Description

[Technical Field]

[0001] The present invention relates to a shared space terminal and a shared space management system using the same. [Background technology]

[0002] Patent Document 1 discloses a resource reservation system for a conference room. This system has a server system including a conference room management server that stores reservation information related to resource reservations, and conference room terminals that acquire and display the reservation information from the server system. The conference room terminals are installed for each resource, change according to setting information that sets the display method of the reservation information, and display the reservation information acquired from the conference room management server. In response to a request from the conference management server, the conference room terminals turn on the power of electronic devices at the start time of the conference and turn off the power of the electronic devices at the end time of the conference. The electronic devices are various office devices that can be used in the conference room, such as an electronic whiteboard, a multifunction printer, a projector, digital signage, or a digital camera.

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-87424 Summary of the Invention [Problem to be solved by the invention]

[0004] In systems related to shared spaces such as rental conference rooms, the usage fee is typically determined based on the reserved usage time. Therefore, unauthorized use outside of these hours without paying the usage fee should be prevented. In the system of Patent Document 1, for example, once the reserved time for the conference room has passed, the office equipment in the conference room is turned off and becomes unavailable, allowing users to recognize the end of the conference and the fact that the conference can no longer be continued smoothly. However, users can remain in the conference room and continue the conference even if they are unable to use the office equipment. Therefore, even if the above system disables the use of office equipment outside of the reserved time, it does not necessarily ensure that unauthorized use of the conference room outside of these hours can be prevented. Furthermore, the above system requires the relevant office equipment to be configured for remote on / off operation, making its implementation a high hurdle.

[0005] Therefore, the objective of the present invention is to provide a shared space terminal and a shared space management system that have high manageability to reliably prevent unauthorized use of shared spaces outside of business hours and are easy to install, eliminating the need for additional function settings on existing equipment. [Means for solving the problem]

[0006] According to a first aspect of the present invention, a shared space terminal placed within a shared space comprises a wireless communication unit that receives, from a lighting command unit of a cloud server, a turn-on command generated at a first predetermined time immediately before the start time of a shared space reservation and a turn-off command generated at a second predetermined time immediately after the end time of a shared space reservation, a switch circuit for connecting or disconnecting the power supply wiring of lighting equipment installed in the shared space, and a switch control unit that controls the switch circuit to connect the power supply wiring in response to receiving a turn-on command and controls the switch circuit to disconnect the power supply wiring in response to receiving a turn-off command.

[0007] According to a second aspect of the present invention, a shared space terminal placed within a shared space comprises a wireless communication unit that receives reservation information including the reservation start time and reservation end time of the shared space from a cloud server, a lighting command unit that generates a turn-on command at a first predetermined time immediately before the reservation start time and generates an turn-off command at a second predetermined time immediately after the reservation end time, a switch circuit for connecting or disconnecting the power supply wiring of the lighting equipment within the shared space, and a switch control unit that controls the switch circuit to connect the power supply wiring in response to the generation of the turn-on command and controls the switch circuit to disconnect the power supply wiring in response to the generation of the turn-off command.

[0008] According to the first and second aspects, when reserving a shared space, the shared space terminal connects the power supply wiring to turn on the lighting devices just before the reservation start time and disconnects the power supply wiring to turn off the lighting devices just after the reservation end time. This effectively turns off the lights in the shared space outside of the reserved time, preventing users from continuing to use the space illegally. Therefore, a shared space terminal is realized that has high manageability to reliably prevent unauthorized use of the shared space outside of reserved hours and is highly easy to install, as it does not require additional function settings for existing devices. In the first aspect, the shared space terminal is realized with a simple configuration. In the second aspect, sequential wireless communication is not required for the lighting device on and off operations, so even if a communication failure occurs during use of the shared space, the effects of the above-mentioned on / off operations can be reliably achieved. In this disclosure, "just before" and "just after" a specific time are considered to include times substantially the same as the specific time.

[0009] In the first and second aspects, it is preferable that the difference in time between the reservation end time and the second specified time is 30 minutes or less. If this difference in time is 0 minutes, high manageability can be achieved by disabling use after the reservation time. On the other hand, if this difference in time is more than 0 minutes and 30 minutes or less, a certain level of manageability can be ensured while providing a certain amount of grace period for use after the reservation time, making the shared space user-friendly. In consideration of achieving both manageability and user-friendliness, it is particularly preferable that the difference in time is 5 minutes or less.

[0010] In the first and second aspects, it is preferable that the difference in time between the first predetermined time and the reservation start time is 30 minutes or less. If this difference in time is 0 minutes, use before the reservation time is prohibited, thereby achieving high manageability. On the other hand, if this difference in time is more than 0 minutes and 30 minutes or less, some use before the reservation time, such as users entering and gathering, is permitted, thereby reducing the number of users waiting outside the shared space and eliminating causes such as noise to the surrounding area and obstructions to traffic. This makes it possible to achieve smooth operation of the shared space while ensuring manageability. In consideration of both manageability and smooth operation, it is particularly preferable that the difference in time be 10 minutes or less.

[0011] In the first and second aspects, the lighting command unit is configured to generate a turn-off command or a turn-on command to temporarily reverse the on / off state of the lighting devices at a predetermined exit guidance time before the end of the reservation. This causes the lighting devices to temporarily blink, and this blinking visually and intuitively notifies the user that the end of the reservation is approaching, and can prompt the user to prepare to leave the room as the reservation time ends.

[0012] In the first and second aspects, the lighting command unit is configured to generate a turn-off command temporarily at the reserved start time, causing the lighting device to temporarily blink, thereby visually and intuitively informing the user of the reserved start time.

[0013] In the first and second aspects, the shared space terminal further includes a switch button that accepts a press or touch operation by a user of the shared space and outputs a switch operation signal. The lighting command unit is configured to generate a turn-off command in response to the switch operation signal if the lighting device is on during a period from the reservation start time or a first predetermined time onwards and before the reservation end time or a second predetermined time, and to generate a turn-on command in response to the switch operation signal if the lighting device is off. This allows manual operation by the user to be accepted during the usage time, improving the convenience of the shared space.

[0014] In the first and second aspects, the lighting command unit is configured to generate a lighting command for a predetermined provisional lighting period in response to a switch operation signal during a period before a first predetermined time or a period after a second predetermined time. This allows the shared space to be used temporarily outside of opening hours for purposes such as patrolling by a manager (staff member) of the shared space or retrieving forgotten items by users, thereby increasing the convenience and safety of the shared space. Given the purpose of temporary use outside of opening hours, the provisional lighting period is preferably between 10 seconds and 1 minute.

[0015] In the first and second aspects, the lighting command unit is configured to generate a lighting command for a predetermined forced lighting period in response to a specific operation signal generated in response to a specific operation on the console screen during a period before a first predetermined time or a period after a second predetermined time. This allows cleaning staff, maintenance staff, and other workers to work outside of normal working hours in the shared space, and enables the manager to manage the working hours of these staff.

[0016] A third aspect of the present invention is a shared space management system including the shared space terminal of the first or second aspect and the cloud server. Because the shared space management system includes the shared space terminal, it has high manageability that reliably prevents unauthorized use of the shared space outside of business hours, and is highly easy to install, eliminating the need for additional function settings on existing equipment.

[0017] In the third aspect, the shared space terminal further includes an environmental sensor that detects a predetermined environmental component in the shared space and outputs the environmental level, and a second wireless communication unit that transmits the environmental level to the cloud server. The cloud server includes a ventilation command unit that generates an operation command when the environmental level exceeds a predetermined threshold. The switch circuit is configured to connect or disconnect the power supply wiring of the ventilation fan installed in the shared space, and the switch control unit controls the switch circuit to connect the power supply wiring in response to the operation command received from the ventilation command unit via the wireless communication unit. This operates the ventilation fan in response to a deterioration in the environmental level, maintaining the comfort of the shared space.

[0018] In the third aspect, the environmental component is, for example, carbon dioxide. This prevents deterioration of the sanitary environment of the shared space due to overcrowding of users. Furthermore, the environmental component is, for example, carbon monoxide, nitrogen dioxide, or a volatile organic compound. This prevents deterioration of the sanitary environment of the shared space due to factors other than the users' bodies. [Brief explanation of the drawings]

[0020] First Embodiment FIG. 1 shows a block diagram of a shared space management system 1 (hereinafter referred to as "system 1") according to a first embodiment of the present invention. The system 1 includes a shared space terminal 2 arranged in a shared space S and a cloud server 4 (cloud service) wirelessly connected to the shared space terminal 2 via a wireless LAN router 3. In this embodiment, the shared space S is a rental conference room, and lighting equipment 5 and a ventilation fan 6 are installed in the shared space S. The system 1 can cooperate with mobile devices 7 of users present in the shared space S and an administrator terminal 8 that may be located remotely from the shared space S, via a communication network N such as the Internet. The system 1 can also cooperate with an appropriate schedule management app A, such as Google Calendar (registered trademark), via the communication network N. Note that while FIG. 1 shows a pair of a shared space S and a shared space terminal 2, the system 1 may include multiple pairs of shared spaces S and shared space terminals 2.

[0021] In summary, in the system 1, for reserving use of the shared space S, the reservation start time and reservation end time for the usage time are specified in the cloud server 4. The shared space terminal 2 connects the power supply wiring of the lighting device 5 to turn on the lighting device 5 just before the reservation start time, and disconnects the power supply wiring of the lighting device 5 to turn off the lighting device 5 just after the reservation end time.

[0022] FIG. 2 shows a perspective view of the housing 20 of the shared space terminal 2. The housing 20 has a longitudinal direction in the horizontal direction and a triangular prism shape with a cross section perpendicular to the longitudinal direction that is an approximately vertical triangle. The housing 20 has a bottom surface 20a, a back surface 20b perpendicular to the bottom surface 20a, and a front surface 20c connecting the bottom surface 20a and the back surface 20b. The connecting portions of the bottom surface 20a, the back surface 20b, and the front surface 20c are continuous with rounded edges. The two side surfaces 20d and 20e, which are the horizontal ends of the housing 20, form an approximately vertical triangle. The longitudinal length of the housing 20 is approximately 30 cm to 40 cm, preferably 35.8 cm ± 1 cm. The height (vertical length) of the housing 20 is approximately 15 cm to 20 cm, preferably 17.1 cm ± 1 cm. The depth (thickness) of the housing 20 is approximately 8 cm to 10 cm, and preferably 9.3 cm ± 0.5 cm. However, the external dimensions of the housing 20 are not limited to the above. The shared space terminal 2 can be a wall-mounted type, a tabletop type, or the like, so a wall-mounting structure may be provided on the back surface 20b, and legs (projections on the four corners, anti-slip rubber on the four corners, etc.) may be provided on the bottom surface 20a.

[0023] 3 shows a front view (front surface 20c) of the shared space terminal 2. The shared space terminal 2 has a console screen 21, a physical switch unit 22, and a sensor unit 23. In this embodiment, the console screen 21, the physical switch unit 22, and the sensor unit 23 are arranged from left to right on the front surface 20c, but the arrangement or placement of these is not limited to that shown in the figure.

[0024] The console screen 21 is a liquid crystal display, an OLED display, or the like, and displays necessary information according to the situation and accepts touch operations by the user. Regarding reservation information for the shared space S, the console screen 21 displays a current time display 21a, a reservation end time display 21b, an extension use guide display 21c, and a remaining time display 21d (hereinafter, these are also referred to as objects 21a to 21d). Regarding environmental information for the shared space S, the console screen 21 displays a noise level display 21e, a CO2 concentration display 21f (or a humidity display 21h, not shown), and a temperature display 21g (hereinafter, these are also referred to as objects 21e to 21h). Regarding operation information for the lighting devices 5 and the ventilation fan 6, the console screen 21 displays a lighting software switch 21i and a ventilation software switch 21j as icons (hereinafter, these are also referred to as objects 21i and 21j). Furthermore, the console screen 21 displays an image code display 21k (hereinafter, also referred to as "object 21k").

[0025] The extended use guide display 21c displays the maximum available time for extended use of the shared space S where the shared space terminal 2 is located. This maximum available time is assumed to be the time of the day. If extended use of the shared space S is not possible, the extended use guide display 21c displays "Not possible."

[0026] The value of remaining time display 21d is the value obtained by subtracting the value of current time display 21a from the value of reservation end time display 21b, and is displayed when the remaining time is 60 minutes or less, with the remaining time (unit: minutes) displayed as a countdown. Furthermore, remaining time display 21d is displayed together with a predetermined pie chart as shown in the figure. The circumference of this graph corresponds to 60 minutes. The moving end (bottom end of the thick circumference) indicating the current value of the graph moves counterclockwise and ends at the top position (0 o'clock position). Note that the moving end indicating the current value may also move clockwise and end at the top position (12 o'clock position). Furthermore, when the remaining time is 1 minute or less, the circumference may correspond to 60 seconds, and the remaining time (unit: seconds) may be displayed as a countdown.

[0027] The lighting soft switch 21i is displayed in reverse black and white depending on whether the lighting device 5 is on or off. For example, when the lighting device 5 is on, a black-based display is applied, and when the lighting device 5 is off, a white-based display is applied. Similarly, the ventilation soft switch 21j is displayed in reverse black and white depending on whether the ventilation fan 6 is on or off. For example, when the ventilation fan 6 is on, a black-based display is applied, and when the ventilation fan 6 is off, a white-based display is applied.

[0028] The image code displayed in the image code display 21k is preferably a two-dimensional code such as QR Code (registered trademark), Data Matrix (registered trademark), or VeriCode (registered trademark), and in this embodiment, a QR code is used. However, this embodiment can also be implemented if the image code is a one-dimensional code such as a barcode. Also, as shown in the figure, the image code display 21k may include a display that prompts the mobile terminal 7 to read the image code. Other objects will be described later.

[0029] The physical switch unit 22 includes a lighting physical switch 22a and a ventilation physical switch 22b. The lighting physical switch 22a outputs a lighting operation signal in response to a user's pressing operation, and the ventilation physical switch 22b outputs a ventilation operation signal in response to a user's pressing operation. These operation signals are transmitted to the cloud server 4. The lighting physical switch 22a is provided with an indicator lamp 22c such as an LED that indicates the current operation state (on or off) of the lighting device 5, and the ventilation physical switch 22b is provided with an indicator lamp 22d such as an LED that indicates the current operation state (on or off) of the ventilation fan 6. The on / off of the indicator lamp 22c may correspond to the on / off of the lighting device 5 or may correspond to the off / on of the lighting device 5. The on / off of the indicator lamp 22d may correspond to the operation / stop of the ventilation fan 6 or may correspond to the stop / on of the ventilation fan 6.

[0030] By definition, the lighting software switch 21i, the lighting physical switch 22a, the ventilation software switch 21j, and the ventilation physical switch 22b are collectively referred to as switch buttons. Also, the touch operation on the lighting software switch 21i, the press operation on the lighting physical switch 22a, the touch operation on the ventilation software switch 21j, and the press operation on the ventilation physical switch 22b are collectively referred to as switch operations, and the signals output by the switch operations are collectively referred to as switch operation signals.

[0031] The sensor unit 23 includes an environmental sensor 23a (strictly speaking, the illustrated example shows an air intake hole for the environmental sensor 23a) and a human presence sensor 23b. The environmental sensor 23a detects and outputs an environmental level of the air obtained from the air intake hole. The environmental sensor 23a and the human presence sensor 23b will be described in detail later.

[0032] Returning to Figure 1, we will explain each part of the shared space terminal 2. The shared space terminal 2 has a console screen 21, a physical switch unit 22, a sensor unit 23, a wireless communication unit 24, a switch circuit 25, a control unit 26, a memory 27, and a speaker 28. The console screen 21, the physical switch unit 22, the sensor unit 23, the wireless communication unit 24, the switch circuit 25, the control unit 26, the memory 27, and the speaker 28 are appropriately interconnected via a bus or the like in a manner that allows the exchange of necessary signals, data, or power.

[0033] The environmental sensor 23a of the sensor unit 23 includes a noise sensor 231, a temperature and humidity sensor 232, a CO2 sensor 233, and an air quality (IAQ (Indoor Air Quality)) sensor 234. The environmental sensor 23a identifies various environmental levels within the shared space S. Note that a barometric pressure sensor that detects atmospheric pressure may also be used as the environmental sensor. A detection signal indicating the detected environmental level is transmitted from the wireless communication unit 24 (wireless communication unit 243) to the cloud server 4 via the wireless LAN router 3.

[0034] Noise sensor 231 detects sound pressure and outputs a noise level (decibels) converted from the sound pressure (hereinafter referred to as "detected noise level"). Noise sensor 231 may be configured to detect sound pressure in a predetermined frequency range (e.g., approximately 100 to 2000 Hz) such as the frequency range of human voice. A detection signal indicating the detected noise level is transmitted from wireless communication unit 243 to cloud server 4 via wireless LAN router 3.

[0035] The temperature and humidity sensor 232 detects the temperature and humidity and outputs the temperature value and humidity value (hereinafter referred to as the "detected temperature," "detected humidity," or "detected temperature and humidity"). The temperature and humidity sensor 232 may be a temperature sensor that detects only the temperature and outputs a temperature value, or a humidity sensor that detects only the humidity and outputs a humidity value. Detection signals indicating the detected temperature and detected humidity are transmitted from the wireless communication unit 243 to the cloud server 4 via the wireless LAN router 3.

[0036] The CO2 sensor 233 detects carbon dioxide (CO2) using the NDIR (Non Dispersive InfraRed) method and outputs the CO2 concentration (hereinafter referred to as the "detected CO2 concentration"). An increase in CO2 concentration can be caused by human breathing, and can therefore be an indicator of crowded conditions. A detection signal indicating the detected CO2 concentration is transmitted from the wireless communication unit 243 to the cloud server 4 via the wireless LAN router 3.

[0037] The IAQ sensor 234 detects pollutants and outputs their concentration (hereinafter referred to as the "detected pollution level"). The detected pollutants are carbon monoxide (CO), nitrogen dioxide (NO2), or volatile organic compounds (VOCs). The sources of the pollutants include, in particular, cigarette smoke, formaldehyde, asbestos, dust, exhaust fumes, VOCs from carpets, paints, adhesives, furniture, building materials, etc., pet dander, mold, bacteria, pesticides, herbicides, etc. A detection signal indicating the detected pollution level is transmitted from the wireless communication unit 243 to the cloud server 4 via the wireless LAN router 3.

[0038] The human presence sensor 23b of the sensor unit 23 is an infrared human presence sensor that detects the presence / absence of a human body in the shared space S (or its specified detection area). The human presence sensor 23b outputs a presence signal when it detects the presence of a human body, and outputs an absence signal in other cases (i.e., when no human body is present). The presence signal / absence signal may be a high-level signal / low-level signal, a low-level signal / high-level signal, signal output / no signal, signal output / no signal, or a UART signal. In this disclosure, the presence signal / absence signal is collectively referred to as a human presence detection signal. The human presence detection signal is transmitted from the wireless communication unit 243 to the cloud server 4 via the wireless LAN router 3.

[0039] The wireless communication unit 24 includes wireless communication units 241 to 243. The wireless communication units 241, 242, and 243 correspond to the console screen 21, the physical switch unit 22, and the sensor unit 23, respectively. The wireless communication units 241 to 243 may be integrated into one wireless communication unit, or may be three separate wireless communication units (the latter is adopted in this embodiment). Each of the wireless communication units 241 to 243 wirelessly communicates with the wireless LAN router 3 under communication control of the control unit 26 or the like, or autonomously. In this embodiment, each of the wireless communication units 241 to 243 is a Wi-Fi unit for performing Wi-Fi (registered trademark) communication, and is, for example, a Wi-Fi device operating at 2.4 GHz (802.11b / g / n).

[0040] The wireless communication unit 241 transmits an operation signal (screen operation signal) resulting from an operation on the console screen 21 to the cloud server 4. This operation signal includes a switch operation signal from the lighting software switch 21i and the ventilation fan software switch 21j. The wireless communication unit 241 also receives a console command and an audio output command from the cloud server 4. The wireless communication unit 242 transmits a switch operation signal (physical switch operation signal) from the lighting physical switch 22a or the ventilation physical switch 22b to the cloud server 4. The wireless communication unit 242 also receives switch commands (turn on command, turn off command, operate command, and stop command) described below from the cloud server 4. The wireless communication unit 243 transmits a detection signal (sensor detection signal) from the sensor unit 23 to the cloud server 4.

[0041] In this way, providing separate Wi-Fi units for the console screen 21, the physical switch unit 22, and the sensor unit 23 makes it possible to diagnose the wireless communication status. For example, if the cloud server 4 does not receive some of the screen operation signals, physical switch operation signals, and sensor detection signals, it is presumed that the wireless LAN router 3 and the communication network N are normal, but that there is a malfunction in the wireless communication unit corresponding to the unreceived signal or in the part to which it belongs. Furthermore, if the cloud server 4 does not receive all of the screen operation signals, physical switch operation signals, and sensor detection signals, it is presumed that there is a malfunction in the wireless LAN router 3 or a communication failure in the communication network N.

[0042] The switch circuit 25 is connected between an alternating current power supply AC (for example, a commercial power supply) and the lighting device 5 and the ventilation fan 6. The switch circuit 25 connects / disconnects the power supply wiring between the alternating current power supply AC and the lighting device 5, and connects / disconnects the power supply wiring between the alternating current power supply AC and the ventilation fan 6, under the control of the control unit 26 (switch control unit 262).

[0043] 4 shows a circuit diagram of a wiring example for the switch circuit 25. The switch circuit 25 is made up of a relay switch, and has terminals 251 to 254 on the AC side of the AC power supply, a terminal 255 connected to a lighting device 5, and a terminal 256 connected to a ventilation fan 6. The terminals 251, 252, and 253 are interconnected. The path between the terminal 252 and the terminal 255 is opened and closed by a switch SW5, and the path between the terminal 251 and the terminal 256 is opened and closed by a switch SW6.

[0044] Wiring L1 on the ungrounded side of the AC power supply AC is connected to the ungrounded (hot) terminal of a plug receptacle 91 (so-called outlet). Wiring L2 on the grounded side of the AC power supply AC is connected to one connection terminal of the lighting device 5, one connection terminal of the ventilation fan 6, and the grounded (cold) terminal of the plug receptacle 91. The other connection terminal of the lighting device 5 is connected to terminal 255 via wiring L5, and the other connection terminal of the ventilation fan 6 is connected to terminal 256 via wiring L6. Terminal 251 is connected to the ungrounded terminal of the attachment plug 92 via wiring L3, and terminal 254 is connected to the grounded terminal of the attachment plug 92 via wiring L4. The following description will be given assuming that the attachment plug 92 is correctly connected to the plug receptacle 91.

[0045] The control unit 26 (switch control unit 262) individually controls the opening and closing of the switch SW5 and the opening and closing of the switch SW6. When the switch SW5 is turned on (closed), the lighting device 5 receives power from the AC power source via the power supply wiring (L1, L3, L5, and L2) and turns on. On the other hand, when the switch SW5 is turned off (open), the lighting device 5 is cut off from the AC power source AC and turns off. Similarly, when the switch SW6 is turned on (closed), the ventilation fan 6 receives power from the AC power source AC via the power supply wiring (L1, L3, L6, and L2) and operates. On the other hand, when the switch SW6 is turned off (open), the ventilation fan 6 is cut off from the AC power source AC and stops operating.

[0046] FIG. 5 shows a circuit diagram of another wiring example for the switch circuit 25. Components similar to those in FIG. 4 are designated by the same reference numerals, and redundant explanations will be omitted. A single-phase conductor 94 is connected to the switch circuit 25. The ungrounded side wiring L1 and the grounded side wiring L2 are connected to an AC power source AC via a single-phase breaker 93. The wiring L1 is connected to a terminal 251 of the switch circuit 25 and a terminal 941 of the single-phase conductor. The wiring L2 is connected to one terminal of the exhaust fan 6, a terminal 254 of the switch circuit 25, and an input terminal 942 and a control terminal 944 of the single-phase conductor 94. The other terminal of the exhaust fan 6 is connected to a terminal 256 via a wiring L6. The terminal 255 is connected to a control terminal 943 of the single-phase conductor 94 via a wiring L5. The output terminals 945 and 946 of the single-phase conductor 94 are connected to the lighting device 5 via wiring L51 and L52. The following description will be given on the assumption that the single-phase breaker 93 is in an on (energized) state.

[0047] The control unit 26 (switch control unit 262) individually controls the opening and closing of the switch SW5 and the opening and closing of the switch SW6. When the switch SW5 is turned on, the control terminals 943 and 944 of the single-phase conductor 94 are supplied with power from the AC power source AC, and the input terminal 941 and the output terminal 945 and the input terminal 942 and the output terminal 946 are connected. As a result, the lighting device 5 is supplied with power from the AC power source AC via the power supply wiring (L1, L51, L2, and L52) and turns on. On the other hand, when the switch SW5 is turned off, the control terminal 943 of the single-phase conductor 94 is not supplied with power, and the input terminals 941 and 942 are disconnected from the output terminals 945 and 946. The lighting device 5 is thus cut off from the AC power source AC and turned off. Furthermore, as in the case of FIG. 4, when the switch SW6 is turned on, the ventilation fan 6 is supplied with power from the AC power source AC via the power supply wiring (L1, L6, and L2) and operates. On the other hand, when the switch SW6 is turned off, the ventilation fan 6 is disconnected from the AC power supply AC and stops.

[0048] As described above, in the configuration of Figure 5, the load current to the lighting devices 5 does not pass through the switch circuit 25, so it is possible to turn on / off a relatively large group of lighting devices without increasing the current capacity of the switch circuit 25 or the shared space terminal 2. In addition, by appropriately selecting and expanding the conductor 94, it is also possible to wire outlets and control the on / off of small to large air conditioners, etc. Note that while the block diagram of Figure 1 corresponds to the circuit configuration of Figure 4, a person skilled in the art should be able to apply the circuit configuration of Figure 5 to the block diagram of Figure 1 instead of the circuit configuration of Figure 4.

[0049] FIG. 6A shows a rear view (rear view 20b) and a side view (side view 20d) of the shared space terminal 2 (corresponding to the wiring in FIG. 4). FIG. 6B shows a partial cross-sectional side view of the shared space terminal 2 when the rear view 20b is attached to a wall W. The rear view 20b is provided with a recess 20g for wiring and a hole 20h for wall attachment. The recess 20g is tapered, and its depth (horizontal recess depth) increases from the upper side to the lower side (toward the bottom view 20a). Therefore, the bottom view 20a has a notch. As shown in FIG. 6B, the wall W has wall holes Wh for the wall switches of the lighting device 5 and the ventilation fan 6, and the shared space terminal 2 is attached to the wall W so that the recess 20g corresponds to the wall hole Wh. When the shared space terminal 2 is attached to the wall W in this way, the lower part of the recess 20g is open within the bottom view 20a, and the upper part of the recess 20g is blocked by the wall W and the rear view 20b.

[0050] Connection terminal blocks 25a and 25b are disposed in recess 20g. Connection terminal block 25a has terminals 251 and 254 (not shown) on the AC power supply side, and connection terminal block 25b has terminals 255 and 256 (not shown) on the load side. Therefore, in the case of the wiring shown in FIG. 4, wires L3 and L4 are inserted and connected to connection terminal block 25a, and wires L5 and L6 are connected to connection terminal block 25b. As shown in FIG. 6B, wires L3 and L4 extend from connection terminal block 25a through the notch in bottom surface 20a to the outside and below wall surface W, and wires L5 and L6 extend from connection terminal block 25b through wall hole Wh to the inside of wall surface W. Note that wires L3 and L4 may also be routed inside wall surface W. In the case of the wiring shown in FIG. 5, wires L1 and L2 are inserted and connected to connection terminal block 25a, and wires L5 and L6 are connected to connection terminal block 25b. 5, the wiring L1 and L2 may be wired inside the wall W. In the wiring shown in FIG. 4, if there are multiple systems of lighting devices 5, the wiring L5 of each system is connected together to terminal 255 (not shown) of the connection terminal block 25b. In the wiring shown in FIG. 5, if there are multiple systems of lighting devices 5, the wiring L51 and L52 of each system are connected to output terminals 945 and 946 of the single-phase conductor 94, and therefore only the wiring L5 is connected to terminal 255 (not shown) of the connection terminal block 25b of the switch circuit 25.

[0051] The recess 20g is also provided with a power connector 29 (outlet) for supplying operating power to the shared space terminal 2. A DC power jack (not shown) of an AC / DC adapter is inserted into the power connector 29. This supplies DC voltage to the shared space terminal 2, and operating power is supplied to each component via an appropriate constant voltage circuit (not shown) inside the housing 20. In this embodiment, the shared space terminal 2 is configured to operate on DC power, but if an AC / DC converter is installed inside the shared space terminal 2, AC voltage (for example, commercial power from a wall outlet) is supplied to the power connector 29. In this case, the power connector 29 can be omitted and an AC cable can be directly connected to the shared space terminal 2. This AC cable and the wiring L3 and L4 can be physically or electrically bundled and wired as a single AC cable. Alternatively, a battery can be installed inside the housing 20, and operating power for the shared space terminal 2 can be supplied from that battery. In this case, the power connector 29 is not necessary.

[0052] Returning to FIG. 1, the components of the shared space terminal 2 will be further described. The control unit 26 includes a console control unit 261, a switch control unit 262, and an audio output control unit 263. The control unit 26 includes a CPU such as a microprocessor or microcomputer and its peripheral circuits. While one control unit 26 is illustrated in this embodiment, the control unit 26 may be divided into blocks corresponding to the console screen 21, the physical switch unit 22, and the sensor unit 23. In addition to the functions of the above-mentioned components, the control unit 26 may also perform various general functions (such as a clock function, a timing function, a communication control function, and an arithmetic processing function) as appropriate. The memory 27 includes a ROM for storing programs and the like, and a RAM for temporarily storing data, programs, and the like. Although the memory 27 is included in the control unit 26 in FIG. 1, the memory 27 may be located outside the control unit 26.

[0053] The console control unit 261 displays a screen on the console screen 21 based on a console command acquired from the cloud server 4 via the wireless LAN router 3 and the wireless communication unit 241. The console command specifies the selection of which of the objects 21a to 21k to display, the display content of each object to be displayed (numerical values, black and white inversion, etc.), the placement of the selected object, etc.

[0054] The switch control unit 262 controls the opening and closing of each switch in the switch circuit 25 based on switch commands acquired from the cloud server 4 via the wireless LAN router 3 and the wireless communication unit 242. The switch commands include a turn-on command to turn on the lighting device 5 by turning on the switch SW5, a turn-off command to turn off the switch SW5 to turn off the lighting device 5, an operation command to turn on the switch SW6 to operate the ventilation fan 6, and a stop command to turn off the switch SW6 to stop the ventilation fan 6.

[0055] Audio output control unit 263 controls audio output from speaker 28 based on an audio output command acquired from cloud server 4 via wireless LAN router 3 and one of wireless communication units 241 to 243 (for example, wireless communication unit 241, the same applies below). The audio output command includes a guidance audio output command for a guidance message and a warning audio output command for a warning message, as will be described in detail later.

[0056] The wireless LAN router 3 is configured to be wirelessly connectable to the shared space terminal 2 (wireless communication units 241-243) and the mobile terminal 7 (communication unit 71), and is configured to be able to communicate with the cloud server 4 (communication unit 41) via a communication network N such as the Internet. The wireless LAN router 3, the shared space terminal 2, and the mobile terminal 7 are connected via Wi-Fi communication (2.4 GHz). In other words, the wireless LAN router 3 is a Wi-Fi router capable of Wi-Fi communication with the wireless communication units 241-243. The wireless LAN router 3 and the cloud server 4 are connected via 3G, 4G, LTE, etc., and a modem may be connected between the wireless LAN router 3 and the communication network N as necessary.

[0057] The cloud server 4 has a communication unit 41, a processing unit 42, and a database 43. The communication unit 41 can communicate with the communication network N via a wired or wireless connection. That is, the cloud server 4 can communicate with the administrator terminal 8 and the schedule management application A via the communication network N using the communication unit 41, and can communicate with the shared space terminal 2 and the mobile terminal 7 via the communication network N and the wireless LAN router 3. The database 43 stores data contained in signals transmitted from the shared space terminal 2, the mobile terminal 7, etc.

[0058] Processing unit 42 includes a reservation management unit 420, a display processing unit 421, a lighting command unit 422, a ventilation command unit 423, a warning processing unit 424, a voice guidance processing unit 425, and a data processing unit 426. Processing unit 42 can also execute general cloud server processing functions such as overall control of each unit in cloud server 4 and communication control of communication unit 41. In other words, processing unit 42 can appropriately execute various general functions (such as a clock function, a timing function, a communication control function, and an arithmetic processing function) other than the functions of each unit 420 to 426.

[0059] The reservation management unit 420 provides a reservation website for the share space S to the user's mobile device or personal computer (PC) and determines reservation information from user input on the reservation website. Therefore, the reservation management unit 420 holds current and future reservation information for the share space S. The reservation management unit 420 can perform time management as described in the present disclosure in cooperation with an external schedule management application A. However, such a schedule management application may be included in the processing unit 42. The reservation management unit 420 obtains the reservation start time ts and reservation end time te of the reserved use time from the reservation information, and generates time t0 associated with the reservation start time ts, times t1 to t4 associated with the reservation end time te, and time ta as needed. Times t0 to t4 and ta are described below.

[0060] The time t0 associated with the reservation start time ts is the lighting time for turning on the lighting device 5 before the reservation start time ts. The difference time T0-s from the time t0 to the reservation start time ts is, for example, about 0 to 30 minutes, preferably about 0 to 10 minutes (for example, more than 0 to about 10 minutes), and more preferably about 5 to 10 minutes. When the difference time T0-s is 0 minutes, the shared space S cannot be used before the usage time, achieving high manageability. On the other hand, when the difference time T0-s is more than 0 minutes, some users are permitted to enter and gather even before the usage time, reducing the number of users waiting outside the shared space S (which may cause noise in the surrounding area and disrupt the movement of other users). This ensures manageability while achieving smooth operation of the shared space S.

[0061] The time t1 associated with the reservation end time te is a notice of the end of the reservation that warns the user of the arrival of the reservation end time te before the reservation end time te. The difference in time T1-e from time t1 to the reservation end time te is approximately 5 to 15 minutes, and preferably approximately 10 minutes. This is to prompt users to wrap up the conference and prepare to leave smoothly.

[0062] The time t2 accompanying the reservation end time te is an exit guidance time to encourage users to leave (or exit, the same applies below) the room before the reservation end time te. The difference time T2-e from time t2 to the reservation end time te is about 1 to 10 minutes, and preferably about 5 minutes. This encourages users to prepare to leave the room smoothly.

[0063] The time t3 accompanying the reservation end time te is an end notification time that notifies the user of the arrival of the reservation time before the reservation end time te. The difference time T3-e from time t3 to the reservation end time te is about 0 to 1 minute, preferably about 1 minute. This is to prompt the user to leave the room immediately.

[0064] The time t4 associated with the reservation end time te is the time at which the lighting devices 5 are turned off after the reservation end time te. The difference time Te-4 from the reservation end time te to the turn-off time t4 is approximately 0 to 30 minutes, preferably approximately 0 to 5 minutes (for example, more than 0 to approximately 5 minutes), and more preferably approximately 5 minutes. The difference time Te-4 is desirably 0 minutes (i.e., te=t4) to prevent fraudulent use after the reservation time. However, if there are no subsequent reservations, a slight grace period may be set, and the time may be set to approximately 30 minutes or less to ensure manageability while making the shared space S user-friendly.

[0065] The time ta associated with the reservation end time te is an extension notification time to encourage reservations for extended use before the reservation end time te. However, if the shared space S is reserved after the reservation end time te, the time ta will not be generated, or even if it is generated, it will not be used. The difference in time Ta-e from the time ta to the reservation end time te should be around 15 minutes, and it is desirable that it be before the notice end time t1.

[0066] The display processing unit 421 generates a console command based on the information on each time and whether or not extension is possible generated by the reservation management unit 420, a switch operation signal from the console screen 21 or the physical switch unit 22, and a detection signal from the sensor unit 23. This console command forms objects 21a to 21j on the console screen 21. The display command unit 421 also generates a console command for a mobile terminal for the mobile terminal 7 that captured the image code display 21k from the console screen 21. The image code displayed on the image code display 21k is an image code specific to the reservation time (reservation start time ts to reservation end time te). In other words, different image codes are applied and displayed for different reservation times. Therefore, a given image code is valid only during the corresponding reservation time.

[0067] Furthermore, the display processing unit 421 generates a console command to put the console screen 21 into standby mode (for example, blackout) outside of the usage hours of the shared space S. Even outside of usage hours, if a human presence signal is transmitted from the human presence sensor 23b of the shared space terminal 2 or an operation signal indicating the detection of a touch on the console screen 21 is transmitted, the display processing unit 421 generates a console command to display a predetermined standby screen. The console command is transmitted from the communication unit 41 to the shared space terminal 2 (wireless communication unit 241), and the console command for the mobile terminal is transmitted from the communication unit 41 to the mobile terminal 7 (communication unit 71).

[0068] 7A and 7B show an example of a console screen 21 of a shared space terminal 2 that has received a console command, and an example of a display screen 74 of a mobile terminal 7 that has received a corresponding mobile terminal console command. As shown in FIG. 7A, the console screen 21 displays the following objects: a current time display 21a, an extended use guide display 21c, a remaining time display 21d, a noise level display 21e, a CO2 concentration display 21f, a temperature display 21g, a lighting software switch 21i, a ventilation software switch 21j, and an image code display 21k. Meanwhile, as shown in FIG. 7B, the display screen 74 displays the following objects: a current time display 74a, an extended use guide display 74c, a remaining time display 74d, a noise level display 74e, a CO2 concentration display 74f, a temperature display 74g, a lighting software switch 74i, and a ventilation software switch 74j. An object 74m for other functions (e.g., air conditioning control) may also be displayed as an option.

[0069] Here, the shapes of objects 21a, 21c, 21d, 21e, 21f, 21g, 21i, and 21j are identical (similar) to the shapes of corresponding objects 74a, 74c, 74d, 74e, 74f, 74g, 74i, and 74j. Although not shown in the examples of FIGS. 7A and 7B, when reservation end time display 21b or humidity display 21h is displayed on console screen 21, an object of the same shape for reservation end time display or humidity display is also displayed on display screen 74. This gives users a stronger sense of link to console screen 21 or shared space terminal 2 via display screen 74 or mobile terminal 7, improving operability.

[0070] The display screen 74 of the mobile terminal 7 is a touch panel that accepts touch operations by the user. Operations on each object on the display screen 74 (particularly, switching on the lighting software switch 74i or the ventilation software switch 74j) are synchronized with operations on the corresponding object on the console screen 21 (particularly, switching on the lighting software switch 21i or the ventilation software switch 21j). This allows the user to operate each object without touching the console screen 21. This avoids indirect contact between an unspecified number of users via the console screen 21 (including indirect contact with users using the facility at different times), which is preferable from a hygienic perspective, such as preventing infection. Furthermore, touching the extended use guide display 74c on the display screen 74 displays a screen for making an extended use reservation and payment. This allows the user to easily complete the procedure for extending use using the mobile terminal 7.

[0071] When the mobile terminal 7 is held in a landscape orientation (when the longitudinal direction of the display screen 74 is oriented horizontally), the arrangement or placement of the objects 74a to 74j may be the same as the arrangement or placement of the objects 21a to 21j. Furthermore, when the mobile terminal 7 is a tablet terminal, the arrangement or placement of the objects 74a to 74j may be the same as the arrangement or placement of the objects 21a to 21j regardless of the orientation in which the tablet terminal is held. Alternatively, unlike the present embodiment, when the console screen 21 is a portrait-oriented screen, when the mobile terminal 7 is held in a portrait orientation (when the longitudinal direction of the display screen 74 is oriented vertically), the arrangement or placement of the objects 74a to 74j may be the same as the arrangement or placement of the objects 21a to 21j. This further enhances the user's sense of link between the display screen 74 or the mobile terminal 7 and the console screen 21 or the shared space terminal 2, further improving operability.

[0072] The lighting command unit 422 generates a light-on command and a light-off command based on each time generated by the reservation management unit 420 or a switch operation signal sent from the shared space terminal 2 (lighting software switch 21i or lighting physical switch 22a). The generated light-on command or light-off command is sent from the communication unit 41 to the shared space terminal 2 (wireless communication unit 242).

[0073] Specifically, at the lighting time t0, the lighting command unit 422 generates a lighting command. At the reservation start time ts, the lighting command unit 422 generates a short-time off command. As a result, the switch control unit 262 temporarily turns off the switch SW5 of the switch circuit 25, so that the lighting device 5 is temporarily turned off, i.e., blinks or blinks. This blinking or blinking allows the user to visually and intuitively recognize the arrival of the reservation start time ts. At the exit guidance time t2, the lighting command unit 422 temporarily generates a short-time off command or a short-time on command to reverse the on / off state of the lighting device 5. Specifically, if the lighting device 5 is in an on state, a temporary off command is generated, and if the lighting device 5 is in an off state (such as when a projector is being used), a temporary on command is generated. This blinking or blinking allows the user to visually and intuitively recognize the imminent reservation end time te. These flashing or blinking may be performed one time, or may be performed multiple times in succession (i.e., multiple times of going back and forth between turning on and off). At light-off time t4, the illumination command unit 422 generates a light-off command.

[0074] During the usage time, the lighting command unit 422 generates a turn-off command in response to the switch operation signal when the lighting device 5 is in the on state, and generates a turn-on command in response to the switch operation signal when the lighting device 5 is in the off state (i.e., reverses between on and off). Note that the period during the usage time refers to the period from the turn-on time t0 or the reservation start time ts to the reservation end time te or the turn-off time t4, and the period during the reservation time refers to the period from the reservation start time ts to the reservation end time te.

[0075] On the other hand, during periods outside of the usage hours, the lighting command unit 422 generates a temporary lighting command for a provisional lighting period in response to a switch operation signal. The term "outside of the usage hours" refers to the period before the lighting-on time t0 or after the lighting-off time t4, and the term "outside of the reservation hours" refers to the period before the reservation start time ts or after the reservation end time te. This provisional lighting period is, for example, between 10 seconds and 1 minute, preferably between 20 and 40 seconds, and more preferably about 30 seconds. This provisional lighting period provides temporary lighting for the administrator (staff) of the shared space S to patrol the shared space or for users to retrieve items left behind. Here, the display processing unit 421 may display a countdown of the remaining time of the provisional lighting period on the console screen 21 (for example, by the remaining time display 21d). This allows staff or temporary users to recognize that the current lighting is provisional. Furthermore, since staff or temporary users know the grace period until the lights are turned off, they can act calmly within that grace period.

[0076] The lighting command unit 422 can also be configured to generate a lighting command for a predetermined forced lighting period during periods outside of usage hours in response to a specific operation signal generated in response to a specific operation on the console screen 21. The specific operation is, for example, a touch operation on a predetermined location on the console screen 21. This touch operation on a predetermined location may be defined as a touch operation on a single blank space, a simultaneous touch operation on multiple blank spaces, multiple objects, or a combination of blank spaces and objects, or continuous touch operations within a short period of time. This allows cleaning staff, maintenance staff, and other workers to perform work outside of working hours (cleaning, maintenance, etc.) in the shared space S. When the lights are turned off, a lighting-off command is generated by touching the lighting soft switch 21i, just as when the lights are turned off during usage hours. The administrator can manage the working hours of the workers using the logs of the lighting and off commands in this case on the administrator terminal 8.

[0077] The ventilation command unit 423 generates an operation command or a stop command based on the environmental level indicated by a switch operation signal sent from the shared space terminal 2 (ventilation software switch 21j or ventilation physical switch 22b) or a signal sent from the shared space terminal 2 (environment sensor 23a). Alternatively, regardless of the presence or absence of a switch operation signal from the shared space terminal 2 or the environmental level, the ventilation command unit 423 may generate an operation command periodically (for example, every 30 minutes) for a predetermined period (for example, 5 minutes) as regular ventilation. The generated operation command or stop command is sent from the communication unit 41 to the shared space terminal 2 (wireless communication unit 242).

[0078] In response to the switch operation signal, the ventilation command unit 423 generates a stop command if the ventilation fan 6 is in an operating state, and generates an operation command if the ventilation fan 6 is in a stopped state (i.e., reverses the operating and stopped states).

[0079] Furthermore, the ventilation command unit 423 generates an activation command when the detected CO2 level from the CO2 sensor 233 exceeds a CO2 threshold (e.g., 1000 ppm), and then generates a stop command when the detected CO2 level from the CO2 sensor 233 falls below the CO2 threshold. Note that, in order to avoid frequent repetition of activation and deactivation of the ventilation fan 6, the ventilation command unit 423 may generate an activation command when the detected CO2 level exceeds a CO2 rising threshold, and generate a stop command when the detected CO2 level falls below a CO2 falling threshold (CO2 rising threshold > CO2 falling threshold). Alternatively, the detection interval or the detection signal transmission interval of the CO2 sensor 233 may be set relatively long.

[0080] Furthermore, the ventilation command unit 423 generates an operation command when the detected pollution level from the IAQ sensor 234 exceeds a pollution threshold (e.g., 1100 ppb for VOCs), and then generates a stop command when the detected pollution level from the IAQ sensor 234 falls below the pollution threshold. Note that, in order to avoid frequent repetition of operation and stopping of the ventilation fan 6, the ventilation command unit 423 may generate an operation command when the detected pollution level exceeds a pollution increase threshold, and generate a stop command when the detected pollution level falls below a pollution decrease threshold (pollution increase threshold>pollution decrease threshold). Alternatively, the detection interval or the detection signal transmission interval of the IAQ sensor 234 may be set relatively long.

[0081] The warning processing unit 424 generates a warning audio output command to issue a warning message from the speaker 28 of the shared space terminal 2 when the detected noise level indicated by the signal transmitted from the noise sensor 231 satisfies the noise warning condition. The warning audio output command is a warning message such as "Please be quieter!". The warning message may also be accompanied by a message based on an objective indicator, such as "Exceeds XX decibels," thereby ensuring the persuasiveness of the warning. The generated audio output command is transmitted from the communication unit 41 to the shared space terminal 2 (wireless communication unit 241). The audio output control unit 263 then outputs the warning message audibly from the speaker 28. Here, the noise warning condition is, for example, when the cumulative noise level over a continuous period of time (e.g., 3 seconds) exceeds a warning threshold (e.g., 85 dB) or when the peak noise level exceeds a predetermined threshold.

[0082] Furthermore, when the warning processing unit 424 issues the above warning, it can notify the administrator's terminal (for example, the administrator terminal 8) of this by email or the like. This allows the administrator to call the user's mobile terminal 7 or a fixed telephone located in the shared space S and promptly and directly request the user to keep quiet.

[0083] Additionally, the warning processor 424 may generate an audio output command to issue an audio warning from the speaker 28 when the detected CO level exceeds the CO threshold or when the detected pollution level exceeds the pollution threshold. The warning message may simply convey the increase in the detected level or may prompt ventilation using the exhaust fan 6.

[0084] The voice guidance processing unit 425 generates a voice guidance output command based on each time generated by the reservation management unit 420. The generated voice output command is sent from the communication unit 41 to the shared space terminal 2 (wireless communication unit 241). As a result, the voice output control unit 263 of the shared space terminal 2 outputs the above warning message as voice from the speaker 28.

[0085] Specifically, the voice guidance processing unit 425 generates a voice output command for outputting a message indicating the arrival of the reservation start time (for example, "The start time has come. Please scan the QR code.") at the reservation start time ts. The voice guidance processing unit 425 also generates a corresponding voice output command for outputting a voice end notice message (for example, "The reservation will end in 10 minutes") from the speaker 28 at the end notice time t1. The voice guidance processing unit 425 also generates a voice output command for outputting a voice end message indicating the imminent end time of the reservation (for example, "The reservation will end soon. Please leave the room promptly.") at the exit guidance time t2. The voice guidance processing unit 425 also generates a voice output command for outputting a voice end message of the reservation (for example, "The reservation will end soon. Please leave the room promptly.") at the end guidance time t3.

[0086] The data processing unit 426, together with the database 43, provides graphical or numerical displays of various data to the input / output I / F 84 of the administrator terminal 8 based on the presence or absence of a signal received from the shared space terminal 2 or the detection level indicated by that signal. The graphical or numerical displays include real-time monitoring results for selected items and statistics of past monitoring results. The selected items include one or more of noise (detection results of the noise sensor 231), motion detection (detection results of the human presence sensor 23b), temperature (detection results of the temperature and humidity sensor 232), humidity (detection results of the temperature and humidity sensor 232), CO2 concentration (detection results of the CO2 sensor 233), and air pollution level (detection results of the IAQ sensor 234). These graphical or numerical displays may also be combined with the reception history of each operation signal from the shared space terminal 2 and the transmission history of each command from the cloud server 4 to the shared space terminal 2.

[0087] The lighting device 5 is typically an LED lighting device, a fluorescent lighting device, or the like. Since the lighting device 5 is flashed in this embodiment, this embodiment is particularly suitable for LED lighting devices that are highly resistant to flashing. The lighting device 5 includes a lighting circuit and a light source (both not shown). One input end of the lighting circuit is connected to an AC power source AC via a switch circuit 25, and the other input end is directly connected to the AC power source AC (see FIGS. 4 and 5 ). The lighting circuit is a general lighting ballast that converts an input AC voltage from the AC power source AC into a predetermined output current and supplies the output current to the light source. For example, if the light source is an LED, the lighting circuit is an electronic ballast equipped with a rectifier circuit and a DC / DC converter. Also, if the light source is a discharge lamp, the lighting circuit is an electronic ballast equipped with a rectifier circuit and a DC / AC converter or a magnetic ballast equipped with a copper-iron coil. The lighting circuit and the light source may be integrated to form a bulb-type lighting device.

[0088] The exhaust fan 6 is generally a ventilation device that exchanges indoor air with outdoor air. The exhaust fan 6 includes a drive circuit and a motor (both not shown). One input terminal of the drive circuit is connected to an AC power source AC via a switch circuit 25, and the other input terminal is connected directly to the AC power source AC (see FIGS. 4 and 5). The drive circuit is a typical motor drive circuit that converts an input AC voltage from the AC power source AC into a predetermined AC current or DC current and supplies the output current to the fan motor (i.e., the fan rotates).

[0089] In addition to the lighting device 5 and the ventilation fan 6, other devices (especially existing devices) can be connected by providing an extension connection terminal block (and extension terminals included therein) in addition to the connection terminal block 25b (see FIG. 6). Examples of other devices include a monitor (a display that displays the presence / absence of people in the shared space S, reservation information, etc.) installed outside the shared space S (for example, on the exterior wall), and an electronic lock installed on the door of the shared space S. In this case, too, the power supply wiring for the other devices is connected or disconnected in response to a corresponding switch command from the cloud server 4 (processing unit 42). For example, during usage hours, a display-on command is generated as a switch command, and the monitor is powered and in a display state. On the other hand, outside usage hours, a display-off command is generated as a switch command, and the monitor is shut down without being powered. Also, during usage hours, a lock command is generated as a switch command, and the electronic lock is powered and in a locked state (or can be locked / unlocked). On the other hand, outside usage hours, an unlock command is generated as a switch command, and the electronic lock is unlocked without being powered.

[0090] The mobile terminal 7 is a general information communication device such as a smartphone or tablet. The mobile terminal 7 includes a communication unit 71, a CPU 72, a memory 73, a display screen 74, and a camera 75. The communication unit 71 is a general communication means capable of communicating with the wireless LAN router 3 and the cloud server 4 (communication network N and communication unit 41). The CPU 72 and memory 73 are a processor and memory constituting a general computer, and it is assumed that necessary application programs have already been installed in the memory 73 and that the CPU 72 is capable of executing those programs. The display screen 74 is an input / output interface consisting of a touch panel as described above.

[0091] The administrator terminal 8 is, for example, a smartphone, a tablet, or a personal computer (PC). The administrator terminal 8 includes a communication unit 81, a CPU 82, a memory 83, and an input / output interface (I / F) 84. The communication unit 81 is a general communication means capable of communicating with the wireless LAN router 3 and the cloud server 4 via the communication network N. The CPU 82 and the memory 83 are a processor and memory constituting a general computer, and it is assumed that necessary application programs have already been installed in the memory 83 and that the CPU 82 is capable of executing those programs. The input / output I / F 84 is a touch panel if the administrator terminal 8 is a smartphone or a tablet, and is a display device (monitor) and input devices (keyboard, mouse, microphone, etc.) if the administrator terminal 8 is a PC.

[0092] The administrator can access the cloud server 4 from the administrator terminal 8 and set or change various settings on the cloud server 4. For example, the reservation management unit 420 can set or change the difference in time between the light-on time t0 and the reservation start time ts, as well as the difference in time between the reservation end time t1, the exit guidance time t2, the end announcement time t3, and the light-off time t4 and the reservation end time te. The display processing unit 421 can set or change the display content of the console screen 21 (selection of which of the objects 21a to 21k to display). The lighting command unit 422 can set or change whether a temporary light-off command (flashing of the lighting devices 5) is required at the reservation start time ts or the exit guidance time t2. The lighting command unit 422 can also manually generate a light-on command or a light-off command. The ventilation command unit 423 can set or change the correction values ​​for the CO2 threshold and detection level, whether a pollution detection warning (generation of an audio warning output command based on the detected pollution level) is required, and the pollution threshold. The ventilation command unit 423 can also set or change whether periodic ventilation (periodic operation of the ventilation fan 6) is required, whether automatic ventilation based on a human detection signal (operation of the ventilation fan 6 based on CO2 detection) is required, etc. The ventilation command unit 423 can also manually generate an operation command or a stop command.

[0093] The warning processing unit 424 can also set or change whether a noise warning (generation of a warning audio output command based on the detected noise level) is required, whether a notification that a noise warning has been issued is required to the manager, and the noise warning conditions and detection level correction value. Furthermore, the manager may be able to set or change the content of the warning message in the warning processing unit 424 via the input / output interface 84. Alternatively, the manager may be able to set or change the warning message via the input / output interface 84 substantially in real time, that is, by text input from a keyboard or voice input from a microphone and voice recognition processing. Furthermore, an appropriate functional section of the processing unit 42 can set or change whether an email notification is required when an indoor abnormality is detected based on a specific detection level and when an entry into the room outside of operating hours is detected.

[0094] Next, we will explain the timeline operation of the system 1. Figure 8 shows an example of the operation timeline of the system 1. In the reservation information in this example, the reservation start time is 14:00 and the reservation end time is 15:00. Furthermore, this shared space S has no reservations for the time period after 15:00 until 18:30, and extended use is possible.

[0095] In this example, the lighting time t0 is 13:55, five minutes before the reservation start time ts. At lighting time t0, the switch control unit 262 turns on switch SW5 of the switch circuit 25 in accordance with the lighting command to turn on the lighting device 5. At this point, the console control unit 261 displays a preparation screen including logos related to the system 1, the shared space terminal 2, or the shared space S on the console screen 21. If it is before the end time of the previous reservation at this point, the lighting device 5 is already turned on, so no lighting command is generated. Furthermore, the console screen 21 continues to display the screen related to the previous reservation.

[0096] At the reservation start time ts, the switch control unit 262 temporarily turns off the switch SW5 of the switch circuit 25 in accordance with the temporary light-off command, causing the lighting device 5 to blink. At the reservation start time ts, the console control unit 261 displays a screen 2101 shown in FIG. 9A on the console screen 21 in accordance with the console command. On this screen 2101, the current time display 21a indicates "14:00," the extended use guide display 21c indicates "18:30," and the remaining time display 21d indicates "01:00" (or "00:60" or "00:59"). The noise level display 21e, temperature display 21g, and humidity display 21h indicate "62 dB," "24°C," and "50%, respectively. The lighting soft switch 21i indicates an on state, and the ventilation soft switch 21j indicates a off state. At the reservation start time ts, the audio output control unit 263 outputs an audio message such as "The start time has come. Please scan the QR code" from the speaker 28 in accordance with the guidance audio output command.

[0097] When the user scans (captures) the image code display 21k on the screen 2101 using the camera 75 of the mobile terminal 7, the CPU 72 of the mobile terminal 7 accesses a website provided by the cloud server 4. In response to a mobile terminal console command generated by the display processing unit 421, a screen 7401 shown in Fig. 9B is displayed on the display screen 74. The group of objects displayed on the screen 7401 includes the group of objects on the screen 2101 excluding the image code display 21k.

[0098] Thereafter, while the shared space is in use (until the end notification time t3 or reservation end time te, described below), the console screen 21 of the shared space terminal 2 and the display screen 74 of the mobile terminal 7 maintain the form of screen 2101 and screen 7401, respectively, and the values ​​in the current time display 21a and remaining time display 21d change over time. Also, changes that occur in the noise level display 21e, temperature display 21g, humidity display 21h, lighting soft switch 21i, or ventilation soft switch 21j are synchronized between screen 2101 and screen 7401.

[0099] At the extension notification time ta, the console control unit 261, in accordance with a console command, causes the console screen 21 to display a screen 2102 shown in Fig. 9C. The screen 2102 displays a remaining time display 21d ("00:15"), an extension use notification display 21c ("18:30"), and an enlarged image code (QR code) 21k', and together with the QR code 21k', a message urging the user to extend the time, such as "If you wish to extend the time, please scan the QR code with your mobile phone," is displayed. This message may be output as audio from the speaker 28.

[0100] In this example, it is assumed that the user did not scan (capture) the QR code 21k' on the screen 2102. In other words, an extended use reservation is not made, and the original reservation end time te is applied.

[0101] In this example, the predicted end time t1 is 10 minutes before the reservation end time te, that is, 14:50. At the predicted end time t1, the voice output control unit 263 outputs a voice message such as "It will end in 10 minutes" from the speaker 28 in accordance with the voice guidance output command.

[0102] In this example, the exit guidance time t2 is 14:55, five minutes before the reservation end time te. At the exit guidance time t2, the switch control unit 262 temporarily turns off the switch SW5 of the switch circuit 25 in accordance with the temporary light-off command, causing the lighting device 5 to blink. If the lighting device 5 is in the off state, the switch control unit 262 temporarily turns on the switch SW5 of the switch circuit 25 in accordance with the temporary light-on command, causing the lighting device 5 to blink. The audio output control unit 263 outputs a voice message such as "The event will soon end. Please leave the room promptly" from the speaker 28 in accordance with the voice guidance output command.

[0103] In this example, the end announcement time t3 is 14:59, one minute before the reservation end time te. At the end announcement time t3, the audio output control unit 263 outputs a voice message such as "Thank you for using our service. The lights will be turned off in five minutes" from the speaker 28 in accordance with the audio announcement output command. If the lighting devices 5 have already been turned off by the user's switch operation, the voice message will simply be "Thank you for using our service." At the end announcement time t3 or the reservation end time te, the console control unit 261 displays the screen 2103 shown in FIG. 9D on the console screen 21 in accordance with the console command. The screen 2103 displays the logo, the current time display 21a, the noise level display 21e, the temperature display 21g, the humidity display 21h, and the lighting soft switch 21i or the ventilation soft switch 21j. The display screen 74 of the mobile terminal 7 displays, for example, the current time, the logo, and a message such as "Thank you for using our service. We look forward to seeing you again." At this point, the console screen 21 and the display screen 74 are no longer synchronized.

[0104] In this example, the turn-off time t4 is 15:05, which is five minutes after the reservation end time te. At the turn-off time t4, the switch control unit 262 turns off the switch SW5 of the switch circuit 25 in accordance with the turn-off command to turn off the lighting device 5.

[0105] If the user scans the QR code 21k' on the screen 2102 within the reserved time (for example, after the extension announcement time ta) (and completes payment for the extension reservation on a separate screen displayed on the mobile terminal 7), the extended use reservation is confirmed. Accordingly, new times t1 to t4 are reset based on the new extended reservation end time te. Therefore, the same operations as above are executed based on the new times t1 to t4 and the original time ta. However, the extension announcement time ta may change depending on the reservation status of other users thereafter.

[0106] If another reservation is made immediately after the reservation end time te, the extended use guide display 21c on the console screen 21 (screen 2101) and the extended use guide display 74c on the display screen 74 (screen 7401) will show "Not allowed." Also, the extended use guide time ta will not be adopted, and the screen 2102 will not be displayed. In this case, the light will not be turned off at time t4, and the audio output at time t3 will not mention turning off the light.

[0107] <Summary of the First Embodiment> As described above, the shared space terminal 2 of this embodiment is equipped with a wireless communication unit 24 (242) that receives, from the lighting command unit 422 of the cloud server 4, a light-on command generated at time t0 immediately before the reservation start time ts for the shared space S and a light-off command generated at time t4 immediately after the reservation end time te for the shared space S, a switch circuit 25 for connecting or disconnecting the power supply wiring of the lighting equipment 5 installed in the shared space S, and a switch control unit 262 that controls the switch circuit 25 to connect the power supply wiring in response to receiving a light-on command and controls the switch circuit 25 to disconnect the power supply wiring in response to receiving a light-off command.

[0108] In this way, when reserving use of the shared space S, the shared space terminal 2 connects the power supply wiring to turn on the lighting devices 5 just before the reservation start time ts, and disconnects the power supply wiring to turn off the lighting devices 5 just after the reservation end time te. As a result, the lights in the shared space S are effectively turned off outside of the reserved time, preventing users from continuing to use the space fraudulently. Therefore, according to this embodiment, a shared space terminal 2 and system 1 are realized that have high manageability that reliably prevents fraudulent use of the shared space outside of these hours, and are highly easy to implement because they do not require additional function settings for existing devices.

[0109] <Second embodiment> In the above first embodiment, a configuration was shown in which the light-on command and the light-off command were generated in the cloud server 4 and sent to the shared space terminal 2, but in the second embodiment, a configuration was shown in which the light-on command and the light-off command were generated in the shared space terminal 2.

[0110] Figure 10 shows a block diagram of a shared space management system 1 according to this embodiment. Note that in this embodiment, components similar to those in the first embodiment (see Figure 1) are given the same reference numerals, and their description will be omitted or simplified. In the system 1 of the first embodiment, the lighting command unit 422 was located on the cloud server, whereas in the system 1 of this embodiment, some of the functions of the lighting command unit 422 are located in the control unit 26 of the shared space terminal 2 as a lighting command unit 264. The reservation management unit 420 transmits the reservation start time ts, reservation end time te, turn-on time t0, exit guidance time t2, and turn-off time t4 obtained from the reservation information from the communication unit 41 to the wireless communication unit 242 of the shared space terminal 2.

[0111] The control unit 26 includes a console control unit 261, a switch control unit 262, an audio output control unit 263, and a lighting command unit 264. The lighting command unit 264 stores in the memory 27 the reservation start time ts, the reservation end time te, the turn-on time t0, the exit guidance time t2, and the turn-off time t4 received from the cloud server 4 via the wireless communication unit 242. The lighting command unit 264 generates a turn-on command at the turn-on time t0, a temporarily short-time turn-off command at the reservation start time ts, a temporarily short-time turn-off command or a turn-on command at the exit guidance time t2, and a turn-off command at the turn-off time t4. The switch control unit 262 opens and closes the switch SW5 of the switch circuit 25 based on the turn-on command or the turn-off command generated by the lighting command unit 264. As a result, the switch control unit 262 turns on the switch SW5 at the lighting time t0, temporarily turns off the switch SW5 at the reservation start time ts, temporarily turns off or on the switch SW5 at the exit guidance time t2, and turns off the switch SW at the lighting-out time t4. Therefore, the operation timeline in this embodiment is the same as that shown in FIG.

[0112] Note that the generation of a light-on command and a light-off command in response to the switch operation signal is performed by the lighting command unit 422, as in the system 1 of the first embodiment. However, the switch operation signal may be transferred from the cloud server 4 to the lighting command unit 264, and the light-on command or the light-off command may be generated from the switch operation signal in the lighting command unit 264. In either case, if the lighting device 5 is in a light-on state during the reserved time period, a light-off command is generated in response to the switch operation signal, and if the lighting device 5 is in a light-off state, a light-on command is generated in response to the switch operation signal (i.e., the light-on and light-off states are reversed).

[0113] <Summary of the Second Embodiment> As described above, the shared space terminal 2 of this embodiment is equipped with a wireless communication unit 24 (242) that receives reservation information including the reservation start time ts and reservation end time te for the shared space S from the cloud server 4, a lighting command unit 264 that generates a light-on command at time t0 immediately before the reservation start time ts and generates an off command at time t4 immediately after the reservation end time te, a switch circuit 25 for connecting or disconnecting the power supply wiring of the lighting devices 5 in the shared space S, and a switch control unit 262 that controls the switch circuit 25 to connect the power supply wiring in response to the generation of a light-on command and controls the switch circuit 25 to disconnect the power supply wiring in response to the generation of a light-off command.

[0114] Thus, in this embodiment, the shared space terminal 2 also connects the power supply wiring to turn on the lighting devices 5 just before the reservation start time ts, and disconnects the power supply wiring to turn off the lighting devices 5 just after the reservation end time te. As a result, the lights in the shared space S are effectively turned off outside of the reservation time, preventing users from continuing to use the shared space fraudulently. Therefore, this embodiment also realizes a shared space terminal 2 and system 1 that have high manageability to reliably prevent fraudulent use of the shared space outside of these hours, and are highly easy to implement because they do not require additional function settings for existing devices. Furthermore, because sequential wireless communication is not required for the lighting device 5 to be turned on and off, the effects of the above-mentioned on / off operation can be reliably obtained even if a communication failure occurs while the shared space S is being used.

[0115] <Summary of Common Features Between the First and Second Embodiments> It is preferable that the differential time Te-4 from the reservation end time te to the lights-out time t4 be 30 minutes or less. If the differential time Te-4 is 0 minutes, high manageability can be achieved by disabling use after the reservation time. On the other hand, if the differential time Te-4 is more than 0 minutes and less than 30 minutes, a certain level of manageability can be ensured while providing a certain amount of grace period for use after the reservation time, making the shared space S user-friendly. In addition, taking into consideration both manageability and user-friendliness, it is particularly preferable that the above differential time be 5 minutes or less.

[0116] It is preferable that the difference time T0-s from the lighting time t0 to the reservation start time ts be 30 minutes or less. If the difference time T0-s is 0 minutes, use before the reservation time is not permitted, thereby achieving high manageability. On the other hand, if the difference time T0-s is more than 0 minutes and less than 30 minutes, use before the reservation time, such as users entering and gathering, is permitted, thereby reducing the number of users waiting outside the shared space S and eliminating causes such as noise to the surrounding area and obstructions to traffic. This makes it possible to achieve smooth operation of the shared space S while ensuring manageability. In consideration of achieving both manageability and smooth operation, it is preferable that the above difference time be 10 minutes or less.

[0117] The lighting command unit 422 or 264 is configured to generate a turn-off command or a turn-on command to temporarily reverse the on / off state of the lighting devices 5 at a predetermined exit guidance time t2 before the reservation end time te. This causes the lighting devices 5 to blink, visually and intuitively informing the user that the reservation end time is approaching and urging the user to prepare to leave the room as the reservation time ends.

[0118] The lighting command unit 422 or 264 is configured to generate a command to temporarily turn off the lights at the reservation start time ts. This allows the lighting devices 5 to blink to visually and intuitively notify the user of the reservation start time.

[0119] The shared space terminal 2 further includes a switch button that outputs a switch operation signal in response to a press or touch operation by a user of the shared space S. The lighting command unit 422 or 264 is configured to generate a turn-off command in response to the switch operation signal if the lighting device 5 is on during the period after the reservation start time ts or time t0 and before the reservation end time te or time t4, and to generate a turn-on command in response to the switch operation signal if the lighting device 5 is off. This allows manual operation by the user to be accepted during the usage time, increasing the convenience of the shared space S.

[0120] The lighting command unit 422 or 264 is configured to generate a lighting command only for the provisional lighting period in response to a switch operation signal during the period before lighting time t0 or the period after lighting time t4. This allows the shared space S to be used temporarily outside of opening hours for purposes such as patrols by the manager (staff) of the shared space S or for users to retrieve forgotten items, thereby increasing the convenience and safety of the shared space S. In addition, given the purpose of temporary use outside of opening hours, it is preferable that the provisional lighting period be between 5 seconds and 1 minute.

[0121] The lighting command unit 422 or 264 is configured to generate a lighting command for a predetermined forced lighting period in response to a specific operation signal generated in response to a specific operation on the console screen 21 during the period before lighting time t0 or the period after lighting time t4. This allows cleaning staff, maintenance staff, and other workers to work outside of working hours in the shared space S, and enables the manager to manage the working hours of these workers.

[0122] The shared space terminal 2 further includes an environmental sensor 23a that detects predetermined environmental components within the shared space S and outputs the environmental level, and a wireless communication unit 243 that transmits the environmental level to the cloud server 4. The cloud server 4 includes a ventilation command unit 423 that generates an operation command when the environmental level exceeds a predetermined threshold. The switch circuit 25 is configured to connect or disconnect the power supply wiring of the ventilation fan 6 installed in the shared space S, and the switch control unit 262 controls the switch circuit 25 to connect the power supply wiring in response to the operation command received from the ventilation command unit 423 via the wireless communication unit 242. As a result, the ventilation fan 6 is operated in response to a deterioration in the environmental level, and the comfort of the shared space S is maintained.

[0123] The environmental component is, for example, carbon dioxide. This prevents the deterioration of the sanitary environment of the shared space S due to overcrowding of users. The environmental component is, for example, carbon monoxide, nitrogen dioxide, or volatile organic compounds. This prevents the deterioration of the sanitary environment of the shared space S due to factors other than the users' bodies (for example, cigarette smoke).

[0124] <Modification> Although the preferred embodiment of the present invention has been described above, the present invention can be modified in various ways, for example, as shown below.

[0125] (1) Variations regarding Shared Space S In the above embodiments, the shared space S is a rental conference room, but the shared space terminal 2 and the shared space operation system 1 can be applied to any space that requires lighting and can be rented by the hour. For example, the shared space S may be a shared gym, a shared booth, a shared office, a shared studio, a rental study room, a rental eating and drinking space, etc.

[0126] (2) Variations in communication standards In the above embodiments, the wireless communication unit 24 (241-243) and the wireless LAN router 3 perform Wi-Fi communication. However, other communication standards, whether currently available or developed in the future, may be adopted as long as they can achieve similar wireless communication functions. For example, while the present embodiment employs 2.4 GHz band Wi-Fi communication, 5 GHz band Wi-Fi communication may also be adopted. Furthermore, a mobile SIM may be used for the wireless communication unit 24. In this case, the shared space terminal 2 and the communication network N (cloud server 4) are directly connected via wireless communication, eliminating the need for the wireless LAN router 3. Furthermore, even if the mobile terminal 7 is located within the shared space S, it may communicate directly with the communication network N without going through the wireless LAN router 3.

[0127] (3) Modification of the operation mode of the lighting device 5 after the lights-out time In the above embodiments, the lighting devices 5 are turned off at the lights-out time t4 and maintained in the off state after the lights-out time t4. Alternatively, the lighting devices 5 may be configured to blink after the lights-out time t4. This creates an environment that is even more inhospitable for unauthorized off-hours users. This blinking operation can be performed, for example, by the lighting command unit 422 repeatedly (e.g., at intervals of several seconds) sending a light-on command and a light-off command to the shared space terminal 2 in response to a presence signal from the human presence sensor 23b received by the cloud server 4 after the time t4.

[0128] (4) Modifications to console screen 21 In each of the above embodiments, the console screen 21 is configured as a touch panel, but it may be a display that only displays information instead of a touch panel. In this case, a desired operation is performed by operating an object (such as a lighting soft switch 74i or a ventilation soft switch 74j) displayed on the display screen 74 of the mobile terminal 7.

[0129] (5) Variation 1 regarding noise warnings In the above embodiments, a warning message is output as a sound as a noise warning when the detected noise level exceeds the warning threshold. However, the display on the console screen 21 may be changed. For example, as a noise warning, the warning processing unit 424 and the display processing unit 421 may enlarge and display the noise level display 21e (e.g., only the noise level display 21e) on the console screen 21. After the user scans the image code display 21k with the mobile terminal 7, the warning processing unit 424 and the display processing unit 421 may enlarge and display the noise level display 74e (e.g., only the noise level display 74e) on the display screen 74 as a noise warning. The warning processing unit 424 may also vibrate the mobile terminal 7. The warning processing unit 424 and the display processing unit 421 may flash the noise level display 21e or 74e before or after enlargement. This further enhances the user's awareness of the increase in noise level.

[0130] (6) Variation 2 regarding noise warnings In the above embodiments, a warning message is output as a voice message as a noise warning when the detected noise level exceeds the warning threshold. On the other hand, if the number of warning messages issued before the extension notice time ta exceeds a predetermined number, the system may be configured not to issue an extended use notice even if the extended use is possible. For example, in the above case, the warning processing unit 424 and the display processing unit 421 may display the extended use notice display 21c on the console screen 21 as "not permitted" regardless of whether the extended use is possible, or may not display the extended use notice display 21c at all. Accordingly, the display processing unit 421 may not display the screen that was supposed to be displayed at the extension notice time ta (screen 2102 in FIG. 9C ). Furthermore, even after the image code 21k is scanned by the mobile terminal 7, the extended use notice display 74c on the display screen 74 may be displayed as "not permitted," or may not display the extended use notice display 74c at all. This prevents users who may cause noise problems from extending their use, ensuring comfortable use by users of other nearby shared spaces S.

[0131] (6) Variation 3 regarding noise warnings In the above embodiments, the warning necessity and warning threshold are set to variable fixed values. However, the warning necessity and warning threshold may be variable depending on the usage status of other nearby shared spaces S. For example, if a nearby (e.g., adjacent) shared space S2 of the reserved target shared space S1 is vacant, the warning processing unit 424 may negate the warning necessity for the target shared space S1 or raise the warning threshold. Therefore, even during a single usage time period of the target shared space S1, the warning necessity and warning threshold may be automatically changed depending on the usage status of the nearby shared space S2. Whether the nearby shared space S2 is vacant can be determined from the reservation information obtained from the reservation management unit 420 or the detection results of the human presence sensor 23b. This allows for noise from users of the target shared space S1 to be tolerated to the extent that no actual harm occurs, promoting lively discussions and smooth communication.
