METHOD FOR FORMING RING MAP DATA AND METHOD FOR GENERATING INFORMATION RELATED TO ISOLATION AND SEPARATION OF RING

摘要

PURPOSE: A method for forming ring map data and a method for generating the information related to the isolation and separation of a ring are provided to establish the data of a ring phase, by adopting a duplicate connection list structure in order to easily check the isolation and separation isolation and separation thereof in a two-line ring network. CONSTITUTION: It is checked if the unique number of a from-node equals to that of a to-node(201). If the two numbers equal to each other, the unique number of the to-node is inserted into a list(SqNodeList)(202). If the two numbers do not equal to each other, the unique number of the from-node is stored in a variable(i)(203). The data stored in the variable(i) is compared with the unique number of the to-node(204). If the data does not equal to the unique number of the to-node, the variable(i) is inserted into the list(SqNodeList)(205). If the node is a west node(206), a node in a west direction of the variable(i) is updated(207). If the node an east node, a node in an east direction of the variable(i) is updated(208). If the data equals to the unique number of the to-node, the variable(i) is inserted into the list(SqNodeList)(209).
