Description

本発明は、電気自動車データ通信システムに係り、特に電灯線通信を利用した電気自動車および通信装置に関する。   The present invention relates to an electric vehicle data communication system, and more particularly to an electric vehicle and a communication device using power line communication.

従来の電気自動車データ通信システムの機能構成を示すブロック図を図３に示す。   FIG. 3 is a block diagram showing a functional configuration of a conventional electric vehicle data communication system.

図３において、１５は電気自動車、１６は充電器、１７は外部電力、１８はバッテリ、１９は電圧検知部、２０は電気自動車内通信部、２１は充電器内通信部、２２は電圧制御部をそれぞれ示している。電気自動車１５の内部には、バッテリ１８、電圧検知部１９および電気自動車内通信部２０を有し、バッテリ１８の出力は電圧検知部１９と接続され、電圧検知部１９の出力は電気自動車内通信部２０に接続されている。さらに、電気自動車内通信部２０は充電器内通信部２１を介して充電器１６内部の電圧制御部２２に接続され、電圧制御部２２は外部電力１７と接続され、電圧制御部２２の出力はバッテリ１８と接続されている。   In FIG. 3, 15 is an electric vehicle, 16 is a charger, 17 is external power, 18 is a battery, 19 is a voltage detection unit, 20 is a communication unit within the electric vehicle, 21 is a communication unit within the charger, and 22 is a voltage control unit. Respectively. The electric vehicle 15 includes a battery 18, a voltage detection unit 19, and an electric vehicle communication unit 20. The output of the battery 18 is connected to the voltage detection unit 19, and the output of the voltage detection unit 19 is an electric vehicle communication. Connected to the unit 20. Furthermore, the communication unit 20 in the electric vehicle is connected to the voltage control unit 22 inside the charger 16 via the communication unit 21 in the charger, the voltage control unit 22 is connected to the external power 17, and the output of the voltage control unit 22 is A battery 18 is connected.

次に動作について説明する。   Next, the operation will be described.

図３に示す従来の電気自動車データ通信システムでは、バッテリ１８の充電特性を最大限に発揮するため、充電時おけるバッテリ１８の電圧を電圧検知部１９で検知し、電気自動車内通信部２０および充電器内通信部２１を介して電圧制御部２２に電圧値とバッテリ１８の種類を通信し、電圧制御部２２ではバッテリ１８にかける電圧をバッテリ１８の種類に基づいた充電性能を最大限に発揮できる電圧値に変化させることにより、バッテリ１８の充電時における充電性能を最大限に発揮できる。   In the conventional electric vehicle data communication system shown in FIG. 3, in order to maximize the charging characteristics of the battery 18, the voltage of the battery 18 during charging is detected by the voltage detection unit 19, and the electric vehicle communication unit 20 and the charging unit are charged. The voltage value and the type of the battery 18 are communicated to the voltage control unit 22 via the in-unit communication unit 21, and the voltage control unit 22 can maximize the charging performance based on the type of the battery 18 with respect to the voltage applied to the battery 18. By changing the voltage value, the charging performance when the battery 18 is charged can be maximized.

しかしながら、上記従来の構成では伝送する情報がバッテリ１８の種類と電圧値だけということで、せっかく新たに導入した電気自動車データ通信システムの機能を活かした構成となっているとは言えず、まったくもって勿体ないという感は否めない。   However, in the above conventional configuration, the information to be transmitted is only the type and voltage value of the battery 18, so it cannot be said that the configuration of the newly introduced electric vehicle data communication system is utilized. I can't deny the feeling that it's no use.

そこで、本発明においては、電気自動車データ通信システムの機能を活かしてリアルタイムに電気自動車の管理ができ、セキュリティを向上させた電気自動車データ通信システムを提供することを目的とする。   Accordingly, an object of the present invention is to provide an electric vehicle data communication system capable of managing an electric vehicle in real time by utilizing the function of the electric vehicle data communication system and improving security.

（実施の形態１）
図１は、本発明の実施の形態１における電気自動車データ通信システムの機能構成を示すブロック図である。 (Embodiment 1)
FIG. 1 is a block diagram showing a functional configuration of an electric vehicle data communication system according to Embodiment 1 of the present invention.

図１において、１はプラグ、２はコンセント、３は電気自動車、４は充電部、５は電灯線通信部、６はカメラ、７は電灯線ネットワーク、８は他媒体ネットワーク、９はパーソナルコンピュータ、１０はゲートウェイ装置、１１はモデム装置、１２は情報配信サーバ、１３はインターネットをそれぞれ示している。   In FIG. 1, 1 is a plug, 2 is an outlet, 3 is an electric vehicle, 4 is a charging unit, 5 is a power line communication unit, 6 is a camera, 7 is a power line network, 8 is another medium network, 9 is a personal computer, Reference numeral 10 denotes a gateway device, 11 denotes a modem device, 12 denotes an information distribution server, and 13 denotes the Internet.

電灯線ネットワーク７にコンセント２を接続し、電気自動車３内部の充電部４の入力にプラグ１を接続し、コンセント２にプラグ１を差し込んで接続することにより、充電部４は商用電源からバッテリに充電することが可能となる。充電部４の入力は分岐して電灯線通信部５と接続する。宅内ではパーソナルコンピュータ９を他媒体ネットワーク８と接続し、他媒体ネットワーク８および電灯線ネットワーク７をゲートウェイ装置１０の入力に接続する。ゲートウェイ装置１０の出力はモデム装置１１の入力に接続し、モデム装置１１の出力はインターネット１３に接続し、インターネット１３を介して情報配信サーバ１２と接続している。ここで、ゲートウェイ装置１０は、電灯線ネットワーク７と他媒体ネットワーク８とをブリッジし、電灯線ネットワーク７および他媒体ネットワーク８をモデム装置１１にルーティングする機能を有する。   By connecting the outlet 2 to the power line network 7, connecting the plug 1 to the input of the charging unit 4 inside the electric vehicle 3, and connecting the plug 1 by inserting the plug 1 into the outlet 2, the charging unit 4 is connected from the commercial power source to the battery. It becomes possible to charge. The input of the charging unit 4 is branched and connected to the power line communication unit 5. At home, the personal computer 9 is connected to the other medium network 8, and the other medium network 8 and the power line network 7 are connected to the input of the gateway device 10. The output of the gateway device 10 is connected to the input of the modem device 11, and the output of the modem device 11 is connected to the Internet 13 and is connected to the information distribution server 12 via the Internet 13. Here, the gateway device 10 has a function of bridging the power line network 7 and the other medium network 8 and routing the power line network 7 and the other medium network 8 to the modem device 11.

次に、動作説明に入る。   Next, operation description will be started.

電気自動車３の充電部４によるバッテリ（図示せず）の充電開始時、電灯線通信部５からプラグ１、コンセント２、電灯線ネットワーク７、ゲートウェイ装置１０および他媒体ネットワーク８の経路で、パーソナルコンピュータ９に充電開始信号を送る。この充電開始信号を受けたパーソナルコンピュータ９では、セキュリティロックをオンにして警戒態勢に入る。ここで、電気自動車３からは、絶えず接続信号がパーソナルコンピュータ９に送られてくる。   At the start of charging of a battery (not shown) by the charging unit 4 of the electric vehicle 3, a personal computer is connected via a path from the power line communication unit 5 to the plug 1, the outlet 2, the power line network 7, the gateway device 10, and the other medium network 8. A charging start signal is sent to 9. In the personal computer 9 that has received this charge start signal, the security lock is turned on and a warning state is entered. Here, a connection signal is constantly sent from the electric vehicle 3 to the personal computer 9.

この警戒態勢時、パーソナルコンピュータ９のセキュリティロックを解除することなしにプラグ１を抜いた場合、接続信号が当然消えることになる。接続信号が途絶えた場合、電灯線ネットワーク７に接続されたカメラ６からの動画信号または静止画信号をパーソナルコンピュータ９で保存するとともに、他媒体ネットワーク８、ゲートウェイ装置１０、モデム装置１１の経路でインターネット１３を通じ、情報配信サーバ１２に警報を発する。   In this alert state, if the plug 1 is pulled out without releasing the security lock of the personal computer 9, the connection signal will naturally disappear. When the connection signal is interrupted, the moving image signal or still image signal from the camera 6 connected to the power line network 7 is stored in the personal computer 9, and the Internet is transmitted through the path of the other medium network 8, the gateway device 10, and the modem device 11. 13, an alarm is issued to the information distribution server 12.

警報が送られてきた情報配信サーバ１２では、カメラ６の画像をインターネット１３を通じて受信して現場を確認でき、確認後直接現地に向かうか警察に通報する。なお、セキュリティロックの解除信号の入力は、パーソナルコンピュータ９または電気自動車３のどちらで行っても良い。   The information distribution server 12 to which the alarm has been sent can receive the image of the camera 6 through the Internet 13 and confirm the site, and after confirming it, it goes directly to the site or reports to the police. The security lock release signal may be input by either the personal computer 9 or the electric vehicle 3.

以上の構成とすることにより、電気自動車３の宅地内でのセキュリティを大きく向上することができ、同分野で益するところが大である。   With the above configuration, the security in the residential area of the electric vehicle 3 can be greatly improved, which greatly benefits in this field.

（実施の形態２）
本発明の実施の形態２における電気自動車データ通信システムは、図１と同様の構成に加え、コンセント２に電灯線通信機能を設けたものであり、以下のように動作する。 (Embodiment 2)

電気自動車３内部の電灯線通信部５およびコンセント２には、予め同一のＩＤが振ってあり、電気自動車３のバッテリの充電開始時、プラグ１とコンセント２とを接続すると、電灯線通信によりコンセント２から電気自動車３にコンセント２のＩＤを送付する。そして、コンセント２のＩＤを受信した電気自動車３内部の電灯線通信部５では、予め振ってある電気自動車３のＩＤと比較して同じかどうかを判断する。   The same ID is assigned to the power line communication unit 5 and the outlet 2 in the electric vehicle 3 in advance. When the plug 1 and the outlet 2 are connected at the start of charging of the battery of the electric vehicle 3, the outlet is connected by power line communication. 2 sends the ID of the outlet 2 to the electric vehicle 3. Then, the power line communication unit 5 inside the electric vehicle 3 that has received the ID of the outlet 2 determines whether it is the same as the ID of the electric vehicle 3 that has been shaken in advance.

ＩＤが同じであった場合、充電部４でバッテリの充電を開始する。一方、同じでなかった場合、バッテリの充電を開始しないばかりか、誤接続が続いた場合は、電灯線ネットワーク７に接続されたカメラ６からの動画信号または静止画信号をパーソナルコンピュータ９で保存するとともに、他媒体ネットワーク８、ゲートウェイ装置１０、モデム装置１１の経路でインターネット１３を通じ、情報配信サーバ１２に警報を発する。警報が送られてきた情報配信サーバ１２では、カメラ６の画像をインターネット１３を通じて受信して現場を確認でき、確認後直接現地に向かうか警察に通報する。   When the IDs are the same, the charging unit 4 starts charging the battery. On the other hand, if they are not the same, the charging of the battery is not started, and if the incorrect connection continues, the video signal or still image signal from the camera 6 connected to the power line network 7 is stored in the personal computer 9. At the same time, an alarm is issued to the information distribution server 12 through the Internet 13 through the route of the other medium network 8, the gateway device 10, and the modem device 11. The information distribution server 12 to which the alarm has been sent can receive the image of the camera 6 through the Internet 13 and confirm the site, and after confirming it, it goes directly to the site or reports to the police.
