水素燃料自動車４には、自動車側の情報を充填機側に提供する情報通信装置１４が設けられている。自動車側の情報としては、例えば、タンクの温度、圧力、容積、充填率、水素漏洩の有無などを挙げることができる。
セルフ充填機２には、情報通信装置１４から自動車側の情報を取得する情報取得装置１５が設けられている。 The hydrogen fuel vehicle 4 is provided with an information communication device 14 that provides information on the vehicle side to the filling machine side. Examples of information on the automobile side include tank temperature, pressure, volume, filling rate, presence or absence of hydrogen leakage, and the like.
The self-filling machine 2 is provided with an information acquisition device 15 that acquires information on the vehicle side from the information communication device 14.

The information communication device 14 and the information acquisition device 15 may be connected by inserting the filling nozzle 3 of the self-filling machine 2 into the filling port of the hydrogen fuel vehicle 4.

充填許可／禁止指令装置１３は、情報取得装置１５により取得した自動車側の情報に基づいてセルフ充填機２による充填を許可又は禁止することができる。具体的には、セルフ充填機２側の情報取得装置１５により取得した自動車側の情報が、前記通信部１１ｃ〜１３ｃと同様の通信部１６により、監視装置６側のバルブ制御回路１３ｂに伝送されるように構成されている。従って、自動車側の情報に基づいて、バルブ制御回路１３ｂにより、バルブ１３ａを開閉制御することで、充填を許可又は禁止できる。   The filling permission / prohibition command device 13 can permit or prohibit filling by the self-filling machine 2 based on the information on the vehicle side acquired by the information acquisition device 15. Specifically, the vehicle-side information acquired by the information acquisition device 15 on the self-filling machine 2 side is transmitted to the valve control circuit 13b on the monitoring device 6 side by the communication unit 16 similar to the communication units 11c to 13c. It is comprised so that. Therefore, filling can be permitted or prohibited by controlling the opening and closing of the valve 13a by the valve control circuit 13b based on the information on the automobile side.

セルフ充填システムのセルフ充填機２は、タッチパネル式の水素充填のオーダー機を備え、利用者は基本的には画面表示と音声ガイダンスとに従って充填作業を行うことができるが、本実施形態のセルフ充填システムは、画像監視装置１１、通話装置１２、及び、充填許可／禁止指令装置１３を備えることで、次のような作用効果が得られる。   The self-filling machine 2 of the self-filling system is equipped with a touch panel type hydrogen filling ordering machine, and the user can basically perform the filling work according to the screen display and voice guidance. Since the system includes the image monitoring device 11, the communication device 12, and the filling permission / prohibition command device 13, the following operational effects can be obtained.

利用者からの問い合わせに応じて、充填を許可したり、充填方法を口頭で詳しく説明したりすることができる。
また、充填中は、指導員がディスプレイにて監視することにより、適宜、利用者を支援することができる。
また、充填中の利用者の挙動を監視し、危険を感じたり、異常な状況の場合には、充填を禁止することができる。
従って、何らかのトラブルを生じた場合でも、遠隔といえども有資格者が適切に対応することができる。 In response to an inquiry from the user, filling can be permitted, or the filling method can be verbally explained in detail.
In addition, during filling, the instructor can appropriately assist the user by monitoring on the display.
Also, the behavior of the user during filling can be monitored, and filling can be prohibited in the case of feeling a danger or an abnormal situation.
Therefore, even if some trouble occurs, a qualified person can appropriately respond even if it is remote.

また、本実施形態のセルフ充填システムでは、画像監視装置１１は、水素火炎を可視化できるカメラ１１ｅと、このカメラ１１ｅによる可視化画像に基づいて水素火炎を検知する水素火炎検知部（画像処理回路１１ｄに内蔵）とを備え、充填許可／禁止指令装置１３は、水素火炎検知部からの水素火炎検知信号に基づいて自動的にセルフ充填機２による充填を禁止できる構成である。
このように、水素火炎を可視化して、これを検知し、自動的に充填を禁止するので、安全性を更に向上させることが可能となる。 Further, in the self-filling system of the present embodiment, the image monitoring device 11 includes a camera 11e that can visualize the hydrogen flame, and a hydrogen flame detection unit (in the image processing circuit 11d) that detects the hydrogen flame based on the image visualized by the camera 11e. The filling permission / prohibition command device 13 is configured to automatically prohibit filling by the self-filling machine 2 based on a hydrogen flame detection signal from the hydrogen flame detection unit.
As described above, the hydrogen flame is visualized, detected, and automatically charged, so that the safety can be further improved.

また、本実施形態のセルフ充填システムは、水素燃料自動車４に搭載されて自動車側の情報を充填機側に提供する情報通信装置１４から、自動車側の情報を取得する情報取得装置１５を更に含んで構成され、充填許可／禁止指令装置１３は、情報取得装置１５により取得した自動車側の情報に基づいてセルフ充填機２による充填を許可又は禁止できる構成である。
このように、自動車側の情報（例えば、タンクの温度、圧力、容積、充填率、水素漏洩の有無など）を取得することで、充填を許可又は禁止したり、充填中にきめ細かく流量制御することができる。従って、安全性をより一層向上させることが可能となるだけでなく、いわゆる「通信充填」により、充填の高速化、効率化を図ることも可能となる。自動車側の情報を取得できない場合は、低流量での流量一定充填となり、充填に時間がかかるからである。 In addition, the self-charging system of the present embodiment further includes an information acquisition device 15 that acquires information on the vehicle side from an information communication device 14 that is mounted on the hydrogen fuel vehicle 4 and provides information on the vehicle side to the filling machine side. The filling permission / prohibition command device 13 is configured to permit or prohibit filling by the self-filling machine 2 based on information on the vehicle side acquired by the information acquisition device 15.
In this way, by acquiring information on the vehicle side (for example, tank temperature, pressure, volume, filling rate, presence or absence of hydrogen leakage, etc.), filling is permitted or prohibited, and fine flow control is performed during filling. Can do. Therefore, not only can the safety be improved further, but also so-called “communication filling” can increase the speed and efficiency of filling. This is because when the information on the automobile side cannot be acquired, the flow rate is constantly filled at a low flow rate, and filling takes time.

また、セルフ充填エリア１には、水素燃料自動車４のナンバーを読取るナンバー読取装置１７が備えられている。ナンバー読取装置１７により取得したナンバー情報は、前記通信部１１ｃ〜１３ｃと同様の通信部１８により、監視施設５の監視装置６側の充填履歴報知装置１７に伝送される。   Further, the self-filling area 1 is provided with a number reading device 17 for reading the number of the hydrogen fuel automobile 4. The number information acquired by the number reading device 17 is transmitted to the filling history notification device 17 on the monitoring device 6 side of the monitoring facility 5 by the communication unit 18 similar to the communication units 11c to 13c.

充填履歴報知装置１７は、ナンバーごとに積算充填回数などの充填履歴を記憶する記憶部を有していて、読取ったナンバーに基づいて、当該ナンバーの充填履歴を更新する一方、その充填履歴を画面表示等により指導員に報知する。
指導員に報知する充填履歴には、充填履歴（積算充填回数）そのものの他、充填履歴（積算充填回数）からコンピュータが判断した指導の必要性（例えば、積算充填回数＜所定値の場合に、要指導）を含む。 The filling history notification device 17 has a storage unit for storing a filling history such as the cumulative number of fillings for each number, and updates the filling history of the number based on the read number, while displaying the filling history on the screen. Notify the instructor by display.
In addition to the filling history (total number of fillings) itself, the filling history to be notified to the instructor is necessary for guidance determined by the computer from the filling history (total number of fillings) (for example, when the cumulative number of fillings is less than a predetermined value). Instruction).

このようなナンバー読取装置１７及び充填履歴報知装置１９を備えることで、充填履歴に応じた適切な指導が可能となる。   Providing such a number reading device 17 and a filling history notifying device 19 makes it possible to provide appropriate guidance according to the filling history.

尚、図示の実施形態はあくまで本発明を例示するものであり、本発明は、説明した実施形態により直接的に示されるものに加え、特許請求の範囲内で当業者によりなされる各種の改良・変更を包含するものであることは言うまでもない。   The illustrated embodiments are merely examples of the present invention, and the present invention is not limited to those directly described by the described embodiments, and various improvements and modifications made by those skilled in the art within the scope of the claims. Needless to say, it encompasses changes.
