Title (EN) VEHICULAR SYSTEM AND TAG COMMUNICATION METHOD
(FR) SYSTÈME DE VÉHICULE ET PROCÉDÉ DE COMMUNICATION D'ÉTIQUETTE
(JA) 車両用システム及びタグ通信方法
Abstract:
(EN) A vehicular system (1) for detecting magnetic makers (10) installed in a road and wirelessly communicating with wireless tags (15) attached to the magnetic markers (10), said vehicular system comprising: a measurement unit (2) for detecting the magnetic markers (10) by sensing magnetism; a tag reader (34) for executing a communication process with respect to the wireless tags (15); and a control unit (32) for setting a communication start time, which is the start of the communication process executed by the tag reader (34). The control unit (32) sets, as a communication start time, a point in time after the elapse of a prescribed amount of time using as a reference the detection of a magnetic marker (10) by the measurement unit (2), and the tag reader (34) shortens the communication time by ending the communication depending on whether information has been read from the wireless tag (15).
(FR) La présente invention concerne un système de véhicule (1) permettant de détecter des marqueurs magnétiques (10) installés sur une route et communiquer sans fil avec des étiquettes sans fil (15) fixées aux marqueurs magnétiques (10), ledit système de véhicule comprenant : une unité de mesure (2) permettant de détecter les marqueurs magnétiques (10) par détection du magnétisme ; un lecteur d'étiquette (34) permettant d'exécuter un processus de communication par rapport aux étiquettes sans fil (15) ; et une unité de commande (32) permettant de définir une heure de début de communication, qui est le début du processus de communication exécuté par le lecteur d'étiquette (34). L'unité de commande (32) définit, en tant qu'heure de début de communication, un instant après l'écoulement d'une durée prescrite en utilisant en tant que référence la détection d'un marqueur magnétique (10) par l'unité de mesure (2), et le lecteur d'étiquette (34) raccourcit le temps de communication en terminant la communication en fonction du fait que des informations ont été lues à partir de l'étiquette sans fil (15).
(JA) 道路に敷設された磁気マーカ(10)を検出すると共に、磁気マーカ(10)に取り付けられた無線タグ(15)と無線で通信を行う車両用システム(1)であって、磁気を感知することにより磁気マーカ(10)を検出する計測ユニット(2)と、無線タグ(15)との間で通信処理を実行するタグリーダ(34)と、タグリーダ(34)による通信処理の始期である通信開始時点を設定する制御ユニット(32)と、を備え、制御ユニット(32)は、計測ユニット(2)が磁気マーカ(10)を検出した検出時点を基準とした所定の時間経過後を通信開始時点として設定し、タグリーダ(34)は、無線タグ(15)から情報を読み取り次第、通信を終了することで通信時間を短縮する。
