传统OPt服务器基于COM／DCOM组件技术，导致其不仅依赖于Windows平台．而且在网络数据传 输及安全性方面也存在一定的技术缺陷。基于OPC统一架构(UA)标准解决这类问题。同时将传统OPC系列功能集成到一个OPC服务器上，简化及方便了各功能的协作和企业的部署。采用微软Net的代码托管技术．模块 化构建了OPC UA服务器的开发框架，设计实现了地址空间、安全配置等基本模块及功能。采用服务器地址空间的节点、引用等核心技术，设计实现了地址空间的节点管理、数据管理、访问管理、订阅管理和视域管理等 功能类．设计完成了独立的OPC UA地址空间功能模块-OPt traditional server based on COM/DCOM technology, resulting in not only dependent on the Windows platform. And in network data transmission and safety, there are some technical defects. Standard solve such problems based on OPC Unified Architecture (UA). While the traditional OPC series features integrated into one OPC server to simplify and facilitate the collaboration and enterprise deployment of each function. Net managed code using Microsoft' s technology. The modular construction of the OPC UA server development fr a mework designed to achieve the basic modules and functions address space, security configuration. Using node server address space, references and other core technologies, designed to achieve the node address space management, data management, access management, subscr iption management and category management functions sight. Design completed the independent functional modules OPC UA Address Space
