基于DNA模式的分布式OPC监控系统构架

Distributed OPC Monitoring System Frameworks Based on DNA Model

提出了基于DNA模式的OPC分布式监控系统构架。以OPC技术为核心,实现了表现层、逻辑层及数据层的三层WindowsDNA构架。该系统采用DCOM为基础,OPCXML为数据交换标准,支持实时信息转发、实时数据存储及网络对象管理等功能。实践证明:该分布式监控系统具有高实时性、快速、成本低,同时具有较好的实用性。

Distributed OPC Monitoring Systems Based on DNA Model were presented. The monitoring systems utilized OPC technologies as cores and implemented a windows DNA three-tier structure including data/logical/application tiers. Based on DCOM and OPC XML schema, the system can route information, storage real-time information and manage networks objects. The results of field applications show that the novel distributed monitoring systems have good real-time, capability and reliability.
