Description

[Technical Field]

[0001] The disclosed embodiments relate to a toilet system. [Background technology]

[0002] In recent years, with the emergence of genderless toilets, there has been an increasing need for public toilet spaces that are expected to be used by an unspecified number of people to be able to be used safely and securely by anyone. For example, a security system has been provided that uses radio wave sensors to detect only the abnormal behavior of suspicious individuals in enclosed spaces such as toilet booths where personal privacy is required (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-241446 Summary of the Invention [Problem to be solved by the invention]

[0004] However, there is room for improvement in the above-mentioned conventional technology. In the above-mentioned conventional technology, a radio wave sensor is installed in each of multiple toilet booths, and only the abnormal state of a suspicious person in the toilet booth is detected. However, a toilet space has various areas other than the area where the toilet booths are installed, and it is difficult to properly determine the behavior of a person across such areas. As such, there is room for improvement in the determination in the toilet space using the above-mentioned conventional technology. Therefore, it is desired to properly determine the presence of a person in the toilet space so that areas other than the toilet booths in the toilet space can also be managed.

[0005] In view of the above, the challenge is to appropriately determine whether there are people in the toilet space.

[0006] The disclosed embodiments aim to provide a toilet system that can appropriately make determinations regarding people in a toilet space. [Means for solving the problem]

[0007] A toilet system according to one aspect of the embodiment includes a detection sensor that detects the behavior of a person who is located in a toilet space having multiple toilet facilities, a behavior pattern determination unit that determines the behavior pattern of the person in the toilet space based on the detection results of the detection sensor, and a behavior pattern determination unit that determines whether the behavior pattern of the person satisfies predetermined conditions, wherein the toilet space is divided into multiple management areas, and the behavior pattern determination unit determines the behavior pattern of the person who moves between the multiple management areas.

[0008] According to one aspect of the embodiment, a toilet system uses detection information detected by a detection sensor (hereinafter simply referred to as "sensor") in a toilet space partitioned into multiple management areas (hereinafter simply referred to as "areas" or "zones") to determine the behavioral patterns of occupants moving between the multiple management areas, and determines whether the behavioral patterns of occupants satisfy predetermined conditions, thereby making appropriate judgments based on the movement of people between the multiple management areas. Therefore, the toilet system can appropriately make judgments regarding people in the toilet space. For example, behavioral patterns, such as users' movement between zones within the toilet space, can be classified into certain patterns. Therefore, the toilet system can detect suspicious activity within the toilet space by detecting this movement between zones and determining whether it is normal or abnormal.

[0009] In a toilet system according to one aspect of the embodiment, the toilet space is divided into a toilet booth in which a toilet bowl is installed as a stay area, and a space for accessing the toilet booth as a movement area, and the behavior pattern determination unit determines the type of behavior pattern of the occupant moving between the stay area and the movement area.

[0010] According to one aspect of the embodiment, a toilet system can appropriately determine a person's behavioral pattern by determining the type of behavioral pattern of a person moving between a stay area including a toilet booth and a movement area to access the toilet booth. Therefore, the toilet system can appropriately determine the person's behavioral pattern in the toilet space. For example, the toilet system can appropriately detect suspicious behavior such as excessive entry and exit to a toilet booth (also called a "private toilet").

[0011] In one aspect of the embodiment, the behavior pattern determination unit determines the type of behavior pattern of the entrant moving from an entrance / exit area corresponding to the entrance / exit of the toilet space to the movement area, or the type of behavior pattern of the entrant moving from an outside area provided outside the toilet space to the entrance / exit area.

[0012] According to one aspect of the embodiment, the toilet system can appropriately determine the behavioral pattern of a person by determining the type of behavioral pattern of the person moving from the entrance / exit area to the transfer area or from the area outside the toilet space to the entrance / exit area. Therefore, the toilet system can appropriately determine the person in the toilet space. For example, the toilet system can appropriately detect suspicious behavior regarding entry and exit into the toilet space.

[0013] In a toilet system according to one aspect of the embodiment, the behavior pattern determination unit determines that the behavior of the entrant is abnormal or that the entrant is in an abnormal state if the entrant's behavior pattern does not satisfy the specified condition.

[0014] According to one aspect of the embodiment, a toilet system can appropriately determine whether there is something wrong with a person in the toilet space by determining that the behavior of the person in the toilet space is abnormal or that the person in the toilet space is in an abnormal state when the behavior pattern of the person in the toilet space does not satisfy a predetermined condition. Therefore, the toilet system can appropriately determine whether there is something wrong with a person in the toilet space. For example, the toilet system can appropriately determine whether there is something wrong with a person in the toilet space by determining that there is abnormal behavior or that the user is in an abnormal state when the behavior does not satisfy a predetermined condition (e.g., a normal pattern in a matrix, etc.).

[0015] In one aspect of the embodiment, the behavior pattern determination unit determines the type of behavior pattern of the entrant using the detection time of the entrant in each of the multiple management areas.

[0016] According to one aspect of the embodiment, a toilet system can appropriately determine a person's behavior pattern by determining the type of the person's behavior pattern using the detection time of the person in each of multiple management areas. Therefore, the toilet system can appropriately determine the person's behavior pattern in the toilet space. During normal use, there can be significant differences in the amount of time spent in each area of ​​the toilet space, such as a short stay time in the movement area and a long stay time in the stay area. Therefore, by taking into account the detection time in each area, the toilet system can make more accurate determinations and appropriately detect suspicious behavior, etc.

[0017] In a toilet system according to one aspect of the embodiment, the detection sensor is a sensor included in toilet equipment provided in the toilet space or in washroom equipment provided in the toilet space.

[0018] According to one aspect of the embodiment, a toilet system uses sensors included in various facilities such as toilet equipment and washbasin equipment, i.e., sensors installed in devices within the toilet space, enabling detection without the need for additional sensors. Therefore, the toilet system can appropriately determine whether a person is present in the toilet space. The facilities may be various facilities installed in the toilet space, and the sensors may be various sensors, such as a sensor for private parts washing, a door sensor, a faucet sensor, a sensor installed on a mirror, a sensor installed on a diaper changing sheet, etc.

[0019] In a toilet system according to one aspect of the embodiment, the toilet equipment includes a toilet bowl or a urinal, and the detection sensor is a sensor provided in the toilet bowl or the urinal.

[0020] According to one aspect of the embodiment, the toilet system uses a sensor included in the toilet or urinal, thereby enabling detection without the need for an additional sensor, etc. Therefore, the toilet system can appropriately determine whether a person is present in the toilet space.

[0021] In one aspect of the embodiment, the toilet system includes a first sensor provided in a toilet booth in which a toilet bowl is installed, and the detection range of the first sensor includes the interior space of the toilet booth and a portion of the space for accessing the toilet booth.

[0022] According to one aspect of the embodiment, a sensor installed in a toilet booth where a toilet bowl is installed has a detection range that includes the interior space of the toilet booth and a portion of the space for accessing the toilet booth, thereby enabling appropriate detection of human movement, without the need for additional sensors. Therefore, the toilet system can appropriately determine the presence of a person in the toilet space. For example, the toilet system can easily track a person's behavior (movement) by detecting both the stay area and the movement area using a sensor installed in the toilet bowl. Furthermore, for example, the toilet system can detect a person's behavior (movement) without the need for additional sensors in the movement area.

[0023] In a toilet system according to one aspect of the embodiment, the behavior pattern determination unit determines, based on the behavior pattern of the person entering the toilet space determined by the behavior pattern determination unit, that the behavior pattern is that of a worker performing work related to managing the toilet space in the toilet space.

[0024] According to one aspect of the embodiment, a toilet system can appropriately identify workers in the toilet space by determining, based on the behavioral patterns of people in the toilet space, that the behavioral patterns are those of workers performing work related to the maintenance of the toilet space. Therefore, the toilet system can appropriately determine people in the toilet space. For example, since workers such as cleaning workers (also simply referred to as "cleaners") who clean the toilet space may perform irregular behavior, which may be erroneously determined as abnormal behavior, the toilet system can prevent erroneous determination of the workers as suspicious by separately determining the behavioral patterns of the workers. Note that the workers are not limited to cleaners, and can include various workers who perform work related to the maintenance of the toilet space, such as equipment replenishers who replenish supplies and inspection workers who inspect the toilet space.

[0025] In one aspect of the embodiment, the toilet system has a first mode in which the behavior pattern determination unit determines the behavior pattern of the entrant or the behavior pattern determination unit determines the behavior pattern of the entrant, and a second mode in which a worker performs work related to managing the toilet space in the toilet space, and when the second mode is selected, the first mode is not executed.

[0026] According to one aspect of the embodiment, when the second mode in which a worker works in the toilet space is selected, the first mode is not executed, which performs at least one of determining the behavior pattern of a person entering the toilet space and determining the behavior pattern of a person entering the toilet space. By not executing the first mode, the toilet system can prevent a determination based on the worker's behavior by not performing a determination while the worker is working. Therefore, the toilet system can appropriately determine people in the toilet space. For example, since workers such as cleaning workers (cleaners) who clean the toilet space may behave irregularly, and such behavior may be erroneously determined as abnormal behavior, the toilet system can prevent a worker from being erroneously determined as a suspicious person by not performing a determination while the worker is working. [Effects of the Invention]

[0029] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the toilet system disclosed in the present application will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the following embodiments.

[0030] <1. Embodiment> <1-1. Toilet space example> First, an example of a toilet space will be described using FIG. 1. FIG. 1 is a diagram showing an example of a toilet target according to an embodiment. FIG. 1 conceptually shows the physical arrangement of the toilet target. Note that the toilet space 21 shown in FIG. 1 is merely an example, and the toilet space 2 may be a toilet space with any configuration and any layout, as long as it is a toilet space to which management processing by the toilet system 1 can be applied. For example, the toilet space 2 may be a toilet space that does not include a urinal 20 (e.g., toilet space 22, etc.). Note that when describing toilet spaces such as the toilet space 21 and the toilet space 22 without distinguishing between them, they may be referred to as the "toilet space 2." In FIG. 1, the toilet space 2 is shown as two toilet spaces, 21 and 22, but the toilet target may include three or more toilet spaces 2.

[0031] The toilet space 2 is divided into multiple management areas. The toilet space 21 shown in FIG. 1 is divided into multiple management areas, areas A1-A5 and A7. For example, area A1 is divided as a stay area (also called a "stay zone") including toilet booths TB1-TB4, which are toilet booths that form private spaces. Toilet booth TB1 has an openable / closable door D1, allowing a person to enter toilet booth TB1 from area A4 and exit from toilet booth TB1 to area A4. For example, as shown in FIG. 1, when door D1 is in an open state, a person can enter toilet booth TB1 from area A4 and exit from toilet booth TB1 to area A4. Similarly, toilet booths TB2-TB4 each have openable / closable doors D2-D4, allowing a person to enter each of toilet booths TB2-TB4 from area A4 and exit each of toilet booths TB2-TB4 to area A4.

[0032] When describing toilet booths TB1 to TB4 and other toilet booths provided in toilet space 2 without distinction, they may be referred to as "toilet booth TB," and when describing doors D1 to D4 and other doors without distinction, they may be referred to as "door D." For example, when door D is in the open state, a person can move between the space corresponding to area A4 and the space within toilet booth TB.

[0033] FIG. 1 illustrates an example in which the toilet space 2 has four toilet booths TB, but the toilet space 2 may have three or fewer or five or more toilet booths TB. The toilet booths TB are spaces (private spaces) separated by partitions (room dividers). Each toilet booth TB is equipped with a toilet bowl 10 and functions as a place where people defecate. Each toilet booth TB is also equipped with an openable door (not shown) for entering the toilet booth TB. The doors of each toilet booth TB are similar to those provided in general toilet booths TB, and therefore detailed description thereof will be omitted. The toilet booth TB does not have to be a space that is completely separated by a partition; there may be portions at the top or bottom of the partition that are not separated from adjacent toilet booths TB or other spaces (for example, spaces partitioned into area A4).

[0034] In FIG. 1, a toilet bowl 10 11 is placed in the toilet booth TB1. 12 is placed in the toilet booth TB2. 13 is placed in the toilet booth TB3. 14 The toilet is placed in the toilet booth TB4. 11 ~10 14 When describing toilets without distinguishing between them, they may be referred to as "toilet bowl 10." The toilet space 21 is partitioned into a toilet booth TB in which the toilet bowl 10 is installed as an area A1, which is a staying area.

[0035] FIG. 1 shows an example in which there are four toilet bowls 10, but any number of toilet bowls 10 can be used as long as the desired treatment can be performed, and the number of toilet bowls 10 may be three or less or five or more. Details of the functions of the toilet bowls 10 will be described later. In the following, where necessary, the toilet bowl 10 may be read as the toilet booth TB in which the toilet bowl 10 is placed, and the toilet booth TB may be read as the toilet bowl 10 placed in the toilet booth TB. For example, the toilet bowl 10 11may be read as toilet booth TB1, and toilet booth TB1 is a toilet 10 11 It can also be read as:

[0036] In FIG. 1, the toilet space 21 includes a urinal 20 11 , urinal 20 12 , urinal 20 13 , urinal 20 14 , urinal 20 15 The space in which the urinal 20 is placed is defined as an area A2, which is a stay area. 11 ~20 15 When describing urinals arranged in the toilet space 2 without distinction, they may be referred to as "urinals 20". In Fig. 1, a case where there are five urinals 20 is shown as an example, but any number of urinals 20 can be used as long as the desired processing can be performed, and the number of urinals 20 may be four or less or six or more. Note that the management area of ​​the toilet space 2 does not have to include the space corresponding to area A2.

[0037] In FIG. 1, the toilet space 21 includes a washroom facility 30 11 , Washroom facilities 30 12 , Washroom facilities 30 13 , Washroom facilities 30 14 , Washroom facilities 30 15 The space where the washroom equipment 30 is placed is defined as an area A3, which is a stay area. 11 ~30 15 When describing the washroom facilities arranged in the toilet space 2 without distinguishing between them, they may be referred to as "washroom facilities 30." In FIG. 1, a case where there are five washroom facilities 30 is shown as an example, but any number of washroom facilities 30 may be adopted as long as the desired processing can be performed, and the number of washroom facilities 30 may be four or less or six or more.

[0038] In addition, in FIG. 1, the area A3 includes a hand dryer 40 11 , hand dryer 40 12 , hand dryer 40 13 Hand dryers 40 11 ~40 13When describing hand dryers arranged in toilet space 2 without distinguishing between them, they may be referred to as "hand dryer 40." Although FIG. 1 shows an example in which there are three hand dryers 40, any number of hand dryers 40 may be used as long as the desired processing can be performed, and the number of hand dryers 40 may be two or less or four or more. Furthermore, hand dryers 40 may be arranged in an area separate from washroom equipment 30.

[0039] In FIG. 1, the toilet space 21 is partitioned as area A4, which is a space for accessing the toilet booth TB, and is a movement area (also called a "movement zone"). The term "access" here is a concept that includes the ability of a person to move into that space, and may mean, for example, a person moving between the spaces corresponding to that area. Area A4 is, for example, an area where no equipment is located, and functions as a free zone. Area A4 is adjacent to other areas, such as area A1 including the toilet booth TB, area A2 where the urinal 20 is located, and area A3 where the washroom equipment 30 is located, and is an area where each area is accessible.

[0040] In Fig. 1, the toilet space 21 is partitioned as an area A5, which is an entrance area, in the space corresponding to the entrance ET1 of the toilet space 21. Area A5 is an area adjacent to area A6, which is an outside area corresponding to the passage outside the toilet space 21, and a person enters the toilet space 21 by passing through the entrance ET1 from the space (passage) corresponding to area A6 into the space (entrance space) corresponding to area A5.

[0041] In this way, area A6, which is an outer area, is provided outside the toilet space 21. For example, the space including the toilet space 21 and its surrounding space (for example, the space for accessing the toilet space 21) is divided into areas A1 to A7, including area A6, which is an outer area for accessing area A5, which is the entrance / exit area of ​​the toilet space 21. Furthermore, area A5 is an area adjacent to area A4, and people move from the space corresponding to area A5 (entrance / exit space) to the space corresponding to area A4 (free zone), and then move to the area where each facility is provided (areas A1 to A3, etc.).

[0042] In FIG. 1, the toilet space 21 is partitioned as an area A7, which is a space where cleaning tools and the like are stored and is a stay area. Also in FIG. 1, cleaning equipment 45, such as a cleaning faucet, is provided in the area A7. The structure (wall, etc.) that forms the area A7 has an openable door D11, allowing a person to enter the area A7 from the area A4 and exit from the area A7 to the area A4. For example, when the door D11 is in the open state as shown in FIG. 1, a person can enter the area A7 from the area A4 and exit from the area A7 to the area A4. Note that the management area of ​​the toilet space 2 does not necessarily include a space corresponding to the area A7.

[0043] <1-2. Overview of Toilet Management> Next, an overview of toilet management performed by the toilet system 1 (see FIG. 3) for the above-described toilet space 2 will be described with reference to FIG. 2. FIG. 2 is a diagram showing an example of toilet management processing according to an embodiment. Below, an example will be described in which it is determined whether a person's behavior in the toilet space 21 is a normal behavior pattern or an abnormal behavior pattern based on the above-described areas A1 to A7.

[0044] The toilet system 1 determines the behavior pattern of a person entering the toilet space 21 (hereinafter referred to as "subject X") based on the detection results of the detection sensor. Details of the detection sensor will be described later. For example, the toilet system 1 determines the movement route of the subject X through each zone of areas A1 to A7 as the behavior pattern based on the detection results of the detection sensor. For example, the toilet system 1 determines the movement route of the subject X from entering the toilet space 21 to leaving the toilet space 21, such as area A6, area A5, area A4, etc., as the behavior pattern.

[0045] Then, the toilet system 1 determines whether the determined behavior pattern of the subject X satisfies a predetermined condition. For example, the toilet system 1 determines whether the determined behavior pattern of the subject X satisfies a condition indicating an abnormal behavior pattern (also referred to as a "condition requiring caution"). For example, if the determined behavior pattern of the subject X satisfies the condition requiring caution, the toilet system 1 determines that the behavior pattern of the subject X is an abnormal behavior pattern (also referred to as a "behavior pattern requiring caution"). Furthermore, if the determined behavior pattern of the subject X does not satisfy the condition requiring caution, the toilet system 1 determines that the behavior pattern of the subject X is a normal behavior pattern. For example, if the behavior pattern of the subject X does not satisfy the condition requiring caution, the toilet system 1 determines that the subject X is a normal toilet user.

[0046] In Figure 2, the toilet system 1 determines that a behavior pattern such as that shown in the normal behavior pattern list PT1 is a normal behavior pattern. For example, the toilet system 1 determines that the behavior pattern of subject X is a normal behavior pattern when it is area A6, area A5, area A4, area A1, area A4, area A3, area A5, and area A6. In other words, the toilet system 1 determines that a behavior pattern in which subject X uses the toilet bowl 10 and washes his or her hands in the washbasin fixture 30 (normal behavior pattern #1 in Figure 2) is a normal behavior pattern.

[0047] For example, the toilet system 1 determines that the behavior pattern of the subject X is a normal behavior pattern when the behavior pattern is in areas A6, A5, A4, A2, A4, A3, A5, and A6. That is, the toilet system 1 determines that a behavior pattern in which the subject X uses the urinal 20 and washes his / her hands in the washroom facility 30 (normal behavior pattern #2 in FIG. 2) is a normal behavior pattern.

[0048] For example, the toilet system 1 determines that the behavior pattern of the subject X is a normal behavior pattern when the behavior pattern is area A6, area A5, (area A4), area A3, (area A4), area A5, and area A6. That is, the toilet system 1 determines that a behavior pattern of only washing hands in the washroom facility 30 (normal behavior pattern #3 in FIG. 2) is a normal behavior pattern, regardless of whether the subject X passes through area A4, which is a free zone.

[0049] On the other hand, in FIG. 2, the toilet system 1 determines that a behavior pattern such as that shown in the list of abnormal behavior patterns PT2 is an abnormal behavior pattern (a behavior pattern requiring caution). For example, if the behavior pattern of the subject X includes a behavior of going back and forth between area A4 and area A5, the toilet system 1 determines that the behavior pattern is a behavior pattern requiring caution. That is, the toilet system 1 determines that a behavior pattern such as loitering in a zone without any equipment (hereinafter also referred to as "equipment") (abnormal behavior pattern #1 in FIG. 2) is a behavior pattern requiring caution. For example, if the behavior pattern of the subject X satisfies the condition requiring caution, the toilet system 1 determines that the subject X is not a normal toilet user, that is, a person other than a normal toilet user such as a suspicious person, or that even if the subject X is a normal toilet user, the subject X is not in a normal state (an abnormal state).

[0050] For example, the toilet system 1 determines that the behavior pattern of the subject X is a behavior pattern requiring caution when the behavior pattern includes going back and forth between area A1 and area A2. In other words, the toilet system 1 determines that a behavior pattern in which the subject X uses the toilet bowl 10 and the urinal 20 simultaneously (during one use of the toilet space 2) (abnormal behavior pattern #2 in FIG. 2) is a behavior pattern requiring caution.

[0051] For example, if the behavior pattern of subject X includes a behavior of entering and leaving only area A1, the toilet system 1 determines that the behavior pattern is a behavior pattern requiring caution. That is, the toilet system 1 determines that a behavior pattern of entering and leaving only one stay area (abnormal behavior pattern #3 in FIG. 2) is a behavior pattern requiring caution. Note that the toilet system 1 may also determine that a behavior pattern of entering and leaving only area A2 or area A3 is a behavior pattern requiring caution.

[0052] For example, if the behavior pattern of subject X includes entering and exiting another stall (toilet booth TB) in area A1, the toilet system 1 determines that the behavior pattern is a behavior pattern requiring caution. That is, the toilet system 1 determines that a behavior pattern of entering and exiting multiple toilet booths TB (abnormal behavior pattern #4 in FIG. 2) is a behavior pattern requiring caution. Note that if area A2 or area A3 is divided into stalls, the toilet system 1 may also determine that a behavior pattern of entering and exiting another stall in area A2 or area A3 is a behavior pattern requiring caution.

[0053] In addition, the toilet system 1 may determine (judge) whether an abnormal behavior pattern is a warning or an abnormality depending on the degree of the abnormal behavior pattern and the importance (weight) of the equipment (also called "fixtures"), but this point will be discussed later.

[0054] <1-3. Toilet space layout> The arrangement of the toilet space 2 will be briefly described. The toilet space 2 may be provided in any location as long as it is a space where the toilet space 2 can be physically arranged. In other words, the location where the toilet space 2 is provided can be any location. For example, the toilet space 2 may be provided in a commercial facility such as a department store. Furthermore, the location where the toilet space 2 is provided is not limited to a commercial facility such as a store, but may be various other facilities. For example, the location where the toilet space 2 is provided may be an amusement park, a stadium, an office building, etc. For example, the location where the toilet space 2 is provided may be a toilet provided in an area such as a tourist destination. For example, the location where the toilet space 2 is provided may be a park, a parking lot, etc. In other words, the toilet may be provided outdoors, such as in a park or a parking lot. In this way, the location where the toilet space 2 is provided may be any location as long as there is space where the toilet space 2 can be arranged.

[0055] <1-4. Toilet system configuration> Next, the configuration of the toilet system 1 will be described with reference to Fig. 3. Fig. 3 is a diagram showing an example of the configuration of a toilet system according to an embodiment. Specifically, Fig. 3 shows the configuration of the toilet system 1.

[0056] The toilet system 1 has an information processing device (toilet management device 100 in FIG. 3) that executes toilet management processing. The toilet system 1 also has an information processing device (collection device 50 in FIG. 3) that collects information used in the toilet management processing. The toilet system 1 shown in FIG. 3 has the toilet management device 100, a collection device 50, a detection sensor 21, a detection sensor 101, a detection sensor 201, a detection sensor 301, and a detection sensor 401. Note that the toilet system 1 may include a plurality of toilet management devices 100, a plurality of collection devices 50, a plurality of detection sensors 21, a plurality of detection sensors 101, a plurality of detection sensors 201, a plurality of detection sensors 301, etc.

[0057] The detection sensor 21 performs detection related to the toilet space 2. The detection sensor 21 detects the behavior of an entrant, i.e., a person located in the toilet space 2. The detection sensor 21 may be a sensor whose detection range is area A4 or area A5, etc. The detection sensor 21 may be realized by various sensors. For example, the detection sensor 21 may be various sensors such as a human body detection sensor, a behavior detection sensor, a presence detection sensor, etc.

[0058] When the detection sensor 21 has the area A5 as its detection range, it may function as a detection sensor that detects people entering and exiting the toilet space 2. In this case, the detection sensor 21 may be an image sensor (behavior detection sensor) that captures an image of the entrance and exit of the toilet space 2. Note that the above is merely an example, and the detection sensor 21 may have the area A1 as its detection range and detect people located in the area A1.

[0059] The detection sensor 21 includes, for example, a communication unit (e.g., a communication circuit, etc.) with a wireless communication function, and is connected to the collection device 50 so as to be able to communicate wirelessly. For example, when the detection sensor 21 detects a person entering or leaving the toilet space 2, it transmits detection information indicating the detection and the date and time of the detection to the collection device 50 together with identification information (e.g., ID) that identifies the toilet space 2. For example, the detection sensor 21 transmits detection information indicating the time (usage time) from when the person entered the toilet space 2 until when they left to the collection device 50 together with identification information (e.g., ID) that identifies the toilet space 2. Note that if the toilet system 1 can perform the desired process without using the detection sensor 21, the toilet system 1 does not need to include the detection sensor 21.

[0060] The toilet 10 is a toilet fixture used by people using the toilet when they excrete feces, urinate, etc. The toilet 10 is placed in a toilet booth TB provided within the toilet space 2. For example, the toilet 10 has a toilet seat device including a toilet seat on which a person sits and an operating unit for operating a nozzle for discharging water for flushing. In addition to the toilet seat device, the toilet 10 also has various components for realizing the function of a toilet, such as a toilet lid and toilet bowl, but detailed explanations will be omitted. Note that the toilet 10 does not have to be included in the toilet system 1.

[0061] The detection sensor 101 detects the toilet bowl 10. The detection sensor 101 detects the behavior of an entrant, that is, a person located in the toilet space 2. For example, the detection sensor 101 may be a sensor included in the toilet bowl 10, which is toilet equipment provided in the toilet space 2. For example, the detection sensor 101 may be a first sensor provided in the toilet booth TB in which the toilet bowl 10 is installed. In this case, the detection range of the first sensor (range DR11 in FIG. 7) may include the interior space of the toilet booth TB and part of the space for accessing the toilet booth TB, but this point will be described later.

The detection sensor 101 may function as a detection sensor that detects a person entering or exiting the toilet booth TB in which the toilet bowl 10 is arranged. The detection sensor 101 may be realized by various sensors, for example, the detection sensor 101 may be various sensors such as a human body detection sensor, a behavior detection sensor, a seat detection sensor, etc. The detection sensor 101 may be a door sensor provided on the door of the toilet booth TB, etc., that detects the opening and closing of the door of the toilet booth TB. The detection sensor 101 may be an image sensor that captures an image near the door of the toilet booth TB. The detection sensor 101 may be a seat sensor that detects a person sitting on the toilet bowl 10.

[0063] While the above is an example in which the detection sensor 101 is capable of detecting people entering and exiting the toilet booth TB, the detection sensor 101 is not limited to this, and may also be a means for detecting toilet use, such as use of the toilet bowl 10, use of the toilet seat, and operation of the toilet lid. The toilet bowl 10 and the detection sensor 101 may be integrated. In this case, the toilet bowl 10 having the detection sensor 101 may be included in the toilet system 1. The location of the detection sensor 101 is not particularly limited, and it may be installed on the ceiling, wall, floor, etc. of the toilet booth TB, or it may be mounted on the toilet seat of the toilet bowl 10.

[0064] The detection sensor 101 includes, for example, a communication unit (e.g., a communication circuit, etc.) with wireless communication capabilities, and is connected to the collection device 50 so as to be able to communicate wirelessly. For example, when the detection sensor 101 detects a person entering or exiting a toilet booth TB in which a toilet 10 is placed, it transmits detection information indicating the detection and the date and time of the detection, together with identification information (e.g., ID) that identifies the toilet 10 or the toilet booth TB in which the toilet 10 is placed, to the collection device 50. For example, the detection sensor 21 transmits detection information that indicates the time (usage time) from when a person entered the toilet booth TB in which the toilet 10 is placed until when they left the booth, together with identification information (e.g., ID) that identifies the toilet 10 or the toilet booth TB in which the toilet 10 is placed, to the collection device 50. Note that if the toilet 10 is not included in the toilet management targets of the toilet system 1, the toilet system 1 does not need to include the detection sensor 101.

For example, the detection sensor 21 transmits detection information indicating the time (usage time) during which the person is using the urinal 20 (e.g., from the time the person approaches the urinal 20 until the time the person leaves the urinal 20) to the collection device 50 together with identification information (e.g., ID) that identifies the urinal 20. Note that if the urinal 20 is not included in the toilet management targets of the toilet system 1, the toilet system 1 does not need to include the detection sensor 201.

[0069] The washbasin fixture 30 is a facility used by people using the toilet to wash their hands, wash their face, and look in the mirror. For example, the washbasin fixture 30 functions as an automatic faucet. For example, the washbasin fixture 30 has a faucet with the function of an automatic faucet and a bowl portion that receives water from the faucet. Note that the washbasin fixture 30 does not necessarily have to be included in the toilet system 1.

[0070] The detection sensor 301 detects the washroom fixture 30. The detection sensor 301 detects the behavior of an entrant, i.e., a person located in the toilet space 2. For example, the detection sensor 301 may be a sensor included in the washroom fixture 30 provided in the toilet space 2.

Note that the washroom fixture 30 and the detection sensor 301 may be integrated. In this case, the washroom fixture 30 having the detection sensor 301 may be included in the toilet system 1. For example, the detection sensor 301 is provided near the faucet of the washroom fixture 30 and detects the approach of a person's hand to the faucet of the washroom fixture 30. The location of the detection sensor 301 is not particularly limited, and it may be installed on the ceiling, wall, floor, etc. of the toilet space 2.

[0072] The detection sensor 301 includes, for example, a communication unit (e.g., a communication circuit, etc.) with a wireless communication function, and is connected to the collection device 50 so as to be able to communicate wirelessly.

Note that the above is just one example, and detection sensor 401 may be realized by any means that can detect a person's use of hand dryer 40. Note that hand dryer 40 and detection sensor 401 may be integrated. In this case, hand dryer 40 having detection sensor 401 may be included in toilet system 1. For example, detection sensor 401 is provided near the hand insertion opening of hand dryer 40 and detects the approach of a person's hand to hand dryer 40. The location of the detection sensor 401 is not particularly limited, and it may be installed on the ceiling, wall, floor, etc. of the toilet space 2.

[0075] The detection sensor 401 includes, for example, a communication unit (e.g., a communication circuit) with a wireless communication function, and is connected to the collection device 50 so as to be able to communicate wirelessly.

The collecting device 50 receives the detection information of the detection sensor 101 from the detection sensor 101. The collecting device 50 receives the detection information of the detection sensor 201 from the detection sensor 201. The collecting device 50 receives the detection information of the detection sensor 301 from the detection sensor 301.

[0079] The collection device 50 may be located outside the toilet space 2, or may be located inside the toilet space 2. For example, the collection device 50 may be a server device located in a facility where the toilet space 2 is provided. Note that the above is merely an example, and the collection device 50 may have any configuration and arrangement as long as it is able to communicate with each detection sensor, collect information, and transmit the collected information to the toilet management device 100. The collection device 50 may also be integrated with the toilet management device 100. In this case, the toilet management device 100 has the functions of the collection device 50, and collects detection information from each detection sensor.

[0080] The restroom management device 100 is an information processing device (computer) that executes a determination process to determine whether a person is located in the restroom space. For example, the restroom management device 100 may be a cloud server or the like. The restroom management device 100 is communicably connected to the collection device 50 via a predetermined network N such as the Internet, either wirelessly or via a wired connection. Note that the restroom management device 100 may be connected to the collection device 50 in any manner as long as it is possible to send and receive information, and may be communicatively connected wirelessly or via a wired connection.

[0081] The toilet management device 100 uses the information collected by the collection device 50 to execute a determination process to determine whether or not the behavior pattern of the occupant in the toilet space 2 satisfies a predetermined condition. The toilet management device 100 also executes a determination process to determine the behavior pattern of the occupant in the toilet space 2. For example, the toilet management device 100 determines the behavior pattern of the occupant moving between a plurality of management areas.

[0082] The toilet system 1 may include various other components in addition to those described above. For example, the toilet system 1 may include an administrator device (e.g., a computer such as a mobile terminal) used by an administrator who manages the toilet system 1. The toilet system 1 may also include a facility administrator device (e.g., a computer such as a mobile terminal) used by a facility administrator of a facility in which the toilet space 2 is provided. For example, the facility administrator device notifies the facility administrator of information such as the determination result received from the toilet management device 100 by displaying the information on a screen or outputting it as audio. The toilet system 1 may also include an external security company device (e.g., a computer such as a mobile terminal) used by an external security company. For example, the external security company device notifies the person in charge of the external security company of the information by displaying the information such as the determination result received from the toilet management device 100 on a screen or outputting it as audio.

[0083] The toilet system 1 may also include an operator device (for example, a computer such as a mobile terminal) used by an operator, such as a cleaning worker, who performs work related to managing the toilet space 2. For example, the operator device transmits, to the toilet management device 100, information specifying the date and time when work will be performed in the toilet space 2 (also referred to as "work date and time information") in response to an operation by the operator.

[0084] <1-5. Functional configuration of the toilet management device> The functional configuration of the toilet management device will be described below with reference to Fig. 4. Fig. 4 is a block diagram showing an example of the configuration of the toilet management device according to the embodiment.

[0085] 4, the restroom management device 100 has a communication unit 110, a storage unit 120, and a control unit 130. The restroom management device 100 may also have an input unit (e.g., a keyboard or mouse) that accepts various operations from an administrator of the restroom management device 100, and a display unit (e.g., a liquid crystal display) that displays various information.

[0086] The communication unit 110 is realized by, for example, a communication circuit or the like. The communication unit 110 is connected to a predetermined network N (see FIG. 3) by wire or wirelessly, and transmits and receives information to and from an external information processing device. For example, the communication unit 110 is connected to the predetermined network N (see FIG. 3) by wire or wirelessly, and transmits and receives information to and from other devices such as the collection device 50, an administrator device, a facility administrator device, an external security company device, and a worker device.

[0087] The storage unit 120 is realized by, for example, a semiconductor memory element such as a random access memory (RAM) or a flash memory, or a storage device such as a hard disk or an optical disk. For example, the storage unit 120 is a computer-readable recording medium that non-temporarily records data used by a toilet management program such as a determination process.

[0088] 4, the storage unit 120 according to the embodiment includes a placement information storage unit 121, a collected information storage unit 122, a setting information storage unit 123, and a determination information storage unit 124. The storage unit 120 stores various information necessary for processing, including but not limited to the placement information storage unit 121, the collected information storage unit 122, the setting information storage unit 123, and the determination information storage unit 124. For example, the storage unit 120 stores various information (e.g., information related to thresholds) used in the determination processing. For example, the storage unit 120 stores a function for calculating a threshold used in the determination processing and information about the calculated function.

[0089] The placement information storage unit 121 according to the embodiment stores various information relating to the placement of various pieces of equipment that are the detection targets of the toilet system 1. For example, the placement information storage unit 121 stores information relating to the placement of the toilet space 2, toilet bowls 10, urinals 20, and washroom equipment 30. Fig. 5 is a diagram showing an example of the placement information storage unit 121 according to the embodiment. The placement information storage unit 121 shown in Fig. 5 includes items such as "facility," "toilet space," "management area (zone)," "type," and "placement element."

[0090] "Facility" indicates the location where the toilet space is located. Note that "facility" is not limited to structures, and various locations where toilet spaces are located can be registered. "Toilet space" indicates identification information for identifying each toilet space. In Figure 5, for the sake of explanation, the "toilet space" is illustrated with reference numerals such as "21" and "22" assigned to each toilet space, but "toilet space" stores information that can identify the toilet space (for example, a toilet space ID, etc.).

[0091] "Management area (zone)" indicates identification information for identifying each management area (zone). In FIG. 5, for the sake of explanation, the "management area (zone)" is illustrated with symbols such as "A1", "A2", etc., which are assigned to each area of ​​the toilet space 2, but the "management area (zone)" stores information that can identify the management area (zone) (for example, a zone ID, etc.). "Type" indicates information on the type of each area. For example, "type" stores information that indicates the type of the area, such as "stay" or "move".

[0092] The "location element" indicates identification information for identifying the equipment located in the corresponding management area (zone). For example, the "location element" indicates identification information for identifying the equipment, such as the toilet 10, the urinal 20, the washroom equipment 30, the hand dryer 40, and the cleaning equipment 45, located in the corresponding management area (zone). In FIG. 5, for the sake of explanation, the "location element" is labeled "10" 11 " ~ "10 14 "," 20 11 " ~ "20 15 "," 30 11 " ~ "30 15 "," 4011 " ~ "40 13 Although the symbols attached to each component, such as "45" and "46", can be registered in the "location element" as long as it can identify each piece of equipment.

[0093] For example, the "location element" stores information (e.g., a toilet ID) that can identify a toilet located in the corresponding management area (zone). In FIG. 5, the "location element" stores information (e.g., a toilet ID) that can identify a toilet, in association with information (e.g., a toilet booth ID) that can identify the toilet booth TB in which the toilet is located. The "location element" also stores identification information (e.g., a urinal ID) that identifies a urinal located in the corresponding management area (zone), or identification information that identifies a washroom equipment (e.g., a washroom equipment ID). The "location element" also stores identification information (e.g., a hand dryer ID) that identifies a hand dryer located in the corresponding management area (zone), or identification information that identifies a cleaning equipment (e.g., a cleaning equipment ID).

[0094] 5 shows that the toilet space 21 identified by "21" includes, as management areas (zones), an area A1 identified by "A1", an area A2 identified by "A2", an area A3 identified by "A3", an area A4 identified by "A4", an area A5 identified by "A5", and an area A7 identified by "A7". Note that an area A6, which is an external area of ​​the toilet space 21, may also be managed in association with the toilet space 21. In this case, information identifying area A6 (such as a zone ID) may be stored in association with the toilet space 21.

[0095] The area A1, which is the area to stay identified by "A1", is equipped with a toilet 10 installed in a toilet booth TB1. 11 , toilet 10 installed in toilet booth TB2 12 , toilet 10 installed in toilet booth TB3 13 , toilet 10 installed in toilet booth TB4 14The area A1 is an area including toilet booths TB1 to TB4, and the toilet 10 11 ~Toilet bowl 10 14 indicates that the

[0096] In addition, the area A2, which is the stay area identified by "A2", has a urinal 20 11 , urinal 20 12 , urinal 20 13 , urinal 20 14 , urinal 20 15 In addition, the area A2, which is the area to stay identified by "A3", has a washroom facility 30. 11 , Washroom facilities 30 12 , Washroom facilities 30 13 , Washroom facilities 30 143 , Washroom facilities 30 15 , hand dryer 40 11 , hand dryer 40 12 , hand dryer 40 13 indicates that the

[0097] It also indicates that there are no placement elements in area A4, which is a movement area identified by "A4," and area A5, which is a movement area identified by "A5." It also indicates that cleaning equipment 45 is placed in area A7, which is a stay area identified by "A7."

[0098] The arrangement information storage unit 121 may store various types of information according to the purpose, not limited to the above. For example, the arrangement information storage unit 121 may store information (such as a sensor ID) that can identify a sensor (detection sensor) provided corresponding to each facility, in association with the facility.

[0099] Information indicating the specific location of each piece of equipment (e.g., latitude and longitude information, etc.) may be stored in association with each piece of equipment. For example, information indicating the specific location of each toilet space 2 (e.g., latitude and longitude information, etc.) may be stored in association with each toilet space 2. For example, information indicating the specific location of each toilet bowl 10 (e.g., latitude and longitude information, etc.) may be stored in association with each toilet bowl 10. For example, the location information storage unit 121 may store information detected by each urinal 20 or information indicating the specific location of each urinal 20 (e.g., latitude and longitude information, etc.) in association with each urinal 20. For example, the location information storage unit 121 may store information detected by each washbasin fixture 30 or information indicating the specific location of each washbasin fixture 30 (e.g., latitude and longitude information, etc.) in association with each washbasin fixture 30.

[0100] The collected information storage unit 122 stores detection information such as sensor data collected for each toilet space 2. The collected information storage unit 122 stores information received from the collection device 50. The collected information storage unit 122 stores detection information detected by sensors such as the detection sensor 21, the detection sensor 101, the detection sensor 201, the detection sensor 301, and the detection sensor 401. For example, the collected information storage unit 122 stores the location of a person detected by each sensor, the behavioral history of the person, such as the use of equipment, in association with information identifying each sensor.

[0101] For example, the collected information storage unit 122 includes items such as "time," "ID," and "detection information." "Time" indicates the time of detection by the sensor identified by the ID. "ID" indicates the ID (identification information) for identifying the sensor that performed the detection.

[0102] "Detection information" indicates detection information detected by a sensor identified by an ID. For example, the "detection information" stores information indicating the area in which a person detected by a sensor is located. For example, the "detection information" may store information indicating the use of equipment estimated based on a signal detected by a sensor. Note that the above is merely an example, and the "detection information" may store various information detected by a sensor. For example, the "detection information" may store information (e.g., a zone ID) indicating the area in which a person is estimated to be located based on the strength of a signal detected by a sensor.

[0103] In this way, the collected information storage unit 122 stores the date and time when detection was performed by each sensor in association with information identifying each sensor. Note that the above is merely an example, and the collected information storage unit 122 stores various collected information. For example, the collected information storage unit 122 may store information indicating the period during which a person was present in each area, estimated based on detection by a sensor corresponding to each area, in association with information identifying that area. For example, the collected information storage unit 122 may store the start date and time or end date and time of use of each piece of equipment, estimated based on detection by a sensor corresponding to each piece of equipment, in association with information identifying that equipment. In this case, the collected information storage unit 122 may store the date and time when the start or end of use of each toilet 10 was detected in association with information identifying that toilet 10. The collected information storage unit 122 may store the date and time when the start or end of use of each urinal 20 was detected in association with information identifying that urinal 20. The collected information storage unit 122 may store the date and time when the start or end of use of each washroom fixture 30 is detected in association with information that identifies each washroom fixture 30.

[0104] The setting information storage unit 123 stores various setting information related to toilet management. For example, the setting information storage unit 123 stores conditions used in the determination process. For example, the setting information storage unit 123 stores thresholds used in the process. For example, the setting information storage unit 123 stores thresholds used for comparison with the detection time. For example, the setting information storage unit 123 stores information used to calculate various scores (also referred to as "score calculation information").

[0105] The setting information storage unit 123 stores score calculation information including information used to calculate an individual score (also called a "single score") for each behavior included in a behavior pattern. For example, the setting information storage unit 123 stores score calculation information including a list of single score conditions that associate a value used as a single score with a condition when the value is applied as the single score.

[0106] For example, the setting information storage unit 123 stores score calculation information including information used to calculate the score of a behavioral pattern (also referred to as a "total score"). For example, the setting information storage unit 123 stores score calculation information including a function (also referred to as a "total score calculation function") for calculating a total score from the single scores corresponding to each behavior. For example, the setting information storage unit 123 stores score calculation information including a total score calculation function that calculates the sum of the single scores corresponding to each behavior as a total score.

[0107] The setting information storage unit 123 stores information about modes. The setting information storage unit 123 stores information about a plurality of modes including a first mode in which the behavior pattern of a person entering the toilet space 2 is determined by the behavior pattern determination unit 133 or the behavior pattern of a person entering the toilet space 2 is determined by the behavior pattern determination unit 132, and a second mode in which a worker performing work related to managing the toilet space 2 works in the toilet space 2. The setting information storage unit 123 stores information indicating the selected mode.

[0108] The above is merely an example, and the setting information storage unit 123 stores various pieces of set information.

[0109] The determination information storage unit 124 stores various setting information related to determination. For example, the determination information storage unit 124 stores a determination result for each toilet space 2. The determination information storage unit 124 stores the date and time when it was determined that the behavior pattern of the person entering each toilet space 2 satisfies a predetermined condition. For example, the determination information storage unit 124 stores the date and time when it was determined that an abnormality occurred for each toilet space 2. For example, the determination information storage unit 124 stores the date and time when it was determined that an alert was required for each toilet space 2.

[0110] Note that the above is merely an example, and the determination information storage unit 124 stores various information related to the determination. For example, the determination information storage unit 124 may store information such as "undetermined" as the determination result when there is a processing target for which it cannot be determined whether it is abnormal or normal, or for which a determination has not been made.

[0111] Returning to Figure 4, the explanation will continue. The control unit 130 is realized, for example, by a CPU (Central Processing Unit) or GPU (Graphics Processing Unit) executing a program stored inside the toilet management device 100 (for example, a toilet management program such as a determination process according to the present disclosure) using RAM or the like as a work area. The control unit 130 is also realized, for example, by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or FPGA (Field Programmable Gate Array).

[0112] As shown in FIG. 4, the control unit 130 has an acquisition unit 131, a behavior pattern determination unit 132, a behavior pattern judgment unit 133, and a transmission unit 134, and realizes or executes the functions and actions of information processing described below. The internal configuration of the control unit 130 is not limited to the configuration shown in FIG. 4, and may be any other configuration that performs the information processing described below. The control unit 130 selects a mode. The control unit 130 may have a selection unit that selects a mode. The control unit 130 executes processing according to the selected mode. When the first mode is selected, the control unit 130 executes behavior pattern determination processing and judgment processing. When the second mode is selected, the control unit 130 does not execute the first mode.

[0113] The acquisition unit 131 acquires various types of information. The acquisition unit 131 receives information from other devices. The acquisition unit 131 receives information (detection information, etc.) collected by the collection device 50 from the collection device 50. The acquisition unit 131 receives detection information detected for each toilet space 2 from the collection device 50.

[0114] The acquisition unit 131 receives from the collecting device 50 detection information detected by a sensor or the like arranged in each toilet space 2. For example, the acquisition unit 131 receives from the collecting device 50 detection information detected by the detection sensor 21. For example, the acquisition unit 131 receives from the collecting device 50 detection information detected by the detection sensor 101. For example, the acquisition unit 131 receives from the collecting device 50 detection information detected by the detection sensor 201. For example, the acquisition unit 131 receives from the collecting device 50 detection information detected by the detection sensor 301. For example, the acquisition unit 131 receives from the collecting device 50 detection information detected by the detection sensor 401. The acquisition unit 131 receives work date and time information indicating the date and time of work in the toilet space 2 from the worker device.

[0115] The acquisition unit 131 acquires various types of information from the storage unit 120. The acquisition unit 131 acquires information to be used in processing from the storage unit 120. The acquisition unit 131 acquires information to be used in processing from the information storage unit 122.

[0116] The behavior pattern determination unit 132 performs a determination process. The behavior pattern determination unit 132 performs a determination process using various pieces of information stored in the storage unit 120. The behavior pattern determination unit 132 performs a determination process using various pieces of information acquired by the acquisition unit 131. The behavior pattern determination unit 132 determines various pieces of information to be used in the judgment process.

[0117] The behavior pattern determination unit 132 determines the behavior pattern of the entrant in the toilet space 2 based on the detection results of the detection sensor. The behavior pattern determination unit 132 determines the behavior pattern of the entrant moving between multiple management areas. The behavior pattern determination unit 132 determines the type of behavior pattern of the entrant moving between the stay area and the movement area.

[0118] The behavior pattern determination unit 132 determines the type of behavior pattern of an entrant moving from an entrance / exit area corresponding to an entrance / exit of the toilet space 2 to a movement area, or a behavior pattern of an entrant moving from an outside area provided outside the toilet space 2 to an entrance / exit area. The behavior pattern determination unit 132 determines the type of behavior pattern of an entrant using the detection time of the entrant in each area among a plurality of management areas.

[0119] The behavior pattern determination unit 132 may determine the mode using information related to the mode stored in the setting information storage unit 123. For example, the behavior pattern determination unit 132 determines the mode during a period designated for the worker to perform work in the toilet space 2 to be the second mode. For example, the behavior pattern determination unit 132 determines the mode outside of the period designated for the worker to perform work in the toilet space 2 to be the first mode. The behavior pattern determination unit 132 determines the mode during a period corresponding to the date and time of work in the toilet space 2 indicated by the work date and time information received from the worker device by the acquisition unit 131 to be the second mode.

[0120] The behavior pattern determination unit 133 performs a determination process. The behavior pattern determination unit 133 performs a determination process using various information stored in the storage unit 120. The behavior pattern determination unit 133 performs a determination process using various information acquired by the acquisition unit 131. The behavior pattern determination unit 133 performs a determination process using the behavior pattern determined by the behavior pattern determination unit 132.

[0121] The behavior pattern determination unit 133 determines whether the behavior pattern of the entrant satisfies a predetermined condition. If the behavior pattern of the entrant does not satisfy the predetermined condition, the behavior pattern determination unit 133 determines that the behavior of the entrant is abnormal or that the entrant is in an abnormal state. Based on the behavior pattern of the entrant determined by the behavior pattern determination unit 132, the behavior pattern determination unit 133 determines that the behavior pattern is that of a worker who performs work related to managing the toilet space 2 in the toilet space 2.

[0122] The behavior pattern determination unit 133 performs analysis processing. The behavior pattern determination unit 133 performs analysis processing using the detection results of the detection sensor. The behavior pattern determination unit 133 performs analysis processing using various information stored in the storage unit 120. The behavior pattern determination unit 133 performs analysis processing using various information acquired by the acquisition unit 131. The behavior pattern determination unit 133 performs analysis processing using the behavior pattern determined by the behavior pattern determination unit 132.

[0123] The behavior pattern determination unit 133 performs calculation processing. The behavior pattern determination unit 133 performs calculation processing using various information stored in the storage unit 120. The behavior pattern determination unit 133 performs calculation processing using various information acquired by the acquisition unit 131. The behavior pattern determination unit 133 performs calculation processing using the behavior pattern determined by the behavior pattern determination unit 132.

[0124] The behavior pattern determination unit 133 calculates a score. The behavior pattern determination unit 133 calculates an individual score (single score) of each behavior included in a behavior pattern. The behavior pattern determination unit 133 calculates a score (total score) of the behavior pattern. The behavior pattern determination unit 133 calculates the score using information stored in the setting information storage unit 123. The behavior pattern determination unit 133 calculates the score using score calculation information stored in the setting information storage unit 123.

[0125] The behavior pattern determination unit 133 calculates the single score of each behavior using score calculation information including a list of single score conditions that associate values ​​used as single scores with conditions for applying the values ​​as single scores. For example, when a single score condition included in the list of information is satisfied, the behavior pattern determination unit 133 adds a value corresponding to the single score condition to the single score of the behavior.

[0126] The behavior pattern determination unit 133 calculates the total score using a total score calculation function for calculating a total score from the single scores corresponding to each behavior. For example, the behavior pattern determination unit 133 calculates the total score using a total score calculation function that calculates the total score as the sum of the single scores corresponding to each behavior. For example, the behavior pattern determination unit 133 calculates the total score by adding up the single scores corresponding to each behavior. The behavior pattern determination unit 133 determines the behavior pattern based on the calculated total score.

[0127] For example, the behavior pattern determination unit 133 determines a behavior pattern based on a comparison between the total score and a threshold. For example, if the total score is less than a first threshold, the behavior pattern determination unit 133 determines that the behavior pattern is normal. For example, if the total score is equal to or greater than a first threshold and less than a second threshold, the behavior pattern determination unit 133 determines that the behavior pattern is a warning. For example, if the total score is equal to or greater than a second threshold, the behavior pattern determination unit 133 determines that the behavior pattern is abnormal. Note that the first threshold and the second threshold can be set to any values ​​as long as the second threshold is greater than the first threshold. Furthermore, the behavior pattern determination unit 133 instructs the transmission unit 134 to send an external notification according to the determination result.

[0128] The transmission unit 134 transmits information to an external information processing device. The transmission unit 134 performs an external notification by transmitting information to the external information processing device. The transmission unit 134 performs an external notification according to the determination result of the behavior pattern determination unit 133. For example, the transmission unit 134 notifies the facility manager of the facility in which the toilet space 2 is installed. In this case, the transmission unit 134 transmits information to a facility manager device used by the facility manager. For example, the transmission unit 134 notifies an external organization such as an external security company. In this case, the transmission unit 134 transmits information to an external security company device used by the external security company.

[0129] The transmission unit 134 may transmit information related to the determination result by the behavior pattern determination unit 133 to an administrator device used by an administrator who manages the toilet system 1. For example, when the behavior pattern determination unit 133 determines that a behavior pattern satisfies a predetermined condition, the transmission unit 134 transmits information indicating the toilet space 2 in which detection information indicating the behavior pattern was detected. The transmission unit 134 may also transmit information to the collection device 50. For example, the transmission unit 134 transmits information collected by the collection device 50 to the collection device 50, requesting information.

[0130] <1-6. Configuration and processing examples> Based on the above content, various configurations or examples of processing will now be described in detail. In the following, the toilet system 1 will be described as the processing entity, but each processing may be performed by any device, such as the toilet management device 100, the collection device 50, or the detection sensor, depending on the device configuration included in the toilet system 1. Note that explanations of points similar to those described above will be omitted as appropriate.

[0131] <1-6-1. Processing Overview> First, an overview of the processing in the toilet system 1 will be described with reference to Fig. 6. Fig. 6 is a conceptual diagram showing an example of the flow of processing in the toilet system.

[0132] Sensor SN1 in Fig. 6 is a sensor provided for toilet 10, and corresponds to, for example, detection sensor 101. Sensor SN2 in Fig. 6 is a sensor provided for urinal 20, and corresponds to, for example, detection sensor 201. Sensor SN3 in Fig. 6 is a sensor provided for washroom equipment 30, and corresponds to, for example, detection sensor 301. Sensor SN10 in Fig. 6 is a sensor provided for the movement area, and corresponds to, for example, detection sensor 21.

[0133] As shown in FIG. 6, the behavior pattern determination unit 132 determines a behavior pattern based on the detection results of various detection sensors such as sensors SN1, SN2, SN3, and SN10. Then, the behavior pattern judgment unit 133 judges whether the behavior pattern determined by the behavior pattern determination unit 132 satisfies a predetermined condition. For example, if the behavior pattern determination unit 133 determines that the behavior pattern satisfies the predetermined condition, it notifies the facility manager ND1 or the external security company ND2. For example, if the behavior pattern determination unit 133 determines that the behavior pattern corresponds to a warning, it notifies the facility manager ND1 by causing the transmission unit 134 to transmit information. For example, if the behavior pattern determination unit 133 determines that the behavior pattern corresponds to an abnormality, it notifies the external security company ND2 by causing the transmission unit 134 to transmit information.

[0134] <1-6-2. Example of detection range> As described above, the detection sensor may include a plurality of regions in its detection range. An example of this will be described with reference to Fig. 7. Fig. 7 is a diagram showing an example of the detection range.

[0135] In FIG. 7, the toilet booth TB1 (toilet bowl 10 11 The detection range DR11 of the detection sensor 101 provided in the urinal 20 includes two areas within the toilet booth TB1, namely, the area A1 and the area A4 adjacent to the area A1. 12 The detection range DR21 of the detection sensor 201 provided in the includes two areas: area A2 and area A4 adjacent to area A2. In this way, the detection sensor may include multiple areas in its detection range.

[0136] Furthermore, when the detection range of a detection sensor includes multiple areas, the toilet system 1 may determine, based on the detection result of the detection sensor, in which area the person is located. For example, when the detection strength of the detection sensor 101, whose detection range is DR11, is equal to or greater than a predetermined threshold, the toilet system 1 determines that the detection has detected a person in toilet booth TB1. When the detection strength of the detection sensor 101, whose detection range is DR11, is less than the predetermined threshold, the toilet system 1 determines that the detection has detected a person in area A4.

[0137] Furthermore, for example, if the detection strength of the detection sensor 201 whose detection range is detection range DR21 is equal to or greater than a predetermined threshold, the toilet system 1 determines that the detection has detected a person in area A2. Furthermore, if the detection strength of the detection sensor 201 whose detection range is detection range DR21 is less than a predetermined threshold, the toilet system 1 determines that the detection has detected a person in area A4. Note that the above is merely an example, and the toilet system 1 may use various information to determine in which area the person detected by the detection result of each detection sensor is.

[0138] <1-6-3. Processing examples according to patterns> From here, the toilet management process executed by the toilet system 1 will be described with reference to Figures 8 to 13. Figures 8 to 13 are diagrams showing an example of a determination process according to a behavior pattern.

[0139] First, the example shown in Fig. 8 will be described. For example, Fig. 8 is a diagram showing an example of a determination process according to a normal behavioral pattern. Note that in Fig. 8, the two rows of behavioral analysis and its score are omitted as in Figs. 9 to 13, but Fig. 8 may also include the two rows of behavioral analysis and its score.

[0140] The zone in the first row in Fig. 8 indicates whether the zone (area) is a stay area or a movement area, i.e., the type of the zone. The use in the second row in Fig. 8 indicates the use of the zone (area). For example, the area in the second column in Fig. 8 with the zone "movement" and the use "corridor" corresponds to area A6 of the toilet space 21.

[0141] 8 corresponds to area A5 of the toilet space 21. Furthermore, the area in the fourth column in FIG. 8, which is zone "movement" and use "free," corresponds to area A4 of the toilet space 21. Furthermore, the area in the fifth column in FIG. 8, which is zone "stay" and use "private room," corresponds to area A1 of the toilet space 21 (toilet booth TB).

[0142] 8 corresponds to area A4 of the toilet space 21. Furthermore, the area of ​​the zone "stay" and the use "washroom" in the seventh column in FIG. 8 corresponds to area A3 of the toilet space 21. Furthermore, the area of ​​the zone "movement" and the use "entrance / exit" in the eighth column in FIG. 8 corresponds to area A5 of the toilet space 21. Furthermore, the area of ​​the zone "movement" and the use "passage" in the ninth column in FIG. 8 corresponds to area A6 of the toilet space 21.

[0143] Thus, the behavior pattern in Figure 8 corresponds to normal behavior pattern #1 in Figure 2, i.e., when a person is detected moving between areas in the following order: area A6, area A5, area A4, area A1, area A4, area A3, area A5, area A6.

[0144] The detection time [s] in the third row in Figure 8 indicates the period (seconds) during which a person was detected in the corresponding area. The score [points] in the fourth row in Figure 8 indicates the score based on the corresponding detection time, i.e., the period (length) during which a person was detected in that area. The detection time [s] in the fifth row in Figure 8 indicates the period (seconds) during which a person was detected as stationary in the corresponding area. The score [points] in the sixth row in Figure 8 indicates the score based on the corresponding period (length) of stationary time. The equipment use in the seventh row in Figure 8 indicates whether or not equipment (equipment) is being used in the corresponding area. The score [points] in the eighth row in Figure 8 indicates the score based on whether or not equipment (equipment) is being used.

[0145] The single score [points] in the ninth column in Figure 8 indicates the single score based on the person's behavior in the corresponding area. The total score [points] in the tenth column in Figure 8 indicates the total score up to the corresponding area. In Figure 8, the left end corresponds to the start of detection, and the direction from left to right corresponds to the passage of time. In other words, Figure 8 shows the behavior pattern when detection starts in the zone "Movement" and purpose "Aisle" in the second column, and ends in the zone "Movement" and purpose "Aisle" in the ninth column.

[0146] In Figure 8, the toilet system 1 calculates the single score for each area as 0 because the detection time, rest time, tool use, and behavior analysis in each area do not satisfy the single score conditions. Also, the toilet system 1 calculates the total score as 0 at every stage because the single score for each area is 0.

[0147] Next, an example shown in Fig. 9 will be described. For example, Fig. 9 is a diagram showing an example of a determination process according to a behavior pattern of wandering around a zone where there is no equipment (appliance). Note that explanations of points similar to Fig. 8 will be omitted as appropriate.

[0148] The behavior analysis on the ninth line in Fig. 9 shows the analysis result of a person's behavior up to and including the behavior in the corresponding area. The score [points] on the tenth line in Fig. 9 shows the score based on the corresponding analysis result, i.e., the analysis result of a person's behavior up to and including the behavior in that area.

[0149] In FIG. 9, the toilet system 1 calculates a single score of 0 for each zone, because the detection time, stationary time, fixture use, and behavior analysis to the zone "Movement" and usage "Free" in the fourth column in FIG. 9 do not satisfy the single score conditions. On the other hand, the toilet system 1 analyzes that the person did not enter an area (area A1 to A3 in FIG. 1) where equipment (fixtures) are located, which is a zone where fixtures are located (fixture zone), until they entered the zone "Movement" and usage "Entrance / Exit" in the fifth column in FIG. 9. In this way, the toilet system 1 calculates a score based on behavior analysis of 10 because the person did not use any fixtures between the time they entered the toilet space 2 and the time they left the toilet space 2. Furthermore, the toilet system 1 uses the calculated score of 10 to calculate a total score of 10 for the stage up to the zone "Movement" and usage "Entrance / Exit" in the fifth column in FIG. 9.

[0150] For example, if the total score is less than the first threshold "10," the toilet system 1 determines that the behavior pattern at that time is normal. Furthermore, if the total score is equal to or greater than the first threshold "10" and less than the second threshold "20," the toilet system 1 determines that the behavior pattern at that time is a warning. Furthermore, if the total score is equal to or greater than the second threshold "20," the toilet system 1 determines that the behavior pattern at that time is abnormal. Note that the values ​​of the first and second thresholds described above are merely examples, and any values ​​can be set for the first and second thresholds. Since the total score up to the area of ​​the zone "Movement" and the purpose "Entrance / Exit" in the fifth column in FIG. 9 is 10, the toilet system 1 determines that the behavior pattern at the area of ​​the zone "Movement" and the purpose "Entrance / Exit" in the fifth column in FIG. 9 is a warning.

[0151] In Figure 9, the toilet system 1 calculates the single score corresponding to each area as 0 because the detection time, stationary time, equipment use, and behavior analysis for the zone "movement" and use "corridor" in the sixth column in Figure 9 do not satisfy the single score conditions.The toilet system 1 then calculates the total score for the zone "movement" and use "corridor" in the sixth column in Figure 9 as 10.Since the total score up to the zone "movement" and use "corridor" areas in the sixth column in Figure 9 is 10, the toilet system 1 determines that the behavior pattern is a warning at the point in time when the zone "movement" and use "corridor" areas in the sixth column in Figure 9 are reached.

[0152] Next, an example shown in Fig. 10 will be described. For example, Fig. 10 is a diagram showing an example of a determination process according to a behavior pattern corresponding to a warning. Note that explanations of points similar to Figs. 8 and 9 will be omitted as appropriate.

[0153] In Figure 10, the toilet system 1 calculates a single score of 0 for each area because the detection time, stationary time, equipment use, and behavior analysis up to the "Move" zone and "Free" zone in the fourth column in Figure 10 do not satisfy the single score conditions. On the other hand, the toilet system 1 analyzes that the detection time in the "Stay" zone and "Private" zone in the fifth column in Figure 10 is 1200 seconds, which satisfies the single score conditions (above a predetermined threshold). In this way, the toilet system 1 calculates a score based on behavior analysis of 10 because the person stayed in the toilet booth TB for longer than the normal usage time (e.g., average stay time). Furthermore, the toilet system 1 uses the calculated score of 10 to calculate a total score of 10 up to the "Stay" zone and "Private" zone in the fifth column in Figure 10.

[0154] Since the total score up to the area of ​​zone "stay" and purpose "private room" in the fifth column in Figure 10 is 10, the toilet system 1 judges the behavior pattern to be a warning at the point in time when it reaches the area of ​​zone "stay" and purpose "private room" in the fifth column in Figure 10.

[0155] Also, in Figure 10, the toilet system 1 calculates the single score for each area as 0, calculates the total score as 10, and judges the behavior pattern to be a warning, because the detection time, stationary time, equipment use, and behavior analysis in each area from the area of ​​zone "movement" and use "free" in the 6th column to the area of ​​zone "movement" and use "corridor" in the 9th column do not satisfy the single score conditions.

[0156] Next, an example shown in Fig. 11 will be described. For example, Fig. 11 is a diagram showing an example of a determination process according to a behavior pattern corresponding to an abnormality. Note that explanations of the same points as in Figs. 8 to 10 will be omitted as appropriate.

[0157] In Figure 11, the toilet system 1 calculates a single score of 0 for each area because the detection time, stationary time, fixture use, and behavior analysis up to the area of ​​the "Movement" zone and "Entrance / Exit" use in the third column in Figure 11 do not satisfy the single score conditions. On the other hand, the toilet system 1 analyzes that the detection time in the "Movement" zone and "Free" use in the fourth column in Figure 11 is 300 seconds, which satisfies the single score conditions (is above a predetermined threshold). Thus, because a person is located in the movement area, the toilet system 1 calculates a score based on the behavior analysis of 10. Furthermore, the toilet system 1 uses the calculated score of 10 to calculate a total score of 10 up to the area of ​​the "Movement" zone and "Free" use in the fourth column in Figure 11.

[0158] Since the total score up to the area of ​​the zone "Movement" and the area of ​​the use "Free" in the fourth column in Figure 11 is 10, the toilet system 1 judges the behavior pattern to be a warning at the point when it reaches the area of ​​the zone "Movement" and the area of ​​the use "Free" in the fourth column in Figure 11.

[0159] Furthermore, the toilet system 1 analyzes that the detection time in the area of ​​zone "stay" and usage "private room" in the fifth column in Figure 11 was 3000 seconds, which satisfies the condition for a single score (above a predetermined threshold). As such, the toilet system 1 calculates a score based on behavioral analysis of 40 because a person stayed in the toilet booth TB for a long period of time. Furthermore, using the calculated score of "40," the toilet system 1 calculates a total score of 50 (= 10 + 40) up to the area of ​​zone "stay" and usage "private room" in the fifth column in Figure 11.

[0160] Since the total score up to the area of ​​zone "stay" and use "private room" in the fifth column in Figure 11 is 50, the toilet system 1 determines that the behavior pattern is abnormal at the point when it reaches the area of ​​zone "stay" and use "private room" in the fifth column in Figure 11.

[0161] Also, in Figure 11, the toilet system 1 calculates the single score for each area as 0, the total score as 50, and the behavior pattern as abnormal, because the detection time, stationary time, equipment use, and behavior analysis in each area from the area of ​​zone "movement" and use "free" in the 6th column to the area of ​​zone "movement" and use "corridor" in the 9th column do not satisfy the single score conditions.

[0162] Next, an example shown in Fig. 12 will be described. For example, Fig. 12 is a diagram showing an example of a determination process according to a behavior pattern in which equipment (appliances) that are not used simultaneously (in one use of the toilet space 2) are used. Note that explanations of points similar to Figs. 8 to 11 will be omitted as appropriate.

[0163] In Figure 12, the toilet system 1 calculates a single score of 0 for each zone, because the detection time, stationary time, fixture use, and behavior analysis up to the "Movement" zone and "Free" zone in the sixth column in Figure 12 do not satisfy the single score conditions. On the other hand, the toilet system 1 analyzes that the toilet bowl 10 and urinal 20 in the private room (toilet booth TB) are used up to the "Stay" zone and "Urinal" zone in the seventh column in Figure 12. In this way, because the person uses the toilet bowl 10 and urinal 20 in a single use of the toilet space 2, the toilet system 1 calculates a score based on the behavior analysis of 10. Furthermore, the toilet system 1 uses the calculated score of 10 to calculate a total score of 10 for the zone up to the "Stay" zone and "Urinal" zone in the seventh column in Figure 12.

[0164] Since the total score up to the area of ​​zone "stay" and use "urinal" in the seventh column in Figure 12 is 10, the toilet system 1 determines that the behavior pattern is a warning at the point in time when it reaches the area of ​​zone "stay" and use "urinal" in the seventh column in Figure 12.

[0165] Also, in Figure 12, the toilet system 1 calculates the single score corresponding to each area as 0, the total score as 10, and the behavior pattern as a warning because the detection time, stationary time, equipment use, and behavior analysis in the area of ​​zone "movement" and use "entrance / exit" in the 8th column in Figure 12, and the area of ​​zone "movement" and use "corridor" in the 9th column in Figure 12 do not satisfy the single score conditions.

[0166] Next, an example shown in Fig. 13 will be described. For example, Fig. 13 is a diagram showing an example of a determination process according to a behavior pattern of using (entering and leaving) the same equipment (appliance) multiple times. Note that explanations of points similar to Figs. 8 to 12 will be omitted as appropriate.

[0167] In Figure 13, the toilet system 1 calculates a single score of 0 for each zone, because the detection time, stationary time, fixture use, and behavioral analysis up to the "Move" zone and "Free" zone in the sixth column in Figure 13 do not satisfy the single score conditions. Meanwhile, the toilet system 1 analyzes that the toilet basin 10 in the private room (toilet booth TB) was used multiple times up to the "Stay" zone and "Private" zone in the seventh column in Figure 13. Thus, the toilet system 1 calculates a score based on behavioral analysis of 50 because the person used the toilet basin 10 multiple times during a single use of the toilet space 2, i.e., entered and exited the toilet booth TB multiple times. Furthermore, the toilet system 1 uses the calculated score of 50 to calculate a total score of 50 for the zone up to the "Stay" zone and "Private" zone in the seventh column in Figure 13.

[0168] Since the total score up to the area of ​​zone "stay" and use "private room" in the seventh column in Figure 13 is 50, the toilet system 1 determines that the behavior pattern is abnormal at the point when it reaches the area of ​​zone "stay" and use "private room" in the seventh column in Figure 13.

[0169] Also, in Figure 13, the toilet system 1 calculates the single score corresponding to each area as 0, the total score as 50, and the behavior pattern as abnormal because the detection time, stationary time, equipment use, and behavior analysis in the area of ​​zone "movement" and use "entrance / exit" in the 8th column in Figure 13, and the area of ​​zone "movement" and use "corridor" in the 9th column in Figure 13 do not satisfy the single score conditions.

[0170] <1-6-4. Toilet Management> Next, a description will be given of a flowchart of the toilet management process executed by the toilet system 1. Note that explanations of points similar to those described above will be omitted where appropriate.

[0171] First, an example of a processing flow in the toilet management processing will be described with reference to Fig. 14. Fig. 14 is a flowchart showing an example of the toilet management processing executed by the toilet system. For example, Fig. 14 is a flowchart showing an example of the toilet management processing executed by the toilet system 1.

[0172] The toilet system 1 determines whether a person (person) is detected in the passage zone (step S101). For example, the toilet system 1 determines whether a person is located in an area (outside area) of the zone "movement" and the use "passage" such as area A6 in FIG. 1.

[0173] If the toilet system 1 detects a person in the passage zone (step S101: Yes), it executes the processes from step S102 onward. If the toilet system 1 does not detect a person in the passage zone (step S101: No), it repeats the process of step S101.

[0174] In step S102, the toilet system 1 performs an analysis process according to each zone. If the area where a person is detected is a movement zone (movement area), the toilet system 1 performs a movement zone analysis as shown in Figure 15 (step S102a). If the area where a person is detected is a stay zone (stay area), the toilet system 1 performs a stay zone analysis as shown in Figure 16 (step S102b).

[0175] Then, the toilet system 1 performs a behavior analysis as shown in Fig. 17 (step S103). Then, the toilet system 1 performs an external notification as shown in Fig. 18 (step S104). The toilet system 1 determines whether or not a person has been detected in all zones (areas) (step S105).

[0176] If the toilet system 1 has not detected a person in any of the zones (step S105: Yes), the toilet system 1 ends the process. If the toilet system 1 has not detected a person in any of the zones (step S105: No), the toilet system 1 returns to step S102 and repeats the process.

[0177] Next, an example of the processing flow of each process shown in Fig. 14 will be described. First, the movement zone analysis will be described with reference to Fig. 15. Fig. 15 is a flowchart showing an example of the analysis process. For example, Fig. 15 is a flowchart showing the movement zone analysis process executed by the toilet system 1.

[0178] The toilet system 1 determines whether the person has moved to another zone (another area) (step S201). If the toilet system 1 determines that the person has moved to another zone (step S201: Yes), it executes a process to change the zone (step S202). For example, if the toilet system 1 determines that the person has moved from area A4 to area A1, it executes a process to change the area to be processed from area A4 to area A1.

[0179] Furthermore, if the toilet system 1 determines that the user has not moved to a zone (another area) (step S201: No), it measures the duration (step S203). For example, if the toilet system 1 determines that the user is located in the same area, it counts (increases) the duration (detection time) corresponding to that area. For example, the duration (detection time) is information indicating the length of time the user stayed in that area.

[0180] The toilet system 1 also measures the stationary time (step S204). For example, when a person located in an area is stationary, the toilet system 1 counts (increases) the stationary time corresponding to that area.

[0181] Then, the toilet system 1 calculates the score (step S205). For example, the toilet system 1 calculates the score using information such as the duration and the stationary time.

[0182] Next, the stay zone analysis will be described with reference to Fig. 16. Fig. 16 is a flowchart showing an example of the analysis process. For example, Fig. 16 is a flowchart showing the stay zone analysis process executed by the toilet system 1.

[0183] The toilet system 1 determines whether the person has moved to another zone (another area) (step S301). If the toilet system 1 determines that the person has moved to another zone (step S301: Yes), it executes a process to change the zone (step S302). For example, if the toilet system 1 determines that the person has moved from area A1 to area A4, it executes a process to change the area to be processed from area A1 to area A4.

[0184] Furthermore, if the toilet system 1 determines that the user has not moved to a zone (another area) (step S301: No), it measures the duration (step S303). For example, if the toilet system 1 determines that the user is located in the same area, it counts (increases) the duration (detection time) corresponding to that area.

[0185] The toilet system 1 also measures the stationary time (step S304). For example, when a person located in an area is stationary, the toilet system 1 counts (increases) the stationary time corresponding to that area.

[0186] The toilet system 1 also measures whether or not an appliance is being used (step S305). For example, if a person located in an area is using a facility (appliance) in that area, the toilet system 1 determines that an appliance is being used in that area.

[0187] Then, the toilet system 1 calculates the score (step S306). For example, the toilet system 1 calculates the score using information such as the duration, the stationary time, and whether or not the fixture is used.

[0188] Next, behavior analysis will be described with reference to Fig. 17. Fig. 17 is a flowchart showing an example of analysis processing. For example, Fig. 17 is a flowchart showing behavior analysis processing executed by the toilet system 1.

[0189] The toilet system 1 analyzes the zones passed through so far (step S401). For example, the toilet system 1 analyzes the areas passed through before reaching the area at the time of processing.

[0190] Then, the toilet system 1 calculates the score (step S402). For example, the toilet system 1 calculates the score using information from the behavior analysis.

[0191] Next, the notification process will be described with reference to Fig. 18. Fig. 18 is a flowchart showing an example of the notification process. For example, Fig. 18 is a flowchart showing an external notification process executed by the toilet system 1.

[0192] The toilet system 1 executes a notification process according to the score value and total value of each zone (step S501). For example, the toilet system 1 issues a notification to the outside according to the individual score and total score of each zone.

[0193] Through the above-described processing, the toilet system 1 can appropriately determine whether a person is present in the toilet space. For example, to prevent criminal acts in the toilet space and ensure the psychological safety of users, it is desirable to detect suspicious individuals or abnormal behavior. However, due to privacy concerns, it is difficult to manage and monitor toilet spaces using cameras. Furthermore, even if behavioral analysis of a specific space is performed to detect suspicious behavior, it is difficult to provide accurate behavioral analysis because toilet spaces have various layouts. Therefore, the toilet system 1 zones the toilet space into multiple spaces based on use and analyzes behavior across these zones (movement between zones) to determine whether the behavior is normal or suspicious. In this way, the toilet system 1 detects suspicious individuals or abnormal behavior through behavioral analysis in multiple areas. This allows the toilet system 1 to appropriately determine whether a person present in the toilet space requires attention.

[0194] As described above, the toilet system 1 makes a determination based on a person's behavioral patterns. For example, the toilet system 1 divides multiple behavior detection areas (zones) into movement zones and stay zones, and analyzes a person's behavior in each zone to distinguish between normal and abnormal behavior. In this way, the toilet system 1 detects and determines behavior that spans a zone where movement is expected and a zone where stay is expected. While the above example mainly describes the case where a suspicious person or the like is determined, the toilet system 1 may also determine a person who is unwell, such as a person who has collapsed in the toilet space 2. In other words, the above-mentioned abnormality includes various conditions that are different from normal. Furthermore, the toilet system 1 may determine any object in the toilet space 2, not limited to determining a suspicious person or a person who is unwell, as long as the processing is applicable. For example, the toilet system 1 may be used to determine any object as long as the determination is based on a person's behavioral patterns.

[0195] As described above, the toilet system 1 also makes its determination using information on the usage status of the facilities (appliances) in the zone (e.g., the stay zone). For example, the movement zone is detected by a detection sensor that detects the status of the person in the zone. Also, the stay zone is detected by a detection sensor that detects the status of the person in the zone and the status of the appliances in the zone.

[0196] Furthermore, the toilet system 1 may make a determination using various conditions, not limited to those described above. The toilet system 1 may make a determination based on a comparison between a zone where fixtures are present (e.g., a stay zone) and a zone where fixtures are not present (e.g., a movement zone). For example, conditions for determining that behavior is not normal may be set according to the characteristics of each zone, and the toilet system 1 may make a determination using the set conditions. For example, different stay times (threshold values) may be set depending on whether a stall (e.g., toilet booth TB) or an entrance / exit, i.e., whether toilet fixtures are present or not. The toilet system 1 may also make a determination using a condition for determining that behavior is not normal if a person enters a stall (e.g., toilet booth TB) but does not use a toilet fixture.

[0197] The toilet system 1 may make a judgment based on a comparison between zones where fixtures are located (e.g., stay zones). For example, conditions for determining that behavior is not normal may be set according to the characteristics of the toilet fixtures, and the toilet system 1 may make a judgment using the set conditions. For example, different stay times (threshold values) may be set for private rooms (such as toilet booths TB) and washroom facilities.

[0198] The toilet system 1 may make a determination based on information about the layout of the zones. For example, conditions for determining abnormal behavior may be set according to the characteristics of adjacent zones, and the toilet system 1 may make a determination using the set conditions. For example, when a zone without fixtures (e.g., a movement zone) and a zone with fixtures (e.g., a stay zone) are adjacent to each other, the stay time in the zone without fixtures may be long due to waiting in line, etc. Therefore, for toilet spaces 2 where a zone without fixtures (e.g., a movement zone) and a zone with fixtures (e.g., a stay zone) are adjacent to each other, the stay time (threshold value) in the movement zone may be set long.

[0199] The toilet system 1 may make a determination based on a comparison of the uses of the zones. For example, conditions for determining that behavior is not normal may be set depending on the relationship with other zones, and the toilet system 1 may make a determination using the set conditions. For example, the toilet system 1 may make a determination using a condition that determines that using a private room (such as a toilet booth TB) and a urinal at the same time is not normal behavior when there is a private room. For example, the toilet system 1 may make a determination using a condition that determines that not using a zone with fixtures (such as a stay zone) at all is not normal behavior when there is a private room (such as a toilet booth TB) and a urinal.

[0200] The toilet system 1 may make a determination based on whether the user has returned via another zone. For example, a condition for determining that the behavior is not normal may be set based on the number of times the user has passed through another zone, and the toilet system 1 may make a determination using the set condition. For example, the toilet system 1 may make a determination using a condition for determining that the behavior is not normal, such as using different stalls (such as toilet booths TB) one after the other (such as using different stalls consecutively or using the same stall multiple times).

[0201] In this way, the toilet system 1 may use various parameters as factors for determination. For example, the toilet system 1 may make a determination using parameters other than stay time and stationary time, such as movement speed, posture, number of people, whether or not equipment is being used, the duration of equipment use, and the purpose of the equipment (toilet, hand washing, diaper changing, ostomate, nursing space, makeup touch-up, cleaning tool storage).

[0202] Furthermore, in the toilet system 1, a detection sensor that detects the status of a person and a detection sensor that detects the usage status of the fixture may be used together. As described above, in the toilet system 1, the area from which a person is detected may be distinguished based on the detection distance and detection time information of the detection sensor (human body sensor, etc.) mounted on the toilet bowl or urinal.

[0203] As described above, the toilet system 1 assigns scores (single scores, etc.) to the factors that are used as the judgment elements individually, and makes a judgment based on the sum of the scores (total score, etc.). For example, if the total score is less than the first threshold value "10," the toilet system 1 judges the behavior pattern at that time to be normal. If the total score is equal to or greater than the first threshold value "10" and less than the second threshold value "50," the toilet system 1 judges the behavior pattern at that time to be a warning. If the total score is equal to or greater than the second threshold value "50," the toilet system 1 judges the behavior pattern at that time to be abnormal.

[0204] As described above, the toilet system 1 notifies the determination result to the outside. In the above example, the notification is made by transmitting the result to the administrator device, the facility administrator device, and the external security company device, but the notification means may take various forms, such as a terminal device (such as a smartphone used by the person in charge of the notification), an administrator screen (such as a display in the managed facility), or a display sign (such as digital signage).

[0205] Furthermore, as described above, the toilet system 1 may take exception action while a worker is working, etc., to prevent erroneous determination of an abnormality. In this case, the toilet system 1 may invalidate (cancel) the determination result (condition). For example, the toilet system 1 may exclude specific people (such as cleaning personnel). In this case, the toilet system 1 may exclude specific people based on an administrator screen, an ID card, facial recognition, special operations, etc.

[0206] Furthermore, the toilet system 1 may invalidate (cancel) the determination result (condition) during cleaning. For example, the toilet system 1 may invalidate (cancel) the determination result (condition) when at least one piece of equipment (fixture) is in cleaning mode (administrator mode, etc.).

[0207] For example, the toilet system 1 may automatically invalidate (cancele) the determination result (condition). For example, the toilet system 1 may invalidate (cancele) the determination result (condition) when it detects a specific behavior. For example, the toilet system 1 may invalidate (cancele) the determination result (condition) when it detects the use of simultaneous devices in the same zone within a short period of time. This allows the toilet system 1 to prevent erroneous determination of an abnormality when cleaning is being performed, for example.

[0208] Furthermore, the toilet system 1 may invalidate (cancel) the determination result (condition) when it detects the use of equipment (fixtures) in a stall while the stall door is open. This allows the toilet system 1 to prevent erroneous determination of an abnormality when cleaning is being performed, etc. Note that the toilet system 1 may invalidate (cancel) the determination result (condition) when it detects the use of equipment (fixtures) in multiple stalls while the doors of multiple stalls are open.

[0209] Furthermore, in the toilet system 1, the determination result (condition) may be invalidated (canceled) manually. For example, the toilet system 1 may invalidate (cancele) the determination result (condition) when a specific operation is performed. For example, the toilet system 1 may invalidate (cancele) the determination result (condition) when a dedicated button is operated or an operation is performed using an administrator remote control. As described above, the toilet system 1 may invalidate (cancele) the determination result (condition) when a remote operation such as a cleaning reservation instruction is performed.

[0210] The toilet system 1 may also make a determination depending on the situation in the toilet space 2. For example, the toilet system 1 may make a determination depending on the usage status of the toilet booths TB in the toilet space 2. For example, the toilet system 1 may make a determination on the behavioral patterns of other people when one toilet booth TB (referred to as "toilet booth TBX") in the toilet space 2 is in use, i.e., when a user is using the toilet booth TBX, the toilet system 1 may determine that the behavioral patterns of other people include entering a toilet booth TB adjacent to the toilet booth TBX, staying in a movement area adjacent to the toilet booth TBX, etc., when a user is using the toilet booth TBX, and the behavioral patterns of other people include entering a toilet booth TB adjacent to the toilet booth TBX, staying in a movement area adjacent to the toilet booth TBX, etc., and may determine that the behavioral pattern corresponds to a warning or abnormality.

[0211] In this way, the toilet system 1 may make a determination by combining the usage status and behavioral patterns of the toilet space 2. As described above, the toilet system 1 may make a determination even when multiple people are located in the toilet space 2. Note that the above is only an example, and the toilet system 1 may make various determinations depending on the status of the toilet space 2 and behavioral patterns.
