product of the second weighted average value and the second preset coefficient is obtained, and the second product is determined as the substitute detection temperature; alternatively, the second preset coefficient may be greater than zero, a second sum of the second weighted average and the second preset coefficient is obtained, and the second sum is determined as the substitute detection temperature. Therefore, the refrigerating effect of the air conditioner can be improved, and the time for the indoor temperature to reach the set temperature is reduced.
The substitute detected temperature and the detected temperature of the temperature sensor which normally operates with larger weight have more representative meaning to the indoor temperature, and the second weighted average value of the substitute detected temperature and the detected temperature of the temperature sensor which normally operates is obtained with such weight, and further the indoor temperature is determined according to the second weighted average value, and more accurate indoor temperature can be determined.
In some embodiments, an apparatus for detecting an indoor temperature includes a processor and a memory storing program instructions, the processor being configured to, when executing the program instructions, perform the method for detecting an indoor temperature provided by the foregoing embodiments.
