Description
本発明は、持ち運び可能な小型の装置に電力供給する充電システムに関する。 The present invention relates to a charging system for supplying power to a small portable device.
例えば、パーソナルコンピュータ、ＰＤＡ（Personal Digital（Data） Assistants）などの情報処理装置をはじめとする各種機器の小型化にともない、それらの機器を、例えば家庭用ＡＣ電源などに接続して、所定の場所で利用するだけではなく、任意の場所で利用したいという要求がある。 For example, as various devices such as personal computers and PDAs (Personal Digital (Data) Assistants) are miniaturized, such devices are connected to, for example, a household AC power source and the like. There is a demand that you want to use it in any place.
従来は、ネットワークの接続、プリンタなどの周辺機器の接続、電源アダプタの接続などがあり、持ち運ぶ為にはケーブルやアダプタを外す必要があった。 Conventionally, there are connection of a network, connection of peripheral devices such as a printer, connection of a power adapter, etc., and it has been necessary to remove a cable or an adapter in order to carry it.
最近、無線のネットワークが普及し、周辺機器もネットワーク対応化が進み、従来に比べてケーブルの接続などは少なくなったが、電源アダプタは変わらず使用されている。 Recently, wireless networks have become widespread, and peripheral devices have become compatible with the network, and the number of cable connections and the like has decreased compared to the conventional one, but power adapters are still used.
上記した持ち運び可能な装置は充電式の電池を備えており、電源の無いところでは電池で動作し、電源のあるところで充電用のアダプタと接続して充電を行うといった使用方法となる。 The portable device described above is provided with a rechargeable battery. The battery is operated when there is no power source, and charging is performed by connecting to a charging adapter when the power source is present.
通常、使用者の机などで作業するときに電源アダプタを接続して充電を行う事になるが、可搬性が利点となる装置において、持ち運びの度に電源アダプタと接続する必要がある。また、卓上作業中に電源の接続を忘れて、実際に持ち運ぶときに電池の残容量が不足したりする場合がある。 Normally, charging is performed by connecting a power adapter when working on a user's desk or the like. However, in a device that is advantageous in portability, it is necessary to connect the power adapter every time it is carried. In addition, the user may forget to connect the power supply while working on the table, and may actually run out of remaining battery capacity when carrying it.
安全性の面では、ＰＣ側のコネクタのみを抜いた場合、通電された端子が外部にさらされ、ピンなどが接点部に入り込むことでショートする危険もあるため、コンセント側も外す必要がある。しかし、コンセントの位置は通常机の下などにあり、外すのに手間がかかるため、ピンが通電された状態のまま放置される場合が多々ある。 In terms of safety, when only the connector on the PC side is removed, the energized terminal is exposed to the outside, and there is a risk of short-circuiting when the pin or the like enters the contact portion, so it is also necessary to remove the outlet side. However, since the position of the outlet is usually under the desk or the like, and it takes time to remove it, there are many cases in which the pin is left in an energized state.
本発明は、使用者が意識することなく、安全に充電可能な充電システムを提供することを目的とする。 An object of this invention is to provide the charging system which can be charged safely, without a user being conscious.
本発明は、複数の送電用コイルをもち、各々のコイルを別々に通電可能な送電システムと受電用コイルと通信機能を持つ受電システムによって構成される充電システムにおいて、送電システムの通信機と受電用システムの通信により受電用コイルの位置を特定する機能を持つ事を特徴とする。また、前記受電システムの移動による通信断または充電終了まで通信を維持することを特徴とする。 The present invention provides a power transmission system having a plurality of power transmission coils, a power transmission system capable of separately energizing each coil, a power reception coil, and a power reception system having a communication function. It has the function of specifying the position of the coil for power reception by communication of the system. Further, the communication is maintained until the communication is interrupted due to the movement of the power receiving system or the charging is completed.
本発明によれば、持ち運び装置が移動したときや充電完了したときに自動的に通電を終了するため、安全に電源のオン/オフができる。また、通信が成立しない場合は通電しないため、他の金属や導線などが卓上マット上にあっても発熱する心配は無い。 According to the present invention, since the energization is automatically terminated when the carrying device is moved or when the charging is completed, the power can be turned on / off safely. In addition, since no power is supplied when communication is not established, there is no fear of heat generation even if other metals or wires are on the table mat.
以下、本発明の実施例を図面を用いて説明する。 Embodiments of the present invention will be described below with reference to the drawings.
図１は、送電システムの卓上マットの構成を示す。送電用コイル１０１と通信手段１０２はセットでセル１０３を構成する。送電用マット１０４はセル１０３をタイル状に並べた構成となっている。
FIG. 1 shows a configuration of a desktop mat of a power transmission system. The power transmission coil 101 and the communication means 102 constitute a
図２は、卓上マット２０１にノートＰＣ２０２を置くときの状態を２次元で示している。ノートＰＣ２０２が充電可能な状態にあるとき、通信手段２０３、２０４は送電システムの通信手段と通信を行うため、信号を定期的に出力する。この信号は通信手段２０３と通信手段２０４を区別できるように特徴づけられており、かつ、信号の受信可能な有効距離は送電マットの通信手段２０５、２０６間の距離より１〜１．数番程度の微弱な信号とする。この信号を出力している状態でノートＰＣ２０２が卓上マット２０１に近づくと卓上マット２０１の通信手段２０５、２０６、２０７で信号を受信可能となり、卓上マット２０１は充電用コイルが近くにあることを検知する。 FIG. 2 shows a two-dimensional state when the notebook PC 202 is placed on the desktop mat 201. When the notebook PC 202 is in a chargeable state, the communication means 203 and 204 periodically output a signal in order to communicate with the communication means of the power transmission system. This signal is characterized so that the communication means 203 and the communication means 204 can be distinguished, and the effective distance at which the signal can be received is 1-1. It is a weak signal of several numbers. When the notebook PC 202 approaches the desktop mat 201 while outputting this signal, the signal can be received by the communication means 205, 206, 207 of the desktop mat 201, and the desktop mat 201 detects that the charging coil is nearby. To do.
卓上マット２０１は通信手段２０５、２０６で通信手段２０３の信号を受信し、通信手段２０５と通信手段２０６で受信した信号を比較する事で通信手段２０３に一番近い通信手段２０６を特定する。また、通信手段２０６、２０７では通信手段２０４の信号を受信し、通信手段２０６と通信手段２０７で受信した信号を比較する事で通信手段２０４に一番近い通信手段２０７を特定する。 The table mat 201 receives the signal of the communication unit 203 by the communication units 205 and 206, and compares the signals received by the communication unit 205 and the communication unit 206 to identify the communication unit 206 closest to the communication unit 203. Further, the communication means 206 and 207 receive the signal of the communication means 204 and compare the signals received by the communication means 206 and the communication means 207 to identify the communication means 207 closest to the communication means 204.
卓上マット２０１は前記特定された通信手段２０６、２０７の２点の間にあるセル２０８を充電用のコイルと判断し通電する。ノートＰＣ２０２の置かれた位置や向きによって２点が共に通信手段２０６となったり、通信手段２０５と通信手段２０７の様に２点間に２つのセルがはいる場合があるが、このときはあらかじめ決められた優先順位、もしくは２番目に近い通信手段の位置に応じてセルを選択し、隣り合うセルは選択しないことで送電用コイル同士が干渉しないようにする。充電が終了するまで通信手段２０３、２０４は信号を送信し続ける。
The desktop mat 201 determines that the
例えば、ノートＰＣ２０２を卓上マット上で通信手段２０５の方向に移動した場合、通信手段２０５、２０６、２０７と通信手段２０３、２０４の間の距離が変わる。このとき、通信手段２０３の一番近くにある送電側の通信手段は通信手段２０６から通信手段２０５になり、卓上マット２０１は通信手段２０５が近いと判断して通電するセルの制御を変更する。このとき、通信手段２０４に一番近い通信手段も通信手段２０７から通信手段２０６になり、同様に卓上マットは通信手段２０６が近いと判断して通電するセルの制御を変更する。常に一番近い通信手段を確認する事で卓上マット２０１上でノートＰＣ２０２が移動しても同時に通電するセルを制御してより近い位置の送電コイルが選択される。 For example, when the notebook PC 202 is moved in the direction of the communication means 205 on the desktop mat, the distance between the communication means 205, 206, 207 and the communication means 203, 204 changes. At this time, the communication means on the power transmission side closest to the communication means 203 changes from the communication means 206 to the communication means 205, and the desktop mat 201 determines that the communication means 205 is close and changes the control of the cell to be energized. At this time, the communication means closest to the communication means 204 changes from the communication means 207 to the communication means 206, and similarly, the desktop mat determines that the communication means 206 is close and changes the control of the energized cell. By always confirming the closest communication means, even if the notebook PC 202 moves on the desktop mat 201, a cell that is energized at the same time is controlled to select a power transmission coil at a closer position.
例えば、ノートＰＣ２０２を他の場所へ移動した場合、卓上マット２０１上の通信手段とノートＰＣ２０２上の通信手段との距離が有効距離以上になった時点で卓上マット２０１は充電可能な装置が無くなったとしてセル２０８への通電を停止する。
For example, when the notebook PC 202 is moved to another location, when the distance between the communication means on the desktop mat 201 and the communication means on the notebook PC 202 exceeds the effective distance, the table mat 201 has no chargeable device. As a result, energization of the
図３は、送電システムに複数の持ち運び可能な装置をおいた場合の図である。 FIG. 3 is a diagram when a plurality of portable devices are placed in the power transmission system.
卓上マット３０３上にすでにノートＰＣ３０１が置かれている場合、セル３０２に対応するセルが選択されている状態で、携帯電話３０５が置かれた場合も先に述べた手順に従ってセルを選択する。その際、セル３０２とセル３０５を区別するため、セル３０２とセル３０５は装置の違いを特定する識別可能な情報を持つ。卓上マット３０３は新たに受信した信号に含まれる情報が、すでに充電中の装置と違う場合にのみセルに通電を行う。
When the notebook PC 301 is already placed on the
以上説明したように、本発明は、送電用コイルは複数存在し、それぞれ独立に通電のオン／オフができる。卓上マットと持ち運び可能な装置は装置がおかれた場所で通信を行い、持ち運び可能な装置/受電用コイルの位置を特定する。卓上マットは受電用コイルに一番近い位置の送電用のコイルに通電し、電磁誘導式の充電を行う。必要な送電コイルのみに通電する事で使用者は充電を意識せず、マットの上に置くだけで充電開始できる。 As described above, according to the present invention, there are a plurality of power transmission coils, and each can be turned on / off independently. The tabletop mat and portable device communicate with where the device is located to locate the portable device / power receiving coil. The desktop mat energizes the power transmission coil closest to the power receiving coil and performs electromagnetic induction charging. By energizing only the necessary power transmission coil, the user is not aware of charging and can start charging simply by placing it on the mat.
送電用システム／受電用システムの通信手段は充電が続く間は定期的に通信を行い持ち運び可能な装置があることを確認する。充電途中で装置が移動した場合、送電用システムと受電用システムの間の通信が切れ、送電用システムは充電が終了したと判断して、対応する送電用コイルの通電をオフにする。 The communication means of the power transmission system / power reception system periodically communicates while charging continues to confirm that there is a portable device. When the device moves during charging, communication between the power transmission system and the power reception system is cut off, and the power transmission system determines that charging has been completed, and turns off the energization of the corresponding power transmission coil.
また、持ち運び可能な装置の充電が完了した場合、受電用システムの通信手段は通信を終了する。送電システムの通信手段により通信の切れたことを検知した卓上マットは充電が終了したと判断して、対応する送電用コイルの通電を終了する。 In addition, when charging of the portable device is completed, the communication unit of the power receiving system ends the communication. The desktop mat that has detected that the communication has been interrupted by the communication means of the power transmission system determines that charging has been completed, and ends energization of the corresponding power transmission coil.
