Abstract:
(EN) A communication device in a communication system in which a communication device having the right to transmit transmits a frame, the communication device being provided with: a receiving unit (11) for extracting, from a received frame, information on a transmission interval that indicates the interval until the next time an adjacent communication device from which the received frame was transmitted transmits a frame; a receiving interval measurement unit (13) for measuring a receiving interval of frames successively transmitted from the adjacent communication device; and a communication fault detection unit (14) for comparing the receiving internal and the transmission interval information and detecting, when the receiving interval is larger, that a communication fault has occurred in communication with the adjacent communication device.
(FR) La présente invention concerne un système de communication dans lequel un dispositif de communication autorisé à transmettre transmet une trame, le dispositif de communication étant pourvu : d'une unité de réception (11) permettant d'extraire, d'une trame reçue, des informations sur un intervalle de transmission qui indiquent l'intervalle jusqu'à la prochaine fois qu'un dispositif de communication adjacent à partir duquel la trame reçue a été transmise transmette une trame ; d'une unité de mesure d'intervalle de réception (13), permettant de mesurer un intervalle de réception de trames transmises successivement à partir du dispositif de communication adjacent ; et d'une unité de détection de défaillance de communication (14) permettant de comparer l'intervalle de réception et les informations d'intervalle de transmission et de détecter, lorsque l'intervalle de réception est plus grand, qu'une défaillance de communication s'est produite dans une communication avec le dispositif de communication adjacent.
(JA) 送信権を持つ通信装置がフレームを送信する通信システムにおける通信装置であって、受信したフレームから、受信したフレームの送信元の通信装置である隣接通信装置が次にフレームを送信するまでの間隔を示す送信間隔の情報を抽出する受信部(11)と、隣接通信装置から連続して送信されるフレームの受信間隔を計測する受信間隔計測部(13)と、受信間隔と送信間隔の情報とを比較して、受信間隔の方が大きい場合、隣接通信装置との間の通信において通信障害が発生したことを検出する通信障害検出部(14)と、を備える。
