The implementation of CAN—Ethernet communication system on the missile simulation and detection platform

With the advantages of high speed, high efficiency and low error rate, CAN-Ethernet is used to achieve the interconnecting communication in the research of a certain kind of missile simulation and detection platform. The CAN-Ethernet bridge is designed by utilizing the development board with the LPC2210 microcontroller as the core to achieve the mutual transformation between CAN data frame and Ethernet date frame, making possible the mutual circulation of the two heterogeneous networks. Furthermore, UDP data transceiver is used at the end of ethernet, to improve the transmitting efficiency of data. When the compiled software program is runned on this platform at last, it proves a good result, thus realizing the downlink of command and uplink of data. This paper discusses the design method of bridge, the design of various ports among hardware parts as well as the implementation of CAN bus communication.
