The method for detecting indoor temperature may be performed by a temperature sensor array, may be performed by a smart air conditioner or a control terminal of a smart home system, may also be performed by a home cloud platform, and may also be performed by a smart air conditioner.

As shown in Figure 2, the methods for detecting the indoor temperature include:

S201. When detecting indoor temperature through a temperature sensor array installed indoors, if a first temperature sensor of the temperature sensor array fails, obtain first detected temperatures of a plurality of second temperature sensors adjacent to the first temperature sensor.

Wherein, the temperature sensor array includes a plurality of temperature sensors, and the plurality of temperature sensors are arranged vertically and horizontally.

If the first temperature sensor is at the non-edge of the temperature sensor array, then there are 8 temperature sensors adjacent to the first temperature sensor, wherein the distance between 4 temperature sensors and the first temperature sensor is the first distance, and the other 4 temperature sensors The distance between the sensor and the first temperature sensor is a second distance, and the first distance is smaller than the second distance. In this scenario, the first detected temperatures of eight second temperature sensors are obtained; or, the first detected temperatures of four second temperature sensors at a first distance from the first temperature sensors are obtained.

If the first temperature sensor is at the edge of the temperature sensor array and not at the corner, then there are 5 temperature sensors adjacent to the first temperature sensor, wherein the distance between 3 temperature sensors and the first temperature sensor is the first distance, and the other 2 The distance between each temperature sensor 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 five second temperature sensors are obtained; or, the first detected temperatures of the three second temperature sensors at a first distance from the first temperature sensors are obtained.

If the first temperature sensor is at the corner of the temperature sensor array, then there are 3 temperature sensors adjacent to the first temperature sensor, wherein the distance between 2 temperature sensors and the first temperature sensor is the first distance, and the other 1 temperature sensor The distance from 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 five second temperature sensors are obtained; or, the first detected temperatures of two second temperature sensors at a first distance from the first temperature sensor are obtained.

S202. Obtain the weight of the first detected temperature of each second temperature sensor.

Wherein, the weight of the first detected temperature is positively related to the aggregation degree of the first detected temperature among the detected temperatures of all temperature sensors.

All the temperature sensors here refer to all the temperature sensors in the temperature sensor array.

The degree of aggregation here can be expressed by the number of detected temperatures within a set range of the difference from the first detected temperature, or by the number of detected temperatures within a temperature range where the first detected temperature is located.

In the case of using the number of detected temperatures within a temperature range where the first detected temperature is located to represent the degree of aggregation, obtaining the weight of the first detected temperature of each second temperature sensor includes: obtaining the weight of each normal working temperature sensor in the temperature sensor array The detection temperature of the temperature sensor; determine the first temperature division where the detection temperature of each normal working temperature sensor is located in the first preset temperature division; obtain the quantity of the detection temperature of the normal working temperature sensor in each first temperature division ; Determine the weight of each first temperature zone according to the number of detected temperatures of the temperature sensor in normal operation; determine the weight of each first detected temperature according to the weight of the first temperature zone where each first detected temperature is located.

The normal working temperature sensor here includes the aforementioned second temperature sensor; the detected temperature of the normal working temperature sensor here includes the first detected temperature of the aforementioned second temperature sensor.

The first preset temperature zone is a pre-divided temperature zone. For example, [5°C, 10°C) is one temperature zone, [10°C, 15°C) is the second temperature zone, [15°C, 20°C) is the third temperature zone, and [20°C, 25°C) is the second temperature zone. Four temperature zones, [25°C, 30°C) is the fifth temperature zone; or, every temperature span of 3°C is a temperature zone, or every temperature span of 2°C is a temperature zone, etc. The preset temperature zone in this embodiment is only an example to illustrate the meaning of the temperature zone, and does not constitute a specific limitation on the preset temperature zone. Those skilled in the art can determine a suitable first preset temperature zone according to the actual situation.

If a normally working temperature sensor detects 18°C, the first temperature zone where the detected temperature of 18°C is located is [15°C, 20°C).

In a first temperature zone, the more the number of temperatures detected by the temperature sensors that work normally, the greater the weight of the first temperature zone. The corresponding relationship between the number of detected temperatures of the temperature sensors that work normally in the first temperature zone and the weight of the first temperature zone can be pre-stored in the database. When it is necessary to obtain the weight of a first temperature zone, the database can be queried The weight of the first temperature zone can be obtained by the number of detected temperatures of the temperature sensors working normally in the first temperature zone.

In addition, the number of detected temperatures of temperature sensors that work normally in one first temperature zone may also be used as the weight of the one first temperature zone. The indoor sensor array detects the temperature in a plane, and the indoor temperature is the temperature in a three-dimensional space. The more the number of detected temperatures that work normally in a first temperature zone, it means that there are more spaces in the indoor space in this one. In the first temperature zone, in the embodiment of the present disclosure, the weight of the first temperature zone can represent the amount of indoor space in the first temperature zone. The greater the weight of a first temperature zone, the greater the weight of the first temperature zone The more indoor space in the zone, the smaller the weight of a first temperature zone, and the less indoor space in the first temperature zone. The weight of the first detected temperature determined according to this can more accurately indicate how representative the first detected temperature is to the indoor temperature.

The weight of the first temperature zone where a first detected temperature is located is the weight of the first detected temperature. For example, the detection temperature of a normal working temperature sensor is 18°C, which belongs to the first temperature zone [15°C, 20°C), then the weight of the first detection temperature of 18°C is the first temperature zone [15°C, 20°C )the weight of.

S203. Obtain a first weighted average of multiple first detected temperatures.

After obtaining the weight of each first detection temperature, the product of each first detection temperature and its corresponding weight can be obtained, and then use the sum of multiple products to divide by the sum of the weights of all first detection temperatures, that is A first weighted average may be obtained.

Alternatively, obtaining the first weighted average of the multiple first detected temperatures may include: performing normalization processing on the weights of the multiple first detected temperatures; determining the weights of the multiple first detected temperatures according to the normalized weights First weighted average. That is, by calculating the product of each first detected temperature and its corresponding weight after normalization processing, and then obtaining the sum of all products, the first weighted average temperature value can be obtained. It can be seen that after the normalization processing, the first weighted average value of the multiple first detected temperatures and the first weighted sum of the multiple first detected temperatures belong to the same data. The first weighted sum of the first detected temperatures, and then determining the alternative detected temperature of the first temperature sensor according to the first weighted sum also belong to the coverage of the embodiments of the present disclosure.

Through the above solution, the first weighted average of the multiple first detected temperatures can be obtained.

S204. Determine an alternative detection temperature of the first temperature sensor according to the first weighted average value.

Optionally, determining the alternative detection temperature of the first temperature sensor according to the first weighted average includes: using the first weighted average as the alternative detection temperature of the first temperature sensor.

Alternatively, determining the alternative detection temperature of the first temperature sensor according to the first weighted average includes: obtaining the first product or the first sum of the first weighted average and the first preset coefficient, and determining the first product or the first sum and for the alternative 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 can be less than 1, and the first product of the first weighted average value and the first preset coefficient can be obtained to determine the first The product is the alternative detection temperature; or, the first preset coefficient can be less than zero, the first sum of the first weighted average and the first preset coefficient is obtained, and the first sum is determined to be the alternative detection temperature, which can improve the performance of the air conditioner Heating effect, reducing the time for the indoor temperature to reach the set temperature.

During the cooling 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 greater than 1, and the first product of the first weighted average value and the first preset coefficient is obtained, and the first product is determined as an alternative detection temperature; or, the first preset coefficient may be greater than zero, obtain the first sum of the first weighted average value and the first preset coefficient, and determine the first sum as an alternative detection temperature, which can improve the cooling effect of the air conditioner, Reduce the time for the room temperature to reach the set temperature.

S205. Determine the indoor temperature according to the detected temperature of the substitute detected temperature and the detected temperature of the normally working temperature sensor in the temperature sensor array.

For example, determining the indoor temperature according to the detection temperature of the alternative detection temperature and the temperature sensor normally operating in the temperature sensor array, including: obtaining the average value of the detection temperature of the alternative detection temperature and the temperature sensor normally operating in the temperature sensor array, and determining the average value is the room temperature.

In the aforementioned embodiments, the method for determining the indoor temperature is provided based on the average value of the detection temperature (including the detection temperature of the alternative detection temperature and the normal operation temperature sensor) of each temperature sensor (including the temperature sensor of failure and the temperature sensor of normal operation). solution, further, in order to determine a more accurate indoor temperature, another solution can also be used to determine the indoor temperature.

Fig. 3 is a schematic diagram of a process of determining an indoor temperature provided by an embodiment of the present disclosure. As shown in Figure 3, the indoor temperature is determined according to the detection temperature of the alternative detection temperature and the normal working temperature sensor in the temperature sensor array, including:

S301. In the second preset temperature zone, determine the second temperature zone where the detection temperature of the substitute detection temperature and the temperature sensor in normal operation are located.

The second preset temperature zone is a pre-divided temperature zone. For example, [5°C, 10°C) is one temperature zone, [10°C, 15°C) is the second temperature zone, [15°C, 20°C) is the third temperature zone, and [20°C, 25°C) is the second temperature zone. Four temperature zones, [25°C, 30°C) is the fifth temperature zone; or, every temperature span of 3°C is a temperature zone, or every temperature span of 2°C is a temperature zone, etc. The preset temperature zone in this embodiment is only an example to illustrate the meaning of the temperature zone, and does not constitute a specific limitation on the preset temperature zone. Those skilled in the art can determine a suitable second preset temperature zone according to the actual situation.

If a normal working temperature sensor detects 18°C, then the second temperature zone where the detection temperature 18°C is located is [15°C, 20°C); The second temperature zone is [15°C, 20°C).

S302. Obtain the total quantity of the detection temperature of the substitute detection temperature and the normal working temperature sensor in each second temperature zone.

S303. Determine the weight of each second temperature zone according to the total quantity of the substitute detection temperature and the detection temperature of the normal working temperature sensor in each second temperature zone.

In a second temperature zone, the more the total number of detected temperatures of the substitute detection temperature and the normal working temperature sensor is, the greater the weight of the second temperature zone is. The corresponding relationship between the total quantity of the detection temperature of the alternative detection temperature and the normal working temperature sensor in the second temperature division and the weight of the second temperature division can be pre-stored in the database. When it is necessary to obtain the weight of a second temperature division, The weight of the second temperature zone can be obtained by querying the database for the total quantity of the temperature detected instead of the detected temperature of the temperature sensor in normal operation.

In addition, the total number of the detected temperatures of the substitute detection temperature and the normal working temperature sensor in a second temperature division may also be used as the weight of the second temperature division.

The indoor sensor array detects the temperature in a plane, and the indoor temperature is the temperature in a three-dimensional space. The more the total number of alternative detection temperatures and normal working detection temperatures in a second temperature zone, it means that there are more in the indoor space. The space in the second temperature zone is in the second temperature zone. In the embodiment of the present disclosure, the weight of a second temperature zone can represent the number of indoor spaces in the first temperature zone. The greater the weight of a second temperature zone, the greater the weight of the second temperature zone. The more indoor spaces in the one second temperature zone, the smaller the weight of one second temperature zone, and the less the indoor space in the one second temperature zone. The weights of the alternative detection temperature and the weights of the detection temperature of the normal working temperature sensor determined accordingly can more accurately indicate the respective degrees of representation of the indoor temperature, thereby determining a more accurate indoor temperature.

S304. Determine the weights of the substitute detection temperature and the detection temperature of the normal operation temperature sensor according to the weights of the substitution detection temperature and the second temperature zone where the detection temperature of the normal operation temperature sensor is located.

The weight of the second temperature zone where the alternative detection temperature or the detection temperature of a normally operating temperature sensor is located is the weight of the alternative detection temperature or the detection temperature of the one normally operating temperature sensor. For example, if the alternative detection temperature or the detection temperature of a normal working temperature sensor is 18°C, which belongs to the second temperature zone [15°C, 20°C), then the weight of the substitute detection temperature of 18°C or the normal working temperature sensor The weight of the detection temperature 18°C is the weight of the second temperature division [15°C, 20°C).

S305. Determine a second weighted average value of the substitute detection temperature and the detection temperature of the normally operating temperature sensor according to the weights of the substitute detection temperature and the detection temperature of the normally operating temperature sensor.

After obtaining the weight of the detection temperature of the substitute detection temperature and the normal working temperature sensor, the product of the substitute detection temperature and its corresponding weight can be obtained, the detection temperature of the normal working temperature sensor and its corresponding weight product can be obtained, and multiple products can be obtained and then use the sum of multiple products to divide by the sum of the weights of the alternative detection temperature and the weights of the detection temperatures of all temperature sensors that work normally to obtain the second weighted average.

Or, according to the weight of the detection temperature of the temperature sensor of the replacement detection temperature and the normal operation, determining the second weighted average value of the detection temperature of the detection temperature of the temperature sensor of the replacement detection temperature and the normal operation may include: The weights of the detected temperatures of the sensors are normalized; according to the normalized weights, a second weighted average of the detected temperatures of the alternative detected temperatures and the temperature sensors in normal operation is determined. That is, calculate the product of the alternative detected temperature and its corresponding normalized weight, calculate the product of the detected temperature of each normal working temperature sensor and its corresponding normalized weight, and then obtain the sum of all products, that is, Get the second weighted average. It can be seen that after the normalization process, the second weighted average of the detection temperature of the replacement detection temperature and the normal working temperature sensor, and the second weighted sum of the detection temperature of the replacement detection temperature and the normal operation temperature sensor belong to the same Therefore, determining the second weighted sum of the alternative detection temperature and the detection temperature of the normal operating temperature sensor according to the weight after normalization processing, and then determining the alternative detection temperature of the first temperature sensor according to the second weighted sum, also belongs to this Coverage of the disclosed embodiments.

Through the above technical solution, the second weighted average value of the detection temperature of the replacement detection temperature and the temperature sensor in normal operation can be obtained.

S306. Determine the indoor temperature according to the second weighted average value.

Optionally, determining the indoor temperature according to the second weighted average includes: determining that the second weighted average is the indoor temperature.

Or, determining the indoor temperature according to the second weighted average may include: 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 less than 1, and the second product of the second weighted average value and the second preset coefficient is obtained to determine the second The product is the alternative detection temperature; or, the second preset coefficient can be less than zero, and the second sum of the second weighted average value and the second preset coefficient is obtained, and the second sum is determined to be the alternative detection temperature, which can improve the performance of the air conditioner. Heating effect, reducing the time for the indoor temperature to reach the set temperature.

In the cooling 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 greater than 1, obtain the second product of the second weighted average value and the second preset coefficient, and determine the second product as an alternative Detecting temperature; or, the second preset coefficient can be greater than zero, obtain the second sum of the second weighted average value and the second preset coefficient, and determine the second sum as an alternative detection temperature, which can improve the cooling effect of the air conditioner, Reduce the time for the room temperature to reach the set temperature.

The detected temperature of the normal working temperature sensor with higher weight, or the alternative detected temperature with higher weight, has a better representation of the indoor temperature, and the alternative detected temperature and the detected temperature of the normal working temperature sensor are obtained with such a weight The second weighted average of , which is more representative of the room temperature. By adopting the above technical solution for determining the indoor temperature, a more accurate indoor temperature can be determined.
