Performance Analysis and Optimization of Train Control Network Based on Industrial Ethernet

Abstract

The traditional Ethernet communication technology is analyzed, because of uncertainty of media access and data communication, there are some problems for traditional Ethernet applied in train control network. Reference to the characteristics of TCN MAC protocol, the time division multiplexing channel method based on time-triggered mechanism was introduced to improve the train network scheduling mechanism and ensure Ethernet’s real-time and deterministic communication. Then, the real-time analysis and calculation were carried out, and the simulation model was completed on the OPNET simulation platform. The simulation results demonstrated the feasibility and effectiveness of the proposed approach.
