Real-time Online Monitoring Scheme for Additive Conductors of OCS Based on Distributed Optical Fiber Sensing Technology
The faults of additive conductors in railway OCS are characterized by challenges in early detection,high sporadic occurrence,and significant difficulties pinpointing their location.These issues directly impact the operational reliability of the OCS system and pose potential risks to safety during operations.This paper proposes a solution that involves the installation of optical fiber composite additive conductors and the establishment of a monitoring system.By utilizing distributed optical fiber technology,the system can monitor the operational status of the additive conductors in real time and facilitate train location tracking.The discussion primarily focuses on the three aspects:the scheme of monitoring system,conductor monitoring,and the monitoring of train operating status.This monitoring scheme offers several advantages,including high sensitivity,extended monitoring range,and immunity to environmental constraints,such as those presented by tunnels.It enables real-time monitoring of major faults in the overhead additive conductors of OCS,as well as real-time monitoring of train operating status,thereby enhancing O&M efficiency and safety reliability.Additionally,it provides the essential technical support for the development of an intelligent OCS system,featuring capabilities such as real-time monitoring,evaluation,and alarm notifications.
