摘要
针对工业控制领域设备信息化网络化存在不足的问题,本文采用NXP公司ARM7系列的LPC2378为微控制器设计出一种在μC/OS-Ⅱ操作系统下完成基于TCP/IP协议的一个以太网口,4个符合16C550工业标准的异步串行口UART0-3,和2个CAN局域网控制接口间进行协议转换的通信控制器。从而为传统的串口设备,工业控制中常用的CAN接口设备,以及与目前更加通用的网络接口之间的信息资源相互之间的通信提供了一种实用的低成本解决方案。
In order to improve the defects in the information and network of the equipments used in the field of industrial control, a embedded system on ARM7 LPC2378 micro-controller is presented, with μC/OS-Ⅱ, a conversion of three kind of serial port data including an ethernet port in the TCP/IP, four UART0-3 ports and two CAN ports is implemented,which provides a practical and a low-cost solution for traditional serial interface equipments to intact to the mternet.
