摘　　要：随着网络和信息安全、国际贸易摩擦等问题的不断出现,产品国产化及自主可控需求越来越强烈,在轨道交通领域的关键控制系统中将逐步采用国产化软硬件方案替代国外的方案。文章简要阐述了标准化地铁平台的国产化牵引及网络控制系统架构,重点描述了其国产化处理器、嵌入式操作系统、图形化开发软件等软硬件选型,详细介绍了牵引及网络控制系统的硬件方案、软件结构以及软硬件移植适配过程,对国产操作系统与VxWorks在功能和性能方面进行对比分析,并开展了牵引/电制动特性验证和网络组网等各项软件功能测试。结果表明,该国产化牵引及网络控制系统性能参数优良,运行稳定可靠,牵引/电制动特性正常,系统网络延时处于微秒级,抖动处于亚微秒级,满足标准化地铁平台需求,可实现100%国产化对等替代。With the continuous emergence of network and information security challenges,international trade frictions and other issues,the demand for localization,independence and controllability of products is becoming more and more intense.As a result,domestic hardware and software solutions will be gradually adopted to replace foreign solutions for the key control system in the field of rail transit.This paper briefly describes the architecture of the domestic traction and network control system for the standardized subway platform,and focuses on the selection of the hardware and software,such as CPUs,embedded operating systems and graphical development software.It also details the hardware scheme,software structure,and migration and adaptation process of the software and hardware for the traction and network control system,and makes a comparative analysis on the functions and performances of the domestic operating system and VxWorks.Through a series of software functional tests such as verification of traction/electric braking characteristics and networking,conclusions are drawn that the domestic traction and network control system features excellent performance parameters,stable and reliable operation,normal traction/electric braking characteristics,network delay of the system in microseconds,and jitter of the sub-microsecond level,which meet the requirements of the standardized subway platform,and therefore it can be used for 100%localization as an equivalent substitute.
