The indoor temperature of each room may be obtained by a temperature sensor on an air conditioner installed in each room, or in some smart home systems, the indoor temperature of each room may be obtained by providing a temperature sensor independently for each room.
The indoor temperature of each room may be periodically obtained, for example, the step of obtaining the indoor temperature of each room may be performed once every 5 s.
In some application scenarios, if the temperature difference value between the first indoor temperature and the indoor temperatures of other rooms is out of a first preset temperature range, controlling the first air conditioner according to the target temperature, the first indoor temperature and the temperature difference value; and if the temperature difference value between the first indoor temperature and the indoor temperatures of other rooms is within a first preset temperature range, continuously obtaining the temperature difference value between the first indoor temperature and the indoor temperatures of other rooms.
The temperature difference between the first indoor temperature and the indoor temperatures of the other rooms is outside the first preset temperature range, which means that the difference between the first indoor temperature and the indoor temperatures of the other rooms is greater than the upper limit value of the first preset temperature range or less than the lower limit value of the first preset temperature range.
The temperature difference between the first indoor temperature and the indoor temperatures of the other rooms is within a first preset temperature range, which means that the difference between the first indoor temperature and the indoor temperatures of the other rooms is smaller than or equal to an upper limit value of the first preset temperature range, or is larger than or equal to a lower limit value of the first preset temperature range.
In the above application scenario, the temperature difference between the first indoor temperature and the indoor temperatures of the other rooms is outside the first preset temperature range, including: the temperature difference value between the first indoor temperature and the indoor temperature of one part of rooms is within a first preset temperature range, and the temperature difference value between the first indoor temperature and the indoor temperature of the other part of rooms is outside the first preset temperature range; or the temperature difference value between the first indoor temperature and the indoor temperatures of all other rooms is within the first preset temperature range. In this case, the first indoor temperature of the first room is adjusted by controlling the first air conditioner.
In the above application scenario, the first predetermined temperature range may be [ -3 ℃,3 ℃ ], [ -4 ℃,4 ℃ ], or [ -5 ℃,5 ℃ ].
In other application scenarios, an average value of the indoor temperatures of a plurality of rooms may be obtained, and if the difference between the indoor temperature of one room and the average value is greater than a preset temperature range, it is determined to perform the method for controlling the air conditioner. For example, the difference between the first indoor temperature of the first room and the average value is greater than the preset temperature range, and the first indoor temperature of the first room is adjusted by controlling the first air conditioner.

The target temperatures of the plurality of rooms may be obtained by: an average temperature of the indoor temperatures of the plurality of rooms is obtained, and a target temperature is determined according to the average temperature. The average temperature may be determined as the target temperature, or a difference between the average temperature and a preset temperature may be used as the target temperature during heating, and a sum of the average temperature and another preset temperature may be used as the target temperature during cooling, so that the temperatures of the rooms may be rapidly equalized. Therefore, the temperature of each room can be balanced, the cold and hot alternation feeling of the user when the user moves in each room is reduced, and the use experience of the user is improved.
In an application scenario where the volumes of the rooms are different, the target temperatures of the rooms can be obtained as follows: the volume of each room is obtained, the volume of each room is used as the weight of the indoor temperature, the weighted average value of the indoor temperatures of the plurality of rooms is obtained, and the target temperature is determined according to the weighted average value. For example, the weighted average value may be determined as the target temperature, or a difference value between the weighted average value and a preset temperature may be used as the target temperature during heating, and a sum of the weighted average value and another preset temperature may be used as the target temperature during cooling, so that the temperatures of the rooms may be more quickly equalized.
Under the condition that the increased or decreased temperature is the same, the heat or cold quantity required by the room with larger volume is more, and the target temperature determined by the method can more accurately reflect the current energy value of all the rooms, so that the temperature of each room can be more quickly balanced.

Wherein the first indoor temperature reaching the target temperature may include: and if the first temperature difference between the target temperature and the first indoor temperature is within a second preset temperature range, determining that the first indoor temperature reaches the target temperature. The first temperature difference is within a second predetermined temperature range, which means that the first temperature difference is greater than or equal to a lower limit of the second predetermined temperature range, and the first temperature difference is less than or equal to an upper limit of the second predetermined temperature range, where the second predetermined temperature range is less than the first predetermined temperature range, for example, the second predetermined temperature may be [ -1 ℃,1 ℃).

s201, determining a first control quantity according to a first temperature difference value between the target temperature and the first indoor temperature.
For example, a first temperature difference between the target temperature and the first indoor temperature is input to the first controller and a first output amount of the first controller is obtained, and the first output amount is determined as a first control amount. The first controller here may be a proportional-Integral-derivative (PID) controller.
In practical applications, the first control quantity may be an operating frequency of the compressor, a rotating speed of an indoor fan, and other parameters of each actuator in the air conditioner.
S202, determining a second control quantity according to the first control quantity and the first indoor temperature difference value.
That is, the first control amount is compensated by the first indoor temperature difference, and the compensated first control amount is used as the second control amount.
Optionally, determining the second control quantity according to the first control quantity and the first indoor temperature difference value comprises: obtaining an adjusting control quantity corresponding to the first indoor temperature difference value; obtaining the difference between the first control quantity and the control quantity of the adjusting control quantity, or the sum of the control quantities; the difference between the control amounts, or the sum of the control amounts is determined as a second control amount. Alternatively, determining the second control amount based on the first control amount and the first indoor temperature difference may include: the corresponding relation of the first control quantity, the first indoor temperature difference and the second control quantity is prestored in a database, and the first control quantity and the first indoor temperature difference are inquired in the database, so that the second control quantity corresponding to the first control quantity and the first indoor temperature difference can be obtained.

The magnitude relation between the target temperature and the first indoor temperature may reflect the operation mode of the first air conditioner, for example, if the target temperature is greater than the first indoor temperature and meets the trigger condition of the method for controlling the air conditioner, the first air conditioner may be in a heating mode; if the target temperature is less than the first indoor temperature and the triggering condition of the method for controlling the air conditioner is met, the first air conditioner may be in a cooling mode.
Alternatively, determining a difference between the control amounts by which the first control amount and the adjustment control amount are obtained or determining a sum of the control amounts by which the first control amount and the adjustment control amount are obtained, based on the magnitude relation, includes: determining to obtain a difference between the first control amount and the control amount of the adjustment control amount if the target temperature is greater than the first indoor temperature; if the target temperature is less than the first indoor temperature, it is determined that the sum of the first control amount and the control amount of the adjustment control amount is obtained.
If the target temperature is higher than the first indoor temperature, the first air conditioner is in a heating mode, the first air conditioner in the heating mode comprises two scenes, namely: the first air conditioner and the second air conditioner are both in a heating mode; the second scenario is as follows: the first air conditioner is in a heating mode, and the second air conditioner is in a cooling mode.

Correspondingly, if the first indoor temperature T1 is smaller than the second indoor temperature T2, the first indoor temperature difference value delta T1 is smaller than 0, the adjusting control quantity is smaller than zero, at the moment, the adjusting control quantity is subtracted from the first control quantity to obtain a control quantity difference, namely, the control quantity difference is an absolute value obtained by adding the adjusting control quantity on the basis of the first control quantity, the second control quantity is larger than the first control quantity, the heating rate of the first air conditioner is improved, the heating rate of the first room is improved, and the first temperature difference value delta T1 of the first room and the second room is further reduced.
Under the condition that the first air conditioner is in a heating mode and the second air conditioner is in a cooling mode, as the first air conditioner and the second air conditioner have a common target temperature, the first indoor temperature T1 is lower than the second indoor temperature T2, the first indoor temperature difference delta T1 is smaller than 0, the adjusting control quantity is smaller than zero, the adjusting control quantity is subtracted from the first control quantity, namely, the absolute value of the adjusting control quantity is added on the basis of the first control quantity, namely, the second control quantity is larger than the first control quantity, the heating rate of the first air conditioner is improved, the heating rate of the first room is improved, and further, the first temperature difference delta T1 between the first room and the second room is reduced.
If the target temperature is less than the first indoor temperature, the first air conditioner is in a cooling mode, and the first air conditioner in the cooling mode comprises two scenes, wherein the first scene is as follows: the first air conditioner and the second air conditioner are both in a refrigeration mode; in the second scenario, the first air conditioner is in a cooling mode, and the second air conditioner is in a heating mode.
Under the condition that the first air conditioner and the second air conditioner are both in the refrigerating mode, if the first indoor temperature T1 is greater than the second indoor temperature T2, the first indoor temperature difference delta T1 is greater than 0, the adjusting control quantity is greater than zero, at the moment, the adjusting control quantity is added to the first control quantity, the second control quantity is greater than the first control quantity, the refrigerating speed of the first air conditioner is improved, the cooling speed of the first room is improved, and the first temperature difference delta T1 between the first room and the second room is reduced. If the first indoor temperature T1 is less than the second indoor temperature T2, the first indoor temperature difference Delta T1 is less than 0, the adjusting control quantity is less than zero, at the moment, the first control quantity is added to the adjusting control quantity, and the fact that the absolute value of the adjusting control quantity is subtracted on the basis of the first control quantity is substantial, so that the second control quantity is less than the first control quantity, the refrigerating speed of the first air conditioner is reduced, the cooling rate of the first room is reduced, and the first temperature difference between the first room and the second room is reduced.
Under the condition that the first air conditioner is in a cooling mode and the second air conditioner is in a heating mode, as the second air conditioner and the second air conditioner have a common target temperature, the first indoor temperature T1 is greater than the second indoor temperature T2, the first indoor temperature difference Delta T1 is greater than 0, the adjusting control quantity is greater than zero, and the adjusting control quantity is added to the first control quantity, so that the second control quantity is greater than the first control quantity, the cooling rate of the first air conditioner is improved, the cooling rate of the first room is improved, and the first temperature difference Delta T1 of the first room and the second room is reduced.

In the above technical solution, the control target is the first air conditioner, in practical application, the same scheme is adopted to control the second air conditioner while controlling the first air conditioner, and the parameters related to the first air conditioner are adaptively modified into the parameters related to the second air conditioner, that is, the modified technical solution can be used to control the second air conditioner.
For example, the following technical scheme can be adopted to control the second air conditioner: determining a third control amount according to a second temperature difference value between the target temperature and a second indoor temperature of a second room in which the second air conditioner is located; determining a third control quantity according to the third control quantity and the second indoor temperature difference value; and controlling the second air conditioner according to a third control amount. And the second indoor temperature difference delta T2= T2-T1, wherein T2 is the second indoor temperature, and T1 is the first indoor temperature.
