Various types of sunlight tracking and daylighting devices have been proposed to solve such a problem, but there is a problem of how to easily introduce sunlight. For example, by rotating the reflection mirror to an appropriate angle,
The main body of the control device for introducing the sunlight reflected by the reflection mirror to the shaded part is generally installed in the underground electric room where the wiring is easy and inconspicuous. Since the shade area cannot be seen from the electric room in the basement, a telephone line is installed between the position where the shade area where sunlight should be introduced and the electric room where the control device main body is installed. There was an operator in each to remotely control the angle of the reflecting mirror via the telephone, but the angle adjustment work of the reflecting mirror is troublesome, and
There was a problem that it took time.

It is formed of an operation display unit 20 including an operation unit 20a for changing a shaded area and a display unit 20b for displaying an operation state. In the figure, a display device 21 is a large-scale demonstration display device made of a plasma display, and is provided, for example, in an entrance lobby. Also,
The operation indicator 22 has the same function as the operation indicator 20, and can be added freely.
You can check the change of the state of introduction of sunlight due to the rotation of, and perform the operation for demonstration. Needless to say, the operation display unit 20 may be detachable from the main body of the indoor block B so that it can be remotely controlled.

The operation of the embodiment will be described below. Now, the data storage unit 11 stores the altitude angle and the azimuth data of the sun for one year, which is determined based on the latitude data and the data of the time in the middle of the south, and is stored in the arithmetic unit 12 including a microcomputer. The current time data (“day” and “time” data) output from the clock part
The angle data of the reflection mirror 2 is calculated based on the correction data (data corresponding to the position of the shade portion where the sunlight should be introduced and the height of the building 1) transmitted from. The operation display unit 20 performs time data setting, latitude data setting, and south-central time correction data setting, and the calculating unit 12 calculates the altitude and azimuth of the sun based on these setting data by the following formula. It is like this.

sinβ ′ ＝ sinψsinδ ＋ cosψcosδcost sinα ′ ＝ cosδsint / cosβ ′ β ′: solar altitude (horizontal 0 °, zenith 90 °) α ′: sun direction (south central 0 °, east 90 °, west 90 °) T): Time angle (0 ° for south-central time, 15 ° for 1 hour) ψ: Latitude of set location δ: Declination (coordinate position of the sun on the celestial sphere) Sun calculated in this way The altitude and azimuth of the vehicle are displayed on the display unit 20a for displaying the operation status and the large display 21 for demonstration.

Next, the input operation of the correction data for introducing the sunlight into the predetermined shade is performed by the wireless transmission unit 15, and the operator who inputs the correction data is the wireless transmission unit 15
Standing in the shaded area while holding, operate the operation switch of the wireless transmission section 15 appropriately to change the altitude angle β and the azimuth angle α of the reflecting mirror 2, and as shown in FIG. The angle of the reflection mirror 2 is adjusted so that By pressing the standby switch in this state, the optimum altitude angle and azimuth angle of the reflecting mirror 2 at the current time are recognized by the arithmetic unit 12, and the arithmetic unit 12 calculates the altitude angle β, the azimuth angle α, and the current time. Corresponding correction data (offset value) is calculated based on the altitude angle and azimuth angle of the sun read from the data storage unit 11, and thereafter the altitude angle β and azimuth angle of the reflecting mirror 2 are calculated based on this correction data. α is calculated. In this case, the correction data transmitted from the wireless transmission unit 15 is received by the wireless reception unit 16 via the antenna 7 provided in the rooftop block A and input to the calculation unit 12. Since the antenna 7 is provided in the vicinity of the reflection mirror 2 that can be directly viewed from the shadow, the radio wave transmitted from the wireless transmission unit 15 can be reliably received. The correction data is set by the wireless transmission unit 15 when the sunlight tracking and lighting device is installed, or when the shade portion where the sunlight should be introduced is changed, and the setting work is completed. After that, the wireless receiver 16
And the antenna 7 is removed. Further, the correction data is data corresponding to the angle γ and is the height H of the building 1.
The correction data may be calculated by inputting the distance 1 from the building 1 in the shaded area where the sunlight should be introduced by the reflection mirror 2. In this way, the calculation unit 12
The altitude angle data and the azimuth angle data of the reflecting mirror 2 calculated by the above are respectively transmitted to the motor drive unit via the tracking control unit 13.
Drive motors 3a and 3b for driving the altitude axis drive section 4a and the azimuth axis drive section 4b are controlled by a drive signal input to the motor drive section 18 and output from the motor drive section 18. In this case, the actual altitude angle β and azimuth angle α of the rotating reflecting mirror 2 are calculated by the altitude angle detection unit 5a and the azimuth angle detection unit.
It is detected by 5b and fed back to the tracking control unit 13. In the tracking control unit 13, the reflecting mirror 2 is accurately moved to a predetermined position (sunlight is introduced to a predetermined shade portion) based on this feedback signal. It can be rotated to any position). In the embodiment, the altitude angle data and azimuth angle data calculation unit 12 outputs the data every minute, and the reflection mirror 2 is intermittently driven to save power. The reflection mirror 2 is returned to its original state during the sunset time when the sun is set, and is set in a standby state until the sun rises. Next, the wind speed detection signal output from the anemometer is the wind speed detection unit.
17 and the instantaneous wind speed detection unit 17a detects the instantaneous wind speed, and the average wind speed detection unit 17b detects the average wind speed, and the tracking control unit 13 detects the instantaneous wind speed and the average wind speed at predetermined levels. Reflection mirror 2 when the above
It is designed to be rotated and locked to a safe position that does not receive large wind pressure.

6 (a) shows the case where sunlight is introduced into the courtyard provided in the center of the building 1, and FIG. 6 (b) shows that the reflection mirror 2 is rotated 180 ° to the north side of the building 1. Shows the case where sunlight is introduced into the shaded area.

[Advantage of the Invention] As described above, the present invention tracks the sun so that the reflected light of the sunlight from the reflecting mirror installed on the roof of the building is introduced to a predetermined shade, and the altitude angle of the reflecting mirror is increased.

The tracking control unit that controls the rotation amount of the vehicle, the operation display unit that displays the operation status while inputting the latitude, time, and south-central time, and the correction data to the calculation unit based on the wireless signal from the outside. The wireless transmission unit and the operation display unit are provided separately, and a wireless transmission unit that transmits a wireless signal that gives the correction data to the calculation unit to the wireless reception unit is provided. Since the wireless signal is received from the wireless correction unit and the correction data is given from the wireless reception unit to the calculation unit, the construction should be performed while checking whether the reflected light of the sunlight is reflected by the reflection mirror in the shade where the sunlight should be introduced. Correction data for correcting the altitude angle and the azimuth angle of the reflecting mirror can be given to the calculation unit by operating the wireless transmission unit on site. As a result, it is possible to adjust the altitude angle and azimuth angle of the reflection mirror by yourself, depending on the construction site conditions such as the position of the shaded area and the height of the building. The adjustment work of is easy, and further, if the wireless transmitter and the wireless receiver are removed after the correction data is once set, it is possible to prevent the correction data from being erroneously changed. Of. In addition, the angle data for tracking the sun, the altitude angle and azimuth data of the sun for one year stored in the data storage unit, and the current time data indicating the current date and time from the clock unit,
Since the calculation is performed moment by moment based on the correction data provided by the wireless transmission unit and the wireless reception unit, the user can register the data about the altitude and azimuth of the sun, which is generally distributed, in the data storage unit. There is also an effect that it can be easily used just by placing it. In addition, an operation display unit is provided for inputting latitude, time, and south-central time and displaying operation status, and corrections are set from the wireless transmission unit according to the position of the shade and the height of the building. Since only the data is given, the wireless transmission part has only the function of adjusting the position of the reflection mirror, and there is also an advantage that it is not necessary to carry a large-sized device having unnecessary functions during construction work. .
