【摘要】 基于以太网的分布式测控系统已得到广泛应用,其最大优点是可实现上层管理的信息网络与底层测控网络的无逢连接,但是,以太网的实时性是影响测控系统数据传输的主要因素。根据以太网测控系统的实时性要求,提出了有利于提高系统实时性的多种技术措施,以及基于典型分布式测控系统体系结构模型的大容量数据缓存和多级分布式数据库实现技术,对工业应用与工程设计具有一定的参考价值。更多还原

【Abstract】 Ethernet-based DMCS(distributed measurement and control system) has been wildly applied. The best feature of this system is that it can be easily implemented in seamless integration of upper managing information networks and lower control networks, but its real-time performances are influenced by real-time performance of Ethernet. Various technical measures for enhancing real time performance of the system are put forward based on the demands of real time data transmission in Ethernet-based DMCS. Typical DMCS architecture mode and mass data storage and multilevel distributed data base implementation technologies based on the mode are explained. These are valuable as reference for engineering design and applications.更多还原
