It may be configured to detect whether or not it is present. Further, in combination of these, when the open / close sensor 92 detects the locked state, or when the motion sensor 47 detects that there is a user in the toilet booth, the user has entered the toilet booth. When the open / close sensor 92 detects the unlocked state and the motion sensor detects that there is no user in the toilet booth, it detects that the user has left the toilet booth. It may be configured to be used.

The abnormality determination unit 501 compares the pre-entry image taken by the camera 20 with the camera 20 before the user enters the room with the post-exit image taken by the camera 20 with the camera 20 after the user leaves the room. The occurrence of a forgotten object (abnormality) is determined based on the difference between the image before entering the room and the image after leaving the room. For example, when an object that did not exist in the image before entering the room appears in the image after leaving the room, the object is regarded as a forgotten object, and it is determined that the forgotten object has occurred. In this embodiment, an example of detecting the occurrence of a forgotten item as the occurrence of an abnormality is shown, but the present invention is not limited to this, and the taking-out or destruction of the toilet equipment may be detected as a surrounding. For example, when an object that existed before the user entered the room no longer exists after the user leaves the room, it is determined that the equipment has been taken away. Further, when the object that existed before the user enters the room partially disappears after the user leaves the room or the shape changes, it is determined that the equipment is destroyed. In addition, movable equipment such as a filth container and a spare toilet paper should be registered as a movable object, and the position should not exist after the user leaves the room and before the user enters the room. However, if it exists in a different position, it is determined that the movement is normal, and it is not necessary to determine that the equipment has been taken away. Then, the position of the movable object is updated to the position after the transfer. In addition, equipment that can move within a predetermined range (for example, opening and closing), such as the lid of a toilet bowl or a toilet seat, is an object that can move within a predetermined range, and the movable range is registered in advance after the user leaves. , Regardless of the position before the user enters the room, if it is within the movable range, it is determined that the movement is normal, and it is not necessary to determine that it is abnormal.

When it is determined that an abnormality has occurred, the output control unit 502 displays a notification image notifying the abnormality on a display device such as a forgotten item display board 30 provided outside the toilet booth. Here, the notification image is, for example, an image obtained by extracting the difference between the image before entering the room and the image after leaving the room. Further, when this difference is greater than or equal to a predetermined value (threshold value), it is determined that no forgotten object (abnormality) has occurred as noise, and when the magnitude exceeds the predetermined value, it is determined that a forgotten object (abnormality) has occurred. You may judge. The output control unit 502 is a form of the display control unit. Further, the output control unit 502 may function as a sound control unit that transmits a voice signal to the forgotten item display board 30 and outputs a voice message such as "There is a forgotten item." Further, the output control unit 502 may output a message in characters or images, a user's image, or the like to the display device. Further, the output control unit 502 may transmit these information to another device such as the controller 43, the management server 2, and the administrator terminal 3.

When the communication control unit 503 detects that an abnormality has occurred, the communication control unit 503 transmits the event information (forgotten item occurrence information) for notifying the abnormality to the management server 2 or the administrator terminal 3. Identification information for identifying each toilet facility 10 and each toilet booth is assigned to each toilet facility 10 and each toilet booth 14, and the transmission control unit 412 includes this identification information in the event information and manages the server. It may be transmitted to 2 or the administrator terminal 3.

<Toilet management method>
FIG. 11 is a diagram showing the processing of the toilet management method executed by the control device 50 of each toilet booth 14 according to the toilet management program. The control device 50 acquires the detection result by the object detection unit 40 and the open / close sensor 92 periodically or at a predetermined timing, and starts the process of FIG. 11 when the user's entry into the toilet booth 14 is detected. do.

The control device 50 that has started the process of FIG. 11 determines whether or not the door 9 has been unlocked based on the detection result of the open / close sensor 92 (step S10). Here, if the door 9 is not unlocked (steps S10, No), step S10 is repeated, and if it is determined that the door 9 is unlocked, the process proceeds to step S20. Note that step S10 is a step of detecting whether or not the user is in the state immediately before leaving the room, and is not limited to unlocking the door 9, and the user is not in the seated state and flushes the washing water. If it is detected, it may be determined that it is just before leaving the room.

In step S20, the control device 50 outputs a voice message from the speaker 433 of the controller 43 to the user in the toilet booth 14 not to forget something, such as "Are there any things left behind?" do.

Next, the control device 50 determines whether or not the user has left the room based on the detection result of the object detection unit 40 (step S30). Here, if the object detection unit 40 detects the user, that is, if the user has not left (step S30, No), step S30 is repeated, and if it is determined that the user has left, step S40. Move to. The step S30 is not limited to this, and the user who has left the room after a predetermined time has passed after unlocking, the user has passed through the doorway 4, and the user who has analyzed the captured image taken by the camera 20 is the doorway. It may be determined that the user leaves the room by another method such as moving from 4 to the outside.

In step S40, the control device 50 performs a process of detecting a forgotten object (abnormality). The control device 50 compares the pre-entry image taken by the camera 20 with the camera 20 before the user enters the room with the post-exit image taken by the camera 20 with the camera 20 after the user leaves the room. A forgotten object (abnormality) is detected based on the difference between the previous image and the post-exit image. For example, when an object that did not exist in the image before entering the room appears in the image after leaving the room, the object is detected as a forgotten object. As the image after leaving the room, the image taken by the camera 20 at the time when step S40 is executed (current time) is acquired, and as the image before entering the room, the image is acquired at the time when the previous user leaves the room and executes step S40. The image after leaving the room (that is, the image before the current user enters the room) is stored in the storage device, and this is read out and acquired.

Then, the control device 50 determines whether or not the forgotten item has been detected, that is, whether or not the forgotten item has occurred (step S50). If the determination is negative in step S50, the control device 50 ends the process of FIG. 11, and if the determination is positive in step S50, the control device 50 transmits a forgotten item generation signal indicating that a forgotten item has occurred to the forgotten item display board 30. , The forgotten item display board 30 outputs a notification notifying the user of the occurrence of the forgotten item (abnormality) (step S60). The forgotten item generation signal may include a voice message output from the forgotten item display board 30 and information indicating the position of the toilet booth 14 where the forgotten item has occurred.

Further, the control device 50 extracts a portion (difference image) including a difference between the image before entering the room and the image after leaving the room, converts it into a notification image, and transmits it to the forgotten item display board 30 to display it (step S70). The control device 50 is not limited to using the difference image as the notification image, and may transmit the image after exiting as the notification image to the forgotten item display board 30 without extracting the difference image. Further, the control device 50 may transmit the difference image and the image after leaving to the forgotten item display board 30 as a notification image. Then, the image after leaving the room acquired in step S40 is stored in the storage device as the image before entering the room of the next user (step S80). The image before entering the room is not limited to this, and after the end of FIG. 11, the inside of the toilet booth 14 is periodically photographed by the camera 20 and stored in the storage device, and when the next user enters the room, this image is taken. The image immediately before entering the room may be used as the image before entering the room.

Next, the control device 50 transmits the forgotten object generation signal and the notification image to the management server 2 (step S90). Upon receiving this forgotten item generation signal, the management server 2 notifies the manager terminal 3 corresponding to the toilet facility 10 in which the forgotten item has occurred that the forgotten item has occurred.

FIG. 12 is a diagram showing a process in which the forgotten item display board 30 displays a notification image, and FIG. 13 is a diagram showing a display example of the forgotten item display board 30. The forgotten item display board 30 that has received the forgotten item generation signal from the control device 50 executes the process of FIG. 12.

First, the forgotten item display board 30 turns on the forgotten item indicator lamp 37 (step S110). Here, the forgotten item display board 30 may perform control to make the forgotten item indicator stand out by changing the brightness of the forgotten item indicator lamp such as blinking the forgotten item indicator lamp or changing the color. Further, the forgotten item display board 30 outputs a voice message from the speaker 39 based on the forgotten item generation signal (step S120).

Further, the forgotten item display board 30 displays an image (forgotten item position image) showing the position of the toilet booth 14 where the forgotten item has occurred based on the forgotten item generation signal (step S130). In the example of FIG. 13, the map 301 in the toilet facility 10 is displayed, and among them, the toilet booth 14 in which the forgotten item is left is highlighted (shaded in FIG. 13) such as displaying it in a specific color. At the same time, the position of the toilet booth 14 where the forgotten item has occurred is indicated by displaying the character 302 indicating that the forgotten item has occurred.

Further, the forgotten item display board 30 displays the notification image 303 and displays what kind of forgotten item is (step S140). Here, the forgotten item display board 30 may display the entire image (image after leaving) 304 of the toilet booth 14 to indicate where in the toilet booth 14 the forgotten item is. Then, the forgotten item display board 30 determines whether or not the notification is terminated, for example, whether or not a certain period of time has elapsed since the notification image was displayed (step S150). If the affirmative determination is made in step S150, the forgotten item display board 30 turns off the forgotten item indicator lamp, hides the forgotten item position image and the notification image (step S160), and ends the process of FIG.

As described above, according to the present embodiment, when a forgotten item occurs, the forgotten item position image and the notification image are displayed on the forgotten item display board 30 provided outside the toilet booth 14, so that the user who has forgotten the item can be surely forgotten. It is possible to notify. In particular, by displaying the difference between the image before entering the room and the image after leaving the room as a notification image, it is possible to extract and display the forgotten item, so that the user can easily notice that he / she has forgotten. If there are a plurality of forgotten items display boards 30, the notification timing may be determined for each of the forgotten items display boards 30.

<Modification 1-1>
In the above-described first embodiment, the notification image is displayed when a forgotten item occurs, but in the modified example 1-1, the notification image is displayed when the forgotten item occurs and a predetermined notification timing is reached. Since the other configurations are the same as those in the first embodiment, the same elements are designated by the same reference numerals, and the description thereof will be omitted again.

FIG. 14 is a diagram showing the configuration of the control device 50 according to the modified example 1-1. The control device 50 of this modification includes a notification timing determination unit 504 in addition to the configuration of the first embodiment described above.

The notification timing determination unit 504 determines the notification image when a user who has left the toilet booth where a forgotten item (abnormality) has occurred reaches a predetermined area (hereinafter referred to as a display area) where the display of the forgotten item display board 30 can be seen. It is determined that the notification timing of is reached. In this modification, the notification timing determination unit 504 stores in advance the travel time based on the distance from each toilet booth 14 in the toilet facility 10 to the display area, and the forgotten item occurs from the time when the forgotten item occurs. When the movement time set in the toilet booth has elapsed, it is determined that the notification timing has been reached. That is, a user who uses the toilet booth 14 far from the forgotten item display board 30 takes a long time to pass in front of the forgotten item display board 30 after leaving the toilet booth 14, and the toilet booth 14 near the forgotten item display board 30 is used. The user who used it has a relatively short time from leaving the toilet booth 14 to passing in front of the forgotten item display board 30. Therefore, the time from leaving each toilet booth to passing in front of the forgotten item display board 30 is set in advance, and the notification image is displayed at the timing when this time has elapsed.

FIG. 15 is a diagram showing the processing of the toilet management method according to the modified example 1-1. In FIG. 15, the processing of steps S10 to S50 is the same as in FIG. In the case of an affirmative determination in step S50, the control device 50 has whether or not the travel time set in the toilet booth 14 where the forgotten item has occurred has elapsed from the time when the forgotten item has occurred, that is, whether or not the notification timing has been reached. Is determined (step S55). If the affirmative determination is made in step S55, the control device 50 proceeds to step S60 and transmits the forgotten item generation signal to the forgotten item display board 30. The processing after step S60 is the same as that in FIG.

As described above, according to this modification, when the occurrence of a forgotten item is detected, the user who has left the toilet booth 14 is notified of the forgotten item at the timing of passing in front of the forgotten item display board 30 instead of immediately notifying the occurrence of the forgotten item. .. As a result, it can be shown that the notification is to the user, and the notification of the forgotten item can be more reliably transmitted to the user.

<Modification 1-2>
In the above-mentioned modification 1-1, the notification timing is determined according to the elapsed time, but in the modification 1-2, the movement of the user is tracked and the notification image is displayed at the timing when the user moves to the display area. Let me. Since the other configurations are the same as those of the above-mentioned modification 1-1, the same elements are designated by the same reference numerals and the description thereof will be omitted again.

FIG. 16 is a diagram showing the configuration of the control device 50 according to the modified example 1-2. The control device 50 of this modification includes a notification timing determination unit 504 and a movement detection unit 505 in addition to the configuration of the first embodiment described above.

The movement detection unit 505 detects the movement of the user who has left the toilet booth. Based on the detection result of the movement detection unit 505, the notification timing determination unit 504 notifies when a user who has left the toilet booth where a forgotten item has occurred moves to a display area where the display of the forgotten item display board 30 can be seen. It is determined that the timing has been reached.

FIG. 17 is a diagram showing an example of the toilet facility 10 according to the modified example 1-2. The toilet facility 10 includes a plurality of photoelectric sensors 510. FIG. 18 is an explanatory diagram of the movement detection unit 505. The photoelectric sensor 510 has a light projecting unit 511 that linearly irradiates signal light such as laser light, and a light receiving unit 512 that receives signal light. In this modification, as shown in FIGS. 17 and 18, signal light is horizontally irradiated, and a plurality of photoelectric sensors 510 are arranged at predetermined intervals so that the signal light has a mesh shape. The interval for arranging the photoelectric sensors may be arbitrarily set as long as the movement of the user can be detected, and is, for example, 10 mm to 1000 mm, preferably 20 mm to 500 mm, and more preferably 30 mm to 150 mm or 100 mm to 200 mm. Since FIGS. 17 and 18 are schematically shown, the intervals and positions of the photoelectric sensors 510 are different from the intervals at which they are actually arranged.

In the example of FIG. 18, the photoelectric sensor 510 is arranged so that the signal lights sx0 to sx4 and the signal lights sy0 to sy6 are orthogonal to each other, and the user UE shown by the solid line is the signal light sx1 and sx2. , Sy2 to sy4 are blocked. In this case, it is detected that the user is at the intersection of the signal lights sx1 and sx2 and the signal lights sy2 to sy4. Then, when the user UE moves to the position of the alternate long and short dash line, the signal lights sx2, sx3, sy1 to sy3 are blocked, and the signal lights sx1 and sy4 are not blocked. Therefore, the movement detection unit 505 can detect that the user UE has moved to the intersection of the signal lights sx2, sx3, sy1 to sy3 based on the detection result of the photoelectric sensor 510, and by repeating this, the user is tracked. can. In this way, the movement of the user is detected based on the signal light blocked by the user UE. The sensor that detects the position of the user UE is not limited to the sensor that detects the user UE because the signal light is blocked, but the signal light is reflected by the object and the reflected light is received by the receiving unit and used. Based on the distance when there is no user UE, it may be detected that the user UE is present when the reflection is performed at a distance shorter than the reference distance. Further, the sensor for detecting the user UE arranges the sensors in a matrix on the ceiling of the toilet facility 10, detects whether or not the user UE exists directly under each sensor, and detects the existence of the user. The position of the user UE may be detected according to the position of the sensor. Further, the sensor for detecting the user UE is not limited to the photoelectric sensor 510, but the position of the user is detected by lightly scanning the inside of the toilet facility 10 with a laser beam, and the sensor is used by changing the position of the user for each optical scan. A three-dimensional scanner that detects the movement of a person may be used.

In addition, a camera (shooting unit) is provided in the toilet facility, the route of the user leaving each toilet booth 14 and then moving to the display area is photographed, and the photographed image is analyzed by the movement detection unit 505. , The movement of the user may be detected. In this case, the movement detection unit 505 compares the captured image with the background image captured in the absence of the user, extracts the user's image by taking the difference between them, and repeats this periodically. Track users by continuously recording changes in their position. Further, the movement detection unit 505 stores in advance the position of the entrance / exit 4 of each toilet booth 14 and the position of the display area in the captured image, and the user who appears at the position of the entrance / exit 4 of the toilet booth 14 where the forgotten item has occurred. Is tracked to the display area as a user who has left the toilet booth.

FIG. 19 is a diagram showing the processing of the toilet management method according to the modified example 1-2. In FIG. 19, the processing of steps S10 to S50 is the same as in FIG. In the case of an affirmative determination in step S50, the control device 50 detects the position of the user who has left the toilet booth 14 where the forgotten item has occurred (step S53). Then, the control device 50 determines whether or not the notification timing has been reached depending on whether or not the user has reached the display area (step S57). If the affirmative determination is made in step S57, the control device 50 proceeds to step S60 and transmits the forgotten item generation signal to the forgotten item display board 30. The processing after step S60 is the same as that in FIG.

As described above, according to this modification, when the occurrence of a forgotten item is detected, the user who has left the toilet booth 14 is notified of the forgotten item at the timing of passing in front of the forgotten item display board 30 instead of immediately notifying the occurrence of the forgotten item. .. As a result, instead of notifying all users who pass in front of the forgotten item display board, the user who has forgotten the item is selectively notified, so that the notified user knows that he / she has forgotten the item. It will be easier to notice.

<Modification 1-3>
In the above-mentioned modification 1-1, the notification timing is determined according to the elapsed time, but in the modification 1-2, the movement of the user is tracked and the notification image is displayed at the timing when the user moves to the display area. Let me. Since the other configurations are the same as those of the above-mentioned modification 1-1, the same elements are designated by the same reference numerals and the description thereof will be omitted again.

<Modification 2-1>
In the above-mentioned embodiment 2, the person in charge confirms the user who has returned to pick up the forgotten item, but in the modified example 2-1 the configuration in which the management server 2 confirms the user who has returned to pick up the forgotten item. It is supposed to be. Since the other configurations are the same as those in the second embodiment, the same elements are designated by the same reference numerals, and the description thereof will be omitted again.

FIG. 28 is a diagram showing a configuration of the management server 2 according to the modified example 2-1. In addition to the configuration shown in FIG. 10, the management server 2 of this modification includes a user determination unit 217 and a control signal transmission unit 218.

When the user determination unit 217 receives the confirmation request from the control device 50, the image of the user (first user) acquired in step S25 of FIG. 26 (image of the lost person) and the use returned to the acquisition. By comparing with the image of the person (second user), it is determined whether or not the first user and the second user match, that is, whether or not the user who has returned to pick up the forgotten item is the person himself / herself.

Based on the determination result of the user determination unit 217, the control signal transmission unit 218 transmits a control signal for opening the door 9 to the control device 50 if the user who has returned to pick up the forgotten item is the person himself / herself, and picks up the forgotten item. A control signal indicating that the door 9 cannot be opened unless the returned user is the person himself / herself is transmitted to the control device 50.

The control device 50 transmits a forgotten object generation signal and a lost person image to the management server (FIG. 26), and a confirmation request is transmitted to the management server 2 to receive the control signal and open the door 9. (FIG. 27) and the like are the same as those in the second embodiment.

FIG. 29 is a diagram showing a method in which the management server 2 confirms whether or not the user who has returned to pick up the forgotten item is the person who has forgotten the item. When the management server 2 receives the confirmation request from the control device 50, the management server 2 receives a confirmation request.
The process of FIG. 29 is executed.

First, the management server 2 reads out the image of the first user (image of the lost person) from the storage device 23 (step S310), and compares the image of the lost person with the image of the second user who has returned to pick up the forgotten item. , Whether or not the first user and the second user match, that is, whether or not the user who has returned to pick up the forgotten item is the person himself / herself (step S320).

If the affirmative judgment is made in step S320, the management server 2 transmits a control signal to the control device 50 to open the door 9 of the toilet booth 14 in which the forgotten item has occurred (step S330), and if the negative judgment is made, the door is concerned. A control signal indicating that the door cannot be opened is transmitted to the control device 50 (step S340).

According to this modification, the management server 2 can automatically determine whether or not the user who has returned to pick up the forgotten item is the person himself / herself, and the person in charge does not need to wait for this determination.

In this modification, the management server 2 determines whether or not the user who has returned to pick up the forgotten item is the person himself / herself. It may be determined whether or not the person and the second user match, that is, whether or not the user who has returned to pick up the forgotten item is the person himself / herself. Further, when the configuration of this modification and the configuration of the above-described second embodiment are combined, the user determination unit 217 first determines whether or not the user who has returned to pick up the forgotten item is the person himself / herself, and cannot determine that he / she is the person himself / herself. In addition, the person in charge may be presented with images of the first user and the second user to request confirmation. As a result, if the person can be automatically confirmed, the person in charge does not need to perform the confirmation work, and the load on the person in charge can be reduced.
