  FIG. 6 is a flowchart regarding the case where the transmitting / receiving terminal 500 such as an electronic tag moves. First, the transmission / reception terminal 500 such as an electronic tag transmits a positioning signal (beacon signal) (step S31).

  The first base station 300 that has received the positioning signal (beacon signal) of the transmission / reception terminal 500 transmits the positioning signal (beacon signal) to the server 600 via the second base station 400 (step S32).

  As shown in FIG. 1, a case will be described in which the first base station 300 that has received the positioning signal (beacon signal) transmitted by the transmission / reception terminal B502 is the first base station A301 and the second base station B302.

In the present embodiment, a lighting device 800 such as a street light or a security light is connected to the first base station 300.

  When the power supply 700 of the first base station 300 is secured and installed in the lighting device 800 such as a streetlight, the power supply 700 of the first base station 300 and the installation cost of the first base station 300 can be suppressed. it can.

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

  In addition, the first base station 300 connected to the lighting device 800 such as a street lamp can perform short-range wireless communication such as BLE by the BLE transceiver 310, but the interval between the adjacent first base stations 300 is communicated by LPWAN. Even in the case where the distance is possible, there may be a case where an area where short-range wireless communication such as BLE cannot be performed occurs.

  Therefore, for example, a short-range wireless communication transceiver such as a beacon signal receiver may be disposed between the adjacent first base stations 300. In this case, a transceiver of a short-range wireless communication device such as BLE may be connected to a lighting device 800 such as a streetlight.

  If it is such, 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 device 800, such as a streetlight.

  The control part 320 of the 1st base station 300 in this embodiment is connected with the illuminating device 800 by wire or radio | wireless.

  The controller 320 can control ON / OFF, dimming, and the like of the lighting device 800. The lighting device 800 preferably uses LEDs.

  In addition, when a failure such as 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. Further, the sensor node 200 and the transmission / reception terminal 500 may be able to communicate with each other.

(Electric signboard system using positioning and sensing network system 100)
In this embodiment, an electric signboard 900 is connected to the first base station 300.

  When the power supply 700 of the first base station 300 is secured or installed in the electric signboard 900, the power supply 700 of the first base station 300 or the installation cost of the first base station 300 can be suppressed.

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

  FIG. 10 is a conceptual diagram showing an electric signboard 900 on which a store name and the like at a store front are described. FIG. 11 is a conceptual diagram showing digital signage included in the electric signboard 900.

  As shown in FIG. 10, an electric signboard 900 is an electric signboard such as a convenience store, a store, a gas station, a car dealership, a bus stop, etc. facing the road where old people, children, etc. pass through the streets and residential areas. Is preferred.

  FIG. 11 shows a digital signage that is an example of an electric signboard 900. Since there is a possibility that digital signage will increase in the future in towns and residential areas, such a light signboard 900 may be used.

  The interval at which the first base station 300 is connected to the electric signboard 900 varies depending on the distance that 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 LPWAN, the first base station 300 may be installed at intervals of several kilometers.

  In addition, the first base station 300 connected to the electric signboard 900 can perform short-range wireless communication such as BLE by the BLE transmitting / receiving unit 310, but the distance between the adjacent first base stations 300 can be communicated by the LPWAN. Even in such a case, there may be a case where an area where short-range wireless communication such as BLE cannot be performed occurs.

  Therefore, for example, a short-range wireless communication transceiver such as a BLE such as a beacon signal receiver may be disposed between the adjacent first base stations 300. In this case, a transceiver of a short-range wireless communication device such as BLE may be connected to the electric signboard 900.

  If it is such, 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 electric signboard 900.

  The control unit 320 of the first base station 300 in this embodiment is connected to the electric signboard 900 by wire or wirelessly.

  And the control part 320 can control ON / OFF of the electric signboard 900, light control, the change of the image displayed, etc.

  In addition, when a failure such as lighting of the electric signboard 900 does not turn on or when a part needs to be replaced, 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. In the present embodiment, the sensor node 200 and the transmission / reception terminal 500 are not communicating with each other, but may be configured to be able to communicate with each other.

  Further, the sensor node 200 includes a sensor that consumes less power and can be operated with a battery or the like. Therefore, the sensor node 200 may not be installed on the lighting device 800 or the electric sign 900 but may be installed in a different place.

  Usually, in order to arrange the first base station 300, it is necessary to secure an installation location or to prepare an external power source, and thus there is a problem that it is expensive and the positioning system is difficult to spread.

  However, by installing the first base station 300 in the lighting device 800 for street lights or security lights, the electric signboard 900, etc., the cost can be suppressed and the installation of the positioning system can be easily spread.

  However, the installation of the first base station 300 on the streetlight or security light lighting device 800 or the lighting sign 900 is an administrator (owner) of the streetlight or security light lighting device 800 or the lighting sign 900 or the like. There are cases where there are few benefits. And there exists a possibility that a positioning system may become difficult to spread by this.

  However, since sensing is also performed, a merit for managers (owners) of the lighting device 800 for street lights and crime prevention lights, the electric signboard 900, and the like increases.

  For example, when the sensor node 200 is a passage sensor such as a person, a bicycle, a motorcycle, or a car, the administrator can know how much a person, bicycle, bike, car, or the like is passing, Can be useful.

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

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

  For this reason, it is not necessary for the business operator to perform temperature management or the like, and the number of measurements can be increased, thereby saving energy.

  In addition, the positioning system can be used, for example, to prevent children's lost children and elderly people from wandering and preventing crime.

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

  The present invention can be implemented in a mode in which various improvements, modifications, or variations are added without departing from the spirit of the present invention.
