Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0032] like Figure 1 As shown, in a first aspect, embodiments of this application provide an air conditioner control method, which includes steps S10 to S30. The type of air conditioner 1 can be determined according to actual needs, and can be, for example, a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, etc., and embodiments of this application do not limit this.

[0033] S10: Determine the standard speed of the indoor fan and the weighting coefficient of the standard speed based on the current indoor temperature and the set temperature.

[0034] Here, the current indoor temperature can be determined in real time by a temperature sensor installed on the indoor side. The set temperature is the target temperature that the indoor environment is expected to reach. It can be an input temperature value that is manually set by the user through a remote control, control panel, smart terminal, etc., or it can be a comfortable temperature value that is automatically generated by the air conditioner 1 based on operating conditions such as user habits and current environmental information.

[0035] Here, a standard calculation model can be pre-set in the control system of air conditioner 1 to determine the standard speed and weighting coefficient of the indoor fan based on the current indoor temperature and the set temperature. After obtaining the current indoor temperature and the set temperature, the current indoor temperature and the set temperature can be input into the standard calculation model to determine the standard speed and the weighting coefficient of the standard speed of the indoor fan.

[0036] In some embodiments, when the air conditioner 1 is in cooling mode, if the current indoor temperature is higher than the set temperature and the difference between the current indoor temperature and the set temperature is large, the standard speed of the indoor fan can be set to a larger speed value, and the weighting coefficient corresponding to the standard speed is larger; if the current indoor temperature is close to or equal to the set temperature, the standard speed of the indoor fan can be set to a smaller speed value, and the weighting coefficient corresponding to the standard speed is smaller; if the current indoor temperature is lower than the set temperature, the standard speed of the indoor fan can be set to an even smaller speed value, and the weighting coefficient corresponding to the standard speed is even smaller.

[0037] In some embodiments, when the air conditioner 1 is in heating mode, if the current indoor temperature is lower than the set temperature and the difference between the current indoor temperature and the set temperature is large, the standard speed of the indoor fan can be set to a larger speed value, and the weighting coefficient corresponding to the standard speed is larger; if the current indoor temperature is close to or equal to the set temperature, the standard speed of the indoor fan can be set to a smaller speed value, and the weighting coefficient corresponding to the standard speed is smaller; if the current indoor temperature is higher than the set temperature, the standard speed of the indoor fan can be set to a smaller speed value, and the weighting coefficient corresponding to the standard speed is smaller.

[0038] S20: Determine the target speed of the indoor fan based on the standard speed of the indoor fan, the weighting coefficient of the standard speed, indoor occupant information, and the comfort speed variation model.

[0039] Here, indoor occupant information can be determined in real time by human body sensing devices installed on the indoor side. These devices may include distance sensors, pyroelectric sensors, etc. The types of information included in the indoor occupant information can be determined according to actual needs, and this application embodiment does not limit this. In some embodiments, the indoor occupant information includes the number of indoor occupants, the distribution area where the occupants are located, and the time the occupants spend in the distribution area. Here, the indoor area in front of the air conditioner 1 can be pre-divided into multiple distribution areas, which are sequentially arranged from the air conditioner 1 along its orientation. The distance between any two distribution areas and the air conditioner 1 is unequal, such that the multiple distribution areas are arranged layer by layer around the air conditioner 1 from the inside out.

[0040] In some examples, the indoor area in front of air conditioner 1 can be pre-divided into at least three distribution zones. These at least three distribution zones may include a first distribution zone, a second distribution zone, and a third distribution zone extending outwards from air conditioner 1. The first distribution zone is positioned around and adjacent to air conditioner 1; the second distribution zone is positioned around the side of the first distribution zone away from air conditioner 1 and connected to it; and the third distribution zone is positioned around the side of the second distribution zone away from air conditioner 1 and connected to it. Thus, the indoor occupant information may include the number of occupants, the distribution zone where each occupant is located, and the duration of their stay in each distribution zone. For example, the indoor occupant information may include that there are three people in the room, one person is in the first distribution zone and has been there for two minutes, no one is in the second distribution zone, and the other two are in the third distribution zone and have been there for five minutes.

[0041] Here, the comfort speed variation model is a model of the indoor fan speed variation that makes indoor occupants feel comfortable. This model can be predetermined based on, for example, historical operating data and / or experimental test data of the air conditioner 1. The type of comfort speed variation model can be determined according to actual needs, and can include speed variation curves, prediction models based on data training, etc. This application embodiment does not limit this. For example, historical operating data and / or experimental test data of the air conditioner 1 under different speeds and various indoor occupant information can be used as sample data. The model can be trained using learning algorithms such as linear regression, artificial neural network, or decision tree algorithms to obtain a comfort speed variation model in the form of, for example, a linear regression model, an artificial neural network model, or a decision tree model. As another example, historical operating data and / or experimental test data of the air conditioner 1 under different speeds and various indoor occupant information can be curve-fitted to obtain a comfort speed variation model in the form of a speed variation curve.

[0042] Based on the standard speed of the indoor fan, the weighting coefficient of the standard speed, the information of the indoor occupants, and the comfort speed variation model, the speed value of the indoor fan that makes the current indoor occupants feel comfortable can be determined, which is the target speed of the indoor fan.

[0043] S30: Control the indoor fan to operate at the target speed mentioned above.

[0044] After determining the target speed of the indoor fan, the indoor fan can be controlled to operate at the target speed. When the indoor fan is running at the target speed, the air outlet of the air conditioner 1 can be blown to the location of each person in the room at a more suitable wind speed, so that the temperature in different areas is more similar, and the comfort of people in different locations is better taken into account.

[0045] Compared with related technologies, the air conditioner control method provided in this application embodiment can automatically adjust the speed of the indoor fan according to the current indoor temperature and the set temperature. When determining the target speed of the indoor fan, the information of indoor occupants and the comfort speed change model are taken into account. Therefore, the determined target speed can make indoor occupants in various positions feel comfortable. Thus, when performing automatic fan speed adjustment, the synchronous air supply needs of different areas can be better taken into account, eliminating or at least greatly reducing the temperature difference between different areas, and effectively improving the user's comfort.

[0046] like Figure 2 As shown, in some embodiments, S10 may include S11 to S13.

[0047] S11: Determine the temperature difference between the current indoor temperature and the set temperature, as well as the temperature range within which the temperature difference exists.

[0048] Here, multiple temperature difference intervals can be pre-set in the control system of air conditioner 1, and a corresponding indoor fan speed value can be set for each temperature difference interval. In some examples, multiple temperature difference intervals can be set, such as a first temperature difference interval less than or equal to a first temperature difference threshold, a second temperature difference interval greater than the first temperature difference threshold and less than or equal to a second temperature difference threshold, a third temperature difference interval greater than the second temperature difference threshold and less than or equal to a third temperature difference threshold, and a fourth temperature difference interval greater than the third temperature difference threshold.

[0049] For example, when the air conditioner 1 is in cooling mode, the indoor fan speed values ​​corresponding to the first temperature difference range, the second temperature difference range, the third temperature difference range, and the fourth temperature difference range gradually increase. The specific values ​​of the first temperature difference threshold, the second temperature difference threshold, and the third temperature difference threshold can be determined according to actual needs, and this application embodiment does not limit them; for example, the first temperature difference threshold can be 0℃.

[0050] For example, when the air conditioner 1 is in heating mode, the indoor fan speed values ​​corresponding to the first temperature difference range, the second temperature difference range, the third temperature difference range, and the fourth temperature difference range gradually decrease. The specific values ​​of the first temperature difference threshold, the second temperature difference threshold, and the third temperature difference threshold can be determined according to actual needs, and this application embodiment does not limit them; for example, the third temperature difference threshold can be 0°C.

[0051] S12: Determine the standard speed of the indoor fan based on the temperature difference range.

[0052] After determining the temperature difference range between the current indoor temperature and the set temperature, the corresponding indoor fan speed value can be determined, and this indoor fan speed value can be used as the standard speed of the indoor fan.

[0053] S13: Determine the weighting coefficient of the standard speed based on the temperature difference between the current indoor temperature and the set temperature.

[0054] Here, a weight calculation model for determining the standard rotational speed based on the temperature difference between the current indoor temperature and the set temperature can be pre-set in the control system of air conditioner 1. After determining the temperature difference between the current indoor temperature and the set temperature, this temperature difference can be input into the weight calculation model to determine the weight coefficient of the standard rotational speed.

[0055] The specific steps for determining the target rotational speed of the indoor fan can be determined according to actual needs, and this application does not limit this. For example... Figure 3 As shown, in some embodiments, S20 may include S21 to S22.

[0056] S21: Determine the corrected speed of the indoor fan based on the standard speed of the indoor fan, the weighting coefficient of the standard speed, and the information of the people in the room.

[0057] Here, a speed correction model can be pre-set in the control system of air conditioner 1. This model takes the standard speed of the indoor fan, the weighting coefficient of the standard speed, and the information of the people in the room as input values, and the corrected speed of the indoor fan as the output value. In this way, after determining the standard speed of the indoor fan, the weighting coefficient of the standard speed, and the information of the people in the room, the standard speed of the indoor fan, the weighting coefficient of the standard speed, and the information of the people in the room can be input into the speed correction model to determine the corrected speed of the indoor fan.

[0058] S22: Based on the modified speed and comfort speed variation model of the indoor fan, the target speed of the indoor fan is determined by fitting.

[0059] After determining the corrected speed and comfort speed variation models for the indoor fan, these models can be fitted to obtain a smooth speed variation curve. With the time axis as the horizontal axis, the target speed of the indoor fan can be determined based on this curve. This target speed is determined comprehensively based on the current indoor temperature, set temperature, indoor occupant information, and the comfort speed variation model. This allows the indoor fan speed to automatically adjust to changes in the current indoor temperature, while also accommodating the synchronous airflow needs of different areas, eliminating or at least significantly reducing temperature differences between areas, and effectively improving user comfort.

[0060] The steps for determining the corrected rotational speed can be determined according to actual needs, and this application does not limit this aspect. For example... Figure 4 As shown, in some examples, S21 may include S211 to S212.

[0061] S211: Determine the indoor personnel distribution coefficient based on indoor personnel information.

[0062] Here, a personnel distribution coefficient calculation model can be pre-set in the control system of air conditioner 1. This model can take information such as the number of people indoors, their distribution areas, and their dwell time within those areas as inputs, and output a personnel distribution coefficient. The personnel distribution coefficient can be a single value reflecting the overall distribution of all people indoors, allowing the model to output a discrete value based on a single input; alternatively, it can be a series of values ​​reflecting the individual distribution of each person indoors, allowing the model to output an array of values ​​based on a single input, where each value represents the dwelling location and dwell time weight of each person indoors.

[0063] S212: Determine the corrected speed of the indoor fan based on the standard speed of the indoor fan, the weighting coefficient of the standard speed, and the indoor personnel distribution coefficient.

[0064] Here, the aforementioned speed correction model can use the standard speed of the indoor fan, the weighting coefficient of the standard speed, and the indoor occupant distribution coefficient as input values, and the corrected speed of the indoor fan as the output value. Thus, by inputting the standard speed of the indoor fan, the weighting coefficient of the standard speed, and the indoor occupant distribution coefficient into the speed correction model, the corrected speed of the indoor fan can be determined.

[0065] By setting S211 to S212, the corrected speed of the indoor fan can be determined more accurately, so that the determined corrected speed can better match the distribution of people in the room. In turn, the target speed determined based on the corrected speed can better take into account the distribution of people in the room. Thus, when the automatic fan speed is adjusted, the synchronous air supply needs of different areas can be better taken into account, eliminating or at least greatly reducing the temperature difference between different areas, and effectively improving the user's comfort.

[0066] like Figure 5 As shown, in some examples, the air conditioner control method may include S201 to S202 before S22.

[0067] S201: Determine the indoor personnel distribution type based on indoor personnel information.

[0068] Here, people can be categorized according to their different distribution patterns indoors, resulting in multiple indoor person distribution types. An indoor person distribution type database can then be established based on these pre-defined types. For example... Figure 9As shown, for example, the indoor area located in front of the air conditioner 1 can be pre-divided into at least three distribution areas as described above. The indoor personnel distribution type library can include multiple indoor personnel distribution types, which can include, for example, the following distribution types: only one of the first, second, and third distribution areas has people, while the remaining distribution areas are empty; the first distribution area is empty, while both the second and third distribution areas have people; both the first and second distribution areas have people, while the third distribution area is empty; both the first and third distribution areas have people, while the second distribution area is empty; the first, second, and third distribution areas all have people; and so on, without further listing. Furthermore, for the distribution types listed above, they can be further subdivided into multiple types based on the number of people in each distribution area and their stay time, to form a larger number and more detailed distribution types.

[0069] In this way, after obtaining the indoor personnel information, the indoor personnel distribution type corresponding to the indoor personnel distribution type can be determined in the indoor personnel distribution type library.

[0070] S202: Determine the comfort speed variation model corresponding to the indoor occupant distribution type.

[0071] Here, based on the indoor occupant distribution type database, and using, for example, historical operating data and / or experimental test data of air conditioner 1, a comfort speed variation model corresponding to that indoor occupant distribution type can be pre-determined. This results in multiple comfort speed variation models corresponding one-to-one with the aforementioned indoor occupant distribution types, and multiple comfort speed variation model databases can be established based on these models. Thus, after determining the indoor occupant distribution type, the corresponding comfort speed variation model can be determined from the comfort speed variation model database.

[0072] By setting S201 to S202, a comfortable speed variation model that matches the current indoor occupant distribution can be determined more accurately. Then, based on the comfortable speed variation model, a target speed that matches the current indoor occupant distribution can be determined. Thus, when automatically adjusting the fan speed, the synchronous air supply needs of different areas can be better taken into account, eliminating or at least greatly reducing the temperature difference between different areas, and effectively improving user comfort.

[0073] like Figure 6 As shown, in some other embodiments, S20 may include S21' to S24'.

[0074] S21': Determine the indoor personnel distribution type based on indoor personnel information.

[0075] The specific method of S21' can be found in the description of S201 above, and will not be repeated here.

[0076] S22': Based on the indoor occupant distribution type, determine the comfort speed variation model corresponding to that indoor occupant distribution type from the comfort speed variation model library.

[0077] The specific method of S22' can be found in the description of S202 above, and will not be repeated here.

[0078] S23': Based on the current speed change curve of the indoor fan and the comfort speed change model, fit and determine the target speed change curve.

[0079] Here, the current speed change curve of the indoor fan refers to the speed change curve where the current speed of the indoor fan is located. For example, for two adjacent times t0 and t1, the current speed change curve of the indoor fan at time t1 can be the target speed change curve determined by S23' at time t0. Based on the target speed change curve determined by S23' at time t0 and by S24' below, the target speed of the indoor fan at time t1 can be determined. The target speed of the indoor fan at time t1 is the current speed of the indoor fan at time t1.

[0080] By fitting the current speed change curve of the indoor fan to the comfort speed change model, a smooth speed change curve, i.e., the target speed change curve, can be determined. This target speed change curve is plotted on the time axis, and the target speed of the indoor fan can be determined based on this curve. Taking three consecutive moments t0, t1, and t2 as examples, the comfort speed change model determined at time t1 is fitted and corrected based on the current speed change curve of the indoor fan at time t1 (i.e., the target speed change curve determined by S23' at time t0). This results in a smooth speed change curve, i.e., the target speed change curve of the indoor fan at time t2. Following this target speed change curve allows the indoor fan to smoothly transition from its current speed at time t1 to the target speed at time t2, reducing the interference of fan speed adjustment on indoor users and achieving a better adjustment effect with no or no noticeable change in fan speed.

[0081] S24': Determine the target speed of the indoor fan based on the standard speed of the indoor fan, the weighting coefficient of the standard speed, and the target speed variation curve.

[0082] After determining the standard speed of the indoor fan, the weighting coefficient of the standard speed, and the target speed change curve, the target speed of the indoor fan can be determined. Based on this target speed, the indoor fan speed is adjusted so that it smoothly changes from the current speed to the target speed, reducing the interference of fan speed adjustment on indoor users and achieving a better adjustment effect with no or no noticeable change in the feeling of airflow.

[0083] like Figure 7 As shown, in some embodiments, before S20, the air conditioner control method may include S101 to S102.

[0084] S101: Divide the indoor area in front of the air conditioner 1 into multiple distribution zones.

[0085] Here, multiple distribution zones are arranged sequentially from air conditioner 1 along the orientation of air conditioner 1, and the distance between any two distribution zones and air conditioner 1 is not equal. For details on the division of these multiple distribution zones, please refer to the aforementioned description; further details will not be repeated here.

[0086] S102: Obtain indoor occupant information, including the number of indoor occupants, their distribution area, and the duration of their stay in that area. For details regarding the specific content of the indoor occupant information, please refer to the preceding description; it will not be repeated here.

The memory 20 stores a computer program, which, when executed by the processor 10, implements the air conditioner control method provided in any of the above embodiments. The type of air conditioner 1 can be determined according to actual needs, and can be, for example, a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, etc., and embodiments of this application do not limit this.

Specifically, processor 10 can be an integrated circuit chip with signal processing capabilities. The processor 10 can be a general-purpose processor, digital signal processor (DSP), application-specific integrated circuit (ASIC), off-the-shelf programmable gate array (FPGA), or other programmable logic device, discrete gate or transistor logic device, or discrete hardware component, and can implement or execute the methods, steps, and logic block diagrams disclosed in the embodiments of this application. The general-purpose processor can be a microprocessor or any conventional processor, and can be based on x86 architecture or ARM architecture.

[0090] Memory 20 may be volatile or non-volatile, or may include both. Non-volatile memory may be read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), or flash memory. Volatile memory may be random access memory (RAM) used as an external cache.

It should be noted that memory 20 of the methods described herein is intended to include, but is not limited to, these and any other suitable types of memory.
