Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above-described conventional technology, toilet devices may not be efficiently managed. For example, in the conventional technology, the lifespan of individual toilet devices is managed, but in a site where a plurality of the same toilet devices are provided in a toilet space, when there is a bias in the use of the toilet devices, there is a possibility that replacement work may be required only for specific toilet devices. Further, when replacement work is performed, it becomes difficult to manage the toilet devices. Thus, there is room for improvement in the method of managing toilet devices.

[0005] An object of the disclosed embodiments is to provide a device management system in a toilet space that can efficiently manage toilet devices.

Means for Solving the Problems

[0006] A device management system in a toilet space according to one embodiment is a device management system for managing the usage status of a plurality of devices installed in and to be managed in a toilet space, comprising: a first management means for managing installation location information relating to the installation location of the device in the toilet space together with device identification information assigned to each device; and a second management means for managing the usage status of each device, wherein the plurality of devices include a first device and a second device whose installation locations can be exchanged with each other, and when the installation locations of the first device and the second device are changed, the first management means changes the installation location information associated with the respective device identification information of the first device and the second device, while the second management means manages the usage status of the first device and the second device before and after the installation location change in an associated manner.

[0007] According to a device management system within a toilet space according to one embodiment, the installation location and usage status of toilet equipment such as heated toilet seats installed in each toilet booth in the toilet space are managed in association with each other. Information on changes in the installation location of toilet equipment, such as when there is an imbalance in the use of toilet equipment in a particular toilet booth, is also managed in association with the installation location. As a result, even when the location is changed, the usage status of toilet equipment in each toilet booth after the change can be managed, aiming to equalize the lifespan of toilet equipment in the toilet space. In other words, by managing installation location information, including change history, and usage status in association with each other, it becomes possible to efficiently manage toilet equipment.

[0008] In one embodiment of the device management system in a toilet space, the first management means has a storage unit that stores history information prior to the change of installation location.

[0009] According to one embodiment of the device management system for a toilet space, by storing historical information before the installation location was changed, it is possible to store information necessary to predict the future usage frequency of toilet booths and devices. Furthermore, the stored historical information can be used to allow administrators to intuitively understand the usage status and frequency of toilet booths and devices by graphing them.

[0010] In a device management system within a toilet space according to one embodiment, the history information includes the installation location before the change in installation location and the cumulative number of times the installation location has been changed.

[0011] According to a device management system within a toilet space according to one embodiment of the system, the history information includes the installation location before the change of installation location and the cumulative number of times the installation location has been changed. This allows for the storage of information necessary to predict, for example, the future usage frequency of toilet booths and devices. Furthermore, the stored history information can be used to graph the usage status and frequency of toilet booths and devices, allowing administrators to intuitively understand the situation.

[0012] In one embodiment of the device management system in a toilet space, when the first device is replaced with a newly introduced third device, the first management means updates the installation location information relating to the installation location of the first device to associate it with the device identification information of the third device, and the second management means updates the usage status of the third device relating to the installation location of the first device.

[0013] According to a device management system in a toilet space that is part of one embodiment, when a device is replaced with a new one, the information of the device's installation location is associated with the identification information of the new device, and the usage status of the new device is updated by inheriting the information on the frequency of use of the installation location. This makes it possible to respond even when a new device is installed, and enables efficient management of toilet equipment.

[0014] A device management system in a toilet space according to one embodiment of the system notifies that it is time to change the installation location when predetermined conditions are met.

[0015] According to a device management system in a toilet space that embodies one embodiment, by notifying the timing of a change in installation location when predetermined conditions are met, the administrator can quickly plan a change in the installation location of toilet equipment and make the change at an appropriate time. This equalizes the lifespan of multiple toilet devices in the toilet space and enables efficient management of toilet equipment.

[0016] In a device management system for a toilet space according to one embodiment, the first device and the second device are bidet toilet seats installed in different toilet booths, each toilet booth has a door opening / closing detection means for detecting the opening and closing of the toilet booth door, the first management means manages the device identification information of the bidet toilet seat in association with the door opening / closing detection means installed in the toilet booth where the bidet toilet seat is installed, and the second management means calculates the usage status based on the door opening / closing information from the door opening / closing detection means.

[0017] According to a device management system in a toilet space that is part of one embodiment, by detecting door opening and closing and calculating usage status, it is possible to indirectly grasp the usage status of the toilet seat from the door opening and closing means, even when it is not possible to obtain usage status directly from the toilet equipment, thereby enabling efficient management of the toilet equipment.

[0018] In a device management system within a toilet space according to one embodiment, the toilet space comprises a first space and a second space different from the first space, and the first device and the second device are provided in the different spaces.

[0019] According to the device management system in the toilet space according to one aspect of the embodiment, for example, in the same facility, devices installed in adjacent male and female toilet spaces or toilet spaces provided for each floor can be exchanged with each other. Therefore, it is possible to equalize the lifespan of the devices as a whole facility, and efficient management of toilet equipment throughout the facility can be performed.

[0020] The device management system in the toilet space according to one aspect of the embodiment further includes an output means for outputting at least one or more of the information managed by the first management means and the information managed by the second management means to an external system.

[0021] According to the device management system in the toilet space according to one aspect of the embodiment, by outputting information such as installation location information including change history and usage status to an external system, for example, in a full-empty system, a screen display reflecting the actual usage status can be performed, enabling cooperation with the external system.

Advantages of the Invention

[0022] According to one aspect of the embodiment, efficient management of toilet equipment can be performed.

[0024] Hereinafter, with reference to the attached drawings, an embodiment of the device management system 1 for a toilet space, which is an example of a device management system for a toilet space disclosed in this application, will be described in detail. In the first embodiment, a process for managing usage status in light of changes in the installation location of devices will be described. In the second embodiment, the usage status of each device will be calculated from door opening and closing information detected by a door opening and closing detection sensor installed in the toilet booth. In the third embodiment, a process for outputting information such as installation location information and usage status to an external system will be described. In the following embodiments, "toilet" may refer to a toilet seat device, or a toilet seat device and a toilet bowl. A toilet booth refers to a partitioned space within a toilet space such as a toilet booth. Furthermore, this invention is not limited to the embodiments shown below.

[0025] <First Embodiment> 〔overview〕 First, an overview of the information processing performed in the device management system 1 in the toilet space (see Figure 3) according to the first embodiment will be described with reference to Figures 1 and 2. The device management system 1 in the toilet space described in this embodiment is a device management system that manages the usage status of multiple devices installed in the toilet space and subject to management, such as toilet seats and hand dryers. Figures 1 and 2 are diagrams illustrating an overview of the processing performed by the device management system 1 in the toilet space. Figure 1 shows that there are differences in the frequency of use of each toilet booth in the toilet space. Figure 2 schematically shows the toilet replacement in the toilet space shown in Figure 1.

[0026] In the example shown in Figure 1(1), toilet booths 1 to 4 are installed in a toilet space, with toilet A in toilet booth 1, toilet B in toilet booth 2, toilet C in toilet booth 3, and toilet D in toilet booth 4. In the example in Figure 1(1), toilet A has been used 50,000 times, and toilet D has been used 10,000 times. As shown in Figure 1(2), a graph with the number of uses on the vertical axis and time on the horizontal axis, the usage frequency of each toilet in Figure 1(1) remains constant. In this situation, as time passes, differences in the number of uses will appear according to the usage frequency of each toilet. For example, it is expected that toilet A will need to be replaced more often than toilet D. Therefore, from the perspective of device management, it is desirable to equalize the lifespan of each toilet device.

[0027] For this reason, changes or swaps in the locations of toilets may be made to equalize the lifespan of each toilet. For example, from the situation shown in Figure 1(1), as shown in Figure 2, the location of toilet A is changed to toilet booth 4 and the location of toilet D is changed to toilet booth 1, thereby swapping the positions of toilet A and toilet D.

[0028] In situations where the toilet locations are not rearranged, the relationship between the toilet booth and the toilet is fixed, making it possible to manage devices by considering the usage frequency of the toilet booth as the usage frequency of the toilet. However, when the toilet locations are rearranged as shown in Figure 2, the relationship between the toilet booth and the toilet is disrupted, making it impossible to consider the usage frequency of the toilet booth as the usage frequency of the toilet, thus making device management difficult.

[0029] Therefore, the device management system 1 in the toilet space manages the usage status of each device while associating the identification information of each device with the information of its installation location. When the installation location of a device is changed, the system changes the installation location information associated with the device identification information and manages the usage status of the device before and after the change in installation location in a correlated manner.

[0030] As a result, the device management system 1 within the toilet space manages the installation location and usage status of toilet equipment installed in each toilet booth within the toilet space, and also manages information after changes in the installation location of toilet equipment, such as when there is an imbalance in the use of toilet equipment in a particular toilet booth, linking it to the installation location. Therefore, even if the location is changed, the device management system 1 within the toilet space can manage the usage status of toilet equipment in each toilet booth after the change, aiming to equalize the lifespan of toilet equipment in the toilet space. In other words, the device management system 1 within the toilet space enables efficient management of toilet equipment by managing installation location information, including change history, and usage status in an interconnected manner.

[0031] [Configuration of the device management system within the toilet space] Next, with reference to Figure 3, an example of the configuration of the device management system 1 in the toilet space according to the first embodiment will be described. Figure 3 is a diagram showing an example of the configuration of the device management system 1 in the toilet space according to the first embodiment. As shown in Figure 3, the device management system 1 in the toilet space includes a device management device 100 that manages the usage status of devices and toilet equipment 200 which are devices installed in the toilet space. Note that the configuration of the management system 1 shown in Figure 3 is merely an example, and any configuration can be adopted as long as the device management system 1 in the toilet space can perform the desired processing.

[0032] The device management device 100 is an information processing device that manages the installation location and usage status of toilet equipment 200 in association with each other. For example, the device management device 100 manages the past installation locations and past usage status of the target toilet equipment 200 in association with each other. The device management device 100 may also be a cloud server (server device).

[0033] Toilet equipment 200 is a device installed in the toilet space, such as a toilet seat (heated toilet seat) or a hand dryer. A device is defined as a device having a predetermined function, such as a toilet seat or hand dryer. The following describes an example where toilet equipment 200 is a toilet seat. Toilet equipment 200 is a device that sits on top of a toilet bowl, which has a bowl section for receiving waste, and functions as a toilet seat. Toilet equipment 200 detects the use of the toilet by a user. For example, toilet equipment 200 detects the user's seating using seating sensors such as infrared sensors or pressure sensors.

[0034] Furthermore, the toilet equipment 200 detects a user's entry into the toilet booth where the toilet is installed using entry detection sensors such as microwave sensors and infrared sensors. The toilet equipment 200 also detects user operation of the toilet using operation sensors such as pressure sensors. Furthermore, the toilet equipment 200 detects user defecation and urination using defecation and urination detection sensors such as microwave sensors. In addition, the toilet equipment 200 detects user use of the toilet based on the power supply status, such as the power supply time and power supply interval of the device.

[0035] The toilet equipment 200 can communicate with an external information processing device such as a device management device 100 via a communication unit implemented by a communication device, communication circuit, etc. For example, the toilet equipment 200 transmits information to the device management device 100 that allows for the understanding of the frequency of toilet use by the user, such as detection information. The toilet equipment 200 may be detachably attached to the toilet bowl, or it may be attached so as to be integrated with the toilet bowl. For example, if the toilet equipment 200 is attached so as to be integrated with the toilet bowl, the toilet has the toilet equipment 200 and the toilet bowl.

[0036] [Example of device management system configuration] Next, with reference to Figure 4, an example of the functional configuration of the device management device 100 according to the first embodiment will be described. Figure 4 is a diagram showing an example of the functional configuration of the device management device 100 according to the first embodiment. The device management device 100 shown in Figure 4 has a communication unit 110, a storage unit 120, and a control unit 130. The device management device 100 may also have an input unit (e.g., a keyboard or mouse) that accepts various operations from the administrator of the device management device 100, and a display unit (e.g., a liquid crystal display) for displaying various information.

[0037] The communication unit 110 is implemented, for example, by a communication device, a communication circuit, etc. The communication unit 110 is connected to any network such as the Internet by wired or wireless connection and transmits and receives information with an external information processing device. The communication unit 210 may be connected to an external information processing device in a communicative manner by a predetermined wireless communication function such as Wi-Fi. For example, the communication unit 110 transmits and receives information with other devices such as toilet equipment 200. In this way, the communication unit 110 is a connection means to which the device management device 100 is connected in a communicative manner via a predetermined network.

[0038] The storage unit 120 is implemented by, for example, semiconductor memory elements such as RAM (Random Access Memory) and flash memory, or storage devices such as hard disks and optical discs. For example, the storage unit 220 is a computer-readable recording medium that non-temporarily records data used by information processing programs. As shown in Figure 4, the storage unit 120 has a device information storage unit 121, an installation location storage unit 122, and a usage status storage unit 123. The individual parts of the storage unit 120 will be described below.

[0039] The device information storage unit 121 stores information about the device. For example, the device information storage unit 121 stores information such as the device identification number, type, and start date of use. Here, with reference to Figure 5, an example of the information stored by the device information storage unit 121 will be explained. Figure 5 is a table diagram showing an example of the information stored by the device information storage unit 121 according to the first embodiment. For example, as shown in Figure 5, the device information storage unit 121 stores information such as "device number, type, model number, installation date and time, and remarks" associated with each other.

[0040] The "device number" stored here indicates a number that identifies the device. "Type" indicates the type of device. The type of device is not particularly limited as long as it is a replaceable device installed in the toilet space, such as a heated toilet seat or a hand dryer. "Installation start date and time" indicates the date and time the device was installed. "Notes" indicates notes about the device. Notes may include, for example, past repair information for the device.

[0041] To illustrate with a concrete example using the second row of Figure 5, for instance, the device information storage unit 121 stores information such as, "Device A's heated toilet seat has model number ******, was installed on ** / ** / 2014, and had a ○○ part replaced in 2022." In other words, the device information storage unit 121 stores basic information about each device.

[0042] The installation location storage unit 122 stores the installation location of the device. For example, the installation location storage unit 122 stores information about the installation location of each device. Here, with reference to Figure 6, an example of the information stored by the installation location storage unit 122 will be explained. Figure 6 is a table diagram showing an example of the information stored by the installation location storage unit 122 according to the first embodiment. For example, as shown in Figure 6, the installation location storage unit 122 stores information such as "device number, toilet booth number, cumulative number of changes, toilet booth number before change, cumulative number of changes" associated with each other.

[0043] The "device number" stored here indicates the device number. The "toilet booth number" indicates the number of the toilet booth where the device is installed. The "toilet booth number before change" indicates the number of the toilet booth where the device was installed before the location change. The "cumulative number of changes" indicates the cumulative number of times the location of the device in question has been changed.

[0044] To illustrate with a specific example using Figure 6(1), for instance, the installation location memory unit 122 stores information such as "device A is installed in toilet booth 1, device B is installed in toilet booth 2, device C is installed in toilet booth 3, and device D is installed in toilet booth 4." In this way, the installation location memory unit 122 stores information about the installation location of each device.

[0045] Furthermore, the installation location memory unit 122 stores history information. For example, the installation location memory unit 122 stores history information before the installation location change. The history information includes the installation location before the installation location change and the cumulative number of installation location changes. To illustrate a specific example using Figure 6(2) as an example, the installation location memory unit 122 stores information such as "device A was installed in toilet booth 1 before the location change, and the cumulative number of changes is 1; devices B and C have not had their locations changed; and device D was installed in toilet booth 4 before the location change, and the cumulative number of changes is 1." In other words, the installation location memory unit 122 stores information on installation location changes for each device.

[0046] The usage status storage unit 123 stores the usage status of the toilet booths. For example, the usage status storage unit 123 stores information such as the identification number of the toilet booth and its usage status. Here, an example of the information stored by the usage status storage unit 123 will be explained with reference to Figure 7. Figure 7 is a table diagram showing an example of the information stored by the usage status storage unit 123 according to the first embodiment. For example, as shown in Figure 7, the usage status storage unit 123 stores information such as "toilet booth, usage period, usage status, and usage status up to the present" associated with each other.

[0047] The "toilet booth number" stored here indicates the identification number of the toilet booth. The "usage period" indicates a predetermined period, such as at the time of installation or the first rotation. The "usage status" indicates the usage status for each period. Usage status includes, for example, the number of times used and the frequency of use. The "usage status to date" shows the total usage status. To illustrate with a specific example using Figure 7, the usage status storage unit 123 stores the information that "toilet booth 1 was used 15,000 times before the rotation, and has been used 8,000 times from the time of the rotation until now, for a total of 23,000 uses to date." In other words, the usage status storage unit 123 stores information on the usage status of each toilet booth up to date.

[0048] The control unit 130 may be, for example, an information processing device (control device) that controls various configurations and processes. The control unit 130 may have, for example, a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit), and may be implemented by executing a program stored inside the control unit 130 using RAM or the like as a working area. Alternatively, the control unit 130 may have, for example, an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

[0049] As shown in Figure 4, the control unit 130 includes an acquisition unit 131, a first management unit 132, and a second management unit 133, and realizes or executes the information processing functions and operations described below. Note that the internal configuration of the control unit 130 is not limited to the configuration shown in Figure 4, and other configurations are also acceptable as long as they perform the information processing described later.

[0050] The acquisition unit 131 acquires information regarding the frequency of device use. For example, the acquisition unit 131 acquires information regarding the frequency of device use from the toilet equipment 200 or a sensor provided by the toilet equipment 200. Here, information regarding the frequency of device use includes, for example, detection results such as entering the toilet booth, approaching the toilet, sitting on the toilet equipment 200 provided by the toilet, defecation, operation, power-on time, and power-on intervals. Information regarding the frequency of device use may include date and time information at the time of detection and information about the detected device. For example, the acquisition unit 131 acquires information from the seating sensor A provided by toilet A that states, "User seating was detected on ** / ** / 2014 at **:**."

[0051] Furthermore, the acquisition unit 131 acquires device identification information and device installation location information. For example, the acquisition unit 131 acquires device identification information and device installation location information by receiving input from an administrator or an external device.

[0052] The first management unit 132 manages the device identification information assigned to each device, along with location information regarding the device's installation location within the toilet space. Furthermore, if the installation locations of the first and second devices are changed, the first management unit 132 changes the location information associated with the respective device identification information of the first and second devices.

[0053] Now, with reference to Figure 8, a change in the installation location of the device according to the embodiment will be described. Figure 8 is a diagram showing an example of changing the installation location of the device according to the embodiment. For example, the installation location of the device may be changed within a single toilet space, as shown in Figure 8(1), or between a men's toilet space and a women's toilet space on the same floor, as shown in Figure 8(2), or between toilet spaces on different floors within the same building, as shown in Figure 8(3).

[0054] In other words, the toilet space has a first space and a second space different from the first space, and the first device and the second device are installed in different spaces, and the installation locations of the first device and the second device may be changed. Thus, the change (exchange, swap, rotation) of the installation locations of the first device and the second device in this embodiment can be performed not only within a single toilet space, but also between multiple toilet spaces.

[0055] Next, the processing by the first management unit 132 will be explained with reference to Figure 9. Figure 9 is a diagram showing an example of management processing by the first management unit 132 according to the embodiment, relating to the change of installation locations of existing devices. Figure 9 shows the information of devices installed in each toilet booth number for each period. "Toilet booth number" indicates the toilet booth number. "Device number" indicates the number of the device installed in the toilet booth during each period shown in the second row. "Installation time", "1st rotation time", "2nd rotation time", "2nd rotation time", and "4th rotation time" indicate the respective periods. For example, "Installation time" in Figure 9 shows the state of the devices at the time of installation, indicating that device A is installed in toilet booth 1, device B is installed in toilet booth 2, device C is installed in toilet booth 3, and device D is installed in toilet booth 4.

[0056] In the situation shown in Figure 9 during installation, if the installation locations of toilet A in toilet booth 1 and toilet D in toilet booth 4 are swapped, the first control unit 132 changes the installation location information associated with the first device, toilet A, to toilet booth 4, and changes the installation location information associated with the second device, toilet D, to toilet booth 1, as shown in Figure 9 during the first rotation. In other words, when the installation locations of devices are swapped, the first control unit 132 associates the swapped installation location information with each device.

[0057] As an alternative example, the first management unit 132 can handle not only the swapping of positions of already installed devices, but also the exchange of already installed devices with newly introduced devices. For example, when the first device is replaced by a newly introduced third device, the first management unit 132 updates the installation location information of the first device to associate it with the device identification information of the third device. Here, a specific example will be explained with reference to Figure 10. Figure 10 is a diagram showing an example of management processing related to the change of installation location with a new device by the first management unit 132 according to the first embodiment. Figure 10(1) schematically shows the replacement with a newly introduced toilet. Figure 10(2) is a table diagram with the same configuration as Figure 9, showing the information of devices installed in each toilet booth number for each period.

[0058] For example, as shown in Figure 10(1), when replacing toilet A, which has been used 150,000 times in the same toilet space, with a newly introduced toilet E, the first management unit 132 updates the toilet booth 1, which is the installation location information of toilet A, the first device, by associating it with toilet E, the third device, as shown in Figure 10(2) during the first rotation. In other words, when a device is replaced, the first management unit 132 associates the installation location information of the device before replacement with the installation location information of the new device after replacement.

[0059] Furthermore, the first management unit 132 may also have an installation location storage unit 122 that functions as a first management means and stores historical information prior to the change of installation location.

[0060] The second management unit 133 manages the usage status of each device. Furthermore, when the installation locations of the first and second devices are changed, the second management unit 133 manages the usage status of the first and second devices before and after the installation location change by relating them together. Now, referring to Figure 11, the management process by the second management unit 133 will be explained. Figure 11 is a diagram showing an example of the management process by the second management unit 133 regarding changes in the installation locations of existing devices according to the first embodiment. Figure 11(1) is a table diagram with the same configuration as Figure 9. Figure 11(2) shows the usage status of Figure 7 with added device information items, referring to Figure 11(1).

[0061] For example, suppose the first device is toilet A and the second device is toilet D, with toilet A installed in toilet booth 1 and toilet D installed in toilet booth 4, and the installation locations of toilet A and toilet D are swapped. In this case, the second management unit 133 manages the usage information of toilet A and toilet D before and after the installation location change by associating it, as shown in the fifth column "Device Number" of Figure 11(2).

[0062] To give a specific example, the second management unit 133 first refers to the information that, as shown in Figure 11(1) during installation, toilet A was installed in toilet booth 1, toilet B in toilet booth 2, toilet C in toilet booth 3, and toilet D in toilet booth 4. Furthermore, as shown in Figure 11(1) during the first rotation, the second management unit 133 refers to the information that, during the first rotation, toilet D was installed in toilet booth 1, toilet B in toilet booth 2, toilet C in toilet booth 3, and toilet A in toilet booth 4.

[0063] Then, the second management unit 133 uses the referenced information to set the device number for toilet booth 1 to "A" before rotation (at the time of installation) and to "D" after rotation (at the time of the first rotation), as shown in Figure 11(2). Similarly, for toilet booth 4, it sets the device number to "D" before rotation and to "A" after rotation.

[0064] In other words, the second management unit 133 manages usage information by referring to the information on the change history of the installation location of each toilet equipment 200 in Figure 11(1) and associating it with the device number information corresponding to the usage period in Figure 11(2).

[0065] In this way, by managing the usage status of devices before and after changes in their installation location in a correlated manner, it becomes possible to manage the usage status of each device and each toilet booth. For example, even if devices are replaced within a single toilet space or across multiple toilet spaces, it becomes possible to understand the usage status of each device and each toilet booth during each replacement period.

[0066] Next, referring to Figure 12, we will explain the effects of managing the usage status of the first and second devices before and after the change of installation location in an correlated manner. Figure 12 is a diagram showing an example of the effects of the device management system 1 in a toilet space. Figure 12(1) shows the number of times each toilet has been used as an example of the usage status of each toilet equipment 200. "Device number" indicates the identification number of the device. "At installation" and "1st rotation" to "4th rotation" indicate the period. "Period until rotation" indicates the number of times it has been used during the period in question. "Cumulative" indicates the cumulative number of times it has been used from installation to the period in question. Figure 12(2) shows the number of times each toilet booth has been used as an example of the usage status of each toilet booth. "Toilet booth number" indicates the identification number of the toilet booth. The rest is the same as in Figure 12(1).

[0067] For example, by the second management unit 133 managing the usage status of the first and second devices before and after the change in an interconnected manner, it is possible to obtain information such as "For toilet A, number of uses during the period until rotation at the time of installation: 0 times, cumulative number of uses: 0 times, number of uses during the period until rotation in the first rotation: 15,000 times, cumulative number of uses: 15,000 times, number of uses during the period until rotation in the second rotation: 5,000 times, cumulative number of uses: 20,000 times, number of uses during the period until rotation in the third rotation: 7,000 times, cumulative number of uses: 27,000 times, number of uses during the period until rotation in the fourth rotation: 4,000 times, cumulative number of uses: 31,000 times" for "device number = A" in Figure 12(1). In other words, by the second management unit 133 managing the usage status of the first and second devices before and after the change in an interconnected manner, it becomes possible to grasp the usage status of each device up to that point, even when devices are replaced.

[0068] Similarly, for "Toilet Booth = 1" in Figure 12(2), information such as "For Toilet Booth 1, number of uses during the period until rotation at the time of installation: 0, cumulative number of uses: 0, number of uses during the period until rotation in the 1st rotation: 15,000, cumulative number of uses: 15,000, number of uses during the period until rotation in the 2nd rotation: 16,000, cumulative number of uses: 31,000, number of uses during the period until rotation in the 3rd rotation: 15,000, cumulative number of uses: 46,000, number of uses during the period until rotation in the 4th rotation: 10,000, cumulative number of uses: 56,000" can be obtained. In other words, by the second management unit 133 managing the usage status of the first and second devices before and after the change in relation to each other, it becomes possible to grasp the usage status of each toilet booth up to that point, even when there is a device replacement.

[0069] Next, assuming that it is now possible to understand the usage status of each device and each toilet booth even when devices are replaced, the effects of storing historical information will be explained with reference to Figures 13 to 15. Figures 13 to 15 are diagrams illustrating the effects of the device management system 1 in the toilet space. Figure 13 shows, for example, the trend of predicted usage of toilet booth 1 (1) and the trend of predicted usage of toilet booth 4 (2), created from the usage status of toilet booths shown in Figure 7, as graphs with elapsed time on the horizontal axis and number of uses on the vertical axis. In Figure 13, the solid lines represent actual usage status, and the dotted lines represent predicted usage.

[0070] If we know the number of times each toilet stall has been used to date, we can predict future usage trends, as shown in Figure 13, by, for example, assuming that usage will continue at a similar level to past usage based on the toilet stall usage information shown in Figure 7.

[0071] Next, Figure 14 shows, for example, the trends in usage of toilet A (1), toilet D (2), toilet booth 1 (3), and toilet booth 4 (4), which were created from the usage status of each toilet booth in Figure 12(1) and the usage status of each toilet in Figure 12(2), as graphs with elapsed time on the horizontal axis and number of uses on the vertical axis. The solid lines in Figure 14 represent usage status, and the dotted lines represent usage predictions.

[0072] The device management system 1 within the toilet space manages usage data before and after a change in installation location, thereby calculating the number of uses for each toilet and toilet booth even when the installation location is changed. For example, based on the usage data for each toilet and toilet booth as shown in Figures 12(1) and 12(2), it becomes possible to verify the effects of changing the installation location.

[0073] For example, the effectiveness of rotating toilet equipment 200 can be measured by comparing how much the frequency of use has been leveled out. To give a specific example, if the locations of toilet A, which was installed in toilet booth 1, and toilet D, which was installed in toilet booth 4, are swapped, the usage status of toilet A after its location change (Figure 14(1)) can be compared with the usage status of toilet D after its location change (Figure 14(2)). This makes it possible to confirm the effect of leveling out the usage status of the toilet equipment 200 among themselves.

[0074] Furthermore, it becomes possible to measure the effectiveness by comparing the predicted usage of the installed toilet booths with the actual usage of the installed toilet equipment 200 after rotation. To give a specific example, if the locations of toilet A, which was installed in toilet booth 1, and toilet D, which was installed in toilet booth 4, are swapped, as shown in Figure 14, it is possible to compare the predicted usage of toilet booth 1 after the change in location (Figure 14(3)) with the actual usage of toilet A, which was installed in toilet booth 1 (Figure 14(1)). This makes it possible to confirm the effect that the number of times toilet A was used was reduced compared to when the location was not changed.

[0075] Next, Figure 15 shows the trends in usage of toilet A (1), toilet D (2), toilet booth 1 (3), and toilet booth 4 (4) in graphs with elapsed time on the horizontal axis and number of uses on the vertical axis.

[0076] As an alternative example, it becomes possible to measure the effectiveness by comparing the usage status of the installed toilet booths with the usage status after the rotation of the installed devices. To give a specific example, if the locations of toilet A, which was installed in toilet booth 1, and toilet D, which was installed in toilet booth 4, are swapped, as shown in Figure 15, the usage status of toilet booth 1 after the change in location (Figure 15(3)) is compared with the usage status of toilet A, which was installed in toilet booth 1 (Figure 15(1)). This makes it possible to confirm the effect that the number of times toilet A was used was reduced compared to when the location was not changed.

[0077] In addition to the effects explained in Figures 13 to 15, other effects include, for example, enabling facility managers with toilet spaces to intuitively understand the impact of toilet equipment rotation on usage and the necessity of rotating the toilet equipment 200. Furthermore, based on predicted future usage, it becomes possible to propose rotation before the usage differences between toilet equipment 200 become too large.

[0078] Let's explain the processing of the second management unit 133 again. As an alternative example, the second management unit 133 can handle not only the swapping of positions between already installed devices, but also the exchange of an already installed device with a newly introduced device. For example, if the first device is replaced with a newly introduced third device, the second management unit 133 updates the usage status of the third device regarding the installation location of the first device. Now, with reference to Figure 16, let's explain the management processing by the second management unit 133. Figure 16 is a diagram showing an example of the management processing by the second management unit 133 regarding the change of installation location for a new device according to the first embodiment. Figure 16(1) is a table diagram with the same configuration as Figure 10(2). Figure 16(2) shows the usage status of Figure 7 updated with reference to Figure 16(1).

[0079] For example, suppose toilet A is installed in toilet booth 1, and toilet A, the first device, is replaced with a newly introduced third device, toilet E. In this case, the second management unit 133 manages the usage information of toilet A and toilet E before and after the change of installation location, as shown in the "device number" in Figure 16(2).

[0080] To give a specific example, the second management unit 133 first refers to the information that, as shown in Figure 16(1) during installation, toilet A was installed in toilet booth 1, toilet B in toilet booth 2, toilet C in toilet booth 3, and toilet D in toilet booth 4. Furthermore, as shown in Figure 16(1) during the first rotation, the second management unit 133 refers to the information that, during the first rotation, toilet E was installed in toilet booth 1, toilet B in toilet booth 2, toilet C in toilet booth 3, and toilet D in toilet booth 4.

[0081] Then, the second management unit 133 uses the referenced information to set the device number corresponding to before rotation (at the time of installation) for toilet booth 1 to "A" and the device number corresponding to after rotation (at the time of the first rotation), as shown in Figure 16(2). In other words, the second management unit 133 refers to the information in Figure 16(1) and associates it with the device number information corresponding to the usage period in Figure 16(2) to manage the usage status information.

[0082] The notification unit 134 notifies that it is time to change the installation location. For example, the notification unit 134 transmits information to the terminal device that it is time to change the installation location of the heated toilet seat when predetermined conditions are met. These predetermined conditions include, for example, when a predetermined period of time has elapsed while the usage frequency of each toilet booth is within a predetermined range, when the difference in the number of times each toilet booth is used exceeds a predetermined value, when the difference in the number of times each device is used exceeds a predetermined value, or when the difference in the number of times the device with the fewest uses and the device with the most uses exceeds a predetermined threshold.

[0083] Here, the notification process by the notification unit 134 will be explained with reference to Figure 17. Figure 17 is a diagram showing an example of the notification process by the notification unit 134 according to the first embodiment. In Figure 17, the changes in the usage status of toilet booth 1 (1) and the changes in the usage status of toilet booth 2 (2) are shown in a graph with elapsed time on the horizontal axis and the number of uses on the vertical axis. For example, as shown in Figure 17, when the difference in the number of uses of toilet booth 1 (1) and toilet booth 2 (2) exceeds a certain level, the notification unit 134 displays the information "It's time to swap the devices in toilet booth 1 and toilet booth 2" on the screen of a terminal device such as a PC or smartphone that manages the devices.

[0084] 〔flowchart〕 Next, with reference to Figure 18, the processing flow of the device management system 1 in the toilet space according to the first embodiment will be described. Figure 18 is a flowchart showing an example of the processing flow performed by the device management system 1 in the toilet space according to the first embodiment. Each step in the flowchart may be rearranged within a non-inconsistent range, and some steps may not be performed.

[0085] First, the device management system 1 in the toilet space acquires information regarding the frequency of device use (step S101). Next, the device management system 1 in the toilet space determines whether predetermined conditions are met, such as the difference in the number of times the toilet booths are used exceeding a predetermined value (step S102). If the device management system 1 in the toilet space determines that the predetermined conditions are not met (step S102; No), it repeats the process in step S102. On the other hand, if the device management system 1 in the toilet space determines that the predetermined conditions are met (step S102; Yes), it notifies, for example, a terminal device that manages the devices, that it is time to change the installation location (step S103).

[0086] Next, the device management system 1 in the toilet space determines whether or not the device's installation location has been changed (step S104). For example, the device management system 1 in the toilet space determines whether or not the device's installation location has been changed by receiving input information regarding the change in the device's installation location from the user or an external system. If the device management system 1 in the toilet space determines that the device's installation location has not been changed (step S104; No), it performs the process of step S104 again.

[0087] Meanwhile, if the device management system 1 in the toilet space determines that the installation location of a device has been changed (step S104; Yes), it changes the installation location information associated with the device identification information (step S105). Subsequently, the device management system 1 in the toilet space manages the usage status of the device before and after the installation location change by relating them together (step S106). Then, the device management system 1 in the toilet space terminates its processing.

[0088] <Second Embodiment> In the first embodiment, an example was described in which the device management system 1 in the toilet space manages the usage status of devices in light of changes in their installation location, and acquires the usage status of each device using various sensors provided by the installed toilet equipment 200. However, the embodiment is not limited to this. For example, the device management system 1 in the toilet space can also calculate the usage status of each device from the door opening and closing information detected by a door opening and closing detection sensor installed in the toilet booth. This point will be explained in the second embodiment. Note that the contents described in the first embodiment will be omitted as appropriate.

[0089] [Configuration of the device management system within the toilet space] Next, with reference to Figure 19, an example of the configuration of the device management system 1 in the toilet space according to the second embodiment will be described. Figure 19 is a diagram showing an example of the configuration of the device management system 1 in the toilet space according to the second embodiment. As shown in Figure 19, the device management system 1 in the toilet space differs from the first embodiment in that, in addition to the system configuration of Figure 3, it further includes a usage detection sensor 300, which is a sensor that detects the use of the toilet equipment 200.

[0090] Furthermore, in the second embodiment, as in the first embodiment, the toilet equipment 200 is a heated bidet toilet seat. For example, the first device and the second device, which are toilet equipment 200, are heated bidet toilet seats installed in different toilet booths.

[0091] The usage detection sensor 300 is a sensor for detecting information regarding the frequency of use of the toilet equipment 200. The usage detection sensor 300 is associated with the toilet equipment 200, and the information regarding the frequency of use detected by the usage detection sensor 300 is stored as information regarding the frequency of use of the associated toilet equipment 200. The usage detection sensor 300 is, for example, a door open / close detection sensor installed on the door of a toilet booth. The door open / close detection sensor may be, for example, a magnetic switch installed on the door so that the switch is off when the door is closed and on when the door is open.

[0092] Here, with reference to Figure 20, an example of the usage detection sensor 300 according to the second embodiment will be described. Figure 20 is a diagram showing an example of the usage detection sensor 300 according to the second embodiment. For example, as shown in Figure 20, the door opening / closing sensor is installed on the door portion of a toilet booth in which the toilet equipment 200 is installed, and detects the opening and closing of the toilet booth door. This makes it possible to obtain information regarding the frequency of use of the toilet equipment 200, even if, for example, the toilet equipment 200 is not equipped with various sensors such as a seating sensor, or if the various sensors equipped with the toilet equipment 200 are not functioning due to malfunction or the like.

[0093] [Example of device management system configuration] The acquisition unit 131 acquires information regarding the frequency of use of the toilet equipment 200 from the usage detection sensor 300. For example, the acquisition unit 131 acquires information about door opening and closing from the door opening / closing detection sensor. Here, the door opening / closing information may include information about the sensor that detected the door opening and closing, and the date and time the door was opened or closed. For example, the acquisition unit 131 acquires information from the door opening / closing detection sensor 1 that the door was opened at ** / ** / 2024 at **:**.

[0094] The first management unit 132 manages the device identification information of the heated toilet seat by associating it with the door open / close detection sensor installed in the toilet booth where the heated toilet seat is installed. For example, the first management unit 132 stores information associating the toilet equipment 200 with the usage detection sensor 300. Now, referring to Figure 21, the processing by the first management unit 132 will be explained. Figure 21 is a diagram showing an example of management processing by the first management unit 132 according to the second embodiment. For example, as shown in Figure 21, the first management unit 132 stores information associating "door open / close sensor number, device number," etc. Here, the stored "door open / close detection sensor number" indicates the number of the door open / close detection sensor. The "device number" indicates the number of the device. For example, as shown in Figure 21, the first management unit 132 manages the door open / close detection sensor 1 with toilet A, the door open / close detection sensor 2 with toilet B, the door open / close detection sensor 3 with toilet C, and the door open / close detection sensor 4 with toilet D by associating them.

[0095] In this way, by the first management unit 132 managing the device identification information in association with the door open / close detection sensor, the door open / close detection sensor can detect the opening and closing of the door as information regarding the frequency of use of the associated toilet equipment 200.

[0096] Management processing associated with device identification information and door open / close detection sensors is performed in the same way as management processing associated with device identification information and installation location information. For example, if the installation locations of the first and second devices are changed, the first management unit 132 changes the information of the door open / close detection sensors associated with the device identification information of the first and second devices, respectively. More specifically, suppose that toilet A has a door open / close detection sensor 1 associated with it and toilet C has a door open / close detection sensor 3 associated with it, and the installation locations of toilet A and toilet C are swapped. In this case, the first management unit 132 updates the information by associating toilet A with the door open / close detection sensor 3 and toilet C with the door open / close detection sensor 1.

[0097] The second management unit 133 calculates the usage status of the first and second devices based on the door opening and closing information from the door opening and closing detection sensor. For example, the second management unit 133 counts the opening and closing of a door detected by the door opening and closing detection sensor as the use of the device associated with the door opening and closing detection sensor. More specifically, if the door opening and closing of a door is detected twice by the door opening and closing detection sensor 1, the second management unit 133 counts that device A, which is associated with the door opening and closing detection sensor 1, has been used once.

[0098] The above counting method assumes that when the toilet equipment 200 inside the toilet booth is used, the door is opened and closed once upon entry and once upon exit. The correspondence between the information detected by the door opening / closing detection sensor and the usage status of the toilet equipment 200 inside the toilet booth can be freely changed depending on the purpose, such as removing noise information or accurately understanding the usage status.

[0099] Here, with reference to Figure 22, the management process of the second management unit 133 when a device is replaced will be explained. Figure 22 is a diagram showing an example of the management process by the second management unit 133 according to the second embodiment. In Figure 22, the items "door open / close detection sensor number" and "device number" are the same as in Figure 21. "Usage status before rotation" shows the usage status of the toilet equipment 200 as detected by the door open / close detection sensor during the period before the rotation. "Usage status after rotation" shows the usage status of the toilet equipment 200 as detected by the door open / close detection sensor during the period after the rotation. "Usage status to date" shows the total usage status of the toilet equipment 200 before and after the rotation.

[0100] Specifically, Figure 22(1) shows that before the rotation, door open / close detection sensor 1 was associated with toilet A, door open / close detection sensor 2 with toilet B, and door open / close detection sensor 3 with toilet C, with toilet A being used 10,000 times, toilet B being used 5,000 times, and toilet C being used 1,000 times. Furthermore, Figure 22(2) shows that after the rotation, door open / close detection sensor 1 was associated with toilet C, door open / close detection sensor 2 with toilet B, and door open / close detection sensor 3 with toilet A, with toilet C being used 10,000 times, toilet B being used 5,000 times, and toilet A being used 1,000 times.

[0101] The second management unit 133 combines the correspondence between the door opening / closing detection sensors and the toilet equipment 200 before and after the rotation shown in Figures 22(1) and (2), and the usage status of each toilet equipment 200, to calculate the usage status of each toilet equipment 200 to date, as shown in Figure 22(3), with Toilet A: 11,000 times (10,000 times + 1,000 times), Toilet B: 10,000 times (5,000 times + 5,000 times), and Toilet C: 11,000 times (1,000 times + 10,000 times).

[0102] In this way, the device management system 1 in the toilet space calculates the usage status using the detection results from the door opening / closing detection sensor. This allows for indirect understanding of the usage status of each toilet device 200, even when it is not possible to obtain usage status directly from the toilet devices 200, thus enabling efficient management of the toilet devices 200.

[0103] <Third Embodiment> In the first and second embodiments, the process by which the device management system 1 in the toilet space manages usage status in light of changes in the installation location of devices was described. However, the device management system 1 in the toilet space can also output information such as installation location information and usage status to an external system. This point will be explained in the third embodiment. Note that the contents described in the first embodiment will be omitted as appropriate.

[0104] [Example of device management system configuration] Referring to Figure 23, an example of the functional configuration of the device management device 100 according to the third embodiment will be described. Figure 23 is a diagram showing an example of the functional configuration of the device management device 100 according to the third embodiment. As shown in Figure 23, the device management device 100 in the third embodiment differs from the first embodiment in that, in addition to the functional configuration in Figure 4, it also has an output unit 135.

[0105] The output unit 135 outputs at least one piece of information managed by the first management unit 132 and the second management unit 133 to an external system. The output processing by the output unit 135 will now be explained with reference to Figure 24. Figure 24 is a diagram showing an example of the output processing by the output unit 135 according to the third embodiment. For example, the output unit 135 outputs the identification information of the device managed by the first management unit 132, the installation location of the device, and the usage status of the device managed by the second management unit 133 to the occupancy system. For example, the output unit 135 outputs the information that "Toilet A, installed in toilet booth 1 in the men's toilet space on the 3rd floor of facility ***, is currently in use" to the occupancy system.

[0106] As an alternative example, the output unit 135 outputs to the facility management system the identification information of the device managed by the first management unit 132 and the information of the device's installation location. More specifically, the output unit 135 outputs to the occupancy system the information that "the new location of toilet A, which was installed in toilet booth 1 in the men's toilet space on the 3rd floor of facility ***, is toilet booth 4 in the same toilet space."

[0107] In this way, the device management system 1 within the toilet space outputs information such as installation location information including the change history of toilet equipment 200 and usage status to an external system, enabling integration with external systems, for example, by displaying a screen that reflects the actual usage status of toilet equipment 200 in a occupancy system.

[0108] 〔flowchart〕 Next, with reference to Figure 25, the processing flow of the device management system 1 in the toilet space according to the third embodiment will be described. Figure 25 is a flowchart showing an example of the processing flow performed by the device management system 1 in the toilet space according to the third embodiment. Each step in the flowchart may be rearranged within a reasonable range, and some steps may not be performed.

[0109] First, the device management system 1 in the toilet space acquires information regarding the frequency of device use (step S101). Then, the device management system 1 in the toilet space outputs the information it manages to an external system (step S202). For example, the device management system 1 in the toilet space outputs at least one of the pieces of information managed by the first management unit 132 and the second management unit 133 to the external system. After that, the device management system 1 in the toilet space terminates its processing.

[0110] 〔others〕 In the embodiments described above, processing for devices installed in toilet spaces was illustrated as an example, but the invention is not limited to this. For example, the device management system can be applied to devices installed in water-related spaces such as shower rooms and hot water supply rooms. In this case, for example, "toilet space" can be read as "water-related space," "shower space," or "hot water supply space." Also, "toilet booth" can be read as "private room space," "shower booth," or "hot water supply booth." Furthermore, "toilet equipment" can be read as "water-related equipment," "shower equipment," or "hot water supply equipment."

[0111] Furthermore, the embodiments and modifications described above can be combined as appropriate, provided that the processing content is not contradictory. Further effects and modifications can be easily derived by those skilled in the art. For this reason, broader aspects of the present invention are not limited to the specific details and representative embodiments expressed and described above. Accordingly, various modifications are possible without departing from the spirit or scope of the overall concept of the invention as defined by the appended claims and equivalents.
