Description
Technical Field
The present application relates to the field of intelligent air-conditioning technology, and for example, to a method and an apparatus for detecting indoor temperature, and an intelligent air-conditioner.
Background
At present, an air conditioner detects an indoor temperature through a temperature sensor, and performs heating or cooling according to the indoor temperature and a set temperature. As the air conditioner ages, the temperature sensor may fail, resulting in a detected temperature that is not accurate enough or even unable to detect the temperature. In the prior art, a temperature range is usually set, if the temperature detected by the temperature sensor exceeds the temperature range, it is determined that the temperature sensor fails, in the process, the temperature range is the temperature "which the temperature sensor should" detect, and if the temperature sensor fails, a temperature can be selected from the temperature range to replace the temperature currently detected by the temperature sensor, so that the air conditioner can temporarily cool or heat, and a user has a better use experience.
With the development of air conditioner intellectualization, the indoor temperature can be detected through a plurality of temperature sensors, and then the air conditioner carries out refrigeration or heating according to the indoor temperature. In a scene that the indoor temperature is detected by a plurality of temperature sensors, a reference temperature is determined by a plurality of indoor temperatures detected by the plurality of temperature sensors, wherein the reference temperature is the temperature which the temperature sensor should detect, if the temperature detected by one temperature sensor is too different from the reference temperature, the temperature sensor is determined to be in fault, and further, the reference temperature can be temporarily substituted for the temperature detected by the fault temperature sensor to continue to cool or heat the air conditioner.
In a scenario where the indoor temperature is detected by the plurality of temperature sensors, the reference temperature is determined by the indoor temperatures detected by the plurality of temperature sensors, and is applicable to a scenario of one temperature sensor; if both temperature sensors fail, the temperature detected by the second failed temperature sensor is used to calculate a reference temperature instead of the temperature detected by the first failed temperature sensor, and likewise, the temperature detected by the first failed temperature sensor is used to calculate a reference temperature instead of the temperature detected by the second failed temperature sensor; alternatively, a reference temperature is calculated by the normally operating temperature sensors, and the reference temperature is used in place of the temperature detected by the first malfunctioning temperature sensor and the temperature detected by the second malfunctioning temperature sensor.
In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:
under the condition that the two temperature sensors have faults, the reference temperatures obtained through the two modes are not accurate enough, and the temperatures detected by the temperature sensors with the faults cannot be accurately replaced, so that the air conditioner under temporary control cannot be well cooled or heated, and the use experience of a user is reduced.

For example, if one temperature (the first substitute detection temperature, the second substitute detection temperature, or the detection temperature of the normally operating temperature sensor) is 18 ℃, and belongs to the temperature partition [15 ℃ and 20 ℃), the weight of the temperature partition [15 ℃ and 20 ℃) is the weight of the one temperature (the first substitute detection temperature, the second substitute detection temperature, or the detection temperature of the normally operating temperature sensor).

Alternatively, determining the indoor temperature from the weighted average may include: and obtaining a third product or a third sum of the weighted average value and a third preset coefficient, and determining the third product or the third 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 third preset coefficient may be smaller than 1, a third product of the weighted average value and the third preset coefficient is obtained, and the third product is determined as the second substitute detection temperature; or the third preset coefficient can be smaller than zero, a third sum of the weighted average value and the third preset coefficient is obtained, and the third sum is determined to be the second alternative detection temperature, so that 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 third preset coefficient can be larger than 1, a third product of the weighted average value and the third preset coefficient is obtained, and the third product is determined to be a second alternative detection temperature; or the third preset coefficient can be larger than zero, a third sum of the weighted average value and the third preset coefficient is obtained, and the third sum is determined to be the second alternative detection temperature, so that the refrigeration effect of the air conditioner can be improved, and the time for the indoor temperature to reach the set temperature is reduced.
The higher the weight of the first substitute detection temperature, the second substitute detection temperature or the detection temperature of the normally operating temperature sensor, the better representativeness to the indoor temperature is obtained, and the weighted average of the first substitute detection temperature, the second substitute detection temperature and the detection temperature of the normally operating temperature sensor is obtained by the weight, so that the indoor temperature can be more represented. By adopting the technical scheme for determining the indoor temperature, more accurate indoor temperature can be determined.
