In S101, the set historical time is a set length of time that has occurred in the past, the set historical time may be 24 hours, 48 hours, 72 hours, 96 hours, or the like in the past, the set historical time is an integral multiple of 24, that is, the set historical time may be approximately 1 day, 2 days, 3 days, or the like, and the temperature sensor measures the outdoor temperature in real time and stores the measured outdoor temperature in the memory. In S102, the set future time is a set upcoming time period, and the set future time may be within 24 hours of the future. The upcoming time of the highest temperature and the lowest temperature of the outdoor temperature is a time point at which the next highest temperature and the lowest temperature of the outdoor temperature occur. The purpose of S102 is to determine the time when the highest and lowest temperatures of the outdoor temperature occur within 24 hours in the future. In S103, the operation of the air conditioner is controlled with reference to the time when the highest temperature and the lowest temperature occur.

In an embodiment of the present invention, the determining the upcoming times of the highest temperature and the lowest temperature of the outdoor temperature according to the outdoor temperature within the set historical time includes:
s121: sequentially dividing the set historical time into N time periods with the size of 24 hours according to the time sequence, wherein N is a positive integer;
s122: determining occurrence times of the highest temperature and the lowest temperature in each time period according to the outdoor temperature within the set historical time;
s123: determining a highest temperature time interval between the highest temperatures and a lowest temperature time interval between the lowest temperatures in the adjacent time periods according to the occurrence time of the highest temperature and the lowest temperature;
s124: determining the upcoming time of the highest temperature and the lowest temperature within the set future time according to the highest temperature time interval, the lowest temperature time interval, the time of occurrence of the highest temperature and the lowest temperature.
In S121, the setting history time may be divided into 1 day, 2 days, 3 days, 4 days, etc., and when the setting history time is divided into 3 days, then the corresponding setting history time includes the first day, the second day, and the third day, and may also correspond to 0 to 72 hours.
In S122, in order to make a more accurate determination, the value of N is generally equal to or greater than 2, and in the first day, if the time when the highest temperature appears is earlier than the time when the lowest temperature appears, the time when the highest temperature and the lowest temperature appear on the first day is the occurrence time of the highest temperature and the lowest temperature on the first day.
Determining a time at which the lowest temperature occurs in an Nth time period as an occurrence time of the lowest temperature in an Nth-1 th time period when the time at which the highest temperature occurs is later than the time at which the lowest temperature occurs within the set history time. For example, on the first day, the highest temperature occurs later than the lowest temperature occurs, and then the lowest temperature occurs on the second day at the time of the lowest temperature. The benefit that sets up like this lies in, through revising the time that the minimum temperature appears, carries out the selection of the most accurate minimum low temperature through complete temperature acquisition, avoids the incompleteness of temperature data of the first day to lead to the inaccuracy that the time of occurrence of minimum low temperature was confirmed.
And when the highest temperature appears later than the lowest temperature in the set historical time, determining the highest temperature appearing for the first time in the future as the occurrence time of the highest temperature in the Nth time period. For example, on the first day, the highest temperature occurs later than the lowest temperature, and then the highest temperature on the third day occurs at the time of the upcoming highest temperature. The advantage that sets up like this lies in, through revising the time that the maximum temperature appears, carries out the selection of the most accurate maximum temperature through complete temperature acquisition, avoids the incompleteness of the last day temperature data to lead to the inaccurate of the emergence time determination of maximum temperature.
Here, as shown in fig. 4 and 5, when the time of the maximum temperature occurs earlier than the time of the minimum temperature, and the time difference Δ t1 between the occurrence of the maximum temperature of the 24h-48h internal and external temperatures and the occurrence of the maximum temperature of the 0-24h internal and external temperatures is less than 40h, the occurrence times of the maximum temperature and the minimum temperature of the 0-24h (the first day) are recorded as the time (i) and the time (ii) in fig. 4, and the occurrence times of the maximum temperature and the minimum temperature of the 24h-48h (the second day) and the 48h-72h (the third day) are recorded as the time (iii), the time (iv), the time (v) and the time (iv), respectively.
As shown in fig. 6 and 7, when the time of the highest temperature is later than the time of the lowest temperature, and the time difference Δ t2 between the lowest temperature of the internal and external temperatures within 48h-72h and the time of the lowest temperature within 24h-48h is less than 32h, the time of the highest temperature and the time of the lowest temperature within 0 h-24 h (the first day) are recorded as the time (i) and the time (ii) in fig. 4, and the time of the highest temperature and the time of the lowest temperature within 24h-48h (the second day) and the time of the highest temperature and the time of the lowest temperature within 48h-72h (the third day) are recorded as the time (iii), the time (iv), the time (v), the time (c) and.
In S123, the maximum temperature time interval is a time interval of a maximum temperature between adjacent time periods; the lowest temperature time interval is a time interval of lowest temperature between adjacent time periods. For example, the maximum temperature time interval may be a first high temperature time interval of the maximum temperature occurrence times of the first and second days, or may be a second high temperature time interval of the maximum temperature occurrence times of the second and third days. Similarly, the minimum temperature time interval may be a first minimum temperature time interval between the minimum temperature occurrence times of the first day and the second day, or may be a second minimum temperature time interval between the minimum temperature occurrence times of the second day and the third day. Here, the maximum temperature time interval is an average of the first high temperature time interval and the second high temperature time interval; the minimum temperature time interval is an average of the first and second low temperature time intervals. Of course, the maximum temperature time interval is an average value of the maximum temperature time intervals of all adjacent time periods; the minimum temperature time interval is the average of the minimum temperature time intervals of all adjacent time periods. Therefore, the accuracy of the estimation of the highest temperature and lowest temperature occurrence time can be ensured.
In S124, the upcoming time of the highest temperature is the latest highest temperature occurrence time plus the highest temperature time interval; the imminent time of the lowest temperature is the latest time of the lowest temperature occurrence plus the lowest temperature time interval.
The advantage of this arrangement is that the occurrence time of the highest temperature and the lowest temperature in the future is estimated by processing the occurrence time of the highest temperature and the lowest temperature in the past several days, so as to form the machine time and guide the control of the air conditioner.
In an embodiment of the present invention, the controlling the air conditioner according to the upcoming time of the highest temperature and the lowest temperature further includes: and when the air conditioner is in a refrigeration mode, controlling the running frequency of a compressor of the air conditioner to be reduced and controlling the running rotating speed of an outdoor fan of the air conditioner to be reduced at the third preset time after the upcoming time of the highest temperature.
Here, the third preset time may be 5 to 10 hours, and specifically, the third preset time may be 6 hours, 8 hours, 10 hours, or the like. That is, if the current time is the maximum temperature, after a third preset time, the night is entered, the maximum operating frequency of the compressor of the air conditioner is controlled to be reduced by 5-10Hz, and the maximum operating speed of the outdoor fan of the air conditioner is controlled to be reduced by 50-100 rpm. The advantage that sets up like this lies in, after the third preset time of highest temperature, the load in the room is less relatively, and outer loop temperature reduces gradually, and the compressor operation of air conditioner is lower frequency just can obtain higher ability output, simultaneously, reduces the noise of fan rotational speed in order to reduce the off-premises station, can reduce the noise interference to the user, has promoted user's life experience.

Here, the fourth preset time may be 4 to 10 hours, and specifically, the fourth preset time may be 4 hours, 6 hours, 8 hours, 10 hours, or the like. That is, if the current time is the lowest temperature, the operating frequency of the compressor and the operating rotational speed of the outdoor fan are controlled to be restored to normal values after a fourth preset time. The advantage of setting up like this is that, confirm the time of daytime according to the time of occurrence of the coldest temperature to make the air conditioner resume normal operation correspondingly, realized the automated control of air conditioner.

Here, the fifth preset time may be 5 to 10 hours, and specifically, the fifth preset time may be 6 hours, 8 hours, 10 hours, or the like. That is, if the current time is the maximum temperature, after a fifth preset time, the outdoor temperature is reduced and the heating capacity of the air conditioner is attenuated when the night is entered, and in order not to affect the comfort of the user, the compressor of the air conditioner is controlled to operate at the maximum operating frequency and the outdoor fan of the air conditioner is controlled to operate at the maximum operating speed. From this, after the fifth preset time of minimum temperature, the load in the room is less relatively, and outer loop temperature reduces gradually, and the heating capacity of air conditioner can attenuate, and increase fan rotational speed is in order to guarantee indoor heating, has promoted user's sleep and has experienced.
When the air conditioner is in a heating mode, the lowest temperature is controlled to reduce the highest operating frequency of the compressor during the sixth preset time after the upcoming time. Here, the sixth preset time may be 5 to 10 hours, and specifically, the sixth preset time may be 6 hours, 8 hours, 10 hours, or the like.
