摘　　要：针对铁路线路安全保护区平面图制图过程中需要对A、B、虚拟标桩,里程桩标注,人工无法准确确定标桩里程且标注效率较低。现利用AutoCAD接口开发辅助标注插件,插件充分利用多段线特性,并使用一定方法,确定标桩所对应的里程以及在铁路中心线两侧所处位置实现了标注,并将里程信息保存在扩展数据中,借助该数据实现其他类型桩的标注,同时实现数据导出,比例尺设置等功能。实践表明插件易于使用,并提高了工作效率,减少成图时间。插件的实现为类似项目的工程人员提供技术参考。In the process of mapping the safety protection area plan of railway lines,it is necessary to label A,B,virtual stakes,and mileage stakes.Manual labor cannot accurately determine the mileage of stakes and the labeling efficiency is low.In this paper,the AutoCAD interface is used to develop an auxiliary annotation plugin,which fully utilizes the characteristics of multi segment lines and uses certain methods to determine the mileage corresponding to the stakes and achieve annotation on both sides of the railway centerline.The mileage information is saved in the extended data,and other types of stakes are annotated using this data.At the same time,functions such as data export and scale setting are achieved.Practice has shown that plugins are easy to use,and can improve work efficiency and reduce mapping time.The implementation of plugins provides technical reference for engineers in similar projects.
