Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The method and apparatus for controlling the antiglare mechanism of the present invention are described below with reference to fig. 1 to 4.
It should be noted that, the execution body of the anti-dazzle mechanism control method according to the embodiment of the present invention may be a processor, and of course, in other embodiments, the execution body may also be a server, and the specific type of the execution body is not limited herein. The antiglare mechanism control method according to the embodiment of the present invention will be described below by taking an execution main body as an example of a processor.
As shown in fig. 1, the method for controlling the anti-glare mechanism according to the embodiment of the present invention mainly includes step 110, step 120, and step 130.
It should be noted that the target room may be a room having a sun glare phenomenon, the target room may receive the irradiation of the outdoor sun light, and at least one light facade of the target room may receive the irradiation of the sun light.
When a plurality of illuminated facades exist in the target room and sunlight can be received and incident into the target room, the anti-glare mechanism can be controlled for each facade which can receive sunlight irradiation.
The target time is a time when the antiglare mechanism needs to be adjusted. The anti-glare mechanism may be a mechanism for adjusting the incidence of outdoor sunlight into a target room, such as a sun-shading article, a mechanism for adjusting the transmittance of light of window glass, or the like. The sun-shading articles can be window ornaments, such as curtains capable of moving in the horizontal direction, curtains capable of moving in the vertical direction, window blinds capable of adjusting the rotation angle and the like.
In some embodiments, longitude and latitude information of the illumination facade of the target room and time under the target time can be obtained in real time, and then the relative azimuth angle and elevation angle of the sun of the illumination facade of the target room can be calculated by combining the orientation azimuth angle, the inclination angle and the like of the facade of the target room.
In other embodiments, a photometer may also be employed to obtain parameters of the light facade of the target room related to the sun light. The photometer comprises a plurality of sensors and a data processing module. The sensor can comprise an illuminance sensor, a solar radiation sensor, a temperature and humidity sensor, a reserved external sensor interface and a positioning module.
The sensor can be installed on the rotary sensor bracket, so that the measuring position of the sensor can be conveniently adjusted, and related parameters can be measured at different angle positions, so that the measuring result is more accurate.
It can be appreciated that the illuminance sensor can be used to detect 360 degrees of all-round real-time illumination intensity, the solar radiation sensor can be used to detect 360 degrees of all-round real-time solar radiation intensity, and the temperature and humidity sensor can be used to measure outdoor environment's humiture condition in real time. The reserved external sensor interface can be connected with different sensors according to the detection requirement of the actual application environment so as to enrich the outdoor environment data detected by the photometer, such as a wind direction and wind speed sensor. The positioning module may be used to obtain information such as date, time, and position of the omnidirectional photometer, for example, the positioning module may be a GPS/beidou module.
In some embodiments, the photometer may be directly installed on the light facade of the target room, and the data processing module of the photometer may directly calculate the relative azimuth angle and elevation angle of the sun of the light facade of the target room at the target moment according to the data acquired by the positioning module of the photometer and the direction and the inclination angle of the light facade of the target room.
Under the condition, the relative azimuth angle and elevation angle of the sun can be obtained directly by obtaining the detection data of the photometer, and then the information such as the illumination intensity and the temperature of the target room can be obtained by combining the measurement data of each sensor, so that the reference information can be provided for the control of the air conditioner and the lamp in the target room.
Since sunlight in a target room is incident through a window on an illuminated facade, it is necessary to determine the relative positional relationship between personnel and the window in the target room. When the glare problem is considered, the observation angle value of the person in the target room to the window on the illumination outer elevation is considered, so that whether the sunlight entering the target room through the window directly irradiates human eyes or not can be conveniently determined, and the glare phenomenon is generated.
In some embodiments, the target person is a person in the target room who has anti-glare requirements.
In this case, the anti-glare request information transmitted by the target person through the terminal device may be received.
The terminal device may be a mobile phone, a tablet computer, a notebook computer, an intelligent wearable device, etc. of the target person, and the type of the terminal device is not limited herein.
The anti-glare request information may include attribute information of the target person, gesture information, and information that the target person turns on the anti-glare control. The attribute information of the target person may include height information of the target person and height position information of human eyes of the target person in different poses. The posture information may be information that the target person is kept standing and a state that the target person is seated on different furniture, such as a different chair and a sofa.
It can be understood that the target personnel can input and store the attribute information of the target personnel after measuring in advance so as to facilitate the direct call of the subsequent process.
For example, the target person transmits his or her own anti-glare request information through a mobile phone, wherein the posture information is that the target person sits in a chair. In this case, the transmitted attribute information may include height position information of human eyes when the target person sits on the chair.
In this case, the value of the observation angle of the window by the target person in the target room at the target time can be determined according to the position of the human eye and the size, inclination angle and shape of the window on the illuminated facade.
In some embodiments, determining the value of the angle of view of the window on the illuminated facade by the target person in the target room at the target time comprises the following process.
Specifically, a target person closest to the horizontal distance between the window and the plane of the window may be determined from the persons in the target room by at least two body sensors.
It should be noted that, when only one person is in the target room, only the antiglare requirement of the person needs to be considered. When a plurality of persons exist in the target room, the target person can be determined first from the plurality of persons.
In this embodiment, the closer a person in the target room is to the window, the larger the field of view the person sees outward through the window, and thus the more easily glare is perceived. Because the target person is the person closest to the horizontal distance between the window and the plane, if the anti-dazzle requirement of the target person is met, the anti-dazzle requirement of other people in the target room can also be met.
The human body sensor may be an ultrasonic sensor, a millimeter wave sensor, or the like.
When the human body sensor is used for detection, the positions of the human body sensors can be detected, and the distances of the human bodies relative to the window can be finally obtained according to the installation positions of the human body sensors and the positions of the windows.
In some embodiments, a body sensor may be installed in the frame of the window to facilitate data manipulation to reduce commissioning effort.
For example, considering that the sun is at a high position, persons in the target room do not look down from the lower edge of the window, millimeter wave body sensors may be installed on the upper, left and right three sides of the window frame of the window, and the distance and position of each person in the target room with respect to the window may be obtained from the detection data of the three millimeter wave body sensors.
On the basis, the human eye position of the target person can be further determined.
In some embodiments, the eye height of the target person may be determined first, and the eye height of the target person may be set according to an empirical value. For example, the human eye height may be any number between 1 meter and 1.5 meters.
In other embodiments, the position of the person and the eye height of the person may also be determined in an assisted manner from a monitoring picture taken by a camera mounted in the target room.
After the height of the eyes of the target person is determined, the positions of the eyes in the target room are determined by combining the positions of the target person, and then the positions of the eyes are obtained.
In this embodiment, detection by the human body sensor can improve detection efficiency and improve the intelligent control level of the product, reduce the use threshold of the user.
Based on the above, the observation angle value of the target person on the window on the illumination facade can be determined based on the human eye position of the target person and the size, the inclination angle and the shape of the illumination facade window of the target room. According to the positions of human eyes, the observation angle values of the human eyes of the target person to the positions of the window, such as the upper side, the left side and the right side, can be determined in sequence.
It is understood that when the direct irradiation direction of sunlight passes through the eyes of the target person, the eyes feel direct sunlight, and the glare phenomenon is easily felt.
In the present embodiment, the relative azimuth angle and elevation angle of the sunlight illuminating the outer face and the observation angle values of the target person at each position of the window are analyzed, so that the relative positional relationship between the direct sunlight illuminating direction and the eyes of the target person at the target time is determined.
For example, it may be determined that sunlight is directly irradiated into the human eye when some conditions are simultaneously satisfied. The above conditions include: the absolute elevation angle of the sun on the horizontal plane of the human eye is greater than or equal to zero (i.e. only during the daytime); the elevation angle of the projection sun is smaller than the angle range of the upper edge of the human eye window; the elevation angle of the projection sun is larger than the negative angle range of the angle range under the opposite window side of the human eye; the relative azimuth angle is smaller than the left angle of a human eye window; the relative azimuth angle is smaller than the angle at which the right edge is seen by the human eye.
And 130, controlling the window decoration of the target room to adjust the working state based on the relative position relation.
It can be understood that after determining the relative position relationship between the direct irradiation direction of sunlight and the eyes of the target person at the target moment, it can be determined whether the sunlight directly irradiates into the eyes of the target person in the current scene, thereby determining whether the target person can feel the glare phenomenon.
It is understood that the window ornament may be adjusted in the working state when it is determined whether the target person can feel the glare phenomenon based on the relative positional relationship.
For example, the position of the window covering may be adjusted to adjust the position of the window covering to the window for different types of window coverings to block sunlight directly from entering the human eye.
According to the anti-dazzle mechanism control method provided by the embodiment of the invention, through analyzing the illumination condition outside the target room and the observation angle value of the target person on the window, the relative position relation between the direct illumination direction and the human eyes of the target person can be determined, so that whether the target person experiences the glare phenomenon or not is judged, the window ornament can be adjusted to a proper working state under the condition that the target person in the target room experiences the glare, further, the sunlight is shielded, the direct illumination of the human eyes by the sunlight is avoided, the complete shielding of the sunlight is avoided, and the anti-dazzle control for indoor people under the condition that the sunlight utilization rate is improved is realized.
In some embodiments, controlling the window treatment adjustment operation state of the target room based on the relative positional relationship includes: under the condition that the direct irradiation direction of sunlight does not pass through the eyes of the target person, the window decoration is controlled to adjust the working state so as to reduce the sunlight shielding area of the window of the target room.
It is understood that in determining whether the direct irradiation direction of sunlight passes through the eyes of the target person, it is considered that no anti-glare mechanism for shielding the eye light, such as window ornaments, is provided on the window. If the glare phenomenon is not felt by the person directly detected, the existing window decoration on the window is directly controlled to adjust the working state so as to reduce the sunlight shielding area of the window of the target room and improve the utilization rate of sunlight.
For example, the position of the window shade may be adjusted to the edge position of the window, or the position angle of the window blinds may be adjusted so that sunlight may be radiated into the target room to a greater extent, thereby improving the utilization of sunlight by the target room.
In some embodiments, as shown in FIG. 2, step 130: controlling the window treatment adjustment operation state of the target room based on the relative positional relationship includes steps 131 and 132.
It will be appreciated that in the case where the direct irradiation direction of sunlight passes through the eyes of the target person, the target person may experience a glare phenomenon, and in this case, the glare phenomenon felt by the target object may be quantitatively evaluated.
In this embodiment, a unified glare value (UnifiedGlareRating, UGR) is used to measure a psychological parameter of subjective response of light emitted from a lighting device in a visual environment to discomfort caused by human eyes.
In some embodiments, the unified glare value may be determined based on a solar factor in the target room at the target time and a horizontal illuminance of the target room light facade.
The solar factor is the ratio between the indoor illuminance or brightness and the outdoor horizontal illuminance. For example, one or two reference points may be designated in the target room area, and the sunlight coefficient may be determined by measuring the reference points by a digital camera having a photosensitive function, and determining the ratio of the illuminance generated by receiving the sky diffuse light from the assumed and known brightness distribution directly or indirectly to the sky diffuse light illuminance generated by the sky hemisphere at the outdoor unobstructed horizontal plane at the same time.
In the process of UGR calculation, factors including sky brightness distribution, window size and orientation, glass transmittance, internal surface reflectivity, and operating state of the anti-glare mechanism are considered in consideration of calculation of window brightness and window background brightness. During the measurement, the solar factor calculation needs to be calculated every time step after sunrise.
In some embodiments, the illuminance of the reference point in the target room is first obtained by interpolating the stored solar coefficients with the sun position and sky state of the current time step to obtain the current solar coefficients, and then multiplying the current solar coefficients by the outdoor horizontal illuminance to finally obtain the unified glare value at the target time.
It will be appreciated that the sensitivity and acceptance of the glare phenomenon is not the same for different persons, and therefore, direct adjustment of the operating state of the window decoration when glare occurs does not necessarily allow maximum use of the sunlight.
And step 132, controlling the window decoration to adjust the working state under the condition that the unified glare value is larger than the first threshold value.
In this embodiment, the first threshold value may be set in advance, and the first threshold value is a unified glare value threshold value set in advance.
It will be appreciated that different first thresholds may be defined according to different target rooms and different moments in time. For example, the target room is a bedroom of Zhang san, the maximum unified glare values of Zhang san acceptable in different times of the day can be determined according to the acceptance degree of Zhang san to the glare phenomenon, and the maximum unified glare values are used as the first threshold value to be associated with the target room of Zhang san, so that the anti-glare mechanism of Zhang san can be controlled by adopting different first threshold values at different times.
In this embodiment, by setting the first threshold, whether the anti-glare requirement exists in the target room can be determined according to personal preferences of different target persons at different moments, and the window decoration article is controlled to adjust the working state only when the unified glare value is greater than the first threshold, so that sunlight can be utilized to the greatest extent possible while the anti-glare requirement of the persons is met.
In some embodiments, the window treatment comprises a window blind, and controlling the window treatment to adjust the operating state if the unified glare value is greater than a first threshold value comprises: and under the condition that the unified glare value is larger than a first threshold value, determining a target position angle of the window shutter for reflecting sunlight to the ceiling of the target room based on the direct irradiation direction of the sunlight at the target moment, and controlling the window shutter to rotate to the target position angle.
It will be appreciated that the direction of direct illumination of sunlight may be determined from the relative azimuth and elevation of the target room illuminating the facade sun at the target instant.
After the direct irradiation direction of sunlight is determined, the target position angle of the window shutter activity can be determined.
It should be noted that the type, size and installation mode of the window shutter all affect the determination of the target position angle. Calibration may be performed for a particular window shutter for each target room. After replacing other types of window blinds, the target position angle can be calibrated again.
In the embodiment, after the window shutter moves to the target position angle, sunlight can be reflected to the ceiling of the target room, so that the sunlight is prevented from directly irradiating human eyes, the sunlight shielded and reflected by the window shutter can be utilized to a certain extent, and the sunlight reflected illuminance in the target room is moderately increased.
In some embodiments, the window treatment comprises a window covering, and controlling the window treatment to adjust the operating state if the unified glare value is greater than a first threshold value comprises: under the condition that the unified glare value is larger than a first threshold value, determining a target position where the curtain shields sunlight with the direct irradiation direction passing through the eyes of the target person based on the direct irradiation direction of the sunlight at the target moment and the eye position information of the target person; and controlling the curtain to move to the target position.
It can be understood that the direct irradiation direction of sunlight can be determined according to the relative azimuth angle and elevation angle of the sunlight irradiating the outer elevation of the target room at the target moment, so that the sunlight irradiating a certain area of the outer elevation window in the target room can be determined to directly irradiate into human eyes.
On the basis, the movable range of the curtain is determined, and then the target position of the window area which shields direct sunlight to the greatest extent is determined, so that the curtain is controlled to move to the target position, and the possibility that indoor target personnel feel glare is reduced.
In some embodiments, after determining the unified glare value of the target person in the case that the direct irradiation direction of the sunlight passes through the human eye of the target person, the anti-glare mechanism control method of the embodiment of the invention further includes: and controlling the window ornament to adjust the working state to reduce the sunlight shielding area of the window of the target room under the condition that the unified glare value is smaller than or equal to the first threshold value.
It is understood that, although the direct irradiation direction of sunlight passes through the eyes of the target person at the current target moment, the target person does not feel the glare phenomenon. Therefore, the existing window decorations on the window can be directly controlled to adjust the working state so as to reduce the sunlight shielding area of the window of the target room and improve the utilization rate of sunlight.
For example, the position of the window shade may be adjusted to the edge position of the window, or the position angle of the window blinds may be adjusted so that sunlight may be radiated into the target room to a greater extent, thereby improving the utilization of sunlight by the target room.
