1.1 embodiment 1

1.1.1 summary

Fig. 1 shows a notification system 10 according to the present embodiment. The notification system 10 is provided in, for example, a facility (e.g., a factory) for notifying a person within the facility. The notification system 10 includes a notification device 20. As shown in fig. 2, the notification device 20 includes a slot connection portion 23, a receiving portion 24, and a notification portion 25, and the slot connection portion 23 is physically attached to the wiring slot 40 and electrically connected to the wiring slot 40. The receiving unit 24 is configured to receive a Communication signal S10 (see fig. 1) based on Power Line Communication (Power Line Communication) from the wiring duct 40 via the duct connecting unit 23. The notification unit 25 is configured to perform notification in accordance with the communication signal S10 received by the reception unit 24.

In this way, the notification system 10 can be attached to the wiring duct 40 through the duct connection portion 23. The receiving unit 24 receives the communication signal S10 from the wiring duct 40 via the duct connecting unit 23, and the notification unit 25 notifies the user of the communication signal S10 received by the receiving unit 24. In this way, in the notification system 10, the notification unit 25 can be mounted to the wiring duct 40, and since it is not necessary to directly mount the notification unit 25 to the device apparatus 30 (see fig. 1), the degree of freedom in installation of the notification unit 25 can be improved. Further, since the wiring duct 40 is used as a communication path with the notification unit 25, construction of the communication path with the notification unit 25 can be omitted as compared with a case where a communication path (for example, a LAN cable or the like) provided separately from the wiring duct 40 is used. Further, compared to a case where wireless communication (for example, wireless communication using radio waves as a medium) is used as communication with the notification unit 25, it is possible to reduce the possibility that a communication signal transmitted to the notification unit 25 (reception unit 24) is intercepted or that the notification unit 25 (reception unit 24) fails to receive the communication signal. Therefore, the security and reliability of communication with the notification unit 25 can be improved. In short, according to the notification system 10, it is possible to improve the degree of freedom of the installation of the notification unit 25, to realize the omission of the construction of the path for the communication with the notification unit 25, and to improve the safety and reliability of the communication with the notification unit 25.

1.1.2 Structure

The notification system 10 is described in more detail below with reference to the figures. As shown in fig. 1, the notification system 10 includes an equipment device 30, a wiring duct 40, and a detection device 50 in addition to the notification device 20.

First, the notification device 20 will be explained. Fig. 2 is a block diagram of the circuit configuration of the notification device 20, and fig. 3 is a perspective view of the notification device 20. As shown in fig. 2 and 3, the notification device 20 is composed of an adapter 21 and a main body 22. As shown in fig. 2, the notification device 20 includes a slot connecting portion 23, a receiving portion 24, a notification portion 25, a first power supply terminal portion 26, a first communication terminal portion 27, a second power supply terminal portion 28, and a second communication terminal portion 29.

As shown in fig. 4 and 5, the adapter 21 includes a first housing 210. As shown in fig. 2, the first housing 210 is provided with a slotted connection portion 23, a receiving portion 24, a first power supply terminal portion 26, and a first communication terminal portion 27.

The first housing 210 is hollow cylindrical (right circular cylindrical) and has a first surface (upper surface in fig. 4 and 5) and a second surface (lower surface in fig. 4 and 5) on both sides in the axial direction thereof. The slot connecting portion 23 is provided on the first surface of the first housing 210, and the receiving portion 24, the first power supply terminal portion 26, and the first communication terminal portion 27 are accommodated in the first housing 210.

In addition, the first case 210 has a pair of

first connection holes

211, 211 and a pair of

second connection holes

212, 212 on the second surface.

The pair of

first connection holes

211, 211 are holes for connecting the second power supply terminal part 28 of the main body 22 and the first power supply terminal part 26 of the adapter 21. The pair of

first connection holes

211, 211 are located on the opposite side with respect to the center of the second surface of the first housing 210, and penetrate the second surface in the axial direction of the first housing 210. Each first connection hole 211 has a first hole portion 2111 and a second hole portion 2112 that are continuous in the circumferential direction of the second face of the first housing 210. The first hole 2111 and the second hole 2112 are each arc-shaped, but the width of the first hole 2111 is wider than the width of the second hole 2112.

The pair of second connection holes 212 and 212 are holes for connecting the second communication terminal portion 29 of the main body 22 and the first communication terminal portion 27 of the adapter 21. The pair of second connection holes 212 and 212 are located on the opposite side with respect to the center of the second surface of the first housing 210, and penetrate the second surface in the axial direction of the first housing 210. In the present embodiment, a straight line connecting the pair of first connection holes 211, 211 and a straight line connecting the pair of second connection holes 212, 212 are orthogonal to each other in a plane orthogonal to the axial direction of the first housing 210. Each of the second connection holes 212 has a first hole portion 2121 and a second hole portion 2122 continuous in the circumferential direction of the second surface of the first housing 210. The first hole 2121 and the second hole 2122 are each arc-shaped, but the width of the first hole 2121 is larger than the width of the second hole 2122.

The first housing 210 has an operation portion 213 on a side surface. The operation portion 213 is movable in the circumferential direction of the first housing 210. The operation portion 213 is used to operate the slot connecting portion 23. The details will be described later.

As shown in fig. 2 and 6, the slot connection portion 23 is used to attach the notification device 20 to the wiring slot 40.

Here, the wiring duct 40 is provided in advance in a facility to supply power to the equipment device 30. As shown in fig. 6, the wiring duct 40 includes a pair of conductors 41 and a housing 42 that houses the pair of

conductors

41 and 41. The housing 42 is a long hollow rectangular parallelepiped. The housing 42 has electrical insulation. The housing 42 is formed of, for example, a material having electrical insulation (e.g., a resin material). The housing 42 has an opening 43 extending in the longitudinal direction of the housing 42 on one surface (the lower surface in fig. 6) in the thickness direction. The pair of

conductors

41, 41 face each other in the width direction of the housing 42 (the left-right direction in fig. 6). The pair of

conductors

41, 41 extend in the longitudinal direction of the housing 42. The wiring duct 40 is installed in, for example, a ceiling of a facility.

As shown in fig. 6, the groove connection portion 23 includes a projection 230, a pair of

conductors

41 and 41, and a pair of

projections

232 and 232.

The protrusion 230 is disposed on the first surface of the first housing 210. The protrusion 230 is located at the center of the first surface of the first housing 210 in a direction facing the pair of second connection holes 212. The protrusion 230 is longer in a direction facing the pair of second connection holes 212 than in a direction facing the pair of first connection holes 211. Here, the dimension of the protrusion 230 in the short side direction (the direction facing the pair of second connection holes 212) is smaller than the width of the opening 43 of the wiring groove 40. In addition, both side surfaces of the protrusion 230 in the longitudinal direction (the direction facing the pair of first connection holes 211) are flush with the side surfaces of the first housing 210.

The pair of

terminals

231, 231 are electrically connected to the pair of

conductors

41, 41 of the wiring duct 40, respectively. A pair of

terminals

231, 231 project from both sides of the projection 230 in the short direction. The pair of

terminals

231 and 231 can move in the short side direction of the projection 230, and the amount of projection from the projection 230 can be varied.

The pair of

protrusions

232, 232 are physically supported at both edge portions of the opening 43 of the housing 42 of the wiring duct 40. A pair of

projections

232, 232 project from both sides in the short direction of the projection 230. The pair of

projections

232 and 232 are movable in the short side direction of the projection 230, and the amount of projection from the projection 230 is variable. The pair of

projections

232 and 232 are positioned on the first surface side of the first housing 210 with respect to the pair of

terminals

231 and 231.

In addition, the slot connecting portion 23 has a mechanism for adjusting the amount of projection of the pair of

terminals

231, 231 and the pair of

projections

232, 232 from the projection portion 230 in accordance with the operation of the operating portion 213. For example, the pair of terminals 231 and the pair of

projections

232 and 232 are received in the projection 230 by the operation of the operation portion 213. Thereby, the slot connection portion 23 can pass through the opening 43 of the wiring slot 40.

The adapter 21 having the groove connection portion 23 is attached to the wiring groove 40 as follows. First, the operation portion 213 is operated to accommodate the pair of terminals 231 and the pair of

projections

232 and 232 in the projection 230. In this state, the protrusion 230 is inserted into the housing 42 through the opening 43 of the wiring duct 40. After that, the operation portion 213 is operated so that the pair of

terminals

231, 231 and the pair of

projections

232, 232 project from the projection 230. As a result, as shown in fig. 6, the pair of

terminals

231 and 231 are in contact with and electrically connected to the pair of

conductors

41 and 41 of the wiring duct 40, respectively. Meanwhile, the pair of

projections

232, 232 are supported at both edge portions of the opening 43 of the housing 42. As a result, the slot connection portion 23 is physically attached to the wiring slot 40 and electrically connected to the wiring slot 40.

The receiving unit 24 includes a communication interface for power line transmission communication, and has a function of transmitting and receiving a communication signal for power line transmission communication. In addition, various well-known standards can be adopted as the Power line transmission Communication, and for example, High Definition Power line Communication (High Definition line Communication) is preferably adopted. Since the communication interface for the power line transmission communication may have a conventionally known configuration, a detailed description thereof will be omitted.

As shown in fig. 2, the receiving portion 24 is electrically connected to the pair of

terminals

231, 231 of the slot connecting portion 23. Therefore, by attaching the slot connection portion 23 to the wiring slot 40, the receiving portion 24 is electrically connected to the wiring slot 40 via the slot connection portion 23. Thus, the receiving section 24 has a function (receiving function) of receiving the communication signal (first communication signal) S10 based on the power line transmission communication from the wiring duct 40 via the duct connecting section 23. The receiving unit 24 has a function (transmitting function) of transmitting a communication signal (second communication signal) S11 based on the power line transmission communication to the wiring duct 40 via the duct connecting unit 23. That is, bidirectional communication can be performed by the receiving unit 24.

The receiving unit 24 is configured to convert the communication signal S10 received from the wiring duct 40 via the duct connecting unit 23 into a signal of a communication protocol different from the power line transmission communication and output the signal. As a signal of a communication protocol different from the power line transmission communication, for example, a signal conforming to the standard of Ethernet (registered trademark) or a serial signal can be cited. As shown in fig. 2, the receiving portion 24 is electrically connected to the first communication terminal portion 27. Thus, the receiving section 24 converts the communication signal S10 into a signal of a communication protocol different from the power line transmission communication and outputs the signal to the first communication terminal section 27. The receiving unit 24 can change the form of the signal to be output to the notification unit 25 according to the standard of the notification unit 25. This improves the degree of freedom in selection of the notification unit 25.

The first power supply terminal portion 26 is used to supply electric power from the wiring duct 40 to the main body 22. As shown in fig. 2, the first power supply terminal unit 26 has a pair of

power supply terminals

261 and 261. The pair of

power terminals

261, 261 are electrically connected to the pair of

terminals

231, 231 of the slot connecting portion 23, respectively. The pair of

power supply terminals

261, 261 are, for example, arc-shaped metal plates. The pair of

power terminals

261, 261 are housed in the first housing 210 as shown in fig. 5. Each power terminal 261 is located near the second hole portion 2112 of the corresponding first connection hole 211 and on the center side of the first housing 210.

The first communication terminal unit 27 is used to output a communication signal S10 from the wiring duct 40 to the main body 22. As shown in fig. 2, the first communication terminal section 27 has a pair of

communication terminals

271, 271. The pair of

communication terminals

271, 271 is electrically connected to the receiving unit 24. The pair of

communication terminals

271, 271 is, for example, an arc-shaped metal plate. As shown in fig. 5, the pair of

communication terminals

271 and 271 are housed in the first housing 210. Each communication terminal 271 is located near the second hole portion 2122 of the corresponding second connection hole 212 and on the center side of the first housing 210.

As shown in fig. 7, the main body 22 includes a second housing 220. As shown in fig. 2, the second housing 220 is provided with a notification portion 25, a second power supply terminal portion 28, and a second communication terminal portion 29.

The second housing 220 has a hollow cylindrical shape (right circular cylindrical shape) and has a first surface (upper surface in fig. 7) and a second surface (lower surface in fig. 7) on both sides in the axial direction. The second housing 220 has a shape in a plane orthogonal to the axial direction thereof, which conforms to the first housing 210. Therefore, as shown in fig. 3, the side surface of the second housing 220 is the same as the side surface of the first housing 210.

As shown in fig. 2, the notification unit 25 includes a display device 251 and a control circuit 252.

The display device 251 is a device for performing display. That is, the display device 251 can perform visual notification. As shown in fig. 7, the display device 251 includes a first light-emitting portion 2511, a second light-emitting portion 2512, and a third light-emitting portion 2513. The first light-emitting portion 2511, the second light-emitting portion 2512, and the third light-emitting portion 2513 are lamps that emit light of different colors from each other. For example, the first light emitting portion 2511 emits red light, the second light emitting portion 2512 emits yellow light, and the third light emitting portion 2513 emits green light. As shown in fig. 7, each of the first light emitting portion 2511, the second light emitting portion 2512, and the third light emitting portion 2513 is cylindrical with an equal outer diameter. The first light emitting portion 2511, the second light emitting portion 2512, and the third light emitting portion 2513 include, for example, a light-transmitting cylindrical housing and one or more light emitting elements (e.g., light emitting diodes) housed in the housing. In the present embodiment, the first light emitting portion 2511, the second light emitting portion 2512, and the third light emitting portion 2513 are attached to the center portion in the axial direction of the second housing 220, and are arranged in this order from the first surface side to the second surface side in the axial direction of the second housing 220.

The control circuit 252 can be realized by a microcomputer including a memory and a processor, for example. As shown in fig. 2, the control circuit 252 is electrically connected to the second power supply terminal unit 28 and the second communication terminal unit 29. The control circuit 252 (i.e., the notification unit 25) is configured to operate based on the electric power received from the wiring duct 40 via the duct connection unit 23, the first power supply terminal unit 26, and the second power supply terminal unit 28. The control circuit 252 is configured to cause the display device 251 to display a communication signal S10 received by the receiving unit 24. For example, if the communication signal S10 received by the receiving unit 24 indicates normal, the control circuit 252 may control the display device 251 to light the third light emitting unit 2513. In addition, if the communication signal S10 received by the receiving unit 24 indicates an abnormality, the control circuit 252 may control the display device 251 so that the second light emitting unit 2512 is turned on. Further, if the communication signal S10 received by the receiver 24 indicates the occurrence of an event, the control circuit 252 may control the display device 251 to turn on the first light-emitting portion 2511. In this way, the notification unit 25 is configured to perform notification in accordance with the communication signal S10 received by the reception unit 24. Further, when the communication signal S10 is received by the receiving unit 24, the control circuit 252 may be configured to output the communication signal S1, which is a confirmation of the reception of the communication signal S10, from the receiving unit 24 to the wiring duct 40.

The second power supply terminal portion 28 is used for receiving power from the wiring duct 40 via the adapter 21. In particular, the second power supply terminal unit 28 is detachably coupled to the first power supply terminal unit 26. In more detail, as shown in fig. 2 and 7, the second power terminal unit 28 has a pair of

power terminals

281 and 281. The pair of

power supply terminals

281 and 281 are electrically connected to the notification unit 25 (control circuit 252). Each power terminal 281 is formed in an L shape using metal. More specifically, each power terminal 281 includes a first tab 2811 and a second tab 2812. The first sheet 2811 protrudes from a first face (upper face in fig. 7) of the second housing 220 in the axial direction of the second housing 220. The second sheet 2812 protrudes from the first sheet 2811 toward the center side of the second housing 220. Here, the second sheet 2812 can pass through the first hole portion 2111 of the first connection hole 211, but the second hole portion 2112 has a size such that the second sheet 2812 cannot pass through. The pair of

power terminals

281 and 281 are located on the opposite side with respect to the center of the first surface of the second housing 220.

The second communication terminal unit 29 is used for receiving a signal from the receiving unit 24. In particular, the second communication terminal unit 29 is detachably coupled to the first communication terminal unit 27. More specifically, as shown in fig. 2 and 7, the second communication terminal unit 29 includes a pair of

communication terminals

291 and 291. The pair of

communication terminals

291 and 291 are electrically connected to the notification unit 25 (control circuit 252). Each communication terminal 291 is formed in an L shape using a metal. More specifically, each communication terminal 291 includes a first piece 2911 and a second piece 2912. The first piece 2911 protrudes from the first surface (upper surface in fig. 7) of the second housing 220 in the axial direction of the second housing 220. The second tab 2912 protrudes from the first tab 2911 toward the center side of the second housing 220. Here, the second piece 2912 can pass through the first hole 2121 of the second connection hole 212, but the second hole 2122 has a size such that the second piece 2912 cannot pass through. The pair of

communication terminals

291, 291 are located on opposite sides with respect to the center of the first surface of the second housing 220. In the present embodiment, a straight line connecting the pair of power terminals 281 and a straight line connecting the pair of

communication terminals

291 and 291 are orthogonal to each other in a plane orthogonal to the axial direction of the second housing 220.

In the notification device 20, the main body 22 is attached to the adapter 21 as follows. First, the pair of

power terminals

281 and 281 of the second power terminal portion 28 of the main body 22 is inserted into the first housing 210 of the adapter 21 through the

first hole portions

2111 and 2111 of the pair of first connection holes 211 and 211 of the adapter 21. Meanwhile, the pair of

communication terminals

291, 291 of the second communication terminal portion 29 of the main body 22 is inserted into the first housing 210 of the adaptor 21 through the first hole portions 2121, 2121 of the pair of second connection holes 212, 212 of the adaptor 21. Thereafter, the second housing 220 of the main body 22 is rotated about the direction of its center axis with respect to the adapter 21. Thereby, each power terminal 281 is moved from the first hole 2111 to the second hole 2112 of the corresponding first connection hole 211, and each communication terminal 291 is moved from the first hole 2121 to the second hole 2122 of the corresponding second connection hole 212. Thus, the second sheet 2812 of the pair of power terminals 281 is positioned above the pair of power terminals 261 and supported by the pair of power terminals 261. Similarly, the second piece 2912 of the pair of communication terminals 291 is positioned on the pair of communication terminals 271 and supported by the pair of communication terminals 271. Thereby, the main body 22 is attached to the adapter 21.

On the other hand, in the notification device 20, the main body 22 is detached from the adapter 21 as follows. First, the second housing 220 of the main body 22 is rotated about the direction of its center axis with respect to the adapter 21. Thereby, each power terminal 281 is moved from the second hole portion 2112 of the corresponding first connection hole 211 to the first hole portion 2111, and each communication terminal 291 is moved from the second hole portion 2122 of the corresponding second connection hole 212 to the first hole portion 2121. Thus, the second tab 2812 of the pair of power terminals 281 is not positioned on the pair of power terminals 261 and is not supported by the pair of power terminals 261. Similarly, the second piece 2912 of the pair of communication terminals 291 is not positioned on the pair of communication terminals 271 and is not supported by the pair of communication terminals 271. Thereafter, the pair of

power terminals

281 and 281 of the second power terminal portion 28 of the main body 22 are pulled out from the first case 210 of the adapter 21 through the

first hole portions

2111 and 2111 of the pair of first connection holes 211 and 211 of the adapter 21. At the same time, the pair of

communication terminals

291, 291 of the second communication terminal portion 29 of the main body 22 is pulled out from the first housing 210 of the adaptor 21 through the first hole portions 2121, 2121 of the pair of second connection holes 212, 212 of the adaptor 21. Thereby, the main body 22 is detached from the adapter 21.

In this way, the second power supply terminal part 28 and the second communication terminal part 29 of the main body 22 are detachably coupled to the first power supply terminal part 26 and the first communication terminal part 27 of the adapter 21, respectively.

The equipment device 30 is a device used when producing an article. The facility apparatus 30 is an apparatus for processing and treating an article, and examples thereof include a heating apparatus, a cooling apparatus, a molding apparatus (an injection molding apparatus, an extrusion molding apparatus, a vacuum molding apparatus, and an air compression molding apparatus), a plating apparatus, an assembling apparatus, a stirring apparatus, and a film forming apparatus. In addition to the above-described devices, the equipment device 30 may be a device (e.g., a conveyor) used when an article is conveyed, a device (e.g., an appearance inspection device) used when an article is measured and inspected, or the like. The equipment device 30 is electrically connected to the wiring duct 40 via a cable 31. The device apparatus 30 functions as a transmission unit that transmits a communication signal S11 based on power line transmission communication to the reception unit 24 via the wiring duct 40. For example, when an abnormality of the device 30 is detected, the device 30 outputs a communication signal S10 indicating the abnormality to the wiring duct 40. The device apparatus 30 may periodically output the communication signal S10 indicating an abnormality to the wiring duct 40 until receiving the communication signal S11 as a reception confirmation of the communication signal S10 from the receiving unit 24. Further, if the device 30 is not abnormal, the device 30 may output a communication signal S10 indicating normality to the wiring duct 40.

The detection device 50 is a device that detects a predetermined event. Examples of the predetermined event include a fire, detection of a person (intrusion of a person into an entrance-prohibited place), and the like. The detection device 50 is physically mounted to the wiring duct 40 and electrically connected to the wiring duct 40. The detection device 50 functions as a transmission unit that transmits a communication signal S10 based on power line transmission communication to the reception unit 24 via the wiring duct 40. For example, when detecting a predetermined event, the detection device 50 outputs a communication signal S10 indicating the occurrence of the event to the wiring duct 40. The detection device 50 may output the communication signal S10 indicating the occurrence of the event to the wiring duct 40 until the communication signal S11 is received from the reception unit 24 as a reception confirmation of the communication signal S10.

1.1.3 actions

Next, the operation of the notification system 10 will be briefly described with reference to fig. 1. When the device apparatus 30 outputs the communication signal S10 indicating the normality to the wiring duct 40, the notification apparatus 20 receives the communication signal S10 via the wiring duct 40 and performs notification in accordance with the communication signal S10. Here, since the communication signal S10 indicates normal, the notification unit 25 of the notification device 20 lights the third light emitting unit 2513 of the display device 251. When the equipment device 30 outputs the communication signal S10 indicating the abnormality to the wiring duct 40, the notification device 20 receives the communication signal S10 via the wiring duct 40 and performs a notification corresponding to the communication signal S10. Here, since the communication signal S10 indicates an abnormality, the notification unit 25 of the notification device 20 lights up the second light emitting unit 2512 of the display device 251. When the detection device 50 outputs the communication signal S10 indicating the occurrence of the event to the wiring duct 40, the notification device 20 receives the communication signal S10 via the wiring duct 40 and performs notification in accordance with the communication signal S10. Here, since the communication signal S10 indicates the occurrence of an event, the notification unit 25 of the notification device 20 lights the first light emitting unit 2511 of the display device 251.

Thus, the notification system 10 performs display corresponding to the communication signal S10. In particular, since the notification device 20 including the notification unit 25 is mounted on the wiring duct 40 provided on the ceiling, the display of the notification unit 25 of the notification device 20 is easily visually recognized by a person in the facility. In addition, since the wiring duct 40 provided in advance in the facility is used as the path of the communication signal S10, it is possible to eliminate the need for constructing a path for communication with the notification unit 25, and to improve the safety and reliability of communication with the notification unit 25.

1.2 embodiment 2

The notification system 10 of the present embodiment includes a notification device 20A shown in fig. 8 instead of the notification device 20.

Fig. 8 is a block diagram of the circuit configuration of the notification device 20A. As shown in fig. 8, the notification device 20A is constituted by an adapter 21A and a main body 22A. The notification device 20A as a whole includes a slot connection portion 23, a receiving portion 24, a notification portion 25, a first power supply terminal portion 26, and a second power supply terminal portion 28. Unlike embodiment 1, the notification device 20A does not include the first communication terminal section 27 and the second communication terminal section 29.

As shown in fig. 8 and 9, the adapter 21A includes a first housing 210. As shown in fig. 8, a slotted connection portion 23 and a first power supply terminal portion 26 are provided in the first housing 210.

The difference from embodiment 1 is that the first housing 210 does not have a pair of second connection holes 212 and 212 on the second surface.

The groove connecting portion 23 is provided on the first surface of the first housing 210, as in embodiment 1.

As in embodiment 1, the first power terminal unit 26 has a pair of power terminals 261, and the pair of power terminals 261 are housed in the first housing 210.

As shown in fig. 8 and 10, the main body 22A includes a second housing 220. As shown in fig. 8, the second housing 220 is provided with a receiving portion 24, a notification portion 25, and a second power supply terminal portion 28.

The second housing 220 is different from embodiment 1 in that the pair of

communication terminals

291 and 291 of the second communication terminal unit 29 are not provided on the first surface.

As shown in fig. 8, the receiving unit 24 is electrically connected to a pair of

power terminals

281 and 281 of the second power terminal unit 28. That is, in the notification device 20A, the receiving portion 24 receives the communication signal S10 from the wiring duct 40 via the duct connecting portion 23, the first power supply terminal portion 26, and the second power supply terminal portion 28. Further, the receiving unit 24 transmits a communication signal S11 based on power line transmission communication to the wiring duct 40 via the duct connecting portion 23, the first power supply terminal portion 26, and the second power supply terminal portion 28. The receiving unit 24 is connected to the notification unit 25. Thereby, the receiving unit 24 converts the communication signal S10 into a signal of a communication protocol different from the power line transmission communication, and outputs the signal to the notification unit 25.

As shown in fig. 8, the notification unit 25 (control circuit 252) is electrically connected to the pair of

power terminals

281 and 281 of the second power terminal unit 28. The control circuit 252 (i.e., the notification unit 25) is configured to operate based on the electric power received from the wiring duct 40 via the duct connection unit 23, the first power supply terminal unit 26, and the second power supply terminal unit 28.

The second power supply terminal unit 28 has a pair of

power supply terminals

281 and 281, as in embodiment 1. The pair of

power terminals

281 and 281 protrude from the first surface of the second housing 220, and are located on the opposite side with respect to the center of the first surface.

In the notification device 20A, the main body 22A is attached to the adapter 21A as follows. First, the pair of

power terminals

281 and 281 of the second power terminal portion 28 of the main body 22A is inserted into the first housing 210 of the adapter 21 through the

first hole portions

2111 and 2111 of the pair of first connection holes 211 and 211 of the adapter 21A. Thereafter, the second housing 220 of the main body 22A is rotated about the direction of the central axis thereof with respect to the adapter 21A. Thereby, each power terminal 281 is moved from the first hole portion 2111 to the second hole portion 2112 of the corresponding first connection hole 211. Thus, the second piece 2812 of the pair of power terminals 281 is positioned on the pair of power terminals 261 and supported by the pair of power terminals 261. Thereby, the main body 22A is attached to the adapter 21A.

On the other hand, in the notification device 20A, the main body 22A is detached from the adapter 21A as follows. First, the second housing 220 of the main body 22A is rotated about the direction of its center axis with respect to the adapter 21. Thereby, each power terminal 281 is moved from the second hole portion 2112 of the corresponding first connection hole 211 to the first hole portion 2111. Thus, the second tab 2812 of the pair of power terminals 281 is not positioned on the pair of power terminals 261 and is not supported by the pair of power terminals 261. Thereafter, the pair of

power terminals

281 and 281 of the second power terminal portion 28 of the main body 22A are pulled out from the first case 210 of the adapter 21 through the

first hole portions

2111 and 2111 of the pair of first connection holes 211 and 211 of the adapter 21A. Thereby, the main body 22A is detached from the adapter 21A.

In this way, the second power supply terminal unit 28 of the main body 22A is detachably coupled to the first power supply terminal unit 26 of the adapter 21A. That is, in the notification device 20A, the second housing 220 is detachably attached to the first housing 210 by the second power supply terminal portion 28 and the first power supply terminal portion 26. In other words, the notification device 20A includes the first housing 210 for providing the groove connection portion 23, and the second housing 220 for providing the notification portion 25 and detachably attached to the first housing 210. Therefore, the notification portion 25 can be replaced together with the second housing 220.

In the notification device 20A, the first housing 210 has the first power supply terminal portion 26 electrically connected to the slot connecting portion 23. The second housing 220 has a second power supply terminal portion 28 detachably coupled to the first power supply terminal portion 26. The receiving portion 24 is disposed in the second housing 220 and electrically connected to the second power terminal portion 28.

Thus, the receiving section 24 receives the communication signal S10 based on the power line transmission communication from the wiring duct 40 via the duct connecting section 23. Further, the receiving section 24 transmits a communication signal S11 based on the power line transmission communication to the wiring duct 40 via the duct connecting section 23. The receiving unit 24 is connected to the notification unit 25. Thereby, the receiving unit 24 converts the communication signal S10 into a signal of a communication protocol different from the power line transmission communication, and outputs the signal to the notification unit 25.

As in embodiment 1, the display device 251 of the notification unit 25 includes a first light emitting unit 2511, a second light emitting unit 2512, and a third light emitting unit 2513.

In this way, the notification device 20B further includes a housing 200 for providing the groove connection portion 23, the receiving portion 24, and the notification portion 25. According to the notification device 20B, the construction work is facilitated.

In the notification device 20B, the notification unit 25 is configured to operate based on the electric power received from the wiring duct 40 via the duct connection portion 23. According to the notification device 20B, the notification unit 25 can be operated by supplying power to the notification unit 25 through the wiring duct 40. Therefore, it is not necessary to perform a task of periodically replacing the battery of the notification unit 25, and the convenience is improved.

2. Modification example

The embodiments of the present disclosure are not limited to the above embodiments. The above embodiment can be variously modified according to design and the like if the problem of the present disclosure can be achieved. Modifications of the above embodiment will be described below.

For example, although the notification system 10 includes one notification device (20; 20A; 20B) in the above embodiment, the number of notification devices (20; 20A; 20B) is not particularly limited. The notification system 10 may also have more than one notification device (20; 20A; 20B). Further, in the case where the notification system 10 has a plurality of notification devices (20, 20A, 20B), the destination of the communication signal S10 may be specified by including the addresses of the notification devices (20, 20A, 20B) in the communication signal S10.

The notification device (20; 20A; 20B) is not limited to the above configuration. In particular, the shapes of the slot connecting portion 23, the first power supply terminal portion 26, the first communication terminal portion 27, the second power supply terminal portion 28, and the second communication terminal portion 29 can be any conventionally known shapes as long as the functions thereof can be realized. For example, the shape of the slot connecting portion 23 may be changed according to the shape of the wiring slot 40. Further, the first power supply terminal unit 26, the first communication terminal unit 27, the second power supply terminal unit 28, and the second communication terminal unit 29 are coupled to the suspension holder and the socket. The shapes of the case 200, the first case 210, and the second case 220 are not limited to the above shapes, and may be changed according to design, desire, and the like. For example, the housing 200, the first housing 210, and the second housing 220 may not be cylindrical but may be prismatic. In embodiments 1 and 2, the second housing 220 can be detachably mounted to the first housing 210 by using at least the first power supply terminal portion 26 and the second power supply terminal portion 28. However, the second housing 220 may be detachably mounted to the first housing 210 using a snap structure.

In the above-described embodiments, the notification device (20; 20A; 20B) is a display (signal display) that causes the lamp (display device 251) to light up in accordance with the signal (communication signal S10).

The communication means transmits a signal from the notification portion 25 to other devices (e.g., an alarm and a notifier), for example, by infrared communication or visible light communication. The device that receives the signal from the notification unit performs a predetermined process such as notification. This enables notification by linking a plurality of devices.

The operation of the control circuit 252 is not limited to the above-described operation. The operation of the control circuit 252 may be changed as appropriate in accordance with the content indicated by the communication signal S10. For example, the control circuit 252 may turn on all the

light emitting units

2511, 2512, and 2513 of the display device 251, or may turn on at least one of the

light emitting units

2511, 2512, and 2513. The content indicated by the communication signal S10 transmitted from the equipment device 30 is not limited to normality or abnormality of the equipment device 30, and may include an operation state of the equipment device 30 and arrival of a maintenance timing.

The notification unit 25 may be configured to include a battery and be operated by electric power from the battery. In this case, the notification unit 25 does not necessarily need to obtain power from the wiring duct 40. The notification unit 25 may have a charging circuit for charging the battery. Thus, the notification unit 25 can operate even when power cannot be received from the wiring duct 40.

The wiring duct 40 is not particularly limited to the above configuration, and may be a conventionally known configuration (for example, a lamp rail or a lighting rail). That is, if the track is provided in the facility to supply power to the electric devices in the facility, the track can be used as the wiring duct 40. In the above embodiment, the wiring duct 40 is provided on the ceiling of the facility, but may be provided on the wall of the facility. The installation place of the wiring duct 40 is not particularly limited.

In the above embodiment, the device apparatus 30 and the detection apparatus 50 function as a transmission unit. However, the transmission unit may be a device other than the equipment device 30 and the detection device 50. The transmission unit may be a controller for remotely controlling the notification device 20 by a person, for example. Such a controller can be implemented by a portable terminal such as a smartphone or a tablet terminal, or a personal computer.

In addition, in the notification system 10, the wiring duct 40 and the transmission section (the equipment device 30 and the detection device 50) are not necessary. That is, the notification system 10 may include at least the notification devices (20, 20A, 20B). The notification device (20, 20A, 20B) may include at least the slot connection portion 23, the receiving portion 24, and the notification portion 25.
