基于OPC规范的数据采集系统设计--毕业论文.doc

文档介绍：摘要
数据采集是分布式数控(DNC)系统的一个重要功能。随着制造自动化和企业信息化的发展,企业对自动采集制造信息的需求越来越强烈。
首先,本文结合学校安装的DNC数据采集系统,提出制作一个建议数据采集器的思想。根据所采集数据的要求确定了项目的具体方案。然后,对制作的数据采集器硬件部分按照串口调试、联调、连上机床信号的联调三个阶段进行分阶段的调试。在调试的过程中,介绍了数据采集器程序语言的工程建立和编译后下载到数据采集器的过程。最后,结合OPC服务器的一个二次开发平台SIACON-SmartOPC了解了基于面向过程控制的对象连接与嵌入(OPC)的数据采集实现共享的过程。在总结和展望中,就所学的专业知识和现实的DNC系统提出了如何实现软硬件集成的方案,并分析了DNC系统未来发展的趋势。

Abstract
Data acquisition is an important function of Distributed Numerical Control(DNC) the rapid development of manufacturing automation and enterprise information,the requirements of enterprises to gather manufacturing information automatically e more and more intense.
At first,this binations the Data Acquisition system fixed by the ChangChun university of technology and proposes an idea of making a Data Collector . According to data collected by the project,determined the specific then,the Data Collector is debugged with 3 steps including serial port debugging、Serial Server debugging and debugged online. In the process of debugging, the paper presents the process of the Data Collector downloads the program from establishing last, Combinationed a Secondary development platform of the OPC Server, comprehend OPC(OLE for Proeess Control)- based data acquisition prospect and outlook,processed a integrated method of the soft and the hardware with the Professional knowledge and the reality DNC system.
Keywords: DNC System Data Collector OPC
