Title: Lan communication system
Inventor: KOGA YOSHIHIKO
IPC: H04B10/275
Filed: 1990-11-27
Abstract: PURPOSE:To prevent hit without switching an optical transmission line against a fault by letting the same data flow in the same direction to an active system and a spare system, executing communication while ORing the both data, and executing communication while shielding one data in the case of the fault. CONSTITUTION:Active system and spare system optical transmission lines 3 and 4 circulates the same data in the same direction, photoelectric conversion parts 11 and 12 of a communication node 2 executes the photoelectric conversion of a signal, and monitor parts 21 and 22 monitor an optical level. The outputs of the conversion parts 11 and 12 are transmitted to a selector part 13 and when a monitored result is normal, the signals are 0Red and outputted to a common part 14. When one signal is abnormal, the signal of the transmission line system is shielded and is not outputted to the common part 14. Therefore, when the transmission lines 3 and 4 are normal, the data is processed at the common part 14 and transmitted to a terminal later, and a data from the terminal is transmitted by the common part 14. Then, the data is divided into the active system and the spare system at a selector part 15, converted to an optical signal and transmitted. Thus, hit is prevented without switching the optical transmission line against the fault.

When the compared digital expression coincides within the range of an allowable error that is preliminarily defined, it is decided that a failure does not occur. When it does not coincide within the range of the allowable error, it is compared with one or more digital expressions in which abnormal acoustic outputs of the microphone 38 and the sensor 42 are stored. It is decided how and which part fails.
