摘　　要：介绍了基于USB的CAN总线适配器结构;给出了USB接口与CAN总线之间的转换模块的硬件设计方法,以及模块初始化程序、USB处理程序及CAN总线处理程序的流程图。设计中综合考虑软件和硬件的功能要求,有效的提高了适配器的实时性,稳定性和抗干扰性。USB-based CAN Bus communication adapter's construction is introduced. The system's hardware structure and design methods between USB interface and CAN bus are designed in detail. The program flow diagram of initialization procedure, USB-process procedure and CAN bus-process procedure are also discussed. The design considers synthetically the function request of software and hardware, improves the adapter's capacity for real-time, stability and anti-interference.
