基于 ARM 的嵌入式远程监控系统的设计与实现
摘要
随着嵌入式系统及其相关技术的迅猛发展,概念
的提出,远程监控系统领域出现了一个新的发展趋势,那就是利用嵌入
式Web技术来实现远程监控系统。本文在这样的背景下,结合石油、化
工、冶金和电力等领域对阀门进行远程监控的迫切需要,探讨了基于嵌
入式WEB技术的远程监控系统的实现方法,并利用该系统成功实现了
对阀门执行机构的远程监控。本文主要完成了以下工作:
1、基于 HHARM9200 开发平台,采用嵌入式 Web 技术实现了 B/S
方式
的远程监控系统,有效解决了工业现场设备的接入问题。通过
该系统,用户可以直接通过浏览器对现场设备进行远程监控,
这种监控方式将成为未来一段时间内工业监控的发展方向。
2、利用自行开发的无线通信终端实现了基于 GSM 短消息平台的无
线远程监控系统,有效解决了工业监控中,由于监控点分散而造成的组
网困难问题。该系统充分利用了 GSM 短消息平台传输成本低、可靠性高、
使用方便等特点,在实际使用中取得了良好的效果。

3、基于数据采集系统芯片 ADUC812 设计了智能阀门定位器,有效解
决了过程控制领域国产阀门电动执行机构控制精度不够、可靠性不高、
缺乏必要通信手段的问题。该定位器借助 ADUC812 强大的数据采集功
能,控制精度可以达到千分之五。该定位器还具有 RS485 通信功能,满
足对多个阀门进行组网控制的要求。

THE DESIGN AND IMPLEMENTATION
OF A REMOTE MONITORING EMBEDDED SYSTEM
BASED ON ARM PLATFORM
ABSTRACT
With the rapid development of technologies concerning embedded
systems and the emergence of the concept of embedded , a new
research orientation, the implementation of remote monitoring by applying
embedded technologies, is getting focused in the remote monitoring
field. With such a background, this paper, considering the great need of
remote monitoring systems in oil, chemical, metallurgical and power
industries, discusses a method of making up a remote monitoring system
based on embedded web technologies and eeds in having a valve
activator under remote monitoring.
The main results of this paper are described as follows:
1. The setup of a embedded web server on HuaHeng Embedded System
Developing Platform makes it possible for the field devices to have a direct
connection to and offer field information as a server. The field
devices can be controlled through LAN or as they have been directly

connected to .
2. Wireless terminal based on GSM is involved to decrease the difficulty
of building work covering all the distributed points to be monitored.
Thus, wireless r
