摘　　要：在VxWorks操作系统下对TRDP协议栈移植遇到的问题进行分析与解决,介绍了在TRDP(Train Real-time Data Protocol)应用过程中遇到数据发送失败时的应对方法,最后指出了目前VxWorks 6.5版本FTP组件中普遍存在的后门问题。经过两年的验证,超20万公里运用考核,在机车车辆网络控制系统中应用该协议栈所遇到的问题及其解决方法,可以证明移植成功,方法可靠,值得推广。Firstly,in the VxWorks operating system,the problems encountered in the train real-time data protocol(TRDP)stack transplant are analyzed and solved,and the solutions to the failure of data transmission in the process of TRDP application are encountered.Finally,the common backdoor problem in the current VxWorks 6.5 version FTP component are pointed out.After two years'verification,and assessment of the application of over 200 thousand kilometers,the problems encountered in the application of the protocol stack in the locomotive and vehicle network control system and the solution in the application of the protocol stack in the locomotive and vehicle network control system can prove that the transplant successes,the method is reliable,and it is worth popularizing.
