Electromagnetic compatibility design of multi-sensor based train integrated positioning system

With the rapid development of the intelligence and complication to railway systems, there are increasing demands of electromagnetic compatibility performance for train borne system, where the electromagnetic compatibility performance of train positioning system (TPS) is crucial to the design process of the entire system. In this paper, the system architecture of TPS integrating multi sensors is introduced, based on the overall design of the multi-sensor based train integrated positioning system, the electromagnetic interference of the TPS is analyzed at the power module, communication module, transmission and PCB routing, then the electromagnetic compatibility solutions are introduced in hardware and software. Lab test of the TPS validates the performance with proposed strategies.
