自动绘制信号室外电缆图软件的改进

Improvement of Auto Drawing of Outdoor Cable Distribution

针对信号设计工作中室外电缆图的设计工作量大,人工配线复杂,容易出错的特点,综合考虑了四线制、二线制电码化的设计要求,以及自动计算电缆长度、芯数和电缆配线的需要,提出了计算机软件辅助设计的思路。利用CAD和软件编程技术,结合室外电缆设备布置相关的规范、标准确定画图原则,并说明软件改进设计的方法和程序运行流程。该软件在实际工作中取得了预期的效果。

The design of outdoor cable layout diagram in signal design features heavy workload,complexity of manual cable distribution,and frequent errors.To address those problems,we put forward a computer-aided design solution of outdoor cable layout diagram in consideration of the design requirements of four-wire and two-wire coded track circuit system as well as other requirements like auto computing cable length,core number,and cable distribution.Using CAD and software programming techniques,the drawing principles are defined according to the regulation and standards related to outdoor cable layout and the methods of software improvement design and program operation process are described.The application of the software in practice has attained expected results.
