Technical Field

[0001] The present application relates to the field of control management technology, and in particular to a central air-conditioning control method, control system, storage medium and program product. Background Art

[0002] With the improvement of the quality of life, people's requirements for living and working environment are also increasing. Central air conditioners have powerful adjustment capabilities and can accurately control the indoor temperature and humidity to provide a more comfortable living environment. Therefore, in modern architectural design and daily life, central air conditioners have become an indispensable part. However, with the increasingly severe global energy crisis and the general enhancement of environmental awareness, how to reduce the energy consumption during the use of central air conditioners while ensuring a stable and comfortable indoor temperature has become a technical problem that needs to be solved urgently.

[0003] The operation of traditional central air conditioners often relies on fixed temperature settings and simple switch controls. Although this control method is simple and direct, it lacks flexibility and is difficult to automatically adjust according to actual changes in the indoor and outdoor environment, which may lead to energy waste. Summary of the invention

[0004] In order to reduce the energy consumption during the use of central air conditioning while ensuring a stable and comfortable indoor temperature, the present application provides a central air conditioning control method, control system, storage medium and program product.

[0005] In a first aspect, the present application provides a central air conditioning control method, which adopts the following technical solution: A central air conditioning control method, comprising: Obtain indoor environmental parameters and outdoor environmental parameters; Determining a floating range of the indoor temperature based on the indoor environmental parameter, the outdoor environmental parameter, a set temperature, and an air-conditioning operation mode, wherein the air-conditioning operation mode includes a heating mode and a cooling mode; The operation of the central air conditioner is controlled based on the set temperature, and the operation power of the central air conditioner is adjusted based on the floating range corresponding to the air conditioner operation mode and the real-time indoor temperature.

[0006] By adopting the above technical scheme, a reasonable temperature fluctuation range is set by comprehensively considering indoor environmental parameters and outdoor environmental parameters, and the operating power of the central air-conditioning is regulated based on this, rather than arbitrarily setting a temperature fluctuation range, so as to ensure that the central air-conditioning is more flexible and efficient in responding to external changes, and there is no need to frequently start and adjust the operating power to maintain the set temperature. Through this temperature fluctuation range, a certain fluctuation in indoor temperature can be allowed while ensuring that the indoor temperature is comfortable and stable, which can avoid the central air-conditioning from being in a high operating power operating state all the time, thereby facilitating the reduction of overheating or overcooling of the central air-conditioning, and further facilitating the reduction of energy consumption generated during the use of the central air-conditioning while ensuring that the indoor temperature is stable and comfortable.

[0007] In a possible implementation, adjusting the operating power of the central air conditioner based on the floating range corresponding to the air conditioner operating mode and the real-time indoor temperature includes: In the heating mode, when the real-time indoor temperature is not lower than the set temperature, the original operating power of the central air conditioner is adjusted to obtain a first operating power, and the central air conditioner is controlled to perform heating based on the first operating power; when the real-time indoor temperature exceeds the floating range corresponding to the heating mode, the central air conditioner is controlled to perform heating based on the original operating power, and the first operating power is lower than the original operating power; In cooling mode, when the real-time indoor temperature is not higher than the set temperature, the original operating power of the central air conditioner is adjusted to obtain a second operating power, and the central air conditioner is controlled to perform cooling based on the second operating power; when the real-time indoor temperature exceeds the floating range corresponding to the cooling mode, the central air conditioner is controlled to perform cooling based on the original operating power, and the second operating power is lower than the original operating power.

[0008] By adopting the above technical solution, two power control methods under different air-conditioning operation modes are provided, so that when the real-time indoor temperature reaches the set temperature, the air-conditioning operation power can be timely adjusted based on the floating range corresponding to the heating mode or the cooling mode, so as to avoid overheating or overcooling caused by continuing to operate at high operation power, thereby reducing the energy consumption of the central air-conditioning during operation.

[0009] In one possible implementation, the method further includes: Determining a predicted temperature change rate based on the indoor environmental parameter and the outdoor environmental parameter; During the heating process of controlling the central air conditioner based on the first operating power, recording the temperature change rate; When the temperature change rate is higher than the predicted temperature change rate, obtaining the real-time environmental parameters corresponding to the current moment, and determining the abnormality type based on the real-time environmental parameters, the abnormality type including indoor abnormality and outdoor abnormality; Based on the abnormality type, the set temperature and the floating range are adjusted.

[0010] By adopting the above technical solution, the predicted temperature change rate is determined by comprehensively analyzing the indoor environmental parameters and the outdoor environmental parameters, and this is used to judge whether there is an abnormal cooling situation, rather than judging whether there is an abnormal cooling situation based on a preset fixed value, thereby facilitating the improvement of the accuracy of the abnormal judgment results, and then adjusting the floating range of the indoor temperature in a targeted manner according to the specific abnormal type, so as to effectively deal with the abnormal cooling situation, thereby ensuring the stability and comfort of the indoor temperature. At the same time, by adjusting the floating range of the indoor temperature in a targeted manner, it is helpful to reduce unnecessary energy consumption of the central air-conditioning when there is an abnormal cooling of the indoor temperature.

[0011] In a possible implementation, when the abnormality type is an indoor abnormality, adjusting the set temperature and the floating range based on the abnormality type includes: Identify preset abnormal features contained in the indoor image, and determine whether there is a moving target in the abnormal associated area corresponding to the preset abnormal features; If yes, then record the moving frequency and the duration of stay of the moving target in the abnormal associated area within a preset time period; Determine the abnormality type corresponding to the preset abnormality feature based on the movement frequency and the stay duration, wherein the abnormality type is an active abnormality type and a passive abnormality type; When the abnormality type is a passive abnormality type, after eliminating the preset abnormality feature, the set temperature and the floating range are adjusted.

[0012] By adopting the above technical solution, by identifying the preset abnormal features contained in the indoor image, it is convenient to promptly determine the cause of the abnormal drop in indoor temperature. In addition, by analyzing the movement frequency and residence time of the mobile target in the abnormal associated area, it is convenient to automatically determine the abnormal type of the preset abnormal feature in a short time, and based on the abnormal type, a targeted elimination strategy can be formulated, thereby reducing the energy waste caused by the preset abnormal features, and also facilitating the timely restoration of the indoor temperature to a stable set temperature.

[0013] In a possible implementation, when the abnormality type is a passive abnormality type, the method of eliminating the preset abnormality feature includes: Determining prompt information based on the preset abnormal feature and the abnormal associated area; Based on the abnormal associated area, determining a target person and a target area where the target person is located from the indoor image; Acquiring an ambient volume, and determining a feedback volume based on the ambient volume; The prompt information is fed back to the feedback device in the target area based on the feedback volume to prompt the target person to eliminate the preset abnormal features contained in the abnormal associated area.

[0014] By adopting the above technical solution, the prompt information determined by the preset abnormal features and abnormal associated areas can accurately inform the relevant target personnel of the abnormal features and their positions that need to be eliminated, so that the relevant target personnel can quickly locate and handle the abnormalities, reducing the time required for finding and confirming the abnormal features. In addition, by determining the target person and the target area where he is located from the indoor image through the abnormal associated area, it can ensure that the prompt information is accurately conveyed to the relevant target personnel who are relatively close to the abnormal associated area, so as to further improve the abnormal response speed. Finally, the volume of the prompt information is adjusted based on the actual volume of the current environment to ensure that the target person can clearly hear the prompt information.

[0015] In one possible implementation, the method further includes: Determining a direct blowing area based on a set position of the central air conditioner and an original blowing mode; When the direct blowing area contains a human feature and the human feature is in a stationary state, identifying the stationary position of the human feature in the direct blowing area; Determine a non-blowing area based on the static position, the set temperature, and the current operating power of the central air conditioner; The original blowing mode of the central air conditioner is adjusted based on the non-blowing area.

[0016] By adopting the above technical solution, when it is detected that a stationary person is included in the direct blowing area, the non-blowing area is promptly determined, and the original blowing mode of the central air-conditioning is automatically adjusted according to the non-blowing area, so as to avoid the stationary person being in a direct blowing state for a long time, thereby facilitating improving the comfort of the stationary person.

[0017] In a second aspect, the present application provides a control system, which adopts the following technical solution: A control system, the control system comprising: at least one processor; Memory; At least one application, wherein the at least one application is stored in a memory and configured to be executed by at least one processor, and the at least one application is configured to: execute the above-mentioned central air conditioning control method.

[0018] In a third aspect, the present application provides a computer-readable storage medium, which adopts the following technical solution: A computer-readable storage medium includes: a computer program that can be loaded by a processor and execute the central air-conditioning control method.

[0019] In a fourth aspect, the present application provides a computer program product, which adopts the following technical solution: A computer program product includes a computer program, and when the computer program is executed by a processor, the central air-conditioning control method is implemented.

[0020] In summary, the present application includes at least one of the following beneficial technical effects: By comprehensively considering indoor and outdoor environmental parameters to set a reasonable temperature fluctuation range, and adjusting the operating power of the central air-conditioning based on this, instead of arbitrarily setting a temperature fluctuation range, it is convenient to ensure that the central air-conditioning is more flexible and efficient in responding to external changes, and there is no need to frequently start and adjust the operating power to maintain the set temperature. Through this temperature fluctuation range, the indoor temperature is allowed to fluctuate to a certain extent while ensuring the indoor temperature is comfortable and stable, which can avoid the central air-conditioning being in a high operating power operating state all the time, thereby reducing the situation of overheating or overcooling of the central air-conditioning, and then reducing the energy consumption generated during the use of the central air-conditioning while ensuring the indoor temperature is stable and comfortable.

[0021] By identifying the preset abnormal features contained in the indoor image, it is convenient to promptly determine the cause of the abnormal drop in indoor temperature. In addition, by analyzing the movement frequency and residence time of the mobile target in the abnormal associated area, it is convenient to automatically determine the abnormal type of the preset abnormal feature in a short time, and a targeted elimination strategy can be formulated based on the abnormal type, thereby reducing the energy waste caused by the preset abnormal features and promptly restoring the indoor temperature to a stable set temperature.

DETAILED DESCRIPTION

[0023] The following is combined with Figures 1 to 3 This application is described in further detail.

[0024] After reading this specification, those skilled in the art may make modifications to this embodiment without any creative contribution as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of this application.

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] It should be noted that in the optional embodiments of the present application, the object information and other related data involved, when the embodiments in the present application are applied to specific products or technologies, need to obtain the permission or consent of the object, and the collection, use and processing of the relevant data need to comply with the relevant laws, regulations and standards of the relevant countries and regions.

[0027] Specifically, the embodiment of the present application provides a central air conditioning control method, which is executed by a control system, and the control system can be a server or a terminal device, wherein the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto.

[0028] refer to Figure 1 , Figure 1 : is a flow chart of a central air conditioning control method in an embodiment of the present application, the method comprises steps S110 to S130, wherein: Step S110: Acquire indoor environmental parameters and outdoor environmental parameters.

[0029] Specifically, indoor environmental parameters may include indoor humidity, indoor ventilation, enclosure structure performance, equipment heat dissipation, etc., among which indoor humidity is one of the important factors affecting indoor and outdoor heat exchange. In a high humidity environment, the water vapor content in the indoor air is high, which may slow down the heat transfer rate; indoor ventilation is another important factor affecting indoor and outdoor heat exchange. Good ventilation can accelerate indoor and outdoor air exchange, reduce indoor temperature, and take away indoor heat and moisture. On the contrary, poor ventilation may cause indoor temperature to rise, increasing the difficulty of indoor and outdoor heat exchange; walls and roofs are the main channels for indoor and outdoor heat exchange. The better the thermal insulation performance of the walls and the thermal insulation performance of the roof, the less indoor and outdoor heat exchange; various indoor electrical appliances such as televisions, computers, refrigerators, air conditioners, lighting equipment, etc., will also generate heat during operation, thereby affecting indoor and outdoor heat exchange. Among the indoor environmental parameters, the indoor humidity can be collected by a humidity sensor installed indoors and uploaded to the control system, the indoor ventilation can be collected by an air quality detection device installed indoors and uploaded to the control system, the enclosure structure performance can be uploaded to the control system in advance by the user, and the equipment heat dissipation can be collected by a temperature sensor installed indoors and uploaded to the control system. The method of obtaining indoor environmental parameters is not specifically limited in the embodiments of the present application.

[0030] Outdoor environmental parameters may include external temperature, wind speed, wind direction, weather, etc., among which external temperature is one of the main factors affecting indoor temperature. An increase or decrease in outdoor temperature may affect indoor temperature through enclosing structures such as walls, doors and windows. The effects of wind speed and wind direction on indoor temperature are mainly reflected in ventilation and heat exchange. Stronger wind speeds may accelerate indoor and outdoor heat exchange, thereby affecting indoor temperature. In addition, weather conditions such as rain, snow, and fog will also affect indoor and outdoor temperatures.

[0031] Step S120: Determine the floating range of the indoor temperature based on the indoor environmental parameters, the outdoor environmental parameters, the set temperature and the air-conditioning operation mode, where the air-conditioning operation mode includes a heating mode and a cooling mode.

[0032] Specifically, the set temperature can be set by the user when turning on the central air conditioner, and the air conditioner operation mode can also be set by the user when turning on the central air conditioner. The air conditioner operation mode includes heating mode and cooling mode. When the set temperature is constant, different air conditioner operation modes correspond to different floating ranges. When the air conditioner operation mode is heating mode, the central air conditioner blows hot air to increase the indoor temperature. Once the central air conditioner is turned off or the operating power is reduced, the indoor temperature will drop. Therefore, the floating range corresponding to the heating mode is generally lower than the set temperature. For example, when the set temperature is 23 degrees, the floating range of the indoor temperature may be 21 degrees-23 degrees; and when the air conditioner operation mode is cooling mode, the central air conditioner blows cold air to reduce the indoor temperature. Once the central air conditioner is turned off or the operating power is reduced, the indoor temperature will rise. Therefore, the floating range corresponding to the cooling mode is generally higher than the set temperature. For example, when the set temperature is 23 degrees, the floating range of the indoor temperature may be 23 degrees-26 degrees.

[0033] In heating mode, the floating range formula of indoor temperature can be: Floating range lower limit = set temperature - Δtheat1; Upper limit of floating range = set temperature; Among them, Δtheat1 is the temperature difference calculated based on the indoor environmental parameters and the outdoor environmental parameters.

[0034] Ideally, when the set temperature is 23 degrees, the indoor temperature will also rise to 23 degrees. However, due to the influence of indoor and outdoor environmental parameters, when the indoor temperature reaches the set temperature of 23 degrees, it may be difficult to maintain it at 23 degrees for a long time. If you need to ensure that the indoor temperature can be maintained at 23 degrees for a long time, you may need to keep the central air conditioner in a high-power working state. However, if the central air conditioner is in a high-power working state for a long time, it may affect its service life. Therefore, in order to extend the service life of the central air conditioner and not affect the user's experience, the user will generally set an acceptable minimum temperature, such as 18 degrees. That is, under the joint influence of indoor and outdoor environmental parameters, even if the operating power of the central air conditioner is reduced, the indoor temperature cannot drop below 18 degrees. Since different indoor environmental parameters and outdoor environmental parameters will affect the temperature drop, it is necessary to determine Δtheat1 based on the indoor environmental parameters and the outdoor environmental parameters. The indoor environmental parameters and the outdoor environmental parameters can be input into a trained regression model to obtain the corresponding Δtheat1, wherein the regression model can be trained by the empirical temperature difference corresponding to different combinations of indoor and outdoor environmental parameters. The method of obtaining Δtheat1 is not specifically limited in the embodiments of the present application.

[0035] Similarly, in cooling mode, the floating range formula of indoor temperature can be: Floating range lower limit = set temperature; Upper limit of floating range = set temperature + Δtheat2; Among them, Δtheat2 is the temperature difference calculated based on the indoor environmental parameters and the outdoor environmental parameters.

[0036] The method for determining Δtheat2 may refer to the method for determining Δtheat1 in the above embodiment, which will not be described in detail here.

[0037] Step S130: Control the operation of the central air conditioner based on the set temperature, and adjust the operating power of the central air conditioner based on the floating range corresponding to the air conditioner operation mode and the real-time indoor temperature.

[0038] Specifically, in the initial stage of heating or cooling, the central air conditioner can be controlled to heat or cool according to the set temperature and original operating power. After the indoor temperature rises or drops to the set temperature, the operating power of the central air conditioner can be adjusted based on the floating range corresponding to the heating or cooling model, that is, to avoid the central air conditioner always working at a high operating power. The specific process may include: In the heating mode, when the real-time indoor temperature is not lower than the set temperature, the original operating power of the central air conditioner is adjusted to obtain the first operating power, and the central air conditioner is controlled to perform heating based on the first operating power. When the real-time indoor temperature exceeds the floating range corresponding to the heating mode, the central air conditioner is controlled to perform heating based on the original operating power, and the first operating power is lower than the original operating power.

[0039] Specifically, the indoor temperature can be monitored in real time by a temperature sensor arranged indoors. When the real-time indoor temperature is not lower than the set temperature, the original operating load of the central air conditioner can be appropriately reduced to reduce the workload of the central air conditioner. At this time, the real-time indoor temperature may be lower than the set temperature. The first operating power is lower than the original operating power. The specific first operating power is not specifically limited in the embodiment of the present application, as long as the first operating power is lower than the original operating power. Since indoor environmental parameters and outdoor environmental parameters may affect heat exchange, when the central air conditioner is working at the first operating power, it is still necessary to monitor the indoor temperature in real time. Once the real-time indoor temperature is found to exceed the corresponding floating range, for example, when the floating range is 21 degrees to 23 degrees, but based on the first operating power during operation, the real-time indoor temperature becomes 20 degrees. At this time, the real-time indoor temperature has exceeded the corresponding floating range, and the operating power of the central air conditioner needs to be restored as soon as possible to ensure the user experience.

[0040] In cooling mode, when the real-time indoor temperature is not higher than the set temperature, the original operating power of the central air-conditioner is adjusted to obtain the second operating power, and the central air-conditioner is controlled to perform cooling based on the second operating power. When the real-time indoor temperature exceeds the floating range corresponding to the cooling mode, the central air-conditioner is controlled to perform cooling based on the original operating power, and the second operating power is lower than the original operating power.

[0041] Specifically, the second operating power is lower than the original operating power. The specific second operating power is not specifically limited in the embodiment of the present application, as long as the second operating power is lower than the original operating power. Once it is found that the real-time indoor temperature exceeds the corresponding floating range, for example, when the floating range is 23 degrees to 26 degrees, but based on the second operating power working period, the real-time indoor temperature becomes 27 degrees, at this time, the real-time indoor temperature has exceeded the corresponding floating range, and the operating power of the central air conditioner needs to be restored as soon as possible to ensure the user experience.

[0042] Two power control methods are provided under different air-conditioning operation modes. When the real-time indoor temperature reaches the set temperature, the air-conditioning operation power can be timely adjusted based on the floating range corresponding to the heating mode or cooling mode to avoid overheating or overcooling caused by continuing to operate at high operation power, thereby reducing the energy consumption of the central air-conditioning during operation.

[0043] For the embodiment of the present application, a reasonable temperature fluctuation range is set by comprehensively considering indoor environmental parameters and outdoor environmental parameters, and the operating power of the central air-conditioning is regulated based on this, rather than arbitrarily setting a temperature fluctuation range. This ensures that the central air-conditioning is more flexible and efficient in responding to external changes, and there is no need to frequently start and adjust the operating power to maintain the set temperature. Through this temperature fluctuation range, a certain fluctuation in indoor temperature can be allowed while ensuring that the indoor temperature is comfortable and stable, which can prevent the central air-conditioning from always being in a high operating power operating state, thereby facilitating the reduction of overheating or overcooling of the central air-conditioning, and further facilitating the reduction of energy consumption generated during the use of the central air-conditioning while ensuring that the indoor temperature is stable and comfortable.

[0044] Furthermore, in the heating mode, if the first operating power is used, the indoor temperature may drop. Similarly, in the cooling mode, if the second operating power is used, the indoor temperature may rise. However, under the influence of indoor environmental parameters and outdoor environmental parameters, the rate of change of temperature drop or temperature rise may be affected. For the heating model, in order to effectively deal with abnormal temperature drop and ensure the stability and comfort of indoor temperature, the method provided in the embodiment of the present application also includes: Determine the predicted temperature change rate based on indoor environmental parameters and outdoor environmental parameters; record the temperature change rate during the heating process of the central air conditioner controlled based on the first operating power; when the temperature change rate is higher than the predicted temperature change rate, obtain the real-time environmental parameters corresponding to the current moment, and determine the abnormality type based on the real-time environmental parameters, the abnormality type includes indoor abnormality and outdoor abnormality; adjust the set temperature and floating range based on the abnormality type.

[0045] Specifically, the predicted temperature change rate corresponding to the indoor environmental parameters and the outdoor environmental parameters can be determined by a preset change rate mapping relationship, wherein the preset change rate mapping relationship is the correspondence between the combination of the indoor environmental parameters and the outdoor environmental parameters and the predicted temperature change rate, and the preset change rate mapping relationship can be determined by relevant staff based on historical experimental data and uploaded to the control system, and the specific content is not specifically limited in the embodiments of the present application. When the central air conditioner is in the heating process based on the first operating power, if the temperature change rate of the indoor temperature is not higher than the predicted temperature change rate, it can be determined that the indoor temperature is in a stable change state and there is no abnormal situation; if the temperature change rate of the indoor temperature is higher than the predicted temperature change rate, it can be determined that the indoor temperature is in an unstable change state, which is an abnormal situation.

[0046] When an abnormal situation is detected, the cause of the abnormal temperature drop can be determined by analyzing the real-time environmental parameters, which include real-time indoor images and real-time outdoor weather data. The preset feature recognition algorithm can be used to identify and determine whether the real-time indoor image contains the preset abnormal feature. If the real-time indoor image contains the preset abnormal feature, the abnormal type can be determined to be an indoor abnormality, wherein the preset abnormal feature can be a window gap, a door gap, etc. The specific preset abnormal feature is not specifically limited in the embodiment of the present application, and can be determined by relevant staff based on historical experimental data and uploaded to the control system. If the real-time outdoor weather data contains the preset abnormal weather feature, the abnormal type can be determined to be an outdoor abnormality, wherein the preset abnormal weather feature can be a heavy rainfall higher than the preset rainfall, a strong low temperature lower than the preset temperature value, a strong wind higher than the preset level, etc. The specific preset rainfall, preset temperature value and preset level can be determined by relevant staff based on historical experimental data and uploaded to the control system, and the specific value is not specifically limited in the embodiment of the present application.

[0047] Different abnormality types correspond to different adjustment strategies. When the abnormality type is outdoor abnormality, the set temperature and the floating range can be directly increased. For example, the original set temperature of 23 degrees can be increased to 25 degrees, and the Δtheat1 corresponding to the floating range can be reduced to 1 degree, that is, the floating range is 24 degrees-25 degrees to maintain the indoor temperature. The increase value and the reduction value of Δtheat1 are not specifically limited in the embodiment of the present application, as long as it is higher than the original set temperature and less than the original Δtheat1.

[0048] When the abnormality type is an indoor abnormality, the temperature can be directly increased and the floating range can be adjusted. However, in order to reduce unnecessary energy consumption of the central air conditioner when the indoor temperature drops abnormally, the specific process of adjusting the set temperature and the floating range based on the abnormality type may include steps S210 to S240. Figure 2 As shown: Step S210: Identify preset abnormal features contained in the indoor image, and determine whether there is a moving target in the abnormal associated area corresponding to the preset abnormal features.

[0049] Specifically, the abnormal association area is an indoor area containing preset abnormal features. Since different preset abnormal features have different effects on the drop in indoor temperature, it is necessary to first determine the target impact distance corresponding to the preset abnormal feature based on the preset abnormal feature and the preset impact distance mapping relationship, and then determine the abnormal association area based on the abnormal center point of the preset abnormal feature and the target impact distance, wherein the preset impact distance mapping relationship is the corresponding relationship between the preset abnormal feature and the target impact distance. Based on the face recognition algorithm, it can be identified and judged from the indoor image whether there is a moving target in the abnormal association area. When the abnormal association area contains a face feature, it can be determined that the area contains a moving target. In the embodiment of the present application, the moving target can be a moving person.

[0050] Step S220: If yes, the moving frequency and the staying time of the moving target in the abnormal associated area within the preset time period are recorded.

[0051] Specifically, when there is a moving target in the abnormal associated area, the appearance time of the moving target within the preset time period can be recorded, and the movement frequency and stay time can be determined based on this. The preset time period is a period of time after it is determined that the abnormal associated area contains the moving target. The duration corresponding to the preset time period can be 3 minutes or 5 minutes. The specific duration is not specifically limited in the embodiment of the present application.

[0052] Step S230: determining the abnormality type corresponding to the preset abnormality feature based on the movement frequency and the stay duration, where the abnormality type is an active abnormality type and a passive abnormality type.

[0053] Specifically, it is possible to determine whether the mobile target knows the preset abnormal features contained in the abnormal association area by analyzing the movement frequency and the length of stay. When the movement frequency is higher than the preset movement frequency, or the length of stay is higher than the preset length of stay, it indicates that the mobile target frequently passes through the abnormal association area, or stays in the abnormal association area for a long time. At this time, it can be predicted that the preset abnormal features appearing in the abnormal association area are known to the mobile target, or are actively caused by the mobile target. For example, the mobile target opens the window, and the corresponding abnormal type can be determined as an active abnormal type; when the movement frequency is not higher than the preset movement frequency, or the length of stay is not higher than the preset length of stay, it indicates that the mobile target occasionally passes through the abnormal association area, and does not stay in the abnormal association area for a long time. At this time, it can be predicted that the preset abnormal features appearing in the abnormal association area are unknown to the mobile target, or are passively caused, for example, the outdoor wind blows the window open, and the corresponding abnormal type can be determined as a passive abnormal type. When the abnormal type is an active abnormal type, the temperature can be directly increased and the floating range can be adjusted. The specific increase or adjustment method can refer to the operation method when the abnormal type is an outdoor abnormality in the above embodiment, which will not be repeated here.

[0054] Step S240: When the abnormality type is a passive abnormality type, after eliminating the preset abnormal characteristics, the set temperature and floating range are adjusted.

[0055] Specifically, when the abnormality type is a passive abnormality type, it is necessary to eliminate the preset abnormal characteristics in the abnormal associated area first, and then adjust the set temperature and floating range. For example, after closing the doors and windows in the abnormal associated area, adjust the set temperature and floating range, so as to reduce the energy waste caused by the preset abnormal characteristics, and also facilitate timely restoration of the indoor temperature to a stable set temperature.

[0056] Based on the above embodiment, the set temperature and floating range in the cooling mode may also be adjusted accordingly, and the specific method will not be described in detail here.

[0057] Furthermore, in order to improve the abnormal response speed, when the abnormal type is a passive abnormal type, the method of eliminating the preset abnormal characteristics may specifically include: Prompt information is determined based on preset abnormal features and abnormal associated areas; based on the abnormal associated areas, a target person and a target area where the target person is located are determined from indoor images; the ambient volume is obtained, and a feedback volume is determined based on the ambient volume; based on the feedback volume, prompt information is fed back to a feedback device in the target area to prompt the target person to eliminate the preset abnormal features contained in the abnormal associated area.

[0058] Specifically, different preset abnormal features and abnormal associated areas correspond to different prompt information. For example, if the preset abnormal feature is a window gap and the abnormal associated area is the master bedroom, the corresponding prompt information may be "please close the master bedroom window". The corresponding prompt information may be determined based on the preset prompt mapping relationship. The preset prompt mapping relationship contains the prompt information corresponding to the combination of the preset abnormal feature and the abnormal associated area. The specific content is not specifically limited in the embodiment of the present application, and can be determined by relevant staff according to historical control data and uploaded to the control system. After determining the prompt information, a target person needs to be determined from the room. The target person may be the mobile target in the above embodiment or other persons. If the mobile target is detected to be still in the abnormal associated area at the current moment, the mobile target can be determined as the target person; if the mobile target is detected not to be in the abnormal associated area at the current moment, the target person needs to be re-determined from the indoor image. The indoor image can be collected by an image acquisition device set indoors and uploaded to the control system. The target area is an adjacent or close area of ​​the abnormal associated area. By determining the target person from the adjacent or close area of ​​the abnormal associated area, it is convenient to improve the response rate of the target person.

[0059] The ambient volume can be collected by a sound sensor installed indoors and uploaded to the control system. Different ambient volumes correspond to different feedback volumes. In order to ensure that the prompt information can be clearly heard by the target person and avoid noise interference, the feedback volume suitable for the ambient volume can be determined based on the preset volume mapping relationship. The preset volume mapping relationship includes feedback volumes corresponding to different ambient volumes, and the specific content is not specifically limited in the embodiments of this application. When the prompt information is fed back, the feedback device can be located and identified in the target area, and the prompt information can be played at the feedback volume through the feedback device. The feedback device can be a speaker, a player, a television, etc. The specific device is not specifically limited in the embodiments of this application, as long as it can play or display the prompt information.

[0060] Furthermore, in order to improve comfort, the method provided in the embodiment of the present application also includes: The direct blowing area is determined based on the set position and original blowing mode of the central air conditioner; when the direct blowing area contains personnel features and the personnel features are in a static state, the static position of the personnel features in the direct blowing area is identified; based on the static position, the set temperature and the operating power of the central air conditioner at the current moment, the non-blowing area is determined; and the original blowing mode of the central air conditioner is adjusted based on the non-blowing area.

[0061] Specifically, the setting position of the central air conditioner is used to characterize the installation position of the central air conditioner indoors, which can be identified from the indoor image or uploaded to the control system in advance by the user. The original blowing mode can be side delivery and downward return, downward delivery and downward return, side delivery and side return, etc., which can be set by the user when turning on the central air conditioner. Different blowing modes correspond to different airflow delivery directions and return air directions. Therefore, the direct blowing areas formed by different setting positions and original blowing models are also different. In cooling mode, if the cold air blown by the central air conditioner blows directly at the human body, it is easy for people to feel too cold and may even cause physical discomfort, such as joint pain, muscle stiffness, etc. In heating mode, if the hot air blows directly at the human body, it may cause dry skin, throat discomfort and other problems. Therefore, direct blowing is generally avoided during the use of central air conditioning, especially for people who are in a static state such as sleeping, reading, and working.

[0062] After determining the direct blowing area, it is possible to identify and judge whether the direct blowing area contains personnel features in a stationary state based on a preset feature recognition algorithm. If so, it is necessary to adjust the original blowing mode of the central air conditioner so that the direct blowing area avoids the personnel features. Among them, the moving positions of the personnel features in the direct blowing area at different times can be identified and recorded to judge whether the personnel features are in a stationary state. If the moving positions of the personnel features at different times are the same, or the distances between the corresponding moving positions at different times are less than a preset distance threshold, it is determined that the personnel features are in a stationary state. Among them, the preset distance threshold can be 5 cm or 8 cm, and the specific values ​​are not limited in the embodiments of the present application.

[0063] The static position is the position of the personnel feature in the direct blowing area. The static position, set temperature and operating power of the personnel feature can be imported into the preset simulation model to determine the non-blowing area. Based on the preset simulation model, the heating effect or cooling effect of the central air-conditioning in the room can be simulated, and the airflow distribution of hot air or cold air in various areas of the room can be intuitively displayed. The non-blowing area is an area with the static position as the center and the preset influence distance as the radius, wherein the preset influence distance can be uploaded to the control system in advance by relevant technical personnel. Furthermore, the preset influence distance can also be adjusted according to the behavioral characteristics of the person. For example, when abnormal behavioral characteristics are detected, the preset influence distance can be increased to expand the non-blowing area, wherein the abnormal behavioral characteristics can be frequent adjustment of clothing, posture changes, etc. The specific abnormal behavioral characteristics are not specifically limited in the embodiments of the present application. The original blowing mode is adjusted by simulation until the simulated direct blowing area does not contain the non-blowing area, and finally the original blowing mode of the central air-conditioning is adjusted based on the simulation adjustment parameters.

[0064] When it is detected that there is a stationary person in the direct blowing area, the non-blowing area is promptly determined, and the original blowing mode of the central air-conditioning is automatically adjusted according to the non-blowing area, so as to avoid the stationary person being in the direct blowing state for a long time, thereby improving the comfort of the stationary person.
