摘　　要：提出了一种基于飞利浦32位ARM7芯片LPC2292与89C51单片机的CAN-以太网远程测控系统的设计方案,LPC2292芯片作为主节点控制器,外扩10M网卡芯片RTL8019AS,实现CAN-以太网信息的相互转换,工业现场节点控制器则使用89C51单片机,同时外扩键盘显示电路,方便用户现场参数的输入输出,远程监控端采用VB编程,实现了以太网客户端的远程监控;实验表明,该系统结构简单,可靠性高,性能价格比较高,能很好地应用于一些中型/大型的远程监控/数据传输网络。Introduces an interlinkage project between CAN （Controller Area Network） bus and Ethernet based on Philips 32-bit ARM7 core Microprocessor LPC2292 and 89C521 chip. Major node controller uses Lpc2292 chip and message conversion is realized between CAN bus and ethernet , node in industrious field bus uses 89c51 chip, Discusstion is made on the design of the hardware interface of the measuring and controlling system . it shows that this design has advantages of simple, reliable and cheap for its function , it will be well used in large remote measuring and controlling and data transmission network .
