分布式机械CAD系统中确定性信息处理方法

The processing methods of assured information in distributed mechanical CAD system

为解决基于网络的机械CAD系统中输入输出数据、表格、图形与图像、公式、线图等确定性信息的处理问题,通过数据分析,应用了网络数据库存储管理计算数据、数表、图形和图像信息;应用了正则表达式方法编制网络工程计算器;此外,应用了插值、多项式拟合、数学形态学和人工神经网络等方法对设计线图进行优化处理,以提高CAD系统取值的精确性。

to solve the processing problems of the assured information, which is input and output data, data tables, CAD files and images, formula, charts and so on in network based mechanical CAD system, by analyzing these data, the network-database was used to store and manage calculating data, data tables, CAD files and images etc. The method of regular express was used to program the network-engineering calculator. Moreover, the methods of interpolation, polynomial fitting, mathematical morphology, artificial neural network （ANN） were applied to optimum process of the CAD charts to improve the precision of value gotten by the CAD system.
