基于嵌入式系统的智能节点在CAN总线中的应用

Based on embedded system's intelligent node in field bus's application

针对现有的网络智能节点工作的稳定性低和时实性差,设计了一种基于S3C44B0X的智能节点在CAN总线控制网络,是将嵌入式系统应用于CAN总线控制网络中,从而提高网络的稳定性和时实性;给出了智能监控节点的硬件电路、软件软初始化程序和通信流程。经系统测试和实际运行表明,该系统安装、使用方便,可靠性较高,达到了设计要求,具有一定的参考和推广价值。

In view of existing network intelligent node work stability low and bus control network real-time bad,the design one kind based on the S3C44B0X intelligent node in the CAN bus control network research and the application,is applies the embedded system in the CAN bus control network,thus enhances the network the stability and bus control network;has given the intelligent monitoring node hardware circuit,the software soft initialization process and the correspondence flow.Indicated after the system tests and the actual run; it indicated that this system installation the easy to operate, the operational reliability to he high, has achieved the design requirements.
