摘要
随着列车网络控制系统中使用的电子控制设备不断增多,设备间的协作兼容问题也日益突出。为了保证网络系统中不同的电子控制设备(包括系统标准划分的子模块)能相互协同正确操作,同时减少其附加的开销,网络设备一致性测试受到了越来越多开发人员的关注。文章依据原本针对汽车电子系统开发的AUTOSAR标准规范,引入TTCN-3(Testing and Test Control Notation 3)国际标准测试语言,实现列车控制设备参照AUTOSAR标准的以太网TCP/IP协议栈一致性测试,验证列车设备制造开发过程中TCP/IP协议与标准的相符性。
With the increasing use of electronic control equipment in train network control system,the problem of cooperation and compatibility between the equipment is becoming more and more serious.In order to ensure the correct operation of different electronic control devices(including sub-modules of system standard division)and reduce their additional overhead,network equipment conformance testing has been paid more and more attention by developers.This paper introduces TTCN-3(Testing and Test Control Notation 3)international standard Test language according to AUTOSAR standard specification originally developed for automotive electronic system,and realizes the Ethernet TCP/IP protocol stack conformance testing with reference to the AUTOSAR standard of the train control equipment,Verify the compliance between TCP/IP protocol and standards in the process of train equipment manufacturing and development.
