Corresponding to a third connecting portion electrically connected, the connector 7 comprising the connected portion 7A and the connected portion 7B of the communication device 8a receives power supply from the first connecting portion, and receives the first connecting portion. This corresponds to a fourth connection unit for exchanging information signals with the.

  Further, when the power connector 11A and the information connector 11B of the monitor device 10b are connected to the power connector 9A and the information connector 9B of the communication device 8a, the power connector 11A and the information connector 11B of the monitor device 10b are the first. The power connector 9A and the information connector 9B of the communication device 8a are electrically connected directly to the first connection portion (the power connector 11A and the information connector 11B) of the monitor device 10b. This corresponds to a second connection unit for transferring power and signals to and from the first connection unit.

  Therefore, by connecting the communication device 8a and the monitor device 10b with a connector, it is possible to mutually supply power and exchange information signals, and the monitor device 10b can be easily added to the communication device 8a installed in advance. And excellent extensibility can be obtained.

  In addition, the communication device 8a can be secured to the power line L1 and the information line L2 that are preliminarily wired in advance through the gate device 3, so that the power path and the information path can be secured at the same time, and a new wiring work needs to be performed. No workability and excellent workability. Further, by using the same information line L2 as the other basic function module 8 and the extended function module 10, it is possible to easily perform the interlock control between the communication device 8a and the other basic function module 8 and the extended function module 10. Can be expanded and has excellent extensibility.

  With respect to the operation when used in an interphone system for making a call with other call devices connected to the wiring system in such call devices 8a, 10a and monitor device 10b, the schematic diagram of FIG. 6 is used. I will explain. In FIG. 6, the power line L1, the gate device 3 and the like are omitted, and transmission / reception of information signals between the devices via the information line L2 will be described.

  First, the intercom system is connected to five communication devices 8a and 10a installed in each room including a bathroom and an interphone handset 120 installed on the outdoor side of the entrance. , 10a stores the ID information of the own device in the first ID storage unit 35j, and stores the ID information of other communication devices in the second ID storage unit 35k. In FIG. 6, “1”, “2”, “3”, “4”, “5”, and “6” are the communication devices 10 a (1), 10 a (2), 8 a (3), 10 a (4), 8 a as ID information. (5) and the interphone slave unit 120 are allocated respectively.

  Here, among the communication devices 10a (1), 10a (2), 8a (3), 10a (4), and 8a (5), the communication device 10a (1) (hereinafter referred to as the call master device 10a (1)). ) Has a function as an interphone master, and, as shown in FIG. 7, includes a transmission processing unit 37 (transmission processing means) in addition to the same functions as those of other telephone apparatuses.

  The transmission processing unit 37 relays the digital information signal from each functional device and performs an operation of transmitting the digital information signal to the corresponding functional device with reference to the ID information included in the information signal. Specifically, the transmission processing unit 37 generates a synchronization signal, performs a multiplex transmission process of the digital information signal relayed by the transmission processing unit 37 based on the synchronization signal, and transmits the synchronization signal to the information line L2. Thus, each functional device also performs a multiplex transmission process of the digital information signal based on the synchronization signal. Thus, communication efficiency is improved by performing multiple channel control (such as time division multiplexing control) on digital information signals exchanged with a plurality of functional devices.

  In addition, the communication devices 10a (2), 8a (3), 10a (4), and 8a (5) relay the transmission processing unit 37 of the call parent device 10a (1) to and from the interphone slave unit 120. This corresponds to an interphone sub-master device capable of transmitting image signals and audio signals.

  As described above, the intercom system includes the interphone handset 120, the call parent device 10a (1) (interphone parent device), and the call devices 10a (2), 8a (3), 10a (4), and 8a (5). (Interphone sub-master) and between the interphone slave unit 120 and the call master 10a or the call device 10a (2), 8a (3), 10a (4), 8a (5), or the call master 10a And a communication device 10a (2), 8a (3), 10a (4), and 8a (5).

  In the present embodiment, the quality of communication is improved by using a digital signal as an information signal transmitted through the information line L2.

  The call destination selection switches SW1 to SW7 of the call devices 8a and 10a correspond to the call devices (up to 7) installed in other rooms, respectively, and any one of the call destination selection switches SW1 to SW7. Then, when the call switch SW9 is operated, the information signal multiplex transmission processing unit 33 identifies the ID of the call device corresponding to the operated call destination selection switch among the ID information stored in the second ID storage unit 35k. Information is transmitted to the information line L 2 via the multiplexing / demultiplexing unit 32.

  For example, the operation when the call device 8a (3) assigned ID information “3” places a call to the call device 10a (4) assigned ID information “4” will be described with reference to the operation flowchart of FIG. To do. When the call switch SW9 of the call device 8a (3) is operated and then the call switch SW9 is operated (step S1), an information signal including ID information “4” is transmitted from the call device 8a (3) to the information line L2. (Step S2). This information signal is transmitted to the call device 10a (4) via the transmission processing unit 37 of the call parent device 10a (1), and the information signal multiplex transmission processing unit 33 of the call device 10a (4) If the ID information stored in the ID storage unit 35j matches the ID information included in the received information signal (step S3), a call path is established with the call device 8a (3) as the transmission source. (Step S4). At the end of the call, the call switch SW9 is operated again (step S5), and the call path is blocked (step S6).

  Further, if the simultaneous notification switch SW8 of the call device 8a (3) is operated, an information signal including ID information of all call devices stored in the second ID storage unit 35k of the call device 8a (3) is displayed as information. It is transmitted to the line L2, and a communication path is established between all the other communication devices 10a (1), 10a (2), 10a (4), and 8a (5) and can be broadcast simultaneously.

  Further, a human sensor 130 is provided in the room where the communication devices 8 a and 10 a are installed, and the communication device 8 a (3) is installed in the room where the human body detection signal is transmitted from the human sensor 130. You may broadcast to only the telephone device.

  Further, the intercom handset 120 operates the call switch SW10 to establish a communication path with the main device 10a (1), and to the other communication device 10a (2), via the transmission processing unit 37. It is also possible to establish a communication path with 8a (3), 10a (4), and 8a (5). The intercom handset 120 may use the communication devices 8a and 10a.

  On the other hand, the monitor device 10b is connected to the call master unit 10a (1), and automatically monitors when an image signal is transmitted from the camera 121 included in the intercom handset 120 via the transmission processing unit 37. The power of the screen 35n is turned on, and it is possible to monitor the state of visitors and the vicinity of the entrance. Further, the monitor function can be turned on / off by operating the display switch SW12. The monitor device 10b may be connected to other communication devices 8a and 10a. In this case, the image signal is transmitted to the monitor device 10b via the transmission processing unit 37.

  Thus, since wired communication is performed via the information line L2, signal leakage can be prevented compared to wireless communication, and it can be safely used in apartment houses such as apartments and apartments. In addition, by performing multiplex communication via the information line L2, restrictions on the number of channels are relaxed compared to radio.

  Furthermore, since ID information is assigned to each of the call devices 8a and 10a and the interphone slave unit 120 and a call path is established using the ID information, call control of many call devices can be easily performed.

  In addition to the above, the basic function module 8 used in this wiring system includes those having an outlet function, those having a monitor function similar to the monitor device 10b, those having only a speaker function, etc. In addition to the above, the functional module 10 includes an air conditioner operation controller, an air conditioner temperature setting device, an electric razor using electric power supply, an electric toothbrush, a charger such as a portable audio player, a lighting device, an air conditioner, etc. There are those having infrared remote control.

  In addition, as a transmission system of the information signal of the wiring system using the functional device of the present invention, either baseband transmission or broadband transmission may be adopted and any protocol may be used. A pair of voice and video is sent to and from the master unit and slave unit based on the JT-H232 packet, and one or more can be operated by the operation data from the operation side in the control system. A route control protocol corresponding to unicast and broadcast capable of one-to-one or one-to-N correspondence may be employed, and is not particularly limited, and thus description thereof is omitted. Further, the protocol used between the gate devices 3 and the protocol used in the functional modules 8 and 10 connected to the gate device 3 may be made different, for example, the protocol conversion may be performed by the gate device 3.

  Thus, in using the basic function module 8 constituting the functional device, first, the gate device 3 is first attached to the switch box 2 embedded in the appropriate wall surface of the building via the mounting frame 4 and wired in advance. The power line L1 and the information line L2 are connected. Thereafter, the corresponding connected portions 7A and 7B of the connector 7 of the basic function module 8 are connected to the electric wire connection ports 6A and 6B provided on the front surface portion of the gate device 3, and the basic function module 8 is connected to the gate device. 3 is attached to the attachment frame 4 so as to cover the front surface portion of the frame 3. When the basic function module 8 is attached, the front surface portion protrudes from the wall surface, and both side surfaces are exposed to the indoor side.

  Then, the extended function module 10 is connected to one of the exposed side surfaces of the basic function module 8 by connecting the side surface of one side to the connector, and in this state, the extended function module 10 and the basic function module 8 are connected using the coupling body 100. Connect mechanically. Thereby, the basic function module 8 and the extended function module 10 constitute a functional device. At this time, the back surface of the extended function module 10 is along the side wall surface of the switch box 2. For example, when the wall surface is cross-bonded or the like, the position of the back surface of the extended function module 10 is slightly shifted. In addition, it can be disposed in a state in which the back surface is in close contact with the wall portion, and even if an operation force or the like is applied from the front surface portion of the extended function module 10, the load applied to the connection portion can be reduced.

  Further, when another extended function module 10 is connected to the previously connected extended function module 10, the extended function modules 10 are mechanically connected to each other by the connecting body 100 in a state where the opposing side surfaces are in contact with each other and are connected by connectors. In this manner, as shown in FIG. 1, the extended function modules 10 (10a, 10b...) Can be sequentially connected to the sides.

  Since the basic function module 8 can connect the extended function module 10 to both sides, the extended function module 10 may be connected to both sides of the basic function module 8. After the extended function module 10 is connected in this way, the end cover 101 is detachably attached to the side of the connection portion of the extended function module 10 or the basic function module 8 located at both ends, so that the extended function module 10 is attached. Will be completed. When the extended function module 9 is not connected to the basic function module 8, that is, when it is left unused, the end cover 101 is attached to both sides of the basic function module 8.

  The frame composed of the upper and lower sides of the decorative cover 8B of the basic function module 8, the lid 83 provided on the upper and lower sides of the extended function module 10 (including the communication device 10a), and the end cover 101 is standardized by JIS. It has substantially the same shape as the wide handle type switch plate (JIS8316), and it provides a uniform appearance with a wide handle type switch that has already been installed. Note that the shape of the frame is not limited to the shape of the wide handle type switch plate, but if the shape is substantially the same as the plate used for the large-angle continuous wiring apparatus standardized by JIS, It is possible to obtain a uniform appearance with an embedded wiring device such as the above.

  Further, the dimensions of the basic function module 8 and the extended function module 10 in the width direction and the height direction are the plate used for the large-angle continuous wiring apparatus standardized by JIS with the end covers 101 attached to both sides. The basic function module 8 and the extended function module 10 are formed to have the same dimensions, and the thickness dimensions of the basic function module 8 and the extended function module 10 are the same. Can be easily replaced.

  In addition, the number of extended function modules 10 that can be connected to the basic function module 8 is limited by the magnitude of the load applied to the connection site, and is also limited by the power supply capability of the basic function module 8.

  Here, for example, as shown in FIG. 9, the gate device of the switch box 2 provided in a high position HP such as an indoor ceiling surface among the one or a plurality of switch boxes 2 which are embedded and disposed at appropriate positions in the building. 3 is connected to a basic function module 8 having a hooking blade connecting portion 60, and the basic function module 8 is connected to an extended function module 10 provided with a human sensor 61 or the like, or a gate device 3 A basic function module 8c having only a speaker SP and having a function for BGM and the like is connected.

  A basic function module 8b constituting a wall switch for turning on / off a lighting fixture is provided in the gate device 3 of the switch box 2 provided at a height position (middle position MP) such as a wall surface recommended by a wall switch or the like. In addition, a monitor device 10b having a monitor function and a communication device 10a are connected. Alternatively, the basic function module 8 including the monitor device 64 is connected to the gate device 3 of the switch box 2 in the middle position MP.

  Furthermore, a basic function module 8 having a power outlet 62 is connected to the gate device 3 of the switch box 2 provided in the vicinity of the foot including the floor (low position LP), and an extended function module constituting the foot lamp 63. Or a basic function module 8c having only a speaker SP and having a function for BGM or the like is connected to the gate device 3.

  After the installation work is completed and the system is completed as described above, information signals are exchanged between the corresponding basic function module 8 and the extended function module 10, and if the call device 10a is used, a call in another room is performed. An intercom system is configured with the apparatus 10a, and a telephone call can be made between the two, and alarm notification is performed.

  Further, in this embodiment, no special construction is required for the addition or deletion of the extended function module 10 or the basic function module 8, and therefore, only by connecting the extended function module 10 to the basic function module 8 according to general user preference, Extensibility is ensured.

  Although the gate device 3 used in the present embodiment is attached to the switch box 2 with the attachment frame 4, it is of course possible to attach it directly to the back wall of the switch box 2 and attach the basic function module 8 to the switch box 2.

(Embodiment 2)
In the first embodiment, a power path and an information path are established by connector connection between the gate device 3, the basic function module 8 (including the call device 8a), and the extended function module 10 (including the call device 10a). .

  However, in this embodiment, the power path is configured by supplying electric power in a non-contact manner by magnetic coupling instead of connector connection. Specifically, the gate device 3, the basic function module 8, and the extended function module 10 each have a configuration in which a coil is wound around a core instead of a connector, and the cores are magnetically coupled to each other so that the other coil has a low pressure. AC power supply voltage is induced to supply power. Here, by applying an AC power supply having a frequency higher than the commercial frequency to the coil, the transformer configuration by the electromagnetic coupling portion can be reduced in size.

  Further, in the gate device 3, the basic function module 8, and the extended function module 10, an information signal is sent out through E / O conversion, and an information signal is taken in through O / E conversion, whereby an information signal composed of an optical signal is emitted as a light emitting element. Thus, an information path that can be transmitted bidirectionally without contact using the light receiving element is constructed.

(Embodiment 3)
In the first and second embodiments, power (power supply) transmission and information signal delivery are performed in separate systems, but in this embodiment, the information signal transmission method for the entire system is performed on the power line carrier to The road and information path are shared.

  That is, the preceding wiring in each switch box 2 is only the power line L1, and the connection port of the gate device 3 is only the power path connection port 6A of the connection port shown in FIG. The connector 7 (including the communication device 8a) also has only a connected port 7A corresponding to the power path connecting port 6A, and the information connectors 9B and 9B ′ are also omitted. Further, the extended function module 10 (including the communication device 10a) also omits the information connectors 11B and 11B '.

  Then, as shown in FIG. 20, in the communication device 10a, the information signal by the power line carrier is received and the PLC modem unit 36 for transmitting the information signal, and the data is transmitted by multiplex transmission through the PLC modem unit 36. An information signal multiplex transmission processing unit 33 to be exchanged, a function unit 35, and an I / O interface 34 provided between the function unit 35 and the information signal multiplex transmission processing unit 33 are provided. The information signal multiplex transmission processing unit 33, the I / O interface 34, and the function unit 35 have the same functions as those in the first embodiment.

  Further, the same configuration as the PLC modem unit 36 is also provided in the gate device 3, the basic function module 8, and the extended function module 10.

  The power line carrier modulation scheme employed in this embodiment may be any of various schemes such as a broadband spread spectrum scheme, a multi-carrier scheme, and an OFDM scheme, and is not particularly described here.

  Thus, in this embodiment, since the power path and the information path are common, the connection port in the gate device 3 is only the power path connection port 6A, and the connector 7 of the basic function module 8 is also one connected portion 7A. Thus, the connector 11 of the extended function module 10 also has only one connected portion 11A, so that the space around the connection is reduced. In addition, the internal circuit of the basic function module 8 or the extended function module 10 does not require a multiplexing / separating unit or an information connector, and thus the layout space in the thin module bodies 8A and 10A can be increased.

  In addition, since a PLC modem part is built in the lighting equipment and air conditioning equipment, it is possible to send information signals directly to the lighting equipment and air conditioning equipment, so it is necessary to provide a function module with an infrared remote control signal transmission function for remote control.
