　各々の照明装置１０は、住宅等の施設及び施設周囲の空間全体を照明することができるように、施設の屋外に設置される。各々の照明装置１０は、例えば、スポットライト１０ａ、表札灯１０ｂ、ダウンライト１０ｃ、ポーチライト１０ｄ、ガーデンライト１０ｅ等である。スポットライト１０ａ、表札灯１０ｂ、ダウンライト１０ｃ、ポーチライト１０ｄ、ガーデンライト１０ｅ等は、ＢＬＥ（Ｂｌｕｅｔｏｏｔｈ（登録商標）　Ｌｏｗ　Ｅｎｅｒｇｙ）のアドホックネットワークを構成し、それぞれが相互に通信可能である。 Each lighting device 10 is installed outside the facility so that it can illuminate the facility such as a house and the entire space around the facility. Each of the lighting devices 10 is, for example, a spotlight 10a, a nameplate light 10b, a downlight 10c, a porch light 10d, a garden light 10e, or the like.

　各々の照明装置１０には、情報出力部２０がそれぞれ搭載される。情報出力部２０は、各々の照明装置１０に一体的に備えられていてもよく、別体として各々の照明装置１０に接続されていてもよい。この場合、情報出力部２０は、各々の照明装置１０と電気的かつ通信可能に接続される。 An information output unit 20 is mounted on each lighting device 10. The information output unit 20 may be integrally provided in each lighting device 10, or may be separately connected to each lighting device 10. In this case, the information output unit 20 is electrically and communicatively connected to each lighting device 10.
　情報出力部２０は、情報出力部２０の周囲に存在する移動体情報を車両５０に送信する。この移動体９０は、施設の傍を通行又は停止する車両５０及び人等、施設から出発する車両５０及び人等である。 The information output unit 20 transmits the mobile body information existing around the information output unit 20 to the vehicle 50. The moving body 90 is, for example, a vehicle 50 or a person passing by or stopping by the facility, or a vehicle 50 or a person departing from the facility.
　情報出力部２０は、検知部２１と、通信部２２とを備える。 The information output unit 20 includes a detection unit 21 and a communication unit 22.
　検知部２１は、検知部２１の周囲、つまり照明装置１０の周囲に存在する移動体９０を検知するセンサである。具体的には、検知部２１は、移動体９０の位置、移動体９０の速度、移動体９０の進行方向、及び、移動体９０の種類等を検知して取得する。検知部２１は、例えば、ＴＯＦ（Ｔｉｍｅ　ｏｆ　Ｆｌｉｇｈｔ）カメラ、赤外線カメラ若しくは可視光カメラ等の撮像装置、レーザーレーダ又は人感センサ等であり、これらのセンサを組み合わせて用いてもよい。 The detection unit 21 is a sensor that detects a moving body 90 that exists around the detection unit 21, that is, around the illumination device 10. Specifically, the detection unit 21 detects and acquires the position of the moving body 90, the speed of the moving body 90, the traveling direction of the moving body 90, the type of the moving body 90, and the like. The detection unit 21 is, for example, an imaging device such as a TOF (Time of Flight) camera, an infrared camera or a visible light camera, a laser radar or a human sensor, and these sensors may be used in combination.
　検知部２１は、検知した移動体情報を通信部２２に出力する。つまり検知部２１は、検知部２１の周囲に存在する移動体９０から車両５０を抽出し、抽出した車両５０に対し、通信部２２を介して移動体情報を送信する。なお、車両５０が情報出力部２０に対して移動体情報の要求を行うことで、検知部２１が通信部２２を介して移動体情報を車両５０に送信してもよい。 The detection unit 21 outputs the detected mobile body information to the communication unit 22. That is, the detection unit 21 extracts the vehicle 50 from the moving body 90 existing around the detection unit 21, and transmits the moving body information to the extracted vehicle 50 via the communication unit 22. The detection unit 21 may transmit the mobile body information to the vehicle 50 via the communication unit 22 by the vehicle 50 requesting the mobile body information from the information output unit 20.
　ここで移動体情報は、移動体９０の位置情報、移動体９０の速度情報、移動体９０の進行方向情報、及び、移動体９０の種類情報等を含む。具体的には、移動体９０の位置情報は、検知部２１が検知した時点の移動体９０の位置を示す情報であり、検知部２１から移動体９０まで、又は、車両５０から当該車両５０を除く移動体９０までの相対的な位置情報であってもよく、緯度及び経度等といった絶対的な位置情報であってもよい。また、移動体９０の速度情報は、検知部２１が検知した時点の移動体９０の走行速度を示す情報である。さらに、移動体９０の進行方向情報は、検知部２１が検知した時点の移動体９０の進行方向を示す情報であり、例えば、移動体９０が進行する方位を示す情報である。また、移動体９０の種類情報は、子供、老人、大人、自転車、自動二輪車又は自動車等といった移動体９０の種類を特定する情報である。 Here, the moving body information includes position information of the moving body 90, speed information of the moving body 90, traveling direction information of the moving body 90, type information of the moving body 90, and the like. Specifically, the position information of the moving body 90 is information indicating the position of the moving body 90 at the time when the detecting unit 21 detects the moving body 90, and detects the moving body 90 from the detecting unit 21 to the moving body 90. It may be relative position information up to the moving body 90 to be excluded, or absolute position information such as latitude and longitude. The speed information of the moving body 90 is information indicating the traveling speed of the moving body 90 at the time when the detection unit 21 detects the moving speed. Furthermore, the traveling direction information of the moving body 90 is information indicating the traveling direction of the moving body 90 at the time of detection by the detection unit 21, and is, for example, information indicating the azimuth in which the moving body 90 is traveling. The type information of the moving body 90 is information that specifies the type of the moving body 90, such as a child, an elderly person, an adult, a bicycle, a motorcycle, or an automobile.
　なお、移動体情報には、車両５０に関する情報が含まれていてもよいが、当然のことながら、車両５０以外の他の移動体情報が含まれる。 Note that the mobile body information may include information on the vehicle 50, but naturally, other mobile body information other than the vehicle 50 is also included.
　通信部２２は、検知部２１が取得した移動体情報を車両５０に送信する無線通信モジュールである。具体的には、通信部２２は、情報出力部２０つまり照明装置１０の周囲に存在する車両５０が使用するための移動体情報を、車両５０に送信する。通信部２２は、移動体情報をブロードキャストで、周囲に存在する車両５０に送信する。例えば、通信部２２は、車両５０との間で、Ｗｉ－Ｆｉ等の通信プロトコルを用いた無線通信が行われる。 The communication unit 22 is a wireless communication module that transmits the mobile body information acquired by the detection unit 21 to the vehicle 50. Specifically, the communication unit 22 transmits, to the vehicle 50, the information output unit 20, that is, the mobile body information to be used by the vehicle 50 existing around the lighting device 10. The communication unit 22 broadcasts mobile unit information to the vehicles 50 existing in the vicinity. For example, the communication unit 22 performs wireless communication with the vehicle 50 using a communication protocol such as Wi-Fi.
　また、各々の照明装置１０は、制御部１１と、発光モジュール１２と、電源部１３とを備える。 Each lighting device 10 also includes a control unit 11, a light emitting module 12, and a power supply unit 13.
　制御部１１は、発光モジュール１２の点灯及び消灯を制御するコントローラである。また、制御部１１は、発光モジュール１２の点灯状態を制御するコントローラでもある。つまり、制御部１１は、発光モジュール１２の点灯状態を制御する調光回路及び調色回路を有する。制御部１１は、指示された調光率に応じて発光モジュール１２の発する光の光量を多くしたり、少なくしたりする。また、制御部１１は、指示された色温度に応じて、発光モジュール１２が発する光の色温度を高くしたり低くしたりする。このように、制御部１１は、発光モジュール１２を制御することで、調光率を変化させた光を出射したり、調色率を変化させた光を出射したりする。 The control unit 11 is a controller that controls turning on and off of the light emitting module 12. The control unit 11 is also a controller that controls the lighting state of the light emitting module 12. That is, the control unit 11 has a light control circuit and a color control circuit that control the lighting state of the light emitting module 12. The control unit 11 increases or decreases the amount of light emitted from the light emitting module 12 according to the instructed dimming rate. Further, the control unit 11 raises or lowers the color temperature of the light emitted by the light emitting module 12 according to the instructed color temperature. In this way, the control unit 11 controls the light emitting module 12 to emit light with a dimming rate changed or emit light with a toned rate changed.
　なお、照明装置１０は、照度センサを有していてもよい。具体的には、周囲が明るいことを照度センサが検知すれば、制御部１１は、発光モジュール１２の発する光の光量が少ないコマンドを電源部１３に送信する。また、周囲が暗いことを照度センサが検知すれば、制御部１１は、発光モジュール１２の発する光の光量が多い制御コマンドを電源部１３に送信したりする。これにより、照明装置１０は、周囲の照度に応じて、明るく点灯したり暗く点灯したりする。 Note that the lighting device 10 may have an illuminance sensor. Specifically, if the illuminance sensor detects that the surroundings are bright, the control unit 11 transmits a command with a small amount of light emitted from the light emitting module 12 to the power supply unit 13. Further, when the illuminance sensor detects that the surroundings are dark, the control unit 11 sends a control command with a large amount of light emitted from the light emitting module 12 to the power supply unit 13. As a result, the lighting device 10 lights up brightly or darkly depending on the ambient illuminance.
　なお、照明装置１０は、人感センサを有していてもよい。制御部１１は、人感センサから取得した検知情報に基づいて、発光モジュール１２の点灯及び消灯を制御してもよい。人感センサは、照明装置１０の周囲における人の存在の有無を検知するセンサであり、人の存在を検知すると、検知した情報を制御部１１に送信してもよい。例えば、制御部１１は、人感センサから検知情報を取得すると、発光モジュール１２を点灯させるコマンドを電源部１３に送信したり、人感センサから検知情報を取得すると、点灯している発光モジュール１２を消灯させるコマンドを電源部１３に送信したりしてもよい。これにより、照明装置１０は、人が存在すれば点灯し、人が存在しなくなれば消灯する。 Note that the lighting device 10 may include a motion sensor. The control unit 11 may control the turning on and off of the light emitting module 12 based on the detection information acquired from the motion sensor. The human sensor is a sensor that detects the presence or absence of a person in the vicinity of the lighting device 10. When the presence of a person is detected, the detected sensor may transmit the detected information to the control unit 11. For example, when the control unit 11 acquires the detection information from the motion sensor, it sends a command to turn on the light emitting module 12 to the power supply unit 13, and when the detection information is acquired from the motion sensor, the control unit 11 lights the light emitting module 12. A command to turn off may be transmitted to the power supply unit 13. As a result, the lighting device 10 is turned on when the person is present, and is turned off when the person is not present.
　発光モジュール１２は、照明装置１０が周囲を照明するための光を出射する。発光モジュール１２は、光を放射状に発するＬＥＤ（Ｌｉｇｈｔ　Ｅｍｉｔｔｉｎｇ　Ｄｉｏｄｅ）を有するモジュールである。発光モジュール１２は、例えば白色光を出射するように構成される光源と、光源を実装するための実装基板とを有する。 The light emitting module 12 emits light for the illumination device 10 to illuminate the surroundings. The light emitting module 12 is a module having LEDs (Light Emitting Diodes) that radially emit light. The light emitting module 12 has, for example, a light source configured to emit white light, and a mounting substrate for mounting the light source.
　光源は、ＣＯＢ（Ｃｈｉｐ　Ｏｎ　Ｂｏａｒｄ）型ＬＥＤで構成され、実装基板上に実装されたベアチップ（ＬＥＤチップ）である複数の青色ＬＥＤと、それら青色ＬＥＤを封止し、黄色蛍光体を含む封止部材とを有する。実装基板には、光源を発光させるために、直流電流を電源部１３から受電する電極端子が形成される。電極端子には、配線に接続されたリード線等を介して直流電流が供給される。なお、光源は、ＣＯＢ型ＬＥＤに限定されず、ＳＭＤ（Ｓｕｒｆａｃｅ　Ｍｏｕｎｔ　Ｄｅｖｉｃｅ）型のＬＥＤであってもよい。 The light source is composed of COB (Chip On Board) type LEDs, and a plurality of blue LEDs, which are bare chips (LED chips) mounted on a mounting board, and these blue LEDs are sealed, and a sealing including a yellow phosphor is included. And a member. Electrode terminals for receiving a direct current from the power supply unit 13 are formed on the mounting substrate in order to make the light source emit light. DC current is supplied to the electrode terminals via lead wires connected to the wiring. The light source is not limited to the COB type LED, but may be an SMD (Surface Mount Device) type LED.
　電源部１３は、発光モジュール１２に電力を供給する電源回路が内蔵されたモジュールである。電源部１３に内蔵された電源回路は、電源部１３に接続された配線から供給された交流電流を直流電流に変換し、変換した直流電流を、リード線を介して発光モジュール１２の光源に供給する。 The power supply unit 13 is a module having a built-in power supply circuit that supplies electric power to the light emitting module 12. The power supply circuit built in the power supply unit 13 converts the alternating current supplied from the wiring connected to the power supply unit 13 into a direct current, and supplies the converted direct current to the light source of the light emitting module 12 through the lead wire. To do.
　車両５０は、各々の照明装置１０に搭載される情報出力部２０から、周囲に存在する移動体情報を受信する。車両５０は、この移動体情報に基づいて、走行を継続したり、走行を停止したりするといった判断に用いることができる。 The vehicle 50 receives information about moving bodies existing in the surroundings from the information output unit 20 mounted on each lighting device 10. The vehicle 50 can be used to determine whether to continue traveling or stop traveling based on this mobile body information.
　［動作］
　次に、情報システム１ａ及び情報送信方法の動作について説明する。 [motion]
Next, operations of the information system 1a and the information transmission method will be described.
　図３は、実施の形態１に係る情報システム１ａの動作を例示するシーケンス図である。 FIG. 3 is a sequence diagram illustrating the operation of the information system 1a according to the first embodiment.
　図３に示すように、各々の照明装置１０に搭載される情報出力部２０の検知部２１は、照明装置１０の周囲に存在する移動体９０を検知する（Ｓ１１）。つまり、照明装置１０の周囲には車両５０が存在している。 As shown in FIG. 3, the detection unit 21 of the information output unit 20 mounted on each lighting device 10 detects the moving body 90 existing around the lighting device 10 (S11). That is, the vehicle 50 exists around the lighting device 10.
　次に、情報出力部２０は、当該車両５０に対して移動体情報を送信する（Ｓ１２）。車両５０は、移動体情報を受信する。そして、情報システム１ａは、処理を終了する。 Next, the information output unit 20 transmits mobile body information to the vehicle 50 (S12). The vehicle 50 receives the mobile body information. Then, the information system 1a ends the process.
　このように、例えば施設から車両５０が出発する場合に、照明装置１０の周囲に存在する移動体９０（出発しようとする車両５０、及び、当該車両５０以外の移動体９０）を検知し、検知した移動体情報を当該車両５０に送信する。これにより、車両５０は、移動体情報（車両５０以外の他の移動体情報）を受信することができる。このため、車両５０は、移動体情報に示される移動体９０の位置情報、移動体９０の速度情報、移動体９０の進行方向情報、及び、移動体９０の種類情報に基づいて、車両５０を出発させることができるかどうかの判断に用いることができる。 Thus, for example, when the vehicle 50 departs from the facility, the moving body 90 existing around the lighting device 10 (the vehicle 50 that is about to depart and the moving body 90 other than the vehicle 50) is detected and detected. The moved mobile body information is transmitted to the vehicle 50. Thereby, the vehicle 50 can receive the mobile body information (mobile body information other than the vehicle 50). Therefore, the vehicle 50 controls the vehicle 50 based on the position information of the moving body 90, the speed information of the moving body 90, the traveling direction information of the moving body 90, and the type information of the moving body 90 indicated by the moving body information. It can be used to judge whether it is possible to start.
　［作用効果］

　上述したように、本実施の形態に係る情報システム１ａは、施設の屋外に設置される情報システム１ａである。また、情報システム１ａは、周囲に存在する移動体情報を取得する情報出力部２０を備える。そして、情報出力部２０は、移動体情報を車両５０に送信する。 As described above, the information system 1a according to the present embodiment is the information system 1a installed outside the facility. In addition, the information system 1a includes an information output unit 20 that acquires mobile body information existing in the surrounding area. Then, the information output unit 20 transmits the mobile body information to the vehicle 50.
　通常、住宅街等では、障害物による死角が多く、移動体を検知するインフラセンサ（例えばオービス（登録商標）等のセンサ）が設置されていない環境下にある。しかし、この情報システム１ａによれば、情報出力部２０が、情報出力部２０の周囲に存在する車両５０に対して移動体情報を送信する。つまり、住宅街等に通常設置されている照明装置、インターホン、宅配ボックス等の装置を用いることで、住宅街等を走行する移動体９０を検知することができるため、住宅街等での障害物による死角を減らすことができる。これにより、車両５０は、例えば、移動体情報に基づいて、走行を停止したり、発進したりする等の判断に用いることができる。 Normally, in a residential area, there are many blind spots due to obstacles, and there is no environment sensor (for example, Orbis (registered trademark) sensor) installed in the environment. However, according to this information system 1a, the information output unit 20 transmits the mobile body information to the vehicles 50 existing around the information output unit 20. That is, by using a device such as a lighting device, an intercom, and a delivery box that are usually installed in a residential area or the like, it is possible to detect the moving body 90 traveling in the residential area or the like, and thus an obstacle in the residential area or the like. The blind spot due to can be reduced. As a result, the vehicle 50 can be used, for example, to determine whether to stop traveling or start based on the moving body information.

Transmitting to the vehicle 50.
　これらにおいても、上述と同様の作用効果を奏する。 ▽ Even in these, the same effect as the above is produced.
　また、本実施の形態に係る情報システム１ａにおいて、情報出力部２０は、周囲に存在する移動体９０を検知し、検知した移動体情報を出力する検知部２１と、検知部２１が出力した移動体情報を車両５０に送信する通信部２２とを有する。 Further, in the information system 1a according to the present embodiment, the information output unit 20 detects the moving body 90 existing in the surroundings and outputs the detected moving body information, and the movement output by the detecting unit 21.

Therefore, in the information system 1a, it is possible to more appropriately assist the autonomous driving vehicle so that it can travel safely.
　（実施の形態２）
　図４は、実施の形態２に係る情報システム１ｂを例示するブロック図である。 (Embodiment 2)
FIG. 4 is a block diagram illustrating the information system 1b according to the second embodiment.

　例えば杖、名札、ＩＣカード、カードケース等はユーザが常備するものであるため、端末装置２１０は、車両５０に対してユーザの正確な移動体情報を送信することができる。また、このような端末装置２１０は、ビーコン信号の通信プロトコルだけでなく、アドホックネットワークの通信プロトコルも備えるため、施設内におけるアドホックネットワークを構成する装置とも連動できる。このように、端末装置２１０は、車両５０に対して自動運転を補助する移動体情報を送信するだけでなく、ユーザの帰宅時の照明装置１０との連動、電気錠の開閉等といった、ＩｏＴ（Ｉｎｔｅｒｎｅｔ　ｏｆ　Ｔｈｉｎｇｓ）システムを構成する。 Since, for example, a cane, a name tag, an IC card, a card case, and the like are always owned by the user, the terminal device 210 can transmit the user's accurate moving body information to the vehicle 50. Further, since such a terminal device 210 has not only the communication protocol of the beacon signal but also the communication protocol of the ad hoc network, it can be linked with the devices constituting the ad hoc network in the facility. As described above, the terminal device 210 not only transmits the moving body information for assisting the automatic driving to the vehicle 50, but also interlocks with the lighting device 10 when the user returns home, opens and closes the electric lock, and the like (IoT). Configure the Internet of Things) system.
　また、端末装置２１０は、夜に視認し易い光反射シートを備えた装置であってもよい。このため、端末装置２１０には、さらに、視認性に優れた機能を付属させてもよい。 Also, the terminal device 210 may be a device including a light reflecting sheet that is easily visible at night. Therefore, the terminal device 210 may be further provided with a function having excellent visibility.
　端末装置２１０は、移動体情報を含むビーコン信号を発する。具体的には、端末装置２１０は、端末装置２１０の位置情報、速度情報、進行方向情報、及び、種類情報を含むビーコン信号を発する。例えば、位置情報は、端末装置２１０が備えるＧＰＳ（Ｇｌｏｂａｌ　Ｐｏｓｉｔｉｏｎｉｎｇ　Ｓｙｓｔｅｍ）機能により取得してもよい。また、速度情報は、端末装置２１０が備える速度センサにより取得してもよい。さらに、進行方向情報は、端末装置２１０が備える地磁気センサにより取得してもよい。また、種類情報は、ユーザが端末装置２１０に予め入力したデータによって取得してもよい。また、端末装置２１０は、撮像装置を備えていてもよい。端末装置２１０は、撮像装置によって撮像した情報に基づいて、端末装置２１０の位置情報、速度情報、進行方向情報、及び、種類情報を割り出してもよい。 The terminal device 210 emits a beacon signal including mobile unit information. Specifically, the terminal device 210 emits a beacon signal including position information, speed information, traveling direction information, and type information of the terminal device 210. For example, the position information may be acquired by a GPS (Global Positioning System) function of the terminal device 210. The speed information may be acquired by a speed sensor included in the terminal device 210. Further, the traveling direction information may be acquired by a geomagnetic sensor included in the terminal device 210. Further, the type information may be acquired by the data previously input by the user into the terminal device 210. Further, the terminal device 210 may include an imaging device. The terminal device 210 may calculate the position information, the speed information, the traveling direction information, and the type information of the terminal device 210 based on the information captured by the imaging device.
　端末装置２１０が発するビーコン信号が届く距離に車両５０が存在する場合に、車両５０は、端末装置２１０が発するビーコン信号を受信する。車両５０は、各々の照明装置１０からの移動体情報だけでなく、移動体９０に用いられる端末装置２１０からも移動体情報を取得する。 The vehicle 50 receives the beacon signal emitted by the terminal device 210 when the vehicle 50 is present within the reach of the beacon signal emitted by the terminal device 210. The vehicle 50 acquires the mobile body information from not only the mobile body information from each of the lighting devices 10 but also the terminal device 210 used for the mobile body 90.
　［動作］
　次に、情報システム１ｂ及び情報送信方法の動作について説明する。 [motion]
Next, operations of the information system 1b and the information transmission method will be described.
　図５は、実施の形態２に係る情報システム１ｂの動作を例示するシーケンス図である。図３と同一の処理については適宜その説明を省略する。 FIG. 5 is a sequence diagram illustrating the operation of the information system 1b according to the second embodiment. Descriptions of the same processes as those in FIG. 3 will be appropriately omitted.
　図５に示すように、車両５０は、近くに端末装置２１０が近づくと、端末装置２１０が発するビーコン信号を受信する（Ｓ１１１）。端末装置２１０が常にビーコン信号を発しているため、車両５０は、ビーコン信号の受信エリアに入れば、ビーコン信号を受信する。 As shown in FIG. 5, when the terminal device 210 approaches the vehicle 50, the vehicle 50 receives the beacon signal emitted by the terminal device 210 (S111). Since the terminal device 210 constantly emits a beacon signal, the vehicle 50 receives the beacon signal when it enters the beacon signal reception area.
　また、一方で、各々の照明装置１０に搭載される情報出力部２０の検知部２１は、照明装置１０の周囲に存在する移動体９０を検知する（Ｓ１１）。 On the other hand, on the other hand, the detection unit 21 of the information output unit 20 mounted on each lighting device 10 detects the moving body 90 existing around the lighting device 10 (S11).
　次に、情報出力部２０は、当該車両５０に対して移動体情報を送信する（Ｓ１２）。車両５０は、移動体情報を受信する。そして、情報システム１ｂは、処理を終了する。 Next, the information output unit 20 transmits mobile body information to the vehicle 50 (S12). The vehicle 50 receives the mobile body information. Then, the information system 1b ends the process.
　［作用効果］
　次に、本実施の形態における情報システム１ｂ及び情報送信方法の作用効果について説明する。 [Effect]
Next, the operational effects of the information system 1b and the information transmitting method according to the present embodiment will be described.
　上述したように、本実施の形態に係る情報システム１ｂは、さらに、移動体９０に保持される端末装置２１０を備える。また、端末装置２１０は、移動体情報を含むビーコン信号を発する。そして、車両５０は、端末装置２１０が発するビーコン信号を受信する。 As described above, the information system 1b according to the present embodiment further includes the terminal device 210 held by the mobile body 90. In addition, the terminal device 210 emits a beacon signal including mobile body information. Then, the vehicle 50 receives the beacon signal emitted by the terminal device 210.
　このように、ビーコン信号によって端末装置２１０の移動体情報を取得できるため、走行中の車両５０は、カメラ又はセンサ等の検知部２１で補えない物陰からの情報を正確に把握することができる、つまり、上空から俯瞰した地図のように端末装置２１０の位置を正確に把握することができる。移動体９０と衝突しないように減速若しくは停止、又は、ビーコン信号の発信源を避けるように迂回したりするといった一連の動作をするように、車両５０にプログラムすることができる。このため、車両５０は、事故を未然に回避したりすることができる。さらに、検知部２１が取得した移動体情報と合わせることで、車両５０は、様々な環境に応じた対応を取ることができる。 As described above, since the mobile unit information of the terminal device 210 can be acquired by the beacon signal, the running vehicle 50 can accurately grasp the information from the shadow that cannot be supplemented by the detection unit 21 such as a camera or a sensor. That is, the position of the terminal device 210 can be accurately grasped like a map viewed from above. The vehicle 50 can be programmed to perform a series of actions such as decelerating or stopping so as not to collide with the moving body 90, or bypassing the source of the beacon signal. Therefore, the vehicle 50 can avoid an accident in advance. Furthermore, the vehicle 50 can take measures according to various environments by combining with the moving body information acquired by the detection unit 21.
　また、情報システム１ｂが移動体情報を車両５０に送信し、端末装置２１０がビーコン信号を送信する。このため、例えば、通信環境の悪化によって情報システム１ｂと車両５０とが通信できなくなっても、車両５０は、端末装置２１０が発するビーコン信号を受信することができる。このため、情報システム１ｂでは、車両５０に対して移動体情報を確実に送信することができる。 Also, the information system 1b transmits mobile body information to the vehicle 50, and the terminal device 210 transmits a beacon signal. Therefore, for example, even if the information system 1b and the vehicle 50 cannot communicate with each other due to the deterioration of the communication environment, the vehicle 50 can receive the beacon signal emitted from the terminal device 210. Therefore, the information system 1b can reliably transmit the mobile body information to the vehicle 50.
