Modes for Carrying Out the Invention

[0010] (1) Overview Hereinafter, the overview of the wiring device 1 and the wiring device system 100 according to the embodiment will be described with reference to FIG. 1. In FIG. 1, the broken line represents the flow of signals. In the present embodiment, the wiring device 1 has the function of an outlet to which the plug of the electrical device A1 is connected to supply power to the electrical device A1. Here, it is assumed that the wiring device 1 is for AC 100V and is a two-outlet type outlet that can connect two plugs simultaneously. Further, in the present embodiment, it is assumed that the wiring device 1 is an indoor outlet attached to the inner wall of a building. The building in which the wiring device 1 is installed is, for example, a detached house, an apartment house, a factory, an office, a store, or a nursing facility.

[0011] The wiring device 1 of this embodiment includes a processing unit 14, a connection unit 11, a detection unit 12, and a communication unit 13. The connection unit 11 can be electrically connected to the electrical device A1. In this embodiment, when the plug of the electrical device A1 is connected to the connection unit 11 of the wiring device 1, power can be supplied from the wiring device 1 to the electrical device A1. And in this embodiment, the wiring device 1 is used for supplying power to various electrical devices A1 such as lighting fixtures, air conditioning equipment, and refrigerators.

[0012] The detection unit 12 detects the state of the environment where the connection unit 11 is placed. For example, if the detection unit 12 is a temperature sensor, the detection unit 12 detects the temperature of the connection unit 11 as the state of the environment where the connection unit 11 is placed. Also, for example, if the detection unit 12 is a current sensor, the detection unit 12 detects the current flowing through the connection unit 11 as the state of the environment where the connection unit 11 is placed. The communication unit 13 can communicate with an external device 2 (reception device 3) different from the electrical device A1. And the processing unit 14 has a communication function of controlling the communication unit 13 to transmit a detection signal including the detection result of the detection unit 12 to the external device 2.

[0013] As described above, since the wiring device 1 of this embodiment has a communication function, not only can it detect the state of its own placed environment with the detection unit 12, but it can also transmit the detection result of the detection unit 12 to the external device 2. Therefore, for example, the administrator of the wiring device 1, such as the resident of the building where the wiring device 1 is installed, can obtain the detection result of the detection unit 12 through the external device 2, and grasp the state of the environment where the wiring device 1 is placed without directly examining the wiring device 1. That is, in this embodiment, there is an advantage that it is easy for the administrator of the wiring device 1 to grasp the state of the wiring device 1.

[0014] (2) Details Hereinafter, the wiring device 1 and the wiring device system 100 according to this embodiment will be described in detail with reference to FIG. 1. The wiring device system 100 of this embodiment includes a wiring device 1, a receiving device 3 as an external device 2, and a voice interface 5, a mobile terminal 7, and a server 8 as output devices 4. In addition to the connection part 11, the detection part 12, the communication part 13, and the processing part 14 already described, the wiring device 1 includes a cutoff part 15. In this embodiment, the connection part 11, the detection part 12, the communication part 13, the processing part 14, and the cutoff part 15 are all housed in the housing of the wiring device 1.

[0015] The connection part 11 is, for example, a blade receiving member to which a plug of an electric device A1 is connected. The connection part 11 is electrically connected to a power source B1 such as a commercial power source via an electric wire. Therefore, by connecting the plug of the electric device A1 to the connection part 11, the electric device A1 is electrically connected to the power source B1 via the connection part 11. Then, the power source B1 supplies power to the electric device A1 connected to the connection part 11.

[0016] The detection part 12 is configured to detect an abnormality related to the connection part 11 as the state of the environment where the connection part 11 is placed. In this embodiment, the detection part 12 has a temperature sensor that detects the temperature inside the housing of the wiring device 1. For example, when the contact resistance of the connection part 11 increases due to mechanical abnormalities such as plugging and unplugging more times than the assumed number of uses, or the attachment of foreign substances such as dust to the connection part 11, the heat generation amount at the connection part 11 increases, causing the temperature inside the housing of the wiring device 1 to rise. The detection part 12 can detect this temperature rise with the temperature sensor, and detect electrical abnormalities such as a decrease in the lifespan and insulation performance of the wiring device 1 as abnormalities related to the connection part 11. The temperature sensor is preferably installed at a site where the temperature is likely to rise when an abnormality occurs, such as near the connection part 11.

[0017] In this embodiment, the abnormality relates to a decrease in the insulation performance of the connection part 11. When the insulation performance of the connection part 11 decreases, the temperature inside the housing of the wiring device 1 is higher than normal. Therefore, by detecting the temperature that has risen more than normal by the detection part 12, it is possible to detect the abnormality at the stage when the insulation performance of the connection part 11 decreases.

[0018] The communication part 13 is a communication interface for communicating with the first communication part 31 (described later) of the receiving device 3. In this embodiment, the communication part 13 is a communication interface for low-power wireless communication that does not require a license for a wireless station. For this type of low-power wireless communication, specifications such as the frequency band to be used and the antenna power are defined in each country according to the application and the like. In Japan, low-power wireless communication (specific low-power wireless communication) that uses radio waves in the 920 MHz band or the 420 MHz band is defined.

[0019] The processing part 14 controls the detection part 12, the communication part 13, and the cutoff part 15. In this embodiment, the processing part 14 is composed of a microcomputer mainly composed of a processor and a memory. The same applies to the control part 34 of the receiving device 3 described later. That is, the processing part 14 (control part 34) is realized by a computer system having a processor and a memory. Then, when the processor executes an appropriate program, the computer system functions as the processing part 14 (control part 34). The program may be recorded in the memory in advance, or may be provided by being recorded on a recording medium such as a memory card through a telecommunication line such as the Internet.

[0020] The processing unit 14 is configured to acquire the detection result from the detection unit 12. In the present embodiment, the processing unit 14 acquires, as the detection result, the temperature inside the housing of the wiring device 1 detected by the detection unit 12. The processing unit 14 compares the detection result (temperature) of the detection unit 12 with a threshold temperature stored in advance. When the detection result exceeds the threshold temperature (including "becoming equal to or higher than the threshold"), the processing unit 14 determines that an abnormality related to the connection part 11 has been detected by the detection unit 12. Here, the processing unit 14 determines that an abnormality at the stage where the insulation performance of the connection part 11 deteriorates has been detected by the detection unit 12. In this case, the processing unit 14 generates a detection signal including the abnormality related to the connection part 11 as the detection result of the detection unit 12. Then, the processing unit 14 controls the communication unit 13 to transmit the generated detection signal to the receiving device 3 (external device 2). That is, when the detection unit 12 detects an abnormality, the processing unit 14 executes a communication function of controlling the communication unit 13 to transmit a detection signal to the receiving device 3 (external device 2).

[0021] Further, when the processing unit 14 determines that an abnormality related to the connection part 11 has been detected by the detection unit 12, it executes a cutoff function. The cutoff function is a function of cutting off the electric circuit L1 (described later) by controlling the cutoff part 15. In other words, the processing unit 14 has a cutoff function of controlling the cutoff part 15 to cut off the electric circuit L1 when a predetermined condition is satisfied. In the present embodiment, the predetermined condition includes detecting an abnormality related to the connection part 11 by the detection unit 12. Further, in the present embodiment, when the detection unit 12 detects an abnormality, the processing unit 14 executes the cutoff function. That is, in the present embodiment, only detecting an abnormality by the detection unit 12 is set as the predetermined condition. When the detection unit 12 detects an abnormality, the processing unit 14 may execute the cutoff function immediately or may execute the cutoff function after a certain period of time.

[0022] The cutoff part 15 is housed inside the housing of the wiring device 1. The cutoff part 15 is connected between the connection part 11 and the power source B1. The cutoff part 15 includes a contact for electrically connecting the connection part 11 and the power source B1, and a mover for opening and closing the contact. The cutoff part 15 operates the mover to open the contact under the control of the processing part 14. Thereby, the cutoff part 15 cuts off the circuit L1 between the connection part 11 and the power source B1. The circuit L1 is a power supply path from the power source B1 to the connection part 11 (or the electrical device A1 connected to the connection part 11).

[0023] Also, in the present embodiment, the cutoff part 15 has a switch for returning from the state where the circuit L1 is cut off to the original state. This switch is provided, for example, so as to be exposed from the housing of the wiring device 1. Therefore, in the state where the circuit L1 is cut off, for example, when a person operates the switch, the cutoff by the cutoff part 15 is released, and the circuit L1 returns to the original state.

[0024] In the present embodiment, the wiring device 1 further includes a power supply unit. The power supply unit is configured to receive power supply from the power source B1 via a circuit different from the circuit L1. Then, the power supply unit generates operating power upon receiving power supply from the power source B1, and supplies the generated operating power to the detection part 12, the communication part 13, and the processing part 14. For this reason, the detection part 12, the communication part 13, and the processing part 14 operate regardless of the opening and closing of the circuit L1.

[0025] The receiving device 3 is provided inside the building in which the wiring device 1 is installed. In the present embodiment, the receiving device 3 is an external device 2 and receives a detection signal from the wiring device 1. The receiving device 3 includes a first communication part 31, a second communication part 32, a third communication part 33, and a control part 34.

[0026] The first communication unit 31 is a communication interface for communicating with the communication unit 13 of the wiring device 1. In the present embodiment, the first communication unit 31 is a communication interface for low-power wireless communication that does not require a license for a wireless station. The second communication unit 32 is a communication interface for communicating with the mobile terminal 7 or the server 8 via a network N1 such as the router 6 or the Internet. In the present embodiment, the second communication unit 32 is a communication interface compliant with the Ethernet (registered trademark) standard and is connected to the router 6 by a LAN (Local Area Network) cable. The third communication unit 33 is a communication interface for communicating with the voice interface 5. In the present embodiment, the third communication unit 33 performs short-range wireless communication compliant with Bluetooth (registered trademark) with the voice interface 5.

[0027] The control unit 34 is configured to control each of the first communication unit 31, the second communication unit 32, and the third communication unit 33. When the control unit 34 receives a detection signal from the wiring device 1 at the first communication unit 31, the control unit 34 relays the received detection signal from the second communication unit 32 to the mobile terminal 7 and the server 8. Further, when the control unit 34 receives a detection signal from the wiring device 1 at the first communication unit 31, the control unit 34 relays the received detection signal from the third communication unit 33 to the voice interface 5.

[0028] The voice interface 5 is provided in the building where the wiring device 1 is installed. The voice interface 5 mainly includes, for example, a computer system (including a microcomputer) including a processor and a memory. That is, the computer system functions as the voice interface 5 by appropriately executing a program with the processor. The voice interface 5 receives a detection signal from the wiring device 1 by communicating with the third communication unit 33 of the receiving device 3. When the voice interface 5 receives a detection signal, the voice interface 5 reproduces information corresponding to the detection result included in the detection signal as voice from a speaker.

[0029] The mobile terminal 7 is a mobile information terminal such as a smartphone. The mobile terminal 7 mainly includes a computer system (including a microcomputer) having, for example, a processor and a memory. The mobile terminal 7 functions as a communication device that receives at least a detection signal from the wiring device 1 by installing dedicated application software and starting this application software. The mobile terminal 7 communicates with the second communication unit 32 of the receiving device 3 via the router 6. In this embodiment, the mobile terminal 7 performs short-range wireless communication compliant with Wi-Fi (registered trademark) with the router 6.

[0030] In this embodiment, in addition to the communication interface, the mobile terminal 7 includes a display unit such as a liquid crystal display and a speaker. When the mobile terminal 7 receives a detection signal from the wiring device 1 via the receiving device 3 and the router 6, it has a function of displaying information corresponding to the detection result included in the detection signal on the display or reproducing it as sound from the speaker.

[0031] The server 8 is provided in a facility owned by a place away from the building where the wiring device 1 is installed, for example, the provider of the wiring device 1 (such as a housing company) or the provider of the service using the wiring device 1 (such as a management company). The server 8 communicates with the second communication unit 32 of the receiving device 3 via a network N1 such as the Internet. In this embodiment, as the communication method between the server 8 and the receiving device 3, a wireless communication method using the network N1 is applied. The server 8 mainly includes a computer system (including a microcomputer) including, for example, a processor and a memory. That is, the computer system functions as the server 8 by appropriately executing a program with the processor.

[0032] When the server 8 receives a detection signal from the wiring device 1 via the receiving device 3, it has a function of displaying information corresponding to the detection result included in the detection signal on a display connected to the server 8 or playing it back as audio from a speaker connected to the server 8. Also, actually, the server 8 monitors a group of monitoring targets consisting of a plurality of buildings. In this case, a plurality of wiring devices 1 provided in a plurality of buildings belonging to the group of monitoring targets communicate with one server 8. In the present embodiment, for simplicity of explanation, the monitoring target of the server 8 is one wiring device 1 of one building. That is, in the present embodiment, the server 8 and the wiring device 1 are in a one-to-one relationship.

[0033] As described above, the voice interface 5, the mobile terminal 7, and the server 8 all receive the detection signal from the wiring device 1 via the receiving device 3 and have a function of displaying information corresponding to the detection result included in the detection signal or playing it back as audio. That is, in the wiring device system 100 of the present embodiment, the voice interface 5, the mobile terminal 7, and the server 8 are all output devices 4 that output information corresponding to the detection signal received by the receiving device 3. Here, the information corresponding to the detection result is, for example, a warning message indicating that an abnormality has occurred in the connection part 11 (here, an abnormality at the stage where the insulation performance of the connection part 11 deteriorates). The warning message is, for example, stored in advance in the output device 4 and is associated with the detection result included in the detection signal on a one-to-one basis.

[0034] (3) Operation Next, an example of the operation of the wiring device and the wiring device system according to the present embodiment will be described with reference to FIG. 2. In the following description, it is assumed that an abnormality occurs at the stage where the insulation performance of the connection part 11 of the wiring device 1 deteriorates as an abnormality related to the connection part 11. In this case, when the detection result (temperature) of the detection part 12 exceeds the threshold temperature, the processing part 14 determines that an abnormality related to the connection part 11 has been detected by the detection part 12 (step S101). Then, the processing part 14 executes the cutoff function (step S102). Further, the processing part 14 executes the communication function so as to transmit an abnormality related to the connection part 11 to the receiving device 3 as a detection signal including the detection result of the detection part 12 (step S103).

[0035] In the receiving device 3, the first communication part 31 receives the detection signal from the wiring device 1 (step S104). Then, the control part 34 relays the received detection signal to the output device 4 (step S105). In the present embodiment, the control part 34 relays the received detection signal from the second communication part 32 to the mobile terminal 7 and the server 8. Further, the control part 34 relays the received detection signal from the third communication part 33 to the voice interface 5.

[0036] When the output device 4 receives the detection signal from the receiving device 3 (step S106), it outputs information corresponding to the received detection signal (step S107). For example, when the voice interface 5 which is the output device 4 receives the detection signal, it reproduces a warning message such as "The wiring device is hot. Stop using the electrical equipment and replace the wiring device" from the speaker. Further, for example, in the mobile terminal 7 and the server 8 which are the output devices 4, when they receive the detection signal, they display the above warning message on the display or reproduce it from the speaker.

[0037] As described above, since the wiring device 1 of the present embodiment has a communication function, not only can the detection unit 12 detect the state of the environment in which it is placed, but it is also possible to transmit the detection result of the detection unit 12 to the receiving device 3 (external device 2). For this reason, the administrator of the wiring device 1 can obtain the detection result of the detection unit 12 through the receiving device 3. For example, when the administrator is around the voice interface 5, it is possible to obtain the detection result of the detection unit 12 by listening to the warning message reproduced by the voice interface 5. Also, for example, when the administrator owns the mobile terminal 7, it is possible to obtain the detection result of the detection unit 12 by looking at the display of the mobile terminal 7 or listening to the warning message reproduced by the mobile terminal 7. In this way, the administrator can grasp the state of the environment in which the wiring device 1 is placed without directly examining the wiring device 1. That is, in the present embodiment, there is an advantage that it is easy for the administrator of the wiring device 1 to grasp the state of the wiring device 1.

[0038] And, by grasping the state of the environment in which the wiring device 1 is placed, the administrator can take various measures. In the present embodiment, it is easy for the administrator to grasp the abnormality of the wiring device 1 at the stage when the insulation performance of the connection part 11 deteriorates. Therefore, for example, when the administrator is the housing company that provides the wiring device 1, the administrator can execute measures against the abnormality of the wiring device 1, such as dispatching an electrician to repair the wiring device 1 or replacing the wiring device 1 with a new one.

[0039] That is, the wiring device 1 of the present embodiment is different from a wiring device having only a power supply function like the outlet described in Patent Document 1. That is, since the wiring device 1 of the present embodiment has the function of transmitting the detection result of the detection unit 12 as described above, there is an advantage that further added value can be expected, not only the power supply function.

[0040] (4) Modification example The above embodiment is merely one of various embodiments of the present disclosure. The above embodiment can be variously modified according to design and the like as long as the object of the present disclosure can be achieved. Hereinafter, modification examples of the embodiment will be listed. The modification examples described below can be applied in appropriate combinations.

[0041] In the present embodiment, the abnormality detected by the detection unit 12 may be divided into a plurality of stages. And when the processing unit 14 detects, by the detection unit 12, an abnormality at a stage earlier than the stage at which the cutoff function is executed, the communication function may be executed. That is, the processing unit 14 may execute only the communication function before an abnormality at which the cutoff function should be executed occurs, instead of executing both the communication function and the cutoff function when an abnormality at which the cutoff function should be executed occurs. For example, when the detection unit 12 detects a first temperature, the processing unit 14 may execute the communication function, and when the detection unit 12 detects a second temperature higher than the first temperature, the processing unit 14 may execute the cutoff function. In this case, the administrator can grasp that some abnormality has occurred in the wiring device 1 when the detection unit 12 detects the first temperature, that is, at a stage even earlier than the stage at which the insulation performance of the connection unit 11 deteriorates.

[0042] In the present embodiment, the detection unit 12 detects an abnormality at a stage at which the insulation performance of the connection unit 11 deteriorates by detecting the temperature inside the housing of the wiring device 1, but the present disclosure is not limited to this. For example, the detection unit 12 may be configured to detect the current flowing through the connection unit 11 by a current sensor, or may be configured to detect the gas generated inside the housing of the wiring device 1 by a gas sensor. In any configuration, the detection unit 12 can detect an abnormality at a stage at which the insulation performance of the connection unit 11 deteriorates.

[0043] In this embodiment, the abnormality detected by the detection unit 12 relates to the deterioration of the insulation performance of the connection unit 11, but it is not intended to be limited thereto. For example, the abnormality detected by the detection unit 12 may be shaking of a predetermined seismic intensity or more due to an earthquake. This abnormality can be detected by the detection unit 12 having an acceleration sensor. Specifically, when the detection result (acceleration) by the acceleration sensor exceeds a predetermined acceleration set in advance, the processing unit 14 determines that an earthquake of a predetermined seismic intensity or more has occurred in the environment where the connection unit 11 is placed, and executes the communication function. At this time, it is preferable that the processing unit 14 also executes the cutoff function.

[0044] This configuration is effective, for example, when the administrator is a resident of the building and is away at a remote location. That is, since the seismic intensity that the administrator can know from the news or the like is the seismic intensity in a relatively wide area, it is difficult for the administrator to grasp whether there has been an earthquake that affects the building. On the other hand, with this configuration, the administrator can know that there has been shaking of a predetermined seismic intensity or more from the detection signal from the wiring device 1 installed in the building. For this reason, there is an advantage that it is easy for the administrator to grasp whether there has been an earthquake that affects the building.

[0045] Also, the abnormality detected by the detection unit 12 may be ultraviolet rays. This abnormality can be detected by the detection unit 12 having an ultraviolet sensor. Specifically, when the detection result (ultraviolet ray amount) by the ultraviolet sensor exceeds a predetermined ultraviolet ray amount set in advance, the processing unit 14 determines that the ultraviolet ray amount is relatively large in the environment where the connection unit 11 is placed, and executes the communication function.

[0046] This configuration is effective, for example, when the administrator is a resident of the building and the wiring device 1 is installed outdoors. That is, the wiring device 1 can prompt the residents in the building to pay attention according to the outdoor ultraviolet ray amount. For example, when the administrator owns the mobile terminal 7, the administrator can prepare the clothing for going out in advance by listening to a warning message such as "The ultraviolet ray amount is high, so wear a hat" reproduced by the mobile terminal 7.

[0047] In addition, the abnormality detected by the detection unit 12 may be a sound such as noise. This abnormality can be detected because the detection unit 12 has a sound sensor. Specifically, when the detection result (volume of a specific sound) by the sound sensor exceeds a predetermined volume set in advance, the processing unit 14 determines that some abnormality such as the intrusion of a suspicious person has occurred in the environment where the connection unit 11 is placed, and executes the communication function. Here, the specific sound is, for example, the sound of glass breaking, the sound of a person falling, etc. The sound sensor is preferably configured to mainly detect sounds in a specific frequency band (here, the sound of glass breaking, etc.).

[0048] This configuration is effective, for example, when the administrator is a resident of the building and the wiring device 1 is installed indoors. That is, in this configuration, for example, a resident who is away from the wiring device 1 such as outdoors can easily grasp that some abnormality such as the intrusion of a suspicious person or the fall of a cohabiting family member has occurred based on the detection signal from the wiring device 1.

[0049] Also, in this embodiment, the cutoff unit 15 is configured to cut off the electric path L1 under the control of the processing unit 14, but the present invention is not limited to this. For example, the cutoff unit 15 may be configured to cut off the electric path L1 without relying on the control by the processing unit 14 when detecting leakage of electricity. Also, the cutoff unit 15 may be configured to cut off the electric path L1 without relying on the control by the processing unit 14 when detecting overcurrent or short circuit. Leakage of electricity, overcurrent, or short circuit can all be detected by a current sensor (detection unit 12). In this case, when the current sensor detects the occurrence of any one of leakage of electricity, overcurrent, or short circuit, the processing unit 14 executes the communication function. The current sensor may be integrated with the device constituting the cutoff unit 15 or may be separate.

[0050] Here, the detection unit 12 only needs to have at least one of the above-described temperature sensor, current sensor, gas sensor, acceleration sensor, ultraviolet sensor, and sound sensor. That is, the detection unit 12 only needs to have a sensor corresponding to the state to be detected among the states of the environment where the connection unit 11 is placed. Also, the number of states detected by the detection unit 12 may be plural. For example, when the detection unit 12 has a temperature sensor and a sound sensor, the detection unit 12 detects the temperature inside the housing of the wiring device 1 and the indoor noise as the states of the environment where the connection unit 11 is placed.

[0051] By the way, in the wiring device 1, there may be a case where unique identification information such as a manufacturing number is assigned. In this case, the processing unit 14 may execute the communication function by including the identification information of the wiring device 1 to which it belongs in the detection signal. In other words, the detection signal may include the identification information for identifying the wiring device 1 that is the transmission source of the detection signal. This configuration is effective when there are a plurality of wiring devices 1. That is, in this configuration, it is easy for the administrator to grasp which wiring device 1 an abnormality has occurred in based on the detection signal from the wiring device 1.

[0052] Here, the identification information is preferably associated with the electrical device A1 connected to the wiring device 1 through setting work by, for example, a constructor or an administrator. For example, when the electrical device A1 is a refrigerator, the identification information of the wiring device 1 to which the refrigerator is connected is associated with the refrigerator. Then, the processing unit 14 includes the identification information and the information of the electrical device A1 associated with the identification information in the detection signal and executes the communication function. In this configuration, it is easy for the administrator to grasp the wiring device 1 in which an abnormality has occurred and the electrical device A1 connected to this wiring device 1 based on the detection signal from the wiring device 1.

[0053] In addition, when the wiring device 1 has a current sensor, the processing unit 14 may identify the electrical device A1 connected to the wiring device 1 from the waveform of the current flowing through the connection unit 11 by using, for example, disaggregation technology or the like. That is, the processing unit 14 may automatically identify the electrical device A1 connected to the wiring device 1 and associate the identified electrical device A1 with the identification information. In this case, the operation of associating the identification information with the electrical device A1 connected to the wiring device 1 is unnecessary.

[0054] In the present embodiment, the communication between the wiring device 1 and the receiving device 3 (external device 2) is one-way communication from the wiring device 1 to the receiving device 3, but may also be two-way communication. Specifically, the communication unit 13 may be configured to receive a response signal to the detection signal from the receiving device 3 (external device 2). And the predetermined condition for the processing unit 14 to execute the cutoff function may include the communication unit 13 receiving the response signal. That is, the processing unit 14 does not execute the cutoff function even if an abnormality is detected by the detection unit 12, and executes the cutoff function after receiving the response signal.

[0055] With this configuration, after the administrator confirms the detection signal from the wiring device 1, the administrator can cut off the circuit L1 of the wiring device 1 according to his or her own judgment by performing a remote operation of transmitting a response signal to the wiring device 1 via the mobile terminal 7 or the server 8. Also, when the voice interface 5 is a voice assistant device (described later), the administrator can also cut off the circuit L1 of the wiring device 1 by performing an operation by voice via the voice interface 5.

[0056] In this embodiment, the voice interface 5 may be a voice assistant device having a function of recognizing human voice. In this case, the voice interface 5 may be configured to analyze the voice uttered by the administrator and transmit a control signal corresponding to the analysis result to the wiring device 1 via the receiving device 3. For example, assume that the administrator utters a voice "Stop using the wiring device of the air conditioner". Then, the voice interface 5 analyzes this voice and generates a control signal including a command for instructing the interruption of the electric circuit L1 of the wiring device 1 to which the air conditioner is connected. Then, the voice interface 5 transmits the generated control signal to the wiring device 1 to which the air conditioner is connected via the receiving device 3. When the processing unit 14 of the wiring device 1 to which the air conditioner is connected receives the control signal from the voice interface 5, it executes the interruption function. With this configuration, it is possible to remotely operate the wiring device 1 using the voice interface 5.

[0057] Here, the processing unit 14 may have a detection mode that is triggered by a control signal from the receiving device 3 (external device 2). Then, in the detection mode, when the detection unit 12 detects that the state of the environment where the connection unit 11 is placed is out of a preset range, the processing unit 14 may execute the communication function. Specific examples will be described below. In the following, it is assumed that the voice interface 5 is a voice assistant device and is installed in the living room. Also, in the following, it is assumed that the wiring device 1 is installed in the dressing room and the wiring device 1 has a temperature sensor as the detection unit 12.

[0058] For example, an administrator issues a voice such as "taking a bath" towards the voice interface 5. Then, the voice interface 5 analyzes this voice and transmits a control signal corresponding to the analysis result to the wiring device 1 in the dressing room via the receiving device 3. When the processing unit 14 of the wiring device 1 in the dressing room receives the control signal, it shifts to the detection mode. The detection unit 12 detects the temperature of the dressing room as the state of the environment where the wiring device 1 is placed. And in the detection mode, the processing unit 14 determines whether the state of the environment where the connection unit 11 is placed is out of a preset range (here, whether the temperature of the dressing room is lower than a predetermined temperature).

[0059] When the processing unit 14 determines that the temperature of the dressing room is lower than the predetermined temperature, it includes that fact in the detection signal and executes the communication function. When the voice interface 5 receives the detection signal from the wiring device 1, it plays a warning message such as "The temperature of the dressing room has become low". With this configuration, the administrator can know before taking a bath that the temperature of the dressing room has become low, so it is easy to prevent the occurrence of heat shock. In the above specific example, the voice interface 5 is the transmission source of the control signal, but the mobile terminal 7 may be the transmission source of the control signal.

[0060] In this embodiment, when the processing unit 14 detects an abnormality related to the connection unit 11 by the detection unit 12, it executes the communication function, but the intention is not limited to this. For example, the processing unit 14 may execute the communication function regularly regardless of whether an abnormality has occurred in the connection unit 11. In this case, the administrator can monitor the environment where the wiring device 1 is placed through the receiving device 3 (external device 2).

[0061] Also, when the detection unit 12 has a current sensor, the detection unit 12 can indirectly detect the operating state of the electrical device A1 connected to the connection unit 11 by detecting the current flowing through the connection unit 11. And the processing unit 14 may execute the communication function regularly regardless of whether an abnormality has occurred in the connection unit 11. In this case, the administrator can regularly grasp the operating state of the electrical device A1.

[0062] In this embodiment, the blocking unit 15 has a switch for returning the electric path L1 from the blocked state to the original state, but whether or not to provide this switch is optional. For example, the blocking unit 15 may be configured not to return to the original state once the electric path L1 is blocked.

[0063] In this embodiment, the wiring device 1 may include a light emitting unit having a light emitting element such as a speaker or a light emitting diode. In this case, when the detection unit 12 detects an abnormality, the processing unit 14 may perform control to notify the surroundings of the abnormality, for example, by playing sound from the speaker or causing the light emitting unit to emit light. With this configuration, it is possible to notify people around the wiring device 1 of the occurrence of an abnormality.

[0064] The wiring device 1 is not limited to indoor use, and may be outdoor use, for example, used outside a building such as a parking lot. Also, the wiring device 1 is not limited to an outlet without a grounding electrode, and may be an outlet with a grounding electrode. Also, the wiring device 1 is not limited to an outlet for AC 100V, and may be, for example, an outlet for AC 200V or DC. Further, the wiring device 1 is not limited to an A-type outlet, and may be an outlet to which a plug having pin-shaped plug blades, such as a B-type or C-type, can be connected. In addition, the wiring device 1 is not limited to a two-outlet type outlet, and may be, for example, a one-outlet type or three-outlet type outlet.

[0065] Also, the wiring device 1 is not limited to the above-described outlet, and may be, for example, an information outlet to which a connector of a LAN (Local Area Network) cable can be connected, or a USB (Universal Serial Bus) outlet or the like. That is, the wiring device 1 only needs to have a connection portion 11 to which the electric device A1 can be electrically connected. And the wiring device 1 may be used to supply power from the power source B1 to the electric device A1 as in this embodiment, or may be used to connect the electric device A1 to the network N1.

[0066] The communication method between the wiring device 1 and the receiving device 3 is not limited to specific low-power radio, and may be other wireless communications such as Bluetooth (registered trademark), Wi-Fi (registered trademark), etc. Further, the communication method between the wiring device 1 and the receiving device 3 may be a wired communication method such as power line carrier communication (Power Line Communication), for example.

[0067] In the present embodiment, the receiving device 3 may be a local device used, for example, in a HEMS (Home Energy Management System). Further, in the present embodiment, the receiving device 3 and the output device 4 may be configured as one device. For example, the mobile terminal 7 may be configured to receive a detection signal from the wiring device 1 without passing through the receiving device 3 as the external device 2. In this case, the communication method between the communication unit 13 of the wiring device 1 and the mobile terminal 7 is wireless communication such as Wi-Fi (registered trademark), for example.

[0068] In the present embodiment, the mobile terminal 7 communicates with the receiving device 3 via the router 6 by Wi-Fi (registered trademark), but is not intended to be limited thereto. For example, the mobile terminal 7 may be configured to communicate with the receiving device 3 via the network N1 without passing through the receiving device 3. In this case, the mobile terminal 7 is connected to the network N1 via a mobile phone network (carrier network) provided by a communication carrier. Examples of the mobile phone network include a 3G (third generation) line, an LTE (Long Term Evolution) line, etc. Further, the mobile terminal 7 may be connected to the network N1 via a public wireless LAN.

[0069] In the present embodiment, the server 8 may have a function of transmitting a signal to the wiring device 1. For example, the server 8 may have a function of transmitting a signal for alive check (survival confirmation) to the wiring device 1, a signal for inquiring about the state of the wiring device 1, a signal for controlling the processing unit 14 of the wiring device 1, etc.

[0070] The wiring device system 100 of the present embodiment includes a voice interface 5, a mobile terminal 7, and a server 8 as output devices 4, but is not limited thereto. For example, the wiring device system 100 may include at least one of the voice interface 5, the mobile terminal 7, and the server 8.

For example, the wiring device system 100 may include a plurality of wiring devices 1. Also, there may be a plurality of electrical devices A1 connected to the wiring device 1.

The computer system mainly includes a processor and a memory as hardware. By the processor executing a program recorded in the memory of the computer system, the function as the execution entity of the device or system in the present disclosure is realized.
