摘　　要：设计了基于虚拟仪器技术的CAN总线转接器。以单片机和SJA1000 CAN总线控制器为核心构成下位机通信模块;以LabVIEW为开发平台,设计了上位机控制软件;上位机通过串口与下位机通信,实现上位机对CAN总线上的数据监测,还可以实现上位机向CAN总线各节点发送数据。实践表明此转接器具有一定的适用性,可以应用于某些CAN总线系统中。This paper designed a CAN bus adaptor which based on virtual instrument technique. It took single-chip and SJA1000 for the core components of the lower level computer communication module. It designed a PC control software with Lab- VIEW. PC communicates with lower level computer through a serial port, so that the PC can transmit data with each node of CAN bus system. Practice shows that this adapter has certain applicability, and can be applied to some CAN bus system.
