Summary of the Invention

Problems to be Solved by the Invention

[0004] However, according to the configuration of Patent Document 1, an unspecified number of users will perform touch operations on the same information processing terminal, which is not hygienically favorable from the perspective of infectious disease prevention measures. According to the configuration of Patent Document 2, regarding a conference system shared by a large number of users, each user can perform operations via their own mobile terminal. However, for users, the relationship between the operation content displayed on the screen of their mobile terminal and the function of the conference system is not intuitive, and it is difficult to obtain a sense of mutual connection.

[0005] Therefore, an object of the present invention is to provide a shared space operation system and a shared space operation method that enable users of a shared space to utilize the functions of a shared space terminal in a non-contact manner and with a high sense of connection.

Means for Solving the Problems

[0006] A shared space operation system according to a first aspect of the present invention includes a shared space terminal disposed in a shared space and a cloud server connected to be wirelessly communicable with the shared space terminal. The shared space terminal includes a console screen, a console control unit that displays a first object group and an object of an image code on the console screen based on a first console command received from the cloud server, and a switch control unit that controls the load installed in the shared space based on a switch command received from the cloud server. The cloud server includes a display command unit that generates a first console command for displaying an image of the first object group and an object of an image code, and a second console command for synchronously displaying a second object group including a substantial part of the first object group on the display screen of a mobile terminal that has captured the object of the image code on the console screen, and a switch command unit that generates a switch command in response to a touch operation on a predetermined object included in the second object group. The shapes of the objects commonly included in the first object group and the second object group are substantially the same.

[0007] The shared space operation method according to the second aspect of the present invention is executed between a shared space terminal disposed in a shared space and a cloud server that is wirelessly communicably connected to the shared space terminal. The cloud server transmits a first console command for displaying an object of a first object group and an image code to the shared space terminal. The shared space terminal displays an object of the first object group and an object of the image code on a console screen based on the first console command. In response to the mobile terminal capturing an object of the image code, the cloud server transmits a second console command for synchronously displaying a second object group including a substantial part of the first object group on the first object group to the mobile terminal. In response to a touch operation on a predetermined object included in the second object group, the cloud server transmits a switch command to the shared space terminal. The shared space terminal controls a load installed in the shared space based on the switch command. The shapes of the objects commonly included in the first object group and the second object group are substantially the same.

[0008] According to the above first and second aspects, on the display screen of the mobile terminal that has captured the object of the image code, a second object group that substantially includes a substantial part of the first object group of the console screen in substantially the same shape is synchronously displayed. Then, a switch command is generated in response to a touch operation on a predetermined object included in the second object group, and accordingly, the load installed in the shared space is controlled. Thereby, a shared space operation system is realized that enables a user of the shared space to use the functions of the shared space terminal in a non-contact manner and with a high sense of linkage. In the present disclosure, the substantial part of the first object group is defined as more than half of the objects included in the first object group, or the objects included in more than half of the exclusive area of the first object group. Also, the shapes being substantially the same includes not only the case where the two shapes are completely the same, but also the case where the two shapes are similar with a slight difference in the visual perception of the general user.

[0009] In the above first and second aspects, the load is a lighting device installed in the shared space, each of the first and second object groups includes a lighting soft switch related to the lighting or extinguishing of the lighting device, and the switch command unit is configured to generate a switch command for lighting or extinguishing the lighting device in response to a touch operation on the lighting soft switch included in the second object group. Since the lighting device is an essential load in the shared space, a highly versatile shared space operation system that is useful for any shared space is realized.

[0010] In the above-described first and second aspects, the load is a ventilation fan installed in the shared space, each of the first and second object groups includes a ventilation soft switch related to the operation or stop of the ventilation fan, and the switch command unit is configured to generate a switch command for operating or stopping the ventilation fan in response to a touch operation on the ventilation soft switch included in the second object group. Since ventilation is essential in a shared space used by an unspecified number of users, a highly versatile shared space operation system useful for any shared space is realized.

[0011] In the above-described first and second aspects, the display command unit is configured to generate first and second console commands for reversely displaying the object of the switch button included in the first and second object groups in response to a touch operation on the object of the switch button included in the second object group. Thereby, the display of the first and second object groups that have been operated is reversed simultaneously, enhancing the sense of link from the mobile terminal to the shared space terminal.

[0012] In the above-described first and second aspects, each of the first and second object groups preferably includes (a) an object for displaying the current time, (b) an object for displaying the reservation end time of the shared space, (c) an object for indicating whether extension use of the shared space is possible or, if extension use is possible, the final possible use time, and (d) an object for displaying the remaining time corresponding to the value obtained by subtracting the current time from the reservation end time. Thereby, comprehensive information regarding the reservation of the shared space is displayed, enhancing the listability of information regarding the reservation.

[0013] In the above-described first and second aspects, each of the first and second object groups preferably includes (a) an object for displaying the current time, (c) an object for indicating whether extension use of the shared space is possible or, if extension use is possible, the final possible use time, and (d) an object for displaying the remaining time corresponding to the value obtained by subtracting the current time from the reservation end time. Thereby, the minimum necessary information regarding the reservation of the shared space is displayed, and in particular, the space on the display screen of the mobile terminal can be effectively utilized.

[0014] In the above first aspect, the display command unit is configured to generate a second console command for causing a screen for extension use reservation to be displayed on the display screen of the mobile terminal in response to a touch operation on the object (c) included in the second object group. In the above second aspect, the method further includes a step in which the cloud server transmits a second console command for causing a screen for extension use reservation to be displayed on the display screen of the mobile terminal in response to a touch operation on the object (c) included in the second object group. Thereby, the promotion of the extended use of the shared space and the utilization rate thereof can be improved.

[0015] In the above first and second aspects, it is preferable that the positional relationship between the first and second objects included in the first object group is the same as the positional relationship between the third and fourth objects included in the second object group and corresponding to the first and second objects. In this way, by the positional relationship of specific objects being the same between the first object group and the second object group, erroneous operations due to misrecognition between specific objects can be prevented.

[0016] In the above first and second aspects, it is preferable that the positional relationship of all the objects included in the first object group is the same as the positional relationship of all the objects included in the second object group. Thereby, the sense of link from the mobile terminal to the shared space terminal is further enhanced.

[0017] In the above first and second aspects, the second object group is displayed on the display screen only during the period from the reservation start time to the reservation end time of the shared space. Thereby, the manageability regarding the reserved use of the shared space is ensured.

MODE FOR CARRYING OUT THE INVENTION

[0019] <Embodiment> FIG. 1 shows a block diagram of a shared space operation system 1 (hereinafter referred to as "system 1") according to an embodiment of the present invention. The system 1 includes a shared space terminal 2 disposed in a shared space S and a cloud server 4 (cloud service) wirelessly communicably connected to the shared space terminal 2 via a wireless LAN router 3. In the present embodiment, the shared space S is a rental conference room, and lighting equipment 5 and a ventilation fan 6 (loads) are installed in the shared space S. The system 1 can cooperate with a mobile terminal 7 of a user 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. Further, the system 1 can cooperate with an appropriate schedule management application A such as Google Calendar (registered trademark) via the communication network N. In FIG. 1, a pair of shared spaces S and shared space terminals 2 are shown, but the system 1 may include a plurality of pairs of shared spaces S and shared space terminals 2.

[0020] Generally, in the system 1, a mobile terminal 7 of a user who has scanned an image code displayed on the screen of the shared space terminal 2 is provided with a screen display similar to that of the shared space terminal 2. That is, a so-called transfer display from the shared space terminal 2 to the mobile terminal 7 is performed. Thereby, the user can use the same functions as the shared space terminal 2 through browsing or operation on the screen of the mobile terminal 7.

[0021] 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 has a triangular prism shape with a substantially vertical triangle cross section perpendicular to the longitudinal direction. The housing 20 has a bottom surface 20a, a rear surface 20b perpendicular to the bottom surface 20a, and a front surface 20c connecting the bottom surface 20a and the rear surface 20b. The connecting portions of the bottom surface 20a, the rear surface 20b, and the front surface 20c are continuous with rounded edges. Both side surfaces 20d and 20e, which are the horizontal ends of the housing 20, form a substantially 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, preferably 9.3 cm ± 0.5 cm. However, the external dimensions of the housing 20 are not limited to the above. Note that the shared space terminal 2 can be a wall-mounted type, a placement type, etc., so a wall mounting structure may be provided on the rear surface 20b, or legs (protrusions at the four corners, non-slip rubber at the four corners, etc.) may be provided on the bottom surface 20a.

[0022] FIG. 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 section 22, and a sensor section 23. In the present embodiment, on the front surface 20c, the console screen 21, the physical switch section 22, and the sensor section 23 are arranged from left to right, but these arrangements or placements are not limited to those shown in the figure.

[0023] The console screen 21 is an LCD display, an OLED display, etc., which displays necessary information according to the situation and accepts the touch operations of the user. The console screen 21 displays the current time display 21a, the reservation end time display 21b, the extension usage guidance display 21c, and the remaining time display 21d (hereinafter, these are also referred to as objects 21a to 21d) regarding the reservation information of the shared space S. In addition, 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 regarding the environmental information of the shared space S (hereinafter, these are also referred to as objects 21e to 21h). Further, the console screen 21 iconically displays a lighting soft switch 21i and a ventilation soft switch 21j regarding the operation information of the lighting device 5 and the ventilation fan 6 (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").

[0024] The maximum available time for the extension usage of the shared space S where the shared space terminal 2 is arranged is displayed on the extension usage guidance display 21c. This maximum available time is assumed to be the time within the day. When the extension usage of the shared space S is not possible, "not available" is displayed on the extension usage guidance display 21c.

[0025] The value of the remaining time display 21d is the value obtained by subtracting the value of the current time display 21a from the value of the reservation end time display 21b. When this remaining time becomes 60 minutes or less, it is displayed, and the remaining time (unit: minute) is displayed as a countdown. Also, as shown in the figure, the remaining time display 21d is displayed together with a predetermined circular graph. The circumference of this graph corresponds to 60 minutes. The moving end (the lower end of the thick line circumference) indicating the current value of the graph moves counterclockwise and ends at the uppermost position (the 0 o'clock position). Note that the moving end indicating the current value may move clockwise and end at the uppermost position (the 12 o'clock position). Also, when the remaining time becomes 1 minute or less, the circumference may be made to correspond to 60 seconds, and the remaining time (unit: second) may be displayed as a countdown.

[0026] The lighting soft switch 21i is displayed with black and white inversion depending on whether the lighting device 5 is in the lit state or the off state. For example, when the lighting device 5 is in the lit state, a black-based display is applied, and when the lighting device 5 is in the off state, a white-based display is applied. Similarly, the ventilation soft switch 21j is displayed with black and white inversion depending on whether the ventilation fan 6 is in the operating state or the stopped state. For example, when the ventilation fan 6 is in the operating state, a black-based display is applied, and when the ventilation fan 6 is in the stopped state, a white-based display is applied.

[0027] The image code displayed on the image code display 21k is preferably a two-dimensional code such as a QR code (registered trademark), DataMatrix (registered trademark), VeriCode (registered trademark), etc. In this embodiment, a QR code is adopted (hereinafter, also referred to as "QR code 21k"). However, this embodiment can also be implemented even if the image code is a one-dimensional code such as a barcode. Also, as shown in the figure, the QR code 21k may include a display for guiding the reading of the image code by the mobile terminal 7. Other objects will be described later.

[0028] The physical switch section 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 pressing operation by the user, and the ventilation physical switch 22b outputs a ventilation operation signal in response to a pressing operation by the user. These operation signals are transmitted to the cloud server 4. Note that the lighting physical switch 22a is provided with a display lamp 22c such as an LED indicating the current operating state (lit or off) of the lighting device 5, and the ventilation physical switch 22b is provided with a display lamp 22d such as an LED indicating the current operating state (operating or stopped) of the ventilation fan 6. The lighting / extinguishing of the display lamp 22c may correspond to the lighting / extinguishing of the lighting device 5, or may correspond to the extinguishing / lighting of the lighting device 5. The lighting / extinguishing of the display lamp 22d may correspond to the operation / stop of the ventilation fan 6, or may correspond to the stop / operation of the ventilation fan 6.

[0029] Note that, by definition, the lighting soft switch 21i, the lighting physical switch 22a, the ventilation soft switch 21j, and the ventilation physical switch 22b are collectively referred to as the switch button. Also, the touch operation on the lighting soft switch 21i, the pressing operation on the lighting physical switch 22a, the touch operation on the ventilation soft switch 21j, and the pressing operation on the ventilation physical switch 22b are collectively referred to as the switch operation, and the signals output by the switch operation are collectively referred to as the switch operation signal.

[0030] The sensor unit 23 includes an environment sensor 23a (strictly speaking, the air intake hole for the environment sensor 23a is shown in the figure) and a human presence sensor 23b. The environment sensor 23a detects and outputs the environmental level in the air acquired from the air intake hole. Details of the environment sensor 23a and the human presence sensor 23b will be described later.

[0031] Returning to FIG. 1, each part of the shared space terminal 2 will be described. 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 enables the exchange of necessary signals, data, or power.

[0032] The environment sensor 23a of the sensor unit 23 includes a noise sensor 231, a temperature and humidity sensor 232, a CO2 sensor 233, and an indoor air quality (IAQ) sensor 234. The various environmental levels within the shared space S are specified by the environment sensor 23a. Note that an atmospheric pressure sensor for detecting atmospheric pressure may be employed as the environment sensor. The 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.

[0033] The noise sensor 231 detects sound pressure and outputs a noise level (decibel) converted from the sound pressure (hereinafter referred to as "detected noise level"). The noise sensor 231 may be configured to detect sound pressure in a predetermined frequency range such as the frequency range of human voices (for example, about 100 to 2000 Hz). A detection signal indicating the detected noise level is transmitted from the wireless communication unit 243 to the cloud server 4 via the wireless LAN router 3.

[0034] The temperature and humidity sensor 232 detects temperature and humidity and outputs a temperature value and a humidity value (hereinafter referred to as "detected temperature", "detected humidity", or "detected temperature and humidity"). Note that the temperature and humidity sensor 232 may be a temperature sensor that detects only temperature and outputs a temperature value, or a humidity sensor that detects only humidity and outputs a humidity value. A detection signal indicating the detected temperature and the detected humidity is transmitted from the wireless communication unit 243 to the cloud server 4 via the wireless LAN router 3.

[0035] The CO2 sensor 233 detects carbon dioxide (CO2) by the NDIR (Non Dispersive InfraRed) method and outputs a CO2 concentration (hereinafter referred to as "detected CO2 concentration"). Since an increase in the CO2 concentration can be attributed to human respiration, it can be an indicator of the degree of human crowding. 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.

[0036] The IAQ sensor 234 detects pollutants and outputs their concentration (hereinafter referred to as "detected pollution level"). The pollutants to be detected are carbon monoxide (CO), nitrogen dioxide (NO2), or volatile organic compounds (VOCs). The sources of pollutants are, in particular, tobacco smoke, or VOCs from formaldehyde, asbestos, dust, exhaust gas, 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.

[0037] The human presence sensor 23b of the sensor unit 23 is an infrared human presence sensor that detects the presence or absence of a human body in the shared space S (or its predetermined detection area). When the human presence sensor 23b detects the presence of a human body, it outputs a presence signal, and in other cases (i.e., when the human body is absent), it outputs an absence signal. Note that the presence signal / absence signal may be a high-level signal / low-level signal, respectively, or a low-level signal / high-level signal, or signal output present / absent, signal output absent / present, or a UART signal. In the present 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.

[0038] 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 to form one wireless communication unit or may be three separate wireless communication units (in this embodiment, the latter is adopted). Each of the wireless communication units 241 to 243 wirelessly communicates with the wireless LAN router 3 under the communication control of the control unit 26 or autonomously. Each of the wireless communication units 241 to 243 is a Wi-Fi unit for performing Wi-Fi (registered trademark) communication in this embodiment, for example, a Wi-Fi device operating at 2.4 GHz (802.11b / g / n).

[0039] 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 switch operation signals from the lighting soft switch 21i and the ventilation soft switch 21j. Also, the wireless communication unit 241 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. Also, the wireless communication unit 242 receives a switch command (lighting command, extinguishing command, operation command, and stop command), which will be described later, 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.

[0040] In this way, by providing separate Wi-Fi units for the console screen 21, the physical switch unit 22, and the sensor unit 23, it becomes possible to diagnose the wireless communication state. For example, in the cloud server 4, if a part of the screen operation signal, the physical switch operation signal, and the sensor detection signal is not received, it is presumed that the wireless LAN router 3 and the communication network N are normal, but there is a fault in the wireless communication unit corresponding to the non-received signal or the part to which it belongs. Also, in the cloud server 4, if all of the screen operation signal, the physical switch operation signal, and the sensor detection signal are not received, it is presumed that there is a fault in the wireless LAN router 3 or a communication failure in the communication network N.

[0041] The switch circuit 25 is connected between an AC power supply AC (for example, a commercial power supply) and the lighting device 5 and the ventilation fan 6. Under the control of the control unit 26 (switch control unit 262), the switch circuit 25 connects / disconnects the power supply wiring between the AC power supply AC and the lighting device 5, and connects / disconnects the power supply wiring between the AC power supply AC and the ventilation fan 6.

[0042] Fig. 4 shows a circuit diagram of a wiring example related to the switch circuit 25. The switch circuit 25 consists of a relay switch and has terminals 251 to 254 on the AC power supply AC side, a terminal 255 connected to the lighting device 5, and a terminal 256 connected to the ventilation fan 6. Note that terminals 251, 252, and 253 are interconnected. The path between terminal 252 and terminal 255 is opened and closed by switch SW5, and the path between terminal 251 and terminal 256 is opened and closed by switch SW6.

[0043] The non-grounded wiring L1 of the AC power supply AC is connected to the non-grounded (hot) side terminal of the plug receptacle 91 (so-called socket). The grounded wiring L2 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) side 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 non-grounded side terminal of the plug 92 via wiring L3, and terminal 254 is connected to the grounded side terminal of the plug 92 via wiring L4. Hereinafter, the description will be made assuming that the plug 92 is correctly connected to the plug receptacle 91.

[0044] The opening and closing of switch SW5 and the opening and closing of switch SW6 are individually controlled by the control unit 26 (switch control unit 262). When switch SW5 is on (closed), the lighting device 5 is powered through the power supply wiring (L1, L3, L5, and L2) from the AC power supply AC and lights up. On the other hand, when switch SW5 is off (open), the lighting device 5 is cut off from the AC power supply AC and goes out. Similarly, when switch SW6 is on (closed), the ventilation fan 6 is powered through the power supply wiring (L1, L3, L6, and L2) from the AC power supply AC and operates. On the other hand, when switch SW6 is off (open), the ventilation fan 6 is cut off from the AC power supply AC and stops.

[0045] Fig. 5 shows a circuit diagram of another wiring example for the switch circuit 25. Components having the same configuration as those in the circuit of Fig. 4 are denoted by the same reference numerals, and redundant descriptions are omitted. A single-phase conductor 94 is connected to the switch circuit 25. The non-grounded wiring L1 and the grounded wiring L2 are connected to the AC power supply AC via a single-phase breaker 93. The wiring L1 is connected to the terminal 251 of the switch circuit 25 and the terminal 941 of the single-phase conductor. The wiring L2 is connected to one terminal of the ventilation fan 6, the terminal 254 of the switch circuit 25, and the input terminal 942 and the control terminal 944 of the single-phase conductor 94. The other terminal of the ventilation fan 6 is connected to the terminal 256 via the wiring L6. The terminal 255 is connected to the control terminal 943 of the single-phase conductor 94 via the wiring L5. The output terminals 945 and 946 of the single-phase conductor 94 are connected to the lighting device 5 via the wirings L51 and 52. Hereinafter, the description will be made on the assumption that the single-phase breaker 93 is in the on (energized) state.

[0046] The opening / closing of the switch SW5 and the opening / closing of the switch SW6 are individually controlled by the control unit 26 (switch control unit 262). When the switch SW5 is on, in the single-phase conductor 94, the control terminals 943 and 944 are powered from the AC power supply AC, and the connection between the input terminal 941 and the output terminal 945 and the connection between the input terminal 942 and the output terminal 946 are established. As a result, the lighting device 5 is powered via the power supply wirings (L1, L51, L2, and L52) from the AC power supply AC and lights up. On the other hand, when the switch SW5 is off, the control terminal 943 of the single-phase conductor 94 is not powered, the connection between the input terminals 941 and 942 and the output terminals 945 and 946 is turned off, and the lighting device 5 is disconnected from the AC power supply AC and turns off. Also, similar to the case of Fig. 4, when the switch SW6 is on, the ventilation fan 6 is powered via the power supply wirings (L1, L6, and L2) from the AC power supply AC and operates. On the other hand, when the switch SW6 is off, the ventilation fan 6 is disconnected from the AC power supply AC and stops.

[0047] In this way, in the configuration of FIG. 5, since the load current to the lighting device 5 does not pass through the switch circuit 25, 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. Also, by appropriately selecting and expanding the conductor 94, it is possible to perform on / off control of the wiring of the power outlet, small to large air conditioners, etc. Note that the block diagram of FIG. 1 corresponds to the circuit configuration of FIG. 4, but those skilled in the art should be able to apply the circuit configuration of FIG. 5 to the block diagram of FIG. 1 instead of the circuit configuration of FIG. 4.

[0048] FIG. 6A shows a rear view (rear surface 20b) and a side view (side surface 20d) of the shared space terminal 2 (corresponding to the wiring of FIG. 4). FIG. 6B shows a side partial cross-sectional view when the rear surface 20b of the shared space terminal 2 is attached to the wall surface W. The rear surface 20b is provided with a recess 20g for wiring and a hole 20h for wall mounting. The recess 20g has a tapered shape, and the depth (horizontal recess depth) increases from the upper side to the lower side (toward the bottom surface 20a side). Therefore, the bottom surface 20a has a notch. As shown in FIG. 6B, the wall surface 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 surface W such that the recess 20g corresponds to the wall holes Wh. When the shared space terminal 2 is attached to the wall surface W in this way, the lower part of the recess 20g is open inside the bottom surface 20a, and the upper part of the recess 20g is blocked by the wall surface W and the rear surface 20b.

[0049] In the recessed portion 20g, connection terminal blocks 25a and 25b are arranged. The connection terminal block 25a has terminals 251 and 254 (not shown) on the AC power supply side, and the 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, the wirings L3 and L4 are inserted and connected to the connection terminal block 25a, and the wirings L5 and L6 are connected to the connection terminal block 25b. As shown in FIG. 6B, the wirings L3 and L4 extend downward outside the wall surface W from the connection terminal block 25a through the notch portion of the bottom surface 20a, and the wirings L5 and L6 extend into the wall surface W from the connection terminal block 25b through the wall hole Wh. Note that the wirings L3 and L4 may also be wired inside the wall surface W. In the case of the wiring shown in FIG. 5, the wirings L1 and L2 are inserted and connected to the connection terminal block 25a, and the wirings L5 and L6 are connected to the connection terminal block 25b. The wirings L1 and L2 in the case of FIG. 5 can be wired inside the wall surface W. Note that in the wiring shown in FIG. 4, when there are a plurality of lighting devices 5 in a system, the wirings L5 of each system are collectively connected to the terminal 255 (not shown) of the connection terminal block 25b. In the wiring shown in FIG. 5, when there are a plurality of lighting devices 5, since the wirings L51 and L52 of each system are connected to the output terminals 945 and 946 of the single-phase conductor 94, the wiring connected to the terminal 255 (not shown) of the connection terminal block 25b of the switch circuit 25 is only the wiring L5.

[0050] In the recessed portion 20g, a power connector 29 (insertion port) for supplying the operating power of the shared space terminal 2 is also provided. A DC power jack (not shown) of an AC / DC adapter is inserted into the power connector 29. Thereby, a DC voltage is supplied to the shared space terminal 2, and the operating power is supplied to each part through an appropriate constant voltage circuit (not shown) inside the housing 20. In the present embodiment, the shared space terminal 2 is configured to operate with a DC power supply. However, when an AC / DC converter is arranged inside the shared space terminal 2, an 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. The AC cable, the wirings L3 and L4 may be physically or electrically bundled and wired as one AC cable. Alternatively, a battery may be provided inside the housing 20, and the operating power of the shared space terminal 2 may be supplied from the battery. In this case, the power connector 29 is unnecessary.

[0051] Returning to FIG. 1, each part 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 a microcomputer and its peripheral circuits. In the present embodiment, one control unit 26 is shown, but 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 respective parts, the control unit 26 can appropriately execute various general functions (clock function, timing function, communication control function, arithmetic processing function, etc.). The memory 27 includes a ROM for storing programs and the like, and a RAM for temporarily storing data, programs, and the like. In FIG. 1, the memory 27 is included in the control unit 26, but the memory 27 may be outside the control unit 26.

[0052] The console control unit 261 causes the console screen 21 to display a screen 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 which of the objects 21a to 21k to display, the display content (numerical value, black-and-white inversion, etc.) of each displayed object, the arrangement of the selected object, and the like.

[0053] The switch control unit 262 controls the opening and closing of each switch of the switch circuit 25 based on a switch command acquired from the cloud server 4 via the wireless LAN router 3 and the wireless communication unit 242. The switch command includes a lighting command for turning on the lighting device 5 by turning on the switch SW5, a lighting-off command for turning off the lighting device 5 by turning off the switch SW5, an operation command for operating the ventilation fan 6 by turning on the switch SW6, and a stop command for stopping the ventilation fan 6 by turning off the switch SW6.

[0054] The audio output control unit 263 controls the audio output from the speaker 28 based on an audio output command acquired from the cloud server 4 via any one of the wireless LAN router 3 and the wireless communication units 241 to 243 (for example, the wireless communication unit 241, the same hereinafter). As will be described in detail later, the audio output command includes a guidance audio output command for a guidance message and a warning audio output command for a warning message.

[0055] The wireless LAN router 3 is configured to be wirelessly connectable to the shared space terminal 2 (wireless communication units 241 to 243) and the mobile terminal 7 (communication unit 71), and is configured to be communicable with the cloud server 4 (communication unit 41) via a communication network N such as the Internet. The wireless LAN router 3 and the shared space terminal 2 and the mobile terminal 7 are connected by Wi-Fi communication (2.4 GHz). That is, the wireless LAN router 3 is a Wi-Fi router capable of Wi-Fi communication with the wireless communication units 241 to 243. The wireless LAN router 3 and the cloud server 4 are connected by 3G, 4G, LTE, etc., and a modem may be connected between the wireless LAN router 3 and the communication network N as necessary.

[0056] The cloud server 4 includes a communication unit 41, a processing unit 42, and a database 43. The communication unit 41 can communicate with the communication network N either wired or wirelessly. That is, the cloud server 4 can communicate with the administrator terminal 8 and the schedule management application A via the communication network N by means of 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 the data included in the signals transmitted from the shared space terminal 2, the mobile terminal 7, etc.

[0057] The processing unit 42 includes a reservation management unit 420, a display command unit 421, an illumination command unit 422 (switch command unit), a ventilation command unit 423 (switch command unit), a warning processing unit 424, a voice guidance processing unit 425, and a data processing unit 426. The processing unit 42 can also execute general processing functions of a general cloud server, such as overall control of each unit within the cloud server 4 and communication control of the communication unit 41. In other words, the processing unit 42 can appropriately execute various general functions (clock function, timing function, communication control function, arithmetic processing function, etc.) other than the functions of each unit 420 to 426.

[0058] The reservation management unit 420 provides a reservation website for the shared space S to the user's mobile terminal or personal computer (PC), and determines reservation information from user input to the reservation website. Therefore, the reservation management unit 420 holds current and future reservation information about the shared space S. The reservation management unit 420 can perform time management as shown 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 acquires the reservation start time ts and the reservation end time te of the reservation use time from the reservation information, and generates the time t0 associated with the reservation start time ts, and the times t1 to t4 and, if necessary, the time ta associated with the reservation end time te. The times t0 to t4 and ta will be described below.

[0059] 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 minutes to about 10 minutes), and more preferably about 5 to 10 minutes. When the difference time T0-s is 0 minutes, the use of the shared space S before the usage time becomes impossible, and high manageability is achieved. On the other hand, when the difference time T0-s is more than 0 minutes, even before the usage time, the entry and gathering of users are somewhat allowed, and the waiting users outside the shared space S (which may cause noise to the vicinity and interfere with the passage of other users) can be reduced. Thereby, smooth operation regarding the shared space S can be realized while ensuring manageability.

[0060] The time t1 associated with the reservation end time te is the end notice time for notifying the arrival of the reservation end time te before the reservation end time te. The difference time T1-e from the time t1 to the reservation end time te is about 5 to 15 minutes, preferably about 10 minutes. This prompts the user to conclude the meeting and facilitates their smooth preparation for leaving the room.

[0061] The time t2 associated with the reservation end time te is the departure guidance time for prompting the user to leave the room (or exit, the same hereinafter) before the reservation end time te. The difference time T2-e from the time t2 to the reservation end time te is about 1 to 10 minutes, preferably about 5 minutes. This facilitates the user's smooth preparation for leaving the room.

[0062] The time t3 associated with the reservation end time te is the end guidance time for guiding the arrival of the reservation time before the reservation end time te. The difference time T3-e from the time t3 to the reservation end time te is about 0 minutes to 1 minute, preferably about 1 minute. This prompts the user to leave the room immediately.

[0063] The time t4 associated with the reservation end time te is the turn-off time for turning off the lighting device 5 after the reservation end time te. The difference time Te-4 from the reservation end time te to the turn-off time t4 is about 0 to 30 minutes, preferably about 0 to 5 minutes (for example, more than 0 minutes to about 5 minutes), and more preferably about 5 minutes. From the perspective of preventing use after an improper reservation time, 0 minutes (that is, te = t4) is desirable for the difference time Te-4. However, when there is no subsequent reservation, a certain grace period for use may be provided. In order to make the shared space S user-friendly while ensuring manageability, it may be within about 30 minutes.

[0064] The time ta associated with the reservation end time te is a reminder time for promoting an extension reservation before the reservation end time te. However, when there is a reservation for the shared space S after the reservation end time te, the time ta is not generated, or even if it is generated, it is not used. The difference time Ta-e from the time ta to the reservation end time te may be about 15 minutes, and it is desirable to be before the end notice time t1.

[0065] The display command unit 421 generates a console command (the first console command) based on each time and the information on whether extension use 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. Objects 21a to 21j on the console screen 21 are formed by this console command. In addition, the display command unit 421 generates a console command for the mobile terminal (the second console command) for the mobile terminal 7 that has 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 unique 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.

[0066] In addition, the display command unit 421 generates a console command for setting the console screen 21 to standby (for example, blackout) outside the usage time of the shared space S. Even outside the usage time, when a human presence signal is transmitted from the human presence sensor 23b of the shared space terminal 2 or when an operation signal indicating touch detection on the console screen 21 is transmitted, the display command unit 421 generates a console command for displaying 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).

[0067] FIG. 7A shows an example of the console screen 21 of the shared space terminal 2 that has received the console command. As a standard display mode (basic screen) of the console screen 21, for example, there are a screen 21-1 (upper part) corresponding to the console command C1 and a screen 21-2 (lower part) corresponding to the console command C2. On the screen 21-1, the current time display 21a, the reserved end time display 21b, the extension usage guidance display 21c, the remaining time display 21d, the noise level display 21e, the temperature display 21g, the CO2 concentration display 21f, the lighting soft switch 21i, the ventilation soft switch 21j, and the QR code 21k are displayed. On the screen 21-2, the objects 21a to 21k excluding the reserved end time display 21b from the screen 21-1 are displayed. In any of the screens, the objects 21a to 21j among the objects 21a to 21k are referred to as an object group X (first object group).

[0068] FIG. 7B shows an example of the display screen 74 of the mobile terminal 7 that has received a console command for the mobile terminal. On the display screen 74, objects such as the current time display 74a, the extended usage guidance display 74c, the remaining time display 74d, the noise level display 74e, the temperature display 74g, the CO2 concentration display 74f, the lighting soft switch 74i, and the ventilation soft switch 74j are displayed. Note that, as an option, an object 74m for other functions (for example, air conditioning control) may be displayed. Among the objects 74a to 74m, the objects 74a to 74j are referred to as an object group Y (second object group). The console command for the mobile terminal in this case corresponds to the console command C1 or C2. In other words, the reservation end time display may not be displayed on the display screen 74 in FIG. 7B regardless of the presence or absence of the reservation end time display 21b on the console screen 21.

[0069] In this way, the object group Y includes a substantial part of the object group X, the shapes of the objects commonly included in the object group X and the object group Y are substantially the same, and a transfer display from the console screen 21 to the display screen 74 is performed. In the present disclosure, the substantial part of the object group X is defined as more than half of the objects included in the object group X, or the objects included in more than half of the exclusive area of the object group X. Also, the shapes of the objects being substantially the same includes not only the case where the shapes of the two objects are completely the same, but also the case where the shapes of the two objects are similar with a slight difference in the visual perception of the general user.

[0070] FIG. 7C shows an example of the display screen 74 when the mobile terminal 7 is held horizontally (when the longitudinal direction of the display screen 74 faces the horizontal direction). On the display screen 74, objects such as the current time display 74a, the reserved end time display 74b, the extension usage guidance display 74c, the remaining time display 74d, the noise level display 74e, the temperature display 74g, the CO2 concentration display 74f, the lighting soft switch 74i, and the ventilation soft switch 74j are displayed. That is, the console command for the mobile terminal in this case corresponds to the console command C1 (see the screen 21-1 in FIG. 7A). However, when the console command for the mobile terminal corresponds to the console command C2, the reserved end time display 74b is not displayed. In any case, the arrangement of the object group Y (74a to 74j) on the display screen 74 is the same as the arrangement of the object group X (21a to 21j) on the screen 21-1.

[0071] FIG. 7D shows an example of the display screen 74 when the mobile terminal 7 is a tablet terminal. Similar to the case of FIG. 7C, on the display screen 74, objects such as the current time display 74a, the reserved end time display 74b, the extension usage guidance display 74c, the remaining time display 74d, the noise level display 74e, the temperature display 74g, the CO2 concentration display 74f, the lighting soft switch 74i, and the ventilation soft switch 74j are displayed. The console command for the mobile terminal in this case also corresponds to the console command C1 (see the screen 21-1 in FIG. 7A). However, when the console command for the mobile terminal corresponds to the console command C2, the reserved end time display 74b is not displayed. In any case, regardless of the holding direction of the tablet terminal, the arrangement of the object group Y (74a to 74j) on the display screen 74 is the same as the arrangement of the object group X (21a to 21j) on the screen 21-1.

[0072] Alternatively, different from this embodiment, when the console screen 21 is a vertically long screen and the mobile terminal 7 is held vertically (when the longitudinal direction of the display screen 74 faces the vertical direction), the arrangement of the object group Y (74a to 74j) can be the same as the arrangement of the object group X (21a to 21j).

[0073] Here, the shapes of the objects 21a to 21j are each the same (substantially the same) as the shapes of the corresponding objects 74a to 74j. That is, each of the objects included in the object group X has the same shape (substantially the same shape) as each of the objects included in the object group Y. Although not shown in the examples of FIGS. 7A and 7B, when the object group X includes a humidity display 21h instead of the humidity display 21h, the object group Y also includes an object with the same shape humidity display.

[0074] In addition, in the above, in particular, there may be a case where it is preferable that the arrangement (positional relationship) of specific objects in the object group Y is the same as the arrangement (positional relationship) of specific objects in the object group X. For example, it is preferable that the arrangements of the lighting soft switch 21i and the ventilation soft switch 21j are the same as the arrangements of the lighting soft switch 74i and the ventilation soft switch 74j. Thereby, an erroneous operation due to misrecognition between the lighting switch and the ventilation switch can be prevented.

[0075] As described above, the display screen 74 of the mobile terminal 7 is a touch panel and accepts a touch operation by the user. The display command unit 421 generates a console command and a mobile terminal console command for inverting the display of the corresponding objects included in the object groups X and Y in response to a touch operation on the objects included in the object group Y. Operations on each object on the display screen 74 (particularly, switch operations on the lighting soft switch 74i or the ventilation soft switch 74j) are synchronized with operations on the corresponding objects on the console screen 21 (particularly, switch operations on the lighting soft switch 21i or the ventilation soft switch 21j).

[0076] Also, on the display screen 74, in response to a touch on the extended usage guidance display 74c, the display command unit 421 that refers to the reservation management unit 420 generates a console command for a mobile terminal to display an extended reservation screen (not shown) for performing extended usage reservation and settlement on the display screen 74. In the case of the screen of the tablet terminal shown in FIG. 7D, the extended reservation screen may be displayed in the lower area of the basic screen (objects 74a to 74j) at the upper part of the screen. In any case, the user can perform the procedure for extending the usage on the extended reservation screen displayed on the display screen 74. In this way, by actively promoting extended usage to the user, the utilization rate of the shared space S can be improved.

[0077] In this way, the user can operate each object without contact on the console screen 21. Therefore, it is possible to avoid indirect contact among an unspecified number of users via the console screen 21 (including indirect contact with users during other usage times), which is hygienically preferable from the perspective of preventing infectious diseases. Furthermore, since the console screen 21 can be configured with a display without a touch operation function, the cost of the shared space terminal 2 or even the system 1 can be reduced.

[0078] The lighting command unit 422 generates a lighting command and a lighting-off command based on each time generated by the reservation management unit 420 or the switch operation signal transmitted from the shared space terminal 2 (lighting software switch 21i or lighting physical switch 22a). The generated lighting command or lighting-off command is transmitted from the communication unit 41 to the shared space terminal 2 (wireless communication unit 242).

[0079] Specifically, at the lighting time t0, the lighting command unit 422 generates a lighting command. At the reserved start time ts, the lighting command unit 422 temporarily generates a short-time extinguishing 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 extinguished, that is, it blinks or flickers. By this blinking or flickering, the user can visually and intuitively recognize the arrival of the reserved start time ts. At the departure guidance time t2, the lighting command unit 422 temporarily generates a short-time extinguishing command or a lighting command so as to reverse the lighting and extinguishing state of the lighting device 5. Specifically, when the lighting device 5 is in the lighting state, a temporary extinguishing command is generated, and when the lighting device 5 is in the extinguishing state (such as when using a projector), a temporary lighting command is generated. By this blinking or flickering, the user can visually and intuitively recognize the approach of the reserved end time te. These blinks or flickers may be performed once or continuously multiple times (that is, multiple round trips between lighting and extinguishing). At the extinguishing time t4, the lighting command unit 422 generates an extinguishing command.

[0080] Also, during the period within the usage time, when the lighting device 5 is in the lighting state, the lighting command unit 422 generates an extinguishing command according to the switch operation signal, and when the lighting device 5 is in the extinguishing state, the lighting command unit 422 generates a lighting command according to the switch operation signal (that is, reverses lighting and extinguishing). Note that the period within the usage time refers to the period from the lighting time t0 or the reserved start time ts to the reserved end time te or the extinguishing time t4, and the period within the reserved time refers to the period from the reserved start time ts to the reserved end time te.

[0081] On the other hand, during off-usage periods, the lighting command unit 422 temporarily generates a lighting command only for a temporary lighting period in response to a switch operation signal. Here, the off-usage period refers to the period before the lighting time t0 or the period after the extinguishing time t4, and the off-reservation period refers to the period before the reservation start time ts or the period after the reservation end time te. This temporary lighting period is, for example, 10 seconds or more and 1 minute or less, preferably about 20 seconds to 40 seconds, and more preferably about 30 seconds. This temporary lighting period provides temporary lighting for the inspection by the administrator (staff) of the shared space S and the collection of forgotten items by the user. Here, the display command unit 421 may cause the remaining time of the temporary lighting period to be counted down and displayed on the console screen 21 (for example, by the remaining time display 21d). Thereby, the staff or the temporary user can recognize that the current lighting is a temporary lighting. Also, since the staff or the temporary user can know the remaining time until extinguishing, they can act calmly within that remaining time.

[0082] Also, the lighting command unit 422 may be 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 off-usage periods. The above specific operation is, for example, a touch operation on a predetermined location of the console screen 21. This touch operation on the predetermined location may be defined as a touch operation on a single blank location, or may be defined as a simultaneous touch operation on a plurality of blank locations, a plurality of objects, or a combination of a blank location and an object, or a continuous touch operation within a short time. Thereby, in the shared space S, it becomes possible to perform out-of-hours work (cleaning, maintenance, etc.) by work staff such as cleaners and maintenance staff. When extinguishing the light, similar to the extinguishing during usage hours, an extinguishing command is generated by a touch operation on the lighting soft switch 21i. Also, the administrator can manage the working hours of the work staff from the logs of the lighting command and the extinguishing command in this case on the administrator terminal 8.

[0083] The ventilation command unit 423 generates an operation command or a stop command based on the switch operation signal transmitted from the shared space terminal 2 (ventilation soft switch 21j or ventilation physical switch 22b) or the environmental level indicated by the signal transmitted from the shared space terminal 2 (environmental sensor 23a). Alternatively, regardless of the presence or absence of the switch operation signal from the shared space terminal 2 or the environmental level, the ventilation command unit 423 may generate an operation command at regular intervals (e.g., every 30 minutes) for a predetermined period (e.g., 5 minutes) as regular ventilation. The generated operation command or stop command is transmitted from the communication unit 41 to the shared space terminal 2 (wireless communication unit 242).

[0084] The ventilation command unit 423 generates a stop command when the ventilation fan 6 is in the operating state and generates an operation command when the ventilation fan 6 is in the stopped state in response to the switch operation signal (i.e., reverses the operation and stop).

[0085] Further, the ventilation command unit 423 generates an operation command when the detected CO2 level from the CO2 sensor 233 exceeds the 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. In order to avoid frequent repetition of the operation and stop of the ventilation fan 6, the ventilation command unit 423 may generate an operation command when the detected CO2 level exceeds the CO2 rising threshold and generate a stop command when the detected CO2 level falls below the CO2 falling threshold (CO2 rising threshold > CO2 falling threshold). Alternatively, the detection interval of the CO2 sensor 233 or the transmission interval of the detection signal may be set relatively long.

[0086] Furthermore, when the detected pollution level from the IAQ sensor 234 exceeds the pollution threshold (for example, 1100 ppb for VOC), the ventilation command unit 423 generates an operation command, and then, when the detected pollution level from the IAQ sensor 234 falls below the pollution threshold, generates a stop command. In order to avoid repeated frequent operation and stop of the ventilation fan 6, the ventilation command unit 423 may generate an operation command when the detected pollution level exceeds the pollution increase threshold, and generate a stop command when the detected pollution level falls below the pollution decrease threshold (pollution increase threshold > pollution decrease threshold). Alternatively, the detection interval of the IAQ sensor 234 or the transmission interval of the detection signal may be set relatively long.

[0087] When the detected noise level indicated by the signal transmitted from the noise sensor 231 satisfies the noise warning condition, the warning processing unit 424 generates a warning voice output command for emitting a warning message from the speaker 28 of the shared space terminal 2. The warning voice output command is a warning message such as "Please be a little quieter!". Further, an objective index-based message such as "Exceeds XX decibels" may be added to the warning message, thereby ensuring the persuasiveness of the warning. The generated voice output command is transmitted from the communication unit 41 to the shared space terminal 2 (wireless communication unit 241). As a result, the above warning message is output as voice from the speaker 28 by the voice output control unit 263. Here, the noise warning condition is that the cumulative value of the noise level in a continuous time (for example, 3 seconds) exceeds the warning threshold (for example, 85 dB), the peak value of the noise level exceeds a predetermined threshold, and the like.

[0088] In addition, when the above warning is issued, the warning processing unit 424 can notify the administrator's terminal (for example, the administrator terminal 8) of the fact by email or the like. Thereby, the administrator can call the user's mobile terminal 7 or the landline phone arranged in the shared space S and make a request for quietness to the user quickly and directly.

[0089] Further, when the detected CO2 level exceeds the CO2 threshold or the detected contamination level exceeds the contamination threshold, the warning processing unit 424 can generate an audio output command for issuing a warning by voice from the speaker 28. This warning message may simply convey the increase in each detected level, or may prompt ventilation by the ventilation fan 6.

[0090] Based on each time generated by the reservation management unit 420, the voice guidance processing unit 425 generates a voice output command for guidance. The generated voice output command is transmitted from the communication unit 41 to the shared space terminal 2 (wireless communication unit 241). As a result, the warning message is output as voice from the speaker 28 by the voice output control unit 263 of the shared space terminal 2.

[0091] Specifically, at the reservation start time ts, 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 arrived. Please scan the QR code"). Also, at the end notice time t1, the voice guidance processing unit 425 generates a corresponding voice output command for causing the end notice message (for example, "There are 10 minutes left until the end") to be output as voice from the speaker 28. Further, at the departure guidance time t2, the voice guidance processing unit 425 generates a voice output command for outputting a message indicating the approaching reservation end time (for example, "The end time is approaching soon. Please leave promptly"). Furthermore, at the end guidance time t3, the voice guidance processing unit 425 generates a voice output command for outputting a reservation end message (for example, "Thank you for using").

[0092] The data processing unit 426, together with the database 43, provides a graphical display or numerical display of various data to the input / output I / F 84 of the administrator terminal 8 based on the presence or absence of the signal received from the shared space terminal 2 or the detection level indicated by the signal. The graphical display or numerical display includes the real-time monitoring results of the selected items, the statistics of the past monitoring results, etc. The selected items include one or more of noise (the detection result of the noise sensor 231), motion detection (the detection result of the human presence sensor 23b), temperature (the detection result of the temperature and humidity sensor 232), humidity (the detection result of the temperature and humidity sensor 232), CO2 concentration (the detection result of the CO2 sensor 233), and air pollution level (the detection result of the IAQ sensor 234). Further, 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 may be combined in these graphical displays or numerical displays.

[0093] The lighting device 5 is generally an LED lighting fixture, a fluorescent lighting fixture, etc. In this embodiment, since the lighting device 5 is blinked, this embodiment is particularly suitable for an LED lighting fixture with high blinking resistance. The lighting device 5 includes a lighting circuit and a light source (both not shown). One input terminal of the lighting circuit is connected to the AC power supply AC via the switch circuit 25, and the other input terminal is directly connected to the AC power supply AC (see FIGS. 4 and 5). The lighting circuit is a general lighting ballast, which converts the input AC voltage from the AC power supply AC into a predetermined output current and supplies the output current to the light source. For example, when the light source is an LED, the lighting circuit is an electronic ballast including a rectifier circuit and a DC / DC converter. When the light source is a discharge lamp, the lighting circuit is an electronic ballast including a rectifier circuit and a DC / AC converter or a magnetic ballast including a copper-iron coil. Further, the lighting circuit and the light source may be integrated to form a bulb-shaped lighting fixture.

[0094] The ventilation fan 6 is generally a ventilation device that exchanges indoor air with outdoor air. The ventilation fan 6 includes a drive circuit and a motor (both not shown). One input terminal of the drive circuit is connected to the AC power supply AC via the switch circuit 25, and the other input terminal is directly connected to the AC power supply AC (see FIGS. 4 and 5). The drive circuit is a general motor drive circuit that converts the input AC voltage from the AC power supply AC into a predetermined AC current or DC current and supplies its output current to the fan motor (i.e., the fan rotates).

[0095] In addition to the lighting device 5 and the ventilation fan 6, by providing an extended connection terminal block (and the extended terminals included therein) in addition to the connection terminal block 25b (see FIG. 6), other devices (especially existing devices) can be connected. Other devices include a monitor installed outside the shared space S (e.g., on the outer wall surface) that displays the presence / absence of people in the shared space S, reservation information, etc., and an electronic lock installed on the door of the shared space S. Also in this case, for other devices, the power supply wiring is connected or disconnected according to the corresponding switch command from the cloud server 4 (processing unit 42). For example, during the usage time, a display on command is generated as a switch command, and the above monitor is powered on and enters the display state. On the other hand, outside the usage time, a display off command is generated as a switch command, and the above monitor is shut down without being powered on. Also, during the usage time, a locking command is generated as a switch command, and the above electronic lock is powered on and enters the locked (or lock / unlock operable) state. On the other hand, outside the usage time, an unlock command is generated as a switch command, and the above electronic lock is unlocked without being powered on.

[0096] The mobile terminal 7 is a general information communication device such as a smartphone or a 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 the memory 73 are a processor and a memory that constitute a general computer. It is assumed that the necessary application programs are already installed in the memory 73, and the CPU 72 is capable of executing those programs. The display screen 74 is an input / output interface composed of a touch panel as described above.

[0097] The administrator terminal 8 is, for example, a smartphone, a tablet, a personal computer (PC), etc. 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 a memory that constitute a general computer. It is assumed that the necessary application programs are already installed in the memory 83, and the CPU 82 is capable of executing those programs. The input / output I / F 84 is a touch panel when the administrator terminal 8 is a smartphone or a tablet, and is a display device (monitor) and an input device (keyboard, mouse, microphone, etc.) when the administrator terminal 8 is a PC.

[0098] 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, in the reservation management unit 420, the difference time between the lighting time t0 and the reservation start time ts, as well as the difference times between the end notice time t1, the departure guidance time t2, the end guidance time t3, the extinguishing time t4, and the extended acceptance time ta and the reservation end time te can be set or changed. In the display command unit 421, the display content of the console screen 21 (selection of which of the objects 21a to 21k to display) can be set or changed. In the lighting command unit 422, the necessity of a temporary extinguishing command (flashing of the lighting device 5) at the reservation start time ts or the departure guidance time t2 can be set or changed. Also, in the lighting command unit 422, a lighting command or an extinguishing command can be generated manually. In the ventilation command unit 423, the CO2 threshold value, the correction value of the detection level, as well as the necessity of a pollution detection warning (generation of a warning voice output command based on the detected pollution level), and the pollution threshold value can be set or changed. Also, in the ventilation command unit 423, the necessity of regular ventilation (periodic operation of the ventilation fan 6), the necessity of automatic ventilation based on a human presence detection signal (operation of the ventilation fan 6 based on CO2 detection), etc. can be set or changed. Also, in the ventilation command unit 423, an operation command or a stop command can be generated manually.

[0099] Also, in the warning processing unit 424, the necessity of a noise warning (generation of a warning voice output command based on the detected noise level), the necessity of notifying the administrator that a noise warning has been issued, the noise warning conditions, and the correction value of the detection level can be set or changed. Furthermore, the administrator 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 administrator may be able to set or change the warning message substantially in real time via the input / output interface 84, that is, by text input from the keyboard, or by voice input from the microphone and voice recognition processing. Also, in an appropriate functional part of the processing unit 42, the necessity of email notification in the case of any indoor abnormality detection based on a specific detection level and the necessity of email notification in the case of out-of-hours entry detection can be set or changed.

[0100] Figure 8 shows the flow of processes executed among the shared space terminal 2, the cloud server 4, and the mobile terminal 7 in the system 1. Here, an example is shown in which the lighting device 5 is turned on and off from the mobile terminal 7 within the reserved time of the shared space S.

[0101] Step S10 is executed at the reservation start time ts. In step S10, the cloud server 4 (display command unit 421) generates and transmits a console command for the basic screen (see FIG. 7A, but each numerical value is different) to the shared space terminal 2.

[0102] In step S12, the shared space terminal 2 (console control unit 261) causes the basic screen (see FIG. 7A, but each numerical value is different) corresponding to the console command generated in step S10 to be displayed on the console screen 21.

[0103] In step S14, it is assumed that the user captures the QR code 21k on the console screen 21 using the mobile terminal 7 (camera 75). As a result, the mobile terminal 7 transmits the QR code 21k and the identification information of the mobile terminal 7 to the cloud server 4.

[0104] In step S16, the cloud server 4 (display command unit 421) generates and transmits a console command for the mobile terminal corresponding to the console command generated in step S10 to the mobile terminal 7.

[0105] In step S18, the mobile terminal 7 causes a screen (see FIG. 7B, but each numerical value is different) corresponding to the console command for the mobile terminal generated in step S16 to be displayed on the display screen 74.

[0106] In step S20, it is assumed that the user touches the lighting soft switch 74i on the mobile terminal 7 (display screen 74). As a result, the mobile terminal 7 transmits a lighting operation signal to the cloud server 4.

[0107] In step S22, the cloud server 4 (lighting command unit 422) generates and transmits a switch command (lighting command if in the off state, off command if in the on state) for reversing the on / off state of the lighting device 5 to the shared space terminal 2. Also, the cloud server 4 (display command unit 421) generates and transmits a console command and a console command for the mobile terminal for reversing the display of the lighting soft switches 21i and 74i to the shared space terminal 2 and the mobile terminal 7, respectively.

[0108] In step S24, the shared space terminal 2 (switch control unit 262) controls the switch circuit 25 to reverse the on / off state of the lighting device 5 in response to the switch command generated in step S22. Also, the shared space terminal 2 (console control unit 261) reverses the display of the lighting soft switch 21i in response to the console command generated in step S22. In step S26, the mobile terminal 7 (CPU 72) also reverses the display of the lighting soft switch 74i in response to the console command for the mobile terminal generated in step S22. Note that when the operation of the ventilation fan 6 is / stopped is operated from the mobile terminal 7 within the usage time of the shared space S, the flow is substantially the same.

[0109] Also, in step S28, it is assumed that the user touches the extended usage guidance display 74c on the mobile terminal 7 (display screen 74). Thereby, the mobile terminal 7 transmits a signal requesting a screen for extended usage reservation to the cloud server 4.

[0110] In step S30, the cloud server 4 (display command unit 421 referring to the reservation management unit 420) generates and transmits a console command for the mobile terminal for displaying a screen for extended usage reservation to the mobile terminal 7. In response to this, in step S32, it is assumed that the user inputs and settles an extended reservation on the screen for extended usage reservation.

[0111] At the extended reservation end time te, in step S34, the cloud server 4 (display command unit 421) generates and transmits a console command and a console command for the mobile terminal to the shared space terminal 2 and the mobile terminal 7, respectively, for displaying an end screen for overtime use (see, for example, FIG. 10D described later). Further, the cloud server 4 releases the synchronization between the console screen 21 and the display screen 74, that is, does not display the object group Y on the display screen 74. Thereafter, the shared space terminal 2 (console control unit 261) and the mobile terminal 7 (CPU 72) perform displays according to the console command and the console command for the mobile terminal, respectively. That is, after the reservation end time te, the cloud server 4 causes a separate screen (for example, a screen indicating the end of the use of the shared space S, an initial screen at the start of the use of the shared space S, etc.) that is not synchronized with the console screen 21 to be displayed on the display screen 74.

[0112] FIG. 9 shows an example of the operation timeline of the system 1. In the reservation information of this example, it is assumed that the reservation start time is 14:00 and the reservation end time is 15:00. Further, it is assumed that there is no reservation for the shared space S from 15:00 onwards until 18:30 and extended use is possible.

[0113] The lighting time t0 is 13:55, which is 5 minutes before the reservation start time ts in this example. At the lighting time t0, the switch control unit 262 turns on the switch SW5 of the switch circuit 25 according to the lighting command to turn on the lighting device 5. At this point, the console control unit 261 causes a preparation screen including a logo related to the system 1, the shared space terminal 2, or the shared space S to be displayed on the console screen 21. At this point, if it is before the end time of the previous reservation, the lighting device 5 is already lit, so the lighting command is not generated. Further, the console screen 21 continues to display the screen related to the previous reservation.

[0114] At the reservation start time ts, the switch control unit 262 temporarily turns off the switch SW5 of the switch circuit 25 according to a temporary lighting-off command to blink the lighting device 5. At the reservation start time ts, the console control unit 261 causes the basic screen 2101 shown in FIG. 10A to be displayed on the console screen 21 according to a console command. In this basic screen 2101, the current time display 21a indicates "14:00", the extended usage guidance display 21c indicates "18:30", and the remaining time display 21d indicates "01:00" (it may also be "00:60" or "00:59"). The noise level display 21e, the temperature display 21g, and the humidity display 21h indicate "62 dB", "24 °C", and "50%", respectively. The lighting soft switch 21i indicates the lighting state, and the ventilation soft switch 21j indicates the stopped state. At the reservation start time ts, the voice output control unit 263 causes a voice message such as "The start time has arrived. Please scan the QR code" to be output from the speaker 28 according to a guidance voice output command.

[0115] When the user scans (captures) the image code display 21k of the basic screen 2101 using the camera 75 of the mobile terminal 7, the CPU 72 of the mobile terminal 7 accesses the website provided by the cloud server 4. The basic screen 7401 shown in FIG. 10B is displayed on the display screen 74 according to the console command for the mobile terminal generated by the display command unit 421. The object group displayed on the basic screen 7401 includes the object group of the basic screen 2101 excluding the image code display 21k.

[0116] Thereafter, during the use of the shared space (until the end guidance time t3 or the reservation end time te described later), the console screen 21 of the shared space terminal 2 and the display screen 74 of the mobile terminal 7 maintain the forms of the basic screen 2101 and the basic screen 7401, respectively, and the numerical values of the current time display 21a and the remaining time display 21d change with time (see FIGS. 7A and 7B). Also, changes occurring in the noise level display 21e, the temperature display 21g, the humidity display 21h, the lighting soft switch 21i, or the ventilation soft switch 21j are synchronized between the screen 2101 and the screen 7401.

[0117] At the extended guidance time ta, the console control unit 261 causes the console screen 21 to display the screen 2102 shown in FIG. 10C according to the console command. On the screen 2102, a remaining time display 21d ("00:15"), an extended usage guidance display 21c ("18:30"), and an enlarged image code (QR code) 21k' are displayed, and a message prompting extension such as "If you wish to extend, please scan the QR code with your mobile phone." is displayed together with the QR code 21k'. This message may be output as voice from the speaker 28.

[0118] In this example, it is assumed that the user did not scan (image) the QR code 21k' on the screen 2102. That is, the extended usage reservation is not made, and the initial reservation end time te is applied.

[0119] The end notice time t1 is 14:50, which is 10 minutes before the reservation end time te in this example. At the end notice time t1, the voice output control unit 263 outputs a voice message such as "It will end in 10 minutes" from the speaker 28 according to the guidance voice output command.

[0120] The departure guidance time t2 is 14:55, which is 5 minutes before the reservation end time te in this example. At the departure guidance time t2, the switch control unit 262 temporarily turns off the switch SW5 of the switch circuit 25 according to a temporary lighting-off command to blink the lighting device 5. When the lighting device 5 is in the lighting-off state, the switch control unit 262 temporarily turns on the switch SW5 of the switch circuit 25 according to a temporary lighting-on command to blink the lighting device 5. The voice output control unit 263 outputs a voice message such as "The end time is approaching soon. Please leave promptly." from the speaker 28 according to the guidance voice output command.

[0121] The end guidance time t3 is 14:59, one minute before the reservation end time te, in this example. At the end guidance time t3, the voice output control unit 263 causes the speaker 28 to output a voice message such as "Thank you for using. The lighting will turn off in 5 minutes" according to the guidance voice output command. If the lighting device 5 has already been turned off by the user's switch operation, the voice message will be only "Thank you for using". At the end guidance time t3 or the reservation end time te, the console control unit 261 causes the screen 2103 shown in FIG. 10D to be displayed on the console screen 21 according to the console command. The logo, the current time display 21a, the noise level display 21e, the temperature display 21g, the humidity display 21h, the lighting soft switch 21i, or the ventilation soft switch 21j are displayed on the screen 2103. On the display screen 74 of the mobile terminal 7, for example, the current time, the above logo, and a message such as "Thank you for using. We are looking forward to your next use" are displayed. At this point, the synchronization between the console screen 21 and the display screen 74 is released.

[0122] The light-off time t4 is 15:05, five minutes after the reservation end time te, in this example. At the light-off time t4, the switch control unit 262 turns off the switch SW5 of the switch circuit 25 according to the light-off command to turn off the lighting device 5.

[0123] In addition, if the user scans the QR code 21k' on the screen 2102 within the reservation time (for example, after the extension guidance time ta), an extension reservation screen is displayed on the display screen 74. If the settlement by the user for the extension reservation is completed on this extension reservation screen, the extended use reservation is determined. Accordingly, new times t1 to t4 are reset based on the new reservation end time te after the extension. Therefore, based on the new times t1 to t4 and the initial time ta, the same operation as above is executed. However, the extension guidance time ta may change depending on the reservation status of other users thereafter.

[0124] In addition, if there is another reservation immediately after the reservation end time te, the extension usage guidance display 21c on the console screen 21 (basic screen 2101) and the extension usage guidance display 74c on the display screen 74 (basic screen 7401) will be "not available". Therefore, even if the extension usage guidance display 21c or 74c is touched, the extension reservation screen will not be displayed. Also, the extension guidance time ta is not adopted, and the screen 2102 is not displayed either. In this case, the light-off at time t4 is not performed, and the voice output at time t3 does not mention the light-off.

[0125] <Summary of the Embodiment> As described above, the system 1 of this embodiment includes a shared space terminal 2 arranged in the shared space S and a cloud server 4 connected to be wirelessly communicable with the shared space terminal 2. The shared space terminal 2 includes a console screen 21, a console control unit 261 that displays the object group X and the QR code 21k on the console screen 21 based on a console command received from the cloud server 4, and a switch control unit 262 that controls loads (5, 6) installed in the shared space S based on a switch command received from the cloud server 4. The cloud server 4 includes a display command unit 421 that generates a console command for displaying the object group X and the QR code 21k as images, and a mobile terminal console command for synchronously displaying an object group Y including a substantial part of the object group X on the display screen 74 of the mobile terminal 7 that has captured the QR code 21k on the console screen 21, and a switch command unit (422, 423) that generates a switch command in response to a touch operation on a predetermined object included in the object group Y. The shapes of the objects commonly included in the object group X and the object group Y are substantially the same.

[0126] Also, the shared space operation method of this embodiment includes: (S10) a step in which the cloud server 4 transmits a console command for displaying the object group X and the object 21k of the image code to the shared space terminal 2; (S12) a step in which the shared space terminal 2 displays the object group X and the object 21k of the image code on the console screen 21 based on the console command; (S14) in response to the mobile terminal 7 capturing the object 21k of the image code, (S16) a step in which the cloud server 4 transmits a console command for the mobile terminal for synchronously displaying an object group Y including a substantial part of the object group X to the mobile terminal 7; (S20) in response to a touch operation on a predetermined object included in the object group Y, (S22) a step in which the cloud server 4 transmits a switch command to the shared space terminal 2; and (S24) a step in which the shared space terminal 2 controls the loads (5, 6) installed in the shared space S based on the switch command. The shapes of the objects commonly included in the object group X and the object group Y are substantially the same.

[0127] According to the above system 1 and the shared space operation method, an object group Y including a substantial part of the object group X on the console screen 21 is synchronously displayed on the display screen 74 of the mobile terminal 7 that has captured the object 21k of the image code in substantially the same shape. Then, a switch command is generated in response to a touch operation on the object (74i, 74j) of the switch button included in the object group Y displayed on the display screen 74 of the mobile terminal 7, and accordingly, the loads (5, 6) installed in the shared space S are turned on / off. Thereby, the system 1 is realized that enables the user of the shared space S to use the functions of the shared space terminal 2 in a non-contact manner and with a high sense of connection with respect to the shared space terminal 2.

[0128] The load is the lighting device 5 installed in the shared space S. Each of the object groups X and Y includes lighting soft switches 21i and 74i related to the lighting or extinguishing of the lighting device 5. The lighting command unit 422 is configured to generate a switch command for lighting or extinguishing the lighting device 5 in response to a touch operation on the lighting soft switch 74i included in the object group Y. Since the lighting device 5 is an essential load in the shared space S, a highly versatile system 1 useful for any shared space S is realized.

[0129] The load is the ventilation fan 6 installed in the shared space S. Each of the object groups X and Y includes a ventilation soft switch 21j related to the operation or stop of the ventilation fan 6. The ventilation command unit 423 is configured to generate a switch command for operating or stopping the ventilation fan 6 in response to a touch operation on the ventilation soft switch 74j included in the object group Y. Since ventilation is essential in the shared space S used by an unspecified number of users, a highly versatile system 1 useful for any shared space S is realized.

[0130] The display command unit 421 is configured to generate a console command and a console command for a mobile terminal to reversely display the object of the switch button (21i, 21j, 74i, 74j) included in the object groups X and Y in response to a touch operation on the object of the switch button (74i, 74j) included in the object group Y. Thereby, the sense of link from the mobile terminal 7 to the shared space terminal 2 is enhanced.

[0131] Each of the object groups X and Y preferably includes (a) an object for displaying the current time, (b) an object for displaying the reservation end time of the shared space, (c) an object for displaying whether extension use of the shared space is possible or the final possible use time when extension use is possible, and (d) an object for displaying the remaining time corresponding to the value obtained by subtracting the current time from the reservation end time. Thereby, comprehensive information regarding the reservation of the shared space is displayed, and the information regarding the reservation becomes more listable.

[0132] Each of the object groups X and Y preferably includes (a) an object for displaying the current time, (c) an object for displaying whether extension use of the shared space is possible or the final possible use time when extension use is possible, and (d) an object for displaying the remaining time obtained by subtracting the current time from the reservation end time. Thereby, the minimum necessary information regarding the reservation of the shared space is displayed, and in particular, the space on the display screen of the mobile terminal can be effectively used.

[0133] The display command unit 421 is configured to generate a mobile terminal console command for causing the mobile terminal 7 to display a screen for extension use reservation on the display screen 74 of the mobile terminal 7 in response to a touch operation on the object 74c included in the object group Y. In other words, the shared space operation method further includes a step (S30) in which the cloud server 4 transmits a mobile terminal console command for causing the mobile terminal 7 to display a screen for extension use reservation on the display screen 74 of the mobile terminal 7 in response to a touch operation on the object (c) included in the object group Y. Thereby, the extension use of the shared space can be promoted and its utilization rate can be improved.

[0134] It is preferable that the positional relationship between the first and second objects (for example, the lighting soft switch 21i and the ventilation soft switch 21j) included in the object group X is the same as the positional relationship between the third and fourth objects (the lighting soft switch 74i and the ventilation soft switch 74j) included in the object group Y and corresponding to the first and second objects. In this way, by making the positional relationship of specific objects the same between the object group X and the object group Y, erroneous operations due to misrecognition between specific objects can be prevented.

[0135] It is preferable that the positional relationship of all the objects included in the object group X is the same as the positional relationship of all the objects included in the object group Y. Thereby, the sense of link from the mobile terminal 7 to the shared space terminal 2 is further enhanced.

[0136] The object group Y is displayed on the display screen 74 only between the reservation start time and the reservation end time of the shared space. This ensures the manageability of the reservation use of the shared space S.

[0137] <Modification example> Although the preferred embodiments of the present invention have been shown above, the present invention can be modified into various aspects as shown below, for example.

[0138] (1) Modification regarding the shared space S In each of the above embodiments, the case where the shared space S is a rental conference room has been shown. However, the shared space terminal 2 and the shared space operation system 1 can be applied to any space that can be rented for the time when lighting is required. 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 food and beverage space, etc.

[0139] (2) Modification regarding the communication standard In each of the above embodiments, the configuration in which the wireless communication unit 24 (241 to 243) and the wireless LAN router 3 perform Wi-Fi communication has been shown. However, as long as the same wireless communication function can be realized, other existing or future-developed communication standards may be adopted. For example, in this embodiment, Wi-Fi communication in the 2.4 GHz band is adopted, but Wi-Fi communication in the 5 GHz band may be adopted. Also, a mobile SIM may be used for the wireless communication unit 24. In this case, since the shared space terminal 2 and the communication network N (cloud server 4) are directly wirelessly communication-connected, the wireless LAN router 3 becomes unnecessary. Also, the mobile terminal 7 may be located inside the shared space S and directly communicate with the communication network N without going through the wireless LAN router 3.

[0140] (3) Modification 1 regarding noise warning In each of the above embodiments, as a noise warning when the detected noise level exceeds the warning threshold, a configuration is shown in which a warning message is output as voice. However, the configuration may be such that the display on the console screen 21 changes. For example, as a noise warning, the warning processing unit 424 and the display command unit 421 may enlarge and display the noise level display 21e (for example, only the noise level display 21e) on the console screen 21. Also, after the user scans the image code display 21k with the mobile terminal 7, as a noise warning, the warning processing unit 424 and the display command unit 421 may enlarge and display the noise level display 74e (for example, only the noise level display 74e) on the display screen 74. Further, the warning processing unit 424 may vibrate (vibrate) the mobile terminal 7 in conjunction with this. Also, the warning processing unit 424 and the display command unit 421 may cause the noise level display 21e or 74e before or after enlargement to blink. Thereby, the user's recognition of the increase in the noise level is further enhanced.

[0141] (4) Variation 2 Regarding Noise Warning In each of the above embodiments, as a noise warning when the detected noise level exceeds the warning threshold, a configuration is shown in which a warning message is output as voice. On the other hand, when the number of warning messages issued before the extension guidance time ta exceeds a predetermined number, even if extension use is possible, a configuration may be adopted in which extension use guidance is not performed. For example, in the above case, the warning processing unit 424 and the display command unit 421 may display the extension use guidance display 21c on the console screen 21 as "not available" regardless of whether extension use is possible, or may not display the extension use guidance display 21c itself. Along with this, the display command unit 421 does not display the screen (screen 2102 in FIG. 10C) that should have been displayed at the extension guidance time ta. Also, even after the image code display 21k is scanned by the mobile terminal 7, the extension use guidance display 74c on the display screen 74 may be displayed as "not available", or the extension use guidance display 74c itself may not be displayed. Thereby, the user's extension use that may cause noise trouble is blocked, and comfortable use by users of other shared spaces S in the vicinity is ensured.

[0142] (5) Variation 3 Regarding Noise Warning In each of the above embodiments, a configuration in which the necessity of warning and the warning threshold are changeable fixed values has been shown. However, the necessity of warning or the warning threshold may be variable according to the usage status of other shared spaces S in the vicinity. For example, when the shared space S2 in the vicinity (for example, adjacent) of the reserved target shared space S1 is vacant, the warning processing unit 424 may make the necessity of warning for the target shared space S1 unnecessary or increase the warning threshold. Therefore, even in one usage time zone of the target shared space S1, the necessity of warning or the warning threshold can be automatically changed according to the usage status of the adjacent shared space S2. Whether the adjacent shared space S2 is vacant or not can be determined from the reservation information obtained from the reservation management unit 420 or the detection result of the human presence sensor 23b. Thereby, in a case where the adjacent shared space S2 is vacant, etc., the noise of the user of the target shared space S1 can be tolerated within a range where no actual harm occurs, and active discussions, smooth communication, etc. can be promoted.
