摘要
为了实现以太网与CAN总线的数据交换,构建了一个基于嵌入式的CAN总线与以太网互连系统。系统硬件平台以LPC2119 ARM7为核心,包括由ENC28J60构成的以太网接口模块、CAN接口模块、HMI接口模块;系统软件平台使用了实时操作系统μC/OS-II和嵌入了LwIP协议栈,并用VC++设计了上位机人机界面。实验调试结果表明,该系统在智能断路器上运行稳定可靠,具有一定的实用性和推广价值。
In order to realize Ethernet and CAN bus＇s data conversion, Constructed a interconnect system based on embedded technology between CAN bus and Ethemet. Hardware platform of the system let LPC2119 ARM7 as the core, including Ethemet interface module based on ENC28J60, CAN interface module and HMI interface module; Sottware platform used real-time operating system uC/OS-II and embedded LwlP protocol stack. Tho PC user interface was designed by VC＋＋. Experimental debugging results showed, stable and reliable operation of system on voltage circuit breaker, will have certain practicability and commercial worth.
