When the lower limit threshold and the upper limit threshold are set by self selection, the lower limit threshold is based on the lowest comfortable illumination intensity acceptable by the user and the value required to carry out light supplement when the light intensity is lower than the lowest comfortable illumination intensity acceptable by the user; the upper threshold is set to be the highest comfortable illumination intensity acceptable to the user, and the highest comfortable illumination intensity is set to be the value required for closing eyes or shading.
The intelligent automatic sun-shading action of the automatic sun-shading system for doors and windows of the embodiment is operated as follows:
the single subunit is used as an independent working unit in the daylighting glass, real-time illumination intensity data are collected by utilizing an illumination intensity sensor, numerical comparison is carried out on the basis of setting a lower limit threshold value and an upper limit threshold value in the previous step, and the roller shutter motor 5 and the shutter collecting motor 7 are driven by a controller according to the comparison value result so as to control the operation of the magnetic control shutter.
The method specifically comprises the following treatment levels:
a first level data processing hierarchy: comparing the illumination intensity values of the two sides of the sub-unit with the illumination intensity values of the two sides of the sub-unit (the two sides of the bottom of the sub-unit), after the data of the illumination intensity sensor of the two sides of the lowest of the sub-unit is processed and related actions are completed, sequentially processing the illumination intensity sensors of the two sides of the middle position and the illumination intensity sensors of the two sides of the lowest of the sub-unit (the two sides of the top of the sub-unit), and completing related actions. Under this processing hierarchy condition:
if the real-time illumination data obtained on the illumination intensity sensors 9 at two sides are smaller than the lower limit threshold value, the controller 1 is used for judging that the illumination intensity is insufficient, the daylighting glass is mainly in lighting demand at the present stage, at the moment, the magnetic control blind curtain sheet 3 is put flat (the magnetic control blind curtain sheet 3 is enabled to be horizontal, the magnetic control blind curtain sheet 3 is enabled to be folded and contracted by pulling the magnetic control blind curtain rope 4 through the curtain collecting motor 7 conveniently), and the magnetic control blind curtain sheet 3 after being put flat is upwards collected to the set height position of the previous illumination intensity sensor 9 by the curtain collecting motor 7.
If the real-time illumination data obtained by the illumination intensity sensors 9 on both sides are larger than the upper limit threshold value, the controller 1 judges that the illumination intensity is too strong to be too dazzling or the temperature in the building is greatly increased, and the corresponding daylighting glass is mainly required to be sunshaded at the present stage. Under the requirement condition, the magnetic control blind sheet 3 after being put down is put down to the setting height position of the next illumination intensity sensor 9 through the blind collecting motor 7, and the blind collecting motor 5 closes the magnetic control blind sheet 3 to carry out sun shading.
If one of the real-time illumination data obtained by one of the illumination intensity sensors 9 on both sides of the same group (hereinafter referred to as an illumination intensity sensor I) is located between the lower threshold and the upper threshold, entering a second data processing level, under the condition of the data processing level, the controller 1 determines that the lighting glass needs to be partially opened to allow for lighting and sunshade, and under the condition of the data processing level, the difficulty lies in determining and selecting the lighting and sunshade areas on the corresponding planes of the subunits:
a second level data processing hierarchy: the illumination intensity sensor I is judged in real time (by a clock unit built in the controller 1 or a network time synchronized after networking) and in position (preset in the controller 1 according to the azimuth of the building):
if the real-time is before 12 pm, whether the illumination intensity sensor I is at the eastern side or not is judged, if yes, the opening height position of the magnetic control blind curtain sheet 3 is controlled by the other illumination intensity sensor 9 (hereinafter referred to as illumination intensity sensor II), and the curtain angle opening of the magnetic control blind curtain sheet 3 is controlled by the illumination intensity sensor I under the condition that the magnetic control blind curtain sheet 3 is half-opened or full-opened; if not, the opposite is that the opening height position of the magnetic control blind curtain sheet 3 is controlled by the illumination intensity sensor I, and the curtain angle opening of the magnetic control blind curtain is controlled by the illumination intensity sensor II under the condition that the magnetic control blind curtain sheet 3 is half-opened or full-opened;
if the real-time is after 12 PM, whether the illumination intensity sensor is on the side close to the west is checked, if yes, the opening height position of the magnetic control blind curtain sheet 3 is controlled through the illumination intensity sensor II, and the curtain angle opening of the magnetic control blind curtain is controlled through the illumination intensity sensor I under the condition that the magnetic control blind curtain is half-opened or full-opened; if not, the opposite is that the opening height position of the magnetic control blind curtain sheet 3 is controlled by the illumination intensity sensor I, and the curtain angle opening of the magnetic control blind curtain is controlled by the illumination intensity sensor II under the condition that the magnetic control blind curtain is half-opened or full-opened;
when the opening height position of the magnetic control blind sheet 3 is controlled by the illumination intensity sensor 9:
if the real-time illumination data obtained by the illumination intensity sensor 9 is smaller than the lower limit threshold value, the magnetic control shutter sheet 3 is received at the position of the set height of the previous illumination intensity sensor 9 (for example, the illumination intensity sensor 9 is received at the position of the set plane from the position of the illumination intensity sensor 9 at the bottom of the subunit, or the illumination intensity sensor 9 is received at the position of the set plane from the position of the illumination intensity sensor 9 at the middle of the subunit), and at the moment, the daylighting glass shifts to the daylighting requirement on the basis of taking lighting and sunshade into account;
if the real-time illumination data obtained by the illumination intensity sensor is larger than the upper limit threshold value, the magnetic control shutter curtain is lowered to the setting height position of the next illumination intensity sensor (for example, the setting plane position of the illumination intensity sensor 9 at the middle position of the subunit is received from the setting plane position of the illumination intensity sensor 9 at the bottom of the subunit or the setting plane position of the illumination intensity sensor 9 at the top of the subunit is received from the setting plane position of the illumination intensity sensor 9 at the middle position of the subunit), and at the moment, the lighting glass shifts to the sun-shading requirement on the basis of taking lighting and sun-shading into account;
and if the real-time illumination data obtained by the illumination intensity sensor is positioned between the lower limit threshold value and the upper limit threshold value, the magnetic control shutter curtain is lowered to the middle position of the illumination intensity sensor and the next illumination intensity sensor. On this basis, be equivalent to, the lower hem of magnetic control blind has five to stop the some positions in the vertical direction of subunit, corresponds respectively and opens entirely, closes entirely, half open, 2/5 open and 4/5 open, this makes magnetic control blind more dynamic and the flexibility ratio better in the aperture, can cooperate the adjustment of the 3 curtain angle aperture of magnetic control blind piece on the magnetic control blind of rolling up curtain motor 5 to effectively improve the adaptability of door and window automatic sunshade system to illumination intensity in the application to further improve the comfort level under the illumination environment in the building.

the corresponding curtain angle opening ratio of the magnetic control blind curtain sheet is as follows:
wherein m is an upper threshold, n is a lower threshold, and x is a real-time measurement value of the illumination intensity sensor; when a is 0, the magnetic control shutter curtain sheet 3 of the magnetic control shutter curtain keeps 45 degrees and slopes to the outdoor closed state (considering that in the state, the magnetic control shutter curtain sheet 3 can prevent solar radiation from penetrating through glass to directly irradiate indoors, the effect of preventing the formation of a thermal polymerization effect and reducing the radiation energy consumption of an external window is achieved, namely the magnetic control shutter curtain sheet 3 is considered to be in the closed state in the state); when a is closer to 1, it means that the magnetic blind is closer to the fully open state (i.e., the magnetic blind sheet 3 remains horizontal); the corresponding a is the corresponding proportional angle after converting the 45-degree angle adjusting range of the magnetic control blind sheet 3 in a horizontal state and 45 degrees and sloping to the outside of the room into 100 parts.
