The execution subject of the present invention may be an air conditioner, or may be a server, or another terminal, and the following explains an embodiment of the present invention with an air conditioner as an execution subject.
In practical use, when the air conditioner is installed, the angle range of the air conditioner action space can be obtained according to the installation position of the air conditioner, then the action space of the air conditioner is divided into a plurality of detection areas, the division standard can be divided according to the angle, for example, the action space of the air conditioner can be equally divided into a plurality of detection areas, the angle range corresponding to each detection area is the same, optionally, the division of the detection areas can be divided by combining the detection angle range of the human body sensor, for example, when the total angle of the action space of the air conditioner is 180 degrees, and the detection angle of the human body sensor is 90 degrees, the action space of the air conditioner can be divided into 3 detection areas, the angle of each detection area is 60 degrees, one boundary of the action spaces of the air conditioner is set as a starting edge, the angle ranges corresponding to the detection areas are 0-60 degrees respectively, 60 degrees to 120 degrees and 120 degrees to 180 degrees; alternatively, the operating space of the air conditioner may be divided into smaller regions, for example, the operating space of the air conditioner may be divided into 12 detection regions on average, and each detection region may have an angle of 15 °.
When the air conditioner is operated and is controlled according to the human body characteristics, the human body sensor detects the human body characteristics in real time, when the human body is detected, the air conditioner controls the air conditioner according to the detected human body characteristics, meanwhile, the detection area where the human body is located and the time length of the human body are recorded, and the time length of the human body and the detection area where the human body is located are stored in a correlated mode, so that the air conditioner can obtain the accumulated time length of the human body corresponding to each detection area.
When the air conditioner operates, a target area in a preset detection area is determined, the target area is a detection area with the accumulated time length of a human body in a preset time length (first preset time length) meeting a preset condition, and the preset detection area comprises a plurality of detection areas divided by an action space of the air conditioner. Specifically, the air conditioner acquires the accumulated time length of the human body appearing in each detection area within a preset time length, the ending time point of the preset time length is the current time point, the starting time point is the time point (the starting time point is before the ending time point) which is separated from the current time point by the preset time length, the preset time length can be set according to the actual situation, for example, the preset time length can be set to be one day or one week and the like. And then acquiring a detection area with the accumulated duration meeting a preset condition, and taking the acquired detection area as the target area. The preset conditions can be set according to actual conditions, and in practical use, the range of motion of a user in the air conditioner action space generally has strong regularity, for example, when the action space of the air conditioner is a bedroom, the user mainly moves in a detection area where a bed is located in the air conditioner action space, so that the greater the cumulative duration of a human body in each detection area, the greater the probability that the user moves in the detection area, and therefore, the preset conditions can be set to be greater than or equal to the preset duration threshold value, that is, when the cumulative duration of the human body is greater than or equal to the preset duration threshold value, the cumulative duration of the human body meets the preset conditions, and the corresponding detection area is taken as the target area. It is understood that there may be a plurality of detection regions where the accumulated time length of the human body is greater than or equal to the preset time length threshold. The preset duration can be set according to the actual situation, and is not particularly limited herein, for example, the preset duration threshold can be set according to the frequency of the user activity in the air conditioner action space. In addition, the detection area where the cumulative duration of the human body appears is the area where the user most frequently moves, so optionally, the preset condition may also be set to be the maximum in each cumulative duration, that is, when the cumulative duration of the human body appears is the maximum in each cumulative duration, and the cumulative duration of the human body appears meets the preset condition, the detection area corresponding to the cumulative duration of the human body appears is taken as the target area.
It can be understood that, when the air conditioner is used for the first time or the use time is shorter than the preset time, the accumulated time of the human body appearing in each region in the preset time cannot be acquired, at this time, the device can be driven to drive the human body sensor to perform human body detection (for example, performing reciprocating scanning in the whole action space of the air conditioner) in a conventional manner, and when the human body is detected, the time of the human body appearing is stored in association with each detection region; or, the preset duration may be scanned for each detection area, and when a human body is detected, the duration in which the human body appears is stored in association with each detection area.
And step S20, controlling the driving device according to the target area, and adjusting the detection position of the human body sensor so that the human body sensor detects the human body characteristics in the target area.
After the target area is obtained, the obtained target area is an area where a user frequently moves, the air conditioner controls the driving device according to the target area, and the detection position of the human body sensor is adjusted, so that the human body sensor detects human body characteristics in the target area.
Specifically, the air conditioner may determine a detection angle range corresponding to the human body sensor according to the target area, where an area corresponding to the detection angle range includes the target area. The detection angle range corresponding to the human body sensor can be determined according to the angle range corresponding to the target area and the detection angle of the human body sensor, for example, the detection angle of the human body sensor is 90 degrees, one boundary of an action space of the air conditioner is set as a starting edge, and the angle ranges corresponding to the detection areas are respectively 0-60 degrees, 60-120 degrees and 120-180 degrees (the angle in the angle range is an angle relative to the starting edge, the same applies below). When the angle range corresponding to the target region is 60 ° to 120 ° (60 ° in size), the position in the air conditioner operation space at one boundary of the detection range of the human body sensor is 30 ° to 60 ° (in this case, the position in the air conditioner operation space at the other boundary of the detection range of the human body sensor opposite to the boundary is 120 ° to 150 °). The detection angle range of the human body sensor is symmetrically distributed by taking the angle of the position of the human body sensor as a center, so that the position of the human body sensor is the position corresponding to the center angle of the detection angle range of the human body sensor. After the detection angle range of the human body sensor is determined, the position of the human body sensor can be obtained. The air conditioner controls the driving device to drive the human body sensor to rotate to a position corresponding to the detection angle range, so that the human body sensor can detect the human body in the region corresponding to the detection angle range, and the region corresponding to the detection angle range comprises the target region, so that the human body characteristics in the target region can be detected when the human body detection is carried out. For example, when the detection angle of the human body sensor is 90 °, and the angle range corresponding to the target area is 60 ° to 120 °, the position range of the human body sensor is 75 ° to 105 °, that is, the air conditioner control driving device drives the human body sensor to rotate to any angle within the range of 75 ° to 105 °.
Optionally, the air conditioner may control the driving device to drive the human body sensor to rotate to a central angle of an angle range corresponding to the target area, so that the human body sensor performs human body feature detection on an action space of the air conditioner by using the target area as a detection center. For example, when the angle range corresponding to the target area is 60 degrees to 120 degrees, the central angle of the angle range corresponding to the target area is 90 degrees, and the air conditioner controls the driving device to drive the human body sensor to rotate to a 90-degree position.
In practical use, a user may have a plurality of frequent moving areas, at this time, the target area includes a plurality of detection areas, when the target area includes a plurality of detection areas, the air conditioner determines whether the angle range of the target area exceeds the detection angle range of the human body sensor, and when the angle range of the target area does not exceed the detection angle range of the human body sensor, the position of the human body detection sensor can be determined according to any one of the above methods for adjusting the detection position of the human body sensor, which is not described herein again.
When the angle range of the target area exceeds the detection angle range of the human body sensor, the air conditioner can determine the sequence of each detection area according to the accumulated time length corresponding to each detection area contained in the target area, wherein the longer the accumulated time length is, the more the sequence is; and then, sequentially controlling the driving device to adjust the position of the human body sensor according to the detection sequence and each detection area so as to sequentially detect human body characteristics in each detection area according to the sequence. Specifically, the air conditioner determines each detection angle range corresponding to the human body sensor according to each detection area, and the area corresponding to each detection angle range comprises each detection area; and then controlling the driving device to drive the human body sensors to sequentially rotate to positions corresponding to the detection angle ranges according to the sequence so as to sequentially detect human body characteristics in the detection areas according to the sequence. And determining the detection angle ranges of the human body sensor and the corresponding positions of the detection angle ranges. Optionally, after the air conditioner controls the driving device to drive the human body sensor to rotate to the position corresponding to the detection area, the human body sensor is controlled to continue human body detection at the current position for a second preset time period, and when human body characteristics are detected within the second preset time period, the human body sensor is controlled to continue human body detection at the current position; and when the human body characteristics are detected within the second preset time, controlling the driving device to drive the human body sensor to rotate to the position corresponding to the next detection area so as to continuously detect the human body in the next detection area for the second preset time until the human body characteristics are detected.
Optionally, when the angle range of the target area exceeds the detection angle range of the human body sensor, the air conditioner may further determine the detection angle range of the human body sensor according to the detection area with the largest accumulated time length of the human body appearing in each detection area included in the target area, and then control the driving device to drive the human body sensor to rotate to the position corresponding to the detection angle range.
The air conditioner controls the human body sensor to detect human body characteristics of an action space in the target area, and when the human body characteristics are detected, the operation of the air conditioner can be controlled according to the detected human body characteristics, for example, operation parameters corresponding to the human body characteristics are acquired to control the operation of the air conditioner, or the position information of the human body is acquired, and a non-wind-sensing mode of the air conditioner is controlled according to the position information.
Further, when the air conditioner detects the human body characteristics, the time length of the human body appearing is recorded, and meanwhile, the time length of the human body appearing is stored in association with the target area so as to update the accumulated time length of the human body appearing corresponding to the target area.
In addition, in other embodiments of the present application, optionally, the target area may be set as an area that is the least frequently present for a user, and then the driving device is controlled to drive the human body sensor to avoid the target area, so that the human body sensor detects human body features in the air conditioner action space outside the target area. Specifically, the preset condition may be set to be minimum in each accumulated time, that is, when the accumulated time during which the human body appears is minimum in each accumulated time, and the accumulated time during which the human body appears meets the preset condition, the detection area corresponding to the accumulated time during which the human body appears is taken as a target area, and the driving device is controlled to drive the human body sensor to perform human body feature detection in the detection area outside the target area.
In this embodiment, a target area in a preset detection area is determined, where the target area is a detection area where the cumulative time length of the occurrence of the human body in a preset time length meets a preset condition, and the preset detection area includes a plurality of detection areas divided by an action space of the air conditioner; controlling the driving device according to the target area, and adjusting the detection position of the human body sensor so that the human body sensor detects human body characteristics in the target area; the detection range of the human body sensor can be adjusted according to the accumulated time length of the human body, so that the human body can be detected more easily, and the accuracy of human body detection is improved.
Further, referring to fig. 4, fig. 4 is a flowchart illustrating a second embodiment of the control method for human body detection according to the present invention, and based on the first embodiment, the step S10 includes:
step S11, acquiring a preset time period of the current time point;
step S12, determining a target area corresponding to the preset time period in a preset detection area, wherein the target area is a detection area in which the accumulated time length of the human body in the preset time period meets a preset condition, and the preset detection area comprises a plurality of detection areas divided by the action space of the air conditioner.
In practical use of the air conditioner, the positions of users in the action space of the air conditioner are different at different time periods, for example, the users are generally in the area of a bed at night, and the users generally move in the area of a desk, a sofa and the like at daytime; because the range of the user's activities is different at different time periods, the detection area of the human body sensor also needs to be adjusted correspondingly along with the time periods, so as to accurately detect the human body characteristics. Therefore, in this embodiment, the accumulated time length of the human body appearing in each detection area is recorded according to different time periods, and then the target area is determined according to the accumulated time length of the human body appearing in the time period of the current time point.
