摘　　要：为解决我国不同型号动车组在重新编组或解编后存在的互通、互联和互操作问题,开展既符合IEC 61375-1标准、又符合UIC 556标准的UIC网关关键算法和软硬件系统架构的研究。UIC网关的关键算法包括UIC初运行、过程数据编组(PDM)和UIC映射服务(UMS)等算法,分别用于实现动车组网络控制系统的动态编组、多功能车辆总线(MVB)与绞线式列车总线(WTB)间的双向周期性数据传输以及初运行算法的调用,并通过E报文的收发向用户提供服务;UIC网关的硬件系统由主机、通用外围电路、WTB和MVB通信存储器以及控制器等组成;UIC网关在Nucleus实时操作系统的调度下,通过运行TCN协议栈和UIC协议栈软件,实现WTB链路层、MVB链路层、消息数据和过程数据的通信。In order to solve the problem in interconnection, intercommunication and interoperability among different types of EMUs at re-marshalling or after uncoupling in China, the key algorithms as well as the system architectures for both the software and hardware of the UIC gateway in accordance with both IEC 61375-1 and UIC 556 standards have been studied. The key algorithms of UIC gateway include UIC inau- guration, Process Data Marshalling （PDM）, UIC Mapping Server （UMS）, etc. Among which, UIC inau- guration is to realize dynamic marshalling of EMU network control system; PDM is to realize two-way transmission of the periodic data between Multifunction Vehicle Bus （MVB） and Wire Train Bus （WTB） ; UMS is to call inauguration algorithms and provide the user with application service through transmit/re- ceive of E-telegrams. The hardware system of UIC gateway consists of main processor, general peripheral circuit, WTB traffic store, MVB traffic store, communication controller and so on. Under the scheduling of the real-time operating system named Nucleus, the communications of WTB link layer, MVB link layer, process data and message data are realized through running the TCN and UIC protocol stack software.
