INFORMATION TRANSMISSION SYSTEM AND INFORMATION TRANSMISSION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a highly reliable information transmission system capable of continuing transmission even when multiple failures occur. SOLUTION: Two bus transmission lines are provided and a transmission terminal is connected to both bus transmission lines. In the transmission, data are transmitted to both bus transmission lines. Each transmission terminal always checks a reception state. In the case that the data cannot be received in one of the bus transmission lines, the data flowing through the other bus transmission line are relayed to the bus transmission line by using a relay function.
