【摘要】：随着城市的发展、各类生产生活服务设施的完善和人们生活质量的提高,远程监控技术逐渐渗透到电力、通讯、交通、安保、生态监测等领域。远程监控的大规模应用对远程监控网络提出了新的要求。 在比较了多种监控网络优缺点后,为了缓解大规模远程监控网络构建成本和系统功能之间的矛盾,提出了基于单片机的Web远程监控系统方案。该方案采用B/S结构,由用户端、系统管理服务器和监控节点组成。系统管理服务器基于PC平台,具有用户身份验证、节点定向、网络管理、数据库支持、客户端软件下载等功能。监控节点基于单片机,由Web服务器和监控模块、外围电路组成,具有数据采集、处理、发布和控制的功能。 监控节点的Web服务器是网络实现的重点,本文分别针对嵌入式实时操作系统μC/OS-Ⅱ和无操作系统两种环境,研究了Web服务器的实现,主要完成了以下工作：1、选择合适的TCP/IP技术,在无文件系统支持下实现了网页发布；2、提出了虚拟CGI的概念,建立了用户端与服务器端之间的动态交互；3、结合AJAX技术和ActiveX控件,在不增加服务器负担的前提下,丰富了用户端界面的动态显示。其中无操作系统的方案有利于进一步降低系统成本,有操作系统的方案可应用于任务复杂的系统。 考虑到远程实验与远程监控在技术上的一致性,本文以Web远程实验室为平台,研究了加热炉温度控制远程实验。实验结果表明,该嵌入式远程实验系统达到了过去基于PC系统的实验效果,验证了Web监控网络的可行性。
[Abstract]:With the development of the city, the improvement of all kinds of production and living service facilities and the improvement of people's quality of life, remote monitoring technology has gradually penetrated into the fields of power, communication, traffic, security, ecological monitoring and so on. The large-scale application of remote monitoring puts forward new requirements for remote monitoring network. After comparing the advantages and disadvantages of various monitoring networks, in order to alleviate the contradiction between the construction cost of large-scale remote monitoring network and the system function, a scheme of Web remote monitoring system based on single-chip microcomputer is proposed. This scheme adopts B / S structure and consists of client, system management server and monitor node. The system management server, which is based on PC platform, has the functions of user authentication, node orientation, network management, database support, client software download and so on. The monitoring node is composed of Web server and monitoring module, and has the functions of data acquisition, processing, publishing and control. The Web server of the monitoring node is the focus of the network implementation. In this paper, the implementation of the Web server is studied for the embedded real-time operating system 渭 C / OS- 鈪，
