  Hereinafter, an arbitrary distribution device among the plurality of distribution devices is referred to as “distribution device 3”, and an arbitrary communication terminal among the plurality of communication terminals is referred to as “communication terminal 5”. In the following description, “position information” indicates arbitrary position information among the plurality of position information, and “apparatus identification information” indicates arbitrary apparatus identification information among the plurality of apparatus identification information. The device identification information includes a MAC (Media Access Control) address.

  On the other hand, each communication terminal (5a, 5b, 5c, 5d, 5e, 5f, 5g, 5h) has terminal identification information (Aa, Ab, Ac, Ad, Ae, Af, Ag, Ah) for identifying each. Is remembered. In the following description, “terminal identification information” indicates arbitrary terminal identification information among a plurality of terminal identification information. The terminal identification information includes a MAC address. Each communication terminal 5, when receiving the position information from the distribution device 3, transmits the position information together with its own terminal identification information to the distribution device 3.

  In addition, each distribution device 3 is built in an electric device (2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h) installed on the ceiling β of the indoor α or attached to each of these external devices. ing. Hereinafter, an arbitrary electric device among the plurality of electric devices is referred to as “electric device 2”.

  Each electric device 2 supplies power to each distribution device 3. Among these, the electric equipment 2a is a fluorescent lamp type LED (Light Emitting Diode) lighting fixture. The electric device 2b is a ventilation fan. The electric device 2c is an access point for a wireless local area network (LAN). The electric device 2d is a speaker. The electric device 2e is an emergency light. The electric device 2f is a fire alarm or a smoke alarm. The electric device 2g is a surveillance camera. The electric device 2h is an air conditioner.

For example, in addition to the example of the electric device 2, a general fluorescent or incandescent lighting fixture that is not an LED, a security sensor that detects an intruder from the outside, and the like can be given.

  On the other hand, each communication terminal 5 is attached to the outside of the management object (4a, 4b, 4c, 4d, 4e) whose position is managed by the position management device 9, respectively.

  Among these, the management target 4a is a bag. The management object 4b is a table. The managed object 4c is a projector. The managed object 4d is a video conference terminal. The management target 4e is an MFP (Multi Function Product) including a copy function. The management object 4f is a broom.

Furthermore, the management target 4h is a mobile phone such as a smartphone, and since the function of the communication terminal 5 is installed in the mobile phone, it is also the communication terminal 5h in this case. Hereinafter, an arbitrary management object among the plurality of management objects will be referred to as “management object 4”.

  Next, an outline of an example of a location information management method using the location information management system 1 will be described.

  In one embodiment, for example, the distribution device 3a installed on the ceiling β of the indoor α distributes position information Xa indicating the position where the distribution device 3a is installed by wireless communication. Thereby, the communication terminal 5a receives the position information Xa. Next, the communication terminal 5a transmits terminal identification information Aa and position information Xa for identifying the communication terminal 5a to the distribution device 3a by wireless communication. In this case, the communication terminal 5a sends back the position information Xa received from the distribution device 3a to the distribution device 3a.

  Thereby, the distribution apparatus 3a receives the terminal identification information Aa and the position information Xa. Next, the distribution device 3a transmits the terminal identification information Aa and the position information Xa to the gateway 7 by wireless communication. Then, the gateway 7 transmits the terminal identification information Aa and the position information Xa to the position management device 9 via the LAN 8e. The location management device 9 manages the terminal identification information Aa and the location information Xa, so that the administrator of the location management device 9 can grasp the location of the communication terminal 5a (managed object 4a) in the indoor α.

  Further, among the communication terminals 5, particularly the communication terminals (5g, 5h), as shown in FIG. 1, in the outdoor γ, a radio signal (time information, orbit information, etc.) is transmitted from a GPS (Global Positioning System) satellite 999. And the position on the earth can be calculated. Then, the communication terminals (5g, 5h) use a mobile communication system such as 3G (3rd Generation), 4G (4th generation), etc., to make a base station 8a, a mobile communication network 8b, a gateway 8c, the Internet 8d, and a LAN 8e. It is also possible to transmit terminal identification information (Ag, Ah) and position information (Xg, Xh) for identifying the communication terminals (5g, 5h) to the position management device 9 via.

  A communication network 8 is constructed by the base station 8a, the mobile communication network 8b, the gateway 8c, the Internet 8d, the LAN 8e, and the gateway 7. In addition, in order to measure the latitude and longitude on the earth, at least three GPS satellites are required (four are required when the altitude is included), but for simplicity, one GPS satellite is shown in FIG. Show.

  FIG. 2 is a location information management system 1 according to an embodiment. FIG. 2 shows lighting devices 100, 102, 104, and 106 as an electrical device 2 having a distribution device 3, wireless terminals 120, 122, and 124 as a communication terminal 5, a management device 140, a management server 160, a lighting device and a wireless terminal A network 180 and a network 190 including the management device. Here, the network 180 is a wireless network managed by the management device 140. FIG. 3 shows the luminaires 100, 102, 104, and 106, the wireless terminals 120, 122, and 124, and the management device 140 that constitute the wireless network in FIG.

  The luminaires 100, 102, 104, and 106 are attached to, for example, a ceiling of a room, and position information (hereinafter referred to as “position information”) such as background information, the number of floors of a building, and a building number related to the attached position. This is transmitted wirelessly continuously or intermittently. The lighting fixtures 100, 102, 104, and 106 transmit the position information held by each of the lighting fixtures 100, 102, 104, and 106 to a predetermined range using a wireless signal. The predetermined range is determined by the signal strength of the radio signal used. The luminaire is arranged so as to cover a region that is a position management target, and is configured so that the respective regions do not overlap. Or even if it is a case where it overlaps, in the side which receives a positional information, it is comprised so that any one lighting fixture can be determined based on the intensity | strength of a received radio wave. In the example of FIG. 2, a conical dotted line shown below each lighting fixture represents a predetermined range. As a communication method for transmitting position information, for example, a ground complementary signal (Indoor Messaging System; IMES) can be used.

  The wireless terminals 120, 122, and 124 can receive wireless signals transmitted by the nearest lighting device among the lighting devices 100, 102, 104, and 106. In the example of FIG. 2, each wireless terminal is attached to a rectangular parallelepiped management target that is a target whose position is to be managed. The wireless terminals 120, 122, and 124 are terminals that can transmit radio waves themselves, such as active tags. Hereinafter, the wireless terminal 120 will be described.

  As described above, in the position information management system 1 according to the embodiment, the wireless terminal can transmit the identification information and the position information to the management server using power sufficient to communicate with the nearest lighting fixture. In addition, since the lighting apparatus is provided with a communication function with the wireless terminal and the management server, it is not necessary to install a new infrastructure for supplying power necessary for the communication function, and the introduction cost can be reduced. .

  Note that the position information of the luminaire may be provided through the network 180. This eliminates the need for transmission means for transmitting position information such as IMES.

  Further, the wireless terminal may transmit the identification information and the position information to the management apparatus 140 when the management apparatus is present in the vicinity of the lighting fixture that has transmitted the position information. Thereby, identification information and position information can be transmitted to the management server by the shortest path.

  Further, the management server function may be integrated into the management server. This eliminates the need for a separate management device.

  The wireless terminal may be a wireless terminal having a function equivalent to an active tag, such as a smartphone, PDA, PC, or smart meter. As a result, it is possible to manage the position information of the existing wireless terminal without attaching a tag.

  Further, in addition to the above-described position information, information for specifying a finer position, such as information representing a section in the room, may be included. As a result, finer location management is possible.

  The location management target may be a person. Thereby, the location of a person can be managed by the system 1.

  The network 180 may be configured using short-range wireless communication such as Bluetooth (registered trademark) LE, ANT, Z-Wave, or the like. This makes it possible to manage position information of various wireless terminals.

  The network 190 may include a plurality of types of networks such as the Internet. This makes it possible to manage the location information of the wireless terminal regardless of the physical location between the network 180 and the management server 160.

Further, a transmission control module 163, a communication control module 164, and the like are further provided inside the base unit 161 (see FIG. 9). The transmission control module 163 is a substrate having a circuit that controls transmission of a position signal by a position signal transmitter 158 described later. The communication control module 164 is a substrate having a circuit that controls communication between a wireless communication device 159 described later and a wireless terminal or a management server.

  As shown in FIG. 7, the base part 161 is attached to a flat part 172 parallel to the XY plane with a substrate 157 provided with a plurality of LED elements 156, a position signal transmitter 158, and a wireless communicator 159 constituting the light source. It has been. The light source cover part 162 has a semicircular cross section and is attached to the base part 161 so as to cover the LED elements 156 provided on the substrate 157. The LED element 156 on the substrate 157 emits light to the outside through the light source cover part 162 when power is supplied from the power supply module 171 provided inside the base part 161.

  FIG. 8 is a diagram illustrating the internal configuration of the illumination device 150 according to the embodiment of the present invention, and is a diagram of the state where the light source cover 162 is removed from the illumination device 150 as viewed from the + Z side (lower side). As shown in FIG. 8, a plurality of LED elements 156 are arranged in the X-axis direction on the surface side of the substrate 157 on the + Z side. A position signal transmitter 158 and a wireless communicator 159 are provided on the + Z side surface of the substrate 157.

  Further, as shown in FIG. 9, a power supply module 171, a transmission control module 163, a communication control module 164, and the like are provided on the −Z side (upper) surface of the substrate 157 inside the base portion 161. .

  The position signal transmitter 158 is a device including an antenna capable of transmitting and receiving radio waves conforming to, for example, the IEEE 802.15.4 standard. The position signal transmitter 158 transmits a positioning signal such as IMES (Indoor Messaging System), and the predetermined lighting device 150 or the like is transmitted. A position signal representing the position information is transmitted to the wireless terminal.

  The wireless communication device 159 is a device including an antenna capable of transmitting and receiving radio waves conforming to IEEE802.15.4 standard, for example. The wireless communication device 159 receives the identification information and position information of the wireless terminal from the wireless terminal that has received the position signal, and transmits the received identification information and position information to the management server that manages the position of the wireless terminal. To do.

  Here, as the wireless communication device 159, as shown in FIGS. 8 and 9, a monopole antenna extending from the substrate 157 in the Z-axis direction is employed. In this case, the wireless communication device 159 is provided in a substantially vertical direction with respect to the substrate 157 so that the light of the LED element 156 is not obstructed. Note that the wireless communication device 159 may be a helical antenna that extends spirally from the substrate 157 in the Z-axis direction. Also in this case, the wireless communication device 159 is provided so as to extend in a substantially vertical direction with respect to the substrate 157, so that the light of the LED element 156 is not obstructed. Note that the wireless communication device 159 is insulated from the position signal transmitter 158.

  As shown in FIG. 10, the position signal transmitter 158 has a period in which a plurality of right-hand / left-handed composite lines (hereinafter also referred to as “CRLH transmission lines”) are periodically arranged in the X-axis direction with a lattice constant a. It has an array structure (right-hand / left-handed composite line metamaterial structure).

  “Right / left-handed composite line” is a line that combines a right-handed line and a left-handed line, and is well known to exhibit dispersion characteristics as shown in FIGS. 11 (A) and 11 (B). ing.

  In FIGS. 11A and 11B, the horizontal axis is the phase constant, the vertical axis is the angular frequency, the horizontal axis is 0 point, and the π / a point is called the Γ point and the X point, respectively. Yes.

  As can be seen from FIG. 11 (A), the right / left-handed composite line has a left-handed propagation mode in which the group velocity and the phase velocity are different from each other on the low frequency side of the frequency axis (ω axis) on the high frequency side. There is a right-handed propagation mode in which the group velocity and the phase velocity have the same sign.

  Further, even when the phase velocity approaches 0, the group velocity takes a finite value. A stop band exists on the lower side than the X point frequency in the left-handed mode and on the higher side than the X point frequency in the right-handed mode. In general, as shown in FIG. 11A, a band gap which is a non-propagating region exists between the right-handed mode and the left-handed mode.

  Here, in FIG. 11A, when LL / CL = LR / CR, the band gap disappears. At this time, the right-hand / left-handed composite line exhibits a dispersion characteristic as shown in FIG. In FIG. 11B, the group velocity at the Γ point does not become zero, and energy is transmitted through the line. In a region where the phase velocity in the transmission line is higher than the high speed, radiation can be generated in a direction different from the transmission direction by providing a slit or the like. This phenomenon is called a leakage radiation phenomenon.

As shown in FIG. 12A, the CRLH transmission line that satisfies LL / CL = LR / CR has a left-handed mode and a right-handed mode in the fast wave region. The radiation angle θ from the line is related to the phase constant β of the propagation wave in the line, the wave number k _{0 in} vacuum, and θ = sin ⁻¹ (β / k ₀ ).

  Radiation occurs in the backward direction (−θ direction) in the left-handed band and in the forward direction (+ θ direction) in the right-handed band. Such a CRLH transmission line antenna (leakage wave antenna) is capable of continuous and wide-angle beam scanning (see FIG. 12B).

  Here, the position signal transmitter 158 is mounted on the surface of the substrate 157 on the + Z side.

  Specifically, as shown in FIG. 8, the position signal transmitter 158 includes a periodic arrangement structure (right hand / right hand) in which a plurality of unit cells UC1 each functioning as the CRLH transmission line are periodically arranged in the X-axis direction. (Left-handed composite line metamaterial structure).

  As an example, the unit cell UC1 has a stacked structure as shown in FIG. 13 (A) to FIG. 13 (C). FIG. 13A is a plan view of the unit cell UC1, FIG. 13B is a cross-sectional view taken along the line P-P in FIG. 13A, and FIG. 13C is the QQ in FIG. It is sectional drawing.

  More specifically, the unit cell UC1 has, as an example, a rectangular first as a ground layer made of a conductor laminated on a surface on the + Z side of a substrate 157 made of a dielectric (for example, a glass cloth base epoxy resin). A conductive layer 200 (hereinafter also referred to as a “rectangular conductive layer”), a first insulating layer 210 made of a dielectric layer stacked on the surface of the first conductive layer 200 on the + Z side, and the first insulating layer A substantially T-shaped conductive pattern 201 (hereinafter also referred to as a “T-shaped conductive pattern”) made of a conductor, stacked on the + Z side surface of the layer 210, and on the + Z side surface of the conductive pattern 201 A pair of rectangular insulating layers 211 provided separately at two locations in a region overlapping the T-shaped conductive pattern on the + Z side surface of the second insulating layer 211 made of a laminated dielectric, and the second insulating layer 211 And a conductive patch 202. Here, the horizontal side portion of the T-shape of the T-shaped conductive pattern is parallel to the X axis, and the vertical side portion is parallel to the Y axis. The conductive layer 200 and the first and second insulating layers 210 and 211 are integrated integrally (common) between the unit cells UC1. That is, the conductive patterns 201 of the plurality of unit cells UC1 are arranged between the first and second insulating layers 210 and 211.

  A square via 203 (through hole) is formed at a location corresponding to the tip of the long side of the T-shaped conductive pattern in the first insulating layer 210 (hereinafter also simply referred to as “tip”). Is formed. Therefore, hereinafter, the first insulating layer 210 is also referred to as “insulating layer with vias”.

  The tip portion of the T-shaped conductive pattern is thicker than the other portions and is inserted into the via 203 and is in contact with the flat rectangular conductive layer. Instead of this, the T-shaped conductive pattern is flattened, the portion corresponding to the via 203 of the rectangular conductive layer is made thicker than the other portions, inserted into the via 203, and brought into contact with the T-shaped conductive pattern. May be. Further, both the rectangular conductive layer and the T-shaped conductive pattern may be made flat, and a conductor for connecting the rectangular conductive layer and the T-shaped conductive pattern may be inserted into the via 203. Further, the inner edge of the via 203 may be plated with a metal or the like to form a plated hole. In short, it suffices if the rectangular conductive layer and the T-shaped conductive pattern can be conductively connected.

  The pair of conductive patches 202 individually correspond to both ends of the T-shaped lateral sides of the T-shaped conductive pattern on the + Z side surface of the second insulating layer 211 (hereinafter also referred to as “patch-side insulating layer”). Projected to the + Z side at the position.

The location management information 368 is information obtained by adding management information such as a reception time to the identification information and location information received from the wireless terminal 120. An example of a table storing the information is shown in FIG. FIG. 28 includes items of identification information, device name, owned department, latitude, longitude, floor number, building, and reception date and time. The identification information is information such as an IEEE extended address of the wireless terminal 120 that has transmitted the identification information. The latitude, longitude, number of floors, and building correspond to the positional information received together with the identification information. The reception date and time is the date and time when the management server 160 received the information. The device name is the name of the management target to which the wireless terminal 120 that transmitted the information is attached or the device name of the wireless terminal 120. The owned department is a department name that owns the wireless terminal 120 that has transmitted the information. Information on the device name and the owned department is associated with identification information by the management server 160 in advance.

  The input unit 370 accepts an input from the user so that the user searches for position information.

In the “location search system” shown in FIG. 30, based on the information stored in the storage unit 366, the owned department and device name related to the wireless terminal are displayed in a list on the screen. When the user selects a check box of a device to be searched through the input unit 370, a check mark is added. When all the devices to be searched are checked and the “Execute Search” button is selected, the search is executed and the screen is switched to a result display screen. In the example of FIG. 30, an example is shown in which the user performs a search for a device “UCS P3000” owned by “Sales Section 1”. FIG. 31 shows an example of the search result screen. When the “execute search” button is selected, the display unit 372 displays a floor plan of “A building 4th floor” where “UCS P3000” is located based on the data stored in the storage unit 366, the device name, Displays the reception date and time.

  The control unit 374 controls the operation of the management server.

  With the above configuration, the management server 160 in one embodiment can manage the location of the wireless terminal and search for the location. In particular, information representing the position of the wireless terminal itself can be directly received and managed, and the amount of calculation for searching for the position can be reduced.

  The management server 160 has the same functions as the conversion unit 346, the control unit 348, and the reception unit 342 included in the management device 140, and may have the same functions as the management device 140. This eliminates the need to provide the management device 140 separately.

  Below, the thought process in which the inventor of the present invention came up with the above embodiment and each modification will be described.

  In recent years, various location information management systems have been proposed in order to grasp and manage the position of a wireless terminal or a person or an article having a wireless terminal in a facility where accurate positioning using GPS or the like is difficult. In such a location information management system, a plurality of transmitters that transmit location information to a wireless terminal are installed, for example, on the ceiling of a room. However, a new power supply work is required to supply power to the transmitter, which is introduced. Cost can be high.

  Therefore, Patent Document 1 discloses a positioning system in which a wireless terminal receives unique information transmitted from a lighting device and transmits the unique information to a server to identify the position of the wireless terminal. In the positioning system according to Patent Literature 1, by providing the lighting device with a function of transmitting unique information to the wireless terminal, communication with the wireless terminal can be performed using the power supplied to the lighting device. There is no need to perform power supply construction at the time of introduction.

  However, in the positioning system according to Patent Document 1, when a communication device that transmits / receives unique information to / from a wireless terminal is incorporated in the lighting device, the communication device may interfere with light emitted from the light source of the lighting device depending on the arrangement. There is.

  Therefore, Patent Document 2 aims to enable position information management of a wireless terminal while suppressing a decrease in illumination function by arranging antennas of a communication device at both ends of a substrate provided with a light source. A developed lighting device is disclosed.

  However, in the illuminating device according to Patent Document 2, there is a limitation on the antenna design when arranging the light source and the antenna of the communication device on the substrate, and the antenna characteristics may be deteriorated due to the influence of the peripheral substrate. . That is, in the illumination device according to Patent Document 2, it is actually difficult to enable management of the location information of the wireless terminal while suppressing the deterioration of the illumination function.

  By the way, a small property (unit structure) such as a metal, a dielectric, a magnetic material, and a superconductor is arranged at a sufficiently short interval (about 1/10 or less of the wavelength) with respect to the wavelength. It is possible to artificially construct the medium that has it. This medium is called metamaterials in the sense that it belongs to a category that is larger than the category of natural media. The properties of the metamaterial vary depending on the shape and material of the unit structure and their arrangement.

  Among them, metamaterials whose equivalent permittivity ε and permeability μ are negative simultaneously are “left-handed materials (LHM)” because their electric field, magnetic field, and wave vector form a left-handed system. Named. This left-handed medium is referred to as a left-handed metamaterial in this specification. On the other hand, a normal medium in which the equivalent dielectric constant ε and permeability μ are simultaneously positive is called a “right-handed medium (RHM)”. In particular, left-handed metamaterials have the presence of waves (called backward waves) in which the signs of the wave group velocity (velocity of energy propagation) and phase velocity (velocity of phase advance) are reversed. It has unique properties such as amplification of evanescent waves that are exponentially attenuated waves in the propagation region. And the track | line which transmits the backward wave by a left-handed-type metamaterial can be artificially comprised. This is known as described in Reference 1 and Reference 2 below.

  Based on this left-handed medium configuration concept, a line for propagating backward waves by periodically arranging unit cells made of metal patterns has been proposed. Up to now, the transmission characteristics have been treated theoretically, this line has a left-handed transmission band, a band gap occurs between the left-handed transmission band and the right-handed transmission band, and the band gap width is unit cell. It is theoretically clear that it can be controlled by the reactance inside. These are described in Reference 3 below.
