In addition, the wireless communication unit 114 transmits a command signal output from the control unit 110 to the second wireless communication unit 62 of the toilet device 20.

[0066] The operation unit 116 accepts input of operation instructions from a user or the like. For example, a touch panel is used for the operation unit 116. For example, the operation unit 116 may be a mechanical switch or other sensor, or may be configured by a combination of these. The operation unit 116 is connected to the control unit 110. The operation unit 116 outputs the input operation instructions to the control unit 110. The control unit 110 controls the operation of each unit such as the wireless communication unit 114 in response to the operation instructions input from the operation unit 116, for example.

[0067] Display unit 118 displays various operation screens and the like. For example, a display device such as a liquid crystal display or an organic EL display is used for display unit 118. Display unit 118 is connected to control unit 110, and performs various displays based on the control of control unit 110. For example, when operation unit 116 is a touch panel, operation unit 116 is provided on top of display unit 118.

[0068] The speaker 120 outputs various sounds. The speaker 120 is connected to the control unit 110, and outputs various sounds based on the control of the control unit 110.

[0069] The microphone 122 converts the input sound into an electrical signal. The microphone 122 is connected to the control unit 110 and outputs the converted electrical signal to the control unit 110. Note that the toilet device 20 may be operated by the mobile information terminal 100 using voice information acquired by the microphone 122.

[0070] The acquisition unit 124 is a part that acquires the upper part of the setting label 150 and the use label 160. For example, when the setting label 150 and the use label 160 are QR codes (registered trademark), the acquisition unit 124 is an imaging device (camera). Also, for example, when the setting label 150 and the use label 160 are NFC tags, the acquisition unit 124 is a reading device. The acquisition unit 124 outputs the acquired information to the control unit 110.

[0071] The storage unit 112 stores a program 200 for remotely operating the functional units of the toilet device 20 by the mobile information terminal 100. In other words, the mobile information terminal 100 has the program 200 (application) installed therein for remote operation.

[0072] The control unit 110 reads the program 200 from the storage unit 112, for example, when the operation unit 116 instructs the control unit 110 to start the program 200. The control unit 110 then executes the operation of the remote operation mode based on the program 200, thereby enabling remote operation of the functional units of the toilet device 20.

[0073] Next, the initial setting work by the administrator will be described with reference to FIGS. FIG. 5 is an explanatory diagram showing the initial settings for establishing a communication connection between the toilet device and the mobile information terminal. FIG. 6 is an explanatory diagram of a case where a usage ID is linked to a toilet device. FIG. 7 is an explanatory diagram for setting operation buttons displayed on a portable information terminal. FIG. 8 is an explanatory diagram of a case where a test run is performed after the initial setting.

[0074] First, the administrator prepares the use label 160 and enters the toilet TR. Then, the administrator starts the remote control program 200 (application) stored in the storage unit 112. After that, as shown in FIG. 5, the setting label 150 is read by the acquisition unit 124 within the application. Alternatively, as shown in FIG. 5, the setting label 150 is read by the acquisition unit 124. This starts the remote control program 200 (application) stored in the storage unit 112. Note that if the application is not installed in the mobile information terminal 100, when the mobile information terminal 100 reads the setting label 150, the process may proceed to the application acquisition (download) step via the Internet.

[0075] The application program 200 has a control process for automatically transmitting the first identification information from the wireless communication unit 114 when the setting label 150 is acquired. Therefore, when the mobile information terminal 100 acquires the setting label 150, it transmits the first identification information stored in the setting label 150.

[0076] The control unit 40 of the toilet device 20 compares the first identification information transmitted from the mobile information terminal 100 with the first identification information stored in the storage unit 42. If the two pieces of identification information match, a wireless connection is established between the mobile information terminal 100 of the manager and the second wireless communication unit 62. The determination of whether or not to establish a wireless connection may be made by a control unit dedicated to controlling the second wireless communication unit 62.

[0077] 5, when a wireless connection with the second wireless communication unit 62 is established, the mobile information terminal 100 displays a setting screen (initial setting screen) on the display unit 118. That is, the program 200 installed in the mobile information terminal 100 executes an initial setting process for performing initial setting of the toilet device 20 when reading the setting label 150 in which the unique first identification information of the second wireless communication unit 62 is stored.

[0078] In this case, the wireless connection does not allow the mobile information terminal 100 to activate the functions of the toilet device 20. Therefore, even if a user reads the setting label 150 with his / her mobile information terminal 100 and attempts to establish a wireless connection with the second wireless communication unit 62, the functional units of the toilet device 20 cannot be activated.

[0079] 5, the setting screen displays, for example, a combination setting button 116a, a display setting button 116b, a test run button 116c, and an end button 116d. The combination setting button 116a is for setting a combination of a usage label 160 (second identification information) and the second wireless communication unit 62 to allow the user to use the remote operation mode. The display setting button 116b is for setting the type (mode) of the operation button displayed on the user's mobile information terminal 100. The test run button 116c is for the administrator to test run the remote operation mode after the initial settings are completed.

[0080] First, the administrator operates the combination setting button 116a. As a result, a screen for reading the use label 160 is displayed on the display unit 118 of the mobile information terminal 100, as shown in Fig. 6. Then, the administrator reads the use label 160 from the acquisition unit 124.

[0081] The storage unit 112 of the mobile information terminal 100 stores a program 200 that automatically transmits a write signal for the second identification information from the wireless communication unit 114 when the label for use 160 is acquired. Therefore, when the label for use 160 is acquired, the mobile information terminal 100 transmits the second identification information stored in the label for use 160. That is, the program 200 installed in the mobile information terminal 100 executes a combination step of transmitting a write signal for the second identification information when the label for use 160 in which the changeable second identification information of the second wireless communication unit 62 is stored is read during the initial setting step. Note that the write signal for the second identification information is not limited to being transmitted automatically, and may be transmitted based on the operation of the administrator.

[0082] The control unit 40 of the toilet device 20 stores the received second identification information in the storage unit 42. If different second identification information is stored in the storage unit 42, the second identification information is rewritten (overwritten) to the new second identification information. This allows the usage label 160 and the second wireless communication unit 62 to be paired (linked) with each other.

[0083] When the control unit 40 stores the second identification information in the memory unit 42, it causes the second wireless communication unit 62 to transmit a combination completion signal. When the control unit 110 of the mobile information terminal 100 receives the combination completion signal, it causes the display unit 118 to display, for example, "Setting of combination of toilet device and usage ID completed" as shown in Fig. 6. Then, when the confirmation button 116e is operated, the control unit 110 of the mobile information terminal 100 returns the display unit 118 to the setting screen in Fig. 5.

[0084] When the second identification information is stored, the second wireless communication unit 62 sets both the first identification information and the second identification information as its own identification information. Then, the second wireless communication unit 62 constantly outputs the first identification information and the second identification information stored in the storage unit 42.

[0085] Next, the administrator operates the display setting button 116b. As a result, as shown in FIG. 7, a screen for setting the display of operation buttons for operating the functional parts of the toilet device 20 is displayed on the display unit 118 of the mobile information terminal 100. In this example, whether or not to display the flush button 116g (see FIG. 8) is set. For example, if the toilet device 20 has an automatic flushing function that automatically flushes flushing water when the human body detection sensor 51 or the seating detection sensor 53 changes from a human body detection state to a non-detection state, the display of the flush button 116g may be set to "none." Note that the setting of whether or not to display the operation button is not limited to the flush button 116g, and may be for other operation buttons.

[0086] The administrator operates the send button 116f after configuring the display settings. This causes the control unit 110 of the mobile information terminal 100 to transmit a setting signal for the display settings from the wireless communication unit 114. Upon receiving the setting signal, the control unit 40 of the toilet device 20 stores the setting contents in the storage unit 42 and causes the second wireless communication unit 62 to transmit a setting completion signal.

[0087] When the control unit 110 of the portable information terminal 100 receives the setting completion signal, it causes the display unit 118 to display the fact that the setting has been completed. Then, when the confirmation button 116e is operated, the control unit 110 of the portable information terminal 100 returns the display unit 118 to the setting screen in FIG.

[0088] Next, the administrator operates the test run button 116c. As a result, a screen for reading the usage label 160 is displayed on the display unit 118 of the mobile information terminal 100 as shown in Fig. 8. Note that if the end button 116d is operated on the setting screen without performing a test run, a screen prompting a test run may be displayed on the display unit 118 as shown in Fig. 8.

[0089] Then, the administrator reads the use label 160 from the acquisition unit 124. The storage unit 112 of the mobile information terminal 100 stores a program 200 that automatically transmits the second identification information from the wireless communication unit 114 when the use label 160 is acquired. Therefore, when the mobile information terminal 100 acquires the use label 160, it transmits a connection request signal having the second identification information stored in the use label 160.

[0090] The control unit 40 of the toilet device 20 compares the second identification information of the connection request signal transmitted from the mobile information terminal 100 with the second identification information stored in the storage unit 42. If the two pieces of identification information match, the control unit 40 executes a wireless connection step of establishing a wireless connection between the mobile information terminal 100 and the second wireless communication unit 62.

[0091] In addition to the comparison of the second identification information, the control unit 40 may compare the first identification information to determine whether or not a wireless connection is established. Specifically, for example, the second identification information of the connection request signal transmitted from the mobile information terminal 100 is compared with the second identification information stored in the storage unit 42, and when both identification information match, the mobile information terminal 100 and the control unit 40 communicate with each other. At that time, the control unit 40 transmits the first identification information to the mobile information terminal 100. The mobile information terminal 100 transmits the first identification information received from the control unit 40 to the control unit 40. The control unit 40 determines whether or not the first identification information received from the mobile information terminal 100 matches the first identification information stored in the storage unit 42. Then, when the first identification information matches, the control unit 40 establishes a wireless connection between the mobile information terminal 100 and the second wireless communication unit 62. In this case, the comparison of the first identification information may be configured to be performed by the mobile information terminal 100.

[0092] When the wireless connection is established, the control unit 40 causes the second wireless communication unit 62 to transmit a connection permission signal. The connection permission signal includes information related to the display settings stored in the storage unit 42. As shown in FIG. 8, when the control unit 110 of the mobile information terminal 100 receives the connection permission signal, the control unit 110 causes the display unit 118 to display a display of operation buttons (operation screen) based on the information related to the display settings. The connection request signal may be transmitted from the second wireless communication unit 62 of the toilet device 20. In that case, for example, the connection request signal is constantly transmitted from the toilet device 20, and when the mobile information terminal 100 acquires the usage label 160, the second identification information acquired by the mobile information terminal 100 is compared with the second identification information stored in the storage unit 42.

[0093] In this example, in addition to the flush button 116g, the display unit 118 displays a rear cleansing button 116h, a bidet cleansing button 116i, an onomatopoeic sound generating button 116j, and the like. If the display setting described above is set to "no display" of the flush button 116g, the connection permission signal includes a signal to "no display" of the flush button 116g. In such a case, the flush button 116g will not be displayed on the display unit 118.

[0094] Then, the manager operates, for example, the posterior washing button 116h. The control unit 110 of the mobile information terminal 100 transmits a command signal for posterior washing to the second wireless communication unit 62. Upon receiving the command signal for posterior washing, the control unit 40 of the toilet device 20 actuates the nozzle driving device 75 to advance the nozzle 30 into the bowl portion 12.

[0095] This allows the manager to confirm that the label for use 160 and the second wireless communication unit 62 have been properly combined. The manager operates the disconnect button 116k to disconnect the wireless connection with the second wireless communication unit 62. Finally, the manager attaches the label for use 160 to a wall surface or the like of the toilet room TR, completing the initial setting. Note that the initial setting may be performed by a contractor or a maintenance company instead of the manager.

[0096] Next, a case where a user operates the functional parts of the toilet device 20 using his / her mobile information terminal 100 will be described. FIG. 9 is an explanatory diagram of a case where a user who has entered the toilet room operates the toilet device using a mobile information terminal.

[0097] First, a user who has entered the toilet room TR starts the remote control program 200 (application) stored in the storage unit 112. Thereafter, as shown in FIG. 9, the acquisition unit 124 reads the use label 160 within the application. Alternatively, a user who has entered the toilet room TR reads the use label 160 by the acquisition unit 124 as shown in FIG. 9. This starts the remote control program 200 (application) stored in the storage unit 112. Note that if the application is not installed in the user's mobile information terminal 100, when the mobile information terminal 100 reads the use label 160, the process may proceed to the application acquisition (download) step via the Internet.

[0098] The application program 200 has a control process for automatically transmitting the second identification information and its own device identification information from the wireless communication unit 114 when the use label 160 is acquired. Therefore, when the mobile information terminal 100 acquires the use label 160, it transmits a connection request signal having the second identification information stored in the use label 160. That is, when the program 200 installed in the mobile information terminal 100 reads the use label 160, it executes a connection request step of transmitting a connection request signal having the second identification information to request a wireless connection.

[0099] The control unit 40 of the toilet device 20 compares the second identification information of the connection request signal transmitted from the mobile information terminal 100 with the second identification information stored in the storage unit 42. Then, when both pieces of identification information match, the control unit 40 establishes a wireless connection between the mobile information terminal 100 and the second wireless communication unit 62.

[0100] In addition to the comparison of the second identification information, the control unit 40 may compare the first identification information to determine whether or not a wireless connection is established. Specifically, for example, the second identification information of the connection request signal transmitted from the mobile information terminal 100 is compared with the second identification information stored in the storage unit 42, and when both identification information match, the mobile information terminal 100 and the control unit 40 communicate with each other. At that time, the control unit 40 transmits the first identification information to the mobile information terminal 100. The mobile information terminal 100 transmits the first identification information received from the control unit 40 to the control unit 40. The control unit 40 determines whether or not the first identification information received from the mobile information terminal 100 matches the first identification information stored in the storage unit 42. Then, when the first identification information matches, the control unit 40 establishes a wireless connection between the mobile information terminal 100 and the second wireless communication unit 62. In this case, the comparison of the first identification information may be configured to be performed by the mobile information terminal 100.

[0101] When the wireless connection is established, the control unit 40 causes the second wireless communication unit 62 to transmit a connection permission signal. The connection permission signal includes information related to the display settings stored in the storage unit 42. As shown in FIG. 9, when the control unit 110 of the mobile information terminal 100 receives the connection permission signal, it causes the display unit 118 to display the display of operation buttons based on the information related to the display settings. That is, the program 200 installed in the mobile information terminal 100 causes the display unit 118 to execute a use step of displaying the operation buttons of the functional units of the toilet device 20 when the connection permission signal transmitted from the second wireless communication unit 62 is received.

[0102] For example, when the flush button 116g is operated, the control unit 110 of the mobile information terminal 100 transmits a command signal for flushing the toilet. Based on the command signal for flushing the toilet, the control unit 40 operates the toilet flushing device 79 to flush the toilet 10. In this way, the user can operate various functional units of the toilet device 20 using his / her mobile information terminal 100 by operating various operation buttons displayed on the display unit 118.

[0103] When the user wishes to end use of the toilet device 20, the user operates the disconnect button 116k. This causes the wireless connection between the user's mobile information terminal 100 and the second wireless communication unit 62 to be released (wireless communication to be disconnected). In this case, when the wireless connection is released, the mobile information terminal 100 may be notified (displayed) that communication has been disconnected.

[0104] The wireless connection between the mobile information terminal 100 and the second wireless communication unit 62 may be released when a predetermined time has elapsed since the wireless connection was established. In this case, the elapse of the predetermined time may be measured by a timer in the mobile information terminal 100 or may be measured by a timer in the toilet device 20. In addition, the wireless connection may be released when the user moves a predetermined distance away from the toilet room TR using a pedometer in the mobile information terminal 100 or the radio wave intensity between the mobile information terminal 100 and the second wireless communication unit 62. This makes it possible to prevent the wireless connection between the mobile information terminal 100 and the second wireless communication unit 62 from continuing for a long time. Therefore, for example, in a public toilet 1, an unspecified number of users can use the toilet system 5 using their own mobile information terminals 100.

[0105] Next, the control processes of the setting mode and the mobile information terminal use mode executed by the control unit 40 of the toilet device 20 will be described. Fig. 10 is a flow chart showing the control of the setting mode and the mobile information terminal use mode executed by the control unit of the toilet device. The control process shown in Fig. 10 is stored in advance in the storage unit 42. The control process shown in Fig. 10 is repeatedly executed at a predetermined cycle after the toilet device 20 is powered on. In Fig. 10, each step is indicated by "S".

[0106] 10 are setting modes in which the control unit 40 associates the use label 160 with the second wireless communication unit 62. S4 and S5 in Fig. 10 are mobile information terminal use modes in which the user's mobile information terminal 100 is wirelessly connected to the second wireless communication unit 62 after the use label 160 is associated with the second wireless communication unit 62.

[0107] First, in S1, it is determined whether or not a write signal for the second identification information has been received. That is, after the mobile information terminal 100 reads the setting label 150, the control unit 40 reads the usage label 160 and determines whether or not a write signal for the second identification information has been transmitted. Then, if it is determined that "YES" in S1, that is, that a write signal for the second identification information has been received, the process proceeds to S2. On the other hand, if it is determined that "NO" in S1, that is, that a write signal for the second identification information has not been received, the process proceeds to S4.

[0108] In S2, the second identification information is written. That is, the control unit 40 writes (overwrites) the received second identification information in the storage unit 42. As a result, the identification information of the second wireless communication unit 62 becomes the second identification information in addition to the first identification information. That is, the control unit 40 has a setting mode in which the second identification information is stored when a write signal for the second identification information is received.

[0109] In the next step S3, the first identification information and the second identification information are output. That is, the control unit 40 causes the second wireless communication unit 62 to output both the first identification information and the second identification information. This ends the setting mode in which the second identification information is set in the second wireless communication unit 62.

[0110] S4 and S5 are for cases where the administrator performs a test run or where the user uses his / her mobile information terminal 100. If it is performed by the user, the process moves to S4 with "NO" in S1. On the other hand, if it is a test run by the administrator, the process moves from S3 to S4.

[0111] In S4, it is determined whether the second identification information of the received connection request signal matches the second identification information stored in the storage unit 42. That is, the control unit 40 monitors the reception of the second identification information written in the storage unit 42 in S2. Then, if the result of S4 is "YES", that is, the control unit 40 determines that the second identification information of the received connection request signal matches the second identification information stored in the storage unit 42, the process proceeds to S5. On the other hand, if the result of S4 is "NO", that is, the control unit 40 determines that the second identification information of the received connection request signal does not match the second identification information stored in the storage unit 42, the process ends. That is, the control unit 40 has a mobile information terminal use mode that wirelessly connects the second wireless communication unit 62 and the mobile information terminal 100 when the stored second identification information is received.

[0112] In S5, a connection permission signal is transmitted. That is, when the control unit 40 establishes a wireless connection between the mobile information terminal 100 and the second wireless communication unit 62, the control unit 40 transmits the connection permission signal to the mobile information terminal 100, and ends the process. When the mobile information terminal 100 receives the connection permission signal, an operation screen is displayed on the display unit 118. After that, the control unit 40 operates the functional units of the toilet device 20 based on a command signal transmitted from the connected mobile information terminal 100.

[0113] The toilet system 5 according to this embodiment includes a toilet device 20 having a second wireless communication unit 62 capable of communicating with a mobile information terminal 100 and a control unit 40 that controls the second wireless communication unit 62, a setting label 150 that stores first identification information unique to the second wireless communication unit 62 and is readable by the mobile information terminal 100, and a usage label 160 that stores second identification information that can be changed for the second wireless communication unit 62 and is readable by the mobile information terminal 100. When the second wireless communication unit 62 and the mobile information terminal 100 are wirelessly connected based on the first identification information, the control unit 40 stores the second identification information when it receives the second identification information transmitted from the mobile information terminal 100.

[0114] The first identification information of the second wireless communication unit 62 is unique (unchangeable). Therefore, for example, in the case where the user's mobile information terminal 100 and the second wireless communication unit 62 are wirelessly connected only by the setting label 150, if the setting label 150 is damaged or lost, a corresponding setting label 150 must be prepared. That is, until the setting label 150 is prepared, the functional unit of the toilet device 20 cannot be operated using the mobile information terminal 100. As a result, the second wireless communication unit 62 and the setting label 150 must be appropriately managed. In addition, it may take time to prepare a new setting label 150. Therefore, the usability of the toilet system 5 may be deteriorated.

[0115] Therefore, the toilet system 5 according to this embodiment uses changeable (overwritable) second identification information in addition to the first identification information for the second wireless communication unit 62. In the toilet system 5, the setting label 150 storing the first identification information is for the administrator, and the usage label 160 storing the second identification information is for the user. In other words, the usage label 160 is highly versatile and can be used for multiple second wireless communication units 62. As a result, even if the usage label 160 is damaged or lost, for example, the toilet system 5 can be used with a new usage label 160.

[0116] Furthermore, the toilet system 5 according to this embodiment uses changeable (overwritable) second identification information in addition to the first identification information in the second wireless communication unit 62. As a result, even if the usage label is intentionally lost for the purpose of mischief (for example, a person other than the user uses the usage label to establish a wireless connection and operate a functional unit of the toilet device regardless of the user's intention), a new usage label 160 can use second identification information different from the original (before-loss) second identification information, and thus mischief can be suppressed.

[0117] Furthermore, when the control unit 40 receives the stored second identification information, it wirelessly connects the second wireless communication unit 62 to the mobile information terminal 100 that transmitted the second identification information. This allows the toilet system 5 to wirelessly connect the second wireless communication unit 62 to the mobile information terminal 100 using the changeable second identification information. Therefore, even if the currently used label for use 160 becomes unusable, the toilet system 5 can be quickly made available for use by using a new label for use 160.

[0118] In the above-described embodiment, an example has been described in which the control unit 40 of the toilet device 20 determines whether a wireless connection between the toilet device 20 (second wireless communication unit 62) and the mobile information terminal 100 is established. However, as in the modified examples shown in Figs. 11 and 12, the determination of whether a wireless connection between the toilet device 20 (second wireless communication unit 62) and the mobile information terminal 100 is established may be made by the mobile information terminal 100.

[0119] FIG. 11 is a flowchart showing the write control of the second identification information executed by the control unit of the portable information terminal according to the modified example. FIG. 12 is a flowchart showing connection establishment control using a label for use executed by a control unit of a portable information terminal according to a modified example. The control processes shown in Fig. 11 and Fig. 12 are stored in advance in the storage unit 112 of the mobile information terminal 100. The control processes shown in Fig. 11 and Fig. 12 are repeatedly executed at a predetermined cycle. In Fig. 11 and Fig. 12, each step is indicated by "S".

[0120] First, a case where the administrator associates the usage label 160 (second identification information) with the toilet device 20 (second wireless communication unit 62) will be described with reference to FIG.

[0121] The manager prepares the use label 160 and enters the toilet TR. Then, the manager starts the remote control program 200 (application) stored in the storage unit 112. When the setting label 150 is read by the acquisition unit 124 within the application, the remote control program 200 (application) stored in the storage unit 112 may be started. If the application is not installed in the mobile information terminal 100, when the setting label 150 is read by the mobile information terminal 100, the process may proceed to the acquisition (download) of the application via the Internet.

[0122] In S11, the first identification information is acquired. That is, the administrator reads the setting label 150 in which the first identification information is stored, by the acquisition unit 124 of the mobile information terminal 100. The control unit 110 of the mobile information terminal 100 stores the acquired first identification information in the storage unit 112.

[0123] In the next S12, it is determined whether or not the first identification information transmitted from the second wireless communication unit 62 has been received. The second wireless communication unit 62 constantly outputs (transmits) the first identification information after the toilet device 20 is powered on. Therefore, if the mobile information terminal 100 is within the detection range of the second wireless communication unit 62, it will receive the first identification information.

[0124] Then, if the result of S12 is "YES", that is, if it is determined that the first identification information has been received, the process proceeds to S13. On the other hand, if the result of S12 is "NO", that is, if it is determined that the first identification information has not been received, the process ends.

[0125] In the next step S13, it is determined whether the acquired first identification information matches the received first identification information. That is, the control unit 110 compares the first identification information stored in the storage unit 112 with the received first identification information.

[0126] Then, if S13 returns "YES", that is, if it is determined that the acquired first identification information matches the received first identification information, the process proceeds to S14. On the other hand, if S13 returns "NO", that is, if the acquired first identification information does not match the received first identification information, the process ends. If the first identification information does not match, for example, it may be the case that the first identification information of the second wireless communication unit 62 installed in another toilet room TR is received. In S12 and S13, the mobile information terminal 100 monitors the reception of the first identification information for a predetermined time after reading the setting label 150, for example.

[0127] In S14, a wireless connection is established between the portable information terminal 100 and the second wireless communication unit 62. That is, when the received first identification information matches the first identification information stored in the storage unit 112, the control unit 110 establishes a wireless connection between the portable information terminal 100 and the second wireless communication unit 62.

[0128] When a wireless connection with the second wireless communication unit 62 is established, the control unit 110 causes the display unit 118 to display a setting screen (see FIG. 5). That is, the program 200 installed in the mobile information terminal 100 causes the mobile information terminal 100 to execute an initial setting process for performing initial setting of the toilet device 20 when the mobile information terminal 100 reads the setting label 150 in which the unique first identification information of the second wireless communication unit 62 is stored.

[0129] When the combination setting button 116a is selected in the initial setting process (setting screen), the control unit 110 causes the display unit 118 to display a screen for reading the label for use 160. In S15, the second identification information is acquired. That is, the administrator causes the acquisition unit 124 of the mobile information terminal 100 to read the label for use 160 in which the second identification information is stored. The control unit 110 of the mobile information terminal 100 causes the memory unit 112 to store the acquired second identification information.

[0130] In the next S16, a signal for writing the second identification information is transmitted. A program 200 is stored in the memory unit 112 of the mobile information terminal 100, which causes the wireless communication unit 114 to automatically transmit a signal for writing the second identification information when the label for use 160 is acquired. Therefore, when the label for use 160 is acquired, the mobile information terminal 100 transmits the second identification information stored in the label for use 160.

[0131] That is, the program 200 installed in the mobile information terminal 100 executes a combination process of transmitting a write signal for the second identification information when the usage label 160 storing the changeable second identification information of the second wireless communication unit 62 is read during the initial setting process.

[0132] The signal for writing the second identification information is not limited to being sent automatically, but may be sent based on the operation of the administrator. After sending the signal for writing the second identification information, the control unit 110 returns the display unit 118 to the setting screen, and the process ends.

[0133] The control unit 40 of the toilet device 20 stores the received second identification information in the storage unit 42. If different second identification information is stored in the storage unit 42, it is rewritten (overwritten) with the new second identification information. This allows the usage label 160 and the second wireless communication unit 62 to be paired (linked). When the second identification information is stored in the second wireless communication unit 62, both the first identification information and the second identification information are set as its own identification information. Then, the second wireless communication unit 62 constantly outputs the first identification information and the second identification information.

[0134] When the control unit 40 stores the second identification information in the memory unit 42, it may cause the second wireless communication unit 62 to transmit a combination completion signal. When the control unit 110 of the mobile information terminal 100 receives the combination completion signal, it may cause the display unit 118 to display, for example, "Setting of the combination of the toilet device and the usage ID completed." Then, the control unit 110 of the mobile information terminal 100 may return the display unit 118 to the setting screen when the confirmation button 116e is operated.

[0135] Next, a case where a user operates the functional units of the toilet device 20 using his / her mobile information terminal 100 will be described with reference to Fig. 12. Note that the same control process is performed for a test run by an administrator.

[0136] First, a user who has entered the toilet room TR starts the remote control program 200 (application) stored in the storage unit 112. Alternatively, the remote control program 200 (application) stored in the storage unit 112 may be started by reading the use label 160 by the acquisition unit 124 within the application. If the application is not installed in the user's mobile information terminal 100, when the use label 160 is read by the mobile information terminal 100, a process of acquiring (downloading) the application via the Internet may be started.

[0137] In S21, the second identification information is acquired. That is, the user reads the usage label 160 attached to the wall surface or the like of the toilet room TR with the acquisition unit 124 of the mobile information terminal 100. The control unit 110 of the mobile information terminal 100 stores the acquired second identification information in the storage unit 112.

[0138] In S22, it is determined whether or not the second identification information transmitted (output) from the second wireless communication unit 62 has been received. When the second identification information is linked to the toilet device 20 (second wireless communication unit 62) by the administrator, the second wireless communication unit 62 constantly outputs (transmits) the first identification information and the second identification information. Therefore, when the mobile information terminal 100 enters the detection range of the second wireless communication unit 62, it receives the second identification information.

[0139] Then, if the result of S22 is "YES", that is, if it is determined that the second identification information has been received, the process proceeds to S23. On the other hand, if the result of S22 is "NO", that is, if it is determined that the second identification information has not been received, the process ends.

[0140] In the next step S23, it is determined whether the acquired second identification information matches the received second identification information. That is, the control unit 110 compares the second identification information stored in the storage unit 112 with the received second identification information.

[0141] Then, if S23 returns "YES", that is, if it is determined that the acquired second identification information matches the received second identification information, the process proceeds to S24. On the other hand, if S23 returns "NO", that is, if the acquired second identification information does not match the received second identification information, the process ends. If the second identification information does not match, for example, the second identification information of the second wireless communication unit 62 installed in another toilet room TR is received, or the second identification information not linked to the toilet room TR is received. In S22 and S23, the mobile information terminal 100 monitors the reception of the second identification information for a predetermined time after reading the usage label 160, for example.

[0142] In S24, a wireless connection is established between the mobile information terminal 100 and the second wireless communication unit 62. That is, when the control unit 110 reads the usage label 160 storing the changeable second identification information of the second wireless communication unit 62, the control unit 110 executes a connection establishment step for establishing a connection with the second wireless communication unit 62. Specifically, when the received second identification information matches the second identification information stored in the storage unit 112, the control unit 110 establishes a wireless connection between the mobile information terminal 100 and the second wireless communication unit 62.

[0143] In addition to the comparison of the second identification information, the control unit 110 may compare the first identification information to determine whether or not a wireless connection has been established. Specifically, for example, when the received second identification information matches the second identification information stored in the storage unit 112, the mobile information terminal 100 and the control unit 40 communicate with each other. At that time, the control unit 40 causes the mobile information terminal 100 to transmit the first identification information and information obtained by encrypting the first identification information. Based on the first identification information received from the control unit 40, the control unit 110 encrypts it in the same manner as the control unit 40. Then, the control unit 110 determines whether or not the encrypted information matches the information obtained by encrypting the first identification information received from the control unit 40. Then, when the first identification information matches, the control unit 110 causes the mobile information terminal 100 to establish a wireless connection with the second wireless communication unit 62. In this case, the comparison of the first identification information may be performed by the control unit 40.

[0144] When a wireless connection with the second wireless communication unit 62 is established, the control unit 110 causes the display unit 118 to display operation buttons (see FIG. 9) for operating the functional units of the toilet device 20. That is, the program 200 installed in the mobile information terminal 100 causes the display unit 118 to execute a use step of displaying operation buttons for the functional units of the toilet device 20 when a wireless connection with the second wireless communication unit 62 is established.

[0145] The operation buttons displayed on the display unit 118 are displayed in a mode set by the administrator through display settings in the initial process. Therefore, the control unit 110 causes the display unit 118 to display the operation buttons based on a command signal for display settings transmitted from the second wireless communication unit 62.

[0146] In this case, while the wireless connection with the second wireless communication unit 62 is being established (during S23), the mobile information terminal 100 may receive a command signal having information regarding the display settings from the second wireless communication unit 62. Furthermore, when the wireless communication connection between the mobile information terminal 100 and the second wireless communication unit 62 is established, a command signal having information regarding the display settings may be transmitted from the second wireless communication unit 62, and the mobile information terminal 100 may receive the command signal.

[0147] This allows the user to operate various functional parts of the toilet device 20 with their own mobile information terminal 100. For example, when the flush button 116g is operated, a command signal for flushing the toilet is sent from the mobile information terminal 100. Based on the command signal for flushing the toilet, the control unit 40 operates the toilet flushing device 79 to flush the toilet 10.

[0148] In the above-described embodiment, an example has been described in which the administrator connects to the second wireless communication unit 62 via the setting label 150 to perform the initial settings. However, this embodiment is not limited to this, and the initial settings may be performed, for example, by connecting a mobile information terminal owned by the administrator to the toilet device via a wire. Also, the initial settings may be performed via the Internet from a location away from the toilet TR (for example, a management room). In such cases, the setting label 150 storing the first identification information is not necessary.

[0149] In the above embodiment, the second identification information is written by reading the setting label 150. However, the present embodiment is not limited to this, and the second identification information may be written by, for example, an input operation from a mobile information terminal owned by the administrator.

[0150] The second identification information may also include specific command information. For example, the second identification information may include command information for prohibiting the operation of the functional units of the toilet device 20, or command information for prohibiting overwriting that can only be overwritten by the specific second identification information. This allows the administrator to, for example, temporarily prohibit the use of the toilet system 5. Then, only the specific administrator can restore the toilet system 5.

[0151] Also, for example, the second identification information may include information for transitioning to an operation screen for elderly people. This allows, for example, the user to select an operation screen on his / her mobile information terminal. Also, the first identification information or the second identification information may be encrypted.

[0152] The embodiment may include the following features.
