Description

  The present invention relates to a transmittance management apparatus, a transmittance management method, a transmittance management program, and a transmittance management system of one or more partitions in which the transmittance of light changes.

  In recent years, a liquid crystal blind device that is opaque when not energized, but transparent when energized, has come to be used as a partition for dividing a window glass or a conference room of a building.

  In this regard, in Patent Document 1, as described in FIG. 6 of the document, a transparent electrode 102 and a transparent electrode 103 are attached to both surfaces of a composite film 101 in which two types of polymer materials and a liquid crystal material are dispersed. The transparent electrode 102 and the transparent electrode 103 are respectively formed by depositing the transparent conductive layer 102B and the transparent conductive layer 103B on the transparent film 102A and the transparent film 103A as a base, respectively. When the layer 102B and the transparent conductive layer 103B are in contact with the composite film 101 and a drive voltage is applied between the transparent electrode 102 and the transparent electrode 103 from the AC power supply 104, the light transmittance of the composite film 101 is increased. There is described a liquid crystal panel in which the light transmittance decreases when a drive voltage is not applied from the power supply 104.

First Embodiment
FIG. 1 is a schematic view showing an example of a conference management system according to the first embodiment of the present invention. As shown in FIG. 1, the conference management system 1 (transmittance management system) exemplarily manages one or more partitions 40 whose light transmittance changes, and reservation and progress of the conference.

The terminal device 30 and the partition 40 are installed, for example, in a part of a conference room as shown in FIGS. 6 (A) to 6 (E) described later.

  The conference management server 10 is connected to the dimming control device 20 by wired communication, and transmits a control signal for controlling a voltage applied to the partition 40 by the dimming control device 20 to the dimming control device 20. . That is, the conference management server 10 changes the light transmittance of the partition 40 via the dimming control device 20. The conference management server 10 may be connected to the dimming control device 20 by wireless communication.

  The conference management server 10 is connected to the terminal device 30 by wireless communication, and transmits information on the reservation status of the conference and the progress status of the conference to the terminal device 30. The conference management server 10 may be connected to the terminal device 30 by wired communication.

  The terminal device 30 may employ, for example, a tablet terminal device, but may be another device capable of outputting information, such as a smartphone. The number of terminal devices 30 is not particularly limited, and may be two or more. Furthermore, the number of partitions 40 is not particularly limited, and may be one or two or more.

  FIG. 2 is a schematic view showing an example of the configuration of the conference management server according to the first embodiment of the present invention. As illustrated in FIG. 2, the conference management server 10 illustratively manages conference reservation and progress, and executes an information process for managing the transmittance of the partition 40, and the information processing unit 11 And a recording unit 12 for recording various information used for the processing and the processing result.

  The conference management server 10 is configured by, for example, a server device including a computer system, and the software program is transferred from the recording unit 12 to the main memory and executed to operate the information processing unit 11 as a functional block. Also, the program may be downloaded from the outside of the conference management server 10 and provided, for example, via a predetermined network, or various computer readable programs such as CD-ROM and DVD-ROM. It may be provided by an information recording medium.

  The information processing unit 11 functionally includes an acquisition unit 13, a conference reservation management unit 14, a determination unit 15, and a control unit 16.

  The acquisition unit 13 acquires various types of information used for information processing. The acquisition unit 13 acquires, for example, conference reservation information from an information processing apparatus (not shown) owned by a conference participant connected to the conference management server 10. The meeting reservation information includes, for example, information such as the user for each meeting room, the date and time of use, deletion of the reservation, and change of the reservation.

  The acquisition unit 13 acquires time information related to the progress of a meeting (event). The acquiring unit 13 has, for example, a function as a time measuring unit, and may measure the current time as time information related to the progress of the conference, or may measure the elapsed time from the start time of the conference Good. Further, the acquisition unit 13 may acquire event start information indicating the start of a meeting (event) and event end information indicating the end of the meeting (event) from the terminal device 30 illustrated in FIG. 1.

  The conference reservation management unit 14 executes management of reservation of a conference, deletion of reservation, change of reservation, and the like based on the conference reservation information acquired by the acquisition unit 13.

  The determination unit 15 determines whether time information related to the progress of the meeting (event) satisfies a predetermined setting condition.

  The control unit 16 controls the partition 40 based on the determination result of the determination unit 15 so that the light transmittance of the partition 40 changes in multiple steps. The control unit 16 controls the timing of changing the light transmittance of at least one of the three partitions 40 to be different from the timing of changing the light transmittance of the other partitions 40, for example. The control unit 16 may also control the light transmittance of at least one of the three partitions 40 to be different from the light transmittance of the other partitions 40. Furthermore, the control unit 16 includes a form of controlling at least one partition 40 without necessarily controlling all three partitions 40.

  Here, multi-step control of light transmittance includes controlling light transmittance in multiple steps. Although five-step control is illustrated as an example of multi-step control in FIG. 7 described later, the present invention is not limited to this. Two- to four-step control may be performed, or control may be performed in six or more steps. Also, multi-step control may include control of an infinite number of steps. That is, instead of controlling in a stepwise manner as shown in FIG. 7, it may include one that changes the light transmittance smoothly (curvedly).

  The recording unit 12 records the conference reservation information acquired by the acquisition unit 13, time information related to the progress of the conference, event start information, and event end information. In addition, the recording unit 12 includes information for controlling the transmittance of light in the partition 40 shown in FIG. 1, for example, the transmittance of light in the partition 40 and an applied voltage required to control the transmittance. Associate and record. Furthermore, the recording unit 12 records, for each partition 40, timing to control the partition 40, for example, time information to control the partition 40 and elapsed time information of a conference.

  FIG. 3A is a schematic view showing an example of a partition using float glass according to the first embodiment of the present invention. FIG. 3 (B) is a schematic view showing an example of a partition using laminated glass according to an embodiment of the present invention. As shown in FIG. 3A, the partition 40 is illustratively at least one of the light control film 45 (film) configured to change the light transmittance in multiple steps, and the light control film 45. It may be configured to include a transparent plate 41 such as a plate glass that transmits light, which is disposed on the surface.

  As shown in FIG. 3 (B), the partition 40 is illustratively an intermediate film having adhesiveness and tackiness with a light control film 45 (film) configured to change light transmittance in multiple steps. A light transmitting transparent plate 41 (first light transmitting member) disposed on one side of the light control film 45 via the film 43 and the other side of the light control film 45 via the intermediate film 43 And the transparent plate 41 (2nd light transmissive member) which permeate | transmits light may be comprised.

Light control film 45 is not particularly limited as long as the light transmittance is configured to change, for example, a polymer dispersed liquid crystal (PDLC: P olymer D ispersed L iquid C rystal) or polymer network liquid crystal ( P NLC: may employ P olymer N etwork L iquid C rystal ) liquid crystal light control film and the like. The transparent plate 41 may be a member that transmits light, and for example, a plate glass may be employed as described above, but another plate-shaped resin or plastic may be employed. The intermediate film 43 may be, for example, a substance having adhesiveness and adhesiveness, and is, for example, a polymer film, and polyvinyl butyral (PVB) may be adopted, but polyvinyl chloride (PVC), polyethylene terephthalate (PET) And polypropylene (PP) may be employed. The intermediate film 43 may include a special material having a sound insulation effect.

  According to the partition 40 using this laminated glass, since the light control film 45 is covered with the plurality of transparent plates 41 via the intermediate film 43, it becomes hard to be damaged by an impact and thus the strength of the partition 40 can be increased. it can.

  In addition, by using the interlayer 43 having the sound insulation effect, the voice of the event participant is absorbed by the interlayer 43. Therefore, it is possible to prevent the voice from leaking from the event hall and to improve the confidentiality of the event.

  The partitions 40 are installed at various positions in the conference room. For example, the partition 40 is shaped according to various installation positions, such as center glass, side glass, or double glass.

  FIG. 4A is a view showing a state of light scattering in the light control film when a large voltage is applied. FIG. 4B is a view showing the state of light scattering in the light control film when a small voltage is applied. As shown in FIGS. 4A and 4B, the light control film 45 is exemplarily disposed on both surfaces of the liquid crystal layer 455 whose light transmittance changes in multiple steps and the liquid crystal layer 455. And a polymer film 451 disposed on the liquid crystal layer 455 with the transparent conductive film 453 interposed therebetween.

  The liquid crystal layer 455 includes, for example, liquid crystal 4551 and a polymer 4553. As shown in FIG. 4A, when a large voltage is applied to the liquid crystal layer 455, the molecules of the liquid crystal 4551 align in a certain direction. Since light is transmitted through the liquid crystal layer 455, the partition 40 shown in FIGS. 1 and 3 is controlled to be in a transparent state.

  On the other hand, as shown in FIG. 4B, when a small voltage is applied to the liquid crystal layer 455 or no voltage is applied at all, the orientations of the molecules of the liquid crystal 4551 become apart, and the incident light is scattered. Accordingly, the liquid crystal layer 455 transmits no light or hardly transmits light, so that the partition 40 shown in FIGS. 1 and 3 is controlled to be in an opaque state. Here, the opaque state is a state in which light can not be transmitted in the partition 40, and the entire surface of the partition 40 may be in a state of white light control, or light control in black or another color. It may be in the state.

  As described above, by controlling the voltage applied to the liquid crystal layer 455, the light transmission state of the partition 40 can be controlled. Here, the change in light transmittance is not something like 0% or 100%, for example, but includes one that can take an intermediate value of these values. The method of controlling the light transmission state in the partition 40 is not limited to this, and the partition 40 having the light control film 45 that can be controlled in the opaque state when energized and in the transparent state when deenergized may be employed.

  The polymer film 451 may be any substance having adhesiveness and adhesiveness, and for example, polyvinyl butyral (PVB) may be adopted, and polyvinyl chloride (PVC), polyethylene terephthalate (PET), polypropylene (PP) or the like may be used. It may be adopted.

(Transmittance management processing)
An example of the transmittance management process according to the first embodiment of the present invention will be described using FIGS. 5 to 7. FIG. 5 is a flowchart showing an example of the transmittance management process according to the first embodiment of the present invention. FIG. 6 is a conceptual diagram showing an example of the transmittance management process according to the first embodiment of the present invention, and more specifically, a conceptual diagram showing how the transmittance of the partition changes as the conference progresses. It is.

(Step S1)
The acquisition unit 13 of the conference management server 10 illustrated in FIG. 2 acquires conference schedule information, for example, conference reservation information such as scheduled start time (12:00) and scheduled end time (13:00) of the conference.

(Step S2)
The acquisition unit 13 acquires check-in information (event start information) indicating the start of a meeting (event). For example, as shown in FIG. 6A, when the start time of the conference is 12:00, conference participants gather in the conference room. Then, although the conference participant is not illustrated in FIG. 6, the check-in information is transmitted from the terminal device 30 to the conference management server 10 by operating the terminal device 30 illustrated in FIG. 1 installed in the conference room. Be done.

(Step S3)
The determination unit 15 illustrated in FIG. 2 determines that the conference has started based on the check-in information acquired by the acquisition unit 13, and the control unit 16 determines that FIG. 6 (B) is based on the determination result of the determination unit 15. The partition 40 is controlled so as to minimize the light transmittance in the partition 40 shown. That is, when it is determined that the conference has started, the control unit 16 controls the partition 40 to be in an opaque state immediately.

  When the meeting starts, it is possible to prevent the appearance of the inside of the meeting room from being visible from the outside quickly.

  The determination unit 15 may determine that the meeting has started at the scheduled start time, and the control unit 16 may control the partition 40 at the scheduled start time so that the light transmittance of the partition 40 becomes minimum. .

(Step S4)
When the acquisition unit 13 does not acquire checkout information (event end information) indicating the end of the meeting (event), the process proceeds to step S5. Step S5 will be described later.

  On the other hand, when the acquisition unit 13 acquires checkout information indicating the end of the meeting, the process proceeds to step S7. For example, when the conference ends much earlier than the scheduled end time, the conference participant operates the terminal device 30 (not shown in FIG. 6) shown in FIG. 1 installed in the conference room, Checkout information is transmitted from the terminal device 30 to the conference management server 10.

  The determination unit 15 illustrated in FIG. 2 determines that the meeting is ended based on the checkout information acquired by the acquisition unit 13, and the control unit 16 determines whether the meeting is completed based on the determination result of the determination unit 15 in FIG. The partition 40 is controlled so that the light transmittance in the partition 40 shown is maximized. That is, when it is determined that the conference is ended, the control unit 16 controls the partition 40 to be in a transparent state immediately.

  When the conference ends, the partition 40 is made transparent by force. Then, users other than the meeting participants can confirm that the meeting has ended earlier than scheduled. Then, immediately after this meeting, it is possible to change the reservation so that the meeting reserved in the same meeting room can be started earlier than the scheduled time.

(Step S5)
The determination unit 15 determines whether time information related to the progress of the meeting (event) satisfies a predetermined setting condition. If the time information related to the progress of the conference does not satisfy the predetermined setting condition, the process returns to step S4, and if the time information satisfies, the process proceeds to step S6.

  For example, the determination unit 15 determines whether 15 minutes before the end of the conference (12: 45). More specifically, the determination unit 15 determines whether or not the current time as time information related to the progress of the conference has reached the set time (12:45). When it is determined that the current time has reached the set time (the predetermined setting condition is satisfied), the process proceeds to step S6.

  In addition, the determination unit 15 may determine whether an elapsed time from the start of the meeting as time information related to the progress of the meeting exceeds a set elapsed time (45 minutes). Then, when it is determined that the elapsed time of the conference exceeds the set elapsed time (the predetermined setting condition is satisfied), the process proceeds to step S6.

  The determination unit 15 may adopt other determination processing. In addition, the determination unit 15 may execute the determination process periodically (for example, at one minute intervals) (batch process) or at another interval. Further, the determination unit 15 may execute the determination process at any timing.

(Step S6)
The control unit 16 illustrated in FIG. 2 controls the partition 40 so that the light transmittance of the partition 40 changes in multiple stages when the time information related to the progress of the conference satisfies a predetermined setting condition.

  FIG. 7 is a graph showing an example of the relationship between the elapsed time of a conference and the transmittance of light in a partition according to an embodiment of the present invention. As shown in FIG. 7, the control unit 16 shown in FIG. 2 controls the partition 40 so that the light transmittance in the partition 40 changes in five steps. Here, in order to control in five steps, for example, five setting times of 12:45, 12:48, 12:51, 12:54 and 12:57 are preset, and the recording unit 12 shown in FIG. It is recorded for each partition. Also for the set elapsed time, similarly, for example, five of 45 minutes, 48 minutes, 51 minutes, 54 minutes and 57 minutes are set in advance and recorded in the recording unit 12 shown in FIG. 2 for each partition.

First, when the determination unit 15 determines that it is 15 minutes before the end of the conference (12:45), the control unit 16 controls the light transmittance to S1 as the first stage. As the light transmittance of the partition 40 increases, as shown in FIG. 6C, the appearance of the conference room can be visually recognized from the outside, though it is slightly.
Subsequently, as shown in FIG. 7, when the determination unit 15 determines that it is 12 minutes before the end of the conference (12:48), the control unit 16 controls the light transmittance to S2 as a second step. If, on the other hand, the determining unit 15 determines that the time is 9 minutes before the end of the conference (12: 51), the light transmittance is controlled to S3 in the third step.

  Then, as shown in FIG. 6 (D) and FIG. 7, when the determination unit 15 determines that it is six minutes before the end of the conference (12: 54), the control unit 16 determines the light transmittance as the fourth step. Control to S4. At this stage, the appearance of the conference room can be easily viewed from the outside.

  Finally, the control unit 16 controls the light transmittance to S5 at the fifth stage, when the determination unit 15 determines that it is three minutes before the end of the conference (12: 57). Here, for example, the light transmittance S5 is a maximum value, which indicates that the partition 40 is in a transparent state. Then, as shown in FIG. 6E, at the end of the conference (13:00), the state of the conference room can be completely viewed from the outside.

  As shown in FIG. 7, when the control unit 16 determines that the determination unit 15 is 15 minutes before the end of the conference (12:45), the light transmittance is relatively set to S1 as the first step. It is changed greatly, and is changed gradually in the subsequent transmittances S2 to S5. According to this form, it is possible to gradually control the opaque partition as the conference reaches the end of the conference, so that the conference participants in the conference room are approaching the end of the conference. Can be notified.

(Step S7)
As shown in FIG. 6E and FIG. 7, when it is determined that the conference is over, the control unit 16 controls the partition 40 to be in the transparent state.

  According to the first embodiment described above, it is determined whether the time information related to the progress of the meeting satisfies the predetermined setting condition, and the light transmittance of the partition 40 is multistaged based on the determination result. Control to change to Therefore, since the light transmittance of the partition 40 changes in accordance with the progress of the conference, it is possible to provide convenience which has not existed conventionally. For example, if the partition 40 is controlled to be opaque at the beginning of the meeting and transparent at the end of the meeting, the meeting participants can be appropriately notified that the end of the meeting is approaching, and smooth from the meeting room. Encourage them to leave.

Second Embodiment
FIG. 8 is a schematic view showing an example of a conference management system according to the second embodiment of the present invention. The difference between the conference management system 1 shown in FIG. 8 according to the second embodiment and the conference management system 1 shown in FIG. 1 according to the first embodiment is that the conference management system 1 shown in FIG. Instead of the conference management server 10 and the terminal device 30 included in the management system 1, a switch device 50 is provided. In the following, points different from the first embodiment will be mainly described.

  The switch device 50 is connected to the dimming control device 20 in a wired communication, and transmits a control signal for controlling a voltage applied to the partition 40 by the dimming control device 20 to the dimming control device 20. That is, the switch device 50 changes the light transmittance of the partition 40 through the dimming control device 20. The switch device 50 may be wirelessly connected to the dimming control device 20.

  Although not shown, the switch device 50 is provided with, for example, a switch unit for inputting a start and an end of a conference, and when the switch unit is operated and check-in information indicating the start of the conference is input, the switch device 50 controls that the partition 40 immediately becomes opaque when it is determined that the conference has started. Also, when the switch unit is operated and checkout information indicating the end of the conference is input, the switch device 50 controls the partition 40 to be in an opaque state immediately when it is determined that the conference is over. .

  Also, the switch device 50 has, for example, a timer function, and may measure an elapsed time from the start time of the conference as time information related to the progress of the conference. Then, the switching device 50 may control the partition 40 so that the light transmittance of the partition 40 changes in multiple stages when the elapsed time exceeds the set elapsed time.

  According to the second embodiment described above, since the light transmittance of the partition 40 changes in accordance with the progress of the conference, in addition to being able to provide convenience that did not exist conventionally, As compared with the conference management system 1 shown in FIG. 1 of the embodiment, the conference management server 10 and the terminal device 30 do not need to be provided, so the system can be configured simply and at low cost.

Third Embodiment
In the third embodiment, the transmittance of light in a partition composed of a plurality of partitions is controlled. FIGS. 9A and 9B are schematic diagrams showing an example of a partition composed of a plurality of partitions. As shown in FIGS. 9A and 9B, the partition 40 is configured to include partitions 401, 403, and 405, for example.

  The control unit 16 illustrated in FIG. 2 controls the timing of changing the light transmittance of at least one of the plurality of partitions to be different from the timing of changing the light transmittance of other partitions. As shown in FIGS. 9A and 9B, for example, the control unit 16 sets the timing of changing the light transmittance of the partition 403 different from the timing of changing the light transmittance of the other partitions 401 and 405. You may control as follows. More specifically, when all of the partitions 401, 403, and 405 are in the opaque state, the timing of changing the light transmittance of the partition 403 is different from the timing of changing the light transmittance of the other partitions 401 and 405. You may control so that it will be in a transparent state early. In addition, the control unit 16 may control the two partitions 401 and 403 at different timings from the other partitions 405.

  According to the third embodiment described above, the timing of changing the light transmittance of at least one of the plurality of partitions 401, 403, and 405 in the partition 40 changes the light transmittance of other partitions. Since the timing can be controlled to be different, the timing of changing the light transmittance can be controlled for each area in the partition 40. Therefore, it is possible to more clearly notify the meeting participants in the meeting room that the end of the meeting is approaching.

  The control unit 16 may control the light transmittance of at least one of the plurality of partitions to be different from the light transmittance of the other partitions. For example, the control unit 16 may control the light transmittance of at least one of the plurality of partitions 401, 403, and 405 in the partition 40 to be different from the light transmittance of another partition.

  According to this aspect, the light transmittance can be changed in various variations for each area in the partition 40. Therefore, it is possible to more clearly notify the meeting participants in the meeting room that the end of the meeting is approaching.

  The control unit 16 does not necessarily need to control all the partitions 401, 403, and 405. For example, when all the partitions 401, 403, and 405 are in the opaque state, only the partition 403 is in the transparent state. You may control as follows.

  In FIG. 5, the determination process (step S4) as to whether or not the checkout information is acquired is performed before step S5, but is not limited thereto, and may be performed after step S5. For example, even when the checkout information is acquired while the transmittance is controlled in multiple stages in step S6, the control unit forcibly controls the partition so as to make the partition transparent. Good.
