Study on Dynamic Marshalling and Coupled Control of China’s High-Speed Electric Multiple Unit

Abstract

In order to reduce operation cost and improve transport capacity of China high-speed railway, train dynamic marshalling often need to be implemented between different kinds of China’s high-speed Electric Multiple Units (EMUs). Based on the operation situation of China high-speed railway, this paper analyzes the market demand and feasibility of dynamic marshalling between different kinds of EMUs, and describes the principle how to realize it by using TCN and UIC network communication technology. Some key problems which need to be solved in the process of realizing coupled control between different kinds of EMUs are pointed out, and corresponding suggestions how to solve these problems are proposed as well. Moreover, according to the technical development trend of the EMU, this paper predicts the possibility of using network communication technology based on real-time Ethernet to realize EMU marshalling and coupled control.
