一类基于OPC的机电产品质量追溯系统设计

摘要

针对机电产品种类繁多难于对不合格产品进行质量追溯，设计了一类基于OPC 的机电产品质量追溯系统。指出了产品质量追溯的复杂性与技术难点，讨论了OPC 的技术规范、技术本质、数据交换原理与数据访问接口，研究了产品质量追溯系统框架，设计了一个基于OPC 的机电产品质量追溯系统。以监控软件系统互连为例，搭建系统验证了基于OPC 的异构系统无缝集成可克服由于设备多样性与驱动程序不兼容性导致的信息孤岛难题。实践表明：基于OPC 的质量追溯系统具有广泛的应用前景。%Aimed at the puzzle of being difficult to carry through the quality traceability for the unqualified prod-ucts resulted in a great variety of electromechanical products,the paper designed a kind of quality traceability sys-tem of electromechanical products based on OPC.In the paper,it pointed out the complexity and technology diffi-culty of product quality tracing,discussed on the technical specification,the essence of technology,the principle of data exchange and the data access interface,researched on the framework of product quality traceability sys-tem,and designed a quality traceability system of electromechanical products based on OPC.Taken the intercon-nection of monitoring software system as an example,it built the system which demonstrated that the seamless in-tegration of heterogeneous system based on OPC could overcome the puzzle of information islands resulted in de-vice diversity and driver incompatibility.The practice shows that it has a broad prospect of application to the qual-ity traceability system based on OPC.
