OPTICAL RADIO COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To prevent deterioration in transfer performance without increasing the number of transfer frames in a system configuring a two-way communication network with optical radio, especially in an optical radio communication network for exchanging an information frame through an optical node installed in a traveling object and a plurality of optical repeaters of a wired system network.

SOLUTION: A plurality of optical repeaters AP1 and AP2 having a function for switching information frames are arranged on a ceiling or the like, and an optical node for performing two-way communication with the optical repeaters AP1 and AP2 is mounted on a traveling object such as a truck. A relaying device 5 for periodically transmitting an information frame including a self-station address from an information processor connected with the optical node to the optical repeaters AP1 and AP2 by optical radio and having a filter function for making information frames from the optical repeaters AP1 and AP2 to a trunk network 3 continuously flow and making only one information frame with the same contents effective is provided.
