When constructing a network with the network device 20, the communication device 15 receives a first pairing command signal transmitted from the command device 25, or communicates with the network device 20 after the network is constructed. That is, the communication device 15 has two communication units (reception units) capable of receiving the signal from the command device 25 and the signal from the network device 20. The command device 25 is a device for shifting the communication device 15 to the pairing mode. The first pairing command signal constitutes the pairing command signal of the present invention. The communication device 15 has a first communication unit 16, a second communication unit 17, a control unit 18, and a storage unit 19.

For example, the control unit 18 stores the first pairing command signal received by the reception unit 16a of the first communication unit 16 in the storage unit 19, or the transmission unit 16b of the first communication unit 16 to the control unit 13 of the device main body 11. It is transmitted that there is a first pairing command signal toward. Further, the control unit 18 shifts the communication device 15 to the pairing mode by the first pairing command signal transmitted from the command device 25 and the pairing permission signal transmitted from the control unit 13 of the device main body 11. ..

The storage unit 19 is a memory that stores the first pairing command signal received by the reception unit 16a of the first communication unit 16, the signal transmitted and received by the second communication unit 17, and the like. Further, the storage unit 19 stores the identification information of the paired network device 20. This identification information is individually set for the network device 20. Further, the storage unit 19 stores a control program executed by the control unit 18. The storage unit 19 may be provided in the control unit 18.

The network device 20 is arranged, for example, in a public toilet room TR, a toilet room in a building, a hotel unit bath, a public bath, or the like, and one is provided for each of a plurality of water-related devices 10. The network device 20 is connected to a plurality of water peripheral devices 10 by the network 35, and communicates information about each water peripheral device 10 with the external device 40 and the communication device 15. The network device 20 has a communication unit 21, a control unit 22, and a storage unit 23.

The communication unit 21 is connected to the setting device 27, and has a receiving unit 21a for receiving the second pairing command signal transmitted from the setting device 27, a transmitting unit 21b for transmitting the identification information of the network device 20, and the transmission unit 21b. have.

And send the identification information of. Further, the control unit 22 shifts the network device 20 to the pairing mode by the second pairing command signal transmitted from the setting device 27.

The storage unit 23 is a memory that stores the second pairing command signal received by the reception unit 21a of the communication unit 21, the signal transmitted and received by the communication unit 21, and the like. Further, the storage unit 23 stores the identification information of the communication device 15 of the paired water supply device 10. This identification information is individually set for each communication device 15. Further, the storage unit 23 stores a control program executed by the control unit 22. The storage unit 23 may be provided in the control unit 22.

The command device 25 transmits a first pairing command signal for pairing the communication device 15 and the network device 20 to the communication device 15. That is, the command device 25 is for shifting the communication device 15 of the water supply device 10 to the pairing mode. The command device 25 is, for example, a remote controller owned by an administrator who manages the water supply device 10.

The command device 25 transmits the first pairing command signal to the communication device 15 according to the first communication standard. The first communication standard is, for example, one-way communication from the command device 25 to the communication device 15. Further, the first communication standard enables communication without pairing with the communication device 15. That is, in the first communication standard, the communication protocol between the command device 25 and the communication device 15 of each water supply device 10 is the same.

Therefore, each communication device 15 within the radio wave range of the command device 25 can simultaneously receive the first pairing command signal transmitted from the command device 25. Further, one command device 25 can shift the communication device 15 of each water supply device 10 to the pairing mode without preparing a dedicated command device for each communication device 15 of each water supply device 10. That is, the first pairing command signal is a signal common to each communication device 15. In other words, the first communication standard is a method in which each communication device 15 determines a signal from the command device 25.

On the other hand, the communication between the network device 20 and each communication device 15 is based on the second communication standard whose communication protocol is different from that of the first communication standard. The second communication standard is that bidirectional communication between the network device 20 and the communication device 15 is possible by performing pairing (network construction), for example, and information communication is possible until pairing (network construction) is performed. It cannot be done. Therefore, each communication device 15 can receive communication having two different communication protocols.

The setting device 27 transmits a second pairing command signal for pairing the communication device 15 and the network device 20 to the network device 20. That is, the setting device 27 is for shifting the network device 20 to the pairing mode. The setting device 27 is, for example, a tablet terminal owned by an administrator who manages the water supply device 10. The setting device 27 is not limited to the tablet terminal, and may be, for example, a switch provided in the network device 20.

Further, the control process shown in FIG. 3 is stored in advance in the storage unit 19 of the communication device 15. The control process shown in FIG. 4 is stored in advance in the storage unit 14 of the device main body 11. The control process shown in FIG. 5 is stored in advance in the storage unit 23 of the network device 20.

In S1, it is determined whether or not the first pairing command signal is received from the command device 25. That is, the control unit 18 determines whether or not the receiving unit 16a has received the first pairing command signal.

Then, "YES" in S1, that is, when the control unit 18 determines that the first pairing command signal has been received, the storage unit 19 stores the first pairing command signal and proceeds to S2. On the other hand, if it is determined in S1 that "NO", that is, the control unit 18 has not received the first pairing command signal, the end is set.

In S2, it is transmitted that the control unit 13 of the device main body 11 has the first pairing command signal. That is, the control unit 18 transmits a control signal that the first pairing command signal has been received to the control unit 13 of the device main body 11.

In the next S3, it is determined whether or not the pairing permission signal is received from the control unit 13 of the device main body 11. The pairing permission signal transmitted by the control unit 13 is executed based on the control process of FIG. The control in which the control unit 13 transmits the pairing permission signal to the control unit 18 of the communication device 15 will be described later.

Then, when "YES" in S3, that is, the control unit 18 determines that the pairing permission signal has been received, the process proceeds to S4. On the other hand, "NO" in S3. That is, if the control unit 18 determines that the pairing permission signal has not been received, the end is set.

In S4, it shifts to the pairing mode. That is, the control unit 18 shifts to a state of accepting the identification information of the network device 20 in order to perform pairing with the network device 20. The pairing mode is continued for a predetermined time (for example, 3 to 10 minutes). The control unit 18 transmits the identification information of the communication device 15 to the network device 20 during the pairing mode.

In S5, it is determined whether or not the identification information of the network device 20 has been received. That is, the control unit 18 determines whether or not the network device 20 has received the transmitted identification information of the network device 20 by shifting to the pairing mode. The pairing control in which the network device 20 shifts to the pairing mode is executed based on the control process of FIG. The control process of FIG. 5 will be described later.

Then, if "YES" in S5, that is, the control unit 18 determines that the identification information of the network device 20 has been received, the process proceeds to S6. On the other hand, if "NO" in S5, that is, the control unit 18 determines that the identification information of the network device 20 has not been received, the identification information of the network device 20 is monitored for the predetermined time (for example, 3 to 10 minutes). When this predetermined time has elapsed, the pairing mode is canceled and the end is set.

In the next S6, the identification information of the network device 20 is stored. That is, the control unit 18 stores the identification information of the network device 20 in the storage unit 19 and serves as an end.

Next, the pairing control process executed by the control unit 13 of the device main body 11 will be described with reference to FIG.

In S11, it is determined whether or not the presence of the pairing command signal is received from the communication device 15. That is, the control unit 13 determines whether or not the communication device 15 has received the first pairing command signal from the command device 25.

Then, if "YES" in S11, that is, the control unit 13 determines that the pairing command signal is received from the communication device 15, the process proceeds to S12. That is, "YES" in S11 is made based on S2 in FIG. On the other hand, if it is determined in S11 that "NO", that is, the control unit 13 has not received the pairing command signal from the communication device 15, the end is set.

In S12, it is determined whether or not the water supply device 10 is in the second state. That is, the control unit 13 is either in the first state in which the water supply device 10 does not allow pairing or in the second state in which the water supply device 10 is switched from the first state by the switching operation to the water supply device 10 and allows pairing. Judge whether it is.

Here, the second state in which pairing is permitted means a state in which at least one of the devices and sensors provided in the water supply device 10 is operated (operated) by an administrator or the like. That is, the first state is a standby state in which the water supply device 10 (device main body 11) is on standby, and the second state is a state in which the water supply device 10 (device main body 11) is switched from the first state by a switching operation.

The second state means, for example, a state in which the human body detection unit 12 detects a human body (administrator) or a state in which an operation switch for operating the function of the water supply device 10 is operated. As an example, in the case of a warm water washing toilet seat, the second state can be a state in which the seating sensor serving as the human body detection unit 12 detects the seating of the toilet seat. Further, in the case of a urinal, the radio wave sensor serving as the human body detection unit 12 can be in a state of detecting the human body in front of the urinal. Further, the automatic faucet, the electric water heater, the auto soap dispenser, the hand drying device, and the like can be in a state where the photoelectric sensor serving as the human body detecting unit 12 detects the human body (hand).

Then, "YES" in S12, that is, when the control unit 13 determines that the water supply device 10 is in the second state, the process proceeds to S13. On the other hand, if "NO" in S12, that is, the control unit 13 determines that the water supply device 10 is in the first state, the end is set. That is, the control unit 13 refuses to shift the communication device 15 to the pairing mode when the water supply device 10 is in the first state.

In S13, a pairing permission signal is transmitted to the communication device 15. That is, the control unit 13 permits the communication device 15 to shift to the pairing mode, and ends the operation.

Next, the pairing control process executed by the control unit 22 of the network device 20 will be described with reference to FIG.

First, in S21, it is determined whether or not the second pairing command signal is received from the setting device 27. That is, the control unit 22 determines whether or not the receiving unit 21a has received the second pairing command signal.

Then, "YES" in S21, that is, when the control unit 22 determines that the second pairing command signal has been received, the storage unit 23 stores the second pairing command signal and proceeds to S22. On the other hand, if it is determined in S21 that "NO", that is, the control unit 22 has not received the second pairing command signal, the end is set.

In S22, the pairing mode is entered. That is, the control unit 22 shifts to a state of accepting the identification information of the communication device 15 in order to perform pairing with the communication device 15. The pairing mode is continued for a predetermined time (for example, 3 to 10 minutes). The control unit 22 transmits the identification information of the network device 20 toward the communication device 15 during the pairing mode.

In the next S23, it is determined whether or not the identification information of the communication device 15 has been received. That is, the control unit 22 determines whether or not the communication device 15 has received the transmitted identification information of the communication device 15 by shifting to the pairing mode.

Then, if "YES" in S23, that is, the control unit 22 determines that the identification information of the communication device 15 has been received, the process proceeds to S24. On the other hand, if "NO" in S23, that is, the control unit 22 determines that the identification information of the communication device 15 has not been received, the identification information of the communication device 15 is monitored for the predetermined time (for example, 3 to 10 minutes). When this predetermined time has elapsed, the pairing mode is canceled and the end is set.

In the next S24, the identification information of the communication device 15 is stored. That is, the control unit 22 stores the identification information of the communication device 15 in the storage unit 23 and serves as an end.

In the toilet room TR shown in FIGS. 6 to 8, the toilet room TR1 for men and the toilet room TR2 for women are adjacent to each other. The toilet room TR1 is provided with a water-related device 10 such as a warm water washing toilet seat 10a to 10d, a urinal 10e to 10i, an automatic faucet 10j, 10k, and a hand drying device 10m. Further, the toilet room TR2 is provided with water-related equipment 10 such as a warm water washing toilet seat 10n, 10p to 10t, an automatic faucet 10u, 10v, and a hand drying device 10w.

The water supply device 10 is not limited to this, and other devices such as an auto soap dispenser and an electric water heater (not shown) may be provided. The toilet room TR1 is provided with the network device 20a for the toilet room TR1, and the toilet room TR2 is provided with the network device 20b for the toilet room TR2.

Here, as shown in FIG. 9, the warm water washing toilet seat 10a is provided above the toilet bowl 100. The device body 11 of the warm water washing toilet seat 10a includes a toilet seat 11a, a washing nozzle 11b that discharges washing water to a local part of the user's body (such as "Oshiri") sitting on the toilet seat 11a, and a lid portion 11c that covers the upper part of the toilet seat 11a. It has a human body detection unit 12 for detecting a human body, a control unit 13 for controlling the operation of the warm water washing toilet seat 10a, and a storage unit 14 for storing a control program executed by the control unit 13.

In this example, when the seating sensor 12a of the warm water washing toilet seat 10a detects the seating on the toilet seat 11a, the warm water washing toilet seat 10a is set to be in the second state. When the human body detection sensor 12b that detects the human body in front of the warm water washing toilet seat 10a detects the human body, the warm water washing toilet seat 10a may be set to be in the second state.

As shown in FIG. 6, the administrator can shift the communication device 15 to the pairing mode by operating the command device 25 while sitting on the toilet seat 11a of the warm water washing toilet seat 10a. In FIG. 6, the seated state of the toilet seat 11a is shown by diagonal lines for convenience of explanation.

When the administrator operates the command device 25 without sitting on the toilet seat 11a, the warm water washing toilet seat 10a is in the first state, so that the communication device 15 cannot be shifted to the pairing mode. That is, when the command device 25 is operated to shift the warm water washing toilet seat 10a to the pairing mode, even if the adjacent warm water washing toilet seat 10b receives the pairing command signal, the warm water washing toilet seat 10b is in the first state. Because there is, it does not shift to pairing mode. Similarly for the urinals 10e to 10i, the automatic faucets 10j, 10k, the hand drying device 10m, and the other water-related devices 10 provided in the toilet room TR2, even if the pairing command signal is received, each water-related device Since 10 is in the first state, each communication device 15 does not shift to the pairing mode.

Next, as shown in FIG. 7, the administrator operates the setting device 27. In this case, since both the network device 20a and the network device 20b are provided within the communication range of the setting device 27, the setting device 27 has a selection screen for which network device 20 is to be shifted to the pairing mode. Is displayed. Then, when the administrator selects the network device 20a, the setting device 27 transmits the second pairing command signal to the network device 20a. Upon receiving the second pairing command signal, the network device 20a shifts to the pairing mode.

As shown in FIG. 8, when both the communication device 15 and the network device 20a of the warm water washing toilet seat 10a shift to the pairing mode, the communication device 15 and the network device 20a are automatically paired. In this case, the setting device 27 displays the identification information of the paired communication device 15. If there is a display of erroneous pairing, the pairing between the erroneously paired communication device 15 and the network device 20 can be canceled by the setting device 27. After the pairing is performed, the communication device 15 of the warm water washing toilet seat 10a and the network device 20a store each other's identification information, and data communication can be performed according to the second communication standard.

In the other water supply device 10, the communication device 15 and the network device 20 can be paired by the same work procedure. The communication device 15 can continue the pairing mode for a predetermined time. Therefore, by shifting each communication device 15 of the plurality of water-related devices 10 to the pairing mode and shifting the network device 20 to the pairing mode within the predetermined time, each communication device of the plurality of water-related devices 10 is shifted. The 15 and the network device 20 can be paired together. As a result, it is possible to suppress erroneous pairing and reduce the work time of the pairing work, so that the work efficiency of the pairing work can be improved.

Thus, the communication system 1 of the water-related device according to the present embodiment includes a plurality of water-related devices 10 having a communication device 15, a network device 20 connected to the external device 40 via the network 30, a communication device 15, and a network. It includes a command device 25 for transmitting a pairing command signal for pairing with the device 20 to the communication device 15.

Then, the communication device 15 can receive both a pairing command signal according to the first communication standard for unidirectional communication and a signal according to the second communication standard for bidirectional communication with the network device 20 from the command device 25. The water supply device 10 has a first state in which pairing is not permitted and a second state in which the water supply device 10 is switched from the first state to allow pairing by the switching operation to the water supply device 10. When the pairing command signal transmitted from the command device 25 is received, the command device 15 does not shift to the pairing mode for pairing with the network device 20 when the water supply device 10 is in the first state, and the command device 15 does not shift to the pairing mode. When the pairing command signal transmitted from 25 is received, when the water supply device 10 is in the second state, the mode shifts to the pairing mode for pairing with the network device 20.

As a result, the communication device 15 can be efficiently shifted to the pairing mode by using the communication device 15 capable of receiving signals according to both the first communication standard and the second communication standard. Further, even if the communication device 15 receives the pairing command signal from the command device 25, the communication device 15 does not shift to the pairing mode unless the water supply device 10 is in the second state, so that the network device 20 and the communication device 15 are erroneously used. Pairing can be suppressed. That is, even if another water-related device 10 that does not want to be paired receives the pairing command signal, it does not shift to the pairing mode, so that erroneous pairing can be suppressed. Therefore, it is possible to reduce the work load of the pairing work between the plurality of water-related devices 10 and the network device 20.

Further, the water supply device 10 includes a human body detecting unit 12 for detecting the human body, and the second state is a state in which the human body detecting unit 12 detects the human body. As a result, the communication device 15 can shift to the pairing mode by using the human body detection unit 12 of the water supply device 10. Therefore, it is possible to suppress erroneous pairing and to construct a network easily and quickly.

Next, with reference to FIG. 9, the communication system of the water supply device according to the second embodiment of the present invention will be described. The feature of the second embodiment is that the operation device 70 for operating the water supply device 10 has the function of the command device instead of the dedicated command device 25 for pairing.

The operating device 70 has, for example, a switch or a button, and is for operating each function such as toilet bowl cleaning and local cleaning. The operating device 70 also serves as a remote controller for transmitting a pairing command signal to the communication device 15.

The pairing command signal is not transmitted, for example, in normal use of the operating device 70. For example, the operating device 70 may have a switch for a pairing command inside the lid portion that can be opened only by the administrator. Further, the operating device 70 performs a special operation different from the normal use of the switch, such as operating the toilet bowl cleaning switch a plurality of times in a predetermined time or operating the plurality of switches in an arbitrary order. Therefore, the pairing command signal may be transmitted.

Also in the second embodiment configured in this way, the work load of the pairing work between the plurality of water supply devices 10 and the network device 20 can be reduced as in the first embodiment. In the second embodiment, the network can be constructed by using the operating device 70 that operates the water supply device 10. Therefore, since it is not necessary to prepare a dedicated command device 25 for network construction, the administrator does not need to carry the command device 25, and the network can be efficiently constructed.
