摘　　要：随着我国铁路列车车速的提高，铁路处理二次事故的时间大大缩短，一些旧方法已不适用，介绍现铁路系统采用的自检式短路分流线以确保铁路安全运行。以铁路信号制式中的极频自动闭塞系统为例，利用数字仿真方法分析这种措施的可行性及可靠性。Along with accelerating the speed of train, the time of processing secondary accidents is greatiy shortened and the previous methods for preventing secondary accidents have been inapplicabile. This peper introduces the self－checking short shunt circuit is the current railway system to assuce safe running` Take the Polar frequency autornatic blocking system for example,the feasibility and reliability of this method are analyzed by Numerical simulation.
