Title (EN) STATION-TO-CAR COMMUNICATION SYSTEM AND CONTROL METHOD
(FR) SYSTÈME DE COMMUNICATION DE STATION À VOITURE ET PROCÉDÉ DE COMMANDE
(JA) 駅車間通信システムおよび制御方法
Abstract:
(EN) This station-to-car communication system is provided with: a first wireless machine; a second wireless machine that communicates with the first wireless machine and is installed in a car; a third wireless machine that communicates with the second wireless machine and is installed in a station at which the car stops; and a control device that controls the first wireless machine and the third wireless machine. The control device transmits encrypted information to the first wireless machine and the third wireless machine, and the second wireless machine receives the encrypted information from the first wireless machine and starts encrypted communication with the third wireless machine using the encrypted information without performing authentication processing.
(FR) La présente invention concerne un système de communication de station à voiture qui comprend : une première machine sans fil ; une deuxième machine sans fil qui communique avec la première machine sans fil et qui est installée dans une voiture ; une troisième machine sans fil qui communique avec la deuxième machine sans fil et qui est installée dans une station à laquelle la voiture s'arrête ; un dispositif de commande qui commande la première machine sans fil et la troisième machine sans fil. Le dispositif de commande transmet des informations chiffrées à la première machine sans fil et à la troisième machine sans fil, et la deuxième machine sans fil reçoit les informations chiffrées de la première machine sans fil et démarre une communication chiffrée avec la troisième machine sans fil à l'aide des informations chiffrées sans effectuer de traitement d'authentification.
(JA) 本開示における駅車間通信システムは、第1無線機と、第1無線機との間で通信を行い、車両に設置される第2無線機と、第2無線機との間で通信を行い、車両が停止する駅に設置される第3無線機と、第1無線機および第3無線機を制御する制御装置と、を備える。制御装置は、暗号化情報を第1無線機および第3無線機に送信し、第2無線機は、第1無線機から暗号化情報を受信し、第3無線機との間で認証処理を行うことなく、暗号化情報を用いて暗号化通信を開始する。
