Description
Technical Field
The invention relates to the field of building sun shading, in particular to a control method and a control system of a shading device.
Background
With the improvement of living standard of people, the application of the sun-shading device on buildings is more common, the main purpose of the sun-shading device is to control solar heat energy, outdoor light and the like entering indoor space, for example, partial heat exchange can be realized through controlling the solar heat energy, and for example, under the condition that the heat exchange amount is small, the air conditioner can be omitted to be started. The brightness of the indoor space can be improved to a certain extent by controlling the outdoor light. If under the condition that the lighting is good and the lighting area is large, the light is controlled, the experience of glare and the like of personnel in the indoor space can be effectively prevented by reducing the entering of the light, and the brightness level of the indoor space can be effectively improved by increasing the entering of the light.
Taking the example of adjusting the light entering the indoor space by the related sunshade device, the conventional sunshade device usually adopts a single adjusting structure and has less related constraints in the adjusting process when adjusting the light, so that the adjusting scheme for the light has a great space for improvement.
Accordingly, there is a need in the art for a new solution to the above problems.
Disclosure of Invention
In view of this, the present invention provides a method and a system for controlling a light shielding device, which aim to optimize a brightness adjustment mechanism of an indoor space.
A first aspect of the present invention provides a control method of a shade apparatus including: the first shading unit comprises a light guide pipe, the light guide pipe is arranged on the top wall of the indoor space, and light of outdoor environment can reach the indoor space through the light guide pipe; and a second light shielding unit including a blade portion provided at a sidewall of the indoor space, the blade portion adjusting a posture thereof to adjust a flux of light of an outdoor environment entering the indoor space; the control method comprises the following steps: acquiring brightness data of the indoor space; judging whether the brightness of the indoor space needs to be adjusted or not according to the brightness data; and if so, at least adjusting the posture of the blade part.
With such an arrangement, communication with the outdoor environment through the first light shielding unit and the second light shielding unit can be achieved, and reasonable luminance of the indoor space can be configured.
With regard to the above control method, in one possible embodiment, the light guide is provided with an adjustment mechanism including a movable piece freely rotatably accommodated inside the light guide so as to adjust a flux of light entering an outdoor environment of the indoor space by adjusting a posture of the movable piece, the control method further including: acquiring external parameters related to light of an outdoor environment; and selectively adjusting the posture of the movable sheet at least according to the external parameters.
With this arrangement, the flux of light in the outdoor environment of the indoor space can be adjusted by two adjustment methods in cooperation.
It is understood that the specific form of the external parameter may be determined by those skilled in the art according to actual circumstances. As an example, the external parameters include one or more of season, air temperature, cloudy and sunny parameters, and the like.
With regard to the above control method, in a possible embodiment, the movable plate has a plurality of preset postures, and the "adjusting the posture of the movable plate" includes: the movable piece is caused to be in one of a plurality of preset postures.
By this arrangement a specific way of adjusting the light guide is given.
It is understood that the specific form of the preset gesture and the number of the gestures can be determined by those skilled in the art according to actual situations. As an example, the preset postures include a fully open state, a fully occluded state, a plurality of partially open states, and the like.
With regard to the above control method, in a possible embodiment, the "selectively adjusting the posture of the movable piece at least according to the external parameter" includes: acquiring a reference parameter; and selectively adjusting the posture of the movable sheet according to the external parameter and the reference parameter.
With such an arrangement, it is possible to seek to determine the attitude adjustment of the movable piece by introducing the reference parameter.
It can be understood that, on the premise of ensuring that the intervention of the reference parameter can optimize the judgment mechanism of the posture adjustment of the movable plate, a person skilled in the art can determine the source and the generation mode of the reference parameter according to the actual situation. For example, the reference parameter may be: parameters that can be directly obtained (such as lighting or not) related to the actual brightness of the indoor space; the parameters entered in relation to the person in which they are located (e.g. different persons differ in their sensitivity and requirements for brightness); a parameter that is set in advance in relation to an objective factor such as the current time period (e.g., preset to not open the light pipe after 17: 00); and the like.
For the above control method, in a possible implementation manner, the movable sheet is provided with a light hole.
With this arrangement, the light blocking by the movable piece and the light transmission by the light transmission hole in the movable piece can be achieved in cooperation with each other to achieve a better adjustment effect.
For example, in the case where the movable plate completely blocks the light guide, a small amount of light may still enter the indoor space due to the light-transmitting hole.
With regard to the above control method, in a possible implementation manner, the movable plates include a first movable plate and a second movable plate that are relatively rotatable, at least one movable plate is provided with the light-transmitting hole, and the "adjusting the posture of the movable plate" includes: and relatively rotating the first movable sheet and the second movable sheet to change the light transmission state of the light transmission hole through the relative rotation.
With such an arrangement, the light flux of the light guide can be further adjusted by adjusting the light transmission state of the light transmission hole.
For example, if the first movable plate and the second movable plate are of substantially the same, coaxial and superposed structures, the two movable plates are provided with the light holes, but the distribution modes of the light holes are different, so that different light-transmitting holes capable of effectively transmitting light can be combined on the premise that the two movable plates rotate relatively.
With regard to the above control method, in a possible embodiment, the brightness data includes first brightness data, the first brightness data is used for representing a situation that an outdoor environment transmits light to an indoor space at a position corresponding to the blade group, and the "determining whether the brightness of the indoor space needs to be adjusted according to the brightness data" includes: and judging whether the brightness of the indoor space needs to be adjusted or not according to the first brightness data.
With this arrangement, it is possible to draw a conclusion as to whether or not the luminance of the indoor space needs to be adjusted by referring to the local luminance.
Since the light transmission area of the blade assembly is significantly larger than that of the light guide, the adjustment mechanism can be better defined with reference to the local brightness.
In one possible embodiment, the determining whether the brightness of the indoor space needs to be adjusted according to the brightness data includes: detecting an object of an indoor space; and on the premise of detecting the object, judging whether the brightness of the indoor space needs to be adjusted or not according to the brightness data.
With this arrangement, effective brightness adjustment can be achieved.
With regard to the above control method, in one possible embodiment, the object is pupil data of a person of an indoor space.
By this arrangement, a specific form of the object is given. Only in the case of pupil data being collected, it is indicated that the person is in a light-facing pose. In such a case, it may be more necessary to adjust the brightness of the light of the indoor space.
It will be appreciated that since pupil data of a person in an indoor space is acquired, this requires that valid objects be interpreted as: the human pupil must be in a position to be able to be acquired. Such as may be interpreted as the pupil data of a person at the midpoint of the line connecting the two pupils of a person. Other similar ways of interpreting pupil data may be used where interpretation is reasonable, provided that such interpretation substantially accurately reflects the relationship between light and a person.
It will be appreciated that pupil data may be acquired for the entire subject or for a portion of the subject. Such as may be: the postures of the people in the indoor space comprise fixed postures and action postures, and only pupil data of the people in the action postures in the indoor space are collected, namely: screening the object by taking the posture of the person as a constraint condition; only when a person in the indoor space passes or is in a certain local target space, pupil data of the subject is acquired, namely: screening the object by taking the local space as a constraint condition; combining the human posture with the local space; and the like.

It will be understood by those skilled in the art that the present invention may be practiced without some of these specific details. In some instances, methods, procedures, components, and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present invention.
Fig. 1 is a schematic structural diagram of a shade apparatus according to an embodiment of the present invention. Referring to fig. 1, fig. 1 is a schematic structural diagram of a shading device according to an embodiment of the present invention. As shown in fig. 1, a front wall 1, a rear wall 2, other two walls (left wall, right wall) not shown, and a light-tight roof (top wall) enclose an indoor space. The indoor space is provided with a light shield mainly for regulating the flux of light entering the outdoor environment of the indoor space. The light shielding device includes a first light shielding unit that can adjust the flux of light with a small amplitude and a second light shielding unit that can adjust the flux of light with a large amplitude. Specifically, the method comprises the following steps:
1) a first light shielding unit:
the roof comprises two sloping parts, one of which 3 is provided with a light guide 4, the sloping part being substantially planar and the axis of the light guide 4 being substantially perpendicular to the sloping part.
It will be understood that one skilled in the art may flexibly modify one or more of the elements depending on the actual situation, such as the angled portions being non-planar, the angle between the light pipe 4 and the angled portions being other than 90 °, multiple light pipes 4 being provided on one angled portion, light pipes 4 being provided on both angled portions; and the like.
A diffuse transmission member, such as ground glass 52, is provided below the lower mouth of the light conduit 4, i.e. on the inside of the roof, near the light conduit. As in a specific example, a base body 51 as a mounting carrier for frosted glass 52 is mounted on the inner side of the roof, the base body is arranged in a horizontal direction, a mounting area is formed on the base body 51, and the frosted glass 52 is provided in the mounting area, for example, the mounting area is a substantially circular area.
It will be appreciated that the shape and size of the mounting area and the particular form of frosted glass mounted to the substrate may be determined by those skilled in the art based on the circumstances. Of course, the substrate could be omitted, such as mounting frosted glass directly to the existing structure of the roof. In addition, a structure having a diffuse reflection function other than ground glass may be employed.
In order to adjust the flux of light entering the indoor space through the light guide, in the light shielding device of the invention, an adjusting mechanism is provided for the light guide. In a possible embodiment, the adjusting mechanism essentially comprises a movable plate 61, which has approximately the same shape as the cross-sectional shape of the light guide but an area slightly smaller than the diameter of the light guide and can thus be accommodated freely inside the light guide, and which is provided with a rotating shaft 62 along its diameter, which is provided with a drive motor (hereinafter referred to as first drive motor). In this way, the first driving motor drives the rotating shaft to rotate to adjust the posture of the movable plate in the light guide pipe, so that the flux of the light of the outdoor environment entering the indoor space through the light guide pipe is adjusted.
2) A second light shielding unit:
the front side wall 1 is provided with a blade group 8, the blade group comprises six long blades which are longitudinally arranged, each long blade is provided with a rotating shaft, the long blades are rigidly connected with the corresponding rotating shaft or integrally formed, a driving motor (hereinafter referred to as a second driving motor) is arranged above the blade group, a power output shaft of the second driving motor is connected with a gear type conveyor belt, and the six long rotating shafts are all connected with the gear type conveyor belt in a meshed mode. In this way, the gear type conveyor belt rotates under the drive of the second drive motor, and the six long rotating shafts rotate synchronously with the rotation of the gear type conveyor belt, and the angles of the six long blades corresponding to the six long rotating shafts are adjusted simultaneously. On the premise that the angle of the long blade is adjusted, the flux of the light of the outdoor environment entering the indoor space is adjusted.
The light shading device based on the structure can optimize the brightness adjusting mechanism of the indoor space by adjusting the flux of the light of the outdoor environment entering the indoor space through the light guide pipe and the blade group by configuring the control part for the light shading device and adjusting the operation parameters of the first driving motor and the second driving motor in the light shading device. If the people in the indoor space need to prevent glare, the brightness of the indoor space can be adjusted.
If the control part mainly comprises a controller, a luminance meter and a pupil tracking sensor, the controller can correspondingly adjust the shading device by taking (or directly collecting) seasonal/cloudy data in weather, luminance data of light collected by the reference luminance meter and pupil data of an object in the indoor space collected by the pupil tracking sensor, so as to adjust the luminance of the indoor space.
In one possible embodiment, the luminance meter is used primarily to acquire luminance data of local light entering the indoor space through the light-transmitting region corresponding to the blade group, specifically, luminance data of local light entering the indoor space through the light-transmitting region with the light blocking device intervened for adjustment. In order to ensure that the brightness data collected by the brightness meter can reflect the brightness data of the local light more truly, the direction of the collected light of the brightness meter should capture the brightness data of the light in the light-transmitting area as much as possible, such as: although the luminance meter is disposed in the indoor space, the acquired luminance data of the light should reflect only the luminance data of the local light of the light-transmitting area as much as possible. In a possible embodiment, the light-transmitting area is formed at the middle position of the front wall according to the orientation of fig. 1, and the luminance meter may be installed at a position opposite to the light-transmitting area, such as the upper and right areas of the light-transmitting area. The pupil tracking sensor is mainly used to acquire the position of the pupil 7 of the subject in the indoor space, thereby obtaining pupil data of the subject.
Referring to fig. 2, fig. 2 is a flow chart illustrating a control method of a light shielding device according to an embodiment of the present invention. The control method of the invention can be adopted to flexibly adjust the flux of the light entering the outdoor environment of the indoor space. As shown in fig. 2, in a possible embodiment, the control method of the present invention mainly includes the following steps:
s201, acquiring external data related to light of an outdoor environment;
s203, determining the posture of the movable plate according to the external data;
in one possible embodiment, the movable plate inside the light pipe has three preset postures, in particular: a fully open state corresponding to a maximum flux of the light guide, a fully blocked state corresponding to a zero flux of the light guide and a partially open state corresponding to an angle of 45 ° between the movable plate and the axis of the light guide. In one possible embodiment, the external data related to the light of the outdoor environment includes three types of seasons, cloudy and sunny conditions, and the operating parameters of the first driving motor are controlled in combination with the current time period with reference to the season/cloudy and sunny/temperature data, so that the movable piece can be in one of three preset postures. Illustratively, the light conduit is switched between a partially open state and a fully blocked state by controlling the operating parameters of the first drive motor, such as 11:00-15:00 in summer, and the light conduit is brought to and in the fully open state by the operating parameters of the first drive motor during 10:00-17:00 in spring/autumn, assuming an air temperature below 25 ℃ and a clear day.
S205, on the premise that the object is detected in the local space of the indoor space, the posture of the blade group is selectively adjusted based on the luminance data detected by the luminance meter.
In one possible embodiment, pupil data of all objects that are in a certain local space in the indoor space are collected by a pupil tracking sensor. On the premise of detecting pupil data in a certain local space, selectively adjusting the operating parameters of a second driving motor according to the brightness data acquired by the brightness meter, so that the flux of light entering the outdoor environment of the indoor space is adjusted by changing the posture of the long blades in the blade group, and the brightness of the indoor space is adjusted based on the flux of the light.
On the premise that the posture of the long blade in the blade group needs to be adjusted, the specific adjustment amount is determined by referring to the position of the pupil data.
In a specific example, the illuminance l collected by the luminance meter reflects the local luminance data transmitted from the light-transmitting area to the indoor space. Assuming that a plurality of objects are detected in the current local space, the target angle associated with the adjustment amount is determined as follows. Specifically, the method comprises the following steps:
i) acquiring full data: it is assumed that an object currently located in a local space of an indoor space (a valid object capable of acquiring pupil data) includes a plurality of (i), and in this case, a pupilThe tracking sensor acquires the position of the pupils of all subjects. Let the angle between the connecting line of the pupil position of the ith object and the pupil tracking sensor and the horizontal plane be θi；
ii) selection of target included angle: in the case of complete data acquisition, the maximum value of the angles corresponding to all objects, i.e., max θ, is choseniSelect the target angle, and record it as thetamax。
Thus, the target angle θ can be referred tomaxThe operation parameters of the second driving motor are adjusted to further adjust the brightness data of the indoor space. Illustratively, the state of the shade device may be adjusted by:
if the illuminance L acquired by the luminance meter is greater than or equal to the preset illuminance L, the object in the indoor space is considered to be capable of obviously feeling the glare phenomenon, the controller can send a control signal capable of dimming the luminance to the second driving motor, and based on the control signal, the included angle a (the included angle of one side facing the outdoor environment) between the long blade and the horizontal plane in the blade group is increased to a>θmaxBased on this, the flux of light of the outdoor environment entering the indoor space through the light-transmitting area can be reduced, and the feeling of glare produced by the object in the indoor space can be significantly reduced;
if the illuminance L acquired by the luminance meter is less than the preset illuminance L, the object in the indoor space is considered not to obviously feel the glare phenomenon, at the moment, the controller does not need to send an instruction for adjusting the operation parameters of the second driving motor, and the included angle a between the long blade in the blade group and the horizontal plane is kept unchanged.
It can be seen that in the inventive control method, the flux of light entering the indoor space via the light guide is adjusted to a lesser extent, based on the acquired external parameters relating to the light of the outdoor environment; based on the collected luminance data of the indoor environment, the flux of light entering the indoor space through the light-transmitting region corresponding to the blade group is adjusted to a large extent. By the cooperation of the two adjustments, the flux of light entering the outdoor environment of the indoor space can be adjusted more flexibly.
It should be noted that, although the foregoing embodiments describe each step in a specific sequence, those skilled in the art may 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 may be executed simultaneously or in other sequences, and some steps or elements in the steps may be added, replaced or omitted, and such changes are within the protection scope of the present invention. Such as may be: the adjustment of the movable sheet and the adjustment of the blade group are changed or simultaneously carried out; the movable plate in the light guide pipe is structurally improved as follows: a light hole with smaller aperture is added on the movable sheet; and the like.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments, 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.
