[0002] With global warming, extreme weather events occur frequently, and outdoor environmental temperature fluctuations intensify. In modern families, air conditioners are the main equipment for regulating indoor temperature, and their use frequency and intensity are rising. However, since the indoor temperature is usually kept constant, when users frequently enter and exit the air-conditioned room, they will experience large temperature difference changes, leading to increased physiological regulation burden on the human body, especially for the elderly, children and other groups with weak body temperature regulation ability, which can easily cause colds, cardiovascular diseases and other problems.

[0003] Existing air conditioner control systems rely on indoor temperature feedback for adjustment, lack dynamic perception of outdoor environmental temperature and prediction ability of user behavior, and cannot actively adjust the indoor temperature before the user enters or exits the room, thereby reducing the discomfort caused by temperature difference. Therefore, there is an urgent need for an air conditioner control method that can intelligently adjust according to user behavior and indoor-outdoor temperature difference changes to improve user comfort and health protection.

[0004] Although existing technologies also control indoor temperature in combination with outdoor temperature, such as the application file with patent publication number CN120947174A, which provides a compressor frequency control method, device and air conditioning system of an air conditioner, the control method includes obtaining the current indoor temperature, current compressor frequency and current outdoor temperature; based on the current indoor temperature, current compressor frequency and current outdoor temperature, determining the next indoor temperature corresponding to the next running stage; determining the temperature difference between the next indoor temperature and the preset target temperature; in the case where the temperature difference is greater than the preset threshold, based on the temperature difference and the preset temperature difference, adjusting the running frequency of the compressor to obtain the next compressor frequency. The present application predicts the next indoor temperature of the next running stage to realize early prediction of temperature change trend, and then calculates the temperature difference between the next indoor temperature and the preset target temperature to dynamically adjust the compressor frequency, effectively reducing the fluctuation of indoor temperature and improving user comfort; and by optimizing the running frequency of the compressor, the energy utilization efficiency is significantly improved.

DETAILED DESCRIPTION

[0022] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application are described in detail below with reference to the drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0023] The prior art solution to the air conditioner control method that cannot be intelligently adjusted according to the change of indoor and outdoor temperature difference includes an automatic temperature difference adjustment mode and a manual temperature difference adjustment mode.

[0024] The automatic temperature difference adjustment mode is that the air conditioner automatically adjusts the opening degree of the refrigerant valve according to the outdoor temperature, a preset temperature difference value and a target operation mode, so that the difference between the indoor temperature and the outdoor temperature is maintained as the preset temperature difference value. The preset temperature difference value is a temperature difference value that can be accepted by the user, so as to reduce the discomfort and adverse effects on health caused by too large temperature difference when the personnel go in and out of the house.

[0025] The manual temperature difference adjustment mode is that the air conditioner automatically adjusts the opening degree of the refrigerant valve and the opening degree change speed according to the first target indoor temperature, the target time and the number of steps input by the user, so that the indoor temperature reaches the first target indoor temperature in a step-by-step manner within the target time. The user can flexibly adjust the first target indoor temperature according to the needs, and the possibility of causing discomfort and affecting the health of the indoor personnel due to too fast change of the indoor temperature can be reduced.

[0026] However, the manual temperature difference condition mode is not intelligent and requires the user to input various parameters, which is often forgotten by the user when going out or coming in. In the automatic temperature difference adjustment mode, the indoor temperature is always close to the outdoor temperature, which does not meet the needs of the user. For example, after the user enters the room, the user may hope that the indoor temperature is a suitable temperature, at which time the user still needs to manually select the conventional cooling mode or the conventional heating mode.

[0027] To solve this problem, with reference to Figure 1 The embodiment of the present application provides an air conditioner control method based on indoor and outdoor temperature difference, which comprises the following steps: S11: when a first preset condition is triggered, entering an in-out mode, the in-out mode is used to control the absolute value of the temperature difference between the indoor temperature and the target outdoor temperature to be less than a preset temperature difference value; S12: When in the entering and exiting mode, if a second preset condition is triggered, the entering and exiting mode is exited.

[0028] The air conditioner control method based on indoor and outdoor temperature difference provided by the embodiments of the present application enters an entering and exiting mode when a first preset condition is triggered, and the entering and exiting mode is used to control the absolute value of the temperature difference between the indoor temperature and the target outdoor temperature to be less than a preset temperature difference. When in the entering and exiting mode, if a second preset condition is triggered, the entering and exiting mode is exited. The embodiments of the present application set the entering and exiting mode, and in the entering and exiting mode, the indoor temperature and the target outdoor temperature can be ensured to be close, so that the user will not experience a large temperature difference when entering or exiting the room, thereby avoiding the situation that the physiological regulation burden of the human body is increased, especially for the elderly, children and other groups of people with weak body temperature regulation ability, which can avoid triggering the situation of catching a cold and cardiovascular disease, and ensure the health of the human body. The exiting of the entering and exiting mode can also ensure that the air conditioner can provide a suitable indoor environment for the user when the user does not enter or exit the door.

[0029] Embodiment one: An air conditioner control method based on indoor and outdoor temperature difference, comprising: When a first preset condition is triggered, an entering and exiting mode is entered, and the entering and exiting mode is used to control the absolute value of the temperature difference between the indoor temperature and the real-time outdoor temperature to be less than a preset temperature difference. As a preferred implementation manner of the present application, when the entering and exiting mode is entered, it comprises: The indoor temperature and the outdoor temperature are acquired in real time; the indoor temperature and the outdoor temperature are acquired by temperature sensors arranged in the indoor and outdoor, for example, the existing air conditioner generally sets temperature sensing bags in the indoor and outdoor, so that the indoor temperature and the outdoor temperature can be acquired based on the temperature sensing bags. Of course, the indoor temperature can also be acquired based on networking (communicating with the device with a temperature sensor in the indoor), and the outdoor temperature can be acquired based on weather forecasting.

[0030] When the absolute value of the temperature difference between the indoor temperature and the outdoor temperature is greater than a preset temperature difference, the running state of the air conditioner is determined based on the indoor temperature and the outdoor temperature. When the absolute value of the temperature difference between the indoor temperature and the outdoor temperature is greater than a preset temperature difference, the indoor and outdoor temperature difference is large, and the physiological regulation burden of the user is large when entering or exiting the door, so the indoor and outdoor temperature difference needs to be reduced at this time.

[0031] Specifically, the determination of the running state of the air conditioner based on the indoor temperature and the outdoor temperature comprises: When the indoor temperature is greater than the outdoor temperature, the air conditioner is controlled to run in a cooling mode; when the indoor temperature is greater than the outdoor temperature, the indoor temperature is high and the outdoor temperature is low, so the air conditioner is controlled to run in a cooling mode to reduce the indoor temperature, so that the absolute value of the temperature difference between the indoor temperature and the outdoor temperature is less than a preset temperature difference. The embodiments of the present application do not improve the prior art for how the air conditioner runs in a cooling mode, and will not be described here in detail.

[0032] When the indoor temperature is less than the outdoor temperature, the air conditioner is controlled to run in a heating mode. When the indoor temperature is less than the outdoor temperature, the indoor temperature is low and the outdoor temperature is high, so the air conditioner is controlled to run in a heating mode to increase the indoor temperature, so that the absolute value of the temperature difference between the indoor temperature and the outdoor temperature is less than a preset temperature difference. The embodiments of the present application do not improve the prior art for how the air conditioner runs in a heating mode, and will not be described here in detail.

[0033] Further, it further comprises: After the air conditioner runs in a determined running state for a preset time length, a first indoor temperature change rate under the current compressor frequency is obtained, and a second indoor temperature change rate is calculated based on the temperature difference, the second indoor temperature change rate = (temperature difference - preset temperature difference) / remaining time, the remaining time being the time difference between the time of leaving or entering and the current time; it should be noted that the preset temperature difference here is the same as the preset temperature difference in the entering mode, that is, the absolute value of the temperature difference between the indoor temperature and the real-time outdoor temperature is less than the preset temperature difference.

[0034] The air conditioner needs to run in a determined running state for a preset time length to ensure that the calculated first indoor temperature change rate is the indoor temperature change rate under the current compressor frequency, because if the first indoor temperature change rate is directly calculated, the compressor may not have run in the corresponding running state, or although it has run in the corresponding running state, its cooling or heating capacity is not stable because it has just started.

[0035] Wherein, the first indoor temperature change rate can be calculated once every preset period, such as a preset period of 60s, the indoor temperature obtained before 60s is t1, and the current indoor temperature is t2, the first indoor temperature change rate = (t2-t1) / 60. The second temperature change rate is calculated to make the indoor temperature change more stable, so the difference between the current temperature difference and the preset temperature difference is used for calculation, which ensures that the indoor temperature change rate is relatively uniform in the remaining time, and the indoor temperature will not fluctuate greatly, and the user experience is better.

[0036] When the first indoor temperature change rate is greater than the second indoor temperature change rate, the compressor frequency is reduced; when the first indoor temperature change rate is less than the second indoor temperature change rate, the compressor frequency is increased.

[0037] When the first indoor temperature change rate is greater than the second indoor temperature change rate, it indicates that the indoor temperature change rate is fast under the current compressor frequency, which can cause fluctuations in the indoor temperature, and thus the compressor frequency is reduced. When the compressor frequency is reduced, the first preset frequency value can be reduced every interval of a preset time length. When the first indoor temperature change rate is less than the second indoor temperature change rate, it indicates that the indoor temperature change rate is slow under the current compressor frequency, and thus the absolute value of the temperature difference between the indoor temperature and the real-time outdoor temperature cannot be less than the preset temperature difference, and thus the compressor frequency is increased. When the compressor frequency is increased, the second preset frequency value can be increased every interval of a preset time length. The first preset frequency value and the second preset frequency value can be equal according to actual needs.

[0038] In one embodiment, when the time difference between the door-out time or the door-in time and the current time is less than a first preset time difference, it is determined that the first preset condition is triggered.

[0039] That is, the scheme of the embodiment of the present application is to perform early control when the user has not left the house or has not entered the house, and thus when the air conditioner is used, the indoor and outdoor temperature difference is generally large. If immediate control is performed, the indoor temperature fluctuation is large, which is not conducive to user experience, and is equivalent to the user directly entering the indoor environment from the outdoor environment or entering the outdoor environment from the indoor environment, and the physiological burden is still large. In addition, the air conditioner temperature regulation has a certain hysteresis, and in fact, immediate regulation cannot be achieved. Therefore, generally, regulation needs to be performed in advance. For example, when there are 10 minutes to the door-in time, the in-out mode is entered, or when there are 10 minutes to the door-out time, the in-out mode is entered.

[0040] In another embodiment, when it is detected that the distance of the user to the house is less than a preset distance, it is determined that the first preset condition is triggered. The specific implementation is as follows: a GPS or Bluetooth positioning function is integrated in the air conditioner control system, and when the user leaves the house by a certain distance (such as 500 meters) or approaches the house by a certain distance, the in-out mode is entered. The user only needs to set the indoor and outdoor temperature difference, and does not need to manually set the door-in time and the door-out time, so that a more intelligent temperature control experience is achieved.

[0041] It should be noted that the above two embodiment modes can be used alone or together, that is, when any one condition is met, it is determined that the first preset condition is triggered.

[0042] In one embodiment, the door-in time and the door-out time are set by the user. That is, the present application needs the user to set the door-in time and the door-out time and the indoor and outdoor temperature difference (the preset temperature difference).

[0043] In another embodiment, the method further comprises: obtaining weather, temperature and current date of a preset time period in which the current time is located; wherein the preset time period is a division of 24 hours in a day into a plurality of preset time periods, such as every half hour as a preset time period. The purpose of dividing the preset time period is to predict the time of entering or leaving the door in some time period, such as 7-8 am and 5-6 pm (specifically according to user setting or based on historical data analysis), which needs to be predicted. While other times such as 11 pm to 6 am the next day, these time periods do not need to be predicted. Generally, only one prediction is made in a time period, in order to ensure sufficient time, generally, the prediction is made as soon as the preset time period is entered, but in order to deal with unexpected situations, such as it does not rain when predicting, but it starts to rain after predicting, at this time the user may leave earlier or enter later, therefore, in order to deal with unexpected weather conditions, if the weather condition changes in the same target preset time period, the prediction will be made again. Wherein, the target preset time period is the time period that needs to be predicted.

[0044] inputting the current time, weather, temperature and current date into a pre-constructed prediction model to obtain the predicted entering time or leaving time.

[0045] That is, in the embodiment of the application, a prediction model is constructed in advance, and the entering time and leaving time are directly output by the prediction of the prediction model. For example, an initial neural network model is constructed, which includes an input layer, a connection layer and an output layer, wherein the input layer includes 4 neurons for inputting the current time, weather, temperature and current date, the connection layer is three layers, and the number of neurons in each layer is 8, 10 and 8 layers in turn, the parameters in the connection layer are randomly set (adjusted through subsequent training), and the output layer only includes one neuron. Wherein, the training sample is historical data, wherein the historical data includes the specific time of each entering or leaving, the date of the day, the weather, the temperature and the current date of the time period in which the specific time is located. The loss function adopts accuracy. Wherein, the historical data can be obtained in many ways, such as camera detection whether to enter or leave the door. Networked to obtain weather condition and current date, temperature bag to obtain temperature condition.

[0046] It should be noted that the weather refers to the weather in a preset time period, mainly divided into two cases: severe weather and normal weather. Among them, the severe weather is the weather above moderate rain, the weather above heavy snow, the weather of heavy fog and the weather of strong wind. The normal weather is the weather except the severe weather; during training, the weather in the historical data is labeled according to the two labels; of course, each kind of weather can be specifically divided, but the more the division, the more difficult the model converges. The reason for using weather as input is that the user's in-out door plan will be affected in severe weather, so the in-out door time will be different from usual.

[0047] And the current time is used as input to predict whether it is in or out.

[0048] The main reason for using temperature is to distinguish between winter and summer. The user's in-out door time also varies in different seasons.

[0049] And the date is mainly used to distinguish weekdays, ordinary Saturdays and holidays, so the date needs to be labeled as a working day, an ordinary Saturday or a holiday in the training set.

[0050] In addition, during training, in order to prevent overfitting, the parameters of a neuron in each training connection layer are randomly set to 0.

[0051] In addition, in one embodiment, the first preset time difference is a fixed value set by the user.

[0052] And in another embodiment, the first preset time difference uses a dynamic value. Because when using a fixed time length, the time of entering the in-out mode is consistent, but since the temperature difference between the indoor temperature and the target outdoor temperature may be different, if the difference is large, it may cause the indoor temperature to change too fast per unit time, affecting the user experience. Although the above can be adjusted by the compressor frequency, but in extreme cases, it may exceed the adjustment capacity of the compressor frequency, such as the compressor frequency has reached the upper limit, therefore the first preset time difference can be adjusted to adjust the time of entering the in-out mode, and in extreme cases, a part of the time is increased.

[0053] Specifically as follows: When the time difference between the out-door time or the in-door time and the current time is less than a second preset time difference, the temperature difference between the indoor temperature and the target outdoor temperature is obtained, wherein the second preset time difference is greater than the first preset time difference; the second preset time difference is set to facilitate determining when to start determining the first preset time difference.

[0054] The first preset time difference is determined based on the absolute value of the temperature difference, and the greater the absolute value of the temperature difference, the greater the first preset time difference.

[0055] When in the access mode, if a second preset condition is triggered, the access mode is exited.

[0056] When the current time is a leaving time or an entering time, it is determined that the second preset condition is triggered. And / or, after detecting that the user enters or leaves, it is determined that the second preset condition is triggered.

[0057] In addition, when the sleep mode is running, an outdoor temperature is acquired. In a first preset time period before the sleep mode starts, a temperature difference between the indoor temperature and the outdoor temperature is controlled to be a first preset temperature difference; and in a second preset time period before the sleep mode ends, the temperature difference between the indoor temperature and the outdoor temperature is controlled to be a second preset temperature difference, wherein the first preset temperature difference is greater than the second preset temperature difference.

[0060] The air conditioning control method based on indoor and outdoor temperature difference provided in this application embodiment enters an entry / exit mode when a first preset condition is triggered. This entry / exit mode controls the absolute value of the temperature difference between the indoor temperature and the target outdoor temperature to be less than a preset temperature difference value. While in the entry / exit mode, if a second preset condition is triggered, the entry / exit mode is exited. This application solution sets up an entry / exit mode, which ensures that the indoor temperature is close to the target outdoor temperature. This prevents users from experiencing large temperature changes when entering or leaving the room, avoiding increased physiological regulatory burden on the body. This is especially beneficial for the elderly, children, and other groups with weaker thermoregulation abilities, preventing colds and cardiovascular diseases, thus ensuring human health. Exiting the entry / exit mode also ensures that the air conditioner provides a suitable indoor environment when the user is not entering or leaving the room.

[0061] The following provides a specific implementation method: System parameters: Ti—Indoor ambient temperature, °C; To—Outdoor ambient temperature, °C; TΔ—Preset indoor-outdoor temperature difference, °C; TΔ'—Real-time indoor-outdoor temperature difference, °C; Ti'—Expected indoor temperature, °C; t—User-defined time for entering / exiting the air-conditioned room, in minutes; t'—The remaining time to enter / exit the air-conditioned room, in minutes; V1—Average indoor temperature adjustment rate, °C / min; V2—Indoor temperature change rate, °C / min.

[0062] Its regulation logic includes: Indoor temperature sensor: Used to detect the current temperature in an air-conditioned room; Outdoor temperature sensor: used to detect the outdoor ambient temperature of an air-conditioned room; Control module: Used to receive temperature sensor data and calculate temperature difference based on user-defined parameters; User input interface: Supports setting the estimated time t for entering / exiting the air-conditioned room and the desired indoor-outdoor temperature difference TΔ using a remote control or remote terminal; Air conditioning execution module: Adjusts the indoor temperature according to the instructions of the control module.

[0063] The specific implementation process is as follows: Figure 2 As shown: 1. Users can set the estimated time t for entering / exiting the air-conditioned room and the desired indoor / outdoor temperature difference TΔ via remote control or remote terminal; 2. If the user sets the indoor-outdoor temperature difference TΔ≤0 ℃, it indicates that the user expects the indoor temperature to be lower than the outdoor environment temperature, and the air conditioner runs in the "cooling" mode; if the user sets the indoor-outdoor temperature difference TΔ>0 ℃, it indicates that the user expects the indoor temperature to be higher than the outdoor environment temperature, and the air conditioner runs in the "heating" mode. 3. The system continuously collects indoor and outdoor temperature data, calculates the current indoor-outdoor temperature difference TΔ', and calculates the expected indoor temperature Ti' according to the outdoor environment temperature To and the expected indoor-outdoor temperature difference TΔ, and takes the integer as the target indoor temperature for the air conditioner to run. 4. The control module counts the time after the user sets the "in-out mode", and if the remaining time t' of the current "in-out mode" is not 0, the adjustment program is run in a loop, the system continuously monitors the indoor and outdoor temperature changes, and dynamically adjusts the air conditioner running parameters to ensure that the temperature difference is controlled within the user set range, i.e. according to the expected indoor temperature Ti', the average temperature adjustment rate V1 and the indoor temperature change rate V2, the compressor frequency is increased or decreased, so that the air-conditioned room reaches the expected indoor-outdoor temperature difference in the expected time, and the indoor temperature changes relatively evenly.

[0064] 5. If the current remaining time t' = 0, exit the "in-out mode", and the air conditioner state after exiting can be determined according to the air conditioner state when the "in-out mode" is set. If it is in the "on" state when it is set, the user may need to go out, and the air conditioner will automatically shut down after exiting the "in-out mode"; if it is in the "off" state when it is set, the user may be about to enter the door, and the air conditioner will continue to run according to the historical settings of the corresponding mode after exiting the "in-out mode".

[0065] In addition, when the user enables the indoor-outdoor temperature difference adjustment sleep mode, the indoor temperature dynamically responds to the real-time outdoor temperature, and during the night sleep period, the indoor temperature is maintained at a lower set value to promote the user to fall asleep; during the morning wake-up period, the indoor temperature is raised to a higher set value to promote the user to wake up. Specifically, the sleep mode can gradually lower the indoor temperature after the user falls asleep, and gradually raise the indoor temperature before the user's preset wake-up time, thereby effectively improving sleep depth and accelerating the user's wake-up process.

[0066] Embodiment two: An air conditioner control method based on indoor-outdoor temperature difference, comprising: When a first preset condition is triggered, enter the in-out mode, the in-out mode is used to control the absolute value of the temperature difference between the indoor temperature and the predicted outdoor temperature to be less than a preset temperature difference.

[0067] As a preferred implementation of the present application, when entering the in-out mode, it includes: Obtain the predicted outdoor temperature at the time of entering or leaving the door; that is, the predicted outdoor temperature is the outdoor temperature when the user enters and leaves the door.

[0068] The absolute value of the temperature difference between the indoor temperature at the door entry time or the door exit time and the predicted outdoor temperature is less than the preset temperature difference.

[0069] The predicted outdoor temperature is obtained from a weather forecast or predicted by a trained temperature prediction model, which is not limited in the embodiments of the present application. For example, a meteorological data interface is introduced in the air conditioning control system to obtain the predicted outdoor temperature data for the next 24 hours. The control module combines the historical indoor-outdoor temperature difference trend and future weather changes to adjust the indoor temperature in advance to cope with possible extreme weather changes. For example, the meteorological data shows that the outdoor temperature will change suddenly, and using the real-time outdoor environment temperature will cause the expected indoor temperature to change suddenly, while only using the predicted outdoor temperature corresponding to the door exit time can avoid this temperature change.

[0070] In one embodiment, when the time difference between the door exit time or the door entry time and the current time is less than a first preset time difference, it is determined that the first preset condition is triggered.

[0071] That is, the scheme of the embodiments of the present application is to control in advance when the user has not yet left the house or has not yet entered the house, so when using the air conditioner, the indoor-outdoor temperature difference is generally large, and if it is controlled immediately, the indoor temperature fluctuation is large, which is not conducive to user experience, and it is equivalent to the user directly entering the indoor environment from the outdoor environment or entering the outdoor environment from the indoor environment, which still has a large physiological burden. In addition, the air conditioning temperature regulation has a certain hysteresis, and in fact it is impossible to realize immediate adjustment. Therefore, in general, it is necessary to adjust in advance. For example, 10 minutes before the door entry time, enter the in-out mode, or 10 minutes before the door exit time, enter the in-out mode.

[0072] In another embodiment, when it is detected that the distance of the user to the house is less than a preset distance, it is determined that the first preset condition is triggered. The specific implementation is as follows: integrate the GPS or Bluetooth positioning function in the air conditioning control system, when the user leaves the house for a certain distance (such as 500 meters) or approaches the house for a certain distance, enter the in-out mode, the user only needs to set the indoor-outdoor temperature difference, and does not need to manually set the door entry time or the door exit time, to realize a more intelligent temperature control experience.

[0073] It should be noted that the above two embodiment modes can be used alone or together, that is, when any one condition is met, it is determined that the first preset condition is triggered.

[0074] In one embodiment, the door entry time and the door exit time are set by the user. That is, the present application needs the user to set the door entry time and the door exit time, and the indoor-outdoor temperature difference (the preset temperature difference).

[0075] In another embodiment, it further includes: obtaining weather, temperature and current date of a preset time period in which the current time is located; the preset time period is a time period obtained by dividing 24 hours of a day, for example, each half hour; the purpose of dividing the preset time period is to predict the time of entering or leaving the door in some time period, for example, 7-8 am and 5-6 pm (specifically according to user setting or based on historical data analysis), and to predict the time of entering or leaving the door in other time periods, for example, 11 pm to 6 am of the next day. Generally, the time of entering or leaving the door is predicted only once in a time period, in order to ensure sufficient time, the prediction is generally performed as soon as the preset time period is entered, but in order to deal with unexpected situations, for example, it does not rain when the prediction is performed, but it rains after the prediction is performed, at this time, the user may leave earlier or enter later, therefore, in order to deal with unexpected weather conditions, if the weather condition changes in the same target preset time period, the prediction is performed again. The target preset time period is a time period that needs to be predicted.

[0076] inputting the current time, weather, temperature and current date into a pre-constructed prediction model to obtain the predicted entering or leaving door time.

[0077] That is, in the embodiment of the present application, a prediction model is constructed in advance, and the entering or leaving door time is directly output by the prediction of the prediction model. For example, an initial neural network model is constructed, which includes an input layer, a connection layer and an output layer, the input layer includes four neurons for inputting the current time, weather, temperature and current date, the connection layer has three layers, the number of neurons in each layer is 8, 10 and 8 respectively, the parameters in the connection layer are randomly set (adjusted through subsequent training), and the output layer includes only one neuron. The training sample is historical data, wherein the historical data includes the specific time of each entering or leaving door, the date of the day, the weather, temperature and current date of the time period in which the specific time is located. The loss function adopts accuracy. The historical data can be obtained in various ways, for example, whether the door is entered or left is detected by a camera. The weather condition and current date are obtained through networking, and the temperature condition is obtained through a temperature sensing bag.

[0078] It should be noted that the weather refers to the weather in a preset time period, which is mainly divided into two cases: severe weather and normal weather. The severe weather is weather above moderate rain, weather above moderate snow and weather above heavy fog. The normal weather is weather other than the severe weather; during training, the weather in the historical data is labeled according to the two labels; of course, each weather can be specifically divided, but the more the division, the more difficult the model converges. The reason for using weather as input is that the user's entering or leaving door plan will be affected in severe weather, so the entering or leaving door time will be different from usual.

[0079] The current time is used as an input to predict whether it is an entry or exit.

[0080] The temperature is mainly used to distinguish between winter and summer. The user's entry and exit times are different in different seasons.

[0081] The date is mainly used to distinguish between weekdays, ordinary Saturdays and holidays, so the date needs to be labeled as a weekday, an ordinary Saturday, or a holiday in the training set.

[0082] In addition, during training, to prevent overfitting, the parameters of a neuron in the layer are randomly set to 0 for each training.

[0083] In addition, in one embodiment, the first preset time difference is a fixed value set by the user.

[0084] In another embodiment, the first preset time difference uses a dynamic value. When a fixed time period is used, the entry and exit modes are consistent, but the temperature difference between the indoor temperature and the target outdoor temperature may be different, which may cause the indoor temperature to change too quickly per unit time, affecting the user experience. Although this can be adjusted by the compressor frequency, in extreme cases, it may exceed the adjustment capacity of the compressor frequency, such as when the compressor frequency has reached the upper limit, so the first preset time difference can be adjusted to adjust the time of entering the entry and exit modes, and in extreme cases, a portion of the time is increased.

[0085] Specifically as follows: When the time difference between the exit time or the entry time and the current time is less than a second preset time difference, the temperature difference between the indoor temperature and the target outdoor temperature is obtained, wherein the second preset time difference is greater than the first preset time difference; the second preset time difference is set to facilitate determining when to start determining the first preset time difference.

[0086] The first preset time difference is determined based on the absolute value of the temperature difference, and the greater the absolute value of the temperature difference, the greater the first preset time difference.

[0087] When in the entry and exit mode, if a second preset condition is triggered, the entry and exit mode is exited.

[0088] When the current time is the exit time or the entry time, it is determined that the second preset condition is triggered. And / or, after detecting that the user has entered or exited, it is determined that the second preset condition is triggered.

[0089] In addition, when the sleep mode is running, the outdoor temperature is obtained. In a first preset time period after the sleep mode starts, a temperature difference between the indoor temperature and the outdoor temperature is controlled as a first preset temperature difference; and in the sleep mode ending at a second preset time period, the temperature difference between the indoor temperature and the outdoor temperature is controlled as a second preset temperature difference, wherein the first preset temperature difference is greater than the second preset temperature difference.
