Automatic Generating Algorithm for accessing table of Computer Interlocking System

The paper analyzed the attribute and position of signal equipment by reading the based date of the station, made the railway signal equipment be position correlation, thereby established a station-type data structure of Computer Interlocking System, put forward an Automatic Generating Algorithm for accessing table of Computer Interlocking System based on station-type data structure. The Algorithm was combined with topology map and binary tree. The description for the Algorithm was given in detail.
