近十年来,随着互联网技术飞速发展,以太网成为商业通信中的主导网络技术。工业以太网技术就是将以太网技术应用在工业领域的互联网技术。文中基于ARM7处理器平台,将TCP/IP协议嵌入到嵌入式系统中来实现系统的网络通信功能。具体内容包括网络模块的硬件设计和软件设计。硬件设计包括网络控制芯片和外围电路设计,软件设计包括底层驱动程序设计和TCP/IP协议移植。该系统适用于具有遥信、遥测、遥控功能的水利、电力调度、市政调度等行业。
Over the past decade, with the rapid development of Internet technology, Ethernet has become the dominant network technology in commercial communications. Industrial Ethernet technology is the Internet technology that uses Ethernet technology in the industrial field. The article based on ARM7 processor platform, the TCP / IP protocol embedded in the embedded system to achieve the system’s network communication capabilities. Specific content includes the network module hardware design and software design. Hardware design includes network control chip and peripheral circuit design, software design includes the underlying driver design and TCP / IP protocol migration. The system is suitable for remote control, telemetry, remote control of water conservancy, power dispatching, municipal dispatch and other industries.
