Abstract

<P>PROBLEM TO BE SOLVED: To provide a charge type radio tag capable of effectively using radio wave energy in both communication and non-communication. <P>SOLUTION: When a changeover switch 2 is switched to a data transmission state, electricity generated by an electricity generating part is supplied to a circuit for transmission, and used for a power for transmitting the data of a radio tag IC 3. On the other hand, when the changeover switch 2 is switched to a non-transmission state, a battery (electric double layer capacitor) 7 or the like is charged with electricity generated by an electricity generating part. Then, the electricity stored in the battery 7 is supplied to a circuit for transmission when the next data transmission is started. Thus, it is possible to transmit the data of the radio tag IC3 with a large power, and to expand a communication validating area. Also, in non-transmission, this charging type radio tag is charged with radio wave energy so that the radio wave energy can be validly used. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本発明は、無線タグが送信状態にあるときは、無線タグ内で生成した生成電気を送信用に使用し、非送信状態にあるときは生成した余剰の電気を充電して蓄え、蓄えた電気を次回のデータ送信用として使用するようにした充電式の無線タグに関するものである。   When the wireless tag is in a transmission state, the generated electricity generated in the wireless tag is used for transmission, and when it is in a non-transmission state, the generated surplus electricity is charged and stored, and the stored electricity is stored. The present invention relates to a rechargeable wireless tag that is used for the next data transmission.

最近では、ＲＦ−ＩＤリーダ／ライタ（以下は、単にリーダ側という）からの無線電波を受信して内部で動作用の電源を確保し、メモリに記憶されているデータを送信するようにした非接触型の無線タグ（ＩＣタグともいう）が広く普及してきている。このような非接触型の無線タグは高機能であるため、その消費電力は大きく、これを無線電波のみから得る場合には、データを送信するための電力が十分でなくなり、通信可能エリアが狭まるという欠点があった。そのため、従来においては、特許文献１及び２に示すように、無線タグ内に電気を蓄えておく蓄電池を備えるようにしたものが公知である。   Recently, a wireless radio wave from an RF-ID reader / writer (hereinafter simply referred to as a reader side) is received to secure a power supply for operation inside, and data stored in a memory is transmitted. Contact-type wireless tags (also referred to as IC tags) have become widespread. Since such a non-contact type wireless tag has a high function, its power consumption is large, and when it is obtained only from a radio wave, power for transmitting data is not sufficient, and a communicable area is narrowed. There was a drawback. For this reason, conventionally, as shown in Patent Documents 1 and 2, a battery having a storage battery for storing electricity in a wireless tag is known.

特許文献１に記載されたＩＣカードは、アンテナで受信した電波エネルギーを用いて受信部で電気を生成させ、かつ、該受信部と電気的に接続する返信信号強化電源手段で蓄積された余剰電力に基づき、データ制御回路と電気的に接続する送信部の返信信号を強化させるようにしている。   The IC card described in Patent Document 1 uses surplus power stored in a reply signal-enhanced power supply unit that generates electricity at a receiving unit using radio wave energy received by an antenna and is electrically connected to the receiving unit. Based on the above, the reply signal of the transmitter electrically connected to the data control circuit is strengthened.

特許文献２に記載されたＩＣカードシステムは、リーダ側の識別装置に送信用の電源を供給するためのアンテナコイル部と、充電用の電源を供給するためのアンテナコイル部とを設けている。そして、ＩＣカード側には、同様に送信用の電源を確保するためのアンテナコイル部と、充電用の電源を確保するためのアンテナコイル部とを設け、充電式の電池とを設けている。これにより、通信時に送信用の電源と、充電用の電源とを確保し、充電池の電気消耗を低減するようにしている。
特開平９−２９３１２８号公報 特開平１０−３０７８９８号公報 The IC card system described in Patent Document 2 includes an antenna coil unit for supplying power for transmission to the reader-side identification device and an antenna coil unit for supplying power for charging. On the IC card side, similarly, an antenna coil part for securing a power source for transmission and an antenna coil part for securing a power source for charging are provided, and a rechargeable battery is provided. As a result, a power supply for transmission and a power supply for charging are secured during communication, and the electric consumption of the rechargeable battery is reduced.

ところが、前記特許文献１に記載された技術にあっては、情報交信装置からの複数個の命令信号に基づいて、主機能をＯＮ，ＯＦＦしたり、充電をＯＮ，ＯＦＦしたりしており、情報交信装置から複数の命令信号を送信する必要があった。また無線タグ側の状態を識別する機能は備えていなかった。一方、特許文献２に記載された技術も、無線タグ（ＩＣカード）側の状態を識別する機能は備えていなかった。   However, in the technique described in Patent Document 1, based on a plurality of command signals from the information communication device, the main function is turned on and off, and charging is turned on and off. It was necessary to send a plurality of command signals from the information communication device. Moreover, the function which identifies the state by the side of a wireless tag was not provided. On the other hand, the technique described in Patent Document 2 does not have a function for identifying the state on the wireless tag (IC card) side.

本発明は従来の前記課題に鑑みてこれを改良除去したものであって、データ送信状態のときには送信用の電源を確保し、非送信状態のときには充電用の電源を確保するようにし、電波エネルギーをデータ送信時及び非送信時のいずれにおいても有効利用できるようにしつつ、無線タグに設けたスイッチをＯＮするとデータが送信されることにより、無線タグ側の状態を識別する機能をも備えた充電式の無線タグを提供せんとするものである。   The present invention has been improved and removed in view of the above-described conventional problems. In the data transmission state, a power source for transmission is secured, and in a non-transmission state, a power source for charging is secured. Charging with the function of identifying the state of the wireless tag by transmitting data when the switch provided on the wireless tag is turned ON, while making it possible to effectively use both the data transmission and non-transmission We intend to provide a wireless tag of the type.

前記課題を解決するために本発明が採用した請求項１の手段は、リーダからの無線電波を受信するアンテナと、無線電波を受信して電源の供給を受け、この電源を利用してデータをアンテナからリーダへ送信する無線タグＩＣと、当該無線タグＩＣのデータの送信をＯＮ／ＯＦＦ切替する切り替えスイッチとを備えた無線タグであって、切り替えスイッチがＯＦＦ状態のときにリーダからの無線電波をアンテナで受信して得られた生成電力を充電する充電部と、切り替えスイッチがＯＮ状態に切り替わったときに、前記充電部で充電された電力を、送信回路へ供給する制御回路とを備えていることを特徴とする充電式の無線タグである。   The means of claim 1 adopted by the present invention to solve the above-mentioned problem is that an antenna for receiving radio waves from a reader and a radio wave are received and supplied with power, and data is obtained using this power source. A wireless tag including a wireless tag IC that transmits from an antenna to a reader and a changeover switch that switches ON / OFF transmission of data of the wireless tag IC, and a wireless radio wave from the reader when the changeover switch is OFF And a control circuit that supplies the power charged in the charging unit to the transmission circuit when the changeover switch is switched to the ON state. It is a rechargeable wireless tag characterized by being.

このように請求項１の発明にあっては、切替スイッチが送信状態（ＯＮ状態）と、充電状態（ＯＦＦ状態）とを切り替えるようになっている。送信状態（ＯＮ状態）に切り替えられた時は、電気生成部で生成された電気は送信用回路に供給されて無線タグＩＣのデータを送信するための電力に使用されるようになっている。一方、充電状態（ＯＦＦ状態）に切り替えられた時は、電気生成部で生成された電気を充電用回路で充電池等に充電するようにしている。そして、充電池へ蓄えられた電気は、次回のデータ送信開始時に送信用回路へ供給される。そのため、大きな電力で送信することができるようになり、通信可能エリアの拡大が図れる。また非送信時の電波エネルギーを充電しており、電波エネルギーの有効活用が可能である。なおかつ、切替スイッチがＯＮとなったときに、データが送信されるので、無線タグ側の状態を識別することが可能である。   Thus, in the invention of claim 1, the changeover switch switches between the transmission state (ON state) and the charging state (OFF state). When switched to the transmission state (ON state), the electricity generated by the electricity generation unit is supplied to the transmission circuit and used for power for transmitting data of the RFID tag IC. On the other hand, when the charging state (OFF state) is switched, the electricity generated by the electricity generating unit is charged into a rechargeable battery or the like by the charging circuit. The electricity stored in the rechargeable battery is supplied to the transmission circuit when the next data transmission starts. As a result, transmission can be performed with a large amount of power, and the communicable area can be expanded. Moreover, the radio wave energy at the time of non-transmission is charged, and the radio wave energy can be effectively used. In addition, since the data is transmitted when the changeover switch is turned on, the state on the wireless tag side can be identified.

以下に、本発明の構成を図面に示す発明の実施の形態に基づいて説明すると次の通りである。図１は本発明の第１の実施の形態に係る充電式無線タグ１の全体を示すシステム構成図である。同図に示す如く、この実施の形態の無線タグ１は、送信状態（ＯＮ状態）と充電状態（ＯＦＦ状態）に切り替える切替スイッチ２と、無線タグＩＣ３と、アンテナ４とを有している。切替スイッチ２は、接片５が接点Ｓ１へ切り替えられたときに、電気生成部（図示せず）で生成した電気を動作用電源として用い、無線タグＩＣ３内に記憶されているデータをアンテナ４を通じて無線通信インターフエイスで送信するようになっている。このとき形成される回路が送信用回路である。また切替スイッチ２は、接片５が接点Ｓ２へ切り替えられたときは、電気生成部で生成した電気を電気二重層コンデンサ６へ供給して充電するようになっている。このとき形成される回路が充電用回路である。切替スイッチ２は、例えば、公知の押しボタン式とし、人が押しボタンを押すと、接片５が接点Ｓ１側へ切り替えられる構成とすることができる。   The configuration of the present invention will be described below based on the embodiment of the invention shown in the drawings. FIG. 1 is a system configuration diagram showing the entire rechargeable wireless tag 1 according to the first embodiment of the present invention. As shown in the figure, the wireless tag 1 of this embodiment includes a changeover switch 2 that switches between a transmission state (ON state) and a charging state (OFF state), a wireless tag IC 3, and an antenna 4. When the contact piece 5 is switched to the contact S1, the changeover switch 2 uses the electricity generated by the electricity generation unit (not shown) as an operation power source, and uses the data stored in the wireless tag IC 3 as the antenna 4 Through the wireless communication interface. The circuit formed at this time is a transmission circuit. Further, when the contact piece 5 is switched to the contact S2, the changeover switch 2 supplies the electricity generated by the electricity generation unit to the electric double layer capacitor 6 for charging. The circuit formed at this time is a charging circuit. The changeover switch 2 may be, for example, a known push button type, and the contact piece 5 can be switched to the contact S1 side when a person presses the push button.

一方、無線タグ１はＲＦ−ＩＤリーダ／ライタ（リーダユニット）（以下は、リーダ側という）８のアンテナ９を通じて通信を行い、充電用回路に蓄えられた充電電力を、スイッチがＯＮに切り替えられたとき（データ送信）に、送信用回路３へ供給する制御回路７を有している。リーダ側８からは無線タグ１へ送信用及び充電用の電源を供給するための電波エネルギーが絶えず出力されている。   On the other hand, the wireless tag 1 communicates through an antenna 9 of an RF-ID reader / writer (reader unit) (hereinafter referred to as a reader side) 8 so that the charging power stored in the charging circuit can be turned on. A control circuit 7 that supplies the data to the transmission circuit 3 when the data is transmitted (data transmission). From the reader side 8, radio wave energy for supplying power for transmission and charging to the wireless tag 1 is continuously output.

このように構成された無線タグ１のシステムにおいて、充電状態（ＯＦＦ状態）のときは切替スイッチ２の接片５は接点Ｓ２側へ切り替えられている。そのため、リーダアンテナ９から出力される電波エネルギーはタグアンテナ４で受信され、電気生成部において充電用の電気が生成される。生成された電気は、電気二重層コンデンサ６へ充電される。   In the wireless tag 1 system configured as described above, the contact piece 5 of the changeover switch 2 is switched to the contact S2 side in the charged state (OFF state). Therefore, the radio wave energy output from the reader antenna 9 is received by the tag antenna 4, and electricity for charging is generated in the electricity generation unit. The generated electricity is charged into the electric double layer capacitor 6.

そして、例えば、人が図示しない押しボタンを押したときに、切替スイッチ２の接片５は接点Ｓ１側へ切り替えられる。このとき、リーダアンテナ９から出力される電波エネルギーは、タグアンテナ４で受信され、電気生成部において生成された電気は、無線タグＩＣ３の動作用の電源となる。これにより、無線タグＩＣ３のメモリに記憶されていたデータが、アンテナ４から無線インターフエイス（リーダアンテナ９）を通じてリーダ側８へ送信されるようになる。   For example, when a person presses a push button (not shown), the contact piece 5 of the changeover switch 2 is switched to the contact S1 side. At this time, the radio wave energy output from the reader antenna 9 is received by the tag antenna 4, and the electricity generated in the electricity generator serves as a power source for operation of the wireless tag IC 3. As a result, the data stored in the memory of the wireless tag IC 3 is transmitted from the antenna 4 to the reader side 8 through the wireless interface (reader antenna 9).

またこのとき、制御回路７の働きによって、充電用回路の電気二重層コンデンサ６に蓄えられていた電荷が放電され、送信は電気生成部で生成された電力にプラスして電気二重層コンデンサ６の電力が加わり、大きな電力をもって送信される。そのため、通信可能エリアの拡大を実現でき、また安定且つ確実な送信が可能となる。リーダ側８では、前記送信されてきたデータによって目的とする機器が所定の動作を行うようになる。   At this time, the electric charge stored in the electric double layer capacitor 6 of the charging circuit is discharged by the action of the control circuit 7, and transmission is added to the electric power generated by the electric generator and the electric double layer capacitor 6 Power is added and transmitted with large power. Therefore, it is possible to expand the communicable area and to perform stable and reliable transmission. On the reader side 8, a target device performs a predetermined operation based on the transmitted data.

このように、この第１の実施の形態の無線タグ１では、人が押しボタンを押す等の無線タグ側の状態を識別することができ、なおかつ、リーダ側８から供給される電波エネルギーを、データ送信状態のときも、非送信状態のときも有効利用するようにしており、無駄がない。   As described above, in the wireless tag 1 of the first embodiment, it is possible to identify the state on the wireless tag side such as a person pressing a push button, and the radio wave energy supplied from the reader side 8 is Effective use is made in both the data transmission state and the non-transmission state, and there is no waste.

図２は本発明の第２の実施の形態にかかる充電式無線タグ１０の全体のシステム構成図である。この第２の実施の形態では、前記第１の実施の形態の制御回路７に時計表示やその他の機能を有する機器１０を接続している。切替スイッチ５が接点Ｓ２側へ切り替えられた非送信時（スイッチＯＦＦ時）に、充電用回路が形成され、リーダ側から供給される無線電波エネルギーをタグアンテナ４が受信して電気生成部で電気を生成する。そして、生成された電気は、電気二重層コンデンサ６へ充電され、また制御回路７を通じて機器１１へ供給され、時計表示等が行われる。切替スイッチ２の接片５が接点Ｓ１側へ切り替えられたデータ送信時（スイッチＯＮ時）に、電気生成部で生成された電気と、電気二重層コンデンサ６に蓄積された電荷とがプラスされ、無線タグＩＣ３の送信用電源として大きな電力が得られることは前記第１の実施の形態の場合と同じである。またその他の構成並びに作用効果も同一である。   FIG. 2 is an overall system configuration diagram of the rechargeable wireless tag 10 according to the second embodiment of the present invention. In the second embodiment, a device 10 having a clock display and other functions is connected to the control circuit 7 of the first embodiment. At the time of non-transmission (switch OFF) when the changeover switch 5 is switched to the contact S2 side, a charging circuit is formed, and the tag antenna 4 receives the radio wave energy supplied from the reader side, Is generated. The generated electricity is charged into the electric double layer capacitor 6 and supplied to the device 11 through the control circuit 7 to display a clock. At the time of data transmission (switch ON) when the contact piece 5 of the changeover switch 2 is switched to the contact S1 side, the electricity generated by the electricity generation unit and the charge accumulated in the electric double layer capacitor 6 are added, As in the case of the first embodiment, a large amount of power can be obtained as a transmission power source for the wireless tag IC3. Other configurations and operational effects are also the same.

ところで、本発明は上述した実施の形態に限定されるものではなく、適宜の変更が可能である。例えば、本発明が対象とする装置や機器は、無線タグを利用するものであればあらゆるものが含まれる。また図２に示す制御回路７に接続された機器も、時計以外のあらゆるものに適用することが可能である。   By the way, this invention is not limited to embodiment mentioned above, A suitable change is possible. For example, any device or device targeted by the present invention includes any device that uses a wireless tag. Also, the device connected to the control circuit 7 shown in FIG. 2 can be applied to anything other than a watch.
