【摘要】：生产信息管理系统能够有效地降低企业运行成本，提高企业的工作效率，对企业发展具有重要意义。数据采集系统则是实现生产信息管理系统的重要组成部分。OPC技术作为一套通用型、开放式的数据访问软硬件接口标准，已被广泛应用在工业控制领域。基于OPC技术的数据采集系统已经在PC机上得到成熟的应用。由于PC机体积大和功耗较高，不能满足现在工业控制朝着轻量级方向发展的需求，而嵌入式系统以其独立设备的形态出现，因其体积小、专用性强、结构简单、实时性高等特点得到广泛的应用。.NET平台是微软开发的新一代技术平台，以其简单易用、功能强大得到快速发展。因此，研究基于.NET的嵌入式系统下开发OPC客户端程序具有重要的工程应用价值。本文在结合OPC客户端发展现状和存在问题的基础上，提出了一种基于.NET的嵌入式系统OPC客户端开发的方法，该方法给出了嵌入式平台定制的方法，配置工具的编译和移植方法以及基于.NET的OPC数据采集程序开发方法。给出了一种支持OPC规范的WinCE系统设计和实现方法，该操作系统基于OPC规范和DCOM技术实现了远程访问OPC Server的功能。针对嵌入式系统下OPC数据采集程序存在的问题，给出了一种基于.NET的嵌入式系统OPC客户端程序的实现方法，，该方法使用COMInterop技术完成了对远程OPC服务器的初始化功能，使用ADO.NET技术实现了对大量实时数据的采集和转存功能。实验表明,基于.NET的嵌入式系统OPC客户端可以稳定、有效地对远程OPC服务器进行数据采集并运用ADO.NET技术完成数据的传输。该系统为基于OPC的数据采集提供了一套新的解决方案，具有很好的工程应用价值。
[Abstract]:The production information management system can effectively reduce the operation cost and improve the efficiency of the enterprise, which is of great significance to the development of the enterprise. Data acquisition system is an important part of the production information management system. OPC technology, as a set of universal and open interface standards for data access software and hardware, has been widely used in the field of industrial control. The data acquisition system based on OPC technology has been applied in PC. Because of the large volume and high power consumption of PC, it can not meet the demand of the development of industrial control towards lightweight now. However, embedded system appears in the form of independent device, because of its small size, strong specificity and simple structure, the embedded system has the advantages of small size, high specificity and simple structure. NET platform is a new technology platform developed by Microsoft, which is easy to use and powerful. Therefore, it has important engineering application value to study the development of OPC client program based on. Net embedded system. In this paper, based on the development of OPC client and the existing problems, a method of developing embedded system OPC client based on .NET is put forward, and the method of customizing embedded platform is given. The compiling and porting method of configuration tool and the developing method of OPC data acquisition program based on .NET. This paper presents a design and implementation method of WinCE system which supports OPC specification. The operating system realizes remote access to OPC Server based on OPC specification and DCOM technology. Aiming at the problems of OPC data acquisition program in embedded system, this paper presents a realization method of embedded system OPC client program based on. Net. The method uses COMInterop technology to complete the initialization of remote OPC server. The function of collecting and transferring a large amount of real-time data is realized by using ADO.NET technology. The experiment shows that the OPC client of the embedded system based on. Net can collect the data of the remote OPC server effectively and use the ADO.NET technology to complete the data transmission. This system provides a new solution for data acquisition based on OPC and has good engineering application value.
