摘　　要：在编组场设置停车器,可以提高调车作业效率,保证调车人员人身安全。此项研究是在计算机联锁系统的基础上开发停车器控制软件,包括软件需求分析和软件设计。在需求分析时,结合场景和图形对自动控制的需求进行分析;软件设计活动设计了基于面向对象的停车器模块,以及软件的总体架构。同时,通过对停车器模块进行建模,重点分析了停车器关联控制区段的算法,以及根据电源屏供电情况,停车器动作数量的算法。采用面向对象的设计方法不仅有助于软件模块化,同时减少对原有程序的影响,提高联锁软件的正确性和安全性。Set up stopping device at the marshalling station can improve the efficiency of shunting operation and ensure personal safety. Our study is to develop the software of stopping control based on computer interlocking system, including software requirement analysis and software design. In requirement analysis, analysis of the demand for automatic control is conducted by combining the scene with graphic. Software design mainly defines an object - oriented stopping module and the overall framework of the software. At the same time, we focus on analyzing the stopping algorithm associated control section by modeling the stopping module as well as the algorithm of stopping device＇s action number according to the condition of the power supply panel. The object oriented design method adopted can not only be conducive to the modularization of the software but also help reduce the impact on the original program, improving the accuracy and safety of the interlocking software.
