摘要
为了在面向物联网的应用中,完成对RFID读卡器以及传感器模块数据的网络传输,设计并实现了一个基于ARM7的以太网终端平台。针对低成本嵌入式系统资源匮乏的问题,提出了把浏览器请求当作函数调用的办法,在平台上实现了动态网页服务。该平台硬件部分采用ATMEL公司AT91SAM7X512微处理器作为主控芯片,软件部分通过移植LwIP协议栈并调用其API实现了TCP客户端和WEB服务器。平台在取得数据后主动向上位机请求连接并传送数据,上位机可通过网页对平台进行访问和设置。
In order to communicate with the RFID module and the sensors through Ethemet, an low-cost Ethemet terminal based on ARM7 is designed and implemented in this paper. A method for implementing a dynamic WEB page server on the low-cost embedded systems is also presented. In the proposed method, the platform can respond the browser＇s requests with corresponding functions so that the dynamic WEB page is well presented to the users. The platform sent a request to the host for a connection after obtaining the data, and the host can use a WEB page for accessing and setting toward the platform.
