列车接近道口通知电路的改进处理

受地理环境、工程投资等因素限制,诸多地方的铁路与公路平面交叉,必须装设安全可靠的道口信号防护系统以保证铁路道口安全,且应符合故障-安全原则。因此,结合实际工程情况设计相应的道口信号方案具有实际意义。

Modification of Train Approaching Notification Circuit of Level Crossing

Restricted by geographical environment,engineering investment and other factors, many railways have level crossings with highways.So,it is required that a safe and reliable signal protection system must be installed to ensure the safety of railway level crossing,which should conform to the principle of fail-safe.Therefore,a signal design for level crossing is signficance ac- cording to actual engineering condition.
