The light / dark threshold is a threshold for determining whether the outdoors is bright or dark, and is determined by the amount of power generation. It is conceivable that the brightness / darkness threshold value is set to a constant reference value or set based on the illumination state (illuminance) of the illuminator attached.

The structural features of the invention of (8) include a shutter composed of a plurality of slats, a slat drive unit that moves the slats so that the blind state can be corrected by the size of the opening between the adjacent slats, A blind shutter device installed in an opening of a building, having a control unit for driving the slat drive unit,
An illuminator indoors,
The control unit is an indoor lighting state acquisition unit that acquires the lighting state of the illuminator, an outdoor sunshine state acquisition unit that acquires an outdoor sunshine state, and the lighting state is a state using the illuminator. And a slat opening setting unit that sets a change opening to a closed opening when the outdoor sunshine condition is determined to be dark in the outdoors, and the opening of the slat is changed. The slat drive unit is driven so as to have an opening degree.

  The outdoor sunshine state can use a continuous value related to illuminance as it is, or can be binary information determined by whether or not a value related to illuminance exceeds a predetermined threshold value. As a method of acquiring the sunshine state, for example, using a system such as HEMS (Home Energy Management System), estimating the light and darkness and illuminance from the power generation amount of the solar power generation device, acquiring the region, date or time, This can be obtained by guessing the brightness or illuminance of the outdoors.

  The invention of (9) is that in the invention of (8), the indoor illuminance acquisition unit acquires the on / off or dimming state of the illuminator from the illuminator or a device that manages the illuminator.

  The invention of (10) is that in the invention of (8) or (9), the outdoor illuminance acquisition unit estimates the outdoor sunshine state from the area, date and time, or the amount of power generated by the solar power generation device.

  In the invention of (1), the amount of power generation is used to adjust the slat opening. The amount of power generation is acquired from the solar power generation device. Since the photovoltaic power generation device is installed on the roof (the roof) of a building, unlike an illuminometer installed indoors, it can provide information that is not affected by furniture or the like. In addition, since the solar cell panel of the solar power generation device has a large area, the amount of power generated is not affected by the illuminance of a narrow fixed place like an illuminance meter, and is not easily affected by the attachment of a shield or a small amount of dirt. Therefore, according to the invention of (1), since the illuminance outside the room can be estimated based on the amount of power generated by the photovoltaic power generation apparatus, it is difficult to place the room indoors or is affected by indoor furniture. The slat opening can be adjusted appropriately without installing an illuminance meter. The power generation amount can be obtained directly or indirectly from the solar power generation device. As an indirect acquisition method, for example, there is a method through a system such as HEMS (Home Energy Management System). In the case of indirectly acquiring the power generation amount, it is preferable to obtain a past power generation amount close to the present time.

  In the invention of (2), based on the power generation amount of the photovoltaic power generation apparatus, it is determined whether it is sunny or cloudy with a threshold value, and the slat opening is set to two openings, a sunny mode and a cloudy mode. Therefore, if the threshold value can be set to an appropriate value, the slat opening can be adjusted appropriately.

  The invention of (3) includes a storage unit that stores at least one of the region, date, and time, the acquired power generation amount, the slat opening degree, and / or the threshold value. Since the amount of power generation changes depending on the region, date, or time, the region, season, or time can be adjusted by correcting or changing at least one of the threshold value, sunny mode, or cloudy mode based on these. Can be adjusted to a comfortable slat opening degree.

  In invention of (4), it has a mode change switch which switches the slat opening degree adjusted to fine mode or cloudy mode. The control unit includes a threshold value correcting unit that corrects the threshold value based on the power generation amount when the sunny mode and the cloudy mode are changed by the mode change switch. Therefore, according to the invention of (4), the threshold value can be corrected in order to obtain a slat opening degree according to the place where the blind shutter device is installed and the preference of the user.

  In the invention of (5), the power generation amount acquired by the storage unit and the slat opening at the time of the power generation amount are stored. The control unit includes a storage slat opening correction unit that corrects the slat opening of the power generation amount stored in the storage unit when the slat opening is manually changed. Therefore, according to the invention of (5), the slat opening corresponding to the amount of power generation can be corrected as appropriate, so that it can be adjusted to a more comfortable slat opening.

  In the invention of (6), the slat opening degree of the slats can be adjusted in consideration of not only the power generation amount but also the lighting state of the indoor lighting. Therefore, according to the invention of (6), when the interior is brighter than the outdoors, it is possible to perform control such as adjusting the slat opening of the slats so as to make it difficult to see the interior from the outdoors.

  According to the invention of (7), whether the outdoor is bright or not is judged based on the light / dark threshold, and when the outdoor is dark and indoor lighting is on, the slat opening of the slat is set to the closed opening By doing so, it is possible to make the slat opening difficult to see indoors from the outside.

  According to the invention of (8), the indoor lighting state and the outdoor sunshine state are acquired, and when it is determined that the indoor is brighter than the outdoor, the slat opening of the slat is adjusted to the closed opening. Thus, it is possible to make the slat opening difficult to see indoors from the outside.

  According to the invention of (9), the indoor lighting state can be acquired directly from the illuminator or from a device that manages the illuminator, for example, HEMS.

  In the invention of (10), the outdoor sunshine condition can be estimated not only from direct brightness information but also from the region, date and time, or from the power generation amount of the solar power generation device. Therefore, according to the invention of (10), it is possible to acquire the sunshine state more accurately than the illuminance affected by the illuminance in a narrow range, furniture, buildings or deposits as in the illuminometer.

  A representative embodiment of the present invention will be described with reference to FIGS. The blind shutter device according to the present embodiment is attached to an opening (such as a window) of a building including a solar power generation device. A solar power generation device is a device that can be attached to the roof or roof of a building for the purpose of using the obtained power as the power of the building. As shown in FIG. 1, for example, the blind shutter device 10 is attached to a window 93 of a building 9 in which a solar battery panel 92 of a solar power generation device is attached to a roof 91 of the building 9.

  The blind shutter device 10 used in each embodiment includes a motor 11, a winding shaft 12 that is rotationally driven by the motor 11, two guide rail portions 15 that run in parallel in the vertical direction, and a guide rail portion. 15, a shutter 13 that is moved up and down along 15 and opened and closed along with the lifting, a storage box 16 that stores the motor 11 and the winding shaft 12, and a control unit 2 </ b> A. The control unit 2A is built in the storage box 16, for example. The shutter 13 is composed of a seat plate 17 located at the lower end and a large number of slats 18 constituting a portion above the seat plate 17. The slats 18 are extended horizontally, and a plurality of slats 18 are arranged in parallel in the vertical direction. The blind shutter device 10 includes a shutter usage mode in which the slat 18 is wound around the winding shaft 12 and the window 93 is directly exposed to the outside, and a blind usage mode in which each slat 18 rotates to use the slat 18 as a blind. And can be used properly.

  When the slat 18 is used as a shutter, the motor 11 rewinds the shutter 13 wound around the winding shaft 12 and the winding direction (arrow Y1 direction) where the shutter 13 is wound around the winding shaft 12. It is possible to rotate in each direction (arrow Y2 direction). The shutter 13 is raised by rotation in one direction of the motor 11 and lowered by rotation in the other direction of the motor 11.

  When the slats 18 are used as blinds, the slats 18 are moved between the slats 18 from the fully closed state (FIG. 2) with no gaps in the vertical direction by driving the motor 11 (or another driving device). It can be rotated to a blind state (FIG. 3). Each slat 18 is rotated by a predetermined angle, and the opening degree (hereinafter referred to as “slat opening degree”) can be adjusted. The predetermined angle can be appropriately selected and set such as 5 degrees, 10 degrees, 15 degrees, and 20 degrees.

  A controller (not shown) is used to wind up and rewind the shutter 13 and to use the slat 18 as a blind. The controller outputs information (electrical signal) necessary for the operation input to the control unit 2A, and outputs necessary instructions (electrical signal) to each component based on the information received by the control unit 2A. When a display panel or a lamp is lit on the controller, the control unit 2A displays whether a control state or an abnormality has occurred. The controller and the control unit 2A may be wired or wireless as long as they can transmit and receive electrical signals, and the controller is disposed inside the building. In addition, when the blind shutter device 10 is attached to each opening 93 for one building, it is also possible to control all the blind shutter devices 10 with one controller in the vicinity of each opening 93.

(Embodiment 1)
As shown in FIG. 1, the control unit 2A used in the blind shutter device 10 according to the first embodiment includes a slat drive unit 21, a power generation amount acquisition unit 22, a slat control state acquisition unit 23, and a slat opening setting unit 24. Prepare. The slat drive unit 21 can rotate the slat 18 to the input opening degree by the motor 11 described above. The power generation amount acquisition unit 22 can acquire the power generation amount of the solar power generation device. As the power generation amount, the power generation amount at the time of acquiring the power generation amount can be used as it is, or the total amount (or time average) of the power generation amount in a predetermined time can be used. As a power generation amount acquisition destination, it is desirable to be able to acquire the current power generation amount at or near the present time directly from the solar power generation device or from a HEMS (Home Energy Management System) controlled by the solar power generation device.

  The slat control state acquisition unit 23 acquires a state of whether the slat 18 is controlled based on the power generation amount or not controlled based on the power generation amount. The blind shutter device 10 used in the present embodiment is in a state where the slat 18 is not controlled by the power generation amount when the slat 18 is rotated to the desired slat opening degree by directly operating with the above-described controller. . It should be noted that the controller can be used to switch between the case where the slat 18 is automatically controlled by the amount of power generation and the case where the slat 18 is not.

  The slat opening setting unit 24 sets the changed opening to the sunny mode or the cloudy mode, and outputs the changed opening to the slat driving unit 21. The slat opening setting unit 24 sets the changed opening to the clear mode when the power generation amount exceeds the power generation threshold value, and to the cloudy mode otherwise. The power generation amount threshold value and the slat opening degree in the two modes are preset as initial values. Note that the slat opening degree of the two modes is narrower in the clear mode than in the cloudy mode, for example.

  Next, the control content executed by the control unit 2A will be described with reference to the flowchart shown in FIG. The control content executed by the control unit 2A is not limited to the flowchart shown in FIG. 4, but is merely an example.

  First, the control unit 2A acquires the power generation amount by the power generation amount acquisition unit 22 (step S21). Next, the control state as to whether or not the slat 18 is controlled by the power generation amount is acquired by the slat control state acquisition unit 23. If the slat 18 is controlled by the power generation amount, step S23 is executed and is not controlled by the power generation amount. In this case, step S24 is executed (step S22). In step S24, the state not controlled by the power generation amount is maintained, and the control shown in this flowchart is ended. In step S23, it is compared whether or not the power generation amount acquired in step S21 is larger than the power generation amount threshold value. If so, step S25 is executed, and if not, step S26 is executed. In step S25, the slat opening setting unit 24 sets the changed opening to the clear mode, and the slat driving unit 21 corrects the slat opening of the slat 18 to the changed opening. In step S26, the changed opening is set to the cloudy mode by the slat opening setting unit 24, and the slat opening of the slat 18 is adjusted to the changed opening by the slat driving unit 21. After executing step S25 or step S26, the controller 2A ends the control shown in this flowchart.

  The control unit 2A can execute the control shown in this flowchart when (1) it is periodically executed and (2) the controller is operated to intentionally control the amount of power generated. In the case of (1), it is executed every certain time, for example, every 30 minutes, every hour, every few hours. Alternatively, a flow may be considered in which step S21 is periodically executed and the acquired power generation amount is executed when the power generation amount reverses the sunny mode and the cloudy mode.

  The amount of power generation used by the blind shutter device 10 of the present embodiment to adjust the slat opening is obtained from the solar power generation device. Since the solar power generation device is installed on the roof 91 of the building 9, it is not affected by furniture or the like like an illuminometer installed indoors. In addition, since the solar panel 92 has a large area, the amount of power generated can be as follows: illuminance at a certain place like an illuminance meter, inaccurate illuminance due to a shielding object, or illuminance with dirt attached. Insensitive to shielding. Therefore, according to the blind shutter device 10 of the present embodiment, the outdoor illuminance (sunny or cloudy) can be estimated based on the amount of power generated by the solar power generation device, so that it is not affected by indoor furniture or the like. In addition, the slat opening can be adjusted appropriately.

(Embodiment 2)
As shown in FIGS. 5 and 6, the blind shutter device 10 according to the second embodiment has the same configuration and operational effects as the blind shutter device 10 according to the first embodiment. Below, it demonstrates focusing on a different structure.

  As shown in FIG. 5, the control unit 2B used in the blind shutter device 10 according to the second embodiment stores a slat drive unit 21, a power generation amount acquisition unit 22, a slat control state acquisition unit 23, a slat opening setting unit 24, and a storage. Part 25. Each of the slat drive unit 21, the power generation amount acquisition unit 22, the slat control state acquisition unit 23, and the slat opening setting unit 24 includes a slat drive unit 21 and a power generation amount of the control unit 2A used in the blind shutter device 10 of the first embodiment. This corresponds to the acquisition unit 22, the slat control state acquisition unit 23, and the slat opening setting unit 24, respectively.

  Among the flowcharts executed by the control unit 2B, steps S21 to 26 are the same as the flowchart executed by the control unit 2A used in the blind shutter device 10 of the first embodiment, and thus the description thereof is omitted. After executing step S25 or step S26, the control unit 2B acquires the region, date, and current time, and stores the power generation amount, power generation threshold value, and slat opening together with the region, date, and time in the storage unit 25. (Step S27), the control shown in this flowchart is terminated.

  The controller 2B can adjust the power generation amount threshold value and the slat opening degree of the two modes based on the stored information (data). The control unit 2B stores the power generation amount threshold value and the slat opening degree of the two modes in the storage unit 25, and sets the power generation amount threshold value according to the season for each region from the region and date, It can be used to change the power generation threshold value. For example, during the daytime during the summer, the slat opening in the sunny mode is smaller than in the cloudy mode during the daytime to block sunlight from entering the indoors at an opening that allows the wind to pass. The sunny mode is to make the slat opening larger than the cloudy mode. It can be adjusted by taking sunlight into the room to make it warm, and when it is cloudy, adjust the slat opening to a little for ventilation while heating is used indoors. Therefore, the sunny mode and the cloudy mode do not necessarily have the same slat opening, and can be set based on information stored in the storage unit 25.

  The information stored in the storage unit 25 can be taken out before and after step S21 in the flowchart of FIG. 6, for example. The control unit 2B acquires the region, date, and time, and acquires the power generation amount threshold value and the slat opening degree related to the information from the storage unit 25. Then, the power generation amount threshold value used in step 23 can be set to the power generation amount threshold value acquired from the storage unit 25, the sunny mode, or the cloudy mode. In addition, when there is not enough information stored in the storage unit 25, a value set as an initial value may be used.

  Furthermore, by having the storage unit 25, it is possible to correct the stored information, and to finely set, learn, and correct information according to the region for each date and time.

  According to the blind shutter device 10 of the second embodiment, it is possible to store and learn the power generation amount that changes depending on the region, date, or time. Then, based on the stored information, it is possible to set, change, or correct at least one of the power generation threshold value, sunny mode or cloudy mode, so that more preferable and more comfortable slat opening is possible. The slat 18 can be adjusted each time. In addition, by storing the power generation amount in the storage unit 25, the slat opening of the slat 18 can be adjusted according to the region, date, or time even in the case of a failure in which the power generation amount cannot be acquired.

The mode change switch 19 is arranged as one of the switches of the controller described above, for example. The mode change switch 19 is a switch for switching the slat opening degree of the slat 18 adjusted to the sunny mode or the cloudy mode. When the mode change switch 19 is pressed, the slat opening degree of the slat 18 is changed to the cloudy mode in the clear mode, and the slat opening degree is changed to the cloudy mode in the cloudy mode.

  The control unit 2C includes a slat drive unit 21, a power generation amount acquisition unit 22, a slat control state acquisition unit 23, a slat opening setting unit 24, and a threshold value correction unit 26.

This corresponds to the acquisition unit 22, the slat control state acquisition unit 23, and the slat opening setting unit 24, respectively. The threshold value correction unit 26 corrects the power generation amount threshold value based on the power generation amount acquired by the power generation amount acquisition unit 22 when the slat opening degree of the slat 18 is changed by the mode change switch 19. The threshold correction unit 26 has specifications such as correcting the power generation threshold value based on the power generation amount when the mode change switch 19 is used not only once but also several times. Conceivable. As a method for correcting the power generation amount threshold value, the power generation amount when the mode change switch 19 is used is directly used as the power generation amount threshold value, or the power generation amount for a plurality of times when the mode change switch 19 is used. The average value may be used as a power generation amount threshold value, or the average value of the power generation amount and the power generation amount threshold value may be used as a new power generation amount threshold value.

  Next, the control content executed by the control unit 2C will be described with reference to the flowchart shown in FIG. The control content executed by the control unit 2C is not limited to the flowchart shown in FIG. 8, but is merely an example.

(Embodiment 4)
As shown in FIGS. 9 and 10, the blind shutter device 10 according to the fourth embodiment has the same configuration and operational effects as the blind shutter device 10 according to the first embodiment. Below, it demonstrates focusing on a different structure.

  As shown in FIG. 9, the blind shutter device 10 according to the fourth embodiment includes a slat opening changing operation unit 14 in addition to the configuration of the blind shutter device 10 according to the first embodiment. The slat opening changing operation unit 14 is arranged as one of the switches of the controller described above, for example. The slat opening changing operation unit 14 is one of switches that manually change the opening of the slat 18, not only when the blind shutter device 10 is controlled based on the generated power. Each time the slat opening changing operation unit 14 is pressed, the slat 18 rotates 15 degrees (the rotation width can be changed). When the slat 18 rotates in an opening direction between a substantially vertical slat opening of 0 degrees and a substantially horizontal slat opening of 90 degrees and reaches approximately 90 degrees, the slat 18 rotates in a closing direction and approximately 0 degrees. If it reaches, it will rotate in the opening direction. Note that the slat opening changing operation unit 14 may be two instead of one, and may be an open switch that rotates one in the opening direction and a closed switch that rotates the other in the closing direction.

Each corresponds to the acquisition unit 23. The slat opening degree setting unit 27 sets one of the plurality of slat opening degrees as the changed opening degree based on the plurality of power generation amount threshold values. For example, when the power generation amount is larger than the first power generation amount threshold value, the first opening, when the power generation amount is less than the first power generation amount threshold value and larger than the second power generation amount threshold value, the second opening degree, second If the power generation amount threshold value is less than the third power generation amount threshold value and less than the third power generation amount threshold value, the change opening degree is set to the fourth opening degree.

The storage slat opening correction unit 29 corrects the slat opening corresponding to the power generation amount stored in the storage unit 28 when the slat opening of the slat 18 is changed by the slat opening changing operation unit 14. The correction of the slat opening is performed when the slat opening changing operation unit 14 is used several times while the blind shutter device 10 is controlled by the power generation amount. It stores that one of the degrees has been changed, and corrects the slat opening degree for the power generation amount threshold value repeated a predetermined number of times.
