The design about Train Control Network which based on CAN bus
Abstract: In view of the current Chinese national conditions, this paper compared the advantages and disadvantages of other train communication network, at the same time combined with CAN bus which have high communication rate, high reliability, high cost performance and connection is very convenient, so design of train communication network which based on CAN bus. Completing the design of train communication network architecture, through the OPNET software, set up the simulation platform. Among them, the heart of the simulation is the CAN node design, including CAN bus node domain model, the process model of  Input_output and mac_can, this paper focuses on the design of this part of the structure and parameters. For the whole model, using the word and picture at same tine to show the how to build the whole project. At the same time, studied the design scheme by simulation test, like the transmission rate with the average delay of the information transmission or throughput, average load with information transfer delay or throughput and bit error rate and the relationship between the bit error rate and the bus load or throughput, demonstrate the reliability of the scheme.
