摘　　要：简要阐述HDLC网络基本通信原理的基础上,介绍了基于HDLC协议的列车网络接口单元的软硬件设计。硬件部分主要基于嵌入式CPCI总线和协议控制器SAB82532实现了通信网卡的设计;软件部分主要完成了HDLC通信网卡板级通道驱动软件和应用层通信软件的设计,并在此基础上,通过封装设计后的API驱动函数的调用,实现了实验室环境下HDLC通信测试功能。测试结果表明,设计的HDLC网络接口单元基本满足了通信要求,达到了预期目标。The design of hardware and software of train network interface unit based on HDLC protocol has been discussed on the basis of introducing the basic communication principle of HDLC network. The communication network card was accomplished by using flushbonding CPCI bus and SAB82532 protocol controller. Also, the board driver software and application software was designed, the HDLC communication test was completed in lab environment through calling the API function packaged by ourselves. Test result shows that this HDLC network interface unit meets communication requirement and achieves the expected goal.
