Research Of The Inauguration Technology In High Speed Train Communication Network Marshalling

With the rapid development of the world's high-speed emu technology and people's life rhythm speeding up, high speed emu is a national railway developed one of the important indicators, therefore, to develop the high speed emu passenger dedicated line transportation mode is one of the main direction. In high-speed emu network control is the core of the emu. Marshalling and reconciliation of inauguration is the most basic and most critical part of network control, the train of message data, process data and monitoring data of normal communication play an immeasurable role. But our country's high-speed emu reconnection settlement made up by different manufacturers and the restriction of equipment technical fortress, it is difficult to implement different manufacturer production of magnetic reconnection inauguration of the emu. So early in the research of UIC556 inauguration technique is to solve high-speed emu truly interconnected, communication, interoperability of the trend of The Times is imperative.Based on the network control system inauguration after high-speed emu dynamic grouping as the research object, High-speed emu was designed and implemented the dynamic construction of the early marshalling inauguration process simulation development platform. Standard and UIC556 standard of IEC61375-1 is analyzed, and emphatically analyzes the inauguration of the standard theory, Analyzed from the perspective of application of IEC61375-1 and UIC556 standard TCN inauguration and UIC inauguration within the relevant theoretical knowledge.This article first introduced on high-speed emu the development status of both at inland and abroad. Followed by detailed analysis of the network control system in the inauguration of the main equipment gateway. After careful study of UIC556 standard protocol, this paper studies UIC inauguration algorithm, head of the vehicle, UCI address allocation, node reference direction, the integration of nodes, the determination of NADI state. Finally, put forward the implementation scheme marshalling and reconciliation of high-speed emu, through the hardware-in-the-loop simulation platform realizes the algorithm part of inauguration parameters configuration and software simulation, and through the software to complete the driver display reconnection early after operation interface design, finally get some results, through the MVB bus displayed inauguration result on the HMI, and inauguration after the reconnection to facilitate early operation after the reconnection process clear.
