Design of Train Ethernet Consistency Testing Platform Based on IEC 61375 Standard

Abstract

Objective To ensure the stability, reliability, compatibility, as well as the accuracy of data transmission and control in train network systems, research on the consistency testing of train networks is needed. Method The design of the train Ethernet testing platform is based on the IEC 61375 standard and the construction of the testing platform is completed. The testing platform mainly consists of hardware and software platforms. The hardware platform includes testing instruments, companion devices, fixtures, and industrial control computers. The software platform is based on LabVIEW programming language, NI TestStand software testing framework, and Tcl scripting language for system integration. Result & Conclusion The automation testing of the physical layer, protocol layer, and performance of the train Ethernet is achieved, and certified by CNAS (China National Accreditation Service for Conformity Assessment).
