Description

[Technical Field]

[0001] FIELD OF THE INVENTION Aspects of the present invention relate generally to toilet systems. [Background technology]

[0002] A toilet system is known that determines the usage status of a toilet space by combining vacancy detection devices (door sensors, motion sensors) (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-135486 Summary of the Invention [Problem to be solved by the invention]

[0004] In the toilet system disclosed in Patent Document 1, if the door is open and the toilet space is in use, there is a risk that the toilet system may be determined to be empty even when the toilet space is in use.

[0005] The aspects of the present invention have been made based on the recognition of such problems, and have an object to provide a toilet system that can detect the usage status of a toilet space with high accuracy. [Means for solving the problem]

[0006] The first invention is a toilet system comprising: an object detection sensor provided in a toilet device including a toilet or urinal connected to an AC power supply; a toilet control unit for controlling the toilet device; and a toilet management unit for managing the usage status of the toilet space in which the toilet device is installed, wherein the toilet control unit controls at least one functional unit of the toilet device based on the detection result of the object detection sensor, and the toilet management unit manages the usage status of the toilet space based on management data generated based on the detection result of the object detection sensor.

[0007] This toilet system uses an object detection sensor on the toilet unit, which is connected to an AC power source, to detect the usage status of the toilet space. This eliminates the need for battery replacement, as is required with battery-powered door sensors, thus reducing maintenance effort. Furthermore, the toilet system manages the usage status of the toilet space where the toilet unit is installed based on management data generated from the output of the object detection sensor on the toilet unit. This allows the toilet system to suppress false detections of toilet space usage and accurately understand the actual usage status of the toilet space.

[0008] A second invention is the toilet system according to the first invention, characterized in that the management data is data for indicating whether or not a human body is present in the toilet space.

[0009] This toilet system allows for the management of toilet space usage using administrative data.

[0010] The third invention is a toilet system characterized in that, in the second invention, the object detection sensor has a human body detection sensor that detects a human body present around the toilet bowl, and the management data is generated based on first human body detection information by the human body detection sensor.

[0011] According to this toilet system, for example, if the human body detection sensor is an active sensor that receives reflected light from emitted light, management data can be generated from the initial human body detection information to manage the usage status of the toilet space.

[0012] The fourth invention is a toilet system according to the second invention, characterized in that the object detection sensor includes a human body detection sensor that detects human bodies present around the toilet bowl and a seat sensor that detects a human body seated on the toilet seat of the toilet bowl, and the usage status of the toilet space is determined based on first human body detection information from the human body detection sensor and second human body detection information from the seat sensor.

[0013] According to this toilet system, for example, if the human body detection sensor is a passive sensor that detects infrared rays emitted from the user, the usage status of the toilet space can be managed from the first human body detection information from the human body detection sensor and the second human body detection information from the seating sensor.

[0014] A fifth invention is a toilet system characterized in that, in any one of the first to fourth inventions, the toilet management unit manages the usage status of the toilet space based on the management data, and the toilet control unit controls multiple functional units of the toilet device based on the detection results of the object detection sensor.

[0015] According to this toilet system, object detection sensors can detect objects and enable functions such as opening the toilet lid, warming the toilet seat, and preventing toilet bowl soiling.

[0016] The sixth invention is a toilet system characterized in that, in any one of the first to fourth inventions, the toilet control unit generates the management data based on the detection result of the object detection sensor.

[0017] With this toilet system, the toilet control unit of the toilet device generates management data, so the detection results from the object detection sensor can be used directly, improving the accuracy of determining the usage status of the toilet space.

[0018] A seventh invention is a toilet system according to any one of the first to fourth inventions, further comprising a data receiving device that receives the detection results of the object detection sensor transmitted from the toilet device, and the data receiving device generates the management data based on the detection results of the object detection sensor.

[0019] According to this toilet system, management data is generated by a data receiving device, so the usage status of the toilet space can be managed simply by receiving the detection results from object detection sensors installed in existing toilet equipment.

[0020] The eighth invention is a toilet system characterized in that, in any one of the first to fourth inventions, the toilet space is provided with a door sensor that detects the opening and closing of the entrance / exit door, and the tray management unit determines the usage status of the toilet space based on the detection results of the object detection sensor and the door sensor.

[0021] This toilet system also uses the detection results of the door sensor, which increases the accuracy of toilet space usage status. For example, if a user is standing motionless or sitting on the toilet lid to rest, there is a risk of false detection by the object detection sensor because there is no movement even when the user enters the toilet space. In such cases, if the door sensor detects that the door is closed, it can reliably detect whether the toilet space is full.

[0022] The ninth invention is a toilet system characterized in that, in any one of the first to fourth inventions, the toilet management unit controls the display mode of a display device that can be viewed by the user or manager of the toilet space, based on the management data.

[0023] This toilet system allows for monitoring the usage status of the toilet space via a display device.

[0024] A tenth invention is a toilet system characterized in that, in any one of the first to fourth inventions, the toilet management unit uses a machine learning model to determine the usage status of the toilet space in which the toilet device is installed.

[0025] This toilet system allows for accurate management of toilet space usage through machine learning models.

[0026] The eleventh invention is a toilet system that, in the first invention, further comprises a cleaning management unit which determines the cleaning order of toilet rooms having the toilet space based on the usage status of the toilet space managed by the toilet management unit, wherein the cleaning management unit determines the cleaning order from the usage status of the toilet space based on the management data.

[0027] According to this toilet system, the cleaning order of toilet rooms is determined based on the usage status of the toilet space calculated based on management data, so an efficient cleaning plan can be created based on highly accurate management data on the usage status of the toilet space.

[0028] The twelfth invention is a toilet system characterized in that, in the first invention, the system further comprises a cleaning management unit which determines the cleaning order of toilet rooms having the toilet space based on the usage status of the toilet space managed by the toilet management unit, the toilet space is provided with a door sensor which detects the opening and closing of the entrance door, and the cleaning management unit determines the cleaning order based on the usage status of the toilet space based on the management data and the detection results of the door sensor.

[0029] According to this toilet system, the cleaning order of the toilet rooms can be determined using more accurate information on the usage status of the toilet space, which also utilizes the detection results of the door sensor.

[0030] The 13th invention is a toilet system characterized in that, in the first invention, it further comprises a cleaning management unit that determines the cleaning order for cleaning the toilet room having the toilet space based on the usage status of the toilet space managed by the toilet management unit, and further comprises a transmission unit that transmits toilet usage data including the usage status of the toilet space based on the management data to an administrator terminal, and a reservation reception unit that accepts cleaning reservations from the administrator terminal.

[0031] This toilet system allows the manager (cleaner) to check toilet usage data on the manager's terminal. Furthermore, the cleaning plan allows for reservations to be made for toilets that are deemed not to require cleaning, so the manager can update the cleaning plan themselves according to the situation in the toilet room.

[0032] The 14th invention is a toilet system in accordance with the first invention, further comprising a cleaning management unit that determines the cleaning order for cleaning the toilet room having the toilet space based on the usage status of the toilet space managed by the toilet management unit, wherein the toilet space is provided with a door sensor that detects the opening and closing of the entrance / exit door, and further comprising a transmission unit that transmits toilet usage data including the management data and the usage status of the toilet space based on the detection results of the door sensor to an administrator terminal, and a reservation reception unit that accepts cleaning reservations from the administrator terminal.

[0033] According to this toilet system, the cleaning order of the toilet rooms can be determined using more accurate information on the usage status of the toilet space, which also utilizes the detection results of the door sensor. [Effects of the Invention]

[0034] According to an aspect of the present invention, a toilet system is provided that can detect the usage status of a toilet space with high accuracy. [Brief explanation of the drawings]

[Figure 2] This is a block diagram of the toilet system's control system. [Figure 3] This is a time chart showing the generation of management data performed in a toilet. [Figure 4] This is a time chart showing the generation of management data performed by the data receiving device of the toilet system according to the second embodiment. [Figure 5] This is a flowchart for calculating a cleaning plan. DETAILED DESCRIPTION OF THE INVENTION

[0036] The embodiments will be described below with reference to the drawings. In each drawing, similar components are denoted by the same reference numerals, and detailed descriptions will be omitted as appropriate. Figure 1 is a plan view showing a toilet room equipped with a toilet system according to the first embodiment of the present invention. Figure 2 is a block diagram showing the control system of the toilet system. Figure 3 is a time chart showing the generation of management data performed in the toilet.

[0037] The toilet system 1 manages the usage status (vacancy status) of each of the toilet spaces 10 to 13 in which the toilet device is installed. In this example, the toilet device is a toilet bowl 20. The toilet device may also be a urinal.

[0038] The toilet room TR is, for example, a public toilet installed in a public facility or building. As shown in FIG. 1, in this example, the toilet room TR has four toilet spaces 10-13. Note that the toilet room TR may also have one toilet space. The toilet spaces 10-13 are provided with doors 10a-13a that open and close the entrances to the toilet spaces 10-13. In other words, the toilet spaces 10-13 are toilet booths with a toilet bowl 20 installed inside.

[0039] The toilet spaces 10-13 are each provided with a door sensor 15 that detects whether the doors 10a-13a are open or closed. For example, the door sensor 15 is turned OFF when the doors 10a-13a are open, and turned ON when the doors 10a-13a are closed. The detection result of the door sensor 15 is transmitted to the toilet management device 60 via the repeater 40. The door sensor 15 is provided as needed and is not necessarily required.

[0040] The toilet 20 is a Western-style seated toilet that has a toilet bowl for receiving excrement, a toilet seat that sits on top of the bowl, and a toilet lid that covers the bowl. The toilet 20 is also connected to an AC power source (not shown). The toilet 20 has multiple electrically operated function units 22, a human body detection sensor 24 that detects users around the toilet 20, a seating sensor 26 that detects when a person is sitting on the toilet seat, and a toilet control unit 28 that controls the toilet device (toilet 20).

[0041] The functional unit 22 includes, for example, a toilet lid opening / closing function unit, a toilet seat warming function unit, and a toilet stain suppression function unit. The toilet lid opening / closing function unit automatically opens and closes the toilet lid based on, for example, human body detection by the human body detection sensor 24 described below. The toilet seat warming function unit warms the toilet seat based on, for example, human body detection by the human body detection sensor 24. The toilet stain suppression function unit discharges flush water into the toilet bowl based on, for example, human body detection by the human body detection sensor 24.

[0042] The human body detection sensor 24 is installed in the toilet bowl 20. The human body detection sensor 24 is an object detection sensor according to the present invention. The human body detection sensor 24 is, for example, a pyroelectric sensor, a microwave sensor, an infrared sensor, etc., and detects when a user enters or leaves the toilet space 10-13. The human body detection sensor 24 is, for example, a passive sensor. The detection result of the human body detection sensor 24 (first human body detection information) is transmitted to the toilet control unit 28.

[0043] As shown in Figure 1, the detection range 24a of the human body detection sensor 24 extends beyond the doors 10a to 13a. In other words, the human body detection sensor 24 also detects users crossing in front of the toilet space 10 to 13. This allows the toilet 20 to activate its functional unit 22 early based on the detection of a user.

[0044] The seat sensor 26 detects when a user sits on and leaves the toilet seat. The seat sensor 26 is installed in the toilet bowl 20. The seat sensor 26 is an object detection sensor according to the present invention. The seat sensor 26 can be, for example, a pyroelectric sensor, a microwave sensor, or an infrared sensor. Alternatively, the seat sensor 26 may be a tact switch or an electrostatic sensor installed on the toilet seat. The detection result of the seat sensor 26 (second human body detection information) is transmitted to the toilet control unit 28.

[0045] The toilet control unit 28 controls at least one functional unit 22 of the toilet device (toilet bowl 20) based on the detection results of the object detection sensor (human body detection sensor 24 or seating sensor 26). The toilet control unit 28 may also control multiple functional units 22 of the toilet device (toilet bowl 20) based on the detection results of the object detection sensor (first human body detection information and second human body detection information).

[0046] Furthermore, each toilet control unit 28 generates management data 1 to 3, which are used to indicate the usage status (occupancy status) of toilet spaces 10 to 13, based on the detection results of the object detection sensors. Management data 1 to 3 are data that indicates whether or not a person is present in toilet spaces 10 to 13. The toilet control unit 28 transmits usage information, maintenance information, and management data 1 to 3 of the toilet 20 to the toilet management device 60 via the network 50.

[0047] In addition, the toilet room TR is equipped with urinals 30 and handwashing sinks 35, etc. A hand dryer may also be installed in the toilet room TR. Note that the toilet space is not limited to that located in the toilet room TR; for example, it may also be a general toilet stall or a multi-purpose toilet.

[0048] As shown in Figure 2, the toilet system 1 includes a relay 40 capable of communicating with the outside, a toilet management device 60 connected to the toilet rooms TR (toilet spaces 10-13) via a network 50, an administrator terminal 70 for managing the toilet rooms TR, and a digital signage 80 that can check the usage status of the toilet spaces 10-13.

[0049] The repeater 40 is installed, for example, in the toilet room TR. The repeater 40 is a gateway that performs protocol conversion. The repeater 40 constitutes the data receiving device of the present invention. Note that the repeater 40 is not limited to a gateway; any communication device capable of communicating with the outside may be used.

[0050] The repeater 40 transmits a plurality of pieces of information related to the necessity of maintenance of each toilet basin 20 installed in each toilet space 10-13 and management data used for usage information of each toilet space 10-13 to the toilet management device 60 via the network 50. The repeater 40 also receives various command signals transmitted from the toilet management device 60 and transmits them to each toilet basin 20 in the toilet spaces 10-13. The repeater 40 also transmits the usage information of the toilet spaces 10-13 transmitted from the toilet management device 60 to the digital signage 80.

[0051] The network 50 is, for example, the Internet or a LAN (Local Area Network), and connects the toilet rooms TR, the toilet management device 60, and the administrator terminal 70. The network 50 may connect the toilet management device 60 and the administrator terminal 70, and the toilet management device 60 and the repeater 40, by wire, wireless, or a combination of wire and wireless. The network 50 may be any network that enables communication between the repeater 40, the toilet management device 60, and the administrator terminal 70.

[0052] The toilet management device 60 is located away from the toilet room TR. The toilet management device 60 is, for example, a cloud server and is connected to the toilet room TR (repeater 40) and the administrator terminal 70 via the network 50, and manages information about the toilet room TR. The toilet management device 60 may also be installed in the same building as the toilet room TR.

[0053] The toilet management device 60 manages, for example, a plurality of toilet rooms TR. The toilet management device 60 has a communication unit 61, a storage unit 62, and a toilet management unit 63. The toilet management device 60 manages the usage status of each of the toilet spaces 10-13.

[0054] The communication unit 61 transmits and receives signals (information) to and from the network 50. The communication unit 61 receives signals transmitted from the repeater 40 and the administrator terminal 70. The received signals are stored in the storage unit 62. The communication unit 61 also transmits signals to the repeater 40 and the administrator terminal 70 according to the instructions of the toilet management unit 63. The communication unit 61 is a transmitting unit that transmits toilet usage data to the administrator terminal 70, including the usage status of toilet spaces 10 to 13 based on management data 1 to 3. In addition to the usage status of toilet spaces 10 to 13, the toilet usage data includes maintenance information for the toilet bowl 20 and operation information for the function unit 22.

[0055] The toilet management unit 63 manages the usage status of the toilet spaces 10-13 based on the management data 1-3 generated based on the detection results of the object detection sensors. In other words, the toilet management unit 63 is a control unit that manages the usage status of the toilet spaces 10-13.

[0056] The toilet management unit 63 controls the display mode of a display device that can be viewed by users or administrators of toilet spaces 10 to 13, based on the usage status of toilet spaces 10 to 13 determined based on management data 1 to 3. This display device is the display unit 71 of the administrator terminal 70 and the digital signage 80, which will be described later. The toilet management unit 63 transmits an empty command signal or a full command signal for toilet spaces 10 to 13 to the administrator terminal 70 and the digital signage 80.

[0057] The toilet management unit 63 stores, for example, the usage status of toilet spaces 10-13 in multiple toilet rooms TR, linked to the date and time, in the memory unit 62. The toilet management unit 63 also manages the cleaning status of multiple toilet rooms TR.

[0058] The toilet management unit 63 includes a user management unit 63a, a cleaning management unit 63b, and a reservation acceptance unit 63c. Note that the user management unit 63a, the cleaning management unit 63b, and the reservation acceptance unit 63c are represented for convenience in explaining the control processes performed by the toilet management unit 63 and do not actually exist as separate entities.

[0059] The usage management unit 63a manages the usage status of the toilet spaces 10-13 based on information transmitted from the toilet rooms TR. The cleaning management unit 63b calculates a cleaning plan for the toilet rooms TR based on the usage status of the multiple toilet rooms TR stored in the memory unit 62. The reservation reception unit 63c accepts a cleaning reservation when a reservation for cleaning the toilet room TR is made from the manager terminal 70. Specific control processes of the usage management unit 63a, cleaning management unit 63b, and reservation reception unit 63c will be described later.

[0060] The manager terminal 70 is a terminal owned by a manager who manages the toilet rooms TR. The manager also includes a cleaner who cleans the toilet rooms TR. In other words, the manager terminal 70 is a mobile terminal or PC terminal owned by a manager of a building that has the toilet rooms TR or a cleaner who cleans the toilet rooms TR. The manager terminal 70 is connected to the toilet management device 60 via a network 50. The manager terminal 70 has a display unit 71 that displays various information about the toilet rooms TR, a communication unit 72 for connecting to the network 50, an operation unit 73 that can be operated by the manager, and a control unit 74 that controls the display unit 71 and the communication unit 72.

[0061] The administrator can connect to the toilet management device 60 via the communication unit 72 by operating the operation unit 73. The administrator can obtain (view) various information such as toilets 20 displayed on the display unit 71. Based on the empty command signal or full command signal for toilet spaces 10-13 transmitted from the toilet management device 60, the administrator terminal 70 displays the usage status of toilet spaces 10-13 on the display unit 71. The administrator can also operate the operation unit 73 to output various command signals from the communication unit 72 to the toilet management device 60 and toilet room TR.

[0062] The digital signage 80 is installed, for example, at the entrances and exits of toilet rooms TR or at information desks within the building. The digital signage 80 is connected, for example, to a repeater 40. The digital signage 80 may also be connected to a network 50. Based on empty command signals or full command signals for toilet spaces 10-13 transmitted from the toilet management device 60, the digital signage 80 displays the usage status of toilet spaces 10-13. The digital signage 80 also displays cleaning information for toilet rooms TR and various other information related to toilet rooms TR. Users can obtain various information about toilet rooms TR by checking the digital signage 80.

[0063] In this way, toilet system 1 enables administrators to centrally manage the usage status and maintenance requirements of toilet rooms TR by incorporating IoT (Internet of Things) technology into the toilet rooms TR. This allows administrators to access information about toilet rooms TR from a remote location.

[0064] Next, the generation of management data executed by the toilet control unit 28 will be described with reference to FIG. Figure 3 is a time chart showing the generation of management data performed in the toilet. FIG. 3 shows an example of when a user passes by the toilet space 10 and when the user uses the toilet space 10.

[0065] 3 are stored in advance in a memory unit (not shown) of the toilet 20. The first time T1, second time T2, third time T3, and fourth time T4 are set by experiment, simulation, etc., taking into consideration the layout of the toilet room TR, the size of the detection range 24a of the human body detection sensor 24, etc.

[0066] The toilet control unit 28 generates management data 1-3 based on the detection results of the human body detection sensor 24. The toilet control unit 28 generates correction data and management data 1-3 based on the first human body detection information from the human body detection sensor 24. The correction data is used, for example, when activating the functional unit 22 of the toilet bowl 20. The toilet control unit 28 continuously transmits the management data 1-3 and the detection results of the seat sensor 26 to the toilet management device 60. The toilet management unit 63 of the toilet management device 60 makes a full determination that the toilet space 10 is being used, or an empty determination that the toilet space 10 is not being used, based on the management data 1-3 and the detection results of the seat sensor 26.

[0067] When the toilet space 10 is determined to be empty, the toilet management unit 63 determines that the toilet space 10 is full if either the management data 2 or the seat sensor 26 is ON. Also, when the toilet space 10 is determined to be full, the toilet management unit 63 determines that the toilet space 10 is empty if all of the management data 1 and 3 and the seat sensor 26 are OFF.

[0068] First, a case where the user passes by the toilet space 10 will be described. In other words, a case where the user does not enter the toilet space 10 will be described.

[0069] As shown in Fig. 1, the detection range 24a of the human body detection sensor 24 extends to the outside of the door 10a of the toilet space 10. At time t1, a user enters the detection range 24a in front of the toilet space 10. This causes the human body detection sensor 24 to switch from OFF to ON. When the human body detection sensor 24 switches from OFF to ON, the toilet control unit 28 switches the correction data from OFF to ON.

[0070] Furthermore, the toilet control unit 28 measures the first time interval T1 after the human body detection sensor 24 switches from OFF to ON. The first time interval T1 is set to the time from when a user crosses in front of the toilet space 10 until they leave the detection range 24a, and is set to a few seconds (for example, 4 seconds).

[0071] At time t2, the user leaves the detection range 24a of the human body detection sensor 24. As a result, the human body detection sensor 24 switches from ON to OFF. In this case, time t2 is within a first time T1 (for example, within 4 seconds) from time t1. The toilet control unit 28 measures a second time T2 after the human body detection sensor 24 switches from ON to OFF. The second time T2 is stored in advance in the memory unit of the toilet bowl 20.

[0072] Time t3 is the time when a second time interval T2 has elapsed since time t2. The second time interval T2 is a few seconds (for example, 4 seconds). If the human body detection sensor 24 does not switch from OFF to ON within the second time interval T2, the toilet control unit 28 switches the correction data from ON to OFF at time t3.

[0073] Entry into the toilet space 10 (transition from empty to full) is determined based on the management data 2 and the detection results of the seat sensor 26. As shown in Figure 3, when a user passes by the toilet space 10, the management data 2 remains OFF even if the human body detection sensor 24 detects the user. This causes the toilet management unit 63 to determine that the toilet space 10 is empty.

[0074] The toilet management unit 63 transmits information that the toilet space 10 is empty to the digital signage 80 via the network 50 and the repeater 40. The toilet management unit 63 also transmits information that the toilet space 10 is empty from the network 50 to the administrator terminal 70. The digital signage 80 and the administrator terminal 70 display, for example, that the toilet space 10 is "empty." The usage management unit 63a of the toilet management device 60 also manages the empty state of the toilet space 10 by linking it to the date and time.

[0075] Next, a case where a user uses the toilet space 10 will be described. That is, a use determination from when the user enters the toilet space 10 until when the user leaves the toilet space 10 will be described.

[0076] Time t11 is the time when the user enters detection range 24a of human body detection sensor 24. At time t11, the same control process as at time t1 is executed. At time t12, first time T1 has passed. When first time T1 has passed since human body detection sensor 24 was switched from OFF to ON, and human body detection sensor 24 continues to be in the ON state, toilet control unit 28 switches management data 1 to 3 from OFF to ON. Toilet control unit 28 transmits management data 1 to 3 and the detection result of seat sensor 26 to toilet management unit 63.

[0077] The toilet management unit 63 switches the empty state of the toilet space 10 to a full state based on the switching of the management data 2 from OFF to ON. In other words, the toilet management unit 63 determines that a user has entered the toilet space 10 if the human body detection sensor 24 continues to detect a user for a first time T1 after detecting the user. In addition, the toilet control unit 28 starts measuring a third time T3 from time t12. The third time T3 is pre-stored in the memory unit of the toilet bowl 20.

[0078] The toilet management unit 63 transmits information that the toilet space 10 is full to the digital signage 80 via the repeater 40. The toilet management unit 63 also transmits information that the toilet space 10 is full to the administrator terminal 70. The digital signage 80 and the administrator terminal 70 display, for example, that the toilet space 10 is "full." The usage management unit 63a of the toilet management device 60 also manages the fullness state of the toilet space 10 by linking it to the date and time.

[0079] Time t13 is the time when a third time T3 has elapsed since time t12. The third time T3 is several tens of seconds (for example, 10 seconds). If the human body detection sensor 24 does not switch from ON to OFF and then ON again between the time when the management data 1 is switched from OFF to ON and the time when the third time T3 has elapsed, the toilet control unit 28 switches the management data 3 from ON to OFF. The management data 3 is data generated to stabilize the data at the time of entry into the toilet rooms 10-13.

[0080] At time t14, the user sits on the toilet seat. This causes the seat sensor 26 to switch from OFF to ON. When the user is seated on the toilet seat and not moving, the human body detection sensor 24 switches from ON to OFF. The toilet control unit 28 switches management data 1 from ON to OFF. In addition, the toilet control unit 28 begins measuring the second time T2 and the fourth time T4 after the human body detection sensor 24 switches from ON to OFF. The fourth time T4 is pre-stored in the memory unit of the toilet bowl 20.

[0081] At time t14, management data 1 and 3 are OFF, but the seat sensor 26 is ON. Therefore, the toilet management unit 63 continues to determine that the toilet space 10 is full.

[0082] Time t15 is the time when the second time period T2 has elapsed since time t14. The toilet control unit 28 switches the correction data from ON to OFF if the human body detection sensor 24 does not switch from OFF to ON during the second time period T2.

[0083] Time t16 is the time when a fourth time T4 has elapsed since time t14. The fourth time T4 is several seconds (e.g., 8 seconds). If the human body detection sensor 24 does not switch from OFF to ON during the fourth time T4, the toilet control unit 28 switches the management data 2 from ON to OFF.

[0084] At time t17, the user sitting on the toilet seat moves. As a result, human body detection sensor 24 detects the user's movement and switches from OFF to ON. Toilet control unit 28 switches the correction data from OFF to ON. Furthermore, when human body detection sensor 24 switches from OFF to ON, toilet control unit 28 starts measuring first time T1.

[0085] Time t18 is the time when first time T1 has passed. When first time T1 has passed since human body detection sensor 24 was switched from OFF to ON, and human body detection sensor 24 continues to be in the ON state, toilet control unit 28 switches management data 1-3 from OFF to ON. In addition, toilet control unit 28 starts measuring third time T3 from time t18.

[0086] At time t19, the user leaves the toilet seat, causing the seat sensor 26 to switch from ON to OFF. The human body detection sensor 24 continues to detect the user's movement and therefore remains ON.

[0087] Time t20 is the time when the third time T3 has elapsed since time t18. If human body detection sensor 24 switches from ON to OFF and then ON again within the period from when management data 1 switches from OFF to ON until the third time T3 has elapsed, toilet control unit 28 switches management data 3 from ON to OFF.

[0088] At time t21, the user has left the toilet space 10 and is out of the detection range 24a of the human body detection sensor 24. As a result, the human body detection sensor 24 switches from ON to OFF. The toilet control unit 28 switches management data 1 from ON to OFF. The toilet control unit 28 also starts measuring the second time period T2 and the fourth time period T4 after the human body detection sensor 24 switches from ON to OFF.

[0089] At time t21, the management data 1 and 3 are OFF, and the seat sensor 26 is also OFF. Therefore, the toilet management unit 63 switches the toilet space 10 from a full state to an empty state.

[0090] The toilet management unit 63 transmits to the digital signage 80 via the relay unit 40 that the toilet space 10 is vacant. The toilet management unit 63 also transmits to the administrator terminal 70 that the toilet space 10 is vacant. The digital signage 80 and the administrator terminal 70 display, for example, that the toilet space 10 is "vacant". In addition, the usage management unit 63a of the toilet management device 60 manages the vacancy status of the toilet space 10 in association with the date and time.

[0091] Time t22 is the time when the second time T2 has elapsed since time t21. If the human body detection sensor 24 does not switch from OFF to ON during the second time T2, the toilet control unit 28 switches the correction data from ON to OFF.

[0092] Time t23 is the time when a fourth time T4 has elapsed since time t21. If human body detection sensor 24 does not switch from OFF to ON during fourth time T4, toilet control unit 28 switches management data 2 from ON to OFF.

[0093] For example, if the detection result of the human body detection sensor 24 is used as it is to determine the usage status of the toilet space 10, there is a risk that the usage status of the toilet space 10 will not be determined appropriately.

[0094] In response to this, the toilet control unit 28 generates management data 1-3 based on the detection results of the human body detection sensor 24. Then, the toilet management unit 63 determines the usage status of the toilet space 10 from the management data 1-3. The toilet management device 60 manages the usage status of the toilet spaces 10-13. This allows the toilet system 1 to detect the usage status of the toilet spaces 10-13 with high accuracy. Furthermore, since the human body detection sensor 24 is connected to an AC power source, maintenance work can be reduced.

[0095] Next, a case where the management data 1 to 3 are generated by a data receiving device (repeater 40 or toilet management device 60) will be described with reference to Fig. 4. In this example, a case where the management data 1 to 3 are generated by the toilet management unit 63 of the toilet management device 60 will be described. FIG. 4 is a time chart showing the generation of management data executed by the data receiving device of the toilet system according to the second embodiment.

[0096] The toilet control unit 28 generates correction data from the detection results of the human body detection sensor 24. The generation of the correction data (switching between ON and OFF) is the same as in the first embodiment described above. Then, the toilet control unit 28 transmits the correction data to the toilet management device 60. The toilet control unit 28 also transmits the detection results of the seat sensor 26 to the toilet management device 60. In this case, the correction data is transmitted to the toilet management device 60 so that the toilet management device 60 can accurately confirm the status of users entering the toilet spaces 10 to 13. The toilet management device 60 generates management data 1 to 3 from the correction data.

[0097] The second time T2 shown in Figure 4 is stored in the memory unit of the toilet bowl 20. The third time T3, fifth time T5, and sixth time T6 shown in Figure 4 are also stored in advance in the memory unit 62 of the toilet management device 60. The third time T3, fifth time T5, and sixth time T6 are set by experiment, simulation, etc., taking into consideration the layout of the toilet room TR, the size of the detection range 24a of the human body detection sensor 24, etc.

[0098] The usage management unit 63a of the toilet management unit 63 generates management data 1 to 3 from the corrected data. When the toilet space 10 is determined to be empty, the usage management unit 63a determines that the toilet space 10 is full if either the management data 2 or the seat sensor 26 is ON. Furthermore, when the toilet space 10 is determined to be full, the usage management unit 63a determines that the toilet space 10 is empty if all of the management data 1 and 3 and the seat sensor 26 are OFF.

[0099] The usage management unit 63a starts measuring a fifth time T5 after the correction data is switched from OFF to ON. The fifth time T5 corresponds to the first time T1 in the first embodiment and is longer than the first time T1 (e.g., 8 seconds). As shown in Fig. 4, when the fifth time T5 has elapsed, if the correction data remains ON, the usage management unit 63a switches the management data 1 to 3 from OFF to ON.

[0100] When the user passes by the toilet space 10, the correction data is switched from ON to OFF at time t31, which is shorter than the fifth time T5 after the correction data was switched from OFF to ON. Therefore, the usage management unit 63a keeps the management data 1 to 3 OFF even after the fifth time T5 has passed. Since the management data 2 is OFF and the detection result of the seat sensor 26 is also OFF (leaving the seat), the usage management unit 63a determines that the toilet space 10 is empty.

[0101] On the other hand, when the user uses the toilet space 10, the correction data continues to be ON at time t41, which is the fifth time T5 since the correction data was switched from OFF to ON. Therefore, the usage management unit 63a switches the management data 1 to 3 from OFF to ON at time t41, which is the fifth time T5.

[0102] At time t41, management data 2 is ON. Therefore, the user management unit 63a determines that the toilet space 10 is full because management data 2 is ON. The toilet management unit 63 transmits to the administrator terminal 70 and the digital signage 80 that the toilet space 10 has switched from empty to full. As a result, the administrator terminal 70 and the digital signage 80 display that the toilet space 10 is "full".

[0103] The period from time t42 to time t43 is the time when the user is seated on the toilet seat. Therefore, the seat sensor 26 is ON during the period from time t42 to time t43. The usage management unit 63a maintains the full state because the seat sensor 26 is ON during the period from time t42 to time t43, even if both management data 1 and 3 are OFF.

[0104] At time t44, the correction data is switched from ON to OFF. As a result, the usage management unit 63a switches the management data 1 from ON to OFF. The usage management unit 63a also starts measuring a sixth time T6 from time t44. The sixth time T6 corresponds to the fourth time T4 in the first embodiment and is several seconds (for example, 4 seconds).

[0105] At time t44, management data 1 and 3 are OFF, and the seat sensor 26 is also OFF. Therefore, the usage management unit 63a determines that the toilet space 10 has switched from full to empty. The toilet management unit 63 transmits to the administrator terminal 70 and the digital signage 80 that the toilet space 10 has switched from full to empty. As a result, the administrator terminal 70 and the digital signage 80 display that the toilet space 10 is "empty".

[0106] Time t45 is the time when a sixth time T6 has elapsed since time t44. When the sixth time T6 has elapsed since the correction data was turned OFF, the usage management unit 63a switches the management data 2 from ON to OFF.

[0107] The toilet system 1 according to this second embodiment also has the same effects and advantages as the toilet system 1 of the first embodiment. In the second embodiment, for example, the usage status of each toilet space 10 to 13 can be determined by a cloud server. Therefore, the usage status of each toilet space 10 to 13 can be accurately managed using the human body detection sensor 24 and seating sensor 26 that are pre-installed in each toilet bowl 20. In other words, according to the second embodiment, the usage status of the toilet spaces 10 to 13 can be managed without making any modifications to the toilet bowl 20.

[0108] In addition, the detection result of the door sensor 15 may be added to the determination of the occupancy status of the toilet spaces 10-13 in the above-described embodiment. For example, when the door sensor 15 detects a closed state, the occupancy status of the toilet spaces 10-13 is determined to be full regardless of the detection results of the human body detection sensor 24 and the seating sensor 26.

[0109] This allows the system to maintain a "full" state even if, for example, the user is standing still in the toilet space 10 without sitting on the toilet seat, or sitting still on the toilet lid. On the other hand, if the user is using the toilet space 10 with the door sensor 15 open, the system can determine that the toilet is full based on the detection results of the human body detection sensor 24 and the seating sensor 26.

[0110] In the above-described embodiment, an example was described in which the management data 1 to 3 were generated using the first time T1 to the sixth time T6 as the detection results of the human body detection sensor 24. However, the toilet management unit 63 may use a machine learning model to determine the usage status of the toilet spaces 10 to 13 in which the toilet device (toilet bowl 20) is installed.

[0111] For example, the storage unit 62 of the toilet management device 60 stores multiple models in advance. This model prepares several typical layouts of toilet spaces 10 to 13 in toilet room TR, and models the relationship between the detection results of the human body detection sensor 24 and the seating sensor 26 in each layout, the usage status of toilet spaces 10 to 13, and the management data 1 to 3 that should be generated from the detection results of the human body detection sensor 24 and the seating sensor 26 to match the usage status of toilet spaces 10 to 13, for each typical layout. The toilet management unit 63 generates the management data 1 to 3 based on the detection results of the human body detection sensor 24 and the seating sensor 26, and the selected model.

[0112] Alternatively, instead of pre-storing multiple models in the memory unit 62, a model may be constructed for each toilet room TR. In this case, door sensors 15 are installed in the toilet spaces 10-13 of the toilet room TR for a predetermined period of time. The toilet management device 60 then acquires the detection results of the human body detection sensor 24 and the seating sensor 26, the detection results of the door sensor 15, and the usage status of the toilet space determined from the detection results of the door sensor 15. From the acquired data, the toilet management device 60 constructs a model that associates the detection results of the human body detection sensor 24 and the seating sensor 26 in each toilet space 10-13, the usage status of the toilet spaces 10-13, and management data 1-3 that should be generated from the detection results of the human body detection sensor 24 and the seating sensor 26 to match the usage status of the toilet spaces 10-13. After that, the door sensors 15 are removed from the toilet spaces 10-13. The toilet management device 60 generates management data 1-3 based on the detection results of the human body detection sensor 24 and the constructed model.

[0113] Next, a cleaning plan for a toilet TR calculated by the toilet management device 60 when there are multiple toilets TR in a building will be described with reference to FIG. FIG. 5 is a flow diagram for calculating a cleaning schedule.

[0114] The toilet management unit 63 of the toilet management device 60 has a cleaning management unit 63b that determines the cleaning order of toilet rooms TR in the building, and a reservation reception unit 63c that receives cleaning reservations for toilet rooms TR from the manager terminal 70. The cleaning management unit 63b determines the cleaning order of toilet rooms TR in the building based on the usage status of toilet spaces 10 to 13 of each toilet room TR stored in the memory unit 62.

[0115] The control processing program shown in Figure 5 is pre-stored in the memory unit 62 of the toilet management device 60. In Figure 5, each step is indicated by "S", for example, "Step 1" is indicated by "S1".

[0116] In S1, a standard cleaning plan is acquired. For example, the memory unit 62 stores the layout of the building. The cleaning management unit 63b determines the cleaning order based on, for example, the distance from the staff room where the manager (cleaner) waits to each toilet TR. As an example, the cleaning management unit 63b calculates a cleaning plan in order starting with the toilet TR closest to the staff room. Note that the cleaning management unit 63b may acquire a cleaning plan drawn up by the manager from the manager's terminal 70, for example.

[0117] In S2, the number of times of use for each toilet space in each toilet room TR in each time period is calculated for the past week. That is, the cleaning management unit 63b calculates the number of times each toilet space 10-13 has been used in each time period from the usage status of the toilet spaces 10-13 in each toilet room TR stored in the memory unit 62. The cleaning management unit 63b calculates the number of times the toilet spaces 10-13 have switched from an empty state to a full state as the number of times the toilet spaces 10-13 have been used.

[0118] In S3, the number of times each toilet room has been used is compared. That is, the cleaning management unit 63b compares the number of times each toilet room TR has been used, calculated from the full state of the toilet spaces 10 to 13. In the next S4, the cleaning priority of the toilet room with the most frequent use is increased. That is, the cleaning management unit 63b arranges the toilet rooms TR in the building in order of the number of times they have been used.

[0119] In S5, the cleaning plan is updated by changing the cleaning order according to priority. That is, the cleaning management unit 63b changes the standard cleaning plan from S1 to a cleaning order according to priority. The cleaning management unit 63b may also incorporate the congestion level of each toilet room TR during each time period, calculated in S2, into updating the cleaning plan. That is, the cleaning management unit 63b may prioritize the cleaning order of toilet rooms TR with high usage, and also calculate the cleaning plan considering time periods when toilet rooms TR are expected to be less congested.

[0120] In S6, the system determines whether there is a cleaning reservation for any toilet room from the administrator terminal. For example, the administrator may receive a report from a user that toilet room TR is dirty. In such a case, the administrator operates the administrator terminal 70 to make a cleaning reservation for the toilet room TR in question. The reservation reception unit 63c of the toilet management device 60 receives the cleaning reservation for toilet room TR transmitted from the administrator terminal 70.

[0121] Then, if the system determines in S6 that "YES" is true, meaning that the administrator terminal 70 has a cleaning reservation for any toilet room TR, the process proceeds to S7. On the other hand, if the system determines in S6 that "NO" is true, meaning that the administrator terminal 70 has no cleaning reservation for any toilet room TR, the process ends. In this case, the toilet management unit 63 transmits the cleaning plan updated in S5 from the communication unit 61 to the administrator terminal 70. The updated cleaning plan is displayed on the display unit 71 of the administrator terminal 70. This allows the toilet system 1 to efficiently clean multiple toilet rooms TR within the building.

[0122] In S7, the cleaning priority of toilets with cleaning reservations is increased. That is, the cleaning management unit 63b moves up the cleaning order of toilets TR that have been received by the reservation reception unit 63c. In the next S8, the cleaning order is changed according to the priority and the cleaning plan is updated. That is, the cleaning management unit 63b updates the cleaning plan updated in S5 again to a cleaning plan that takes cleaning reservations into account, and then the process ends.

[0123] In this case, the toilet management unit 63 transmits the cleaning plan updated again in S8 from the communication unit 61 to the manager terminal 70. The cleaning plan that takes the cleaning reservation into consideration is displayed on the display unit 71 of the manager terminal 70. This allows the toilet system 1 to efficiently clean multiple toilet rooms TR in the building and to quickly clean toilet rooms TR that have become soiled.

[0124] Furthermore, the cleaning management department 63b may re-update the cleaning plan updated in S5 and S8 based on the current usage status of toilet spaces 10-13. For example, the cleaning management department 63b may re-update the cleaning plan by lowering the priority of toilet rooms TR that are currently crowded.

[0125] In the above-described embodiment, an example has been described in which the usage status of the toilet spaces 10-13 is determined based on the management data 1-3 generated from the detection results of the human body detection sensor 24 and the detection results of the seating sensor 26. However, the present invention is not limited to this, and for example, the usage status of the toilet spaces 10-13 may be determined only based on the management data 1-3 generated from the detection results of the human body detection sensor 24.

[0126] Furthermore, in the above-described second embodiment, an example has been described in which the toilet management device 60 generates the management data 1 to 3 and determines the usage status of the toilet spaces 10 to 13. However, the present invention is not limited to this, and for example, the management data 1 to 3 may be generated by the repeater 40. Furthermore, the usage status of the toilet rooms 10 to 13 may be determined by the repeater 40.

[0127] In the above-described embodiment, the human body detection sensor 24 is a passive sensor. However, the present invention is not limited to this. For example, the human body detection sensor may be an active sensor that receives reflected light from emitted light. An active sensor can detect a user who is seated on the toilet seat and not moving. Therefore, by using the human body detection sensor 24 as an active sensor, the usage status of the toilet spaces 10-13 can be determined using only the management data 1-3.
