Further, in the following description, “position information” indicates any position information among a plurality of position information, and “device identification information” indicates any device identification information among a plurality of device identification information. A MAC (Media Access Control) address can be used as the device identification information.

  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. I remember. In the following description, “terminal identification information” refers to arbitrary terminal identification information among a plurality of terminal identification information. The terminal identification information may be a MAC address. Upon receiving the position information from the distribution device 3, each communication terminal 5 transmits the position information to the distribution device 3 together with its own terminal identification information.

  Further, each distribution device 3 is built in the electric equipment (2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h) installed on the ceiling β of the indoor α, or attached to the outside thereof. ing. Note that, hereinafter, an arbitrary electric device among the plurality of electric devices is referred to as “electric device 2”.

  Each electric device 2 supplies electric power to each distribution device 3. Of these, the electric device 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 of a wireless LAN (Local Area Network). The electric device 2d is a speaker.

  Next, an outline of an example of a position information management method using the position information management system 1 will be described. In the present embodiment, for example, the distribution device 3a installed on the ceiling β of the indoor α distributes the 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 the terminal identification information Aa and the 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.

  As a result, the distribution device 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 system 9 via the LAN 8e. By managing the terminal identification information Aa and the position information Xa in the position management system 9, the manager of the position management system 9 can grasp the position of the communication terminal 5a (managed object 4a) in the indoor α.

  Further, among the communication terminals 5, particularly the communication terminals (5g, 5h) are wireless signals (time information, orbit information, etc.) from the GPS (Global Positioning System) satellite 999 in the outdoor γ, as shown in FIG. Can be received and the position on the earth can be calculated. Then, the communication terminals (5g, 5h) utilize a mobile communication system such as 3G (3rd Generation), 4G (4th generation) or the like, and the base station 8a, the mobile communication network 8b, the gateway 8c, the Internet 8d, and the LAN 8e. It is also possible to transmit the terminal identification information (Ag, Ah) and the position information (Xg, Xh) for identifying the communication terminals (5g, 5h) to the position management system 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. Moreover, at least three GPS satellites are required to measure the latitude and longitude on the earth (four are required if the altitude is included), but for the sake of simplicity, in FIG. Shows.

  FIG. 2 shows a position information management system 1 according to an embodiment of the present invention. FIG. 2 shows lighting devices 100, 102, 104, 106 as electric devices 2 having a distribution device 3, wireless terminals 120, 122, 124 as communication terminals 5, a management device 140, a management server 160, lighting devices and wireless terminals. It has a network 180 and a network 190 composed of a management device and a management device. Here, the network 180 is a wireless network managed by the management device 140. FIG. 3 shows the lighting fixtures 100, 102, 104, 106, the wireless terminals 120, 122, 124, and the management device 140 extracted from FIG.

  The lighting fixtures 100, 102, 104, and 106 are attached to, for example, the ceiling of a room, and wirelessly transmit position information such as history information, floor number of the building, and building number related to the installed position continuously or intermittently. To do. The lighting fixtures 100, 102, 104, 106 transmit the positional information held by each of them to a predetermined range by a wireless signal. The predetermined range is defined by the signal strength of the wireless signal used. The luminaire is arranged so as to cover a region whose position is to be managed, and is configured so that the respective regions do not overlap. Alternatively, even if they overlap, any one of the lighting devices can be determined on the side receiving the position information based on the intensity of the 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 the position information, for example, a ground complementary signal (Indoor Messaging System; IMES) can be used.

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

  The wireless terminal 120 is in a range where the wireless signal from the lighting fixture 100 can be received, and receives the position information of the lighting fixture 100. The reception of the position information of the lighting fixture 100 is performed using IMES, for example. The wireless terminal 120 transmits, to the lighting fixture 100, information including its own identification information such as a network address together with the received position information. The transmission is performed through the network 180 by short-range wireless communication such as IEEE802.15.4 and ZigBee (registered trademark). In this case, a shortened address of IEEE802.15.4 or an IEEE extended (MAC) address can be used as the identification information of the wireless terminal 120. The identification information and the position information transmitted to the lighting fixture 100 are then transmitted to the management device 140 via the adjacent lighting fixture 102. The transmission / reception operation in the wireless terminal 120 is performed at a predetermined timing in the wireless terminal 120 or at a timing when a change in acceleration is detected by an acceleration sensor included in the wireless terminal 120.

  The management device 140 connects the network 180 and the network 190 to each other, and bridges the data transmitted from the network 180 side to the network 190. The management device 140 is installed, for example, for each floor of a building or for each room partitioned by walls or the like. When the network 180 is a PAN (Personal Area Network) based on IEEE802.15.4 and ZigBee (registered trademark) and the network 190 is a LAN based on the IEEE802.3 standard, the communication method between them is converted. Further, when the identification information of the wireless terminal 120 is represented by an abbreviated address of IEEE802.15.4, it is converted into an IEEE extended address based on the information at the time of PAN configuration and transmitted to the management server 160.

  The management server 160 records the identification information and the position information received via the management device 140 together with the reception date and time, and manages the position of the lighting fixture. In the management server 160, the management target object related to the wireless terminal is recorded in advance. Therefore, it is possible to search the whereabouts of the management target object using these pieces of information.

  The network 180 connects the respective lighting fixtures 100, 102, 104, 106, the wireless terminals 120, 122, 124, and the management device 140, and is configured by, for example, IEEE802.15.4 and ZigBee (registered trademark) PAN. Is. When the PAN is configured with the IEEE802.15.4 and ZigBee (registered trademark) standards, the wireless terminal, the lighting device, and the management device each have an end device function, a router function, and a coordinator function defined by the ZigBee (registered trademark) standard. .. Then, the respective lighting fixtures and wireless terminals are placed under the control of the management device at the time of startup, form a PAN, and the minimum route to the management device is determined.

  The network 190 is a network that connects the management device 140 and the management server 160, and is, for example, a LAN defined by the IEEE802.3 standard.

  As described above, in the position information management system 1 according to the embodiment of the present invention, the wireless terminal can transmit the identification information and the position information to the management server by using the electric power that can communicate with the nearest lighting fixture. it can. Further, since the lighting device 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 the power required for the communication function, and the introduction cost can be reduced. ..

  The position information of the lighting equipment may be provided through the network 180. This eliminates the need for transmitting means such as IMES for transmitting position information.

  In addition, the wireless terminal may transmit the identification information and the position information to the management device 140 when the management device is located closer to the lighting fixture that has transmitted the position information. Thereby, the identification information and the position information can be transmitted to the management server by the shortest route.

  Further, the functions of the management device may be integrated with the management server. This eliminates the need for a separate management device.

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

  Further, in addition to the position information described above, information that specifies a finer position, such as information indicating a section in a room, may be included. This enables finer position management.

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

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

The network 190 may also include multiple types of networks such as the Internet. As a result, it becomes possible to manage the position information of the wireless terminal regardless of the physical position between the network 180 and the management server 160.
