In view of the characteristics of large amount and great scale

complex structure and increasingly high fault incidence of modern power communication network

a fault location intelligence analysis method for the electric power communication network is proposed. The adoption of intersection operation for the fault multi-level location and the combined fuzzy logic operation to locate the faults in the carriers for the information signal is a good choice. By using this method

the fault can be accurately and quickly located on the position

physical device

logical circuit

and communication transactions

improving the operation maintenance and management level of the electric power communication network.
