  Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a power generation blind device according to an embodiment of the present invention. In addition, the dotted line arrow of FIG. 1 shows the flow of electric power, and the solid line arrow shows the flow of information.

  A power generation blind device 10 according to an embodiment of the present invention includes a blind portion 12, which blinds plate-shaped sunlight as shown in FIGS. 2 (A) and 2 (B). A plurality of light shielding plates (hereinafter referred to as slats 14). Each slat 14 is rotatably provided. That is, each slat 14 is capable of adjusting the angle with respect to sunlight. For example, as shown in FIG. 2 (A), the slat 14 shields light from a state where light is collected indoors as shown in FIG. 2 (B). It is possible to rotate up to.

  The slat 14 is rotated by driving the motor 16, and the angle of the slat 14 is adjusted by driving the motor.

  Further, solar cells 18 are provided on both surfaces of the slat 14, and power is generated when light enters the solar cells 18.

  The motor 16 is connected to the control circuit 20, and the angle of the slat 14 is adjusted by the control circuit 20 controlling the drive of the motor 16. The control circuit 20 can detect the angle of the slat 14 from the driving amount of the motor 16 or the like.

  In addition, an operation panel 22, a sunlight sensor 24, a wattmeter 26, and a power supply control unit 28 are connected to the control circuit 20.

  The operation panel 22 is capable of various settings of the power generation blind device 10 and includes a monitor for displaying various settings, operation keys for performing various settings, and the like. For example, the operation panel 22 can select and set a plurality of modes provided in the power generation blind device 10 by operating an operation key or the like.

  The sunlight sensor 24 is provided outside the blind portion 12, and detects sunlight illuminance, direction, season, weather, and the like by detecting sunlight, outputs the detection result to the control circuit 20, and outputs power. The total 26 detects the amount of power generated by the solar cell 18 provided in the slat 14 and outputs the detection result to the control circuit 20.

  The power supply control unit 28 is connected to the motor 16, the solar battery 18, the charging device 30, the electric device 32, and the power supply 34, and controls the flow of power.

  For example, the power supply control unit 28 supplies the generated power of the solar cell 18 to the motor 16 to drive the slats 14 or supplies the generated power (surplus) of the solar cell 18 to the charging device 30 for charging. The power generated by the solar battery 18 is supplied to an electric device 32 such as a lighting device other than the power generation blind device 10, or the commercial power is supplied from the power source 34 to the motor 16. Each power flow is switched in accordance with an instruction from the control circuit 20. Specifically, when power supply to the electric device 32 is necessary, the generated power of the solar cell 18 is supplied, and when the generated power is insufficient, commercial power is supplied from the power source 34. When the charging device 30 is not fully charged, the power generated by the solar battery 18 is charged into the charging device 30 and supplied to the electrical device 32 and the like.

  The control circuit 20 adjusts the angle of the slat 14 by controlling the driving of the motor 16 according to the selected mode when one of the plurality of modes is selected by the operation panel 22. To do. As a plurality of modes, in this embodiment, a lighting priority mode, a power generation priority mode, a normal mode, and a crime prevention mode are provided, and each mode can be selected by the operation panel 22.

  Here, the above-described plurality of modes (lighting priority mode, power generation priority mode, normal mode, security mode, etc.) will be described in detail.

  First, when the daylighting priority mode is set by the operation panel 22, as shown in FIG. 3A, the drive of the motor 16 is controlled by the control circuit 20 so that light enters the room, and the slats are controlled. The angle of 14 is adjusted. That is, when the daylighting priority mode is selected, the angle of the slat 14 is adjusted so that the daylighting priority is obtained following the solar radiation. Specifically, the control circuit 20 stores in advance the angle of the slat 14 in which light is preferentially incident in the room corresponding to the illuminance and the solar radiation angle, and detects sunlight by the sunlight sensor 24. The illuminance is detected and the current solar radiation angle is estimated, and the angle of the slat 14 is adjusted by driving the motor 16 so that the pre-stored daylighting is given priority corresponding to the detected illuminance and the estimated solar radiation angle. To do. For example, as shown in FIG. 3A, the slat 14 is adjusted to an angle at which solar radiation is reflected on the surface of the slat 14 and is incident on the room.

  Further, when the power generation priority mode is selected by the operation panel 22, the power generation amount of the solar cell 18 is detected by the wattmeter 26 while adjusting the angle of the slat 14, and the generated power is increased to the angle of the slat 14. Thus, the drive of the motor 16 is controlled by the control circuit 20. Specifically, the angle of the slat 14 is adjusted by controlling the drive of the motor 16 so that the amount of power is maximized by scanning the amount of power while adjusting the angle of the slat 14. Thereby, power generation by the solar cell 18 can be efficiently performed and power generation can be prioritized.

  When the normal mode is selected, as shown in FIG. 3B, the solar radiation is sequentially reflected on the front surface side of the slat 14 and the back surface side of the upper slat 14 to enter the room. That is, when the normal mode is selected, the angle of the slat 14 is adjusted so as to obtain predetermined lighting and power generation following the solar radiation. Specifically, the control circuit 20 stores in advance the angle at which predetermined lighting and power generation are obtained corresponding to the illuminance and the solar radiation angle, and detects the illuminance by detecting sunlight with the sunlight sensor 24. Then, the current solar radiation angle is estimated, and the motor 16 is driven to adjust the angle of the slat 14 so as to obtain a predetermined lighting and power generation stored in advance corresponding to the detected illuminance and the estimated solar radiation angle. As an angle for obtaining predetermined lighting and power generation, for example, as shown in FIG. 3B, the solar radiation is reflected on the surface of the slat 14, and the reflected light is reflected on the back surface of the upper slat 14, and then the room is indoors. The slat 14 is adjusted to the incident angle.

  When the crime prevention mode is selected by the operation panel 22, the drive of the motor 16 is controlled by the control circuit 20 so as to fully close the slats 14, as shown in FIG. This makes it impossible to visually check the room from the outside, and thus security can be emphasized. In this case, since sunlight is incident on the front surface side of the slat 14 and light such as indoor lighting is incident on the rear surface side, the solar cells 18 on the front and back surfaces of the slat 14 can generate power.

  In the present embodiment, when each of the above modes is not selected on the operation panel 22, the angle of the slat 14 can be manually adjusted by operating the operation panel 22.

  Next, processing performed in the control circuit 20 of the power generation blind device 10 according to the embodiment of the present invention configured as described above will be described in detail. FIG. 4 is a flowchart showing an example of the flow of processing performed by the control circuit 20 of the power generation blind device 10 according to the embodiment of the present invention.

  First, in step 100, the state of the slat 14 is detected, and the process proceeds to step 102. For example, the control circuit 20 detects the angle of the slat 14 by detecting the driving state of the motor 16 and the like.

  In step 102, it is determined whether a security mode has been set. In this determination, it is determined whether or not the crime prevention mode has been selected by operating the operation panel 22. If the determination is affirmative, the process proceeds to step 104. If the determination is negative, the process proceeds to step 106.

  In step 104, the motor 16 is driven so as to fully close the slat 14, and the routine proceeds to step 132. That is, as shown in FIG. 3C, since the slat 14 is fully closed, visual inspection of the room from the outside can be disabled.

  In step 106, it is determined whether the daylighting priority mode is set. In this determination, it is determined whether or not the lighting panel priority mode has been selected by operating the operation panel 22. If the determination is affirmative, the process proceeds to step 108. If the determination is negative, the process proceeds to step 114. .

  In step 108, sunlight is detected and the routine proceeds to step 110. That is, the detection result of the solar sensor 24 is acquired by the control circuit 20. Thereby, the control circuit 20 can grasp the illuminance, direction, season, etc. of sunlight from the detection result of the sunlight sensor 24.

  In step 110, the angle of the lighting priority slat 14 is calculated, and the routine proceeds to step 112. That is, the control circuit 20 detects the illuminance from the detection result of the sunlight sensor 24, estimates the current solar radiation angle, and reads the preferentially stored angle corresponding to the detected illuminance and the estimated solar radiation angle. Thus, the angle of the slat 14 is calculated.

  In step 112, the motor 16 is driven so that the angle of the slat 14 becomes the calculated angle, and the routine proceeds to step 132. As a result, as shown in FIG. 3A, the angle of the slat 14 is adjusted so that the lighting is prioritized.

  In step 114, it is determined whether the power generation priority mode is set. The determination determines whether or not the power generation priority mode is selected by operating the operation panel 22, and if the determination is affirmed, the process proceeds to step 116 as the normal mode setting, and if the determination is negative, 124.

  In step 116, detection of the power generation amount of the solar cell 18 is started, and the routine proceeds to step 118. That is, the power meter 26 starts detecting the amount of power generated by the solar cell 18.

  In step 118, the slat angle is changed and the power generation amount is scanned, and the routine proceeds to step 120. That is, the control circuit 20 detects the power generation amount while changing the angle of the slat 14.

  In step 120, the angle of the slat 14 giving priority to the power generation amount is calculated, and the routine proceeds to step 122. That is, the control circuit 20 calculates the angle of the slat 14 by detecting the angle with the largest amount of power generation based on the detected electric power while changing the slat angle.

  In step 122, the motor 16 is driven so that the angle of the slat 14 becomes the calculated angle, and the routine proceeds to step 132.

  In step 124, it is determined whether the normal mode is set. In this determination, it is determined whether or not the operation panel 22 is operated and the normal mode is selected. If the determination is affirmative, the process proceeds to step 126, and if the determination is negative, the process proceeds to step 132 as it is. . When the result is negative, the angle of the slat 14 is manually operated by operating the operation panel 22.

  In step 126, sunlight is detected and the routine proceeds to step 128. That is, the detection result of the solar sensor 24 is acquired by the control circuit 20. Thereby, the control circuit 20 can grasp the illuminance, direction, season, etc. of sunlight from the detection result of the sunlight sensor 24.

  In step 128, the angle of the slat 14 that obtains predetermined lighting and power generation is calculated, and the routine proceeds to step 130. That is, the control circuit 20 detects illuminance from the detection result of the sunlight sensor 24, estimates the current solar radiation angle, and performs predetermined lighting and power generation stored in advance corresponding to the detected illuminance and the estimated solar radiation angle. The angle of the slat 14 is calculated by reading the obtained angle (the angle at which the solar radiation is reflected from the surface of the slat 14 and the reflected light is reflected from the back surface of the upper slat 14 and then enters the room).

  In step 130, the motor 16 is driven so that the angle of the slat 14 becomes the calculated angle, and the routine proceeds to step 132. As a result, as shown in FIG. 3 (B), the solar radiation is reflected by the surface of the slat 14, and the angle of the slat 14 is changed to the angle at which the reflected light is incident on the room after being reflected by the back surface of the upper slat 14. Adjusted.

  In step 132, the control circuit 20 determines whether or not the mode has been changed. In this determination, it is determined whether or not a mode other than the currently set mode is selected by operating the operation panel 22, and if the determination is affirmative, the process returns to step 100 and the above processing is repeated. If the determination is negative, the routine proceeds to step 134.

  In step 134, the control circuit 20 determines whether or not an instruction to end the process has been issued. This determination is made by, for example, determining whether an instruction to turn off the power, an instruction to open the blind portion 12, or the like has been performed. If the determination is negative, the process returns to step 132 and the above processing is repeated. When is affirmed, the series of processing ends.

  As described above, in the power generation blind device 10 according to the present embodiment, when the crime prevention mode is selected, the slat 14 is fully closed regardless of the amount of power generated by the solar cell 18 or indoor lighting. In addition, visual inspection of the room from the outside becomes impossible, and crime prevention can be improved.

  In addition, when the daylighting priority mode is selected, the angle of the slat 14 is adjusted so that solar radiation is reflected on the surface of the slat 14 and enters the room regardless of the power generation amount of the solar cell 18. More light can be taken into the room.

  In addition, when the power generation priority mode is selected, the power amount is scanned while adjusting the angle of the slat 14, and the angle of the slat 14 is adjusted so as to maximize the power amount. It can generate electricity.

  When the normal mode is selected, an angle at which predetermined lighting and power generation are obtained (an angle at which solar radiation is reflected from the surface of the slat 14 and the reflected light is reflected from the back surface of the slat 14 and then enters the room) ), The slat 14 is adjusted so that power can be generated while taking light into the room, and both power generation and daylighting can be achieved.

  That is, the power generation blind device 10 according to the present embodiment can control the angle of the slat 14 according to the purpose of power generation, lighting, crime prevention, etc. by selecting each mode. It can be used conveniently.

  Next, a modified example of the power generation blind device according to the embodiment of the present invention will be described. FIG. 5 is a block diagram showing a configuration of a modified example of the power generation blind device according to the embodiment of the present invention. In addition, about the same structure as the said embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted. Also, the dotted line arrows in FIG. 5 indicate the flow of power, and the solid line arrows indicate the flow of information.

  In the power generation blind device 11 according to the modification, the timepiece calendar counting unit 36 is further connected to the control circuit 21 with respect to the above embodiment.

  The clock calendar counting unit 36 counts the date and time, and is provided for estimating the solar radiation angle that varies depending on the season and time.

  In the above embodiment, when the daylighting priority mode and the normal mode are set, the solar radiation angle is estimated from the detection result of the sunlight sensor 24. However, in this embodiment, the clock calendar counting unit 36 is used. Therefore, the solar radiation angle is estimated from the date and time (season and time) obtained from the clock calendar counting unit 36.

  Then, the process performed in the control circuit 11 of the power generation blind apparatus of a modification is demonstrated in detail. FIG. 6 is a flowchart showing an example of the flow of processing performed by the control circuit 21 in a modification of the power generation blind device according to the embodiment of the present invention. Note that the same processes as those in the above embodiment are described with the same reference numerals.

  First, in step 100, the state of the slat 14 is detected, and the process proceeds to step 101. For example, the control circuit 21 detects the angle of the slat 14 by detecting the driving state of the motor 16 and the like.

  In step 101, the current date and time (season, time, etc.) is acquired, and the process proceeds to step 102. That is, the control circuit 21 acquires the count result of the timepiece calendar counting unit 36.

  In step 102, it is determined whether a security mode has been set. In this determination, it is determined whether or not the crime prevention mode has been selected by operating the operation panel 22. If the determination is affirmative, the process proceeds to step 104. If the determination is negative, the process proceeds to step 106.

  In step 104, the motor 16 is driven so as to fully close the slat 14, and the routine proceeds to step 132. That is, as shown in FIG. 3C, since the slat 14 is in a fully closed state, visual inspection of the room from the outside can be disabled.

  In step 106, it is determined whether the daylighting priority mode is set. In this determination, it is determined whether or not the lighting panel priority mode has been selected by operating the operation panel 22. If the determination is affirmative, the process proceeds to step 108. If the determination is negative, the process proceeds to step 114. .

  In step 108, sunlight is detected and the routine proceeds to step 109. That is, the detection result of the solar sensor 24 is acquired by the control circuit 21. Thereby, the control circuit 21 can grasp the illuminance, direction, season, etc. of sunlight from the detection result of the sunlight sensor 24.

  In Step 109, the angle of the lighting priority slat 14 is calculated from the acquired date and time and the sunlight detection result, and the process proceeds to Step 112. That is, the control circuit 21 detects the illuminance from the sunlight sensor 24, estimates the current solar radiation angle from the date and time acquired from the watch calendar counting unit 36, and stores in advance corresponding to the detected illuminance and the estimated solar radiation angle. The angle of the slat 14 is calculated by reading the angle giving priority to the daylighting.

  In step 112, the motor 16 is driven so that the angle of the slat 14 becomes the calculated angle, and the routine proceeds to step 132. As a result, as shown in FIG. 3A, the angle of the slat 14 is adjusted so that the lighting is prioritized.

  In step 114, it is determined whether the power generation priority mode is set. The determination determines whether or not the power generation priority mode is selected by operating the operation panel 22, and if the determination is affirmed, the process proceeds to step 116 as the normal mode setting, and if the determination is negative, 124.

  In step 116, detection of the power generation amount of the solar cell 18 is started, and the routine proceeds to step 118. That is, the power meter 26 starts detecting the amount of power generated by the solar cell 18.

  In step 118, the slat angle is changed and the power generation amount is scanned, and the routine proceeds to step 120. That is, the control circuit 21 detects the power generation amount while changing the angle of the slat 14.

  In step 120, the angle of the slat 14 giving priority to the power generation amount is calculated, and the routine proceeds to step 122. That is, the control circuit 21 calculates the angle of the slat 14 by detecting the angle with the largest amount of power generation based on the detected power if the slat angle is changed.

  In step 122, the motor 16 is driven so that the angle of the slat 14 becomes the calculated angle, and the routine proceeds to step 132.

  In step 124, it is determined whether the normal mode is set. In this determination, it is determined whether or not the operation panel 22 is operated and the normal mode is selected. If the determination is affirmative, the process proceeds to step 126, and if the determination is negative, the process proceeds to step 132 as it is. . When the result is negative, the angle of the slat 14 is manually operated by operating the operation panel 22.

  In step 126, sunlight is detected and the routine proceeds to step 127. That is, the detection result of the solar sensor 24 is acquired by the control circuit 21. Thereby, the control circuit 21 can grasp the illuminance, direction, season, etc. of sunlight from the detection result of the sunlight sensor 24.

  In step 127, the angle of the slat 14 that obtains predetermined lighting and power generation is calculated from the acquired date and time and the sunlight detection result, and the process proceeds to step 130. That is, the control circuit 21 detects the illuminance from the detection result of the sunlight sensor 24, estimates the current solar radiation angle from the date and time acquired from the watch calendar counting unit 36, and corresponds to the detected illuminance and the estimated solar radiation angle. The slats are read out by reading the angle for obtaining the predetermined lighting and power generation stored in advance (the angle at which the solar radiation is reflected from the surface of the slat 14 and the reflected light is reflected from the back surface of the upper slat 14 and then enters the room). The angle of 14 is calculated.

  In step 130, the motor 16 is driven so that the angle of the slat 14 becomes the calculated angle, and the routine proceeds to step 132. As a result, as shown in FIG. 3 (B), the solar radiation is reflected by the surface of the slat 14, and the angle of the slat 14 is changed to the angle at which the reflected light is incident on the room after being reflected by the back surface of the upper slat 14. Adjusted.

  In step 132, the control circuit 21 determines whether or not the mode has been changed. In this determination, it is determined whether or not a mode other than the currently set mode is selected by operating the operation panel 22, and if the determination is affirmative, the process returns to step 100 and the above processing is repeated. If the determination is negative, the routine proceeds to step 134.

  In step 134, the control circuit 21 determines whether or not an instruction to end the process has been issued. This determination is made by, for example, determining whether an instruction to turn off the power, an instruction to open the blind portion 12, or the like has been performed. If the determination is negative, the process returns to step 132 and the above processing is repeated. When is affirmed, the series of processing ends.

  Even in this manner, the angle of the slat 14 can be controlled according to the purpose of power generation, lighting, crime prevention, etc. by selecting the mode, as in the above embodiment. Can be used conveniently.

  In the above-described embodiment and modification, the mode setting is determined in the order of the crime prevention mode, the daylighting priority mode, the power generation priority mode, and the normal mode. However, the order of determination is not limited to this, and other You may make it judge in order of.

  Further, in the above-described embodiment and modification, the example including the four modes of the crime prevention mode, the daylighting priority mode, the power generation priority mode, and the normal mode has been described, but the present invention is not limited to this. One or more modes may be provided, or other modes other than the above four modes may be provided.

  In the embodiment and the modification described above, when the crime prevention mode is selected, the motor 16 is driven so as to fully close the slats 14 so that the inside of the room cannot be seen from the outside. However, it may not be fully closed. In other words, the angle of the slat 14 may be adjusted to such an extent that visual inspection of the room from the outside is suppressed.

  Further, in the above-described embodiment and modification, the angle for prioritizing the lighting stored in advance corresponding to the illuminance and the solar radiation angle is read and the angle of the slat 14 is adjusted. However, the present invention is not limited to this. For example, an illuminance sensor may be provided on the indoor side, and the angle of the slat 14 may be adjusted so that the illuminance in the room becomes the highest.

  Further, in the above-described embodiment and modification, the solar cells 18 are provided on both surfaces of the slat 14, but the present invention is not limited to this, and the solar cells 18 may be provided only on the front surface side or the back surface side. .

  Moreover, in a modification, you may make it provide the mode which switches a mode automatically for every season. Specifically, in summer, the sun is strong, so the crime prevention mode is executed, in winter the sunlight priority mode is executed to take in sunlight, and in spring and autumn, the angle is between the crime prevention mode and the lighting priority mode. Alternatively, an intermediate mode for adjusting the slats 14 may be executed.

  Furthermore, in the above-described embodiments and modifications, the blind device has been described as an example. However, the present invention is not limited to this, and a blind shutter having a blind function and a shutter function may be applied. That is, the crime prevention effect can be further exhibited by executing the crime prevention mode by applying the blind shutter instead of the power generation blind devices 10 and 11 of the above-described embodiments and modifications.
