【摘要】 近年来,网络技术的不断发展,尤其是以TCP/IP为代表的Internet技术的发展,给远程监控网的实现提供了深厚的技术基础。 将传统的监控系统与Web技术相结合的B/S(浏览器/服务器)模式下的计算机远程监控系统逐渐成为新的研究和开发热点。本论文以Internet技术的发展为基础,在深入研究TCP/IP体系结构及其各种相关技术的基础上,主要对基于Internet的远程实时监控系统的关键技术进行了深入系统的研究,通过对不同软件结构的比较,在现有控制网络的基础上构建了一个B/S模式的远程实时监控系统。其中包括:远程监控的Web化方案设计,控制网络与信息网络的融合,实时数据动态交换及实时性研究,远程监控系统的网络安全等。同时以远程实时监控系统的方案为基础,设计了一个远程温度监控系统的ActiveX控件(包含WinSock控件),实现了温度状况参数设置、历史查询、实时监控等功能。 以实现网络的实时数据交互为目标,本文研究了基于B/S模式的网络远程实时监控技术。由于控制网络与信息网络的技术要求与特点不同,对如何实现控制网络与信息网络的融合进行了分析和研究。对数据动态交换及实时性问题进行了介绍和分析,对比了几种主要的动态交换技术,并详细分析了ActiveX技术在远程监控系统中的使用。对远程监控系统的实时性进行了研究,并在现有条件的基础上提出了一些提高系统实时性的措施和方法。在监控系统的设计中,根据实时性的不同对数据进行分类,分别采用两种方式(Socket和数据库)实现数据的远程通信,并使用OPC接口实现对实时数据的采集。网络安全在系统中占有非常重要的地位,本文对网络通信中的基本安全技术进行了阐述,提出了一些加强网络安全的措施。更多还原

【Abstract】 In recent years, the rapid development of network technology Especially with the development of the Internet technologies with TCP/IP as the leading role, remote monitoring network has been supplied a more profound technological foundation.The Computer’s Remote Monitoring System based on B/S model which combines the traditional remote monitoring system and Web technology attracts more and more attention on research and development. Based on the development of Internet technology, the thorough study of TCP/IP structure and relative technologies, the paper makes a deep research on the key technology of the real-time remote monitoring and control system and design a real-time monitoring and control system based on B/S model according to the comparison of different software modes. Among them, the design of a Web-based monitoring and control project, the integration of the Infranet network and Internet/Intranet network, the real-time data dynamic exchange and the research of real-time character and network security of the remote monitoring and control system are included. Based on the real-time remote monitoring and control system, an ActiveX control(including WinSock control)used in remote temperature monitering and control system is designed to realize the functions such as configuration of temperature status parameter ,history inquiry and real-time remote monitoring and control.In order to realize the real-time data dynamic exchange, some methods to improve real-time capability of B/S-based remote monitoring and control system are analyzed and studied in this paper. Because of the differences of the request and characteristics between Internet/Intranet technology and Infranet, how to realize the integration of the Infranet and Internet/Intranet was analyzed and studied. Data dynamic exchange and real-time question were introduced and analyzed, several dynamic exchange technologies were mainly compared, and the use of ActiveX technology in the remote monitoring and control system was analyzed in details.This paper also studies the real-time characteristics of the remote monitoring and control system, and puts forward some methods to improve real-time capability of the system depending on existing conditions. In the design of the remote monitoring control system, the remote data communication is realized by two methods (Socket technology and database technology) according to the different character of real-time data and OPC technology is used for data acquisition from local control unit. Network security occupies a very important position in the system. The paper introduces the basic network security and presents some methods to make Internet communication safer in B/S model.更多还原
