Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. And can be adjusted as needed by those skilled in the art to suit particular applications.
As shown in fig. 1, a flowchart of main steps of an intelligent air conditioner control method based on millimeter wave radar according to an embodiment of the present invention includes:
step S101: establishing a natural environment model of a room based on a measurement result of the millimeter wave radar;
step S102: detecting the current position and the stay time of the personnel through a millimeter wave radar;
step S103: determining a corresponding home scene according to the current position, the stay time, the current time and the inherent environment model of the room of the person;
step S104: determining an operation mode of an air conditioner according to the home scene;
these steps will be described in detail separately below.
Step S101: based on the measurement results of the millimeter wave radar, a natural environment model of the room is established. As shown in fig. 2, a method for establishing a room environment model according to an embodiment of the present invention includes the following steps:
step S201: scanning the whole room by the millimeter wave radar sensor to obtain a room floor plan;
step S202: synchronizing the room layout to air conditioner control setting software;
step S203: measuring and recording information such as position, shape, size and the like of home in a room by a user;
step S204: a user manually demarcates a use area of each home by using air conditioner control setting software according to information such as positions, shapes and sizes of furniture such as sofas, dining tables, desks and beds in a room, and sets scene areas such as a sofa area, a dining table area, a desk area and a bed area;
step S205: setting the use type of a room, such as a living room, a bedroom, etc.;
at this point, the building of the natural environment model of the room is completed.
In this embodiment, the hardware carrier for running the air conditioner control setting software includes, but is not limited to: wire controller, smart mobile phone, panel computer, notebook computer, desktop etc..
In the present embodiment, the inherent environment model information of the room includes, but is not limited to: house type map, area of use of furniture, type of room use, house orientation, door and window position, etc.
In this embodiment, the types of usage of the room include, but are not limited to: living room, bedroom, kitchen, study, etc.
Step S102: and detecting the current position and the stay time of the personnel through a millimeter wave radar. The millimeter wave radar detects the positions of the personnel in the room in real time, matches the positions with the inherent environment model of the room, determines the scene areas where the personnel are located, and records the continuous stay time of the personnel in each scene area.
As an example, the rule of the stay timing of the people scene area is: after the millimeter wave radar detects that someone enters a certain furniture area, the air conditioner controller starts timing; when the existence of the personnel is not detected within more than 30 seconds continuously in the area, the personnel staying time in the area is timed to be terminated and cleared; when the presence of a person in the area is detected again, the area person stay timing is restarted. It should be noted that the above description is only an example, and it is obvious to those skilled in the art that the timing rule for the stay of the regional personnel can be made as required, and the specific content of the timing rule should not be construed as limiting the scope of the present invention.
Step S103: and determining a corresponding home scene according to the current position, the stay time, the current time and the inherent environment model of the room of the person. Specifically, as shown in fig. 3, the method for determining a corresponding home scene according to the current position, the stay time, the current time, and the inherent environment model of the room includes the following steps:
step S301: matching the personnel position information with the inherent environment model of the room to determine the scene area of the personnel;
step S302: recording the stay time of the personnel scene area;
step S303: judging whether the stay time of the personnel scene area reaches a set threshold value or not so as to determine the activity of personnel in the scene area;
step S304: and determining a home scene according to the current time.
In step S303, it is determined whether the stay time of the person scene area reaches a set threshold to determine that the person is active in the scene area. Specifically, the person needs to stay in a certain scene area for a certain time, and the person can be considered to be moving in the scene area after the time length reaches a set threshold value.
As an example, the threshold setting reference is:
the first set threshold, 5 minutes, is used for table area determination.
And a second set threshold value of 5 minutes is used for judging the sofa area.
And setting a threshold value for 10 minutes for judging the sleeping time period bed area.
The fourth set threshold, 20 minutes, is used for the non-sleep period bed area determination and should be greater than the third set threshold for the sleep period.
More specifically, when the millimeter wave radar detects that the personnel stay in the dining table area for less than 5 minutes, the air conditioner keeps the original running state and does not judge the home scene; and starting the judgment of the home scene when the personnel stay in the dining table area and continuously accumulate for 5 minutes or more.
Meanwhile, different threshold values can be set in the same scene area, and people are in different home scenes by combining the current time.
In step S304, a home scene is determined according to the current time. In daily life, people often schedule different activities according to time, and the same scene area can be used for different purposes at different times. For example, the sofa area is typically used for home activities such as watching television, playing games, etc.; and can be used as a dining place during the dining time. Therefore, the judgment of the home scene is closely related to the current time.
Accordingly, 24 hours a day may be divided as follows:
00: 00-05: 59: sleep periods
06: 00-07: 59: at dining time interval
08: 00-11: 29: general time period, which can schedule any activity
11: 30-12: 59: at dining time interval
13: 00-17: 59: general time period, which can schedule any activity
18: 00-19: 29: at dining time interval
19: 30-22: 29: general time period, which can schedule any activity
22: 30-23: 59: a sleep period.
Accordingly, several common household scenarios can be defined as follows:
dining scene: the personnel are having a meal, and the period is the period of having a meal, considers different habits and customs, and personnel have a meal probably in sofa region or dining table region.
Leisure scene: people are chatting, watching television, playing games or performing other household activities, and are usually scheduled in a general time period, and the place may be in a sofa area or a dining table area.
A sleep scene: the person is at rest, with time typically during sleep periods and location typically in bed.
Reading a scene: people are reading, writing, home working, etc. and the location is usually in the desk area, and the time period factor can be not considered.
A conventional scene: the default scene mode is usually the case when no person is in the room or a person enters the room but the scene area determination condition is not met.
The determination of the home scenario is further illustrated by several examples below.
In this embodiment, a method for determining a home scene when all people are located in a single scene area is described with reference to fig. 4. Setting a room as a living room, wherein the inherent environment model comprises a sofa area and a dining table area, and the millimeter wave radar detects that the stay time of the personnel in the dining table area reaches a set threshold value.
Scene 1: the current time is 12: 00.
Scene 2: the current time is 20: 30.
Judgment of scene 1: the current time is 12:00, the dining time interval is included, and the home scene is determined to be a dining scene.
And (3) judging a scene 2: the current time is 20:30, and belongs to a general time period, although the person is in the dining table area, the person may be in a dining table game or chat at the moment considering that the dining time usually passes, the possibility of dining is low, and therefore the home scene is determined to be a leisure scene.
In this embodiment, a method for determining a home scene when a person is located in a plurality of different scene areas will be described with reference to fig. 5. The room is set as a living room, the inherent environment model comprises a sofa area and a dining table area, and the millimeter wave radar detects that people stay in the dining table area and the sofa area at the same time and both exceed a set threshold value.
Scene 1: the current time is 12: 00.
Scene 2: the current time is 20: 30.
Scene 3: the current time is 23: 00.
Judgment of scene 1: the current time is 12:00, the dining time interval is included, and the home scene is determined to be a dining scene.
And (3) judging a scene 2: the current time is 20:30, which belongs to a general time period, although the person is in the dining table area, the person may play or chat at the dining table, the possibility of dining is low, the person may play or chat at the dining table, and the person stays in the sofa area, so that the home scene is determined to be a leisure scene.
And (3) judging a scene: the current time is 23:00, which belongs to a sleep period, and the sofa area is usually the main area of living room personnel activity, so the sofa area can be considered preferentially, and people may sleep on the sofa considering that the time belongs to the sleep period, and people usually select a softer air conditioning control mode late at night, so that the home scene is determined to be a sleep scene.
In this embodiment, a method for determining a home scene when there are a plurality of set thresholds in the same scene area will be described with reference to fig. 6. Setting the room as a bedroom, setting the inherent environment model to include a bed area, and referring to the above, setting the third threshold value to be 10 minutes, setting the fourth threshold value to be 20 minutes, and detecting that a person stays in the bed area by the millimeter wave radar.
Scene 1: the current time was 23:00 and the bed area residence time was 15 minutes.
Scene 2: the current time was 14:30 and the bed area residence time was 15 minutes.
Scene 3: the current time was 14:30 and the bed area residence time was 25 minutes.
Judgment of scene 1: the current time is 23:00, the current time belongs to a sleep period, the millimeter wave radar detects that the stay time of the people in the bed area is 15 minutes, the stay time reaches a third set threshold value for 10 minutes, and the current time is in the sleep period, so that the fourth set threshold value does not need to be judged for 20 minutes, and the home scene is determined to be a sleep scene.
And (3) judging a scene 2: the current time is 14:30, the current time belongs to a common time period, the millimeter wave radar detects that the stay time of the people in the bed area is 15 minutes, the third set threshold value is reached for 10 minutes, and the fourth set threshold value is required to be judged for 20 minutes because the current time is in the common time period. At this time, the stay time of the people in the bed area does not reach the fourth set threshold value for 20 minutes, and the home scene is not updated.
And (3) judging a scene: the current time is 14:30, the time belongs to the common time period, the millimeter wave radar detects that the stay time of the people in the bed area is 25 minutes, the third set threshold value is reached for 10 minutes, and the fourth set threshold value needs to be judged for 20 minutes because the current time is in the common time period. At the moment, the stay time of the people in the bed area reaches the fourth set threshold value for 20 minutes, and the home scene is determined to be a sleep scene in consideration of the fact that the people stay in the bed area for a long time and possibly take a rest.
Finally, in step S104, an operation mode of the air conditioner is determined according to the home scene. Corresponding to several common household scenes, the operation mode of a common air conditioner is defined as follows: a dining scene, a leisure scene, a sleeping scene, a reading scene, and a regular scene.
Each air conditioner operation mode comprises but is not limited to control of parameters and operation modes such as temperature, a wind sweeping mode, ventilation, air freshening and dehumidification, and the like, and can control wind sweeping air quantity, wind sweeping speed, wind sweeping angle and the like by matching with personnel position data provided by the millimeter wave radar, so that the wind sweeping strategy of the air conditioner is optimized, the comfort level of indoor personnel is improved, and no wind feeling is realized.
As an example, in the dining mode, the sweeping area of the air conditioner should avoid the dining table area, but the set temperature may be lower than the standard mode, and the air volume may be larger than the standard mode, because a person takes in calories at the time of dining and feels hotter, but is not suitable for direct blowing at this time. Compared with a dining mode, in the leisure mode, the air sweeping area of the air conditioner can cover the whole room, the set temperature can be smaller than or equal to the standard mode temperature, and the air volume can be larger than or equal to the standard mode air volume. Similarly, in the sleep mode, the air conditioner should stop blowing air, gently blow air obliquely upward, and the set temperature should be higher than the standard mode temperature. In the reading mode, the air sweeping area of the air conditioner should avoid the desk area, the set temperature can be greater than or equal to the standard mode temperature, and the air volume can be less than or equal to the standard mode air volume.
It should be noted that although the air-conditioning modes in several home scenarios and the specific contents of each air-conditioning mode are listed here, those skilled in the art can understand that these examples should not set any limit to the scope of the present invention. Without changing the basic principle of the present invention, those skilled in the art can add or reduce the home scenes and the air-conditioning modes and adjust the specific control content of each air-conditioning mode according to the actual application.
It should also be noted that, although the above embodiments describe each step in a specific sequence, those skilled in the art can understand that, in order to achieve the effect of the present invention, different steps do not have to be executed in such a sequence, and they may be executed simultaneously (in parallel) or in other sequences, and these changes are all within the protection scope of the present invention.
In addition, due to objective differences such as time zones, living habits, and idioms, it is obvious for those skilled in the art to name and define the contents such as scene areas, home scenes, and air conditioning control modes autonomously, and the personalized named contents should not limit the scope of the present invention.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
