Abstract

Abstract: In order to realize the CAN bus communication with PC and remote monitoring, a design method of the embedded Ethernet-CAN communication transform card based on FPGA was proposed. The design chose the embedded soft processors Nios Ⅱ in FPGA as the main control chip, MCP2515 as the CAN bus controller and 88E1111 as the Ethernet PHY chip. A system hardware model was built with the SOPC (System-On-a-Programmable-Chip) technology, and the CAN controller, Ethernet initialization and the Ethernet-CAN conversion process were completed in the Nios Ⅱ IDE （Integrated Development Environment）.The experimental results show that the design completely meets the requirements of the Ethernet and CAN bus communication.

Key words: Field Programmable Gate Array (FPGA), Controller Area Network （CAN） bus, embedded Ethernet, TCP/IP protocol, AC servo driver

摘要： 为实现CAN总线与PC通信，便于CAN总线数据的远程监控，提出一种新的基于现场可编程门阵列（FPGA）的多路CAN总线转Ethernet接口方案，以嵌入FPGA的NiosⅡ作为主控制器，MCP2515为CAN总线控制器，88E1111为以太网PHY芯片。利用可编程片上系统（SOPC）技术搭建了系统的硬件模型，在NiosⅡ IDE软件开发环境中，完成CAN控制器、以太网初始化和Ethernet-CAN转换程序。以数控系统中交流伺服驱动器为应用背景，实验结果表明：该转换卡完全满足以太网和CAN总线通信要求，方便地将CAN总线数据接入工业以太网，用户通过网络可方便地实现对工业底层的监控。
