LI Guoru

Abstract

In this paper, the programmable controller techniques were mentioned, which were used in signal control system of railway locomotive depot to implement interlocking function. The system structure, redundancy mode, software structure, classification and transfer of PLC interlocking software, program idea were analyzed. The System was proved to be a high performance-price ratio system for locomotive depot.
