通信端末３は、例えば、携帯電話機からなり、携帯電話網を経由してネットワーク４に接続し、ネットワーク４経由で充電設備管理装置１との間でデータ通信を行う。但し、通信端末３は携帯電話機に限定されず、ネットワーク４を経由してデータ通信する機能を有したパーソナルコンピュータやカーナビゲーションシステムなどであっても構わない。   The communication terminal 3 is composed of, for example, a mobile phone, is connected to the network 4 via the mobile phone network, and performs data communication with the charging facility management apparatus 1 via the network 4. However, the communication terminal 3 is not limited to the mobile phone, and may be a personal computer or a car navigation system having a function of performing data communication via the network 4.

次に、新たに充電スタンド２が設置された場合の充電設備管理装置１及び充電設備管理システムの動作を説明する。まず、充電スタンド２が新たに設置されると、それらの充電スタンド２の記憶部23に充電設備情報が記憶(登録)される。ここで、各充電スタンド２の充電設備情報は、例えば、登録用のコンピュータ(図示せず)からネットワーク４経由で親機に送られ、親機から通信ケーブルLsを介して子機に転送される。そして、親機及び子機の記憶部23に充電設備情報が登録(記憶)される。さらに親機の制御部20は、親機自身及び各子機の記憶部23に登録された充電設備情報を通信部23よりネットワーク４経由で充電設備管理装置１へ送信する。   Next, operations of the charging facility management device 1 and the charging facility management system when the charging station 2 is newly installed will be described. First, when charging stations 2 are newly installed, charging facility information is stored (registered) in the storage unit 23 of those charging stations 2. Here, the charging facility information of each charging station 2 is, for example, sent from a registration computer (not shown) to the parent device via the network 4 and transferred from the parent device to the child device via the communication cable Ls. . Then, charging facility information is registered (stored) in the storage unit 23 of the parent device and the child device. Furthermore, the control unit 20 of the parent device transmits the charging facility information registered in the storage unit 23 of the parent device itself and each child device from the communication unit 23 to the charging facility management apparatus 1 via the network 4.

充電設備管理装置１の制御部10は、通信部11で受信した充電設備情報を充電スタンド２(親機及び子機)の識別符号と対応付けて記憶部12に記憶(登録)する。ここで、上述したように充電設備情報には各充電スタンド２の利用状況が含まれているが、この利用状況は時々刻々と変化する。したがって、本実施形態における充電スタンド２の制御部20は、定期的(例えば、５分〜１０分毎)に利用状況の情報(使用又は未使用)を充電設備管理装置１へ送信している。そして、充電設備管理装置１の制御部10は、記憶部12に記憶されている充電設備情報のうちで各充電スタンド２の利用状況の情報を、各充電スタンド２から定期的に送られてくる最新の利用状況の情報に更新する。ここで、充電設備管理装置１の制御部10は、何れかの充電スタンド２から充電設備情報が送信されてこない期間が所定のしきい値(例えば、24時間〜数日間)を超えた場合に当該充電スタンド２の充電設備情報を記憶部12から削除する。つまり、長期間に亘って充電設備情報が送信されてこなければ、当該充電スタンド２が故障あるいは撤去されたとみなし、そのような充電スタンド２の充電設備情報を削除することにより、誤った情報が利用者に提供されることを防いでいる。   The control unit 10 of the charging facility management apparatus 1 stores (registers) the charging facility information received by the communication unit 11 in the storage unit 12 in association with the identification code of the charging stand 2 (master unit and slave unit). Here, as described above, the charging facility information includes the usage status of each charging stand 2, but this usage status changes from moment to moment. Therefore, the control unit 20 of the charging station 2 in the present embodiment transmits usage status information (used or unused) to the charging facility management apparatus 1 periodically (for example, every 5 to 10 minutes). Then, the control unit 10 of the charging facility management apparatus 1 periodically sends information on the usage status of each charging station 2 among the charging facility information stored in the storage unit 12 from each charging station 2. Update to the latest usage information. Here, the control part 10 of the charging equipment management apparatus 1 is when the period when charging equipment information is not transmitted from any charging stand 2 exceeds a predetermined threshold value (for example, 24 hours to several days). The charging facility information of the charging station 2 is deleted from the storage unit 12. In other words, if charging facility information is not transmitted over a long period of time, it is considered that the charging station 2 is broken or removed, and incorrect information is used by deleting the charging facility information of the charging station 2. It is prevented from being offered to a person.

次に、充電設備管理装置１から利用者の通信端末３に充電設備情報を提供する際の動作について説明する。但し、以下の説明では、通信端末３がGlobal Positioning System(全地球測位システム)による測位機能を有しているものとする。   Next, the operation | movement at the time of providing charging equipment information from the charging equipment management apparatus 1 to a user's communication terminal 3 is demonstrated. However, in the following description, it is assumed that the communication terminal 3 has a positioning function based on the Global Positioning System (global positioning system).

充電設備管理装置１の制御部10はウェブサーバ機能を搭載しており、記憶部12に記憶している充電設備情報を検索するためのウェブページをネットワーク４上に公開している。但し、ウェブページへのアクセスを特定の利用者(例えば、会員登録している利用者や特定の企業の社員など)のみに限定する場合、利用者IDとパスワードで認証された前記特定の利用者のみに前記ウェブページへのアクセスが許可される。   The control unit 10 of the charging facility management apparatus 1 has a web server function, and publishes a web page on the network 4 for searching for charging facility information stored in the storage unit 12. However, when the access to the web page is limited to specific users (for example, registered users or employees of specific companies), the specific user authenticated with the user ID and password Only to access the web page.

そして、利用者の通信端末３から前記ウェブページにアクセスされ、当該ウェブページ内の検索ボックスに所定の検索条件が入力される。検索条件としては、例えば、予め登録されている地域(市町村など)や、あるいは通信端末３で測位された現在位置から半径５キロメートルの範囲などが考えられる。なお、この検索条件が情報提供の要求として通信端末３から充電設備管理装置１に送信される。   And the said web page is accessed from a user's communication terminal 3, and a predetermined search condition is input into the search box in the said web page. As a search condition, for example, a pre-registered area (such as a municipality) or a range having a radius of 5 kilometers from the current position measured by the communication terminal 3 can be considered. This search condition is transmitted from the communication terminal 3 to the charging facility management apparatus 1 as a request for providing information.

充電設備管理装置１の制御部10は、記憶部12に記憶されている充電設備情報の中から検索条件に該当する充電設備情報を検索し、その検索結果を通信部11より通信端末３へ送信させる。通信端末３では、充電設備管理装置１から送信される検索結果を表示デバイス(液晶ディスプレイ)の画面に表示する。このとき、通信端末３の画面には、少なくとも充電スタンド２の所在地、利用料金、利用状況などの充電設備情報が表示される。ここで、各充電スタンド２の利用状況が定期的に更新されているので、通信端末３の画面に表示される利用状況の情報により、どこの充電スタンド２が空いているかということを利用者が的確に知ることができる。   The control unit 10 of the charging facility management device 1 searches the charging facility information stored in the storage unit 12 for charging facility information corresponding to the search condition, and transmits the search result to the communication terminal 3 from the communication unit 11. Let In the communication terminal 3, the search result transmitted from the charging facility management apparatus 1 is displayed on the screen of a display device (liquid crystal display). At this time, at least the charging facility information such as the location of the charging station 2, the usage fee, and the usage status is displayed on the screen of the communication terminal 3. Here, since the usage status of each charging station 2 is regularly updated, the user can determine which charging station 2 is free according to the usage status information displayed on the screen of the communication terminal 3. Know exactly.

ところで、各充電スタンド２の充電設備情報をコンピュータを利用して充電設備管理装置１に登録することも可能である。しかしながら、全ての充電スタンド２の充電設備情報をコンピュータから登録することは、登録作業の手間と作業ミスが生じやすくなる虞がある。これに対して本実施形態では、各充電スタンド２から送信される充電設備情報を充電設備管理装置１が記憶部12に記憶しているので、登録作業の手間が少なくなるとともに作業ミスが生じ難くなるという利点がある。   By the way, the charging facility information of each charging station 2 can be registered in the charging facility management apparatus 1 using a computer. However, registering the charging facility information of all the charging stations 2 from the computer may easily cause trouble of registration work and work mistakes. On the other hand, in this embodiment, since the charging equipment management apparatus 1 has memorize | stored the charging equipment information transmitted from each charging stand 2 in the memory | storage part 12, work of registration work reduces and it is hard to produce a work mistake. There is an advantage of becoming.
