  Hereinafter, an embodiment of a blind control device, a blind control system, and a blind control method according to the present invention will be described with reference to the drawings.

  FIG. 1 shows a blind control system 1 of the first embodiment.

  In the blind control system 1 of the present embodiment, the blind 2 is suspended from the ceiling 52 toward the floor 53 adjacent to the inside of the window 51. The height of the blind 2 can be changed manually or automatically according to the situation, that is, the distance from the ceiling at the lower end of the blind 2 can be changed. Further, when not in use, all the blinds 2 can be raised to the ceiling 52 side. The blind 2 has a plurality of slats 3. Each of the plurality of slats 3 is formed such that the angle can be changed. In the present embodiment, the angle of the blind 2 is the angle of the uppermost slat 3. Moreover, although the blind control system 1 of this embodiment is applied to the blind 2 attached indoors, it is applicable also to the external blind or the double skin internal blind installed between two glass.

  The blind control device 30 is a device that controls the blind 2. Note that the blind control device 30 of the present embodiment can be applied to a general blind 2.

  The blind control device 30 of the first embodiment includes the outdoor light state acquired from the outdoor light detection unit 11 that detects the state of outdoor light such as the amount of solar radiation or outdoor illuminance, the period acquired from the period determination unit 12, and the outside air. From the outside air temperature acquired from the thermometer 13, the room temperature acquired from the indoor thermometer 14, the air conditioning state acquired from the air conditioner 15, and the blind angle acquired from the blind angle detector 16, using a matrix table, Select the control mode and determine the blind control angle.

  FIG. 2 shows an example of a matrix table used for the blind control device 30 of the blind control system 1 of the first embodiment.

The vertical axis of the matrix table is divided into day and night, and further divided according to the presence or absence of daytime solar radiation. The solar radiation amount is acquired from the outdoor light state acquisition unit 11 shown in FIG. 1 such as a solar radiation sensor. As a solar radiation amount sensor, there are a method using a solar tracking type solar radiation meter or a method using a plurality of solar radiation meters. The solar tracking solar radiation meter directly measures direct light and acquires diffuse solar radiation amount and direct solar radiation amount. When a plurality of solar radiation systems are used, the direct solar radiation amount may be obtained from a vertical plane solar radiation amount measurement value by a calculation formula, and the diffuse solar radiation amount may be obtained from a difference between the horizontal solar radiation amount and the direct solar radiation amount. The date and time, particularly day and night, may be obtained from a clock or the like built in the apparatus. The acquired amount of solar radiation is determined to have solar radiation when it is large, and when it is small, it is determined that there is no solar radiation as compared to a predetermined solar radiation amount threshold.

  Thus, the blind control device 30 of the present embodiment can be accurately controlled according to the state of solar radiation.

  The horizontal axis of the matrix table is divided according to the air conditioning state. In order to divide according to the air-conditioning state, first, it is divided into summer, intermediate, or winter. When the measured room temperature Ti is lower than the measured outside temperature To, it is summer, when the measured outside temperature To is less than or equal to a predetermined outside temperature threshold To ′, it is winter, and the measured outside temperature To is a predetermined outside temperature threshold To. If it is higher and lower than the measured room temperature Ti, it is divided into an intermediate period.

  Thus, the blind control device 30 of the present embodiment can be accurately controlled almost every season.

  The summer period, the intermediate period, and the winter period are divided as follows according to the air conditioning state. The air conditioning state is acquired from the air conditioner 15 shown in FIG. 1 and is classified into cooling, heating, or air conditioning stop. Further, the cooling is divided into a case where the room temperature Ti is higher than a predetermined room temperature threshold Ti ′ and a case where the room temperature Ti is equal to or lower than the predetermined room temperature threshold Ti ′.

  Thus, the blind control device 30 of the present embodiment can be accurately controlled according to the usage state of the air conditioner 15.

  The blind control device 30 determines the mode of the blind 2 by applying the detected ambient environmental condition to the matrix table shown in FIG. After the mode is determined, the plurality of slats 3 are driven according to the blind angle acquired from the blind angle detection unit 16 and the determined control angle, and the angle of the plurality of slats 3 is changed by the driving unit 61.

  Next, each mode selected in the matrix table will be described.

  The control according to the matrix table of the blind control device 30 has a fully closed mode, a view mode, and a lighting angle mode. It should be noted that the hatched portion is a case where it is considered that control is not necessary, such as when heating in summer.

  The fully closed mode is a mode in which the blind 2 is fully closed. The fully-closed mode is selected when the load due to solar radiation is large and when the solar radiation is shielded or insulated. For example, in the summer, when there is solar radiation in the daytime and the room is cooled, the blind 2 is fully closed to shield the solar radiation. In both summer and winter, the blind 2 is fully closed at night for heat insulation.

  The view mode is a mode in which the blind 2 is fully opened. The view mode is selected when daylight is used or when indoor heat is radiated to the outside air. For example, when there is no daytime solar radiation and the cold / hot water of the air conditioner is stopped, the blind 2 is fully opened to use daylight. Further, when the cooling is activated and the cold / hot water of the air conditioner is stopped at night in the intermediate period, the blind 2 is fully opened to dissipate heat.

  The lighting angle mode is a mode for controlling the angle of the slat 3 of the blind 2. The lighting angle mode is selected when sunlight is introduced into the room by controlling the angle of the slat 3. For example, when there is sunlight in the daytime and the cold / hot water of the air conditioner is stopped, the angle of the slat 3 of the blind 2 is controlled to introduce sunlight.

  The toned part of the matrix table shown in FIG. 2 is a part for CO2 saving control. Here, a mode with a small amount of CO2 emission is selected from the two modes described in the matrix table. For example, in summer, when there is no daytime solar radiation, when the air conditioner is in cooling operation, a mode in which the amount of CO2 emission is small is selected from either the view or the full closure. The technique described in Patent Document 2 may be used to calculate the CO2 emission amount.

  As described above, since the blind control device 30 of the first embodiment controls the blind 2 using the matrix table, the calculation load is reduced as compared with the case where the surrounding state is measured and sequentially calculated and controlled. And time can be shortened, and quick control is possible.

  In addition, in the conventional CO2 saving control, control was performed according to the surrounding conditions in real time, so even in clear weather, the amount of solar radiation is large when there are many clouds, and chattering occurs at the time of full closure and daylight use judgment However, since the blind control device 30 of the first embodiment controls the blind 2 instead of the mode in which CO2 control is conventionally performed in the fully closed or fully opened mode, the occurrence of chattering or the like occurs. Can be suppressed. For example, in the summer season, when the solar air is being cooled, the blind 2 may be controlled to be fully closed without calculation, in order to shield the solar radiation. Such control enables more rapid control.

  FIG. 3 shows an example of a matrix table used for the blind control device 30 of the blind control system 1 of the second embodiment.

  The matrix table shown in FIG. 3 is an example in which the CO2 saving control is further reduced. For example, when there is no solar radiation at noon in summer and cooling is stopped, CO2 saving control is performed in the matrix table shown in FIG. 2, but in the matrix table shown in FIG. I do. Further, when there is no solar radiation at midday and cooling is stopped, CO2 saving control is performed in the matrix table shown in FIG. 2, but blind 2 is controlled in the matrix table shown in FIG. I do.

  Thus, since the CO2 saving control is further reduced, the occurrence of chattering and the like can be further suppressed.

  FIG. 4 shows an example of a matrix table used for the blind control device 30 of the blind control system 1 of the third embodiment.

  The blind control device 30 of the blind control system 1 according to the third embodiment shown in FIG. 4 determines the control angle of the blind 3 by selecting a control mode using a matrix table with dazzling as an index.

  The vertical axis of the matrix table is divided into day and night, and the day is further divided according to the degree of glare. A glare evaluation value may be used as an index of glare. The glare evaluation value may be obtained by referring to Non-Patent Document 1 from the amount of solar radiation acquired from the solar radiation amount sensor 11 or the like. And when the calculated | required glare evaluation value is more than a predetermined threshold value, it is judged as dazzling A. Further, when the obtained glare evaluation value is smaller than a predetermined threshold value, it is determined that B is not dazzling.

  The horizontal axis of the matrix table is divided according to the air conditioning state. In order to divide according to the air-conditioning state, first, it is divided into summer, intermediate, or winter. And in the matrix table | surface of 3rd Embodiment, it divides into during operation | movement and a stop for every period.

  The blind control device 30 determines the mode of the blind 2 by applying the detected ambient environmental condition to the matrix table shown in FIG. After the mode is determined, the plurality of slats 3 are driven according to the blind angle acquired from the blind angle detection unit 16 and the determined control angle, and the angle of the plurality of slats 3 is changed by the driving unit 61.

  For example, if the air conditioner is in cooling operation during midday, and it is determined that it is dazzling A, the matrix table shown in FIG. 3 performs CO2 saving control, but the matrix table shown in FIG. Then, the blind 2 is controlled to be fully closed.

  As described above, since the blind control device 30 of the third embodiment controls the blind 2 using the matrix table, the time can be shortened compared with the case where the control is performed while measuring the surrounding state. It becomes possible to control to. Moreover, it becomes possible to reduce glare by using the index of glare.

  FIG. 5 shows a blind control system 1 of the fourth embodiment.

  The blind control device 30 of the fourth embodiment includes an outdoor light detection unit 11, a period determination unit 12, an outside air thermometer 13, an indoor thermometer 14, an air conditioner 15, and the like used in the blind control system 1 of the first embodiment. In addition to the blind angle detector 16, the control mode is selected from the position information of the office worker detected by the human sensor 17 using the matrix table to determine the blind control angle.

  FIG. 6 shows an example of a matrix table used for the blind control device 30 of the blind control system 1 of the fourth embodiment.

  The blind control device 30 according to the fourth embodiment shown in FIG. 6 selects a control mode and determines a blind control angle using a matrix table corresponding to the position information of the worker in the room.

  The vertical axis of the matrix table is divided into day and night, and the day is further divided according to the position information in the office of the worker. The position information of the office worker is divided into “a” when there is an office worker by the window, “b” when there is an office worker other than the window, and “c” when there is no office worker.

  The horizontal axis of the matrix table is divided according to the air conditioning state. In order to divide according to the air-conditioning state, first, it is divided into summer, intermediate, or winter. And in the matrix table | surface of 4th Embodiment, it divides into during operation | movement and a stop for every period.

  The blind control device 30 determines the mode of the blind 2 by applying the detected ambient environmental conditions to the matrix table shown in FIG. After the mode is determined, the plurality of slats 3 are driven according to the blind angle acquired from the blind angle detection unit 16 and the determined control angle, and the angle of the plurality of slats 3 is changed by the driving unit 61.

  For example, the daytime control in each period will be described. When there is an office worker by the window a, control is mainly performed to reduce glare. When the office worker is absent c, control is performed without considering the glare. When there is an office worker other than the window b, control is performed to reduce glare when there is solar radiation, and control is performed without considering glare when there is no solar radiation. In the control to alleviate the glare, it is preferable that the blind 2 is fully closed to block solar radiation.

As described above, according to the blind control device 30 of the fourth embodiment, in the matrix table, the presence of solar radiation and the absence of solar radiation are respectively divided by the position information of the indoor office workers, so that the positions of the indoor office workers exist. Accordingly, it becomes possible to control accurately.

  In the embodiment according to the present invention, since the indoor state differs depending on the location of the building where the blind 2 is installed and the position of the window, the matrix table may be set by the user.
