摘要
针对电器智能化网络开放性、灵活性、可靠性的要求,开发了基于ARM微处理器的智能电器接入以太网的联网服务器。利用32位ARM微处理器搭建了以太网联网服务器的硬件平台,并将嵌入式实时操作系统μC/OS-Ⅱ移植到设计好的硬件平台上,然后在μC/OS-Ⅱ上移植了开放源代码的TCP/IP协议栈LwIP,扩展了μC/OS-Ⅱ对网络的支持,完成了软件平台的设计及网口转串口和串口转网口应用程序的开发,实现了智能电器设备快速联网的基本功能。并开发了嵌入式Web服务器、Telnet远程配置程序和网上在线更新程序等基于网络应用的程序,在一定程度上实现了以太网通信的智能化功能。
Aiming at the requirements of intelligent electrical apparatus network for the openness, agility and reliability,an Ethernet network server is developed,which applies 32-bit ARM microprocessor as its hardware platform. The embedded real-time operating system uC/OS-Ⅱ is transplanted to the prepared hardware platform as the software platform and LwIP,the open source TCP/IP stack,is then transplanted to the uC/OS-Ⅱ to support network application. The conversion programs from Ethernet to serial and vice versa are designed for the connection between intelligent electrical apparatus and Ethernet. Furthermore, applications based on network are developed to realize intelligent Ethernet communication,such as embedded Web servers,Telnet long-distance configuration and online updating.
