【摘要】 实现接触网开关的集中联锁监控是铁路电气化发展的必然趋势。在大量调研国内外发展现状的前提下,研制了一套基于FSO(free space optical communication,自由空间光通信)的接触网开关集中联锁监控系统。详细地介绍了该系统的组成结构、工作原理、硬件构成及软件设计,并重点论述了现场总站对FSO的控制方式。系统试验运行良好,具有广阔的应用和推广前景。更多还原

【Abstract】 It is the trend to realize OCS(overhead contact system) switches′ centralized interlock monitoring with the development of electrified railway.Based on the extensive investigation and study on the situation at home and abroad,this centralized interlock monitoring system of OCS switches based on FSO was developed.The system structure and working principle were described in detail,the design of relevant hardware and software was given,and the control mode of FSO by local center was especially discussed.The system runs well in the test,and it has extensive prospect of application and popularization.更多还原
