The application discloses an intelligent digital signal wire distribution device which is arranged at each node station in a digital signal wire network. The intelligent digital signal wire distribution device comprises an acquisition unit, a main control unit and a wire distribution unit. The acquisition unit automatically detects the communication state of a communication line associated with the corresponding node station; when determining that a certain communication line fails according to a detection result, the main control unit controls the wire distribution unit to switch digital signal wires of the communication line, so that the communication failure is eliminated, and normal communication between the corresponding node stations is ensured. Therefore, according to the intelligent digital signal wire distribution device provided by the embodiment of the application, the digital signal wires of a power communication network can be automatically maintained, the probability of misoperation is reduced, the communication maintenance efficiency is improved, and the problems in the prior art are solved.
