In the following description, the "terminal identification information" indicates any terminal identification information among the plurality of terminal identification information. The terminal identification information includes a MAC address. When each communication terminal 5 receives 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 or attached to each of the electric devices (2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h) installed on the ceiling β of the indoor α. ing. Hereinafter, any electric device among the plurality of electric devices will be referred to as "electrical device 2".

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. As a result, 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 location information Xa to the gateway 7 by wireless communication. Then, the gateway 7 transmits the terminal identification information Aa and the location information Xa to the location management system 9 via the LAN 8e. In the position management system 9, by managing the terminal identification information Aa and the position information Xa, the administrator of the position management system 9 can grasp the position of the communication terminal 5a (management object 4a) in the indoor α.

Can be received to calculate the position on the earth. Then, the communication terminal (5g, 5h) uses a mobile communication system such as 3G (3rd Generation) or 4G (4th generation) to use 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 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 the above.

Shown.

FIG. 2 is a location information management system 1 according to an embodiment of the present invention. FIG. 2 shows lighting fixtures 100, 102, 104, 106 as electrical equipment 2 having a distribution device 3, wireless terminals 120, 122, 124 as communication terminals 5, management device 140, management server 160, lighting fixtures 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 that constitute the wireless network in FIG. 2 in an extracted manner.

The lighting fixtures 100, 102, 104, and 106 are attached to the ceiling of a room or the like, and continuously or intermittently wirelessly transmit position information such as background information, the number of floors of a building, and a building number related to the attached position. do. 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 by a wireless signal. The predetermined range is determined by the signal strength of the radio signal used. The luminaires are arranged so as to cover the areas to be managed in position, and the areas are configured so as not to overlap. Alternatively, even in the case of duplication, one of the lighting fixtures can be determined based on the intensity of the received radio wave on the side receiving the position information. In the example of FIG. 2, the conical dotted line shown below each luminaire represents a predetermined range. As a communication method for transmitting location information, for example, a ground complementary signal (Indoor Messaging System; IMES) can be used.

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

The wireless terminal 120 is within a range in which the wireless signal from the luminaire 100 can be received, and receives the position information of the luminaire 100. The reception of the position information of the luminaire 100 is performed using, for example, IMES. The wireless terminal 120 transmits information including its own identification information such as a network address to the lighting equipment 100 together with the received position information. The transmission is carried out over network 180 via short-range wireless communication, such as IEEE 802.15.4 and ZigBee®. In this case, the abbreviated address of IEEE802.15.4 or the 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 luminaire 100 are then transmitted to the management device 140 via the adjacent luminaire 102. The transmission / reception operation of 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 the 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 the building or for each room partitioned by a wall or the like. When the network 180 is a PAN (Personal Area Network) by IEEE 802.15.4 and ZigBee (registered trademark) and the network 190 is a LAN based on the IEEE 802.3 standard, the communication method is converted between them. When the identification information of the wireless terminal 120 is represented by a shortened 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 equipment. In the management server 160, the management object related to the wireless terminal is recorded in advance. Therefore, the location of the managed object can be searched by using this information.

The network 180 connects the respective luminaires 100, 102, 104, 106, the wireless terminals 120, 122, 124, and the management device 140, for example, a PAN configured by IEEE802.15.4 and ZigBee® standards. Is. When the PAN is composed of IEEE 802.15.4 and ZigBee® standard, the wireless terminal, lighting equipment, and management device each have the end device function, router function, and coordinator function defined by the ZigBee® standard. .. Then, each luminaire and wireless terminal come under the control of the management device at startup, constitute 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 may transmit the identification information and the position information to the management server using electric power sufficient to communicate with the nearest lighting equipment. can. In addition, since the lighting equipment is provided with a communication function with the wireless terminal and the management server, it is not necessary to lay a new infrastructure for supplying the power required for the communication function, and the introduction cost can be reduced. ..

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

Further, 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 equipment to which the position information is transmitted. As a result, the identification information and the location information can be transmitted to the management server by the shortest route.

Further, the functions of the management device may be integrated into 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. This makes it possible to manage the location information of the existing wireless terminal without attaching a tag.

Further, in addition to the above-mentioned position information, information for specifying a finer position such as information representing a section in a room may be included. This enables finer position management.

Moreover, the position management target may be a person. As a result, the whereabouts of a person can be managed by the system 1.

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

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