Abstract

PURPOSE:To cause all blinds to coincide with decision of fine weather and cloudy weather (or rain) by a method wherein a deciding circuit for fine weather and cloudy weather (or rain) through detection of a solar radiation amount is mounted independently, and a result decided in one spot is sent to each solar radiation control unit. CONSTITUTION:A solar radiation control unit 5 is provided with a function to calculate the irradiation angle of the sun from latitude, longitude, and a azimuth of a building and a data to regulate a slat angle to an optimum value, and a centralized control unit 2 is provided with a function to decide cloudy weather. Outputs therefrom are transmitted to each solar radiation unit through a signal line 3. This constitution enables reduction of a cost, and eliminates precise regulation of each blind.

[Means for Solving the Problems] The solar radiation control blind device according to the present invention has an independent circuit for determining whether it is sunny or cloudy (or rainy) based on solar radiation detection, makes a determination at one location, and connects each solar radiation control blind through a signal line. It is designed to be sent to the device.

[Operation] By making the circuit for determining whether it is sunny or cloudy (or rainy) independent in the present invention, it is possible to eliminate variations in the open/closed state due to differences in the determination criteria of each blind.

If a specific manual operation switch 16 is pressed when the power is turned on, the internal circuit test mode is entered, and internal circuits are sequentially checked, and after completion, the calendar setting mode is entered. If a predetermined switch is not pressed when the power is turned on, the automatic adjustment mode is entered and the processing shown in FIG. 5 is performed. First, after counting for 6 minutes, read the latitude and longitude from 17, the direction of the window from 18, and the year, month, day, hour, and minute from 22, and then calculate the sun direction and altitude with respect to the window surface. Read the voltage from the signal line 3 through the A/D converter 21, and if the voltage is V3 volts or V2 volts and after sunset (determined by the sun altitude being below 0°), the full open command is given, Vo volts or v1 pol 1-. If it is after sunset, a full open instruction is issued and the slat angle control section controls the slat angle to be fully opened or fully opened. If the signal line is not V, volt, or v0 volt, and it is before sunset, calculate the slat angle from the sun altitude and azimuth obtained earlier, and calculate the slat angle correction using the correction value read from the angle adjuster at 20. After doing this, use the slat angle control section to adjust the opening to achieve this angle. FIG. 6 is a flowchart of interrupt processing, and shows the manual operation switch 16.
After detecting the input of the mode changeover switch in , and switching to automatic mode, manual operation mode, or calendar setting mode, according to the input of the display changeover in 19, the display will display 1-angle 1 time or sun angle and direction. .
