OPTICAL DATA TRANSMISSION DEVICE, OPTICAL COMMUNICATION DEVICE, AND AUTOMATIC CONVEYANCE DEVICE

摘要

Reliable data transmission is secured without inviting large design changes by means of configuring the disclosed optical data transmission device (100) in a manner so as to be provided with: data conversion units (210, 310) and optical communication control units (220, 320) that transmit to each of a first communication unit (200) and a second communication unit (300) disposed movably relative to one another an optical signal modulated in response to wired data input from a wired line (13a), and that output wired data demodulated from the received optical signal to the wired line; a bit data input unit (240) that receives input of bit data for emergency stops; a bit data output unit (340) that outputs bit data for emergency stops; and bit data communication control units (250, 350) that control in a manner so as to transmit/receive input bit data via the optical communication control units (220, 320) using optical signals that are isolated from the optical signal corresponding to the wired data.
