Abstract
The train network control system offers control,monitoring and diagnosis functions of EMU.To address the issues of low redundancy among the existing network system components of EMU,discontinuation of spare parts,and inadequate technical support for CRH380CL EMU,research has been conducted on autonomous substitution at the system level based on the existing network topology while ensuring that the stability and functionality of other subsystems will not be compromised.This approach enables the substitution of the TCN network topology for the existing ATI topology network;completes the research and test verification of key technologies including autonomous hardware development and test verification,system and equipment redundancy improvement design,RS485 gateway development and subsystem interface conformance test,complete transplantation of software such as control logic and display interface,and hardware-in-the-loop simulation platform test,etc.;guarantees the whole-life network system technology and spare parts support for EMU,solves the problem of low redundancy of existing components,and at the same time can upgrade software and hardware autonomously as well as to expand new technologies and functions such as PHM in the future,which reduces the utilization and maintenance cost of the network system in the whole life cycle.
