Abstract
(EN)
The travel system (1) is provided with: a traveling dolly (100) which travels on a predetermined trajectory (5); multiple access points, including multiple first APs (200) for wirelessly communicating with the traveling dolly (100) and multiple second APs (300) for wirelessly communicating with the traveling dolly (100) using different communication slots from those used by the first APs (200); and a controller (400) for receiving from the traveling dolly (100) location information (50) indicating the current location of the traveling dolly (100) via any of the multiple access points, and transmitting to the traveling dolly (100) a traveling instruction for controlling the travel of the traveling dolly (100). The traveling dolly (100) is provided with an interface (170) for wirelessly communicating with the first APs (200) and wirelessly communicating with the second APs (300) in the event of a failure in wireless communication with the first APs (200).
(FR)
Le système de déplacement (1) comprend : un chariot mobile (100) qui se déplace sur une trajectoire prédéterminée (5); de multiples points d'accès, comprenant de multiples premiers AP (200) pour communiquer sans fil avec le chariot mobile (100) et de multiples seconds AP (300) pour communiquer sans fil avec le chariot mobile (100) à l'aide de différents intervalles de communication à partir de ceux utilisés par les premiers AP (200); et un dispositif de commande (400) pour recevoir en provenance du chariot mobile (100) des informations d'emplacement (50) indiquant l'emplacement actuel du chariot mobile (100) par l'intermédiaire de l'un quelconque des multiples points d'accès, et transmettre au chariot mobile (100) une instruction de déplacement pour commander le déplacement du chariot mobile (100). Le chariot mobile (100) est pourvu d'une interface (170) pour communiquer sans fil avec les premiers AP (200) et communiquer sans fil avec les seconds AP (300) en cas de défaillance en communication sans fil avec les premiers AP (200).
(JA)
走行システム(1)は、所定の軌道(5)上を走行する走行台車(100)と、走行台車(100)と無線通信する複数の第1のAP(200)、及び、第1のAP(200)とは異なる通信スロットで走行台車(100)と無線通信する複数の第2のAP(300)を含む複数のアクセスポイントと、複数のアクセスポイントのいずれかを介して、走行台車(100)から走行台車(100)の現在位置を示す位置情報(50)を受信し、且つ、走行台車(100)の走行を制御するための走行指示を走行台車(100)に送信するコントローラ(400)と、を備える。走行台車(100)は、第1のAP(200)と無線通信し、且つ、第1のAP(200)と無線通信できない場合に第2のAP(300)と無線通信するIF(170)を備える。
