Description

  The present invention relates to a private room management system for managing various situations such as the entry / exit of a person into / from a private room, the presence / absence and situation of a person in the private room, and the open / closed state of a door (including a sliding door) of the private room, and in particular In various private rooms where it is difficult to check the internal usage by opening doors and curtains, such as toilet booths of toilets where a large number of unspecified people enter and exit, such as toilet booths in department stores, fitting rooms in department stores, and toilets in restaurants The present invention relates to a private room management system suitable for management.

  The toilets of department stores, service areas, public facilities (for example, schools, sports centers) and the like are provided with a plurality of toilet booths, and facility users can freely use the available toilet booths. Some toilet booths have doors that are normally closed (normally closed doors), so it may not be possible to determine whether the door is in use or is empty unless the door is opened. Therefore, in order to find an empty toilet booth, it is necessary to check by knocking or opening the doors of the toilet booth one by one. However, it is uncomfortable to rattle the locked door from the outside when it is in use, and the door is inadvertently opened if you forget to lock it.

  In addition, in recent years, accidents have occurred where an elderly person falls in a private room such as a toilet booth or bathroom, and a suspicious person lurks in a toilet booth at a department store until the closing time, and after the store closes, crimes that damage the store or steal money. The proposal of the solution is desired.

  Conventionally, as a system for managing private rooms, LED lamps etc. have been installed outside the doors of individual toilet booths so that the usage status of toilet booths can be seen from the outside, and people staying in the toilet booth Systems (Patent Documents 1 to 4) have been proposed that can notify the outside of an abnormality when the time is too long. The system of Patent Document 1 is provided with a human sensor and a timing device, the system of Patent Document 2 is provided with a sensor and a timer for detecting locking of the door, and Patent Documents 3 and 4 are human sensors and a door opening / closing sensor. It is equipped with.

  In a normally closed door type toilet, it is necessary to check whether or not the toilet can be used by opening the door. Even if it is in a usable state, if the toilet is dirty, or if you want to use the Western style, it is a Japanese style room that does not meet the user's wishes. Will find a private room. However, since the human sensor installed in the private room detects the movement of the person, it usually detects not only the movement of the person in the private room but also the movement of the person near the entrance. For this reason, even if the door is opened but the door is closed immediately, the movement of the person near the entrance (outside the private room) is detected and the display lamp is turned on. is there.

  Some recent Western-style toilets have a function of automatically closing the toilet seat and lid when the toilet seat and lid remain open for a certain period of time. In a toilet in which such a toilet is installed, the motion sensor recognizes the movement of the toilet seat and the lid as the movement of the person, and the display lamp may be lit even though no person is present.

  Such a malfunction is inconvenient because it indicates that a private room that should originally be usable cannot be used. A similar problem can occur in private rooms other than toilets.

  The problem to be solved by the present invention is that the above-mentioned malfunction does not occur, and it is possible to correctly display (notify) the state of use and vacancy in the private room, eliminating the inconvenience due to long stay in the private room. An object of the present invention is to provide a private room management system that can promptly notify the outside of an abnormal state such as a person falling down in a private room.

  A private room management system according to the present invention is a private room management system capable of managing the use situation of a private room and the indoor situation of a private room, and includes a terminal installed in the private room, and the terminal includes at least a person in the private room. A human sensor for detecting movement, a door sensor for detecting the opening and closing of the door of the private room, a display unit for displaying the usage status and the indoor situation of the private room to the outside, and a control means, the display unit comprising: When the door is opened and the motion sensor detects the movement of the person, it is temporarily lit, and the control means passes a predetermined time (first time) after the door is closed. Until the signal transmitted from the human sensor is canceled, the display unit switches from temporary lighting to permanent lighting when the human sensor detects a movement of the person after the first time has elapsed. .

  In the private room management system, the display unit is turned off when the human sensor does not detect a human movement within a predetermined time (second time) set in advance after the first time has elapsed. It can also be.

  In the private room management system, a person is required in the private room if the door sensor does not detect the opening of the door even after a predetermined time (third time) has elapsed after the display section is fully lit. It is also possible to display on the display unit a long-stay indicator that informs that the user has stayed for a long time (abnormally long time).

  In the private room management system, even after a predetermined time (fourth time) elapses after the human sensor detects the movement of the person after the display unit switches to the main lighting, If the sensor does not detect the movement of a person, an alarm display for notifying that an abnormality has occurred in the private room can be displayed on the display unit.

  In the private room management system, even if a predetermined time (fifth time) elapses after the door of the private room is opened, a person leaves the private room and the door is closed again, When the sensor does not detect the movement of the person, the control means cancels the signal from the human sensor until the door sensor next detects the opening of the door after the fifth time has elapsed. Even if the toilet seat or lid automatically closes in an empty private room after leaving, the movement is not detected and displayed in the same way as a person's movement, and there is no person in the private room. Nevertheless, it is possible to prevent erroneous display that is displayed as in use.

  In the private room management system, a terminal installed in the private room is connected to a parent device via a network, and the parent device is connected to a private room in which the terminal is installed based on a signal transmitted from the terminal. You may enable it to manage a use condition and a room condition.

  In the private room management system, the master unit may be connected to one or two or more external devices via a network, and the use status and the indoor status of the private room managed by the master unit may be browsed by the external device.

The private room management system of the present invention has the following effects.
(1) Since the display unit temporarily lights up when the door of the private room is opened and the motion sensor detects the movement of the person (approximately the same timing as opening the door), the person opens the door and enters the private room. Even if the person is lurking in the private room without closing the door, it is possible to notify the outside that a person is lurking in the private room. For this reason, it is possible to prevent a crime in which a suspicious person who has been lurking in the private room until the closing time leaves the private room after the closing of the shop and the inside of the shop is damaged or money is stolen. Moreover, since the temporary lighting is performed even when the door is opened for cleaning the private room, it is possible to avoid waste of the user going to the private room that cannot be used during cleaning.
(2) After the temporary lighting, if the second sensor has passed without the human sensor detecting the movement of the person, if the temporary lighting display is turned off, the door is opened but the room does not enter Can prevent a malfunction in which the display unit is turned off and a message indicating that the display unit is in use even though there are no people in the private room is displayed.
(3) When the third time has elapsed without the door sensor detecting the opening of the door, if a long-time stay display is displayed on the display unit, an inappropriate long-time user exit is encouraged. The private room can be used effectively because it can be used by other users. In addition, when the long stay indicator is displayed, when a suspicious person is lurking, the fact can be notified to the outside and the user can be prompted to leave.
(4) If the human sensor does not detect the movement of the person in the private room within the fourth time, if the alarm is displayed on the display unit, the person in the private room will fall down or worse. This is immediately notified to the outside, and can save lives.
(5) If the signal from the human sensor is canceled after the fifth time elapses until the door is opened next, the toilet seat and the lid are opened in the empty private room after leaving. Even if is automatically closed, the movement is not detected as a human movement and displayed on the display unit. For this reason, it is possible to prevent erroneous display that is displayed as being used even though there is no person in the private room. On the other hand, since the signal from the human sensor is not canceled until the fifth time elapses, if the next user enters the private room immediately after the previous user leaves, the display unit is displayed as a new entry. Is temporarily lit, so that the exit and new entry are clearly discriminated and the usage status of the private room is correctly displayed (notified).

(Embodiment of private room management system)
An example of an embodiment of the private room management system of the present invention will be described with reference to the drawings. As an example, the private room management system shown in FIG. 1 is an example in the case of managing a plurality of toilet booths A installed in a toilet T in a parking area. The toilet booth A has a type in which the door B (FIGS. 2B and 2C) is normally closed when not in use (a normally closed door type toilet booth) and a type in which the door B is always open. (Normally open toilet toilet booth) is described here, but the former (normally closed toilet toilet booth) will be described as an example.

[Outline of private room management system]
FIG. 1 shows an outline of the private room management system of the present invention. As shown in FIG. 1, a plurality of toilet booths A are installed in the toilet T in the parking area, and each terminal 1 for managing the status of the toilet booth A is provided in each toilet booth A. ing. Each terminal 1 can communicate with the parent device 2 in a wired or wireless manner, and the parent device 2 can centrally manage information of all the terminal devices 1 (all toilet booths A). The information collected in the master unit 2 is displayed on the central display 3 or can be browsed by the external device 4. Each terminal 1 is assigned a unique address so that it can communicate with the parent device 2 individually. As the communication method, various existing communication methods including polling communication can be used. Communication between the terminal 1 and the base unit 2 will be described later.

[Terminal]
As shown in FIGS. 2A to 2C and FIG. 3, the terminal 1 opens and closes the human sensor 11 that detects the movement of a person in the toilet booth A and the door B of the toilet booth A. A door sensor 12 to be detected, a display unit 13 for displaying the usage status in the toilet booth A, etc., and a control means (computer: microcomputer) 14 for performing signal processing from both sensors 11 and 12 and other signal processing I have.

  As shown in FIGS. 2A to 2C, the human sensor 11 is located inside the toilet booth A so that the movement of the person entering the toilet booth A can be detected, and the door sensor 12 includes the door B and the door B. On the frame (upper frame) C above, the display unit 13 at a position (outer wall of the toilet booth A) visible from the outside of the toilet booth A, and the control means 14 together with the transmission / reception unit 15 for transmitting and receiving signals, etc. It can be provided inside A or outside thereof. The terminal 1 is operated by a power source 16 (FIG. 3) such as a dry battery.

[Human Sensor]
The human sensor 11 detects the movement of a person in the toilet booth A. When a person moves within the detection range, the movement sensor 11 detects the movement and transmits a signal to the transmission / reception unit 15. . Various sensors can be used as the human sensor 11, but in this embodiment, a passive infrared detector (passive sensor) is used. A passive sensor continuously outputs a detection signal for a few seconds (usually about 2 seconds) when a person is detected. While a person is moving (while the human sensor 11 is detecting a person) Repeat signal output for about 2 seconds. A passive sensor detects a change in the amount of heat rays emitted from a person, and does not recognize that it is a person, but in this application, it detects a change in the amount of heat rays emitted from a person. Is referred to as a human sensor 11. Further, for convenience of explanation, in the present application, the state where the human sensor 11 detects a person is expressed as the human sensor being ON, and the state where the human sensor is not detecting a person is OFF. It expresses that it is.

[Door sensor]
The door sensor 12 detects opening / closing of the door B of the toilet booth A. In this embodiment, an existing magnetic sensor is used as the door sensor 12. 2A to 2C, the magnet 12a of the door sensor 12 is attached to the upper surface of the door B of the toilet booth A, and the sensor portion 12b of the door sensor 12 is attached to the upper frame C of the door B. The opening and closing of B can be detected. The door sensor 12 may be other than this, and for example, a reed switch, a three-axis digital compass, a lock sensor that operates by opening and closing the lock, or the like can be substituted. For convenience of explanation, in the present application, the state in which the door sensor 12 detects that the door B is closed is expressed as the door sensor 12 being ON, and the door sensor 12 indicates that the door B is open. The detected state is expressed as the door sensor 12 being OFF.

  In this embodiment, the control circuit controls the first to fifth times shown in FIG. 4 (time setting, detection of elapsed time, etc.). The following first to fifth times are merely examples, and are not limited to these times.

[First time]
In the first time, the door sensor 12 indicates that the door B of the toilet booth A in the standby state (the state where there is no person inside and the door B is closed) is opened and the door B is closed again. Is a predetermined time after detection, and is a time for the control means 14 to cancel the signal from the human sensor 11. The first time is set in advance. For example, when the first time is set to 2 seconds, even if the human sensor 11 detects the movement of the person for 2 seconds after the door B is closed, the detection signal is canceled by the control means 14. , It is processed as not detected. The first time can be set arbitrarily and is preferably about 1 to 5 seconds. In this embodiment, when the human sensor 11 detects the movement of the person after the first time has elapsed, the temporarily lit display unit 13 is switched to the main lighting. In the present application, the state in which the detection signal is canceled in the control unit 14 is expressed as a canceled state, and the normal processing is performed without canceling the detection signal.

[Second time]
The second time is a predetermined time after the first time has elapsed, and is a time for determining the timing for turning off the temporarily lit display unit 13. Similar to the first time, the second time is set in advance. For example, when the second time is set to 2 seconds, if the human sensor 11 does not detect a person's movement during the 2 seconds, the temporarily lit display unit 13 is turned off. The second time can be arbitrarily set, but is preferably about 1 second to 5 seconds. The display unit 13 that is temporarily lit is switched to the main lighting when the human sensor 11 detects the movement of the person after the first time has elapsed. When the movement is detected, the lighting may be switched to the main lighting. In this case, the second time is a time for selecting whether to turn off the temporarily lit indicator lamp 13 or switch to the main lighting.

[Third time]
The third time is a predetermined time after the display unit 13 switches to the main lighting, and is a time for determining whether or not the continuous use time of the toilet booth A is long. As with other times, the third time is set in advance. For example, if the third time is set to 15 minutes, whether or not the human sensor 11 detects a person within that time, whether or not 15 minutes have elapsed since the display unit 13 switched to the main lighting, A display indicating that the usage time has been extended for a long time (long stay display) is displayed on the display unit 13. The third time can be arbitrarily set, but is preferably about 10 to 20 minutes, and at most 30 minutes or less.

[Fourth time]
The fourth time is a predetermined time after the motion sensor 11 no longer detects the movement of the person in the toilet booth A after the main lighting of the display unit 13, and the movement of the user of the toilet booth A is It is a time for checking the time of stop. Similar to other times, the fourth time is set in advance. For example, if the fourth time is set to 5 minutes, the movement of the person is not detected in 5 minutes after the motion sensor 11 stops detecting the movement of the person (after the last movement of the person is detected). When there is no such person, there is a possibility that the person has fallen (the condition is getting worse), and a display (alarm display) to that effect is displayed on the display unit 13. The fourth time can be arbitrarily set, but is preferably about 5 to 10 minutes, and preferably at most 20 minutes.

[5th time]
The fifth time is a predetermined time after the door B of the toilet booth A is opened, the person leaves the toilet booth A, and the door B is closed again, and whether or not the signal from the human sensor 11 is cancelled. It is time to judge. Like the other times, the fifth time is set in advance. For example, when the fifth time is set to 15 seconds, the human sensor 11 is normally operated for 15 seconds after leaving the toilet booth A, and when the 15 seconds have elapsed, the detection signal of the human sensor 11 is canceled. (Changes to the canceled state). The fifth time can be set arbitrarily, but it is about 5 to 20 seconds, but the toilet seat and lid in the toilet booth A automatically closes at the longest (it depends on the toilet seat, but as an example 90 seconds later).

[Display section]
The display unit 13 informs a person outside the toilet booth A whether or not the toilet booth A is in use, and when the staying time in the toilet booth A is long, This is to notify that, or when there is no movement in the toilet booth A for a certain period of time, there is a possibility that an abnormality has occurred inside. In this embodiment, LED illumination is used as the display unit 13, and the LED illumination is turned on when in use, and the LED is turned off when the display is empty. In addition, when displaying that it is staying for a long time, the LED lighting blinks at a predetermined rhythm (assumed to be “rhythm A”), indicating that there may be an abnormality inside. When displaying, the LED illumination blinks at a rhythm different from rhythm A (assumed to be “rhythm B”).

  The display unit 13 may be displayed in any other way as long as it can inform the person outside of the situation of the toilet booth A. For example, when the toilet booth A is empty, “unused” or “vacant” May be displayed, and when in use, the characters “in use” or “in-room” may be displayed. In addition, a portion for displaying whether or not the device is in use, a portion for displaying a long-time stay, and a portion for displaying an alarm may be provided separately so that they are selectively lit according to the situation.

[Base unit]
The master unit 2 receives the information (private room information signal) on the toilet booth A transmitted from the terminal 1, and uses all the toilet booths A installed in the toilet T in the parking area (whether it is empty or not). It is used in a unified manner to control whether it is in use (same in the present application) or / and indoor conditions (whether a long-time stay display or warning display is performed. The master unit 2 may be any device that can at least receive signals transmitted from the terminal 1, process received signals, and transmit processed information to the outside. A personal computer in which (application) is incorporated can be used. For example, a signal related to the status of the toilet booth A is transmitted to the master unit 2 from the terminal 1 of each toilet booth A, so that the same display as the display unit 13 of the terminal 1 is displayed. can do. In this embodiment, the master unit 2 is installed in an administrator room (not shown) that manages the toilet T in the parking area, and processing information in the master unit 2 can be confirmed on a display connected to the master unit 2. It is like that. What is necessary is just to determine the installation place of the main | base station 2 according to the number, the use, etc. of the toilet booth A to manage. The base unit 2 is not always necessary, and a repeater (not shown) for relaying the terminal 1 and the external device 4 can be used.

[Centralized display]
The centralized display 3 displays the usage status and indoor status of all toilet booths A in a lump. As an example, the concentrated display body 3 shown in FIG. 5 is a model of the toilet T in the actual parking area, and is linked with the lighting / extinguishing of the display unit 13 of the toilet booth A. The central display 3 can confirm at a glance whether the toilet seat is a Japanese style or a Western style in addition to the usage status and indoor conditions of all toilet booths A installed in the parking area.

  Specifically, when a certain toilet booth A is in use (the display unit 13 of the toilet booth A is lit), the corresponding part of the central display 3 is lit, and the toilet booth A is empty. When the state is reached (the display unit 13 of the toilet booth A is turned off), the corresponding part of the central display 3 is turned off. In this embodiment, the case where the centralized display body 3 is provided on the wall surface outside the entrance of the toilet T is taken as an example. However, the centralized display body 3 is not a wall surface outside the entrance such as the wall surface inside the entrance of the toilet T. It can also be provided at a place. The central display 3 can be linked directly to the terminal 1 and can also be linked to the base unit 2.

[External device]
In this embodiment, the information processed by the parent device 2 can be confirmed by the external device 4. As the external device 4, for example, a mobile phone, a smartphone, a tablet terminal, a notebook PC, a dedicated machine for the private room management system of the present invention, and other various terminals capable of network communication can be used. When confirming information with the external device 4, for example, an application relating to the private room management system can be downloaded, and the status of the toilet T can be confirmed through the application. The display method in the application can be appropriately designed according to the external device 4, but in any case, it is preferable that at least the same information as that of the centralized display 3 can be confirmed.

[Operation of terminal and base unit]
An operation between the terminal 1 and the base unit 2 will be described. The signal processed by the terminal 1 is transmitted to the parent device 2 so that the usage status and the indoor situation of the toilet booth A where the terminal 1 is installed can be confirmed by the parent device 2. When there are a plurality of toilet booths A as in the parking area, a detection signal from the terminal 1 installed in each toilet booth A is transmitted to the master unit 2, and all the toilet booths in which the terminals 1 are installed The use status and indoor status of A can be grasped centrally by the master unit 2. When the main booth 2 confirms the toilet booth A for which the stay display or warning is displayed for a long time, a manager or a worker can go to the toilet booth A and take necessary measures promptly.

  Communication can also be performed between the terminal 1 and the parent device 2 in order to check whether the terminal 1 is operating normally. Equipment such as the human sensor 11, door sensor 12, display unit 13, control unit 14, transmission / reception unit 15, power supply 16, etc. of the terminal 1 does not always operate normally, and may fail or run out of battery. is there. Therefore, in order to detect these abnormalities, a call signal is periodically sent from the base unit 2 to the terminal 1, and a response signal from the called terminal 1 is received so that the abnormality of the equipment can be detected. It is.

  The base unit 2 detects the battery voltage (remaining battery level) of the terminal 1 from the level of the received signal level from the terminal 1 by the program in the control means 14 or the terminal 1 based on the current received from the terminal 1 A failure of the display unit 13 on the side can be confirmed. When the remaining battery level, display unit 13 failure, toilet booth A abnormality, etc. are detected, an administrator or worker goes to the toilet booth A where the terminal 1 is installed, and the battery is quickly replaced. And repair of equipment and parts replacement.

(Other embodiments of the private room management system)
In the above embodiment, the display unit 13 is temporarily lit when the door B is opened and the human sensor 11 detects the movement of the person (when the human sensor is turned on). Regardless of whether or not 11 detects the movement of a person, when the door sensor 12 detects the opening of the door B (when the door sensor 12 is turned off), the display unit 13 is temporarily lit. You can also. In addition, when the door sensor 12 detects that the door B is opened and the human sensor 11 detects a human movement (when the door sensor 12 is OFF and the human sensor 11 is ON). When the movement of the person is detected by the human sensor 11 and the door B is detected by the door sensor 12 (when both the human sensor 11 and the door sensor 12 are turned on), The display unit 13 may be temporarily lit.

  In the embodiment, the case where the toilet booth A installed in the parking area is managed is taken as an example. However, the private room management system of the present invention includes a stadium, an exhibition hall, a restaurant, a public facility, an accommodation facility in addition to the parking area. It can be used to manage toilets T installed in facilities used by an unspecified number of people, such as capsule hotels, hot spring facilities, pool facilities, and sports gyms. For example, when managing the toilet booth A of the toilet T on many floors like a department store or a high-rise building, the terminal 1 is installed in the toilet booth A on each floor, and information on all the toilet booths A is stored. The centralized display 3 can be used for centralized management. In this case, it is preferable that the usage status of all or several floors of the toilet booth A can be displayed on one centralized display 3. By displaying the usage status of toilet booths A on two or more floors on the central display 3 on one floor, you can list the usage status of toilet booths A on each floor and use the toilet booth A on an empty floor. There is a merit that it is easy.

  In the above embodiment, the toilet booth A with a normally closed door is taken as an example, but the basic operation is the same when the toilet booth A is a toilet booth A with a normally open door. In the case of the normally open door toilet booth A, in the standby state, both the human sensor 11 and the door sensor 12 are OFF, and the display unit 13 is turned off. Other basic operations (cancellation after door B is closed, switching from temporary lighting to permanent lighting, switching from temporary lighting to extinguishing, display when staying for a long time, when a person does not move for a certain period of time The alarm display etc.) is also the same for the toilet booth A with a normally closed door. The door B in the present application includes a sliding door that slides in the horizontal direction in addition to a door that rotates to the front side and the individual room side.

(Operation of private room management system)
The operation of the private room management system shown in FIG. 1 will be described based on the time chart of FIG.

[Standby]
When the toilet booth A is in a standby state, the human sensor 11 is OFF, the door sensor 12 is ON, and the display unit 13 is off. In the standby state, the detection signal of the human sensor 11 is canceled by the control means 14 (cancellation state), and this state is switched to normal operation as soon as the door B is opened (the detection signal is normal by the control means 14). It is processed).

[Temporary lighting of the display]
When the user opens the door B, the door sensor 12 detects that the door B is opened, and the door sensor 12 is turned off. Further, when the door B is opened, a person who enters the human sensor 11 is detected at the same time or substantially simultaneously, and the human sensor 11 is turned on. When the door B is opened and the human sensor 11 detects a person, the display unit 13 is temporarily turned on (a message indicating that it is in use is temporarily displayed).

[Main display on or off]
When a person enters the toilet booth A and the door B is closed, the door sensor 12 detects that the door B is closed, and the door sensor 12 is turned on. The door sensor 12 is kept on until the door B is opened next time. When the door B is closed (when the door sensor 12 detects that the door B is closed), the control means 14 is switched to the cancel state, and the detection signal from the human sensor 11 is cancelled. The cancel state is maintained until a first time set in advance (for example, 2 seconds after the door B is closed) elapses.

  When the first time elapses, the control unit 14 switches from the cancel state to the normal operation, and the detection signal from the human sensor 11 is processed in the control unit 14 as usual. The human sensor 11 that has been switched to the normal operation continues to operate normally until a certain time (fifth time to be described later) elapses after the door B is opened.

  When the human sensor 11 detects the movement of the person after the first time has elapsed, the display unit 13 is switched to the main lighting. When the human sensor 11 does not detect the movement of the person within the second time (the X portion in FIG. 6) after the first time has elapsed, the display portion 13 that has been temporarily lit is turned off.

  When the door B is opened and the toilet booth A is entered, it is normal to perform operations such as removing the belt and lowering the trousers. When the booth A is not entered, since the human sensor 11 does not detect a person after the door B is closed, the display unit 13 is turned off and the person is not in the toilet booth A. Nevertheless, there is no problem that the display unit 13 continues to be lit. In addition, after the display part 13 is turned off, it returns to a standby state.

  The reason for setting the cancellation time (first time) in the present invention is to avoid the following situation. For example, it is assumed that a person who tried to use the toilet booth A opened the door B but closed the door B without entering the inside. In this case, when the human sensor 11 detects a person between the time when the door B is opened and closed, the detection signal from the human sensor 11 is continuously output for 2 seconds. Therefore, if the door B of the toilet booth A is closed 1 second after the detection by the human sensor 11, the human sensor 11 is in an ON state for 1 second (2 seconds in total) before and after the door B is closed. . In this case, if the display unit 13 is set to be switched on when the human sensor 11 is turned on after the door sensor 12 is turned on, whether or not there is a person inside, The display unit 13 is switched to the main lighting. That is, when the cancel time is not set, there is a possibility that the display unit 13 continues to be lit even though there is no person inside. However, in the present invention, the above-described cancel time is set. Thus, the above problem can be avoided.

[Long stay display on the display]
The door sensor 12 detects the opening of the door B until the preset third time (for example, 15 minutes) elapses (the Y portion in FIG. 6) after the display unit 13 switches to the main lighting. If not (when the door sensor 12 is not turned ON within the third time), the display unit 13 switches from the main lighting to the long stay display. The long stay display continues until the door B is opened next time.

[Alarm display on display section]
After the display unit 13 switches to the main lighting, the fourth time after the human sensor 11 detects the last human movement (for example, after the human sensor 11 detects the last human movement). Is displayed when the human sensor 11 does not detect a person (when the human sensor 11 has not been turned on within that time) until 5 minutes elapse (Z portion in FIG. 6). The section 13 switches from the main lighting to the alarm display. The alarm display continues until door B is next opened.

  In the above description of the operation, the operation of one toilet booth A has been described for convenience, but the same applies to the other toilet booths A. In addition, when the master unit 2, the central display 3 and the external device 4 are connected via a network, the usage status and the room status on the terminal 1 side can be confirmed by these devices.
