摘　　要：为了增加CAN总线的实际应用范围,研究并设计了一种基于无线通信芯片nRF905的CAN总线智能节点。首先,介绍基于无线通信的CAN总线控制系统结构;然后,设计以nRF905无线通信芯片、MSP430F149微处理器和CAN总线控制器为核心的智能节点电路;最后,给出相应的软件控制流程。实验结果表明,设计的节点能可靠有效地收集数据。A design method of intelligent node based on nRFg05 for CAN bus was proposed in order to increase the application fields of CAN bus. Firstly, a CAN-Bus control system based on wireless communication was presented. Secondly, It took nRFg05, MSP430 and CAN controller as the cores, designed the hardware. Finally, the system software was introduced. The test results show that the designed node can correctly gather data by wireless mode.
