δ = 0.006918−0.399912 cos θ ₀ +0.070257 sin θ ₀
−0.006758 cos (2θ ₀ ) +0.000907 sin (2θ ₀ )
−0.002697 cos (3θ ₀ ) +0.001480 sin (3θ ₀ )

Eq = 0.000075 + 0.001868 cos θ ₀ −0.032077 sin θ ₀
−0.014615 cos (2θ ₀ ) −0.040849 sin (2θ ₀ )

The hour angle H of the sun at an arbitrary time is obtained by the following equation (4) based on the Japan Standard Time JST.
H = (JST-12) π / 12
+ Longitude difference from the standard meridian (135-λ in Japan) + Eq (4)

The altitude angle α and the azimuth angle β of the sun are obtained by the following equations (5) and (6) based on the obtained solar declination δ, latitude φ, and hour angle H, respectively. The direction is from north to east, south, and west.
α = sin ⁻¹ (sinφsinδ + cosφcosδcosH) (5)
β = tan ⁻¹ (cosφcosδsinH / (sinφsinα−sinδ))

  Therefore, the calculation unit 43 includes the latitude and longitude information of the installation location of the shutter device S stored in the storage unit 40, the current date information generated by the calendar unit 41, and the clock unit 42. Current time information is acquired, and the altitude angle and azimuth angle of the sun at the current time are calculated according to the method described above.

Further, the signal processing unit 34a also outputs a signal related to the direction in which the frame body 1 is directed to the control unit 50 based on the output from the second sensor 32 (S115).

  From the latitude and longitude information of the installation location of the shutter device S, the current date information, and the current time information, the signal processing unit 34a calculates the altitude angle of the sun at the current time and the current time information as described above. The azimuth angle is calculated, and the calculation result is output to the control unit 50 as a signal related to the altitude angle and azimuth angle of the sun (S117).

  Further, the signal processing unit 34a obtains the outside air temperature from the third sensor 33, and outputs a signal related to the outside air temperature to the control unit 50 (S119).

  When the control unit 50 obtains a signal relating to the amount of solar radiation, a signal relating to the altitude angle and azimuth angle of the sun, a signal relating to the azimuth in which the frame 1 is directed, and a signal relating to the outside air temperature, The angle is calculated (S121). And the control part 50 outputs a control signal to the drive part 20 so that it may become the calculated angle of the slat 11 (S123). Thereby, the angle of the slat 11 is adjusted to a desired angle.

  As described above, according to the present embodiment, the calculation unit 43 has the latitude and longitude information stored in the storage unit 40, the date information generated by the calendar unit 41, and the time generated by the clock unit 42. Based on the information, the altitude angle and the azimuth angle of the sun are calculated, and the controller 50 detects the illuminance detected by the first sensor 31 and the azimuth detected by the second sensor 32 (the frame 1 is directed). And the driving unit is controlled to change the operating state of the shutter curtain 10 based on the altitude angle and the azimuth angle of the sun calculated by the calculating unit 43, so when installing the shutter device S Unlike the shutter device described in Patent Document 1, it is not necessary to set the position, orientation, etc. on the earth by operating each dip switch for each shutter device S.
