Description

本発明は、無線データ通信機能を有する携帯機器において、無線通信に用いるコイルを共用して、非接触充電を行う電力・信号伝送モジュール、非接触充電モジュールならびに非接触充電および信号伝送システムに関する。   The present invention relates to a power / signal transmission module, a contactless charging module, and a contactless charging and signal transmission system that perform contactless charging by sharing a coil used for wireless communication in a portable device having a wireless data communication function.

フェリカ（登録商標）などのＲＦＩＤ機能を搭載した携帯電話が広く普及しており、また、主に数百ｋＨｚ帯において電磁誘導方式を利用した携帯機器などの非接触充電システムが従来技術として知られている。   Mobile phones equipped with an RFID function such as Felica (registered trademark) are widely used, and non-contact charging systems such as portable devices using an electromagnetic induction method mainly in the several hundred kHz band are known as the prior art. ing.

非接触充電システムは、被充電対象となる携帯機器などに内蔵されている二次電池を充電する目的などに使用されており、二次電池の状態に応じて適正に充電を実施するために、二次電池の情報を一次側すなわち充電器側にフィードバックする技術が用いられている。   The non-contact charging system is used for the purpose of charging a secondary battery built in a portable device to be charged, etc., in order to properly charge according to the state of the secondary battery, A technique is used in which information of the secondary battery is fed back to the primary side, that is, the charger side.

例えば、特許文献１では、非接触式充電機器において、負荷となる二次電池の状態による一次側電流を所定の閾値と比較し、これを二次側からの信号とみなして電池の充電制御を行っている。この例のように、非接触充電における充電制御信号は一般的には通信ではなく二次側の負荷変動情報を用いている。   For example, in Patent Document 1, in a non-contact charging device, a primary side current due to a state of a secondary battery serving as a load is compared with a predetermined threshold, and this is regarded as a signal from the secondary side to control charging of the battery. Is going. As in this example, the charge control signal in non-contact charging generally uses secondary side load fluctuation information instead of communication.

また、特許文献２では、携帯端末や電子時計などの携帯電子機器において、通常の動作時および充電時でアラームなどの機能の告知方法を変える手段を用いているものであって、充電とデータ通信とは時間的に分離されている。   Patent Document 2 uses means for changing a function notification method such as an alarm during normal operation and charging in a portable electronic device such as a portable terminal or an electronic watch. And are separated in time.

また、特許文献３では、携帯端末や電子時計などの携帯電子機器において、一次側による送信で二次側に信号が誘起された状態でコイルの抵抗負荷を変動させることで低消費電力化でき、その結果二次側の負担を軽減している。   Moreover, in patent document 3, in portable electronic devices, such as a portable terminal and an electronic timepiece, power consumption can be reduced by changing the resistance load of the coil in a state where a signal is induced on the secondary side by transmission by the primary side, As a result, the burden on the secondary side is reduced.

しかしながら、従来技術において、例えば電磁誘導による無線通信と非接触電力伝送の機能を合わせ持つ機器を実現するためには、ＲＦＩＤ機能とそのための第１のコイル、充電機能とそのための第２のコイルをそれぞれ搭載することが考えられるが、第１のコイルは１３．５６ＭＨｚ帯に対応したサイズおよびターン数のもの、第２のコイルは例えば１２５ｋＨｚ帯対応のサイズおよびターン数のものがそれぞれ必要となり、携帯電話端末などコンパクトに非常に高密度に部品が実装されたデバイスにおいては本来の電話機能にかかわるアンテナの他に、上記の異なる２つのコイルを搭載するスペースを確保することは困難である。   However, in the prior art, for example, in order to realize a device having the functions of wireless communication by electromagnetic induction and contactless power transmission, the RFID function and the first coil for the function, the charging function and the second coil for the function are provided. Although it is possible to mount each of them, the first coil is required to have a size and the number of turns corresponding to the 13.56 MHz band, and the second coil is required to have a size and the number of turns corresponding to, for example, a 125 kHz band. In a device such as a telephone terminal in which components are mounted at a very high density, it is difficult to secure a space for mounting the two different coils in addition to the antenna related to the original telephone function.

仮に、充電に関わる動作周波数をＲＦＩＤ機能とあわせて１３．５６ＭＨｚで実現するなど、電磁誘導に用いるコイルを共通化した場合には省スペース化できるが、一つのコイルに通信と充電の機能を混載するために、スイッチなどにより、これらの機能を時間的に分離する必要が有り、充電と通信は同時にはできないことになる。ここで、例えばＮＦＣ（Ｎｅａｒ Ｆｉｅｌｄ Ｃｏｍｍｕｎｉｃａｔｉｏｎ）やフェリカに代表される１３．５６ＭＨｚ帯の情報通信と非接触充電とをひとつのコイルで共用化した具体的な開示はない。   If the coil used for electromagnetic induction is made common, such as realizing the operating frequency related to charging at 13.56 MHz together with the RFID function, space can be saved, but the communication and charging functions are mixed in one coil. In order to do this, it is necessary to separate these functions temporally by a switch or the like, and charging and communication cannot be performed simultaneously. Here, for example, there is no specific disclosure in which 13.56 MHz band information communication represented by NFC (Near Field Communication) and Felica and non-contact charging are shared by one coil.

さらに、非接触充電の際にコイルを共通化した上で通信によるＩＤ認証機能を用いた充電制御方法についても開示例がなく、この場合、充電器と被充電機器間でＩＤ認証を行えないため、誤って充電器に非対応機器や異物を配置した場合には過熱する恐れがあった。   Furthermore, there is no disclosure example of a charging control method using an ID authentication function by communication after using a common coil in non-contact charging, and in this case, ID authentication cannot be performed between the charger and the device to be charged. If a non-compliant device or foreign object is accidentally placed in the charger, there is a risk of overheating.

また、コイルが共用であっても充電と通信は時間的に分離されているか、時間的には同時であっても充電用と通信用のコイルとは互いに空間的に分離された異なるものであった。   In addition, even if the coils are shared, charging and communication are temporally separated, or even if they are temporally simultaneous, the charging and communication coils are spatially separated from each other. It was.

あるいは、充電に関わる動作周波数をＲＦＩＤ機能とあわせて１３．５６ＭＨｚで実現するなど、電磁誘導に用いるコイルを共通化した場合には省スペース化できるが、ひとつのコイルに通信と充電の機能を混載するため、スイッチなどにより、これらの機能を時間的に分離しなければならないという課題があった。   Alternatively, if the coil used for electromagnetic induction is shared, such as when the operating frequency related to charging is realized at 13.56 MHz in combination with the RFID function, the communication and charging functions can be combined in one coil. Therefore, there is a problem that these functions must be temporally separated by a switch or the like.

本発明は、上記の課題を解決し、省スペース化が可能で、その上、対応機器にのみ充電可能であり、さらに充電と通信が同時に実現可能な電力・信号伝送モジュール、非接触充電モジュールならびに非接触充電および信号伝送システムを提供することにある。   The present invention solves the above-mentioned problems, can save space, and can be charged only to a compatible device, and further can be charged and communicated simultaneously, a power / signal transmission module, a non-contact charging module, and It is to provide a non-contact charging and signal transmission system.

Furthermore, a non-contact charging and signal transmission system capable of simultaneously charging and communicating is realized.

The above-described non-contact charging module is provided, which includes a second oscillator that generates

また、本発明によれば、上記の電力・信号伝送モジュールと上記の非接触充電モジュールからなり、各々前記第１のコイル及び前記第２のコイルを介して互いに電磁誘導により非接触で電力伝送および信号送受信することを特徴とする非接触充電および信号伝送システムが得られる。すなわち、電力伝送と信号送受信の駆動を同期させるための共通な発振子を有する電力・信号伝送モジュール、発振子を有しない電力・信号伝送モジュールと、発振子を有する非接触充電モジュール、発振子を有しない非接触充電モジュールとの組み合わせで４組の非接触充電および信号伝送システムが得られる。   Further, according to the present invention, the power / signal transmission module and the non-contact charging module described above are configured to transmit power in a non-contact manner by electromagnetic induction through the first coil and the second coil, respectively. A contactless charging and signal transmission system characterized by transmitting and receiving signals is obtained. That is, a power / signal transmission module having a common oscillator for synchronizing drive of power transmission and signal transmission / reception, a power / signal transmission module having no oscillator, a non-contact charging module having an oscillator, and an oscillator Four sets of non-contact charging and signal transmission systems are obtained in combination with a non-contact charging module that does not have.

また、本発明によれば、上記の非接触充電モジュールに上記の電力・信号伝送モジュールのＩＤが登録され、上記の非接触充電モジュール上に上記の電力・信号伝送モジュールが配置された際、非接触通信によりデータ通信を行い、上記の電力・信号伝送モジュールのＩＤを識別し、予め上記の非接触充電モジュールに登録されたＩＤと一致した場合にのみ充電を開始する認証機能を有する上記の非接触充電および信号伝送システムが得られる。すなわち、この場合も、電力伝送と信号送受信の駆動を同期させるための共通な発振子を有する電力・信号伝送モジュール、発振子を有しない電力・信号伝送モジュールと、発振子を有する非接触充電モジュール、発振子を有しない非接触充電モジュールとの組み合わせで４組の非接触充電および信号伝送システムが得られる。   According to the present invention, when the ID of the power / signal transmission module is registered in the contactless charging module and the power / signal transmission module is disposed on the contactless charging module, The above-mentioned authentication function that performs data communication by contact communication, identifies the ID of the power / signal transmission module, and has an authentication function that starts charging only when the ID matches the ID registered in the non-contact charging module in advance.

以下、本発明の実施の形態について、図面を用いながら詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

（実施の形態１）
図１は、本発明の実施の形態１に係る非接触充電および信号伝送システムの概略図を示している。図１に示すように、本発明の実施の形態１に係る非接触充電および信号伝送システム１０は、携帯端末などの電力・信号伝送モジュール１１と、充電器などの非接触充電モジュール２１とからなり、各々のコイル、すなわち第１のコイル１６、第２のコイル２６を介して互いに電磁誘導により非接触で電力伝送および信号送受信する構成となっている。 (Embodiment 1)
FIG. 1 shows a schematic diagram of a contactless charging and signal transmission system according to Embodiment 1 of the present invention. As shown in FIG. 1, the contactless charging and signal transmission system 10 according to the first embodiment of the present invention includes a power / signal transmission module 11 such as a portable terminal and a contactless charging module 21 such as a charger. The power transmission and the signal transmission / reception are performed in a non-contact manner by electromagnetic induction through each coil, that is, the first coil 16 and the second coil 26.

図２は、本発明の実施の形態１に係る携帯機器用の電力・信号伝送モジュールの概略図を示している。図２に示すように、携帯機器用の電力・信号伝送モジュール１１は、電力伝送機能と信号送受信機能と情報処理機能を各々備え、二次電池１２の充電またはその他の負荷回路を制御するための第１の電力制御回路１３と、信号送受信を制御するための第１の信号制御・情報処理回路１４とはともに、電力伝送と信号送受信とを分離、結合する機能を有する第１の分離結合回路１５を介して単一コイルである第１のコイル１６の両端に共通に接続されている。   FIG. 2 shows a schematic diagram of a power / signal transmission module for portable equipment according to Embodiment 1 of the present invention. As shown in FIG. 2, the power / signal transmission module 11 for portable devices has a power transmission function, a signal transmission / reception function, and an information processing function, respectively, for controlling charging of the secondary battery 12 or other load circuit. Both the first power control circuit 13 and the first signal control / information processing circuit 14 for controlling signal transmission / reception have a function of separating and combining power transmission and signal transmission / reception. 15 is commonly connected to both ends of the first coil 16 which is a single coil.

図３は、本発明の実施の形態１に係る非接触充電モジュールの概略図を示している。図３に示すように、非接触充電モジュール２１は、電力伝送機能と信号送受信機能と情報処理機能を各々備え、電源部２２と、これを制御するための第２の電力制御回路２３と、信号送受信を制御するための第２の信号制御・情報処理回路２４とからなり、これらはともに電力伝送と信号送受信とを分離、結合する機能を有する第２の分離結合回路２５を介して単一コイルである第２のコイル２６の両端に共通に接続されている。   FIG. 3 shows a schematic diagram of the contactless charging module according to Embodiment 1 of the present invention. As shown in FIG. 3, the non-contact charging module 21 includes a power transmission function, a signal transmission / reception function, and an information processing function, respectively, a power supply unit 22, a second power control circuit 23 for controlling the power supply unit 22, a signal And a second signal control / information processing circuit 24 for controlling transmission / reception, both of which are connected to a single coil via a second separation / coupling circuit 25 having a function of separating and coupling power transmission and signal transmission / reception. Are commonly connected to both ends of the second coil 26.

次に、本発明について、非接触充電および信号伝送システムの動作状態における、充電および信号波形に着目して、具体的な事例を説明する。システムの構成は図１に示した構成とし、具体的な動作周波数はＮＦＣを想定した１３．５６ＭＨｚとしており、これは充電に関わる周波数も共通とした。   Next, specific examples of the present invention will be described by focusing on the charging and signal waveforms in the operation state of the non-contact charging and signal transmission system. The configuration of the system is the configuration shown in FIG. 1, and the specific operating frequency is 13.56 MHz assuming NFC, which is also the frequency related to charging.

図４に、本発明の実施の形態１に係る非接触充電および信号伝送システムのコイル両端に発生する電圧動作波形を示す。充電およびデータ通信には同一のコイルを共用し、これらは同じ周波数で実施している。   FIG. 4 shows voltage operation waveforms generated at both ends of the coil of the contactless charging and signal transmission system according to Embodiment 1 of the present invention. The same coil is shared for charging and data communication, and they are implemented at the same frequency.

図４に示すように、電圧波形６１は、ＲＦＩＤのデータ通信に関わるコイル両端にかかる電圧波形であり、充電のための伝送電圧波形でもある。つまりこれらの電圧波形も共通化されていることが特徴であり、電力伝送と信号送受信に関わる送信コイルに励起される電圧波形が同一である。時間Ｔ１は、データ通信および充電がいずれも行われておらずオフの状態である。ここで、充電の開始に当たって、充電モジュールにあらかじめ登録された被充電機器の個別ＩＤと被充電機器のＩＤを照合する。そこでは非接触通信によりデータ通信を行うことでＩＤ認証を実行し、予め非充電機器に登録されたＩＤと一致するなどの条件を満たせば充電を開始する過程を踏んでいる。時間Ｔ２は、前記認証が確認できた後に、データ通信と充電との両方が行われており、１３．５６ＭＨｚの搬送波にデータが重畳した変調波形を示している。時間Ｔ３は、充電のみ実施されている状態である。ここではデータ通信に伴う変調波形はない。時間Ｔ４ではいずれもオフ状態である。   As shown in FIG. 4, the voltage waveform 61 is a voltage waveform applied to both ends of the coil involved in RFID data communication, and is also a transmission voltage waveform for charging. In other words, these voltage waveforms are also shared, and the voltage waveforms excited in the transmission coils involved in power transmission and signal transmission / reception are the same. At time T1, neither data communication nor charging is performed, and the state is off. Here, at the start of charging, the individual ID of the device to be charged registered in the charging module in advance and the ID of the device to be charged are collated. In this case, ID authentication is performed by performing data communication by non-contact communication, and charging is started when a condition such as matching with an ID registered in advance in a non-charging device is satisfied. Time T2 indicates a modulation waveform in which both data communication and charging are performed after the authentication is confirmed, and data is superimposed on a 13.56 MHz carrier wave. Time T3 is a state in which only charging is performed. Here, there is no modulation waveform associated with data communication. At time T4, both are off.

このように、充電およびデータ通信に同一のコイルを共用し、時間的、空間的に同時に実行するために、電力伝送と信号送受信とを分離・結合する機能を有する分離結合回路を介して単一コイルの両端に共通に接続されている。このため、同一のコイルで通信中も充電可能となっている。   In this way, the same coil is shared for charging and data communication, and the power transmission and the signal transmission / reception are separated and combined with each other in order to execute simultaneously in time and space. Commonly connected to both ends of the coil. For this reason, charging is possible even during communication using the same coil.

図５は、従来例の非接触充電システムにおけるコイル両端に発生する電圧動作波形を示している。図５に示すように、電圧波形４１は、ＲＦＩＤのデータ通信に関わるコイル両端にかかる電圧波形であり、電圧波形４２は、充電のための伝送電圧波形である。時間Ｔ１は、データ通信および充電がいずれも行われておらずオフの状態である。時間Ｔ２は、データ通信および充電が同時に行われており、電圧波形４１のデータ通信は１３．５６ＭＨｚの搬送波にデータが重畳した変調波形を示し、電圧波形４２の充電は１２５ｋＨｚの動作周波数で実施されている。これらは互いに異なる回路網およびコイルによりなされるものである。時間Ｔ３では充電のみ実施している状態である。時間Ｔ４ではいずれもオフ状態である。   FIG. 5 shows voltage operation waveforms generated at both ends of the coil in the conventional contactless charging system. As shown in FIG. 5, a voltage waveform 41 is a voltage waveform applied to both ends of a coil involved in RFID data communication, and a voltage waveform 42 is a transmission voltage waveform for charging. At time T1, neither data communication nor charging is performed, and the state is off. At time T2, data communication and charging are performed at the same time, data communication of the voltage waveform 41 shows a modulation waveform in which data is superimposed on a carrier wave of 13.56 MHz, and charging of the voltage waveform 42 is performed at an operating frequency of 125 kHz. ing. These are made by different networks and coils. At time T3, only charging is performed. At time T4, both are off.

図６は、他の従来例の非接触充電システムにおけるコイル両端に発生する電圧動作波形を示している。充電およびデータ通信には同一のコイルを共用し、これらが同じ周波数帯で実施されているケースである。   FIG. 6 shows voltage operation waveforms generated at both ends of a coil in another conventional non-contact charging system. This is a case where the same coil is shared for charging and data communication, and these are implemented in the same frequency band.

図６に示すように、電圧波形５１は、ＲＦＩＤのデータ通信に関わるコイル両端にかかる電圧波形であり、電圧波形５２は、充電のための伝送電圧波形である。時間Ｔ１は、データ通信および充電がいずれも行われておらずオフの状態である。時間Ｔ２は、データ通信が行われており、電圧波形５１のデータ通信は１２５ｋＨｚの搬送波にデータが重畳した変調波形を示している。時間Ｔ３は、充電のみ実施されている状態である。時間Ｔ４ではいずれもオフ状態である。   As shown in FIG. 6, a voltage waveform 51 is a voltage waveform applied to both ends of a coil involved in RFID data communication, and a voltage waveform 52 is a transmission voltage waveform for charging. At time T1, neither data communication nor charging is performed, and the state is off. At time T2, data communication is performed, and the data communication of the voltage waveform 51 shows a modulation waveform in which data is superimposed on a 125 kHz carrier wave. Time T3 is a state in which only charging is performed. At time T4, both are off.

このように、従来例では、充電およびデータ通信に同一のコイルを共用するために、充電およびデータ通信を実行するタイミングを時間的に分離している。   As described above, in the conventional example, in order to share the same coil for charging and data communication, timings for executing charging and data communication are separated in terms of time.
