Abstract

PROBLEM TO BE SOLVED: To provide a non-contact signaling device capable of switching to a plurality of impedance matching conditions, and of suppressing increase in the number of components.SOLUTION: A non-contact signaling device has a matching circuit part 2, and a matching changeover switch part 21 is incorporated in the matching circuit part 2. The matching changeover switch part 21 is configured by connecting a semiconductor switch between two lines via a capacitor, for example. When the semiconductor switch is in a conduction state, an electrostatic capacitance is generated between the two lines by the capacitor connected between the two lines. When the semiconductor switch is in a cut-off state, the two lines becomes almost an open state, and electrostatic capacitance is hardly generated. That is, the electrostatic capacitance between the two lines is switched by the semiconductor switch, and a matching state of the whole matching circuit part 2 can be switched.

特許文献１のようにアンテナより整合回路を介して複数の回路モジュールを接続する構成では、各々の回路モジュールでインピーダンス整合条件が異なる場合が多く、単一の整合回路では十分なインピーダンス整合が図れないという課題がある。   In a configuration in which a plurality of circuit modules are connected from an antenna via a matching circuit as in Patent Document 1, impedance matching conditions are often different for each circuit module, and sufficient impedance matching cannot be achieved with a single matching circuit. There is a problem.

そこで、特許文献２のようにインピーダンス整合条件毎に整合回路を設け、スイッチで切り替える構成とすると、整合回路の部品点数が増加するという課題がある。   Therefore, if a matching circuit is provided for each impedance matching condition and switched by a switch as in Patent Document 2, there is a problem that the number of parts of the matching circuit increases.

すなわち本発明は、インピーダンス整合条件の異なる複数の回路モジュールが整合回路に接続された場合でも、整合回路の部品点数の増加を抑えつつも、各々の回路モジュールとのインピーダンス整合を行うことが可能である非接触信号伝送装置の提供を目的とする。   That is, according to the present invention, even when a plurality of circuit modules having different impedance matching conditions are connected to the matching circuit, impedance matching with each circuit module can be performed while suppressing an increase in the number of parts of the matching circuit. An object is to provide a non-contact signal transmission device.

上記課題を本発明は、外部機器と非接触で通信、若しくは電力伝送、又は通信及び電力伝送を行うアンテナ部と、第１整合状態と第２整合状態を切り替える整合切替スイッチ部を有する整合回路部と、少なくとも１つの回路モジュール部を有する第１回路モジュール群と、少なくとも１つの回路モジュール部を有する第２回路モジュール群を有する回路モジュール集合体を備え、前記アンテナ部は、前記整合回路部と接続され、前記回路モジュール集合体は、それぞれ前記整合回路部と接続され、第１の信号により前記アンテナ部を介して前記外部機器と通信、若しくは電力伝送、又は通信及び電力伝送をする場合には、前記整合切替スイッチ部は、前記整合回路部を前記第１整合状態に切り替え、前記第１整合状態にある前記整合回路部により前記アンテナ部と、前記第１回路モジュール群のインピーダンスが整合し、第２の信号により前記アンテナ部を介して前記外部機器と通信、若しくは電力伝送、又は通信及び電力伝送をする場合には、前記整合切替スイッチ部は、前記整合回路部を前記第２整合状態に切り替え、前記第２整合状態にある前記整合回路部により前記アンテナ部と、前記第２回路モジュール群のインピーダンスが整合する非接触信号伝送装置により解決することができる。   To solve the above-described problems, the present invention provides a matching circuit unit including an antenna unit that performs non-contact communication, power transmission, or communication and power transmission with an external device, and a matching changeover switch unit that switches between a first matching state and a second matching state. And a circuit module assembly having a first circuit module group having at least one circuit module part and a second circuit module group having at least one circuit module part, wherein the antenna part is connected to the matching circuit part The circuit module assembly is connected to the matching circuit unit, and communicates with the external device via the antenna unit by the first signal, or performs power transmission, or communication and power transmission. The matching switching switch unit switches the matching circuit unit to the first matching state, and switches the matching circuit unit to the matching circuit unit in the first matching state. When the antenna unit and the impedance of the first circuit module group are matched and the second signal communicates with the external device through the antenna unit, or transmits power, or communicates and transmits power, The matching changeover switch unit switches the matching circuit unit to the second matching state, and the impedance of the antenna unit and the second circuit module group is matched by the matching circuit unit in the second matching state. This can be solved by a signal transmission device.

ここでの電力伝送とは、非接触信号伝送装置より伝送先へ電力を伝送する場合と、伝送先より非接触信号伝送装置へ電力を伝送する場合のいずれも含むことを意味する。   The power transmission here means that both the case of transmitting power from the non-contact signal transmission device to the transmission destination and the case of transmitting power from the transmission destination to the non-contact signal transmission device are included.

また、上記非接触信号伝送装置のうち、外部機器と前記アンテナ部を介して非接触で通信信号の送受信及び受電を行う非接触受電装置であって、前記第１の信号とは通信信号であり、前記第２の信号とは電力伝送信号であり、前記第１回路モジュール群は、信号送信部、信号受信部を有し、前記第２回路モジュール群は、電力受電部、及び負荷変調通信部を有していることが望ましい。   Of the non-contact signal transmission apparatus, a non-contact power receiving apparatus that performs transmission / reception and reception of communication signals in a non-contact manner with an external device via the antenna unit, wherein the first signal is a communication signal. The second signal is a power transmission signal, the first circuit module group includes a signal transmission unit and a signal reception unit, and the second circuit module group includes a power reception unit and a load modulation communication unit. It is desirable to have

信号送信部と信号受信部はインピーダンス整合条件が近いことから第１回路モジュール群として構成し、負荷変調通信部と電力受電部はインピーダンス整合条件の範囲が広いため第２回路モジュール群として構成している。   The signal transmission unit and the signal reception unit are configured as a first circuit module group because impedance matching conditions are close, and the load modulation communication unit and the power reception unit are configured as a second circuit module group because the range of impedance matching conditions is wide. Yes.

また、前記負荷変調通信部の入出力インピーダンスは、前記信号送信部及び前記信号受信部の入出力インピーダンスよりも高いことが望ましい。   The input / output impedance of the load modulation communication unit is preferably higher than the input / output impedances of the signal transmission unit and the signal reception unit.

前記整合回路部と、前記負荷変調通信部の間に半導体スイッチ部が接続され、前記電力受電部が前記アンテナ部より受電する場合には、前記半導体スイッチ部が遮断状態となり、前記電力受電部が前記アンテナ部より受電しない場合には、前記半導体スイッチ部が遮断状態となることが望ましい。   When a semiconductor switch unit is connected between the matching circuit unit and the load modulation communication unit, and the power receiving unit receives power from the antenna unit, the semiconductor switch unit is cut off, and the power receiving unit When power is not received from the antenna unit, it is desirable that the semiconductor switch unit is in a cut-off state.

また、前記整合回路部と、前記信号送信部及び前記信号受信部の間に半導体スイッチ部が接続され、前記整合切替スイッチ部が、前記第１の整合状態に前記整合回路部を切り替えた場合には、前記半導体スイッチ部は導通状態となり、前記整合切替スイッチ部が、前記第２の整合状態に前記整合回路部を切り替えた場合には、前記半導体スイッチ部は遮断状態となることが望ましい。   Further, when a semiconductor switch unit is connected between the matching circuit unit and the signal transmitting unit and the signal receiving unit, and the matching switching switch unit switches the matching circuit unit to the first matching state. Preferably, the semiconductor switch unit is in a conductive state, and the semiconductor switch unit is in a cut-off state when the matching switching switch unit switches the matching circuit unit to the second matching state.

信号送受信回路部は、特に電力伝送信号による過剰な電力から保護する必要性があるため、半導体スイッチ部により遮断することで万全な保護を行う。   Since the signal transmission / reception circuit unit needs to be protected from excessive power due to the power transmission signal in particular, the signal transmission / reception circuit unit is fully protected by being cut off by the semiconductor switch unit.

本発明により、整合回路内部に整合切替スイッチ部を設け、整合回路自体のインピーダンス整合状態を切り替えることにより、部品点数の増加を抑えつつ、複数のインピーダンス整合条件に適合可能な非接触信号伝送装置とすることができる。   According to the present invention, there is provided a non-contact signal transmission device capable of adapting to a plurality of impedance matching conditions while suppressing an increase in the number of parts by providing a matching changeover switch portion inside the matching circuit and switching an impedance matching state of the matching circuit itself. can do.

さらに、電力伝送信号による過剰な電力を半導体スイッチ部により遮断することで、信号送受信回路部及び負荷変調通信部の万全な保護を行うことができる。   Furthermore, the signal transmission / reception circuit unit and the load modulation communication unit can be fully protected by shutting off excessive power due to the power transmission signal by the semiconductor switch unit.

図１は、本発明における実施形態１に係る非接触充電装置のブロック回路図である。 (Embodiment 1)
FIG. 1 is a block circuit diagram of a contactless charging apparatus according to Embodiment 1 of the present invention.

本実施形態における非接触充電装置は、外部の非接触送電装置等と、非接触で電力の受電、及び信号の送受信を行うループコイル状のアンテナ部１を有する。   The contactless charging device in the present embodiment includes an external contactless power transmission device and the like, and a loop coil-shaped antenna unit 1 that receives power and transmits / receives signals in a contactless manner.

また、整合回路部２を有し、整合回路部２の内部には整合切替スイッチ部２１を内蔵している。   In addition, the matching circuit unit 2 is provided, and the matching switch unit 21 is built in the matching circuit unit 2.

整合切替スイッチ部２１は、例えば、２つのライン間にコンデンサを介して半導体スイッチが接続されることで構成される。   The matching changeover switch unit 21 is configured, for example, by connecting a semiconductor switch via a capacitor between two lines.

半導体スイッチが導通状態となれば、２つのライン間に接続されたコンデンサにより、２つのライン間に静電容量を生じさせる。   When the semiconductor switch becomes conductive, a capacitor connected between the two lines generates a capacitance between the two lines.

半導体スイッチが遮断状態となれば、２つのライン間は、ほぼ開放状態となり、ほとんど静電容量は生じない。   If the semiconductor switch is cut off, the two lines are almost open and almost no capacitance is generated.

すなわち、半導体スイッチにより、２つのライン間の静電容量が切り替わり、整合回路部２全体の整合状態を切り替えることができる。   That is, the capacitance between the two lines is switched by the semiconductor switch, and the matching state of the entire matching circuit unit 2 can be switched.

また、負荷変調通信部３１、送信部３２、受信部３３による通信部３を構成している。   In addition, the communication unit 3 includes the load modulation communication unit 31, the transmission unit 32, and the reception unit 33.

また、整流回路部４１、直流電圧変換部４２、充電制御部４３、二次電池４４による電力受電部４を構成している。   Moreover, the power receiving part 4 by the rectifier circuit part 41, the DC voltage conversion part 42, the charge control part 43, and the secondary battery 44 is comprised.

負荷変調通信部３１は、直列コンデンサ、共通回路部２２を介してアンテナ部１に接続されている。   The load modulation communication unit 31 is connected to the antenna unit 1 via a series capacitor and a common circuit unit 22.

送信部３２は、整合化部２３、整合切替スイッチ部２１、直列コンデンサ、共通回路部２２を介してアンテナ部１に接続されている。   The transmission unit 32 is connected to the antenna unit 1 via the matching unit 23, the matching changeover switch unit 21, the series capacitor, and the common circuit unit 22.

受信部３３は、ローパスフィルタ部２４、共通回路部２２を介してアンテナ部１に接続されている。   The receiving unit 33 is connected to the antenna unit 1 through the low-pass filter unit 24 and the common circuit unit 22.

電力受電部４は、共通回路部２２を介してアンテナ部１に接続されている。   The power receiving unit 4 is connected to the antenna unit 1 through the common circuit unit 22.

すなわち、いずれも共通回路部２２を介してアンテナ部１に接続されており、整合切替スイッチ部２１によるライン間静電容量切り替えの影響は、全てのインピーダンス整合状態に影響を与えている。   That is, both are connected to the antenna unit 1 via the common circuit unit 22, and the influence of the line-to-line capacitance switching by the matching switching switch unit 21 affects all impedance matching states.

ここで、送信部３２、受信部３３を第１回路モジュール群とし、電力受電部４と負荷変調通信部３１を第２回路モジュール群とする。   Here, the transmission unit 32 and the reception unit 33 are set as a first circuit module group, and the power receiving unit 4 and the load modulation communication unit 31 are set as a second circuit module group.

整合切替スイッチ部２１の半導体スイッチが導通状態にある場合は、第１回路モジュール群とアンテナ部１がインピーダンス整合し、第２回路モジュール群とアンテナ部１がインピーダンス整合から外れるよう、予め整合回路部２を調整しておく。   When the semiconductor switch of the matching changeover switch unit 21 is in a conductive state, the matching circuit unit is previously set so that the first circuit module group and the antenna unit 1 are impedance matched and the second circuit module group and the antenna unit 1 are out of impedance matching. 2 is adjusted.

一方、整合切替スイッチ部２１の半導体スイッチが遮断状態にある場合は、第１回路モジュール群とアンテナ部１がインピーダンス整合から外れ、第２回路モジュール群とアンテナ部１がインピーダンス整合するよう、予め整合回路部２を調整しておく。   On the other hand, when the semiconductor switch of the matching changeover switch unit 21 is in the cut-off state, matching is performed in advance so that the first circuit module group and the antenna unit 1 are out of impedance matching, and the second circuit module group and the antenna unit 1 are impedance matched. The circuit unit 2 is adjusted.

まず、アンテナ部１が外部と信号を送受信する場合は、半導体スイッチを導通状態とする。   First, when the antenna unit 1 transmits / receives a signal to / from the outside, the semiconductor switch is turned on.

これにより、第１回路モジュール群とアンテナ部１はインピーダンス整合するため、通信信号の反射、減衰を最小限のものとすることができる。   Thereby, since the first circuit module group and the antenna unit 1 are impedance matched, reflection and attenuation of the communication signal can be minimized.

また、第２回路モジュール群とアンテナ部１はインピーダンス整合から外れるため、電力受電部４のインピーダンスによる通信信号減衰等の影響を防ぐことができる。   Further, since the second circuit module group and the antenna unit 1 are out of impedance matching, it is possible to prevent the influence of communication signal attenuation or the like due to the impedance of the power receiving unit 4.

一方、アンテナ部１が外部より非接触で電力を受電する場合は、半導体スイッチを遮断状態とする。   On the other hand, when the antenna unit 1 receives power from the outside in a non-contact manner, the semiconductor switch is turned off.

これにより、第１回路モジュール群とアンテナ部１はインピーダンス整合から外れるため、電力信号による過剰な電圧が送信部３２、受信部３３に伝わることを防止できる。   Thereby, since the first circuit module group and the antenna unit 1 are out of impedance matching, it is possible to prevent an excessive voltage due to the power signal from being transmitted to the transmission unit 32 and the reception unit 33.

また、第２回路モジュール群とアンテナ部１はインピーダンス整合するため、アンテナ部１より電力受電部４への送電を効率良く行うことができる。   In addition, since the second circuit module group and the antenna unit 1 are impedance matched, power transmission from the antenna unit 1 to the power receiving unit 4 can be performed efficiently.

（実施形態２）
図２は、本発明における実施形態１に係る非接触充電装置のブロック回路図である。 (Embodiment 2)
FIG. 2 is a block circuit diagram of the contactless charging apparatus according to Embodiment 1 of the present invention.

実施形態１における図１とは、直列コンデンサと共通回路部２２の間に整合切替スイッチ部２１を設けている点が異なる。   FIG. 1 in the first embodiment is different from FIG. 1 in that a matching changeover switch unit 21 is provided between the series capacitor and the common circuit unit 22.

また、負荷変調通信部３１、送信部３２、受信部３３と整合回路部２との間に保護半導体スイッチ９を設けている点が異なる。   Further, the difference is that the protective semiconductor switch 9 is provided between the load modulation communication unit 31, the transmission unit 32, the reception unit 33 and the matching circuit unit 2.

アンテナ部１を介して外部と通信する場合は保護半導体スイッチ９を導通状態とし、アンテナ部１が電力を受電する場合は、保護半導体スイッチ９を遮断状態とする。   When communicating with the outside via the antenna unit 1, the protective semiconductor switch 9 is turned on, and when the antenna unit 1 receives power, the protective semiconductor switch 9 is turned off.

これにより、負荷変調通信部３１、送信部３２、受信部３３の電力信号からの万全な保護を図ることができる。   Thereby, thorough protection from the power signals of the load modulation communication unit 31, the transmission unit 32, and the reception unit 33 can be achieved.

電力受電部４とインピーダンス整合条件が共通する負荷変調通信部３１には電力信号による過剰な電圧が発生する恐れがあるため、保護半導体スイッチ９を設けることが特に望ましく、電力受電部４とインピーダンス整合条件が相違する送信部３２、受信部３３の保護半導体スイッチ９を設けなくともよい。   The load modulation communication unit 31 having the same impedance matching condition as that of the power receiving unit 4 may generate an excessive voltage due to the power signal. Therefore, it is particularly desirable to provide the protective semiconductor switch 9 and impedance matching with the power receiving unit 4. It is not necessary to provide the protection semiconductor switch 9 of the transmission unit 32 and the reception unit 33 having different conditions.

また、本実施形態では、外部から受電を行う非接触充電装置としたが、電力受電部４を交流電源に置き換え、非接触送電装置としてもよい。   Moreover, in this embodiment, although it was set as the non-contact charging device which receives electric power from the outside, it is good also as a non-contact power transmission device by replacing the electric power receiving part 4 with an alternating current power supply.

また、整合切替スイッチ部２１の配置は、本実施形態のものに限らず、整合回路部２の任意の部分にしてもよい。   Further, the arrangement of the matching changeover switch unit 21 is not limited to that of the present embodiment, and may be an arbitrary part of the matching circuit unit 2.

さらに、整合切替スイッチ部２１を半導体とコンデンサの直列構成とするだけでなく、インダクタや抵抗等の任意の受動部品と半導体スイッチを組み合わせて構成してもよい。   Furthermore, the matching changeover switch unit 21 is not limited to a series configuration of a semiconductor and a capacitor, but may be configured by combining an arbitrary passive component such as an inductor or a resistor with a semiconductor switch.
