Rapid rate train communication network system for processing instrumentation data

Abstract

In this paper we propose a new train communications network (TCN) system for processing instrumentation data collected between vehicles that have a very rapid data rate.
Now there are many TCN for communication available to control devices in a train, which have a data rate of 10k-1Mbps (bits per second). But we need a faster data rate for instumentation data, when we conduct a track test of MAGLEV (Magnetic Levitation Vehicle). In this case, we handle several hundreds of sensors on the train and collect synchronized data for structure analysis and vehicle dynamics analysis after the test.
We have developed a new TCN system for collecting synchronized instrumentation data consisting of a huge digital data-recorder and an optical-fiber train bus. This system treats a data rate of 32Mbps. And we have developed all devices, protocol, optical-module, optical-connectors and so on.
