【摘要】 随着对工业控制技术、微电子技术及计算机技术研究的不断深入,工业控制系统的数据采集和数据管理水平也得到了很大的提高。本文着重介绍的热电厂外循环水的数据采集和管理系统是在热电厂外循环水PLC控制系统的基础上构建了SCADA(计算机监控及数据采集)和数据管理系统,实现了对数据的采集、传输、监视、控制和管理。本论文各章节内容简述如下: 第一章首先阐述了本论文研究的背景和目的,对近年来数据采集和管理系统的发展进行了综述,之后根据系统实际要求提出了论文所要完成的研究内容和主要任务。 第二章具体介绍了设计系统时下位机的硬件选型和程序设计,根据系统实际控制需要构建了系统的下位机部分。 第三章首先对工业控制网络进行了综述,在此基础上讨论了用两种不同的工业控制网络来构建系统,并最终从实际出发选择了更适合本系统的网络。 第四章详细介绍了如何构建热电厂外循环水SCADA系统,并运用了多种计算机数据交互技术,实现了对系统数据的监视、控制、共享、交互。 第五章具体介绍了系统数据管理的实现。 最后,对热电厂外循环水系统的数据采集和管理进行总结,本文的研究对国内工控行业中类似的应用有一定的参考价值。更多还原

【Abstract】 With the development of industrial control, microelectronics and computer technology, the data collecting and handling level in industrial control system have been greatly improved. In this article, the data acquisition and management system of the cycling water in heat power plant is detailed described, which is based on PLC control system. The system is constructed by SCADA(Supervisory control and data acquisition) and data management system, providing data collecting , transferring, monitoring, controlling and management. The article is made up of 6 chapters and sections and a brief description is given as follows:Chapter 1 presents the background and goals of this article and summarizes the development of the data acquisition and management system in late years.Chapter2 introduces the hardware selection and the logic design according to the requirements of the system.Chapter3 gives an introduction to Industry Control Network, makes comparison between two kinds of networks and determines which network is used in terms of actual needs for this application.Chapter4 presents how to construct a SCADA system in the heat power plant, where several technologies of data exchanging are used to implementing supervising, controlling, data sharing and exchanging.Chapter5 focuses on the implementing of the system database.Chapter6 gives a summary of the data acquisition and management system of the cycling water system in heat power plant.更多还原
