Further, in step S1, in the case that the air conditioner operates in the sleep mode, the controller can acquire a change situation of the outdoor temperature within a preset time period and a current change trend and a current change rate of the outdoor temperature. It should be noted that, the specific interval of the preset time period and the specific parameter type reflecting the change condition are not limited by the present invention, and the technical personnel can set the time period according to the actual use requirement.
In addition, it should be noted that the invention does not limit the specific time when the air conditioner enters the sleep mode, and the technicians can set the time according to the actual use requirements; preferably, the air conditioner can be in communication connection with the intelligent wearable device of the user, and the sleep condition of the user is detected through the intelligent wearable device of the user, so that the air conditioner is controlled to correspondingly enter a sleep mode; of course, the system can be controlled manually by a user, and can also enter automatically in a preset time period, and the like.
As a preferable collection manner, when the air conditioner is powered on, the micro control unit can collect the outdoor temperature in real time through the outdoor temperature sensor, and draw the collected outdoor temperature into an outdoor temperature change curve to be stored in the memory so as to be called when needed.
Of course, the above-mentioned collection mode is only a preferred collection mode, and technicians can also adjust themselves according to actual use requirements; for example, the outdoor temperature may be obtained not in real time but once at preset time intervals; in addition, all the data may be directly stored in the memory without plotting the collected data into a temperature change curve.
The outdoor temperature change curve can effectively reflect the change condition of the outdoor temperature, and the micro control unit can acquire the curve in the preset time period according to the use requirement so as to effectively acquire the change condition of the outdoor temperature in the preset time period.
Further, in step S2, the controller may determine a first correction coefficient according to a change condition of the outdoor temperature within a preset time period, and a current change trend and a current change rate of the outdoor temperature; it should be noted that, the present invention does not set any limitation on the specific determination manner, and a technician may set the determination manner according to actual use requirements, and the present invention is within the protection scope as long as the first correction coefficient is determined according to the change condition of the outdoor temperature within the preset time period, the current change trend of the outdoor temperature, and the current change rate; for example, the first correction coefficient may be obtained by determining different corresponding equations according to the change conditions of the outdoor temperature within a preset time period, and then substituting the current change trend and the current change rate of the outdoor temperature into the equations for calculation.
As a preferred determination manner, the preset time period may be selected to be twelve hours, so as to effectively ensure that the temperature change condition in the time period can be closest to the current temperature change condition. Meanwhile, the current season situation can be judged according to the maximum value and the minimum value of the outdoor temperature in the preset time period, namely, five different temperature intervals are determined according to the maximum value and the minimum value of the outdoor temperature in the preset time period, and each interval corresponds to five season situations of extremely cold, comfortable, hot and extremely hot; of course, the present invention does not limit the specific division manner of the temperature range, and the technicians can set the temperature range according to the actual use requirements.

Based on the determined seasonal situation, a first correction factor can be determined by combining the current variation trend and the current variation rate of the outdoor temperature. Specifically, the positive and negative of the first correction coefficient can be determined according to the current variation trend of the outdoor temperature: if the outdoor temperature is in an increasing trend, the first correction coefficient is a positive value; and if the outdoor temperature is in a decreasing trend, the first correction coefficient is a negative value. In addition, the magnitude of the first correction coefficient can be determined according to the seasonal conditions and the current change rate, for example, a coefficient is determined according to the seasonal conditions, and then the coefficient is multiplied by the current change rate to obtain the first correction coefficient, the coefficient determined under the extremely cold and extremely hot conditions is the largest, the coefficient determined under the cold and hot conditions is centered, and the coefficient determined under the comfortable condition is the smallest.

As a preferable collection manner, when the air conditioner is powered on, the micro control unit can collect the indoor temperature in real time through the indoor temperature sensor, and draw the collected indoor temperature into an indoor temperature change curve to be stored in the memory so as to be called when needed. Of course, the above-mentioned collection mode is only a preferred collection mode, and technicians can also adjust themselves according to actual use requirements; for example, the indoor temperature may be obtained not in real time but once at a preset time interval; in addition, all the data may be directly stored in the memory without plotting the collected data into a temperature change curve.
The indoor temperature change curve can effectively reflect the change situation of the indoor temperature, and the micro control unit can acquire the curve in the preset time period according to the use requirement so as to effectively acquire the change situation of the indoor temperature in the preset time period.
Further, in step S4, the controller may determine a second correction coefficient according to a change condition of the indoor temperature within a preset time period, and a current change trend and a current change rate of the indoor temperature; it should be noted that, the present invention does not limit the specific determination manner, and a technician may set the correction factor according to the actual use requirement, and the second correction factor is determined according to the change condition of the indoor temperature within the preset time period, the current change trend of the indoor temperature, and the current change rate, which belongs to the protection scope of the present invention; for example, the second correction coefficient may be obtained by determining different corresponding equations according to the change conditions of the indoor temperature within a preset time period, and then substituting the current change trend and the current change rate of the indoor temperature into the equations for calculation.
As a preferable determination manner, the variation range of the indoor temperature within the preset time period may be determined by the maximum value and the minimum value of the indoor temperature within the preset time period. The positive and negative of the second correction coefficient can be determined according to the current change trend of the indoor temperature: if the indoor temperature is in an increasing trend, the second correction coefficient is a negative value; and if the indoor temperature is in a decreasing trend, the second correction coefficient is a positive value. In addition, the magnitude of the second correction coefficient can be determined according to the change amplitude of the indoor temperature within the preset time period and the current change rate of the indoor temperature, for example, a coefficient is determined according to the change amplitude of the indoor temperature within the preset time period, and then the coefficient is multiplied by the current change rate to obtain the second correction coefficient; the larger the variation range of the indoor temperature in the preset time period is, the larger the determined coefficient is, and the smaller the variation range of the indoor temperature in the preset time period is, the smaller the determined coefficient is.
Further, in step S5, the controller may correct the preset target temperature in the sleep mode according to the determined first correction coefficient and the second correction coefficient. It should be noted that the invention does not limit the specific modification manner, and the technical personnel can set the modification manner according to the actual use requirement; for example, the preset target temperature in the sleep mode may be directly multiplied by the first correction coefficient and the second correction coefficient to perform the correction, or the correction may be performed after determining the correction value according to the first correction coefficient and the second correction coefficient.
As a preferred modification manner, the controller may determine a first modification value according to the current outdoor temperature, the current indoor temperature, and the first modification coefficient, determine a second modification value according to the current indoor temperature and the second modification coefficient, and then calculate a sum of the first modification value, the second modification value, and the preset target temperature, where the sum is the modified target temperature.

Further, the control method further includes: and selectively adjusting the rotating speed of the indoor fan according to the correction amplitude of the preset target temperature.
Specifically, if the correction amplitude of the preset target temperature is larger than a preset correction amplitude, the rotating speed of the indoor fan is adjusted; and if the correction amplitude of the preset target temperature is smaller than or equal to the preset correction amplitude, not adjusting the rotating speed of the indoor fan.
It should be noted that, the specific value of the preset correction amplitude is not limited by the present invention, and the technical staff can set the value according to the actual use requirement; preferably, the preset correction amplitude is set to 1 ℃, that is, the rotation speed of the indoor fan is adjusted when the correction amplitude of the preset target temperature is greater than 1 ℃, and the rotation speed of the indoor fan is not adjusted when the correction amplitude of the preset target temperature is less than or equal to 1 ℃.

It can be understood that, even in the sleep mode, the air conditioner is divided into a cooling operation condition and a heating operation condition, and the cooling operation condition is determined when the indoor heat exchanger is used as an evaporator, and the heating operation condition is determined when the indoor heat exchanger is used as a condenser.
Further preferably, the rotation speed of the indoor fan is adjusted by 100rpm every time the preset target temperature is corrected by 1 ℃. Specifically, under the heating condition, the rotating speed of the indoor fan is increased by 100rpm when the preset target temperature is adjusted to 1 ℃ upwards; when the preset target temperature is adjusted downwards by 1 ℃, the rotating speed of the indoor fan is reduced by 100rpm; under the refrigeration working condition, the rotating speed of the indoor fan is reduced by 100rpm when the preset target temperature is adjusted to be 1 ℃ upwards; the rotation speed of the indoor fan is increased by 100rpm every time the preset target temperature is adjusted downward by 1 ℃.
