[0040] S04, executing the fault processing instruction after the service node confirms.

[0041] Through the above implementation, the original centralized feeder terminal cooperative processing is logically updated to distributed feeder terminal cooperative processing, thereby providing technical support for efficient line fault positioning.

[0042] In some embodiments of the present application, the feeder terminals having an access relationship with the service node are divided into a first type of node and a second type of node, comprising: selecting a plurality of feeder terminals as the first type of node based on the distance from the service node, and the remaining feeder terminals are the second type of node.
