[0003] [Patent Document 1] JP 2004-86582 A Summary of the Invention [Problem to be solved by the invention]

[0004] An event requiring evacuation may occur while using a space designed to avoid distracting from surrounding sounds. Alarm sounds are often used to notify the occurrence of an event, but even if an alarm sound is broadcast outside the space, it is difficult for users inside the space to notice it. This is especially true if users are wearing headphones or earphones.

[0005] The present invention aims to provide a function that encourages the evacuation of users of an installed space that is separated from the surrounding area by closing the entrance / exit door in the event of an event requiring evacuation. [Means for solving the problem]

[0006] Claim 1The invention described in is a device that is connected via a network to an installed space that is separated from the surrounding area by closing the entrance door, and has a control means that, when information received when a user's entry into the unlocked space is detected by the terminal of the user who has reserved the space meets a predetermined event criterion, outputs a notification urging the user to leave through equipment installed in the space or the user's terminal, and urges the user to leave. If the user's departure from the space is not detected by the output of a sensor installed in the space within a predetermined first period from the output of an alarm sound from a speaker as one of the equipment or a speaker installed in the user's terminal, the control means increases the volume of the alarm sound, changes the pattern of the output cycle of the alarm sound, or changes the pattern of the sound range of the alarm sound, and if the user's departure is not detected within a second period from the increase in the volume of the alarm sound, the change in the pattern of the output cycle, or the change in the pattern of the sound range, the control means notifies a system or administrator that manages the space. Claim 2 The invention described in claim 2 is characterized in that the control means controls the second period to be shorter than the first period. 1 The device is described in Claim 3 The invention described in claim 2 is characterized in that the control means outputs the informative sound in the first period at a first interval, and outputs the informative sound in the second period at a second interval that is shorter than the first interval. 1 The device is described in Effect of the Invention

[0007] Claim 1 According to the described invention, it is possible to notify the manager of the presence of users who do not evacuate. Claim 2 The described invention makes it easier to notice situations that require evacuation. Claim 3 The described invention makes it easier to notice situations that require evacuation.

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. <Embodiment 1> <Overall configuration of the management system> With the increase in communication speed and the miniaturization of communication terminals, it is now possible to access various information even outside the office. However, because business conversations and information are highly confidential, a quiet and secure environment is required. In this embodiment, a management system for providing a space that meets these demands will be described. However, the space described below is not limited to business use, and can also be used by individuals. This type of space is also called a booth.

[0010] FIG. 1 is a diagram illustrating an example of the overall configuration of a management system 1. As shown in FIG. As shown in FIG. 1, the management system 1 is composed of a terminal connected to a communication network 2 and a terminal connected to a disaster prevention communication network 3. Both the communication network 2 and the disaster prevention communication network 3 include wired communication and wireless communication. The communication network 2 is, for example, the Internet or a mobile communication network. The disaster prevention communication network 3 is, for example, a disaster prevention radio network (disaster prevention administrative radio, regional satellite communication network, fire and disaster prevention radio, central disaster prevention radio, regional administrative radio, etc.). In this embodiment, the communication network 2 used for communication with communication devices that are given priority in the event of a disaster is also treated as the disaster prevention communication network 3.

[0011] The disaster prevention communication network 3 is connected to a disaster prevention system operated by an administrative agency, and is used for communicating various disaster information and disaster-related information between bases. Disaster prevention systems include systems installed in so-called designated administrative agencies, such as the central government ministries and agencies including the Japan Meteorological Agency, and systems installed in local administrative agencies such as prefectures and municipalities. Disaster information is information relating to wide-area crises and disasters, and includes information that changes in real time, such as warnings, alerts, evacuation recommendations, emergency earthquake alerts, prediction information, and evacuation information. Disasters in this embodiment include, for example, storms, heavy rain, heavy snow, floods, high tides, earthquakes, tsunamis, volcanic eruptions, other abnormal natural phenomena, large-scale fires, large-scale explosions, large-scale accidents, and security risks.

[0012] The terminals shown in Figure 1 include multiple work spaces 4, multiple user terminals 5 used by individual users who use the work spaces 4, a reservation management server 6 that manages reservations for each work space 4, a billing management server 7 that manages billing for users, a member management server 8 that manages information on members who can use the work spaces 4, a crisis / disaster management server 9 that manages the occurrence of events that require users to evacuate (evacuation-requiring events), and a facility-side disaster management server 10 that is installed on the facility side in which the work spaces 4 are installed.

[0013] The work space 4 in this embodiment is a space that is separated from the surroundings by closing the door at the entrance, and is available for use by those who have made a reservation. The work space 4 can be brought in and set up in any location. In this embodiment, the workspace 4 is rented out to a person who reserves the space for a predetermined period of time. The time during which the person who reserves the space can use the space varies depending on the location where the workspace 4 is installed and the policy of the operator. For example, the space can be used 24 hours a day, 365 days a year, except for times when the space is used for maintenance, etc. In this embodiment, the work space 4 is placed in places with a lot of human traffic, such as train stations, airports, underground shopping malls, office buildings, department stores, hospitals, shopping streets, banks, libraries, art galleries, museums, public institutions and facilities, connecting corridors, parks, etc., whether indoors or outdoors. 1 shows an example in which a plurality of workspaces 4 are installed in a building. Of course, the workspace 4 may be installed in one location.

[0014] The work space 4 in this embodiment may be structurally connectable to another work space 4. The work spaces 4 in this embodiment include a work space 4 for one person and a work space 4 for multiple people. In the working space 4 of this embodiment, facilities such as a working desk, lighting, speakers, a monitor, a keyboard, a mouse, and a power strip are provided. Furthermore, in the work space 4, wiring for supplying power, wiring for controlling the operation of the installed devices, etc. are provided. The work space 4 in this embodiment is an example of a device having a communication function.

[0015] In the case of FIG. 1, one server is provided for each purpose (function), but multiple servers may be provided for each purpose. Also, a single server may serve multiple purposes (functions). For example, a single server may provide the functions of the reservation management server 6, the billing management server 7, and the member management server 8. The business providing the hourly rental service of the workspace 4 may be a single business or multiple businesses. For example, different businesses may share the management of reservations, management of entry / exit and room usage, management of billing of usage fees to users, and management of members registered as users. Note that management of one purpose (function) may be provided collaboratively by multiple businesses. When a single business entity provides multiple servers for one purpose (function) or multiple servers for multiple purposes (functions), they can be connected via an intranet. Furthermore, the workspace 4 may be provided not only by a single business operator, but also by a plurality of business operators. In other words, the management system 1 may be realized as a collection of services provided by a plurality of businesses.

[0016] In this embodiment, the crisis / disaster management server 9 is operated by a business operator that provides hourly rental services for the workspace 4. The operator of the crisis / disaster management server 9 may be another business operator that has a partnership with the business operator that provides hourly rental services for the workspace 4. The crisis / disaster management server 9 is a server that manages information relating to wide-area crises and disasters notified from the disaster prevention communication network 3 . When the crisis / disaster management server 9 receives information about a wide-area crisis or disaster, it notifies the workspace 4 to be managed and the user terminal 5, which is the user thereof, via the communication network 2. The user terminal 5 is an example of an information device used by a user. Information on wide-area crises and disasters includes, for example, earthquakes, tsunamis, wind and flood damage, volcanoes, heavy rain, and typhoons, as well as evacuation preparations, evacuation advisories, and evacuation orders issued based on them.

[0017] In this embodiment, the crisis / disaster management server 9 can cooperate with the facility-side disaster management server 10, and they are connected to each other via a communication line 11. Alternatively, the crisis / disaster management server 9 and the facility-side disaster management server 10 are connected via a communication network 2. Note that the communication line 11 is not limited to being wired, and may be realized by a wireless system. The facility-side disaster management server 10 is a server that manages information regarding wide-area crises and disasters received through the disaster prevention communication network 3, as well as information regarding local crises and disasters within the building or other facility in which the workspace 4 is located. Information about localized hazards or disasters includes, for example, fires, water leaks, gas leaks, flooding, and landslides. The facility-side disaster management server 10 is connected to the work space 4 via a communication line 12. In the case of this embodiment, the communication line 12 is made of, for example, an electric wire, an optical fiber, a coaxial cable, or an alarm cable that has excellent fire resistance and heat resistance. In this embodiment, communication via the communication line 12 has a higher availability than communication via the communication network 2 .

[0018] In this embodiment, an electronic key is used to lock and unlock the work space 4. The electronic key is stored in the user terminal 5 or an IC (Integrated Circuit) card (not shown) compatible with short-range wireless communication. In the case of this embodiment, a portable device is used as the user terminal 5. Examples of portable devices include, for example, a notebook computer and a smartphone. When the user terminal 5 is used as an electronic key, the electronic key is provided to the user terminal 5 from the reservation management server 6 after the reservation is confirmed. When an IC card is used as an electronic key, after the reservation is confirmed, the reservation management server 6 distributes an IC card on which the electronic key is recorded to the user who made the reservation. In the case of electronic keys, the time during which locking and unlocking can be performed effectively can be freely determined. Also, multiple electronic keys required for use of one workspace 4 can be issued for the same time period. Note that multiple physical keys may be prepared for different reserved times to lock or unlock the workspace 4. Also, the authentication information of the user may be used instead of a key, or the authentication information may be used as a means to supplement the electronic key or physical key.

[0019] The reservation management server 6 manages, for example, a registration list in which available workspaces 4 are registered, and a reservation list that manages the allocation of users who wish to use each workspace 4. In this embodiment, the reservation management server 6 accepts reservations for the workspace 4 24 hours a day, 365 days a year, except for times set aside for maintenance, etc. In addition, the reservation management server 6 issues electronic keys to the user terminal 5 and executes authentication processing as necessary. Furthermore, the reservation management server 6 manages, for example, information for managing users' entry and exit to the work spaces 4 and information on the usage status of each of the work spaces 4. Furthermore, the reservation management server 6 also has a function of communicating with an authentication unit arranged in the work space 4 and managing whether or not a user is permitted to enter the work space. The reservation management server 6 in this embodiment is provided with a function to estimate the number of users present in the workspace 4, and a function to compare the number of people reserved with the number of users present in the workspace 4. The estimated number of people and the results of the comparison are shared with the crisis / disaster management server 9. The reservation management server 6 in this embodiment has the function of collecting information from the various devices arranged in the work space 4 and controlling the various devices. Part of the functions of the reservation management server 6 may be accommodated in the work space 4.

[0020] The billing management server 7 has a function of issuing invoices for each member based on reservation information, user information, entry and exit information, etc. A member may be either a natural person or a corporation. The billing management server 7 obtains reservation information and entry and exit information from the reservation management server 6, and obtains member information from the member management server 8. The member management server 8 manages registered member information and user information. When a member is a natural person, the member and the user are the same. On the other hand, when a member is a corporation, each user is registered and managed separately for each member.

[0021] <Work space 4 configuration> Here, the configuration of the work space 4 will be described with reference to FIGS. Fig. 2 is a diagram for explaining an example of the external appearance of the work space 4 when the door is closed. Fig. 3 is a diagram for explaining an example of the external appearance of the work space 4 when the door is open. In the present embodiment, the work space 4 is assumed to be a small room with excellent soundproofing. In this sense, the work space 4 is an example of a closed space. In the present embodiment, the term "closed" is used to mean having practical soundproofing and ventilation capabilities, not airtightness. Therefore, openings or gaps such as vents or small windows may be provided in a portion of the body 30 that constitutes the working space 4.

[0022] In this embodiment, the main body 30 is composed of a ceiling 30A, a floor 30B, a wall 30C to which an openable and closable door 32 is attached, two walls 30D and 30E located on either side of wall 30C, and a wall 30F located on the opposite side of door 32. The walls 30C, 30D, 30E, and 30F function as partition walls that separate the exterior space from the interior space. In this embodiment, the door 32 is a sliding door and is attached along the wall surface 30C so as to be openable and closable. The arrow in Fig. 3 indicates the direction in which the door 32 opens. The sliding door may be a single-sliding type as shown in Figs. 2 and 3, a sliding type in which two or more members pass each other to open and close, or a separate type in which two doors slide left and right. When the door 32 moves to the open position, an entrance for a user to enter and exit appears.

[0023] The door 32 may be a single-leaf door that opens and closes by drawing an arc with one door member. In this case, the door 32 may be either inward-opening or outward-opening. The door 32 may also be a double-leaf door that separates one opening with two door members. The door 32 may be a folding door that opens by folding a pair of door members connected by a hinge. There are two types of folding doors: one that opens in one direction and one that opens in both directions. As a special type, the door 32 may be a sliding door or a partition door that can be retracted into the wall when stored.

[0024] In this embodiment, the door 32 is provided with a handle 32A that the user grasps when opening or closing the door. In addition, a member 32B that has been processed to ensure secrecy and crime prevention is placed in the center of the door 32. The member 32B may be, for example, a transparent plate with a metal plate (for example, punched metal) with a large number of holes arranged on the inside attached to the inside, a transparent plate with a member that acts as a screen attached to the inside with a gap, a transparent plate with a film attached that makes it easy to check the inside from the front but difficult to check the inside from an oblique direction, or a transparent plate that has been processed to reduce the visibility of the inside. For example, glass or acrylic resin is used for the transparent plate.

[0025] The film here may be a liquid crystal film that can be electrically switched between transparent and opaque, or a polarizing film whose transmittance can be electrically controlled. Furthermore, processing to reduce visibility includes, for example, making fine scratches on the surface of a member so as to scatter light. The processing may be a part of the member 32B. For example, the floor and the vicinity of the ceiling may be transparent, but the area through which the monitor can be seen during work may be hidden by an opaque member. By disposing the member 32B, it becomes possible to confirm from the outside whether the user is present or not while hiding the monitor screen from the outside. In addition, the door 32 is fitted with an electronic lock 32C that can be unlocked with an electronic key.

[0026] The number of users of the work space 4 is roughly determined by its volume. In this embodiment, a private room for one person is basically assumed, but a large room that can accommodate many people may also be used. The large room may be configured as a single room, or may be configured by removing one or more of the walls 30D, 30E, and 30F of the work space 4 and connecting them. Please note that the term "private room" does not mean that it can only be used by one person, but rather that it can accommodate a small number of people, for example 2-3 people. The shape and structure of the framework 30 constituting each work space 4, and the facilities and performance provided therein are arbitrary. A ventilation opening 33 is provided in the ceiling 30A. In the case of Figures 2 and 3, a louver 33A capable of adjusting the opening area is attached to the ventilation opening 33. The louver 33A in Figures 2 and 3 is in a fully open state. In this embodiment, an indicator light 34 used to notify the state inside the workspace 4, such as the presence or absence of a user, is attached to the outside of the wall surface 30D. The indicator light 34 here is an example of a notification means.

[0027] Next, the internal configuration of the work space 4 will be described. 4A and 4B are diagrams illustrating an example of the internal configuration of the work space 4. (A) is a diagram showing the inside of the work space 4 with the ceiling 30A removed, and (B) is a diagram showing the inside of the work space 4 with the wall surface 30C on which the door 32 is provided removed. In this embodiment, one desk 35 and one chair 36 are arranged inside the work space 4. In the case of Fig. 4, the desk 35 is attached to the wall surface 30D, but it may be attached to the floor surface 30B or may be arranged movably on the floor surface 30B. On the desk 35, there are arranged a keyboard 37 as input devices, a mouse 38, a monitor 39, and a computer (not shown). The monitor 39 may be fixed to the wall surface 30D or the desk 35. In Fig. 4, the keyboard 37 and the mouse 38 are provided as input devices, but the user terminal 5 may also be used as the input device. Furthermore, the monitor 39 is capable of outputting the video of the user terminal 5 via a video cable. A printing device may be placed on the desk 35 .

[0028] In addition, in the work space 4, a lighting fixture 40, motion sensors 41 and 42, a speaker 43, a power outlet (not shown), an access point for wireless communication, etc. are arranged. Here, a human presence sensor 41 is attached to a portion of the ceiling 30A where a user working is likely to be located. The human presence sensor 41 is, for example, an infrared sensor, and detects a heat source that crosses a sensing axis. The heat source here is assumed to be a user. There may be multiple sensing axes. The infrared sensor excludes from its detection targets heat sources that do not move, such as the monitor 39, lighting fixtures 40, and other devices. Note that an infrared sensor that can detect the number and positions of users may also be used.

[0029] A human presence sensor 42 is attached to the wall surface 30E at a position facing the monitor 39. However, the human presence sensor 42 may be disposed on the ceiling 30A or the wall surface 30D. The human presence sensor 42 is, for example, an image sensor (i.e., an image sensor) that captures an image of the inside of the work space 4. The image sensor is a so-called camera. For example, the image captured by the image sensor is processed to detect the number of users staying in the workspace 4. To identify the number of people, for example, a technology for detecting contours that are regarded as people is used. In addition, image sensors sensitive to infrared light can capture clear images even in low-light environments, and the number of people can be identified by analyzing the shape and movement of the subjects.

[0030] The motion sensors 41 and 42 may each be provided in plurality so as to reduce blind spots. Alternatively, an ultrasonic sensor may be used. The ultrasonic sensor may be placed, for example, on the ceiling 30A (see FIG. 2). The distance to the object may be measured by measuring the time it takes for ultrasonic waves emitted from the ultrasonic sensor toward the floor surface to be reflected by the object and return, and the presence or absence of a human may be detected based on the change in distance. The ultrasonic sensor is an example of a human presence sensor. In the case of FIG. 4, the speaker 43 is attached to the wall surface 30E, but it may be attached to any wall surface.

[0031] FIG. 5 is a diagram for explaining an example of the connection between the wiring used for reporting an emergency or disaster and the work space 4. In FIG. 5, the crisis / disaster management server 9 is connected to a monitor 39, lighting fixtures 40, and speakers 43 in the workspace 4 via a communication network 2. The facility-side disaster management server 10 is connected to the monitor 39, lighting fixtures 40, and speakers 43 in the workspace 4 via a communication line 12. In this embodiment, the crisis / disaster management server 9 and the facility-side disaster management server 10 can each control the monitor 39, lighting fixtures 40, and speakers 43 individually.

[0032] FIG. 6 is a diagram for explaining an example of a connection configuration on hardware within the work space 4. In FIG. The connection configuration shown in FIG. In this embodiment, the work space 4 includes, in addition to the lighting fixture 40, human presence sensors 41, 42, and speaker 43 mentioned above, a router 50, a communication interface (communication IF) 51 that terminates the communication network 2, a control device 52 that is used when sharing some of the functions of the reservation management server 6 and the crisis / disaster management server 9, a door drive mechanism 53 that drives the door 32 (see Figure 2) to an open or closed position, an open / close detection sensor 54 that detects the opening and closing of the door 32, a key mechanism 55 that performs locking and unlocking using an electronic key, and a vibrator 56.

[0033] The router 50 also functions as an access point for wireless communication. The control device 52 is a so-called computer, and operates based on firmware or an application program. The control device 52 is an example of a control means that prompts users to evacuate. In the case of FIG. 6, a door drive mechanism 53 is provided, but this is not necessary if the opening and closing of the door 32 is limited to manual operation. The open / close detection sensor 54 may be attached to the door 32 (see FIG. 2), for example. However, the open / close detection sensor 54 may also be attached to the path along which the door 32 moves when opening and closing, or at the open or closed position of the door 32. The vibrator 56 is attached to, for example, the desk 35 (see FIG. 4), the chair 36 (see FIG. 4), or the mouse 38 (see FIG. 4), and attracts the user's attention by vibration.

[0034] <Server configuration> FIG. 7 is a diagram illustrating an example of the hardware configuration of a server that constitutes the management system 1 (see FIG. 1). 7 representatively shows the configuration of the crisis / disaster management server 9. That is, the basic configurations of the reservation management server 6, the billing management server 7, the member management server 8, and the facility-side disaster management server 10 are also similar to the configuration shown in FIG. The crisis / disaster management server 9 has a CPU 61 that provides management functions through the execution of an operation system and application programs, a ROM 62 that is a storage area for storing the operation system and BIOS, and a RAM 63 that is an execution area for programs. These components constitute a so-called computer. These components are also an example of a control means for encouraging users to evacuate. The crisis / disaster management server 9 also has a storage device 64 that stores application programs for realizing the management functions described below and various management data, a communication interface (communication IF) 65 used for communicating with the outside, an input device 66 such as a keyboard, and a display device 67 used to display information. Here, the CPU 61 and various devices are connected via a bus 68 .

[0035] FIG. 8 is a diagram illustrating an example of the software configuration of the crisis / disaster management server 9. The functional configuration shown in FIG. 8 is realized through the execution of a program by the CPU 61 constituting the crisis / disaster management server 9. In this embodiment, the crisis / disaster management server 9 functions as an evacuation requiring event detection unit 71 that detects the occurrence of a crisis or disaster requiring evacuation, an evacuation requiring event notification unit 72 that notifies the occurrence of an event that prompts evacuation in the workspace 4 from which users need to evacuate, an exit detection unit 73 that detects the exit of a user from the workspace 4 that is the subject of the notification, an unlock control unit 74 that forcibly unlocks the electronic lock to enable rescue from outside, and an indicator light control unit 75 that controls the display of the indicator light 34 (see Figure 2) attached to the outer wall of the workspace 4.

[0036] In this embodiment, when the evacuation event detection unit 71 receives information regarding a wide-area crisis or disaster from the disaster prevention communication network 3, or when it receives information regarding a local crisis or disaster where the workspace 4 is located from the facility-side disaster management server 10, it determines the need for evacuation in accordance with predetermined criteria. When the predetermined criteria are satisfied, the evacuation requiring event detection unit 71 detects that an event requiring evacuation has occurred. Information that satisfies the predetermined criteria among information on a wide-area crisis or disaster and information on a local crisis or disaster is an example of an event requiring evacuation.

[0037] The criteria here may vary depending on the type of crisis or disaster. For example, evacuation orders, fires, and the like may be detected as events that unconditionally require evacuation. For example, with regard to earthquakes among natural disasters, the occurrence of an earthquake with a seismic intensity of 4 or more may be detected as an event requiring evacuation. The seismic intensity may be a predicted value. For example, a warning about a natural disaster may be detected as an event requiring evacuation. For example, the criteria may include whether or not to treat a received evacuation advisory, evacuation preparation, or evacuation start notice for elderly people and the like as an event requiring evacuation.

[0038] These standards may vary depending on the location where the workspace 4 is located and the business providing the hourly rental service. For example, different criteria may be used depending on the provider of the reservation service for the workspace 4, or different criteria may be used depending on the business providing the installation location. In addition, different standards may be used for each building in which each work space 4 is installed, or standards may be used based on the floor on which the work space 4 is installed even if the work space 4 is installed in the same building, or different standards may be used based on the location of the work space 4 even if the work space 4 is installed on the same floor, or different standards may be adopted depending on the type of work space 4.

[0039] When the evacuation-requiring event notification unit 72 detects the occurrence of an event requiring evacuation, it controls the devices and user terminals 5 provided in the target workspace 4 to urge users to evacuate. The evacuation-required event notification unit 72 urges evacuation, for example, by controlling the user terminal 5 carried by the user, outputting an image to the monitor 39 installed in the work space 4, controlling the lighting state of the lighting fixtures 40, outputting sound from the speaker 43 installed in the work space 4, etc. Specific examples will be described later. In addition, the evacuation event notification unit 72 also has the function of obtaining the user's exit status from the exit detection unit 73, and changing the content of the notification to the user depending on the elapsed time since the occurrence of an event requiring evacuation was detected.

[0040] The change in the content of the notification is based on the difference in the operation mode managed by the evacuation required event notification unit 72. In this embodiment, the period from the detection of the occurrence of an event requiring evacuation until the passage of a first period (period #1) is managed as a first alarm mode, and the period from the passage of the first period until the passage of a second period (period #2) is managed as a second alarm mode. In this embodiment, the first period is determined in consideration of the time required for exit. The time required for exit is, for example, the time required for putting away documents and a laptop computer used in work. In this embodiment, the first period is set to about one to two minutes. It may be less than one minute or more than two minutes.

[0041] In this embodiment, the second period is determined in consideration of the preliminary time required before requesting rescue, assuming that users may not notice the notification urging evacuation or may notice it late. In this embodiment, the number of media, types of media, combinations of media, and intensity of notification, such as sound, light, image, and vibration, are changed between the first and second alarm modes. Of course, in the second alarm mode, the content is determined so as to convey a more urgent message. In this embodiment, the second period is set to about one minute. Basically, the second period may be shorter than the first period, because if evacuation or exit of the occupants is not detected after the second period has elapsed, there is a high probability that the occupants will need to be rescued. However, the specific values ​​of the first and second periods depend on the management's thinking. The evacuation-requiring event notification unit 72 is provided with a clock for measuring the elapsed time.

[0042] The exit detection unit 73 detects the exit of a user based on output signals from the human sensors 41, 42, the open / close detection sensor 54, etc. Exit here means that there is no user remaining inside the work space 4. In this embodiment, as a primary determination, the opening of the door 32 (see FIG. 2) is treated as an exit of a user. When more accurate detection is required, the output signals of the human sensors 41 and 42 are used in combination. Users whose exit is detected by the exit detection unit 73 are not limited to users who have made reservations on the reservation management server 6 (see FIG. 1). Even if there is only one person who has made a reservation, from an operational standpoint, there is a possibility that an attendant may have entered the room with the person. Also, when there are multiple users, it is not sufficient to detect the exit of some of the users. Therefore, the exit detection unit 73 uses the human sensors 41 and 42 to detect the exit of all users.

[0043] For example, when the user's exit is not detected, the unlock control unit 74 forcibly unlocks the electronic lock to enable rescue from outside. For example, when the user's exit is not detected even after the second period has elapsed, the electronic lock is unlocked by the function of the unlock control unit 74. The indicator light control unit 75 controls the display of the indicator lights 34 (see FIG. 2) attached to the outer wall of the work space 4. 9 is a diagram illustrating an example of control of the indicator light 34 by the indicator light control unit 75 (see FIG. 8). (A) shows an example of control when an unoccupied person is detected during the first alarm mode, (B) shows an example of control when a person is detected during the first alarm mode, (C) shows an example of control when an unoccupied person is detected during the second alarm mode, and (D) shows an example of control when a person is detected during the second alarm mode.

[0044] In this embodiment, when a user is present in the work space 4 (i.e., when there is a person present), the color is displayed in red, and when the user has left the work space (i.e., when there is no person present), the color is displayed in blue. However, the display colors are merely an example, and other color combinations may be used. In addition, in the case of this embodiment, the light continues to be on during the first alarm mode, whereas it flashes during the second alarm mode. The flashing attracts the attention of people in the vicinity. Of course, switching the light on is only an example, and other control may be used. For example, the light may be flashed in the first alarm mode and the second alarm mode, and the flashing cycle in the second alarm mode may be shorter than that in the first alarm mode. Incidentally, before the transition to the alarm mode, the indicator lamp 34 is turned off.

[0045] <Processing operations of the crisis / disaster management server> FIG. 10 is a flowchart illustrating an example of a processing procedure executed by the crisis / disaster management server 9 (see FIG. 1). In FIG. 10, steps are indicated by the symbol S. The processing procedure shown in Fig. 10 is started after the reservation management server 6 has already finished accepting the reservation and the reserved time has arrived. Fig. 10 shows the processing after the electronic lock on the workspace 4 has been unlocked. The crisis / disaster management server 9 detects the entry of users through communication from the reservation management server 6 (step 1). When the number of users who have entered the workspace 4 is detected, the reservation management server 6 also notifies the server 9 of information on the number of users staying in the workspace 4.

[0046] Next, the crisis / disaster management server 9 determines whether or not it has detected the occurrence of an event requiring evacuation before detecting the exit (step 2). The term "exit" here includes not only the case where the user exits after the reserved time has elapsed, but also the case where the user exits temporarily within the reserved time. The process of step 2 is executed by the evacuation-requiring event detection unit 71 (see FIG. 8). As mentioned above, even if an earthquake occurs that is weaker than the standard, it will not be detected as an event requiring evacuation. A negative result is obtained if an exit of an occupant is detected before the occurrence of an event requiring evacuation is detected. If the crisis / disaster management server 9 obtains a negative result in step 2, it ends the process without executing the process described below.

[0047] On the other hand, if the occurrence of an event requiring evacuation is detected while a user is present in the workspace 4, a positive result is obtained. The crisis / disaster management server 9, which obtains a positive result in step 2, sets the management status of the affected workspace 4 to the first alarm mode (step 3). The processing of step 3 is executed by the evacuation required event notification unit 72 (see FIG. 8). The affected workspace 4 is determined based on predetermined rules. The rules here may differ depending on, for example, the type of crisis or disaster, or the facility that is set. The rules here may also differ depending on the business operator providing the hourly rental service. For example, in the case of a fire, only the status of the management of workspaces 4 located in the vicinity of the fire scene is set to the first alarm mode. For example, in the case of an evacuation order due to heavy rain or the like, only the management state of the workspace 4 installed in the area subject to the evacuation order is set to the first alarm mode. The following processing operations are executed only for workspaces 4 whose management status is set to the first alarm mode.

[0048] When the operation mode is set to the first alarm mode, the crisis / disaster management server 9 instructs the output of an alarm (step 4). The alarm is output with contents corresponding to the first alarm mode. The contents to be output are predetermined. For example, text or images instructing evacuation are output to the screen of the user terminal 5 or monitor 39. For example, a sound (alert sound 1) that prompts evacuation is output from the speaker 43. The sound may be an alarm sound or a voice. Also, an alarm sound and a voice may be combined. The process of step 4 is executed by the evacuation-requiring event notification unit 72 (see FIG. 8).

[0049] Next, the crisis / disaster management server 9 determines whether or not the door 32 (see FIG. 2) has been opened within a first period (period #1) (step 5). The process of step 5 is executed by, for example, the evacuation-requiring event notification unit 72 (see FIG. 8). The evacuation-required event notification unit 72 determines whether the door 32 has been opened based on, for example, an output signal of the open / close detection sensor 54 (see FIG. 6). Here, the evacuation event notification unit 72 detects whether the door 32 is opened to a predetermined open position. The predetermined open position is a position that creates at least a space that allows people to enter and exit. This is because even if the door 32 is opened a few centimeters, the user cannot exit the workspace 4.

[0050] The process of step 5 may use the result of detection by the exit detection unit 73 (see FIG. 8). The exit detection unit 73 detects the exit of a user from the working space 4 using, for example, signals output from the human sensors 41, 42 (see FIG. 6). If the exit detection unit 73 detects the exit of a user, a positive result is obtained in step 5. The exit here does not refer to the number of users who have reserved the space, but to the exit of all the actual people estimated to be present in workspace 4. Since it is important that everyone leaves, even if the departure of a user who made a reservation can be detected, if there is only one person in workspace 4, this is not considered an exit in step 5.

[0051] If a positive result is obtained in step 5, the crisis / disaster management server 9 instructs to stop outputting the alarm (step 6). The process of step 6 is executed by the evacuation-requiring event notification unit 72 (see FIG. 8). By executing this process, the alarms that have been output in the work space 4 are stopped. Specifically, the first alarm mode is released. On the other hand, if a negative result is obtained in step 5, the crisis / disaster management server 9 switches the operation mode to the second alarm mode (step 7). The process of step 7 is also executed by the evacuation requiring event notification unit 72 (see FIG. 8). When the operation mode is switched to the second alarm mode, the crisis / disaster management server 9 changes the content of the alarm to that of the second alarm mode. For example, the text and images instructing evacuation displayed on the screen of the user terminal 5 or monitor 39 are changed to content that indicates a greater sense of urgency. For example, the lighting fixture 40 is changed from a lit state to a flashing state. For example, the sound output from the speaker 43 is changed to another sound (notification sound 2).

[0052] Next, the crisis / disaster management server 9 determines whether or not the door 32 (see FIG. 2) has been opened within a second period (period #2) (step 8). The process of step 8 is executed by, for example, the evacuation-requiring event notification unit 72 (see FIG. 8). The content of step 8 is the same as the content of step 5. If a positive result is obtained in step 8, the crisis / disaster management server 9 proceeds to step 6 described above.

[0053] If a negative result is obtained in step 8, the crisis / disaster management server 9 requests confirmation from the facility-side disaster management server 10 (step 9). The process of step 9 is also executed by the evacuation event notification unit 72 (see FIG. 8). This is because if the opening operation of the door 32 (see FIG. 2) is not detected even after the second period (period #2) has elapsed, there is a high probability that a user remains in the workspace 4. When the information of the workspace 4 that needs to be checked is provided to the facility disaster management server 10, rescue operations are started by the facility manager. In particular, when a large number of workspaces 4 are installed within a facility, rescue operations can be efficiently carried out by the facility manager by identifying the information of the workspace 4 that needs rescue.

[0054] <Specific examples of notification> A specific example of the notification will be described below. Example of sound notification 11 is a diagram illustrating an example of controlling speaker 43 to notify the occurrence of an event requiring evacuation. (A) is a diagram illustrating sound output in the first alarm mode, and (B) is a diagram illustrating sound output in the second alarm mode. In FIG. 11, the sound output from the speaker 43 in the first alarm mode is represented as an alarm sound 1, and the sound output from the speaker 43 in the second alarm mode is represented as an alarm sound 2. In the case of FIG. 11, the volume of informative sound 2 is louder than the volume of informative sound 1, which is expressed by the difference in the area of ​​the speech bubble.

[0055] As described above, both the notification sound 1 and the notification sound 2 may be an alarm sound or a voice encouraging evacuation. Moreover, the notification sound 1 may be an alarm sound and the notification sound 2 may be a voice encouraging evacuation. Conversely, the notification sound 1 may be a voice encouraging evacuation and the notification sound 2 may be an alarm sound. Moreover, both the notification sound 1 and the notification sound 2 may be a combination of an alarm sound and a voice. The work space 4 is designed to make it difficult for outside sounds to be heard so that users can concentrate on their work. Also, the work space 4 is designed to make it difficult for sounds to leak outside so that confidentiality can be maintained. Therefore, by outputting the alarm sounds 1 and 2, it is possible to inform users of the occurrence of an event that requires evacuation. The voice to be output is pre-recorded and stored in the storage device 64 as a voice file.

[0056] 12 is a diagram illustrating changes in the output patterns of the alarm sounds 1 and 2. (A) shows an example of the output pattern when the user's exit is not detected, and (B) shows an example of the output pattern when the user's exit is detected. In FIG. 12, the vertical axis represents volume and the horizontal axis represents time. 12, the informative sound 1 for the first period (period #1) is output during a first period T1, while the informative sound 2 for the second period (period #2) is output during a second period T2 that is shorter than the first period T1.

[0057] In the example of Figure 12, the volume of alarm sound 2 output during the second period is made louder than the volume of alarm sound 1 output during the first period, so that even users who do not notice alarm sound 1 are made aware of the need to evacuate. For example, if a user is wearing headphones or earphones and enjoying music, or if the user is deep asleep, the user may not notice the alarm sound 1. In the example of FIG. 12, the second period T2 is set shorter than the first period T1, so that the user can easily feel a sense of urgency or urgency. The range (frequency) and volume of the alarm sounds 1 and 2 may be changed depending on the age or age category of the user. The example in Figure 12 shows an example in which an opening operation of the door 32 (see Figure 2) is detected during the second period and the output of the alarm sound 2 is stopped, but if an opening operation of the door 32 is detected during the first period, the output of the alarm sound 1 is stopped.

[0058] Example of notification by illumination 13A and 13B are diagrams illustrating an example of controlling lighting device 40 (see FIG. 6) to notify the occurrence of an event requiring evacuation. (A) shows an example of a control pattern when exit of a user is not detected, and (B) shows an example of a control pattern when exit of a user is detected. In FIG. 13, the vertical axis represents the amount of light, and the horizontal axis represents time. 13, there is no change in the brightness of lighting device 40 between the period before the occurrence of an event necessitating evacuation and the first period (period #1). On the other hand, the brightness of lighting device 40 is increased in the second period (period #2) compared to the first period. By increasing the brightness around the user, the user is visually notified of the change in the environment. It is known that when the color temperature is low and the illuminance (lux) is high, discomfort increases (the so-called Kruzov effect). Therefore, by increasing the illuminance in the second period more than in the first period, it is possible to psychologically encourage people to leave the workspace 4. In the example of FIG. 13, the light intensity returns to the original level after the opening operation of door 32 (see FIG. 2) is detected during the second period, but lighting device 40 may be turned off after the user leaves.

[0059] 14 is a diagram illustrating another example of controlling lighting device 40 (see FIG. 6) to notify the occurrence of an event requiring evacuation. (A) shows an example of a control pattern in which the color temperature is changed after the start of the second period, (B) shows an example of a control pattern in which the light is blinked after the start of the second period, and (C) shows an example of a control pattern in which the blinking cycle and light intensity are changed between the first and second periods. In FIG. 14, the vertical axis represents the amount of light, and the horizontal axis represents time. In the case of (A), the light intensity of lighting device 40 remains the same both before and after the occurrence of an event requiring evacuation, but after the start of the second period (period #2), color temperature is switched from color temperature 1 to color temperature 2. It is known that even if the illuminance (lux) is the same, if the color temperature is high, discomfort increases (the so-called Kruzov effect). Therefore, by setting color temperature 2 higher than color temperature 1, it is possible to psychologically encourage people to leave workspace 4.

[0060] In the case of (B), the light intensity of lighting device 40 remains the same both before and after the occurrence of an event requiring evacuation. However, in the case of (B), lighting device 40 is controlled to a blinking state after the start of the second period (period #2). By flashing the lighting, the sense of urgency is heightened, and it is possible to psychologically encourage people to leave the workspace 4. In the case of (C), the illumination light is turned on and off at the same time as the first period starts, to visually notify the user of the occurrence of an event requiring evacuation. However, the light intensity of lighting device 40 during the first period remains the same as before the occurrence of the event requiring evacuation. Next, when the second period starts, the blinking cycle is made shorter than in the first period, and the light intensity of lighting device 40 is made greater than in the first period. By increasing the light intensity and shortening the blinking cycle at the same time, the sense of urgency is heightened, making it possible to psychologically encourage people to leave the workspace 4.

[0061] Example of a notification displayed on the screen FIG. 15 is a diagram illustrating an example of notifying the occurrence of an event requiring evacuation by a screen display. In the case of FIG. 15, a message instructing evacuation is displayed on both the user terminal 5 carried by the user and the monitor 39 placed in the work space 4 (see FIG. 4). In this embodiment, since the user holds the smartphone over the door to release the electronic lock, the user has the smartphone at hand. Therefore, it is possible to urge the user to leave by displaying a message urging the user to evacuate on the screen of the smartphone. In the example of Fig. 15, the message "A fire has broken out. Please evacuate" is displayed, but the message can be anything. Also, figures, images, symbols, etc. encouraging evacuation may be displayed on the screen. Furthermore, text and images may be displayed in combination, or text and images may be displayed alternately. Additionally, evacuation shelters may be displayed on the screen. The push display on the screen is realized as a function of an application program when a notification of the occurrence of an event requiring evacuation is received.

[0062] Example of vibration alert FIG. 16 is a diagram illustrating an example in which a vibrator is activated to notify the occurrence of an event requiring evacuation. In the case of FIG. 16, a state is displayed in which vibration control is performed on both the user terminal 5 carried by the user and the chair 36 placed in the work space 4 (see FIG. 4). The vibration of the user terminal 5 is premised on the fact that the user terminal 5 is provided with a vibrator. The vibration of the user terminal 5 is realized as a function of an application program when a notification of the occurrence of an event requiring evacuation is received. 16, the vibrator is provided on chair 36, but it may also be provided on desk 35, keyboard 37, mouse 38, etc. By combining vibrations, it becomes possible to make the user aware of the occurrence of an event that requires evacuation even when the user is wearing headphones or while sleeping.

[0063] Example combinations Here, we will explain a method of notifying the occurrence of an event requiring evacuation by combining sound, lighting, screen display, vibration, etc. FIG. 17 is a diagram for explaining an example of a combination for notifying a user of an event requiring evacuation through actions on the user's senses of sight, hearing, touch, pressure, and force. Devices that affect the sense of hearing are collectively referred to as audio output devices. A specific example of an audio output device is a speaker 43 (see FIG. 4). The devices used for vision are expressed as an image output device and a lighting output device. Specific examples of the image output device are the monitor 39 (see FIG. 4) and the user terminal 5 (see FIG. 1), and a specific example of the lighting output device is the lighting fixture 40 (see FIG. 4). Devices that act on the sense of touch, pressure, and force are referred to as haptic output devices and vibration output devices. A haptic output device is a device that simulates the sensation of touching an object and the force that occurs when touching an object. For example, a vibrator or ultrasound is used to generate the sense of touch or force. A specific example of a vibration output device is a vibrator.

[0064] In FIG. 17, the notification techniques in the first warning mode are represented as A1, B1, C1, and D1, and the notification techniques in the second warning mode are represented as A2, B2, C2, and D2. For example, in A1, the siren and the voice instructing evacuation are both output at a medium volume, and in A2, the siren and the voice instructing evacuation are both output at the maximum volume. Note that in A2, the intermittent interval of the sound is different from that in the first alarm mode. For example, the contents of B1 and B2 are the same, and a screen instructing evacuation is displayed on the smartphone and monitor 39. For example, C1 has no change in lighting, whereas C2 has the lighting flicker and change in color temperature. For example, D1 does not activate the corresponding output device or activates the vibration mode of the smartphone, and D2 forcibly activates the vibration mode of the smartphone and switches the chair 36, mouse 38, and desk 35 to vibration mode.

[0065] In the first alarm mode, it is possible to alert by only A1 (sound), by a combination of A1 (sound) and B1 (screen), or by a combination of A1 (sound), B1 (screen) and D1 (tactile sensation). In addition, in the second alarm mode, it is possible to alert by A2 (sound) only, by a combination of A2 (sound) and B2 (screen), by a combination of A1 (sound) and C2 (light), by a combination of A1 (sound), C2 (light) and D2 (tactile sensation), or by a combination of A2 (sound), B2 (screen), C2 (light) and D2 (tactile sensation). As shown in FIG. 17, it is also possible to combine the notification for the first alarm mode and the notification for the second alarm mode.

[0066] <Rescue support for users> The above example assumes that a user notices an alarm urging them to evacuate and exits, but it is possible that for some reason the user may be delayed in leaving workspace 4 (see Figure 1) and may need help from someone other than the user. 18 is a diagram illustrating a function that allows entry from outside the workspace 4. (A) shows an example in which the electronic lock is released simultaneously with the detection of an event requiring evacuation, (B) shows an example in which the electronic lock is released when the user's exit is not detected even after a predetermined time T11 has elapsed since the start of the first period (period #1), and (C) shows an example in which the electronic lock is released when the user's exit is not detected even after the first period (period #1) has elapsed.

[0067] In the case of (A), the electronic lock is unlocked whether the user is unaware of the alarm or has heard the alarm and is preparing to leave. In the case of (A), the lock is unlocked almost simultaneously with the alarm being sent to the user using the workspace 4, so that an exit route from the workspace 4 can be secured early, and rescue by a third party can also be facilitated early. On the other hand, it is assumed that some users do not want a third party to be able to enter the room immediately after an event requiring evacuation is detected. For example, if the entrance is located in a blind spot, such as behind the user, it is difficult to notice a third party entering the room. Therefore, in the case of (B), in order to ensure time for the user to prepare for exit while enabling early rescue, if exit is not detected within a predetermined time T11 from the start of the first period, the unlocking control unit 74 (see Figure 8) is allowed to unlock the door. On the other hand, the example of (C) is an example in which the unlocking control unit 74 synchronizes the unlocking with the second period (period #2). This is because there remains a possibility of the intruder leaving the door on his / her own during the first period.

[0068] <Other embodiments> Although the embodiment of the present invention has been described above, the technical scope of the present invention is not limited to the scope described in the above embodiment. It is clear from the claims that various modifications and improvements to the above embodiment are also included in the technical scope of the present invention.

[0069] In the above-described embodiment, the monitor 39 (see FIG. 4), lighting fixtures 40 (see FIG. 4), speakers 43 (see FIG. 4), etc. provided in the workspace 4 are connected to both the crisis / disaster management server 9 (see FIG. 1) and the facility-side disaster management server 10 (see FIG. 5), but they may be connected to only one of them. 19 is a diagram for explaining an example in which the monitor 39, lighting fixtures 40, speakers 43, etc. provided in the work space 4 are connected only to the crisis / disaster management server 9. In this case, the facility-side disaster management server 10 outputs an alarm sound notifying the necessity of evacuation and a voice guiding evacuation through a speaker 43A arranged in the facility.

[0070] In the connection shown in FIG. 19, even if an alarm sound or the like notifying an outbreak of a fire or the like within the facility is output from the speaker 43A, the external sound is transmitted to the inside of the work space 4 attenuated levels. However, in the case of FIG. 19, it is possible for the linked crisis / disaster management server 9 to notify the workspace 4 of the occurrence of a fire or the like within the facility. The monitor 39, lighting fixtures 40, speakers 43, etc. provided in the work space 4 may be connected only to the facility-side disaster management server 10 via a communication line 12 that has excellent fire resistance and heat resistance.

[0071] In the above embodiment, the door 32 (see FIG. 4) is disposed diagonally to the rear right with respect to the user working, but the location of the door 32 is not limited to this. 20 is a diagram illustrating another configuration example of the work space 4. (A) is a diagram showing the inside of the work space 4 with the ceiling 30A removed, and (B) is a diagram showing the inside of the work space 4 with the wall surface 30C in a position where a user working is viewed from the side removed. In the case of Fig. 20, the door 32 is provided on the wall surface 30E behind the user who is working. Also, the door 32 in Fig. 20 is an example of a hinged door. Door 32 in Fig. 20 also has member 32B that has been processed with consideration for confidentiality and crime prevention. In the case of Fig. 20, member 32B is placed only on the foot side so that the screen of monitor 39 cannot be seen from outside. For example, member 32B is placed in a position where the screen of monitor 39 is in a blind spot due to the backrest of chair 36 or a seated user.

[0072] Fig. 21 is a diagram illustrating another configuration example of the work space 4. In the work space 4 shown in Fig. 21, similar to the work space 4 shown in Fig. 20, a hinged door 32 is attached to the wall surface 30E behind the user who is working. 21 is made of an opaque material. Meanwhile, a semi-transparent material 30C1 is fitted into the wall surface 30C that faces the side of the user working. Like the member 32B (see FIG. 2), the member 30C1 here is processed with consideration given to secrecy and crime prevention.

[0073] In the above-described embodiment, the function of notifying users of an event requiring evacuation is executed by the crisis / disaster management server 9 (see FIG. 1 ), but it may also be executed by the facility's disaster management server 10 or the workspace 4. For example, when a function of notifying users of an event requiring evacuation in the workspace 4 is executed, the function is provided by the control device 52 (see FIG. 6).

[0074] In the above-described embodiment, an example was described in which a ceiling 30A (see Figure 2) was provided in the work space 4 (see Figure 1), but the ceiling 30A does not have to be provided, or the ceiling 30A may be provided in only a portion of the work space 4. For example, it may be a private room in an internet cafe surrounded by a partition wall and a door, or a private study room. In the above-described embodiment, incidental equipment stipulated by the Fire Service Act may be installed in the work space 4, and the above-described speaker 43 (see FIG. 4) may be shared with the incidental equipment.

[0075] In the above embodiment, an example has been described in which the work space 4 (see FIG. 1) is installed in a predetermined location, whether outdoors or indoors, but the work space 4 may be a mobile space. An example of a mobile space is a vehicle. An example of a vehicle is an automobile. For example, if an earthquake with a large seismic intensity is reported while driving, there may be a situation where you should park at the side of the road and wait for the shaking to subside, and then get out of the car. For example, even if a fire or accident occurs inside a tunnel, or if a road is closed, accurate information will be sent to each driver, allowing them to receive the information necessary to ensure safety and evacuate.

[0076] When the functions of the above-described embodiment are applied to a vehicle, it is expected that damage can be reduced by sending alerts to ensure safety via the car navigation system installed in the vehicle or a smartphone carried by the user. In this case, the vehicle corresponds to the work space 4, and the car navigation system corresponds to the monitor 39 (see FIG. 4) and the speaker 43 (see FIG. 4) installed in the work space 4. Also, the seat corresponds to the chair 36 (see FIG. 4). [Explanation of symbols]
