The feasibility of using the CANopen protocol as the rail transit vehicle bus is analyzed in principle and verified by experiments.All-layer protocols of CANopen and MVB are compared and analyzed.Combining with the characteristics of CAN and CANopen protocols,the set of network scheduling mechanism based on static scheduling algorithms(RM) and the CANopen protocol is established.Through theoretical analysis and example calculation,the results prove that the CANopen network using this network scheduling mechanism can achieve MVB performance;and the feasibility of using the CANopen protocol as the rail transit vehicle bus is also proved in principle.Through building the test platform and simulating the actual vehicle networking and data,experiments are carried out.The test data and waveforms prove that CANopen based on this set of network scheduling mechanism can achieve MVB performance,so CANopen working as the rail transit vehicle bus is feasible.
