摘　　要：OPCUA网关对外部系统提供统一标准的数据接口,是智能制造应用领域的关键产品。针对OPCUA网关的数据存储问题,设计了一套内存与外存协同的数据存储系统。摒弃商业数据库软件,直接基于内存与外存进行数据操作。定义了应用于OPCUA结点数据的内存存储结构与外存存储结构,并在此结构的基础上设计了网关数据写入与读取的流程。该系统在Raspberry Pi3B硬件平台上实现,并与成熟的数据库系统进行对比测评。实验结果表明,该系统在数据的读、写以及硬件资源使用率等方面均有较好的表现。The gateway based on OPCUA provides a unified standard data interface for external systems,which is a key product in the application field of intelligent manufacturing. Aiming at the data storage problem of OPCUA gateway,a data storage system based on random access memory and external storage was designed. The system abandons the commercial database software and operates data directly based on random access memory and external storage. The random access memory storage structure and external storage structure which are applied to OPCUA node data were designed,which is foundation of the process of gateway data writing and reading. The system was implemented on raspberry PI3 B hardware platform and was compared with the mature database. The experimental results showed that the system had good performance in data writing,reading and hardware resource utilization.
