Study of EMU Process Data and Message Data Communication Technology in UIC Gateway and Simulation
Tong Zhang, Changxian Li, Haoli Ping · 2015
UIC556 standard formulates the mechanism and mode of inauguration, process data and message data communication in the UIC gateway of EMU detailed. As the main EMU communication data stream, process data and message data must be effectively processed and converted with the help of the node monitoring database configuration, then can be transferred to the WTB (MVB) bus correctly. In this paper, comprehensive and detailed analysis of communication theory and software architecture of process data and message data were given in the UIC gateway of EMU. Two important media of process data and message data within the gateway are process data marshalling and UIC mapping server. Process data marshalling mainly achieve filtering and calculation of data between WTB and MVB, marshalling type, operating procedures and marshalling framework were deeply researched. UIC mapping server and TCN protocol stack provide the best path and a variety of services. The transmission mechanism of message data in the gateway and the composition and function of each part of UIC mapping server were detailed analyzed. By semi-physical simulation platform, the theory above is simulated and verified.
