In the present embodiment, since the first base station 300 and the sensor node 200 communicate using the LPWAN, the connection of the first base station 300 to the lighting device 800 may be several kilometers apart.

  In addition, although the first base station 300 connected to the lighting apparatus 800 such as a street lamp can perform short distance wireless communication such as BLE by the BLE transmission / reception unit 310, the distance between adjacent first base stations 300 communicates by LPWAN Even in the case of a possible distance, there may occur a region where short-distance wireless communication such as BLE can not be performed.

  Therefore, for example, a transceiver of near field communication such as a receiver of a beacon signal may be disposed between the adjacent first base stations 300. In this case, a transceiver of a near field communication device such as BLE may be connected to a lighting device 800 such as a street lamp.

  If it is such a thing, the power supply of the transmitter / receiver of short-distance non-plugging communication, such as BLE, can be made common with the power supply of the illuminating devices 800, such as a street lamp.

  The control unit 320 of the first base station 300 in the present embodiment is connected to the lighting device 800 in a wired or wireless manner.

  The control unit 320 can control ON / OFF of the lighting device 800, light control, and the like. Further, as the lighting device 800, one in which an LED is used is preferable.

  Further, in the case where a failure occurs such as the lighting does not light or when it is necessary to replace the lighting, the information is transmitted to the server 600 via the LPWA relay unit 330.

  In this case, the second base station 400 may not be interposed. Also, the sensor node 200 and the transmitting and receiving terminal 500 may be able to communicate.

(Lighting signboard system using positioning and sensing network system 100)
In the present embodiment, a lighting sign 900 is connected to the first base station 300.

  When securing the power source 700 of the first base station 300 or installing place is the one of the illuminated sign 900, securing of the power source 700 of the first base station 300 and cost for installing the first base station 300 can be suppressed.

  As shown in FIG. 9, FIG. 10 and FIG. 11, some of the plurality of illuminated signs 900 can be connected to the first base station 300, and the illuminated signs 900 in the periphery can be used as the sensor node 200. .

  FIG. 10 is a conceptual diagram showing a illuminated signboard 900 in which a store name and the like at a storefront of the store are described. FIG. 11 is a conceptual diagram showing digital signage included in the lighting sign 900.

  As shown in FIG. 10, the illuminated signboard 900 is a illuminated signboard such as a convenience store, a store, a gas station, a car shop, a bus stop, etc. facing the road through which old people and children pass in town or residential area. Is preferred.

  FIG. 11 is a digital signage which is an example of the illuminated sign 900. Such a thing may be used as the lighting signboard 900 because digital signage may increase in the future in towns and residential areas.

  The interval at which the first base station 300 is connected to the lighting sign 900 varies depending on the distance in which the first base station 300 can communicate with the sensor node 200. In the present embodiment, since the first base station 300 and the sensor node 200 communicate using the LPWAN, the installation of the first base station 300 may be several kilometers apart.

  In addition, although the first base station 300 connected to the illuminated sign 900 is capable of short distance wireless communication such as BLE by the BLE transmission / reception unit 310, the distance between adjacent first base stations 300 can be communicated by LPWAN. Even in this case, an area where short distance wireless communication such as BLE can not be generated may occur.

  Therefore, for example, a transceiver of near field communication such as BLE, such as a receiver of a beacon signal, may be disposed between adjacent first base stations 300. In this case, a transceiver of a near field communication device such as BLE may be connected to the illuminated sign 900.

  If it is such a thing, the power supply of the transmitter-receiver of short-distance non-plugging | communication, such as BLE, can be made common with the power supply of the lighting signboard 900. FIG.

  The control unit 320 of the first base station 300 in the present embodiment is connected to the illuminated sign 900 by wire or wirelessly.

  Then, the control unit 320 can control ON / OFF of the illuminated sign 900, light control, change of the displayed image, and the like.

  In the case where a failure occurs such as the lighting of the illuminated sign 900 does not light, or when it is necessary to replace a part, the information is transmitted to the server 600 via the LPWA relay unit 330.

  In this case, the second base station 400 may not be interposed. Moreover, although the sensor node 200 and the transmission / reception terminal 500 do not communicate in this embodiment, they may communicate.

  Further, since the sensor node 200 has a small power consumption and has a sensor that can be operated by a battery or the like, the sensor node 200 may be installed in a different place from the lighting device 800 or the lighting sign 900 without being installed.

  Usually, in order to arrange the first base station 300, it is necessary to secure an installation place and to prepare an external power supply, which causes a problem that it is costly and it is difficult to expand the positioning system.

  However, the cost can be reduced by installing the first base station 300 on the lighting device 800 for the streetlight or the crime prevention light, the lighting signboard 900, and the like, and the installation of the positioning system can be easily spread.

  However, installing the first base station 300 on the lighting device 800 for the streetlight or crime prevention light, the lighting signboard 900, etc. requires the administrator (holder) of the lighting device 800 for the street light or crime prevention light or the lighting signboard 900 etc. There may be little benefit for you. And there exists a possibility that the positioning system may become difficult to spread by this.

  However, by performing sensing as well, the merits become greater for managers (holders) such as the lighting devices 800 for street lights and crime prevention lights and the lighting signboard 900.

  For example, if the sensor node 200 is a passing sensor such as a person, a bicycle, a motorbike, or a car, the manager can grasp how much a person, a bicycle, a motorbike, a car, or the like has passed. It can be useful for

  Moreover, if it is such a thing, judgment of the necessity of replacement | exchange of a street lamp or a crime prevention light, failure, etc. will become easy.

  In addition, for example, in stores such as convenience stores and supermarkets, temperature management of the inside of a store, a refrigerator, a freezer, etc. is necessary, but temperature management of a refrigerator or a freezer is automated by installing a sensor node for measuring the temperature. .

  For this reason, it is not necessary for the employer to manage the temperature and the like by the employees, and the number of times of measurement can be increased, and energy saving can be achieved.

  In addition, the positioning system can also be used to prevent, for example, a child's lost child and an old man's bribe, and a crime.

  For this reason, installation of a positioning system and a sensing system becomes easy to spread.

  The present invention can also be carried out in variously modified, modified or modified modes without departing from the scope of the invention.
