Detailed Description
(1) Summary of the invention
The wiring device 1 and the wiring device system 100 according to the embodiment will be described in brief with reference to fig. 1. In fig. 1, the dotted line represents the movement of the signal. In the present embodiment, the wiring appliance 1 has a function of a socket (Outlet) to which a plug of the electrical device a1 is connected and which supplies power to the electrical device a 1. Here, it is assumed that the wiring device 1 is for ac 100V and is a 2-position outlet capable of simultaneously connecting 2 plugs. In the present embodiment, it is assumed that the wiring device 1 is an indoor socket attached to an inner wall of a building. Examples of the building in which the wiring device 1 is installed include a single residence, a collective residence, a factory, a business office, a store, and a nursing facility.
The wiring device 1 of the present embodiment includes a processing unit 14, a connection unit 11, a detection unit 12, and a communication unit 13. The connection portion 11 can be electrically connected to the electrical device a 1. In the present embodiment, the plug of the electrical device a1 is connected to the connection portion 11 of the wiring appliance 1, whereby the power supply from the power supply B1 to the electrical device a1 can be realized via the wiring appliance 1. In the present embodiment, the wiring device 1 is used for supplying electric power to various electrical devices a1 such as lighting equipment, air conditioning equipment, and refrigerators.
The detection unit 12 detects the state of the placement environment of the connection unit 11. 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 in which the connection unit 11 is placed. 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 in which the connection unit 11 is placed. The communication unit 13 can communicate with an external device 2 (here, the receiving device 3) different from the electrical appliance a 1. The processing unit 14 has a communication function of controlling the communication unit 13 to transmit a detection signal including a detection result of the detection unit 12 to the external device 2.
As described above, since the wiring device 1 of the present embodiment has a communication function, it is possible not only to detect the state of the own placement environment by the detection unit 12, but also to transmit the detection result of the detection unit 12 to the external apparatus 2. Therefore, for example, a manager of the wiring device 1, such as a resident of a building in which the wiring device 1 is installed, can grasp the state of the placement environment of the wiring device 1 without directly inspecting the wiring device 1 by acquiring the detection result of the detection unit 12 by the external device 2. That is, the present embodiment has the following advantages: the manager of the wiring device 1 can easily grasp the state of the wiring device 1.
(2) Details of
The wiring device 1 and the wiring device system 100 according to the present embodiment will be described in detail below with reference to fig. 1. The wiring device system 100 of the present embodiment includes a wiring device 1, a receiving device 3 as an external device 2, an audio interface 5 as an output device 4, a portable terminal 7, and a server 8. The wiring device 1 further includes a cutting unit 15 in addition to the above-described connection unit 11, detection unit 12, communication unit 13, and processing unit 14. In the present embodiment, the connection unit 11, the detection unit 12, the communication unit 13, the processing unit 14, and the cutting unit 15 are all housed in the housing of the wiring device 1.
The connection portion 11 is, for example, a blade support member connected to a plug of the electrical apparatus a 1. The connection unit 11 is electrically connected to a power supply B1 such as a commercial power supply, for example, via an electric wire. Therefore, the electrical device a1 is electrically connected to the power supply B1 via the connection unit 11 by connecting the plug to the connection unit 11. The power source B1 supplies electric power to the electrical device a1 connected to the connection unit 11.
The detection unit 12 is configured to detect an abnormality related to the connection unit 11 as a state of a placement environment of the connection unit 11. In the present embodiment, the detection unit 12 includes a temperature sensor that detects the temperature in the housing of the wiring device 1. For example, if the contact resistance of the connection portion 11 increases due to mechanical abnormality caused by insertion and removal of a plug more than the expected number of times of use, adhesion of foreign matter such as dust to the connection portion 11, or the like, the temperature in the housing of the wiring device 1 increases due to an increase in the amount of heat generation of the connection portion 11. The detection unit 12 can detect an electrical abnormality such as a life of the wiring device 1 or a decrease in insulation performance of the wiring device 1 as an abnormality related to the connection unit 11 by detecting the temperature increase with a temperature sensor. The temperature sensor is preferably provided at a portion where the temperature is likely to increase if an abnormality occurs, for example, in the vicinity of the connection portion 11.
In the present embodiment, the abnormality is related to a decrease in the insulation performance of the connection portion 11. At the stage when the insulation performance of the connection portion 11 is lowered, the temperature in the housing of the wiring device 1 is raised as compared with the normal case. Therefore, by detecting the temperature that rises as compared with the normal state by the detection unit 12, it is possible to detect an abnormality at the stage where the insulation performance of the connection unit 11 is reduced.
The communication unit 13 is a communication interface for communicating with a first communication unit 31 (described later) of the reception device 3. In the present embodiment, the communication unit 13 is a low power wireless communication interface that does not require permission of a radio station. Such low power wireless communication is defined in various countries by specifications such as frequency bands used for applications and antenna power. In japan, low frequency radio (specific low frequency radio) using radio waves of the 920MHz band or the 420MHz band is specified.
The processing unit 14 controls the detection unit 12, the communication unit 13, and the disconnection unit 15. In the present embodiment, the processing unit 14 is constituted by a microcomputer having a processor and a memory as main components. The same applies to the control unit 34 of the receiving apparatus 3 described later. That is, the processing unit 14 (control unit 34) is realized by a computer system having a processor and a memory. The computer system functions as the processing unit 14 (control unit 34) by executing an appropriate program by the processor. The program may be recorded in advance in a memory, or may be provided via a telecommunication line such as a network, or may be recorded in a recording medium such as a memory card.
The processing unit 14 is configured to acquire a detection result from the detection unit 12. In the present embodiment, the processing unit 14 acquires the temperature in the housing of the wiring device 1 detected by the detection unit 12 as a detection result. 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 "equal to or higher than the threshold temperature"), the processing unit 14 determines that the detection unit 12 detects an abnormality related to the connection unit 11. Here, the processing unit 14 determines that the detection unit 12 detects an abnormality at the stage where the insulation performance of the connection unit 11 is degraded. At this time, the processing unit 14 generates a detection signal including an abnormality related to the connection unit 11 as a detection result of the detection unit 12. 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 the following communication functions: the communication unit 13 is controlled to transmit the detection signal to the receiving device 3 (external device 2).
When determining that the detection unit 12 detects an abnormality in the connection unit 11, the processing unit 14 executes the disconnection function. The cutting function is a function of cutting off the circuit L1 (described later) by controlling the cutting unit 15. In other words, the processing unit 14 has the following cutoff function: when a predetermined condition is satisfied, the cutting unit 15 is controlled to cut off the circuit L1. In the present embodiment, the predetermined condition includes that the detection unit 12 detects an abnormality related to the connection unit 11. In the present embodiment, when the detection unit 12 detects an abnormality, the processing unit 14 executes the shut-off function. That is, in the present embodiment, only the detection of an abnormality by the detection unit 12 is defined as a predetermined condition. When the detection unit 12 detects an abnormality, the processing unit 14 may execute the cutoff function immediately or after a fixed time.
The cutting section 15 is housed in the housing of the wiring device 1. The cut-off portion 15 is connected between the connection portion 11 and the power supply B1. The disconnecting unit 15 includes a contact for electrically connecting the connecting unit 11 and the power source B1, and a movable element for opening or closing the contact. The cutting unit 15 is controlled by the processing unit 14 to operate the movable element to open the contact. Thus, the disconnecting unit 15 disconnects the circuit L1 between the connection unit 11 and the power supply B1. The circuit L1 is a power supply path from the power source B1 to the connection unit 11 (or the electrical device a1 connected to the connection unit 11).
In the present embodiment, the disconnecting unit 15 includes a switch for returning the state of the disconnecting circuit L1 to the original state. The switch is provided to be exposed from a housing of the wiring tool 1, for example. Therefore, in the state where the electric circuit L1 is disconnected, the disconnection of the disconnecting section 15 is released by, for example, a human operating a switch, and the electric circuit L1 returns to the original state.
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 supply B1 via a circuit different from the circuit L1. The power supply unit receives the power supply from the power supply B1 to generate operating power, and supplies the generated operating power to the detection unit 12, the communication unit 13, and the processing unit 14. Therefore, the detection unit 12, the communication unit 13, and the processing unit 14 operate regardless of whether or not the circuit L1 is opened or closed (that is, even in a state where the circuit L1 is cut by the cutting unit 15).
The receiving device 3 is installed in, for example, a building in which the wiring harness 1 is installed. In the present embodiment, the receiving device 3 is the external device 2 and receives the detection signal from the wiring tool 1. The receiving device 3 includes a first communication unit 31, a second communication unit 32, a third communication unit 33, and a control unit 34.
The first communication unit 31 is a communication interface for communicating with the communication unit 13 of the wiring tool 1. In the present embodiment, the first communication unit 31 is a low power wireless communication interface that does not require permission of a radio station. The second communication unit 32 is a communication interface for communicating with the mobile terminal 7 or the server 8 via the router 6 or the network N1 such as the internet. In the present embodiment, the second communication unit 32 is a communication interface conforming to 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 audio interface 5. In the present embodiment, the third communication unit 33 performs short-range wireless communication conforming to Bluetooth (registered trademark) with the audio interface 5.
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 first communication unit 31 receives the detection signal from the wiring tool 1, the control unit 34 relays the received detection signal from the second communication unit 32 to the portable terminal 7 or the server 8. When the first communication unit 31 receives the detection signal from the wiring tool 1, the control unit 34 relays the received detection signal from the third communication unit 33 to the audio interface 5.
The sound interface 5 is installed in, for example, a building in which the wiring harness 1 is installed. The audio interface 5 is mainly configured by a computer system (including a microcomputer) including a processor and a memory, for example. That is, the computer system functions as the audio interface 5 by the processor executing an appropriate program. The audio interface 5 receives the detection signal from the wiring tool 1 by communicating with the third communication unit 33 of the receiving device 3. When receiving the detection signal, the sound interface 5 plays information corresponding to the detection result included in the detection signal by sound from the speaker.
The mobile terminal 7 is a mobile information terminal such as a smart phone. The portable terminal 7 is mainly configured by a computer system (including a microcomputer) having a processor and a memory, for example. The portable terminal 7 is installed with dedicated application software and starts the application software, thereby functioning as at least a communication device that receives the detection signal from the wiring harness 1. The portable terminal 7 communicates with the second communication unit 32 of the reception apparatus 3 via the router 6. In the present embodiment, the mobile terminal 7 and the router 6 perform short-range wireless communication conforming to Wi-Fi (registered trademark).
In the present embodiment, the portable terminal 7 includes a display unit such as a liquid crystal display and a speaker in addition to the communication interface. The portable terminal 7 has the following functions: when the detection signal from the wiring harness 1 is received via the receiving device 3 and the router 6, information corresponding to the detection result included in the detection signal is displayed on a display, or information corresponding to the detection result included in the detection signal is reproduced by sound from a speaker.
The server 8 is installed in a place separate from the building in which the wiring device 1 is installed, for example, a facility owned by a source (home company or the like) for providing the wiring device 1 or a source (management company or the like) for providing a service using the wiring device 1. The server 8 communicates with the second communication unit 32 of the reception apparatus 3 via a network N1 such as the internet. In the present embodiment, as a communication method between the server 8 and the receiving apparatus 3, a wireless communication method using the network N1 is applied. The server 8 is mainly configured by a computer system (including a microcomputer) including a processor and a memory, for example. That is, the computer system functions as the server 8 by executing an appropriate program by the processor.
The server 8 has the following functions: when the detection signal from the wiring harness 1 is received via the receiving device 3, information corresponding to the detection result included in the detection signal is displayed on a display connected to the server 8, or information corresponding to the detection result included in the detection signal is reproduced by sound from a speaker connected to the server 8. The server 8 actually sets a monitoring target group including a plurality of buildings as a monitoring target. At this time, a plurality of wiring harnesses 1 installed in a plurality of buildings belonging to the monitoring target group communicate with 1 server 8. In the present embodiment, for convenience of explanation, the monitoring target of the server 8 is 1 wiring appliance 1 of 1 building. That is, in the present embodiment, the server 8 and the wiring harness 1 are in a 1-to-1 relationship.
As described above, the audio interface 5, the portable terminal 7, and the server 8 each have the following functions: the detection signal from the wiring tool 1 is received via the receiving device 3, and information corresponding to the detection result included in the detection signal is displayed or reproduced by sound. That is, in the wiring tool system 100 of the present embodiment, any of the audio interface 5, the mobile terminal 7, and the server 8 is the output device 4 that outputs 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 or the like indicating that an abnormality related to the connection portion 11 (here, an abnormality at a stage where the insulation performance of the connection portion 11 is degraded) has occurred. The warning message is stored in the output device 4 in advance, for example, and is associated with the detection result 1 included in the detection signal for 1.
(3) Movement of
An example of the operation of the wiring tool 1 and the wiring tool system 100 according to the present embodiment will be described below with reference to fig. 2. In the following description, as an abnormality related to the connection portion 11 of the wiring device 1, it is assumed that an abnormality at a stage where the insulation performance of the connection portion 11 is degraded occurs. In this case, since the detection result (temperature) of the detection unit 12 exceeds the threshold temperature, the processing unit 14 determines that the detection unit 12 detects an abnormality related to the connection unit 11 (step S101). Then, the processing unit 14 executes the cutoff function (step S102). Further, the processing unit 14 executes a communication function to transmit a detection signal including an abnormality related to the connection unit 11 as a detection result of the detection unit 12 to the reception device 3 (step S103).
In the receiving device 3, the first communication unit 31 receives the detection signal from the wiring tool 1 (step S104). In this way, the control unit 34 relays the received detection signal to the output device 4 (step S105). In the present embodiment, the control unit 34 relays the received detection signal from the second communication unit 32 to the mobile terminal 7 and the server 8. The control unit 34 relays the received detection signal from the third communication unit 33 to the audio interface 5.
When receiving the detection signal from the receiving device 3 (step S106), the output device 4 outputs information corresponding to the received detection signal (step S107). For example, the audio interface 5 as the output device 4 plays "the wiring tool generates heat from the speaker when receiving the detection signal. And a warning message such as "stop the use of the electrical equipment and replace the wiring tool". For example, in the mobile terminal 7 and the server 8 as the output device 4, when the detection signal is received, the warning message is displayed on the display or played back from the speaker.
As described above, since the wiring device 1 of the present embodiment has a communication function, not only the detection unit 12 detects the state of the own placement environment, but also the detection result of the detection unit 12 can be transmitted to the receiving device 3 (external device 2). Therefore, the manager of the wiring tool 1 can acquire the detection result of the detection unit 12 through the receiving device 3. For example, when the administrator is located around the audio interface 5, the administrator can acquire the detection result of the detection unit 12 by hearing the warning message played by the audio interface 5. For example, when the administrator owns the mobile terminal 7, the administrator can acquire the detection result of the detection unit 12 by observing the display of the mobile terminal 7 or by hearing a warning message played by the mobile terminal 7. Thus, the manager can grasp the state of the placement environment of the wiring tool 1 without directly checking the wiring tool 1. That is, the present embodiment has the following advantages: the manager of the wiring device 1 can easily grasp the state of the wiring device 1.
The manager can take various measures by grasping the state of the environment in which the wiring tool 1 is placed. In the present embodiment, the manager can easily recognize the abnormality of the wiring device 1 at the stage where the insulation performance of the connection portion 11 is degraded. Therefore, for example, in the case where the manager is a home company that is a source of supply of the wiring device 1, the manager can perform a countermeasure against an abnormality of the wiring device 1, such as dispatching an electric worker to repair the wiring device 1, or replacing the wiring device 1 with a new one.
That is, the wiring device 1 of the present embodiment is different from a wiring device having only a power supply function, such as a socket described in patent document 1. That is, the wiring device 1 of the present embodiment has the following advantages because it has the function of transmitting the detection result of the detection unit 12 as described above: further added value can be expected in addition to the power supply function.
(4) Modification example
The above embodiments are merely examples of various embodiments of the present invention. The above embodiment can be variously modified according to design and the like as long as the object of the present invention can be achieved. Modifications of the embodiment are described below. The modifications described below can be applied in combination as appropriate.
In the present embodiment, the abnormality detected by the detection unit 12 may be divided into a plurality of stages. The processing unit 14 may execute the communication function when the detection unit 12 detects an abnormality at a stage earlier than the abnormality at the stage of executing the shut-off function. That is, the processing unit 14 may execute only the communication function before an abnormality occurs in which the disconnection function is to be executed, instead of executing both the communication function and the disconnection function when the abnormality occurs in which the disconnection function is to be executed. For example, the processing unit 14 may execute the communication function when the inspection unit 12 detects a first temperature and execute the disconnection function when a second temperature higher than the first temperature is detected. In this case, the manager can recognize that some abnormality has occurred in the wiring device 1 when the detection unit 12 detects the first temperature, that is, at a stage earlier than the stage at which the insulation performance of the connection unit 11 is degraded.
In the present embodiment, the detection unit 12 detects the temperature in the housing of the wiring device 1 to detect an abnormality at the stage where the insulation performance of the connection unit 11 is reduced. 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 in the housing of the wiring device 1 by a gas sensor. In any of the configurations, the detection unit 12 can detect an abnormality at a stage where the insulation performance of the connection unit 11 is reduced.
In the present embodiment, the abnormality detected by the detection unit 12 is related to a decrease in the insulation performance of the connection unit 11, but the present invention is not limited thereto. For example, the abnormality detected by the detection unit 12 may be a shake of a predetermined magnitude or more caused by an earthquake. The abnormality can be detected by the detection unit 12 having an acceleration sensor. Specifically, when the detection result (acceleration) of the acceleration sensor exceeds a predetermined acceleration set in advance, the processing unit 14 determines that an earthquake having a predetermined magnitude or more has occurred in the environment in which the connecting unit 11 is placed, and executes the communication function. In this case, the processing unit 14 preferably performs the cutting function together.
This structure is effective, for example, when the manager is the resident of the building and the manager is out to a remote place. That is, since the earthquake magnitude that the manager can know through news and the like is an earthquake magnitude in a wide range, it is difficult for the manager to know whether there is an earthquake that affects the building in which the manager lives. On the other hand, in this configuration, the manager can recognize that there is a vibration of a predetermined magnitude or more by a detection signal from the wiring tool 1 installed in the building. Therefore, the following advantages are provided: the manager can easily grasp whether there is an earthquake that affects the degree of the building in which the manager lives.
The abnormality detected by the detector 12 may be ultraviolet light. The abnormality can be detected by the detection unit 12 having an ultraviolet sensor. Specifically, when the detection result (the amount of ultraviolet light) of the ultraviolet sensor exceeds a predetermined amount of ultraviolet light set in advance, the processing unit 14 determines that the amount of ultraviolet light is large in the environment where the connection unit 11 is placed, and executes the communication function.
This structure is effective, for example, when the manager is the resident of the building and the wiring device 1 is installed outdoors. That is, the wiring device 1 can give a reminder to the resident who is located in the building in accordance with the amount of ultraviolet rays outside. For example, when the administrator owns the mobile terminal 7, the administrator can prepare clothing and the like for going out in advance by hearing a warning message such as "please put on a hat because of a large amount of ultraviolet rays" played back by the mobile terminal 7.
The abnormality detected by the detection unit 12 may be a sound such as noise. The abnormality can be detected by the detection unit 12 having an acoustic sensor. Specifically, when the detection result of the sound sensor (the volume of the specific sound) exceeds a predetermined volume set in advance, the processing unit 14 determines that some abnormality such as intrusion of a suspicious person has occurred in the environment in which the connection unit 11 is placed, and executes the communication function. Here, the specific sound is, for example, a sound of glass breakage, a sound of a person falling, or the like. The sound sensor is preferably configured to mainly detect sound in a specific frequency band (here, sound of glass breakage or the like).
This structure is effective, for example, when the manager is the resident of the building and the wiring device 1 is installed indoors. That is, in this configuration, it is easy for a resident who is located in a place separated from the wiring device 1, such as outdoors, to recognize that some abnormality, such as intrusion of a suspicious person or falling of a resident who is living, has occurred, based on the detection signal from the wiring device 1.
In the present embodiment, the cutting unit 15 is configured to cut the circuit L1 under the control of the processing unit 14, but the present invention is not limited thereto. For example, the cutting unit 15 may be configured to cut off the circuit L1 without depending on the control of the processing unit 14 when the leakage is detected. The cutting unit 15 may be configured to cut off the circuit L1 without depending on the control of the processing unit 14 when an overcurrent or a short circuit is detected. The current sensor (detection unit 12) can detect any of leakage, overcurrent, and short circuit. At this time, when the current sensor detects any one of the occurrence of the leakage, the overcurrent, and the short circuit, the processing unit 14 executes the communication function. The current sensor may be integrated with the device constituting the cutting unit 15 or may be independent of the device.
Here, the detection unit 12 may include at least 1 of the temperature sensor, the current sensor, the gas sensor, the acceleration sensor, the ultraviolet sensor, and the sound sensor. That is, the detection unit 12 may have a sensor corresponding to a state to be detected in the state of the environment in which the connection unit 11 is placed. In addition, a plurality of states may be detected by the detection unit 12. For example, in the case where the detection unit 12 includes a temperature sensor and an acoustic sensor, the detection unit 12 detects the temperature in the housing of the wiring device 1 and the noise in the room as the state of the environment in which the connection unit 11 is placed.
In addition, the wiring device 1 may be assigned unique identification information such as a manufacturing number, for example. In this case, the processing unit 14 may include identification information of the wiring tool 1 to which the processing unit belongs in the detection signal to execute the communication function. In other words, the detection signal may include identification information for identifying the wiring device 1 of the transmission source of the detection signal. This structure is effective when a plurality of wiring harnesses 1 are present. That is, in this configuration, the manager can easily grasp which wiring tool 1 has an abnormality based on the identification information included in the detection signal from the wiring tool 1.
Here, it is preferable that the identification information is associated with the electrical equipment a1 connected to the wiring appliance 1 by, for example, a setting operation by a constructor or a manager. For example, in the case where the electrical appliance a1 is a refrigerator, the identification information of the wiring appliance 1 connected to the refrigerator 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, the manager can easily recognize the wiring tool 1 in which the abnormality has occurred and the electrical equipment a1 connected to the wiring tool 1, based on the detection signal from the wiring tool 1.
When the wiring device 1 includes a current sensor, the processing unit 14 may determine the electrical equipment a1 connected to the wiring device 1 from the waveform of the current flowing through the connection unit 11 using, for example, a disaggregation (disaggregation) technique. That is, processing unit 14 may automatically specify electrical device a1 connected to wiring harness 1 and associate the specified electrical device a1 with the identification information. In this case, the work of associating the identification information with the electrical device a1 connected to the wiring harness 1 is not necessary.
In the present embodiment, the communication between the wiring harness 1 and the receiving device 3 (external device 2) is unidirectional communication from the wiring harness 1 to the receiving device 3, but bidirectional communication may be used. 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). The predetermined condition for executing the shutdown function by the processing unit 14 may further include the communication unit 13 receiving a response signal. That is, the processing unit 14 does not perform the shutoff function even when the detection unit 12 detects an abnormality, but performs the shutoff function after receiving the response signal.
In this configuration, after confirming the detection signal from the wiring device 1, the administrator performs a remote operation of transmitting a response signal to the wiring device 1 via the mobile terminal 7 or the server 8, thereby cutting off the circuit L1 of the wiring device 1 according to the judgment of the administrator himself. In addition, when the audio interface 5 is a voice assistant device (described later), the manager can also cut off the circuit L1 of the wiring device 1 by performing an operation using voice through the audio interface 5.
In the present embodiment, the audio interface 5 may be an audio assistant device having a function of recognizing a voice uttered by a person. In this case, the audio interface 5 may be configured to analyze the sound generated by the administrator and transmit a control signal corresponding to the analysis result to the wiring tool 1 via the receiving device 3. For example, the manager may sound "stop the air conditioner from using the wiring device". Then, the audio interface 5 analyzes the sound and generates a control signal including a command for instructing disconnection of the circuit L1 of the wiring appliance 1 connected to the air conditioner. Then, the audio interface 5 transmits the generated control signal to the wiring device 1 connected to the air conditioner via the receiving device 3. The processing unit 14 of the wiring tool 1 connected to the air conditioner executes the shut-off function when receiving the control signal from the audio interface 5. In this configuration, the wiring tool 1 can be remotely operated using the audio interface 5.
Here, the processing unit 14 may have a detection mode that is executed by using a control signal from the receiving apparatus 3 (external apparatus 2) as a trigger. In the detection mode, the processing unit 14 may execute the communication function when the detection unit 12 detects that the state of the environment in which the connection unit 11 is placed is out of a predetermined range. Specific examples will be described below. In the following, it is assumed that the sound interface 5 is a sound assistant device and is provided in the living room. In the following, it is assumed that wiring tool 1 is installed in a changing room, and wiring tool 1 has a temperature sensor as detection unit 12.
For example, the manager makes a sound such as "bath" to the sound interface 5. Then, the audio interface 5 analyzes the sound, and transmits a control signal according to the analysis result to the wiring tool 1 located in the dressing room via the receiving device 3. The processing unit 14 of the wiring device 1 located in the dressing room shifts to the detection mode when receiving the control signal. The detection unit 12 detects the temperature of the dressing room as the state of the environment in which the wiring tool 1 is placed. In the detection mode, the processing unit 14 determines whether or not the state of the environment in which the connection unit 11 is placed is out of a predetermined range (here, whether or not the temperature of the dressing room is lower than a predetermined temperature).
When determining that the temperature of the dressing room is lower than the predetermined temperature, the processing unit 14 includes the determination in the detection signal and executes the communication function. The sound interface 5 plays a warning message such as "the temperature in the changing room is low" when receiving the detection signal from the wiring tool 1. In this configuration, the manager can know that the temperature of the dressing room is low before taking a bath, and thus can easily prevent the occurrence of heat shock (Japanese: ヒートショック). In the above-described specific example, the audio interface 5 is a source of the control signal, but the mobile terminal 7 may be a source of the control signal.
In the present embodiment, the processing unit 14 executes the communication function when the detection unit 12 detects an abnormality in the connection unit 11, but the present invention is not limited to this. For example, the processing unit 14 may periodically execute the communication function regardless of whether or not an abnormality occurs in the connection unit 11. At this time, the manager can monitor the placement environment of the wiring tool 1 through the receiving device 3 (external device 2).
In the case where detecting unit 12 includes a current sensor, detecting unit 12 can indirectly detect the operating state of electrical device a1 connected to connecting unit 11 by detecting the current flowing through connecting unit 11. The processing unit 14 may periodically execute the communication function regardless of whether or not an abnormality occurs in the connection unit 11. At this time, the manager can periodically grasp the operating state of electrical device a 1.
In the present embodiment, the disconnecting unit 15 has a switch for returning from the state of the disconnecting circuit L1 to the original state, but the presence or absence of this switch is arbitrary. For example, the cutting unit 15 may be configured not to return to the original state when the circuit L1 is cut.
In the present embodiment, the wiring tool 1 may include a speaker or a light emitting unit having a light emitting element such as a light emitting diode. At this time, the processing unit 14 may perform the following control: when the detection unit 12 detects an abnormality, the processing unit 14 reports the abnormality to the surroundings by, for example, playing a sound from a speaker or emitting light from a light emitting unit. In this configuration, it is possible to make the person located around the wiring device 1 aware of the occurrence of an abnormality.
The wiring device 1 is not limited to indoor use, and may be outdoor use used outside a building such as a parking lot. The wiring device 1 is not limited to a socket having no ground electrode, and may be a socket having a ground electrode. The wiring device 1 is not limited to an ac 100V outlet, and may be, for example, an ac 200V outlet or a dc outlet. The wiring device 1 is not limited to the a-type socket, and may be a socket to which a plug having a pin-shaped blade can be connected, such as a B-type or C-type socket. The wiring device 1 is not limited to a 2-digit outlet, and may be a 1-digit or 3-digit outlet, for example.
The wiring device 1 is not limited to the above-described socket, and may be, for example, an information socket to which a connector of a LAN (Local area network) cable can be connected, or a USB (Universal Serial Bus) socket. That is, the wiring device 1 may have the connection unit 11 that can be electrically connected to the electrical equipment a 1. The wiring device 1 may be used to supply electric power from the power supply B1 to the electrical equipment a1 as in the present embodiment, or may be used to connect the electrical equipment a1 to the network N1.
The communication method between the wiring device 1 and the receiving device 3 is not limited to the specific low-power wireless communication, and may be other wireless communication such as Bluetooth (registered trademark) or Wi-Fi (registered trademark). 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).
In the present embodiment, the receiving device 3 may be a local device used in, for example, an HEMS (Home Energy management system). In the present embodiment, the receiving device 3 and the output device 4 may be constituted by 1 device. For example, the portable terminal 7 may be configured to receive the detection signal from the wiring device 1 as the external device 2 without passing through the receiving device 3. In this case, the communication method between the communication unit 13 of the wiring device 1 and the portable terminal 7 is wireless communication such as Wi-Fi (registered trademark).
In the present embodiment, the portable terminal 7 communicates with the receiving apparatus 3 via the router 6 by Wi-Fi (registered trademark), but the present invention is not limited thereto. For example, the mobile terminal 7 may be configured to communicate with the receiving apparatus 3 not via the receiving apparatus 3 but via the network N1. In this case, the mobile terminal 7 is connected to the network N1 via a mobile telephone network (carrier network) provided by a carrier. Examples of the mobile telephone network include a 3G (third generation) line, an LTE (Long term evolution) line, and the like. The portable terminal 7 may be connected to the network N1 via a public wireless LAN.
In the present embodiment, the server 8 may have a function of transmitting a signal to the wiring harness 1. For example, the server 8 may have a function of transmitting a signal for performing survival detection (Alive check) to the wiring fixture 1, a signal for inquiring about the state of the wiring fixture 1, a signal for controlling the processing unit 14 of the wiring fixture 1, or the like.
The wiring device system 100 of the present embodiment includes the audio interface 5, the portable terminal 7, and the server 8 as the output device 4, but the present invention is not limited thereto. For example, the wiring device system 100 may include at least 1 device of the audio interface 5, the mobile terminal 7, and the server 8.
