Specifically, the heat exchange threshold may include a cooling threshold and a heating threshold, the heat exchange threshold corresponding to the air conditioner in the cooling mode may be a cooling threshold, and the temperature threshold corresponding to the air conditioner in the heating mode may be a heating threshold. Under the condition that the average temperature reaches the refrigeration threshold value in the refrigeration mode, controlling the air conditioner to start the refrigeration mode; and controlling the air conditioner to start the heating mode under the condition that the average temperature reaches the heating threshold value in the cooling mode. Therefore, the temperature in the room is reduced or increased, the requirement of human comfort is met, and the intelligent level of the intelligent air conditioner is improved.
In the invention, the temperature of the room where the indoor unit 200 of the air conditioner is located can be obtained by the movable temperature detection device 300, and the obtained temperature is high in precision. The method calculates the average temperature and the temperature variance according to the temperatures of the preset positions, then judges whether the average temperature reaches a preset heat exchange threshold value, controls the air conditioner to start a heat exchange mode if the average temperature reaches the preset heat exchange threshold value, further determines the air supply mode of the indoor unit 200 of the air conditioner to the preset positions according to the temperature variance, and controls the indoor unit 200 to operate according to the corresponding air supply mode, so that the temperature of the room where the indoor unit 200 is located is uniform, and the temperature meets the requirement of the comfort level of a human body.
In some embodiments of the present invention, the obtaining of the temperatures detected by the movable temperature detecting device 300 in the plurality of preset positions of the room in which the indoor unit 200 of the air conditioner is located in the above step S302 specifically includes: constructing a two-dimensional coordinate system in a room where an indoor unit 200 of the air conditioner is located; planning a driving route comprising a plurality of preset positions in a two-dimensional coordinate system; the method comprises the steps of controlling the movable temperature detection device 300 to run along a running route and detect the position of the movable temperature detection device 300, and controlling the movable temperature detection device 300 to detect and acquire the temperature when the movable temperature detection device 300 runs to any preset position, so that the temperatures of a plurality of preset positions can be acquired.
The starting point to the end point of the traveling route may correspond to all air supply positions of the left and right flaps of the indoor unit 200. Specifically, the left and right flaps may have a plurality of air supply positions from one side to the other side of the indoor unit 200, and the plurality of air supply positions correspond to the plurality of air supply regions, respectively. The starting point to the end point of the driving route corresponds to the air supply positions of all the left and right swing blades of the air conditioner. The starting point and the ending point of the driving route may be the preset positions mentioned above, or may be other points on the driving route, and the invention is not limited thereto. The preset positions can correspond to the air supply positions one by one, so that the air supply positions of the left and right swing blades of the indoor unit 200 can be adjusted according to the temperatures of the preset positions, and directional air supply of the indoor unit 200 to the preset positions is realized.
In addition, a plurality of preset positions in the room can be set to be more distributed, so that the average temperature and the temperature variance calculated according to the temperatures at the plurality of preset positions in the subsequent step S304 can be more accurate.
In addition, for the above-mentioned position detection of the movable temperature detection device 300, in practical applications, the detection modes include, but are not limited to, GPS positioning, base station positioning, WiFi positioning, IP positioning, RFID tag identification positioning, bluetooth positioning, and acoustic positioning.
Taking WiFi as an example to determine the position detected by the movable temperature detection device 300, a plurality of wireless stations, that is, AP stations, may be specifically set in the room where the indoor unit 200 is located, and each wireless station is in data connection with the movable temperature detection device 300. The position of the movable temperature detection device 300 relative to each wireless workstation can be determined according to the signal intensity of each wireless workstation, and then the position of the movable temperature detection device 300 in a room can be determined according to the position of the movable temperature detection device 300 relative to each wireless workstation.

Wherein, the temperature variance is higher than the preset variance threshold value, which indicates that the temperature in the room is relatively uneven. In this case, when the air conditioner is in the cooling mode, the air supply mode of the indoor unit 200 is determined to be directional air supply to the preset position with the highest temperature among the plurality of preset positions, so that the average temperature and the temperature variance of the room can be reduced as soon as possible, and the comfort experience of the human body is improved; for the air conditioner in the heating mode, the air supply mode of the indoor unit 200 is determined to be directional air supply to the preset position with the lowest temperature in the plurality of preset positions, so that the average temperature and the temperature variance can be improved as soon as possible, and the comfort experience of the human body is improved.
A temperature variance below a predetermined variance threshold indicates that the temperature in the room is relatively uniform. In this case, the average temperature may be increased or decreased, and thus, the indoor unit 200 may be controlled to sequentially and directionally supply air to a plurality of predetermined positions regardless of the cooling mode or the heating mode of the air conditioner, so that the average temperature may be increased or decreased as quickly as possible.
Under the condition that the average temperature reaches the preset heat exchange threshold and the temperature variance is higher than the preset variance threshold, after the indoor unit is controlled to operate according to the corresponding mode, the movable temperature detection device 300 can be controlled to run back and forth along the above-mentioned running route until the average temperature is detected not to meet the preset heat exchange threshold and the temperature variance is detected to be smaller than the preset variance threshold. The movable temperature detection device 300 is controlled to run back and forth along the running route, so that the change conditions of the average temperature and the temperature variance can be known in time, and the air conditioner can be closed in time when the average temperature does not meet the preset heat exchange threshold and the temperature variance is smaller than the preset variance threshold.
And under the condition that the average temperature reaches the preset heat exchange threshold value and the temperature variance is lower than the preset variance threshold value, controlling the movable temperature detection device 300 to run back and forth along the running route in the same way until the average temperature is detected not to meet the preset heat exchange threshold value, and turning off the air conditioner.
In some embodiments of the present invention, for step S306 above, in case the average temperature does not reach the preset heat exchange threshold, it may be determined whether the temperature variance is higher than the preset variance threshold; if yes, the indoor unit 200 of the air conditioner is controlled to directionally supply air to the preset position with the highest temperature in the plurality of preset positions.
In this case, if the temperature variance is higher than the preset variance threshold, that is, the temperature in the room is relatively uneven, the indoor unit 200 is controlled to directionally supply air to the preset position with the highest temperature among the plurality of preset positions. So as to promote the air flow in the room and make the temperature in the room uniform.
And under the condition that the average temperature does not reach the preset heat exchange threshold value and the temperature variance is higher than the preset variance threshold value, controlling the movable temperature detection device 300 to run back and forth along the running route in the same way until the temperature variance is detected to be smaller than the preset variance threshold value, and turning off the air conditioner.
