Description

[Technical Field]

[0001] The present invention relates to a toilet system and a toilet device. [Background technology]

[0002] Conventionally, toilet devices capable of measuring a user's excrement and determining the user's health condition have been known. For example, Patent Document 1 proposes a toilet device that takes an image of excrement that has fallen into the toilet bowl after personal authentication is completed. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2023-110839 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the technology described in Patent Document 1, an image is captured after personal authentication is completed, so excrement information cannot be acquired if there is no time to perform personal authentication before excretion.

[0005] In view of the above problems, the present invention aims to provide a toilet system and a toilet device that can acquire excrement information of a user even if the user does not have time to perform personal authentication before excretion. [Means for solving the problem]

[0006] To solve the above problems, according to a first aspect of the present invention, the following toilet system is provided: This toilet system includes a server device and a toilet device connected to the server device, a measurement unit provided in the toilet device that measures the excrement of a user using the toilet device, an authentication unit that performs personal authentication of the user, and a control unit provided in the toilet device that controls the measurement unit to start measuring the excrement of the user before the personal authentication is completed.

[0007] According to this configuration, the measurement of excrement begins before the completion of personal authentication of the user, so even if the user does not have time to undergo personal authentication before excretion, the excrement can be measured and excrement information of the user can be obtained.

[0008] In addition, the toilet system according to the second aspect of the present invention further includes an authentication reception unit provided in the toilet device that receives personal authentication information of the user, and the control unit begins measuring the user's excrement before receiving the personal authentication information.

[0009] With this configuration, excrement measurement begins before the user's personal authentication information is received, compared to when excrement measurement begins after personal authentication information is received. Therefore, even if the user does not have time to undergo personal authentication before excretion, the excrement can be measured and excrement information for that user can be obtained.

[0010] In addition, the toilet system according to the third aspect of the present invention further includes an authentication reception unit provided in the toilet device that receives personal authentication information of the user, and the control unit starts measuring the user's excrement after receiving the personal authentication information and before the personal authentication is completed.

[0011] According to this configuration, the measurement of excrement begins before the completion of personal authentication of the user, so even if the user does not have time to undergo personal authentication, the excrement can be measured and excrement information of the user can be obtained.

[0012] In addition, in the toilet system according to the fourth aspect of the present invention, the measured excrement information is transmitted to the server device, and the server device receives the user's personal authentication information and the excrement information, and further includes a memory unit provided in the server device that stores the personal authentication information and the excrement information in association with each other.

[0013] According to this configuration, the excrement information is stored independently of the execution of personal authentication, so that even if personal authentication is not completed, the excrement information can be prevented from being lost.

[0014] In addition, in the toilet system according to a fifth aspect of the present invention, the server device is configured to be able to communicate with a terminal of the user, and the personal authentication information is transmitted from the terminal to the server device.

[0015] According to this configuration, personal authentication is possible from the user's terminal, which improves user convenience compared to when personal authentication is not possible from the user's terminal.

[0016] In addition, in a toilet system according to a sixth aspect of the present invention, the toilet device transmits identification information that identifies the excrement information to the terminal, and further transmits the identification information together with the excrement information to the server device, the terminal transmits the identification information together with the personal authentication information to the server device, the authentication unit determines whether the identification information received from the toilet device matches the identification information received from the terminal, and when the authentication unit determines that the identification information matches, the memory unit associates and stores the personal authentication information and the excrement information received together with the identification information.

[0017] According to this configuration, compared to a case where there is no identification information associated with the excrement information, the excrement information and the personal authentication information can be more reliably associated with each other based on the identification information.

[0018] In addition, in a toilet system according to a seventh aspect of the present invention, the toilet device transmits identification information for identifying the excrement information to the server device together with the excrement information, the server device transmits a plurality of the identification information to the terminal, the terminal or the user selects one of the plurality of identification information, the terminal transmits the selected one of the identification information to the server device together with the personal authentication information, the authentication unit determines whether the identification information received from the toilet device matches the identification information received from the terminal, and when the authentication unit determines that the identification information matches, the memory unit associates and stores the personal authentication information received together with the identification information and the excrement information.

[0019] According to this configuration, the identification information is transmitted from the server device to the terminal, so that even if the terminal does not receive the identification information from the toilet device, the excrement information can be associated with the personal authentication information.

[0020] In addition, in the toilet system according to the eighth aspect of the present invention, the identification information transmitted from the server device to the terminal includes additional identification information such as a measurement identifier of the excrement information, installation location information of the toilet device, owner information of the toilet device, measurement date and time of the excrement information, the name of the toilet device, or an identifier of the toilet device.

[0021] According to this configuration, by displaying information that provides clues for the terminal or user to select whether the information is related to the user's excretion, it becomes easier to select the terminal or user's identification information compared to when information that provides clues for the terminal or user to select whether the information is related to the user's excretion is not displayed.

[0022] In addition, in a toilet system according to a ninth aspect of the present invention, the server device receives the identification information and the personal authentication information multiple times from multiple terminals, and the authentication unit selects one of the identification information and the personal authentication information from the multiple received identification information and the personal authentication information based on predetermined conditions.

[0023] According to this configuration, even if erroneous personal authentication information is associated with excrement information, personal authentication can be performed again to newly associate the excrement information with the personal authentication information.

[0024] In addition, a toilet system according to a tenth aspect of the present invention further includes a remote control having a plurality of user identification keys, wherein the toilet device transmits identification information that identifies the excrement information to the remote control and further transmits the identification information together with the excrement information to the server device, the plurality of user identification keys are assigned the personal authentication information of different users, the remote control transmits the identification information together with the personal authentication information to the server device, the authentication unit determines whether the identification information received from the toilet device matches the identification information received from the remote control, and when the authentication unit determines that the identification information matches, the memory unit associates and stores the personal authentication information and the excrement information received together with the identification information.

[0025] According to this configuration, personal authentication can be performed even with a remote controller.

[0026] Furthermore, to solve the above-mentioned problems, according to an eleventh aspect of the present invention, there is provided the following toilet device: This toilet device is connected to a server device, and includes a measurement unit that measures the excrement of a user who uses the toilet device, an authentication reception unit that receives personal authentication information of the user, and a control unit that controls the measurement unit to start measuring the excrement of the user before receiving the personal authentication information.

[0027] According to this configuration, the measurement of excrement begins before the user's personal authentication information is received, so that the measurement of excrement can be carried out even if the user does not have time to undergo personal authentication. [Effects of the Invention]

[0028] According to the toilet system and toilet device of the present invention, even if the user does not have time to undergo personal authentication, the excrement information of the user can be obtained. [Brief explanation of the drawings]

[0030] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. To facilitate understanding of the description, the same components in the drawings will be denoted by the same reference numerals as much as possible, and duplicated descriptions will be omitted.

[0031] ---First embodiment--- First, a toilet system 1A according to a first embodiment will be described.

[0032] <Overall structure> FIG. 1 is a diagram schematically illustrating an example of the overall configuration of a toilet system 1A according to a first embodiment of the present invention.

[0033] As shown in Fig. 1, the toilet system 1A includes a toilet device 2 and a server device 5. The toilet device 2 is provided, for example, in a toilet room R. The toilet room R may be, for example, a public toilet available to many people, such as in a station, airport, commercial facility, or office building, or may be a home toilet. The toilet room R is provided with a toilet door D.

[0034] The toilet device 2 is a device for treating excrement of a user. The toilet device 2 includes a toilet bowl 11 and an operating device 23.

[0035] The toilet bowl 11 is, for example, a ceramic toilet bowl. A toilet seat is disposed on the upper surface of the toilet bowl 11.

[0036] The operating device 23 is used to operate the toilet device 2, and is installed, for example, on the wall of the toilet room R. The operating device 23 is capable of wired or wireless communication with the toilet device 2 and the like, and is capable of sending and receiving information. The operating device 23 accepts various operations from the user via a touch panel or buttons, and executes processing. A liquid crystal panel, an organic EL display, or the like may be provided on the outer surface of the operating device 23 to display various information.

[0037] The toilet device 2 is connected to a server device 5 via a network such as the Internet or an intranet, and communicates with the server device 5.

[0038] The server device 5 is configured to be able to communicate with the user's terminal 7. For example, the server device 5 is connected to the terminal 7 via the Internet using a communication standard such as LTE (registered trademark) or Wi-Fi (registered trademark).

[0039] The terminal 7 is, for example, a smartphone. The terminal 7 may be, for example, a personal property of the user, or may be attached to the toilet device 2. The terminal 7 is configured to be able to communicate with the toilet device 2. For example, the terminal 7 and the toilet device 2 are connected via Bluetooth (registered trademark).

[0040] <Function blocks, etc.> FIG. 2 is a block diagram showing the functional blocks of the toilet system 1A of FIG.

[0041] First, we will explain the toilet device 2. As shown in Figure 2, a control device 3 is disposed within the toilet device 2. The control device 3 is configured partially or entirely with analog circuits, or with a digital processor or memory. The control device 3 has, as functional blocks, an authentication reception unit 31, a control unit 33, a storage unit 35, a communication unit 37, and an authentication unit 39.

[0042] The authentication receiving unit 31 receives personal authentication information for performing personal authentication of a user who uses the toilet device 2. The authentication receiving unit 31 may be provided in the operation device 23. The control unit 33 performs various controls based on signals received by the control device 3 from outside. The control unit 33 controls the measurement unit 21 to start measuring the user's excrement before the completion of personal authentication performed based on the personal authentication information. The memory unit 35 stores various setting information and parameters, personal authentication information for performing personal authentication of the user, excrement information related to the excrement, etc. The authentication unit 39 performs personal authentication of a user who uses the toilet device 2. The personal authentication information includes attribute information such as a user number, symbol, facial photograph, fingerprint information, name, age, and address, for example. The communication unit 37 transmits and receives signals to and from outside the toilet device 2, for example, the terminal 7 and the server device 5.

[0043] The control device 3 is connected to the measurement unit 21 that measures the user's excrement, the operating device 23 described above, the human body detection sensor 41 as a human body detection unit, and the seating detection sensor 43 as a seating detection unit so as to be able to transmit control signals. The measurement unit 21 is, for example, an image sensor that receives an image signal, a laser emission device that irradiates laser light, or a detection sensor that detects reflected laser light, and measures the user's excrement and acquires excrement information. The human body detection sensor 41 detects a user (human body) entering the toilet room R. The human body detection sensor 41 is, for example, an infrared sensor, an ultrasonic sensor, or a microwave sensor. The seating detection sensor 43 detects when a user sits on the toilet seat. The control device 3 can receive image signals, etc. from the measurement unit 21 and receive detection signals from the human body detection sensor 41 and the seating detection sensor 43.

[0044] Next, the server device 5 will be described. The server device 5 has, as functional blocks, a communication unit 51, a control unit 53, and a storage unit 55. The communication unit 51 transmits and receives signals to and from the outside of the server device 5, such as the terminal 7 or the toilet device 2. The communication unit 51 receives, for example, personal authentication information received by the authentication reception unit 31 and excrement information measured by the measurement unit 21. The control unit 53 performs various controls based on signals received by the server device 5 from the outside. The storage unit 55 stores various setting information and parameters, personal authentication information, excrement information, etc. The storage unit 55 also stores the personal authentication information and excrement information in association with each other.

[0045] Finally, the terminal 7 will be described. The terminal 7 has, as functional blocks, a communication unit 71, an operation unit 73, a display unit 75, and a control unit 77. The communication unit 71 transmits and receives signals to and from the outside of the terminal 7, such as the server device 5 or the toilet device 2. The operation unit 73 is an input device such as a sensor or a switch that allows the user to input operation instructions to the terminal 7. The display unit 75 is a display device that displays an operation screen and various information for the user to operate the terminal 7. The operation unit 73 and the display unit 75 are, for example, a touch panel display of a smartphone. The control unit 77 performs various controls based on the information received by the communication unit 71 and the operation instructions input to the operation unit 73.

[0046] It should be noted that the software modules incorporated into the control device 3, the server device 5, and the terminal 7 do not necessarily need to be divided into functional blocks as shown in Fig. 2. In other words, actual analog circuits and modules may be configured to perform the functions of the multiple functional blocks shown in Fig. 2, or may be further subdivided. The configurations of the control device 3, the server device 5, and the terminal 7 can be modified as appropriate by those skilled in the art as long as they are configured to be able to execute the processes described below.

[0047] <Example of operation> Personal authentication is performed, for example, as follows: First, the user searches for the toilet device 2 on their own terminal 7, and, if necessary, enters the connection password of the toilet device 2, etc., to pair the terminal 7 with the toilet device 2. Next, if necessary, one or more items of personal authentication information are entered on the operation unit 73 of the terminal 7, etc., and the personal authentication information is transmitted from the communication unit 71 to the toilet device 2. The authentication reception unit 31 of the toilet device 2 receives the personal authentication information. The authentication unit 39 performs personal authentication of the user of the toilet device 2 based on the received personal authentication information and the personal authentication information stored in the memory unit 35, and completes the personal authentication.

[0048] The excrement measurement is performed, for example, as follows. The control unit 33 of the control device 3 controls the measurement unit 21 to measure the user's excrement. For example, the measurement unit 21 is an image sensor that captures an image of the excrement. The image sensor transmits an image signal corresponding to the captured image of the excrement to the control device 3. The control device 3 receives the image signal, stores the image based on the image signal in the memory unit 35, and generates excrement information, such as the presence or absence of the user's feces or urine, and the color, shape, and amount of the feces or urine, from the image based on the image signal, based on a predetermined program. The communication unit 37 of the control device 3 transmits this excrement information to the server device 5. By accessing this server device 5 and obtaining the excrement information, medical professionals and others can understand the user's health condition and provide advice based on that information. Of course, the user or authorized family members can also access this server device 5 and obtain the excrement information to understand the user's health condition.

[0049] <Acquisition of excrement information> The toilet system 1A is designed to acquire excrement information even when the user does not have time to undergo personal authentication before excretion. This point will be described below.

[0050] The control unit 33 of the control device 3 controls the measurement unit 21 to measure the user's excrement. Here, the excrement measurement is performed independently of the progress of personal authentication in the authentication unit 39 of the control device 3 described above. That is, the excrement measurement may be started before the personal authentication in the authentication unit 39 of the control device 3 is completed, before the personal authentication information is received in the communication unit 37 of the control device 3, or before the personal authentication information is received in the authentication reception unit 31 of the control device 3. Furthermore, the excrement measurement may be started based on a detection signal from the human body detection sensor 41 or the seating detection sensor 43, may be started upon detection of the opening or closing of the toilet door D, or may be started based on the user's operation of the operating device 23. In this way, the excrement measurement is performed independently of the progress of personal authentication, making it possible to obtain excrement information even if the user does not have time to undergo personal authentication before defecation.

[0051] FIG. 3 is a model diagram showing the processing flow of the toilet system 1A of FIG.

[0052] <Processing flow> An example of a series of processing steps for acquiring a user's excrement information even when the user does not have time to undergo personal authentication before excretion will be described below with reference to Figure 3. Step SP1 for measuring the excrement and storing the excrement information and step SP5 for performing personal authentication proceed independently.

[0053] (Step SP1) The control unit 33 of the toilet device 2 controls the measurement unit 21 to measure excrement based on detection signals from the human body detection sensor 41 or the seating detection sensor 43. That is, when the toilet device 2 detects a human body or a user sitting on the toilet seat, the measurement unit 21 starts measuring excrement. The control unit 33 generates excrement information from signals measured and acquired by the measurement unit 21, for example, image signals captured by an image sensor.

[0054] (Step SP5) The toilet device 2 and the terminal 7 are paired, and personal authentication information is input via the operation unit 73 or the like of the terminal 7. Then, the communication unit 71 transmits the input personal authentication information to the toilet device 2. The communication unit 37 of the toilet device 2 receives the personal authentication information. Then, the authentication reception unit 31 of the toilet device 2 accepts the received personal authentication information. Then, the authentication unit 39 performs personal authentication of the user based on the received personal authentication information and the personal authentication information stored in the memory unit 35, and completes the personal authentication. Then, the process proceeds to step SP6.

[0055] (Step SP6) When the control unit 33 of the toilet device 2 determines that the personal authentication information and the excrement information have been collected, the communication unit 37 associates the personal authentication information with the excrement information and transmits them to the server device 5. Then, the process proceeds to step SP7.

[0056] (Step SP7) The communication unit 51 of the server device 5 receives the personal authentication information and the excrement information. The storage unit 55 stores the personal authentication information and the excrement information in association with each other. Then, the series of processes shown in FIG. 3 ends.

[0057] In the above series of processes, a flow has been described in which personal authentication information is input into the terminal 7 and personal authentication is performed by the toilet device 2, but personal authentication information may also be input without going through the terminal 7. For example, personal authentication information may be input into the operation device 23 of the toilet device 2 and accepted by the authentication accepting unit 31. Also, personal authentication may not be performed by the authentication unit 39 of the control device 3 of the toilet device 2, but the personal authentication information may be transmitted from the toilet device 2 to the server device 5, and an authentication unit that performs personal authentication may be provided in the server device 5. In this case, the toilet device 2 transmits to the server device 5 personal authentication information for which personal authentication has not been completed, in association with excrement information. Alternatively, a notification that personal authentication has been completed by the authentication unit of the server device 5 may be transmitted to the toilet device 2, and the personal authentication information and excrement information may be transmitted to the server device 5 in association with each other.

[0058] <Action and effect> As described above, the toilet system 1A of this embodiment is a toilet system 1A comprising a server device 5 and a toilet device 2 connected to the server device 5, and further comprising a measurement unit 21 provided in the toilet device 2 to measure the excrement of a user using the toilet device 2, an authentication unit 39 to perform personal authentication of the user, and a control unit 33 provided in the toilet device 2 to control the measurement unit 21 to start measuring the excrement of the user before the personal authentication is completed.

[0059] According to this configuration, the measurement of excrement begins before the completion of personal authentication of the user, so even if the user does not have time to undergo personal authentication before excretion, the excrement can be measured and excrement information can be obtained.

[0060] The toilet system 1A further includes an authentication reception unit 31 that is provided in the toilet device 2 and receives personal authentication information of the user, and the control unit 33 starts measuring the user's excrement before receiving the personal authentication information.

[0061] With this configuration, excrement measurement begins before the user's personal authentication information is received, compared to when excrement measurement begins after personal authentication information is received. Therefore, even if the user does not have time to undergo personal authentication before excretion, excrement measurement can be performed and excrement information can be obtained.

[0062] In addition, the toilet system 1A further includes an authentication reception unit 31 provided in the toilet device 2 that receives the user's personal authentication information, and the control unit 33 starts measuring the user's excrement after receiving the personal authentication information and before the personal authentication is completed.

[0063] According to this configuration, the measurement of excrement begins before the completion of personal authentication of the user, so even if the user does not have time to undergo personal authentication before excretion, the excrement can be measured and excrement information can be obtained.

[0064] In addition, in the toilet system 1A, the acquisition of excrement information and the acquisition of personal authentication information are performed independently in the toilet device 2, and the server device 5 receives the user's personal authentication information and excrement information, and further includes a memory unit 55 provided in the server device 5 that stores the personal authentication information and excrement information in association with each other.

[0065] According to this configuration, the excrement information is stored independently of the execution of personal authentication, so that even if personal authentication is not completed before excretion, the excrement information can be prevented from being lost.

[0066] Furthermore, the toilet device 2 according to this embodiment is a toilet device 2 connected to a server device 5, and includes a measurement unit 21 that measures the excrement of a user who uses the toilet device 2, an authentication reception unit 31 that receives personal authentication information of the user, and a control unit 33 that controls the measurement unit 21 to start measuring the excrement of the user before receiving the personal authentication information.

[0067] According to this configuration, the measurement of excrement begins before the user's personal authentication information is received, so that the measurement of excrement can be carried out even if the user does not have time to undergo personal authentication.

[0068] In this embodiment, the mode in which personal authentication is completed by the toilet device 2 is suitable for toilet rooms in home toilets or toilet rooms in small offices. Also, the mode in which personal authentication is completed by the server device 5 is particularly suitable for toilet rooms in public toilets that can be used by an unspecified number of people, such as those in stations, airports, commercial facilities, or office buildings, but can also be applied to toilet rooms in home toilets.

[0069] In the toilet system 1A of this embodiment, personal authentication information and excrement information are associated with each other and stored in the server device 5. For example, if the server device 5 is connected to a single toilet device 2, it is not possible to store excrement information based on a user's excretion in another toilet device 2. Therefore, the server device 5 is connected to each of a toilet device 2 installed in a toilet room of a home toilet and a toilet device 2 installed in a toilet room of a public toilet such as a station, airport, commercial facility, or office building via a predetermined network or via a terminal carried by the user, and the personal authentication information and excrement information acquired from each toilet device 2 are stored in the server device 5, thereby preventing gaps in the user's excrement information stored in the server device 5. As a result, for example, even if a user who uses a toilet device 2 at home also uses a toilet device 2 installed in a public space other than the home, the excrement information can be collectively managed by the server device 5, and the user's health condition can be more appropriately determined using the excrement information acquired through toilet use at home and away from home.

[0070] ---Second embodiment--- Next, a toilet system 1B according to a second embodiment will be described with reference to Figs. 4 and 5. Fig. 4 is a block diagram showing functional blocks of the toilet system 1B according to the second embodiment. Fig. 5 is a model diagram showing the processing flow of the toilet system 1B according to the second embodiment. In the toilet system 1B according to the second embodiment, the processing flow in the toilet system 1B differs from that in the first embodiment. In the toilet system 1B according to the second embodiment, the same components as those in the first embodiment are assigned the same reference numerals, and descriptions thereof will be omitted as appropriate.

[0071] <Function blocks, etc.> In the toilet system 1B, the server device 5 is provided with an authentication unit 57 that performs personal authentication based on personal authentication information.

[0072] <Processing flow> Hereinafter, an example of a series of processing steps for acquiring excrement information of a user even when the user does not have time to undergo personal authentication will be described with reference to FIG.

[0073] Here, the control unit 33 generates identification information for identifying the excrement information. The identification information is information that uniquely identifies the excrement information, and is, for example, a measurement identifier or measurement number such as a UUID (Universally Unique IDentifier). The identification information may include identification information such as installation location information of the toilet device 2, owner information of the toilet device 2, measurement date and time of the excrement information, name of the toilet device 2, or identifier of the toilet device 2, alone or in combination with multiple pieces of identification information. Note that the identification information transmitted from the toilet device 2 is referred to as first identification information, and the identification information transmitted from the terminal 7 is referred to as second identification information. The second identification information may be the same as the first identification information, or may be converted to a compression rate different from that of the first identification information, or may be encrypted, for example.

[0074] (Step SP20) The control unit 33 of the toilet device 2 controls the measurement unit 21 to measure excrement based on the detection signal of the human body detection sensor 41 or the seating detection sensor 43. Then, the control unit 33 generates excrement information from the information measured by the measurement unit 21. The control unit 33 also generates first identification information for identifying the excrement information. Then, the communication unit 37 of the toilet device 2 transmits the first identification information together with the measured excrement information to the server device 5. Then, the process proceeds to step SP21.

[0075] (Step SP21) Furthermore, the communication unit 37 of the toilet device 2 also transmits the first identification information to the terminal 7. Here, the terminal 7 to which the first identification information is transmitted is not limited to the terminal 7 owned by the user, but may include one or more terminals owned by third parties near the user. Then, the process proceeds to step SP22.

[0076] (Step SP22) The terminal 7 receives the first identification information from the toilet device 2. Then, personal authentication information is input via the operation unit 73 of the terminal 7. The control unit 77 of the terminal 7 may process the first identification information, such as by encrypting or compressing it, to generate second identification information for transmission to the server device 5. Then, the communication unit 71 of the terminal 7 transmits the second identification information together with the personal authentication information to the server device 5. Here, the second identification information may be the same as the first identification information. Furthermore, among the multiple terminals 7 that have received the first identification information, the communication units 71 of two or more terminals 7 may transmit different personal authentication information and second identification information based on the same first identification information to the server device 5. For example, if the first identification information is transmitted to a terminal of a user other than the terminal 7 of the user who performed the excretion related to the excretion information, different personal authentication information and second identification information based on the same first identification information may be transmitted to the server device 5 from the terminal of the other user and the terminal 7 of the user who performed the excretion. Then, the process proceeds to step SP23.

[0077] (Step SP23) The communication unit 51 of the server device 5 receives the second identification information and the personal authentication information from the terminal 7. Then, the communication unit 51 of the server device 5 transmits a transmission confirmation signal to the terminal 7 notifying that the second identification information and the personal authentication information have been transmitted. Then, the process proceeds to step SP24.

[0078] (Step SP24) The terminal 7 receives the transmission confirmation signal. Then, for example, a transmission confirmation screen is displayed on the display unit 75, and the user confirms that the personal authentication information sent by the user is the personal authentication information sent by the user. The communication unit 71 of the terminal 7 transmits a content confirmation signal to the server device 5, notifying that the user has confirmed the content of the transmission. Then, the process proceeds to step SP25.

[0079] (Step SP25) The authentication unit 57 of the server device 5 determines whether the first identification information received from the toilet device 2 in step SP20 matches the second identification information received from the terminal 7 in step SP22. If it is determined that the first identification information matches the second identification information, the authentication unit 57 performs personal authentication based on the personal authentication information transmitted to the server device 5 together with the second identification information. Then, the process proceeds to step SP26.

[0080] (Step SP26) When the storage unit 55 of the server device 5 determines that the first identification information received from the toilet device 2 and the second identification information received from the terminal 7 match, the storage unit 55 associates and stores the personal authentication information and excrement information received together with the identification information. Furthermore, when the authentication unit 57 receives identification information and personal authentication information multiple times from multiple terminals 7, the authentication unit 57 selects one of the identification information and personal authentication information from the identification information and personal authentication information received multiple times based on a predetermined condition. Specifically, when the storage unit 55 associates and stores one of the personal authentication information and excrement information, the authentication unit 57 determines whether the excrement information and other personal authentication information have already been stored in association with each other. When the storage unit 55 determines that the excrement information and other personal authentication information have already been stored in association with each other, the storage unit 55 overwrites and associates the excrement information with the one of the personal authentication information. That is, when the storage unit 55 determines that the excrement information has already been stored in association with other personal authentication information in the authentication unit 57, it disassociates the excrement information from the other personal authentication information and stores the excrement information in association with one personal authentication information. For example, if personal authentication information of a user other than the user who performed the excretion related to the excretion information is mistakenly associated with the excretion information, the user who performed the excretion related to the excretion information can overwrite and associate the excretion information with the personal authentication information of the user who performed the excretion related to the excretion information. Then, the series of processes shown in FIG. 5 ends.

[0081] <Action and effect> As described above, in the toilet system 1B of the second embodiment, the measured excrement information is transmitted to the server device 5, and the server device 5 receives the user's personal authentication information and excrement information, and further includes a memory unit 55 provided in the server device 5 that stores the personal authentication information and excrement information and the association between the personal authentication information and the excrement information.

[0082] According to this configuration, the excrement information is stored independently of the execution of personal authentication, so that even if personal authentication is not completed before excretion, the excrement information can be prevented from being lost.

[0083] In the toilet system 1B, the server device 5 is configured to be able to communicate with the terminal 7 of the user, and the personal authentication information is transmitted from the terminal 7 to the server device 5.

[0084] According to this configuration, personal authentication is possible from the user terminal 7, and compared to a case where personal authentication is not possible from the user terminal 7, convenience for the user is improved.

[0085] In addition, in the toilet system 1B, the toilet device 2 transmits identification information that identifies the excrement information to the terminal 7, and further transmits the identification information together with the excrement information to the server device 5, the terminal 7 transmits the identification information together with the personal authentication information to the server device 5, the authentication unit 57 determines whether the identification information received from the toilet device 2 matches the identification information received from the terminal 7, and when the authentication unit 57 determines that the identification information matches, the memory unit 55 associates and stores the personal authentication information received together with the identification information with the excrement information.

[0086] According to this configuration, compared to a case where there is no identification information associated with the excrement information, the excrement information and the personal authentication information can be more reliably associated with each other based on the identification information.

[0087] In addition, in the toilet system 1B, the server device 5 receives identification information and personal authentication information multiple times from multiple terminals 7, and the authentication unit 57 selects one piece of identification information and personal authentication information from the identification information and personal authentication information received multiple times based on predetermined conditions.

[0088] According to this configuration, even if erroneous personal authentication information is associated with excrement information, personal authentication can be performed again to newly associate the excrement information with the personal authentication information.

[0089] ---Third embodiment--- Next, a toilet system 1C according to a third embodiment will be described with reference to Figs. 4 and 6. Fig. 6 is a model diagram showing the processing flow of the toilet system 1C according to the third embodiment. In the toilet system 1C according to the third embodiment, the processing flow in the toilet system 1C differs from that in the first and second embodiments. In the toilet system 1C according to the third embodiment, the same components as those in the first or second embodiment are denoted by the same reference numerals, and descriptions thereof will be omitted as appropriate.

[0090] <Processing flow> An example of a series of processing steps for acquiring a user's excrement information even when the user does not have time to undergo personal authentication will be described below with reference to Figure 6. The identification information transmitted from the server device 5 is referred to as third identification information. The third identification information may be the same as the first identification information or the second identification information, and may be converted to a compression rate different from that of the first identification information or the second identification information, or may be encrypted.

[0091] (Step SP30) The control unit 33 of the toilet device 2 controls the measurement unit 21 based on the detection signal of the human body detection sensor 41 to measure the excrement. Then, the control unit 33 generates excrement information from the information measured by the measurement unit 21. The control unit 33 also generates first identification information for identifying the excrement information. Then, the communication unit 37 of the toilet device 2 transmits the measured excrement information together with the first identification information to the server device 5. Here, a single toilet device 2 transmits a plurality of different excrement information and a plurality of different first identification information each time a user changes. Note that a plurality of toilet devices 2 may transmit a plurality of different excrement information and a plurality of different first identification information. Then, the process proceeds to step SP31.

[0092] (Step SP31) The communication unit 51 of the server device 5 receives the excrement information and the first identification information multiple times each time the user changes. The control unit 53 of the server device 5 may generate third identification information by encrypting, compressing, or otherwise processing the first identification information in order to transmit it to the terminal 7. The communication unit 51 transmits to the terminal 7 third identification information based on multiple first identification information that satisfy a predetermined condition among the multiple received first identification information. Here, the predetermined condition may be a condition related to the toilet device 2 from which the excrement information was obtained, such as the individual number of the toilet device 2, its installation location, the nearest train station, etc. The third identification information may be the same information as the first identification information. The third identification information transmitted to the terminal 7 may include additional identification information such as a measurement identifier of the excrement information, installation location information of the toilet device 2, owner information of the toilet device 2, measurement date and time of the excrement information, the name of the toilet device 2, and an identifier of the toilet device 2. Then, the process proceeds to step SP32.

[0093] (Step SP32) The communication unit 51 of the terminal 7 receives the third identification information. Then, personal authentication information is input via the operation unit 73 of the terminal 7. The user selects one piece of third identification information from the multiple pieces of third identification information. The control unit 77 of the terminal 7 may also generate second identification information by encrypting or compressing the third identification information to transmit it to the server device 5. The communication unit 71 of the terminal 7 then transmits the second identification information based on the selected third identification information together with the personal authentication information to the server device 5. Here, the second identification information may be the same as the third identification information or may be partially the same as the third identification information. Here, the terminal 7 may select one piece of third identification information from the multiple pieces of third identification information based on, for example, past location information of the terminal 7. Then, the process proceeds to step SP33.

[0094] (Step SP33) The communication unit 51 of the server device 5 receives the second identification information and the personal authentication information from the terminal 7. Then, the authentication unit 57 of the server device 5 determines whether the first identification information received from the toilet device 2 in step SP30 matches the second identification information received from the terminal 7 in step SP32. If it is determined that the first identification information and the second identification information match, personal authentication is performed based on the personal identification information transmitted together with the second identification information. Then, the process proceeds to step SP34.

[0095] (Step SP34) When the authentication unit 57 determines that the first identification information and the second identification information match, the storage unit 55 of the server device 5 stores the association between the personal authentication information and the excrement information received together with the identification information. Then, the series of processes shown in FIG. 6 ends.

[0096] <Action and effect> As described above, in the toilet system 1C according to the third embodiment, the toilet device 2 transmits identification information for identifying the excrement information to the server device 5 along with the excrement information, at least one of the identification information includes multiple identification information, the server device 5 transmits the multiple identification information to the terminal 7, the terminal 7 or the user selects one of the multiple identification information, the terminal 7 transmits the selected one of the identification information together with personal authentication information to the server device 5, the authentication unit 57 determines whether the identification information received from the toilet device 2 matches the identification information received from the terminal 7, and when the authentication unit 57 determines that the identification information matches, the memory unit 55 stores the association between the personal authentication information and the excrement information received together with the identification information.

[0097] According to this configuration, the identification information is transmitted from the server device 5 to the terminal 7, so that even if the terminal 7 does not receive the identification information from the toilet device 2, the excrement information can be associated with the personal authentication information.

[0098] In addition, in the toilet system 1C, the identification information transmitted from the server device 5 to the terminal 7 includes additional identification information such as a measurement identifier for the excrement information, installation location information for the toilet device 2, owner information for the toilet device 2, measurement date and time of the excrement information, the name of the toilet device 2, or an identifier for the toilet device 2.

[0099] According to this configuration, by displaying information that can help the terminal 7 or the user to select whether the information is related to the user's excretion, it becomes easier to select the terminal 7 or the user's identification information compared to when information that can help the terminal 7 or the user to select whether the information is related to the user's excretion is not displayed.

[0100] ---Fourth embodiment--- Next, a toilet system 1D according to a fourth embodiment will be described with reference to Figs. 4 and 7. Fig. 7 is a model diagram showing the processing flow of the toilet system 1D according to the fourth embodiment. In the toilet system 1D according to the fourth embodiment, the processing flow in the toilet system 1D differs from that in the first, second, and third embodiments. In the toilet system 1D according to the third embodiment, the same components as those in the first, second, or third embodiment are designated by the same reference numerals, and descriptions thereof will be omitted as appropriate.

[0101] 7, the toilet system 1D further includes a remote control 9. The remote control 9 may be provided in the operation device 23 or may be provided separately from the operation device 23.

[0102] The remote control 9 has a plurality of user-specific keys 91 and an optional key 93. Personal authentication information of different users is assigned to each of the plurality of user-specific keys 91. When a user selects one of the user-specific keys 91, the personal authentication information assigned to that user-specific key 91 is transmitted to the server device 5. For example, when a user presses one of the user-specific keys 91, the personal authentication information assigned to that user-specific key 91 is transmitted to the server device 5. The key 93 is a key for executing functions of the toilet device 2, such as opening and closing the toilet seat, flushing the toilet bowl 11, and starting or stopping the private parts washing function or private parts drying function.

[0103] <Processing flow> An example of a series of processing steps for acquiring excrement information of a user even when the user does not have time to undergo personal authentication will be described below with reference to Fig. 7. Note that the identification information transmitted from the remote control 9 or the terminal 7 is referred to as second identification information.

[0104] (Step SP40) The control unit 33 of the toilet device 2 controls the measurement unit 21 based on the detection signal from the human body detection sensor 41 or the seating detection sensor 43 to measure the excrement. Then, the control unit 33 generates excrement information from the information measured by the measurement unit 21. The control unit 33 also generates first identification information for identifying the excrement information. Then, the communication unit 37 of the toilet device 2 transmits the measured excrement information together with the first identification information for identifying the excrement information to the server device 5. Then, the process proceeds to step SP41.

[0105] (Step SP41) The communication unit 37 of the toilet apparatus 2 transmits the first identification information to the remote control 9 and / or the terminal 7. Then, the process proceeds to step SP42.

[0106] (Step SP42) The remote control 9 or the terminal 7 receives the first identification information from the toilet device 2. When the user presses one of the user identification keys 91, the personal authentication information assigned to that user identification key 91 is transmitted to the server device 5. The remote control 9 may process the first identification information, such as by encrypting or compressing it, to generate second identification information for transmission to the server device 5. The remote control 9 transmits second identification information based on the first identification information together with the personal authentication information of the user corresponding to each user identification key 91 to the server device 5. Here, the communication unit 71 of the terminal 7 may transmit the personal authentication information and the second identification information to the server device 5. Then, the processing proceeds to step SP43.

[0107] (Step SP43) The communication unit 51 of the server device 5 receives the second identification information and the personal authentication information from the remote control 9 or the terminal 7. Then, the communication unit 51 of the server device 5 transmits a transmission confirmation signal to the remote control 9 or the terminal 7 to notify that the second identification information and the personal authentication information have been transmitted. Then, the process proceeds to step SP44.

[0108] (Step SP44) The remote control 9 or the communication unit 71 of the terminal 7 receives the transmission confirmation signal. Then, for example, the user identification key 91 lights up, or a voice guide is given, etc., to confirm that the personal authentication information sent by the user is the information sent by the user. The remote control 9 or the communication unit 71 of the terminal 7 transmits a content confirmation signal to the server device 5 notifying that the user has confirmed the transmitted content. Then, the process proceeds to step SP45.

[0109] (Step SP45) The authentication unit 57 of the server device 5 determines whether the first identification information received from the toilet device 2 in step SP40 matches the second identification information received from the remote control 9 or the terminal 7 in step SP42. If it is determined that the first identification information matches the second identification information, personal authentication is performed based on the personal authentication information transmitted from the remote control 9 or the terminal 7 to the server device 5 together with the second identification information. Then, the process proceeds to step SP46.

[0110] (Step SP46) When the authentication unit 57 determines that the first identification information and the second identification information match, the storage unit 55 of the server device 5 stores the association between the personal authentication information and the excrement information. Then, the series of processes shown in FIG. 7 ends.

[0111] <Action and effect> As described above, the toilet system 1D of the fourth embodiment further includes a remote control 9 having a plurality of user identification keys 91, the toilet device 2 transmits identification information that identifies excrement information to the remote control 9, and further transmits the identification information together with the excrement information to the server device 5, the plurality of user identification keys 91 are assigned personal authentication information of different users, the remote control 9 transmits the identification information together with the personal authentication information to the server device 5, the authentication unit 57 determines whether the identification information received from the toilet device 2 matches the identification information received from the remote control 9, and when the authentication unit 57 determines that the identification information matches, the memory unit 55 stores the association between the personal authentication information and excrement information received together with the identification information.

[0112] The toilet device 2 according to the fourth embodiment is suitable for a toilet room of a home toilet because the number of user-specific keys 91 on the remote controller 9 is limited.

[0113] According to this configuration, even the remote controller 9 can be used for personal authentication.

[0114] ---Variations--- The present invention is not limited to the above-described embodiments. In other words, variations on the above-described specific examples, which are appropriately modified by a person skilled in the art, are also included within the scope of the present invention as long as they include the features of the present invention. Furthermore, the elements of the above-described embodiments and the following modifications can be combined to the extent technically possible, and such combinations are also included within the scope of the present invention as long as they include the features of the present invention.

[0115] For example, in the first embodiment, the toilet 11 is a toilet bowl, but the toilet 11 may be a urinal. The toilet 11 may also be a floor-standing type or a wall-mounted type.

[0116] The measuring unit 21 may also be a gas sensor that analyzes the gas components in the stool, a weight sensor that measures the weight of the stool or urine, a water level sensor or water pressure sensor that measures the water level of the sealing water in the toilet bowl 11, or an acoustic analysis sensor that receives input from a microphone or vibration sensor for analyzing sound waves.

[0117] The network to which the toilet device 2, the server device 5, or the terminal 7 are connected may be a LAN (Local Area Network). The connection between the toilet device 2, the server device 5, or the terminal 7 and other components may be wired, wireless, or a combination of wired and wireless. The server device 5 may be connected to the terminal 7 via the communication unit 37 of the toilet device 2.

[0118] Furthermore, the communication connection method for transmitting the first identification information between the toilet device 2 and the terminal 7 may be short-range wireless communication such as NFC (Near Field Communication), which is a communication method provided in terminals 7 such as smartphones. The toilet device 2 may also be configured with an optical communication connection method in which the first identification information is encoded into a two-dimensional barcode, the two-dimensional barcode is displayed on a two-dimensional display provided in the toilet device 2, and the terminal 7 reads the two-dimensional barcode with a camera and decodes it into the first identification information. In the case of such short-range wireless communication or optical methods, the pairing operation between the toilet device 2 and the terminal 7 can be omitted, shortening operation time and improving convenience.

[0119] Furthermore, the server device 5 may be, for example, a cloud. The server device 5 may be configured as a single device, or may be configured as being distributed across multiple server devices 5. The server device 5 may be configured to be able to communicate with multiple terminals 7, not just one terminal 7.

[0120] Furthermore, the personal authentication information may be input, for example, by the operation device 23 of the toilet device 2, or by the operation unit 73 of the terminal 7, or may be transmitted to the toilet device 2 or the terminal 7 from a terminal other than the user's terminal 7. The input method may be, for example, key input, flick input, voice input, or image input. Furthermore, the authentication unit 57 may perform personal authentication (biometric authentication) based on biometric information such as the user's fingerprint, veins, weight, iris, vocal cords, face, anus, etc.

[0121] The authentication reception unit 31 may be located in the terminal 7 rather than the toilet device 2. The toilet device 2 does not perform personal authentication, but the terminal 7 receives personal authentication information. The terminal 7 may be, for example, an authentication reception unit 31 that receives authentication using a fingerprint or face authentication function provided on a smartphone, or by accessing a specific internet page and entering a personal ID and password. The personal authentication information may also be received by launching an application software installed on the smartphone. The server device 5 manages a list of users who can use the toilet device 2. The terminal 7 transmits the received personal authentication information to the server device 5, and the server device 5 compares the personal authentication information received from the terminal 7 with the user list to determine whether the user can use the toilet device 2. If the user is determined to be a user who can use the toilet device 2, the server device 5 transmits a notification of completion of personal authentication reception to the terminal 7, and the reception of the personal authentication information is completed.

[0122] Furthermore, the excrement measurement may be started manually by, for example, the operating device 23, or may be performed automatically. The automatic measurement may start simultaneously with the start of the excrement measurement. Alternatively, measurement may be performed continuously, for example, independent of the timing of the start of excrement measurement, and measurement data from the start to the end of excrement measurement may be distinguished from measurement data at times when excrement measurement is not being performed, transmitted to the communication unit 37, and excrement information may be generated based on the measurement data.

[0123] In the second embodiment, the authentication unit 57 determines whether the identification information received from the toilet device 2 matches the identification information received from the terminal 7, and stores the association between the excrement information and the personal authentication information. However, the method of associating the excrement information with the personal authentication information is not limited to whether the identification information matches. For example, the association may be performed based on the correlation between excrement information of a past user and the current excrement information.

[0124] Furthermore, step SP23 or step SP24 described in the second embodiment may be omitted, and step SP43 or step SP44 described in the fourth embodiment may be omitted.

[0125] Furthermore, in the third embodiment, the personal authentication information is transmitted from the terminal 7 to the server device 5 multiple times to redo the personal authentication, but after transmitting the personal authentication information from the terminal 7, different personal authentication information may be transmitted from the toilet device 2 or the remote control 9 to redo the personal authentication. For example, if incorrect personal authentication information is transmitted from the remote control 9 described in the fourth embodiment and the association between the incorrect personal authentication information and excrement information is stored in the memory unit 55 of the server device 5, correct personal authentication information may be transmitted from the terminal 7 to the server device 5, and the personal authentication may be redo, overwriting the association between the correct personal authentication information and excrement information.

[0126] In the third embodiment, the overwriting of associations is processed in the order in which they are received by the server device 5, so the last overwrite is valid. However, a priority order may be set to allow or prohibit overwriting. For example, priority information may be added to the association information of personal authentication information and excrement information. The priority information may be a priority rank indicated by a number from 1 to 5, for example, and may be stored together with the association information. When new association information is received, the priority information of the new association information is compared with the priority information of the already stored association information. If the new association has a higher priority rank, the new association is overwritten; if the new association has a lower priority rank, the new association is not overwritten. This allows special processing, such as eliminating associations of users who are completely unrelated to the toilet device 2, or having an administrator confirm the association on behalf of the user.

[0127] Furthermore, in the third embodiment, the process of transmitting a plurality of pieces of identification information from the server device 5 to the terminal 7 (step SP31) has been described. However, for example, one piece of identification information that satisfies a predetermined condition may be transmitted to the terminal 7.

[0128] In the fourth embodiment, the measurement unit 21 measures excrement based on the detection signal of the human body detection sensor 41, but the measurement unit 21 may start measuring excrement by pressing the user identification key 91. Furthermore, the measurement may start after personal authentication information is transmitted to the server device 5 by pressing the user identification key 91. [Explanation of symbols]
