摘要

针对C R H 2 型动车组国产化制动控制单元的联网问题，分析了列车通信终端（Terminator）装置与制动控制单元（BCU）之间的通信方式，设计一种用于国产化BCU 的通信网关，实现列车通信终端装置(HDLC 协议)与国产化BCU（RS485 协议）的通信协议的转换。最后在进口BCU 试验台上，验证了通信网关功能的完整性。

Abstract

This paper introduced the networking problem of indigenous BCU for CRH2 EMUs and analyzed the communication mode between terminator and BCU. A communication gateway for indigenous BCU was designed and protocol conversion was achieved between terminator (HDLC) and BCU (RS485). The experiment which is based on import test bench verifies the integral function of the communication gateway.
