Description
Technical Field
The invention relates to the technical field of intelligent home, in particular to an intelligent control method and device of an air conditioner and the air conditioner.
Background
There are two main types of air conditioners on the market: fixed frequency air conditioners and variable frequency air conditioners. The fixed-frequency air conditioner can only advance to the target temperature according to the set steps; the inverter air conditioner changes the working frequency of the compressor according to the variation trend of the ambient temperature, for example, during refrigeration, when the ambient temperature is greatly different from the target temperature, the inverter air conditioner runs at full load to increase the refrigerating capacity, and when the ambient temperature approaches the target temperature, the inverter air conditioner reduces the refrigerating capacity, so that the cooling speed is high. However, the demand for the rate of temperature change varies from population to population. For example, for a variable frequency air conditioner, when the target temperature is 25 degrees and the current temperature is 35 degrees, the variable frequency air conditioner may operate for 2 minutes and a half minutes to reduce the temperature to 26 degrees, namely, a temperature change rate of more than 3 degrees per minute, which is hard to bear for the elderly and is easy to cause health problems, and is comfortable for young and old people, so that the ambient temperature can reach an appropriate value as soon as possible.

Referring to fig. 1, as shown in fig. 1, the intelligent control method of an air conditioner according to the embodiment of the present invention includes steps S101 to S108, which are described in detail below.
Step S101: temperature data is acquired over a period of time, the temperature data including a current temperature.
In one embodiment, the acquired temperature data is temperature data at the user in order to more accurately reflect the actual experience of the user. The temperature data at the user location may be analyzed using infrared thermography techniques, or may be acquired by separate temperature sensing devices placed around the user.
Step S102: comparing the current temperature with a preset target temperature, judging whether the current temperature is greater than the target temperature by a first threshold, if so, executing step S103, otherwise, executing step S105.
Step S103: and judging the temperature change direction according to the acquired temperature data, and calculating the temperature change rate, wherein the temperature change direction comprises temperature increase and temperature decrease. Assume that temperature data is acquired over a time period of time t, with a starting temperature a and a final temperature b. When a is larger than b, the temperature change direction is temperature reduction, and the temperature change rate is (a-b)/t; when a is smaller than b, the temperature change direction is temperature increase, and the temperature change rate is (b-a)/t.
Step S104: and comparing the temperature change rate with the temperature change rate set by the user, and controlling the air conditioner to make adaptive adjustment by combining the temperature change direction according to the comparison result, so that the temperature change rate approaches to the temperature change rate set by the user, and the temperature approaches to the target temperature.
In one embodiment, referring to fig. 1, as shown in fig. 1, step S104 includes steps S114 to S144, and step S114 is executed when the temperature is increased, and step S124 is executed when the temperature is decreased, which will be described in detail below.
Step S114: the air conditioner is controlled to reduce the air outlet temperature and increase the air volume. At this time, the temperature is not in a proper range near the target temperature, but the temperature is in a rising trend, so that the air conditioner is controlled to reduce the outlet air temperature and increase the air volume to enable the temperature to approach the target temperature. It should be noted that, at this time, the setting of the outlet air temperature should also take into account the temperature change rate set by the user, for example, the target temperature is 25 degrees, the current temperature is 26 degrees, the current air conditioner outlet air temperature is 25 degrees, and the temperature change rate set by the user is 1 degree per minute, if the air conditioner power is large, the outlet air temperature is preferably reduced to 24 degrees, and if the air conditioner power is small, the outlet air temperature is reduced to 23 degrees, so that the temperature change rate can approach the temperature change rate set by the user. The above description is only one example of setting of the air conditioner outlet air temperature, and is not used to limit the value of the air conditioner outlet air temperature, and in practical applications, the specific outlet air temperature should be determined by combining the power of the air conditioner, so that the temperature change rate can approach the temperature change rate set by the user.
Step S124: and judging whether the temperature change rate is greater than the set temperature change rate, if so, executing step S134, and otherwise, executing step S144.
Step S134: the air conditioner is controlled to keep or improve the outlet air temperature, and correspondingly keep or reduce the air volume, so that the temperature change rate is reduced.
Step S144: the air conditioner is controlled to reduce the air outlet temperature and increase the air volume. At the moment, the temperature change rate is smaller than the set temperature change rate, the air outlet temperature is reduced, the air volume is increased, the temperature can approach the target temperature, and the temperature change rate is increased or unchanged.
Next, steps S124 to S144 will be described with a specific example, and it is assumed that the temperature change direction is always the temperature decrease in this example.
Assuming that the temperature change rate set by the user is 1 degree per minute, the current temperature is 35 degrees, and the air conditioner outlet air temperature is 32 degrees (3 degrees lower than the current temperature 35 degrees), if the temperature is reduced from 35 degrees to 34 degrees after 1 minute, namely the temperature change rate is not greater than 1 degree per minute, the air conditioner outlet air temperature is reduced to 30 degrees (4 degrees lower than the current ambient temperature 34 degrees), and the air volume is increased, if the temperature is reduced from 34 degrees to 33 degrees in less than 1 minute, namely the temperature change rate is greater than 1 degree per minute, the air conditioner air volume and the outlet air temperature are kept unchanged at 30 degrees (3 degrees lower than the current ambient temperature 33 degrees), and so on, so that the temperature change rate approaches the temperature change rate set by the user, and the temperature approaches the target temperature. The above description is only one example of setting of the air conditioner outlet air temperature, and is not used to limit the value of the air conditioner outlet air temperature, and in practical applications, the specific outlet air temperature should be determined by combining the power of the air conditioner, so that the temperature change rate can approach the temperature change rate set by the user.
In another embodiment, referring to fig. 2, as shown in fig. 2, step S104 includes steps S114 to S154, which are described in detail below.
Step S114: and receiving user position information, wherein the position information is used for indicating the position of the user relative to the air conditioner, such as 2 meters right in front, 3 meters right below and the like. When the temperature increases, step S124 is performed, and when the temperature decreases, step S134 is performed.
Step S124: controlling the air conditioner to reduce the air outlet temperature and increase the air volume; and controlling an air deflector of the air conditioner to rotate, so that wind blows to a target position represented by the user position information. At this time, the temperature is not in a proper range near the target temperature, but the temperature is in a rising trend, so that the air conditioner is controlled to reduce the outlet air temperature, increase the air volume and blow the air to the user, so that the temperature at the user is close to the target temperature. It should be noted that, at this time, the setting of the outlet air temperature should also take into account the temperature change rate set by the user, for example, the target temperature is 25 degrees, the current temperature is 26 degrees, the current air conditioner outlet air temperature is 25 degrees, and the temperature change rate set by the user is 1 degree per minute, if the air conditioner power is large, the outlet air temperature is preferably reduced to 24 degrees, and if the air conditioner power is small, the outlet air temperature is reduced to 23 degrees, so that the temperature change rate can approach the temperature change rate set by the user. The above description is only one example of setting of the air conditioner outlet air temperature, and is not used to limit the value of the air conditioner outlet air temperature, and in practical applications, the specific outlet air temperature should be determined by combining the power of the air conditioner, so that the temperature change rate can approach the temperature change rate set by the user.
Step S134: and judging whether the temperature change rate is larger than the set temperature change rate, if so, executing a step S134, and otherwise, executing a step S144.
Step S144: controlling the air conditioner to keep or improve the air outlet temperature and correspondingly keep or reduce the air volume; the air deflector of the air conditioner is controlled to rotate, so that wind blows to other positions, and the temperature change rate of a user is reduced.
Step S154: controlling the air conditioner to reduce the air outlet temperature and increase the air volume; and controlling an air deflector of the air conditioner to rotate, so that wind blows to a target position represented by the user position information. At the moment, the temperature change rate is smaller than the set temperature change rate, the air outlet temperature is reduced, the air volume is increased, the air is blown to the user, the temperature of the user can approach the target temperature, and the temperature change rate is increased or unchanged.
Next, steps S134 to S154 will be described with a specific example, and it is assumed that the temperature change direction is always the temperature decrease in this example.
Assuming that the temperature change rate set by the user is 1 degree per minute, the current temperature is 35 degrees, the air conditioner outlet air temperature is 32 degrees (3 degrees lower than the current temperature 35 degrees), if the temperature is reduced from 35 degrees to 34 degrees after 1 minute, i.e., the temperature change rate is not greater than 1 degree per minute, the air conditioner outlet air temperature is reduced to 30 degrees (4 degrees lower than the current environment temperature 34 degrees), the air quantity is increased and the air is blown to the target position represented by the user position information, if the temperature is lower than 1 minute, the temperature is reduced from 34 degrees to 33 degrees, namely the temperature change rate is more than 1 degree per minute, the air volume of the air conditioner and the outlet air temperature are kept unchanged at 30 degrees (3 degrees lower than the current environment temperature of 33 degrees), the air is blown to other places, and the like, so that the temperature change rate at the user approaches the temperature change rate set by the user and the temperature approaches the target temperature. The above description is only one example of setting of the air conditioner outlet air temperature, and is not used to limit the value of the air conditioner outlet air temperature, and in practical applications, the specific outlet air temperature should be determined by combining the power of the air conditioner, so that the temperature change rate can approach the temperature change rate set by the user.
The following description continues with step S105 to step S108.
Step S105: and judging whether the current temperature is smaller than the target temperature by a third threshold value or not, or judging whether the current temperature is smaller than a lower limit value preset by a user or not. If yes, step S106 is executed, otherwise, step S107 is executed.
Step S106: the air conditioner is turned off. At night or in rainy days, if the air conditioner has larger power and the room is smaller, even if the outlet air temperature of the air conditioner is adjusted to be higher, for example, 30 ℃, the room temperature may still be reduced, and the air conditioner is not suitable to continue to work. In one embodiment, this is indicated by setting a third threshold, when the current temperature is less than the target temperature by the third threshold, indicating that the current temperature has been too low, and then turning off the air conditioner to prevent the temperature from continuing to decrease. In another embodiment, the user can set a lower limit value according to the user experience, and when the current temperature is lower than the lower limit value preset by the user, the air conditioner is turned off to prevent the temperature from continuously decreasing.
Step S107: and judging whether the current temperature is smaller than the target temperature by a second threshold value, wherein the third threshold value is larger than the second threshold value. If so, step S108 is executed, otherwise, it indicates that the current temperature is smaller than the target temperature by the first threshold and larger than the target temperature by the second threshold, and is within a suitable range around the target temperature, so that the operating state of the air conditioner does not need to be adjusted.
Step S108: the air conditioner is controlled to raise the temperature of the outlet air and reduce the air volume so as to raise the temperature and approach to the target temperature. It should be noted that, at this time, the setting of the outlet air temperature should also take into account the temperature change rate set by the user, for example, the target temperature is 25 degrees, the current temperature is 24 degrees, the current air conditioner outlet air temperature is 25 degrees, and the temperature change rate set by the user is 1 degree per minute, if the air conditioner power is large, the outlet air temperature is preferably increased to 26 degrees, and if the air conditioner power is small, the outlet air temperature is increased to 27 degrees, so that the temperature change rate can approach the temperature change rate set by the user. The above description is only one example of setting of the air conditioner outlet air temperature, and is not used to limit the value of the air conditioner outlet air temperature, and in practical applications, the specific outlet air temperature should be determined by combining the power of the air conditioner, so that the temperature change rate can approach the temperature change rate set by the user.
Referring to fig. 3, as shown in fig. 3, the intelligent control device for an air conditioner according to an embodiment of the present invention includes a temperature sensor 1, a first control module 2, a third control module 3, and a second control module 4, which are described in detail below.
The temperature sensor 1 is used to acquire temperature data over a period of time, which includes the current temperature.
The first control module 2 is configured to control the air conditioner when the current temperature is greater than a preset target temperature by a first threshold, so that the temperature change rate approaches a temperature change rate set by a user, and the temperature approaches the target temperature. The first control module 2 includes a temperature change detection unit 21, a temperature control unit 22, and a wind control unit 23, which are described in detail below.
The temperature change detection unit 21 is configured to determine a temperature change direction including a temperature increase and a temperature decrease from the temperature data acquired by the temperature sensor 1, and calculate a temperature change rate. Assume that temperature data is acquired over a time period of time t, with a starting temperature a and a final temperature b. When a is larger than b, the temperature change direction is temperature reduction, and the temperature change rate is (a-b)/t; when a is smaller than b, the temperature change direction is temperature increase, and the temperature change rate is (b-a)/t.
The temperature control unit 22 is configured to, when the temperature change direction is temperature decrease, control the air conditioner to maintain or increase the outlet air temperature if the temperature change rate is greater than the temperature change rate set by the user, and control the air conditioner to decrease the outlet air temperature if the temperature change rate is less than the temperature change rate set by the user; and when the temperature change direction is temperature rise, controlling the air conditioner to reduce the outlet air temperature. It should be noted that, when the temperature change direction is temperature increase, the setting of the outlet air temperature should also take into account the temperature change rate set by the user, for example, the target temperature is 25 degrees, the current temperature is 26 degrees, the current air-conditioning outlet air temperature is 25 degrees, the temperature change rate set by the user is 1 degree per minute, if the air-conditioning power is large, the outlet air temperature is preferably reduced to 24 degrees, and if the air-conditioning power is small, the outlet air temperature is reduced to 23 degrees, so that the temperature change rate can approach the temperature change rate set by the user. The above description is only one example of setting of the air conditioner outlet air temperature, and is not used to limit the value of the air conditioner outlet air temperature, and in practical applications, the specific outlet air temperature should be determined by combining the power of the air conditioner, so that the temperature change rate can approach the temperature change rate set by the user.
The air volume control unit 23 is used for controlling the air conditioner to maintain or reduce the air volume if the temperature change rate is greater than the temperature change rate set by the user when the temperature change direction is temperature reduction, and controlling the air conditioner to increase the air volume if the temperature change rate is less than the temperature change rate set by the user; and when the temperature change direction is temperature rise, controlling the air conditioner to increase the air volume.
The first control module 2 will be described below with a specific example, assuming that the temperature change direction is always a temperature decrease in this example.
Assuming that the temperature change rate set by the user is 1 degree per minute, the current temperature is 35 degrees, and the air-conditioning outlet air temperature is 32 degrees (3 degrees lower than the current temperature 35 degrees), if the temperature is reduced from 35 degrees to 34 degrees after 1 minute, that is, the temperature change rate is not greater than 1 degree per minute, the first control module 2 controls the air conditioner to reduce the air-conditioning outlet air temperature to 30 degrees (4 degrees lower than the current ambient temperature 34 degrees) and increase the air volume, if the temperature is reduced from 34 degrees to 33 degrees in less than 1 minute, that is, the temperature change rate is greater than 1 degree per minute, the first control module 2 controls the air conditioner to keep the air volume and the air-outlet air temperature unchanged by 30 degrees (3 degrees lower than the current ambient temperature 33 degrees), and so on, so that the temperature change rate approaches the temperature change rate set by the user, and the temperature approaches the target temperature. The above description is only one example of setting of the air conditioner outlet air temperature, and is not used to limit the value of the air conditioner outlet air temperature, and in practical applications, the specific outlet air temperature should be determined by combining the power of the air conditioner, so that the temperature change rate can approach the temperature change rate set by the user.
In one embodiment, referring to fig. 4, as shown in fig. 4, the first control module 2 further includes a position information receiving unit 24 and an air direction control unit 25. The following is a detailed description.
The location information receiving unit 24 is configured to receive location information of the user, and the location information is used to indicate a location of the user relative to the air conditioner, such as 2 meters directly in front, 3 meters directly below, and the like.
The wind direction control unit 25 is configured to, when the temperature change direction is temperature decrease, control the air deflector of the air conditioner to rotate if the temperature change rate is greater than the temperature change rate set by the user, so that wind blows to other locations, and control the air deflector of the air conditioner to rotate if the temperature change rate is less than the temperature change rate set by the user, so that wind blows to a target location represented by the user location information; and when the temperature change direction is temperature rise, controlling the air deflector of the air conditioner to rotate, so that the wind blows to the target position represented by the user position information.
The first control module 2 of the present embodiment will be described below with a specific example, and it is assumed that the temperature change direction is always a temperature decrease in this example.
Assuming that the temperature change rate set by the user is 1 degree per minute, the current temperature is 35 degrees, and the air-conditioning outlet air temperature is 32 degrees (3 degrees lower than the current temperature 35 degrees), if the temperature is reduced from 35 degrees to 34 degrees after 1 minute, that is, the temperature change rate is not greater than 1 degree per minute, the first control module 2 controls the air conditioner to reduce the air-conditioning outlet air temperature to 30 degrees (4 degrees lower than the current ambient temperature 34 degrees), and increases the air volume and blows the air to the target position represented by the user position information, if the temperature is reduced from 34 degrees to 33 degrees in less than 1 minute, that is, the temperature change rate is greater than 1 degree per minute, the first control module 2 controls the air conditioner to keep the air volume and the air-outlet air temperature unchanged by 30 degrees (3 degrees lower than the current ambient temperature by 33 degrees), and blows the air to other positions, and so on, the temperature change rate at the user position approaches to the temperature change rate set by the user, and the temperature is brought close to the target temperature. The above description is only one example of setting of the air conditioner outlet air temperature, and is not used to limit the value of the air conditioner outlet air temperature, and in practical applications, the specific outlet air temperature should be determined by combining the power of the air conditioner, so that the temperature change rate can approach the temperature change rate set by the user.
The third control module 3 is used for turning off the air conditioner when the current temperature is smaller than the target temperature by a third threshold value or the current temperature is smaller than a lower limit value preset by a user. At night or in rainy days, if the air conditioner has larger power and the room is smaller, even if the outlet air temperature of the air conditioner is adjusted to be higher, for example, 30 ℃, the room temperature may still be reduced, and the air conditioner is not suitable to continue to work. In one embodiment, this is indicated by setting a third threshold, when the current temperature is less than the target temperature by the third threshold, indicating that the current temperature has been too low, and then turning off the air conditioner to prevent the temperature from continuing to decrease. In another embodiment, the user can set a lower limit value autonomously according to the user experience, and when the current temperature is lower than the lower limit value preset by the user, the air conditioner is turned off to prevent the temperature from continuously decreasing.
The second control module 4 is used for controlling the air conditioner to increase the air outlet temperature and reduce the air volume when the current temperature is smaller than the target temperature by a second threshold value, so that the temperature rises back to approach the target temperature. Wherein the third threshold is greater than the second threshold. It should be noted that, at this time, the setting of the outlet air temperature should also take into account the temperature change rate set by the user, for example, the target temperature is 25 degrees, the current temperature is 24 degrees, the current air conditioner outlet air temperature is 25 degrees, and the temperature change rate set by the user is 1 degree per minute, if the air conditioner power is large, the outlet air temperature is preferably increased to 26 degrees, and if the air conditioner power is small, the outlet air temperature is increased to 27 degrees, so that the temperature change rate can approach the temperature change rate set by the user. The above description is only one example of setting of the air conditioner outlet air temperature, and is not used to limit the value of the air conditioner outlet air temperature, and in practical applications, the specific outlet air temperature should be determined by combining the power of the air conditioner, so that the temperature change rate can approach the temperature change rate set by the user.
The intelligent control device of the air conditioner of the embodiment can be arranged on the air conditioner body and can also be arranged around a user. When the device is arranged around a user, the temperature sensor 1 acquires temperature data of the user, actual experience of the user can be reflected more accurately, and the device can send an instruction to the air conditioner in an infrared communication mode to control the air conditioner.
