Description

  Conventionally, various supply structures for supplying electric power and communication signals to various spaces such as ordinary houses and offices have been proposed. In general, a cable is laid from the switchboard under the floor or inside the wall, and the end of the cable is drawn out in the vicinity of the room. Then, power and communication signals are supplied by connecting a power connector and a signal terminal to the end, and connecting an electric device to the power connector and the signal terminal. However, with the recent diversification of electrical equipment centering on OA equipment, there is an increasing need to use power and communication signals at various positions in the space. A supply structure is desired.

  As one form of such a supply structure with a high degree of freedom, a structure using a so-called flat cable has been proposed. This flat cable is constituted by covering a plurality of a pair of flat wire conductors in a line. This flat cable is thinner than a general cable, and its presence can be almost eliminated by laying this flat cable on the floor and covering it with carpet etc. The degree of freedom can be increased.

  Patent Document 1 discloses a power wiring structure using a plate-like conductor. This structure is configured in layers by sandwiching a third conductor with an insulating film interposed between a first conductor and a second conductor. The first to third conductors are each formed in a narrow plate shape, and by using such a structure, a flat power supply structure can be constructed.

First, [I] the basic concept common to each embodiment was explained, then [II] the specific contents of each embodiment were explained, and [III] finally, a modification to each embodiment was explained. To do. However, the present invention is not limited by these embodiments.

[I] Basic concept common to the embodiments First, the basic concept common to the embodiments will be described. The power communication panel and the power supply communication system according to each embodiment are for supplying power in an arbitrary space such as a general house or an office. This space is not limited to being indoors but may be outdoor, and is not limited to buildings, but includes internal spaces of vehicles such as trains and airplanes. Hereinafter, the three-dimensional space in which the power communication panel or the power supply communication system is used in this way is referred to as a “power supply communication target space”, and power and communication signals are supplied from each plane that partitions the power supply communication target space. A plane for the purpose is referred to as a “power supply communication target plane”, and the other plane is referred to as a “power supply communication non-target plane”. The power supply communication target plane is, for example, the entire area of the floor, wall, or ceiling that partitions the power supply communication target space, or a part of these areas (for example, excluding only the peripheral edge of the four circumferences of the floor surface) Center region).

  In general, the power communication panel is integrally configured by arranging a plurality of conductive plates and insulating layers provided between the plurality of conductive plates so as to overlap each other. Here, the conductive plate is not a narrow conductor as in the prior art but a wide panel body and covers a wide area. Thus, power supply and communication can be easily performed on a wide range of power supply communication target planes. However, it is not necessary to cover all the power supply communication target planes with one power communication panel, and a plurality of power communication panels may be provided side by side and connected to each other. The power communication panel can be formed as a planar shape corresponding to the power supply communication target plane, for example, a square shape or a circular shape.

The support body divides the power supply communication target space from other spaces, and includes an arbitrary structure that can support the power communication panel, and includes, for example, a floor, a wall, or a ceiling. The support includes a planar structure having a flat support surface for supporting the power communication panel, and a support that discontinuously supports the power communication panel via a non-planar structure such as a cross structure. However, the power communication panel does not necessarily have to be supported by the support, and may be used in a self-supporting state, for example.

  In such a configuration, one of the basic features common to each embodiment is that at least one of the plurality of conductive plates arranged on the outer surface of the power communication panel is a ground electrode. A plurality of conductive plates can be connected to a DC power source. For example, in the case of a structure in which the power communication panel is supported by a support that partitions the power supply communication target space, the conductive plate on the side close to the support is the anode, and the conductive plate on the side facing the anode is the ground electrode. In this case, the conductive plate of the grounding electrode is close to the person in the power supply communication target space, and even when the human is in direct contact with the conductive plate directly or through another conductor Since it is possible to prevent energization of the person, it becomes possible to ensure the safety of the person. In addition, you may determine the arrangement | positioning position of the electrically conductive board made into a grounding electrode side on the basis of the side which there exists not only a human body but living things other than humans, such as a pet and livestock.

  Another basic feature common to the embodiments is that a communication signal is supplied in addition to power through the power communication panel. As communication modes, 1) communication by electric field change using an insulating layer (hereinafter referred to as “electric field communication”), 2) communication by magnetic field change using an insulating layer (hereinafter referred to as “magnetic field communication”), 3) conductive plate There are three forms of communication using PLC (hereinafter referred to as “PLC communication”). Hereinafter, specific contents of each embodiment for realizing such a power communication panel and a power feeding communication system will be described.

And the floor constituting panel 7 are substantially flush with each other to form a flat floor surface. The floor constituting panel 7 is a plate-like body formed of, for example, resin or wood.

  Here, as shown in FIG. 3, the power communication panel 10 is connected to a power supply unit 14 and a power extraction unit 15. The power supply unit 14 is a direct current input unit for supplying a direct current to the power communication panel 10, and the power extraction unit 15 acquires the direct current from the power communication panel 10 and supplies it to an arbitrary load 100. DC current output means. For example, when a plurality of power communication panels 10 are arranged in parallel and are connected so that they can be energized with each other, the power supply unit 14 is connected to only one of the power communication panels 10 and other power communication is performed. An arbitrary number of power extraction units 15 corresponding to the load 100 may be provided on the panel 10 to acquire power at a plurality of locations. Alternatively, one set of power supply unit 14 and power extraction unit 15 may be provided for each power communication panel 10. Details of the configurations of the power supply unit 14 and the power extraction unit 15 will be described later.

  In addition, a signal input unit 30 and a signal output unit 31 are connected to the power communication panel 10.

Details of the configuration of the signal input unit 30 and the signal output unit 31 will be described later.

(Configuration of power communication panel 10)
Next, the details of the configuration of each power communication panel 10 will be described. FIG. 4 is a perspective view of the power communication panel 10. The power communication panel 10 is formed in a planar rectangular shape, and includes a plurality (here, two) of conductive plates 11 and 12 and an insulating layer 13 provided between the plurality of conductive plates 11 and 12. Are arranged so as to overlap each other. The conductive plate 11 and the conductive plate 12 are fixed to each other by an arbitrary fixing method such as adhesion, and one power communication panel 10 is configured as a whole.

  Each of the conductive plates 11 and 12 is a plate-like body formed from a conductor such as metal. Specific materials and thicknesses of the conductive plates 11 and 12 can be determined in consideration of desired strength, supplied power, and the like.

  The insulating layer 13 functions as a waveguide for propagating communication signals while preventing the short-circuit between the conductive plates 11 and 12 by insulating each other. The insulating layer 13 is formed in substantially the same planar shape as the conductive plates 11 and 12, and is provided in almost the entire area between the conductive plates 11 and 12. The specific material and thickness of the insulating layer 13 can be determined in consideration of desired insulating properties and waveguide properties. For example, a resin such as polyethylene or vinyl chloride, an inorganic material such as mica or glass fiber, Alternatively, porcelain can be used.

(Configuration of power supply system)
Next, a power supply system for supplying power to the power communication panel 10 and acquiring power from the power communication panel 10 will be described. FIG. 5 is a longitudinal sectional view conceptually showing the power supply system, and FIG. 6 is a perspective view conceptually showing the power supply system.

  First, the power supply unit 14 will be described. The power supply unit 14 includes a DC power supply 14a, an anode side supply line 14b, and a ground electrode side supply line 14c.

  The DC power source 14a is a power source means for supplying DC power to the power communication panel 10, and is configured using, for example, a storage battery or a DC stabilized power source that supplies a commercial AC power source after DC conversion. The DC power supply 14a is installed at an arbitrary position in the vicinity of the power communication panel 10, for example, in the interior of the living room 1 or in a power distribution room adjacent to the living room 1, and the negative electrode thereof is grounded (GND).

  The anode-side supply line 14b supplies power to the conductive plate 12 so that the conductive plate 12 close to the floor 2 as a support body becomes an anode (non-grounded electrode). One end is connected to the side surface and end surface of the conductive plate 12, and the other end is connected to the anode of the DC power supply 14a.

  The ground electrode side supply line 14c is a conductive plate disposed opposite to the conductive plate 12 (a conductive plate disposed outside the power communication panel 10 and disposed at a position closest to the power supply communication target space. ) For supplying electric power to the conductive plate 11 so that 11 becomes a grounding electrode. Specifically, one end of the conductive plate 11 is connected to the side surface or the end surface of the conductive plate 11 and the other end is grounded. .

  Next, the power extraction unit 15 will be described. The power extraction unit 15 is a power extraction unit that extracts electric power from the power communication panel 10 and supplies it to an arbitrary load 100, and includes an anode-side extraction line 15a and a ground electrode-side extraction line 15b.

  The anode-side lead wire 15a connects the anode-side conductive plate 12 and the load 100 to each other, and has one end connected to the inner surface of the conductive plate 12 and the other end connected to the anode of the load 100. ing. More specifically, the finish material 4, the conductive plate 11 on the grounding electrode side, and the insulating layer 13 are formed with lead-out holes 15c communicating with each other, and the anode-side lead-out line is formed through the lead-out hole 15c. 15 a is pulled out to the power supply communication target space side and connected to the load 100.

  The grounding electrode side lead-out line 15b connects the grounding electrode side conductive plate 11 and the load 100 to each other. Specifically, one end of the grounding electrode side lead wire 15b is connected to the upper surface of the grounding electrode side conductive plate 11. The other end is connected to the cathode of the load 100. In practice, a rectifier (not shown) may be provided between the anode side lead wire 15a and the ground electrode side lead wire 15b and the load 100 as necessary. Further, when the load 100 is a DC device, the power extraction unit 15 can be directly connected to the DC device. However, when the load 100 is an AC device, the AC device is connected via a known DC / AC conversion adapter. Can be supplied with an alternating current.

  Next, the function of the power supply system configured as described above will be described with its actions and effects. In this power supply system, the anode of the DC power supply 14a, the anode side supply line 14b, the anode side conductive plate 12, the anode side lead wire 15a, the load 100, the ground electrode side lead wire 15b, the ground electrode side conductive plate 11, the ground A DC circuit that sequentially reaches the pole-side supply line 14 c and the ground plane is formed, and DC power can be supplied to the load 100.

  The reason why the DC power is supplied instead of the AC power is that the power communication panel 10 is equivalent to a huge capacitor on the circuit, so that the impedance that is inversely proportional to the capacity of the capacitor decreases, This is because it is difficult to flow an alternating current. When a direct current is passed through a planar conductor such as the conductive plates 11 and 12, the direct current spreads in a plane along the conductive plates 11 and 12 as shown by arrows in FIG. Therefore, highly efficient power transmission can be performed.

  Further, as described above, the conductive plate 12 that is close to the floor portion 2 that is the support is on the anode side, and the conductive plate 11 that is close to the power supply communication target space is the ground electrode side. Even when a person contacts 11 directly or indirectly through another conductor, it is possible to prevent the person from being energized and to ensure the safety of the human body. In order to further improve the insulation, the insulating sheet 3 in FIG. 1 may be laid between the conductive plate 11 and the finishing material 4.

  Furthermore, since the anode side lead wire 15a is drawn out to the power supply communication target space through the lead hole 15c, the anode side lead wire 15a and the ground electrode side lead wire 15b can be easily provided to the load 100 used on the living room 1 side. Since it can be connected and there is no need to access the conductive plate 12 from the side of the floor portion 2, it is easier to use power.

(Configuration of power supply system-connection structure 1)
Next, a connection structure for connecting a DC power supply or a load 100 to the power communication panel 10 will be described in more detail. FIG. 7 is a longitudinal sectional view showing the power communication panel 10 together with the connection terminals, and FIG. 8 is an enlarged view of a main part of FIG. As shown in FIG. 7, connection terminals 20 are attached to a plurality of positions of the power communication panel 10. In the following description, the connection structure of the load 100 to the power communication panel 10 will be described. However, this structure can be similarly applied to the connection structure of the DC power supply 14 a to the power communication panel 10.

  As shown in FIG. 8, the connection terminal 20 includes a cylindrical external electrode 20a, a rod-shaped internal electrode 20b, and a cylindrical insulating layer 20c that insulates the external electrode 20a and the internal electrode 20b from each other. Concentric combined. The internal electrode 20b is an electrode on the anode side, and has a length that penetrates the conductive plate 11 and the insulating layer 13 on the ground electrode side and reaches the conductive plate 12 on the anode side. The external electrode 20a is an electrode on the ground electrode side, is formed shorter than the internal electrode 20b, and penetrates through the conductive plate 11 together with the internal electrode 20b. The external electrode 20a and the internal electrode 20b are formed in a sharp shape so that the insertion into the conductive plate 11 and the insulating layer 13 is easy.

  In such a configuration, by inserting the connection terminal 20 from above at an arbitrary position where the power in the power communication panel 10 is desired to be obtained, the drawer hole 15c is automatically formed as shown in FIG. The electrode 20b can be brought into contact with the conductive plate 12 as an anode, and the external electrode 20a can be brought into contact with the conductive plate 11 as a ground electrode. Then, the anode electrode lead wire 15a is connected to the internal electrode 20b, and the ground electrode lead wire 15b is connected to the external electrode 20a. The anode electrode lead wire 15a and the ground electrode lead wire 15b are connected as shown in FIG. By connecting to the load 100, power can be supplied to the load 100.

Next, another example of the connection structure will be described. 9 is a longitudinal sectional view showing the power communication panel 10 together with connection terminals according to another example, and FIG. 10 is an enlarged view of the main part of FIG. 9 (FIGS. 9 to 14, FIGS. 16, 18, 21, 28, 29). , 30, 31, and 34, the finishing material 4 is omitted). As shown in FIG. 9, connection holes 21 are formed at a plurality of positions of the power communication panel 10, and connection terminals 22 are attached to all or any part of the connection holes 21.

  As shown in an enlarged view in FIG. 10, the connection terminal 22 is configured by concentrically arranging an external electrode 22a, an internal electrode 22b, and an insulating layer 22c. The external electrode 22a and the internal electrode 22b are not sharp. In addition, an annular contact portion 22d is provided integrally with the external electrode 22a. The connection hole 21 is a cylindrical opening substantially conforming to the outer shape of the connection terminal 22 and is formed so as to reach from the conductive plate 11 on the ground electrode side to the conductive plate 12 on the anode side through the insulating layer 13. . This connection hole 21 can be drilled in advance, for example, in the manufacturing factory of the power communication panel 10.

  In such a configuration, at an arbitrary timing after the power communication panel 10 is laid on the floor 2, the user inserts the connection terminal 22 into the connection hole 21 close to an arbitrary position where power is desired. In the state after the insertion, as shown on the left side of FIG. 10, the contact portion 22d of the external electrode 22a abuts the upper surface of the conductive plate 11 on the ground electrode side, and the tip of the internal electrode 22b is the conductive plate on the anode side. 12, the power can be acquired through the connection terminal 22. When power acquisition is no longer necessary, the connection terminal 22 can be removed from the connection hole 21 as shown on the right side of FIG.

  Here, in the state in which the connection terminal 22 is inserted, in order to more reliably connect the contact portion 22d of the external electrode 22a and the conductive plate 11, the annular conductive seal 23 is contacted as shown in FIG. You may affix so that it may span from the part 22d to the electrically conductive board 11, and it may span. Alternatively, after removing the oxide film on the mutual contact surface between the conductive plate 11 and the contact portion 22d with a paper file or the like, an oxide film adhesion preventing grease or the like is applied to the contact surface to improve and maintain the conductivity. Good.

  Further, the unused connection holes 21 may be closed by a conductive cover 24 as shown in FIG. The conductive cover 24 corresponds to the connection hole cover in the claims, and is formed in a disk shape having substantially the same shape as the opening provided in the conductive plate 11. By closing the connection hole 21 with the conductive cover 24, it is possible to prevent inadvertent contact with the conductive plate 11 on the anode side through the connection hole 21 and to intrude dust or water into the connection hole 21. Further, the upper surface of the power communication panel 10 can be kept flat. It should be noted that a disc-shaped conductive seal 25 extending from the conductive cover 24 to the conductive plate 11 may be attached in order to further ensure the mutual conduction between the conductive plate 11 and the conductive cover 24. If there is no problem even if the conduction in the unused connection hole 21 is cut off, the cover and the seal may be made of a non-conductive material instead of the conductive cover 24 and the conductive seal 25. .

  Alternatively, as shown in FIG. 13, the unused connection hole 21 may be closed using a side-faced T-shaped insulator 26 corresponding to the connection hole 21, and in this case, the connection hole 21 is more reliably closed. be able to. Further, grease for preventing water from entering may be applied around the connection hole 21.

(Configuration of power supply system-connection structure 3)
Next, another example of the connection structure will be described. FIG. 14 is a longitudinal sectional view showing the power communication panel 10 together with connection terminals according to another example. As shown on the left side of FIG. 14, the connection terminal 27 includes an external electrode 27 a, an internal electrode 27 b, and an insulating layer 27 c and is configured in substantially the same manner as the connection terminal 22. Here, a conductive mounting screw 28 extending from the contact portion 27d of the external electrode 27a to the conductive plate 11 is screwed. In this structure, the contact portion 27d can be more reliably brought into contact with the conductive plate 11 by the fastening force of the mounting screw 28, so that the conductive seal 23 as shown in FIG. 11 can be omitted. Alternatively, as shown on the right side of FIG. 14, the entire conductive plate 11 or only a predetermined portion to which the connection terminal 27 is attached may be formed to have a thickness capable of forming the screw hole 27d, and the attachment screw 28 may be screwed through this portion.

(Configuration of communication system-electric field communication)
Next, a communication system for supplying a communication signal to the power communication panel 10 and acquiring a communication signal from the power communication panel 10 will be described. First, a case where electric field communication is performed will be described. FIG. 15 is a longitudinal sectional view conceptually showing the communication system, and FIG. 16 is a longitudinal sectional view of the main part of the communication system.

As shown in FIG. 15, a plurality of electric field probes 32 that function as the signal input unit 30 or the signal output unit 31 are connected to an arbitrary position of the power communication panel 10. As shown in FIG. 16, each electric field probe 32 is configured as a coaxial probe in which an external electrode 32a, an internal electrode 32b, and an insulating layer 32c arranged therebetween are arranged concentrically with each other. Yes. The distal end portion of the electric field probe 32 is inserted into an arbitrary position of the power communication panel 10 from above, thereby penetrating the conductive plate 11 on the ground electrode side and reaching the inside of the insulating layer 13. More specifically, the tip of the electric field probe 32 is the electric field direction of the propagated radio wave (in the case where the radio wave is a TE ₁₀ wave, the direction is perpendicular to the longitudinal direction of the insulating layer, and the direction of the arrow in FIG. 15). And a predetermined dimension L = λ / 4 (where λ is the wavelength of the radio wave).

  In such a configuration, an analog communication signal output from an arbitrary signal supply source (not shown) such as an optical network unit (Optical Network Unit) is converted into an electric field change via any one of the electric field probes 32 as an insulating layer 13. To be supplied. Actually, since it is necessary to propagate the radio wave at a frequency equal to or higher than the cutoff frequency, the radio wave is supplied via a conversion device that performs necessary frequency conversion. Such propagated radio waves are acquired via another electric field probe 32 or a magnetic field probe 33 described later, and input to a predetermined communication device (for example, a personal computer).

(Configuration of communication system-magnetic field communication)
Next, a case where magnetic field communication is performed will be described. FIG. 17 is a longitudinal sectional view conceptually showing the communication system, and FIG. 18 is a longitudinal sectional view of main parts of the communication system. As shown in FIG. 17, a plurality of magnetic field probes 33 that function as the signal input unit 30 or the signal output unit 31 are connected to an arbitrary position of the power communication panel 10. As shown in FIG. 18, each magnetic field probe 33 is configured as an annular so-called loop antenna. The tip of the magnetic field probe 33 is inserted into an arbitrary position of the power communication panel 10 from above, thereby penetrating the conductive plate 11 on the ground electrode side and reaching the inside of the insulating layer 13. Specifically, the tip of the magnetic field probe 33 extends in the magnetic field direction of the propagated radio wave (in the direction along the longitudinal direction of the insulating layer when the radio wave is TE ₁₀ waves, the arrow direction in FIG. 17). The loop surfaces are arranged so as to be orthogonal to each other.

  In such a configuration, a communication signal output from an arbitrary signal supply source (not shown) such as an optical line termination device is supplied to the insulating layer 13 as a magnetic field change through any one of the magnetic field probes 33. This magnetic field change is propagated through the insulating layer 13, acquired through another magnetic field probe 33 or the electric field probe 32 described above, and input to a predetermined communication device.

(Configuration of communication system-PLC communication)
Next, a case where PLC communication is performed will be described. In this PLC communication, the power supply unit 14 also serves as part of the signal input unit 30, and the power extraction unit 15 serves also as part of the signal output unit 31. FIG. 19 is a vertical cross-sectional view of a main part around the power supply unit, and FIG. 20 is a vertical cross-sectional view of a main part around the power extraction unit. As shown in FIG. 19, a modem 34 is connected to the front side of the power supply unit 14 of the power communication panel 10, and a digital communication signal transmitted through the optical fiber 35 is transmitted by the modem 34 to several tens of MHz. Is then supplied to the conductive plates 11 and 12 via the signal lines 36 a and 36 b so as to be superimposed on the direct current and propagated through the conductive plates 11 and 12. In FIG. 19, the waveforms of the DC signal before superposition, the communication signal before superposition, the DC signal after superposition, and the communication signal are shown in a square frame.

  On the other hand, the power extraction unit 15 shown in FIG. 20 includes the connection terminal 20 similar to that in FIG. 8, and signal lines 37 a and 37 b are drawn out from the connection terminal 20. Among these, a signal separation filter 38 is connected to the subsequent stage of the signal line 37a on the anode side. The signal separation filter 38 separates a signal component from a direct current, and is a high-pass filter including a capacitor, for example. The analog communication signal separated by the signal separation filter 38 is converted into a digital communication signal by the modem 39 and output to a communication device (not shown). Although the connection terminal 20 is used here, the connection terminals 22 and 27 in FIGS. 11 and 14 may be used.

(Connection structure of power communication panel 10)
Next, a connection structure for connecting the power communication panels 10 to each other will be described. FIG. 21 is a longitudinal sectional view showing a connection structure and a connection procedure, where (a) is a state in which the power communication panel 10 is attached, (b) is a state before insertion of the connecting portion, and (c) is insertion of the connecting portion. Each subsequent state is shown.

  As shown in FIG. 21A, the two power communication panels 10 connected to each other are processed so that the end portions on the connection side are inclined. More specifically, only the lower conductive plate 12 protrudes toward the counterpart power communication panel 10, and the insulating layer 13 is inclined so as to move away from the counterpart power communication panel 10 as it goes upward. The conductive plate 11 is disposed at a position further away from the counterpart power communication panel 10 than the inclined upper end position of the insulating layer 13. Then, by arranging these two power communication panels 10 in parallel, a space portion 10 a having a substantially V-shaped cross section is formed between the two power communication panels 10.

  In such a state, the lower conductive plate 12 is connected to each other by a predetermined method (for example, welding or pinning or tape fastening using a conductive member) to obtain the state of FIG. Thus, the lower conductive plates 12 can be connected to each other. Then, the connecting portion 29 is inserted into the space portion 10a from above to obtain the state shown in FIG. The connecting portion 29 includes a conductive portion 29a and an insulating portion 29b, and as a whole, has a substantially V-shaped cross section substantially corresponding to the space portion 10a.

  Thereafter, the upper conductive plate 11 and the conductive portion 29a of the connecting portion 29 are connected to each other by an arbitrary method such as welding, or a conductive seal is bridged between the upper conductive plate 11 and the conductive portion 29a. By sticking in this manner, the upper conductive plates 11 are connected to each other through the conductive portion 29a so as to be conductive with each other, and the insulating layer 13 is connected to each other through the insulating portion 29b so that an electric field or a magnetic field can be propagated. This ends the connection. Although only one section is shown in FIG. 21, the present connection structure can be applied over the entire length of the side of the connection side of the power communication panel 10, and the connecting portion 29 is on the side of the connection side. It can be configured as a longitudinal member corresponding to the entire length of the side.

(Effect of Embodiment 1)
According to such a configuration, the planar power supply communication target plane 5 can be formed only by laying the power communication panel 10, and power can be easily supplied to a wide area. In particular, since power supply and communication can be performed by arranging the flat power communication panel 10 side by side, a continuous flat floor surface can be formed, and the convenience and design of the power supply communication target space can be achieved. There is no loss.

  In addition, since the conductive plate 12 close to the floor 2 is used as an anode and the conductive plate 11 close to the power supply communication target space is set as a ground electrode side, a person directly connects to the conductive plate 11 or through another conductor. Even when indirect contact occurs, it is possible to prevent energization of a person and to ensure the safety of the human body.

  Furthermore, power can be supplied and acquired by attaching the connection terminals 20, 22, and 27 to any position of the power communication panel 10, so that power can be supplied to a wide range of power supply communication target planes 5 by any route. The line can be easily constructed, and the convenience of using power can be improved.

  Furthermore, the electric field probe 32 and the magnetic field probe 33 can be attached to an arbitrary position of the power communication panel 10, and the insulating layer 13 can function as a waveguide to propagate the electric field or magnetic field. Alternatively, a communication signal can be superimposed on the current and propagated through the conductive plates 11 and 12. Therefore, a communication line can be easily constructed on a wide range of power supply communication target planes 5 by an arbitrary route, the convenience of communication can be improved, and the power communication panel 10 can also be used as a communication panel.

It is fixed at. The power communication panel 40 is composed of conductive plates 41 and 42 and an insulating layer 43 disposed therebetween.

  In such a structure, when a construction worker or an electric worker enters above the ceiling 8, there is a possibility that the power communication panel 40 may be touched from between the field edge 8a and the field edge receiver 8b. For this reason, in this Embodiment 2, while making the electroconductive board 41 of the side close | similar to the ceiling 8 which is a support body into a grounding electrode side, while eliminating the danger of an electric shock of an operator etc., the electric power communication panel 40 is provided. An insulating sheet 3 is laid on the upper surface of the slab to further enhance its safety.

  On the other hand, the conductive plate 42 on the lower side of the ceiling 8 is set as the anode side. This is because the ceiling 8 is provided at a height at which a person cannot easily contact the conductive plate 42. It is assumed that there is little possibility of people touching. The finishing material 4 is affixed to the lower surface of the conductive plate 42. However, the insulating sheet 3 is laid between the conductive plate 42 and the finishing material 4, or the finishing material 4 itself has an insulating property. May be. A load 100 such as a lighting device is connected to the ceiling 8.

One end of the ground electrode side lead wire 15 b is connected to the lower surface of the conductive plate 41, and the other end is connected to the cathode of the load 100. Specifically, the conductive plate 42 and the insulating layer 43 on the anode side are formed with lead-out holes 15c communicating with each other, and the ground electrode-side lead wire 15b is connected to the power communication target space side through the lead-out hole 15c. And is connected to the load 100. However, when the load 100 is installed on the upper side of the ceiling 8, as in the first embodiment, the anode-side supply line 14b and the ground-electrode-side supply line 14c are drawn out toward the conductive plate on the ground-electrode side. May be.

(Configuration of communication system)
The communication system for the power communication panel can be configured in the same manner as in the first embodiment. For example, by inserting the electric field probe 32 in FIG. 16 or the magnetic field probe 33 in FIG. 18 into an arbitrary position of the power communication panel 40, A communication signal can be propagated as an electric field change or a magnetic field change through the insulating layer 43. Alternatively, as in FIGS. 19 and 20, a communication signal may be superimposed on a direct current via the conductive plates 41 and 42 and transmitted by the PLC method. If at least a part of both surfaces of the power communication panel 40 is exposed to the outside as in the present embodiment, the electric field probe 32 and the magnetic field probe 33 may be inserted from the conductive plate 41 on the ground electrode side. If the risk of electric shock or the like can be avoided, it may be inserted from the conductive plate 42 on the anode side, and communication signals can be input and output from any surface of the power communication panel 40.

(Effect of Embodiment 2)
In this way, the conductive plate 41 on the support side may be the ground electrode side, and the other conductive plate 42 may be the anode side. In this case, the safety of the human body on the support side is ensured, and the opposite of the support body. Electric power can be supplied to the load 100 on the side.

[Embodiment 3]
Next, a third embodiment of the present invention will be described. The third embodiment is a form in which the power communication panel is configured in a semi-sealed type.

And an insulating layer 55 disposed between the conductive plate 52 and the conductive plate 53. Further, an insulating layer 56 is disposed on the side of the conductive plate 53 as necessary, and the conductive plate 53 is completely surrounded by these insulating layers 54 to 56 and insulated from the outside, whereby the conductive plate 53 The end portion 53 is not exposed to the end face of the power supply panel 50. As shown in FIG. 25, the conductive plates 53 of a plurality of adjacent power communication panels 50 may be connected to each other by using a connection structure described later.

(Configuration of power supply system)
Next, the power supply system will be described. FIG. 26 is a longitudinal sectional view conceptually showing the power supply system. The ground electrode side supply line 14c of the power supply unit 14 supplies power to the conductive plates 51 and 52 so that the pair of conductive plates 51 and 52 arranged outside the power communication panel 50 become ground electrodes. Specifically, one end thereof is connected to the upper surfaces and end faces of the conductive plates 51 and 52, and the other end is connected to the ground plane. The anode-side supply line 14b supplies power to the conductive plate 53 so that the conductive plate 53 surrounded by the insulating layers 54 and 55 becomes an anode. Specifically, one end of the conductive plate 53 is connected to the conductive plate 53. The upper end and the end face are connected, and the other end is connected to the anode of the DC power supply 14a. When the anode side supply line 14b is connected to the end face of the conductive plate 53, a through hole may be formed in the insulating layer 56, and the anode side supply line 14b may be drawn through the through hole.

  Further, the anode side lead wire 15a of the power extraction portion 15 connects the anode side conductive plate 53 and the load 100 to each other, and one end thereof is connected to the upper surface of the conductive plate 53 and the other end is connected. It is connected to the anode of the load 100. Specifically, the conductive plate 51 and the insulating layer 54 on the ground electrode side are formed with a lead hole 15c that communicates with each other and reaches the conductive plate 53 on the anode side, and the lead hole 15c passes through the lead hole 15c. Thus, the anode lead-out line 15a is drawn out to the power supply communication target space side and connected to the load 100. The ground electrode side lead-out line 15b connects the conductive plate 51 on the ground electrode side and the load 100 to each other.

In this connection structure, connection terminals 20, 22, and 27 similar to those shown in FIGS. 8, 11, and 14 in the first embodiment can be used. The structures corresponding to FIGS. 8, 11 and 14 are shown in FIGS. 27 to 29, respectively. However, in this embodiment, the external electrodes 20a, 22a, and 27a of the connection terminals 20, 22, and 27 are connected to the conductive plate 51 on the ground electrode side, and the internal electrodes 20b, 22b, and 27b are connected to the conductive plate 51 on the ground electrode side.

The upper conductive plate 51 is inclined away from the panel 50, and the upper conductive plate 51 is disposed further away from the counterpart power communication panel 50 than the inclined upper end position of the insulating layer 54. Then, by arranging these two power communication panels 50 in parallel, a space portion 50 a having a substantially V-shaped cross section is formed between the two power communication panels 50.
In this state, the end portion of the conductive plate 53 is exposed to the outside. For example, a power communication panel 50 in which the side of the conductive plate 53 is surrounded by an insulating layer 56 is prepared, and a connecting surface of the power communication panel 50 is prepared. May be exposed so that the end of the conductive plate 53 is exposed. Alternatively, the power communication panel 50 in which the insulating layer 56 is omitted and the end portion of the conductive plate 53 is exposed from the beginning may be used.

  In such a state, the lower conductive plate 52 is connected to each other by a predetermined method (for example, welding or pinning or tape fastening using a conductive member) to obtain the state of FIG. As a result, the lower conductive plates 52 can be electrically connected to each other. Then, the connecting portion 57 is inserted into the space portion 50a from above to obtain the state shown in FIG. The connecting portion 57 is formed by sequentially superposing the conductive portion 57a, the insulating portion 57b, the conductive portion 57c, and the insulating portion 57d as shown in the figure, and as a whole, has a substantially V-shaped cross section substantially corresponding to the space 50a.
