The invention provides an electrical communication system fault diagnosis method and device. The method comprises the steps of obtaining basic fault information of a target fault; obtaining a prestored electrical communication system fault case library, wherein the electrical communication system fault case library stores basic fault information, fault phenomenon description, fault reason deduction and diagnosis strategies of a plurality of fault cases; comparing the basic fault information of the target fault with basic fault information of each fault case in the electrical communication system fault case library, and determining the fault case with the target fault similarity exceeding the first preset similarity threshold value as a typical fault case from the electrical communication system fault case library; according to actual information of on-site faults, optimizing the typical fault case, and determining the optimized fault diagnosis case of the target fault; according to theoptimized fault diagnosi
