Crane CAN Bus Modeling and Simulation Based on Stateflow

Introduce CAN bus communication processes and arbitration techniques. Build a crane CAN bus communication model with transmitting nodes in State flow environment. Prove the feasibility of using Matlab/Simulink/Stateflow module in simulating CAN bus and analyzing bus performance. The CAN bus model includes bus state transition diagram, priority arbitration function and state transition diagrams of each sending nodes. The simulation results are reflected by waveforms in Scope. The waveform diagrams show the situation that bus occupied by nodes and the influence on nodes´ waiting time of different transmission period. Using State flow to simulate Crane CAN bus and analysis factors that influence bus performance has been proved feasible through the simulation.
