Development of an FPGA-based Online Condition Monitoring System for Railway Catenary Application

초록

The aim of this paper is to develop a Field Programmable Gate Array (FPGA)-based online condition monitoring system for sensor network applications in railway catenary systems. The system is designed to perform in IP network-based wireless environments and is capable of storing data in a live wire state at 25 kV. A real-time controller, chassis (including a reconfigurable FPGA), and several I/O modules re used in the condition monitoring system. To check the validity of our approach for the intended application, we monitored temperature, vibration, strain, and displacement in the overhead wire of a high speed catenary system in Korea.
