Description

  The present invention relates to a power communication floor structure for supplying power and communication signals, and a supply panel and a functional module for constructing the power communication floor structure.

  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.

For example, when there is a possibility of using power and communication signals in a large number of positions in a wide room, when using a flat cable or the power wiring structure of Patent Document 1, a large number of these must be laid. It was lacking in practicality, such as requiring a lot of labor for laying and connecting.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. 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 floor structure according to each embodiment is 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 to which the power communication floor structure is applied is referred to as a “power supply communication target space”, and power and communication signals are supplied among the planes that define the power supply communication target space. The plane is referred to as “power supply communication target plane”, and the other plane is referred to as “power supply communication non-target plane”. The power supply communication target plane is, for example, the entire area of the floor that divides the power supply communication target space, or a part of these areas (for example, the center area excluding only the four peripheral edges of the floor surface). .

  In general, the supply 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 a single supply panel, and a plurality of supply panels may be provided side by side and connected to each other. The supply 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.

  This supply panel is supported by a support. The support body divides the power supply communication target space from other spaces, includes an arbitrary structure that can support the supply panel, and is, for example, a floor portion. Examples of the support include a flat structure having a flat support surface for supporting the supply panel, and a support that discontinuously supports the supply panel via a non-planar structure, such as a crosspiece structure.

  In such a configuration, one of the basic features common to the respective embodiments is that the plurality of conductive plates are connected to a direct current so that at least one of the plurality of conductive plates of the supply panel serves as a ground electrode. It is in the point connected to the power supply. For example, in the case of a structure in which the supply 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 this 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 electric power through a supply 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”). By performing communication in these various forms individually or in combination with each other, it is possible to realize communication in a wide range of power supply communication target planes via the supply panel.

  Furthermore, another basic feature common to the embodiments is that a plurality of functional modules are arranged in parallel on the upper surface of the supply panel. This functional module is roughly divided into two types based on the function. The first is a first functional module having only the function of configuring the floor, and the second is a function of inputting or outputting power or a communication signal connected to the supply panel in addition to the function of configuring the floor. It is the 2nd functional module which has. Further, the second functional module includes a power module that transmits and receives power, a communication module that transmits and receives communication signals, a sensor module that detects a detection target and outputs a signal related to the detection result, and receives a control signal input Actuator module that performs an operation according to the control signal to the inside or the outside of the second functional module, receives a communication signal and performs information processing based on the communication signal, or a communication signal related to the result of the information processing Are classified into information processing modules. Furthermore, the power module is divided into a power supply module that only supplies power and a power distribution module that only acquires power and supplies power to a load. The communication module is divided into a wired communication module that inputs and outputs a communication signal by wire and a wireless communication module that inputs and outputs a communication signal by wireless. However, when it is not necessary to distinguish between them, the various modules are “functional modules”, the power supply modules and the power distribution modules are “power modules”, and the wired communication modules and the wireless communication modules are “communication modules”. And are collectively referred to. By arranging such modules alone or in any combination on the top surface of the supply panel, the various functions of each module can be linked to the power transmission / reception function and communication signal transmission / reception function of the supply panel. The various functions of each module can be realized in a wide range of power supply communication target planes.

  The floor portion 2 is a support body that supports the supply panel 10 and is configured as, for example, a reinforced concrete floor slab, and is a planar structure whose upper surface is a smooth horizontal surface. An insulating sheet 3 is laid on substantially the entire upper surface of the floor portion 2, and the floor portion 2 and the supply panel 10 are electrically insulated from each other by the insulating sheet 3.

Each supply panel 10 is laid on the upper surface of the floor 2 and is connected to another adjacent supply panel 10. On the other hand, in the power supply communication non-target plane 6, the floor 2 may be simply exposed, but here, by arranging the floor constituting panel 7 having substantially the same thickness as the supply panel 10, the supply panel 10 and the floor are arranged. A flat floor surface is formed by making the upper surface of the component panel 7 substantially flush with each other. The floor constituting panel 7 is a plate-like body formed of, for example, resin or wood.

  FIG. 4 is a side view conceptually showing the structure for the power supply function and the communication function. In the power supply communication non-target plane 6, only the first functional modules 51 are arranged in parallel to constitute a substantially flat floor surface. Since the power supply communication non-target plane 6 does not require power supply or communication, a floor structure panel 7 that is a floor material may be laid instead of the supply panel 10. On the other hand, in the power supply communication target plane 5, a plurality of second functional modules 52 are arranged in parallel on the upper surfaces of the plurality of supply panels 10, and a substantially flat floor surface substantially flush with the power supply communication non-target plane 6 is provided.

For example, various loads 100 (robot RB in FIGS. 1 and 4) are arranged on the upper surface of the second functional module 52, and power supply and communication can be performed for this apparatus. In the present embodiment, an example in which the supply panel 10 and the functional module 50 are configured with the same width is illustrated, but the supply panel 10 and the functional module 50 may be configured with any different width. Although omitted here, a finishing material such as a floor tile or a tile carpet may be laid on the upper surface of the functional module 50.

(Configuration of supply panel 10)
Next, details of the configuration of each supply panel 10 will be described. FIG. 5 is a perspective view of the supply panel 10. The supply 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. They 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 bonding, and a single supply 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.

(Function module-first function module)
Next, details of the configuration of the first functional module 51 will be described. FIG. 6 is a diagram conceptually showing the configuration of the first functional module 51. The first functional module 51 is configured in the same manner as a known OA floor, for example, and has a substantially square planar floor surface component plate 51a and a plurality of support legs 51b that support the floor surface component plate 51a. And it is comprised by the substantially rectangular parallelepiped shape as a whole. These floor surface constituent plates 51a and support legs 51b have sufficient support strength to support equipment and furniture installed above the first functional module 51, and are configured using, for example, light metal. . The support leg 51b can be finely adjusted in length in the vertical direction by a known mechanism, and the floor surface constituting plate 51a can be leveled by finely adjusting the length of each support leg 51b. In each drawing other than FIG. 6, the support leg 51b is omitted, and the functional module is shown as a simple rectangular parallelepiped. Further, the support leg 51b can be actually omitted.

(Function module-second function module)
Next, details of the configuration of the second functional module 52 will be described. The second functional module 52 is basically provided with a floor surface configuration plate 51 a and support legs 51 b in the same manner as the first functional module 51, so that the second functional module 52 is installed above the second functional module 52. Sufficient support strength to support installed equipment and furniture. The following modules belonging to the second functional module 52 are obtained by adding configurations necessary for performing various functions to the basic structure of the second functional module 52. Hereinafter, each of these second functional modules 52 will be described.

(Function module-second function module-power supply module or power distribution module-basic concept of power supply structure)
First, the power supply module 53 or the power distribution module 54 in the second functional module 52 will be described. First, the basic concept of the power supply structure will be described. FIG. 7 is a longitudinal sectional view conceptually showing the power supply structure, and FIG. 8 is a perspective view conceptually showing the power supply structure.

  Here, as shown in FIG. 7, the power supply module 53 incorporates the power supply unit 14. The power supply unit 14 is a direct current input means for supplying a direct current to the supply panel 10, and includes a direct current power source 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 supply 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 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 supply panel 10 and disposed at a position closest to the power supply communication target space). Electric power is supplied to the conductive plate 11 so that 11 becomes a ground electrode. Specifically, one end of the conductive plate 11 is connected to a side surface or an end surface of the conductive plate 11, and the other end is grounded.

  Further, as shown in FIG. 7, the power extraction unit 15 is connected to the inside of the power distribution module 54. The power extraction unit 15 is a direct current output unit for acquiring a direct current from the supply panel 10 and supplying the direct current to an arbitrary load 100, and includes an anode side extraction line 15a and a ground electrode side extraction line 15b. Yes. 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 conductive plate 11 on the ground electrode side and the insulating layer 13 have lead-out holes 15c communicating with each other, and the anode-side lead-out line 15a communicates with the power via the lead-out hole 15c. It is pulled out to the 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.

  For example, when a plurality of supply 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 supply panels 10 and the other supply panels 10 are connected. On the other hand, an arbitrary number of power extraction units 15 corresponding to the load 100 may be provided 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 supply panel 10. Actually, the power supply unit 14 is provided in the power supply module 53, and the power extraction unit 15 is provided in the power distribution module 54. Details thereof will be described later.

  Next, the function of the power supply structure configured as described above will be described with its actions and effects. In this power supply structure, the anode of the DC power source 14a, the anode side supply line 14b, the anode side conductive plate 12, the anode side lead wire 15a, the load 100, the grounding electrode side lead wire 15b, the grounding electrode side conductive plate 11, the grounding 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 supply panel 10 is equivalent to a huge capacitor in terms of the circuit. Therefore, when the capacitance of the capacitor increases, the impedance inversely proportional to the capacitance decreases. This is because it is difficult to flow current. Further, 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. Moreover, since the conductive plate 11 on the side close to the functional module 50 is the ground electrode side as described above, even when a person contacts the conductive plate 11 directly or indirectly through another conductor. Therefore, it is possible to prevent energization of the person 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 functional module 50. 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.

(Function Module-Second Function Module-Power Module-Power Supply Module Configuration 1)
Next, a specific configuration of the power supply module 53 will be described. FIG. 9 is a diagram illustrating a connection structure between the power supply module 53 and the supply panel 10. As shown in FIG. 9, the power supply module 53 includes the power supply unit 14 and the connection terminal 20 described above.

  FIG. 10 is an enlarged view around the connection terminal. The connection terminal 20 is configured by concentrically combining 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. ing. 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. The anode electrode supply line 14b is connected to the internal electrode 20b, and the ground electrode supply line 14c is connected to the external electrode 20a.

  As shown on the right side of FIG. 9, the connection terminal 20 is disposed so that the sharp end thereof protrudes downward from the lower surface of the power supply module 53. In such a configuration, when the power supply module 53 is placed at an arbitrary position in the supply panel 10, the connection terminal 20 is automatically inserted into the supply panel 10 from above as shown on the left side of FIG. Are formed automatically, and the internal electrode 20b can be brought into contact with the conductive plate 12 of the anode and the external electrode 20a can be brought into contact with the conductive plate 11 of the ground electrode. Therefore, DC power can be supplied to the supply panel 10. Note that an AC / DC converter may be built in the power supply module 53 so that AC power taken from outside is converted into DC by the AC / DC converter and then supplied to the supply panel 10.

(Function Module-Second Function Module-Power Module-Power Supply Module Configuration 2)
Next, another example of the connection structure of the power supply module 53 will be described. FIG. 11 is a diagram illustrating a connection structure between the power supply module 53 including the connection terminal 22 and the supply panel 10 according to another example. FIG. 12 is an enlarged view around the connection terminal. As shown in FIG. 11, connection holes 21 are formed at a plurality of positions on the supply panel 10, and connection terminals 22 are attached to all or arbitrary portions of the connection holes 21.

  As shown in an enlarged view in FIG. 12, the connection terminal 22 is formed 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 plant of the supply panel 10.

  In such a configuration, the power supply module 53 so that the user inserts the connection terminal 22 into the connection hole 21 near the arbitrary position where the user wants to acquire power at an arbitrary timing after the supply panel 10 is laid on the floor 2. Place. In the state after the arrangement, as shown on the left side of FIG. 12, the contact portion 22d of the external electrode 22a is in contact with 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 where 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. In order to attach the conductive seal 23, for example, all or part of the floor surface constituting plate 51a constituting the power supply module 53 can be opened and closed, and the connection terminal 22 is viewed from above in the state where the floor surface constituting plate 51a is opened. May be made accessible (the same applies to fixing of the mounting screw 28 described later). Further, after removing the oxide film on the 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 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. In addition, the upper surface of the supply 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. 15, the unused connection hole 21 may be blocked using a side surface T-shaped insulator 26 corresponding to the connection hole 21, and in this case, the connection hole 21 is more reliably blocked. be able to. Further, grease for preventing water from entering may be applied around the connection hole 21.

(Function Module-Second Function Module-Power Module-Power Supply Module Configuration 3)
Next, another example of the connection structure of the power supply module 53 will be described. FIG. 16 is a longitudinal sectional view showing the supply panel 10 together with connection terminals 27 according to another example. As shown on the left side of FIG. 16, the connection terminal 27 includes an external electrode 27 a, an internal electrode 27 b, and an insulating layer 27 c, and is configured with substantially the same structure 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. 13 can be omitted. Alternatively, as shown on the right side of FIG. 16, the entire conductive plate 11 or only a predetermined portion to which the connection terminal 27 is attached may have a thickness that allows the screw hole 27d to be formed, and the mounting screw 28 may be screwed through this portion.

(Function module-second function module-distribution module 1)
Next, the power distribution module 54 in the second functional module 52 will be described. As shown in FIG. 17, the power distribution module 54 includes the above-described power extraction unit 15 and the connection terminal 20, and is configured so as to expose the power supply terminal 54 a on the upper surface. Since the connection terminal 20 can be configured in the same manner as in FIG. 10, the description thereof is omitted. The anode electrode lead wire 15a is connected to the internal electrode 20b of the connection terminal 20, and the ground electrode lead wire 15b is connected to the external electrode 20a. The power supply terminal 54a is a connection terminal for taking out power from the power distribution module 54 and supplying it to an arbitrary load 100, and is provided substantially flush with the upper surface of the floor surface constituting plate 51a. The power supply terminal 54a includes, for example, a pair of an anode terminal and a cathode terminal in the same manner as a known plug socket. The anode terminal has an anode lead wire 15a and the cathode terminal has a ground electrode lead wire 15b. Are connected to each other. Therefore, the DC power can be supplied to the load 100 by inserting the outlet plug of the power cord of the load 100 into the power supply terminal. Note that the power distribution module 54 may be supplied with a DC / AC converter built-in and converted from DC to AC.

(Function module-second function module-distribution module 2)
Next, another example of the connection structure of the power distribution module 54 will be described. FIG. 18 is a longitudinal sectional view showing the power distribution module 54 together with the supply panel 10, and FIG. 19 is a plan view of the power distribution module 54. Here, the power supply terminal 54 a is formed as a plurality of metal plates exposed on the upper surface of the power distribution module 54. In such a configuration, for example, a flat plate-like power acquisition terminal is disposed on the bottom surface of a leg of a self-propelled device such as a robot, and the robot is self-propelled on the upper surface of the power distribution module 54 to supply power. The terminal 54a and the power acquisition terminal may be automatically brought into contact with each other to supply power. In this case, since the power supply can be continued even when the robot moves on the upper surface of the power distribution module 54, the degree of freedom of movement of the robot can be increased.

(Function module-second function module-wired communication module-electric field communication)
Next, the wired communication module 55 in the second functional module 52 will be described. In particular, a wired communication module 55 for performing electric field communication will be described. 20 is a longitudinal sectional view conceptually showing the communication system, and FIG. 21 is a longitudinal sectional view of an essential part of FIG. The wired communication module 55 includes the electric field probe 32 and the signal lines 36a and 36b, and is provided with the signal connection terminal 55a exposed on the upper surface.

As shown in FIG. 21, the 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. . The distal end portion of the electric field probe 32 is inserted into an arbitrary position of the supply 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, it is a direction orthogonal to the longitudinal direction of the insulating layer 13, and the arrow direction in FIG. ) 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 supplied to the insulating layer 13 as an electric field change through the electric field probe 32. 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 a propagated radio wave is acquired as a voltage change via the electric field probe 32 of another wired communication module 55 and input to a predetermined communication device (for example, a personal computer).

  The electric field probe 32 is disposed so that its sharp end protrudes downward from the lower surface of the wired communication module 55. In such a configuration, when the wired communication module 55 is placed at an arbitrary position on the supply panel 10, the electric field probe 32 is automatically inserted into the supply panel 10 from above and a communication signal is input to the supply panel 10. be able to.

  Any number of wired communication modules 55 configured in this way can be provided for the supply panel 10. For example, a communication signal input from one wired communication module 55 can be transmitted to a plurality of wired communication modules 55. Communication signals output from each of them or input from a plurality of wired communication modules 55 can be output from one wired communication module 55. When communicating a plurality of communication signals, for example, the communication signals can be identified from each other by performing communication according to a known communication protocol or adding identification information to the communication signals.

(Function module-second function module-wired communication module-magnetic field communication)
Next, a wired communication module for performing magnetic field communication will be described. FIG. 22 is a longitudinal sectional view conceptually showing the wired communication module, and FIG. 23 is a longitudinal sectional view of an essential part of FIG. In each of these drawings, the wired communication module 55 includes a magnetic field probe 33 instead of the electric field probe 32. As shown in FIG. 23, the 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 supply 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 is the direction of the magnetic field of the propagated radio wave (in the case where the radio wave is a TE ₁₀ wave, the direction is along the longitudinal direction of the insulating layer 13 and the arrow direction in FIG. 22). 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 terminator is supplied to the insulating layer 13 through the magnetic field probe 33 as a magnetic field change. This magnetic field change is propagated through the insulating layer 13, acquired as a voltage change via the magnetic field probe 33 of another wired communication module 55, and input to a predetermined communication device. The relationship between the magnetic field probe 33 and the wired communication module 55 is the same as in the case of the electric field communication. By placing the wired communication module 55 on the supply panel 10, the electric field probe 32 is placed on the supply panel 10 from above. A communication signal can be input to the supply panel 10 by being automatically inserted.

(Function module-second function module-wired communication module-PLC communication)
Next, the wired communication module 55 for performing PLC communication will be described. FIG. 24 is a longitudinal sectional view of an essential part around the wired communication module for supplying power. The wired communication module 55 for supplying power has a built-in modem 55b, and after the digital communication signal transmitted through the optical fiber 35 is converted into a high frequency analog communication signal of several tens of MHz by the modem 55b. By being supplied to the conductive plates 11 and 12 through the signal lines 37 a and 37 b and the connection terminals 20 configured in the same manner as in FIG. 10, they are superimposed on the direct current and propagated through the conductive plates 11 and 12. . In FIG. 24, the DC signal before superposition, the communication signal before superposition, the DC signal after superposition, and the waveform of the communication signal are shown in a square frame.

  On the other hand, FIG. 25 is a vertical cross-sectional view of the main part around the wired communication module for power extraction. As shown in FIG. 25, the wired communication module 55 for power extraction is configured to include a connection terminal 20 similar to that in FIG. 10, and signal lines 37 a and 37 b are drawn from the connection terminal 20. Among these, the signal separation filter 55d is connected to the subsequent stage of the signal line 37a on the anode side. The signal separation filter 55d is for separating a signal component from a direct current and is, for example, a high pass filter including a capacitor. The analog communication signal separated by the signal separation filter 55d is converted into a digital communication signal by the modem 55c and output to a communication device (not shown).

  24 and 25 show an example in which the connection terminal 20 is used, but the connection terminals 22 and 27 in FIGS. 13 and 16 may be used. The relationship between the connection terminal 20 and the wired communication module 55 is the same as in the case of the electric field communication. By placing the wired communication module 55 on the supply panel 10, the connection terminal 20 is connected to the supply panel 10 from above. A communication signal can be input to the supply panel 10 by being automatically inserted.

(Function module-second function module-wireless communication module)
Next, the wireless communication module 56 will be described. However, unless otherwise specified, the configuration is the same as that of the wired communication module 55 described above, and substantially the same components are denoted by the same reference numerals or names as necessary, and description thereof is omitted. As conceptually shown in FIG. 26, the wireless communication module includes the above-described electric field probe 30, signal lines 36a and 36b, and a wireless transceiver 56a.

  Here, the wireless transceiver 56a is a wireless transmission / reception means for wirelessly transmitting / receiving a communication signal to / from an arbitrary wireless device, and includes, for example, a loop antenna and a signal processing unit (not shown). In such a configuration, a communication signal input via the electric field probe 30 is wirelessly transmitted via the wireless transceiver 56a, or a signal received via the wireless transceiver 56a is supplied via the electric field probe 30. It is output to the panel 10. Therefore, by arranging the load 100 such as a computer or a robot apparatus provided with a communication unit that performs wireless communication near the upper position of the wireless communication module 56, wireless communication can be performed between them.

(Function module-second function module-sensor module)
Next, the sensor module 57 will be described. However, unless otherwise specified, the configuration is the same as that of the wired communication module 55 described above, and substantially the same components are denoted by the same reference numerals or names as necessary, and description thereof is omitted. As conceptually shown in FIG. 27, the sensor module 57 includes the above-described electric field probe 30 and signal lines 36a and 36b, and includes the sensor 57a so as to be exposed on the upper surface.

  Here, the sensor 57a is a detection unit that detects a predetermined detection target and outputs a detection signal. For example, a known magnetic sensor, thermal sensor, infrared sensor, capacitance sensor, or the like can be used. In such a configuration, the detection signal output from the sensor 57 a is output to the supply panel 10 via the electric field probe 32. Therefore, the detection state of the detection target in the vicinity of the upper part of the sensor module 57 can be transmitted to the far side via the supply panel 10, and the state of the power supply communication target space can be remotely monitored.

(Function module-second function module-actuator module)
Next, the actuator module 58 will be described. However, unless otherwise specified, the configuration is the same as that of the power distribution module 54 described above. About the same components, the same reference numerals or names are given as necessary, and the description thereof is omitted. As conceptually shown in FIG. 28, the actuator module 58 includes an actuator 58a in addition to the connection terminal 20 described above.

  The actuator 58a is driven by a power source supplied via the connection terminal 20 and performs a predetermined operation. For example, the actuator 58a is driven by controlling air pressure or hydraulic pressure via various motors or electromagnetic valves. It can be configured as a drive mechanism, and it is possible to drive an arbitrary object disposed inside or outside the actuator module 58.

(Function module-second function module-processing module)
Next, the processing module 59 will be described. However, unless otherwise specified, the configuration is the same as that of the wired communication module 55 described above, and substantially the same components are denoted by the same reference numerals or names as necessary, and description thereof is omitted. As conceptually shown in FIG. 29, the processing module 59 includes a processing unit 59a in addition to the electric field probe 32, the signal lines 36a and 36b, and the connection terminal 55a described above.

  The processing unit 59a includes, for example, a CPU (Central Processing Unit) 59b and a memory 59c, and a program that is loaded into the memory 59c as needed and is interpreted and executed by the CPU. Information processing based on a predetermined algorithm is performed on the received signal, and the result is output to the outside through the connection terminal 55a. Here, the result of information processing is output to the outside, but information input from the outside is processed and output to the supply panel 10 via the electric field probe 32 or the magnetic field probe 33, or the supply panel 10 It is also possible to process the information input from, and output the result to the supply panel 10 without outputting it to the outside.

(Connection structure of supply panel 10)
Next, a connection structure for connecting the supply panels 10 to each other will be described. FIG. 30 is a longitudinal sectional view showing a connection structure and a connection procedure, where (a) is a state in which the supply panel 10 is attached, (b) is a state before insertion of the connecting portion, and (c) is after insertion of the connecting portion. Each state is shown.

  As shown in FIG. 30 (a), the two supply panels 10 connected to each other are processed so that the ends on the connection side are inclined. More specifically, only the lower conductive plate 12 protrudes toward the counterpart supply panel 10, and the insulating layer 13 is inclined so as to move away from the counterpart supply panel 10 as it goes upward, and the upper conductive plate 12. The plate 11 is arranged at a position further away from the counterpart supply panel 10 than the inclined upper end position of the insulating layer 13. Then, by arranging these two supply panels 10 in parallel, a space portion 10 a having a substantially V-shaped cross section is formed between the two supply panels 10.

  In such a state, the lower conductive plate 12 is connected to each other by a predetermined method (for example, welding, pinning or tape fastening using a conductive member), and the state shown in FIG. Thus, the lower conductive plates 12 can be connected to each other. And the connection part 29 is inserted in the space part 10a from the top, and it is set as the state of FIG.30 (c). 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. 30, this connection structure can be applied over the entire length of the connection side of the supply panel 10, and the connecting portion 29 is connected to the side of the connection side. It can comprise as a longitudinal member corresponding to the full length.

(Effect of Embodiment 1)
According to such a configuration, the planar power supply communication target plane 5 can be formed only by laying the supply panel 10, and power can be easily supplied to a wide area. In particular, since the power supply and communication can be performed by arranging the flat supply 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 are impaired. There is nothing. In addition, since the conductive plate 12 adjacent to the functional module 50 is on the ground electrode side, even when a person contacts the conductive plate 11 directly or indirectly through another conductor, it prevents electricity from flowing to the person. Can ensure the safety of the human body. Furthermore, since power can be supplied and acquired by attaching the connection terminals 20, 22, and 27 to any position of the supply panel 10, the power supply line can be connected to a wide range of power supply communication target planes 5 through any path. Can be easily constructed, and the convenience of power use can be improved. Furthermore, the electric field probe 32 and the magnetic field probe 33 can be attached to an arbitrary position of the supply 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 supply panel 10 can be used as a communication panel.

  In particular, by arranging the first functional module 51 or the second functional module 52 in parallel, a flat floor surface can be configured, and like the normal floor surface, equipment, furniture, etc. are provided on the upper surface. Therefore, the convenience of the power supply communication target space can be maintained.

In addition, the power supply or communication platform can be constructed as a planar area by laying the supply panel 10, and the power supply or communication can be performed by adding the second functional module 52 to an arbitrary position on the upper surface. It can be easily realized, and the feasibility and flexibility of power supply or communication in a wide range can be dramatically increased.
Specifically, by arranging the power supply module 53 and the power distribution module 54 on the supply panel 10, the power supplied by the power supply can be supplied to the supply panel 10, or the power supplied via the supply panel 10. Can be supplied to the load 100, so that a power supply structure can be easily constructed.
Further, by arranging the wired communication module 55 on the supply panel 10, the communication signal output from the communication device is relayed to the supply panel 10, or the communication signal supplied via the supply panel 10 is transmitted to the communication device. Since it can be relayed, a communication structure can be easily constructed.
In particular, by arranging the wireless communication module 56 on the supply panel 10, a communication signal can be input or output wirelessly to the supply panel 10, so that a wireless communication structure can be easily constructed and wired communication can be performed. Compared with this, the convenience of communication can be further enhanced.
In addition, by arranging the sensor module 57 on the supply panel 10, a communication signal related to the detection result of a predetermined detection target can be output to the supply panel 10, so that the presence or absence of the detection target in the power supply communication target space can be grasped at a remote position. It becomes possible to remotely monitor the state of the power supply communication target space.
In addition, by arranging the actuator module 58 on the supply panel 10, various operations can be performed inside or outside the actuator module 58. For example, any object placed above the actuator module 58 can be used. Can be driven.
Further, by arranging the information processing module 59 on the supply panel 10, various information processing can be performed, so that various controls according to the processing result can be performed.

(Configuration of supply panel)
FIG. 31 is a longitudinal sectional view of the power feeding communication system according to the second embodiment. As shown in FIG. 31, the power supply communication system is configured by arranging a plurality of supply panels 70 in parallel on the upper surface of the floor 2 and the insulating sheet 3 configured in the same manner as in the first embodiment.

  Each supply panel 70 is disposed between the pair of conductive plates 71 and 72, the conductive plate 73 disposed between the pair of conductive plates 71 and 72, and the conductive plate 71 and the conductive plate 73. The insulating layer 74 includes an insulating layer 75 disposed between the conductive plate 72 and the conductive plate 73. In addition, an insulating layer 76 is disposed on the side of the conductive plate 73, and the conductive plate 73 is completely surrounded and insulated from the outside by the insulating layers 74 to 76, so that the end portion of the conductive plate 73 is provided. Is not exposed to the end face of the power supply panel 70. As shown in FIG. 32, the conductive plates 73 of a plurality of adjacent supply panels 70 may be connected to each other by using a connection structure described later.

(Configuration of power communication system)
Next, a power communication system will be described. FIG. 33 is a longitudinal sectional view conceptually showing the power supply structure. The ground electrode-side supply line 14c of the power supply unit 14 supplies power to the conductive plates 71 and 72 so that the pair of conductive plates 71 and 72 arranged outside the supply panel 70 become ground electrodes. Specifically, one end thereof is connected to the upper surfaces and end faces of the conductive plates 71 and 72, and the other end is connected to the ground plane. The anode-side supply line 14 b supplies power to the conductive plate 73 so that the conductive plate 73 surrounded by the insulating layers 74 and 75 becomes an anode. Specifically, one end of the conductive plate 73 is connected to the conductive plate 73. 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 73, a through hole may be formed in the insulating layer 76, and the anode side supply line 14b may be drawn through the through hole.

  Further, the anode lead-out line 15a of the power lead-out 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 73, and the other end is connected. It is connected to the anode of the load 100. Specifically, the conductive plate 71 and the insulating layer 74 on the ground electrode side are formed with a lead hole 15c that communicates with each other and reaches the conductive plate 73 on the anode side. 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 71 on the ground electrode side and the load 100 to each other. Specifically, one end thereof is connected to the upper surface of the conductive plate 71 on the ground electrode side. The other end is connected to the cathode of the load 100.

  Next, a connection structure for connecting the load 100 to the supply panel 70 will be described in detail. In this connection structure, connection terminals 20, 22, and 27 similar to those shown in FIGS. 10, 13, and 16 in the first embodiment can be used. Structures corresponding to these FIGS. 10, 13 and 16 are shown in FIGS. However, in the present embodiment, the external electrodes 20a, 22a, and 27a of the connection terminals 20, 22, and 27 are connected to the conductive plate 71 on the ground electrode side, and the internal electrodes 20b, 22b, and 27b are connected to the conductive plate 71 on the ground electrode side. In addition, it is connected to the conductive plate 73 on the anode side through a lead hole 15 c that penetrates the insulating layer 74.

(Communication structure)
As the communication structure, the same electric field probe, magnetic field probe, and PLC communication structure as those shown in FIGS. The structures corresponding to FIGS. 21, 23 to 25 are shown in FIGS. 37 to 40, respectively. Here, an example in which the electric field probe 32 and the magnetic field probe 33 penetrate the conductive plate 71 and are inserted into the insulating layer 74 is shown, but the supply panel 70 can be accessed from the lower side. In such a case (for example, when the supply panel 70 is supported by the crosspiece structure as in the second embodiment), the conductive plate 72 may be inserted into the insulating layer 75. When performing PLC communication, a conductive plate 72 on the ground electrode side and a conductive plate 73 on the anode side may be used.

(Connection structure between supply panels 70)
Next, a connection structure for connecting the supply panels 70 to each other will be described. 41A and 41B are longitudinal sectional views showing a connection structure and a connection procedure, in which FIG. 41A is a state in which the supply panel 70 is attached, FIG. 41B is a state before insertion of the connecting portion, and FIG. 41C is after insertion of the connecting portion. Each state is shown.

  As shown in FIG. 41A, the two supply panels 70 connected to each other are processed so that the end portions on the connection side are inclined. More specifically, only the lower conductive plate 72 protrudes toward the counterpart supply panel 70, and each of the insulating layer 75, the conductive plate 73, and the insulating layer 74 moves upward and the counterpart supply panel 70. The upper conductive plate 71 is disposed at a position further away from the other supply panel 70 than the inclined upper end position of the insulating layer 74. Then, by arranging these two supply panels 70 side by side, a space portion 70 a having a substantially V-shaped cross section is formed between the two supply panels 70. In this state, the end of the conductive plate 73 is exposed to the outside.
