摘　　要：根据某测试任务的要求,对CAN传输的可靠性进行调研和分析,设计了一种基于PXI总线的CAN适配卡。以PCI9054为"桥接"芯片,以FPGA为核心控制器实现上位机与CAN接口的通信。以C8051F060作为CAN总线的核心控制器实现CAN数据收发、缓存及编帧等功能。该适配卡可靠性高,已稳定工作于某航天测控系统。A CAN adaptor card has been designed according to the test task requirements based on PXI bus after the research and analysis of the reliability of CAN transmission. The PCI9054 was used as the＂bridge＂chip and FPGA was used as core controllers to implement the communication between upper computer and CAN interface. The C8051F060 was used as the core device of the adaptor card to achieve the following functions,such as the command issued,the reception,the cache and coding of CAN date and so on. The card was put into service in a space measurement and control system depending on its high reliability.
