Title (EN) SENSING SYSTEM
(FR) SYSTÈME DE DÉTECTION
(JA) センシングシステム
Abstract:
(EN) A sensing system (10) comprises an electronic tag (12) and a reader device (14) that exchanges information with the electronic tag (12). The reader device (14) comprises a transmission unit (62) that emits AC waves which include a high-frequency component and a low-frequency component. The electronic tag (12) does not include a power source, and comprises a reception unit (21) that acquires a power source voltage from the high-frequency component of the AC wave and acquires a clock signal from the low-frequency component of the AC wave, and a response unit (38) that maintains the maximum amplitude of the clock signal and emits information aligned with the clock signal as a response signal. The reader device (14) further comprises a processing unit (44) that decodes, on the basis of the clock signal, the response signal emitted from the electronic tag (12).
(FR) L'invention concerne un système (10) de détection comportant une étiquette électronique (12) et un dispositif lecteur (14) qui échange des informations avec l'étiquette électronique (12). Le dispositif lecteur (14) comporte une unité (62) d'émission qui émet des ondes de courant alternatif comprenant une composante à haute fréquence et une composante à basse fréquence. L'étiquette électronique (12) ne comprend pas de source d'alimentation, et comporte une unité (21) de réception qui acquiert une tension de source d'alimentation à partir de la composante à haute fréquence de l'onde de courant alternatif et acquiert un signal d'horloge à partir de la composante à basse fréquence de l'onde de courant alternatif, et une unité (38) de réponse qui maintient l'amplitude maximale du signal d'horloge et émet des informations alignées avec le signal d'horloge en tant que signal de réponse. Le dispositif lecteur (14) comporte en outre une unité (44) de traitement qui décode, sur la base du signal d'horloge, le signal de réponse émanant de l'étiquette électronique (12).
(JA) センシングシステム(10)は電子タグ(12)と、電子タグ(12)と情報の授受を行う読取装置(14)とを有する。読取装置(14)は高周波成分と低周波成分とを含む交流電波を発信する送信部(62)を有し、電子タグ(12)は電源を有さず、交流電波の高周波成分から電源電圧を得、低周波成分からクロック信号を得る受信部(21)と、クロック信号の最大振幅を維持し、かつクロック信号に合わせて情報を返信信号として発信する返信部(38)とを有する。読取装置(14)は、更に電子タグ(12)から発信された返信信号をクロック信号に基づいてデコードする処理部(44)を有する。
