performed by the entry / exit management unit 12 and the entry / exit monitoring unit 21. The
conference room entry and exit process shows the procedure and process when the user enters
and leaves the conference room. When the meeting room reservation system 1 is powered on
and becomes operable, the process proceeds to step D1. The door 23 of the conference room 20
is basically locked or locked. Although it is possible for an employee to enter the meeting room
20, a person who is not an employee can not enter the room. The speaker 36 and the locking
unit 22 are controlled so that information handled in the conference room 20 is not leaked to a
person who is not an employee but is not planning to participate in the conference.
[0081]
In step D1, the user determines whether he / she wants to enter the meeting room. If it is desired
to enter the meeting room, the process proceeds to step D2, and if it is not desired to enter the
meeting room, the process for entering and leaving the meeting room is ended. In step D2 which
is an acquisition step, the user causes the entry / exit monitoring unit 21 of the meeting room
that the user wishes to enter to read the employee ID card. In step D3, the entry and exit
monitoring unit 21 reads the employee code from the employee ID card, and transmits the read
employee code to the entry and exit management unit 12 via the network 50. In step D4, upon
receipt of the employee code, the room entry / exit management unit 12 collates the received
employee code with the employee information 61 stored by the employee information recording
unit 13.
[0082]
In step D5, it is determined whether the received employee code is registered. The room entry /
exit management unit 12 determines that the received employee code is registered if the
09-05-2019
26
employee information 61 stored by the employee information recording unit 13 has an employee
code that matches the received employee code as a result of collation. Go to step D6. As a result
of the collation, when the employee code corresponding to the received employee code is not in
the employee information 61 stored by the employee information recording unit 13, it is
determined that the received employee code is not registered, and the conference room entering
and leaving process is ended. Do.
[0083]
In step D6, the room entry / exit management unit 12 collates the received employee code with
the meeting room reservation information 62 stored by the meeting room reservation unit 11. In
step D7, it is determined whether the received employee code is registered in the meeting room
reservation information 62 at the current time. As a result of checking, if there is an employee
code that matches the received employee code in the meeting room reservation information 62
stored by the meeting room reservation unit 11, the received employee code corresponds to the
current meeting room. It determines that it is registered in the reservation information 62, and
proceeds to step D8. If the employee code that matches the received employee code is not in the
meeting room reservation information 62 stored by the meeting room reservation unit 11, it is
determined that the received employee code is not registered in the meeting room reservation
information 62 at the current time. Proceed to step D10. Steps D4 to D7 are determination steps.
[0084]
In step D8, the entry and exit management unit 12 transmits a signal for unlocking the door to
the entry and exit monitoring unit 21 of the conference room, that is, the entry and exit
monitoring unit 21 that has transmitted the received employee code. In step D9, the entry and
exit monitoring unit 21 instructs the locking unit 22 to unlock the door, and the conference room
entry and exit processing is ended. In step D10, the entry and exit management unit 12 transmits
a release confirmation signal to the monitor control unit 34. When the entry / exit management
unit 12 transmits the cancellation confirmation signal to the monitor control unit 34, the position
level of the person of the received employee code is read from the employee information 61, and
the position level information indicating the read position level is cancellation confirmation
signal Send along with
[0085]
09-05-2019
27
In step D11, the room entry / exit management unit 12 determines whether the monitor control
unit 34 has sent back a release enable signal. When receiving the release enable signal
transmitted from the monitor control unit 34, the entry / exit management unit 12 determines
that the release enable signal is returned from the monitor control unit 34, and proceeds to step
D8. When receiving the release impossible signal transmitted from the monitor control unit 34 or
when a predetermined time-out time has elapsed, it is determined that the release enable signal
is not returned from the monitor control unit 34, and the conference room entering and leaving
process is ended.
[0086]
FIG. 17 is a flowchart showing the procedure of the control setting process performed by the
user and the monitor control unit 34. For example, when the setting button provided on the
remote control is operated or the setting icon displayed on the display unit 31 is clicked by the
mouse or the keyboard, the process moves to step E1.
[0087]
In step E1, the monitor control unit 34 displays the control setting screen 75 on the display unit
31. In step E2, the user determines whether to end the setting. When the setting is finished, the
process goes to step E7, and when the setting is not finished, the process goes to step E3. In step
E3, the user determines whether or not to set mute. When setting to mute, the process proceeds
to step E8, and when not set to mute, the process proceeds to step E3.
[0088]
In step E4, the user determines whether or not to set "output only on the right side". If "output
only on the right side" is set, the process proceeds to step E10, and if "output only on the right
side" is not set, the process proceeds to step E5. For example, when the door of the meeting room
is on the left side toward the display unit 31, if setting is made so that the sound is output only
from the right side at the time of setting, a third party unrelated to the meeting is unexpectedly
left side. Even if the user enters the meeting room from a certain door, it is possible to prevent a
third party from hearing the sound output from the speaker 36. In step E5, the user determines
whether to set "output only on the left side". When "output only on the left side" is set, the
09-05-2019
28
process proceeds to step E12. When "output only on the left side" is not set, the process proceeds
to step E6. In step E6, the user determines whether or not locking is to be set. When the lock is
set, the process proceeds to step E14. When the lock is not set, the process returns to step E2.
[0089]
In step E7, the user operates the close button 755 of the control setting screen 75 to close the
control setting screen 75, and ends the control setting process. In step E8, the user selects a
circle in the audio mute setting field 751 of the control setting screen 75. At step E9, the monitor
control unit 34 stores "mute" as the setting method of the control setting information, and
returns to step E2. In step E10, "output only on the right side" is selected. That is, the user selects
a circle in the right output setting field 752 of the control setting screen 75. At step E11, the
monitor control unit 34 stores right as the setting method of the control setting information,
and returns to step E2. In step E12, "output only on the left side" is selected. That is, the user
selects a circle in the left output setting field 753 of the control setting screen 75. At step E13,
the monitor control unit 34 stores left as the setting method of the control setting
information, and returns to step E2. In step E14, "lock" is selected. That is, the user selects a
circle in the lock setting field 754 of the control setting screen 75. In step E15, the monitor
control unit 34 stores locking as the setting method of the control setting information, and
returns to step E2.
[0090]
FIG. 18 is a flowchart showing the procedure of the first monitor control process performed by
the monitor control unit 34. The first monitor control process performs control of sound output
restriction and door unlocking. For example, when the power of the monitor 30 is turned on and
becomes operable in order to conduct a conference, the process proceeds to step F1.
[0091]
In step F1, it is determined whether an unlock confirmation signal has been received. When the
monitor control unit 34 receives the unlock confirmation signal from the entry / exit
management unit 12, the monitor control unit 34 receives the post level information transmitted
simultaneously, proceeds to step F2, and does not receive the unlock confirmation signal from
the entry / exit management unit 12. And go to step F4. In step F2, after the second monitor
09-05-2019
29
control process is performed, the process proceeds to step F3. In step F3, after the third monitor
control process is performed, the process proceeds to step F4. In step F4, it is determined
whether or not to end monitor control. When the conference is over, locking becomes
unnecessary, or when the power of the monitor 30 is turned off, it is determined that the monitor
control is to be finished, and the first monitor control process is finished. When the conference is
over, when the locking becomes unnecessary, or when the power of the monitor 30 is not cut off,
it is determined that the monitor control is not finished, and the process returns to step F1.
[0092]
FIG. 19 is a flowchart showing the procedure of the second monitor control process included in
the first monitor control process. In the process of step F2 of the flowchart shown in FIG. 18, the
process moves to step G1.
[0093]
In step G1, the monitor control unit 34 displays the warning screen 76 on the monitor, that is,
the display unit 31. In step G2, it is determined whether or not admission is permitted. When the
Ok button 762 of the warning screen 76 is operated, the monitor control unit 34 determines that
entry is permitted, and the process proceeds to step G3. When the NG button 763 is operated, it
is determined that entry is not permitted. Return to step F1 shown in FIG.
[0094]
In step G3, it is determined whether data is displayed on the monitor. If display data is displayed
on the display unit 31, the monitor control unit 34 determines that the data is displayed on the
monitor, and proceeds to step G4. If the display data is not displayed on the display unit 31, It is
determined that data is not displayed on the monitor, and the second monitor control process is
ended.
[0095]
In step G4, it is determined whether there is any data displayed on the monitor that matches the
09-05-2019
30
item display data in the display data restriction information 63. The monitor control unit 34
sets the file name that matches the file name of the display data displayed on the monitor to the
file name of the display data item of the display data restriction information 63 stored in the
storage device of the monitor 30. If it exists, it is determined that there is data displayed on the
monitor that matches the item "display data" in the display data restriction information 63, and
the process proceeds to step G5. If the file name that matches the file name of the display data
displayed on the monitor does not appear in the file name of the item "Display data" in the
display data restriction information 63, the data displayed on the monitor will be displayed. It is
determined that there is nothing that matches the item of display data in the data restriction
information 63, and the second monitor control process is ended.
[0096]
In step G5, the monitor control unit 34 stores the display level of the largest value among the
display levels of the matching display data as the maximum display level in the storage
device of the monitor 30, and performs the second monitor control process. finish.
[0097]
FIG. 20 is a flowchart showing the procedure of the third monitor control process included in the
first monitor control process.
In the process of step F3 of the flowchart shown in FIG. 18, the process moves to step H1.
[0098]
In step H1, the monitor control unit 34 determines whether the "setting method" of the control
setting information is "silence". If the "setting method" is "mute", the process proceeds to step H7,
and if the "setting method" is not "mute", the process proceeds to step H2. In step H2, the
monitor control unit 34 determines whether the setting method of the control setting
information is right . If the setting method is right , the process proceeds to step H8,
and if the setting method is not right , the process proceeds to step H3. In step H3, the
monitor control unit 34 determines whether the setting method of the control setting
information is left side . If the "setting method" is "left side", the process proceeds to step H9,
and if the "setting method" is not "left side", the process proceeds to step H4. In step H4, the
monitor control unit 34 determines whether the "setting method" of the control setting
09-05-2019
31
information is "locking". If the "setting method" is "locking", the process proceeds to step H5, and
if the "setting method" is not "locking", the third monitor control process ends.
[0099]
In step H5, it is determined whether the post level of the entry person is greater than the
"maximum display level". If the post level indicated by the post level information received in step
F1 shown in FIG. 18 is greater than the maximum display level stored in the storage device
of the monitor 30, the monitor control unit 34 is permitted to browse Then, it is determined that
the post level of the entry person is greater than the "maximum display level", and the process
proceeds to step H10. If the post level indicated by the post level information received in step F1
shown in FIG. 18 is not larger than the maximum display level stored in the storage device of
the monitor 30, that is, if viewing is not permitted, It is determined that the job title level is not
larger than the "maximum display level", and the process proceeds to step H6. In step H6, the
monitor control unit 34 transmits an unlocking impossible signal to the entry / exit
management unit 12, and ends the third monitor control process. The unlocking impossible
signal is a signal indicating that the door 23 is not unlocked.
[0100]
In step H7, the monitor control unit 34 instructs the control unit 35 to stop the output of the
sound from the speaker 36. When instructed by the monitor control unit 34 to stop the output of
the sound from the speaker 36, the control unit 35 controls the speaker 36 to stop the output of
the sound from the speaker 36, and proceeds to step H10. In step H8, the monitor control unit
34 instructs the control unit 35 to allow the sound from the speaker 36 to be heard only on the
right side toward the monitor. When the control unit 35 receives an instruction from the monitor
control unit 34 that the sound from the speaker 36 can be heard only on the right side toward
the monitor, the control unit 35 controls the speaker 36 and the speaker 36 only on the right
side toward the monitor. To make it possible to hear the sound from and go to step H10. Steps
H1 to H3 and H7 to H9 are control steps.
[0101]
In step H9, the monitor control unit 34 instructs the control unit 35 to allow the sound from the
speaker 36 to be heard only on the left side of the monitor. When the control unit 35 receives an
09-05-2019
32
instruction from the monitor control unit 34 so that the sound from the speaker 36 can be heard
only on the left side toward the monitor, the control unit 35 controls the speaker 36, as shown in
FIG. As shown in c), the sound from the speaker 36 can be heard only on the left side of the
monitor, and the process goes to step H10. In step H10, the monitor control unit 34 transmits an
unlockable signal to the entry / exit management unit 12, and ends the third monitor control
process. The unlockable signal is a signal indicating that the door 23 is to be unlocked.
[0102]
As described above, directional sound is output by the speaker 36 and held by the meeting room
reservation unit 11 in the meeting room 20 in which the speaker 36 is installed among the
employee codes for identifying each person. The employee code of the person who is permitted
to attend the meeting is stored as a participant list. The employee code of the person entering the
conference room 20 is acquired by the entry and exit monitoring unit 21, and the employee code
acquired by the entry and exit monitoring unit 21 is stored in the conference room reservation
unit 11 by the entry and exit management unit 12. It is determined whether any one of the
participant lists is matched. Then, the monitor control unit 34 determines that the determination
result determined by the entry and exit management unit 12 matches the employee code
acquired by the entry and exit monitoring unit 21 with any of the participant lists stored in the
meeting room reservation unit 11 When not indicating, it controls to limit the output of the
sound by the speaker 36.
[0103]
Therefore, even if the third party enters the conference room 20 or the like, it is possible to
prevent the information leakage due to the sound to the third party who has entered the room
without interrupting the conference.
[0104]
Furthermore, the speaker 36 is configured by a plurality of speakers 36, and the monitor control
unit 34 stops the output of the sound by the speaker 36 that outputs the sound to the region of
the plurality of speakers 36 where the propagation of the sound is to be restricted. Therefore, it
is not necessary to change the directivity in each speaker 36, and it is not necessary to use an
expensive speaker which can change the directivity direction.
[0105]
Furthermore, the directivity direction in which sound is output is controlled by outputting an
09-05-2019
33
ultrasonic wave by the speaker 36, and the monitor control unit 34 does not output sound to the
area where the propagation of the sound is to be restricted. Because the pointing direction of the
sound to be output is controlled, the region where the sound is not transmitted can be controlled
more accurately.
[0106]
Furthermore, the entry and exit monitoring unit 21 is provided at a position close to the door for
entry and exit of each conference room 20, and the area where the sound propagation should be
restricted is the employee code of the person entering the conference room 20. Since the area
including the position where a person enters from the door close to the position where the
acquired entry and exit monitoring unit 21 is provided, the propagation of sound to the person
who entered the room from the door adjacent to the entry and exit monitoring unit 21 is
stopped. It is possible to prevent the leakage of information by sound to the person who entered
the room.
[0107]
Furthermore, in step D2 of the flowchart shown in FIG. 16, the entry / exit monitoring unit 21
that acquires the employee code of the person acquires the employee code of the person who
enters the meeting room 20.
[0108]
At steps D4 to D7 shown in FIG. 16, the employee code acquired at step D2 of the flowchart
shown in FIG. 16 outputs the directional sound among the employee codes for identifying each
person. Whether the employee code of the person who is permitted to attend the meeting held in
the meeting room 20 in which the group is installed matches the participant list stored in the
meeting room reservation unit 11 as a participant list It is determined whether or not.
[0109]
Then, in steps H1 to H3 and H7 to H9 shown in FIG. 20, the determination result determined in
steps D4 to D7 shown in FIG. 16 corresponds to the employee code acquired in step D2 of the
flowchart shown in FIG. When it is indicated that none of the participant lists stored in the
conference room reservation unit 11 matches, control is performed to limit the output of the
sound by the speaker 36.
[0110]
Therefore, by applying the sound output method according to the present invention, even if a
09-05-2019
34
third party enters a meeting room etc., leakage of information due to sound to the third party
who has entered the room is prevented without interrupting the conference. Can.
