摘要
主要设计具有三层或多层结构的分布式测控平台。通过对用户的安全认证、多用户的数据并发访问控制以及远端机器的访问控制等,构建高效率的、坚固安全的,具有容错能力和负载平衡能力的网络分布式测控平台。运用COM/COM+(ComponentObjectModel,组件对象模型)和DCOM(D istrib-uted COM,分布式COM)等组件技术,将数据显示浏览、数据采集处理、数据库管理等逻辑彻底地分离,使系统耦合松散、可复用、易扩展、升级维护方便。真正地满足资源共享、远程数据采集、数据管理等需求,实现虚拟化实验和工业测控环境。
A distributed tri -tier or multi -tier architecture based on C/S （Client/Server） was implemented in Test and Control system in this paper. Through user＇s security authentication, users＇ multi - access control and far equipment access control, the system can achieve high efficiency and security, Fault -Tolerance and Load Balancing functionality, and using COM/COM ＋ （Component Object Model） and DCOM （Distributed COM） software technical, it can separate data displaying, data sampling or acquisition, data management from each other in logic, in order ego make system reusable, expandable and easy updating. The network platform can really accomplish remote test and control and data processing on the Intranet or Internet.
