Etc. That is, it functions as an intercom that allows two-way calls between rooms.

  In the present embodiment, the microphone M1 is disposed in the vicinity of the speaker SP, and the following processing is performed to prevent howling that occurs when the microphone M1 picks up the sound output of the speaker SP. First, the echo cancel unit 35c cancels the audio information signal that has passed from the speaker SP to the microphone M1 by taking the output of the echo cancel unit 35d as a reference signal and performing an operation on the output of the amplification unit 35b. Is. Further, the echo canceling unit 35d takes the output of the echo canceling unit 35c as a reference signal, and performs an operation on the output of the I / O interface 34, so that an audio information signal from the speaker to the microphone on the other party side of the call destination It also cancels out wraparound.

And an information signal output unit 354 that outputs an information signal based on the recognition result of the collation unit 353. Here, the acoustic model is a speech word dictionary created based on average pronunciation data.

  For the collation (matching) in the collation unit 353, the waveform of the audio signal from the acoustic signal analysis unit 350 and the acoustic model storage unit 352 are stored using a theory called HMM (Hidden Markov Model Hidden Markov Model). To match the acoustic model.

  For example, when recognizing the word “Please turn on electricity”, the candidate for collation when the first word “de” is recognized is a word that starts with “de” stored in the language model storage unit 351. It is narrowed down to. Next, the candidates for matching when the word “den” is recognized are “electricity”, “electric wire”,. . . The target is narrowed down to “Electricity” at the time when “Applying Electric Power” is recognized, and then the candidates for matching are gradually narrowed down. Please "is the recognition result. The verification operation is performed in a cycle of 10 to 20 milliseconds.

  Words that are not in the language model storage unit 351 are treated as unknown words and are not recognized. Therefore, it is necessary to tune the language model storage unit 351 in advance in consideration of the application, CPU processing capacity, usable memory capacity, and the like. Further, by feeding back the recognition result, the language model in the language model storage unit 351 is optimally corrected.

  And the information signal output part 354 outputs an information signal based on the recognition result of the collation part 353, but in this embodiment, it outputs the control command which controls operation | movement of another functional apparatus as an information signal.

  For example, a wiring system schematically shown in FIG. 5 will be described as an example. First, the power line L1 and the information line L2 are pre-wired on the wall surface in the building 200, and the gate device 3 of the switch box 2 provided in the high position HP such as an indoor ceiling surface (see FIG. 7). The basic function module 8d having the hooking blade connecting portion 60 is connected, and the lighting fixture 120 is connected to the basic function module 8d. That is, the information signal transmission device 10a is connected to the basic function module 8d via the power line L1 and the information line L2.

  Then, as shown in the operation flowchart of FIG. 6, the word “Please turn off the power” is uttered to the microphone M1 (step S1), and the verification unit 353 of the voice recognition unit 35h “Please turn off the power”. Is recognized (step S2), the information signal output unit 354 outputs a control command for turning off the luminaire 120 based on the recognition result, and transmits the control command to the information line L2. At this time, the voice recognition unit 35h outputs a voice “turn off the illumination” from the speaker SP in order to notify that the voice signal has been effectively recognized from the output of the microphone M1 (step S3).

  Here, a transmission processing device 110 is connected to the power line L1 and the information line L2, and the transmission processing device 110 relays an information signal from each functional device and responds by referring to an ID or the like included in the information signal. An operation of transmitting an information signal to the functional device is performed. Specifically, in the transmission processing device 110, communication signals are improved by performing multiple channel control (such as time division multiplexing control) on information signals from a plurality of functional devices.

  The control command output from the information signal transmission device 10a to the information line L2 is also relayed by the transmission processing device 110 (step S4) and transmitted to the basic function module 8d (step S5). The basic function module 8d cuts off the power supply to the lighting fixture 120 based on the received control command, and turns off the lighting fixture 120 (step S6).

  When the word “please turn on electricity” is issued to the microphone M1, the control signal for turning on the luminaire 120 is output from the information signal transmission device 10a, and the basic function module 8d receives the received control. Based on the command, power supply to the lighting fixture 120 is started, and the lighting fixture 120 is turned on. Furthermore, dimming control of the lighting fixture 120 can also be performed.

  Note that the control target is not limited to the luminaire, and the operation of an electrical appliance other than the luminaire may be controlled via the functional device, or the operation of the functional device itself may be controlled. For example, when the control target is a television, “Please turn on the television” and “Turn off the television” are registered in advance in the language model storage unit 351 as language models.

  Here, the communication transmission unit 32, the arithmetic processing unit 33, and the I / O interface 34 convert the output of the microphone M1 into a digital signal and transmit it to the functional device via the information line L2, and via the information line L2. An information transmission means for converting the transmitted digital signal into an analog signal and outputting the analog signal to the speaker SP is configured.

  Further, when an alarm signal is transmitted from the basic function module 8 or the extended function module 10 having a sensor function installed in the room where the communication device 10a is arranged, or another room via the information line L2, An alarm sound is emitted from the speaker SP, but the alarm sound output can be canceled by operating the alarm cancel switch SW2.

The information signal transmission function can be added to various functional devices such as a wall switch function and a clock function by connecting the information signal transmission device 10a to the right side of the extended function module 10b. Alternatively, a new extended function module 10b can be connected to the information signal transmission device 10a installed in advance.

  In this case, the power connector 11A ′ and the information connector 11B ′ of the extended function module 10b are installed on the indoor ceiling surface, wall surface, and floor surface and are electrically connected to at least one line of wiring for transmitting power and information signals. The power connector 11A and the information connector 11B of the information signal transmission device 10a correspond to the connected first connection unit, and receive power from the first connection unit to receive information from the first connection unit. This corresponds to a second connection for transmitting and receiving signals. Further, if an extended function module (not shown) having a predetermined function is connected to the right side portion of the information signal transmission device 10a, the power connector 11A ′ and the information connector 11B ′ of the information signal transmission device 10a provide power to the extension function module. And corresponds to a third connection unit for exchanging information signals with the extended function module.

Roads can be secured at the same time, and there is no need for new wiring work, making it excellent in workability. In addition, by using the same information line L2 as the basic function module 8 and the other extended function module 10, it is possible to easily perform the interlock control between the information signal transmission device 10a, the basic function module 8, and the other extended function module 10. It can be performed and has excellent extensibility.

  Further, the function unit 25 of the basic function module 8b constituting the wall switch for turning on / off the lighting fixture generates the operation switch SW3 and operation data of the operation switch SW3 as shown in FIG. The CPU section 25a has a function of generating data to be sent via the I / O interface 24. The operation section of the operation switch SW3 is exposed on the front surface of the decorative cover 8B as shown in FIG.

  Further, the function unit 35 of the extended function module 10b having a clock function generates time data of the timer unit 35f and the timer unit 35f as shown in FIG. 17, and the arithmetic processing unit 33 via the I / O interface 34.

And the like having remote control infrared rays. In addition to audio information, there are interphone master and slave units that have a transmission function for video captured by a surveillance camera or the like, and a video monitoring function.

  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 audio and video is sent to and from the master unit and slave unit based on JT-H232 packets, and one or more can be operated by 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.

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 information signal transmission device 10a), and the end cover 101 is JIS. This has the same shape as the wide handle type switch plate (JIS8316) standardized in the above, and can provide a uniform appearance with the already installed wide handle type switch. 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. 7, the gate device of the switch box 2 provided at 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 8d having a hooking blade connecting portion 60, and the basic function module 8d is connected to, for example, an extended function module 10 provided with a human sensor 61 or the like. Alternatively, the basic function module 8c having only the speaker SP is connected to the gate device 3.

  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. Further, the extended function module 10b having a clock function and the information signal transmission 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 is connected to the gate device 3.

  After the installation work is completed as described above and the system is completed, information signals are exchanged between the corresponding basic function module 8 and the extended function module 10.

  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.

In the present embodiment, as shown in FIG. 18, the function unit 25 of the basic function module 8 includes a speaker SP, a microphone M1, a call switch SW1, an alarm release switch SW2, amplification units 35a and 35b, echo cancellation units 35c and 35d, An information signal transmission device 8a including the voice recognition unit 35h and having the same function as the information signal transmission device 10a of the first embodiment is configured. In addition, the same code | symbol is attached | subjected to the structure similar to Embodiment 1, and description is abbreviate | omitted.

  As in the basic function module 8, the information signal transmission device 8a contains an AC / DC converter 21, a communication transmission unit 22, an arithmetic processing unit 23, an I / O interface 24, and a functional unit 25 in the same manner as the basic function module 8. The external appearance is shown in FIG.

  Also, a plurality of sound holes 8C and insertion holes 8D for exposing the call switch SW1 and the alarm release switch SW2 to the front surface are formed in the front surface of the module body 8A facing the speaker SP and the microphone M1, and the front surface of the decorative cover 8B. It is exposed to.

  As in the first embodiment, when the information signal transmission device 8a recognizes the audio signal from the output of the microphone M1, the information signal transmission device 8a transmits a control command based on the recognition result via the information line L2, and is connected to the information line L2. The operation of the function device and the control target device connected to the function device are controlled.

  Further, the information signal transmission device 8a alone can be used as a basic function module. Further, if necessary, the extended function module 10 is provided on the side portion via the power connectors 9A and 9A ′ and the information connectors 9B and 9B ′. Can be connected. In this case, the connection port 6 including the power path connection port 6 </ b> A and the information path connection port 6 </ b> B of the gate device 3 is installed on the indoor ceiling surface, wall surface, and floor surface, and transmits at least one system wiring. The connector 7 including the connected portion 7A and the connected portion 7B of the information signal transmission device 8a is supplied with power from the first connecting portion, and corresponds to the first connecting portion electrically connected to the first connecting portion. This corresponds to a second connection unit for exchanging information signals with the connection unit. Further, if an extended function module (not shown) having a predetermined function is connected to the right side or the left side of the information signal transmission device 8a, the power supply connectors 9A and 9A 'and the information connectors 9B and 9B' of the information signal transmission device 8a are connected. Corresponds to a third connection unit for supplying power to the extended function module and exchanging information signals with the extended function module.

  Therefore, the information signal transmission device 8a can secure the power path and the information path at the same time by connecting to the power line L1 and the information line L2 that are preliminarily wired in the same way through the gate device 3, and newly construct the wiring work. There is no need to carry out, and it is excellent in workability. Further, by using the same information line L2 as the other basic function module 8 and the extended function module 10, the interlock control between the information signal transmission device 8a and the other basic function module 8 and the extended function module 10 can be easily performed. It can be performed and has excellent extensibility.

(Embodiment 3)
In the first and second embodiments, between the gate device 3, the basic function module 8 (including the information signal transmission device 8a), and the extended function module 10 (including the information signal transmission device 10a), the power path and information by the connector connection The road has been built.

  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 4)
In the first to third embodiments, power (power supply) transmission and information signal delivery are performed in separate systems. However, in this embodiment, the information signal transmission method of the entire system is performed on the power line carrier, thereby The road and information path are shared.

  That is, the leading 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 information signal transmission 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 information signal transmission device 10a) also omits the information connectors 11B and 11B '.

  Then, as shown in FIG. 20, in the information signal transmission 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 PLC signal is received via the PLC modem unit 36. An arithmetic processing unit 33 that performs data processing of an information signal and generates data of an information signal transmitted by power line carrier via the PLC modem unit 36, a functional unit 35, and between the functional unit 35 and the arithmetic processing unit 33 An I / O interface 34 is provided. The arithmetic processing unit 33, the I / O interface 34, and the function unit 35 have the same functions as those in the first to third embodiments.

  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 the configuration of a communication transmission unit or an information connector, so that the arrangement space in the thin module bodies 8A and 10A can be increased.
