[Embodiment]
First, the illumination system 1 which concerns on embodiment of this invention is demonstrated based on drawing. FIG. 1 is a diagram illustrating an illumination system according to an embodiment. In the example illustrated in FIG. 1, the lighting system 1 includes a plurality of lighting devices 10A, 10B, 11A, 11B, a terminal 13, a server 15, and a monitoring device 17.

  Each of the lighting devices 10A, 10B, 11A, and 11B shown in FIG. 1 is a lighting device installed in a predetermined facility. For example, when a disaster occurs or the commercial power supply 6 that supplies power to the lighting device is lost, etc. (Hereinafter referred to as “emergency”) is an emergency lighting device such as an emergency light or a guide light that illuminates the inside of a facility using a predetermined emergency power source such as a storage battery. In addition, it is assumed that the lighting devices 10A, 10B, 11A, and 11B are installed at predetermined intervals in the facility.

  In the example shown in FIG. 1, the lighting device 10A includes a beacon 5A and an emergency lamp 2A that is a light source. Similarly, the illumination device 10B includes a beacon 5B and an emergency lamp 2C. On the other hand, the illumination device 11A includes a wireless communication module 7A and an emergency lamp 2B. The illumination device 11B includes a wireless communication module 7B and an emergency lamp 2D.

  In the following description, the emergency lamps 2 </ b> A to 2 </ b> D will be referred to as the emergency lamp 2 when they are not particularly distinguished. In the following description, beacon 5A and beacon 5B are described as beacon 5 when they are described without particular distinction. In the following description, the wireless communication module 7 </ b> A and the wireless communication module 7 </ b> B are described as the wireless communication module 7 when they are described without particular distinction. Moreover, in the following description, the illumination device 10 </ b> A and the illumination device 10 </ b> B are described as the illumination device 10 when they are described without particular distinction. In the following description, the illumination device 11 </ b> A and the illumination device 11 </ b> B are described as the illumination device 11 when they are described without particular distinction.

  The lighting devices 10 and 11 use the power supplied by the commercial power supply 6 in a state where a disaster occurs and the commercial power supply 6 is not lost, that is, in a non-emergency state (hereinafter referred to as “always”). It is an illuminating device that charges an emergency power source such as a storage battery and lights the emergency lamp 2 using the power stored in the emergency power source in an emergency.

  For example, in an emergency such as a power failure, the lighting devices 10 and 11 turn on the emergency lamp 2 to illuminate a room or a corridor for evacuation guidance. In another example, the lighting devices 10 and 11 are guide lights installed to indicate emergency exits and evacuation passages, and always turn on the emergency lamp 2 while charging the emergency power supply. By using the power stored in the emergency power supply, the emergency lamp 2 is turned on to indicate an emergency exit or an escape passage. The lighting devices 10 and 11 may be lighting devices other than emergency lights or guide lights. For example, the lighting devices 10 and 11 always use the commercial power source 6 to turn on the emergency lamp 2 and charge a predetermined storage battery, and in an emergency, use power supplied from the storage battery. Any lighting device that lights the emergency lamp 2 may be used.

  The beacon 5 transmits its own identification information at predetermined intervals using wireless communication. For example, the beacon 5 uses a one-way mode (sometimes referred to as “ADVERTISING MODE”) such as a wireless communication standard such as BLE (Bluetooth Low Energy) (registered trademark) that uses the 2.4 GHz band to identify information. Broadcast to the surroundings. Here, the identification information is information for identifying the beacon 5 or the lighting device 10 on which the beacon 5 is installed, and is, for example, a unique number assigned to the beacon 5 or the lighting device 10.

  The wireless communication module 7 transmits the identification information received via the terminal 13. Specifically, the wireless communication module 7 receives identification information from the terminal 13 or another wireless communication module 7 using a BLE bidirectional mode (sometimes referred to as “CONNECTION MODE”). In such a case, the wireless communication module 7 specifies a wireless communication module 7 that is different from the transmission source of the identification information, and transmits the received identification information to the specified wireless communication module 7. Further, when wireless communication with the wireless communication device 19 is possible, the wireless communication module 7 transmits the received identification information to the wireless communication device 19.

  The monitoring device 17 is a device that monitors the lighting devices 10 and 11 installed in the facility, and is an information processing device that manages the installation positions and inspection results of the lighting devices 10 and 11. Further, the monitoring device 17 has a function of notifying the presence and position of a user who has not evacuated from the facility by outputting the position of the terminal 13 located in the facility in an emergency by a process described later.

  The terminal 13 is a mobile device possessed by a user present in the facility, and is, for example, a mobile terminal such as a smartphone or a tablet terminal. The terminal 13 transmits and receives data to and from the server 15 using a mobile data communication standard such as 3G (Generation), 4G, or LTE (Long Term Evolution) or a wireless communication standard such as a wireless local area network (LAN). It has a function.

  The server 15 is an arbitrary server device arranged on the Internet, and provides a service for specifying the current position of the terminal 13 by processing to be described later.

  The wireless communication device 19 communicates with the beacon 5 included in the lighting device 10 by the wireless communication 12. For example, the wireless communication 12 is communication according to a 2.4 GHz band use Bluetooth Low Energy (hereinafter referred to as “BLE”) wireless communication standard. In FIG. 1, it is assumed that the wireless communication device 19 is in a position where wireless communication with the illumination device 11B is possible and can communicate with the monitoring device 17 via a wired or wireless communication path 20.

  Based on the above-described configuration, the lighting system 1 executes processing described below. First, the beacon 5A of the lighting device 10A and the beacon 5B of the lighting device 10B transmit identification information at predetermined time intervals. On the other hand, for example, when the terminal 13 receives the identification information transmitted by the beacon 5B via the wireless communication 12, the terminal 13 transmits the received identification information to the server 15 via the wireless communication 14.

  Here, the identification information received by the terminal 13 is predicted to be identification information transmitted by the beacon 5 of the lighting device 10 installed at a position where the terminal 13 and the wireless communication 12 can be performed. For this reason, for example, when the terminal 13 receives the identification information transmitted from the beacon 5B, the terminal 13 is predicted to be located in the vicinity of the lighting device 10B.

  Therefore, when receiving the identification information from the terminal 13, the server 15 specifies the current position of the terminal 13 using the received identification information. For example, the server 15 stores the installation position of the lighting device 10 and the identification information transmitted by the beacon 5 of the lighting device 10 in association with each other. In addition, when receiving the identification information from the terminal 13, the server 15 specifies an installation position associated with the received identification information. Then, the server 15 notifies the terminal 13 of the specified position via the wireless communication 14. As a result, the terminal 13 can notify the user of the current position by displaying the position notified from the server 15.

  Further, the server 15 transmits position information indicating the specified position to the monitoring device 17 via the communication path 16. In such a case, the monitoring device 17 displays the position indicated by the received position information. As a result, the monitoring device 17 can notify the manager of the facility or the lighting system 1 of whether or not there is a user in the facility or the current position of the user in the facility.

  On the other hand, if a failure occurs in the mobile communication network or the like due to a disaster such as an earthquake, the terminal 13 and the server 15 may not be able to communicate. In such a case, the terminal 13 cannot transmit the identification information received from the lighting device 10 to the server 15. Further, the terminal 13 cannot transmit the identification information to the monitoring device 17 via the wireless communication device 19 when the terminal 13 is not present at a position where wireless communication with the wireless communication device 19 is possible.

  As a result, the lighting system 1 cannot notify the current position to the user of the terminal 13 at the time of a disaster or the like, and there is a risk of hindering evacuation from the facility. Further, the lighting system 1 cannot display the position of the terminal 13 on the monitoring device 17 and may not be able to notify the administrator of users who have not evacuated from the facility.

  In order to solve these problems, the lighting system 1 performs the following processing. First, when receiving the identification information from the lighting device 10, the terminal 13 transmits the received identification information to the lighting device 11 located in the vicinity. For example, the terminal 13 is connected to the wireless communication module 7A included in the lighting device 11A, and transmits identification information to the wireless communication module 7A using the wireless communication 18 in the bidirectional mode.

  In such a case, the wireless communication module 7 </ b> A transmits the identification information received from the terminal 13 to the other wireless communication module 7. Specifically, the wireless communication module 7A connects to the wireless communication module 7B of the lighting device 11B installed in the vicinity, and transmits identification information to the wireless communication module 7B using the wireless communication 18 in the bidirectional mode. On the other hand, the wireless communication module 7B is installed at a position where wireless communication with the wireless communication device 19 is possible. Therefore, the wireless communication module 7B connects to the wireless communication device 19 and transmits identification information to the wireless communication module 7B using the wireless communication 18 in the bidirectional mode. That is, the wireless communication module 7 forms a mesh network that relays the identification information received from the terminal 13 to the wireless communication device 19.

  On the other hand, the wireless communication device 19 transmits the identification information received from the wireless communication module 7 </ b> B to the monitoring device 17 via the communication path 20. As described above, when receiving the identification information from the wireless communication device 19, the monitoring device 17 sets the position where the illumination device 10 corresponding to the received identification information is installed as the current position of the terminal 13, as with the server 15. Identify.

  When the current position of the terminal 13 is specified, the monitoring device 17 not only notifies the administrator of the specified position, but also returns the current position to the terminal 13 to return the current position to the user of the terminal 13. The location may be notified to facilitate evacuation from the facility. For example, when the current position of the terminal 13 is specified, the monitoring device 17 outputs position information indicating the specified position to the wireless communication device 19. In such a case, the wireless communication device 19 transmits the position information to the wireless communication module 7B via the wireless communication 18. On the other hand, the wireless communication module 7 </ b> B transmits the position information received from the wireless communication device 19 to the wireless communication module 7 </ b> A via the wireless communication 18. The wireless communication module 7 </ b> A transmits the received position information to the terminal 13 via the wireless communication 18. As a result, the terminal 13 can notify the user of the current position even when the terminal 13 cannot communicate with the server 15.

  In addition, the terminal 13 transmits the identification information which the beacon 5A of 10 A of lighting apparatuses transmits, when it is located in the vicinity of 10 A of lighting apparatuses. In such a case, since the monitoring device 12 and the server 15 receive the identification information transmitted by the beacon 5A of the lighting device 10A, it is determined that the position of the terminal 13 is in the vicinity of the lighting device 10A.

  Further, the wireless communication module 7 may not relay the identification information depending on the current position of the terminal 13. For example, the wireless communication module 7 </ b> A may directly transmit the identification information received from the terminal 13 to the wireless communication device 19 when the wireless communication module 7 </ b> A can directly perform wireless communication with the wireless communication device 19. Further, when the terminal 13 is located in the vicinity of the lighting device 11B, the terminal 13 transmits the identification information received from the beacon 5B to the wireless communication module 7B of the lighting device 11B. In such a case, the wireless communication module 7 </ b> B transmits the received identification information to the wireless communication device 19.

  In the example shown in FIG. 1, an illumination system having two illumination devices 10 (illumination devices 10A and 10B) having a beacon 5 and two illumination devices 11 (illumination devices 11A and 11B) having a wireless communication module 7 is used. 1 was described. However, the embodiment is not limited to this. For example, the lighting system 1 may have an arbitrary number of lighting devices 10 and lighting devices 11.

  As described above, the illumination system 1 includes the illumination device 10 in which the beacon 5 that transmits the identification information of the device itself is installed, and the illumination device in which the wireless communication module 7 that transmits the identification information received through the terminal 13 is installed. 11. As a result, the lighting system 1 can relay the identification information received by the terminal 13 from the beacon 5 to the wireless communication module 7 to any device such as the monitoring device 17.

  For this reason, the lighting system 1 can identify the position of the terminal 13 and notify the user of the terminal 13 and the administrator of the lighting system 1 even when the mobile communication network or the like cannot be used. Moreover, the illumination system 1 can construct | assemble the new network between the terminal 13 and the monitoring apparatus 17 easily only by installing the illuminating devices 10 and 11 in a plant | facility.

  Here, since the lighting devices 10 and 11 are emergency lighting devices, it is required by law or the like to be installed in the facility so as to satisfy a predetermined condition. For example, the lighting devices 10 and 11 are installed at predetermined intervals in the facility. Here, it is considered that the interval at which the lighting devices 10 and 11 are installed is sufficiently close to perform wireless communication 18 in the bidirectional mode with the adjacent lighting device 11. On the other hand, in order to relay the identification information transmitted from the terminal 13 to the monitoring device 17, a sufficient number of wireless communication modules 7 may be installed in accordance with the scale and structure of the facility.

  For this reason, the illumination system 1 has a plurality of illumination devices 11 installed at intervals that allow wireless communication 18 in the bidirectional mode with the adjacent illumination device 11, and the wireless communication device 19 is connected to any of the illumination devices 11. It may be installed at a position where it can communicate with. As a result, the lighting system 1 can relay the identification information output from the terminal 13 at an arbitrary position in the facility to the wireless communication device 19.

  Moreover, what is necessary is just to install the beacon 5 fully with respect to the magnitude | size of a facility, in order that the illumination system 1 may pinpoint the position of the terminal 13 more correctly. Therefore, the illumination system 1 has illumination devices 10 installed at predetermined intervals. As a result, the lighting system 1 can specify the position of the terminal 13 more accurately.

  In addition, when the lighting system 1 receives the identification information transmitted by the beacon 5, the terminal 13 that transmits the received identification information and the wireless communication module 7 that transmits the received identification information when receiving the identification information transmitted by the wireless communication module 7. When the communication device 19 and the identification information transmitted by the wireless communication device 19 are received, the monitoring device 17 having the current position of the terminal 13 in the vicinity of the lighting device 10 corresponding to the received identification information is provided. For this reason, the lighting system 1 can specify the position of the terminal 13 at the time of a disaster or the like, and notify the user of the terminal 13 or the administrator of the lighting system 1 of the specified position.

[Configuration Example of Lighting Device 10]
Next, the structure of the illuminating device 10 which concerns on embodiment is demonstrated using FIG. FIG. 2 is a diagram illustrating a configuration of the illumination device according to the embodiment. As shown in FIG. 2, the lighting device 10 includes an emergency lamp 2, an emergency power supply 3, an emergency lighting control unit 4, and a beacon 5, and is connected to a commercial power supply 6.

  The emergency lamp 2 is a light source that is lit at least during a so-called power failure when power supply from the commercial power supply 6 is stopped. As the emergency lamp 2, various light sources such as a fluorescent lamp and an LED (Light Emitting Diode) may be used depending on the purpose.

  The emergency power supply 3 is a storage battery (secondary battery) that supplies power to the emergency lamp 2 when power supply from the commercial power supply 6 is stopped. As the emergency power supply 3, various storage batteries may be used depending on the purpose. The emergency power supply 3 is charged via the emergency lighting control unit 4 when power is supplied from the commercial power supply 6. That is, the emergency power supply 3 is always charged by supplying power from the commercial power supply 6. Note that the emergency power source 3 may be charged by appropriately using various charging methods such as trickle charging and intermittent charging.

  The emergency lighting control unit 4 always charges the emergency power supply 3 and lights the emergency lamp 2 by the emergency power supply 3 in an emergency. For example, the emergency lamp 2 is lit by being supplied with power from the emergency lighting control unit 4 only in an emergency. Further, the emergency lighting control unit 4 has an internal memory for storing a program that defines various processing procedures and the necessary data, and various processes may be executed by these programs.

  The beacon 5 is a transmitter that transmits its own identification information at a predetermined interval by the wireless communication function in the one-way mode. Further, the beacon 5 operates by using a part of the power supplied from the commercial power source 6 to the emergency lighting control unit 4 at all times. The beacon 5 is supplied from the emergency power supply 3 to the emergency lighting control unit 4 in an emergency, and operates using a part of the electric power used for lighting the emergency lamp 2. For this reason, the illuminating device 10 having the beacon 5 can continue to transmit the identification information at a predetermined time interval at all times and in an emergency.

  The commercial power source 6 is, for example, a power source supplied from a predetermined power company. The commercial power supply 6 always charges the emergency power supply 3 and supplies power to the emergency lighting control unit 4. Further, the commercial power supply 6 may be any power supply means other than the power supply from the emergency power supply 3.

[Configuration Example of Lighting Device 11]
Next, the structure of the illuminating device 11 which concerns on embodiment is demonstrated using FIG. FIG. 3 is a diagram illustrating a configuration of the illumination device according to the embodiment. As shown in FIG. 3, the lighting device 11 includes an emergency lamp 2, an emergency power supply 3, an emergency lighting control unit 4, a wireless communication module 7, and a wireless communication module power supply 8. A power source 6 is connected. In the following description, the emergency lamp 2, the emergency power supply 3, and the emergency lighting control unit 4 included in the lighting device 11 are the emergency lamp 2, the emergency power supply 3, and the emergency lighting shown in FIG. 2. Description of the same function as that of the control unit 4 is omitted.

  The wireless communication module 7 uses the power supplied from the commercial power supply 6 at all times to transmit and receive data to and from the other wireless communication module 7, the terminal 13, and the wireless communication device 19 by the wireless communication function in the bidirectional mode. . For example, the wireless communication module 7 establishes a connection with a device to be communicated according to the BLE standard, and transmits / receives data such as identification information and position information. The wireless communication module 7 relays the identification information received from the beacon 5 by the terminal 13 to the wireless communication device 19.

  For example, upon receiving a connection request from the terminal 13, the wireless communication module 7 establishes a connection with the terminal 13 and receives identification information from the terminal 13. When the wireless communication module 7 receives a connection request from another wireless communication module 7, the wireless communication module 7 establishes a bidirectional communication connection with the other wireless communication module 7 and identifies it from the other wireless communication module 7. Receive information.

  Thus, when the identification information is received, the wireless communication module 7 searches for another wireless communication module 7 or a wireless communication device 19 installed in a communicable range. Here, when the wireless communication device 19 does not exist in the communicable range, the wireless communication module 7 establishes a connection by transmitting a connection request to another wireless communication module 7 present in the communicable range, and the terminal The identification information received from 13 is transmitted. On the other hand, when the wireless communication device 19 exists within a communicable range, the wireless communication module 7 transmits a connection request to the wireless communication device 19 to establish a connection, and transmits the identification information received from the terminal 13.

  Here, the bidirectional mode wireless communication function used by the wireless communication module 7 transmits more data in one communication (for example, one packet) than the one-way mode wireless communication function used by the beacon 5. can do. However, such a bidirectional mode wireless communication function consumes more power than a unidirectional mode wireless communication function. For this reason, when the power used by the wireless communication module 7 is supplied from the emergency power supply 3, the power for turning on the emergency lamp 2 may be tight in an emergency.

  Therefore, the lighting device 11 has a wireless communication module power supply 8 separately from the emergency power supply 3. For example, the wireless communication module power supply 8 is always realized by a storage battery that is charged via the emergency lighting control unit 4 with power supplied from the commercial power supply 6. The wireless communication module power supply 8 supplies power to the wireless communication module 7 when the power supply from the commercial power supply 6 is stopped in an emergency. As a result, the wireless communication module 7 can relay the identification information to the wireless communication device 19 without constraining the power for lighting the emergency lamp 2 not only at all times but also in an emergency. Note that the wireless communication module power supply 8 is realized by a storage battery (secondary battery) or the like, similar to the emergency power supply 3, and may be charged by appropriately using various charging methods such as trickle charging and intermittent charging. The power source 8 for the wireless communication module may be realized by a primary battery such as a commercially available dry battery or coin battery in addition to the storage battery.

[Configuration Example of Server 15]
Next, the configuration of the server 15 according to the embodiment will be described with reference to FIG. FIG. 4 is a diagram illustrating a configuration of the server according to the embodiment. As illustrated in FIG. 4, the server 15 includes a communication unit 150, a storage unit 151, and a control unit 153.

  The communication unit 150 is realized by a predetermined communication circuit such as a NIC (Network Interface Card), for example. For example, the communication unit 150 transmits and receives identification information and position information to and from the terminal 13 via the wireless communication 14 and the Internet N. The storage unit 151 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory, or a storage device such as a hard disk or an optical disk. For example, the storage unit 151 stores the illumination information database 152.

  For example, FIG. 5 is a diagram illustrating an example of information stored in the illumination information database according to the embodiment. As shown in FIG. 5, identification information and installation positions are registered in the illumination information database 152 in association with each other. Here, the installation position is identification information transmitted by the beacon 5 that outputs the associated identification information. For example, in the example illustrated in FIG. 5, in the illumination information database 152, the illumination device 10 that outputs the identification information “ID0001” is installed in the installation position “5th floor hall third row”, and the identification information “ID0002” is displayed. It shows that the illuminating device 10 to output is installed in the installation position "5th floor hall second row". The illumination information database 152 indicates that the illumination device 10 that outputs the identification information “ID0003” is installed at the installation position “5th floor hall first row”.

  Returning to FIG. 4, the description will be continued. The control unit 153 has an internal memory for storing a program that defines various processing procedures and the necessary data, and performs various processes using these programs. Particularly, as closely related to the present invention, The identification unit 154 and the transmission unit 155 are included.

  The specifying unit 154 specifies the current position of the terminal 13. For example, when the identification unit 154 receives the identification information received from the beacon 5 by the terminal 13 via the communication unit 150, the identification unit 154 identifies the installation position associated with the received identification information. The transmission unit 155 notifies the terminal 13 of the current position. For example, the transmission unit 155 generates position information indicating the installation position specified by the specifying unit 154, and transmits the generated position information to the terminal 13 that is the transmission source of the identification information. In addition, the transmission unit 155 transmits the generated position information to the monitoring device 17 via the communication path 16.

[Configuration Example of Monitoring Device 17]
Next, the configuration of the monitoring device 17 according to the embodiment will be described with reference to FIG. FIG. 6 is a diagram illustrating a configuration of the monitoring apparatus according to the embodiment. As illustrated in FIG. 6, the monitoring device 17 includes a communication unit 120, a storage unit 171, and a control unit 173.

  The communication unit 170 is realized by a predetermined communication circuit such as a NIC, for example. For example, the communication unit 170 receives position information from the server 15 via the communication path 16. Further, the communication unit 170 receives the identification information transmitted from the lighting device 11 to the wireless communication device 19 via the wireless communication 18 via the communication path 20. The storage unit 171 is realized by, for example, a semiconductor memory element such as a RAM or a flash memory, or a storage device such as a hard disk or an optical disk. For example, the storage unit 171 stores a lighting information database 172. In the illumination information database 172, the same information as the illumination information database 152 shown in FIG.

  Returning to FIG. 6, the description will be continued. The control unit 173 has an internal memory for storing a program that defines various processing procedures and necessary data, and performs various processes by using these programs.
