Description

本発明は、共振タグ、非接触ICタグを用いた外的要因変化感知検出システムに関する。 The present invention, resonant tags, to external factors change sensitive detection system using a non-contact IC tag.

情報の機密性の面からICカードが次第に普及されつつある中、近年では、読み書き装置(リーダライタ)と接触せずに情報の授受を行う非接触型のICカードが提案され、中でも、外部の読み書き装置との信号交換を、あるいは信号交換と電力供給とを電磁波により行う方式のものが実用化されつつある。 While IC card confidentiality surface information is being increasingly popular in recent years, non-contact type IC card for exchanging information without contacting the reading and writing apparatus (reader-writer) is proposed, inter alia, an external a signal exchange with the reading and writing apparatus, or those of the signal exchange and system by electromagnetic waves and a power supply is being put to practical use.
そして、データを搭載したICを、アンテナコイルと接続した、シート状ないし札状の非接触式のICタグが、近年、種々提案され、商品や包装箱等に付け、万引き防止、物流システム、商品管理等に利用されるようになってきた。 Then, the IC mounting the data and connected to the antenna coil, IC tag of the non-contact type of the sheet-like or Satsujo has recently been proposed, with the product or its packaging, etc., shoplifting, distribution system, product It has come to be used in the management and the like.
勿論、ICを持たない単なる共振タグも物品の存在感知に用いられている。 Of course, mere resonant tag having no IC is also used in the presence sensing article.

上記ICを持たない単なる共振タグやICタグは、いずれも、物品の存在感知や、物品の識別を行うもので、外的要因の変化をとらえるものではない。 Mere resonant tag or IC tag which does not have the IC are both present sensing and articles, and performs identification of the article, it does not capture the variation of external factors.
個別に設定した共振周波数を持つ共振タグの場合も、物品の存在感知や、物品の識別を行うもので、外的要因の変化をとらえるものではない。 In the case of resonant tag having a resonance frequency set individually, there sense and articles, and performs identification of the article, it does not capture the variation of external factors.
物品の外的要因である温度の変化を把握するために、たとえば、温度センサとCPU、メモリと電池を内蔵したボタン型の温度モニタデバイスの使用も考えられるが、センサ、CPU、メモリ、電池を内蔵するため1ケ数千円と高価で、内蔵電池で動くため寿命が短い。 To understand the changes in temperature which is external factor of the article, for example, a temperature sensor a CPU, using a temperature monitoring device of the button type with a built-in memory and battery are also contemplated, but sensor, CPU, memory, a battery expensive and 1 pc several thousand yen to built, short lifetime for movement in the built-in battery.

このように、従来、タグは、物品の存在感知や物品の識別を行うために専ら用いられ、物品の温度等環境の変化を把握するためには、温度モニタデバイスのように高価であったり、あるいは、サーモラベルのように扱いに手間がかかるため、物品の環境変化を把握するためには用いられていなかった。 Thus, conventionally, the tag is used exclusively for identification of presence sensing and articles of the article, in order to grasp the change in temperature or the like environment of the article, or a costly as the temperature monitoring device, Alternatively, since it takes time to handle as thermo label, in order to determine the environmental change of the article it has not been used.
尚、共振タグの周波数識別方法としては、従来から、特開2000- 49655号公報にも記載のように、ディップメーター方式とエコー波感知方式等が知られている。 As the frequency identification method of the resonant tag, conventionally, as described in JP-A-2000- 49655, dip meter method and echo wave sensing method, etc. are known.

(作用) (Action)
本発明の外的要因変化感知検出システムは、このような構成にすることにより、タグを用いて、簡便に物品の環境変化を把握できる方法を実施できる外的要因変化感知検出システムの提供を可能とした。 External factors change sensitive detection system of the present invention, by adopting such a configuration, by using a tag, conveniently possible to provide external factors change sensitive detection system capable of implementing the method that can determine the environmental change of the article and the.
詳しくは、外的要因の変化により共振周波数が変化するように設定された共振回路を有するタグと、前記タグの変化した共振周波数を含む所定の周波数区間でタグを感知する検出器とを備えている場合は、少なくとも外的環境が変化したタグを検出することができ、これより、そのタグが添付されている物品が外的環境の変化を受けていることを判断できるものとしている。 For more information, includes a tag having a set resonant circuit so that the resonance frequency changes due to changes in external factors, and a detector for sensing the tag at the predetermined frequency interval including the changed resonant frequency of the tag when on, it is possible to detect the tags at least external environment changes, than this, it is assumed that it can be determined that the article the tag is attached is in response to the change of external environment.
また、外的要因の変化により共振周波数が変化するように設定された共振回路と該共振回路に接続されたICチップを有する非接触ICタグと、前記ICタグの変化した共振周波数を含む所定の周波数区間でICタグを検知し、且つ、ICチップの情報の読み出しを行いICタグを個別識別する、検出読み出し機とを備えている場合は、外的環境が変化したタグを検出することができ、更に、そのタグのICチップの保持する情報を把握でき、これにより、そのタグが添付されている物品が外的環境の変化を受けていると判断でき、且つ、そのタグが添付されている物品の個別情報を把握することができるものとしている。 Also, a non-contact IC tag having an IC chip connected to the set resonant circuit and the resonant circuit so that the resonance frequency due to changes in external factors are changed, a predetermined including altered resonance frequency of the IC tag detecting the IC tag at the frequency interval, and, individually identifying the IC tag reads the information of the IC chip, if a detection reading apparatus can detect a tag external environment changes further, can grasp information held by the IC chip of the tag, thereby, it can be determined that the article the tag is attached is in response to the change of external environment, and, the tag is attached it is assumed that it is possible to grasp the individual information of the article.
したがって、タグが添付されている物品が、外的環境の変化を受けているか否かを判別でき、あるいは、グが添付されている物品が、外的環境の変化を受けているか否かを判別できるとともに、その物品の個別情報を把握でき、外的環境の変化を受けた物品と受けなかった物品とを識別、区分けをすることを可能としている。 Therefore, the article the tag is attached is, to determine whether the response to the change of external environment, or discrimination article grayed is attached, whether in response to the change of external environment it is possible, the individual information of the article can grasp the identification received and articles that did not receive the article changes in the external environment, it is made possible to the division.
外的要因の変化として、温度の他、湿度、水分、圧力、気体濃度、加速度、衝撃等のタグの環境変化を挙げられる。 As a change in external factors, other temperatures, and humidity, moisture, pressure, gas concentration, acceleration, the environmental change in the tag such as an impact.
具体的には、タグの環境変化により共振回路の容量成分を変化させ、共振周波数を変化させるものが挙げられる。 Specifically, the environmental change of the tag by changing the capacitive component of the resonant circuit, include one that changes the resonant frequency.

本発明の外的要因変化感知検知システムにおいては、外的要因の変化に対する共振周波数の変化が可逆的であると、タグの近くに、タグの変化した共振周波数を含む所定の周波数区間で、タグを感知する検出器をあるいは検出読み出し機を配している場合には、所定の外的要因の変化を連続あるいは、周期的、断続的に感知することができ、所望の外的要因の変化を感知し、感知した時点で判別、区分け、認識等ができる。 In external factors change sensing detection system of the present invention, the change in the resonant frequency to changes in external factors is reversible, near the tag, at a predetermined frequency interval including the changed resonant frequency of the tag, the tag If it is arranged detector or detection reading device that senses a continuous change of a predetermined external factor or periodically, intermittently can sense the change of the desired external factors sensed, determined at the time of the sensing, segmentation can recognize the like.
あるいは、ICタグの場合には、所望の外的要因の変化をその変化時にメモリに記憶して、その後に、記憶したデータを判別、区分けを行うこともできる。 Alternatively, if the IC tag is stored in the memory the change in the desired external factor at the time of the change, then, the stored data determination can also be performed division.
しかし、タグの近くに検出器あるいは検出読み出し機がなく、タグをつけ物品を検出器あるいは検出読み出し機まで移動して、外的要因の変化を受けたか否かを調べる場合には、物品が外的要因の変化を受けたか否かを正確に知ることはできない。 However, there is no detector or detection reading unit near the tag, by moving the tagged article to a detector or detection reading machine, when examining whether it has received a change in external factors, the external article We can not know exactly whether or not to have received the change of factors.

これに対して、タグの近くに検出器あるいは検出読み出し機がなく、タグをつけ物品を検出器あるいは検出読み出し機まで移動して、外的要因の変化を受けたか否かを調べる場合には、外的要因変化が履歴に残るように、外的要因変化の変化に対して周波数が不可逆的な変化を示す不可逆素子を使用したタグを用いる。 On the contrary, if no detector or detection reading unit near the tag, by moving the tagged article to a detector or detection reading machine checks whether it has received a change of external factors, as external factors change remains in the history, the frequency with respect to changes in external factors change using tags using a lossy element exhibiting irreversible changes.
たとえば、コンデンサの誘電体の組成を工夫することにより、温度に対応して誘電体自体を変化させることにより、その容量変化を温度に対し不可逆的にすることができる。 For example, by devising the composition of the dielectric of the capacitor, by changing the dielectric itself in response to temperature, it can be irreversible with temperature the capacitance change.
具体的な例としては、セラミックコンデンサを、温度変化により共振回路の容量成分を変化させる素子として挙げられるが、これは、セラミックコンデンサの容量変化が不可逆的な温度履歴を示す範囲を利用するものである。 As a specific example, a ceramic capacitor, but may be mentioned as an element for changing the capacitive component of the resonance circuit due to temperature changes, this is the capacitance change of the ceramic capacitors utilize a range indicating the irreversible temperature history is there.
また、回路の開放、短絡を利用して共振周波数の変化を誘発させるためには、温度ヒューズにような不可逆的な素子を用いることができる。 Further, opening of the circuit, in order to induce a change in the resonance frequency by utilizing the short-circuit, it is possible to use irreversible element such as a temperature fuse.

本発明に用いられるタグは、前述のような構成にすることにより、タグを用いて、上記本発明の、簡便に物品の環境変化を把握できる外的要因変化感知検出システムの提供を可能とした。 Tags used in the present invention, by a as described above arrangement, by using the tag, and allows the present invention, the easily provide external factors change sensitive detection system which can determine the environmental change of the article .

先ず、本発明の外的要因変化感知検出システムに用いられるタグの第1の例を図1に基づいて説明する。 First, a first example of a tag for use in external factors change sensitive detection system of the present invention will be described with reference to FIG.
第1の例は、図1(a)に示すように、アンテナコイル130に、その容量成分が、使用温度範囲で可逆的に温度依存性を示す外的要因変化により容量の変化する素子(セラミックコンデンサ等)120を直列に接続した、図1(b)に示す回路の共振タグである。 The first embodiment, as shown in FIG. 1 (a), the antenna coil 130, the capacitance component, element which changes in capacity due to an external factor changes indicative of reversible temperature dependent at the operating temperature range (ceramic capacitors, etc.) 120 connected in series, the resonant tag of the circuit shown in FIG. 1 (b). アンテナコイル130、外的要因変化により容量の変化する素子120は絶縁性フィルム150の一面に配され、端子部131とアンテナコイルの外側とは、接続配線部140で接続されている。 The antenna coil 130, element 120 which varies in capacitance due to an external factor changes disposed on one surface of the insulating film 150, and the outer terminal portion 131 and an antenna coil, are connected by connection wiring portion 140.
また、外的要因変化により容量の変化する素子120は端子部131と端子部132間に配されている。 Furthermore, element 120 which varies in capacitance due to an external factor changes are disposed between the terminal portion 131 and the terminal portion 132.
温度の変化により、外的要因変化により容量の変化する素子120はその容量成分を変化させるため、図1(b)に示す回路で、容量成分のみが温度の変化にともない可逆的に変化し、その共振周波数が変化する。 By a change in temperature, element 120 which varies in capacitance due to an external factor changes to vary the capacitance component, the circuit shown in FIG. 1 (b), only the capacitance component is changed reversibly with the change in temperature, the resonance frequency changes.
例えば、図4に示すように、タグの周波数特性は、温度T1のf1に共振周波数を持つ周波数特性から、温度T2のf2に共振周波数を持つ周波数特性へと変化する。 For example, as shown in FIG. 4, the frequency characteristic of the tag is changed from the frequency characteristic with a resonant frequency f1 of the temperature T1, to a frequency characteristic with a resonant frequency f2 of the temperature T2.
図4において、410は温度T1における周波数特性で、420は温度T2における周波数特性である。 4, 410 in the frequency characteristic at the temperature T1, 420 is a frequency characteristic at the temperature T2.
この場合、充分に短かい周期で周波数f1にてタグを感知するためのリーダと、充分に短かい周期で周波数f2にてタグを感知するためのリーダとによりタグの読み出しを行うことにより、それぞれ、タグの温度がT1、T2にあるか否かを知ることができる。 In this case, intimately with a reader for sensing the tag at frequency f1 at shorter period, sufficiently by reading out the tag by a reader for sensing tags in shorter periods at a frequency f2, respectively , the temperature of the tags can be known whether the T1, T2.
したがって、仮に、一方の温度T1を基準の温度状態のタグの温度とし、他方の温度T2を所定の異常時のタグの温度とすれば、充分に短かい周期で周波数f2にてタグを感知することによりタグの異常温度状態の有無を判別することができ、これより、このようなタグをつけた物品の温度変化の有無も判別することができる。 Accordingly, if, one of the temperature T1 and the temperature of the tag temperature state of the reference, if the other temperature T2 and the temperature of the tag when a predetermined abnormality sensing the tag at frequency f2 sufficiently in shorter periods can determine the presence or absence of abnormal temperature state of the tag by, than this, the presence or absence of change in temperature of the article wearing such tags can also be determined.
このように、第1の例のタグは、タグの異常温度状態の有無、温度変化の有無を共振周波数の変化としてとらえることができるものである。 Thus, the tag of the first example is capable of capturing the presence or absence of the abnormal temperature state of the tag, the presence or absence of a change in temperature as a change in resonance frequency.
尚、通常は基準の温度状態では、ISO/IEC15693規格の近傍型に準じて、共振周波数を13.56MHzとしておく。 Incidentally, usually in a temperature state of the reference, in accordance with the proximity type ISO / IEC15693 standard, leaving the resonant frequency 13.56 MHz.

接続配線部140としては、アンテナコイル130上で絶縁材を介して、導電性層を形成して、あるいはワイヤによりアンテナコイル130の外側と端子部131とを電気的に接続したものや、絶縁性基材150のアンテナコイル形成面側でない面に接続用配線部を設け、これとアンテナコイル130の外側とを、および端子部131とをかしめ接続したもの(図2(a)のかしめ接続部240、241、接続配線部245の接続を参照)が挙げられる。 The connection wiring portion 140, through the insulating material on the antenna coil 130, to form a conductive layer or and that electrically connects the outer terminal portion 131 of the antenna coil 130 by a wire, insulating the connection wiring portion is provided on a surface not an antenna coil forming surface of the substrate 150, this and an outer antenna coil 130, and those caulking connects the terminal portion 131 (caulking connection portion of FIG. 2 (a) 240 , 241, refers to the connection of the connection wiring portion 245) can be mentioned.
絶縁性基材150としては、PET(ポリエチレンテレフタレート)、ポリプロピレン(PP)、ポリエチレン、ABS、スチレン、ポリイミド、ガラスエポキシ、PETG、ポリカーボネート、紙、PVC、またはアクリル等が挙げられるが、強度、耐熱、耐薬品性のあるPET(ポリエチレンテレフタレート)ないしポリイミドが好ましい。 As the insulating base material 0.99, PET (polyethylene terephthalate), polypropylene (PP), polyethylene, ABS, styrene, polyimide, glass epoxy, PETG, polycarbonate, paper, PVC, or acryl, and the like, strength, heat, chemically resistant PET (polyethylene terephthalate) or polyimide are preferred.
絶縁性基材150の厚さは、通常、25μm〜200μmである。 The thickness of the insulating substrate 150 is usually 25Myuemu~200myuemu.
アンテナコイル130を形成する金属材としては、Cu、Al等があるが、アンテナ配線の微細化、狭ピッチ化には、Cuが好ましい。 The metal material forming the antenna coil 130, Cu, there are Al, etc., miniaturization of the antenna wire, the narrower pitch, Cu is preferable.
電気特性からCu、Alの厚さは、それぞれ、10〜50μm、15〜50μmが好ましい。 From the electrical characteristics Cu, the Al thickness, respectively, 10 to 50 [mu] m, 15 to 50 m is preferable.

(第1の例のタグの変形例) (Modification of the tag of the first example)
第1の例は、その容量が可逆的に温度依存性の外的要因変化により容量の変化する素子120を、外的要因としての温度の変化に依存してタグの共振周波数を変化させる素子として用いたものであるが、外的要因変化により容量の変化する素子としては、所定の温度変化の下で、温度変化に対し履歴を示して不可逆的な容量変化特性を示すものがある。 The first example is the element 120 whose capacitance changes in capacitance due to an external factor changes reversibly temperature-dependent, as an element for changing the resonant frequency of the tag depending on the change in temperature as external factors although those using, as the element which changes volume due to an external factor changes, under a predetermined temperature change, there is shown an irreversible capacity change characteristic indicates a history over temperature.
このような特性を示す外的要因変化により不可逆的に容量の変化する素子を用いたものを第1の例の変形例として挙げられる。 Include that using a device that changes irreversibly capacity by external factors changes indicative of such characteristics as a modification of the first embodiment.
この変形例の場合は、温度変化の有無を、所定の容量変化履歴の容量変化の有無として感知することができるため、タグの異常温度に対応する周波数にて、充分に短かく周期的に、タグを感知するためのリーダによりタグの読み出しを行う必要はなく、少なくとも所望の時に、タグの異常温度に対応する周波数にてタグ感知するためのリーダとによりタグの読み出しを行えばよい。 For this modification, the presence or absence of a temperature change, it is possible to sense as the presence or absence of change in capacitance of a predetermined capacitance change history, at the frequency corresponding to the abnormal temperature of the tag, sufficiently to short periodically, need not by a reader for sensing a tag to read tag, when at least a desired, by a reader for the tag sensing at a frequency corresponding to abnormal temperature of the tag may perform readout of the tag.
また、不可逆的に容量変化を起こす素子はコンデンサ単独である必要はなく、ヒューズ等を併用しても良い。 The device also causing irreversible change in capacitance need not be a capacitor individually or as a combination of fuses and the like.

次に、本発明の外的要因変化感知検出システムに用いられるタグの第2の例を図2に基づいて説明する。 Next, a second example of a tag for use in external factors change sensitive detection system of the present invention will be described with reference to FIG.
第2の例は、図2(a)に示すように、アンテナコイル230に、その容量成分が温度依存性を示す外的要因変化により容量の変化する素子(セラミックコンデンサ等)220とICチップ210とを並列にして、これらを直列に接続した、図2(b)に示す回路の非接触型のICタグである。 The second embodiment, as shown in FIG. 2 (a), the antenna coil 230, the element (such as a ceramic capacitor) 220 and the IC chip 210 in which the capacitive component varies in capacitance due to an external factor changes showing temperature dependence the door and in parallel, they are connected in series, a non-contact type IC tag of the circuit shown in FIG. 2 (b).
アンテナコイル230、外的要因変化により容量の変化する素子220、ICチップ210は絶縁性フィルム250の一面に配され、これらは、アンテナコイル240の外側と、かしめ接続部240、241にてかしめ接続されている。 The antenna coil 230, elements 220, IC chip 210 that a change in capacitance due to an external factor changes disposed on one surface of the insulating film 250, these are an outer antenna coil 240, crimping connection by caulking connection portion 240 and 241 It is.
尚、接続配線部245は、絶縁性フィルム250のアンテナコイル形成面側でない面に設けられており、これをかしめ接続部240、241にて、それぞれ、接続して、図2(b)に示す回路を形成している。 The connection wiring portion 245 is provided on a surface not an antenna coil forming surface of the insulating film 250, which by caulking connection portion 240 and 241, respectively, are connected, shown in FIG. 2 (b) to form a circuit.
第2の例の場合も、第1の例と同様、温度の変化により、外的要因変化により容量の変化する素子220はその容量成分を可逆的に変化させるため、図2(b)に示す回路で、容量成分のみが変化し、その共振周波数が変化する。 In the case of the second embodiment, like the first embodiment, since the change in temperature, element 220 which varies in capacitance due to an external factor changes reversibly changing its capacitance component, shown in FIG. 2 (b) in the circuit, only the capacitance component is changed, the resonance frequency changes.
温度変化前の基準温度状態での動作の共振周波数をf12、温度変化後の所望の温度(異常温度のこと)での共振周波数をf22とすれば、第1の例の場合と同様、タグの前記所望の温度変化の感知を、充分に短かい周期で周波数f22にてタグ感知するリーダによりタグの読み出しを行うことにより、共振周波数の変化としてとらえることができる。 The resonance frequency of operation at a reference temperature state before a temperature change f12, if the resonant frequency at the desired temperature after the temperature change (that abnormal temperature) f22, as in the first example, the tag the desired sensing of temperature change, by reading out the tag by a reader to a tag sensing sufficiently at a frequency f22 in shorter period can be regarded as a change in the resonant frequency.
このように、第2の例のタグも、タグの所定温度変化の有無を共振周波数の変化としてとらえることができるものである。 Thus, the tag of the second embodiment also, is capable of capturing the presence or absence of a predetermined temperature change of the tag as a change in resonance frequency.
尚、第2の例の場合も、通常、基準の温度状態では、ISO/IEC15693規格の近傍型に準じて、共振周波数を13.56MHzとしておく。 Also in the case of the second embodiment, typically, the temperature state of the reference, in accordance with the proximity type ISO / IEC15693 standard, leaving the resonant frequency 13.56 MHz.
また、ICチップ110は、通常、大きさ1.0mm×0.9mm角、厚さ約150μm程度のものが用いられ、それ以外の各部については、第1の例と同様のものが使用できる。 Moreover, IC chip 110, typically, size 1.0 mm × 0.9 mm square is used is of the order of a thickness of about 150 [mu] m, for each part of the otherwise similar to the first embodiment can be used.

第2の例のものは、ICチップ210を備えていることにより、温度変化の有無の他に、メモリからその物品情報をより詳しく知ることができる。 Those of the second embodiment, due to the provision of the IC chip 210, in addition to the presence of temperature changes, can be known in more detail the article information from the memory.
また、第2の例のタグは、ICチップ210を備えていることにより、温度変化の有無を、そのメモリに蓄積させることも可能である。 The tag of the second embodiment, due to the provision of the IC chip 210, the presence or absence of a change in temperature, it is possible to accumulate in the memory.

(第2の例のタグの変形例) (Modification of the tag of the second embodiment)
第2の例は、その容量が可逆的に温度依存性の外的要因変化により容量の変化する素子220を、外的要因としての温度の変化に依存してタグの共振周波数を変化させる素子として用いたものであるが、外的要因変化により容量の変化する素子として、所定の温度変化の下で、温度変化に対し履歴を示して不可逆的な容量変化特性を示すものを用いたタグを第2の例の変形例として挙げられる。 Second example, the element 220 whose capacitance changes in capacitance due to an external factor changes reversibly temperature-dependent, as an element for changing the resonant frequency of the tag depending on the change in temperature as external factors Although one using, as an element which changes volume due to an external factor changes, under a predetermined temperature change, the tag using a shows the irreversible capacity change characteristic indicates a history over temperature first It is mentioned as a modification of the second example.
この変形例の場合は、温度変化の有無を、所定の容量変化履歴の容量変化の有無として感知することができるため、タグの異常温度に対応する周波数f22にて、充分に短かい周期で、タグを感知するためのリーダによりタグの読み出しを行う必要はなく、少なくとも所望の時に、タグの異常温度に対応する周波数f22にてタグ感知するためのリーダとによりタグの読み出しを行えばよい。 For this modification, the presence or absence of a temperature change, it is possible to sense as the presence or absence of change in capacitance of a predetermined capacitance change history, at the frequency f22 corresponding to abnormal temperature of the tag, sufficiently in shorter periods, it is not necessary to perform the reading of the tag by a reader for sensing the tags, when at least a desired, may perform reading of the tag by a reader to a tag sensing at the frequency f22 corresponding to abnormal temperature of the tag.

上記、第1の例のタグ、第2の例のタグは、いずれも、タグの温度変化をその共振回路の共振周波数の変化として把握するものであるが、湿度、水分、圧力、気体濃度、加速度、衝撃等の環境変化により、回路の周波数特性を変化させ、これらの変化を共振回路の共振周波数の変化として把握してもよい。 Above, the tag of the first embodiment, the tag of the second embodiment are both but is intended to grasp the temperature change of the tag as a change in the resonant frequency of the resonant circuit, humidity, moisture, pressure, gas concentration, acceleration, the environmental changes such as impact, changing the frequency characteristics of the circuit, may be aware of these changes as a change in the resonant frequency of the resonant circuit.
実際には、これらの環境の変化を回路の容量成分の変化としてとらえ、これから、共振周波数の変化として把握するのが容易であろう。 In fact, seize these changes in environment as a change in the capacitive component of the circuit, from which it will be easy to grasp as a change in resonance frequency.
例えば、容量成分を形成するための誘電体素材に、温度変化に伴い誘電体素材自体を変化させるものを混入あるいは分散させる。 For example, the dielectric material for forming the capacity component, mixed or dispersing one that changes the dielectric material itself due to the temperature change.

次いで、本発明の外的要因変化感知検出システムの実施の形態の1例を、図3に基づいて、簡単に説明する。 Then, an example embodiment of external factors change sensitive detection system of the present invention, with reference to FIG. 3 will be briefly described.
本例は、図2に示す第2の例のICタグにおいて、外的要因変化により容量の変化する素子(セラミックコンデンサ等)220を、所定の温度範囲の下で、不可逆的な容量変化特性を示す外的要因変化により容量の変化する素子に代えた第2の例の変形例のICタグを使用したもので、個別に箱体等に入れ包装してICタグをつけた生鮮食物等の物品345を、冷凍庫である保管庫310に多数保管しておき、必要時に1個づつ取り出し使用する際、各ICタグの共振周波数の変化の有無を温度変化の有無としてとらえ、これにより、物品の所定の温度変化有無を判別し、所定の温度変化が無かったものを良品345A、所定の温度変化が有ったものを良品345Bとして、区分けするシステムである。 This embodiment provides an IC tag of the second embodiment shown in FIG. 2, the elements (such as a ceramic capacitor) 220 to changes in capacitance due to an external factor changes, under a predetermined temperature range, the irreversible capacity change characteristic external factors vary with those using the IC tag of a modification of the second embodiment was replaced with elements that change in capacitance, articles perishable foods or the like with the IC tag packaged placed in individual box for indicating 345, and retain large number depot 310 is a freezer, when using extraction one by one when needed, catches the presence or absence of a change in the resonant frequency of each IC tag as the presence or absence of temperature changes, thereby, a predetermined article the temperature change whether to determine the non-defective ones given temperature was unchanged 345A, as nondefective 345B those there is a predetermined temperature change, a system for dividing.

本システムの動作の1例を、以下簡単に説明する。 An example of the operation of the system will be briefly described below.
冷凍庫である保管庫310に物品345を保管しておき、使用する際に、搬送ベルト360に載せ、1個づつ取り出し、順にゲート322を通過させ、共振周波数の変化の有無を異常感知リーダ320にて確認する。 Save the article 345 to vault 310 is a freezer, when used, placed on the conveyor belt 360, is taken out one by one, successively passed through a gate 322, the abnormality sensing reader 320 the presence or absence of a change in the resonant frequency to verify Te.
異常感知リーダ320は、所定の温度変化があった場合の共振周波数である第1の周波数f32にて、通信ができるか否かで、できる場合を所定の温度変化があったとし、できなかった場合を所定の温度変化がなかったとするものである。 Abnormality sensing reader 320, at a first frequency f32 is the resonance frequency when there is a predetermined temperature change, and on whether communication is possible, and a case where it was a predetermined temperature change, could not be If the it is to that no predetermined temperature change.
異常感知リーダ320は、第1の周波数f32(図4のf2に相当)にて、通信を行う電波送受信用ヘッドであるゲート322と処理部321を備え、結果を表示するディスプレイを設けたものがここでは使用されている。 Abnormality sensing reader 320, at a first frequency f32 (corresponding to f2 in FIG. 4), the gate 322 is a radio transmitting and receiving head for communication includes a processing unit 321, those provided with a display for displaying the results here are being used.
異常感知リーダ320にて温度変化有りと判断された物品は、区分けされ、不良品345Bとして回収される。 It is determined that there the temperature change in the abnormality sensing reader 320 articles are divided and collected as a defective product 345B.
所定の温度変化無しと判断された良品345Aは、そのまま進み、さらに、ゲート332を通過することにより、正常物品管理リーダ330により、個別情報の確認、関連処理が行われる。 Non-defective 345A is determined that the predetermined temperature change without, Continue, further passes through the gate 332, the normal article management reader 330, confirmation of the individual information, related processing is performed.
正常物品管理リーダ330は、所定の温度変化が無かった場合の共振周波数である第2の周波数f31(図4のf1に相当)にて通信を行う電波送受信用ヘッドであるゲート332と処理部331を備え、ここでも確認、処理等の結果を表示するディスプレイを設けたものがここでも使用されている。 Normal article management reader 330, gate 332 and processor 331 is a radio transmitting and receiving head for communicating at a second frequency f31 is the resonant frequency when a given temperature there is no change (corresponding to f1 in FIG. 4) comprising a confirmation Again, those provided with a display for displaying the results of processing and the like have been used here.
このようにして、所定の温度変化を受けなかった良品345Aのみを判別し、区分けして管理することができる。 Thus, to determine the only non-defective 345A that did not receive a predetermined temperature change, it can be managed divided.

本例の変形例としては、本システムにおいて、タグとして、先に述べた第1の例で示した、外的要因の変化に対し履歴を示して不可逆的な容量変化特性を示す素子を使用したタグを用いた場合のシステムが挙げられる。 As a modification of this example, in this system, as a tag, shown in the first example described above, was used element exhibiting an irreversible capacity change characteristic indicates a history to changes in external factors in the case of using the tag system can be mentioned.
この変形例の場合は、タグはICチップを持たないため、各物品の所定の温度変化の有無の判別と、それにもとづく区分けはできるが、各物品の個別情報の把握や、これに基づく処理を行うことは、ごく単純な場合を除いてほとんどできない。 For this modification, the tag does not have an IC chip, a determination of the presence or absence of a predetermined temperature change of each article, but division may based on it, grasp and separate information for each article, a process based on this it is, can hardly except when very simple to do.

別の外的要因変化感知検出システムとしては、第1の例のタグや第2の例のタグを用い、通常使用温度とは異なる所定の異常温度におけるタグの共振周波数と同じ周波数で、所定の短い周期で、タグを感知するリーダによりタグの読み出しを行うことにより、共振周波数の変化の有無をとらえ、これにより、物品の判別、区分けを行う形態のシステムも挙げられる。 Another external factor changes sensitive detection system, using a tag of a first example of a tag or the second embodiment, at the same frequency as the resonant frequency of the tag at different predetermined abnormal temperature the normal use temperature, predetermined a short cycle, by performing read by a reader of the tag to sense the tag, capture the presence or absence of change in the resonance frequency, thereby, determination of the article, also include system configuration for performing division.
本発明の外的要因変化感知検出システムは、上記に限られるものではない。 External factors change sensitive detection system of the present invention is not limited to the above.
例えば、外的要因変化により容量の変化する素子を、単に外的要因としての温度の変化に依存してタグの共振周波数を変化させる素子として用いた場合、先にも述べた通り、所望の温度変化の感知、即ち、異常温度の感知を、充分に短かい周期で周波数にてタグを感知するリーダによりタグの読み出しを行うことにより、共振周波数の変化としてとらえることができるが、異常温度を2以上とし、各温度に対応するタグの共振周波数を、それぞれ持つ、複数の異常検知用のリーダを用いて、タグと通信し、温度異常の有無を感知検出しても良い。 For example, if the element that varies in capacitance due to an external factor changes, was used as the element for changing the resonant frequency of the tag simply depending on the change in temperature as external factors, as described earlier, a desired temperature sensing a change, i.e., the sensing of the abnormal temperature, by reading out the tag by a reader to sense tags at sufficiently frequencies shorter period, can be regarded as a change in the resonance frequency, the abnormal temperature 2 and above, the resonant frequency of the tag corresponding to each temperature, with each using a plurality of abnormality detection of the reader communicates with a tag, it may be sensitive detecting the presence or absence of abnormal temperature.
この場合は、より精確に温度変化を把握することができる。 In this case, it is possible to grasp more accurately temperature variation.
