Based on the method provided by the embodiment of the invention, when the user around the air conditioner is sensed, the relative position parameter of the user relative to the air conditioner can be obtained in time, and the air conditioner is started to set the air supply mode, so that the operation parameter of the air conditioner is intelligently adjusted by effectively combining the air supply mode and the relative position parameter, and the intelligent human body induction control of the air conditioner is realized.
Optionally, the human body induction device in this embodiment prefers to use a millimeter wave radar sensor, and the millimeter wave radar sensor is not only strong in anti-interference ability but also can penetrate through general non-metallic materials, thereby realizing hidden human body induction. In the embodiment, the millimeter wave radar sensor can be arranged in the air conditioner to sense the human body within the set distance range of the air conditioner, so that the sensing precision is high, the influence of factors such as temperature, humidity, airflow, dust, noise, brightness and the like is avoided, and the anti-interference capability is high; but also can penetrate acrylic, glass and thin non-metallic materials, and the appearance of the air conditioner can not be damaged when the air conditioner is arranged in the air conditioner. The preset distance range of the air conditioner may be a preset space area which is a certain distance away from the air conditioner, and the preset distance range may be specifically set according to the size of the space where the air conditioner belongs and different requirements, which is not limited in the present invention.
In an optional embodiment of the present invention, before the human body sensing device identifies the relative position parameter between the user and the air conditioner in step S104, a spatial region within a set angle from a horizontal center line of the air conditioner may be further divided into a plurality of sub-spatial regions based on the vertical center line of the air conditioner.
In this embodiment, a space region sensed by a human body is determined based on a vertical center line of the air conditioner, and the space region is further divided into a plurality of sub-space regions. Fig. 2 shows a schematic diagram of spatial region division according to an embodiment of the present invention. As shown in fig. 2, the broken line shown in fig. 2 is assumed to be the vertical center line of the air conditioner (the rectangular frame shown in fig. 2 is a plan view of the air conditioner, and the upper side shown in fig. 2 is the front side of the air conditioner), and a space region formed with a horizontal angle of 60 ° or less with the broken line is set and divided, that is, a space of 120 ° between a straight line L1 and a straight line L2 is divided as a space region in which the air conditioner senses a human body. In addition, when the space region is divided, the space of 120 ° may be equally divided, for example, the included angle of L1 and L3, the included angle of L3 and L4, and the included angle of L4 and L2 are both set to 30 °, so that the space between L1 to L2 is equally divided into the subspace region a, the subspace region B, and the subspace region C in fig. 2. In practical applications, the division of the spatial regions may be performed by combining with the spatial layout of the environment in which the air conditioner belongs or other factors, and the present invention is not limited thereto.
In this embodiment, the space region of human body induction is determined, and after the space region is further divided into a plurality of subspace regions, when the relative position parameters of the user and the air conditioner are identified by using the human body induction device, the first subspace region where the user is located in the space region can be identified by using the human body induction device, and then the angle of the swing blade arranged at the air outlet of the air conditioner is regulated and controlled based on the first subspace region and the air supply mode.
Alternatively, the air supply mode in the present embodiment may include two modes of the manned air supply and the manned air avoidance supply. In the above step S106, the air supply mode of the air conditioner may be set after the air conditioner is started, and in an optional embodiment of the present invention, when the air supply mode of the air conditioner is set, the control instruction from a user of the air conditioner may be received, and the air supply mode of the air conditioner may be set in response to the control instruction; or acquiring a historical air supply mode when the air conditioner is started and operated last time, and operating the air conditioner in the historical air supply mode. That is, when setting the air supply mode of the air conditioner, the current air supply mode of the air conditioner can be set through the instruction of the air supply mode of the air conditioner sent by the user through the remote controller of the air conditioner or other control terminals. If the user does not send the instruction for setting the air supply mode of the air conditioner through the control terminal, the air supply mode can be continuously operated when the air conditioner is started and operated last time. Aiming at different air supply modes of the air conditioner, the angles of the swing blades at the air outlet of the air conditioner are different, the angles of the swing blades at the air outlet can be set according to the position of a user, and the air sent out from the air outlet can be directly blown to the user by adjusting the angles of the swing blades at the air outlet in a person-following mode; in the person avoidance mode, the wind sent out through the air outlet avoids the user, and the specific angle of the swing blade can be set according to the distribution characteristics and the space size of the environment where the air conditioner belongs, and the invention is not limited.
As mentioned above, the angle of the swing blade disposed at the air outlet is adjusted and controlled by combining the first subspace region where the user exists and the air supply mode. Optionally, the swing blade at the air outlet of the air conditioner in this embodiment may include a plurality of horizontal swing blades and a plurality of vertical swing blades, and when the angle of the swing blade at the air outlet of the air conditioner is adjusted, the angles of the plurality of horizontal swing blades and the plurality of vertical swing blades may be adjusted and controlled respectively.
Fig. 3 and 4 are schematic angle diagrams of a single yaw blade and a single vertical yaw blade at an air outlet of an air conditioner according to an embodiment of the present invention. Referring to fig. 3, the adjustment of the angle of the yaw blade mainly adjusts the angle of the yaw blade with respect to a vertical line y, which may be a vertical center line of a rotating shaft of the yaw blade. S1 to S5 in fig. 3 respectively show different positions corresponding to different angles of the yaw blade, and in practical applications, the angle of the yaw blade relative to the rotating shaft thereof can be adjusted according to different requirements.
Referring to fig. 4, the adjustment of the angle of the vertical swing blade mainly adjusts the angle of the vertical swing blade with respect to a horizontal line x, which may be a horizontal center line at the rotating shaft of the vertical swing blade. L1 to L5 in fig. 4 respectively show different positions corresponding to different angles of the vertical swing blade, and in practical application, the angle of the vertical swing blade relative to the rotating shaft thereof can be adjusted according to different requirements.
The scheme that this embodiment provided divides into a plurality of subspace regions through the human response region to the air conditioner to the air supply speed and the angle of air conditioner air outlet department pendulum leaf of according to the region and the air supply mode control air conditioner in user's place, thereby make the wind that the air conditioner blew off accord with user's user demand more, further promote user's comfort level.
Besides the above-mentioned human body sensing device can identify the relative position parameter between the user and the air conditioner, it can also obtain the relative distance between the user and the air conditioner, and then utilize the relative distance to regulate and control the air supply speed of the air conditioner. The relative distance can be the distance between the user and the central point of the air conditioner or the distance between the user and other designated positions on the air conditioner. In practical application, the distance between the user and the air conditioner can be divided into three sections, namely a section I, a section II and a section III. The distance range represented by the area I is 0-2 meters, and the air conditioner supplies air at low wind speed within the distance range between a user and the air conditioner; the distance range represented by the area II is 2-5 meters, and the air conditioner supplies air at a medium wind speed within the distance range between the user and the air conditioner; the distance range represented by the area III is 2-5 m, and the air conditioner supplies air at a high wind speed within the distance range between the user and the air conditioner. In the cooling mode, the low wind speed may be 680 revolutions, the medium wind speed may be 840 revolutions, and the high wind speed may be 920 revolutions. In the heating mode, the low wind speed may be 600 revolutions, the medium wind speed may be 650 revolutions, and the high wind speed may be 830 revolutions. If the air conditioner is in the condition of starting the electric heating, the air conditioner can still be controlled to run at the medium wind speed even if the low wind speed running condition is met, so that the current state of the air conditioner meets the requirement of a user. In addition, if the user manually adjusts the wind speed, the control command sent by the user is preferentially executed. The embodiment only schematically illustrates the division of the distance ranges and the wind speeds corresponding to the distance ranges in the heating mode and the cooling mode, and in practical application, the division may be set according to the size of the deployment space of the air conditioner, the weather environment of the geographic location, and other factors, which is not limited in the present invention.
The scheme provided by the embodiment is that the human body sensing device senses that a user exists in the preset distance range of the air conditioner. It should be noted that, if the human body sensing device senses that no person is in the preset distance range of the air conditioner, and the continuous set time period (such as 180 minutes) is the same, the air conditioner is controlled to enter a standby state, the internal and external fans are stopped at the moment, the press is stopped, the horizontal and vertical guide plates are in the default positions, the human body sensing device continuously works at the moment, and when a person is detected, the air conditioner is started according to an instruction before the air conditioner is turned off.
In the embodiment of the invention, a human body characteristic acquisition device (such as a temperature sensor, an image acquisition device and the like) can be arranged at the air outlet of the air conditioner, so that the attribute characteristics (such as children, males, females, the elderly, adults and the like) of the user can be judged according to the acquired human body characteristic information (such as the characteristics of body surface temperature, height and the like), the operation parameters of the air conditioner can be regulated and controlled according to the attribute characteristics of the user, and the temperature regulation strategy can be customized for each user in a personalized manner.

In this embodiment, the millimeter wave radar sensor may be disposed in the air conditioner 500 to sense a human body in a distance range set by the air conditioner 500, which not only has high sensing accuracy, but also does not damage the appearance of the air conditioner 500. The preset distance range of the air conditioner 500 may be a preset space area with a certain distance from the air conditioner 500, and may be specifically set according to the size of the space in which the air conditioner 500 belongs and different requirements, which is not limited in the present invention.

When the air supply mode is set after the controller 530 starts the air conditioner 500, the controller may receive a control command from a user of the air conditioner 500, and set the air supply mode of the air conditioner 500 in response to the control command; or acquiring a historical air supply mode of the air conditioner 500 during the last starting operation, and controlling the air conditioner 500 to operate in the historical air supply mode; the air supply mode comprises a person following mode and a person avoiding mode.

As shown in fig. 2, the broken line shown in fig. 2 is assumed to be the vertical center line of the air conditioner 500, and a space region formed with a horizontal angle of 60 ° or less with the broken line is set to be divided, that is, a space of 120 ° between the straight line L1 and the straight line L2 in fig. 2 is set as a space region in which the air conditioner 500 performs human body sensing, and the space between L1 and L2 is equally divided into a subspace region a, a subspace region B, and a subspace region C. In practical applications, the division of the spatial regions may be performed by combining with the spatial layout of the environment in which the air conditioner 500 belongs or other factors, and the present invention is not limited thereto.
Optionally, the main air conditioner 510 has at least one air outlet, and the main air conditioner 510 in the air conditioner 500 shown in fig. 5 has two air outlets, namely a first air outlet 511 and a second air outlet 512, which may be respectively located at the upper portion and the lower portion of the air conditioner 500, or respectively located at the left side and the right side.
