[First Embodiment]
FIG. 1 is a schematic plan view of an office floor on which an electric blind control system to which the electric blind control device according to the first embodiment of the present invention is applied is installed. As shown in the figure, windows W1 to W4 for taking in external light are provided on the office floor. In the office floor, the electric blinds 1A to 1D (hereinafter, the electric blinds 1A to 1D are collectively referred to as the electric blinds 1 or corresponding to the windows W1 to W4, respectively, may be referred to as the electric blinds 1). .) Are installed. Each of the electric blinds 1A to 1D takes in a blind control command supplied from an electric blind control device (not shown), which will be described later, and operates the blind based on the blind control command to block outside light or make incidents. It is an electric blind that adjusts the amount.

  On the opposite side of the window W1 (inside the office floor) across the electric blind 1A, desks A1 to A4 are arranged in order from the electric blind 1A. Further, on the opposite side of the window W2 across the electric blind 1B, the desk B1 to the desk B4 are arranged in order from the electric blind 1B. Further, on the opposite side of the window W3 across the electric blind 1C, the desk C1 to the desk C4 are arranged in order from the electric blind 1C. Furthermore, on the opposite side of the window W4 across the electric blind 1D, a desk D1 to a desk D4 are arranged in order from the electric blind 1D. Hereinafter, the desks A1 to A4, the desks B1 to B4, the desks C1 to C4, and the desks D1 to D4 may be collectively referred to or simply referred to as “desks”.

  In addition, this embodiment is applicable also when a chair, a sofa, a bed, etc. are arrange | positioned besides a desk. The positions where these desks and the like are present positions where persons can stay at the position where the desks or the like are provided for an arbitrary time.

  Next, the functional configuration of the electric blind control system in the first embodiment will be described. FIG. 2 is a block diagram showing a functional configuration of the electric blind control system. As shown in the figure, the electric blind control system 100 includes an occupancy detection device 10, an electric blind control device 20, and electric blinds 1A to 1D.

The presence detection device 10 detects the presence of a person at the desks A1 to A4, the desks B1 to B4, the desks C1 to C4, and the desks D1 to D4 arranged on the office floor. Seat detection information is generated and supplied to the electric blind control device 20. The seated state is either a seated state where a person is seated at a desk or a seated state where a person is away. The presence detection device 10 detects the presence state and generates presence detection information every time a person sits on the desk or leaves the desk, and the presence detection information is sent to the electric blind control device 20. Supply.
Specifically, the presence detection device 10 applies, for example, RFID (Radio Frequency IDentification) technology, detects a seated state when a person is seated at a desk, and identifies the person's identification information (person ID) and the person. The identification information (desk ID) of the desk where the person is seated is transmitted to the electric blind control device 20 as presence detection information. In addition, when the person leaves, the presence detection device 10 detects the absence state, and transmits the desk ID of the desk from which the person has left to the electric blind control device 20 as presence detection information.

  More specifically, each person using the desk wears or possesses an IC tag enclosing an IC chip, a battery, and an antenna in which his / her personal ID (for example, an employee number) is stored. This IC tag is an active tag, and has a function of reading a person ID stored in the IC chip by battery driving and transmitting it from the antenna. Each desk is provided with a reader device that receives and captures the person ID transmitted from the antenna of the IC tag. The reader device and the IC tag are arranged so that radio waves can be transmitted and received only between the antenna of the reader device installed at the desk and the antenna of the IC tag worn or possessed by a person seated at the desk. Radio transmission power is limited. When the reader device receives and captures the person ID transmitted from the IC tag, the reader device transmits the person ID and the desk ID stored in advance in the reader device to the electric blind control device 20 as presence detection information. . When the reader device cannot receive the person ID transmitted from the IC tag, the reader device transmits the desk ID of the reader device to the electric blind control device 20 as presence detection information.

  In addition, you may comprise an IC tag with a passive tag. In this case, when the person holding the IC tag is seated at the desk, the IC tag is placed on or attached to the IC tag reading unit of the reader device so that the IC tag and the reader device can communicate with each other and leave the seat. When you are away with your IC tag. That is, when leaving the seat, the IC tag is separated from the IC tag reading unit of the reader device to disable communication.

  The electric blind control device 20 controls the operation of the electric blind 1A according to the presence state of the desks A1 to A4, and controls the operation of the electric blind 1B according to the presence state of the desks B1 to B4. The operation of the electric blind 1C is controlled according to the presence state of C4, and the operation of the electric blind 1D is controlled according to the presence state of the desks D1 to D4.

  Specifically, the electric blind control device 20 corresponds to each of the electric blinds 1 </ b> A to 1 </ b> D and includes blind control priority including the priority of blind control for each of the four target desks and the control amount of the electric blind 1. Store quantity information. In addition, the electric blind control device 20 should be controlled in correspondence with each of the electric blinds 1A to 1D when the desk IDs of the four desks to be used and no one is seated at these four desks. The absence control amount information including the absence control amount that is the control amount of the electric blind 1 is stored.

  And if the electric blind control apparatus 20 takes in the presence detection information supplied from the presence detection apparatus 10, it will update the information showing the presence state of the whole office floor with the presence detection information. Then, the electric blind control device 20 determines whether or not the electric blind 1 can be controlled based on the updated information indicating the presence state, the absence control amount information, and the blind control amount information. When it is determined that control is possible, the electric blind control device 20 generates a blind control command and supplies the blind control command to the electric blind 1 to be controlled.

The functional configuration of the electric blind control device 20 will be described in more detail. The electric blind control device 20 includes a blind control amount information storage unit 21, an absence control amount information storage unit 22, a presence state registration unit 23, a blind control command generation unit 24, and a blind control unit 25.
The blind control amount information storage unit 21 stores the blind control amount information. The absentee control amount information storage unit 22 stores the absentee control amount information. The blind control amount information storage unit 21 and the absence control amount information storage unit 22 are configured by, for example, a magnetic hard disk device or a memory. Specific examples of the blind control amount information and the absence control amount information will be described later.

The presence state registration unit 23 is configured by a memory, for example, and captures and stores presence detection information supplied from the presence detection device 10.
Specifically, when the office floor shown in FIG. 1 is taken as an example, the presence status registration unit 23 uses each of the 16 desk IDs and the person ID corresponding to each desk ID as pair data, and the 16 pairs A memory map for mapping data is created in the memory space. That is, the 16 pairs of data developed in this memory map are information representing the presence state. In this memory map, a data group of a set of desk IDs of desks A1 to A4 and a person ID corresponding to each desk ID is group 1, and each desk ID of desks B1 to B4 and a person corresponding to each desk ID. The data group of the set with the ID is group 2, and the data group of the set of the desk IDs of the desks C1 to C4 and the person ID corresponding to each desk ID is the group 3, and the desk IDs of the desks D1 to D4. The data group of the set of the person ID corresponding to each desk ID is group 4. When the presence detection information supplied from the presence detection device 10 is taken in, the presence status registration unit 23, when the presence detection information includes a desk ID and a person ID, Pair data is newly registered or updated in the memory map using the desk ID as a key. Further, when the presence detection information is a desk ID, the presence status registration unit 23 stores the person ID as null data, and the pair data of the desk ID and null data as presence detection information as a key with the desk ID as a key. Register or update a new map.

The blind control command generation unit 24 includes a pair of a desk ID of a desk in which a person is seated and a person ID of a person seated at the desk in the data group to which the desk ID included in the presence detection information belongs. Read data from memory map. Specifically, when the presence detection information supplied from the presence detection device 10 is stored in the presence state registration unit 23, the blind control command generation unit 24 determines the desk ID included in the presence detection information. The pair data of the desk ID and the non-null person ID in the data group to which it belongs (any one of groups 1 to 4) is read from the memory map.
Then, when the pair data is read from the memory map, the blind control command generation unit 24 turns on the presence flag data (for example, “1”).

  When all the pair data in the data group to which the desk ID included in the presence detection information belongs is the pair data of the desk ID and null data, that is, no one is seated at the desk of the target group. In this case, the blind control command generation unit 24 cannot read the pair data of the desk ID and the person ID that is not null data from the memory map. In this case, the blind control command generation unit 24 turns off the presence flag data (for example, “0”).

  When the presence flag data is ON, the blind control command generation unit 24 uses the desk ID read from the memory map as a search key, and the priority and control associated with the search key from the blind control amount information storage unit 21. Read quantity and blind ID. The blind ID is identification information associated with the electric blind 1 in advance. Then, the blind control command generation unit 24 uses the desk ID as a key, generates a control table of priority and control amount associated with the key, and associates the control table with the blind ID. Then, the blind control command generation unit 24 extracts a record having the highest priority from the control table, and further extracts a control amount from the record. Then, the blind control command generation unit 24 determines whether or not the extracted control amount is the same as the control amount currently supplied to the electric blind 1 corresponding to the blind ID. Then, when it is determined that the extracted control amount is different from the control amount currently supplied to the electric blind 1, the blind control command generation unit 24 generates a blind control command including the extracted control amount.

  When the presence flag data is OFF, the blind control command generation unit 24 uses the desk ID, which is presence detection information, as a search key and is associated with the search key from the absence control amount information storage unit 22. Reads out-of-office control amount and blind ID. Then, the blind control command generation unit 24 generates a blind control command including the read absence amount.

  The blind control command generation unit 24 supplies the generated blind control command and blind ID to the blind control unit 25. Then, the blind control command generation unit 24 stores the control amount included in the blind control command in association with the blind ID.

  The blind control unit 25 takes in the blind control command and the blind ID supplied from the blind control command generation unit 24, and transmits the blind control command to the electric blind 1 corresponding to the blind ID.

  Each of the electric blinds 1 </ b> A to 1 </ b> D includes a lifting motor that moves up and down slats configured in multiple layers, a rotating motor that changes the angle by rotating the slats, and a motor control unit that controls the lifting motor and the rotating motor. It is an electric blind equipped with. The motor control unit takes in the blind control command supplied from the blind control unit 25 of the electric blind control device 20, and drives the lifting motor to move the slat up and down based on the control amount included in the blind control command. The angle of the slat is changed by driving the motor for rotation.

  Each of FIGS. 3A to 3C is a diagram illustrating a data configuration of blind control amount information. FIG. 5A shows an example of blind control amount information corresponding to the electric blind 1A (blind ID = “ID01A”), and FIG. 5B corresponds to the electric blind 1B (blind ID = “ID01B”). (C) is an example of blind control amount information corresponding to the electric blind 1C (blind ID = “ID01C”). An example of blind control amount information corresponding to the electric blind 1D is omitted.

As shown in FIGS. 3A to 3C, the blind control amount information is a data table in which “desk ID”, “priority”, and “control amount” are associated with each electric blind 1. . The blind control amount information is stored in the blind control amount information storage unit 21 in association with the “blind ID”. “Desk ID” is identification information of a desk associated with the electric blind 1 corresponding to the blind ID. “Priority” is information indicating the order in which the electric blind control device 20 determines the control amount of the electric blind 1. In the examples of FIGS. 9A to 9C, the priority is “1” which is the highest, and becomes lower as the number increases. This priority is set such that the closer the desk is to the electric blind 1, the higher the priority. That is, the electric blind control device 20 controls the electric blind 1 according to the desk closest to the electric blind 1. In FIG. 3C, priority = “−” means that no priority is designated. “Control amount” is data representing a control amount for the electric blind 1 to be shielded from light or dimmed, and the set angle of the slat of the electric blind 1 or the increase of the slat suitable for suppressing glare at the corresponding desk. This is data representing a rate or a descending rate. Specifically, the control amount = “65 degrees” in FIG. 6A is, for example, an angle when the slat is leveled is 0 degrees, and the convex surface of the slat is rotated by 65 degrees in a direction to directly receive external light. Means that. Further, the control amount = “40%” in FIG. 5B means that, for example, the slat is raised by 40% from the state where the blind is lowered.
Note that the blind control amount information may be provided according to a period such as season, month, day, or time.

FIG. 4 is a diagram illustrating a data configuration of control amount information when absent. As shown in the figure, the absence control amount information is a data table in which “blind ID”, “desk ID”, and “absence control amount” are associated with each other. “Blind ID” is identification information associated with each of the electric blinds 1A to 1D. “Desk ID” is the desk ID of the desk associated with the electric blind 1 associated with the blind ID. The “control amount when absent” is a control amount for controlling the electric blind 1 when no one is sitting at the four desks. Specifically, the control amount in absence in the figure = “100%” means that, for example, all the blinds are raised. Further, the control amount when absent = “− 60 degrees” means, for example, that the angle when the slat is leveled is 0 degree, and the slat is rotated 60 degrees in the direction in which the convex surface of the slat faces the office floor. That is, the “absent control amount” is, for example, a control amount that can appropriately exert the energy saving effect.
The absence control amount information may be provided according to a period such as season, month, day, or time.

  FIG. 5 is a diagram illustrating a data configuration of a control table generated by the blind control command generation unit 24 when the presence flag data is ON. This figure is a control table corresponding to the electric blind 1A (blind ID = “ID01A”). As shown in the figure, the control table is a data table in which “desk ID”, “priority”, and “control amount” are associated with each other. “Desk ID” is a desk ID read from the memory map of the attendance state registration unit 23 by the blind control command generation unit 24. That is, it means that the desk with the desk ID = “ID_A2” and the desk with the desk ID = “ID_A3” are in a seated state. The “priority”, “control amount”, and “blind ID” are the priority, control amount, and blind ID that the blind control command generation unit 24 reads from the blind control amount information storage unit 21 using the desk ID as a search key. is there. In the example of the control table shown in the figure, the electric blind control device 20 extracts a record having the desk ID “ID_A2” as the highest priority record from the control table, and further, the control amount = “55” from the record. “Degree” is extracted.

Next, the operation of the electric blind control device 20 will be described. FIG. 6 is a flowchart showing a procedure of processing in which the electric blind control device 20 controls the electric blind 1.
First, in step S1, the presence state registration unit 23 is in an input reception state until presence detection information is supplied from the presence detection device 10 (S1: NO). When presence detection information is supplied from the presence detection device 10 (S1: YES), in step S2, the presence state registration unit 23 takes in and stores the supplied presence detection information, that is, presence. Register your seat status.
Specifically, when the presence status registration unit 23 takes in the supplied presence detection information, if the presence detection information is a desk ID and a person ID, a pair of the desk ID and the person ID is set. Data is newly registered or updated in the memory map using the desk ID as a key. Further, when the presence detection information is a desk ID, the presence status registration unit 23 stores the person ID as null data, and the pair data of the desk ID and null data as presence detection information as a key with the desk ID as a key. Register or update a new map.

Next, in step S3, the blind control command generation unit 24 checks the presence status of the four desks corresponding to the data group to which the desk ID included in the presence detection information belongs.
Specifically, the blind control command generation unit 24 stores pair data of a desk ID and a non-null person ID in a data group (any of groups 1 to 4) to which the desk ID included in the presence detection information belongs. Read from. Then, when the pair data is read from the memory map, the blind control command generation unit 24 turns on the presence flag data (for example, “1”). In addition, when the pair data of the desk ID and the person ID that is not null data cannot be read from the memory map, the blind control command generation unit 24 turns the presence flag data off (for example, “0”).

  In step S4, if the blind control command generation unit 24 determines that a person is seated at at least one of the four desks, in other words, if the presence flag data is turned on (S4: NO), step The process proceeds to S5. If the blind control command generation unit 24 determines that the person is away from all four desks, in other words, if the presence flag data is turned off (S4: YES), the process proceeds to step S8.

In step S <b> 5, the blind control command generation unit 24 generates a control table based on the data in the memory map of the presence state registration unit 23 and the blind control amount information stored in the blind control amount information storage unit 21.
Specifically, the blind control command generation unit 24 uses the desk ID read from the memory map as a search key, the priority, control amount, and blind ID associated with the search key from the blind control amount information storage unit 21. Is read. Next, the blind control command generation unit 24 uses the desk ID as a key, generates a control table of priority and control amount associated with the key, and associates the control table with the blind ID.

Next, in step S6, the blind control command generator 24 determines whether or not the corresponding electric blind 1 can be controlled based on the control table.
Specifically, the blind control command generation unit 24 extracts a record having the highest priority from the control table, and then extracts a control amount from the record. Next, the blind control command generation unit 24 determines whether or not the extracted control amount is the same as the control amount currently supplied to the electric blind 1 corresponding to the blind ID.
If the blind control command generation unit 24 determines that the extracted control amount is different from the control amount currently supplied to the electric blind 1 (S6: YES), the process proceeds to step S7. On the other hand, when it is determined that the extracted control amount is the same as the control amount currently supplied to the electric blind 1 (S6: NO), the blind control command generation unit 24 returns to the process of step S1.

  In step S7, the blind control command generator 24 generates a blind control command including the control amount extracted from the control table.

  On the other hand, in step S8 following step S4: YES, the blind control command generation unit 24 uses the desk ID, which is presence detection information, as a search key and is associated with the search key from the absence control amount information storage unit 22. Reads out-of-office control amount and blind ID. Next, the blind control command generation unit 24 generates a blind control command including the read absence amount control amount.

  In step S <b> 9, the blind control command generation unit 24 supplies the generated blind control command and blind ID to the blind control unit 25. Next, the blind control command generation unit 24 stores the control amount included in the blind control command in association with the blind ID. Next, the blind control unit 25 takes in the blind control command and the blind ID supplied from the blind control command generation unit 24, and transmits the blind control command to the electric blind 1 corresponding to the blind ID. Next, the process returns to step S1.

  As described above, according to the electric blind control system 100 to which the electric blind control device 20 according to the first embodiment of the present invention is applied, according to the change in the desk presence state detected by the presence detection device 10, The electric blind control device 20 adjusts the angle of the slats of the electric blinds 1A to 1D or the elevation of the slats. At this time, the electric blind control device 20 controls the electric blind 1 according to the person seated at the position closest to the electric blind 1. By configuring the electric blind control device 20 in this manner, the person sitting at the position closest to the electric blind 1 is not affected by glare, and the electric blind 1 is controlled in accordance with the presence of the desk. It can be performed. Further, when the electric blind control device 20 detects that no one is seated at the desk associated with the electric blind 1, a person who is affected by glare does not exist and is set in advance. The electric blind 1 is controlled with an energy-saving control amount. By configuring the electric blind control device 20 in this manner, it is possible to appropriately reduce glare and ensure energy saving in the room.

The pair data of the desk ID and the non-null person ID in the data group to which it belongs (any one of groups 1 to 4) is read from the memory map.
Then, when the pair data is read from the memory map, the blind control command generation unit 24a turns on presence flag data (for example, “1”).

  When all the pair data in the data group to which the desk ID included in the presence detection information belongs is the pair data of the desk ID and null data, that is, no one is seated at the desk of the target group. In this case, the blind control command generation unit 24a cannot read the pair data of the desk ID and the person ID that is not null data from the memory map. In this case, the blind control command generation unit 24a turns off the presence flag data (for example, “0”).

  When the presence flag data is ON, the blind control command generation unit 24a uses the desk ID read from the memory map as a search key, and the priority and control associated with the search key from the blind control amount information storage unit 21. Read quantity and blind ID. Further, the blind control command generation unit 24a uses the pair data of the desk ID and the person ID read from the memory map as a search key, and controls the preference value of the control amount associated with the search key from the preference control amount information storage unit 26. Is read. Then, the blind control command generation unit 24a uses the desk ID as a key, generates a control table of priority, control amount, person ID, and control amount preference value associated with the key, and associates the control table with the blind ID. Then, the blind control command generation unit 24a extracts a record having the highest priority from the control table. Then, the blind control command generation unit 24a extracts the preference value as the control amount when the control value preference value is stored in the extracted record, and when the control amount preference value is not stored in the record. Extract control amount. Then, the blind control command generation unit 24a determines whether or not the extracted control amount and the control amount currently supplied to the electric blind 1 corresponding to the blind ID are the same. Then, when it is determined that the extracted control amount is different from the control amount currently supplied to the electric blind 1, the blind control command generation unit 24a generates a blind control command including the extracted control amount.

  When the presence flag data is OFF, the blind control command generation unit 24a uses the desk ID, which is presence detection information, as a search key and is associated with the search key from the absence control amount information storage unit 22. Reads out-of-office control amount and blind ID. Then, the blind control command generation unit 24a generates a blind control command including the read absent time control amount.

  The blind control command generation unit 24 a supplies the generated blind control command and blind ID to the blind control unit 25. Then, the blind control command generation unit 24a stores the control amount included in the blind control command in association with the blind ID.

  FIG. 8 is a diagram illustrating a data configuration of preference control amount information. This figure is an example of preference control amount information corresponding to a person whose person ID = “ID003”. As shown in the figure, the preference control amount information is another data table in which “desk ID” and “preference value” are associated with each person. The preference control amount information is stored in the preference control amount information storage unit 26 in association with the “person ID”. “Desk ID” is identification information of a desk used by a person corresponding to the person ID. That is, in the example of the preference control amount information in the figure, the person with the person ID = “ID003” uses the desk with the desk ID = “ID_A2” and the desk with the desk ID = “ID_B4”. means. The “favorite value” is a favorite value of the control amount of the electric blind 1 appropriate for suppressing glare for the person associated with the person ID, and is set in correspondence with the time zone as shown in FIG. . The preference value of the control amount is data representing the set angle of the slat of the electric blind 1 or the rate of increase or decrease of the slat.

  FIG. 9 is a diagram illustrating a data configuration of a control table generated by the blind control command generation unit 24a when the presence flag data is ON. This figure is a control table corresponding to the electric blind 1A (blind ID = “ID01A”). As shown in the figure, the control table is a data table in which “desk ID”, “priority”, “control amount”, “person ID”, and “favorite value” are associated with each other. “Desk ID” and “Person ID” are the desk ID and person ID read from the memory map of the attendance state registration unit 23 by the blind control command generation unit 24a. The “priority”, “control amount”, and “blind ID” are the priority, control amount, and blind ID that the blind control command generation unit 24a reads from the blind control amount information storage unit 21 using the desk ID as a search key. is there. “Preference value” is a control value preference value read from the preference control amount information storage unit 26 using the desk ID and person ID as search keys by the blind control command generation unit 24a. In the example of the control table shown in the figure, the electric blind control device 20a extracts a record having a desk ID “ID_A2” as the highest priority record from the control table, and further selects a preference value as a control amount from the record. = "60 degrees" is extracted.

Next, the operation of the electric blind control device 20a will be described. The flowchart showing the procedure of the process in which the electric blind control device 20a controls the electric blind 1 is the same as the flowchart shown in FIG. Therefore, description will be made with reference to the flowchart of FIG.
First, in step S1, the presence state registration unit 23 is in an input reception state until presence detection information is supplied from the presence detection device 10 (S1: NO). When presence detection information is supplied from the presence detection device 10 (S1: YES), in step S2, the presence state registration unit 23 takes in and stores the supplied presence detection information, that is, presence. Register your seat status.
Specifically, when the presence status registration unit 23 takes in the supplied presence detection information, if the presence detection information is a desk ID and a person ID, a pair of the desk ID and the person ID is set. Data is newly registered or updated in the memory map using the desk ID as a key. Further, when the presence detection information is a desk ID, the presence status registration unit 23 stores the person ID as null data, and the pair data of the desk ID and null data as presence detection information as a key with the desk ID as a key. Register or update a new map.

Next, in step S3, the blind control command generation unit 24a checks the presence status of the four desks corresponding to the data group to which the desk ID included in the presence detection information belongs.
Specifically, the blind control command generation unit 24a uses a memory map to store pair data of a desk ID and a person ID that is not null data in a data group (any one of groups 1 to 4) to which the desk ID included in the presence detection information belongs. Read from. Then, when the pair data is read from the memory map, the blind control command generation unit 24a turns on presence flag data (for example, “1”). If the pair data of the desk ID and the non-null person ID cannot be read from the memory map, the blind control command generation unit 24a turns the presence flag data off (for example, “0”).

  In step S4, if the blind control command generation unit 24a determines that a person is seated at at least one of the four desks, in other words, if the presence flag data is turned on (S4: NO), step The process proceeds to S5. If the blind control command generation unit 24a determines that the person is away from all four desks, in other words, if the presence flag data is turned off (S4: YES), the process proceeds to step S8.

In step S5, the blind control command generation unit 24a is stored in the memory map data of the presence state registration unit 23, the blind control amount information stored in the blind control amount information storage unit 21, and the preference control amount information storage unit 26. A control table is generated based on the preference control amount information.
Specifically, the blind control command generation unit 24a uses the desk ID read from the memory map as a search key, the priority, the control amount, the blind ID associated with the search key from the blind control amount information storage unit 21, and Is read. Further, the blind control command generation unit 24a uses the pair data of the desk ID and the person ID read from the memory map as a search key, and controls the preference value of the control amount associated with the search key from the preference control amount information storage unit 26. Is read. Next, using the desk ID as a key, the blind control command generation unit 24a generates a control table of priority, control amount, person ID, and control amount preference value associated with the key, and associates the control table with the blind ID. .

Next, in step S6, the blind control command generator 24a determines whether or not the corresponding electric blind 1 can be controlled based on the control table.
Specifically, the blind control command generation unit 24a extracts a record having the highest priority from the control table. Next, when the control value preference value is stored in the extracted record, the blind control command generation unit 24a extracts the preference value as the control amount, and the control value preference value is not stored in the record. Extracts the controlled variable. Next, the blind control command generation unit 24a determines whether or not the extracted control amount is the same as the control amount currently supplied to the electric blind 1 corresponding to the blind ID.
If the blind control command generation unit 24a determines that the extracted control amount is different from the control amount currently supplied to the electric blind 1 (S6: YES), the process proceeds to step S7. On the other hand, when the blind control command generation unit 24a determines that the extracted control amount is the same as the control amount currently supplied to the electric blind 1 (S6: NO), the process returns to the process of step S1.

  In step S7, the blind control command generation unit 24a generates a blind control command including the control amount extracted from the control table.

  On the other hand, in step S8 following step S4: YES, the blind control command generation unit 24a uses the desk ID, which is presence detection information, as a search key and is associated with the search key from the absent control amount information storage unit 22. Reads out-of-office control amount and blind ID. Next, the blind control command generation unit 24a generates a blind control command including the read absent time control amount.

  In step S <b> 9, the blind control command generation unit 24 a supplies the generated blind control command and blind ID to the blind control unit 25. Next, the blind control command generation unit 24a stores the control amount included in the blind control command in association with the blind ID. Next, the blind control unit 25 takes in the blind control command and the blind ID supplied from the blind control command generation unit 24a, and transmits the blind control command to the electric blind 1 corresponding to the blind ID. Next, the process returns to step S1.
