Abstract
A method for implementing fault diagnosis by means of a spread spectrum carrier includes the following steps: designing incident signal parameters, selecting a spread spectrum sequence for fault detection, determining a center frequency and a sequence length of a spread spectrum code, and segmenting and transforming a power carrier source signal; using the fault detection spread spectrum sequence as a carrier spread spectrum code, and performing spread spectrum modulation on the transformed power carrier source signal to generate an SSPLCR sequence; coupling the SSPLCR sequence to a cable to be tested, and when the cable works normally without failure, transmitting the SSPLCR signal to the receiving terminal via the cable; when the cable fails, reflecting the SSPLCR signal back to the transmitting terminal.
