(1) Overview The wiring device system 300 according to the present embodiment includes a wiring device 10 as shown in FIG. The wiring device 10 is, for example, an outlet (also referred to as an outlet) that is connected to an insertion plug 91 of an electric device and supplies electric power to the electric device. The wiring device 10 is installed in, for example, a building (a housing facility such as a detached house or an apartment house, or a non-housing facility such as an office, a store, a school, or a nursing facility). The wiring device 10 is attached to a construction surface 150 (see FIG. 2A) such as a wall surface, a ceiling surface, and a floor surface of a facility (building), for example.

  As shown in FIG. 1, the wiring device 10 includes a terminal member 2, a connection member 3, a temperature detection unit 5, an opening / closing unit 6, a light emitting unit 82, and a modulation unit 83 (transmission control unit).

  The terminal member 2 is a member to which an external power supply line 92 is electrically connected. The connection member 3 is a member to which the plug 91 is electrically connected. The terminal member 2 and the connection member 3 are connected via a power feeding path 9. That is, external power (for example, AC power) is input to the terminal member 2 through the power supply line 92, and the input power is supplied to the plug 91 connected to the connection member 3 through the power supply path 9.

  The temperature detection unit 5 (detection unit) detects the temperature (physical quantity) of at least one of the terminal member 2 and the connection member 3 as a detection temperature. The opening / closing part 6 is connected to a power supply path 9 between the terminal member 2 and the connection member 3, and interrupts or conducts the power supply path 9. Here, the opening / closing unit 6 switches from the conductive state to the cut-off state when the determination condition is satisfied. The determination condition includes that the temperature detected by the temperature detector 5 is equal to or higher than a threshold temperature (also referred to as a cutoff temperature). The opening / closing part 6 can be switched from the cut-off state to the conductive state when the determination condition is not satisfied.

  The phrase “can be switched from the cut-off state to the conductive state” in the present disclosure means a state in which switching of the opening / closing unit 6 from the cut-off state to the conductive state is permitted. For this reason, unless it is “switchable from the cut-off state to the conductive state”, the switching unit 6 in the cut-off state is prohibited from switching to the conductive state and maintains the cut-off state. Here, the switching of the opening / closing part 6 from the cut-off state to the conductive state may be performed manually by the user, for example, receiving a recovery signal from the outside of the wiring device 10 or a predetermined time elapses. If the restoration condition is satisfied, the wiring device 10 may automatically perform the restoration.

  The light emitting unit 82 is a portion that outputs visible light (a portion that emits light), and is a display lamp that displays the state (normal state or abnormal state) of the wiring device 10 according to the lighting state (lighting, extinguishing or blinking). The modulation unit 83 modulates light output from the light emitting unit 82 (hereinafter, referred to as light emission light), and transmits the internal information of the wiring device 10 from the light emitting unit 82 as an optical signal. That is, the light emitting unit 82 has both a function as an indicator lamp for notifying the state of the wiring device 10 and a function as a light emitting unit for optical communication. The internal information transmitted as an optical signal from the light emitting unit 82 may include, for example, information generated by the control unit 7 described later or a state stored in the storage unit 85 described later. Moreover, the normal state of the wiring device 10 is a state in which the opening / closing part 6 is in a conductive state. The abnormal state is a state in which the opening / closing part 6 is in a cut-off state. The internal information includes information related to the detected temperature (physical quantity) detected by the temperature detection unit 5 (detection unit).

  According to the above configuration, when the temperature detected by the temperature detection unit 5 is equal to or higher than the threshold temperature and the determination condition is satisfied, the wiring device 10 switches the opening / closing unit 6 from the conduction state to the cutoff state. As a result, the terminal member 2 and the connection member 3 are electrically disconnected. Therefore, if the detected temperature may rise due to, for example, poor contact between the terminal member 2 and the power supply line 92 or poor contact between the connection member 3 and the plug 91, the wiring device 10 automatically, The connecting member 3 can be electrically disconnected from the terminal member 2. Thereby, for example, even when the plug 91 of the electric device is still connected to the connection member 3, the power supply to the electric device is stopped, and further heat generation can be suppressed.

  Further, when the opening / closing part 6 is switched from the conductive state to the cut-off state, the user is notified of the occurrence of an abnormality in the wiring device 10 in the lighting state of the light emitting part 82 as an indicator lamp. Thereby, the user can quickly know the occurrence of the abnormality. Also, the modulation unit 83 modulates the light emitted from the light emitting unit 82 and transmits the internal information of the wiring device 10 from the light emitting unit 82 as an optical signal. By receiving the optical signal from the wiring device 10 by the receiving device 100, the user can easily obtain the internal information of the wiring device 10 when an abnormality occurs.

  That is, since the wiring device 10 outputs the internal information to the outside as an optical signal, more information can be output to the outside than when the state of the wiring device 10 is notified when the light emitting unit 82 is turned on. As a result, when an abnormality occurs in the wiring device 10, the cause of the abnormality can be easily clarified by using information output from the wiring device 10 as an optical signal to the outside. Moreover, information can be easily acquired from the wiring device 10 by receiving the optical signal with the receiving device 100. For this reason, the cause of the abnormality can be clarified by using only the information acquired from the wiring device 10 without bringing the wiring device 10 into a service center, for example.

  Further, since the wiring device 10 outputs internal information to the outside as an optical signal, when the wiring device 10 includes an indicator lamp and a microcomputer (hereinafter referred to as “microcomputer”), it is only necessary to change the operation setting of the microcomputer. The indicator lamp can be used as the light emitting unit 82 for optical communication. As a result, the wiring device 10 can be configured at a low price. Furthermore, as the receiving device 100, an existing terminal device (for example, a smartphone, a mobile phone, a tablet, or a PC (Personal Computer)) having an optical communication function can be used. As a result, the receiving apparatus 100 can also be configured at a low price.

(2) Details Next, the wiring device system 300 according to the present embodiment will be described in more detail.

The receiving device 100 is a device that receives information output from the wiring device 10 as an optical signal. The server 200 is a device that creates a database of information output from the wiring device 10 as an optical signal.

In addition to this, the wiring device 10 further includes a housing 4 (see FIG. 2A), a control unit 7, an operation member 81, a switch 84, a storage unit 85, a power supply circuit 86, and a cutoff circuit 87.

  As shown in FIGS. 2A and 2B, the wiring device 10 (that is, the outlet) is an embedded wiring arranged so as to be fitted in an opening (not shown) provided in a construction surface 150 such as a wall surface of a building. It is an instrument. The wiring device 10 has an annular decorative plate 43. In a state where the wiring device 10 is installed on the construction surface 150, the decorative plate 43 is disposed on the construction surface 150, and the front surface of the housing 4 of the wiring device 10 is exposed from the inside of the decorative plate 43. In the present embodiment, the case where the wiring device 10 is for indoor use, that is, the case where the construction surface 150 is the inner wall surface of a building (facility) will be described. However, the present invention is not limited to this example, and the wiring device 10 is for outdoor use. Also good.

  In the following, with the wiring device 10 attached to the inner wall surface of the building, which is the construction surface 150, when the wiring device 10 is viewed from the front, the upper direction (vertical direction) is defined as “upward” and the lower direction (vertical direction) as “ In the following description, it is assumed that “downward”, the right side is “right”, and the left side is “left”. Furthermore, the direction orthogonal to the construction surface 150 is referred to as “front-rear direction”, the front side of the construction surface 150 is referred to as “front”, and the back side is described as “rear”. However, these directions are not intended to limit the use direction of the wiring device 10. For example, when the wiring device 10 is attached to a floor surface instead of a wall surface, the “front-rear direction” is a direction perpendicular to the floor surface, and the “up-down direction” and the “left-right direction” are directions parallel to the floor surface. Become.

  In the present embodiment, as the wiring device 10, a two-port type outlet capable of simultaneously connecting two plugs 91 is illustrated. That is, the wiring device 10 has a plurality (two in the illustrated example) of connection ports 11 so as to correspond to a plurality (two in the illustrated example) of the plugs 91. Each of the plurality of connection ports 11 is configured to be able to connect one insertion plug 91, and is arranged side by side along the vertical direction on the front surface of the housing 4.

  Of the two connection ports 11, one (upper) connection port 11 is an outlet with a two-pole grounding electrode for AC 100V. The other (lower) connection port 11 is a two-pole outlet without a ground electrode for AC 100V. In other words, in the present embodiment, the plug plug 91 is a two-pole plug having a pair of plug blades 911 (conductors). Therefore, each connection port 11 has a pair of insertion holes 111. Each of the pair of insertion holes 111 is a hole into which each of the pair of plug blades 911 of the insertion plug 91 is inserted. The pair of insertion holes 111 are provided side by side in the left-right direction.

  In addition, the wiring device 10 includes a pair of terminal members 2 having different polarities so as to correspond to the two-pole plug. The pair of terminal members 2 are portions to which a pair of external power supply lines 92 are electrically connected, and are formed of a conductive metal (such as copper or a copper alloy). Of the pair of terminal members 2, one terminal member 2 is connected to the L pole (HOT) side feed line 92 of the pair of feed lines 92, and the other terminal member 2 is connected to the N pole (COLD). ) Side feed line 92 is connected.

  Similarly, the wiring device 10 includes a pair of connection members 3 having different polarities for each connection port 11, and includes a total of two pairs (four) of connection members 3. The pair of connecting members 3 are members that are electrically connected to the pair of plug blades 911 of the plug 91 and are formed of a metal having conductivity and elasticity (for example, copper or copper alloy). Each of the pair of connection members 3 corresponds to each of the pair of insertion holes 111 of the connection port 11 on a one-to-one basis, is disposed on the back side of the corresponding insertion hole 111, and is plugged into the corresponding insertion hole 111. It is electrically connected to the blade 911. Each connecting member 3 has a pair of blade receiving pieces facing each other, and is electrically connected to the plug blade 911 by sandwiching the plug blade 911 between the pair of blade receiving pieces.

  Of the two pairs (four) of connecting members 3, two connecting members 3 having the same polarity are connected to each other by a lead plate 30 (see FIG. 1). Further, the connection member 3 and the terminal member 2 having the same polarity are electrically connected via the opening / closing part 6 and the power supply path 9.

  The housing 4 includes the various components described above (that is, the terminal member 2, the connection member 3, the temperature detection unit 5, the opening / closing unit 6, the light emitting unit 82, the modulation unit 83, the control unit 7, the operation member 81, the switch 84, and the power supply circuit. 86, a blocking circuit 87, and a storage unit 85). The housing 4 has an outer cover 42 and an outer body (not shown). The outer cover 42 is formed in a substantially rectangular flat plate shape, for example, and the outer body is formed in a substantially rectangular parallelepiped box shape, for example. The casing 4 is configured by combining the outer cover 42 and the outer body. The housing 4 is made of a synthetic resin having electrical insulation. The outer cover 42 is disposed on the construction surface 150 (that is, a wall surface), and the outer body is embedded in the wall.

  In the outer cover 42, the two connection ports 11 described above are formed. The two connection ports 11 are formed, for example, side by side in the vertical direction in the upper center of the outer cover 42 and in the rightward range. As described above, each of the pair of connection members 3 is disposed on the back side of the outer cover 42 at a position corresponding to each connection port 11.

  The outer cover 42 is provided with two display holes 821a and 822a and two operation holes 84a and 421 penetrating in the front-rear direction. Each of the display holes 821a and 822a is a hole in which a later-described first light emitting unit 821 and second light emitting unit 822 of the light emitting unit 82 are disposed. The display holes 821a and 822a are circular holes, for example, and are provided side by side in the left-right direction at the upper left portion of the outer cover 42. The operation hole 84a is a hole in which the switch 84 is disposed. The operation hole 84a is, for example, a circular hole and is provided below the display holes 821a and 822a in the outer cover 42. The operation hole 421 is a hole in which the operation member 81 is disposed. The operation hole 421 is, for example, a vertically long rectangular hole, and is provided below the operation hole 84a.

  The light emitting unit 82 is an indicator lamp that emits visible light (for example, light having a wavelength of 400 nm to 700 nm), and the state of the wiring fixture 10 is a combination of the lighting state (lit, flashing, and extinguished) of the light emitting unit 82 and the emission color. To inform. In this embodiment, although the light emission part 82 alert | reports the state of the wiring fixture 10 by the combination of a lighting state and luminescent color, you may alert | report only by a lighting state. The state of the wiring device 10 is either a normal state or an abnormal state of the wiring device 10. The normal state of the wiring device 10 is, for example, a conduction state in which the opening / closing unit 6 is conductive, and the abnormal state of the wiring device 10 is, for example, a blocking state in which the opening / closing unit 6 is blocked.

  The light emitting unit 82 includes two light emitting units (a first light emitting unit 821 and a second light emitting unit 822) that emit visible light. The 1st light emission part 821 and the 2nd light emission part 822 are comprised by the light emitting element (For example, LED (Light Emitting Diode)) from which luminescent color differs mutually. The emission color of the first light emitting unit 821 is, for example, green, and the emission color of the second light emitting unit 822 is, for example, red.

  When the wiring device 10 is in a normal state, the first light emitting unit 821 is turned on and the second light emitting unit 822 is turned off. In this lighting state, the normal state of the wiring device 10 is notified. In the abnormal state of the wiring device 10, the first light emitting unit 821 is turned off and the second light emitting unit is turned on. In this lighting state, the abnormal state of the wiring device 10 is notified.

  As described above, the first light emitting unit 821 and the second light emitting unit 822 are disposed in the display holes 821a and 822a of the outer cover 42, respectively. Thereby, each light emission of the 1st light emission part 821 and the 2nd light emission part 822 is visually recognizable from the front of the housing | casing 4 through each display hole 821a and 822a.

  The switch 84 is a manual switch (test switch) for forcibly switching the opening / closing part 6 from the conductive state to the cutoff state, and is, for example, a push button type switch. The switch 84 is turned on when the push operation is performed, and is turned off when the push operation is released. The switch 84 outputs a signal indicating the on state to the control unit 7 in the on state, and outputs a signal 7 indicating the off state to the control unit in the off state. As described above, the switch 84 is disposed in the operation hole 42 a of the outer cover 42, whereby the switch 84 can be operated from the front of the housing 4.

  The operation member 81 is an operation member for manually switching the opening / closing part 6 from the shut-off state to the conductive state. The operation member 81 is, for example, a lever type handle that can rotate in the vertical direction. As described above, the operation member 81 is disposed in the operation hole 421 of the cover, so that the operation member 81 can be operated from the front of the housing 4.

  The operation member 81 rotates in conjunction with the opening / closing part 6 and moves between an on position (see FIG. 2A) and an off position (see FIG. 2B). The on position is a position corresponding to the conduction state of the opening / closing part 6, and the off position is a position corresponding to the blocking state of the opening / closing part 6. That is, if the opening / closing part 6 is in a conductive state, the operation member 81 is located at the on position as shown in FIG. 2A. When the operation member 81 is in the on position, the front surface of the operation member 81 is substantially flush with the front surface of the housing 4. On the other hand, when the opening / closing part 6 is switched from the conductive state to the cut-off state, the operation member 81 rotates and the front end of the operation member 81 moves forward (front side), and the operation member 81 is turned off as shown in FIG. 2B. Move to position. When the operation member 81 is in the off position, the operation member 81 projects forward from the front surface of the housing 4.

  Thus, the operation member 81 and the opening / closing part 6 are interlocked with each other. For this reason, when the opening / closing part 6 receives a drive signal from the interruption circuit 87 as described later and switches from the conductive state to the cutoff state, the operation member 81 moves from the on position to the off position. On the contrary, when the operation member 81 moves from the off position to the on position, the opening / closing part 6 is switched from the blocking state to the conducting state. Therefore, when the user operates the operating member 81 in the off position and moves it to the on position, the open / close section 6 in the shut-off state can be switched to the conductive state.

  The opening / closing unit 6 switches from the conductive state to the cutoff state not only when the drive signal is received from the cutoff circuit 87 but also when the operation member 81 is manually moved from the on position to the off position. Therefore, the opening / closing part 6 also functions as an operation switch that is turned on / off in response to an operation of the operation member 81.

  As shown in FIG. 1, the temperature detection unit 5 (detection unit) detects both temperatures (physical quantities) of the terminal member 2 and the connection member 3 as detection temperatures. In addition, although the temperature detection part 5 of this embodiment detects the temperature of both the terminal member 2 and the connection member 3, the temperature detection part 5 detects the temperature of at least one of the terminal member 2 and the connection member 3. do it. The temperature detection unit 5 includes a first temperature sensor 51 and a second temperature sensor 52. The first temperature sensor 51 is a sensor that detects the temperature of the terminal member 2. The second temperature sensor 52 is a sensor that detects the temperature of the connection member 3. The first temperature sensor 51 is thermally coupled to the terminal member 2, and the second temperature sensor 52 is thermally coupled to the connection member 3. Each of the first temperature sensor 51 and the second temperature sensor 52 is realized by, for example, a thermistor, a thermocouple, a bimetal, or a thermopile.

  The temperature detection unit 5 outputs a detection signal corresponding to the detected temperature detected by the first temperature sensor 51 and the second temperature sensor 52 to the control unit 7. The “detection signal” referred to in the present disclosure may be a signal (electric signal) that conveys information according to temperature by a specific code. For example, an electrical quantity such as a resistance value, a voltage value, or a current value according to temperature. Is a signal that changes. In addition, the detection signal may be a signal that switches between ON / OFF (or high level / low level) binary values depending on whether the temperature detected by the temperature detection unit 5 is equal to or higher than the threshold temperature or lower than the threshold temperature. Furthermore, the temperature detection unit 5 may include a processing circuit that processes the outputs of the first temperature sensor 51 and the second temperature sensor 52 and outputs a detection signal.

  A pair of first temperature sensors 51 are provided so as to correspond to the pair of terminal members 2 having different polarities. The second temperature sensor 52 is thermally coupled to, for example, the lead plate 30 that connects the connecting members 3 having the same polarity, and detects the temperature of the connecting member 3 by detecting the temperature of the lead plate 30. In this case, a pair of second temperature sensors 52 are provided so as to correspond to a pair of lead plates 30 having different polarities.

  Furthermore, when the temperature of the connection member 3 rises, the temperature of the internal space of the housing 4 also rises due to heat radiation from the connection member 3 or the lead plate 30. Similarly, when the temperature of the terminal member 2 rises, the temperature of the internal space of the housing 4 also rises due to the heat radiation of the terminal member 2. Therefore, the temperature detection unit 5 detects the temperature of the detection point or the like set in the internal space of the housing 4 instead of on the connection member 3, the lead plate 30, or the terminal member 2, so that the connection member 3 indirectly. Alternatively, the temperature of the terminal member 2 may be detected.

  The opening / closing part 6 is a device that conducts or blocks the power supply path 9 between the terminal member 2 and the connection member 3. If the opening / closing part 6 is in a conducting state, the terminal member 2 and the connecting member 3 are electrically connected via the opening / closing part 6, and if the opening / closing part 6 is in a shut-off state, the terminal member 2 and the connecting member 3 are connected. The gap is electrically cut off (insulated) by the opening / closing part 6. The wiring device 10 includes a pair of terminal members 2 having different polarities, and the opening / closing part 6 is electrically connected to both of the pair of terminal members 2. Therefore, if the opening / closing part 6 is in a cut-off state, the two pairs (four pieces) of the connection members 3 are all electrically disconnected from the terminal member 2.

  More specifically, the opening / closing part 6 is, for example, a breaker, and includes a pair of contact devices having different polarities and an electromagnetic release device. Each of the pair of contact devices has a fixed contact and a movable contact. The movable contact moves between a closed position in contact with the fixed contact and an open position away from the fixed contact. The connection member 3 is electrically connected to the fixed contact, and the terminal member 2 is electrically connected to the movable contact. In the steady state, the opening / closing part 6 having such a configuration is in a conductive state in which the movable contact is located at the closed position so that the terminal member 2 and the connection member 3 are electrically connected. On the other hand, when the opening / closing part 6 receives the drive signal from the interruption circuit 87, it drives the electromagnetic release device and moves the movable contact to the open position, thereby electrically connecting the terminal member 2 and the connection member 3 to each other. Switch to the shut-off state to shut off. As described above, the opening / closing unit 6 is switched from the conductive state to the cut-off state by the drive signal from the cut-off circuit 87.

  Further, as described above, the operation member 81 is mechanically coupled to the opening / closing unit 6, and can be switched to a cut-off state or a conduction state by the operation of the operation member 81.

  The modulation unit 83 modulates the light emitted from the light emitting unit 82 based on the output signal from the control unit 7, thereby transmitting the output signal from the control unit 7 as an optical signal from the light emitting unit 82 (that is, the transmission control unit). ). That is, the modulation unit 83 modulates any one or more of the amplitude (intensity), frequency, and phase of the emitted light of the light emitting unit 82 based on the output signal from the control unit 7 using a preset modulation method. Thus, the output signal from the control unit 7 is superimposed on the light emitted from the light emitting unit 82. Thereby, the output signal from the control unit 7 is transmitted from the light emitting unit 82 as an optical signal.

  In the present embodiment, a binary light intensity modulation method that expresses an optical signal as binary values of lighting and blinking of the light emitting unit 82 is employed as the modulation method. That is, the modulation unit 83 turns on or off the light emitting unit 82 according to the codes “1” and “0” included in the signal from the control unit 7. Thereby, the light emission part 82 blinks with the blink pattern according to the signal from the control part 7. FIG. By this blinking, a signal from the control unit 7 is transmitted from the light emitting unit 82 as an optical signal.

  In this embodiment, binary light intensity modulation is adopted as a modulation method, but multi-value light intensity modulation that expresses an optical signal with multiple values by changing the intensity of light emitted from the light-emitting unit 82 in three or more stages. May be adopted. Further, for example, amplitude shift keying, phase shift keying, frequency shift keying, or quadrature shift keying may be employed as the modulation method. As described above, when the binary light intensity modulation method (or the multi-value light intensity modulation method) is adopted as the modulation method, the driving of the light emitting unit 82 can be realized with a simple configuration using a switching element. 83 can be realized with an inexpensive configuration.

  Information (hereinafter referred to as first information) transmitted from the light emitting unit 82 as an optical signal is, for example, detailed information on the internal state of the wiring device 10, for example, information indicating an operation history of the wiring device 10. It is. The operation history of the wiring device 10 includes an operation history of the opening / closing unit 6, a detected temperature transition of the temperature detection unit 5, and analysis result information. The analysis result information is information indicating a result of analyzing the operation history of the opening / closing unit 6 and the detected temperature transition of the temperature detection unit 5 (physical quantity detected by the detection unit). Information (hereinafter, referred to as second information) notified (output) by the light emitting unit 82 as an indicator lamp is information indicating the state of the wiring device 10 as described above.

  Therefore, the first information and the second information are information related to each other in that they are related to the wiring device 10, for example. The first information includes information different from the second information (for example, an operation history of the opening / closing unit 6, a detected temperature transition of the temperature detecting unit 5, and analysis result information). Further, the second information includes only information indicating the state of the wiring device 10, for example, but the first information includes the operation history of the opening / closing unit 6, the detected temperature transition of the temperature detecting unit 5, and the analysis result information. The first information is more than the second information.

  For this reason, when the cause of the abnormality of the wiring device 10 is specified, if the information (second information) provided by the light emitting unit 82 as the indicator lamp is not sufficient, the first light signal from the light emitting unit 82 is used. By acquiring the information, the cause of the abnormality of the wiring device 10 can be specified more accurately.

  The modulation unit 83 also functions as a drive circuit that drives the light emitting unit 82 to turn on or blink the light emitting unit 82 in accordance with an output signal from the control unit 7. That is, when the light emitting unit 82 is turned on or blinked, the control unit 7 outputs a signal for turning on or blinking the light emitting unit 82 to the modulation unit 83.

  In the present embodiment, the light emitting unit 82 serves both as an indicator lamp that notifies the state of the wiring device 10 and a light emitting unit for optical communication. The modulation unit 83 transmits an optical signal from the light emitting unit 82 while the light emitting unit 82 as an indicator lamp is turned on. The modulation unit 83 blinks the light emitting unit 82 when transmitting an optical signal from the light emitting unit 82, and the blinking seems to make the lighting state of the light emitting unit 82 as an indicator light substantially light. To be done at high speed. Thereby, even if an optical signal is transmitted from the light emitting unit 82 when the light emitting unit 82 functions as an indicator lamp, the optical signal is transmitted without affecting the lighting state of the light emitting unit 82 as the indicator lamp. The

  In the present embodiment, the optical signal is transmitted from the light emitting unit 82 by serial communication. For this reason, when the serial communication code “0” continues, the light-emitting unit 82 as an indicator lamp is turned off. Therefore, when the optical signal is transmitted from the light emitting unit 82, the modulating unit 83 causes the light emitting unit 82 to blink so that it appears to be substantially lit as an indicator lamp. Specifically, for example, the modulation unit 83 modulates the emitted light of the light emitting unit 82 so that the serial communication code “0” does not continue a predetermined number or more.

  The storage unit 85 is a non-volatile storage device (for example, flash memory, SSD (solid state drive)), and stores, for example, internal information of the wiring device 10 (for example, an operation history of the wiring device 10). As described above, the operation history of the wiring device 10 includes, for example, the operation history of the opening / closing unit 6, information on the detected temperature transition of the temperature detection unit 5, and analysis result information.

  Information on the operation history of the opening / closing unit 6 includes information on the time when the opening / closing unit 6 switches from the conducting state to the blocking state (blocking time), and the time when the opening / closing unit 6 switches from the blocking state to the conducting state (conduction). Time) information. The detected temperature transition information includes time transition information of the detected temperature in a certain period including a period from when the detected temperature becomes equal to or higher than the threshold temperature to below the threshold temperature. The threshold temperature is an internal temperature of the wiring device 10 (for example, the temperature of the connection member 3 or the terminal member 2) and is a threshold temperature at which the opening / closing part 6 is blocked. The analysis result information is information obtained by analyzing the operation history of the opening / closing unit 6 and the detected temperature transition of the temperature detection unit 5. The analysis result information includes the presence / absence of occurrence of abnormal overheating above the threshold temperature, the location of occurrence of abnormal overheating, information on whether the switching unit 6 is blocked, graph information that graphs the operation history of the switching unit 6, and a temperature detection unit. 5 includes information such as graph information obtained by graphing the detected temperature transition. In the present embodiment, the location where the abnormal overheating occurs is, for example, one of the four connection members 3 and the two terminal members 2 that are detection targets of the temperature detection unit 5. The analysis result information is information that can be displayed on the display unit 103 of the receiving apparatus 100 for each information of the operation history of the opening / closing unit 6 and the detected temperature transition of the temperature detecting unit 5, and is visualized so that the user can easily grasp it. Information.

  The power supply circuit 86 is a power supply circuit that supplies DC power for operating the wiring device 10. The power supply circuit 86 converts part of the AC power input to the terminal member 2 into DC power, and converts the converted DC power into an electric circuit (the temperature detection unit 5, the control unit 7, the light emitting unit 82, The modulation unit 83, the storage unit 85, and the cutoff circuit 87) are supplied. The power supply circuit 86 is branched and connected to the power supply path 9, and a part of AC power is branched and input from the power supply path 9, and the input AC power is converted into DC power.

  The shut-off circuit 87 is a circuit that allows the open / close unit 6 to be turned on or off in accordance with a control signal from the control unit 7. When receiving the control signal from the control unit 7, the cutoff circuit 87 outputs a drive signal to the opening / closing unit 6. The drive signal is a signal for conducting or blocking the opening / closing unit 6. The opening / closing unit 6 is turned on or off according to the drive signal from the cutoff circuit 87.

  The control unit 7 controls the modulation unit 83 and the cutoff circuit 87 based on the detected temperature of the temperature detection unit 5 and the on / off state of the switch 84. Further, the control unit 7 generates information on the operation history of the wiring device 10 and stores it in the storage unit 85. The control unit 7 is electrically connected to the temperature detection unit 5, the storage unit 85, the switch 84, the modulation unit 83, and the cutoff circuit 87.

  The control unit 7 includes, for example, a microcomputer as a main configuration. The microcomputer realizes a function as the control unit 7 by executing a program recorded in the memory of the microcomputer by a CPU (Central Processing Unit). The program may be recorded in advance in the memory of the microcomputer, may be provided by being recorded in a non-transitory recording medium such as a memory card, or may be provided through an electric communication line. The program is a program for causing the microcomputer to function as the control unit 7.

  The control unit 7 generates information on the transition of the detected temperature of the temperature detection unit 5 and information on the operation history of the opening / closing unit 6 as information on the operation history of the wiring device 10 and stores the information in the storage unit 85. More specifically, the control unit 7 has a clock function that keeps time. And the control part 7 acquires the detection temperature from the temperature detection part 5 for every fixed time, and produces | generates the information which matched the acquired detection temperature and the detection time of the detection temperature whenever it acquires a detection temperature. To be stored in the storage unit 85. The detection time may be substituted with the acquisition time when the control unit 7 acquires the detected temperature from the temperature detection unit 5. Information on the transition of the detected temperature of the temperature detecting unit 5 is formed by the information generated in this way. Moreover, whenever the control part 7 controls the interruption | blocking circuit 87 and makes the opening-and-closing part 6 conduct | electrically_connect or interrupts | blocks, it produces | generates the information of the time (conduction time) which made it conduct, or the time (interruption time) which made it shut off. Save in the storage unit 85. Information of the operation history of the opening / closing unit 6 is formed by the information generated in this way.

  The control unit 7 controls the cutoff circuit 87 to cut off and conduct the switching unit 6 according to whether a determination condition including that the temperature detected by the temperature detection unit 5 is equal to or higher than the threshold temperature is satisfied. To control. More specifically, the control unit 7 receives the detection signal from the temperature detection unit 5 to acquire the detected temperature. And the control part 7 compares the threshold temperature (cutoff temperature) memorize | stored in memory etc. with the acquired detected temperature, and determines determination conditions.

  In this embodiment, as an example, the determination condition is only that the temperature detected by the temperature detection unit 5 is equal to or higher than the threshold temperature. That is, the control unit 7 determines that the determination condition is satisfied if the detected temperature of any of the four connection members 3 and the two terminal members 2 satisfies the determination condition. The control unit 7 determines that the determination condition is not satisfied unless all the detected temperatures of the four connection members 3 and the two terminal members 2 satisfy the determination condition.

  When the control unit 7 determines that the determination condition is satisfied, the control unit 7 outputs a control signal to the cutoff circuit 87 to switch the open / close unit 6 from the conductive state to the cutoff state. Moreover, when it determines with the determination conditions not being satisfy | filled, the control part 7 outputs a control signal to the interruption | blocking circuit 87, for example, enables the switching part 6 to be switched from a interruption | blocking state to a conduction | electrical_connection state. Thereby, by operating the operation member 81, the opening / closing part 6 can be switched from the cutoff state to the conductive state. Instead of switching the switching unit 6 from the shut-off state to the conducting state by operating the operation member 81, the opening / closing unit 6 may be switched from the blocking state to the conducting state by a control signal of the shut-off circuit 87.

  When the opening / closing unit 6 is switched from the conduction state to the cutoff state, the control unit 7 analyzes the operation history of the wiring device 10 stored in the storage unit 85 at the time of the cutoff time, for example, and creates analysis result information (that is, Generated). And the control part 7 preserve | saves the produced analysis result information in the memory | storage part 85 as an operation | movement log | history of the wiring instrument 10, and outputs it to the modulation | alteration part 83 as mentioned later, and transmits from the light emission part 82 as an optical signal. .

  The control unit 7 controls the modulation unit 83 to drive the light emitting unit 82 according to the conduction state or the cutoff state of the opening / closing unit 6. Thereby, as described above, the state (normal state or abnormal state) of the wiring device 10 is notified by the combination of the lighting state of the light emitting unit 82 as the indicator lamp and the light emission color. That is, when the opening / closing unit 6 is in a conductive state, the control unit 7 outputs a signal to the modulation unit 83 to turn on the first light emitting unit 821 and turn off the second light emitting unit 822. Thereby, the normal state of the wiring apparatus 10 is alert | reported by the light emission part 82 as an indicator lamp. In addition, when the opening / closing unit 6 is in the shut-off state, the control unit 7 outputs a signal to the modulation unit 83 to turn off the first light emitting unit 821 and turn on the second light emitting unit 822. Thereby, the abnormal state of the wiring apparatus 10 is alert | reported by the light emission part 82 as an indicator lamp.

  The control unit 7 controls the modulation unit 83 while notifying the abnormal state of the wiring device 10 in the lighting state of the light emitting unit 82, and stores the operation history information of the wiring device 10 stored in the storage unit 85. The light emitting unit 82 (second light emitting unit 822) is transmitted as an optical signal. Thereby, the abnormal state of the wiring device 10 is notified in the lighting state as the indicator light of the light emitting unit 82, and at the same time, information on the operation history of the wiring device 10 (that is, the wiring device 10) by the optical signal transmitted from the light emitting unit 82. Detailed information on the internal state of the data is output to the outside.

  The optical signal transmitted from the light emitting unit 82 of the wiring device 10 can be received by the receiving device 100 possessed by the user (or serviceman). The receiving device 100 can display the received operation history information of the wiring device 10 on the display unit 103.

The program is a program for causing the microcomputer to function as the control unit 203.

(2.4) Operation Description Next, the operation of the wiring device system 300 will be described with reference to FIG.

  When abnormal overheating (that is, a temperature equal to or higher than the threshold temperature) has not occurred in all of the four connection members 3 and the two terminal members 2 of the wiring device 10, the temperature detected by the temperature detector 5 is less than the threshold temperature. is there. For this reason, the control unit 7 determines that the determination condition is not satisfied (that is, the wiring device 10 is in a normal state). And the control part 7 controls the interruption | blocking circuit 87, when the wiring instrument 10 is a normal state, and makes the opening-and-closing part 6 a conduction state (S1).

  Further, when the wiring device 10 is in a normal state, the control unit 7 controls the modulation unit 83 to turn on the first light emitting unit 821 of the light emitting unit 82 and turn off the second light emitting unit 822 (S2). Thereby, it is alert | reported that the wiring instrument 10 is a normal state by the lighting state of the light emission part 82 as an indicator lamp. The control unit 7 generates information on the operation history of the wiring device 10 (that is, the detected temperature transition of the temperature detection unit 5 and the operation history of the opening / closing unit 6) while the wiring device 10 is in a normal state, and stores the information. 85.

  And when abnormal overheating (namely, temperature more than threshold temperature) generate | occur | produces in either of the four connection members 3 and the two terminal members 2 of the wiring instrument 10 (S3), the temperature detection part 5 will detect the abnormal overheating. Then, the control unit 7 determines that the determination condition is satisfied based on the temperature detected by the temperature detection unit 5. When determining that the determination condition is satisfied, the control unit 7 controls the blocking circuit 87 to block the opening / closing unit 6 (S4).

  And the control part 7 will analyze the operation | movement history (The detection temperature transition of the temperature detection part 5, and the operation | movement history of the switching part 6) preserve | saved at the memory | storage part 85, if the opening / closing part 6 is interrupted | blocked. Analysis result information is created (that is, generated) (S5). Then, the control unit 7 stores the created analysis result information in the storage unit 85 as an operation history of the wiring device 20.

  Then, the control unit 7 controls the modulation unit 83 to turn off the first light emitting unit 821 of the light emitting unit 82 and turn on the second light emitting unit 822 (S6). At that time, the control unit 7 outputs the operation history information of the wiring device 10 stored in the storage unit 85 to the modulation unit 83. Accordingly, the modulation unit 83 modulates the light emission of the second light emitting unit 822 based on the operation history information from the control unit 7, thereby obtaining the operation history information from the control unit 7 from the second light emitting unit 822. It transmits as an optical signal (S6). That is, an optical signal is transmitted from the second light emitting unit 822 while the second light emitting unit 822 as the indicator lamp is lit. In other words, information on the operation history of the wiring device 10 is transmitted as an optical signal from the second light emitting unit 822 while the second light emitting unit 822 is reporting the abnormal state of the wiring device 10.

  Then, the user (or serviceman) receives the optical signal transmitted from the light emitting unit 82 of the wiring device 10 by the light receiving unit 101 of the receiving device 100 (S7). The receiving device 100 acquires information on the operation history of the wiring device 10 by demodulating the optical signal received by the light receiving unit 101 by the demodulating unit 102. Then, the receiving device 100 activates the display-only application and displays the analysis result information included in the operation history of the wiring device 10 on the display unit 103 as illustrated in FIG. 4 (S8). As described above, the receiving device 100 does not perform the analysis process of the operation history of the wiring device 10 and only displays the analysis result information created by the wiring device 10, so that the details of the internal state of the wiring device 10 can be obtained without any processing load. Information (analysis result information) can be displayed.

  In the example of FIG. 4, for example, three pieces of information A1, A2, and A3 are displayed on the display unit 103 as analysis result information. The information A1 is information indicating the number of times the opening / closing unit 6 is blocked (for example, twice). The information A2 is information indicating an abnormal location (for example, the connection member 3 on the right side of the upper stage) where the abnormal overheating has occurred. The information A3 is information indicating a graph of the detected temperature transition of the connection member 3 in which abnormal overheating has occurred. With this display, the user can know detailed information on the internal state of the wiring device 10 when an abnormality has occurred. Then, the user can examine the cause of the abnormal state of the wiring device 10 and the countermeasure from this detailed information.

  The user can reuse the wiring device 10 when the cause of the abnormal state of the wiring device 10 is removed. In the case of reusing, the operation member 81 of the wiring device 10 is returned from the off position to the on position, so that the opening / closing part 6 of the wiring device 10 is switched from the cut-off state to the conducting state, and the wiring device 10 can be reused. . Alternatively, for example, the user can remove and replace the wiring device 10 as a countermeasure.

  In addition, the receiving device 100 transmits the received operation history information of the wiring device 10 from the communication unit 104 to the server 200 (S9). When the communication unit 201 receives the operation history information of the wiring device 10 from the receiving device 100 (S10), the server 200 stores the received operation history information of the wiring device 10 in the database 202 (S11). Thereby, the manufacturer of the wiring device 10 can examine the cause of the abnormal state of the wiring device 10, the countermeasure against the abnormality, and the maintenance method of the wiring device 10 based on the database 202.

The above embodiment can be variously modified according to the design and the like as long as the object of the present disclosure can be achieved. Moreover, the function similar to the control part 7 which concerns on the said embodiment is the information output method which outputs information from the wiring instrument 10, the program for making a computer perform said information output method, or the non-recording which recorded said program It may be embodied by a temporary recording medium or the like.

  Hereinafter, modifications of the embodiment will be listed. The modifications described below can be applied in appropriate combinations.

(Modification 1)
In the above embodiment, the second light emitting unit 822 to which the optical signal is transmitted is configured by one light emitting element, but may be configured by a plurality of light emitting elements. In this case, the plurality of light emitting elements constituting the second light emitting unit 822 emit light in synchronization. That is, when turning on, turning off, or blinking a plurality of light emitting elements, the plurality of light emitting elements are turned on, turned off, or blinked simultaneously. Thereby, when using the 2nd light emission part 822 as a light emission part of optical communication, the light quantity of the light emitted from the light emission part of optical communication can be increased, and the light emission area | region of the light emission part of optical communication can be expanded. Thereby, the reception sensation of the optical signal in the receiving apparatus 100 can be improved.

  In the above embodiment, the optical signal is transmitted from the second light emitting unit 822, but the optical signal may be transmitted from the first light emitting unit 821. In this case, similarly to the above, the first light emitting unit 821 may be configured by a plurality of light emitting elements, and the plurality of light emitting elements may be synchronized to emit light. Thereby, also in this case, the reception sensation of the optical signal in the receiving apparatus 100 can be improved.

(Modification 2)
In the above embodiment, the light emitting unit 82 is configured by a light emitting element that emits visible light (for example, light having a wavelength of 400 nm to 700 nm), and the optical signal is transmitted using visible light. Not. For example, the light emitting unit 82 may include a first light emitting element that outputs visible light and a second light emitting element that outputs ultraviolet light (for example, light of 280 nm to 400 nm). In this case, the optical signal is transmitted using both the visible light of the first light emitting element and the infrared light of the second light emitting element. In this case, the optical signal may be transmitted in synchronization with the first light emitting element and the second light emitting element, or may be transmitted without being synchronized. In this case, the light receiving unit 101 of the receiving device 100 is a light receiving unit that can receive both visible light and ultraviolet light. According to this configuration, even in places where it is difficult to reach with visible light such as a shadow, ultraviolet rays can be reflected and reach. For this reason, the optical signal from the wiring device 10 can be more reliably received by the receiving device 100.

(Modification 3)
In said embodiment, the temperature detection part 5 is provided as a detection part, and the temperature detection part 5 detects the temperature of at least one of the connection member 3 and the terminal member 2 as a physical quantity. However, the detected physical quantity is not limited to temperature. The detection unit may detect various physical quantities that can be detected inside the wiring device 10. For example, the detection unit may detect one or more of current, voltage, power, temperature, stress, and vibration as a physical quantity. The current is, for example, a current that flows through the power supply path 9 inside the wiring device 10. The voltage is a voltage of at least one of the connection member 3 and the terminal member 2. The electric power is the electric power that flows through the power supply path 9 of the wiring device 10. The temperature may be, for example, the temperature of the space inside the wiring device 10 or may be the temperature of either the connection member 3 or the terminal member 2. The stress is a stress acting on the wiring device 10. The vibration is a mechanical vibration that acts on the wiring device 10. The vibration may be an electric vibration generated in a circuit inside the wiring device 10 (for example, an electric vibration generated by an external electromagnetic wave). According to this configuration, an appropriate physical quantity can be detected according to the internal configuration of the wiring device 10 or the installation location of the wiring device 10. Thereby, when abnormality occurs in the wiring device 10, the cause of the abnormality can be clarified more accurately.

(Modification 4)
In the above embodiment, the wiring instrument 10 generates analysis result information from the operation history of the opening / closing unit 6 and the detected temperature transition of the temperature detection unit 5, and the analysis result information is transmitted to the receiving device 100 as an optical signal and received. It is displayed on the display unit 103 of the apparatus 100. However, it is not limited to the case where the analysis result information is created by the wiring device 10.

The abnormality content B2 is an abnormality content that informs that the opening / closing part 6 is blocked. The abnormality content B3 is an abnormality content indicating a location where the abnormal overheating has occurred (the upper right connection member 3 in the example diagram). With this display, the user can know the abnormality content of the wiring device 10.

  Then, when the user operates the receiving device 100 to request a countermeasure against the abnormal content of the wiring device 10 (S114), the receiving device 100 communicates information on the abnormal content of the wiring device 10 and a countermeasure request signal. The data is transmitted from the unit 104 to the communication unit 201 of the server 200B (S115).

  Then, the server 200B receives the information of the abnormality content of the wiring device 10 and the countermeasure request signal from the receiving device 100 by the communication unit 201 (S116). Then, the server 200B searches the countermeasure database 205 and identifies a countermeasure for the received abnormal content of the wiring device 10 (S117). Then, the server 200B transmits the identified countermeasure (search result) from the communication unit 201 to the communication unit 104 of the receiving device 100 (S118).

  Then, when the communication unit 104 receives the countermeasure from the server 200 (S119), the receiving apparatus 100 displays the received countermeasure on the display unit 103 as illustrated in FIG. 10B (S120). Then, the process ends.

  In the example of FIG. 10B, for example, two countermeasures C1 and C2 are displayed on the display unit 103 as countermeasures. The countermeasure C <b> 1 is a countermeasure for removing the load device inserted into the connection port 11 of the wiring device 10 from the connection port 11.
