For example, if the season of the area where the air conditioner 10 is located is winter, and the type of clothes indicated by the clothes type information of the target interaction user is a thin clothes type, the operating condition type is a heating operating condition; if the season of the area where the air conditioner 10 is located is winter, and the clothes type indicated by the clothes type information of the target interaction user is a thick clothes type, the working condition type is a common air supply working condition; if the season of the area where the air conditioner 10 is located is summer, the operation condition types are all the cooling operation conditions no matter the clothes type indicated by the clothes type information of the target interactive user is a thin clothes type or a thick clothes type. If the season of the area where the air conditioner 10 is located is autumn or spring, the working condition types are common air supply working conditions no matter the clothes type indicated by the clothes type information of the target interaction user is a thin clothes type or a thick clothes type.
The step of determining the target operation parameter of the air conditioner 10 according to the operation condition type includes: acquiring a preset parameter corresponding relation, wherein the parameter corresponding relation specifies target operation parameters of the air conditioner 10 corresponding to each working condition type, the target operation parameters at least comprise target operation temperature and target operation humidity, and determining the target operation parameters of the air conditioner 10 according to the parameter corresponding relation. The target operation temperature refers to a temperature to which the indoor environment can be adjusted when the air conditioner 10 is operated. For example, the target operating temperature may be set to 26 ℃. The air conditioner 10 may operate at the target operating temperature to achieve or maintain the temperature of the indoor environment at 26 c.
The target operating temperature of the air conditioner 10 corresponding to the cooling condition may be 26 deg.c and the target operating humidity may be 40%. Because the application scene of the refrigeration working condition is generally summer, the temperature of the indoor environment is higher, and when the air conditioner 10 operates according to the target operation parameters of the temperature of 26 ℃ and the humidity of 40%, a comfortable air atmosphere can be created for the indoor environment, the target interaction users can be helped to relieve fatigue and relieve difficulties quickly, and the power consumption can be saved.
The target operating temperature corresponding to the heating condition may be 24 deg.c and the target operating humidity may be 70%. Because the application scenario of the refrigeration condition is generally winter, the temperature of the indoor environment is relatively low, and when the air conditioner 10 operates according to the target operation parameters of 24 ℃ and 70% of humidity, a comfortable air atmosphere can be created for the indoor environment, the target interaction user can be helped to relieve fatigue and relieve difficulties quickly, and the power consumption can be saved.
The target operation parameters of the air conditioner 10 are configured according to different working condition types, so that the air conditioner 10 can operate the awakening mode according to actual use requirements, the use requirements of the awakening function can be met, energy conservation can be realized, and the intelligent degree is improved.
In order to determine the target operation parameters corresponding to each working condition type, the inventor selects a plurality of test operation temperatures (24 ℃, 26 ℃, 28 ℃ and 30 ℃) under each working condition type, respectively selects a plurality of test operation humidities (40%, 55% and 70%) under each test operation temperature to carry out testing, and detects and records the fatigue degree of a target interactive user under each test condition.
FIG. 4 is a graph of the correspondence between the fatigue level of a target interactive user and the test operating temperature and the test operating humidity, according to one embodiment of the present invention. The ordinate in the figure is the fatigue level value P, each dashed box represents a test operation temperature, and the height of the square column in each dashed box represents the fatigue level value corresponding to different test operation humidities (40%, 55%, 70% in sequence from left to right). The dotted line frame K101 is a heating condition (24 ℃), the dotted line frame K102 is a cooling condition (26 ℃), the dotted line frame K103 is a heating condition (28 ℃), and the dotted line frame K104 is a cooling condition (30 ℃).
Under each working condition type, the fatigue degree value under each test condition can be obtained by controlling the air conditioner 10 to operate according to different test operation temperatures and different test operation humidities and analyzing the fatigue degree of the target interactive user under each test condition. The lower the fatigue degree value is, the lower the sleepiness degree of the target interaction user is, and the better the working state is. The test operating temperature and the test operating humidity corresponding to the lowest value of the fatigue degree at each operation type may be used as the target operating parameters of the air conditioner 10 corresponding to each operation type.
In the step S306, the step of determining the target operation parameter of the air conditioner 10 according to the yawning frequency of the target interactive user may include: and judging whether the yawning frequency of the target interactive user exceeds a second set threshold value, if so, determining that the air conditioner 10 needs to start a fresh air mode, and determining target operation parameters of the air conditioner 10 according to the yawning frequency of the target interactive user, wherein the target operation parameters at least comprise a target fresh air volume. For example, the second set time period may be 1min, and the second set threshold may be any value within a range of 2 to 5 times.
When the yawning frequency of the target interaction user is high, the air conditioner 10 is used for inputting fresh air into the indoor environment, so that the oxygen content in the indoor environment air can be increased, the effects of refreshing and restoring consciousness and relieving fatigue are achieved, and the peculiar smell generated by yawning can be properly dissipated, so that the air quality of the indoor environment is favorably improved, and the mental state of the target interaction user is further improved.
The fresh air mode may be configured with a plurality of air volume levels in advance, and may include, for example, a high air volume level and a low air volume level in which the air volume decreases in sequence. In the step of determining the target fresh air volume of the air conditioner 10 according to the yawning frequency of the target interactive user, the target fresh air volume may be in a high air volume class when the yawning frequency exceeds a third set threshold, and the target fresh air volume may be in a low air volume class when the yawning frequency does not exceed the third set threshold. The third threshold is larger than the second threshold, and may be any value within a range of 3 to 10 times, for example.
Step S308, controlling the air conditioner 10 to operate according to the target operation parameters, where the target operation parameters include a target operation temperature, a target operation humidity, and/or a target fresh air volume. The target operating temperature and the target operating humidity of the air conditioner 10 may be determined according to the blinking frequency of the target interaction user, and the target fresh air volume of the air conditioner 10 may be determined according to the yawning frequency of the target interaction user. Controlling the air conditioner 10 to operate according to the target operation parameters may refer to controlling the air conditioner 10 to adjust the operation state according to the target operation parameters, that is, if at least one of the target operation parameters determined according to the state parameters of the target interaction user is different from the initial operation parameters, for example, only the target operation parameters different from the initial operation parameters may be adjusted, and the other operation parameters are not adjusted.
If the blink frequency of the target interaction user is less than the first set threshold and the yawning frequency of the target interaction user does not exceed the second set threshold, the target operation temperature and the target operation humidity of the air conditioner 10 can be determined according to the blink frequency of the target interaction user, and the air conditioner 10 can be controlled to operate according to the determined target operation temperature and the determined target operation humidity, that is, only the target operation temperature and the target operation humidity are adjusted on the basis of the initial operation parameters, and the initial fresh air volume before the wake-up mode is started is used as the target operation temperature and the target fresh air volume.
If the blink frequency of the target interaction user is less than the first set threshold and the yawning frequency of the target interaction user exceeds the second set threshold, the target operation temperature and the target operation humidity of the air conditioner 10 can be determined according to the blink frequency of the target interaction user, the target fresh air volume of the air conditioner 10 can be determined according to the yawning frequency of the target interaction user, and the air conditioner 10 can be controlled to operate according to the determined target operation temperature, target operation humidity and target fresh air volume, namely, the target operation temperature, target operation humidity and target fresh air volume are adjusted on the basis of the initial operation parameters.
If the blinking frequency of the target interaction user is not less than the first set threshold and the yawning frequency of the target interaction user exceeds the second set threshold, the target fresh air volume of the air conditioner 10 can be determined according to the yawning frequency of the target interaction user, and at this time, the air conditioner 10 can be controlled to operate according to the determined target fresh air volume, that is, only the target fresh air volume is adjusted on the basis of the initial operation parameters, and the initial operation temperature and the initial operation humidity before the wake-up mode is started are taken as the target operation temperature and the target operation humidity.
After the step of controlling the air conditioner 10 to operate according to the target operation parameter, the control method further includes: and acquiring an exit signal of the air conditioner 10 exiting the wake-up mode, and controlling the air conditioner 10 to operate according to initial operation parameters before the wake-up mode is started, wherein the initial operation parameters at least comprise an initial operation temperature, an initial operation humidity and an initial fresh air volume. The exit signal for the air conditioner 10 to exit the awake mode may be sent after the awake mode is operated for the third set time period. The third set time period can be any value within the range of 10-30 min.
For example, if the air conditioner 10 is in the shutdown state before the wake-up mode is started, the air conditioner 10 is recovered to the shutdown state after exiting the wake-up mode; if the initial operation temperature of the air conditioner 10 before the wake-up mode is started is 26 ℃ (cooling), the initial operation humidity is 60%, and the initial fresh air volume is of a low air volume level, after the wake-up mode is exited, the air conditioner 10 is controlled to perform dehumidification according to the cooling temperature of 26 ℃ and the humidity of 60%, and supply fresh air according to the low air volume level.
In some optional embodiments, when the air conditioner 10 is controlled to start operating according to the target operating parameter, the status parameter of the target interactive user may also be detected, and if the blinking frequency of the target interactive user is greater than or equal to the first set threshold and the duration exceeds the fourth set duration, the target interactive user may be considered to be free from the sleepy state, and at this time, an exit signal of the wake-up mode may be issued.
