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。 Aiming at the variety of mechanical and electrical products, it is difficult to trace the quality of the unqualified products, and a type of mechanical traceability system based on OPC is designed. The complexities and technical difficulties of product quality traceability are pointed out. The technical specifications, technical essence, data exchange principle and data access interface of OPC are discussed. The framework of product quality traceability system is researched. An OPC based electromechanical product traceability system is designed. Taking the monitoring of software system interconnection as an example, this paper establishes a system to verify that the seamless integration of heterogeneous systems based on OPC can overcome the information silos puzzle caused by the incompatibility between device diversity and drivers. Practice shows that: OPC-based quality tracing system has a wide range of applications.
