Description

Technical Field

[0001] This invention relates to the field of home appliance control technology, and more specifically, to an energy-saving control method and device for an air conditioner. Background Technology

[0002] Traditional air conditioning control methods often only consider the overall indoor temperature, ignoring the location and activity of people. They operate continuously regardless of whether anyone is in the room, resulting in significant energy waste as the equipment continues to run even when no one is present. Furthermore, traditional air conditioning systems detect occupants through infrared pyroelectric sensing, but this method only detects movement; it cannot detect occupancy when people are stationary, making accurate judgment and energy-saving control difficult. Additionally, infrared thermopile or thermal imaging is limited by its detection range, resulting in significant blind spots and situations where the location of people cannot be determined. Consequently, the air conditioner cannot adjust comfort based on occupant location and fails to achieve energy savings.

[0038] According to an embodiment of the present invention, an energy-saving control method for an air conditioner is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0039] Figure 2 This is a flowchart of an energy-saving control method for an air conditioner according to an embodiment of the present invention, such as... Figure 2 As shown, the method includes the following steps:

[0040] Step S202: After receiving the air conditioner's power-on signal, obtain the heat value of each cell in the scene heat map corresponding to the target room where the air conditioner is located. The scene heat map is an image generated based on the feature information of the target room to represent the activity state of the target object in the target room. Each cell is obtained based on the area division result of the target room. The heat value is determined based on the cumulative duration of the target object in each area of ​​the target room.

[0041] The air conditioner mentioned in the above embodiments of the present invention mainly includes four units: a central control unit (CPU), a data storage and analysis unit, a sensor unit, and a wireless communication unit. The functions of each unit are as follows: 1) The central control unit (CPU) is connected to the sensor unit, the wireless communication unit, the user feedback interface, etc., and is used for logic operations, scheduling control, etc., and can adjust and control the air speed and direction of the air conditioner; 2) The data storage and analysis unit is connected to the central control unit and is used to store thermal image data, user feedback, etc.; 3) The sensor unit is connected to the central control unit and includes a millimeter-wave radar sensor, which is used to detect the target activity status and location information; 4) The wireless communication unit is responsible for network connection, terminal communication, etc., and allows real-time transmission of data and control commands between devices.

[0042] According to the above embodiments of the present invention, before step S202, that is, before obtaining the heat value of each cell in the scene heat map corresponding to the target room where the air conditioner is located, the method further includes: obtaining multiple frames of images of the target room, wherein the multiple frames of images are images obtained by image acquisition of the target room from different angles; generating a three-dimensional image of the target room based on the multiple frames of images; extracting feature information from the three-dimensional image, wherein the feature information includes: size and resolution; generating an initial scene heat map based on the feature information; obtaining multiple cells in the initial scene heat map based on the area division result of the target room, and setting the initial heat value of the multiple cells to obtain the scene heat map.

[0043] For example, firstly, an infrared sensor installed on the air conditioner scans the target room from multiple angles to collect multiple frames of images of the target room; then, a three-dimensional image of the target room is generated based on the collected multiple frames of images; next, feature information such as image size and resolution is extracted from the three-dimensional image, and then an initial scene heat map of the target room is generated based on the extracted image size, resolution and other feature information; finally, based on the previously divided area of ​​the target room, multiple cells in the initial scene heat map are obtained, and the initial scene heat map is initialized by setting the initial heat value of each cell to 0, thus obtaining the scene heat map.

[0044] According to the above embodiments of the present invention, after obtaining the scene heat map, the method further includes: detecting the duration of the target object appearing in each cell in real time using a millimeter-wave radar sensor; determining the cell with a duration greater than a predetermined duration as the target cell; updating the heat value of the target cell to obtain the updated scene heat map; and storing the updated scene heat map.

[0045] The following is combined Figure 3 The embodiments of the present invention will be described in detail below. Figure 3 This is a flowchart of an optional energy-saving control method for an air conditioner according to an embodiment of the present invention.

[0046] like Figure 3 As shown, the location and activity status of indoor users (target objects) are detected in real time by millimeter-wave radar sensors, and the duration of users appearing in each cell is counted. Whenever the duration of time spent in a certain position exceeds a predetermined duration (a pre-set fixed value, such as 10s, 30s, 1min, etc.), the heat value of the corresponding cell is increased by a predetermined increment (a pre-set fixed value, such as 1, 3, 5, etc.) to update the heat value of the corresponding cell, thereby updating the scene heat map, and storing the updated scene heat map in the data storage unit.

[0047] In the above embodiments of the present invention, storing the updated scene heatmap includes: determining the time decay factor of the heat value in the updated scene heatmap; updating the heat value of each cell using the time decay factor according to a predetermined period to update the scene heatmap and obtain the updated scene heatmap; and storing the updated scene heatmap.

[0048] As above Figure 3 As shown, in order to ensure that the scene heatmap reflects the user's recent activity status, a time decay mechanism can be introduced to process all the heat values ​​recorded in the scene heatmap. That is, all the heat values ​​in the scene heatmap are multiplied by a time decay factor according to a predetermined period (a pre-set fixed value, such as 1 day, 3 days, 1 week, etc.), weakening the data from earlier times, and performing noise reduction and filtering out invalid data. This updates the stored scene heatmap again, and the updated scene heatmap is stored in the data storage unit.

[0049] Step S204: Determine the cells with a heat value greater than the heat value threshold as hot cells. The heat value threshold is one of the following: the average or median of the heat values ​​in the scene heat map, or a pre-set fixed value.

[0050] For example, sort the heat values ​​in the scene heatmap and select the median, or calculate the average value of all heat values ​​in the scene heatmap; set the median or average value as the heat threshold, or determine a fixed value as the heat threshold based on experiments or observations; compare each heat value in the scene heatmap with the heat threshold, and determine the cells with heat values ​​greater than the heat threshold as hot cells.

[0051] Step S206: Cluster the hot cells to obtain the hot areas in the scene heatmap.

[0052] As above Figure 3 As shown, there may be multiple hotspot cells identified in the above steps. These hotspot cells may be either scattered or closely connected. Here, clustering algorithms (including but not limited to DBSCAN and K-Means) can be used to cluster the closely connected hotspot cells to form one or more hotspot regions.

[0053] Step S208: When a change in the position of the target object is detected, the air conditioner is controlled to deliver air to the target hot spot area with the lowest power consumption. The target hot spot area is the area where the target object was located before the position change. The lowest power consumption means the power consumption when the cooling efficiency of the air conditioner reaches the cooling efficiency threshold and the heat output efficiency reaches the heat output efficiency threshold.

[0054] For example, a millimeter-wave radar sensor can detect the user's location and activity status in real time. When a change in the user's location is detected, the air conditioner can be controlled to switch to energy-saving mode to deliver air to the area where the user was located before the change of location (the target hotspot area, the same below) with the lowest power consumption.

[0055] According to the above embodiments of the present invention, in step S208, controlling the air conditioner to deliver air to the target hotspot area with the lowest power consumption includes: calculating the center position of the target hotspot area by weighting multiple hotspot cells in the target hotspot area using a first formula and a second formula, wherein the first formula is: The second formula is: , Indicates the label of each hot cell. This indicates the total number of hotspot cells in the target hotspot area. The x-coordinate of the hot cell. The vertical coordinate of the hot cell. Indicates the heat value. The x-coordinate representing the center position. The vertical coordinate represents the center position; it controls the air conditioner to deliver air to the center of the target hotspot area with minimal power consumption.

[0056] As above Figure 3 As shown, after identifying the hotspot areas in the scene heatmap, the center position of the hotspot area can be obtained by weighted calculation of the coordinates of multiple hotspot cells within that area. That is, using the formula: Calculate the x-coordinate of the center position using the formula: Calculate the ordinate of the center position, where, Indicates the label of each hot cell. This indicates the total number of hotspot cells in the target hotspot area. The x-coordinate of the hot cell. The vertical coordinate of the hot cell. Indicates the heat value. The x-coordinate representing the center position. The vertical coordinate represents the center position; after calculating the center position of each hotspot area, it can be marked on the scene heat map to provide a reference for adjusting the air conditioner's airflow direction or speed.

[0057] According to the above embodiments of the present invention, in step S208, controlling the air conditioner to deliver air to the target hotspot area with the lowest power consumption includes: during the process of controlling the air conditioner to deliver air to the target hotspot area with the lowest power consumption, counting the total time the target object leaves the target hotspot area; when the total time is greater than a preset time, controlling the air conditioner to stop operating; when the total time is not greater than the preset time, controlling the air conditioner to deliver air to hotspot areas other than the target hotspot area, or controlling the air conditioner to deliver air to the target hotspot area with the lowest power consumption; when the target object returns to the target hotspot area, controlling the air conditioner to return to the operating mode when the target object has not left the target hotspot area.

[0058] As above Figure 3 As shown, after detecting a change in the user's location, while controlling the air conditioner to deliver air to the area where the user's location changed at the lowest power consumption, the total time the user spent away from the original area is simultaneously counted. If the counted time is greater than a preset time (a pre-set fixed value, such as 30 minutes, 45 minutes, 1 hour, etc.), the air conditioner is controlled to stop operating. If the counted total time is less than the preset time, the air conditioner is controlled to deliver air to the center of the area where the user's location changed at the lowest power consumption, or the air conditioner is controlled to activate a multi-directional air supply mode to deliver air to other areas that the user might go to (hotspot areas other than the target hotspot area). If, during the above process, it is detected that the user has returned to the area where the location changed, the air conditioner is controlled to return to the operating mode before the user left the area.

[0059] According to the above embodiments of the present invention, controlling the air conditioner to supply air to hot spots other than the target hot spot area includes: determining the priority of each hot spot area other than the target hot spot area when the total duration is not greater than a preset duration and when the target object leaves the target hot spot area; and controlling the air conditioner to supply air to each hot spot area other than the target hot spot area according to the priority.

[0060] Optionally, the above priority can be determined by sorting the sum of all popularity values ​​in each hotspot area. Of course, the methods for determining the priority may include, but are not limited to, the above methods.

[0061] For example, you can first calculate the sum of all the heat values ​​in each hotspot area, then sort them in descending order, and determine the priority of each hotspot area based on the sorting results. The hotspot area that is ranked earlier has a higher priority, and the hotspot area that is ranked later has a lower priority.

[0062] In addition, users can set priorities for each hotspot area. They can also set different energy-saving operation control reference strategies for specified areas.

[0063] In the above embodiments of the present invention, controlling the air conditioner to supply air to each hot spot area other than the target hot spot area according to priority includes: determining the air supply duration of the air conditioner to each hot spot area other than the target hot spot area according to priority; and controlling the air conditioner to supply air to each hot spot area other than the target hot spot area in sequence according to the air supply duration.

[0064] For example, after determining the priority of each hotspot area, the air supply duration of the air conditioner to each hotspot area other than the target hotspot area is determined according to the priority. The highest priority is set to 10 minutes, the second highest priority is set to 6 minutes, and so on. Then, the air conditioner is controlled to supply air to each hotspot area other than the target hotspot area in turn according to the air supply duration. This cycle is repeated until the current air conditioner is no longer operating in the current mode.

[0065] According to the above embodiments of the present invention, the energy-saving control method of the air conditioner may further include: obtaining the current time and inputting the current time into the operation mode prediction model, so as to process the current time using the operation mode prediction model to obtain the target air supply position corresponding to the current time, wherein the operation mode prediction model is trained by machine learning using multiple sets of training data, and each set of training data includes: historical time and historical air supply position corresponding to the historical time; controlling the air conditioner to supply air to the target air supply position within the time period corresponding to the current time.

[0066] Machine learning algorithms, such as time series forecasting, can be used to help the system better predict the activity patterns of air conditioners in future time periods. Specifically, when the system learns from the acquired time data and observes the stability of certain patterns during this period, for example, if a certain area is always very active from 2 pm to 4 pm every day, relevant data can be acquired to train an air conditioner operation mode prediction model, and the air conditioning strategy can be adjusted in advance based on the model at similar times in the future.

[0067] As above Figure 3 As shown, it can detect whether user feedback or other input is received in real time, and optimize based on the user's feedback or input to provide a better user experience. As can be seen from the above steps, after receiving the air conditioner's power-on signal, the heat value of each cell in the scene heat map corresponding to the target room where the air conditioner is located can be obtained. The scene heat map is an image generated based on the feature information of the target room to represent the activity state of the target object in the target room. Each cell is obtained based on the regional division results of the target room, and the heat value is determined based on the cumulative duration of the target object appearing in each region of the target room. Cells with heat values ​​greater than a heat threshold are identified as hotspot cells. The heat threshold is one of the following: the average or median of the heat values ​​in the scene heat map, or a pre-set fixed value. Hotspot cells are clustered to obtain hotspot areas in the scene heat map. Upon detecting the target object... When the object's location changes, the air conditioner is controlled to deliver air to the target hotspot area with the lowest power consumption. The target hotspot area is the area where the object was located before the location change. The lowest power consumption means that the air conditioner's cooling efficiency reaches the cooling efficiency threshold and its heat output efficiency reaches the heat output efficiency threshold. This achieves the goal of generating a scene heat map based on the characteristic information of the room where the air conditioner is located, determining the hotspot cells in the scene heat map based on the cumulative time the user appears in each area, and then clustering them to obtain multiple hotspot areas. When a change in the user's location is detected, air is delivered to the target hotspot area with the lowest power consumption. This achieves the technical effect of intelligently adjusting the air conditioner parameters according to the user's activity status and location in each area of ​​the room, reducing resource waste.

[0068] Therefore, the technical solution provided by the above embodiments of the present invention solves the technical problem in the related art that traditional air conditioners cannot intelligently adjust the air conditioner parameters according to the activity status and location of people in different areas of the room where the air conditioner is located, thus causing resource waste.

Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of this application, in essence, or the part that contributes to the prior art, can be embodied in the form of a software product. This computer software product is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes several instructions to cause a terminal device (which may be a mobile phone, computer, server, or network device, etc.) to execute the methods described in the various embodiments of this application.

[0071] According to embodiments of the present invention, an energy-saving control device for an air conditioner for implementing the above-described energy-saving control method for an air conditioner is also provided. Figure 4 This is a schematic diagram of an energy-saving control device for an air conditioner according to an embodiment of the present invention, such as... Figure 4 As shown, the device includes: a first acquisition unit 41, a first determination unit 43, a second acquisition unit 45, and a first control unit 47. The energy-saving control device for this air conditioner will be described in detail below.

[0072] The first acquisition unit 41 is used to acquire the heat value of each cell in the scene heat map corresponding to the target room where the air conditioner is located after receiving the air conditioner's power-on signal. The scene heat map is an image generated based on the feature information of the target room to represent the activity state of the target object in the target room. Each cell is obtained based on the area division result of the target room. The heat value is determined based on the cumulative duration of the target object in each area of ​​the target room.

[0073] The first determining unit 43 is used to determine the cells with a heat value greater than the heat value threshold as hot cells. The heat value threshold is one of the following: the average or median of the heat values ​​in the scene heat map, or a pre-set fixed value.

[0074] The second acquisition unit 45 is used to perform clustering processing on hotspot cells to obtain hotspot areas in the scene heatmap.

[0075] The first control unit 47 is used to control the air conditioner to deliver air to the target hot spot area with the lowest power consumption when a change in the position of the target object is detected. The target hot spot area is the area where the target object was located before the change in position. The lowest power consumption means the power consumption when the cooling efficiency of the air conditioner reaches the cooling efficiency threshold and the heat output efficiency reaches the heat output efficiency threshold.

[0076] It should be noted here that the first acquisition unit 41, the first determination unit 43, the second acquisition unit 45 and the first control unit 47 mentioned above correspond to steps S202 to S208 in the above embodiments. The four units and the corresponding steps implement the same instances and application scenarios, but are not limited to the content disclosed in the above embodiments.

[0077] As can be seen from the above, in the solution described in the above embodiments of the present invention, the first acquisition unit can acquire the heat value of each cell in the scene heat map corresponding to the target room where the air conditioner is located after receiving the air conditioner's power-on signal. The scene heat map is an image generated based on the feature information of the target room to represent the activity state of the target object in the target room. Each cell is obtained based on the area division result of the target room, and the heat value is determined based on the cumulative duration of the target object appearing in each area of ​​the target room. Then, the first determination unit determines cells with heat values ​​greater than a heat threshold as hotspot cells. The heat threshold is one of the following: the average or median of the heat values ​​in the scene heat map, or a pre-set fixed value. Afterwards, the second acquisition unit performs clustering processing on the hotspot cells to obtain the heat values ​​in the scene heat map. The system identifies hotspot areas; finally, when the first control unit detects a change in the target object's position, it controls the air conditioner to deliver air to the target hotspot area with the lowest power consumption. The target hotspot area is the area where the target object was located before the position change. The lowest power consumption represents the power consumption at which the air conditioner's cooling efficiency reaches the cooling efficiency threshold and its heat output efficiency reaches the heat output efficiency threshold. This achieves the goal of generating a scene heat map based on the characteristic information of the room where the air conditioner is located, determining hotspot cells in the scene heat map based on the cumulative duration of the user's presence in each area, and then clustering them to obtain multiple hotspot areas. When a change in the user's position is detected, air is delivered to the target hotspot area with the lowest power consumption. This achieves the technical effect of intelligently adjusting the air conditioner parameters based on the user's activity and location in each area of ​​the room, reducing resource waste.

[0078] Therefore, the technical solution provided by the above embodiments of the present invention solves the technical problem in the related art that traditional air conditioners cannot intelligently adjust the air conditioner parameters according to the activity status and location of people in different areas of the room where the air conditioner is located, thus causing resource waste.
