Abstract
Description
Technical Field
[0001] This application relates to the field of temperature regulation technology, and in particular to an air conditioning control method, device, system, and air conditioner based on the indoor-outdoor temperature difference. Background Technology
[0002] With global warming and the increasing frequency of extreme weather events, outdoor temperatures are fluctuating more significantly. In modern homes, air conditioning, as the primary device for regulating indoor temperature, is being used more frequently and intensively. However, because indoor temperatures are typically kept constant, users experience significant temperature changes when frequently entering and leaving air-conditioned rooms. This increases the burden on the body's physiological regulation, especially for the elderly and children, whose thermoregulation abilities are weaker, making them more susceptible to colds, cardiovascular diseases, and other problems.
[0003] Existing air conditioning control systems mostly rely on indoor temperature feedback for adjustment, lacking the ability to dynamically sense outdoor ambient temperature and predict user behavior. They cannot proactively adjust the indoor temperature before users enter or leave the room, thus failing to reduce discomfort caused by temperature differences. Therefore, there is an urgent need for an air conditioning control method that can intelligently adjust based on user behavior and changes in indoor-outdoor temperature differences to improve user comfort and health.
[0004] While existing technologies also incorporate outdoor temperature control for indoor temperature, such as patent application CN120947174A which provides a compressor frequency control method, device, and air conditioning system for an air conditioner, the control method includes acquiring the current indoor temperature, current compressor frequency, and current outdoor temperature; determining the next indoor temperature corresponding to the next operating stage based on the current indoor temperature, current compressor frequency, and current outdoor temperature; determining the temperature difference between the next indoor temperature and a preset target temperature; and adjusting the compressor operating frequency based on the temperature difference and the preset temperature difference when the temperature difference is greater than a preset threshold, to obtain the next compressor frequency. This invention predicts the next indoor temperature for the next operating stage, thus predicting temperature change trends in advance. It then dynamically adjusts the compressor frequency by calculating the temperature difference between the next indoor temperature and the preset target temperature, effectively reducing indoor temperature fluctuations and improving user comfort. Furthermore, it significantly improves energy efficiency by optimizing the compressor operating frequency. However, although it incorporates outdoor temperature, its ultimate goal remains to maintain a constant indoor temperature and reduce indoor temperature fluctuations. Summary of the Invention
[0005] To overcome the shortcomings of the prior art, this application provides an air conditioning control method, device, system, and air conditioner based on the indoor-outdoor temperature difference, in order to solve the problem that the prior art relies on indoor temperature feedback for adjustment, lacks dynamic perception of outdoor ambient temperature and the ability to predict user behavior, and cannot actively adjust the indoor temperature before the user enters or leaves the room, thereby reducing the discomfort caused by temperature difference.

The second indoor temperature change rate = (temperature difference - preset temperature difference) / remaining time, where the remaining time is the time difference between the time of leaving or entering the room and the current time. 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.
[0010] As an optional implementation of this application, the target outdoor temperature is a predicted outdoor temperature, and when entering the entry / exit mode, it includes: Get the predicted outdoor temperature when you enter or leave the house; The absolute value of the temperature difference between the indoor temperature and the predicted outdoor temperature when controlling the entry or exit time is less than the preset temperature difference value.
[0011] As an optional implementation of this application, it also includes: When the time difference between the time of leaving or entering the house and the current time is less than the first preset time difference, the first preset condition is triggered. And / or, if the distance from the user to the house is detected to be less than a preset distance, the first preset condition is triggered.

[0014] As an optional implementation of this application, it also includes: When the current time is the time to leave or the time to enter, the second preset condition is determined to be triggered; And / or, after detecting that a user enters or leaves the room, determine that a second preset condition is triggered.

[0016] Secondly, an air conditioning control device based on indoor and outdoor temperature difference is provided, comprising: The entry / exit mode entry module is used to enter the entry / exit mode when a first preset condition is triggered. The entry / exit 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.

[0019] Beneficial effects: This application provides an air conditioning control method, device, system, and air conditioner based on indoor and outdoor temperature difference. When a first preset condition is triggered, an "entry / exit mode" is entered. This 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 mode is exited. This application's entry / exit mode ensures that the indoor temperature is close to the target outdoor temperature, preventing users from experiencing large temperature changes when entering or leaving the room. This avoids increasing the burden on the body's physiological regulation, especially for the elderly and children with weaker thermoregulation abilities, preventing colds and cardiovascular diseases, and 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. Attached Figure Description

Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be described in detail below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0023] Existing technologies for air conditioning control methods that cannot intelligently adjust based on changes in indoor and outdoor temperature differences include: automatic temperature difference adjustment mode and manual temperature difference adjustment mode.
[0024] The automatic temperature difference adjustment mode allows the air conditioner to automatically adjust the opening of the refrigerant valve based on the outdoor temperature, the preset temperature difference value, and the target operating mode, maintaining the temperature difference between the indoor and outdoor temperatures at the preset value. This preset temperature difference value is acceptable to the user, thus reducing discomfort and adverse health effects caused by large temperature differences when people enter or leave the house.
[0025] The manual temperature difference adjustment mode allows the air conditioner to automatically adjust the opening degree and the rate of change of the refrigerant valve based on the user-inputted target indoor temperature, target time, and number of temperature steps. This ensures that the indoor temperature reaches the target temperature in a step-by-step manner within the target time. Users can flexibly adjust the target indoor temperature as needed, and this mode can reduce the possibility of discomfort and health problems caused by rapid changes in indoor temperature.
[0026] However, the manual temperature difference mode is not intelligent, requiring users to input various parameters, which they often forget when leaving or entering a room. In automatic temperature difference mode, the indoor temperature remains close to the outdoor temperature, failing to meet user needs. For example, after entering a room, users may want a comfortable indoor temperature, requiring them to manually select either the regular cooling or heating mode.
[0027] To solve this problem, refer to Figure 1 This application provides an air conditioning control method based on indoor and outdoor temperature difference, including: S11: When the first preset condition is triggered, enter the entry / exit mode. The entry / exit 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 the preset temperature difference. S12: When in the entry / exit mode, if the second preset condition is triggered, the entry / exit mode will be exited.
[0028] The air conditioning control method based on indoor-outdoor temperature difference provided in this application embodiment allows the air conditioner to enter an in / out mode when a first preset condition is triggered. This in / out 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. If a second preset condition is triggered while in the in / out mode, the air conditioner exits the in / out mode. This application solution establishes an in / out mode, ensuring that the indoor temperature is close to the target outdoor temperature. This prevents users from experiencing significant temperature changes when entering or leaving the room, avoiding increased physiological regulatory burden on the body. This is especially beneficial for the elderly and children, whose thermoregulation abilities are weaker, preventing colds and cardiovascular diseases and ensuring their health. Exiting the in / out mode also ensures that the air conditioner provides a suitable indoor environment when the user is not entering or leaving the room.
[0029] Example 1: An air conditioning control method based on indoor and outdoor temperature difference, comprising: When the first preset condition is triggered, the entry and exit mode is entered. The entry and exit 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 the preset temperature difference. As a preferred implementation of this application, entering the entry / exit mode includes: Real-time acquisition of indoor and outdoor temperatures; this is achieved through temperature sensors installed both indoors and outdoors. For example, existing air conditioners typically have temperature sensors installed both indoors and outdoors, allowing the acquisition of indoor and outdoor temperatures based on these sensors. Alternatively, indoor temperatures can be acquired via network communication (through communication with devices equipped with indoor temperature sensors) and outdoor temperatures (by obtaining weather forecasts).
[0030] When the absolute value of the temperature difference between the indoor and outdoor temperatures is greater than a preset temperature difference, the operating status of the air conditioner is determined based on the indoor and outdoor temperatures. When the absolute value of the temperature difference between the indoor and outdoor temperatures is greater than the preset temperature difference, the indoor and outdoor temperature difference is relatively large, and the physiological regulatory burden on users is greater when entering and leaving the house. Therefore, it is necessary to reduce the indoor and outdoor temperature difference at this time.
[0031] Specifically: determining the operating status of the air conditioner based on the indoor temperature and the outdoor temperature includes: When the indoor temperature is higher than the outdoor temperature, the air conditioner is controlled to operate in cooling mode. Since the indoor temperature is high and the outdoor temperature is low, the air conditioner operates in cooling mode to lower the indoor temperature, so that the absolute value of the temperature difference between the indoor and outdoor temperatures is less than a preset temperature difference. The specific operation of the air conditioner in this application does not improve upon existing technology and will not be described in detail here.
[0032] When the indoor temperature is lower than the outdoor temperature, the air conditioner is controlled to operate in heating mode. When the indoor temperature is lower than the outdoor temperature, the indoor temperature is low and the outdoor temperature is high; therefore, the air conditioner operates in heating mode to raise the indoor temperature so that the absolute value of the temperature difference between the indoor and outdoor temperatures is less than a preset temperature difference. The implementation of this application does not improve upon existing technology in terms of how the air conditioner operates in heating mode, and will not be described in detail here.
[0033] Furthermore, it also includes: After the air conditioner has been running in a defined operating state for a preset duration, the first indoor temperature change rate at the current compressor frequency is obtained, and the 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, where the remaining time is the time difference between the time of leaving or entering the room and the current time. It should be noted that the preset temperature difference here is the same as the preset temperature difference where the absolute value of the temperature difference between the controlled indoor temperature and the real-time outdoor temperature in the entry mode is less than the preset temperature difference.
[0034] The air conditioner needs to operate in a predetermined operating state for a preset duration to ensure that the calculated first indoor temperature change rate is the indoor temperature change rate at the current compressor frequency. This is because if the first indoor temperature change rate is calculated directly, the compressor may not have run in the corresponding operating state yet, or although it has run in the corresponding operating state, its cooling or heating capacity may not be stable since it has just started.
[0035] The first indoor temperature change rate can be calculated every preset period. For example, if the preset period is 60 seconds, the indoor temperature obtained 60 seconds ago is t1, and the current indoor temperature is t2. The first indoor temperature change rate is calculated as (t2-t1) / 60. The second temperature change rate is calculated to ensure a more stable indoor temperature change. Therefore, it uses the difference between the current temperature difference and the preset temperature difference to ensure a relatively uniform indoor temperature change rate over the remaining time, preventing large fluctuations in indoor temperature and providing a better user experience.
[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 too fast at the current compressor frequency, which will cause fluctuations in the indoor temperature. Therefore, the compressor frequency should be reduced. When reducing the compressor frequency, the first preset frequency value can be decreased at preset intervals. Conversely, 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 too slow at the current compressor frequency, and ultimately, the absolute value of the temperature difference between the indoor temperature and the real-time outdoor temperature cannot be less than a preset temperature difference. Therefore, the compressor frequency should be increased. When increasing the compressor frequency, the second preset frequency value can be increased at preset intervals. The first and second preset frequency values can be set according to actual needs and can be equal.
[0038] In one embodiment, the first preset condition is triggered when the time difference between the time of leaving or entering the house and the current time is less than a first preset time difference.
[0039] The solution in this application embodiment involves pre-emptive control before the user leaves or enters the house. Since the temperature difference between indoors and outdoors is generally significant when using air conditioning, immediate control would result in large indoor temperature fluctuations, negatively impacting user experience. It's equivalent to the user moving directly from outdoors to indoors or vice versa, placing a considerable physiological burden on them. Furthermore, air conditioning temperature adjustment has a certain lag, making immediate adjustment practically impossible. Therefore, advance adjustment is generally necessary. For example, entering / exiting mode 10 minutes before entering or leaving the house.
[0040] In another embodiment, if the distance between the user and the house is detected to be less than a preset distance, the first preset condition is triggered. Specifically, GPS or Bluetooth positioning is integrated into the air conditioning control system. When the user leaves the house by a certain distance (e.g., 500 meters) or approaches the house by a certain distance, an entry / exit mode is activated. The user only needs to set the indoor / outdoor temperature difference, eliminating the need to manually set the entry / exit time, thus achieving a more intelligent temperature control experience.
[0041] It should be noted that the above two embodiments can be used individually or in combination; that is, when either condition is detected, the first preset condition is determined to be triggered.
[0042] In one embodiment, the entry and exit times are set by the user. That is, this application requires the user to set the entry and exit times, as well as the indoor and outdoor temperature difference (preset temperature difference value).
[0043] In another embodiment, it also includes: The system retrieves the weather, temperature, and current date for a preset time period. The preset time period divides a 24-hour day into multiple preset time segments, such as half-hour segments. The purpose of these preset time periods is to predict entry and exit times within certain time segments, such as 7-8 AM and 5-6 PM (specific times may vary depending on user settings or historical data analysis). Other times, such as 11 PM to 6 AM the next day, do not require prediction. Generally, a prediction is made only once per time segment. To ensure sufficient time, a prediction is typically made as soon as the preset time period begins. However, to handle unforeseen circumstances, such as rain starting after the prediction (even if it wasn't predicted), users may leave earlier or enter later. Therefore, in this embodiment, if the weather changes within the same target preset time period, a second prediction is made. The target preset time period is the time segment for which prediction is required.
[0044] Input the current time, weather, temperature, and date into a pre-built prediction model to obtain the predicted entry time or exit time.
[0045] In this embodiment, a prediction model is pre-built, and the entry and exit times are directly output based on the model's predictions. For example, an initial neural network model is constructed, consisting of an input layer, a connection layer, and an output layer. The input layer includes four neurons, which take the current time, weather, temperature, and current date as inputs. The connection layer has three layers, with 8, 10, and 8 neurons in each layer, respectively. The parameters within the connection layers are randomly set (adjusted through subsequent training). The output layer contains only one neuron. The training samples are historical data, including the specific time of each entry or exit, the current date, and the weather, temperature, and current date for that time period. Accuracy is used as the loss function. Historical data can be obtained in various ways, such as through camera detection of entry / exit, network access to obtain weather conditions and the current date, or a temperature sensor to obtain temperature information.
[0046] It's important to clarify that "weather" refers to the weather within a preset time period, primarily categorized into two types: severe weather and normal weather. Severe weather includes moderate to heavy rain, moderate to heavy snow, heavy fog, and strong winds. Normal weather encompasses all weather conditions other than severe weather. During training, historical weather data is labeled using these two categories. While it's possible to further categorize each type of weather, the more categories, the less likely the model will converge. The reason for using weather as input is that severe weather typically affects users' entry and exit plans, causing their entry and exit times to differ from usual.
[0047] The current time is used as input to predict whether the person is entering or leaving the room.
[0048] The main reason for using temperature is to differentiate between winter and summer. Users enter and leave their homes at different times in different seasons.
[0049] The use of dates is mainly to distinguish between weekdays, regular weekends, and public holidays. Therefore, the training set needs to indicate whether the date is a weekday, regular weekend, or public holiday.
[0050] In addition, during training, to prevent overfitting, the parameters of one neuron in the randomized connection layer are set to 0 for each training session.
[0051] In addition, in one embodiment, the first preset time difference value is a fixed value set by the user.
[0052] In another embodiment, the first preset time difference is a dynamic value. While a fixed duration ensures consistent entry and exit times, the temperature difference between the indoor and target outdoor temperatures may differ significantly. A large difference could cause the indoor temperature to change too rapidly per unit time, negatively impacting user experience. Although this can be adjusted via compressor frequency, in extreme cases, it might exceed the compressor's adjustment capabilities, such as when the compressor frequency has reached its limit. Therefore, adjusting the first preset time difference can adjust the entry and exit time, potentially increasing the time in extreme situations.
[0053] Specifically as follows: When the time difference between the departure 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.
[0054] The first preset time difference is determined based on the absolute value of the temperature difference; the larger the absolute value of the temperature difference, the larger the first preset time difference.
[0055] If a second preset condition is triggered while in the enter / exit mode, the enter / exit mode will be exited.
[0056] When the current time is the time to leave or the time to enter, the second preset condition is determined to be triggered; And / or, after detecting that a user enters or leaves the room, determine that a second preset condition is triggered.
[0057] In addition, the outdoor temperature is obtained when the sleep mode is running; During a first preset duration after the start of the sleep mode, the temperature difference between the indoor temperature and the outdoor temperature is controlled to be a first preset temperature difference value; when the sleep mode ends after a second preset duration, the temperature difference between the indoor temperature and the outdoor temperature is controlled to be a second preset temperature difference value, wherein the first preset temperature difference value is greater than the second preset temperature difference value.
[0058] It should be noted that any process or method description in the flowchart or otherwise described herein can be understood as representing a module, segment, or portion of code comprising one or more executable instructions for implementing a particular logical function or process, and the scope of the preferred embodiments of this application includes additional implementations in which functions may be performed not in the order shown or discussed, including substantially simultaneously or in reverse order according to the functions involved, as should be understood by those skilled in the art to which the embodiments of this application pertain.
[0059] Furthermore, in the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[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 means that the user expects the indoor temperature to be lower than the outdoor ambient temperature, and the air conditioner will operate in "cooling" mode; if the user sets the indoor-outdoor temperature difference TΔ>0 ℃, it means that the user expects the indoor temperature to be higher than the outdoor ambient temperature, and the air conditioner will operate in "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' based on the outdoor ambient temperature To and the expected indoor-outdoor temperature difference TΔ, which is then rounded up and used as the target indoor temperature for air conditioning operation; 4. After the user sets the "entry / exit mode", the control module starts timing. If the remaining time t' of the current "entry / exit mode" is not 0, the adjustment program will run in a loop. The system continuously monitors the changes in indoor and outdoor temperatures and dynamically adjusts the air conditioning operating parameters to ensure that the temperature difference is controlled within the range set by the user. That is, 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 and outdoor temperature difference in the expected time and the indoor temperature change is relatively average.
[0064] 5. If the remaining time t' = 0, exit "Entry / Exit Mode". The air conditioner's status after exiting can be determined based on its status when "Entry / Exit Mode" was set. If it was set to "On", the user may need to leave, and the air conditioner will automatically turn off after exiting "Entry / Exit Mode". If it was set to "Off", the user may need to enter, and the air conditioner will continue to operate according to the historical settings of the corresponding mode after exiting "Entry / Exit Mode".
[0065] Furthermore, when a user activates the indoor-outdoor temperature difference adjustment sleep mode, the indoor temperature dynamically responds to changes in the outdoor temperature in real time. During the nighttime sleep period, the indoor temperature is maintained at a lower set value to promote sleep; during the morning wake-up period, the indoor temperature is raised to a higher set value to promote wake-up. Specifically, this sleep mode gradually lowers the indoor temperature after the user falls asleep and gradually raises 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] Example 2: An air conditioning control method based on indoor and outdoor temperature difference, comprising: When the first preset condition is triggered, the system enters the entry / exit mode, which 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 this application, entering the entry / exit mode includes: Obtain the predicted outdoor temperature at the time of entry or exit; that is, predict the outdoor temperature as the outdoor temperature when the user enters and exits.
[0068] The absolute value of the temperature difference between the indoor temperature and the predicted outdoor temperature when controlling the entry or exit time is less than the preset temperature difference value.
[0069] The outdoor temperature prediction is obtained from weather forecasts or from a trained temperature prediction model; this application does not impose specific limitations on this method. For example, a meteorological data interface is introduced into the air conditioning control system to obtain outdoor temperature prediction data for the next 24 hours. The control module combines historical indoor-outdoor temperature difference trends with future weather changes to adjust the indoor temperature in advance to cope with possible extreme weather changes. For instance, if meteorological data shows that outdoor temperature may change abruptly, using the real-time outdoor ambient temperature would cause the expected indoor temperature to also change abruptly; however, using only the predicted outdoor temperature corresponding to the time of departure can avoid this temperature change.
[0070] In one embodiment, the first preset condition is triggered when the time difference between the time of leaving or entering the house and the current time is less than a first preset time difference.
[0071] The solution in this application embodiment involves pre-emptive control before the user leaves or enters the house. Since the temperature difference between indoors and outdoors is generally significant when using air conditioning, immediate control would result in large indoor temperature fluctuations, negatively impacting user experience. It's equivalent to the user moving directly from outdoors to indoors or vice versa, placing a considerable physiological burden on them. Furthermore, air conditioning temperature adjustment has a certain lag, making immediate adjustment practically impossible. Therefore, advance adjustment is generally necessary. For example, entering / exiting mode 10 minutes before entering or leaving the house.
[0072] In another embodiment, if the distance between the user and the house is detected to be less than a preset distance, the first preset condition is triggered. Specifically, GPS or Bluetooth positioning is integrated into the air conditioning control system. When the user leaves the house by a certain distance (e.g., 500 meters) or approaches the house by a certain distance, an entry / exit mode is activated. The user only needs to set the indoor / outdoor temperature difference, eliminating the need to manually set the entry / exit time, thus achieving a more intelligent temperature control experience.
[0073] It should be noted that the above two embodiments can be used individually or in combination; that is, when either condition is detected, the first preset condition is determined to be triggered.
[0074] In one embodiment, the entry and exit times are set by the user. That is, this application requires the user to set the entry and exit times, as well as the indoor and outdoor temperature difference (preset temperature difference value).
[0075] In another embodiment, it also includes: The system retrieves the weather, temperature, and current date for a preset time period. The preset time period divides a 24-hour day into multiple preset time segments, such as half-hour segments. The purpose of these preset time periods is to predict entry and exit times within certain time segments, such as 7-8 AM and 5-6 PM (specific times may vary depending on user settings or historical data analysis). Other times, such as 11 PM to 6 AM the next day, do not require prediction. Generally, a prediction is made only once per time segment. To ensure sufficient time, a prediction is typically made as soon as the preset time period begins. However, to handle unforeseen circumstances, such as rain starting after the prediction (even if it wasn't predicted), users may leave earlier or enter later. Therefore, in this embodiment, if the weather changes within the same target preset time period, a second prediction is made. The target preset time period is the time segment for which prediction is required.
[0076] Input the current time, weather, temperature, and date into a pre-built prediction model to obtain the predicted entry time or exit time.
[0077] In this embodiment, a prediction model is pre-built, and the entry and exit times are directly output based on the model's predictions. For example, an initial neural network model is constructed, consisting of an input layer, a connection layer, and an output layer. The input layer includes four neurons, which take the current time, weather, temperature, and current date as inputs. The connection layer has three layers, with 8, 10, and 8 neurons in each layer, respectively. The parameters within the connection layers are randomly set (adjusted through subsequent training). The output layer contains only one neuron. The training samples are historical data, including the specific time of each entry or exit, the current date, and the weather, temperature, and current date for that time period. Accuracy is used as the loss function. Historical data can be obtained in various ways, such as through camera detection of entry / exit, network access to obtain weather conditions and the current date, or a temperature sensor to obtain temperature information.
[0078] It's important to clarify that "weather" refers to the weather within a preset time period, primarily categorized into two types: severe weather and normal weather. Severe weather includes moderate to heavy rain, moderate to heavy snow, heavy fog, and strong winds. Normal weather encompasses all weather conditions other than severe weather. During training, historical weather data is labeled using these two categories. While it's possible to further categorize each type of weather, the more categories, the less likely the model will converge. The reason for using weather as input is that severe weather typically affects users' entry and exit plans, causing their entry and exit times to differ from usual.
[0079] The current time is used as input to predict whether the person is entering or leaving the room.
[0080] The main reason for using temperature is to differentiate between winter and summer. Users enter and leave their homes at different times in different seasons.
[0081] The use of dates is mainly to distinguish between weekdays, regular weekends, and public holidays. Therefore, the training set needs to indicate whether the date is a weekday, regular weekend, or public holiday.
[0082] In addition, during training, to prevent overfitting, the parameters of one neuron in the randomized connection layer are set to 0 for each training session.
[0083] In addition, in one embodiment, the first preset time difference value is a fixed value set by the user.
[0084] In another embodiment, the first preset time difference is a dynamic value. While a fixed duration ensures consistent entry and exit times, the temperature difference between the indoor and target outdoor temperatures may differ significantly. A large difference could cause the indoor temperature to change too rapidly per unit time, negatively impacting user experience. Although this can be adjusted via compressor frequency, in extreme cases, it might exceed the compressor's adjustment capabilities, such as when the compressor frequency has reached its limit. Therefore, adjusting the first preset time difference can adjust the entry and exit time, potentially increasing the time in extreme situations.
[0085] Specifically as follows: When the time difference between the departure 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; the larger the absolute value of the temperature difference, the larger the first preset time difference.
[0087] If a second preset condition is triggered while in the enter / exit mode, the enter / exit mode will be exited.
[0088] When the current time is the time to leave or the time to enter, the second preset condition is determined to be triggered; And / or, after detecting that a user enters or leaves the room, determine that a second preset condition is triggered.
[0089] In addition, the outdoor temperature is obtained when the sleep mode is running; During a first preset duration after the start of the sleep mode, the temperature difference between the indoor temperature and the outdoor temperature is controlled to be a first preset temperature difference value; when the sleep mode ends after a second preset duration, the temperature difference between the indoor temperature and the outdoor temperature is controlled to be a second preset temperature difference value, wherein the first preset temperature difference value is greater than the second preset temperature difference value.

[0092] 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.

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.
