Abstract

It is the trend to realize OCS (Overhead Contact System) switches' centralized interlocking monitoring with the development of electrified railway. According to extensive investigation and study on the situation at home and abroad, this centralized interlocking monitoring system of OCS switches based on FSO (Free Space Optical communication) was developed. In this paper, the system structure and working principle are described in detail, the design of relevant hardware and software is given, and the control of FSO by local center is especially discussed. The system runs well during test, and it has bright prospect of application and popularization.
