Title (EN) OPTICAL COMMUNICATION SYSTEM FOR RAIL-GUIDED TRUCK
(FR) SYSTÈME DE COMMUNICATION OPTIQUE POUR CHARIOT GUIDÉ SUR RAIL
(JA) 有軌道台車用光通信システム
Abstract:
(EN) This optical communication system for a rail-guided truck is provided with: a first communication system that communicates first information from a controller to a truck; and a second communication system that communicates second information from the truck to the controller. The first communication system comprises a first light emitting element that outputs the first information, a first optical fiber that transmits light outputted from the first light emitting element while leaking the light to the outside, and a first light receiving element that receives the light leaked from the first optical fiber, and the second communication system comprises a second light emitting element that outputs the second information, a second optical fiber that transmits light generated by light outputted from the second light emitting element and inputted from midway along the optical fiber, and a second light receiving element that receives the light transmitted by the second optical fiber.
(FR) L'invention concerne un système de communication optique destiné à un chariot guidé sur rail qui comprend : un premier système de communication qui communique des premières informations d'un dispositif de commande à un chariot ; et un second système de communication qui communique des secondes informations du chariot au dispositif de commande. Le premier système de communication comprend un premier élément électroluminescent qui émet les premières informations, une première fibre optique qui transmet la lumière émise par le premier élément électroluminescent alors que la lumière fuit vers l'extérieur, et un premier élément de réception de lumière qui reçoit la lumière qui a fui à partir de la première fibre optique, et le second système de communication comprend un second élément électroluminescent qui émet les secondes informations, une seconde fibre optique qui transmet la lumière générée par la lumière émise par le second élément électroluminescent et entrée à mi-chemin le long de la fibre optique, et un second élément de réception de lumière qui reçoit la lumière transmise par la seconde fibre optique.
(JA) 有軌道台車用光通信システムは、コントローラから台車へ第1情報を通信する第1通信系と、台車からコントローラへ第2情報を通信する第2通信系と、を備え、第1通信系は、第1情報出力する第1発光素子と、第1発光素子で出力された光を外部に漏洩させながら伝送する第1光ファイバと、第1光ファイバから漏洩した光を受光する第1受光素子と、を有し、第2通信系は、第2情報を出力する第2発光素子と、第2発光素子で出力されて当該光ファイバの途中から入力した光によって発生した光を伝送する第2光ファイバと、第2光ファイバが伝送した光を受光する第2受光素子と、を有する。
