Abstract As fiber optic cables,fiber jumpers,photoelectric converters and other communication equipment and materials are added to the signal transmission lines of the new automatic weather station with optical fiber transmission,faults will be more difficult to troubleshoot if the communication line is not accessible.Taking a fault caused by a short circuit of the data bus from the new automatic weather station of Lianping national basic meteorological observation station as an example.This paper introduces the phenomenon of its failure,analyses of elimination process and summarizes the experience and methods that should be paid attention in troubleshooting and daily maintenance,which can be used as a reference for technical personnel of the station.
