DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, wiring systems and communication systems according to embodiments will be described with reference to the drawings. However, the following embodiment is merely one of various embodiments of the present disclosure. The following embodiment can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. Furthermore, each figure described in the following embodiment is a schematic diagram, and the ratios of the sizes and thicknesses of the components in the figures do not necessarily reflect the actual dimensional ratios.

[0012] (1) Overview The wiring system 1 (wiring device) of this embodiment is installed in a facility 7. The facility 7 is, for example, a residential facility such as a detached house or an apartment building, or a non-residential facility such as an office, a store, an underground shopping mall, a hotel, a station, an airport, a school, a factory, a library, an art gallery, a museum, a hospital, or a nursing home. In this embodiment, an example will be described in which the wiring system 1 is used in a detached house as the facility 7. As shown in FIGS. 1 and 2 , the wiring system 1 of this embodiment is an outlet 10.

[0013] As shown in Fig. 1, the wiring system 1 includes a power supply side connector 17 and a load side connector 18. The power supply side connector 17 is connected to an external power source 90 such as a commercial power source or a distributed power source. The load side connector 18 is connected to an external electrical device. The load side connector 18 receives power from the power source 90 via the power supply side connector 17 and outputs the power to the electrical device.

[0014] As shown in FIG. 1, the wiring system 1 of this embodiment further includes a microphone 11, a command recognition unit 121, and a communication unit 13.

[0015] The microphone 11 outputs an electrical signal based on the input sound. The command recognition unit 121 performs voice recognition to recognize the voice contained in the sound based on the electrical signal output from the microphone 11, and recognizes the command indicated by the recognized voice. The communication unit 13 transmits an instruction signal S1 including the command recognized by the command recognition unit 121 to the external target device 2.

[0016] As described above, in this embodiment, the wiring system 1 installed in the facility 7 can transmit the instruction signal S1 to the target device 2 to control the target device 2. Therefore, according to this embodiment, it is possible to improve convenience for the user.

[0017] (2) Details Hereinafter, a wiring system 1 of this embodiment and a communication system 100 including the same will be described with reference to the drawings. As described above, the wiring system 1 of this embodiment is an outlet. Therefore, hereinafter, the wiring system 1 may be referred to as an "outlet 10."

[0018] (2.1) Communication Systems FIG. 1 is a block diagram of a communication system 100 including an outlet 10. FIG. 2 is a diagram illustrating an example of a facility 7 to which the communication system 100 is applied. As illustrated in FIGS. 1 and 2 , the communication system 100 includes an outlet 10 (wiring system 1), a target device 2, a communication device 3, and an electrical device 80 to be controlled. The electrical device 80 to be controlled here refers to the electrical device 80 that is controlled by the outlet 10. The communication device 3 and the electrical device 80 do not necessarily have to be included as components of the communication system 100. The facility 7 may also include other elements, such as an outlet that does not include a command recognition unit 121 or the like, or an electrical device other than the electrical device 80 to be controlled. In the example of FIG. 2 , the communication system 100 includes three outlets 10 (wiring system 1), but the present invention is not limited to this and the communication system 100 may include one or more outlets 10.

[0019] As shown in Figures 1 and 2, the outlet 10 (wiring system 1) includes a microphone 11, a processing unit 12, a communication unit 13, a memory unit 14, a power supply unit 15, a power supply side connector 17, a load side connector 18, and a housing 19.

[0020] The microphone 11 outputs an electrical signal based on the input sound. Specifically, the microphone 11 collects sounds such as human speech, converts them into electrical signals, and outputs the converted electrical signals to the processing unit 12. In this embodiment, the microphone 11 has an analog-to-digital conversion unit (A / D conversion unit) and converts analog electrical signals into digital electrical signals for output.

[0021] The processing unit 12 is configured, for example, by a microcomputer mainly composed of a processor and a memory. In other words, the processing unit 12 is realized by a computer system having a processor and a memory. The processor executes an appropriate program, causing the computer system to function as the processing unit 12. The program may be pre-recorded in the memory, or may be provided via a telecommunications line such as the Internet, or recorded on a non-transitory recording medium such as a memory card. The processing unit 12 performs overall control of the outlet 10. Details of the processing unit 12 will be described later.

[0022] The communication unit 13 includes a first communication unit 131 and a second communication unit 132.

[0023] The first communication unit 131 communicates with the target device 2. The first communication unit 131 includes, for example, a communication interface that complies with the standard for low-power radio that does not require a radio station license. For this type of low-power radio, specifications such as the frequency band or antenna power to be used are defined in each country depending on the application. In Japan, low-power radio (specified low-power radio) that uses radio waves in the 920 MHz band or 420 MHz band is defined. That is, the first communication unit 131 communicates with the target device 2 in accordance with the first communication protocol (communication protocol for specified low-power radio).

[0024] The second communication unit 132 communicates with the communication device 3. The second communication unit 132 includes a communication interface that complies with the Bluetooth (registered trademark) standard, for example. That is, the second communication unit 132 communicates with the communication device 3 in accordance with a second communication protocol (Bluetooth communication protocol).

[0025] In this way, the first communication protocol (the communication protocol that the communication unit 13 follows when communicating with the target device 2) and the second communication protocol (the communication protocol that the communication unit 13 follows when communicating with the communication device 3) are different from each other.

[0026] The storage unit 14 includes a rewritable nonvolatile memory such as an EEPROM (Electrically Erasable Programmable Read-Only Memory). The storage unit 14 stores various information used in the processing of the processing unit 12. The storage unit 14 may also serve as the memory of the processing unit 12.

[0027] The power supply connector 17 includes, for example, a pair of power supply connection terminals. Each power supply connection terminal is, for example, a quick-connect terminal. The pair of power supply connection terminals is connected to a pair of electric wires of a power line connected to the power supply 90 (via the distribution board 70 in the example of FIG. 2).

[0028] The load-side connector 18 includes, for example, a pair of load-side connection terminals. Each load-side connection terminal is, for example, a blade receptacle. The pair of load-side connection terminals is connected to a pair of blades of a plug connected to an electrical device 80, respectively.

[0029] The power supply unit 15 generates operating power for each component within the outlet 10, such as the processing unit 12. The power supply unit 15 is connected to an electric circuit connecting the power supply connector 17 and the load connector 18. The power supply unit 15 includes, for example, an AC / DC converter. The AC / DC converter converts AC power received from the power supply 90 via the power supply connector 17 into DC power, and supplies the obtained DC power to the processing unit 12 and the like as operating power.

[0030] The housing 19 accommodates the microphone 11, the command recognition unit 121, the communication unit 13, the power connector 17, and the load connector 18. As shown in FIG. 2 , the housing 19 is installed (fixed) to a building such as a wall of the facility 7. As another example, the outlet 10 is assumed to be a recessed type in which the rear of the housing 19 is embedded in a construction hole in the building. In this case, the outlet 10 is attached to the building (here, a wall) using a mounting member such as a recessed switch box. For example, a construction hole is formed in the building, and the housing 19 is attached to a mounting member such as a switch box located on the rear side (behind the wall) of the building through the construction hole. However, the housing 19 may be fixed to a building other than a wall, such as a ceiling or floor, or to fixtures (including fittings) such as a desk, shelf, or counter. The outlet 10 may also be an exposed type in which the housing 19 is directly attached to the surface of the building 71, or a stationary type such as a power strip.

[0031] 1 and 2, in the communication system 100 of this embodiment, the target device 2 is a switch (wall switch). Therefore, hereinafter, the target device 2 may be referred to as a "switch 20." The switch 20 (directly or indirectly) controls the operation of the electrical device 80 that is the control target.

[0032] Here, switch 20 is a lighting switch for controlling lighting fixtures. Switch 20 is connected to lighting fixtures 81 via a power line. In this embodiment, electrical devices 80 to be controlled include lighting fixtures 81 connected to switch 20 (target devices 2) via a power line.

[0033] 1 and 2, switch 20 includes touch panel 21, communication unit 22, processing unit 23, memory unit 24, phase control unit 25, power supply unit 26, and housing 27 that houses or holds these components. As shown in Fig. 2, switch 20 (housing 27) is installed (fixed) to a building such as a wall of facility 7.

[0034] The touch panel 21 is disposed on the front surface of the body 27. The touch panel 21 functions as a display unit 211. The display unit 211 has, for example, an electronic paper screen capable of displaying two colors, black and white. Electronic paper is a self-holding display. The touch panel 21 is configured using a known touch panel such as a resistive film type, a capacitive type, or an electromagnetic induction type, and allows a user to perform a touch operation (tap) using a finger or a pen. In other words, the touch panel 21 also functions as an operation unit 212 that accepts operations by the user.

[0035] Display unit 211 of touch panel 21 displays, for example, an image (icon) indicating electrical appliance 80 to be controlled. In addition to lighting fixture 81 described above, electrical appliance 80 to be controlled may include electrical appliances 82 other than lighting fixture 81, such as air conditioners, television sets, and power curtains. With the image of electrical appliance 80 to be controlled displayed on display unit 211, operation unit 212 accepts appropriate touch operations from the user.

[0036] The communication unit 22 communicates with the outlet 10 (more specifically, the first communication unit 131). In this example, the communication unit 22 is provided with a communication interface that complies with the standard for low-power radio that does not require a radio station license. The communication unit 22 communicates with the outlet 10 in accordance with the first communication protocol (a communication protocol for specified low-power radio). By communicating with the outlet 10, the communication unit 22 receives an instruction signal S1 from the communication unit 13.

[0037] Furthermore, the communication unit 22 communicates with the electrical appliance 80 to be controlled (electrical appliance 82 other than the lighting fixture 81). Here, the communication unit 22 communicates with an external control device, and the control device communicates with the electrical appliance 82, whereby the communication unit 22 communicates indirectly with the electrical appliance 82. The communication protocol that the communication unit 22 follows when communicating with the control device may be a first communication protocol (a specified low-power radio communication protocol) or another communication protocol (for example, a Bluetooth communication protocol). The control device communicates with the electrical appliance 82 according to an appropriate communication protocol (for example, an infrared communication protocol). The communication unit 22 communicates with the electrical appliance 82 to transmit an instruction signal S1 to the electrical appliance 82 (control device). Specifically, the communication unit 22 transfers the instruction signal S1 received from the outlet 10 to the electrical appliance 82. Note that the communication unit 22 may have a communication interface that allows direct communication with the electrical appliance 82 and communicate directly with the electrical appliance 82 without going through the control device.

[0038] The processing unit 23 is configured, for example, by a microcomputer mainly composed of a processor and a memory. In other words, the processing unit 23 is realized by a computer system having a processor and a memory. The processor executes an appropriate program, causing the computer system to function as the processing unit 23. The program may be pre-recorded in the memory, or may be provided via a telecommunications line such as the Internet, or recorded on a non-transitory recording medium such as a memory card. The processing unit 23 performs overall control of the switch 20.

[0039] The processing unit 23 controls the operation of the power supply unit 26. The power supply unit 26 generates operating power for the touch panel 21, the communication unit 22, the phase control unit 25, etc. to operate, and supplies the generated operating power to them. The power supply unit 26 has, for example, a rectifier that rectifies an input voltage from a power line connected to the power supply 90, and a switching power supply or a linear power supply that converts the output voltage of the rectifier into a DC voltage.

[0040] Processing unit 23 controls the operation of phase control unit 25. Phase control unit 25 includes semiconductor switching elements such as triacs, thyristors, field effect transistors (FETs), and bipolar transistors. Phase control unit 25 is connected in series with power supply 90 and lighting device 81. Processing unit 23 has a function of adjusting the period (conduction angle) during which power is supplied from power supply 90 to lighting device 81 within one AC power cycle by controlling the on-period of the semiconductor switching elements of phase control unit 25. By adjusting the conduction angle, processing unit 23 can switch lighting device 81 on and off and adjust the brightness and color of lighting device 81. In this way, switch 20 (target device 2) directly controls the operation of lighting device 81 as the electrical device 80 to be controlled. When an image of lighting device 81 is displayed on display unit 211 and processing unit 23 receives an appropriate touch operation from the user on operation unit 212, processing unit 23 appropriately changes the lighting state of lighting device 81 (switching between on and off, dimming, adjusting color, etc.).

[0041] Furthermore, processing unit 23 controls the operation of electric appliance 82 other than lighting fixture 81 by transmitting instruction signal S1 from communication unit 22 via the control device to this electric appliance 82. When processing unit 23 receives an appropriate touch operation from the user on operation unit 212 while an image of electric appliance 82 is displayed on display unit 211, processing unit 23 transmits instruction signal S1 including instruction content corresponding to the received touch operation to electric appliance 82 via the control device. In this way, switch 20 (target device 2) indirectly controls the operation of electric appliance 82 as the electric appliance 80 to be controlled.

[0042] Furthermore, when the processing unit 23 receives an instruction signal S1 including a command from the outlet 10, it controls the operation of the electrical appliance 80 (lighting fixture 81 and electrical appliance 82) to be controlled in accordance with the command.

[0043] The storage unit 24 includes a rewritable nonvolatile memory such as an EEPROM (Electrically Erasable Programmable Read-Only Memory) or a flash memory. The storage unit 24 stores various information used in the processing of the processing unit 23. The storage unit 24 may also serve as the memory of the processing unit 23.

[0044] The housing 27 houses the touch panel 21, the communication unit 22, the processing unit 23, the memory unit 24, the phase control unit 25, and the power supply unit 26. As shown in FIG. 2 , the housing 27 is installed (fixed) to a structure such as a wall of the facility 7. In particular, the housing 27 may be installed above the housing 19 of the outlet 10 in the facility 7. "Above" here does not necessarily mean directly above the housing 19 in the strict sense, but may include a margin of error within an acceptable range. Thus, the housing 19 of the outlet 10 (wiring system 1) is located below the switch 20 (target device 2) in the facility 7. This arrangement can prevent an increase in the wiring length between the outlet 10 and the switch 20 and simplify the wiring work performed by an installer. The housing 27 and the housing 19 may be installed on the same wall in the facility 7.

[0045] Here, the communication device 3 is a portable information terminal 30 carried by a user. The information terminal 30 is, for example, a smartphone. However, the information terminal 30 is not limited to a smartphone, and may be a tablet terminal, a personal computer (desktop computer, laptop computer, etc.), etc.

[0046] As shown in FIG. 1, the information terminal 30 includes an operation unit 31, a display unit 32, a communication unit 33, and a processing unit .

[0047] The operation unit 31 is used to input information to the information terminal 30. The operation unit 31 includes an input device for operating the information terminal 30. The input device has, for example, a touchpad and / or one or more buttons. The input device is not limited to a touchpad, and may be a keyboard, a pointing device, a mechanical switch, or the like. The input device may include a voice input device. The operation unit 31 may include multiple input devices.

[0048] The display unit 32 is used to output information from the information terminal 30. The display unit 32 includes an image display device for displaying information. The image display device is, for example, a thin display device such as a liquid crystal display or an organic EL display. Note that the touchpad of the operation unit 31 and the image display device of the display unit 32 may form a touch panel. The information terminal 30 may also include an audio output device that outputs information as sound.

[0049] The communication unit 33 communicates with the communication unit 13 (more specifically, the second communication unit 132) of the outlet 10. The communication unit 33 has a communication interface that complies with the Bluetooth standard, for example. That is, the communication unit 33 communicates with the outlet 10 in accordance with the second communication protocol (the Bluetooth communication protocol).

[0050] The processing unit 34 is configured, for example, by a microcomputer mainly composed of a processor and a memory. In other words, the processing unit 34 is realized by a computer system having a processor and a memory. The processor executes an appropriate program, causing the computer system to function as the processing unit 34. The program may be pre-recorded in the memory, or may be provided via a telecommunications line such as the Internet, or recorded on a non-transitory recording medium such as a memory card.

[0051] The processing unit 34 is configured to perform overall control of the information terminal 30, that is, to control the operation unit 31, the display unit 32, and the communication unit 33. The functions of the processing unit 34 are realized by one or more processors of the processing unit 34 executing a program.

[0052] The processing unit 34 has a function of causing the outlet 10 to perform a process (setting process) to register setting information in the outlet 10. The setting process will be described later.

[0053] Electrical equipment 80 is placed (installed) at an appropriate location within facility 7. Electrical equipment 80 includes lighting fixtures 81 that are connected to switch 20 and whose operating state (lighting state) is controlled by switch 20. Electrical equipment 80 also includes electrical equipment 82 other than lighting fixtures 81. Examples of electrical equipment 82 may include an air conditioner, a television set, and electric curtains. Electrical equipment 82 includes a communication unit that communicates with switch 20 via a control device.

[0054] (2.2) Processing section of wiring system The function of the processing unit 12 of the outlet 10 (wiring system 1) will be described in more detail below.

[0055] 1, the processing unit 12 includes a voice recognition unit 120 and a setting processing unit 124. Note that the voice recognition unit 120 and the setting processing unit 124 are not tangible components but represent functions realized by the processing unit 12.

[0056] The speech recognition unit 120 performs speech recognition based on the electrical signal output from the microphone 11. "Speech recognition" here refers not only to the process of converting human speech into text but also to natural language processing such as semantic analysis and contextual analysis. Specifically, the speech recognition unit 120 compares the electrical signal with multiple speech models pre-stored in the storage unit 14. If a speech model matching the electrical signal is found, the speech recognition unit 120 recognizes that the sound input to the microphone 11 contains an instruction speech. The instruction speech here refers to a speech that indicates a command instructing the electrical device 80 to execute a specific function. Hereinafter, a "command instructing the electrical device 80 to execute a specific function" may be simply referred to as a "command." Furthermore, the speech models stored in the storage unit 14 may be referred to as "command candidates." Furthermore, in the present disclosure, "match" does not necessarily mean a perfect match between the comparison targets, but also includes a similarity at a predetermined level or higher.

[0057] A "command (command candidate)" in this embodiment includes a first layer indicating the electrical appliance 80 to be controlled, and a second layer indicating the content of the command (control content) for the electrical appliance 80. The first layer may include the type of electrical appliance 80 and the installation location of the electrical appliance 80. In other words, the "command" may be a command that instructs the electrical appliance 80 indicated in the first layer to execute the control content indicated in the second layer. Table 1 below shows an example of a voice model (command candidate) stored in the storage unit 14.

[0058] [Table 1]

[0059] In the example of Table 1, "living room air conditioner," "living room lighting," "living room TV," and "living room curtains" in the first layer refer to the air conditioner, lighting fixtures, television set, and electric curtains, respectively, installed in the living room of facility 7. Similarly, "bedroom air conditioner," "bedroom lighting," "bedroom TV," and "bedroom curtains" in the first layer refer to the air conditioner, lighting fixtures, television set, and electric curtains, respectively, installed in the bedroom of facility 7.

[0060] In the second layer, "cool," "heat," "fan," "dehumidify," and "auto" associated with air conditioners indicate control content that instructs the air conditioner's operating mode to switch to "cool," "heat," "fan," "dehumidify," and "auto," respectively. "Turn off" associated with air conditioners indicates control content that instructs the air conditioner to stop operating. "Increase temperature" and "decrease temperature" associated with air conditioners in the second layer indicate control content that instructs the air conditioner to increase or decrease the set temperature, respectively. "Increase airflow" and "decrease airflow" associated with air conditioners in the second layer indicate control content that instructs the air conditioner to increase or decrease the set airflow, respectively. "Sleep mode" and "internal purification" associated with air conditioners in the second layer indicate control content that instructs the air conditioner's operating mode to switch to sleep mode and internal purification mode, respectively.

[0061] In the second layer, "Turn on" and "Turn off" associated with a lighting fixture indicate controls to turn the lighting fixture on and off, respectively. In the second layer, "Brighten up" and "Dim down" associated with a lighting fixture indicate controls to dim the lighting fixture (increase and decrease the dimming level), respectively. In the second layer, "Full on" associated with a lighting fixture indicates controls to dim the lighting fixture (increase the dimming level to 100%). In the second layer, "Warm color" and "White color" associated with a lighting fixture indicate controls to adjust the lighting fixture's color tone (change to a warm color tone or a cool color tone), respectively. In the second layer, "Night light" associated with a lighting fixture indicates controls to turn on the lighting fixture's night light.

[0062] In the second layer, "Turn on" and "Turn off" associated with a television set indicate controls to turn the television set on and off, respectively. In the second layer, "Channel up" and "Channel down" associated with a television set indicate controls to change the television set's channel selection, respectively. In the second layer, "Volume up" and "Volume down" associated with a television set indicate controls to increase and decrease the volume of the television set, respectively.

[0063] In the second layer, "open" and "close" associated with the electric curtain indicate control content to open or close the electric curtain. In the second layer, "stop" associated with the electric curtain indicates control content to stop the opening or closing of the electric curtain.

[0064] In the first layer, "collective control" and "all" refer to all of the controlled electrical appliances 80. In the second layer, "turn on" and "turn off" associated with multiple appliances refer to control content that instructs turning on or off the power of all of the controlled electrical appliances 80, respectively.

[0065] Furthermore, "sleep mode," "good morning mode," "go out mode," and "at home mode" in Table 1 are each command candidates for collectively instructing preset control contents for one or more electrical appliances 80 associated with the corresponding mode. For example, "sleep mode" is a command candidate for turning off the power to the living room lights, bedroom lights, living room TV, bedroom TV, and living room air conditioner, operating the bedroom air conditioner in sleep mode, and closing the living room curtains and bedroom curtains. There is no distinction between first and second layers for these command candidates, and one command candidate is configured by one voice model corresponding to a continuous character string.

[0066] For example, when a voice model included in the first layer and a voice model included in the second layer are consecutively recognized within a predetermined time in the sound input to the microphone 11, the voice recognition unit 120 recognizes that the sound input to the microphone 11 contains an instruction voice. The voice recognition unit 120 recognizes a command based on the instruction voice included in the sound input to the microphone 11.

[0067] As described above, the voice recognition unit 120 includes a command recognition unit 121. The command recognition unit 121 performs voice recognition to recognize the voice included in the sound input to the microphone 11 based on the electrical signal, and recognizes the command indicated by the recognized voice. The command recognition unit 121 recognizes the command indicated by the recognized voice based on a plurality of command candidates stored in the storage unit 14.

[0068] Note that the commands (command candidates) are not limited to those shown in Table 1, and may be changed / added / deleted as appropriate.

[0069] The voice recognition unit 120 of this embodiment further has a function of performing speaker recognition based on an electrical signal derived from a sound input to the microphone 11. Speaker recognition is a computer process for recognizing a speaker from a voice. Here, the voice recognition unit 120 recognizes the speaker of the voice using speaker identification technology. For example, information indicating features of the voices of one or more subjects is stored in the storage unit 14 as registered voice information. The voice recognition unit 120 recognizes the speaker by comparing the features of the voice input to the microphone 11 with the registered voice information (features of the voices of the subjects) stored in the storage unit 14. The voice recognition unit 120 particularly recognizes the speaker of a voice indicating a command voice among the sounds input to the microphone 11.

[0070] Thus, the voice recognition unit 120 includes a speaker recognition unit 122. The speaker recognition unit 122 recognizes the speaker of the voice indicating the command (instruction voice).

[0071] The processing unit 12 (voice recognition unit 120) also includes a determination unit 123. The determination unit 123 determines whether speaker voice information (voice feature values) relating to the voice of a speaker recognized by the speaker recognition unit 122 matches registered voice information relating to the voice of a pre-registered target person. That is, the determination unit 123 determines whether the speaker recognized by the speaker recognition unit 122 is registered as a target person. The processing of the determination unit 123 may be performed simultaneously in parallel with the processing of the speaker recognition unit 122 described above. The processing of the speaker recognition unit 122 and the processing of the determination unit 123 may also be performed simultaneously in parallel with the processing of the command recognition unit 121 described above.

[0072] The processing unit 12 causes the communication unit 13 (first communication unit 131) to transmit an instruction signal S1 including a command instructed by the instruction voice only when the judgment unit 123 judges that the speaker voice information matches the registered voice information. In other words, the communication unit 13 (first communication unit 131) transmits the instruction signal S1 when the speaker voice information matches the registered voice information.

[0073] In this way, the outlet 10 of this embodiment transmits an instruction signal S1 including a command only if the speaker of the instruction voice (voice indicating a command) is registered as a target person. This reduces the possibility that an instruction signal S1 not intended by the target person will be transmitted to the switch 20, causing the electrical appliance 80 to malfunction. For example, this reduces the possibility that the electrical appliance 80 will malfunction due to everyday sounds such as voices emitted by a television receiver or artificial sounds emitted by electrical appliances.

[0074] The setting processing unit 124 performs setting processing to register setting information. The setting information includes various information used by the voice recognition unit 120. The setting processing unit 124 registers the setting information in response to a setting instruction signal S2 transmitted from the information terminal 30. The setting processing unit 124 stores the setting information in the storage unit 14.

[0075] The setting information may include, for example, information indicating whether each of the multiple command candidates is valid or invalid. The setting information may include, for example, information indicating a newly added command candidate. The setting information may include, for example, information indicating the changed control content when changing the control content (second layer) of a command candidate. The setting information may include, for example, information indicating the command candidate to be deleted when deleting a command candidate. In this way, the communication unit 13 (second communication unit 132) receives setting information related to the setting of at least one command candidate from the information terminal 30 (communication device 3).

[0076] Furthermore, the setting processing unit 124 of this embodiment includes a registration processing unit 125. The registration processing unit 125 registers registration voice information. The registration voice information is information related to the voice of the subject that is stored (registered) in the storage unit 14, and specifically, is information indicating the features of the subject's voice. For example, the registration voice information is linked to the subject's identification information and stored (registered) in the storage unit 14 for each subject. The subject may include a resident of a detached house that serves as the facility 7. The subject may also include the resident's relatives, friends, associates, etc.

[0077] In the outlet 10 of this embodiment, the registration processing unit 125 performs the registration process of the registration voice information in response to the registration instruction signal S20 transmitted from the information terminal 30.

[0078] More specifically, when the information terminal 30 receives an appropriate input operation from the user via the operation unit 31, it transmits a registration instruction signal S20 to the outlet 10. The registration instruction signal S20 may include information indicating the person to be registered (identification information of the person) and an instruction to the outlet 10 to start a process of acquiring voice (an electrical signal indicating voice).

[0079] When the outlet 10 (processing unit 12) receives the registration instruction signal S20 via the communication unit 13 (second communication unit 132), it starts the process of acquiring voice via the microphone 11. The outlet 10 (processing unit 12) executes the process of acquiring voice via the microphone 11 for a predetermined period of time after starting the acquisition process. The processing unit 12 extracts features of the voice input to the microphone 11 based on an electrical signal based on the acquired voice, and associates the extracted features with the identification information of the subject and registers them as registration voice information (stores them in the memory unit 14).

[0080] As described above, in the outlet 10 of this embodiment, the registration processing unit 125 starts acquiring information about the target person's voice in response to a registration instruction signal S20 transmitted from the information terminal 30 (communication device 3). This makes it possible to simplify the structure of the outlet 10 compared to when acquisition of information about the target person's voice is started in response to, for example, pressing a switch or the like provided on the outlet 10.

[0081] Furthermore, in the outlet 10 of this embodiment, the registration processing unit 125 acquires information about the target person's voice based on sound input to the microphone 11 of the outlet 10 (wiring system 1), and registers registration voice information based on the acquired information about the target person's voice. In other words, the registration processing unit 125 acquires information about the target person's voice based on sound acquired by the microphone 11, which acquires sound used for voice recognition by the voice recognition unit 120. This makes it possible to improve the accuracy of voice recognition by the voice recognition unit 120 compared to acquiring information about the target person's voice based on sound input other than the microphone 11, for example, sound input to a voice input unit of the information terminal 30.

[0082] (2.3) Operation Hereinafter, the operation of the communication system 100 when recognizing a voice uttered by a user and transmitting an instruction signal S1 will be described with reference to FIG.

[0083] First, when sound is input to the microphone 11, the microphone 11 outputs an electrical signal based on the input sound. Furthermore, the processing unit 12 performs voice recognition processing based on the electrical signal from the microphone 11. Specifically, the processing unit 12 compares the electrical signal with a voice model (a voice model included in the first layer) and determines whether or not a voice model that matches the electrical signal exists. If the result of the voice recognition is that the sound input to the microphone 11 does not contain any voice (ST1: No) or there is no voice model that matches the electrical signal (ST2: No), the processing unit 12 returns to step ST1 and waits for input of an electrical signal from the microphone 11.

[0084] On the other hand, if the result of the voice recognition is that the sound input to the microphone 11 contains voice (ST1: Yes) and the electrical signal matches one of the voice models included in the first layer (ST2: Yes), the processing unit 12 determines whether the speaker of the voice is a target person registered in the registered voice information.

[0085] If the speaker is not the target person (ST3: No), the processing unit 12 ends the processing. If the speaker is the target person (ST3: Yes), the processing unit 12 determines whether the subsequently received electrical signal matches a voice model (any of the voice models included in the second layer). If the electrical signal matches any of the voice models included in the second layer (ST4: Yes), the processing unit 12 determines the content of the command indicated by the voice (ST6) and outputs an instruction signal S1 including the command (ST7). On the other hand, if a predetermined time has passed since the detection of voice matching the voice model of the first layer, and voice matching the voice model of the second layer has not been detected (ST5: Yes), the processing unit 12 ends the processing.

[0086] Next, the operation of communication system 100 when performing registration processing will be described with reference to FIG.

[0087] First, upon receiving an appropriate operation input from the user via operation unit 31 (ST11), information terminal 30 transmits a registration instruction signal S20 to outlet 10 to cause outlet 10 to start the registration process (ST12). In addition, information terminal 30 displays on display unit 32 an appropriate message (for example, "Please say XX in front of the outlet") encouraging the user to speak into microphone 11 of outlet 10.

[0088] The outlet 10 executes a voice acquisition process using the microphone 11 for a predetermined period of time after receiving the registration instruction signal S20 (ST13).

[0089] When the voice is acquired, the processing unit 12 of the outlet 10 extracts features of the acquired voice (ST14), associates the extracted features with the identification information included in the registration instruction signal S20, and registers them as registered voice information (ST15).

[0090] As described above, in this embodiment, the wiring system 1 (outlet 10) equipped with the load-side connector 18 and installed in the facility 7 can transmit an instruction signal S1 to the target device 2 (switch 20) to control the target device 2. Therefore, according to this embodiment, it is possible to improve user convenience.

[0091] Furthermore, in this embodiment, the wiring system 1 (outlet 10) equipped with the voice recognition unit 120 is installed in a building of the facility 7, so that the space within the facility 7 can be used effectively.
