基于嵌入式以太网的远程监控系统的设计与实现

Design and Implementation of a Remote Monitoring System Based on Embedded Ethernet

摘要:

为了以较低成本实现对环境和设备的远程监控问题，采用MSP430单片机和CS8900A以太网控制器设计了一种基于嵌入式以太网的远程监控系统。对系统的总体结构和软硬件设计进行了介绍。通过移植简化的TCP/IP协议栈实现了嵌入式以太网。将嵌入式网页存储于MSP430单片机的Flash存储器中，通过软硬件协同构建了嵌入式远程监控服务器。用户通过网络访问嵌入式网页可以随时查看和远程管理系统，从而实现对系统的远程监控。实验测试结果表明系统能够满足设计要求，系统设计方案是可行的。

Abstract:

In order to realize remote monitoring of environment and equipment at low cost, a remote monitoring system based on Embedded Ethernet is designed by using MSP430 Microcontroller Unit (MCU) and CS8900A network controller. The overall structure of the system and the design of software and hardware are introduced. Embedded Ethernet is implemented by transplanting simplified TCP/IP protocol stack. Embedded web pages are stored in Flash memory of MSP430 MCU, and an embedded remote monitoring server is constructed through hardware and software cooperation. Users can visit the embedded web pages to view and remote manage the system at any time through the network, so as to realize the remote monitoring of the system. The experimental results show that the system can meet the design requirements and the system design scheme is feasible.
