1. System 2. 2. Hardware configuration example Function 4. Operation sequence (1. System)
FIG. 1 shows a location information management system 1 according to an embodiment of the present invention. FIG. 1 includes lighting fixtures 100, 102, 104, 106, wireless terminals 120, 122, 124, a management device 140, a management server 160, a network 180 and a network 190 that include lighting fixtures, wireless terminals, and management devices. . Here, the network 180 is a wireless network managed by the management device 140. FIG. 2 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. 1, 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. 1, 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.

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

  The management device 140 connects the network 180 and the network 190 to each other, and bridges 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. 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 system is converted between them. If the identification information of the wireless terminal 120 is represented by an IEEE 802.15.4 abbreviated address, 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 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, management objects related to wireless terminals are recorded in advance. Therefore, the location of the management target can be searched 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, for example, a PAN configured according to IEEE802.15.4 and ZigBee (registered trademark) standards. It is. When PAN is configured with IEEE802.15.4 and ZigBee (registered trademark) standards, wireless terminals, lighting fixtures, and management devices have end device functions, router functions, and coordinator functions defined by the ZigBee (registered trademark) standards, respectively. . Each lighting device and wireless terminal enters the management of the management device at the time of activation, forms a PAN, and determines the minimum path to the management device.

  The network 190 is a network that connects the management apparatus 140 and the management server 160, and is, for example, a LAN defined by the IEEE 802.3 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 using power that can be communicated with the nearest lighting fixture. it can. 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 LE, ANT, Z-Wave, and 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.
