【摘要】 随着因特网技术快速发展，因特网在社会的各个领域得到了大量应用。在远程控制技术方面，因特网的介入，将会大大推动远程控制技术的发展。 本文首先对远程控制进行总体分析，认为一个远程控制系统应该由监控、传输、现场监控三个子系统构成；并从控制方式、影响控制正常运行的因素以及远程设备的接入技术三个方面对一个远程控制系统进行了一定程度的探讨。 接着，本文从理论角度对基于因特网的远程控制技术进行了研究，分析了实现基于因特网远程控制所采用的数据传输策略和控制策略。 在上述研究的基础上，根据开发因特网应用的方式，本文将基于因特网的远程控制技术分为基于TCP／IP协议的远程控制技术和基于WEB的远程控制技术来研究。 1．基于TCP／IP协议的远程控制技术采用C／S网络模型的，本文分析了这种远程控制技术的特点，在实现层面上将基于TCP／IP协议的远程控制系统划分为监控、通信客户、通信服务器和现场监控四个功能模块，对每个模块进行了详细的研究，并采用VC++开发了基于TCP／IP协议的远程控制系统软件。 2．基于WEB的远程控制技术是以B／S网络模型为基础，实现远程控制的一种技术。本文分析了这种远程控制技术的特点，提出了一个三层体系结构模型(监控层／数据管理层／数据采集与控制层)，并对该体系结构进行了较为详细的描述。最后开发了基于WEB的远程控制系统软件。更多还原

【Abstract】 With the development of Internet, it is applied more and more widely in different fields. The remote control will be improved for the Internet utilized.Firstly, this paper makes researches on remote control systems. It presents that a remote control system can be composed of three subsystems- monitoring terminal, transmission and online control. A detailed research on a remote control system is conduct from three aspects, which are control methods, factors influencing system operation performances and technology of access to equipment.In succession, the paper studies theoretically the Internet-based remote control system. And some strategies of control and data transport are researched.On the bases of the above, it is concluded that there are two methods to carry out the Internet-based remote control technology, which is the TCP/IP-based remote control technology and the WEB-based remote control technology.1. The TCP/IP-based remote control technology adopts C/S model. The paper analyzes this technology in the first place, then the remote control system can be divided into four parts, which are monitoring and control, client, sever, and online control. And every part of them is designed. Eventually, the software about the remote control system is developed.2. The WEB-based remote control technology is another kind of method, which applies B/S model. As analyzing characters of the remote control, we bring forward three-layer structure of the system, which includes the layer of monitoring and control, the layer of data and the layer of online control. In the end, the software about the web-based remote control system is accomplished.更多还原
