基于嵌入式Web的远程抄表系统研究与设计

Research and Design of Remote Meter Reading Systems Based on Embedded Web

给出一种远程抄表系统的解决方案,构建了基于ARM的硬件平台,重点介绍CAN总线接口的设计和嵌入式Linux开发环境的构建,分析了嵌入式Web服务器的工作流程、HTTP协议和CGI程序,从而实现把采集到的电量数据通过CAN总线传送到Web服务器,然后由Web服务器通过Internet传送到远程客户端的抄表过程。

This paper presents a solution for remote meter reading system,bulits an ARM-based hardware platform,focuses on the design of CAN bus interface and building the embedded Linux development environment,analyses the work flow of embedded Web server,HTTP protocol and CGI programs,so that to realize the meter reading process that send the collected power data to Web server through the CAN bus,and then send to the remote client over the Internet by Web server.
