When the user does not leave the toilet booth for more than a first time since the entry, a warning is issued, and when the user does not leave the toilet booth for more than a second time which is shorter than the first time since the entry, a preliminary warning is issued for giving a preliminary notice to the user.

Description

  The present invention relates to a toilet system provided in a private room of a toilet.

  Conventionally, there has been known a system that issues an alarm when a user stays in a toilet for a long time, for example, 30 minutes or longer, because there is a risk of poor physical condition or an illegal intruder.

JP 2007-58406 A JP 2007-241446 A Japanese Patent No. 4991771

  When an alarm is issued in the above system, the manager goes to the toilet and takes care of the user who has become unwell.

  However, in recent years, with the increase in the number of comfortable toilets, the number of cases where users other than their intended purpose, such as taking a nap or charging a mobile phone, stay in the toilet for a long time has increased. The frequency that is emitted is increasing. That is, the rate at which warnings are issued in cases where there is no urgency is increasing rather than cases in which the user's poor physical condition or the presence of a suspicious person should be dealt with urgently.

  Even in such a case, when an alarm is issued, the administrator has to go to the toilet and check whether there is an urgent situation, and there is a problem that the number of dispatches increases unnecessarily.

  Further, when a user other than the original purpose occupies the toilet for a long time, there is a problem that the original user cannot use the toilet.

  Therefore, an object of the present invention is to provide a technique for providing a preliminary warning when a user stays in a private room for a predetermined time or more and prompting the user to leave before issuing an alarm.

In order to solve the above problems, the toilet system according to the present invention is:
A detection unit for detecting the state of the user in the toilet booth;
Based on the detection result of the detection unit, a determination unit that determines the user's entrance and exit for the toilet booth,
An alarm unit that outputs an alarm when a user enters the toilet booth and does not leave for more than a first time;
A pre-warning unit that outputs a pre-warning that warns the user when the user does not leave the room for a second time shorter than the first time after the user enters the room;
Have

The toilet system includes a first condition storage unit that stores a plurality of alarm conditions by associating a user condition detected by the detection unit with the first time as an alarm condition.
The alarm unit may acquire a first time corresponding to the state of the user detected by the detection unit from the first condition storage unit, and output the alarm based on the first time. .

The toilet system includes a second condition storage unit that stores a plurality of warning conditions by associating a user condition detected by the detection unit with the second time as a warning condition,
The preliminary warning unit acquires a second time corresponding to the state of the user detected by the detection unit from the second condition storage unit, and outputs the preliminary warning based on the second time. Also good.

  The toilet system detects a state in which the position of the user exceeds a predetermined lower limit height when detecting a state where the position of the user who has entered the toilet booth does not exceed a predetermined lower limit height. Compared to the case, at least one of the first time and the second time may be set shorter.

The toilet system includes a usage rate calculation unit that calculates a usage rate as a percentage of the number of the toilet booths that the user enters the room with respect to the total number of the toilet booths existing in the toilet facility,
When the usage rate exceeds a predetermined value, at least one of the first time and the second time may be set short.

The toilet system may omit the preliminary warning and the warning unit may output the warning when a state preset as a highly urgent state is detected.
The toilet system may output an alarm when the user's luggage is left in the toilet booth after the user leaves.

In order to solve the above problems, the toilet management method according to the present invention is:
Detecting the state of the user in the toilet booth;
Based on the detection result, determining the user's entrance and exit for the toilet booth;
Outputting a warning if the user does not leave the toilet booth for more than a first time after entering the toilet booth;
Outputting a preliminary warning for warning when the user does not leave the room for a second time shorter than the first time after the user enters the room;
Is executed by the computer.

  In the toilet management method, the user's state and the first time are associated with each other as an alarm condition, and a first condition storage unit that stores a plurality of alarm conditions is a first corresponding to the user's state. May be obtained and the alarm may be output based on the first time.

  The toilet management method associates the user's state with the second time as a warning condition, and from a second condition storage unit that stores a plurality of warning conditions, a second corresponding to the user's state. The preliminary warning may be output based on the second time.

  When the toilet management method detects a state where the position of the user who has entered the toilet booth does not exceed a predetermined lower limit height, the state of the user exceeds a predetermined lower limit height. Compared to the case of detection, at least one of the first time and the second time may be set shorter.

The toilet management method includes a usage rate calculation unit that calculates a usage rate as a percentage of the number of the toilet booths that the user enters the room with respect to the total number of the toilet booths existing in the toilet facility,
When the usage rate exceeds a predetermined value, at least one of the first time and the second time may be set short.

  The toilet management method may output the warning by omitting the preliminary warning when a state preset as a highly urgent state is detected.

  The present invention may be a toilet management program for causing a computer to execute the toilet management method. Further, the anonymization program may be recorded on a computer-readable storage medium.

  Here, the computer-readable storage medium refers to a storage medium that stores information such as data and programs by electrical, magnetic, optical, mechanical, or chemical action and can be read from the computer. . Examples of such storage media that can be removed from the computer include a flexible disk, a magneto-optical disk, a CD-ROM, a CD-R / W, a DVD, a DAT, an 8 mm tape, and a memory card.

The condition table of FIG. 8 stores the warning conditions and alarm conditions associated with the first time and the second time, with the detection results of the sensors 92, 421, 461, 462, and 463 as user information. That is, the condition table in FIG. 8 functions as a first condition storage unit and a second condition storage unit. The condition table of FIG. 8 shows an example in which the first condition storage unit and the second condition storage unit are stored as one table, but the first condition storage unit and the second condition storage unit may be separate tables. In FIG. 8, when the sensor 92 detects locking, when the sensor 421 detects sitting, when the human sensors 461, 462, and 463 detect the presence of the user, it is ON, and when not, it is OFF. Show. In the example of FIG. 8, whether or not the user is seated is detected based on the detection result of the seating sensor 421 provided on the Western-style toilet seat, but in the case of a Japanese-style toilet seat, the user is bent on the toilet seat. Whether or not it is a posture to add use (hereinafter this state is also referred to as a seated state) is detected by a human sensor, and is turned on when the posture is added (seated state), otherwise it is turned off. .

  Next, a toilet management method in the toilet system of this embodiment will be described. FIG. 9 is an explanatory diagram of a toilet management method executed by the management server 2 according to the toilet management program.

  First, when the user enters the toilet booth 14 and the detection unit 46 detects this entry, the control device 44 transmits the entry time together with the identification information of the toilet booth 14 to the management server 2. Similarly, when the detection unit 46 detects the exit, the control device 44 transmits to the management server 2 information indicating the exit together with the identification information of the toilet booth 14. In this embodiment, when any of the sensors 92, 421, 461, 462, and 463 is turned on, it is detected that the user has entered the toilet booth 14, and used when all the sensors are turned off. It is detected that the person has left the toilet booth 14.

  When receiving the identification information and entry time of the toilet booth 14 from the control device 44, the management server 2 starts the process of FIG. 9, and stores the identification information and entry time of the toilet booth 14 in the main storage device 22 (step). S10).

  Next, the management server 2 requests the control device 44 of the toilet booth 14 specified by the received identification information to transmit the detection result of each sensor as user information, and the control device 44 transmits the user information, that is, the user's information. A state is acquired (step S20).

  The management server 2 refers to the condition table and acquires the second time corresponding to the user state acquired in step S20 (step S30).

  Then, the management server 2 determines whether or not the second time has elapsed from the room entry time recorded in Step S10 (Step S40). Here, if the second time has not elapsed (step S40, No), the management server 2 determines whether or not the user of the toilet booth 14 has exited, that is, whether or not a notice of exit has been received. (Step S50) If it has left (Step S50, Yes), the process of FIG. 9 is terminated, and if it has not left (Step S50, No), it returns to Step S20.

  On the other hand, when it determines with 2nd time having passed in step S40 (step S40, Yes), the preliminary | backup warning is notified to the control apparatus 44 of the said toilet booth 14 (step S60). Upon receiving this preliminary warning notification, the control device 44 outputs a warning sound from the speaker 433 of the controller 43 and, at the same time, “alerts an alarm in another 5 minutes. If no alarm is required, exit within 5 minutes. Like “Please”, a message for warning is displayed on the display unit 432.

  Moreover, the management server 2 requests | requires transmission of the detection result of each sensor as user information to the control apparatus 44 of the said toilet booth 14, and acquires a user's state from the control apparatus 44 (step S70).

  The management server 2 acquires the first time corresponding to the state of the user acquired in step S70 with reference to the condition table (step S80).

  Then, the management server 2 determines whether or not the first time has elapsed from the entry time recorded in step S10 (step S90). Here, if the first time has not elapsed (step S90, No), the management server 2 determines whether or not the user of the toilet booth 14 has exited, that is, whether or not a notice of exit has been received. (Step S100) If it has left (step S100, Yes), the process of FIG. 9 is complete | finished, and if it has not left (step S100, No), it will return to step S70.

  On the other hand, when it determines with 1st time having passed by step S90 (step S90, Yes), while outputting an alarm and notifying the operator and manager of the management server 2, the control apparatus of the said toilet booth 14 44 is notified (step S110). The alarm is output by displaying an alarm on the display device or the like of the management server 2 to notify the operator of the management server 2 and contacting the administrator by telephone or the like. It is also possible to notify the terminal by e-mail or the like. Moreover, in this embodiment, it can notify not only the user in the said toilet booth 14 but the surrounding person by outputting a warning from the alarm machine 45 of the toilet booth 14. The alarm output may be either the toilet booth 14 or the management server 2, and for example, the alarm output at the toilet booth 14 may be omitted.

  As described above, according to the present embodiment, when a warning is issued according to the usage time from when the user enters the toilet booth until the user exits, the warning is issued by outputting the preliminary warning for warning. Exit can be urged before, and frequent occurrence of alarms can be suppressed.

  Further, if the patient cannot move due to poor physical condition and cannot leave after the preliminary warning, an alarm is output when the usage time reaches the first time. That is, a necessary alarm can be output while suppressing frequent occurrence of the alarm.

  Furthermore, according to the present embodiment, since the timing of the preliminary warning or alarm is changed according to the user's condition, the preliminary warning or alarm can be output at an appropriate timing.

  For example, when the user is normally seated, the seating sensor 421 is turned on, the lower sensor 461 and the middle sensor 463 are turned on, and the condition 1 in FIG. Therefore, when the user is normally seated, a preliminary warning is notified 25 minutes after entering the room, and an alarm is issued 30 minutes.

  On the other hand, if the user's condition is suitable for condition 2, the seating sensor 421 is OFF and the user is in a state of standing (standing position). It is thought that they are used for purposes other than their original purpose, such as changing their clothes while wearing a toilet. For this reason, if the user's condition is in conformity with condition 2, it is assumed that it will take less time than when sitting and using, so it is shorter than condition 1 and spared 15 minutes after entering the room. A warning is notified and an alarm is issued in 20 minutes. Not limited to this, the time from entering the room to the preliminary warning (second time) is 3 to 14 minutes, and the time from entering the room to the alarm (first time) is 5 to 15 minutes. An alarm may be output in a short time. Even when the time until the alarm is set to be short as described above, according to the present embodiment, a preliminary warning is issued before the alarm and the user can be prompted to leave, so that frequent alarms can be prevented.

  In addition, when the user's state meets the conditions 3 and 4, that is, when the lower sensor 461 is ON and the middle sensor 463 is OFF, the user is lying on the floor, peeping, etc. Therefore, a preliminary warning / alarm is given in a shorter time than conditions 1 and 2. For example, a preliminary warning is notified in 5 minutes after entering the room, and an alarm is issued in 10 minutes. As a result, even if the time until the alarm is set long so that the alarm does not occur frequently under normal use conditions, if there is a possibility of annoying behavior such as a user falling down or peeping, a preliminary warning or An alarm can be issued. In order to appropriately detect that the user has fallen, the lower limit height H1 is set to about 10 cm to 50 cm from the seat surface of the Western-style toilet or the installation surface of the Japanese-style toilet. If it exists, that is, if the middle sensor 463 is OFF and the lower sensor 461 is ON, it is determined that the user has fallen. In this case, even if the seating sensor 421 is ON (condition 3) and the seating sensor 421 is OFF (condition 4), the preliminary warning / alarm is performed in a short time similarly.

  Furthermore, when the user's state is in conformity with the conditions 5 and 6, that is, when the upper sensor 462 is ON, the user may be looking through the upper portions of the left and right side walls 14L and 14R. , Preliminary warning / alarm in less than 2 hours. For example, a preliminary warning is notified in 5 minutes after entering the room, and an alarm is issued in 10 minutes. As a result, even if the time until the alarm is set long so that the alarm does not occur frequently in the normal use state, the preliminary warning or the alarm can be issued in a short time if there is a possibility of annoying behavior. In order to appropriately detect the possibility of peeping, the upper limit height H2 is set to about 200 cm to 280 cm from the floor, and when there is a user above this, that is, the upper sensor 462 is ON. It is determined that there is a possibility of peeping. In this case, whether the seating sensor 421 is ON (condition 5) or the seating sensor 421 is OFF (condition 6), the preliminary warning / alarm is performed in a short time similarly.

<Embodiment 2>
The second embodiment is different from the first embodiment in the configuration for changing the timing of the preliminary warning and the warning based on the usage rate of the toilet facility, and the other configurations are the same. For this reason, a different structure from Embodiment 1 is mainly demonstrated, the same code | symbol is attached | subjected to the same element etc., and repeated description is abbreviate | omitted.

  FIG. 10 is a diagram illustrating an example of a condition table according to the second embodiment, and FIG. 11 is an explanatory diagram of a toilet management method according to the second embodiment.

  In the second embodiment, the CPU 21 of the management server 2 also functions as a usage rate calculation unit in addition to the functions described above. The usage rate calculation unit stores in advance the identification information of the toilet booths 14 belonging to each toilet facility, and based on the notification of the entrance / exit of each toilet booth 14, the total number of toilet booths present in each toilet facility, A ratio of the number of the toilet booths in which the user enters the room is obtained as a usage rate.

  In the second embodiment, as shown in FIG. 10, the condition table stores the first time and the second time in association with the usage rate, so that the preliminary warning unit and the warning unit are based on the usage rate. A time 1 and a second time are set, and a preliminary warning and an alarm are issued when this time is reached. Note that it is not necessary to associate the usage rate and the time for all the conditions. In the example of FIG. 10, the usage rate and the first and second times are stored in association with each other for the conditions 1 and 2, and the conditions 3 to 6 Does not correspond to the usage rate.

  When the management server 2 according to the second embodiment receives the identification information and entry time of the toilet booth 14 from the control device 44, the management server 2 starts the processing of FIG. 11 and stores the identification information and entry time of the toilet booth 14 in the main storage device 22. (Step S10), and the usage rate of the toilet booth 14 in the toilet facility to which the toilet booth 14 belongs is obtained (step S15).

  Next, the management server 2 requests the control device 44 of the toilet booth 14 specified by the received identification information to transmit the detection result of each sensor as user information, and the control device 44 transmits the user information, that is, the user's information. A state is acquired (step S20).

  The management server 2 refers to the condition table, and acquires a second time corresponding to the user state and usage rate acquired in step S20 (step S30). For the conditions 3 to 6, the second time corresponding to the state of the user is acquired regardless of the usage rate.

Then, the management server 2 determines whether or not the second time has elapsed from the room entry time recorded in Step S10 (Step S40). Here, if the second time has not elapsed (step S40, No), the management server 2 determines whether or not the user of the toilet booth 14 has left,
That is, it is determined whether or not an exit notification has been received (step S50). If the exit has been exited (step S50, Yes), the processing of FIG. 11 is terminated. If the exit has not been exited (step S50, No), step Return to S15.

  On the other hand, when it determines with 2nd time having passed in step S40 (step S40, Yes), the preliminary | backup warning is notified to the control apparatus 44 of the said toilet booth 14 (step S60). Upon receiving this preliminary warning notification, the control device 44 outputs a warning sound from the speaker 433 of the controller 43 and, at the same time, “alerts an alarm in another 5 minutes. If no alarm is required, exit within 5 minutes. Like “Please”, a message for warning is displayed on the display unit 432.

  Moreover, the management server 2 calculates | requires the usage rate of the toilet booth 14 in the toilet facility to which the said toilet booth 14 belongs (step S65), and transmits the detection result of each sensor as user information to the control apparatus 44 of the said toilet booth 14. The user status is acquired from the control device 44 (step S70).

  The management server 2 refers to the condition table and acquires the first time corresponding to the user state and usage rate acquired in step S70 (step S80). For the conditions 3 to 6, the first time corresponding to the state of the user is acquired regardless of the usage rate.

  Then, the management server 2 determines whether or not the first time has elapsed from the entry time recorded in step S10 (step S90). Here, if the first time has not elapsed (step S90, No), the management server 2 determines whether or not the user of the toilet booth 14 has exited, that is, whether or not a notice of exit has been received. (Step S100) If it has left (step S100, Yes), the process of FIG. 11 is complete | finished, and if it has not left (step S100, No), it will return to step S65.

  On the other hand, when it determines with 1st time having passed by step S90 (step S90, Yes), while outputting an alarm and notifying the operator and manager of the management server 2, the control apparatus of the said toilet booth 14 44 is notified (step S110).

  As described above, according to the second embodiment, in addition to the effects of the first embodiment, the preliminary warning and the alarm can be output at an appropriate timing according to the usage rate.

  For example, when the state of the user is in conformity with the condition 1 and the usage rate is 50% (predetermined value) or more and less than 80%, the control device 44 sets the first time to 30 minutes and the second time. If the usage rate is less than 50%, the first time is set to 45 minutes and the second time is set to 35 minutes. On the contrary, if the usage rate is 80% or more, the control device 44 sets the first time as 20 minutes and the second time as 15 minutes. That is, when the usage rate is low and the toilet booth 14 has a lot of free space, the time until the preliminary warning and warning is set longer. When the usage rate is high and the toilet booth 14 has little free space, the time until the preliminary warning and warning is set. The time is set short so that preliminary warnings and alarms can be output at appropriate timing. In the case of conditions 3 to 6, since it is desirable to output the preliminary warning and alarm in a short time regardless of the number of empty toilet booths, the preliminary warning and alarm are output in a predetermined time regardless of the usage rate.

<Embodiment 3>
The third embodiment is different from the second embodiment in that the preliminary warning is prohibited when the user is in a highly urgent state, and the other configurations are the same. For this reason, a different structure from Embodiment 2 is mainly demonstrated, the same code | symbol is attached | subjected to the same element, and description for the second time is abbreviate | omitted.

  FIG. 12 is a diagram illustrating an example of a condition table according to the third embodiment, and FIG. 13 is an explanatory diagram of a toilet management method according to the third embodiment.

  In a public toilet, the toilet seat device may be removed or devices such as the controller 43 may be disassembled in order to steal the toilet seat device 42 or install a voyeur camera. Therefore, when an abnormal operation is performed on the toilet equipment such as the toilet seat device 42 and the controller 43, the abnormal operation is notified to the management server 2 as the state of the user.

In addition, abnormal operation detection for each device is, for example, that the voltage value or current value of the power applied to the circuit of each device is periodically detected, and if this power value changes due to disassembly or removal, an abnormality has occurred. judge. In addition, a switch is provided that operates when the casing or the like of each device is opened, and an abnormality is detected when this switch is operated.

  In the example of FIG. 12, the toilet seat device 42 and the controller 43 are indicated as ON when an abnormality occurs, and OFF when not abnormal. As shown in FIG. 12, in the third embodiment, when an abnormal operation is performed, that is, when the toilet seat device 42 or the controller 43 is ON is determined as a highly urgent state, the management server 2 When the conditions 7 and 8 are notified, the preliminary warning is prohibited and a warning is output in a relatively short time. In FIG. 12, when the abnormality of the toilet seat device 42 is ON (condition 7) or when the abnormality of the controller 43 is ON (condition 7), the conditions 7 and 8 are performed regardless of ON / OFF of other sensors. It was decided to fall under. Further, in the third embodiment, in addition to the case where the abnormal operation is performed, the cases 3 to 6 are determined as a highly urgent state.

  When the management server 2 of the third embodiment receives the identification information and entry time of the toilet booth 14 from the control device 44, the management server 2 starts the process of FIG. 13 and stores the identification information and entry time of the toilet booth 14 in the main storage device 22. (Step S10), and the usage rate of the toilet booth 14 in the toilet facility to which the toilet booth 14 belongs is obtained (step S15).

  Next, the management server 2 requests the control device 44 of the toilet booth 14 specified by the received identification information to transmit the detection result of each sensor as user information, and the control device 44 transmits the user information, that is, the user's information. A state is acquired (step S20).

  The management server 2 refers to the condition table, and acquires a second time corresponding to the user state and usage rate acquired in step S20 (step S30). For conditions 3 to 8, information indicating prohibition of the preliminary warning is acquired instead of the second time.

  Then, the management server 2 determines whether or not the preliminary warning is prohibited (step S35). If the preliminary warning is prohibited (step S35, Yes), the processing of steps S70 to S110 is performed without performing the preliminary warning. Output an alarm.

  On the other hand, if the preliminary warning is not prohibited in step S35 (No in step S35), the management server 2 proceeds to step S40 and outputs a preliminary warning and an alarm as in the second embodiment (step S40). ~ S110).

  As described above, according to the second embodiment, in addition to the effects of the second embodiment described above, when the urgency is high, a preliminary warning is prohibited and a warning can be output promptly.

  The third embodiment is the same as the second embodiment except for the configuration that prohibits the preliminary warning, but may be the same as the first embodiment.

<Embodiment 4>
The fourth embodiment is different from the first embodiment in that the toilet user quickly outputs an alarm when it detects that a toilet user has brought a suspicious object into the toilet booth 14 and left it. The configuration is the same. For this reason, a different structure from Embodiment 1 is mainly demonstrated, the same code | symbol is attached | subjected to the same element, and description for the second time is abbreviate | omitted.

  FIG. 14 is an explanatory diagram of a sensor for detecting a suspicious object, and FIG. 15 is a diagram illustrating an example of a condition table in the fourth embodiment.

  In FIG. 14, sensors 464 and 465 are sensors that detect the position of an object in the toilet booth 14, and are, for example, laser scanners. The laser scanner as the sensors 464 and 465 scans the toilet booth 14 by irradiating laser light, and measures the reflection position of the laser light. That is, it can be detected that an object is present at a position where the laser beam is reflected. In FIG. 14, a region 460 between the sensors 464 and 465 and indicated by a two-dot chain line is optically scanned with a laser beam. In this way, the blind spot is eliminated by optical scanning from the left and right, but a sensor (laser scanner) that performs optical scanning from another angle may be provided, or light from one sensor from above or from the front. You may make it scan. Further, the sensors 464 and 465 are not limited to laser light, and may be one that measures the reflection position by irradiating microwaves.

  The CPU 441 of the control device 44 periodically acquires the detection results of the sensors 464 and 465 as a user information acquisition unit, and for example, the user brings it into the toilet booth 14 by comparing with the detection results before the user enters the room. The presence / absence of the baggage is detected as user information and transmitted to the management server 2. In FIG. 15, the state where the sensors 464 and 465 are ON indicates that at least one of the sensors 464 and 465 has detected that there is a load.

  When the user has entered the toilet booth 14 and the second time has elapsed since the CPU 21 of the management server 2 as a preliminary warning unit, and the door 9 is unlocked with luggage in the toilet booth 14, That is, a preliminary warning is output when the sensor 92 is turned off. The preliminary warning unit notifies the preliminary warning to the control device 44 of the toilet facility 1 and causes the controller 43 to output it to the user.

  In addition, the CPU 21 of the management server 2 serves as an alarm unit when the user leaves the toilet booth 14 for a first time or more, and the user exits with luggage in the toilet booth 14, that is, An alarm is output when the sensors 92, 421, 461 to 463 are turned off. Here, the alarm output includes display output, sound output, transmission to other devices, and the like. For example, when a user leaves a baggage in the toilet booth 14 and leaves the room, first, a warning is displayed on the display device to notify the operator of the management server 2, and the operator notifies the administrator of the toilet by telephone. contact. The alarm unit may transmit the alarm directly to the administrator's terminal. The alarm unit notifies the controller 44 of the toilet facility 1 of the alarm and operates the alarm device 45.

  When the management server 2 according to the fourth embodiment executes the toilet management method as shown in FIG. 9 described above, the user information acquired in step S20 indicates that the baggage is present in the toilet booth 14 and the door 9 Is information indicating that the sensor is unlocked, that is, when the sensors 464 and 465 are ON, the sensors 461 and 463 are ON, and the sensor 92 is OFF and the condition 9 is met, refer to the condition table. One minute is acquired as the corresponding second time (step S30).

If the management server 2 determines that the second time has elapsed (step S40, Yes), the management server 2 notifies the controller 44 of the toilet booth 14 of a preliminary warning (step S60).
. Upon receiving this preliminary warning notification, the control device 44 outputs a warning sound from the speaker 433 of the controller 43 and displays a message on the display unit 432 such as “Please be careful not to forget your luggage”. And caution about the luggage. In addition, since it is less necessary to perform a preliminary warning when entering the toilet booth 14 but leaving immediately, in this embodiment, the preliminary warning is performed after at least one minute has passed. If the second time is set to zero and the condition 9 is satisfied, the preliminary warning may be output immediately as step S40 always becomes Yes.

  When the user completely leaves, the door 9 is unlocked in the state where the luggage is present in the toilet booth 14, that is, the sensors 464, 465 are ON, and the sensors 461, 463, 92 are OFF. When user information indicating that the condition 10 is met is acquired (step S70), 5 minutes is acquired as the corresponding first time (step S80).

If the management server 2 determines that the first time has elapsed (step S90, Yes), the management server 2 outputs an alarm to notify the operator or administrator of the management server 2 and controls the toilet booth 14. The device 44 is notified (step S110). Note that even if you leave the toilet booth 14 with forgotten baggage, you may return immediately, so in this embodiment it is output after at least 5 minutes, but the first time corresponding to the condition 10 May be set to zero, and if the condition 10 is satisfied, step S90 may always be Yes and an alarm may be output immediately.
As described above, according to the fourth embodiment, when a toilet user forgets a baggage in the toilet booth 14 or leaves a suspicious object, a warning can be promptly issued. Even in this case, a preliminary warning is given at the time of unlocking and attention to the luggage is urged, so that frequent alarms can be prevented.
