农业机械图形符号微机管理系统的设计与开发

DESIGN AND DEVELOPMENT OF A MICRO-COMPUTER SYSTEM FOR MANAGING THE GRAPHICAL SYMBOLS OF AGRICULTURAL MACHINERY

根据农业机械图形符号的构形特点、使用要求,设计出一套适合计算机处理、按功能和应用分类的分类编码方案;研究提出图符图形信息与数据信息配合使用的方法;运用计算机绘图技术和信息处理技术建立农机图符图形库、数据库及其管理系统。同时,对AUTO CAD 进行二次开发,设计出用于运行农机图符库管理系统以及用于快速、高质量绘制农机简图和示意图的几个新指令。

Techniques and methods of computer managing the graphical symbols of agricultural machinery (abbreviated as GSAM) were researched preliminarily.For computer processing,a classifying and encoding project in accordance with functions and applica- tions was designed according to the configuration characteristics and application require- ments of GSAM.A method combining figures with data information was also put forward, based on which the GSAM figure and data bases with management system were set up,us- ing computer graphical techniques and information processing techniques.In line with the demands of running the GSAM management system and drawing schematic diagrams or schemes for agricultural machinery in quick speed and good quality,a deep development of AUTO CAD was made,and some new commands were created.
