CAD二次开发在铁路车站信号工程设计中应用的研究

摘要

Combined with the engineering design of CAD secondary development of all-electronic computer interlocking implementation unit module arrangement list and railway station interlocking tables, it was introduced the applications of Visual Lisp in engineering design of CAD secondary development of railway station signal including the whole ideas, benefits,data structures, processes of Visual Lisp in CAD secondary development.%结合CAD二次开发全电子微机联锁执行单元模块排列表和铁路站场联锁表工程设计,介绍Visual Lisp在CAD二次开发铁路车站信号工程设计中的应用,包括Visual Lisp在CAD二次开发中的总体思想、优点、数据结构、流程等.
