During this thesis , we do a deeply research in oop technology , ado technology and com technology , and discuss some database modeling technologies . in this project . the realization of the graphic interface takes emf technology . because of some algorithm properities of emf element , oop technology is used to discribe the spot facilities and to adjust these facility shapes . in this system . we use a linked list to organize all of the facility ' s shapes , so that we can not only identify each shape but also raise system ' s run - time efficiency
在本课题里，采用了增强图元文件技术( enhancedmetafile )实现变电站的可视化操作界面。通过利用增强图元文件对自身元素的算法描述特性，实现了对现场设备对象化描述及元素的大小的调整及缩放。对于操作界面中的各个设备元件本系统采用了链表的方式进行组织，这样有利于实现设备图形的区分，并且可以提高系统的运行效率。
