摘　　要：USBCAN总线转换设备作为USB总线和CAN总线之间的连接设备,其运行状况和软件设计是否能达到设计的需求,一般的方法很难进行验证,本文通过在Stateflow工具箱下对一种USBCAN总线转换设备进行建模,并且在Matlab/Simulink环境下对整个转换设备运行状态进行仿真验证,实现了USBCAN总线转换设备运行状态的验证,提出了一种新的总线转换设备的仿真和验证方法。The USBCAN bus converter is a connector of USB bus and CAN bus.It is difficult to judge whether the device works well or not and meets design requirement or not by ordinary ways.Regarded the Matlab/Simulink/Stateflow toolbox as the platform,the model of a USBCAN bus converter is established.The model of the bus converter is tested and verified in the Matlab/Simulink simulation environment.The results of the simulation analysis show the model is suitable for simulating the working state of the device.A new simulation and judging method for bus converters is proposed.
