基于autoCAD平台的CATV辅助设计软件的开发

摘要

为了提高在autoCAD平台上进行CATV系统布线设计效率, 减少绘图人员工作量同时加强CATV系统设计规范及可靠性, 开发了一套基于autoCAD平台的CATV系统辅助设计软件.软件分为包括参数设定模块、绘图模块以及处理模块.利用参数设定模块及绘图模块实现参数录入及平面图初步绘制, 在处理模块中通过定义数据存储结构和设计选型算法实现设备选型、放大器添加、设备数量统计及系统图绘制的自动化.同时为保证CATV系统绘制的规范性, 软件设定了检错机制, 在选型过程中同步检测绘图的规范性.%In order to improve the design efficiency of CATV system on autoCAD platform, reduce the workload of drafters and enhance the design specification and reliability of CATV system, a set of CATV system auxiliary design software based on autoCAD platform was developed. The software is divided into a parameter setting module, a drawing module, and a processing module. Parameter input module and drawing module are used to realize parameter entry and preliminary drawing of the plan. In the processing module, device selection, amplifier addition, device quantity statistics and system diagram drawing automation are realized by defining data storage structure and design selection algorithm. At the same time, in order to ensure the standardization of the CATV system, the software sets the error detection mechanism to synchronously detect the standardization of the drawing during the selection process.
