Abstract:In order to realize Ethernet and CAN bus’s data conversion, Constructed a interconnect system based on embedded technology between CAN bus and Ethernet. Hardware platform of the system let LPC2119 ARM7 as the core, including Ethernet interface module based on ENC28J60, CAN interface module and HMI interface module; Software platform used real-time operating system uC/OS-II and embedded LwIP protocol stack. The 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.
