DETAILED DESCRIPTION OF THE INVENTION
=== Network connection method ===
1A and 1B show a device configuration of a communication network connection system in an embodiment of the present invention. In this embodiment, it is constituted by a rosette 10 which is attached to a ceiling and serves as a wiring fixture for supplying power to a lighting fixture, and a network adapter device (hereinafter referred to as an adapter) 30 which operates by being supplied with power from the rosette 10. In this example, a well-known power line communication (PLC) network is assumed as a communication network. In this figure, (A) is a perspective view when the rosette 10 and the adapter 30 are viewed from below, and (B) is a perspective view when the adapter 30 is viewed from above.
[0016]
The rosette 10 is generally the same as a commercially available one, and includes a hooked rosette type power outlet (hereinafter referred to as a primary outlet) 11 for supplying power to a lighting fixture from a power line laid on the back of the ceiling.
[0017]
The adapter 30 is provided with a closet-type plug (hereinafter referred to as a plug) 31 that is hooked substantially at the center of the upper surface of the substantially disk-shaped case, and the plug 31 is hooked on the primary outlet 11 of the rosette 10, thereby Operates with power. In addition, it has a PLC modem function, and communicates with information processing equipment and home appliances participating in the network by radio signals, and mediates data communication by the radio signals and data communication by the PLC.
[0018]
A rosette outlet (hereinafter referred to as a secondary outlet) 32 is disposed at the approximate center of the lower surface. If a lighting fixture having a rosette plug, for example, is hooked on the secondary outlet 32, the primary fixture is placed on the lighting fixture. Electric power from the outlet 11 is supplied via the adapter 30.
[0019]
=== Basic configuration and operation of the adapter ===
FIG. 2 is a functional block diagram of the adapter 30. The power supply unit 33 generates power for various circuits in the adapter 30 from household power supplied via the primary outlet 11 and the plug 32. The power supply unit 33 also includes a filter for removing noise mixed in the power line 1. Further, by providing a path 34 that is directly connected to the secondary outlet 31 from the plug 32, the power from the rosette 10 is directly supplied to the luminaire attached to the adapter 30.
[0020]
The adapter control unit 35 is a microcomputer including a CPU, a RAM, and a ROM, and controls each peripheral component unit to control the adapter 30. The wireless interface unit 36 receives a wireless signal of a predetermined standard, and transfers the code in the received signal to the adapter control unit 35. In this embodiment, infrared rays are used as radio signals. The transmission / reception control unit 37 extracts digital data from the modulation signal output according to the infrared signal received by the light receiving element 38 and transfers the digital data to the adapter control unit 35, or modulates the digital data supplied from the adapter control unit 35 and modulates the digital data. The LED drive circuit 39 is driven by the signal to emit an infrared signal from the LED 40.
[0021]
Specifically, the adapter control unit 35 converts the digital data received from the wireless interface unit 36 into data that can be interpreted by the PLC modem 41, and gives this to the PLC modem 41. The PLC modem 41 multiplexes this data on the power line 1, The multiplexed signal is transmitted onto the power line (PLC network) 1 through the plug 32 and the primary outlet 11 of the rosette 10.
[0022]
Further, the PLC modem 41 extracts the data multiplexed on the power line 1 and gives it to the adapter controller 35. The adapter control unit 35 converts this data into data in a format conforming to a predetermined standard, and gives this to the transmission / reception control unit 37 of the wireless interface unit 36. The transmission / reception control unit 37 modulates this data and provides this modulation signal to the LED drive circuit 39. The LED drive circuit 39 drives the LED 40 with this modulation signal to send out an infrared signal.
[0023]
=== Network configuration ===
FIG. 3 illustrates a home communication network configuration that employs the network connection method of the present invention. Here, a home automation system in which home appliances 7 in each room 2 in the house are remotely controlled by operating the STB 3 and information from the security sensor 8 is collected and processed by the STB 3 is taken as an example. .
[0024]
The STB 3 is a computer having the television receiver 4 as a display, and functions as a PLC modem, and also has a function of communicating with an external information processing device via a public communication network such as an internet or telephone line. And the code | cord | chord for remote control operation of various household appliances 7 is memorize | stored. For example, the user tries to turn on the home appliance 7 in a certain room 2 by directly operating the STB 3 or by operating it from a computer outside the home via a public communication network. The STB 3 sends a remote control code multiplexed signal corresponding to the operation signal to the adapter 3 in the designated room 2 on the power line 1. The corresponding adapter 3 receives data including this code addressed to itself and transmits an infrared signal including the code. Thereby, the power supply of the designated home appliance 7 in this room 2 is turned on.
[0025]
In addition, home appliances in one room 2 can be operated from another room 2. For example, an operation for causing the home appliance to perform a predetermined operation using a remote control device of the home appliance 7 in a room 2 is performed. An infrared signal from the remote control device is converted into data of a predetermined format by the adapter 3 in the room and is transmitted onto the power line 1. When the STB 3 receives this data, it transfers this data to all the adapters 3 in the home. The adapter 3 in each room converts this data into an infrared signal and sends it out, and the corresponding home appliance 7 operates in accordance with the remote control operation. Of course, if the adapter 3 is provided with a control circuit for supplying and disconnecting power to the secondary outlet 31 in accordance with instructions from the STB 3, the lighting fixture 9 that is fed from the outlet 31 is controlled to be turned on / off. You can also.
[0026]
A general-purpose personal computer (hereinafter referred to as PC) can be used instead of a dedicated device such as STB. Then, an application that realizes the same function as that of the STB may be installed on the PC, and various interface cards corresponding to network communication inside and outside the house may be mounted.
[0027]
=== About the radio interface ===
In the above embodiment, infrared rays are used as a radio signal. For example, a wireless transmission method using radio waves such as a specific power-saving radio, Bluetooth (registered trademark), or a wireless LAN compliant with the Ethernet (registered trademark) standard may be used. Of course, the wireless interface unit may support a plurality of wireless communication methods.
[0028]
=== About the switch for lighting ===
Generally, a primary outlet of a rosette to which a lighting device is attached is energized / disconnected in conjunction with a lighting switch (hereinafter referred to as a wall switch) on the wall of the same room. As a result, the luminaire supplied with power from the rosette is turned on / off. Therefore, if the wall switch is turned off, power is not supplied to the adapter 30 and data communication via the network is disabled in the room. Of course, it is also possible to energize the adapter 30 with the wall switch closed. The lighting device can be turned on / off by a switch (such as a pull-down switch) of the lighting device itself. However, the adapter 30 itself is not interlocked with the wall switch operation, and if the lighting apparatus supplied with power through the adapter 30 is interlocked with the wall switch operation, even if the wall switch is accidentally turned off, data communication may be interrupted there. Disappear.
[0029]
FIG. 4 is a schematic diagram of the power supply wiring of the rosette 100 in the network connection method interlocking with the conventional wall switch. Conventionally, the primary outlet 11 of the rosette 10 and the switch 102 are inserted in series on a path 101 around the power source 100. FIG. 5 shows an example of a connection method that is not interlocked with the switch operation. In this network connection method, the primary outlet 11 of the rosette 10 is directly connected to the power source 100. Wirings (105, 106) extending from the terminals (103, 104) of the wall switch 102 are guided to the rosette 10. In this example, wiring (105, 106) extending from the two terminals (103, 104) of the switch 102 is guided into the adapter 30 via the rosette 10. The ends of the wiring (105, 106) from the switch 102 guided to the rosette 10 side are appropriately guided into the adapter 30 by providing connectors (12, 43) on both the rosette 10 and the adapter 30. do it.
[0030]
The adapter 30 includes a relay 41 and a control circuit 40 for energizing the coil 42 of the relay 41 in response to the operation of closing the switch 102. The control circuit 40 of the present embodiment is a DC power source generated by the power source unit 33, and this power source, the switch 102, and the relay coil 42 are connected in series. The contacts (43, 44) of the relay 41 are inserted into one of the paths 34 from the plug 32 to the secondary outlet 31 in the adapter 30. When the control circuit 40 energizes the coil 42 of the relay 41 in conjunction with the closing operation of the switch 102, the contacts (43, 44) of the relay 41 are closed and power is supplied to the secondary outlet 31. When the switch 102 is opened, the power supply to the coil 42 is stopped, the contacts (43, 44) are released, and the power supply to the secondary outlet 31 is cut off. Therefore, the lighting fixture fed from the secondary outlet 31 can be turned on / off in conjunction with the operation of the wall switch 102, and the adapter 30 can be operated without being interlocked with the operation of the wall switch 103. .
[0031]
FIG. 6 is an example of a rosette employed in a network connection method corresponding to this wall switch, and FIG. 6 (A) shows a plan view from the bottom. Also, (B) and (C) show the outline of the internal wiring of the rosette 10 by side perspective views. In the illustrated rosette 10, when the adapter 30 is not connected and the lighting fixture is directly attached to the rosette 10, the internal wiring path can be switched so that the lighting on / off operation is interlocked with the opening / closing operation of the wall switch. It can be done.
[0032]
On the lower surface, a primary outlet 11 and a terminal (switch wiring guide terminal) 13 for guiding a wiring end extending from the contact (103, 104) of the wall switch 102 are arranged. On the ceiling side surface (upper surface) of the rosette 10, terminals a to f (14 to 19) appropriately connected to the internal wiring are disposed. Terminals a14 and f19 are connected to paths (20, 24) that are short-circuited to either electrode of the primary outlet 11, respectively. Terminals b15 and c16 are connected to a path (21, 22) that is short-circuited to the switch wiring guide terminal 13. The terminal d17 and the terminal e18 are connected to a path 23 that is internally short-circuited.
[0033]
Here, when the adapter 30 is connected, the wires (101a, 101b) from both poles of the household power supply 100 are connected to the terminals a14 and f19, respectively, and the wires from the two contacts (103, 104) of the switch 102 are connected. (105, 106) are connected to the terminal 15 and the terminal 16, respectively. Thereby, the wiring (103, 104) from the switch 102 is directly short-circuited with the switch wiring guide terminal 13 on the lower surface (B).
[0034]
When the adapter 30 is not attached, it is necessary to link the opening / closing operation of the wall switch 102 with the energization / disconnection operation of the primary outlet 11. In this case, the wiring 101a from one pole of the power supply 100 is connected to the terminal a14, and the wiring 101b from the other pole is connected to the terminal d17. The end of the wiring 105 guided from one contact 103 of the wall switch 102 is connected to the terminal e18 connected to the terminal d17 via the internal short-circuit path 23. Then, the end of the wiring 106 from the other terminal 104 of the wall switch 102 is connected to the terminal f19. As a result, the same wiring state as the wiring diagram shown in FIG. 5 is obtained. Note that, by changing the wiring state to the terminals a to f (14 to 19) as shown here, the configuration is not limited to the configuration in which the power supply interlocking / non-interlocking of the primary outlet with respect to the operation of the wall switch 102 is switched. The wiring may be fixedly connected to a predetermined terminal, and a switch for switching the internal wiring path may be provided in the rosette.
[0035]
Note that all or a part of the circuit elements including the control circuit and the relay may be incorporated on the rosette side, the ceiling, or the like. Of course, the circuit configuration itself is not limited to the one using the relay shown here, and any circuit configuration may be used as long as the power supply / disconnection operation to the primary outlet can be performed in conjunction with the switch operation. .
[0036]
=== Connection to other network ===
The network connection system of the present invention is not limited to the PLC, and can be applied to various networks if a network wiring compliant with other standards such as Ethernet (registered trademark) is installed. Then, the rosette is provided with a physical port for connecting to the network, and the adapter is connected to a connector for connecting to the port, and data communication by wireless signals and data communication conforming to the network are mediated. The circuit for this may be mounted.
[0037]
For example, if the communication network is Ethernet using a 100BASE-T standard twisted pair cable, an RJ45 standard jack is provided on the upper surface of the rosette, and another jack is provided on the lower surface or side surface so that there is an internal space between the terminals of the two jacks. Connect by wiring. On the other hand, a similar jack is provided at an appropriate place on the case surface of the adapter. Then, a jack on the upper surface of the rosette and a network connection device such as a network hub or router may be connected by a LAN cable, and another jack provided on the lower surface or side surface of the rosette and a jack of the adapter may be connected by a LAN cable.
[0038]
=== General versatility by unit replacement ===
There are various types of networks laid in the house, such as PLC and Ethernet. There are also various wireless communication standards. For example, even with the same infrared signal, there is a remote control signal for operating a general home appliance, and there is an IrDA. As for radio waves, there are specific power-saving radios and Bluetooth. Of course, even in the same home, there is a possibility that these networks and radio signals are properly used depending on the device of the communication partner. Thus, if each adapter is prepared according to a complicated network configuration, it lacks versatility. It is also difficult to reduce manufacturing costs. Therefore, if at least the part that depends on the network form is unitized and the unit can be detachably replaced with the basic part that does not depend on the network form such as the adapter controller and power supply circuit, the versatility will be improved and the basic part We can expect cost reduction by sharing.
[0039]
FIG. 7 shows an example of the unit replacement type adapter, and (A) to (C) show an overhead perspective view, a top plan view (partially exploded view), and a partly enlarged view, respectively. A plug (not shown) and a secondary outlet 31 are arranged opposite to the front and back surfaces, and a power supply unit 51, a network communication adapter unit 54, a wireless interface are provided around a core unit 50 incorporating an adapter control unit. Peripheral units such as the units (52, 53) are detachably mounted. In this example, two units, a wireless interface unit 52 for specific power-saving wireless communication and a wireless interface unit 53 for infrared communication, are mounted. Each peripheral unit (51 to 54) and the core unit 50 are structured to be attached and detached by a projection 55 and a hole 56 having claws that engage with each other. Adjacent peripheral units are fixed with screws 58 via joints 57. The joint 57 itself is fixed to the ceiling with a screw 59. Accordingly, the peripheral units (51 to 54) and the adapter itself are prevented from dropping / falling due to their own weight.
[0040]
The circuit connection between the peripheral units (51 to 54) and the core unit 50 may be provided with a connector structure (not shown) connected to the contact end face 60. When circuit connection between adjacent peripheral units is necessary, a terminal (not shown) is arranged at a predetermined position on the contact end surface 61 so that the terminals come into contact with each other in the combined state. That's fine. When connecting the minimum necessary units, as shown in FIG. 8, a hollow unit 62 may be attached to adjust the outer shape of the adapter 30. In the example shown in FIG. 8, it is assumed that the power supply unit is built in the core unit 50 or the peripheral units (52, 54).
[0041]
=== Device configuration of communication network ===
In the above embodiment, the embodiment of the connection method of the present invention has been described by taking home automation as an example. Of course, the network connection method of the present invention can be applied to a communication network mainly composed of a PC such as a LAN. The PC only needs to be configured to communicate with the adapter by a predetermined wireless signal. For wireless data communication, a short-range wireless communication standard such as IrDA or Bluetooth, or a wireless LAN (IEEE802.11b standard, etc.) can be adopted.
[0042]
【The invention's effect】
According to the communication network connection system of the present invention, the time and labor involved in wiring work and the wiring itself can be reduced as much as possible. Therefore, the cost for network construction can be reduced, and the aesthetics of the home is not impaired.
[0043]
The lighting power supply wiring device mounted on the ceiling serves as a connection port to the network, and data communication can be performed with a device participating in the network by radio signals. Therefore, it is possible to flexibly cope with the arrangement and installation of various devices and furniture that participate in the network.
[0044]
Since data communication and data communication via the network are mediated by wireless signals, general-purpose home appliances operated by remote control signals such as infrared rays can also participate in a home communication network. Therefore, a home automation system can be easily constructed without preparing a special device corresponding to the network. The cost of purchasing network-compatible equipment can also be reduced.
