  However, if the sensor for detecting the incident direction of sunlight is provided in the room like the solar sensor, the incident direction that can be detected is often limited, and the incident direction can be detected appropriately over a wide range. The problem that it is not possible arises. It is necessary to accurately detect the incident direction of sunlight in a time zone where there is a high demand for changing the operating state of the shutter curtain. The time zone in which the operation state of the shutter curtain is to be changed is, for example, in the range of 3 to 4 hours before and after the south / intermediate time when the sunlight is relatively strong.

  In addition, if the sensor is installed indoors, it is necessary to wire the signal line for transmitting the sensor output signal to the shutter device provided on the outdoor side of the building frame, which causes a problem that the wiring layout becomes complicated. .

FIG. 4 is a block diagram for explaining a configuration of a control system system of the shutter device according to the present embodiment.

  An opening 35 is formed in the housing 34, and a protective window 36 that transmits sunlight is provided so as to cover the opening 35. The first sensor 31 and the second sensor 32 are disposed in the housing 34. The housing 34 takes out an output signal from the signal processing unit 33 to the outside of the sensor unit 30, and supplies power to the sensor unit 30 (the first sensor 31, the second sensor 32, and the signal processing unit 33). A waterproof connector 37 is provided. The protective window 36 can be made of glass, polycarbonate, or the like.

  The first sensor 31 has an aperture 38 and a light receiving element 39. The aperture 38 is disposed on the inner surface of the housing 34 in the protective window 36 so as to correspond to the opening 35 of the housing 34. An opening 40 is formed in the aperture 38, and the sunlight incident area is limited by the opening 40. The light receiving element 39 has a light sensitive area 41 and detects a two-dimensional incident position on the light sensitive area 41 when it enters the light sensitive area 41. That is, the light receiving element 39 outputs a signal based on the position of sunlight that enters the photosensitive region 41 through the opening 40, that is, the incident position of sunlight. The light receiving element 39 is disposed so that the photosensitive region 41 faces the opening 40 formed in the aperture 38 in a state where the photosensitive region 41 is parallel to the aperture 38 and has a predetermined interval.

  In the present embodiment, a two-dimensional position detection element (two-dimensional PSD) is used as the light receiving element 39. The configuration of the two-dimensional position detection element is known (for example, Japanese Patent Laid-Open No. Hei 4-104019), and detailed description is omitted, but it has a photosensitive region 41 and four signal extraction electrodes. The two-dimensional position of the light incident on the photosensitive region 41 can be detected based on the output currents from the four signal extraction electrodes (anode electrodes). Each output current of the first sensor 31 (two-dimensional position detection element) is converted into a voltage signal by a current-voltage conversion unit 42 (for example, a current-voltage conversion amplifier configured by an operational amplifier or the like), and is sent to the signal processing unit 33. Entered.

  As the light receiving element 39, a multi-division photodiode (for example, a 4-division photodiode) can be used in addition to the two-dimensional position detection element. When a multi-division photodiode is used as the light receiving element 39, the two-dimensional position of the light incident on the photosensitive region of each photodiode is detected based on the output current from each photodiode.

  For example, a platinum thin film temperature sensor or a thermistor can be used as the second sensor 32. The output current of the second sensor 32 is converted into a voltage signal by a current-voltage conversion unit 43 configured by an operational amplifier and input to the signal processing unit 33.

  The signal processing unit 33 is configured by a microcomputer or the like, and calculates the incident direction (elevation angle) of sunlight and the amount of solar radiation based on the output from the first sensor 31 (voltage signal converted by the current-voltage conversion unit). And the signal regarding the incident direction of sunlight and the signal regarding the amount of solar radiation are output. A method for calculating the incident direction (elevation angle) of sunlight based on the incident position of sunlight is known (for example, Japanese Patent Laid-Open No. 4-104019 or Japanese Patent Laid-Open No. 6-123654). Omitted.

  The amount of solar radiation can be calculated by converting a signal obtained by adding up the voltage signals based on a predetermined characteristic. Here, the predetermined characteristic is, for example, a characteristic obtained from an actual measurement value of total irradiance by the CIE standard light source A (color temperature 2856K). In this case, the amount of solar radiation is expressed as illuminance. .

  The current-voltage conversion unit 42 is configured to switch the gain, and the gain is switched based on the switching signal from the signal processing unit 33. Specifically, in a time zone in which the incident angle of sunlight is low, the amount of solar radiation itself decreases and each output current from the first sensor 31 decreases, so the gain is switched to a large value. The output of the switching signal from the signal processing unit 33 can be performed based on the time by the built-in clock.

  The control unit 50 is a control unit that controls the driving unit 20 so as to change the operating state of the shutter curtain 10 (in the present embodiment, the angle of the slat 11), and is configured by a microcomputer or the like.
