Investigation of a pantograph-catenary monitoring system using condition-based pantograph recognition

In recent years in China, the operating mileage and the number of vehicles in the electrified railway have increased. For the pantograph-catenary system, which is one of the key components of the vehicle system, an urgent problem is how to improve the level of service detection, diagnose faults, and propose safety monitoring to assure safe operation and decrease the cost of maintance and repairation. In this paper, the design process, the overall architecture, the function module, the fault diagnosis method, and the monitoring scheme for a monitoring system based on the pantograph are investigated and discussed. As an example, two specified faults are introduced to describe how to develop a monitoring scheme based on pantograph condition-based recognition.
