Abstract
(EN)
It is possible to provide a radio tag communication device and a radio tag communication system which can rapidly check existence of a plurality of radio tags which have been listed in advance. The radio tag communication system includes: a communication control unit (72) which selectively establishes a first communication mode in which information is communicated between all the radio tags (14) contained in a list which defines the predetermined radio tags (14), as communication objects and a second communication mode in which at least one of the radio tags (14) corresponding to the specified identifier is used as a communication object and information is communicated with the radio tag (14); and a switching judgment unit (71) which judges switching between the first communication mode and the second communication mode according to a predetermined parameter from a predetermined switching condition. Thus, in communication for checking existence of the radio tags (14) which have been listed in advance, it is possible to switch the communication by specifying an identifier based on the check process and accordingly, it is possible to effectively perform communication with an unidentified radio tag (14).

L'invention porte sur un dispositif et un système de communication à marqueurs radio pouvant rapidement vérifier l'existence de plusieurs marqueurs radio listés à l'avance. Ledit système comporte: une unité de commande de communication (72) qui établit sélectivement: un premier mode de communication dans lequel l'information est communiquée à tous les marqueurs radio (14) contenu dans une liste qui définit les étiquettes de radio prédéterminées (14), en tant qu'objets de communication, et un deuxième mode de communication dans lequel l'un au moins des marqueurs radio (14) correspondant à l'identificateur indiqué est utilisée consiste en tant qu'objet de communication, l'information étant communiquée avec le marqueur radio (14); et une unité de jugement (71) jugeant si on doit commuter entre le premier mode et le deuxième mode en fonction d'un paramètre prédéterminé et à partir d'une condition prédéterminée de commutation. Ainsi en communiquant pour vérifier l'existence des marqueurs radio listés à l'avance, il est possible de commuter la communication en précisant un identificateur sur la base du processus de vérification, et donc d'exécuter effectivement la communication avec un marqueur radio (14) non identifié.

 予めリスト化された複数の無線タグの存在を可及的速やかに確認し得る無線タグ通信装置及び無線タグ通信システムを提供する。  複数の無線タグ14を定義するリストに含まれる全てのタグを通信対象としてそれら無線タグ14との間で情報の通信を行う第1の通信モードと、指定された識別情報に対応する少なくとも1つの無線タグ14を通信対象としてその無線タグ14との間で情報の通信を行う第2の通信モードとを、選択的に成立させる通信制御部72と、予め定められた切換条件から所定のパラメータに基づいて前記第1の通信モード及び第2の通信モードの切換判定を行う切換判定部71とを備えたものであることから、予めリスト化された複数の無線タグ14の存在を確認するための通信において、その確認の進行に応じて識別情報を指定しての通信に切り換えることができるため、未確認の無線タグ14との間で効率的に通信を行うことができる。
