The title and bill of material in engineering drawings are important data source for product data integrated management. In order to reuse the CAD data, the paper presents an effective method for extracting part information from existing engineering drawings. Through analyzing the format of title and bill of material, several shape-position characteristics of tables are summed up from the view of macro-layout and microstructure. A new method to automatically extracting drawing information based on cell-grid and feature-point is proposed along with its algorithm principle and implementation steps. A software package based on the method mentioned above is developed and used in practice.

1引言工程图是工程设计的主要成果和制造加工的主要依据，CAD软件的广泛应用使得传统上对于纸质图纸的管理模式转变为对大量电子文件的管理模式·由于文件系统在实际应用中不能适应复杂大规模的管理模式，已经出现了各种各样的图档管理系统[1]·工程图中包含的零件信息在表现形式上体现纸格式的标准化为批量提取数据提供了可能性·作为计算机处理的对象，图纸信息自动识别成为数据管理和系统集成的一项关键技术·当前CAD管理系统所处理的数据对象比较复杂，面临由不同企业使用不同的绘图软件生成的图纸，其中的标题栏和明细栏或者由软件自动生

With the rapid development of the research on computer and various related fields,and the rise of the research and application in the visualization of science computation and multimedia technology, digital image processing changed from a special field subject into a tool of a new science research and human-computer interface.

前言在日常生活中，图像处理已经得到广泛应用。例如，电脑人像艺术，电视中的特殊效果，自动售货机钞票的识别，邮政编码的自动识别和利用指纹、虹膜、面部等特征的身份识别等。早期的计算机无论在计算速度或存储容量方面，难于满足对庞大图像数据进行实时处理的要求。

在工业控制过程中，继电接触器控制系统因其没有运算、处理、通讯等功能，而不能完成复杂的控制方式，20世纪60年代PLC控制系统应运而生，它综合了计算机技术、自动控制技术和通信技术等现代科技，是当今工业自动控制的标准设备之一；70年代以后，又相继出现了集散控制系统DCS、现场总线控制系统FCS，现在以及今后很长一段时间内会是三种控制方式并存的局面，在这一背景下该文分析PLC控制的现状及发展前景。
